辛伐他汀治疗原发性高脂血症30例.8周末胆固醇(TC)下降35.3%,低密度脂蛋白胆固醇(LDL-C)下降46.6%.甘油王酯(TG)下降30.6%.与治疗前比较有显著差异(P<0.01),但高密度脂蛋白胆固醇(HDL-C)升高不明显(P>0.05)。降低TC、LDL—C方面优于非诺贝特组(P<0.01),降低TG两者无差异(P>0.05),而升高HDL—C方面差于非诺贝特组(P<0.05)。提示辛伐他汀可作为原发性高胆固醇血症的首选药物。 相似文献

目的:观察消瘀胶囊对预防家兔高脂血症形成的影响。方法:48只新西兰兔按血清胆固醇(TC)水平平均分成6组,即正常对照组,高脂模型组,消瘀胶囊小剂量组(25mg/kg),中剂量组(50mg/kg),大剂量组(100mg/kg),血脂康组(65mg/kg)。除正常对照组,余各组给予高脂饲料及相应药物,连续服用31天后,测定各组兔空腹血脂水平。结果:消瘀胶囊各组可使兔血清TC,低蛋度脂蛋白胆固醇(LDL-c)显著地低于高脂模型组(P<0.01);使血清甘油三酯(TG)下降13.2%-43.6%,尤其大剂量组明显(P<0.05);对高密度脂蛋白胆固醇(HDL-c)虽然没有升高作用,但可使TC/HDL-c比值明显下降(P<0.01)。结论:消瘀胶囊具有预防家兔高脂血症形成的应用。 相似文献

Objective To evaluate myocardial apoptosis with 99Tcm-C2A-GST myocardial imaging using the recombined C2A domain of Synaptotagmin Ⅰ by gene engineering. Methods ( 1 ) The C2A gene was inserted into the prokaryotic glutathione S-transferate (GST) fusion protein expression plasmid pGEX-6P-1. The recombinant plasmid was transformed into E. coli BL21. C2A-GST fusion protein was purified after BL21 was induced with isopropyl-β-D-1-thiogalactopyranoside (IPTG). (2)The activity of fusion protein was identified by cell binding test with fluorescein-5-isothiocyanate (FITC)-C2A-GST. (3) The C2A-GST fusion protein was labeled with 99Tcm using 2-iminothiophene hydrocoride method. Radiochemical purity was determined with thin layer chromatography. (4)99Tcm-C2A-GST (7.4 MBq) was injected to ischemia-reperfusion rat models through tail vein. The image was acquired with SPECT at 1 h after injection, and then hearts were removed, rinsed with saline and dyed with triphenyl tetrazolium coride (TTC). The ischemic myocardium was separated from the viable myocardium and was weighted. Its radioactivity was measured by gamma counting. The difference of uptake of radiotracer between ischemic myocardium and normal myocardium was compared using percentage activity of injected dose per gram of tissue ( % ID/g) with standard deviation. SPSS 12.0 and t-test were used for data analysis. Results ( 1 ) C2A-GST fusion protein wassuccessfully expressed and its relative molecular weight was 3.8 × 104. (2) FITC-C2A-GST binding to apoptotic cells could be observed by fluorescent microscopy. (3) The radiochemical purity of 99Tcm-C2A-GST was (98.90 ±0.43)%. (4)The imaging studies showed that there was focal uptake of radioactivity in the ischemic myocardium. In vitro uptake of 99Tcm-C2A-GST was (2.41 ±0.32) % ID/g by the ischemic myocardium, however 99Tcm-C2A-GST-N-hydroxysuccinimide (C2A-GST-NHS) was (0. 82 ± 0. 24) % ID/g. There was statistically significant difference between those two groups (t = 10. 6, P <0.01 ). Conclusion The C2A domain of Synaptotagmin Ⅰ expressed by gene engineering can be used as the tracer for noninvasive detection of ischemic myocardium in the ischemia-reperfusion rat model. 相似文献
