[Effect of Yufeining on induced sputum interleukin-8 in patients with chronic obstructive pulmonary disease at the stable phase].

Objective: To evaluate the effect of Yufeining, a traditional Chinese medicine, on induced sputum interleukin-8 (IL-8) in patients with chronic obstructive pulmonary disease (COPD) at the stable phase.

Methods: Thirty-six patients with COPD were divided into trial group (18 cases) and control group (18 cases) randomly. The trial group was treated with Yufeining pills taken orally for half a year; the control group was not given any medicine.

[Examination and significance of semenial prostate specific antigen in infertile patients].

Objective: To investigate the significance of prostate specific antigen (PSA) examination in seminal plasma of infertile patients.

Methods: Eighty-five infertile patients were collected randomly. The level of PSA in seminal plasma was detected by ELISA method.

[Relationship between genetic polymorphisms of metabolizing enzymes and prostate cancer].

Objectives: To study the possible relationship between CYP1A1, NAT2 genetic polymorphisms and the susceptibility of prostate cancer.

Methods: Forty-eight patients with prostate cancer and 112 healthy cases were selected as the control randomly. NAT2 and CYP1A1 gene polymorphisms were analysed with the methods of PCR-RFLP, ASA and real-time fluorescence Light-Cycler.
