ObjectiveTo evaluate pharmacological effects of Shengmai injection（SMI）on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free （SPF） Sprague-Dawley （SD） rats were randomly divided into a sham group， a model group， a low-dose SMI group（3 mL·kg^-1）， a middle-dose SMI group（6 mL·kg^-1）， a high-dose SMI group（12 mL·kg^-1）， and a Ginaton group（4 mL·kg^-1）according to the random number table method， with 12 rats in each group. The rat model of cerebral ischemia-reperfusion（MCAO/R）was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion， which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores， cerebral infarction area， hematoxylin-eosin （HE） staining， Nissl staining， terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） staining， and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay （ELISA）， Western blot， and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation（OGD/R）-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group， the model group showed significantly increased neurological function scores， cerebral infarction area， neuronal apoptosis rate， and expression levels of apoptosis related proteins （P<0.05， P<0.01）and significantly decreased density of Nissl bodies and neurons（P<0.01）. Compared with the model group， the SMI groups exhibited significantly decreased neurological function scores， cerebral infarction area， neuronal apoptosis rate， and expression levels of apoptosis related proteins （P<0.05， P<0.01）and significantly increased density of Nissl bodies and neurons （P<0.05）. The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury， and the chloride intracellular channel protein 1 （CLIC1） was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced， compared with those in the model group（P<0.05， P<0.01）， and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 （NLRP3） decreased （P<0.01）. In addition， the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate（P<0.01） and significantly decreased the intracellular chloride ion concentration（P<0.05）. ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

Objectives:To investigate the effect of non-optimal temperature exposure during pregnancy on the risk for preterm birth and identify the susceptible exposure window. At the same time, the interaction between non-optimal temperature and pollutants exposure during pregnancy on preterm birth was analyzed, in order to provide strong clues for the influence of non-optimal temperature exposure during pregnancy on the risk for preterm birth.Methods:A total of 1 852 pregnant women were recruited from September 2021 to June 2023 in Fujian Provincial Maternal and Child Health Care Center. Questionnaire survey was conducted, and their health records were analyzed. The permanent address of each pregnant woman was matched with Fifth Generation European Centre for Medium-Range Weather Forecasts Atmospheric Reanalysis of the Global Climate and a geo-statistical combination model based on satellite remote sensing data collection, then follow-up for pregnancy outcome was conducted. Distributed lag nonlinear model was used to assess the association between exposure to non-optimal temperature during pregnancy and the risk for preterm birth and a multiplicative interaction model was used to assess the interaction between exposure to pollutants and non-optimal temperatures during pregnancy on the risk for preterm birth.Results:After adjusting for potential confounders such as maternal age, occupation, Gross Domestic Product of the region, pre-pregnancy preconception BMI, newborn sex, the weekly susceptibility windows of extreme low temperature ( P1, P3, P5) were week 1-22 , and the weekly susceptibility windows of extreme high temperature ( P95, P97, P99) were week 27 and week 32-36. Extreme low temperature [ P1 ( OR=1.147, 95% CI: 1.041-1.265), P5 ( OR=1.284, 95% CI: 1.035-1.501)] and extreme high temperature [ P97 ( OR=1.146, 95% CI: 1.039-1.263), P99 ( OR=1.216, 95% CI: 1.099-1.345)] exhibited multiplicative interaction with PM 2.5. Conclusions:Exposure to non-optimal temperature during pregnancy was associated with an increased risk for preterm birth. The susceptible exposure windows of extreme low temperature were mainly in early and mid-pregnancy, and the susceptible exposure windows of extreme high temperature were mainly in late-pregnancy. Exposure to non-optimal temperatures and pollutants during pregnancy was associated with an increased risk for preterm birth.

Objective To explore the perioperative safety and prognostic factors of sequential hepatectomy after conversion therapy using vascular interventional therapy(including transarterial chemoembolization and hepatic arterial infusion chemotherapy)combined with tyrosine kinase inhibitors(TKI)and programmed death-1(PD-1)inhibitors in patients with initially unresectable hepatocellular carcinoma.Methods The clinical data of 106 eligible HCC patients treated in Tumor Hospital Affiliated to Guangxi Medical University from Nov.2019 to Apr.2024 were retrospectively analyzed.The perioperative parameters and postoperative pathological outcomes were described in detail,and factors influencing prognosis were analyzed.Results The median operative time for hepatectomy after conversion therapy was 240 min,with a median blood loss of 200 mL.Intraoperative blood transfusion was required in 24(22.6％)patients.Postoperative adverse reactions occurred in 49.1％(52/106)of patients,with liver failure being the most common adverse reactions(23 patients,21.7％).One(0.9％)patient died during the perioperative period,while the remaining 105 patients were followed up for a median duration of 14.7 months,during which 49(46.2％)patients experienced recurrence.Among them,39(36.8％)cases experienced early recurrence(within 1 year),and 33(31.1％)cases had intrahepatic recurrence.Thirteen(12.3％)patients died during follow-up.The median recurrence-free survival(RFS)was 15.7 months,with 1-year and 2-year RFS rates being 56.9％and 40.3％,respectively.The median overall survival(OS)was not reached,with 1-year and 2-year OS rates being 94.2％and 85.3％,respectively.Multivariate Cox regression analysis demonstrated that achieving complete pathological response(hazard ratio[HR]=0.410,95％confidence interval[CI]0.172-0.980,P=0.045),presence of microvascular invasion(HR=2.423,95％CI 1.269-4.625,P=0.007),satellite nodules(HR=1.916,95％CI 1.014-3.620,P=0.045),and multiple tumors(HR=1.818,95％CI 1.012-3.241,P=0.046)were independent factors associated with postoperative recurrence.Conclusion For patients with initially unresectable hepatocellular carcinoma,vascular interventional therapy combined with TKI and PD-1 inhibitors followed by sequential hepatectomy may be a feasible treatment strategy,with manageable adverse reactions and promising efficacy.

OBJECTIVE To evaluate the efficacy,safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB).METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People's Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024.Patients were divided into imported original drug group(original drug group,221 cases)and centrally procured generic drug group(generic drug group,75 cases)according to the types of drug used.Propensity score matching(PSM)was performed at a ratio of 3∶1 to compare the clinical efficacy,safety and economics between the two groups.RESULTS Totally 241 patients were included after PSM,with 170 in the original drug group and 71 in the generic drug group.There were no significant differences between the two groups in terms of rebleeding rate,rate of second endoscopic intervention,blood transfusion rate,length of hospital stay,mortality due to gastrointestinal bleeding,30-day readmission due to rebleeding,and overall survival rate(P＞0.05).The incidence of adverse events among all patients in both groups also showed no statistically significant difference(P＞0.05);furthermore,the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups.After PSM,the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group,while the median nursing fee and bed fee were significantly higher than those in the original drug group(P＜0.05).There was no statistically significant difference between the two groups in terms of median total hospitalization expenses,total treatment costs,laboratory fees,examination fees,material costs,or consultation fees(P＞0.05).CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug,and it is more economical.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2％dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2％ DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.
