and other aspects o...BACKGROUND Painless gastroenteroscopy is a widely developed diagnostic and treatment technology in clinical practice.It is of great significance in the clinical diagnosis,treatment,follow-up review and other aspects of gastric cancer patients.The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort.In clinical work,the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose;the application of opioid drugs often causes gastrointestinal reactions,such as nausea,vomiting and delayed gastrointestinal function recovery,after examination.These adverse effects can seriously affect the quality of life of patients.AIM To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function,related complications and immune function in patients with gastric cancer during and after painless gastroscopy.METHODS A total of 106 patients with gastric cancer,who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy,were randomly divided into a treatment group(n=56)and a control group(n=50).Before the examination,all patients fasted for 8 h,provided their health education,and confirmed if there were contraindications to anesthesia and gastroscopy.During the examination,the patients were placed in the left decubitus position,the patients were given oxygen through a nasal catheter(6 L/min),the welling needle was opened for the venous channel,and a multifunction detector was connected for monitoring electrocardiogram,oxygen saturation,blood pressure,etc.Naporphl and propofol propofol protocols were used for routine anesthesia.Before anesthesia administration,the patients underwent several deep breathing exercises,received intravenous nalbuphine[0.nalbuphine(0.025 mg/kg)],followed by intravenous propofol[1.propofol(1.5 mg/kg)]until the palpebral reflex disappeared,and after no response,gastroscopy was performed.If palpebral reflex disappeared,and after no response,gastroscopy was performed.If any patient developed movement,frowning,or hemodynamic changes during the operation(heart rate changes during the operation(heart rate increased to>20 beats/min,systolic blood pressure increased to>20%of the base value),additional propofol[0.propofol(0.5 mg/kg)]was added until the patient was sedated again.The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination,while the patients in the control group received routine gastrointestinal endoscopy.The patients in the two groups were examined by conventional painless gastroscopy,and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared.These characteristics included the total dosage of propofol during the examination,the incidence of complications during the operation,the time of patients'awakening,the time of independent activities,and the gastrointestinal function of the patients after examination,such as the incidence of reactions such as malignant vomiting,abdominal distension and abdominal pain,as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction(T0),after conscious extubation(T1)and 24 h after surgery(T2).RESULTS There was no difference in the patients’general information,American Society of Anesthesiologist classification or operation time between the two groups before treatment.In terms of painless gastroscopy,the total dosage of propofol in the treatment group was lower than that in the control group(P<0.05),and the time of awakening and autonomous activity was significantly faster than that in the control group(P<0.05).During the examination,the incidence of hypoxemia,hypotension and hiccups in the treatment group was significantly lower than that in the control group(P<0.01).In terms of gastrointestinal function,the incidences of nausea,vomiting,abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group(P<0.01).In terms of immune function,in both groups,the number of CD4+and CD8+cells decreased significantly(P<0.05),and the number of natural killer cells increased significantly(P<0.05)at T1 and T2,compared with T0.The number of CD4+and CD8+cells in the treatment group at the T1 and T2 time points was higher than that in the control group(P<0.05),while the number of natural killer cells was lower than that in the control group(P<0.05).In terms of inflammatory factors,compared with T0,the levels of interleukin(IL)-6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased(P<0.05).The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group(P<0.05).CONCLUSION The preoperative use of modified ShengYangYiwei decoction can optimize the anesthesia program during painless gastroscopy,improve the gastrointestinal function of patients after the operation,reduce the occurrence of examination-related complications.展开更多

Eighteen sows were fed 2 boluses per day of Saccharomyces cerevisiae var. boulardii CMCN-1079 (probiotic;PRO, n = 9) or placebo (CON, n = 9) starting at gestational day (GD) 84 and continuing until 21 days post-farrowing (end of lactation). Sow blood samples were collected every 7 days post-supplementation during gestation and 24-h post-farrowing and end of lactation. Blood samples were taken from 84 female pigs (n = 42 per sow treatment group) at 1, 7, 14, 21, 28, and 35 days old to assess innate and adaptive immune measures. Minimal effects of Scb supplementation were found on sow immune status during gestation and lactation, except for PRO-treated sows that had enhanced neutrophil function (P and mitogen-induced lymphocyte proliferation after 51 days of treatment (P < 0.0001). Overall, pigs from PRO-treated sows had higher C5a- and IL-8-induced neutrophil chemotaxis, NK cytotoxicity, and mitogen-induced B-lymphocyte proliferation than those from CON sows (P inimal effect on the sows but postnatal maternal exposure to Saccharomyces cerevisiae var. boulardii supplementation modulated the immune status of the progeny beyond the lactation period resulting in those from PRO-treated sows having more enhanced neutrophil function and B-cell proliferative response in the short term. Therefore, these data imply that including yeast probiotics in maternal diets may have carry-over effects in priming offspring’s immune function, especially neutrophil function and B-cell proliferation in the short term.展开更多

