[Clinic analysis of repeat prostatectomy after transurethral prostatectomy for benign prostatic hyperplasia].

Objective: To analyze the incidence rate of repeat transurethral prostatectomy (TURP) and its probable causes after TURP for benign prostatic hyperplasia (BHP).

Methods: A retrospective study was conducted to summarize the cases who received repeat transurethral resection of prostate after TURP for benign prostatic hyperplasia in recent 20 years. The data were compared with the data of the cases who just received once TURP for BPH.

[Clinical significance of RANTES and MIP-1 alpha in acute rejection episode in kidney transplantation].

Objective: To discuss the correlation between acute rejection episodes and expression of regulated upon activation normal T cell expressed and secreted (RANTES) and macrophage inflammatory protein-1 alpha (MIP-1 alpha) gene following kidney transplantation.

Methods: A total of 76 kidney biopsies (episode biopsy) were performed on both 57 patients with allograft dysfunction following transplantation and 19 patients without rejection, and the latter were served as controls. All acute rejections were confirmed by histological examination.

[Adrenal incidentalomas: report of 126 cases].

Objective: To evaluate the diagnosis and treatment of adrenal incidentalomas.

Methods: One hundred and twenty-six patients were analyzed, in which 98 patients underwent operation.

Results: Of all types of the adrenal incidentalomas, 52 (41.

[Expression of urotensin II mRNA in normal adrenal medulla and pheochromocytoma tissues].

Objective: To investigate the expression of human urotensin II (UII) mRNA in normal adrenal medulla and pheochromocytoma tissues.

Methods: The total RNA of normal adrenal medulla from 9 males who died of accidents and the total RNA of pheochromocytoma tissues resected from 19 patients were extracted. The expression of UII mRNA was studied by reverse transcription-polymerase chain reaction (RT-PCR).

[Telomerase expression in various lesions of adrenal cortex].

Objective: To investigate the expression of telomerase in various lesions of adrenal cortex.

Methods: By autoradiography-based telomeric repeat amplification protocol, telomerase expression was detected in 36 samples of adrenocortical lesions, including 29 cases adrenocortical adenoma (8 Cushing's syndrome, 17 aldosteronism and 4 nonfunctional adenomas), 5 cases of hyperplasia of adrenal cortex (presented with Chushing' syndrome), 2 cases adrenocortical carcinoma, and 4 samples of normal adrenal cortex.

Results: Of the 40 samples, 2 cases of adrenocortical carcinomas had telomerase expression, and the others had no telomerase expression detected.

[A clinical analysis of 103 cases of adrenal incidentaloma].

Objective: To improve the diagnosis and treatment of adrenal incidentaloma (AI).

Methods: Retrospective analysis of 103 AI patients in PUMC Hospital from 1994 to 2002.

Results: Of the 103 cases (43 men and 60 women), most patients were 40-60 years old.
