Objective:We carried out a meta-analysis to assess the effectiveness and safety of radiotherapy combined with surgery for gastric cancer.Methods:Randomized Clinical Trials (RCTs) in which radiotherapy (preoperative,intraoperative and postoperative),was compared with surgery alone in resectable gastric cancer were identified by searching Cochrane Library (Issue 2,2009),PubMed (Jan 1966-Jun 2009),EMBASE (Jan 1974-Jun 2009),Chinese Biomedical Literature Database (Jan 1978-Jun 2009),Chinese Science and Technology Periodicals Database (Jan 1989-Jun 2009),China National Knowledge Infrastructure (Jan 1994-Jun 2009) and Wanfang database (Jan 1997-Jun 2009) in English and Chinese languang.Two researchers assessed the quality of included randomized controlled trials (RCT) extracted data independently.The RevMan 5.0 software was used for meta-analysis.Our researchers assessed the quality of included randomized controlled trials (RCT) extracted data independently.The RevMan 5.0 software was used for meta-analysis.Results:Nine randomized controlled trials of 1 548 patients were selected for meta-analysis.Five randomized controlled trials were related with comparison of preoperative radiotherapy plus surgery with single surgery.Two randomized controlled trials were the comparative studies between surgery plus postoperative and single surgery.The meta-analysis results showed that:(1) compared with surgery alone,preoperative radiotherapy combined with surgery can increase 3 years (OR=1.78;95% CI 1.14-2.78,P=0.01),5 years (OR=1.67;95% CI 1.22-2.29,P=0.001),10 years (OR=1.64;95% CI 1.03-2.60,P=0.04) survival rate and resection rate (OR=2.15;95% CI 1.31-3.54,P=0.003);reduce the of tumor recurrence rate (OR=0.59;95% CI 0.37-0.92,P=0.02) and metastasis rate (OR=0.44;95% CI 0.27-0.73,P=0.001);(2) The tumor recurrent rates (OR=0.19,95% CI 0.03-1.14,P=0.07) and tumor metastasis rate (OR=0.09;95% CI 0.00-1.77,P=0.11) had no difference between single surgery group and peri-operative radiotherapy plus surgery group;(3) Postoperative radiotherapy compared with surgery alone had no significant effects on 1 year (OR=0.83;95% CI 0.60-1.15,P=0.26) and 3 years (OR=0.75;95% CI 0.51-1.11,P=0.15) survival rate compared with single surgery,but the 5-year survival rates (OR=0.57;95% CI 0.34-0.95,P=0.03) of the patients who received surgery alone was higher than those who received combined therapy.No difference of the tumor recurrence rate (OR=0.59;95% CI 0.33-1.05,P=0.07),tumor metestasis rate (OR=0.90;95% CI 0.51-1.59,P=0.71) and anastomotic leak (OR=0.98;95% CI 0.25-3.65,P=0.98) were observed between the two groups.Conclusion:Preoperative radiotherapy combined surgery is more rational and effective than surgery alone of gastric cancer.However,in terms of the clinical effects of perioperarive or postoperative radoiotherapy combined with surgery,much multicenter,largescale,high-quality,double-blind and rigorously designed studies would be needed than currently available in the future. 展开更多

OBJECTIVE: To evaluate the efficacy of Banxiaxiexin Tang compared with Western Medicine in the treatment of functional dyspepsia(FD) through Meta-analysis.METHODS: Literature was searched in the following databases: MEDLINE, Excerpta Medica Database, Chinese Medical Current Contents, China Science and Technology Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure. Randomized controlled trials evaluating the efficacy of Banxiaxiexin Tang for the treatment of FD were selected according to certain standards including clear general situation of patients, specific diagnostic criteria, definite clinical outcomes, etc. Articles were evaluated with quality assessment standards in the Cochrane Handbook for Systematic Reviews of Interventions. Meta-analysis was conducted with RevMan 5.0.23 software.RESULTS: Ten articles with a total of 972 patients were included. The comparison of efficacy between Banxiaxiexin Tang and Western Medicine showed a combined effect size [OR=2.75, 95% CI(1.86-4.07)]andcombinedeffectofvalueofZ=5.07(P<0.000 01),suggesting a significant difference between the groups.CONCLUSION: Banxiaxiexin Tang was more effective thanWestern Medicine in treating FD. 展开更多

