Treatment and exploration of integrated traditional Chinese and Western medicine for hypertension

At present,hypertension has the phenomenon of increasing incidence and advancing age of onset.It can be complicated by various cardiovascular and cerebrovascular diseases and has a poor prognosis.Its pathogenesis is related to vascular endothelial injury and its mediated inflammation,blood flow,changes in mechanical force,and vascular remodeling.Vascular biomechanical changes are the early and critical pathogenic factors of this disease.Mechanosensitive ion channels and their proteins affect the pathological process of hypertension by improving cell membrane tension,regulating vascular tension and contractility,and participating in vascular biomechanical changes such as vascular remodeling.However,the drugs currently used to treat high blood pressure only slow the progression of the disease.Therefore,it is necessary to find and study effective medicines to treat hypertension.At present,modern medical methods do not have targeted treatment measures.Traditional Chinese medicine plays a significant role in treating this disease based on the principle of“treatment according to the syndrome”.Traditional Chinese medicine regulates the mechanical force of blood flow and maintains blood pressure balance in patients with hypertension.There are many kinds of Chinese patent medicines used to treat hypertension with good curative effects.

Treatment and prevention of diabetes complicated with non-alcoholic fatty liver disease by integrated traditional Chinese and Western medicine

Today’s social economy and science and technology levels are developing rapidly.Type 2 diabetes mellitus(T2DM)is increasing in incidence,and T2DM promotes non-alcoholic fatty liver disease(NAFLD)through some mechanisms.The pathogenesis of T2DM and NAFLD is interconnected,interacted with,and promoted.While increasing the economic burden on patients,it also affects the quality and life of patients themselves.In the world,the current treatment methods include exercise and diet control,drugs(including sugar reduction,lipid-lowering drugs,etc.),weight loss surgery,etc.,but currently,researching drugs can only control the progress of the disease.At present,there is no drug for T2DM combined with NAFLD treatment.Therefore,it is necessary to find and study effective drugs for NAFLD.Based on the principle of“syndrome differentiation,”traditional Chinese medicine(TCM)played an important role in treating this disease.The theory of TCM believes that the cause of NAFLD is mostly diet disorders and imbalances in daily life,leading to liver Qi stagnation,spleen dysfunction,and liver and kidney deficiency,producing phlegm and stasis.During the treatment process,we must pay attention to the goal of phlegm turbidity,but also pay attention to the source of phlegm turbidity,strengthen the spleen and stomach,nourish the liver and kidney,and restore the physiological function of the body.The ingredients of Chinese medicine extracts have the effects of antagonist oxidation stress,protecting liver cells,improving fibrous soluble systems,and promoting lipid metabolism,thereby reducing inflammatory factors to release damage to liver cells.By combining the diagnosis of TCM syndromes with Western medical disease diagnosis,the model of disease diagnosis combined with syndrome differentiation can compensate for some of the limitations of TCM’s sole reliance on syndrome differentiation,allowing for a better grasp of the disease.In treatment,a dual approach using traditional Chinese and Western medicine can enhance efficacy and reduce toxicity,leveraging both complementary strengths.Chinese medicine explains its treatment of NAFLD from a macro and micro level,providing a safer and more effective method for treating the disease.

Clinical Study on Treatment of Severe Acute Pancreatitis by Integrative Chinese and Western Medicine Combined with Somatostatin

Objective: To study whether the therapeutic effect could be enhanced by combined use of somatostatin and conventional integrative Chinese and western medicine (TCM-WM) in treating severe acute pancreatitis (SAP). Methods: Sixty patients of SAP were randomly divided equally into the somatostatin group (Group A) and the basis treated group , they were all treated with non-surgical TCM-WM treatment, but to Group A, the intravenous injection of somatostatin 250 μg/h for 72 hrs continuously was given additionally. Laboratory parameters, condition of disease and therapeutic effect indexes, including occurrence of organic dysfunction, local complication and mortality, between the two groups were compared. Results: The recovery of serum levels of amylase, lipase, C reaction protein, lactate dehydrogenase, aspartate aminotransferase, as well as the scores of APACHE Ⅱ in Group A were quicker than those in Group B (P<0 05). The occurrence of organic dysfunction and local com plication in Group A were lower to those in Group B, but without statistic significance. Comparison of the mortality in the two groups showed insignificant difference ( P> 0 05). Conclusion: The early stage short course of combined TCM-WM and somatostatin treatment could improve the condition of SAP, but its effect on mortality should be further verified by enlarging the sample size.