This review discusses results from several human and animal studies that provide insight into the potential mechanisms of action by which noni juice exerts its immunomodulatory effects. Increased natural killer cell activity is a likely a major contributor to the improved health outcomes and increased survival times described in case reports and as observed in LLC and S180 tumor bearing mice. Increased interferon-gamma (IFN-γ) production is also an important mechanism of action through which noni improves immune function. IFN-γ promotes natural killer cell activity and phagocytosis, activities both seen in human and bovine studies as well as in rodents. Noni promotes regulatory cytokine expression, such as IL-2 which stimulates CD4+ T cell differentiation. Noni juice appears to influence this process via kinase 1/2 (ERK1/2), protein kinase B (Akt) and nuclear factor-kappa-beta signaling. As oxidative status is known to influence immune function, this review also discusses the notable antioxidant properties of noni juice that have been demonstrated in human trials.展开更多

文摘BACKGROUND Human herpesvirus type 7(HHV-7)is a less common herpes virus that usually causes mild,self-limiting illnesses.However,in recent years,there have been increasing reports of HHV-7 causing serious central nervous system infections,especially meningitis.The pathogenesis and clinical features of HHV-7 meningitis,particularly in adolescents with normal immune function,remain incompletely studied.Therefore,the purpose of this report is to share a case of HHV-7 meningitis in an immunocompetent adolescent with a view to deepening our understanding of the disease.CASE SUMMARY A 12-year-old female was admitted with fever,headache,and vomiting.4 d before admission,the patient developed a fever without obvious induction,with a temperature up to 39.5℃,no convulsions,accompanied by chills,headaches,fatigue,and no muscle aches.The patient was treated with fever reduction,which could be reduced to 38℃;repeated high fever,accompanied by vomiting 7-8 times;and no abdominal pain or diarrhea.The patient was diagnosed with"acute suppurative tonsillitis"in a local hospital,and the blood routine was generally normal.The patient was given symptomatic support treatment such as"ceftriaxone sodium"and antiemetic rehydration for 2 d,and his condition did not improve.The patient's physical examination showed pharyngeal congestion,bilateral tonsil grade I hypertrophy,regression of purulent secretions,and cervical resistance.Ocular B-ultrasound:Opacity of the vitreous body and edema of the optic disc in both eyes.Optical coherence tomography examination showed that the macular fovea was generally normal in both eyes,with edema of the optic disc.DNA virus monitoring results:HHV-7.We gave ganciclovir antiviral therapy,dexamethasone anti-inflammatory treatment,mannitol to reduce cranial pressure,omeprazole to protect gastrointestinal mucosa,and calcium and potassium supplementation.CONCLUSION This study reports a case of HHV-7 meningitis in an adolescent with normal immune function.Through comprehensive analysis of the clinical manifestations,laboratory tests,and treatment methods of the patient,it is found that early identification and antiviral treatment are essential for the outcome of the disease.This case suggests that despite normal immune function,adolescents may still suffer from herpes virus type 7 meningitis,so clinicians should be vigilant and take effective treatment measures in time.

文摘In this study,we investigated the effects of major royal jelly proteins(MRJPs)on the estrogen,gut microbiota,and immunological responses in mice.Mice given 250 or 500 mg/kg,not 125 mg/kg of MRJPs,enhanced the proliferation of splenocytes in response to mitogens.The splenocytes and mesenteric lymphocytes activated by T-cell mitogens(Con A and anti-CD3/CD28 antibodies)released high levels of IL-2 but low levels of IFN-γand IL-17A.The release of IL-4 was unaffected by MRJPs.Additionally,splenocytes and mesenteric lymphocytes activated by LPS were prevented by MRJPs at the same dose as that required for producing IL-1βand IL-6,two pro-inflammatory cytokines.The production of IL-1β,IL-6,and IFN-γwas negatively associated with estrogen levels,which were higher in the MRJP-treated animals than in the control group.Analysis of the gut microbiota revealed that feeding mice 250 mg/kg of MRJPs maintained the stability of the natural intestinal microflora of mice.Additionally,the LEf Se analysis identified biomarkers in the MRJP-treated mice,including Prevotella,Bacillales,Enterobacteriales,Gammaproteobacteria,Candidatus_Arthromitus,and Shigella.Our results showed that MRJPs are important components of royal jelly that modulate host immunity and hormone levels and help maintain gut microbiota stability.
文摘BACKGROUND Hepatectomy is the first choice for treating liver cancer.However,inflammatory factors,released in response to pain stimulation,may suppress perioperative immune function and affect the prognosis of patients undergoing hepatectomies.AIM To determine the short-term efficacy of microwave ablation in the treatment of liver cancer and its effect on immune function.METHODS Clinical data from patients with liver cancer admitted to Suzhou Ninth People’s Hospital from January 2020 to December 2023 were retrospectively analyzed.Thirty-five patients underwent laparoscopic hepatectomy for liver cancer(liver cancer resection group)and 35 patients underwent medical image-guided microwave ablation(liver cancer ablation group).The short-term efficacy,complications,liver function,and immune function indices before and after treatment were compared between the two groups.RESULTS One month after treatment,19 patients experienced complete remission(CR),8 patients experienced partial remission(PR),6 patients experienced stable disease(SD),and 2 patients experienced disease progression(PD)in the liver cancer resection group.In the liver cancer ablation group,21 patients experienced CR,9 patients experienced PR,3 patients experienced SD,and 2 patients experienced PD.No significant differences in efficacy and complications were detected between the liver cancer ablation and liver cancer resection groups(P>0.05).After treatment,total bilirubin(41.24±7.35 vs 49.18±8.64μmol/L,P<0.001),alanine aminotransferase(30.85±6.23 vs 42.32±7.56 U/L,P<0.001),CD4+(43.95±5.72 vs 35.27±5.56,P<0.001),CD8+(20.38±3.91 vs 22.75±4.62,P<0.001),and CD4+/CD8+(2.16±0.39 vs 1.55±0.32,P<0.001)were significantly different between the liver cancer ablation and liver cancer resection groups.CONCLUSION The short-term efficacy and safety of microwave ablation and laparoscopic surgery for the treatment of liver cancer are similar,but liver function recovers quickly after microwave ablation,and microwave ablation may enhance immune function.

