Objevtive To investigate the efficacy of Xuebijing injection combined with Ulinastatin for acute pancreatitis.Methods Databases were searched,like Pubmed,Embase,Cochrane Central Register of Controlled Trials (CENTRAL),China Biology Medicine disc (CBM),China National Knowledge Infrastructure (CNKI),Cochrane library,and Wangfang for randomized controlled trial (RCT) about the treatment of Xuebijing injection combined with Ulinastatin for acute pancreatitis.After evaluating the quality of literatures objectively,data were analyzed by RevMan 5.0 software.we evaluated abdominal pain relief time,recovery time of blood amylase,recovery time of white blood cell (WBC),concentration of interleukin (IL)-6,IL-8,tumor necrosis factor α (TNF-o) and total effective rate.Results Eleven studies and 893 patients were accepted into this article.Meta-analysis showed that abdominal pain relief time [weighted mean difference (WMD) =-1.71,95 ％ CI:-2.21,-1.21,P ＜ 0.01],recovery time of blood amylase (WMD =-1.82,95 ％ CI:-2.39,-1.25,P ＜ 0.01),recovery time of WBC (WMD =-2.75,95 ％ CI:-3.19,-2.31,P ＜ 0.01),and hospital stay time (WMD =-5.99,95 ％ CI:-7.73,-4.26,P ＜ 0.01)in experimental group was better than control group.Compared to control group,on the seventh day after treatment,inflammatory cytokines,including IL-6 [standardized mean difference (SMD) =-1.09,95％ CI:-2.66,0.48,P=0.17],IL-8 (SMD=-1.02,95％ CI:-1.66,-0.38,P＜0.01),andTNF-α (SMD =-1.10,95％ CI:-1.68,-0.53,P ＜ 0.01) were lower.In experimemal group,total effective rate was better than the control group (RR =1.16,95％ CI:1.07,1.25,P=0.0002).Conclusions Xuebijing injection combined with Ulinastatin for acute pancreatitis was more effective than traditional basal treatment or using Ulinastatin alone.However,the literature quality were mediocre,we need more large,random,double blind,and polycentric clinical study to prove further.

ObjectiveTo investigate the effects of artemisinin （ART） on histopathological damage and salivary secretion in the submandibular gland （SMG） of mice with Sjögren's syndrome （SS） model，and on the expression of aquaporin 5 （AQP5） in SMG cells. MethodsThe NOD/Ltj mice were used as a model of SS and randomly divided into the SS model group，the ART group，and the hydroxychloroquine sulfate （HCQ） group，with six mice per group. Another 6 female BALB/c mice at the same week were selected as the control group. Mice in the ART group was fed with the ART solution daily in the dosage of 50 mg·kg^-1，and mice in the HCQ group was given with the HCQ solution （1 300 mg·kg^-1）. Mice in the SS model and control groups were given saline daily. The treatment lasted for 8 weeks. The 24-hour average water intake，salivary flow rate，SMG pathology scores of mice in each group were measured，as well as the expression levels of AQP5 protein and gene in the SMG tissues. ResultsCompared with the control group，the 24-hour average water intake of mice in the model group was significantly increased （P<0.01），and the saliva flow rate was significantly decreased （P<0.01）. Compared to the SS model group，the 24-hour average water intake of mice in the ART and HCQ groups was significantly reduced （P<0.01），and the salivary flow rate was significantly increased in the ART group（P<0.01），comparisons between groups showed that the ART was superior to the HCQ in reducing water intake and improving saliva flow rate in SS model mice （P<0.05）. The HE staining results showed that，compared with the normal group，the number of lymphocyte infiltration foci in SMG tissue in the model group increased，and the pathological score increased （P<0.01）. Compared to the SS model group，after the intervention of the ART and HCQ，the number of lymphocytic infiltration foci in the SMG tissue decreased，the area of the lymphocytic infiltration foci was reduced，and the pathology score of the SMG tissues was lowered in the ART group（P<0.01）. However，there was no difference in pathological scores between the ART and HCQ groups . The results of IHC，Western blot，and Real-time PCR showed that，compared with the normal group，the expression levels of AQP5 protein and gene in SMG tissue in the model group significantly decreased （P<0.05）. Comparing with the SS model group，the ART and HCQ groups could significantly up-regulated the expression levels of AQP5 protein and mRNA in the SMG tissue，and the treatment effect was better than that of HCQ. ConclusionART was able to ameliorate SMG structural damage and salivary secretion function in SS model mice，and its mechanism of action may be related to the up-regulation of AQP5 protein and gene expression levels in SMG cells.
