当归芍药散防治老年期痴呆的物质基础与作用机理研究VI——当归芍药散精简方含药脑脊液对PC12细胞的保护作用

目的通过观察当归芍药散精简方(FBD)含药脑脊液对不同因素所致的PC12细胞损伤模型的保护作用,来探讨当归芍药散精简方(FBD)防治痴呆的作用机理.方法以MTT法观察FBD含药脑脊液对谷氨酸、过氧化氢、连二亚硫酸钠和氯化钾造成的PC12细胞损伤模型中细胞存活率的影响.结果连续多次给药(1.62g生药·kg-1)后0.5h～2.5h的FBD含药脑脊液对过氧化氢损伤的PC12细胞均有明显保护作用(P＜0.05～0.01),其中以1.5h的FBD含药脑脊液保护作用最明显;该时间点FBD含药脑脊液对谷氨酸、连二亚硫酸钠和氯化钾造成的PC12细胞损伤模型亦有显著保护作用,且随脑脊液添加量增加保护率捉高.结论FBD含药脑脊液对PC12细胞损伤有显著保护作用,其机制与抑制细胞内钙超载、对抗自由基的氧化损伤和谷氨酸的兴奋性毒性等有关.     

三保心对大鼠心肌缺血-再灌注损伤保护作用及其对体内外血栓形成影响的实验研究

目的：探讨三保心中药复方(三保心)对大鼠心肌缺血-再灌注损伤的保护作用及对体外血栓形成的影响。方法：结扎大鼠左冠状动脉前降支40min后再灌注180min。观察三保心对心肌缺血再灌注损伤大鼠超氧化物歧化酶(SOD)活性、丙二醛(MDA)含量和一氧化氮(NO)含量的影响。采用chandler法造成体外血栓和电刺激颈总动脉形成体内血栓，观察三保心对体内外血栓形成的影响。结果：三保心可显著提高心肌缺血-再灌注损伤大鼠血清中SOD活性，降低MDA含量，同时明显升高NO含量。三保心高剂量组明显延长大鼠体内血栓形成时间。各剂量组均能显著抑制大鼠体外血栓的形成。结论：三保心对缺血再灌注心肌损伤有一定的保护作用，其作用机制可能与扩张血管、提高氧自由基清除酶活性、抑制脂质过氧化反应有关。且具有抑制体内外血栓形成的作用。     

Placebo controlled evaluation of Xilei San,a herbal preparation in patients with intractable ulcerative proctitis

Background and Aim: Topical mesalamine or corticosteroid has shown efficacy in patients with ulcerative proctitis, but patients often become refractory to these interventions. Xilei San is a herbal preparation with evidence of anti‐inflammatory effects. We evaluated the efficacy of topical Xilei San in ulcerative proctitis patients. Methods: In a double blind setting, 30 patients with intractable ulcerative proctitis despite ≥ 4 weeks of topical mesalamine or corticosteroid were randomly assigned to True (n = 15) and placebo (n = 15). Patients in True received suppository Xilei San (0.1 g/dose per day of Xilei San), the other 15 received placebo suppository. The initial efficacy was evaluated on day 14. Primary endpoint of the trial was avoiding relapse during 180 days, relapse meant recurrence of active disease. Riley's index was applied for endoscopic and histological evaluations, while patients' quality of life was evaluated by an inflammatory bowel disease questionnaire. Results: On day 14, the number of patients who achieved remission, clinical activity index ≤ 4 in True was significantly higher versus placebo (P < 0.04). Likewise, at day 180, an 81.8% of patients in True were without relapse versus 16.7% in placebo (P < 0.001). Further, significant endoscopic (P < 0.01), histological (P < 0.02) and inflammatory bowel disease questionnaire (P < 0.04) improvements were observed in True, but not in placebo. Conclusions: This is the first controlled investigation showing significant clinical and endoscopic efficacy for Xilei San in patients with intractable ulcerative proctitis. Topical Xilei San was well tolerated, and was without safety concerns.