文摘BACKGROUND Immune dysregulation and metabolic derangement have been recognized as key factors that contribute to the progression of hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF).However,the mechanisms underlying immune and metabolic derangement in patients with advanced HBV-ACLF are unclear.AIM To identify the bioenergetic alterations in the liver of patients with HBV-ACLF causing hepatic immune dysregulation and metabolic disorders.METHODS Liver samples were collected from 16 healthy donors(HDs)and 17 advanced HBV-ACLF patients who were eligible for liver transplantation.The mitochondrial ultrastructure,metabolic characteristics,and immune microenvironment of the liver were assessed.More focus was given to organic acid metabolism as well as the function and subpopulations of macrophages in patients with HBV-ACLF.RESULTS Compared with HDs,there was extensive hepatocyte necrosis,immune cell infiltration,and ductular reaction in patients with ACLF.In patients,the liver suffered severe hypoxia,as evidenced by increased expression of hypoxia-inducible factor-1α.Swollen mitochondria and cristae were observed in the liver of patients.The number,length,width,and area of mitochondria were adaptively increased in hepatocytes.Targeted metabolomics analysis revealed that mitochondrial oxidative phosphorylation decreased,while anaerobic glycolysis was enhanced in patients with HBV-ACLF.These findings suggested that,to a greater extent,hepa-tocytes used the extra-mitochondrial glycolytic pathway as an energy source.Patients with HBV-ACLF had elevated levels of chemokine C-C motif ligand 2 in the liver homogenate,which stimulates peripheral monocyte infiltration into the liver.Characterization and functional analysis of macrophage subsets revealed that patients with ACLF had a high abundance of CD68^(+)HLA-DR^(+)macrophages and elevated levels of both interleukin-1βand transforming growth factor-β1 in their livers.The abundance of CD206^(+)CD163^(+)macrophages and expression of interleukin-10 decreased.The correlation analysis revealed that hepatic organic acid metabolites were closely associated with macrophage-derived cytokines/chemokines.CONCLUSION The results indicated that bioenergetic alteration driven by hypoxia and mitochondrial dysfunction affects hepatic immune and metabolic remodeling,leading to advanced HBV-ACLF.These findings highlight a new therapeutic target for improving the treatment of HBV-ACLF.
文摘BACKGROUND Colon cancer(CC)has a high incidence rate.Radical resection is the main treatment method for CC;however,liver metastasis(LM)often occurs post-surgery.The liver contains both innate and adaptive immune cells that monitor and remove abnormal cells and pathogens.Before LM,tumor cells secrete cytokines and exosomes to adjust the immune microenvironment of the liver,thus forming an inhibitory immune microenvironment for colonization by circulating tumor cells.This indicates that the immune state of patients with CC plays a crucial role in the occurrence and progression of LM.AIM To observe and analyze the relationship between immune status and expression of tumor factors in patients with LM of CC,and to provide a scientific interven-tion method for promoting the patient prognosis.METHODS A retrospective analysis was performed.The baseline data of 100 patients with CC and 100 patients with CC who suffered from postoperative LM and were admitted to our hospital from May 2021 to May 2023 were included in the non-occurrence and occurrence groups,respectively.The immune status of the pa-tients and the expression of tumor factor-related indicators in the two groups were compared,and the predictive value of the indicators for postoperative LM in patients with CC was analyzed.RESULTS Compared with the non-occurrence group,the expression of serum carcinoem-bryonic antigen(CEA),CA19-9,CA242,CA72-4 and CA50 in patients in the occurrence group were significantly higher,while the expression of CD3+,CD4+,CD8+,natural killer(NK)and CD4+/CD25 in patients in the occurrence group were significantly lower(P<0.05).No significant difference was observed in other baseline data between groups(P>0.05).Multivariate logistic regression model analysis revealed that the expressions of CEA,CA19-9,CA242,CA72-4,CA50,CD3+,CD4+,CD8+,NK,and CD4+/CD25 were associated with the LM in patients with CC.High expressions of serum CEA,CA19-9,CA242,CA72-4 and CA50,and low expressions of CD3+,CD4+,CD8+,NK,and CD4+/CD25 in patients with CC were risk factors for LM(OR>1,P<0.05).The receiver operating characteristic curve showed that the area under curve for CEA,CA19-9,CA242,CA72-4,CA50,CD3+,CD4+,CD8+,NK,and CD4+/CD25 in the prediction of LM in patients with CC were all>0.80,with a high predictive value.CONCLUSION The expression of tumor factors and immune state-related indices in patients with CC is closely associated with the occurrence of LM.

