Objective To investigate the best dose of treating diabetic renal insufficiency (DRI) with Tangduqing granules. Methods To establish model rats of DRI by the method of 5/6 nephrectomy and abdominal cavity injection with streptozotocin. The successful model rats with DRI were divided into four groups randomly:model group, high dose group, medium dose group, low dose group. Ten age-matched healthy male SD rats were served as controls (administered with NS 2 mL/d). Ten weeks later, contents of the BUN, SCr and urine protein excretion in 24 hours were determined. And to detect the best dose of treating DRI with Tangduqing granules by evaluating the effect of Tangduqing. Results Tangduqing had the function of reducing contents of BUN, SCr and urine protein excretion in 24 hours of rats with renal insufficiency. Conclusions Tangduqing may effectively delay the development of renal failure. The therapeutic effects of medium dose group were the best.

Early intervention plays a very important role in social adaption and learning of the children who are at risk.It has been moved to a more empirical direction,that is to say,there has been a substantial movement toward developing and implementing evidence-based services in the early intervention field.We introduce 3 concrete evidence-based programs targeting children who are at risk.Moreover,we will consider two issues in early intervention.
