Efficacy and safety of Shumian capsules in treating insomnia: A systematic review and meta-analysis.
It is known to all that the incidence of insomnia is becoming higher and higher with the increase of people's life stress. To some extent, it has brought about bad effects on people's life, work, study, and health, such as mental exhaustion, low work efficiency, and mood irritability. Now there are medications and non-medications methods for insomnia. As one of the treatments for insomnia, western medicine is to prolong the sleeping time and improve the anxious mood. However, taking western medicine to treat insomnia can also be accompanied by some adverse reactions at the same time, such as drug dependence, an allergic reaction, and so on. Traditional Chinese medicine therapy is based on syndrome differentiation and holistic concept. Shumian capsules (SM) are a kind of proprietary Chinese medicine for insomnia, which have the effect of relieving depression and calming the mind. But there are no studies on the efficacy and safety of SM in the treatment of insomnia. Therefore, I will provide a systematic review and meta-analysis to evaluate the efficacy and safety of SM for insomnia.
All the studies searched were from PubMed, EMBASE, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, and WanFang databases, and the studies types included in the analysis were all randomized controlled trials. All the retrieval contents were completed independently by 2 researchers, and a third reviewer would be involved when there existed any disagreement. The eligible studies were screened out according to the inclusion criteria and exclusion criteria, and some useful information was extracted and made into a feature table, including the year of the included studies, the age, and disease course of the participants in the studies and intervention methods, etc. Cochrane risk-of-bias tool was used to evaluate the quality of literature and meta-analysis was conducted by RevMan 5.4 software.
A total of 9 articles including 709 participants were included in the study after screening out. The primary outcomes of statistical analysis were cure rate and total effective rate, while the secondary outcomes included Pittsburgh sleep quality index score and incidence of adverse reactions. The results showed that Pittsburgh sleep quality index score of the SM group and Western medicine group were statistically significant (MD = -0.50, 95% confidence interval [CI] = [-0.78, -0.22], P = .0005). The total effective rate of the SM group was slightly higher than that of the Western medicine group, but there was no statistical significance (relative risk [RR] = 1.03, 95% CI = [0.95,1.13], P = .43).
This meta-analysis provides evidence for the efficacy and safety of SM in the treatment of insomnia, and provides a new idea for the clinical treatment of insomnia. But more research is needed to support further evidence.

Zao Ren An Shen for insomnia: a systematic review with meta-analysis.
To assess the effectiveness and safety of Zao Ren An Shen (ZRAS), a Chinese herbal medicine formula, for the treatment of insomnia.
Seven databases (ie, EMBASE, PubMed, the Cochrane library, and PsycINFO, Chinese National Knowledge Infrastructure, Wanfang and Chongqing VIP) were searched from their inception to 6 November 2018. Controlled trials comparing the effectiveness or safety of ZRAS to conventional treatments, a placebo or no-treatment in an insomnia population were selected. Primary outcomes were: sleep quality (assessed with the Pittsburgh Sleep Quality Index, PSQI), and the number of adverse events at post-treatment. The risk of bias was assessed with the Cochrane Collaboration's tool and meta-analyses were performed using RevMan 5.3.
A total of 19 studies (1780 participants) were included. The effect of ZRAS on sleep quality (mean difference) was found to be superior compared to placebo in the sole placebo-controlled study located [-0.90 (-1.56, -0.24; 95% CI), p = 0.007] and similar to Benzodiazepine Receptor Agonists (BzRAs) [0.17 (-0.29, 0.64); 95% CI, p = 0.46]. The number of adverse events (relative risk) was lower for ZRAS than BzRAs [0.16 (0.12, 0.23; 95% CI), p < 0.001]. An overall high risk of bias was found in the selected studies.
The results favor ZRAS against BzRAs and placebo for the treatment of insomnia. However, the poor methodology of the studies prevents strong recommendations for ZRAS. Clinical trials with higher quality designs are required.
