Abstract:To systematically evaluate the efficacy of traditional Chinese medicine in the treatment of chronic radioactive enteritis.Methods:Cochrane Central,PubMed,EM-BASE,Chinese Biomedical Literature Database (CBM),Chinese Journal Full-text Database (CNKI),Weipu Chinese Science and Technology Journal Full-text Database (VIP),Wanfang Data Knowledge Service Platform (WANFANG DATA) were retrieved by computer and were used to collect a randomized controlled clinical trial of TCM for chronic radiation enteritis.After 2 researchers independently screened the literature,extracted data and evaluated the risk of bias included in the study,and Rev Man5.3 software was used for Meta analysis.Results:A total of 207 papers were selected,According to the literature,excluding 189 papers,18 clinical studies and 1 427 patients were adopted.Among these,there were 724 cases in the test group,and 703 in the control group.Meta analysis results:clinically effective rate of patients in the test group [RR=1.31,95%CI(1.25~1.39),P<0.000 01] higher than the control group,rate of intestinal mucosal injury in experimental group [RR=1.33,95%CI(1.08~1.65),P=0.008] higher than the control group.The remission rate of mucosal injury under colonoscopy in the test group [RR=1.33,95%CI(1.08~1.65),P=0.008] was higher than that of the control group.The test group was able to reduce pro-inflammatory factors,improve immune function,and shorten treatment time,and is better than the control group,and the difference is statistically significant (P<0.05).Traditional Chinese medicine group was better than the Western medicine group in improving the quality of life,and the difference was statistically significant (P<0.05).Conclusion:Based on the current research,Chinese medicine can effectively relieve abdominal pain,diarrhea,blood stool,fatigue and other related symptoms in patients with chronic radiation enteritis.It can effectively promote the healing of the intestinal mucosa.However,the current treatment schemes have large differences and the number of research documents is small.There is no uniform standard for TCM schemes.Therefore,higher quality research is still needed to confirm the treatment of TCM.The therapeutic effect of the disease,so as to provide evidence-based medicine for clinical evidence.a.
