Dan'e-fukang soft extract for dysmenorrhea: a meta-analysis / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To assess the efficacy and safety of Dan'e-fukang soft extract for dysmenorrhea by meta-analysis.</p><p><b>METHODS</b>Cochrane Controlled Trials Register, PubMed, EMBASE, CBM, VIP, Wanfang Data, and CNKI databases were searched. Results of randomized controlled trials were also harvested from pharmaceutical companies by manual search. Meta-analysis was carried out according to the method provided by the Cochrane Collaboration with RevMan5.0 software.</p><p><b>RESULTS</b>Twelve Chinese papers were selected, and 1213 patients were included. Significant difference in recovery rate was found between Dan'e-fukang soft extract group and other drugs group (RR=1.33, 95%CI: 1.02-1.75, P<0.05), but the difference no longer existed when studies with pseudo ginseng and marvelon were removed from other drug groups (RR=1.08, 95%CI: 0.91-1.29, P>0.05). No statistical difference was noticed in total effective rate between two groups (RR=1.04, 95%CI: 1.00-1.08, P>0.05). A statistical difference in improvement of dysmenorrhea symptoms was found before and after treatment in both Dan'e-fukang soft extract group and other drugs group (MD=5.79, 95%CI: 5.01-6.56, P<0.001; MD=4.62, 95%CI: 3.71-5.53, P<0.001), while no significant difference was seen between two groups before treatment (MD=0.20, 95%CI: -0.11-0.50, P>0.05) and after treatment (MD=-0.94, 95%CI: -2.11-0.23, P>0.05). Oral administration of Dan'e-fukang soft extract caused only mild gastrointestinal discomfort, but other drugs had more adverse effects including serious gastrointestinal reaction, severe liver dysfunction, vaginal bleeding, and female masculinity.</p><p><b>CONCLUSION</b>The existing evidence shows that Dan'e-fukang soft extract has the same efficacy as other drugs in treatment of dysmenorrheal. Because of the quality of the included studies was limited, the evidence of the efficacy and safety of Dan'e-fukang soft extract was not strong, and high-quality randomized trials with large samples are needed.</p>

Effects of di'ao xinxuekang soft capsule on lipid peroxidation and the endothelial function in patients with coronary heart disease / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effects of Di' ao Xinxuekang Soft Capsule (DK) on the plasma levels of superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO), and endothelin (ET) in patients with coronary heart disease (CHD), and to study its underlying mechanisms.</p><p><b>METHODS</b>Totally 100 patients with CHD confirmed by coronary angiography were randomly assigned to two groups, the control group (60 cases) and the DK treatment group (40 cases). Patients in the control group received conventional therapy, while those in the DK treatment group received DK additionally. The therapeutic course for all was 3 months. The plasma levels of SOD, MDA, ET, and NO were determined pre-treatment, 4, 8, and 12 weeks after treatment.</p><p><b>RESULTS</b>Compared with before treatment, the serum levels of SOD and NO increased and the levels of MDA and ET decreased at each time point. Besides, better effects were obtained in the DK treatment group (P < 0.05).</p><p><b>CONCLUSION</b>DK possibly played a role in inhibiting lipid peroxidation and improving the endothelial dysfunction.</p>