Effect and mechanism of Qingre Huashi decoction on drug-resistant Helicobacter pylori

BACKGROUND Helicobacter pylori(HP),the most common pathogenic microorganism in stomach,can induce inflammatory reactions in the gastric mucosa,causing chronic gastritis and even gastric cancer.HP infection affects over 4.4 billion people globally,with a worldwide infection rate of up to 50%.The multidrug resistance of HP poses a serious challenge to eradication.It has been monstrated that compared to bismuth quadruple therapy,Qingre Huashi decoction(QHD)combined with triple therapy exhibits comparable eradication rates but with a lower incidence of adverse reactions;in addition,QHD directly inhibit and kill HP in vitro.METHODS In this study,12 HP strains were isolated in vitro after biopsy during gastroscopy of HP-infected patients.In vitro,the minimum inhibitory concentration(MIC)values for clinical HP strains and biofilm quantification were determined through the E-test method and crystal violet staining,respectively.The most robust biofilm-forming strain of HP was selected,and QHD was evaluated for its inhibitory and bactericidal effects on the strain with strong biofilm formation.This assessment was performed using agar dilution,E-test,killing dynamics,and transmission electron microscopy(TEM).The study also explored the impact of QHD on antibiotic resistance in these HP strains with strong biofilm formation.Crystalline violet method,scanning electron microscopy,laser confocal scanning microscopy,and(p)ppGpp chromatographic identification were employed to evaluate the effect of QHD on biofilm in strong biofilm-forming HP strains.The effect of QHD on biofilm and efflux pump-related gene expression was evaluated by quantitative polymerase chain reaction.Non-targeted metabolomics with UHPLC-MS/MS was used to identify potential metabolic pathways and biomarkers which were different between the NC and QHD groups.RESULTS HP could form biofilms of different degrees in vitro,and the intensity of formation was associated with the drug resistance of the strain.QHD had strong bacteriostatic and bactericidal effects on HP,with MICs of 32-64 mg/mL.QHD could inhibit the biofilm formation of the strong biofilm-forming HP strains,disrupt the biofilm structure,lower the accumulation of(p)ppGpp,decrease the expression of biofilm-related genes including LuxS,Spot,glup(HP1174),NapA,and CagE,and reduce the expression of efflux pump-related genes such as HP0605,HP0971,HP1327,and HP1489.Based on metabolomic analysis,QHD induced oxidative stress in HP,enhanced metabolism,and potentially inhibited relevant signaling pathways by upregulating adenosine monophosphate(AMP),thereby affecting HP growth,metabolism,and protein synthesis.CONCLUSION QHD exerts bacteriostatic and bactericidal effects on HP,and reduces HP drug resistance by inhibiting HP biofilm formation,destroying its biofilm structure,inhibiting the expression of biofilm-related genes and efflux pump-related genes,enhancing HP metabolism,and activating AMP in HP.

Construction of the underlying circRNA-miRNA-mRNA regulatory network and a new diagnostic model in ulcerative colitis by bioinformatics analysis

BACKGROUND Circular RNAs(circRNAs)are involved in the pathogenesis of many diseases through competing endogenous RNA(ceRNA)regulatory mechanisms.AIM To investigate a circRNA-related ceRNA regulatory network and a new predictive model by circRNA to understand the diagnostic mechanism of circRNAs in ulcerative colitis(UC).METHODS We obtained gene expression profiles of circRNAs,miRNAs,and mRNAs in UC from the Gene Expression Omnibus dataset.The circRNA-miRNA-mRNA network was constructed based on circRNA-miRNA and miRNA-mRNA interactions.Functional enrichment analysis was performed to identify the biological mechanisms involved in circRNAs.We identified the most relevant differential circRNAs for diagnosing UC and constructed a new predictive nomogram,whose efficacy was tested with the C-index,receiver operating characteristic curve(ROC),and decision curve analysis(DCA).RESULTS A circRNA-miRNA-mRNA regulatory network was obtained,containing 12 circRNAs,three miRNAs,and 38 mRNAs.Two optimal prognostic-related differentially expressed circRNAs,hsa_circ_0085323 and hsa_circ_0036906,were included to construct a predictive nomogram.The model showed good discrimination,with a C-index of 1(>0.9,high accuracy).ROC and DCA suggested that the nomogram had a beneficial diagnostic ability.CONCLUSION This novel predictive nomogram incorporating hsa_circ_0085323 and hsa_circ_0036906 can be conveniently used to predict the risk of UC.The circRNa-miRNA-mRNA network in UC could be more clinically significant.

