ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mechanism of "Jianpi Qinghua Decoction" (JQD) on renal fibrosis by observing the impact of JQD on serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and kidney tumor necrosis factor-Α (TNF-Α) expressions in focal segmental glomerulosclerosis rats induced by nephrectomy combined with adriamycin.</p><p><b>METHODS</b>Totally 56 male SD rats were divided into normal group, sham operation group, model group, JQD group, Yiqi Jianpi group, Qingre Huashi group, and Niaoduqing group (all n=8). The model of focal segmental glomerulosclerosis was established by the unilateral nephrectomy and the injection of adriamycin in caudal vein of rat at a dose of 3 mg/kg in the latter 5 groups. JQD, the disassembled prescription of Jianpi Qinghua Decoction (Yiqi Jianpi Decoction and Qingre Huashi Decoction), and Niaoduqing Capsule were administered separately for 8 weeks. The serum TC, TG, LDL, and VLDL levels and the expression of Kidney TNF-Α were determined.</p><p><b>RESULTS</b>Compared with normal group and sham operation group, the serum TC, TG, LDL, and VLDL levels and the kidney TNF-Α expression in the model group were significantly higher (all P<0.01). Compared with the model group, the JQD group, Qingre Huashi group, and Niaoduqing group had significantly lower serum TC, TG, LDL, and VLDL levels and kidney TNF-Α expression (all P<0.01). Compared with the model group, the Yiqi Jianpi group had significantly lower serum TC ,TG, and VLDL levels (all P<0.01), while the serum LDL level and kidney TNF-Α expression remained unchanged (all P>0.05).</p><p><b>CONCLUSIONS</b>JQD can regulate serum lipids and lower the TNF-Α expression in kidney tissue and thus improve the renal inflammation and relieve renal fibrosis. The heat-clearing and dampness-removing herbs in the prescription play a central role in fighting against renal fibrosis.</p>
