[Clinicopathological study of primary carcinoid tumor of the testis].

Objective: To study the clinicopathological characteristics, immunohistochemical features and histogenesis of primary testicular carcinoid tumor and its differential diagnosis.

Methods: Light microscopy and immunohistochemical stains were performed in 4 cases of primary testicular carcinoid tumor.

Results: The patients sought care for scrotum mass presented from 2 to 36 years, 2 cases accompanied with tender swelling of the testis.

Vasoactive intestinal peptide inhibits adhesion molecule expression in activated human colon serosal fibroblasts by preventing NF-kappaB activation.

Background: Stricture formation in Crohn's disease (CD) occurs as a result of persistent intestinal inflammatory activation, which leads to enhanced adhesion molecule expression in serosal fibroblasts (SFs). Vasoactive intestinal peptide (VIP) has anti-inflammatory and immunoregulatory properties. Treatment with VIP prevents experimental CD in animal models at the clinical and pathologic levels.

Triptolide suppresses IL-1beta-induced chemokine and stromelysin-1 gene expression in human colonic subepithelial myofibroblasts.

Aim: To examine the inhibitive effects of triptolide on the expression of IL-8, monocyte chemotactic protein (MCP)-1, and matrix metalloproteinases (MMP)-3 in subepithelial myofibroblasts (SEMF) stimulated with IL-1beta.

Methods: SEMF cultures were established from normal colons in patients who underwent gut resection for colorectal carcinoma. Chemokine and MMP-3 expressions were determined by ELISA and RT-PCR.

[BRG1 expression in prostate carcinoma by application of tissue microarray].

Objective: To investigate the expression of gene BRG1 in prostatic intraepithelial neoplasia and adenocarcinoma, and the relationship between gene BRG1 expression and the clinicopathological features of prostate carcinoma.

Methods: Gene BRG1 expression was evaluated in 37 cases of human prostate carcinoma, 13 human prostatic intraepithelial neoplasia (PIN) and 14 human benign prostatic hyperplasia (BPH) by using immunohistochemistry (EnVision method) and tissue microarray.

Results: The positive rates of BRG1 protein were 81.

[Flow cytometry and its application in andrological studies].

As an advanced technology, flow cytometry has its unique advantages in detecting single cells quantitatively and rapidly. So it has been used more and more widely in clinical examination. FCM offers a powerful tool and exciting opportunities for accurately evaluation of semen quality and sperm functions.

[Quality evaluation of three different sperm counting chambers].

Objective: Semen evaluation is the most important laboratory test for assessing male fertility. However, lack of strict quality control (QC) for semen analyses in hospital andrology laboratories makes it difficult and meaningless to compare semen data between different laboratories. This paper reports a comparative study on the accuracy of the Hemacytometer (Qiujing Inc.

Rehabilitation therapy for short bowel syndrome.

Objective: To investigate the effect of rehabilitation therapy for short bowel syndrome on patient nutritional status and intestinal adaptation.

Methods: The rehabilitation therapy included enteral or parenteral nutrition, glutamine, recombinant human growth hormone and rehabilitative diet. From January 1997 to July 2000, twenty - seven patients with short bowel syndrome received the treatment.

[Rehabilitation therapy for short bowel syndrome].

Objective: To investigate the effect of rehabilitation therapy for short bowel syndrome on patients' nutritional status and intestinal adaptation.

Methods: Twenty seven patients with short bowel syndrome with the average age of 38.5 +/- 19.