Effects of invigorating-spleen and anticancer prescription on extracellular signal-regulated kinase/mitogen-activated protein kinase signaling pathway in colon cancer mice model

BACKGROUND Colon cancer(CC)is one of the most common malignant tumors in the gastrointestinal system.Overall,CC had the third highest incidence but the second highest mortality rate globally in 2020.Nowadays,CC is mainly treated with capecitabine chemotherapy regimen,supplemented by radiotherapy,immunotherapy and targeted therapy,but there are still limitations,so Chinese medicine plays an important role.AIM To investigate the effects of invigorating-spleen and anticancer prescription(ISAP)on body weight,tumor inhibition rate and expression levels of proteins in extracellular-signal-regulated kinase(ERK)/mitogen-activated protein kinase(MAPK)signaling pathway in CC mice model.METHODS The CC mice model were established and the mice were randomly divided into 5 groups,including the control group,capecitabine group,the low-dose,mediumdose and high-dose groups of ISAP,with 8 mice in each group,respectively.After 2 weeks of intervention,the body weight and tumor inhibition rate of mice were observed,and the expression of RAS,ERK,phosphorylated ERK(p-ERK),C-MYC and matrix metalloproteinase 2(MMP2)proteins in the tissues of tumors were detected.RESULTS Compared with the control group,the differences of body weight before and after treatment was much smaller in the groups of ISAP,with the smallest difference in the high-dose group of ISAP,while the capecitabine group had the greatest difference,indicating ISAP had a significant inhibiting effect on the growth of transplanted tumor in mice.The expression of RAS protein was decreased in the low-and medium-dose groups of ISAP,and the change of p-ERK was significant in the medium-and high-dose groups of ISAP.MMP2 protein expression was significantly decreased in both the low-dose and medium-dose groups of ISAP.There were no significant changes in ERK in the ISAP group compared to the capecitabine group,while RAS,MMP2,and C-MYC protein expression were reduced in the ISAP group.The expression level of C-MYC protein decreased after treated with ISAP,and the decrease was the most significant in the medium-dose group of ISAP.CONCLUSION ISAP has a potential inhibiting effect on transplanted tumor in mice,and could maintain the general conditions,physical strength and body weight of mice.The expression levels of RAS,p-ERK,MMP2 and c-myc were also decreased to a certain extent.By inhibiting the expression of upstream proteins,the expression levels of downstream proteins in ERK/MAPK signaling pathway were significantly decreased.Therefore,it can be concluded that ISAP may exert an anti-tumor effect by blocking the ERK/MAPK signaling pathway and inhibiting the expression of MMP2 and c-myc proteins.

Clinical significance of platelet mononuclear cell aggregates in patients with sepsis and acute respiratory distress syndrome

BACKGROUND The diagnosis of sepsis combined with acute respiratory distress syndrome(ARDS)has increased owing to the enhanced awareness among medical profes-sionals and the continuous development of modern medical technologies,while early diagnosis of ARDS still lacks specific biomarkers.One of the main patho-genic mechanisms of sepsis-associated ARDS involves the actions of various pathological injuries and inflammatory factors,such as platelet and white blood cells activation,leading to an increase of surface adhesion molecules.These adhesion molecules further form platelet-white blood cell aggregates,including platelet-mononuclear cell aggregates(PMAs).PMAs has been identified as one of the markers of platelet activation,here we hypothesize that PMAs might play a potential biomarker for the early diagnosis of this complication.METHODS We selected 72 hospitalized patients diagnosed with sepsis as the study population between March 2019 and March 2022.Among them,30 patients with sepsis and ARDS formed the study group,while 42 sepsis patients without ARDS comprised the control group.After diagnosis,venous blood samples were imme-diately collected from all patients.Flow cytometry was employed to analyze the expression of PMAs,platelet neutrophil aggregates(PNAs),and platelet aggregates(PLyAs)in the serum.Additionally,the Acute Physiology and Chronic Health Evaluation(APACHE)II score was calculated for each patient,and receiver operating characteristic curves were generated to assess diagnostic value.RESULTS The study found that the levels of PNAs and PLyAs in the serum of the study group were higher than those in the control group,but the difference was not statistically significant(P>0.05).However,the expression of PMAs in the serum of the study group was significantly upregulated(P<0.05)and positively correlated with the APACHE II score(r=0.671,P<0.05).When using PMAs as a diagnostic indicator,the area under the curve value was 0.957,indicating a high diagnostic value(P<0.05).Furthermore,the optimal cutoff value was 8.418%,with a diagnostic sensitivity of 0.819 and specificity of 0.947.CONCLUSION In summary,the serum levels of PMAs significantly increase in patients with sepsis and ARDS.Therefore,serum PMAs have the potential to become a new biomarker for clinically diagnosing sepsis complicated by ARDS.