文摘BACKGROUND Alzheimer’s disease(AD)is a serious disease causing human dementia and social problems.The quality of life and prognosis of AD patients have attracted much attention.The role of chronic immune inflammation in the pathogenesis of AD is becoming more and more important.AIM To study the relationship among cognitive dysfunction,abnormal cellular immune function,neuroimaging results and poor prognostic factors in patients.METHODS A retrospective analysis of 62 hospitalized patients clinical diagnosed with AD who were admitted to our hospital from November 2015 to November 2020.Collect cognitive dysfunction performance characteristics,laboratory test data and neuroimaging data from medical records within 24 h of admission,including Mini Mental State Examination Scale score,drawing clock test,blood T lymphocyte subsets,and neutrophils and lymphocyte ratio(NLR),disturbance of consciousness,extrapyramidal symptoms,electroencephalogram(EEG)and head nucleus magnetic spectroscopy(MRS)and other data.Multivariate logistic regression analysis was used to determine independent prog-nostic factors.the modified Rankin scale(mRS)was used to determine whether the prognosis was good.The correlation between drug treatment and prognostic mRS score was tested by the rank sum test.RESULTS Univariate analysis showed that abnormal cellular immune function,extrapyramidal symptoms,obvious disturbance of consciousness,abnormal EEG,increased NLR,abnormal MRS,and complicated pneumonia were related to the poor prognosis of AD patients.Multivariate logistic regression analysis showed that the decrease in the proportion of T lym-phocytes in the blood after abnormal cellular immune function(odd ratio:2.078,95%confidence interval:1.156-3.986,P<0.05)was an independent risk factor for predicting the poor prognosis of AD.The number of days of donepezil treatment to improve cognitive function was negatively correlated with mRS score(r=0.578,P<0.05).CONCLUSION The decrease in the proportion of T lymphocytes may have predictive value for the poor prognosis of AD.It is recommended that the proportion of T lymphocytes<55%is used as the cut-off threshold for predicting the poor prog-nosis of AD.The early and continuous drug treatment is associated with a good prognosis.

文摘Background:In China,cage systems with a high space utilization have gradually replaced ground litter systems,but the disease incidence of chickens in cages is higher.Broilers in the ground litter pens may be stimulated by more environmental microbes during the growth process and show strong immune function and status,but knowledge of which microbes and their metabolites play an immunomodulatory role is still limited.This study aimed to explore the differences and correlations in the immune function,gut microbiota and metabolites and the importance of gut microbiota of broilers raised in cages and ground litter pens.Methods:The experiment involved a 2×2 factorial arrangement,with rearing systems(cages or ground litter pens)and antibiotic treatment(with or without broad-spectrum antibiotics in drinking water)as factors.Results:The results showed that,compared with the cage group,the ground litter broilers had stronger nonspecific immune function(Macrophages%and NO in blood),humoral immune function(IgG in blood,LPS stimulation index in ileum)and cellular immune function(T%,Tc%,ConA stimulation index and cytokines in blood).Antibiotic(ABX)treat-ment significantly reduced nonspecific immune function(Macrophages%and NO in blood,iNOS and Mucin2 mRNA expression in ileum),humoral immune function(IgG in blood and sIgA in ileum)and cellular immune function(T%and cytokines in blood,Th and Tc ratio,TLRs and cytokines mRNA expression in ileum).Furthermore,the ground litter broil-ers had higherαdiversity of microbiota in ileum.The relative abundance of Staphylococcus,Jeotgalicoccus,Jeotgalibaca and Pediococcus in the ileum of ground litter broilers were higher.ABX treatment significantly reduced theαdiversity of ileal microbiota,with less Chloroplast and Mitochondria.In addition,the levels of acetic acid,isobutyric acid,kynurenic acid and allolithocholic acid in the ileum of ground litter broilers were higher.Spearman correlation analysis showed that Jeotgalibaca,Pediococcus,acetic acid,kynurenic acid and allolithocholic acid were related to the immune function.Conclusions:There were more potential pathogens,litter breeding bacteria,short-chain fatty acids,kynurenine,allolithocholic acid and tryptophan metabolites in the ileum of broilers in ground litter pens,which may be the reason for its stronger immune function and status.

