Objective To explore the relationship between Commitment to Supervisor and Job Satisfaction and investigate the mediating role of psy?chological capital,so as to provide theoretical basis for improving their job satisfaction and promoting physical and mental health. Methods The stratified random sampling method was used to investigate 2 800 police from 7 cities in Liaoning province during the period of August to November 2014(Four questionnaires were carried out under investigation,including questionnaire of personal information,questionnaire of commitment to su?pervisor, questionnaire of psychological capital and questionnaire of job satisfaction),and the effective respondents was 2 193(78.3%). Re?sults Commitment to supervisor was positive associated with job satisfaction(β=0.488,P<0.01),and psychological capital was positive associat?ed with job satisfaction(β=0.552,P<0.01). Commitment to supervisor explained 23.7%of variance in job satisfaction while psychological capital explained 13.6%of variance in job satisfaction. Conclusion Commitment to supervisor and psychological capital have effective predictive value on police’job satisfaction. In addition,the results of study forecast that psychological capital has a mediating effect between commitment tosSupervisor and job satisfaction.

0.05);one week after surgery,the fasting blood glucose level showed a sustained and steady downward trend(P0.05).Conclusions Gastric bypass operation has a good therapeutic effect on type 2 diabetes in the non-obese patients,and this therapeutic effect is not dependent on loss of body weight.

Anus fine of low rectal cancer surgery, can make the quality of Life of patients significantly im-proved,but postoperative anastomotic leakage is still the main complication, its occurrence can lead to in-creased perioperative mortality, prolonged hospitalization, increased cost, causing a great deal to patients suffering. In this paper, we review the causes and prevention of low rectal cancer after anterior resection of anastomotic leakage.

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

Objective To study the anatomy of the caudate lobe and to apply the knowledge in caudate lobe resection and piggyback liver transplantation. Methods Dissection of the caudate lobe was carried out in 35 fresh adult livers. Before dissection, the portal venous system was injected with barium sulfate emulsion to show the portal branches of the caudate lobe. Results The caudate lobe was shown to consiste of 3 portions: (1) the Spigelian lobe, the paracaval portion and the caudate process. The Spigelian lobe was pyramidal in shape with 3 faces, a peak and a base; (2) the paracaval portion was situated to the right and to the front of the vena cava; (3) the caudal process was the liver parenchyma between the hepatic hilum and the anterior aspect of the vena cava. Conclusions The entire caudate lobe is situated at the posterior part of the liver and it surrounds the vena cava. The key point in resecting the entire caudate lobe or in performing a piggyback liver transplantation is adequate mobilization and division of all the outflowing veins of the caudate lobe.

Objective To investigate the effect of small intestine exclusion surgery on blood glucose and oral glucose tolerance test (OGTT) in Goto-Kakizaki (GK) rat with type Ⅱ diabetes mellitus.Methods 40 GK rats were randomly divided into 5 groups:duodenal bypass (Group A,n = 8),duodenaljejunal bypass (Group B,n = 8),duodenum and total jejunum exclusion (Group C,n = 8),sub-total small intestine exclusion (Group D,n = 8),and sham-operation (Group SO,n=8).All rats were observed for 24 weeks after surgery.Fasting blood glucose was tested at 0,1,3,6,12,and 24 wk.OGTT was performed at 0,1,and 24 wk.After the administration of 3 g/kg glucose by oral gavage,blood glucose was measured in conscious rats before (baseline) and after 30,60,120,and 180 minutes.Areas under curves (AUC) were calculated by trapezoidal integration.Results Rats in group A,B,C and D had lower fasting blood glucose levels and better oral glucose tolerance as shown by lower peak and area-under-thecurve (AUC) glucose values through the entire follow-up period[group B (fasting blood glucose:(9.0±2.4) mmol/L vs.(4.4±1.0) mmol/L;OGTT peak:(20.8±3.1) mmol/L vs.(10.3±2.0) mmol/L;AUC:(2658±417) mmol·min/L vs.(1324±317) mmo·min/L,P ＜0.05 or P ＜0.01].Fasting blood glucose had no differences before 12 wk and significantly increased at 12 (9.1±2.4) mmol/L and 24 wk (10.0±2.3) mmol/L in group SO (preoperative values were (8.1±1.9) mmol/L,P ＜ 0.01.There was no differences in oral glucose tolerance as shown by lower peak and area-under-the-curve (AUC) glucose values between 0 and 1 wk (P＞0.05),while the oral glucose tolerance become worse as shown by the delay of peak,higher peak (25.6±2.0) mmoL/L vs.(21.4±2.7) mmoL/l,and AUC (3422±360) mmol·min/L vs.(2667±377) mmol·min/L.Glucose values in group SO at 24 wk compared to preoperatively (P＜0.01).Rats in group A,B,C,and D had lower fasting blood-glucose and better oral glucose tolerance compared with sham-operated group through the entire follow-up period (P＜0.05 or P＜0.01).Rats in group B had lower fasting blood-glucose and better oral glucose tolerance compared to those in group A while the effect on diabetes control in group B,C and D were similar to one another (P＞0.05).Conclusion Small intestinal exclusion containing proximal gut was effective for glucose control and improving gucose tolerance,duodeno-jejunal bypass may be applicable for diabetes control in clinical setting.

Objective: To observe the effects of early enteral nutrition(EEN) on incidence of postoperative complication in gastric cancer patients. Methods: 150 patients with gastric cancer were randomly divided into early enteral nutrition group (n=82) and non-early enteral nutrition (N-EEN) group (n=68). The patients in group EEN were given enteral nutrition after operation, and the patients in group N-EEN were given total parenteral nutrition support. The postoperative complications were recorded. The serum albumin, prealbumin and transferrin were measured on postoperative day 1, 5 and 9. The serum level of alanine aminotransferase(ALT), bilirubin, blood urea nitrogen(BUN), creatinine, glucose, cholesteroland triglyceridewere monitored. Results: The complications occurred in 21patients. 5 of these patients belonged to EEN group and the other belonged to N-EEN group. In EEN group, the serum albumin, prealbumin and transferrin were significantly higher than in N-EEN group on postoperative day 9 (P

Objective:To elucidate the role of ERK1/2 MAPKs signal transduction in the protective effects of ischemic preconditioning during liver transplantation. Methods: Twenty-four rats were equally randomized into 4 groups: sham control (group A); liver transplantation (group B); ischemic preconditioning+liver transplantation (group C), and MEK inhibitor intervention+ischemic preconditioning+liver transplantation (group D). Serum AST and ALT were detected after operation and cellular ultrastructures were observed by transmission electron microscopy. Liver tissue ERK1/2 MAPKs phosphorylation activities were evaluated through determining ERK-1 protein phosphorylation by Western blotting. Results: Serum ALT and AST activity in group B and group D was significantly higher than those in group A, and remained normal in group C. Liver tissue ERK1/2 MAPKs phosphorylation activity increased significantly in group C, and the activation effect was inhibited in group B and D. Cellular ultrastructure was obviously damaged in group B and group D, and the damage was prevented in group C.Conclusion: Ischemic preconditioning has a protective effect on transplanted liver cells in which ERK1/2 MAPKs pathway plays a pivotal role.
