The rats were intraperitoneally injected with 50 mg/kg of paraquat. One hour after paraquat administration, the rats were treated intravenously with Xuebijing(8 mL /kg). At 12 hours after paraquat administration, serum was collected to evaluate kidney function, then the rats were sacrificed and kidney samples were immediately harvested. AKI scores were evaluated by renal histopathology and pro-in? ammatory cytokines mR NA levels in kidney were assayed using real-time RT-PCR.RESULTS: Serum urea nitrogen, creatinine and AKI scores were significantly higher in the paraquat group, compared with the sham group(P<0.05, respectively). Moreover, interleukin(IL)-1β, IL-6 and TNF-α m RNA levels were signi? cantly higher in the paraquat group(P<0.01, respectively). However, intravenous Xuebijing signi? cantly decreased serum urea nitrogen, creatinine, AKI scores and IL-1β, IL-6 and TNF-α m RNA levels, compared with the paraquat group(P<0.05, respectively).CONCLUSION: Intravenous Xuebijing attenuates AKI following paraquat poisoning by suppressing in? ammatory response.展开更多

文摘Circulating tumor cells(CTCs)are neoplastic cells that are detached from primary tumors and enter circulation.Enumeration and characterization of CTCs are of significance in cancer diagnosis,prognosis,and treatment monitoring.CTC survival in the bloodstream is a limiting step for the development of metastases in distant organs.Recent technological advances,especially in single-cell molecular analyses have uncovered heterogeneous CTC survival mechanisms.Undergoing epithelial-to-mesenchymal transition(EMT),increasing stem cell-like properties,and forming cell clusters enable CTCs to adapt to the harsh microenvironment of the circulation.Expressing and releasing several immunosuppressive molecules help CTCs escape from anti-cancer immune mechanisms.This review article summarizes the biological characteristics of CTCs and focuses on the recent understanding of the mechanisms by which CTCs survive in circulation.Additionally,the clinical and therapeutic implications of CTCs are discussed.
文摘BACKGROUND Acute cerebral infarction(ACI)is characterized by a high incidence of morbidity,disability,recurrence,death and heavy economic burden,and has become a disease of concern in global researchers.As ACI has serious effects on patients’physical status,life and economy,often causing anxiety,depression and other psychological problems,these problems can lead to the aggravation of physical symptoms;thus,it is very important to understand the factors affecting the mental health of these patients.AIM To understand the elements that affect the mental health of patients who have suffered an ACI.METHODS A questionnaire survey was conducted among patients with ACI admitted to three tertiary hospitals(Quanzhou First Hospital,Fuqing City Hospital Affiliated to Fujian Medical University,and the 900 Hospital of the Joint Service Support Force of the People’s Liberation Army of China)in Fujian Province from January 2022 to December 2022 using the convenience sampling method.ACI inpatients who met the inclusion criteria were selected.Informed consent was obtained from the patients before the investigation,and a face-to-face questionnaire survey was conducted using a unified scale.The questionnaire included a general situation questionnaire,Zung’s self-rating depression scale and Zung’s self-rating anxiety scale.All questionnaires were checked by two researchers and then the data were input and sorted using Excel software.The general situation of patients with ACI was analyzed by descriptive statistics,the influence of variables on mental health by the independent sample t test and variance analysis,and the influencing factors on psychological distress were analyzed by multiple stepwise regression.RESULTS The average age of the 220 patients with ACI was 68.64±10.74 years,including 142 males and 78 females.Most of the patients were between 60 and 74 years old,the majority had high school or technical secondary school education,most lived with their spouse,and most lived in cities.The majority of patients had a personal income of 3001 to 5000 RMB yuan per month.The new rural cooperative medical insurance system had the largest number of participants.Most stroke patients were cared for by their spouses and of these patients,52.3%had previously smoked.Univariate analysis showed that gender,age,residence,course of disease,number of previous chronic diseases and smoking history were the main factors affecting the anxiety scores of patients with ACI.Age,living conditions,monthly income,course of disease and knowledge of disease were the primary variables influencing the depression score in patients with ACI.The findings of multivariate analysis revealed that the course of disease and gender were the most important factors influencing patients’anxiety scores,and the course of disease was also the most important factor influencing patients’depression scores.CONCLUSION Long disease course and female patients with ACI were more likely to have psychological problems such as a high incidence of emotional disorders.These groups require more attention and counseling.

