参麻益智胶囊治疗老年血管性痴呆的临床研究

为了观察参麻益智胶囊治疗老年血管性痴呆（VD）的临床疗效。将68例VD患者随机分为治疗组和对照组,治疗组用参麻益智胶囊,对照组用西药喜得镇,采用双盲双模拟法给药。结果参麻益智胶囊可以明显改善临床症状,提高智量表积分,改善患者记忆认知功能,恢复患者神经功能缺损,改善日常生活能力,血液流变学指标及脑部功能活动状态,其中在改善临床症状方面治疗组明显优于对照组（P＜0．05）,说明参麻益智胶囊治疗老年血管性痴呆疗效肯定,在观察中未发现有任何毒副作用。     

冬连胶囊对实验性糖尿病大鼠早期胰岛素抵抗的影响

Objective To investigate the effects of Donglian Capsule(the combination of Ophiopogonis Tuber Polysaccharide with Rhizoma Coptidis Alkaloids, OPRA for short, Component of Chinese medicine)on early insulin resistance in experimental diabetic rats. Methods The animal model of insulin resistance in 2 type diabetic was established by injecting low dose of STZ in 60 high fat-fed SD rats. After one week, the successful models were randomly divided into 4 groups: untreated, high and low OPRA-treated, mefformin-treated group, Meanwhile, a normal control group was designed. After four weeks, the differences of FBG, PG, INS and C-P were compared among the groups. Results The OPRA can significantly reduced the level of serum TC and FBG, increased the C-E ]Lightened the IRI(P<0.01). Conclusion The OPRA can reduce the level of serum TG and FBG, and decrease insulin resistance to protect the β-cell function.     

海冬花粉对下丘脑性肥胖大鼠的影响

目的 :探讨药食同源的中药制剂海冬花粉的减肥作用及机理。方法 :应用L 谷氨酸钠致下丘脑性肥胖的大鼠模型研究海冬花粉的药效及其机理。结果 :海冬花粉 (2.5 g·kg^-1)能降低肥胖动物的Lee′s指数 (身高体重指数 ) ,使脂肪细胞变小 ;对血清三碘甲腺原氨酸 (T³ )、甲状腺素 (⁴ )、胰岛素和醛固酮水平无明显影响 ;对摄入热量无影响 ;无腹泻现象。结论 :海冬花粉具减肥作用 ,其减肥不影响甲状腺功能和水盐代谢 ,不引起腹泻和不抑制食欲。其减肥机理与阻碍脂肪细胞的增大 ,减少脂肪蓄积有关。

舒血宁片治疗冠心病的临床研究

４６例冠心病患者随机按２：１比例分为治疗组和对照组，分别给予舒血宁Ⅱ号片与Ⅰ号片。结果表明舒血宁Ⅱ和Ⅰ号片均可改善冠心病心绞痛症状，总有效率分别为６０．００％和８３．８７％，两者无显著差异；但对中、重度患者Ⅱ号片的总有效率为８３．３３％，Ⅰ号片仅为３３．３３％，两才比较差异显著；它们对心电图也有一定的改善作用，总有效率分别为６０．００％和７４．１９％，两者无显著差异；对血脂ＴＣ和ＴＧ两药都有一定的     

糖尿病氧自由基与蛋白质糖基化反应的关系

近10多年来的研究证实,糖尿病时由于长期高血糖,糖基化反应(即Maillard反应)增强,体内许多重要蛋白质的性质发生了变化,这与糖尿病众多晚期并发症的发生有密切的关系^〔1〕。有些研究证实,蛋白质糖基化反应过程中氧自由基产生增加,反过来氧自由基反应增强也促进蛋白质的糖基化^〔2〕。支持这一观点的动物实验和体外实验较多,尚需要大量的临床病人的实验证实。为此,我们对老年性糖尿病人(NIDDM)体内包括氧自由基代谢和蛋白质糖基化的多项指标作了研究,以便证实氧自由基反应和糖基化反应相互促进的关系。     

冬连三七组分调控AGEs/p38MAPK改善糖尿病动脉粥样硬化兔血管内皮损伤的机理研究

目的:研究冬连三七组分(Composition of Ophiopogon polysaccharide,Notoginseng total saponins and Rhizoma Coptidis alkaloids,CONR)调控AGEs/p38MAPK信号转导通路,改善糖尿病动脉粥样硬化(diabetic atherosclerosis,DA)兔血管内皮损伤的机制。方法:雄性新西兰大白兔分为空白组、模型组、CONR高剂量组、CONR低剂量组、SB203580组、辛伐他汀组;静脉推注四氧嘧啶并且配合腹主动脉内膜球囊损伤术诱导DA模型。CONR高、低剂量组每日分别给予CONR 450 mg/kg、CONR 150 mg/kg灌胃10周;辛伐他汀组给予3 mg/kg辛代他汀灌胃10周;SB203580组给予p38MAPK抑制剂2 mg/kg腹腔注射,12 h重复给药10周;空白组每日给予生理盐水20 ml灌胃。结果:各实验组对AGEs高表达均有降低作用,与模型组比较差异具有统计学意义。各实验组对p-p38MAPK蛋白高表达均有抑制作用,与模型组比较,差异具有统计学差异(P0.01)。CONR高、辛伐他汀组对p-p38MAPK蛋白的抑制作用优于SB203580组(P0.01)。CONR低高剂量组、SB203580组及辛伐他汀组显著降低DA大兔ET水平,实验各组NO活性较模型组显著增强(P0.01)。冬连三七组分明显抑制了DA兔胸主动脉血管内皮细胞的损伤。结论:冬连三七组分可能通过干预AGEs/p38MAPK信号转导通路改善DA兔的血管内皮损伤。
