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.

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 investigate the effect of Kanglaite injection (KLT) on immunological function of rat models with Lewis lung carcinoma. Methods Forty C57BL/6 mice were used to establish Lewis lung carcinoma models and divided randomly into the high dose(25 mL/kg), middle dose (12.5 mL/kg) and low dose (6.25 mL/kg) of KLT groups and model group(n=10). The mice in the KLT groups were sacrificed after injecting corresponding dose of KLT with intraperitoneal injection for 14 d. No treatment was performed on the rats in model group. The body weight, tumor and spleen weight was weighed, then the ratio of tumor restriction and the index of spleen was calculated. MTT colorimetric method and ELISA were used to detected activity of T cell proliferation and expression of IL-2 in spleen. The expression of NF-κB and IκBα protein was detected by Western blot. Results The ratio of tumor restriction in the high, middle, low dose of KLT groups decreased gradually. The indexes of spleen of the high and middle dose of KLT groups were higher than those in the model group (P<0.05 or P<0.01).Compared with the model group, the activity of T cell proliferation in the high, middle, low dose of KLT groups and the expression of IL-2 in the high and middle dose of KLT groups was increased significantly (P<0.05 or P<0.01). The expression of NF-κB protein in the nuclei of high, middle, low dose of KLT groups increased dose-dependently, and the expression of NF-κB and IκBα protein in the cytoplasm decreased dose-dependently. ConclusionKLT could enhance immunological function by effecting T cell proliferation, expression of IL-2, NF-κB and IκBα, while restricting tumor growth in Lewis lung carcinoma models.
