[Expressions of NOS isoforms in the cavernous tissues of diabetic rat models].

Objective: To investigate the mechanism of diabetic erectile dysfunction (ED) and find new methods for its treatment by detecting the changes in nitric oxide synthase (NOS) isoforms and erectile function of diabetic rats and observing the effects of insulin and alpha-lipoic acid (LA) on it.

Methods: Fifty male Sprague-Dawley rats were divided into Groups A (normal control, n=10), B (non-intervention diabetes mellitus, n=13), C (insulin intervention diabetes mellitus, n=12), and D (insulin + LA intervention, n=15). And the diabetic models were made by intraperitoneal injection of streptozocin (STZ).

[The results of surgery on HIV carriers with urinary system disease].

Objective: To approach characteristics of performing operation on HIV carriers with urinary system diseases.

Methods: To summarize author's experiences of surgery on 41 HIV carriers suffering urinary system diseases abroad from April 1996 to May 2004.

Results: The 41 HIV carriers received HAART and were performed with corresponding operations, followed up from 4 to 30 months post-operatively.

[Expression of nerve growth factor in cavernous tissue and its effects on the treatment of rats with diabetic erectile dysfunction].

Objective: To investigate the content of nerve growth factor (NGF) in penis of rats with diabetic erectile dysfunction (DED) and apply rhNGF to treat the DED rat model to study the pathogenesis mechanism of DED and treatment effects by NGF for DED rat model.

Methods: Fifty adult male SD rats were randomly selected to make up diabetic models. After 8 weeks, the mRNA and protein levels of NGF in rat penis were detected.