文摘BACKGROUND Immune cells play an important role in regulating the behavior of tumor cells.According to emerging evidence,six-transmembrane epithelial antigen of the prostate 4(STEAP4)performs a crucial part in tumor microenvironmental immune response and tumorigenesis,and serves as the potential target for cellular and antibody immunotherapy.However,the immunotherapeutic role of STEAP4 in gastric cancer(GC)remains unclear.AIM To investigate the expression of STEAP4 in GC and its relationship with immune infiltrating cells,and explore the potential value of STEAP4 as an immune prognostic indicator in GC.METHODS The expression level of STEAP4 was characterized by immunohistochemistry in tumors and adjacent non-cancerous samples in 96 GC patients.Tumor Immune Estimation Resource was used to study the correlation between STEAP4 and tumor immune infiltration level and immune infiltration gene signature.R package was used to analyze the relationship between STEAP4 expression and immune and stromal scores in GC(GSE62254)by the ESTIMATE algorithm,and Kaplan-Meier Plotter and Gene Expression Profiling Interactive Analysis were applied to analyze the effect of STEAP4 on clinical prognosis.RESULTS Immunohistochemistry analysis showed that STEAP4 expression was higher in GC tissues than in adjacent tissues,and STEAP4 expression was positively correlated with the clinical stage of GC.In GC,the expression of STEAP4 was positively correlated with the infiltration levels of B cells,CD4+T cells,macrophages,neutrophils,and dendritic cells.The expression level of STEAP4 was strongly correlated with most of the immune markers.In addition,STEAP4 expression was inversely correlated with tumor purity,but correlated with stromal score(r=0.43,P<0.001),immune score(r=0.29,P<0.001)and estimate score(r=0.39,P<0.001).Moreover,stromal,immune,and estimate scores were higher in the STEAP4 high expression group,whereas tumor purity was higher in the STEAP4 Low expression group.The relationship between STEAP4 expression and prognosis of patients with GC was further investigated,and the results showed that high STEAP4 expression was associated with poor overall survival and disease-free survival.In addition,Kaplan-Meier Plotter showed that high expression of STEAP4 was significantly correlated with poor survival of patients with GC.CONCLUSION The current findings suggest an oncogenic role for STEAP4 in GC,with significantly high levels being associated with poor prognosis.Investigation of the GC tumor microenvironment suggests the potential function of STEAP4 is connected with the infiltration of diverse immune cells,which may contribute to the regulation of the tumor microenvironment.In conclusion,STEAP4 may serve as a potential therapeutic target for GC to improve the immune infiltration,as well as serve as a prognostic biomarker for judging the prognosis and immune infiltration status of GC.

文摘BACKGROUND Painless gastroenteroscopy is a widely developed diagnostic and treatment technology in clinical practice.It is of great significance in the clinical diagnosis,treatment,follow-up review and other aspects of gastric cancer patients.The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort.In clinical work,the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose;the application of opioid drugs often causes gastrointestinal reactions,such as nausea,vomiting and delayed gastrointestinal function recovery,after examination.These adverse effects can seriously affect the quality of life of patients.AIM To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function,related complications and immune function in patients with gastric cancer during and after painless gastroscopy.METHODS A total of 106 patients with gastric cancer,who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy,were randomly divided into a treatment group(n=56)and a control group(n=50).Before the examination,all patients fasted for 8 h,provided their health education,and confirmed if there were contraindications to anesthesia and gastroscopy.During the examination,the patients were placed in the left decubitus position,the patients were given oxygen through a nasal catheter(6 L/min),the welling needle was opened for the venous channel,and a multifunction detector was connected for monitoring electrocardiogram,oxygen saturation,blood pressure,etc.Naporphl and propofol propofol protocols were used for routine anesthesia.Before anesthesia administration,the patients underwent several deep breathing exercises,received intravenous nalbuphine[0.nalbuphine(0.025 mg/kg)],followed by intravenous propofol[1.propofol(1.5 mg/kg)]until the palpebral reflex disappeared,and after no response,gastroscopy was performed.If palpebral reflex disappeared,and after no response,gastroscopy was performed.If any patient developed movement,frowning,or hemodynamic changes during the operation(heart rate changes during the operation(heart rate increased to>20 beats/min,systolic blood pressure increased to>20%of the base value),additional propofol[0.propofol(0.5 mg/kg)]was added until the patient was sedated again.The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination,while the patients in the control group received routine gastrointestinal endoscopy.The patients in the two groups were examined by conventional painless gastroscopy,and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared.These characteristics included the total dosage of propofol during the examination,the incidence of complications during the operation,the time of patients'awakening,the time of independent activities,and the gastrointestinal function of the patients after examination,such as the incidence of reactions such as malignant vomiting,abdominal distension and abdominal pain,as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction(T0),after conscious extubation(T1)and 24 h after surgery(T2).RESULTS There was no difference in the patients’general information,American Society of Anesthesiologist classification or operation time between the two groups before treatment.In terms of painless gastroscopy,the total dosage of propofol in the treatment group was lower than that in the control group(P<0.05),and the time of awakening and autonomous activity was significantly faster than that in the control group(P<0.05).During the examination,the incidence of hypoxemia,hypotension and hiccups in the treatment group was significantly lower than that in the control group(P<0.01).In terms of gastrointestinal function,the incidences of nausea,vomiting,abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group(P<0.01).In terms of immune function,in both groups,the number of CD4+and CD8+cells decreased significantly(P<0.05),and the number of natural killer cells increased significantly(P<0.05)at T1 and T2,compared with T0.The number of CD4+and CD8+cells in the treatment group at the T1 and T2 time points was higher than that in the control group(P<0.05),while the number of natural killer cells was lower than that in the control group(P<0.05).In terms of inflammatory factors,compared with T0,the levels of interleukin(IL)-6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased(P<0.05).The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group(P<0.05).CONCLUSION The preoperative use of modified ShengYangYiwei decoction can