OBJECTIVE: To compare the efficacy of integrated Chinese and Western Medicine with that of only Western Medicine for the treatment of malignant ascites.METHODS: All randomized controlled trials(January 2004 to March 2013) from the China National Knowledge Infrastructure Database, Chinese Biomedical Literature Database, and Wanfang Database were searched with keywords. Meta-analysis was conducted by combining the odds ratios of the individual studies. Review Manager 5.0 was used for the analysis.RESULTS: One thousand one hundred and fifty-six patients from 19 randomized controlled trails were included. Of them, 630 patients were treated with integrated Chinese and Western Medicine(the integrative group), and 526 patients were treated with Western Medicine alone(the control group). The Meta-analysis showed that the total effective rate was 78.73% in the integrated group, and 59.13% in the control group. The effective percentage was sig-nificantly higher in the integrative group than that of the control group [OR = 2.85, 95% CI(2.16,3.74),P < 0.01].CONCLUSION: The short-term curative effect in the integrative group was better than that in the control group. Integrative medicine may be beneficial for malignant ascites. 展开更多

OBJECTIVE: To assess the effectiveness and safety of acupuncture therapy for angina pectoris. METHODS: Randomized controlled trials (RCTs) concerned with acupuncture treatment of angina pectoris were identified by searching Academic Source Premier, MEDLINE, Science Citation Index Expanded, and three Chinese databases (China biol- ogy medicine database, China national knowledge infrastructure, and VlP database for Chinese techni- cal periodicals). The valid data were extracted in ac- cordance with our inclusion and exclusion criteria. The main outcomes of the included studies were synthesized using Revman 5.1. RESULTS: Twenty-one articles on 16 individual studies were included and evaluated as having high or moderate risk of bias according to the stan- dards of the Cochrane Collaboration. Meta-analysis indicated that acupuncture combined with conven- tional drugs (ACCD) was superior to conventional drugs alone in reducing the incidence of acute myocardial infarction (AMI) [0R=0.18, 95%CI (0.04,0.84), P=0.03]. Moreover, ACCD was superior to con- ventional drugs in the relief of angina symptoms [0R=4.23, 95%C/(2.73, 6..56), P〈0.00001], and im- provement of electrocardiography (ECG) [0R=2.61, 95%C/(1.83, 3.73), P〈0.00001]. Acupuncture by it- self was also superior to conventional drugs for angi- na symptoms [0R=3.59, 95%C/(1.76, 7.92), P=0.0004] and ECG improvement [0R=3.07, 95%C/(1.54, 6.10), P=0.001]. ACCD was superior to conventional drugs in shortening the time to onset of angina relief [WMD=-1.40, 95% CI (-1.65, -1.15), P〈 0.00001]. However, the time to onset was signifi- cantly longer for acupuncture treatment than for conventional treatment alone [WMD=2A3, 95%O (1.63, 3.23), P〈0.000 01]. CONCLUSION: ACCD reduced the occurrence of AMI, and both acupuncture and ACCD relieved an- gina symptoms and improved ECG. However, com- pared with conventional treatment, acupuncture showed a longer delay before its onset of action. This indicates that acupuncture is not suitable for emergency treatment of heart attack. Owing to the poor quality of the current evidence, the findings of this systematic review need to be verified by more RCTs to enhance statistical power. 展开更多

OBJECTIVE: To assess the efficacy of Huangshukuihua(Flos Abelmoschi Manihot) on diabetic nephropathy(DN).METHODS: Articles were retrieved from Pub Med,EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure Database, Chinese Evidence-Based Medicine Database, and Wanfang Database. Two reviewers independently reviewed the article. Only randomized controlled trials were included and 27 were identified involving 2239 patients(1143 in the treatment group and 1096 in the control group).RESULTS: Huangshukuihua(Flos Abelmoschi Manihot) had a significant effect on renal function by improving blood urea nitrogen and serum creatinine,reducing urine protein(24-h urine protein, and urinary albumin excretion rate), and improving serum albumin level, compared with the control group.CONCLUSION: Our findings suggest that, although the bioactive ingredients and mechanism underlying renal protection are unknown, the role of Huangshukuihua(Flos Abelmoschi Manihot) in the treatment of DN deserves further investigation. 展开更多
