[Systematic review and Meta-analysis of efficacy and safety of Ningmitai Capsules in treatment of urinary tract infection].

This study aims to evaluate the effectiveness and safety of Ningmitai Capsules in the treatment of urinary tract infection.To be specific, articles on the treatment of urinary tract infection with Ningmitai Capsules were retrieved from China National Know-ledge Infrastructure(CNKI), Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, and Web of Science(from establishment to October 2021).Eligible randomized controlled trials(RCTs) were screened out, and ROB and RevMan 5.3 of Cochrane were employed for data integration and Meta-analysis.Finally, 17 articles were included, involving 1 972 cases, with 1 045 in the experimental group and 927 in the control group.The Meta-analysis results are as follows.Ningmitai Capsules combined with conventional antibiotics was superior to sensitive antibiotics alone in the treatment of acute pyelonephritis in aspects of clinical cure rate(RR=1.94, 95%CI[1.58, 2.37], P<0.000 01), reduction in the count of red blood cells in the urine(MD=-3.22, 95%CI[-3.23,-3.21], P<0.000 01), decrease in the count of white blood cells in the urine(MD=-2.34, 95%CI[-2.59,-2.10], P<0.000 01), and time for the disappearance of the symptoms(MD_(time for urinary tract irritation disappeared)=-2.19, 95%CI[-2.69,-1.68], P<0.000 01; MD_(time for waist aches disappeared)=-3.58, 95%CI[-4.20,-2.97], P<0.000 01; MD_(time for heating disappeared)=-0.57, 95%CI[-0.81,-0.33], P<0.000 01).The combination of either cephalosporin or quinolone with Ningmitai Capsules can improve clinical cure rate of acute pyelonephritis(RR_(combined with cephalosporin)=1.94, 95%CI[1.56, 2.42], P<0.000 01; RR_(combined with quinolone)=1.91, 95%CI[1.16, 3.15], P=0.01).The clinical cure rate(RR=1.91, 95%CI[1.47, 2.49], P<0.000 01) of diabetes complicated with urinary tract infection by Ningmitai Capsules was higher than that by quinolones.The clinical cure rate(RR=1.22, 95%CI[1.09, 1.37], P=0.000 5) of non-gonococcal urethritis by Ningmitai Capsules combined with conventional tetracycline and macrolide antibiotics was higher than that by conventional antibiotics.Ningmitai Capsules combined with conventional antibiotics/Ningmitai Capsules alone was superior to conventional antibiotics alone in the treatment of urinary tract infection in terms of the clinical cure rate(RR=1.35, 95%CI[1.17, 1.56], P<0.000 1) and incidence of adverse reactions(RR=0.32, 95%CI[0.15, 0.68], P=0.003), particularly the combination with quinolone antibiotics(RR=1.30, 95%CI[1.04, 1.61], P=0.02).The main adverse reactions were mild gastrointestinal discomfort, nausea, vomiting, and dry mouth.In summary, Ningmitai Capsules combined with conventional sensitive antibiotics/Ningmitai Capsules alone can improve the clinical cure rate of patients with urinary tract infection.Ningmitai Capsules combined with conventional sensitive antibiotics can significantly reduce the time for symptom disappearance of acute pyelonephritis and down-regulate the counts of red and white blood cells in the urine compared with antibiotics alone, and no serious adverse reactions have been found.However, in light of the low proportion of quality eligible articles, experiments with rigorous design, large sample size, and complete outcome in-dexes should be carried out in the future to verify the clinical efficacy and safety of Ningmitai Capsules in the treatment of urinary tract infection.

[Treating influenza patients of wind-heat affecting Fei syndrome by jinhua qinggan granule: a double-blinded randomized control trial].

OBJECTIVE: To assess the effect and safety of Jinhua Qinggan Granule (JHG) in treating influenza patients of wind-heat affecting Fei syndrome (WHAFS). METHODS: Totally 136 influenza patients of WHAFS were randomized by stratification into 3 groups, the high dose JHG group (44 cases, 10 g each time), the low dose JHG group (45 cases, 5 g JHG + 5 g placebo each time), and the placebo control group (47 cases, 10 g placebo each time). All medication was administered three times daily for 5 days. The fever disappearance time, the fever disappearance rate, efficacy of TCM syndrome, the disappearance rate of main symptoms and physical signs of flu, the negative rate of virus nucleic acid in the pharyngeal secretion, and safety indicators were assessed. RESULTS: The median fever disappearance time was 32.8 h (95% CI: 22.5-41.0 h) in the high dose JHG group, 26.0 h (95% CI: 14.5-36.5 h) in the low dose JHG group, 39.5 h (95% CI: 29.0-46.0 h) in the placebo control group. There was statistical difference in the median fever disappearance time between the low dose JHG group and the placebo control group (P = 0.011). Three days after treatment, the markedly effective rate of TCM symptoms in the low dose JHG group was 66.7%, higher than that of the placebo control group (38.3%), and its effective rate was superior to that of the high dose JHG group (P = 0.043). Five days after treatment, the recovery rate of the low dose JHG group (42.2%) was higher than that of the high dose JHG group (25.0%, P = 0.026) and that of the placebo control group (14.9%, P = 0.002). The markedly effective rate of the low dose JHG group (86.7%) was higher than that of the placebo control group (55.3%, P = 0.001). Similar effects were obtained in the low dose JHG group and the high dose JHG group, but slightly poor in partial indicators of the high dose JHG group. There was no statistical difference in adverse reaction among these three groups (P > 0.05). CONCLUSIONS: JHG was effective and safe in treating influenza patients of WHAFS. Routinely low dose was the optimal dosage of JHG.
