基于复杂网络的真武汤治疗糖尿病肾病的靶点作用研究

目的:从复杂系统角度对真武汤治疗糖尿病肾病的作用机制进行研究。方法:以"茯苓"、"白术"、"芍药"、"附子"、"生姜"为关键词检索中国中药化学成分数据库、Drugbank数据库和《中华人民共和国药典》(2010版)获取中药、成分、靶点信息,并建立数据集,以Cytoscape软件为载体,构建中药-成分-靶点之间的复杂网络模型,并推测出药物组方与作用靶点之间的关系。结果:中药-成分-靶点网络是一个多途径、多环节的小世界网络,部分节点度相对较低,且各药物的重复靶点较少,表明该网络具有无标度属性;聚类结果表明,各味中药中至少含有一种有效成分与靶点存在作用关系。结论:真武汤在糖尿病肾病的治疗中存在能够作用于相关靶点的有效成分。     

胸腺修饰诱导同种异体静脉移植的免疫耐受研究

Objective To investigate the possibility of inducing immune tolerance to vein trans-plantation in rats by intrathymic injection of allogene. Methods MHC antigen extracted from splenic cells of donor Wistar rats was intrathymically injected to recipients SD rats, and donor Wistar femur vein was transplanted after 2 weeks. Forty-eight SD rats were randomly divided into 4 groups: group A ( femur vein autograft) ,group B ( femur vein allograft) ,group C ( femur vein allograft with use of immunosuppressant), group D (intrathymus injection). Imaging, histology and immunological assays of these groups were carried out 2 weeks after the transplantation. Results Histologic parameters that were tested were better in group D than those in group B. The concentration of serum IFN-γ in group B was significantly higher than that in groups A, C and D [ ( 86. 707±10.928 ) ng/L vs (29.328±4. 170), (69.076±8.059) and (63.355± 4.895) ng/L respectively, P < 0.05 ]. The concentration of serum IL-4 in group B was obviously lower than in groups C and D [ (23.656±3.369) ng/L vs (29.425±4.174) and ( 31.000±4.659) ng/L re-spectively,P < 0.05 ]. Conclusion Intrathymus injection of allogenic antigen might induce specific im-mune tolerance to femur vein transplantation in rats.

纳络酮对全脑缺血大鼠的神经保护作用研究

全脑缺血后如何保护脑功能、减轻缺血/再灌注损伤是目前研究热点,但有效的神经保护剂并不多,仅tempol、MK-801等在实验中证明有效。纳络酮,作为传统意义的阿片受体拮抗剂,在许多实验和临床研究中亦被证明有神经保护作用,但仍存在较多争议。最近研究揭示纳络酮具有抑制钙超载的作用,本文通过研究其对钙结合蛋白表达的影响来探讨纳络酮的神经保护作用。1材料与方法实验选用健康SD大鼠29只,雌雄不拘,体重185.5～294.0g,建立窒息 艾司洛尔的大鼠心肺骤停模型[1],实验参数设计和记录均参照实验研究的Utstein模型。实验动物随机分为4组:假手术组…
