  • Factors of surgical difficulty and complications associated with closure of temporary ileostomy in patients with rectal cancer

    Objective To investigate factors for surgical difficulty and complications following closure of temporary ileostomy for rectal cancer. Methods The clinical data of 103 patients with low rectal cancer treated with closure of temporary ileostomy from January 2014 to July 2017 in the Northern Theater Command General Hospital were retrospectively analyzed. The associated factors of surgical difficulty and postoperative complications were identified by the univariate and multivariate logistic regression analyses. Results In this study, there were 11 (10.7%) patients with surgical difficulty (operation time >100 min) in the 103 patients. The multivariate logistic regression analysis showed that the history of previous abdominal surgery [OR=5.272, 95% CI (1.325, 20.977), P=0.018] and minimally invasive surgery [OR=0.166, 95% CI (0.037, 0.758), P=0.020] were the independent influencing factors of the difficulty of surgery. The complications following closure of temporary ileostomy included 16 (15.5%) patients with the incision infection, 5 (4.9%) patients with the intestinal obstruction, and 3 patients with the pulmonary infection (2.9%). The multivariate logistic regression analysis showed that the diabetes [OR=4.855, 95% CI (1.133, 20.804), P=0.033], operation time >100 min [OR=11.914, 95% CI (2.247, 63.171), P=0.004], and peristomal dermatitis [OR=18.814, 95% CI (3.978, 88.988), P<0.001] were the independent influencing factors for the incision infection. Conclusions History of previous abdominal surgery is main cause for difficulty of surgery and minimally invasive surgery can reduce difficulty of surgery. Diabetes mellitus, longer operation time, and peristomal dermatitis are main causes of postoperative incision infection.

  • Role of Protease-Activated Receptor-2 Activation on The Expression of VEGF mRNA and Its Protein in MKN28 Gastric Cancer Cells

    ObjectiveTo investigate the role of protease-activated receptor-2 (PAR-2) activation on the expression of vascular endothelial growth factor (VEGF) in MKN28 gastric cancer cells. Methods①MKN28 cells were treated with increased concentrations of trypsin (0, 0.1, 1.0, 10.0, and 100.0 nmol/L respectively) for 6 hours, or treated with 10.0 nmol/L trypsin for 3, 6, 12, and 24 hours (blank control group was treated with PBS) respectively, then the expression levels of VEGF mRNA and its protein in MKN28 cells were detected by real-time reverse transcription polymerase chain reaction (qRT-PCR) and Western bolt method, with the concentration of VEGF protein in broth was detected by enzyme linked immunosorbent assay (ELISA) method.②MKN28 cells were divided into blank control group (treated with PBS), trypsin group, trypsin+PD98059 group, trypsin+SB203580 group, PD98059 group, and SB203580 group, then the expression levels of VEGF mRNA and its protein in MKN28 cells were detected by qRT-PCR method and Western bolt method respectively. Results①The effect of different concentration of trypsin. Compared with blank control group, the expression levels of VEGF mRNA and its protein in 0.1, 1.0, 10.0, and 100.0 nmol/L group were higher (P < 0.05); compared with 0.1 nmol/L group, the expression levels of VEGF mRNA and its protein in 1.0, 10.0, and 100.0 nmol/L group were higher (P < 0.05); compared with 1.0 nmol/L group, the expression levels of VEGF mRNA and its protein in 10.0 and 100.0 nmol/L group were higher (P < 0.05); but there was no significant difference between 10.0 nmol/L and 100.0 nmol/L group (P > 0.05). The broth concentration of VEGF protein in blank control group, 0.1, 1.0, 10.0, and 100.0 nmol/L group crept upward (P < 0.05).②The effect of different treated time of 10.0 nmol/L trypsin. The expression levels of VEGF mRNA in blank control group, 3, 6, 12, and 24 hours group crept upward, and there was significant difference between any 2 groups (P < 0.05). But the expression of VEGF protein was not similar with VEGF mRNA. Compared with blank control group, the expression levels of VEGF protein in 3, 6, 12, and 24 hours group were higher (P < 0.05); compared with 3 hours group, the expression levels of VEGF protein in 6, 12, and 24 hours group were higher (P < 0.05); but there was no significant difference among 6, 12, and 24 hours group (P > 0.05). The broth concentration of VEGF protein in blank control group, 3, 6, 12, and 24 hours group crept upward, and there was significant difference between any 2 groups (P < 0.05).③The effect of extracellular regulated protein kinase (ERK) inhibitor (PD98059) and p38 inhibitor (SB203580). The expression levels of VEGF mRNA and its protein in trypsin group were all higher than corresponding indexes of blank control group, trypsin+PD98059 group, trypsin+SB203580 group, PD98059 group, and SB203580 group (P < 0.01), but there was no significant difference among blank control group, trypsin+PD98059 group, trypsin+SB203580 group, PD98059 group, and SB203580 group (P > 0.05). ConclusionActivation of PAR-2 can induce the expressions of VEGF mRNA and its protein in MKN28 gastric cancer cells, that is mediated by ERK1/2-and p38-dependent pathway.