Systematic functional interrogation of genome-wide association studies locus 17p13.3 deciphered role and genetic control of FAM57A in colorectal cancer development

Objective: Genome-wide association studies(GWAS) have identified over 150 risk loci linked to colorectal cancer(CRC), including the 17p13.3 locus with the tag single nucleotide polymorphism(SNP) rs12603526 in the Asian population. However, the specific causal gene and the functional regulatory mechanisms in this region remain unresolved, necessitating further investigation to elucidate the underlying mechanisms of CRC.Methods: We employed an RNA interference-based functional approach to identify genes critical for CRC cell proliferation at the GWAS locus 17p13.3. Bioinformatic fine-mapping analysis was conducted to prioritize causal variants. A large-scale study involving 7,013 cases and 7,329 controls from a Chinese population, along with another cohort of 5,158 cases and 20,632 controls from the UK Biobank, was performed to validate the association between the candidate variant and the gene. A series of biological experiments was conducted to explore the function of the candidate gene and its regulatory mechanisms.Results: We identified FAM57A as a key oncogene that promotes CRC cell proliferation, and confirmed its carcinogenic role through in vitro proliferation assays. The variant rs526835 was prioritized as a causal candidate for CRC risk, located in a functional region with enhancer properties, and showed a significant quantitative association with FAM57A expression. The rs526835 [T] variant was associated with a 1.17-fold increase in CRC risk [95%confidence interval(95% CI): 1.11-1.23, P=1.23×10^(−9)] in the large-scale Chinese cohort, which was further corroborated in the UK Biobank cohort. Mechanistically, we demonstrated that rs526835 enhances a promoterenhancer interaction mediated by the transcription factor JUN, leading to increased expression of FAM57A.Conclusions: We reveal the underlying mechanisms of CRC predisposition at the GWAS locus 17p13.3.Additionally, our findings highlight the critical role of FAM57A in CRC pathogenesis and introduce a novel enhancer-promoter interaction between FAM57A and rs526835, which could inform future precision prevention and personalized cancer therapies.

Effect of cardiac rehabilitation care after coronary intervention on cardiac function recovery and negative mood in patients with myocardial infarction

BACKGROUND Cardiovascular disease,particularly myocardial infarction(MI)profound impact on patients'quality of life and places a substantial burden on the healthcare and economy systems.Developments in medical technology have led to the emer-gence of coronary intervention as an essential method for treating MI.AIM To assess the effects of cardiac rehabilitation care on cardiac function recovery and negative emotions in MI after coronary intervention.METHODS This study included a total of 180 patients with MI during the period from June 2022 to July 2023.Selected patients were divided into two groups:An observation group,which receiving cardiac rehabilitation care;a control group,which re-ceiving conventional care.By comparing multiple observation indicators such as cardiac function indicators,blood pressure,exercise tolerance,occurrence of adverse cardiac events,and negative emotion scores between the two groups of patients.All the data were analyzed and compared between two groups.RESULTS There were 44 males and 46 females in the observation group with an average age of 36.26±9.88 yr;there were 43 males and 47 females in the control group,with an average age of 40.87±10.5 yr.After receiving the appropriate postoperative nursing measures,the results of the observation group showed significant improvement in several indicators compared with the control group.Indicators of cardiac function,such as left ventricular end-diastolic internal diameter and left ventricular ejection fraction were significantly better in the observation group than in the control group(P<0.05).Exercise endurance assessment showed that the 6-minute walking test distance was significantly increased in the patients of the observation group(P<0.01).In addition,the incidence of adverse cardiac events was significantly lower in the observation group,and negative mood scores were significantly reduced(P<0.05).CONCLUSION Cardiac rehabilitation care after coronary intervention has a significant positive impact on functional recovery.This emphasizes the importance of cardiac rehabilitation care to improve patient recovery.

