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.

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.

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.

Background and purpose: Germline variation in Tg (thyroglobulin) and TSHR (thyroid stimulating hormone receptor) confers an increased risk of benign thyroid disorders. Benign thyroid disorders are strong risk factors for non-medullary thyroid cancer (NMTC). To explore the hypothesis that polymorphic variation in these genes affects the risk of NMTC. Methods: Tg A7589G and TSHR C253A polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (FCR-RFLP) method, to analyze the relationship between the Tg and TSHR gene polymorphisms and NMTC in NMTC and control groups. Results: Among 360 cases, there was no statistic difference in the frequencies of genotype and allele of TSHR C253A between NMTC and control groups. There were Tg A7589G polymorphisms in the 360 cases. The frequencies ofAG+GG genotype in NMTC group were significantly higher than those in control groups (P<0.05). The frequencies of G allele in NMTC group were significantly higher than those in control groups (P<0.001). Conclusion: There were Tg A7589G gene polymorphisms in NMTC and control groups. G allele may be the predisposing gene of NMTC.

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 curative effect on non-obese type 2 diabetes and the effect on change of glucagon-like peptide-1 (GLP-1) of gastric bypass operation. Methods Thirty-two cases of gastric ulcer with non-obese type 2 diabetes were suffered gastric bypass operation. Plasma glucose concentrations, insulin and GLP-1 were measured respectively in fasting and postprandial conditions before operation and in week 1, 2, 3 and month 1, 3, 6 after gastric bypass operation, and the body mass index (BMI), homeostasis model assessment ? cell function index (HBCI) and glycosylated hemoglobin (HbA1c, the index was detected only before operation and in month 3, 6 after operation) were also measured. The turnover of the diabetes condition in the 6th month after surgery was observed. Results Compared with the levels before operation, the fasting and postprandial plasma glucose levels were descending (P0.05). The diabetes control rate was 78.1%(25/32) overall six months after operation. Level of GLP-1 was negatively correlated with level of plasma glucose (P
