基于藏象理论探讨儿童发声性抽动从肺论治“金鸣五应”中医机理

抽动障碍为儿科较常见神经精神系统疾病,其中以发声性抽动临床治疗更具有挑战性。在中医理论中“金者肺,肺主声”,肺为娇脏,以华盖居高位,与外气相通,具有主气司呼吸、朝百脉主治节及主行水的生理功能,而小儿“肺常不足”,发声性抽动病位主要在肺系咽喉。从藏象理论肺之功能出发,发声性抽动的病因病机主要表现为金鸣五应,即外邪侵袭,金叩则鸣;肺为贮痰之器,金实则鸣;宣降失职,气机逆乱,冲逆则鸣;肺气不足,助血行无力,金虚则鸣;行水无权,气门失润,金鸣不破。从肺论治发声性抽动,旨在强调肺脏在发声中的重要作用,建立以肺为主,兼顾五脏的发声性抽动辨治体系,指导临床辨证论治。     

从TLR信号通路与伏毒致病论治系统性红斑狼疮

系统性红斑狼疮（SLE）是典型的自身免疫性疾病。大量研究表明TLR信号通路参与SLE的发生发展,而抑制TLR信号通路的活化可延缓SLE进程。TLRs基因的变异及其信号通路的异常活化介导SLE发生过程与伏毒致病过程有许多相似之处,其介导的炎症状态、复发过程也与中医之内生伏毒郁而化热、伏毒复萌类同。故文章从TLR信号通路与SLE的关系、SLE病因病机与伏毒相关性、中医药干预TLR信号通路延缓SLE进展机制等方面对SLE的病因病机及防治进行探讨。     

转化生长因子β2在小鼠心脏近端流出道隔心肌化过程中的作用

目的利用Cx43基因剔除（KO）小鼠模型,观察TGFβ2在心脏流出道隔的表达,探讨Cx43基因剔除小鼠心脏流出道隔心肌化异常与TGFβ2的关系;采用胚心脏体外培养技术,研究外源性TGFβ2是否促进流出道隔心肌化过程.方法选用胚E12.5～E15.5 d的Cx43基因剔除纯合型（Cx43-/-）、杂合型（Cx43＋/-）及野生型（Cx43＋/＋）C57/BL6小鼠作为研究对象,采用PCR方法鉴定基因型,免疫组织化学法测定TGFβ2;选用野生型E12.5进行胚心脏体外培养至E15.5,同时加用TGβ2不同剂量干预处理,免疫组织化学法测定肌节肌动蛋白α-SCA的表达.结果 Cx43 KO小鼠胚期心脏近端流出道隔心肌细胞明显减少,尤其以E13.5和E14.5的Cx43-/-小鼠为著.与Cx43＋/＋小鼠对照,Cx43-/-小鼠心脏近端流出道隔TGFβ2的表达明显降低,以E14.5较为显著;E14.5的Cx43＋/-小鼠表达也有降低.然而TGFβ2不同剂量干预组均没有见到明显的促进离体心脏心肌化的作用.结论 Cx43 KO小鼠心脏近端流出道隔存在明显的心肌化延迟.TGFβ2表达减少可能参与了Cx43-/-小鼠心肌化异常的发病机制.体外应用TGFβ2可能难以模拟在体的时空表达模式,或者心肌化的进行需要精确的TGFβ2的剂量和严格的培养条件.     

大鼠肌卫星细胞成肌分化的体外实验研究

目的探讨肌卫星细胞体外分化和烟碱型乙酰胆碱受体表达。方法采用胰蛋白酶消化SD乳鼠的骨骼肌卫星细胞,差速贴壁法纯化,进行体外培养,观察卫星细胞的分化过程,利用免疫组织化学方法进行鉴定。用银环蛇毒素鉴定细胞表面的烟碱型乙酰胆碱受体,并用乙酰胆碱刺激细胞观察其收缩功能。结果体外培养的肌卫星细胞分化为成肌细胞,融合成肌管。α-sarcomeric actin.skeletal myosin 和 desmin t抗体鉴定为阳性。ACh可刺激卫星细胞形成的肌管收缩。卫星细胞无明显的N—ACh受体表达;而卫星细胞形成的肌管经分化培养后N—ACh受体呈局部块状聚集。结论肌卫星细胞分化后形成的肌管具有收缩功能,并且在分化过程中逐渐合成烟碱型乙酰胆硅罟仕

Systematic Evaluation(Meta-analysis)of the Efficacy and Safety of Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)in the Treatment of Suppurutive Tonsillitis in Children

To systematically evaluate the efficacy and safety of Pudilan Xiaoyan Oral in Liquid(蒲地蓝消炎口服液)in the treatment of suppurative tonsillitis in children.In WanFang,CNKI,VIP,CBM,PubMed,Embase and Corchrane and other databases,relevant literatures about Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)in the treatment of pediatric suppurative tonsillitis were searched.The retrieval time was from the establishment of the database to April 2019.Relevant randomized controlled trials were extracted.The control group was treated with conventional antibiotics,and the observation group was treated with Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)based on the control group.After they were summarized and analyzed,Cochrane Handbook 5.1 evaluation standard and RevMan 5.3 software were used to determine the quality of literature.A total of 172 literatures were retrieved and 23 randomized controlled trials were included.A total of 1188 children were in the experimental group while 1175 children were in the control group,involving 2363 children with suppurative tonsillitis.Meta-analysis showed that the total effective rate of Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment was better than that of routine treatment(RR=0.88,95%CI(0.86,0.91),P<0.00001);Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment in children was better than that of routine treatment alone in term of temperature recovery,sore throat time,the reduction of tonsil purulent secretion.There were few reports of adverse reactions and no serious adverse reactions.To sum up,Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment can significantly improve the efficacy of children with suppurative tonsillitis,but due to the low quality of the included literature,it should be used cautiously.It is suggested that clinical randomized controlled trials should be designed with large sample size,multi-centers and conforming to international standards to improve the quality of evidence.
