应用磁共振波谱研究针刺合谷穴前额叶神经递质Glu与GABA相关性＊

目的 探讨手针针刺健康受试者右侧合谷穴，前额叶Glu⁺、Glx⁺及GABA⁺浓度变化差异及相关性，从兴奋和抑制性神经递质关系方面初步探讨针刺效应的脑机制。方法 录入健康志愿者76名，随机接受手针及纤毛针两种刺激，并采集刺激前和刺激时BOLD功能磁共振脑成像（fMRI）及磁共振波谱（MRS）数据，分析手针和纤毛针组刺激前与刺激时Glu⁺、Glx⁺、GABA⁺浓度差异及相关性，以及Glu⁺、Glx⁺与GABA⁺浓度的相关性。结果 手针及纤毛针组间和组内各亚组（依据不同BOLD信号）针刺前与针刺时Glu⁺、Glx⁺、GABA⁺浓度差异无统计学意义（P均>0.05）。但手针组整组的Glu⁺、Glx⁺、GABA⁺，零、负激活亚组的Glu⁺、Glx⁺和零激活GABA⁺针刺前与针刺时浓度呈正相关（P均<0.05）。针刺前手针组整组、零、负激活亚组的Glu⁺、Glx⁺均与GABA⁺呈正相关q（P均<0.05）；纤毛针组整组、正、负激活亚组Glu⁺、Glx⁺均与GABA⁺及零激活Glu⁺与GABA⁺均呈正相关（P均<0.05）；针刺时手针组整组、负激活亚组Glu⁺与GABA⁺呈正相关，零激活亚组Glx⁺与GABA⁺呈正相关（P均<0.05）。结论 针刺前与针刺时Glu⁺、Glx⁺与GABA⁺多呈正相关，可作为针刺脑机制研究的神经递质观察指标。     

李东垣论治泄泻理论探讨

李东垣的升脾阳法对于泄泻的治疗具有重要价值。泄泻的基本病机是脾虚湿盛，脾虚为病机之核心，或兼肺虚，或兼湿盛，或兼寒积，脾虚则清阳不升，正所谓"清气在下，则生飧泄"。治疗以补脾健脾为本，根据不同的病机或补益脾肺，或燥湿健脾，或攻逐寒积，或健脾升阳。     

李应东教授从脾气虚论治高脂血症

李应东教授认为脾胃气虚,脾失健运导致膏脂生成及转运输布异常是高脂血症发病的关键,脾气虚形成的痰浊、血瘀作为病理产物和致病因子贯穿疾病始终,以脾气虚为本,痰浊、血瘀为标,治疗上以益气健脾,化痰祛瘀为主,方选四君子汤、二陈汤及桃红四物汤随症加减治疗。     

李兴勇教授治疗膝关节骨性关节炎经验小结

李兴勇教授认为,膝关节骨性关节炎(KOA)为本虚标实之证,以风、寒、湿、热瘀阻经络为标,以肝肾亏虚为本,宜以补肝益肾、活血化瘀、清热利湿等法分型论治,同时结合西医疗法,充分发挥中西医结合的优势,做到标本兼治。     

Biallelic mutations in DYNC2LI1 are a rare cause of Ellis‐van Creveld syndrome

Ellis‐van Creveld syndrome (EvC) is a chondral and ectodermal dysplasia caused by biallelic mutations in the EVC, EVC2 and WDR35 genes. A proportion of cases with clinical diagnosis of EvC, however, do not carry mutations in these genes. To identify the genetic cause of EvC in a cohort of mutation‐negative patients, exome sequencing was undertaken in a family with 3 affected members, and mutation scanning of a panel of clinically and functionally relevant genes was performed in 24 additional subjects with features fitting/overlapping EvC. Compound heterozygosity for the c.2T>C (p.Met1?) and c.662C>T (p.Thr221Ile) variants in DYNC2LI1, which encodes a component of the intraflagellar transport‐related dynein‐2 complex previously found mutated in other short‐rib thoracic dysplasias, was identified in the 3 affected members of the first family. Targeted resequencing detected compound heterozygosity for the same missense variant and a truncating change (p.Val141*) in 2 siblings with EvC from a second family, while a newborn with a more severe phenotype carried 2 DYNC2LI1 truncating variants. Our findings indicate that DYNC2LI1 mutations are associated with a wider clinical spectrum than previously appreciated, including EvC, with the severity of the phenotype likely depending on the extent of defective DYNC2LI1 function.     

Local cutaneous nerve terminal and mast cell responses to manual acupuncture in acupoint LI4 area of the rats

Previous studies have shown that the effects of manual acupuncture (MA) are contributed by collagen fibers and mast cells in local acupoints, at which acupuncture stimulation causes various afferent fiber groups to be excited. However what happens in local nerve fibers and mast cells after MA remains unclear. The aim of this study was to examine the response of cutaneous nerve fibers and mast cells to MA stimulation in acupoint Hegu (LI4). The contralateral LI4 of the same rat was used as a non-stimulated control. Immnohistochemistry analysis were carried out to observe the expression of histamine (HA), serotonin (5-HT) and nociceptive neuropeptides, calcitonin gene-related peptide (CGRP) and substance P (SP), in the LI4 area. Mast cells were labeled with anti-mast cell tryptase antibody and simultaneously with HA or 5-HT primary antibodies to observe their co-expression. Our results showed that SP and CGRP were expressed more highly on the cutaneous nerve fibers of LI4 after MA stimulation than that of the control. Mast cells aggregated in close proximity to the blood vessels in intra-epidermis and dermis and some of them with degranulation in the lower dermis and subcutaneous tissue of LI4. Both mast cells and their granules appeared with HA (+) and 5-HT (+) expression at stimulated L14 sites, while a few intact mast cells with a little expression of 5-HT and HA were distributed in areas of non-stimulated L14. The results indicated that local cutaneous nerve terminals and mast cells responded to MA with higher expression of SP and CGRP in nerve fibers, as well as with aggregation and degranulation of mast cells with HA and 5-HT granules at acupoint LI4. These neuroactive substances may convey signals to certain pathways that contribute to the effects of acupuncture.
