ObjectiveTo explore the psychological training methods on improving the mental adaptation and performance of recruits.MethodsAccording to army's squad establishment,372 recruits were randomly extracted and divided into intervention group (182) and control group (190).A series of special group psychological trainings,such as Warm barracks,Friendly Care,Self-awareness,Interpersonal communication,etc,was applied to the recruits of the intervention group through the squad leaders given psychological training.The effect was assessed with Psychosocial Stress Survey For Groups (PSSG),General Maladjustment Scale (GM),Social Support Rating Scale (SSRS),General Self-Efficacy Scale (GSES),Wallace Slef-Concept Scale (WSCS) and Examined Performance.ResultsThe scores of negative emotion was [(3.89±2.01) score vs (2.56±1.65) score ],negative copy was [(3.96±2.52) score vs (2.97±1.78)score],total stress was [(46.36±21.74)score vs (33.71±17.56) score],maladjustment was [(11.26±5.04)score vs (9.10±4.53)score] in the intervention group,which was significantly reduced than those in the control group(P＜0.01).But the scores of positive emotion was [(3.70±1.62) score vs (4.16±1.84) score],positive copy was [(5.21±1.94) score vs (6.93±2.17) score ],subjective support was [(21.37±3.59)score vs (22.56±3.53)score] and support utilization was [(7.03±2.16) score vs (8.92±2.44) score],self-concept was [(74.33±15.72) score vs (80.65±13.98) score],self-efficacy was [(2.44±0.56) score vs (2.91.±0.52) score ] and the examination performance was [(pull-up:(5.12±3.77) times vs (12.09±4.52) times; sit-up:(30.82±9.54) times/3 min vs (70.20±16.83) times/3min; push-up:(21.32±9.73)times/2 min vs (61.75±17.62)times/2 min; Running 3000 meters:(14.17±1.14) s vs (12.82±0.32) s; standing grade throw:(26.68±4.62) mvs (35.38±8.44) m ],which was significantly improved (P＜0.01 or P＜0.05).ConclusionsComprehensive group psychological training implemented by Squad leader could effectively improve the ability of adaptation of recruits and promote the performance.

Objective To investigate the anti - stress activity of thymopentin ethyl ester. Methods Anti - stress activity was evaluated by heat stress model and chronic uncontrolled stress model. Heat stress model;of 60 KM mice were divided into six groups. Except the controlled group, the other mice were maintained in 42℃ for 1h. Chronic uncontrolled stress model:of 60 KM mice were divided into six groups. Except the controlled group, the other mice were given three different stimulations once a day for continuous 21 d. The controlled group and model group were injected saline 0.2ml, and the three test groups were respectively injected thympentin ethyl ester at 2mg/kg,0.2mg/kg, 0.02mg/kg subcutaneously. The positive controlled mice were given thymopentin 0.2mg/kg subcutaneously. At the end of the experiment, plasma corticosteroid, IL -2 and SOD were determined according to the kit instructions. Results The activities of thymopentin ethyl ester in suppressed corticosteroid up - regulation and the elevated plasma IL - 2 and SOD level were more significant than those of thymopentin(P

Objective:To investigate the self-perceived aging status of the elderly in Changsha and analyze its influencing factors.Methods:From July to August in 2020, the convenient sampling method was used to select 402 elderly people in Changsha as the research object, the general data questionnaire, the elderly self-perceived aging questionnaire, the family care questionnaire and the positive psychological capital questionnaire were used to investigate them. Multiple linear regression analysis was used to analyze the influencing factors of self-perceived aging after logarithmic transformation.Results:The total score of self-perceived aging of the elderly was 109.00(102.00, 112.00), the total score of family care was 5.00(3.00, 8.00) and the total score of psychological capital was 80.00(66.00, 87.25). Regression analysis showed that the gender, educational level, age, the forms of health care, quarrels in family relationships, children visit frequency and the degree of family care were the important factors affecting the self-perceived aging of the elderly( P<0.05). Conclusions:The self-perceived aging level of the elderly is at a medium level, it is suggested that relevant departments take comprehensive measures to create positive self-aging environment.

