Objective To investigate the effect of Tongmai oral liquid on the early diabetic nephropathy. Methods Diabetic nephropathy rats were induced by excision of the right kidney and a single intraperitoneal injection of streptozotocin (STZ). Forty male Wistar rats were divided randomly into 3 groups:Tongmai group, nephrotic model group, and normal group. At the end of the 8th week, the rats general states and some parameters such as kidney hypertrophy index, 24 h urine volume, blood glucose, 24 h urinary microalbumin (24 h UMA), renal function [serum creatinine (Cr), blood urea nitrogen (BUN)], serum lipid, and the change of nephritic pathologic lesion were measured. Result Compared with the model group, general states in Tongmai group were improved, there was a considerable increase on body weight (P

Objective: To observe the therapeutic effects of effective compounds which were extracted from TongMai. Methods: SD rats experimential model with MsPGN were induced by subcutaneously injection rabbit anti-rat thymocyte serum(ATS) and forced swim. The rats were respectively ig with different dose(1.2,0.6,0.3 g'kg-1) of effective compound of TongMai for 4 weeks. Then the proliferative degree of mesangium was examined by HE stain, PAS stain and immunfluorescent respectively. Mesagium area proportion in glomerular capillaries area was calculated using image analyzing system. The expression of PCNA in the glomeruli was examined by immunohis to chemistry. Results: The effective compounds of TongMai can control the hyperplasia of the glomemlar mesangial cells (GMG)and the mainifold of the mesangial matrix, and prevent the deposit of IgG in mesangium. The proportions in glomerular capillaries area in model control group were significantly higher than that in the treatment groups; The express of proliferative cell nuclear antigen (PCNA) were ascended either. Conclusion: The effective compound of TongMai can improve the damage s of pathology in glomerular.

The mechanism of Tongmai Oral Liquid (TOL) for chronic nephritis rat model with Qi-deficiency and blood-stasis syndrome was studied.The model was established by adding Qi-deficiency and blood-stasis syndrome to the chronic nephritis rats. The experimental rats were randomly allocated to 5 groups: Group A (treated with high dosage of TOL), Group B (treated with low dosage of TOL), Group C (treated with Jinshuibao), Group D (model control group) and Group E (normal control group). After 4 weeks of treatment, general health state, biochemical indexes including T lymphocyte subgroup and blood rheology, and pathological damage of kidney tissue were much improved in Group A than Group B and Group C. It is indicated that TOL can improve the renal function and delay the occurrence of glomerular arteriosclerosis in rats by reinforcing Qi, activating blood flow, regulating immune function, lessening the hypercoagulative state and reducing renal damage.

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.
