ABSTRACT
Objective To evaluate the efficacy and safety of Sanqi Granules (SG) for the treatment of chronic glomerulonephritis(CGN).Methods A prospective randomized controlled trial was carried out in 60 CGN patients with qi deficiency and blood stasis syndrome.The included patients were assigned into SG group,losartan group,and SG plus losartan group,20 cases in each group.The course of intervention was 24 weeks.Before and after treatment,24-hour urine protein quantity,serum creatinine (SCr),estimated glomerular filtration rate (eGFR) and the scores of traditional Chinese medical syndromes were observed.The clinical efficacy of Chinese medicine and western medicine,and the safety was evaluated after treatment.Results (1) After treatment for 12 and 24 weeks,the scores of traditional Chinese medical syndromes in the three groups were markedly improved (P ＜ 0.05),and the improvement in SG group and SG plus losartan group was superior to that in losartan group (P ＜ 0.05).(2) After treatment for 24 weeks,24-hour urine protein quantity in losartan group was significantly decreased (P ＜0.05),while SG group and SG plus losartan group only showed a decreasing trend(P ＞ 0.05).(3) After treatment for 24 weeks,renal function indexes of SCr and eGFR in SG group and SG plus losartan group were improved to some degrees,and the difference of eGFR in SG group was significant (P ＜ 0.05 compared with that before treatment),while the renal function injury in losartan group showed a deteriorative trend.SG group and SG plus losartan group had better effect on improving SCr and eGFR than losartan group (P ＜ 0.05).(4) After treatment for 24 weeks,the total effective rate of Chinese medicine in losartan group,SG group,SG plus losartan group was 50.00％,90.00％,84.21％,and the total effective rate of western medicine was 88.89％,75.00％,63.16％,respectively.SG group and SG plus losartan group had better clinical efficacy of Chinese medicine than losartan group (P ＜ 0.05),while the difference of clinical efficacy of western medicine among the three groups was insignificant (P ＞ 0.05).(5) During the follow-up,no severe adverse events were shown in the three groups.Conclusion SG exert certain therapeutic effect on improving the scores of traditional Chinese medical syndromes and protecting renal function,while have no obvious effect on decreasing urine protein.
ABSTRACT
Objective To construct the nuclear receptor-related factor 1 ( Nurr1) specific short-hairpin RNA (shRNA) expressing vectors and study their effects on the expression of endogenous genes in MN9D dopaminergic cell lines. Methods Two RNAi recombinant plasmids (named pSC-N1 and pSC-N2) targeting at Nurrl gene were constructed. The purified plasmids were identified by DNA sequencing. After being transfected into MN9D dopaminergic cell lines with Lipofectamine?2000, the silencing effects of Nurrl shRNA expressing vectors on the expression of Nurrl mRNA and protein in MN9D cells were detected using real time fluorescence quantitative PCR and Western blot Results DNA sequencing confirmed that the Nurrl shRNA expressing vectors were constructed successfully. Nurrl mRNA expression in MN9D cells was specifically suppressed after the transfection of pSC-Nl and pSC-N2 by 62.3% and 45.6% respectively. Moreover, the expression of Nurrl protein was significantly suppressed by 57.4% and 72. 0% respectively. The control vectors had no silencing effect Conclusions The vectors pSC-Nl and pSC-N2 have been successfully constructed and can specifically suppress the expression of Nurrl mRNA and protein. Nurrl specific shRNA expressing vector may provide a novel applicable strategy for the study of the function of the genes associated with Parkinson disease and the development of dopaminergic neuron.
