RESUMEN
To systematically review the effectiveness and safety of Tanreqing Injection in treating acute exacerbation of chronic bronchitis( AECB). CNKI,Wan Fang,VIP,CBM,Medline,Cochrane Library,EMbase and Web of Science were retrieved,and randomized controlled trials for the effect of Tanreqing Injection in the treatment of acute exacerbation of chronic bronchitis were screened. The quality of the included studies was evaluated according to the Cochrane Handbook's evaluation criteria. The data was analyzed by RevMan 5.3. Totally 23 RCTs involving 1 901 patients were included,including 952 in the experimental group and 949 in the control group. The Meta-analysis demonstrated that in terms of the disappearance time of fever,the group of Tanreqing Injection combined with the conventional therapy was superior to conventional therapy group( RR =-1. 03,95%CI[-1. 45,-0. 62],P<0. 000 01); compared with the conventional therapy group,the group of Tanreqing Injection combined with conventional therapy had a higher cure rate for AECB( RR = 1. 17,95% CI[1. 13,1. 23],P < 0. 000 01). The group of Tanreqing Injection combined with levofloxacin had a higher cure rate for AECB than the levofloxacin group( RR = 1. 23,95% CI[1. 08,1. 41],P = 0. 002). The group of Tanreqing Injection combined with cefuroxime had a higher cure rate for AECB than the cefuroxime group( RR = 1. 22,95%CI[1. 05,1. 42],P = 0. 01).The group of Tanreqing Injection combined with cefoperazone sodium and sulbactam sodium had a higher cure rate for AECB than the group of cefoperazone sodium and sulbactam sodium( RR = 1. 22,95% CI[1. 04,1. 44],P = 0. 02). The outcomes of disappearance time of cough and expectoration had a huge heterogeneity,so were used for descriptive analysis. The adverse reactions mainly included skin rash,dizziness,gastrointestinal reactions. Based on the available data and the results of the analysis,the group of Tanreqing Injection combined with Western medicine has a higher cure rate for acute exacerbation of chronic bronchitis,and the effect in reducing symptoms disappearance time. In view of the limited number of included studies,small sample size and low methodological quality,the results of this study need to be confirmed with high-level clinical trials.
