Protective effect of pioglitazone on kidney injury in diabetic rats.

Objectives: To investigate the protective effect of pioglitazone on kidney injury in diabetic rat model and its mechanisms.

Methods: Forty healthy Sprague Dawley rats were selected and randomly divided into five groups, with 8 rats in each group. Group A served as control group and were administered with sterile citrate buffer (i.

Overexpression of immunoglobulin G prompts cell proliferation and inhibits cell apoptosis in human urothelial carcinoma.

Only B lymphocytes can express immunoglobulins according to the traditional immunological theories, and the expression of immunoglobulin G (IgG) messenger RNA (mRNA) and protein was found in certain human cancer cells recently. However, the expression pattern of IgG and its possible role in human urothelial carcinoma are still elusive. In this study, we investigated the expression of IgG in two human urothelial carcinoma cell lines, T24 and BIU-87, and in 56 cases of clinical urothelial carcinoma tissues.

Effect of collagen on the mechanical properties of hydroxyapatite coatings.

In this study, the mechanical properties of bioactive coatings on Ti6Al4V substrates were investigated using instrumented nanoindentation. The aim was to observe the differences in the mechanical properties before and after immersion in collagen solution. The hydroxyapatite coatings were prepared through two processes: self-assembly in simulated body fluid and a hydrothermal method.

[Urethroplasty with oblique preputial island flap for the treating of hypospadia].

Objective: To Explore the effect of oblique preputial island flap for the treating of hypospadias.

Methods: Fifty-one patients were performed one-stage urethroplasty with oblique preputial island flap to repair hypospadias.

Results: All cases resulted in a good contour of the penis without any redundancy and a normal anatomic position of slit-shaped urethral meatus.