文摘BACKGROUND Gastric ulcer(GU)is a common digestive tract disease,and medical records of GU combined with depression are increasingly common.Currently,the risk factors and pathogenesis of GU complicated with depression remain unclear.Low immune function and gastrointestinal hormone levels may also be significant risk factors.Therefore,this study explored the immune function and gastrointestinal hormone levels in patients with GU combined with depression.AIM To explore the immune function,gastrointestinal hormone level,and clinical significance of patients with GU combined with depression.METHODS A retrospective analysis was conducted on 300 patients with GU combined with depression admitted to Guizhou Provincial People’s Hospital from January 2021 to June 2022 as the study subjects.According to the Hamilton Depression Scale(HAMD)score,patients were divided into mild-to-moderate(n=210)and heavy(n=90)groups.Basic data,immune function indices[immunoglobulin A(IgA),IgM,IgG,serum CD4+and CD8+percentage,and CD4+/CD8+ratio],and gastrointestinal hormone indices[serum gastrin(GAS),cholecystokinin(CCK),and motilin(MTL)levels]were collected.The basic data of the two groups were compared,and the immune function and gastrointestinal hormone indices were analyzed.Multivariate logistic regression was used to analyze the factors influencing the severity of GU complicated with depression.The receiver operating characteristic(ROC)curve and area under the ROC curve(AUC)were used to analyze the value of the immune function index,gastrointestinal hormone index,and combined index in predicting the severity of GU complicated with depression.RESULTS There were no marked differences in sex,age,body mass index,abdominal distension,abdominal pain,belching,nausea,vomiting,or sleep disorders between the heavy and mild-to-moderate groups(P>0.05).There was a marked difference in the family history of depression between the heavy and mild-to-moderate groups(P<0.05).There were significant differences in serum IgA and IgM levels and serum CD4+,CD8+,and CD4+/CD8+ratios between the heavy and mild-to-moderate groups(P<0.05).Multivariate analysis showed that IgA,IgM,GAS,and CCK serum levels influenced the severity of GU with depression(P<0.05).The AUC of the ROC curve for serum IgA level predicting GU with depression severity was 0.808[95%confidence interval(CI):0.760-0.857],the AUC of the serum IgM level was 0.757(95%CI:0.700-0.814),the AUC of the serum GAS level was 0.853(95%CI:0.810-0.897),the AUC of the serum CCK level was 0.762(95%CI:0.709-0.822),the AUC of immune function(IgA,IgM)and gastrointestinal hormone levels(GAS,CCK)for the prediction of GU with depression severity was 0.958(95%CI:0.933-0.976).CONCLUSION Important factors influencing GU complicated with depression are serum IgA,IgM,GAS,and CCK indicators.They can be used as indicators to predict the severity of GU complicated with depression.

文摘In traditional finite-temperature Kohn–Sham density functional theory(KSDFT),the partial occupation of a large number of high-energy KS eigenstates restricts the use of first-principles molecular dynamics methods at extremely high temperatures.However,stochastic density functional theory(SDFT)can overcome this limitation.Recently,SDFT and the related mixed stochastic–deterministic density functional theory,based on a plane-wave basis set,have been implemented in the first-principles electronic structure software ABACUS[Q.Liu and M.Chen,Phys.Rev.B 106,125132(2022)].In this study,we combine SDFT with the Born–Oppenheimer molecular dynamics method to investigate systems with temperatures ranging from a few tens of eV to 1000 eV.Importantly,we train machine-learning-based interatomic models using the SDFT data and employ these deep potential models to simulate large-scale systems with long trajectories.Subsequently,we compute and analyze the structural properties,dynamic properties,and transport coefficients of warm dense matter.

