ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD. This article reviews the research advances in probiotics in the treatment of NAFLD, in order to provide a basis for the treatment of NAFLD using probiotics.
ABSTRACT
OBJECTIVE:To systematically review the efficacy of folic acid in the prevention of gastrointestinal(GI)tumors in elder,and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from Cochrane Library,PubMed,EM-Base,Web of Science,CMB,CJFD,VIP and Wanfang Database,the randomized controlled trials (RCT) about folic acid (test group)versus placebo(control group)in the prevention of GI tumors in elder(age>50 years old). After quality evaluation and da-ta extract,Meta-analysis was performed buy using Rev Man 5.3 statistics software. RESULTS:A total of 9 RCT were included,in-volving 29 494 patients. Results of Meta-analysis showed there was no significant difference in the incidence of GI tumors between 2 groups[RR=0.91,95%CI(0.74,1.12),P=0.38]. Results of subgroup analysis showed the incidence of GI tumors was not affected by GI tumor stage,age,basic serum folic acid level,type and dose of folic acid and follow-up time during follow-up period. CON-CLUSIONS:Folic acid supplement can not effectively prevent the incidence of GI tumors in elder. The incidence of GI tumors in elder with different ages and baseline of folic acid are not decreased by any dose and duration,without obvious adverse reactions. It indicates that folic acid supplement should be careful and give full conscideration to the patients’general situation. Due to the limit of methodological quality and sample size,it remains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.
ABSTRACT
Diabetic rat model accompanied by insulin resistance was established by intraperitoneal injection of streptozocin.Following metformin treatment for 5 weeks,ELISA was used to detect the level of plasma secreted frizzled-related protein (SFRP) 5,and immunohistochemistry was used to detect the expression of p-JNK in the liver.insulin resistance(IR) and p-JNK were significantly increased in diabetic group compared with the control group (P＜0.05),while plasma SFRP5 level was reduced (P＜0.01).After metformin treatment,the plasma SFRP5 levels were significantly increased (P＜0.05),while IR and p-JNK was decreased (P＜O.05).Metformin may ameliorate insulin resistance via upregulating the SFRP5 expression of diabetic rats.
ABSTRACT
Objective To study the perioperative predictors of portal vein thrombosis (PVT) after splenectomy in cirrhotic patients.Methods We searched the Web of Science,PubMed,EMBASE,Science Direct,CNKI,VIP,CSCD,and Wan Fang Databases up to April 2014.Only case-controlled studies which evaluated predictive factors of portal vein thrombosis (PVT) after splenectomy in cirrhotic patients were included.The Stata 12 software was used to perform the meta-analysis.Results Twenty-four casecontrolled studies were included.The sample size was 4 335,and the incidence rate of PVT was 25.0％.The risk factors of PVT included splenic volume (WMD =13.75,95％ CI:6.47 ～21.00),splenic vein diameter (WMD =1.34,95％ CI:0.39 ～ 2.30),portal vein diameter (WMD =1.54,95 ％ CI:0.56 ～ 2.52 ;WMD=2.09,95％CI:0.55 ～3.64),portal venous flow (WMD =-5.78,95％ CI:-10.46 ～-1.10;WMD =-5.57,95 ％ CI:-5.92 ～-5.22),difference in portal venous pressure (WMD =1.90,95 ％ CI:1.29～2.50) and ascites (OR =1.83,95％ CI:1.19,2.82).There were no significant differences between patients with and without PVT in terms of sex,age,Child-Pugh classification,prothrombin time,PLT,D-dimer,operating time.Conclusion The risk factors of portal vein thrombosis after splenectomy in cirrhotic patients were splenic volume,splenic vein diameter,portal vein diameter,portal venous flow,difference in portal venous pressure and ascites.
ABSTRACT
The present study was to investigate the analgesic effect and mechanism of meto-clopramide (MCP) on a rabbit visceral pain model. The results showed that MCP (8 mg? kg-1,iv) could produce a significant analgesic effect on visceral pain (P
