本草类书籍与《滇南本草》历代药图演变评述*

本草学是东方医药学的重要标志。在生境中辨识药用植物是本草学的重点，本草著作在对药用植物进行描述的同时，基于知识传授的实际需要，会配以药图帮助学者掌握该药材的特点以方便识别。药图在发展过程中逐渐从本草著作的附属成为独立的册页，其科学和艺术价值也日益凸显，然而其重要性并没有被太多研究者重视，尤其将药图研究的视野从传统医药扩展至文化史、艺术史、美学和文化资源学等领域的研究成果更是鲜有。本文从本草学和本草图谱的演变发展历史为线索，以云南地域本草的杠鼎之作《滇南本草》各时期版本中代表性药图作为研究对象，对比《本草纲目》等几种代表性本草著作中的药图，结合文化和艺术史相关知识，初步梳理《滇南本草》各历史时期药图的特点，分析其演变原因和具体社会条件，尝试从历史角度理解和归纳这些不同时期和版本药图的发展变化呈现的特点并揭示我们今天研究和利用中国传统药图这一重要文化资源的意义和价值。     

中药药浴治疗痉挛型脑性瘫痪患儿的临床效果

左卡尼汀联合重组人促红素注射液治疗规律透析慢性肾功能衰竭合并贫血患者的临床效果

目的探究左卡尼汀联合重组人促红素注射液治疗规律透析慢性肾功能衰竭合并贫血患者的临床效果。方法选择2017年1月至2020年1月收治的100例规律透析慢性肾功能衰竭合并贫血患者,以计算机随机化法将其分为对照组和试验组,每组50例。对照组给予重组人促红素注射液治疗,试验组给予左卡尼汀与重组人促红素注射液联合治疗。比较两组患者的治疗效果。结果试验组的治疗总有效率为96.00%,高于对照组的80.00%(P<0.05);治疗后,两组患者的MCHC、MCH、MCV、SF、Hb、RBC水平均高于治疗前,且试验组高于对照组(P<0.05);两组患者的不良反应总发生率比较,差异无统计学意义(P>0.05)。结论规律透析慢性肾功能衰竭合并贫血患者接受左卡尼汀与重组人促红素注射液联合治疗,可获得较好的效果,改善贫血相关生化指标水平,且不良反应发生率低,安全有效。     

Chinese herbal injections combined with rt-PA intravenous thrombolysis for acute ischemic stroke: A systematic review and meta-analysis protocol

Background:Acute ischemic stroke (AIS) is an important factor leading to adult death and disability globally. For AIS patients who meet certain conditions, recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis is an important method recommended by national guidelines to achieve vascular recanalization. However, complications such as hemorrhagic transformation and vascular reocclusion after thrombolysis are still unsolved problems in clinical. Several systematic reviews of clinical randomized controlled trials (RCTs) in the past have shown that Chinese herbal injections (CHIs) can improve the neurological function of patients, increase the tolerance of ischemic tissues to hypoxia, and inhibit platelet aggregation. Therefore, this study conducted a meta-analysis of AIS treatment with intravenous thrombolysis alone and compared it with the combined application of CHIs. To evaluate whether CHIs have a synergistic effect on thrombolytic therapy and provide a basis for clinical application.Methods:The following databases will be searched until September 2020: ①English databases: PubMed, Cochrane Library, Embase; ②Chinese databases: CNKI, Wanfang database, Weipu database, SinoMed. RCTs will be included to compare the efficacy of thrombolysis combined with CHIs and thrombolysis alone in the treatment of AIS. Data extraction and risk of bias assessments will be carried out by 2 verifiers independently. The risk of bias will be evaluated through the Cochrane risk of bias tool. Review Manager software 5.3 will be used for statistical analysis.Results:This study will provide comprehensive evidence for the treatment of AIS by CHIs combined with intravenous thrombolysis from multiple aspects.Conclusion:The conclusion of the meta-analysis will provide a basis for judging whether CHIs combined with intravenous thrombolysis is an effective measure for the treatment of AIS.Ethics and dissemination:Ethical approval is not needed because this study will be based on data that already published. We will publish the findings of this study in a peer-reviewed journal and related conferences.PROSPERO registration number:CRD42020215546.

Matrine,oxymatrine, and compound Kushen injection from the roots of Sophora flavescens: an overview of their anticancer activities

In the present review, we updated current information on the chemistry, contents, and anticancer properties of matrine (MT), oxymatrine (OMT), and compound Kushen injection (CKI). The anticancer properties were focused on lung, breast, and liver cancer cells because they are most susceptible. Sources of information were from Google, Google Scholar, PubMed, PubMed Central, Science Direct, PubChem, J-Stage, Directory of Open Access Journals (DOAJ), and China National Knowledge Infrastructure (CNKI). Reference was also made on botanical websites, such as Flora of China and World Flora Online. MT and OMT are dominant quinolizidine alkaloids from the roots of Sophora flavescens (Kushen) of the family Fabaceae. Against lung, breast, and liver cancer cells, MT and OMT inhibit cell proliferation; induce cell cycle arrest, apoptosis, and autophagy; restrict angiogenesis; and inhibit cell metastasis, invasion, and migration. The processes involve various molecular targets and signaling pathways. CKI is a traditional Chinese medicine (TCM) composed of root extracts of S. flavescens and Smilax glabra (Baituling) of the family Smilacaceae. With MT and OMT as major components, CKI has been approved for the treatment of cancer in China more than 20 years ago. In recent years, systematic reviews and meta-analysis have been undertaken to evaluate the anticancer effects of CKI. When CKI is used alone and in combination with chemotherapy of western medicine, there is much to be learned concerning their interactions besides their individual and integrated efficacy. Some perspectives of MT, OMT, and CKI are discussed, and their suggestions for future research are provided.