文摘BACKGROUND Myocardial infarction is one of the most common types of coronary heart disease.It is mainly caused by the rupture of coronary atherosclerotic plaque,which leads to platelet agglutination and thrombosis.The occlusion of coronary arteries and vessels leads to insufficient myocardial blood supply,subsequently causing cardiac interstitial fibrosis,gradual enlargement of ventricles,and heart failure,which affects the quality of life and safety of patients.AIM To investigate the effects of emergency percutaneous interventional therapy(PCI)and delayed stenting in acute myocardial infarction with high thrombotic load and identify factors related to major adverse cardiovascular events(MACE).METHODS A total of 164 patients with acute myocardial infarction and high thrombotic load who received PCI were included.Of them,92 patients were treated with delayed stent implantation(delayed group)and 72 patients received emergency PCI(immediate group).Myocardial perfusion after stent implantation was compared between the two groups.Patients were followed up for 12 mo,and the occurrence of MACE was used as the endpoint.Univariate and multivariate models were used to analyze the factors affecting MACE occurrence.RESULTS After stent implantation,66(71.74%)patients in the delayed group and 40(55.56%)patients in the immediate group had thrombolysis in myocardial infarction(TIMI)flow grade 3(P<0.05),while 61(66.30%)patients in the delayed group and 39(54.17%)patients in the immediate group reached TIMI myocardial perfusion grade 3(P>0.05).MACE occurred in 29 patients.There were statistically significant differences between the MACE and non-MACE groups in diabetes rate,TIMI grading,stent implantation timing,intraoperative use of tirofiban,and the levels of white blood cells(WBC),neutrophils,red blood cell distribution width(RDW),and uric acid,and high-sensitivity C-reactive protein(hs-CRP)at admission(P<0.05).Logistic regression analysis showed that TIMI grade 3 and intraoperative use of tirofiban effectively reduced the risk of MACE(P<0.05),while immediate stent implantation,increased WBC,hs-CRP and RDW on admission increased the risk of MACE(P<0.05).CONCLUSION Delayed stent implantation outweighs emergency PCI in improving postoperative myocardial perfusion in acute myocardial infarction with high thrombotic load,and effectively reduces MACE in these patients.
文摘BACKGROUND: The study aimed to investigate the therapeutic benefits of intravenous Xuebijing on acute kidney injury(AKI) in rats with paraquat intoxication.METHODS: Male Sprague-Dawley rats were randomly divided equally into three groups: sham group(n=8), paraquat group(n=8) and Xuebijing-treated group(n=8) using a random number table. The rats were intraperitoneally injected with 50 mg/kg of paraquat. One hour after paraquat administration, the rats were treated intravenously with Xuebijing(8 mL /kg). At 12 hours after paraquat administration, serum was collected to evaluate kidney function, then the rats were sacrificed and kidney samples were immediately harvested. AKI scores were evaluated by renal histopathology and pro-in? ammatory cytokines mR NA levels in kidney were assayed using real-time RT-PCR.RESULTS: Serum urea nitrogen, creatinine and AKI scores were significantly higher in the paraquat group, compared with the sham group(P<0.05, respectively). Moreover, interleukin(IL)-1β, IL-6 and TNF-α m RNA levels were signi? cantly higher in the paraquat group(P<0.01, respectively). However, intravenous Xuebijing signi? cantly decreased serum urea nitrogen, creatinine, AKI scores and IL-1β, IL-6 and TNF-α m RNA levels, compared with the paraquat group(P<0.05, respectively).CONCLUSION: Intravenous Xuebijing attenuates AKI following paraquat poisoning by suppressing in? ammatory response.

文摘Background and Aims:Hepatitis B is a vaccine-preventable liver infection caused by the hepatitis B virus(HBV),and is seen as a serious global health problem.HBV infection induces the expression of type I interferon(IFN),including IFN-αand IFN-β,which have anti-HBV activities,and have been used for HBV treatment.IL2-inducible T-cell kinase(ITK)is a tyrosine kinase,which regulates T-cell differentiation and activation,while its precise effects on type I IFN production during HBV infection remain unknown.Methods:We monitored the ITK expression in peripheral blood mononuclear cells(PBMCs)from healthy donors and patients with acute and chronic HBV infection.We used ITK inhibitor ibrutinib to treat hepatocytes and evaluated the type I IFN expression after HBV infection.We also administrated ibrutinib to mice and evaluated its effect on HBV infection in vivo.We generated ITK,suppressor of cytokine signaling 1(SOCS1)knockout and ITK/SOCS1 double knockout cells using CRISPR,and monitored the HBV-induced type I IFN production.Results:ITK and type I IFN were upregulated in patients with acute HBV infection.Inhibition of ITK by ibrutinib suppressed HBVinduced expression of type I IFN mRNA in mice.ITK knockout cells had decreased IRF3 activation but promoted the expression of SOCS1.ITK negatively regulated SOSC1 expression.The down regulation of type I IFN in ITK knockout cells after HBV stimulation was abolished in the absence of SOCS1.Conclusions:ITK regulated HBV-induced expression of type I IFN mRNA by modulating SOCS1.
文摘Objective:To investigate the effect of internal heat acupuncture on the tolerance time of plantar hot plate and the pain threshold of gastrocnemius in rats with chronic myofascial pain syndrome(MPS).Methods:A total of 80 adult Wistar rats were randomly selected to establish chronic MPS rat models,and randomly divided into four groups:control group,acupuncture group,internal heat acupuncture group A,and internal heat acupuncture group B,with 20 rats in each group.The rats in the control group were not given any treatment,and the rats in the acupuncture group were only given acupuncture treatment.The rats in group A were treated with internal heat acupuncture(needle heating up to 42℃),and the rats in group B were treated with internal heat acupuncture(needle heating up to 44℃).The tolerance time of plantar hot plate,the pain threshold of gastrocnemius muscle and the level of tumor necrosis factor-α(TNF-α)were observed and compared before modeling,1 d before treatment,and 1,7 and 14 d after treatment.Results:There were significant differences in hot plate tolerance time,time and interaction among the four groups(P<0.05),as well as in gastrocnemius tenderness threshold,time and interaction among the four groups(P<0.05),and there were also significant differences in TNF-αlevel among the three groups(P>0.05).There were significant differences in the number of electric shocks,time and interaction among the four groups(P<0.05).Conclusion:In contrast to conventional acupuncture treatment,internal heat acupuncture demonstrates greater efficacy in extending the tolerance duration of hot plate exposure and enhancing the pain threshold of the gastrocnemius muscle in rats afflicted with myofascial pain syndrome.Additionally,it accelerates the amelioration of inflammatory markers and motor function.However,it is important to note that the therapeutic impact of internal heat acupuncture may be influenced by its temperature,with 44℃being the most effective in this research.