Changes in Platelet GPIbα and ADAM17 during the Acute Stage of Atherosclerotic Ischemic Stroke among Chinese

Summary： Glycoprotein （GP） Ibα ectodomain shedding has important implications for thrombosis and hemostasis. A disintegrin and metalloproteinase 17 （ADAM17） was identified to play an essen- tial role in agonist induced GPIbαshedding. The relationship of GPIbu shedding and ADAM 17 in the acute stage of atherosclerotic ischemic stroke （AIS） patients has not been thoroughly studied. A total of 306 patients and 230 controls matched for age, sex, race, history of hypertension and diabetes mel- litus were enrolled in the study. GPIbα, ADAM17, glycocalicin were detected by flow cytometry, Western blotting, and enzyme-linked immunosorbent assay （ELISA） respectively. Compared with the control group, the expression of GPIbα in patients with acute ischemic stroke was significantly lower （P=0.000, P〈0.01）. Plasma glycocalicin and ADAM17 in AIS group were higher than those in con- trol group （P=0.699, P=0.000）. Pearson＇s analysis showed glycocalicin bore no correlation with GPIbu in AIS patients （r=0.095, P〉0.05）. GPIbα and National Institute of Health Stroke Scale （NIHSS） had negative correlation （r=-0.514, P〈0.01）. Our findings indicate that ADAM 17 may be a risk factor for ischemic stroke in Chinese and the expression of GPIbα can serve as a measure for stroke severity.

Efficacy and safety of transhepatic arterial chemoembolization with drug-loaded microspheres in unresectable primary liver cancer

BACKGROUND Transhepatic arterial chemoembolization(TACE),as a local treatment,has been widely used in the treatment of unresectable liver cancer.The introduction of drug carrier microspheres has brought new hope for the therapeutic effect of TACE.Microspheres can realize the slow release and directional delivery of drugs,reduce systemic toxicity and improve local curative effect.AIM To compare the effectiveness of traditional transcatheter arterial chemoembolization against microsphere-assisted transcatheter arterial chemoembolization in the treatment of hepatocellular carcinoma that is incurable.METHODS We searched the PubMed,Embase,Cochrane Library,and CNKI databases for clinical trials of drug-luting beads TACE(DEB-TACE)vs conventional TACE(cTACE)for the treatment of unresectable liver cancer.We screened references based on inclusion and exclusion criteria and then selected valid data for meta-analysis using RevMan 53 software.The complete response(CR)rate,partial response(PR)rate,postoperative stable disease(SD)rate,and 6-month and 12-month survival rates were compared.RESULTS A total of 12 articles were included,including 1177 patients,519 of whom received DEB-TACE and 658 of whom received cTACE.The CR rate in the DEB-TACE group was much greater than that in the cTACE group[relative risk(RR)=1.42,95%CI:1.18-1.72,P=0.0002].The 12-month survival rate significantly increased(RR=1.09;95%CI:1.01-1.17,P=0.03);the PR rate(RR=1.13;95%CI:0.97-1.30,P=0.12);the SD rate(RR=0.82;95%CI:0.64-1.05,P=0.12);and the 6-month survival rate(RR=1.05;95%CI:1.00-1.10,P=0.07).There was no significant difference(P<0.05).CONCLUSION Compared with those of iodized oil TACE,the drug-loaded microspheres tended to have therapeutic advantages.

Efficacy and Safety of Lianhua Qingke Tablets in the Treatment of Long Coronavirus Disease (COVID) Cough: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Clinical Study

Lianhua Qingke tablets,a patented traditional Chinese medicine that has validated clinical efficacy for treating cough caused by severe acute respiratory syndrome coronavirus 2 infection,lack rigorous evidence-based research evaluating their effect on long coronavirus disease(COVID)cough.A randomized,double-blind,placebo-controlled,multicenter clinical study was conducted among patients with long COVID cough from 19 hospitals and 23 community health centers in China.Patients were randomized 1:1 to receive either Lianhua Qingke tablets or placebo orally for 14 days(four tablets,1.84 g,three times a day).The primary endpoint indicator was the disappearance of cough,with the remission of cough also considered.Among 482 randomized patients,480(full analysis set 480;per-protocol set 470;safety set 480)were included in the primary analysis.According to the full analysis,the time until cough disappearance was significantly shorter in the trial group than in the control group,with a significant increase in the 14-day cough disappearance rate.Accordingly,the time to cough remission was significantly shorter in the trial group than in the control group.The change in the total symptom score was significantly greater in the trial group than in the control group on days 7 and 14,consistent with the results indicated by the visual analog scale(VAS)and cough evaluation test(CET)scores.No serious adverse events were recorded during the study.Lianhua Qingke tablets significantly improved the clinical symptoms of patients with long COVID cough.