文摘Local ischemia often causes a series of inflammatory reactions when both brain immune cells and the peripheral immune response are activated.In the human body,the gut and lung are regarded as the key reactional targets that are initiated by brain ischemic attacks.Mucosal microorganisms play an important role in immune regulation and metabolism and affect blood-brain barrier permeability.In addition to the relationship between peripheral organs and central areas and the intestine and lung also interact among each other.Here,we review the molecular and cellular immune mechanisms involved in the pathways of inflammation across the gut-brain axis and lung-brain axis.We found that abnormal intestinal flora,the intestinal microenvironment,lung infection,chronic diseases,and mechanical ventilation can worsen the outcome of ischemic stroke.This review also introduces the influence of the brain on the gut and lungs after stroke,highlighting the bidirectional feedback effect among the gut,lungs,and brain.
文摘The primary objective of this study was to evaluate the potential immunomodulatory effect of maternal supplementation of Saccharomyces cerevisiae var. boulardii (Scb) from late gestation until the end of lactation on the immune phenotype of her progeny. Eighteen sows were fed 2 boluses per day of Saccharomyces cerevisiae var. boulardii CMCN-1079 (probiotic;PRO, n = 9) or placebo (CON, n = 9) starting at gestational day (GD) 84 and continuing until 21 days post-farrowing (end of lactation). Sow blood samples were collected every 7 days post-supplementation during gestation and 24-h post-farrowing and end of lactation. Blood samples were taken from 84 female pigs (n = 42 per sow treatment group) at 1, 7, 14, 21, 28, and 35 days old to assess innate and adaptive immune measures. Minimal effects of Scb supplementation were found on sow immune status during gestation and lactation, except for PRO-treated sows that had enhanced neutrophil function (P and mitogen-induced lymphocyte proliferation after 51 days of treatment (P < 0.0001). Overall, pigs from PRO-treated sows had higher C5a- and IL-8-induced neutrophil chemotaxis, NK cytotoxicity, and mitogen-induced B-lymphocyte proliferation than those from CON sows (P inimal effect on the sows but postnatal maternal exposure to Saccharomyces cerevisiae var. boulardii supplementation modulated the immune status of the progeny beyond the lactation period resulting in those from PRO-treated sows having more enhanced neutrophil function and B-cell proliferative response in the short term. Therefore, these data imply that including yeast probiotics in maternal diets may have carry-over effects in priming offspring’s immune function, especially neutrophil function and B-cell proliferation in the short term.
文摘Morinda citrifolia (noni) fruit juice has the potential to influence immune system function. This review discusses results from several human and animal studies that provide insight into the potential mechanisms of action by which noni juice exerts its immunomodulatory effects. Increased natural killer cell activity is a likely a major contributor to the improved health outcomes and increased survival times described in case reports and as observed in LLC and S180 tumor bearing mice. Increased interferon-gamma (IFN-γ) production is also an important mechanism of action through which noni improves immune function. IFN-γ promotes natural killer cell activity and phagocytosis, activities both seen in human and bovine studies as well as in rodents. Noni promotes regulatory cytokine expression, such as IL-2 which stimulates CD4+ T cell differentiation. Noni juice appears to influence this process via kinase 1/2 (ERK1/2), protein kinase B (Akt) and nuclear factor-kappa-beta signaling. As oxidative status is known to influence immune function, this review also discusses the notable antioxidant properties of noni juice that have been demonstrated in human trials.

文摘The process of entrainment-mixing between cumulus clouds and the ambient air is important for the development of cumulus clouds.Accurately obtaining the entrainment rate(λ)is particularly important for its parameterization within the overall cumulus parameterization scheme.In this study,an improved bulk-plume method is proposed by solving the equations of two conserved variables simultaneously to calculateλof cumulus clouds in a large-eddy simulation.The results demonstrate that the improved bulk-plume method is more reliable than the traditional bulk-plume method,becauseλ,as calculated from the improved method,falls within the range ofλvalues obtained from the traditional method using different conserved variables.The probability density functions ofλfor all data,different times,and different heights can be well-fitted by a log-normal distribution,which supports the assumed stochastic entrainment process in previous studies.Further analysis demonstrate that the relationship betweenλand the vertical velocity is better than other thermodynamic/dynamical properties;thus,the vertical velocity is recommended as the primary influencing factor for the parameterization ofλin the future.The results of this study enhance the theoretical understanding ofλand its influencing factors and shed new light on the development ofλparameterization.

