Poor early urinary outcomes after laparoscopy were reported in studies comparing laparoscopic versus open rectal cancer surgery. One possible explanation was that these studies might include a number of patients on the laparoscopic surgeons' learning curve. This study aims to evaluate whether the learning curve of laparoscopic rectal cancer surgery influences early postoperative urinary dysfunction.

Objective: To investigate the risk factors for the prognosis in patients with gastric cancer undergoing surgery.

Methods: Clinical data of 1031 cases who underwent gastric cancer resection from January 2003 to December 2007 were studied using univariable analysis and multivariable regression analysis.

Results: In 1031 cases,95 (9.

Objective: To investigate the correlation between major histocompatibility complex (MHC) class I chain-related gene A (MICA) gene alleles matching rates and graft rejection in small intestine, liver and kidney transplantation.

Methods: Genome DNA were extracted from blood samples or pathological sections collected from donors and recipients of living-related transplantation, included 4 cases of small bowel transplantation, 5 cases of liver transplantation and 6 cases of kidney transplantation. The correlation between MICA alleles matching rates and acute graft rejection was analyzed following 13 MICA alleles determination by polymerase chain reaction based on sequence-specific primers (PCR-SSP).

Objective: To determine the expression of new candidate tumor suppressor gene N-Myc downstream-regulated gene 2(Ndrg2) in colorectal cancer with different differentiation, and analyze its clinical significance.

Methods: Specimens of 50 colorectal cancer patients with different differentiation were collected. Immunohistochemistry and Western blot were used to examine the expression of Ndrg2.

Background: The S100 protein family comprises 22 members whose protein sequences encompass at least one EF-hand Ca2+ binding motif. They were involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. However, the expression status of S100 family members in gastric cancer was not known yet.

Objective: To analyze the expression level of candidate tumor suppressor gene N-Myc downstream-regulated gene 2 (NDRG2) in human colon cancer.

Methods: Thirty samples of colon cancer tissues with matched normal colon tissues were collected. The NDRG2 mRNA level was detected by semi-quantitive RT-PCR and the NDRG2 protein level was examined by Western blot and immunohistochemistry.

RANTES (or regulated upon activation, normal T cell expressed and secreted) belongs to the rapidly growing chemokine family. It is mainly produced by T cells, epithelial cells, monocytes, fibroblasts, and mesanglial cells. Increased RANTES expression has been associated with a wide range of inflammatory disorders and pathologies.

Objective: To construct a recombinant adenovirus vector which regulates the expression of rat transforming growth factor beta (TGF-beta1).

Methods: Total RNA was extracted from F344/N rat small intestine pre-treated with Con A to clone TGF-beta1. pTRE-shuttle vector was used as mediator to ligate TGF-beta1 gene and backbone of replication-incompetent adenoviral vector.
