AIM:To investigate the effects of high concentration of glucose on the expressions of serum and glucocorticoid induced protein kinase 1 (SGK1) and fibronectin in human podocytes and detect the production of fibronectin in human podocytes transfected with active and mutant forms of SGK1.METHODS: The expressions of SGK1 and fibronectin in human podocytes exposed in high glucose for 24 h were detected by using Western blotting. Human podocytes were transfected with three kinds of plasmid: pIRES2-EGFP-SGK1SD (SGK1-active plasmid), pIRES2-EGFP-SGK1KN (SGK1-mutant plasmid) and pIRES2-EGFP (empty vector plasmide). The synthesis levels of fibronectin were detected by immunofluorescence.RESULTS: The expression of SGK1 in normal human podocytes was observed and the expression level was up-regulated in podocytes exposed to high glucose for 24 h (50?4 vs 35?3), parallelly with the high expression of fibronectin (19?4 vs 12?2). The secretion of fibronectin was increased obviously in SGK1-active plasmid (SGK1SD) transfected podocytes compared with the vector transfected podocytes. Whereas, the fibronectin level was decreased significantly but not completely abolished in SGK1-mutant plasmid (SGK1KN) transfected podocytes, compared with SGK1SD transfected podocytes. CONCLUSION: SGK1 may be involved in the synthesis of fibronectin in human podocytes induced by high glucose and play a critical role in the activation of human podocytes during early stage of diabetic nephropathy.

BACKGROUND: Multiwaled carbon nanotubes can accelerate the proliferation and differentiation of osteoblasts, and exert a therapeutic effect on steroid-induced necrosis of femoral head (SNFH). OBJECTIVE:To investigate the function of multiwaled carbon nanotubes in the establishment of a rabbit model of SNFH. METHODS:Thirty-six New Zealand white rabbits were divided randomly into three groups. In treatment group, 16 rabbits were given intraglutealy injection of dexamethasone (2.5 mg/kg) every day and injection of 1 mL liquor of multiwaled carbon nanotubes (0.1 g/L) into the bilateral femur medulary space every week. In model group, 16 rabbits were given intraglutealy injection of dexamethasone (2.5 mg/kg) every day and injection of 1 mL normal saline into the bilateral femur medulary space every week. In control group, four rabbits were given intraglutealy injection of 2 mL normal saline every day and injection of 1 mL normal saline into the bilateral femur medulary space every week. RESULTS AND CONCLUSION: Four weeks after hormone injection, the trabeculae began to exhibit a smal amount of thinner fractures, an accumulation of fatty tissue in the bone marrow were obvious, bone marrow fat cels became bigger and microvascular thrombosis appeared in the model group, while there was no positive histopathological manifestation in the treatment group. This indicates that the multiwaled carbon nanotubes can extenuate pathological damage to the femoral head to a certain extent.

Objective To assess the surgical treatment of iatrogenic biliary strictures. Methods The clinical data of 235 patients with iatrogenic biliary injuries and strictures who had been admitted to our hospital from January 1989 to December 2006 were reviewed retrospectively. Cholangio-jejunal Roux-en-Y anastomosis (n=182), surgical repair with pediele flap of autogenous tissues (n=34), end-to-end choledocho-choledo-chostomy (n= 12), common bile duct incision and figuration +T-tube drainage ( n =6) and liver transplanta-tion ( n = 1 ) were applied to the patients. Results A total of 189 patients were followed up for 1 to 10 years. The total excellent and good rate was 94.7% (179/189). The recurrence rate of the biliary stricture was 5.3% (10/189), and the main cause of which were biliary cirrhosis, selerosing cholangitis and calculus. One patient with severe biliary cirrhosis and portal hypertension died of liver failure postoperatively. Conclusions The cholangio-jejunal Roux-en-Y anastomosis is a reliable and effective method. Surgical repair of the bile duet with pedicle flap of autogenous tissues could preserve the function of the sphincter of Oddi, but the long-term effect needs further investigation. Biliary stent is not usually necessary to install. Liver transplantation is efficient for the patients with end stage of biliary diseases caused by biliary stricture.