Analysis of the Current Situation and Influencing Factors of Psychological Well-Being of Elderly People in the Community

Objective:To investigate the current psychological well-being of older people in the community and analyze its influencing factors.Methods:A total of 265 community-dwelling older adults aged 60 and above in Baoding City,Hebei Province,were selected through convenience sampling from November 2023 to March 2024.They were surveyed using a general information questionnaire and a comprehensive well-being questionnaire,with results analyzed statistically using SPSS 27.0.Results:Six dimensions of the psychological well-being scale for community older adults were identified:life vitality(P50=4.83),health concern(P50=4.6),self-worth(P50=5.6),friendly relationships(P50=5.33),altruistic behavior(P50=5.2),personality growth(P50=4.67),and comprehensive well-being(P50=161).Multivariate regression analysis showed that social isolation(β=-0.021,P<0.001),type of work(β=-0.142,P<0.001),chronic disease history(β=0.004,P<0.001),need for mobility aid(β=0.192,P<0.001),and monthly income(β=0.381,P<0.001)were factors influencing psychological well-being.Conclusion:The psychological well-being of the elderly is slightly above moderate and requires improvement.Enhancing factors such as reducing social isolation,addressing chronic disease history,and improving financial support could improve psychological well-being in older adults.

Pyogenic arthritis,pyoderma gangrenosum,and acne syndrome in a Chinese family:A case report and review of literature

BACKGROUND Pyogenic arthritis,pyoderma gangrenosum,and acne(PAPA)syndrome is a rare autosomal dominant genetic disease characterized by severe autoimmune inflammation,caused by mutations in the PSTPIP1 gene.Due to PAPA heterogeneous clinical manifestation,misdiagnosis or delayed diagnoses are difficult to avoid.With the use of whole-exome sequencing,we identified a missense mutation in the PSTPIP1 gene in a Chinese family.To the best of our knowledge,this is the first case of PAPA reported in China.CASE SUMMARY A 9-year-old boy suffered from recurrent aseptic pyogenic arthritis triggered by minor trauma or few obvious predisposing causes for more than 3 years.Pyogenic arthritis occurred every 3-5 mo,affecting his knees,elbows,and ankle joints.Treatments,such as glucocorticoids,antibiotics,even surgeries could alleviate joints pain and swelling to some extent but could not inhibit the recurrence of arthritis.Similar symptoms were present in his younger brother but not in his parents.According to the whole-exome sequencing,a missense mutation in exon 11 of the PSTPIP1 gene(c.748G>C;p.E250Q)was detected in the boy,his young-er brother and his father.Taking into account the similar phenotypic features with PAPA syndrome reported previously,we confirmed a diagnosis of PAPA syndrome for the family.CONCLUSION In this case,a missense mutation(c.748G>C;p.E250Q)in PSTPIP1 gene was identified in a Chinese family with PAPA syndrome.Previous studies emphasize the fact that PAPA syndrome is hard to diagnose just through the clinical manifestations owing to its heterogeneous expression.Genetic testing is an effectual auxiliary diagnostic method,especially in the early stages of pyogenic arthritis.Only if we have a deep understanding and rich experience of this rare disease can we make a prompt diagnosis,develop the best clinical treatment plan,and give good fertility guidance.

Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects

Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2<BMI<24 kg/m2),overweight(24 kg/m2≤BMI<28 kg/m2)and obese(BMI≥28 kg/m2)were 9.3%,59.9%,26.1%and 4.7%,respectively.A total of 18.3%(4,101/22,424)of patients had lost 5%or more of their bodyweight within the past month and 19.6%(2,463/12,538)of patients had lost 10%or more of their bodyweight within the past 6 months.According to the PG-SGA scores,26.6%of the patients were severely malnourished(score≥9),31.3%were moderately malnourished(scores 4~8).A total of 22.2%of patients had a serum albumin level lower than 35g/L.Only 8.6%(2056/23,991)of the patients had severe KPS scores(≤60).The patients with these severe KPS scores were most frequently among those with cancers of the brain(19.7%),prostate(18.0%),pancreas(15.5%)and bladder(15.0%).Based on the QLQ-C30 score,11.6%of patients had a poor QoL.The PG-SGA score and global QoL were correlated(r=-0.593,P<0.001).Conclusion The prevalence of malnutrition in patients with cancer is relatively high,and is related to a poorer QoL.The present findings should be kept in mind when assessing cancer patients,because addressing the patient’s problems in nutritional status would be expected to improve both the clinical outcomes and QoL in cancer patients with malnutrition.