文摘Background To improve our understanding of host and intestinal microbiome interaction,this research investigated the effects of a high-level zinc oxide in the diet as model intervention on the intestinal microbiome and small intestinal functionality in clinically healthy post-weaning piglets.In study 1,piglets received either a high concentration of zinc(Zn)as zinc oxide(Zn O,Zn,2,690 mg/kg)or a low Zn concentration(100 mg/kg)in the diet during the post weaning period(d 14–23).The effects on the piglet's small intestinal microbiome and functionality of intestinal tissue were investigated.In study 2,the impact of timing of the dietary zinc intervention was investigated,i.e.,between d 0–14 and/or d 14–23 post weaning,and the consecutive effects on the piglet's intestinal functionality,here referring to microbiota composition and diversity and gene expression profiles.Results Differences in the small intestinal functionality were observed during the post weaning period between piglets receiving a diet with a low or high concentration Zn O content.A shift in the microbiota composition in the small intestine was observed that could be characterized as a non-pathological change,where mainly the commensals inter-changed.In the immediate post weaning period,i.e.,d 0–14,the highest number of differentially expressed genes(DEGs)in intestinal tissue were observed between animals receiving a diet with a low or high concentration Zn O content,i.e.,23 DEGs in jejunal tissue and 11 DEGs in ileal tissue.These genes are involved in biological processes related to immunity and inflammatory responses.For example,genes CD59 and REG3G were downregulated in the animals receiving a diet with a high concentration Zn O content compared to low Zn O content in both jejunum and ileum tissue.In the second study,a similar result was obtained regarding the expression of genes in intestinal tissue related to immune pathways when comparing piglets receiving a diet with a high concentration Zn O content compared to low Zn O content.Conclusions Supplementing a diet with a pharmaceutical level of Zn as Zn O for clinically healthy post weaning piglets influences various aspects intestinal functionality,in particular in the first two weeks post-weaning.The model intervention increased both the alpha diversity of the intestinal microbiome and the expression of a limited number of genes linked to the local immune system in intestinal tissue.The effects do not seem related to a direct antimicrobial effect of Zn O.
文摘Objective:To investigate the efficacy and immune function of thyroid stimulating hormone(TSH)suppression therapy in postoperative thyroid cancer patients.Methods:Sixty thyroid cancer patients admitted from July 2020–July 2022 were recruited and randomly divided into two groups.The control group(30 patients)received hormone replacement therapy,while the study group(30 patients)received TSH suppression therapy.The thyroid function,clinical efficacy,immune function,and tumor markers of the two groups were compared.Results:After treatment,the levels of free triiodothyronine(FT3)and thyroxine(FT4)in both groups increased significantly,while TSH levels decreased significantly.Moreover,the magnitude of change in the study group was greater than that in the control group(P<0.05).The total effective rate in the study group was significantly higher as compared to the control group(P<0.05).After treatment,the levels of CD3+and CD4+cells in both groups of patients increased significantly,with the study group showing significantly higher levels than the control group,whereas the level of CD8+cells decreased significantly,with the study group having lower levels than the control group(P<0.05).After treatment,the levels of Tg and CEA in both groups were significantly lowered as compared to before treatment,and the levels of Tg and CEA in the study group were significantly lower than the control group(P<0.05).Conclusion:TSH suppression therapy in postoperative thyroid cancer patients can improve thyroid function,suppress the levels of tumor markers,and enhance immune function,thereby achieving good clinical outcomes.
文摘Objective:To investigate the effect of Kangfuxin Solution(康复新液)combined with low-level laser therapy(LLLT)on cytokines and immune function in patients with radiation-induced oral mucositis.Methods:There were 84 nasopharyngeal carcinoma patients with oral mucositis after intensity-modulated radiation therapy(IMRT)were randomly divided into the control group(CG)and the observation group(OG),with 42 cases in each group.The CG was given LLLT,and the OG was treated with Kangfuxin Solution in addition to LLLT for 10 consecutive days.The healing time of oral mucosa,mucositis grading,oral pain scores,cytokines(interleukin-6,interleukin-1βand tumor necrosis factor-α)and T lymphocyte subsets were compared between the 2 groups before and after treatment.Results:The healing time of oral mucosa in the OG was(6.8±1.4)d,which was significantly shorter than(8.6±1.9)d in the CG(t=4.943,P<0.01).After treatment,the grading of oral mucositis in the OG was better than that in the CG,with a statistically significant difference(Z=2.942,P<0.05).The oral pain scores of the OG was lower than that in the CG at different time points after treatment,and the difference was statistically significant(t=8.207,11.017,P<0.01).After treatment,the levels of IL-6,IL-1βand TNF-αin peripheral blood of the OG were significantly lower than those in the CG(t=5.217,2.775,4.053,P<0.01).There were statistically significant differences in CD4+,CD8+and CD4+/CD8+between the OG and the CG after treatment(t=5.692,6.093,3.658,P<0.01).Conclusion:Kangfuxin Solution combined with LLLT can significantly shorten the healing time of oral mucosal,reduce the grading of oral mucositis,relieve oral pain,reduce inflammatory response and improve the immune function of patients.

文摘Advanced mesenchymal stromal cell-based therapies for neurodegenerative diseases are widely investigated in preclinical models.Mesenchymal stromal cells are well positioned as therapeutics because they address the underlying mechanisms of neurodegeneration,namely trophic factor deprivation and neuroinflammation.Most studies have focused on the beneficial effects of mesenchymal stromal cell transplantation on neuronal survival or functional improvement.However,little attention has been paid to the interaction between mesenchymal stromal cells and the host immune system due to the immunomodulatory properties of mesenchymal stromal cells and the long-held belief of the immunoprivileged status of the central nervous system.Here,we review the crosstalk between mesenchymal stromal cells and the immune system in general and in the context of the central nervous system,focusing on recent work in the retina and the importance of the type of transplantation.
