Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ～ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ～0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ～0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ～ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ～ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ～ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.

Objective To explore correlation between alexithymia and resilience in military personnel.Methods 2802 subjects were chosen by random cluster sampling to outline the military personnel resilience scale and military alexithymia scale.The data were analyzed by t-test,chi-square test,ANOVA,correlation analysis and multiple linear regressions analysis.Results The prevalence rate of alexithymia was 6.85％,while resilience was 6.60％.Compared to sea force (45.62 ± 11.25 ) and air force (45.32 ± 9.98 ) subjects,land force (47.92 ± 9.92)had significantly higher total score in alexithymia(P＜ 0.05 ).Compared to sea force (87.35 ± 12.15 ) and air force ( 88.58 ± 10.39 ) subjects,land force ( 85.73 ± 10.70) had significantly lower total score in resilience(P ＜ 0.05 ).The total score and every factor score of subjects with alexithymia were significant lower than those of control group in resilience(P ＜ 0.05 ).Every factor of Resilience Scale were mild negative correlation with every factor of Alexithymia Scale (P＜0.01).Problem solving,volition,optimism and family supports were the main factors which had affected on the alexithymia.Conclusion The prevalence rate of alexithymia in military personnel is lower than ordinary people,but there are still issues in alexithymia and resilience,particularly in land force.The research show mild correlation between alexithymia and resilience in military personnel.

Objective:To assess the implementation of injection-related risk management based on WeChat platform for type 2 diabetic patients with the insulin self-injection.Methods:A total of 124 diabetic patients, who would receive insulin therapy by self-injection at home after discharge from the PLA 903 hospital during April 2017 to July 2018, were divided into the control group( n=62)and the study group( n=62). All patients were given routine education on insulin injection during the hospitalization,while the study group( n=62)received additional video and text education based on WeChat platform after discharge. The skill of self-injection and the status of blood glucose control were evaluated in both groups 4 weeks and 8 weeks after discharge, respectively. Results:The insulin injection skill, including skin disinfection [36(58%) vs. 11(18%),χ 2=21.42, P<0.01], exhaust before injection [62(100%) vs. 51(82%),χ 2=12.07, P<0.01], stay 10s after injection [60 (97%) vs. 47(76%),χ 2=11.52, P<0.01], disposal of used needle[49(79%) vs. 18(29%),χ 2=31.20, P<0.01], rotation of injection site [48(77%) vs. 35(56%),χ 2=6.16, P=0.01], insulin storage [62(100%) vs. 57(92%),χ 2=5.21, P=0.02], and the ability of correctly dealing with hypoglycemia [52(84%) vs. 38(61%),χ 2=7.94, P=0.01] in the study group were significantly better than those in the control group after 4 weeks of injection-related risk management. The fasting plasma glucose [(6.41±0.76) vs.(7.19±0.81)mmol/L, t=5.61, P<0.01], glycosylated hemoglobin A1c [(6.71±0.64)% vs. (7.37±0.78)%, t=5.18, P<0.01], incidence of hypoglycemia [6(10%) vs. 15(24%),χ 2=4.64, P=0.03] in the study group were significantly lower than those in the control group after 12 weeks of the management. Conclusion:The risk management based on WeChat platform can improve insulin self-injection skill and the ability of dealing with hypoglycemia,also promote effective blood glucose control for diabetes patients.