Effect of notoginsenoside R1 on hepatic microcirculation disturbance induced by gut ischemia and reperfusion

AIM： To assess the effect of notoginsenoside R1 on hepatic microcirculatory disturbance induced by gut ischemia/reperfusion （I/R） in mice. METHODS： The superior mesenteric artery （SMA） of C57/BL mice was ligated for 15 min to induce gut ischemia followed by 30-rain reperfusion. In another set of experiments, R1 was continuously infused （10 mg/kg per hour） from 10 min before I/R until the end of the investigation to study the influence of R1 on hepatic microcirculatory disturbance induced by gut I/R. Hepatic microcirculation was observed by inverted microscopy, and the vascular diameter, red blood cell （RBC） velocity and sinusoid perfusion were estimated. Leukocyte rolling and adhesion were observed under a laser confocal microscope. Thirty and 60 min after reperfusion, lactate dehydrogenase （LDH）, alanine aminotransferase （ALl＇） and aspartate transaminase （AST） in peripheral blood were determined. The expression of adhesion molecules CD11b/CD18 in neutrophils and tumor necrosis factor- alpha （TNF-α）, interleukin-6 （IL-6） and monocyte chemotactic protein-1 （MCP-1） in plasma were evaluated by flow Oltometry. E-selectin and intercellular adhesion molecule-1 （ICAM-1） in hepatic tissue were examined by immunofluorescence.RESULTS： After gut I/R, the diameters of terminal portal venules and central veins, RBC velocity and the number of perfused sinusoids were decreased, while the leukocyte rolling and adhesion, the expression of E-selectin in hepatic vessels and CD18 in neutrophils, IL-6, MCP-1, LDH, ALT and AST were increased. R1 treatment attenuated these alterations except for IL-6 and MCP-1. CONCLUSION： R1 prevents I/R-induced hepatic microcirculation disturbance and hepatocyte injury, The effect of R1 is related to its inhibition of leukocyte rolling and adhesion by inhibiting the expression of E-selectin in endothelium and CD18 in neutrophils.

Effects of four regulating-intestine prescriptions on pathology and ultrastructure of colon tissue in rats with ulcerative colitis

AIM: To observe different histomorphologic changes of ulcerative colitis (UC) rats that were treated with four regulating-intestine prescriptions (FRIP), to investigate the curative effects of FRIP and to analyze their treatment mechanism.METHODS: The UC rat model was made by the method of 2,4-dinitro chloro benzene (DNCB) immunity and acetic acid local enema. Ninety-eight SD rats were randomly divided into seven groups, namely, the normal control group, model group, salicylazosulfapyridine (SASP) group,Wumeiwan (WMW) group, Baitouwengtang (BTWT) group,Senglingbaishusan (SLBSS) group, and Tongxieyaofang (TXYF) group. Each group had 14 rats (with equal ratio of male and female). The six animal model groups of UC-SASP, TXYF, WMW, BTWT, SLBSS, TXYF-were treated by distilled water except the normal control group. Changes of the rat's general conditions after treatment were respectively observed, the colon tissue damage scores were given out, the pathology of colonic mucosa and changes of ultrastructure were analyzed.RESULTS: Different pathological changes on histology were shown after treatment by FRIP. The colon tissue damage score in model group was higher than that of FRIP groups and SASP group (q = 4.59, 4.77, P＜0.05 or q = 5.48,6.25, 5.97, P＜0.01). The scores of WMW group, BTWT group and SLBSS group were lower than that of SASP (q = 4.13, P＜0.05 or q = 5.31, 5.12, P＜0.01). There was no remarkable difference between the damage score of TXYF group and SASP group (q = 3.75, P＞0.05). In addition, some apoptosis cells were found in the pathologic control group.CONCLUSION: The model made with DNCB and acetic acid was successful, and FRIP had better curative effect and WMW was the best curative effect, BTW, SLBSS and TXYF were similar to SASP, and we discovered that apoptosis was possibly related to UC.

