肾病综合征为每日蛋白尿超过3.5g/1.73m~2体表面积。肾性蛋白尿的后果不取决于基础疾病,而是常伴有水肿形成、钠潴留、高脂蛋白血症、高血栓危险性和易感染倾向。肾性蛋白尿的产生是由于肾小球滤过膜异常所致。该膜由一具有高度选择性的上有多个细孔的膜和一道电子屏障(带多价负离子的葡糖胺多糖)组成。肾小球滤过障碍病因学上在肾病综合征的一种表现形式为局灶节段性肾小球硬化,证实了一种循环的、可能由淋巴细胞产生的因 Nephrotic syndrome is daily proteinuria over 3.5g / 1.73m ~ 2 body surface area. The consequences of renal proteinuria do not depend on underlying disease, but are often accompanied by edema, sodium retention, hyperlipoproteinemia, high thrombotic risk and predisposition to infection. Renal proteinuria is due to abnormal glomerular filtration membrane. The membrane consists of a highly selective membrane with multiple pores and an electronic barrier (polyglucosamine with polyvalent anion). Glomerular filtration disorders etiologically, a form of nephrotic syndrome that is focal segmental glomerulosclerosis, confirms a circulatory, possibly lymphopoietic
