雷公藤多苷对类风湿关节炎大鼠Ras/Raf1原癌基因表达的影响

目的：探究雷公藤多苷对类风湿关节炎大鼠关节血清及组织Ras/Raf1表达的影响。方法：将60只SD大鼠随机分为对照组、模型组和干预组,每组20只。模型组与干预组建立大鼠风湿关节炎模型,干预组用雷公藤多苷干预,对照组和模型组给予等量生理盐水。以足趾肿胀度为模型标准和疗效判定指标,实验终点通过酶联免疫吸附试验法（ELISA）检测大鼠血清Ras、Raf1以及炎症介质肿瘤坏死因子-α（TNF-α）、白细胞介素-6（IL-6）水平,实验终点通过Western Blotting检测大鼠滑膜组织Ras和Raf1蛋白表达量并对大鼠踝关节进行HE染色分析。结果：ELISA结果表明,与对照组比较,模型组血清Ras、Raf1、TNF-α、IL-6显著升高（均P<0.01）,与模型组比较,干预组血清Ras、Raf1、TNF-α、IL-6显著降低（均P<0.01）;Western Blotting结果表明：与对照组大鼠比较,模型组大鼠滑膜组织Ras、Raf1显著升高（均P<0.01）,与模型组比较,干预组大鼠滑膜组织Ras、Raf1显著降低（均P<0.05）。HE染色表明：与对照组比较,模型组病理总评分升高（P<0.01）,与模型组比较,干预组病理总评分下降（P<0.05）。结论：雷公藤多苷可抑制大鼠血清炎症介质释放并降低外周血和关节组织中Ras、Raf1蛋白的表达,起到骨保护作用。     

Effects of triptolide on hippocampal microglial cells and astrocytes in the APP/PS1 double transgenic mouse model of Alzheimer’s disease

The principal pathology of Alzheimer's disease includes neuronal extracellular deposition of amyloid-beta peptides and formation of senile pl aques,which in turn induce neuroinflammation in the brain.Triptolide,a natural extract from the vine-like herb Tripterygium wilfordii Hook F,has potent anti-inflammatory and immunosuppressive efficacy.Therefore,we determined if triptolide can inhibit activation and proliferation of microglial cells and astrocytes in the APP/PS1 double transgenic mouse model of Alzheimer's disease.We used 1 or 5 μg/kg/d triptolide to treat APP/PS1 double transgenic mice(aged 4–4.5 months) for 45 days.Unbiased stereology analysis found that triptolide dose-dependently reduced the total number of microglial cells,and transformed microglial cells into the resting state.Further,triptolide(5 μg/kg/d) also reduced the total number of hippocampal astrocytes.Our in vivo test results indicate that triptolide suppresses activation and proliferation of microglial cells and astrocytes in the hippocampus of APP/PS1 double transgenic mice with Alzheimer's disease.     

雷公藤醇提物对骨髓细胞增殖和凋亡的影响

目的:观察雷公藤醇提物对大鼠骨髓细胞增殖、周期和凋亡的影响。方法:体外培养大鼠股骨骨髓细胞,经不同浓度的雷公藤醇提物作用后,采用MTT比色法检测对骨髓细胞增殖的影响;采用流式细胞仪PI单标法检测对骨髓细胞周期的影响;采用流式细胞仪Annexin V-FITC/PI双标法检测对骨髓细胞凋亡的影响。结果:雷公藤醇提物可明显抑制正常骨髓细胞增殖,并且此抑制作用呈明显的时间和剂量依赖性。细胞周期进程的结果显示,与正常对照组相比,雷公藤组G0/G1期细胞比例显著增多,S期和G2/M期细胞比例显著减少,细胞增殖指数显著降低,早期凋亡率显著升高。结论:雷公藤醇提物可明显抑制骨髓细胞增殖,使骨髓细胞阻滞于G0/G1期,并能诱导细胞凋亡。     

黄葵胶囊联合雷公藤多苷片治疗Ⅳ期糖尿病肾病的疗效观察

目的:观察黄葵胶囊联合雷公藤多苷片治疗糖尿病肾病的疗效。方法:将135例糖尿病肾病Ⅳ期患者分为对照组、黄葵胶囊组和联合用药组,三组患者均给予糖尿病基础治疗。对照组:使用血管紧张素Ⅱ受体拮抗剂(ARB)控制血压及降蛋白尿治疗。黄葵胶囊组:对照组基础上加用黄葵胶囊5粒,每日3次口服。联合用药组:对照组基础上加用黄葵胶囊5粒,每日3次口服;雷公藤多苷片1 mg/(kg.d),分3次口服。观察治疗前和治疗2、4、8、12周后24 h尿蛋白定量、血白蛋白、肾功能、肝功能、血脂、血常规等变化。结果:三组治疗前24 h尿蛋白定量无统计学差异(P>0.05),治疗4周后黄葵胶囊组和联合用药组尿蛋白均较治疗前降低,联合用药组差异有统计学意义(P<0.01);治疗8周后黄葵胶囊组和联合用药组尿蛋白均较治疗前显著降低(P<0.01),且联合用药组较对照组降低更显著(P<0.01)。治疗12周后黄葵胶囊组和联合用药组尿蛋白较治疗前进一步降低,且与对照组相比均有统计学差异(P<0.05和P<0.01)。其余指标变化无统计学意义(P>0.05)。结论:黄葵胶囊、雷公藤多苷片治疗Ⅳ期糖尿病肾病均能降低尿蛋白,从而延缓肾功能进展,但联合治疗组不仅起效快,而且效果更明显。

Abstract： Objective To observed the efficacy of tripterygium wilfordii polyglycoside and captopril in the treatment of children with Henoch-Schonlein purpura nephritis kidney disease model. Methods One hundred and one children diagnosed with kidney-type purpura nephritis from May 1996 to June 2009 in our hospital, were respectively, randomly divided into treatment group (58 cases,oral tripterygium wilfordii polyglycoside and captopril) and the control group (43 patients, single-dose oral prednisone), observation of therapeutic effects of drugs in the two groups of children with edema, hypertension, hematuria, proteinuria efficacy, using SPSS10.0 software for statistical analysis. Results Fifty-one patients were cured (88%), effective in 7 patients (12%) in the treatment group, the control group cured 26 cases (61%), effective in 17 cases (39%), there was significant difference between the two groups (P<0.01). Pairs of edema, hematuria, hypertension were significantly different between the two groups(P<0.05 or P<0.01), and the efficacy of proteinuria was also significantly different (P<0.01). Conclusions Tripterygium wilfordii polyglycoside and captopril treatment of children with Henoch-Schonlein purpura nephritis kidney disease model is superior to single-dose prednisone, it is worth clinical application.
