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 develop recruits training burnout self-reported questionnaires, and test the reliability and validity.Methods 780 recruits(360 for first test ,420 for second test) in Xinjiang were randomly assesscd with training burnout self-reported questionnaires.Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were applied to the data, and tested the reliability and validity of recruits training burnout self-reported questionnaires.Results The questionnaires consisted of 13 items and 3 dimensions.One of the dimensions (physically and psychologically exhausted situation, training-alienation, low accomplishment) , explained 61.599％ of the total variance.Cronbach's α coefficient of the whole questionnaire was 0.837, Cronbach's α coefficient of each partial scale were between 0.775 and 0.807.Split-half reliability of the whole scale reached to 0.817, split-half reliability of each partial were between 0.758 and 0.793.The correlation coefficient among each dimensions were 0.267 to 0.569 (P＜0.01) ,and the coefficient between each dimensions and the total score were between 0.671 and 0.857(P＜0.01).Confirmatory factor analysis showed that three factor model was optimal (GFI =0.935, AGFI =0.902, NFI =0.907, CFI =0.936, IFI =0.935, RMSEA =0.050).The three dimensions and the total questionnaire had significant positive correlations with mental stress (r=-0.215--0.313, P＜ 0.01) and significant negative correlations with depression(r=0.319-0.602, P＜0.01).Conclusion The recruits training burnout self-reported questionnaires meets the requirements of psychological surveying, and could be used to text recruits training burnout.

Objective To compare the efficacy of the laryngeal mask airway Classic (CLMA), Streamlined Liner of Pharyngeal Airway (SLIPA) and laryngeal mask airway ProSeal (PLMA) in patients undergoing laparoscopic surgery. Methods One hundred and twenty-three ASA Ⅰ or Ⅱ patients aged 20-64 yr undergoing elective laparoscopic surgery were randomly divided into 3 groups: CLMA group (group C, n =41 ), SLIPA group (group S, n =42) and PLMA group (group P, n =40). Laryngeal mask was inserted after induction of anesthesia with sufentanil 0.3 μg/kg, atracurium 0.5 mg/kg and propofol 2 mg/kg. Mll the patients were ventilated with intermittent positive-pressure ventilation. Anesthesia was maintained with contiunous infusion of propofol 6-8 mg· kg-1· h-1 and with supplementary administration of sufentsnil 0.1-0.2 μg/kg and atracurium 0.2 mg/kg as required. The degree of difficulty in inserting the laryngeal mask was evaluated. The rate of successful placement at first attempt, device placement time, recovery time and complications were recorded . Peak inspiratory pressure (PIP) and the number of patients with an airway sealing pressure less than PIP were recorded before pneumoperitoneum and when intra-abdominal pressure achieved 12 mm Hg. Results The placement was easier and the placement time and recovery time were significantly shorter in group S, and the placement time was significantly longer,the airway sealing pressure was significantly higher and the number of patients with an airway sealing pressure less than PIP was lower in group P than in group C ( P ＜ 0.05). The placement time and recovery time were significantly longer, the placement was harder, the airway sealing pressure was significantly higher, and the number of patients with an airway sealing pressure less than PIP was lower in group P than in group S ( P ＜ 0.05). PIP was significantiy higher when intra-abdominal pressure achieved 12 mm Hg than that before pneumoperitoneum in all the three groups ( P ＜ 0.05). There was no significant difference in the incidence of complications and rate of successful placement at first attempt among the three groups ( P ＞ 0.05). Conclusion All the three airway devices can provide adequate ventilation during operation, with fewer complications. SLIPA placement is easiest. PLMA can assure good airway sealing and is most suitable for patients undergoing laparoscopic surgery.

Objective To investigate the intermediary and regulating effect of self?esteem on per?ceived stress and training burnout among accelerated plateau soldiers. Methods A total of 700 accelerated plateau soldiers were investigated which were chosen by a random cluster sampling method,and assessed by the Perceived Stress Scale, Self?esteem Scale and Self?compiled Soldiers' Training Burnout Questionnaire. Results ( 1) The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a history of training injury (27.85±5.80,14.89±3.46 and 6.89± 2.26,respectively) were significantly higher than those of soldiers who didn't have a history of training injury (25.05±5.12,12.68±3.25 and 6.16±2.78,respectively),and the differences were significant ( t= 4.321, 5.764,2.825,all P<0.01). The total score of training burnout,the score of physical and mental exhaustion and the score of training alienated among soldiers who had a high training expectation were higher than those of soldiers who didn't have a high training expectation,and the differences were significant (P<0.01). (2) Among accelerated plateau soldiers,training burnout showed significantly positive correlation with perceived stress ( r=0.323, P<0.01),and significantly negative correlation with self?esteem ( r=-0.409, P<0.01). (3) The intermediary role of self?esteem between perceived stress and training burnout was remarkable (P<0.01) ,which accounted for 33.8% of the total effect,and self?esteem also had a regulating effect (P<0.05) . Conclusion Radical plateau soldiers have remarkable differences due to the history of training injury or training expectations,and self?esteem has partial intermediary and regulating effect between perceived stress and training burnout.

OBJECTIVETo observe the pathological and clinical characters of nonalcoholic steatohepatitis (NASH).

