[Expression of Calponin-1 and Transgelin in human uterine smooth muscles in non-labor and labor situation].

Objective: To investigate the expression of Calponin-1 and Transgenlin in the uterine smooth muscles during normal labor on-sets, and to evaluate their effect on initiating the normal labor.

Methods: A total of 14 uterine bodies and lower segments of human pregnancy were divided to a non-labor group (NIL) and a labor group(IL). Immunohistochemical technology and Western blot were used to determine the expression of Calponin-1 and Transgelin in the 2 groups.

[Roles of endothelin and nitrogen monoxide in the adenine-induced acute renal failure models].

Objective: To determine the roles of endothelin (ET) and nitrogen monoxide (NO) in the adenine-induced acute renal failure (ARF) models.

Methods: ARF models were established by feeding adenine in rats. The activity of NO synthase (NOS) in kidneys of rats was tested by NADPH-diaphorase.

[Uroflowmetry and its influence factors in benign prostate hyperplasia patients].

Objective: To determine the relationship between uroflowmetry and age, the course of disease, premicturition volume, transition zone index and proportion of stroma-to-epithelium in benign prostate hyperplasia (BPH) patients.

Methods: Eighty-nine BPH patients in our hospital from 2000 to 2003 were evaluated. With the CMM3 pathology image analysis system, transrectal ultrasound and Dantec 2000 urodynamic instrument, the value of influence factors was determined.
