Objective To assess the effects of hypothermia induced by 4 ℃ normal saline (NS) on biochemical function, enzymology and morphology of liver in swine after the success of cardiopulmonary resuscitation (CPR) for cardiac arrest(CA). Method The swine were resuscitated with standard CPR 4 minutes after ventricular fibrillation(VF) ,and the survived swine were randomly(random number) divided into two groups. In hypothermia(LT) group (n = 5), swine were treated with continuous infusion of 4 ℃ NS at the speed of 1.33 mL/(kg·min) for 22 min, and then slow the speed to 10 mL/(kg·h) for 4 h. In normothermia (NT) group ( n= 5) swine were treated with the infusion of NS with room temperature instead of cryogenic NS at the same speed as the LT group. The hemodynamics and the changes of blood gas were monitored until 4 h after restoration of spontaneous circulation (ROSC), and blood samples were taken to detect serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) before VFand 10 min, 2 h and 4 h after ROSC. All swine were sacrificed 24 hours after ROSC, and their liver tissues were taken away for detecting Na+ -K + -ATP enzyme and Ca2+ -ATP enzyme as well as the histological changes under both light and electron microscopy. ResultsThe heart rate, MAP, cardiac output(CO) and coronary perfusion pressure(CPP) of swine were stable in LT group ( P ＞ 0.05). The AST, ALT and LDH increased in both groups but less in LT group. The hepatic ATP enzyme activity was much higher in LT group ( P ＜ 0.05). Compared with the NT group, there were less cellularedema,necrosis or inflammatory cells infiltration, and better morphosis of mitochondria of livers found in swine of LT group. Conclusions The continuous administration of 4 ℃ NS after ROSC could quickly lower the core body temperature, and it could keep hemodynamics and oxygen metabolisms stable, protecting the biochemical function,enzymology and morphology of liver in swine after CPR.

This article summarizes 32 cases of the SCI patients suffered from bladder stones.Respects relating to causes,characteristic,diagnosis,treatment and prevention of bladder stones after SCI are discussed in the article.In order to decrease or avoid complication of indwelling urethral catheter,the patients with neuropathic bladder dysfunction are treated by intermittent catheterization.If it is necessary for SCI patients to indwell urethral catheter,we must strengthen management of the catheter and renew a catheter in time(once a week).

ObjectiveTo observe the effect of urethral stent implantation on detrusor-sphincter dyssynergia caused by neurogenic lower urinary tract dysfunction.Methods13 patients with detrusor-sphincter dyssynergia caused by neurogenic lower urinary tract dysfunction were treated with the operation of the urethral stent implantation. Voiding function, renal function, residual urine volume and hytronephrosis were examined before and after the operation to evaluate the effect of this procedure.ResultsAfter operation, 7 patients normally emptied their bladders and 6 patients had urinary incontinence. Urethral stents were removed from 2 patients in this group due to the irritation symptoms, the second implantation was performed in a patient due to the voiding difficulty. The renal function of patients after the operation had a non-significant improvement, but the residual urine volume and hytronephrosis improved significantly.Conclusion Urethral stent implantation can decrease residual urine volume and hytronephrosis in patients with detrusor-sphincter dyssynergia caused by neurogenic lower urinary tract dysfunction.

Objective:To explore the effect and mechanism of miRNA sponge on the epithelial-mesenchymal transition (EMT) of gastric carcinoma cell lines SGC7901. Methods:Synthetic ZEB2 3'UTR plasmid and siRNA targeting ZEB2 were transfected into the SGC7901 cell line by Lipofectamine 2000. Real-time quantitative polymerase chain reaction was performed to evaluate the expres-sion levels of miR-200a/b/c. Finally, the migratory, invasive, and proliferative activities of the gastric carcinoma cells in vitro were ana-lyzed by the scratch test, the Transwell cell invasion, and the cell cloning assay. The expression of the target protein was detected by Western blot. Results:Compared with the control group, the expressions of miR-200a/b/c significantly decreased, and their migration, invasion, and proliferation capabilities were considerably higher after they were transfected with ZEB2 3'UTR. Although the expres-sions of miR-200a/b/c significantly increased, the migratory, invasive, and proliferative activities of SGC7901 cells also degraded after they were transfected with siRNA targeting ZEB2. The expression of ZEB2 increased, and that of E-cadherin decreased at the protein level after they were transfected with ZEB2 3'UTR. The protein expression of Vimentin in SGC7901 cells significantly increased. The indicators show the opposite trend when cells were transfected with siZEB2, and the differences between the control and mutation groups were insignificant. Conclusion:ZEB2 3'UTR can regulate EMT course by regulating the miR-200a/b/c expression in gastric car-cinoma, consequently regulating the invasion and migration of carcinoma cells.

Clinical data of 23 elderly patients with rectal cancer undergoing trans-sphincteric local resection(TSLR, Mason's operation)were retrospectively analyzed. All the 23 patients were followed-up for three to seven years after operation, 18 with normal or good fecal continence(78%), five just in fair condition(22%)and none in fecal incontinence. Three-year survival was 83 percent(19/23)and 5-year survival was 78 percent(18/23)for them. It is suggested that TSLR is a safe, feasible and effective treatment for middle and low rectal cancer in the elderly with a long term survival and satisfactory quality of life.
