AIM: To investigate the influence of Astragalus Injection on morphology,cell cycle and oxidative stress of rat's glomerular mesangial cells(GMC) cultured with advanced glycation end products(AGEs). METHODS: GMC were incubated in culture medium containing AGEs in the presence of Astragalus Injection and aminoguanidin for 48 h.At the same time,the normal and control groups were established.Then the cultured GMC was stained by mixed fluorescence liquid and observed under fluorescence microscope.Cell cycle of GMC was analyzed using flowcytometry.The activity of SOD、MDA and GSH-PX in GMC supernatant were measured by test kit.The level of ROS was detected by flowcytometry. RESULTS: Morphology analysis showed that the morphology and structure of normal GMC were normal.The structure of most cells in AGEs was unclear,cell counts increased markedly and they grew intensively.Cell cycle analysis showed that cell percentage of S phase increased and G_0/G_1 reduced.The level of ROS,MDA remarkably increased,and SOD,GSHPX activity reduced.Whereas Astragalus Injection was added,cell morphology tended to be basically normal and cell counts decreased,the percentage of S phase also decreased.The level of ROS,MDA and the SOD,GSH-PX activity restored in comparison with the control groups. CONCLUSION: Astragalus Injection can prevent GMC from lesion caused by AGEs.Astragalus Injection may protect GMC from retarding the progression of diabetic nepropathy by partially inhibiting the occurrence of oxidative stress.

Objective To determine clinical characteristics and the effects of drug-eluting stents on the occurrence of major adverse cardiac events during percuteneous coronary artery interventional(PCI)and long- term outcomes in patients with chronic renal insufficiency(CRI).Methods Nine hundreds and seventy three patients with angiographically-documented coronary artery disease(lumen inner diameter narrowing＞50%), included 516 patients complicated with experienced renal impairment(CRI group)and 457 with normal renal function(control group).Baseline clinical data and coronary angiographic features were recorded.Results Comparing with control group,patients in CRI group were older with higher incidence of hypertension or diabetes and simultaneously complicated by reduced left ventricular ejection fraction,and more complex coronary lesions(type C).During follow-up(mean 17 months),the mortality was significantly higher in CRI than in control group(6.2% vs 3.3%,P＜0.05),but the former with CRI was significantly lower by using drug-eluting stents in comparing with bare-metal stents(4.1% vs 8.5%,P＜0.05).Conclusion Patients with CRI often complicated with severe coronary artery disease,the mortality after PCI would be significantly reduced by using drug-eluting stents.
