《儒门事亲》四穴考辨

《儒门事亲》文中有四穴,即水分、？谷、廉泉、中注。其中水分穴的定位是错误的,应当予以改正,而张从正治疗水湿疾病建议采用直接灸水分穴,并提出此类疾病此穴禁针。三阳络的别名有“？谷”和“骨空”,可治疗循经所过的疾病。《儒门事亲》中的廉泉穴,即是经外奇穴金津玉液,并提出火针此穴治疗火热舌肿为禁忌。虽然“中注”不能明确所指何穴,有“合谷”“阳溪”“大都”等穴的可能性,但是可以从中得到启示：运用某些四肢末端的腧穴（如张从正所说的“中注”和后溪）治疗风淫末疾。     

龟地散对骨质疏松大鼠骨代谢的影响

目的 本实验对龟地散在去卵巢大鼠所致骨质疏松大鼠骨代谢方面的影响进行了探讨。结果 实验显示，龟地散能明显降低骨质疏松大鼠尿羟脯氨酸和尿钙含量（P＜0．01，P＜0．05），并可明显增加血清碱性磷酸酶含量（P＜0．01）和骨钙素水平（P＜0．05）。结果还显示，龟地散对血清钙水平有显升高作用（P＜0．05），但对血清磷水平的影响却不明显。结论 提示龟地散能明显改善去势大鼠所致骨质疏松。     

基于知识图谱构建和定性访谈法探析张忠德教授辨治间质性肺病临床特征与方药规律＊

目的 构建个性化知识图谱技术和定性访谈法结合，进一步挖掘张忠德教授辨治间质性肺疾病临证特征与用药规律。方法 采用回顾性分析，系统收集张忠德教授广东省中医院门诊2010年8月至2020年8月治疗间质性肺疾病病历，按照诊断标准、纳入标准、排除标准，严格筛选后，通过广东省中医院大数据挖掘团队中医药大数据智能处理与知识服务系统进行数据挖掘分析，并通过多元化视觉定性访谈法，将定量与定性分析有效结合。结果 共筛选出347首方，共141味药物，常用药物频次 ≥ 84次的药物有10味，其中党参、麦芽、黄芪、紫菀、白术等为核心用药，通过症状与药物推理知识地图显示，党参、炒麦芽、黄芪、大枣、太子参、山萸肉、巴戟天等为主要治疗用药；临证遣方用药知识关联分析，得知咳嗽、耳鸣、心悸、水肿、头痛、胸闷、恶寒等为多见，针对咳嗽，首选紫苏子、橘红、桂枝等温肺降气通阳之品等；频繁聚集显示，常用药对炒麦芽-炒白术、黄芪-党参、黄精-菟丝子、前胡-紫菀、炙枇杷叶-浙贝母等；聚类分析结果得到4组关系密切的聚类新药物组合；以脾为中轴，肺肾共扶为主的“平调五脏论”，分期阶梯辨治间质性肺疾病。结论 张忠德教授认为间质性肺疾病，虚实夹杂为多见，应从肺、脾、肾着手，采用平调五脏论分期阶梯辨治，用药配伍精简，以和为贵，以平为期。     

DREADD: A Chemogenetic GPCR Signaling Platform

Recently, we created a family of engineered G protein-coupled receptors (GPCRs) called DREADD (designer receptors exclusively activated by designer drugs) which can precisely control three major GPCR signaling pathways (Gq, Gi, and Gs). DREADD technology has been successfully applied in a variety of in vivo studies to control GPCR signaling, and here we describe recent advances of DREADD technology and discuss its potential application in drug discovery, gene therapy, and tissue engineering.     

《辅行诀》抄本寻踪

《辅行诀五脏用药法要》原藏敦煌藏经洞,1908年为法国伯希和盗掠,守洞道士王圆篆在为伯希和装箱时暗藏之,1918年售予河北省威县张僵南,僵南传其嫡孙大昌,毁于1966年“文革”初,“文革”期间张大昌将抄写本寄赠中国中医研究院,中国中医研究院加以整理,于1975年打印35本内部交流（简称“中研本”）,继而王雪苔先生两次亲访张大昌,收集到两个抄本,经整理收录于1988年江西科学技术出版社《敦煌古医籍考释》（简称“考释本”）;二十世纪九十年代中国中医研究院中国医史文献研究所派王淑民先生陶广正先生再访张大昌,收集到3个抄本,经整理收录于1998年江苏古籍出版社的《敦煌医药文献辑校》（简称“辑校本”）。今仍有大昌弟子抄本传世。     

《伤寒杂病论》中附子的功用及减毒方法探析

目的：探讨《伤寒杂病论》中附子的功用及减毒方法。方法：依据历代医家论述张仲景《伤寒杂病论》中附子回阳救逆、补火助阳、散寒止痛等功效的应用及常用药对的配伍机理,并结合现代研究成果对附子的减毒方法进行理论探讨。结果：减毒方法归结为炮制、煎煮、剂量、服法。结论：仲景在附子的应用上除注意炮制外,常遵循逐量而加、因人而异的用药原则,常依据患者年龄、体质、病程、病势给予适当剂量,且中病即止。

Evaluation of endocrine disrupting activity of plasticizers in polyvinyl chloride tubes by estrogen receptor alpha binding assay

Polyvinyl chloride (PVC) tubing is an indispensable medical material for extracorporeal circulation therapy. However, di(2-ethylhexyl)phthalate (DEHP), a suspected endocrine disruptor, can be eluted from PVC, suggesting that an alternative material that does not contain DEHP is needed for clinical applications. First, we evaluated the endocrine disrupting risks of the plasticizers contained in PVC tubes by investigating their binding affinities for the human estrogen receptor alpha (ERα). Our results revealed that, while DEHP has some binding affinity for ERα, neither epoxidized soybean oil nor tris(2-ethylhexyl)trimellitate (an alternative to DEHP) has any affinity for ERα. Second, we evaluated the endocrine disrupting risks of a tube made of newly developed plasticizer-free (PF) materials. We confirmed the presence of DEHP and detected several unidentified substances in plasma stored within the PVC tube. This plasma's competitive binding affinity for ERα was significantly higher than that of control plasma (P < 0.01). In contrast, the profile of plasma stored in the PF tube was similar to that of the control, both in terms of high-performance liquid chromatography chromatograms and competitive binding capacity for ERα, suggesting that the PF tube is biocompatible and is useful for reducing the elution of substances capable of binding to ERα.