文摘The glymphatic system plays a pivotal role in maintaining cerebral homeostasis.Chronic cerebral hypoperfusion,arising from small vessel disease or carotid stenosis,results in cerebrometabolic disturbances ultimately manifesting in white matter injury and cognitive dysfunction.However,whether the glymphatic system serves as a potential therapeutic target for white matter injury and cognitive decline during hypoperfusion remains unknown.Here,we established a mouse model of chronic cerebral hypoperfusion via bilateral common carotid artery stenosis.We found that the hypoperfusion model was associated with significant white matter injury and initial cognitive impairment in conjunction with impaired glym・phatic system function.The glymphatic dysfunction was associated with altered cerebral perfusion and loss of aquaporin 4 polarization.Treatment of digoxin rescued changes in glymphatic transport,white matter structure,and cognitive function.Suppression of glymphatic functions by treatment with the AQP4 inhibitor TGN-020 abolished this protective effect of digoxin from hypoperfusion injury.Our research yields new insight into the relationship between hemodynamics,glymphatic transport,white matter injury,and cognitive changes after chronic cerebral hypoperfusion.

文摘Effective coverage and protection is a priority in wound treatment.Collagen and chitosan have been widely used for wound dressings due to their excellent biological activity and biocompatibility.Silver nanoparticles(AgNPs)have a powerful antibacterial effect.In this study,a macromolecular and small-molecular collagen mixed solution,a macromolecular and small-molecular chitosan mixed solution were prepared,and a silver nanoparticle-loaded collagen-chitosan dressing(AgNPCCD)has been proposed.First,the effects of a collagen-chitosan mixed solution on the proliferation of human umbilical vein endothelial cells and the secretion of cytokines were evaluated.Then,the characteristics and antibacterial effects of the AgNP-CCD were tested,and the effects on wound healing and the influence of wound cytokine expression were investigated via a deep second-degree burn wound model.The results showed that at the proper proportion and concentration,the collagen-chitosan mixed solution effectively promoted cell proliferation and regulated the levels of growth factors(vascular endothelial growth factor[VEGF],epidermal growth factor[EGF],plateletderived growth factor[PDGF],transforming growth factor[TGF-b1],basic fibroblastic growth factor[bFGF])and inflammatory factors(TNF-α,IL-1β,IL-6,IL-8).Moreover,AgNP solutions at lower concentrations exerted limited inhibitory effects on cell proliferation and had no effect on cytokine secretion.The AgNP-CCD demonstrated satisfactory morphological and physical properties as well as efficient antibacterial activities.An in vivo evaluation indicated that AgNP-CCD could accelerate the healing process of deep second-degree burn wounds and played an important role in the regulation of growth and inflammatory factors,including VEGF,EGFL-7,TGF-β1,bFGF,TNF-α and IL-1β.This AgNP-CCD exerted excellent biological effects on wound healing promotion and cytokine expression regulation.
文摘To the Editor:In sepsis,bacterial endotoxins play a central role by inducing a dysregulated and exaggerated release of inflammatory mediators and cytokines,often described as the“cytokine storm”or“cytokinemia.”[1]Both endotoxins and cytokines have been implicated in the development of organ dysfunction,including acute kidney injury(AKI).[2]Removing circulating endotoxins and excess cytokines from the circulation restores chemotactic gradients,localizing the immune response to the principal site of infection and re-establishing a regulated immune response.[1,3]Therefore,using hemofilters with enhanced endotoxin and cytokine adsorptive properties may bring about additional therapeutic benefits compared with conventional continuous renal replacement therapy(CRRT)filters.
