Pharmacological Mechanism of Curcumae Radix in Treatment of Post-stroke Depression： A Review / 中国实验方剂学杂志

Post-stroke depression， a common mental complication after stroke， seriously affects the quality of life and even endangers the life safety of patients. It is difficult to be cured due to the complex and diverse pathogenesis. At present， the widely accepted pathogenesis mechanisms include inflammatory mechanism， neurotransmitter mechanism， and endocrine mechanism. According to the theory of Chinese medicine， Qi stagnation， blood stasis， and phlegm turbidity lead to the occurrence of mental diseases after stroke. Curcumae Radix， as a commonly used Chinese herbal medicine， can activate blood circulation for relieving pain， regulate Qi， and relieve depression. The summary of the medication rules of DENG Tie-tao， ZHANG Xue-wen and other Chinese medical physicians showcases that Curcumae Radix is frequently used in the clinical treatment of depression， stroke， and post-stroke depression. Modern pharmacological studies have demonstrated that Curcumae Radix contains β-sitosterol， curdione， curcumin and other medicinal ingredients. This study reviewed the pharmacological effects of effective components in Curcumae Radix and the pharmacological mechanism in the treatment of post-stroke depression and summarized the processing methods of Curcumae Radix， aiming to clarify the important role and determine the optimal processing method of Curcumae Radix in the treatment of post-stroke depression. The results indicate that Curcumae Radix has the effects of regulating neurotransmitters， inhibiting neuroinflammation， protecting neurons， regulating neuroendocrine and antithrombosis， which can prevent and treat post-stroke depression through multiple components， targets， and pathways. The wine-processed Curcuma longa has the best effect.

Systematic review and Meta-analysis of efficacy and safety of Toutongning Capsules in treatment of tension-type headache / 中国中药杂志

This study aims to systematically evaluate the clinical efficacy and safety of Toutongning Capsules in the treatment of tension-type headache(TTH), so as to provide a corresponding basis for clinical treatment. Eight commonly used medical research databases and two clinical trial registration systems were retrieved with the time interval from the establishment of the database or system to November 2020. The randomized controlled trials of Toutongning Capsules in the treatment of TTH were screened out according to the pre-set criteria. The quality of the included papers was evaluated by the bias risk assessment tool in Cochrane Reviewers Handbook 6.1 and the data were statistically analyzed by RevMan v5.4 provided by Cochrane collaboration. A total of 13 studies were included and the quality of methodology was generally low. Meta-analysis showed that Toutongning Capsules assisted with western medicine therapy can effectively reduce the pain intensity(MD_(VAS)=-1.94,95%CI[-2.50,-1.38],P<0.000 01;MD_(NRS)=-0.83,95%CI[-0.86,-0.80],P<0.000 01), headache duration(SMD=-0.98,95%CI[-1.17,-0.79],P<0.000 01), headache frequency(MD=-1.01,95%CI[-1.16,-0.85],P<0.000 01), headache index(MD=-11.13,95%CI[-12.10,-10.16],P<0.000 01), anxiety and depression scale score(MD_(HAMA)=-4.02,95%CI[-6.58,-1.46],P=0.002;MD_(HAMD)=-2.67,95%CI[-4.04,-1.29],P=0.000 1), while Toutongning Capsules as monotherapy only reduced the headache score(MD=-2.24,95%CI[-2.97,-1.51],P<0.000 01). The available clinical studies demonstrate that Toutongning Capsules combined with western medicine in the treatment of TTH can improve the related outcome indicators, but the clinical safety and efficacy of Toutongning Capsules alone remain unclear. Due to the small number and low quality of the included studies, large-sample, multi-center, high-quality and strictly designed randomized controlled trials are still needed to verify the clinical efficacy in the future.

Effect of Naoshuantong capsule on change of SSQOL index in patients with ischemic stroke in six mouths follow-up / 中国中药杂志

To evaluate the effect of Naoshuantong capsule on the life quality of patients with ischemic stroke in six months of follow-up studies, and observe the adverse events. The results would provide reference for the secondary prevention on the recovery stage of ischemic stroke. 696 patients from 12 Class III Grade I hospitals nationwide were divided into 2 groups by central randomization system. The study group, 344 cases, were treated with Naoshuantong capsule plus Aspirin, and the control group, 352 cases, were treated with Aspirin. The patients were treated for 6 months. At the end of treatment, SS-QOL used for evaluating the quality of life was observed. The safety index was defined by adverse observation event. The incidence of adverse events and laboratory tests results were observed before and after treatment at the same time. The results indicated that compared to the control group, the treatment group had significant statistical difference in the impact of effort, self-care ability and the the work or labor ability of patients (P < 0.05). No serious adverse events were observed. Naoshuantong capsule showed some superiority to Asprin on improving the quality of life on patients with ischemic stroke, and it could be used in secondary prevention on the recovery stage of ischemic stroke. Naoshuantong capsule is safe and effective in the treatment of convalescence ischemic stroke.
