[Network Meta-analysis of efficacy and safety of Chinese patent medicines in treatment of insomnia].

To evaluate the efficacy and safety of Chinese patent medicines in the treatment of insomnia by frequency network Meta-analysis. Randomized controlled trials of Chinese patent medicines for insomnia were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library databases from the time of database establishment to October 2020. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 11 kinds of Chinese patent medicines in 27 RCTs were included. According to Meta-analysis, in term of the effective rate, Tianmeng Liquid, Zaoren Anshen Capsules, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Anshen Bunao Liquid and Qiye Anshen Tablets combined with nonbenzodiazepine drugs(NBZDs) were superior to NBZDs alone. In term of the improvement of Pittsburg sleeping quality index(PSQI) score, Tianmeng Liquid, Shumian Capsules, Shensong Yangxin Capsules, Bailemian Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Yangxue Qingnao Granules and Yindan Xinnaotong Capsules combined with NBZDs were superior to NBZDs alone. In terms of the safety, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets and Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. In terms of the avoidance of dizziness and headache, Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. The results of Network Meta-analysis indicated that in term of the effective rate, top three optimal medication regimens were NBZDs combined with Shugan Jieyu Capsules, combined with Zaoren Anshen Capsules and combined with Shensong Yangxin Capsules in the order from high to low. With the respect of improvement of PSQI score, top three optimal medication regimens were NBZDs combined with Yangxue Qingnao Granules, combined with Tianmeng Liquid and combined with Yindan Xinnaotong Capsules in the order from high to low. In terms of the safety, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Shensong Yangxin Capsules and combined with Shenqi Wuweizi Tablets in the order from high to low. In terms of the avoidance of dizziness and headache, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Zaoren Anshen Capsules and combined with Shumian Capsules in the order from high to low. In terms of the avoidance of fatigue, top three optimal medication regimens were NBZDs combined with Shensong Yangxin Capsules, combined with Shumian Capsules and combined with Qiye Anshen Tablets in the order from high to low. In conclusion, Chinese patent medicines combined with NBZDs can effectively alleviate the symptoms of insomnia with a high safety. However, the conclusion of this study needs to be verified by more high-quality studies because of the low methodological quality of the included studies.

Fumanjian, a Classic Chinese Herbal Formula, Can Ameliorate the Impairment of Spatial Learning and Memory through Apoptotic Signaling Pathway in the Hippocampus of Rats with Aß 1-40 -Induced Alzheimer's Disease.

Alzheimer's disease (AD) is the most common form of dementia and lacks disease-altering treatments. Fumanjian (FMJ), a famous classic Chinese herbal prescription for dementia, was first recorded in the Complete Works of Jingyue during the Ming Dynasty. This study aimed to investigate whether FMJ could prevent cognitive deficit and take neuroprotective effects in Aß 1-40-induced rat model through apoptotic signaling pathway. AD model was established by bilateral injection of Aß 1-40 into hippocampus in rat. All rats were tested for their capabilities of spatial navigation and memorization by Morris water maze. Apoptosis was tested using TUNEL staining in hippocampus neuronal cells; RT-PCR tested expression of Bcl-2 and Bax mRNA; western blotting tested protein level of cleaved caspase-3. After 14 days of treatment, FMJ significantly improved the escape latency and enhanced platform-cross number compared with the Aß 1-40-injected group (P < 0.05 or P < 0.01). FMJ also significantly decreased number of TUNEL-positive neuronal apoptosis and the expressions of Bax and cleaved Caspase-3 and increased the expression of Bcl-2 (P < 0.01) compared with AD model group. In conclusion, FMJ exerts a protective effect against Aß 1-40-induced learning and memory deficits and neuronal apoptosis, suggesting that FMJ could be used as a potential therapeutic formula for AD.

[Study on protective effect of cerebrospinal fluid containing Qingxin Kaiqiao Fang on sodium dithionite-induced PC12 cell injury].

OBJECTIVE: To study the protective effect of cerebrospinal fluid containing Qingxin Kaiqiao Fang on sodium dithionite (Na2S2O4)-induced PC12 cell injury, in order to provide basis for clinical application of the prescription. METHOD: SD rats were orally administered with water decoction of Qingxin Kaiqiao Fang (7. 9 g . kg-1) once every 12 h, for a total of 7 times, in order to prepare cerebrospinal fluid containing Qingxin Kaiqiao Fang. The neurocyte injury model was established by adding Na2S2O4 with the final concentration of 8 m mol . L-1 into PC12 cells. With nimodipine (1 x 10(7)mol . L-1 ) as the positive control group, MTT method test was adopted to detect the impact of cerebrospinal fluid containing Qingxin Kaiqiao Fang on the activity of PC12 cells. The expression of Bax, Bel-2 and Caspase-3 mRNA was detected by RT-PCR. RESULT: The cerebrospinal fluid containing Qingxin Kaiqiao Fang groups showed a significantly higher activity in PC12 cells than the model group, with decrease in expressions of Bax mRNA and Caspase-3 mRNA and increase in expression of Bel-2 mRNA. There were significant differences compared with the model group (P< 0. 05,P <0. 01). CONCLUSION: Qingxin Kaiqiao Fang shows a notable protective effect on Na2S2 04-induced neurocyte injury.
