Effect of Yinqi Ointment on Wound Morphology and Growth Factor in Treating Diabetic Foot Ulcer

Objective: To investigate the effect of Yinqi ointment on wound morphology and growth factor in treating diabetic foot ulcer(DFU).Methods: From December 2016 to December 2017, 92 cases of DFU with deficiency of both Qi and Yin syndrome were randomly divided into treatment group and control group(44 cases in each group). The treatment group was treated with Yinqi ointment, while the control group was treated with mupirocin ointment. After 4 weeks of treatment, the ulcer healing effect, ulcer area, granulation tissue, epithelial tissue coverage,pain score, and dynamic analysis of vascular endothelial growth factor(VEGF), epidermis growth factor(EGF), and basic fibroblast growth factor(bFGF) in local granulation tissue were statistically analyzed before and after treatment in both groups. Results: The total effective rate was 88.37% in the treatment group and 74.42% in the control group. The wound reduction rate, epithelial tissue coverage rate, granulation tissue growth rate, and local pain relief rate in the treatment group were significantly superior to those in the control group(P 0.05). Through the local granulation detection, the treatment group and the control group have increased VEGF, EGF, and bFGF, but the treatment group increased the role of growth factor than the control group. Conclusion: Yinqi ointment can promote the healing of DFU, and its mechanism may be related to the increase of the content of growth factor in granulation tissue.     

Effects of the Clearing the Lung and Dissipating Phlegm Method in the Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis

Objective: The objective of this study is to evaluate the efficacy and safety of the clearing the lung and dissipating phlegm method in the treatment of acute exacerbation of chronic obstructive pulmonary disease(COPD) and to provide evidence for the treatment of the disease. Materials and Methods: Literature was searched from the United States National Library of Medicine(PubMed), Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database(Wanfang), and the Full?Text Database of Chinese Scientific and Technical Periodicals(VIP).A comprehensive collection was made of randomized controlled trials(RCTs) before June 2018, in which the treatment groups used either the clearing the lung and dissipating phlegm formulas only or combined it with routine Western medicine therapy, and the control group adopted routine Western medicine therapy only for the acute exacerbation of COPD. The Cochrane risk of bias method was used to evaluate the quality of the literature. The data were analyzed and retrieved independently by two reviewers before meta?analysis was carried out with RevMan 5.3 software to evaluate the primary outcome measures, including the total clinical effective rate, and the secondary outcome measures such as the pulmonary function(forced vital capacity [FVC], forced expiratory volume in the 1 s [FEV1], percentage of FEV1 [FEV1%], and FEV1/FVC)and blood gases(PaO_2 and PaCo_2). Results: A total of 13 RCTs involving 990 patients(496 in the treatment group and 494 in the control group)were included in this study. Meta?analysis revealed significant difference in the efficacy of the group that adopted solely the routine Western medicine method and the group that combined the Western medicine with the clearing the lung and dissipating phlegm method. Outcome measures including the pulmonary function(FVC, FEV1, FEV1%, and FEV1/FVC) and the blood gases(PaO_2 and PaCo_2) were significantly improved as compared to the control group(P 0.00001). However, adverse effects in the treatment group using combined traditional Chinese medicine were not reported due to the short observation time of the study. Conclusion: The clearing the lung and dissipating phlegm method can improve the efficacy in the treatment of acute exacerbation of COPD, the outcome measures of the pulmonary function and the blood gases,as well as the life quality of the patients. However, due to the fact that the existing studies are generally of poor quality in which randomization and its implementation were not properly carried out, more high?quality RCTs are necessary to confirm the findings of this study.

发作性睡病的药物治疗进展

发作性睡病是致残性白天睡眠增多的最常见原因之一，其治疗旨在减少白天睡眠增多和猝倒，改善夜间睡眠紊乱、睡眠瘫痪及与睡眠有关的幻觉。2019年，组胺H3受体拮抗剂替洛利生（Pitolisant）和多巴胺及去甲肾上腺素再摄取抑制剂索利氨酯（Solriamfetol）分别在欧盟和美国上市，前者具有促醒和抗猝倒作用，后者也有促醒作用，且戒断症状和滥用的发生率更低。目前，控释型羟丁酸钠（FT218）、低钠型羟丁酸盐（JZP-258）、选择性去甲肾上腺素再摄取抑制剂（瑞波西汀，又称AXS-12）以及莫达非尼联合氟卡尼制剂（THN102）等药物仍在开发和测试中，均可作为治疗发作性睡病相关白天睡眠增多和猝倒的潜在药物。本文重点介绍这些最近研发的发作性睡病治疗药物。     

我国茯苓炮制加工和产品研发现状与展望

茯苓是我国大宗中药原料,也是卫生部批准的药食两用中药资源。趁鲜蒸制加工已基本取代"发汗"工艺,成为茯苓主流的初加工技术。茯苓经不同方法炮制得到有白茯苓、赤茯苓、茯苓皮、炒茯苓和朱茯苓,其功效各有侧重。茯苓在古代经典名方中应用广泛,现代已形成桂枝茯苓丸等主打中成药产品。国家中医药管理局公布的《古代经典名方目录(第一批)》100首方剂中,以茯苓为主要原料的经典名方占到了24%。以茯苓为原料的保健食品多达776个,主要保健功能为免疫调节、缓解体力疲劳和改善睡眠。茯苓的应用已经形成了涉及普通食品、化妆品、中兽药和饲料添加剂的综合开发体系。加强质量控制、规范化炮制生产和功效突出的产品研发将是茯苓产业发展的趋势。
