Objective: To investigate the clinical effects of early enteral nutrition in severe brain injury patients requiring mechanical ventilation. Methods: 56 patients requiring mechanical ventilation were randomly divided into two groups:A(n=28),EEN group peptisorb,1 000 ml a day;B(n=28),control group,PN.The changes of serum total protein,blood albumin,immune globulin,lymphocyte count,nitrogen balance,oxgenation index(PaO2/FiO2),ventilation parameter and blood routine were measured.APACHE Ⅱ,incidence of ventilator-associated pneumoniasurvival rate for 28 days and days in hospital were observed.Results: Incidence of ventilator-associated pneumonia,28 d-survival rate and mean hospitalization day were significantly different(P

Objective To investigate the diagnostic value of serum liver function indexes for gallbladder stones combined with asymptomatic secondary common bile duct stones.Methods The retrospective cohort study was conducted.The clinical data of 460 patients with gallbladder stones who were admitted to the Affiliated Hospital of Zunyi Medical College from June 2012 to June 2016 were collected.Of 460 patients,106 combined with asymptomatic secondary common bile duct stones and 354 with gallbladder stones were allocated into the common bile duct stone group and gallbladder stone group,respectively.The serum liver function test was applied to the 2 groups,including alanine transaminase (ALT),aspartate transaminase (AST),total bilirubin (TBil),direct bilirubin (DBil),glutamyltransferase (GGT) and alkaline phosphatase (ALP).The receiver operating characteristic (ROC) curve was built using significant statistical indicators,and correspondent cut-off value,sensitivity and specificity were calculated according to ROC curve.Observation indicators:(1) comparison of serum liver function indicators (ALT,AST,TBil,DBil,GGT,ALP) between the 2 groups;(2) analysis result of ROC curve.Measurement data with normal distribution was represented as x±s.The comparison between groups was evaluated with the independent-sample t test.The comparison of count data were analyzed using the chi-square test.The ROC curve analysis was done for significant statistical indicators.Results (1) Comparison of serum liver function indicators between the 2 groups,the levels of ALT,AST,TBil and DBil were (32±8)U/L,(35±8)U/L,(12.8±2.5)μmol/L,(2.6±0.4)μmol/L in the common bile duct stone group and (30±7)U/L,(32±7)U/L,(12.2± 2.4)μmol/L,(2.5 ±0.4)μmol/L in the gallbladder stone group,respectively,with no statistically significant difference (t=0.891,0.786,0.924,1.026,P＞0.05).The levels of GGT and ALP were (162±43) U/L and (145±37) U/L in the common bile duct stone group and (36± 10)U/L and (128±23) U/L in the gallbladder stone group,respectively,with significantly statistical differences (t =20.859,2.483,P＜0.05).(2) Result of ROC curve showed that areas under the curve of GGT and ALP were respectively 0.963 [95％ confidence interval (CI):0.938-0.988] and 0.621 (95％CI:0.561-0.684).The correspondent cut-off value of diagnostic accuracy,sensitivity and specificity of GGT and ALP were 92.5 U/L and 139.5 U/L,91.6％ and 50.7％,95.7％ and 76.5％,respectively.Conclusion The abnormally elevated levels of serum GGT have major diagnostic value for patients with gallbladder stones combined with asymptomatic secondary common bile duct stones,with an advantage of convenient and fast operation,and it is worth to be applied and popularized.

