Objective To study molecular target of total flavonoid in Ligustrum Lucidum Ait(TFL) on lipometabolism regulation of HepG2 cell.Methods Treatment doses of total flavonoid in Ligustrum Lucidum Ait were determined by MTT and LDH.The expression of lipoprotein lipase(LPL),3-hydroxy-3-methylglutary-coenzyme A redutasein(HMGCR)and peroxisome proliferator-actived receptorsα(PPARα)mRNA of HepG2 cell were determined by reversed transcription polymerase chain reaction(RT-PCR).Results Increased expression of LPL mRNA and PPARαmRNA with TFL(10-6～10-4g/ml)were found in HepG2 cells after treated with TFL(10-5g/ml),but decreased expression of HMGCR mRNA was found after treated with TFL(10-5,10-4 g/ml).Conclusion The potential mechanisms of total flavonoid in Ligustrum Lucidum Ait's hypolipidmic effects may be with its functions of regulating lipoprotein degradation through PPARα-LPL pathway,or regulating steroid biosynthesis by reducing HMGCR.

Objective To investigate the clinic efficacy of Qiwei Liaoshang Powder on empyrosis. Methods 176inpatients suffering empyrosis were included in our study. A prospective randomized study was adopted to evaluate the efficacy of Qiwei Liaoshang Powder, while exposure therapy of San Huang Cream was taken as control. Bacteria culture,healing time, and pain of wounds were compared. Results Qiwei Liaoshang Powder had less healing time, pain and infection rate than San Huang Cream. Conclusion Qiwei Liaoshang Powder is effective to treat empyrosis.

Objective To evaluate the efficacy of Yangsheng-Yishen decoction combined with irbesartan in the treatment of early diabetic nephropathy (DN).Methods A total of 95 patients with early DN who met the inclusion criteria were randomly divided into control group (47 cases) and treatment group (48 cases).The control group was treated with irbesartan,while the treatment group was given Yangsheng-Yishen decoction on the basis of the control group.The two groups were treated for 6 months.The FBG,HbAlc,urinary albumin excretion rate (UAER),Scr,TG,TC,LDL-C and HDL-C were detected by automatic biochemical analyzer.The level of vascular endothelial growth factor (VEGF),platelet derived growth factor (PDGF),tumor necrosis TNF-α and transforming growth TGF-β were measured by elisa assay,and the clinical efficacy was evaluated.Results After treatment,the levels of FBG,HbAlc,UAER and SCr in the treatment group was significantly lower than those in the control group (t=3.886,4.056,9.346,8.806,all P＜0.01).After treatment,the serum TG,TC and LDL-C of the treatment group were significantly lower than those of the control group (t=8.294,12.800,6.153,all P＜0.001),and HDL-C was significantly higher than that of the control group (t=4.293,P＜0.01).The levels of serum VEGF,PDGF,TNF-α and TGF-β in the treatment group was significantly lower than those in the control group (t=13.585,11.613,10.774,10.490 respectively,all P＜0.01).Conclusions The Yangsheng-Yishen decoction combined with irbesartan can reduce blood sugar,blood lipid and urinary protein level in early DN patients,improve renal function.