Role of DOR-β-arrestin1-Bcl2 Signal Transduction Pathway and Intervention Effects of Oxymatrine in Ulcerative Colitis

This study was aimed to investigate the role of the delta-opioid receptor （DOR）-β-arrestinl-Bcl-2 signal transduction pathway in the pathogenesis of ulcerative colitis （UC） and the intervention effects of oxymatrine on UC. Forty Sprague-Dawley rats were divided into nor- mal group, model group, oxymatrine-treated group and mesalazine-treated group （n=10 each） at ran- dom. The rat UC model was established by intra-colonic injection of trinitrobenzene sulfonic acid in the model group and two treatment groups. The rats in oxymatrine-treated group were subjected to intramuscular injection of oxymatrine [63 mg/（kg·day）] for 15 days, and those in mesalazine-treated group given mesalazine solution [0.5 g/（kg·day）] by gastric lavage for the same days. Animals in normal group and model group were administered 3 mL water by gastric lavage for 15 days. On the 16th day, after fasting for 24 h, the rats were sacrificed for the removal of colon tissues. The expres- sion levels of DOR, β-arrestinl and Bcl-2 were determined in colon tissues by immunohistochemistry and real-time quantitative polymerase chain reaction （RT-PCR）, respectively. It was found that the expression levels of DOR, [3-arrestinl and Bcl-2 protein and mRNA were significantly increased in the model group as compared with the other groups （P〈0.05）. They were conspicuously decreased in both mesalazine-treated and oxymatrine-treated groups in contrast to the model group （P〈0.05）. No statistically significant difference was noted in these indices between mesalazine- and oxyma- trine-treated groups （P〉0.05）. This study indicated that the DOR-β-arrestinl-Bcl-2 signal transduc- tion pathway may participate in the pathogenesis of UC. Moreover, oxymatrine can attenuate the de- velopment of UC by regulating the DOR-β-arrestin 1-Bcl-2 signal transduction pathway.

Effect of Wumeiwan on Cytokines TNF-α,IL-6,IL-8,IL-10 and Expression of NF-κBp65 in Rats with Ulcerative Colitis

The effects of Wumeiwan （WMW） on TNF-α, IL-6, IL-8, IL-10 and NF-κBp65 in rats with ulcerative colitis （UC） were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine （SASP） was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley （SD） rats were randomly divided into four groups （n=14 in each group, with equal ratio of male and female）： normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene （DNCB） immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-α, IL-10 and the expression of NF-κBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-α were significantly increased （P〈0.01）, while those of IL-10 significantly reduced （P〈0.01） after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-α were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group （P〈0.05）. The levels of IL-6, IL-8, and TNF-α were lower, while the level oflL-10 was higher in WMW group than in SASP group. NF-κBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-κBp65 in WMW group and SASP group was obviously lower than in model group （P〈0.01）, and there was significant difference between WMW group and SASP group （P〈0.05）. It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-α, IL-6, IL-8, and inhibit the NF-κBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.

Eficacy of Electro-acupuncture in Treatment of Functional Constipation: A Randomized Controlled Trial

Functional constipation(FC)is a chronic discasc that significantly afcts the life quality of patients.Acupuncture has been used for the treatment of FC for many years,but its effectiveness has not been scientifcally assessed.The present study aimed to evaluate the efficacy of electro-acupuncture(EA)in relieving the symptoms,mental states and quality of life(QOL)of FC patients.A total of 96 FC patients were randomly allocated into EA,mosapride&sham EA group(MS)and mosapride control group(MC).In the EA group,patients were treated with 16 sessions of needling at Quchi(LI1I)and Shangjuxu(ST37)bilaterally,5 times a week in the first 2 weeks,and 3 times a.week in the last 2 weeks.In the MC group,patients were treated with 5 mg mosapride citrate three times a day for 4 weeks.In the MS group,patients underwent sham EA and the same mosapride citrate treatment as in the MC group.The primary outcome was the number of weekly spontaneous bowel movements(SBMs).The secondary outcomes included stool consistency,intensity of defecating difficulty,36-Item Short-Form Health Survey(SF-36),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS),and the validated Patient Assessment of Constipation-Quality of Life(PAC-QOL).The results showed that as compared with the baseline,EA significantly improved the weekly SBMs,stool consistency and intensity of defecating difficulty(P<0.05).It also partly ameliorated the PAC-QOL,SF-36,SDS and SAS scores when compared with MC or MS group(P<0.05).However,no significant difference was observed between MS and MC groups in bowel function outcomes and QOL scores.It was concluded that EA could effectivcly improve bowel function,mental states and QOL of FC patients.