Objective: To investigate the effects of definitive repair surgery on health-related quality of life (HRQOL) in patients with bile duct injury after laparoscopic cholecystectomy (LC). Methods: The retrospective case-control study was conducted. The clinicopathological data of 181 patients with bile duct injury caused by LC for benign gallbladder diseases who underwent definitive repair surgery and 50 patients without complications after LC for benign gallbladder diseases in the Mianyang Central Hospital from January 2000 to December 2017 were collected. There were 82 males and 99 females of 181 patients with bile duct injury, aged from 31 to 68 years, with an average age of 47 years. Definitive repair surgery was performed according to different types of bile duct injury, and questionnaire of HRQOL was conducted preoperatively and one year after operation. There were 18 males and 32 females of 50 patients without complications after LC, aged from 35 to 69 years, with an average age of 41 years. Questionnaire of HRQOL was conducted on LC patients without complications one year after operation. Observation indicators: (1) classification of bile duct injury; (2) intraoperative situations of definitive repair surgery; (3) postoperative situations of definitive repair surgery; (4) follow-up; (5) results of the SF-36 scale assessment. Follow-up was conducted by outpatient examination and telephone interview up to December 2018. Patients were reexamined liver function and color Doppler ultrasonography once every 6-12 months, and further magnetic resonance cholangiopancreatography (MRCP) or computed tomography examination to detect recurrence of anastomotic biliary stricture and cholangitis. Measurement data with normal distribution were expressed as Mean±SD, and comparison between groups was analyzed by the paired t test. Measurement data with skewed distribution were described as M (range), and count data were described as absolute numbers. Results: (1) Classification of bile duct injury: of the 181 patients with bile duct injury, there were 64 cases of E1 type, 70 cases of E2 type, 35 cases of E3 type, 9 cases of E4 type, and 3 cases of E5 type. (2) Intraoperative situations of definitive repair surgery: all the 181 patinets with bile duct injury underwent definitive repair surgery successfully, including 61 undergoing end-to-end biliary anastomosis, 109 undergoing Roux-en-Y choledojejunostomy, 11 undergoing hemi-hepatectomy combined with Roux-en-Y anastomosis. There were 52 patients combined with hilar cholangioplasty. The operation time and volume of intraoperative blood loss of 181 patients were (190±126) minutes and 601.5 mL (range, 150.0-2 100.0 mL). There were 24 cases with blood transfusion and 18 cases with T-tube stent. (3) Postoperative situations of definitive repair surgery: 40 of 181 patients had complications, including 14 cases of incisional infection, 10 cases of bile leakage, 8 cases of perihepatic effusion, 7 cases of pulmonary infection, and 1 case of abdominal hemorrhage. The patient with postoperative abdominal hemorrhage underwent reoperation for hemostasis, and other patients with complications were cured after ultrasound-guided puncture and drainage or conservative treatment. Duration of postoperative hospital stay of 181 patients with bile duct injury was 12.6 days (range, 6.0-34.0 days). There was no perioperative death occurred. (4) Follow-up: 157 of 181 patients were followed up for 8.2-201.3 months, with a median follow-up time of 92.7 months. Twenty-eight patients had anastomotic stricture recurred, 16 of which were treated with reoperation, 10 were treated with endoscopic stent implantation, and 2 cases were treated with balloon dilatation in interventional department; the stricture was repaired again in all cases. Thirteen patients had recurrent cholangitis, showing no obvious anastomotic stricture on MRCP, and symptoms can be effectively controlled after conservative treatment. (5) Results of the SF-36 scale assessment: 181 patients with bile duct injury completed the SF-36 scales before definitive repair surgery, and 157 completed one year after definitive repair surgery. All the 50 patients without complications completed SF-36 scales one year after LC. The scores of HRQOL in physiological function, role functioning, somatic pain, general health, vitality, social function, emotional function, mental health, the scores of physical component summary, and mental component summary of 181 patients with bile duct injury before surgery were 79±15, 65±12, 40±17, 42±14, 59±20, 27±15, 48±23, 56±22, 60±11, and 56±11, respectively. The above indices one year after definitive repair surgery were 87±10, 78±15, 71±20, 64±20、68±19, 70±25, 67±21, 69±23, 71±13, 68±15, respectively. The above indices of 50 patients without complications one year after LC were 90±13, 81±20, 87±16, 72±20, 73±15, 86±17, 79±22, 77±19, 82±18, 79±18, respectively. The 181 patients with bile duct injury had significant elevation in above indices one year after definitive repair surgery (t=2.051, 2.016, 3.875, 3.014, 2.563, 3.225, 2.964, 2.357, 2.150, 2.203, P<0.05). The 50 patients without complications also had significant elevation in above indices one year after definitive repair surgery (t=2.817, 2.206, 3.641, 3.112, 3.202, 3.310, 3.011, 2.899, 2.150, 2.118, P<0.05). There were significant differences in the general health and mental health one year after definitive repair surgery between 181 patients with bile duct injury and 50 patients without complications (t=2.014, 2.011, P<0.05), and no significant difference in the physiological function, role functioning, somatic pain, vitality, social function, or emotional function between the two groups (t=0.852, 0.915, 0.907, 1.102, 1.284, 1.120, 0.863, 1.109, P>0.05). Conclusion Definitive repair surgery can significantly improve HRQOL in patients with bile duct injury caused by LC.

Objective: To study hemihepatectomy combined with a circular-stretching suturing technique in bile duct anastomosis in treatment of high level bile duct injuries (BDI). Methods: From January 2000 to January 2018, eleven patients with high level BDI caused by laparoscopic cholecystectomy (LC) were treated in Mianyang Central Hospital with hemihepatectomy combined with a circular-stretching suturing technique in the bile duct anastomosis. The hilar confluence was involved in all these patients. A total of six patients had combined right hepatic artery injury with 1 having associated right portal vein injury. A total of five patients had developed right liver atrophy. The median time interval from LC to hepatectomy was 17.0(2.0~61.0) months. The number of previously attempted biliary repairs was 1~4 times (median 2 times). The bile duct anastomosis was performed by the circular-stretching suturing technique. Results: There was no perioperative death. One patient underwent left hemihepatectomy and 10 patients right hemihepatectomy. Roux-en-Y hepaticojejunostomy was carried out in 9 patients, and bile duct end-to-end anastomosis in 2 patients. The operation time was (245.9±87.4) min, intraoperative blood loss (655.7±413.6) ml, and the median postoperative hospital stay 12.0(7.0~29.0) days. Five patients developed complications. The median follow-up was 47.0(15.0~89.0) months. One patient developed anastomotic stenosis and 1 patient had cholangitis. The remaining 9 patients were well. Conclusion After adequate preoperative preparation, patients who were treated with hemihepatectomy combined with the circular-stretching suturing technique for bile duct anastomosis to treat high level BDI achieved good results.
