脊髓小脑共济失调2型家系ATXN2基因中间重复病例表型与分子遗传学特征

目的探讨脊髓小脑共济失调2型(SCA2)致病基因ATXN2异常等位基因中间重复个体的表型和分子遗传学特点。方法针对2005—2018年中日友好医院神经科运动障碍与神经遗传病研究中心收集的1383个常染色体显性遗传共济失调家系的先证者和部分家系成员,采用荧光标记毛细管电泳片段分析方法进行动态突变检测,对携带ATXN2基因中间重复的个体进行临床表型和遗传特征分析。结果共检出163个家系(包含先证者和家系成员共203人)携带异常扩展的ATXN2基因CAG重复序列,其中93个家系中有107例的异常扩展等位基因重复次数在29~34次之间。在其中的20个亲子对中,父系遗传16个,异常等位基因的代间扩展增加0~28次,母系遗传4个,异常等位基因的代间扩展增加0~4次。结论对于临床拟诊SCA2家系患者,需对其亲代或成年子代个体进行ATXN2基因检测,以免漏诊。动态突变基因检测有助于识别中间重复的个体,对明确家系致病基因和遗传咨询至关重要。     

Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The anti liver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its "pharmacodynamic group". By searching the research on the anti hepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an anti hepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an anti hepatoma role. Network pharmacological analysis showed that the core targets of the "pharmacodynamic group" for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and "pharmacodynamic group", it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and "pharmacodynamic group" in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and "pharmacodynamic group".     

Diagnosis of intrahepatic cholangiocarcinoma by Raman spectroscopy provides high efficiency: A protocol for systematic review and meta-analysis

Background:We aim to evaluate the efficiency of Raman spectroscopy (RS) in diagnosing suspected patients with intrahepatic cholangiocarcinoma (ICC), manifested by diagnostic sensitivity, specificity, and accuracy.Methods:We will research widely the articles concerning the use of RS in ICC through authenticated database including PubMed/Medline, EMBASE, Web of Science, Ovid, Web of Knowledge, Cochrane Library, and CNKI between January 2012 and November 2020, retrieving at least 1500 spectra with strict criteria. This study will be carried out in accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We are going to summarize the test performance using random effects models.Results:Based on the pooled sensitivity, specificity, and diagnostic accuracy, we intend to provide the relative diagnostic efficiency in ICC through RS.Conclusion:Through this systematic review and meta-analysis, we intend to provide the pooled sensitivity, specificity and diagnostic accuracy of RS in the diagnosis of suspected ICC. Other parameters like positive likelihood ratios (LR), negative LR, diagnostic odds ratio (DOR), and area under curve (AUC) of the summary receiver operating characteristics (SROC) curve will also be calculated and related figures will be drawn to help illustrate the efficacy of RS in the diagnosis of ICC.     

中医药治疗动脉粥样硬化临床研究进展

中医药防治动脉粥样硬化的研究具有良好的实践基础和应用前景,治疗方法可归于四类,即活血化瘀、化痰调脂、痰瘀同治、扶正祛邪,研究者辨证施治,多在临床上取得了满意的疗效。目前研究仍存在一些亟待解决的问题:首先,中医药防治动脉粥样硬化临床研究重复性差,缺乏大样本、多中心、高质量的临床研究及系统深入的实验研究;其次,对专家经验方及中药复方研究不够深入,临床药效物质基础不明确,缺乏对其作用机制的深入挖掘;再次,目前的研究不够系统和全面,主要集中在对动脉粥样硬化的形成和发展过程的研究,对斑块易损性研究相对较少。针对上述问题,今后应加强中医药治疗动脉粥样硬化的基础及临床研究,为治疗提供更加明确的理论依据和临床证据;同时,建立具有中医特色的研究模式,以中医宏观辨证理论为指导,利用现代医学技术,参考现代中药药理实验结果选药组方,扩大辨证选药思路,加强对中药方剂配伍规律的研究,以及对其有效成分的分离提取、鉴定和作用机制研究,并将传统组方理论与针对发病机制的对病治疗相结合,多角度、多层次探索中医药的作用机理。此外,应不断深入探索动脉粥样硬化的发病机制,并结合细胞工程、分子生物学及基因科学,积极研究中医药的药效学基础和机制。     

胃癌微创外科临床研究进展及展望（2000-2020）

目前临床研究已证实腹腔镜胃癌根治术治疗早期胃癌的安全性、可行性和有效性。基于此，第4版日本《胃癌治疗指南》推荐腹腔镜手术治疗临床Ⅰ期远端胃癌。然而，腹腔镜胃癌手术治疗进展期胃癌的有效性和安全性仍存争议。中国腹腔镜胃肠外科研究组（CLASS研究组）发起的CLASS-01研究顺利完成，提供了全球首个局部进展期胃癌腹腔镜手术安全性和疗效的前瞻性多中心证据。胃癌外科的主流方向在从“大切口和扩大化手术切除”逐渐向“微创、精准化手术”转变，以使手术安全性和病人术后生活质量最优化。     

基于LC-MS的甘草炮制雷公藤降低肝毒性的代谢组学研究

目的 观察甘草炮制雷公藤Tripterygium wilfordii后对小鼠血清中代谢产物的影响，初步探讨其降低肝毒性的可能代谢通路。方法 将C57BL/6小鼠随机分为对照（Con）组、雷公藤（Raw）组、甘草炮制雷公藤（Pro）组，观察小鼠肝组织病理变化，检测小鼠肝功能生化指标、炎症因子水平；利用液质联用（LC-MS）技术结合代谢组学方法，对各组间的代谢差异进行表征。结果 与Raw组相比，Pro组小鼠肝组织损伤显著改善，肝功能生化指标、炎症因子水平显著降低，表明甘草炮制雷公藤后可以降低小鼠肝毒性；共筛选出脂肪酸、磷脂酸、甘油酯、磷脂酰胆碱、胆酸等12个潜在生物标志物，主要涉及脂肪酸生物合成、甘油磷脂代谢、花生四烯酸代谢等9个代谢通路。结论 甘草炮制雷公藤可有效降低小鼠的肝毒性，其机制可能与调节脂肪酸代谢等通路相关，为其临床合理应用提供参考依据。     

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。
