The genome of infectious hepatitis B virus is a partially double stranded circular DNA, and that of replicative HBV is a covalently closed circular supercoiled DNA. The patients with chronic HBV infection manifest from non-active virus carrier state to severe active hepatitis, and 15%~25% of which will evolve decompensate cirrhosis and hepatocellular carcinoma.

感染型的乙型肝炎病毒基因组为部分双链环状DNA，复制型的HBV基因组共价闭合环状DNA慢性HBV感染的进展过程多变，从非活动性病毒携带到严重的活动性肝炎；其中约15%~25%的病人最终导致失代偿性肝硬化、肝细胞癌。

The shen shuai ning capsule combined with zymolysis cordyceps sinensis powder is more effective to decrease lipid and increase Alb in serum. There is a benefit for improve renal function, regulate decompensate and delay the progression of CRF.

肾衰宁胶囊联合发酵虫草菌粉制剂百令胶囊更能有效降低血脂、升高血清白蛋白，对改善肾功能、调节代谢紊乱、延缓CRF进展有较好的作用。

Objective: Chronic renal failure is damage to kidney which is caused by various kinds of idiopathic or successive renal disease. Half-backed renal function leads to a series of clinical symptoms which are caused by decompensate. The renal pathological changes develops slowly but it is one-way and irrecoverable. It evolves as terminal renal disease at last. The pathogenesis of CRF can be unpuzzled with the theory of Chinese medical that it is correlated with asthenia, turbid, and stagnancy.

目的： 慢性肾功能衰竭是由各种原发或继发性肾脏疾患导致肾单位破坏，肾脏功能发生障碍引起的一系列症状和代谢紊乱，虽进展缓慢，但其病程单向不可逆，而且在病程某一阶段呈进行性发展或加重，最终发展为终末期肾病。
