Objective To investigate the correlation between asymmetric dimethylarginine (ADMA) and endothelial dysfunction in patients with type 2 diabetic nephropathy.Methods The 81 patients with type 2 diabetic nephropathy were selected.According to the urinary albumin excretion rate (UAER),the patients were divided into micro-albuminuria group (DN1 group,UAER 21-199 mg/24 h,38 cases) and macro-albuminuria group (DN2 group,UAER ≥ 200 mg/24 h,43 cases).The 20 healthy people were defined as control group.Intimal-media thickness and endothelial dysfunction of the radial artery of right forearm were detected by color Doppler ultrasound.The serum level of ADMA was determined by enzyme-linked immunosorbent assay.Results There was no significant difference in radial artery inner diameter intimal-media thickness among the 3 groups (P ＞ 0.05).The Endothelial dependent diastolic function (EDD) and endothelial independent diastolic function (EID) in DN1 group and DN2 group were significantly lower than those in control group [(10.45 ± 2.58)％ and (7.56 ± 2.17)％ vs.(15.72 ± 3.05)％,(15.42 ± 2.71)％ and (15.37 ± 2.92)％ vs.(19.31 ± 3.76)％,P ＜ 0.05],and the EDD in DN2 group was significantly lower than that in DN1 group (P＜ 0.05).The serum ADMA in DN1 group and DN2 group was significantly higher than that in control group [(0.63 ± 0.08) and (0.92 ± 0.12) μ mol/L vs.(0.39 ± 0.05)μmol/L,P ＜0.05],and in DN2 group it was significantly higher than that in DN1 group (P ＜0.05).In patients with type 2 diabetic nephropathy,the serum ADMA and EDD had negative correlation (r =-0.81,P =0.020),but the serum ADMA and C reactive protein had positive correlation (r =0.75,P =0.034).Conclusions The serum level of ADMA is significantly increased in patients with type 2 diabetic nephropathy.There is a close correlation between ADMA and endothelial dysfunction of artery.

Objective To observe the clinical characteristics and prognosis of primary nephrotic syndrome (PNS) in the elderly. Methods The clinical and pathological features of 52 elderly patients with PNS and 64 non-elderly patients with PNS were retrospectively analyzed and compared.The elderly patients with PNS received routine treatment:oral corticosteroids prednisone 1mg·kg-1 ·d-1.After 8 weeks maintenance treatment,if symptoms were alleviated,the prednisone dose was gradually reduced to a maintenance dose, then was stopped gradually. If symptoms were not alleviated, the cyclophosphamide or cyclosporine, mycophenolate mofetil was added. Results There were significant differences in the numbers of patients complicated with hypertension, infection,chronic renal insufficiency and hematuria between the elderly group and non-elderly group (P＜0. 05＝.But there were no significant differences in the level of blood albumin, quantitative measurement of 24 hours urinary protein and incidence rate of acute renal insufficiency between the two groups (P＞0.05). The major pathological types of PNS in the elderly were membranous nephropathy (46.2 %),IgA nephropathy (23. 1 %) and focal segmental glomerulosclerosis ( 11.5 %), respectively. And the major pathological types of PNS in non-elderly group were mesangial proliferative glomerulonephritis (32.8%), IgA nephropathy ( 25.0% ) and minimal change nephropathy ( 20. 3 %), respectively.Complete remission after treatment was found in 31 patients(59.6%), partial remission in 18 cases and inefficacy in 3 cases. Conclusions The major clinicopathological type of PNS in the elderly is membranous nephropathy and should be treated using corticosteroids and immunosuppressive agents,with different effects in different pathological types.

The further purpose is to supply innovative and practical research thought and method for scientifically confirming the daily administration times of CMM and enhancing its clinical efficacy.

OBJECTIVE: To investigate the in-vitro release behavior of venetoclax preparations, the pharmacokinetic processes and the correlations between in-vitro release and in-vivo absorption of venetoclax in Beagle dogs. METHODS: The dissolution curves of venetoclax preparations in different dissolution media were studied. HPLC method was established for the determination of venetoclax in Beagle dogs, and the pharmacokinetics were studied for commercial venetoclax tablets in Beagle dogs under fed and fasted states.The IVIVC study was carried out by linear regression of cumulative in-vitro drug release and in-vivo absorption accumulation percentage data. RESULTS: The in-vitro release behavior among venetoclax formulation in 4 dissolution media were significant difference. The simple, accurate and rapid analysis method for venetoclax blood samples was established. The fed group and the fasted group AUC0→∞ were (32.38±5.87) and (27.70±6.32) mg·h·L-1, the concentration of peak were (4.04±0.78) and (3.72 ±0.69) μg·mL-1, the peak time were (6.01±1.04) and (4.27±0.92) h, respectively, and there was obvious difference (P<0.05) in AUC0→∞ and the peak time between two group. Percentage of in-vivo absorption was in good agreement with in-vitro release in pH 6.8 0.2%SDS media. CONCLUSION: The study shows that food could improve the bioavailability of venetoclax formulation; 0.2%SDS pH 6.8 media (paddle, 75 r·min-1) is the in-vivo release of venetoclax associated with the in-vitro release condition.