Objective To explore the differences of occupation burnout of the soldiers in southern and northern Xinjiang and explore its related influencing factors.Methods Using stratified randomization sampling method,500 soldiers from south and north of xinjiang military were selected and investigated by Military Job Burnout Scale and Military Social Support Rating Scale.Results ① The military of northern soldiers'accomplishment,somatization,interpersonal relationship,social support score (5.57±3.29,5.53± 3.35,3.38±2.75,9.62± 10.15) was significantly higher than the soldiers who live in south of xinjiang (5.26±3.25,5.13±3.45,2.94±2.39,6.25±5.24) (t=2.091,-2.539,-4.011,7.227,P＜0.05).②Every dimensions of occupation bumout has significant correlation with social support,age,length of military service,marriage,level,working hours,income and job satisfaction (r=0.124,0.220,0.275,0.198,0.192,0.206,0.188,-0.383,P＜0.05).The total score of Military Job Bumout Scale has positive correlation with social support and level (r=0.122、0.410,P＜0.01).③Social support,working hours,job satisfaction and length of military service has forecast effect on the northern military occupation bumout.Social support and level can predict the southern military occupation burnout.Conclusion It is no obviously differences on the general occupational between the north and South Xinjiang Military.Social support is closely related to the job burnout of South and the North military.

Objective To investigate the relationship among A-type behavior,job burnout and psychosomatic health in grassroots officers and soldiers stationed in Xinjiang, which provides the theoretical basis to maintain their psychosomatic health.Methods Evaluation was carried out with A-type behavior questionnaire, military job burnout scale and simple soldiers psychosomatic health scale in 1 939 grassroots officers and soldiers chosen by random cluster sampling method from army stationed in Xinjiang.Results ①The total scores and each factor scores of the scale had significant positive correlation among the physical scale, the job buruout scale and time hurry (TH) ,competitive and hostility (CH) (r=0.170-0.716, P＜0.01).②Job burnout entered into the physical and mental health regression equation and could explain 68.6％ of the variance(β=0.195, t=32.211, P＜0.01);TH, CH entered the regression equation of job burnout and could explain 29.5％ of the variance(t=4.925,4.427).③ TH indirectly affected physical and mental health through job burnout, the mediating effect of the amount was 0.27 ×0.83=0.2241;CH indirectly affected physical and mental health by job bumout,the mediating effect of the amount was 0.30×0.83 =0.2490.Conclusion Job burnout has fully mediated effect between TH, CH and physical and mental health.

Objective To study characters of pathology associated with functional alteration of primary brainstem injury (PBI) at different injury severities in rabbits .Methods Animal model of graded PBI was produced using rabbits .Animals were di‐vided into five groups ,group Ⅰ to Ⅳ with an increase of impact power ,10 cases in each group ,and the control group with 5 cases . The pathology characters of PBI were investigated combining dissection observation with unaided eye ,tissue HE histochemical stai‐ning and electron microscope .Results Slight brainstem injury were observed in group Ⅰ ,and pathological results showed regional subarachnoid hemorrhage (SAH) ,stripping of regional cerebral pia mater ,a few petechial hemorrhage in surface ,nerve cell edema , normal medulla sheath and axon roughly .The brainstem injuries were apparent in group Ⅱ ,and the pathological changes indicated SAH in sheet ,petechial and sheeted hemorrhage in surface ,and slight swelling and vacuoles in nerve cells .The brainstem injuries were observed obviously in group Ⅲ ,exhibiting thick SAH ,petechial and sheeted hemorrhage in surface and inside ,degeneration of nerve cells ,abruption of axon ,and atrophy of axoplasm .Eight of ten animals died of respiratory depression induced by brainstem in‐jury in group Ⅳ ,presenting thick hemorrhage in subarachnoid surrounding brainstem ,the whole brainstem injured ,microscopically with multiple small hemorrhage ,nerve cells only residual nuclei ,myelin lamellar severe stratification and fracture ,and axonal tran‐section ,disintegration .No abnormal pathological changes were shown in control group .Conclusion The impacts to brainstem with higher powers lead to more manifest functional and more severe pathological changes ,with an alternation of injury location from surface to deep .

Colorectal cancer is one of the most commonly seen gastrointestinal carcinomas and its pathogenesis has not yet been fully clarified. It is considered as a multi-step and multi-stage disease. Wnt signaling transduction pathway regulates cell growth,motility and differentiation,and plays a crucial role in the regulation of embryonic development and tumor genesis. This article reviewed the advances in study on Wnt signaling transduction pathway and colorectal cancer.
