RESUMO
Based on a description of the positioning and characteristics of the hospital and its development roadblocks and mission,the authors studied practical experiences in building a research hospital.The hospital has achieved a leap-forward development thanks to its pursuit of quality as lifeline,innovative research and translation,enhancement of its role in rescue medicine innovation,and leveraging branding effect of rescue medicine.
RESUMO
AIM: To investigate the effect of losartan on the mRNA expression of type 2 angiotensin II receptor and cytokines in diabetic rat kidney.METHODS: SD rats were randomly divided by following groups: control rats(group C),diabetic rats(group D) and diabetic rats treated with losartan (30(mg?kg~(-1)?d~(-1)),by gavage,group DT).At the end of 8-weeks study,mRNA expressions of the type 2 angiotensin II receptor(AT_2),transforming growth factor-?_1(TGF-?_1),platelet-derived growth factor-B(PDGF-B),tumor necrosis factor-?(TNF-?) and collagen Ⅳ in rats renal cortex were measured by RT-PCR,respectively.In addition,angiotensin Ⅱ level in renal cortex was determined by the radioimmunoassay.RESULTS: In group D,urine protein excretion(P