METHODSLiver biopsy tissues taken from 97 patients negative for common viral detection with serological test and immunohistochemistry as well as in situ hybridization, were observed by routine light microscopic examination. And the clinical data of patients with NASH was analyzed.

RESULTSAmong the chronic hepatitis patients with unknown etiology, the detection rate of NASH was 15.5% (15/97). The characteristic lesions in NASH patients included macrovesicular steatosis in zone 3 of lobules, hepatocytes ballooning degeneration, lobules diffused with acute and chronic inflammation, and perisinusoidal fibrosis. Grading and staging according to Brunt's method, histological lesions could be accounted for G1S1 in 7 patients, G2S2 in 3 patients, G3S1 in 4 patients and G3S2 in 1 patient. There were 14 patients with mild to moderate elevation of transaminase, 10 with hyperlipemia, 8 with diabetes and 9 with fatty liver by ultrasonography.

CONCLUSIONNonalcoholic steatohepatitis is a common form of unknown etiology chronic liver disease with certain clinic-pathological features.

OBJECTIVE: To investigate the relationship among perceived stress,sleep and fatigue status; and to analyze the effect of sleep status in mediating and regulating perceived stress and fatigue status in soldiers that were acutely exposed to high altitude for the first time. METHODS: A total of 700 soldiers that were acutely exposed to high altitude for the first time were investigated with convenient sampling. They were evaluated using Perceived Stress Scale,Sleep Status Self-evaluation Test,and Fatigue Scale-14. The mediating effect was analyzed by structural equation model,and the moderating effect was analyzed by hierarchical regression analysis. RESULTS: The total score of fatigue among soldiers that often took part in recreational activities was significant lower than that who did not( P < 0. 01). The total score of fatigue among soldiers that had training injury was significant higher than that who had not( P < 0. 01). The total score of fatigue among soldiers that had high training expectations was significant higher than that that didn't have high training expectations( P < 0. 01). Sleep status,sense of overload and training expectations had remarkable predicting effect on fatigue status among soldiers that were acutely exposed to high altitude for the first time( P < 0. 01). Sleeping status has a complete mediating effect on the sense of prediction,sense of overload and fatigue status( P < 0. 01),and has a moderating effect on the sense of control,sense of overload and fatigue status( P < 0. 01). CONCLUSION:s Perceived stress and sleeping status had close relationship with fatigue status among soldiers that were acute exposed to high altitude for the first time. Sleeping status has intermediary and regulating effect between senses of overload and fatigue state.

Objective To study the characteristics and trends of drug price fluctuation in our country in order to provide reference for the governments in evaluating their policy for the macro-control and management of drug price. Methods The drug price fluctuation was empirically analyzed using the ARCH model according to the monthly drug price data from 2011 to 2017. Results The drug price presented a fluctuant increasing trend with an even fluctuation amplitude and frequency, especially after its reform in 2015. The fluctuation of drug price did not show any clustered feature and significant impact on information but a rather strong memory. Conclusion The fluctuation of drug price is relatively stable in our country. The drug price control policy plays a rather effectively role in stabilizing thefluctuation of drug price. It is thus suggested that the governments should bring their role into full play in controlling drug price, regulating drug marketing, and supervising drug price.

Objective: To evaluate the safety, efficacy and feasibility of transoral robotic surgery (TORS) for parapharyngeal space (PPS) neoplasms. Methods: We collected data from 7 patients with PPS neoplasm who received TORS in Sun Yat-sen University Cancer Center between May 2017 and November 2020, and patients' clinical and pathological characteristics were analysed. There were 2 men and 5 women with age ranged from 35 to 76 years. Among them, 2 patients underwent secondary surgery, 2 patients required combined transcervical approach to complete surgery, and 1 patient was suspected of ipsilateral cervical lymph node metastasis and scheduled for diagnostic TORS. The preoperative tumor size, operation time, intraoperative blood loss, postoperative bleeding, dyspnea, neurological impairment, feeding time and postoperative hospital stay were analyzed. SPSS 24.0 was used to analyze the data. Results: TORS was performed successfully with complete removal of tumors in all 7 cases. Among 6 patients with curative TORS, 5 patients received TORS with postoperative diagnoses of neurogenic tumors and 1 patient underwent TORS combined transcervical approach with postoperative disgnosis of recurrent pleomorphic adenoma; no intraoperative tumor rupture occurred; the intraoperative blood loss was 20-200 ml with a median of 40 ml; the operation time was 65.0-238.0 min with a median of 77.5 min; the oral feeding time was 3-6 days with a median of 3 days; and the postoperative hospital stay was 4.2±1.6 days. One patient presented with neck swelling 3 days after surgery, but this symptom relieved 3 days later after treatments with antibiotic, hemostasis and detumescence. One patient received diagnostic TORS, as intraoperative pathology indicating a recurrent pleomorphic adenoma, then the neoplasm got completely resected through transcervical-transparotid approach. None of 7 patients manifested with airway obstruction, bleeding or nerve injury symptoms after operation. All patients were followed for 2 to 44 months, no local recurrence or distant metastasis was found. Conclusions: TORS is a safe, effective and feasible treatment for selected PPS neoplasms, with less cosmetic impact, less trauma and blood loss, few postoperative complications, enhanced postoperative recovery and short hospital stay.