Objective To explore the correlation between mental health and social support of the seven countries peacekeeping soldiers,and provide theoretical guidance for the peacekeeping soldiers to improve the mental health status.Methods Through random cluster sampling,1143 peacekeeping soldiers were investigated with Chinese Military Mental Health Scale (CMMHS) and Social Support Scale (SSS).Results The total score of CMMHS and depression factor((61.06 ± 3.99),(10.11 ± 1.67)) of the suicidal ideation peacekeeping soldiers were significantly higher than the no-suicidal ideation peacekeeping soldiers ((59.97 ± 3.73),(8.97 ± 1.81))(P ＜ 0.05),CMMHS total score and each factors of the seven countries peacekeeping soldiers were significantly higher than the Chinese soldiers norms (P ＜ 0.05),and the total scores ((28.50 ± 1.69)) of the social support of the suicide idea peacekeeping soldiers was lower than the no-suicidal ideation peacekeeping soldiers ((28.92 ±1.78)) (P＜0.05).The obsessive-compulsive factor,anxiety factor,depression factor,phobic anxiety factor,somatization factor,neurastheria factor and interpersonal sensitivity factor of CMMHS were the risk factors arise the mental diseases of the peacekeeping soldiers,especially the depression factor(OR =27.00,x2 =439.46,P ＜ 0.05).The CMMHS total score and each factors had obvious negative correlation with social support scores(r =-0.199 ～0.434,P ＜ 0.05).Analysis of multiple stepwise back displayed that the age,gender,education and social support were main factors of influencing mental health of the seven-country peacekeeping soldiers (age:t =2.428,educational level:t =-3.310,social support:t =1.990,P =0.047 ～ 0.01).Conclusion The suicidal ideation has close relationship with peacekeeping soldiers' psychological disease,and the mental health of the peacekeeping soldiers is influenced by the age,gender,education level,and especially by social support.

Objective To investigate the effects of sevoflurane postconditioning on myocardial ischemiareperfusion(I/R)injury in patients undergoing coronary artery bypass grafting(CABG)with cardiopulmonary bypass(CPB).Methods Forty NYHA Ⅰ -Ⅲ patients of both sexes,aged 55-64 yr,with BMI ＜ 30 kg/m2,scheduled for CABG under CPB,were randomly divided into 2 groups(n = 20): control group(group C)and sevoflurane postconditioning group(group S).Anesthesia was induced with midazolam and/or etomidate,fentanyl and rocuronium.Patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propefol and intermittent iv injection of fentanyl and pipecuronium.In group S,2% sevoflurane was inhaled continuously for 15 min immediately after aortic unclamping.After anesthesia induction,before CPB,10 min after the end of CPB,at the end of operation,and 6 and 24 h after operation,MAP,HR,CVP,mean pulmonary arterial pressure,pulmonary arterial wedge pressure,CO and S(v)O2 were recorded,and CI,SVI,systemic vascular resistance index and pulmonary vascular resistance index were calculated.Blood samples were taken from central vein before aortic clamping,at 6 h of reperfusion and 24 h after operation for determination of plasma creatine kinase(CK),creatine kinase isoenzyme(CK- M B)and lactate dehydrogenase(LDH)activities and tropenin I(TnI)concentrations.Myocardial tissues were obtained from right auricle before aortic clamping and at the end of CPB for observation of the ultrastructure and the severity of myocardial injury was assessed.Results There was no significant difference in hemodynamics and parameters of cardiac function between the two groups(P ＞ 0.05).Compared with group C,plasma CK-MB and LDH activities at 6 h of reperfusion and plasma CK activity and TnI concentrations at 24 h after operation were significantly decreased and the myocardial injury was significantly reduced after the end of CPB in group S(P ＜ 0.05).Conclusion Sevoflurane postconditioning can protect myocardium against I/R injury induced by CPB in patients undergoing CABG.

Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.

BACKGROUND: It has been confirmed that acidic peptide has good therapeutic effect on rat models of Alzheimer disease, but the mechanism still needs further exploration.OBJECTIVE: To observe whether acidic peptide can inhibit the production of N-methyl-D-aspartate receptor (NMDAR) and beta-amyloid (β-amyloid) in brain, and accelerate the production and excretion of nerve growth factor (NGF) in rats with Alzheimer disease.DESIGN: A randomized controlled animal experiment.SETTING: Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Zhengzhou University.MATERIALS: The experiments were finished in the first laboratory of Institute of Bioactive Peptide, Zhengzhou University and the Cellular Culture Center, School of Basic Medical Sciences of Zhengzhou University from March 2005 to May 2006. Seventy 10-week-old healthy male SD rats without dementia symptoms were randomly divided into 7 groups with 10 rats in each group: normal control group, model group, saline group, glutamic acid 0.3 g/kg group, acidic peptide 15, 30 and 60 mg/kg groups.METHODS: Except the normal control group, the rats in the other 6 groups were induced into models of Alzheimer disease by damaging bilateral nucleus basalis of Meynert with ibotenic acid, and then intragastric administration of glutamic acid (0.3 g/kg) was given in the glutamic acid 0.3 g/kg group, acidic peptide of corresponding dosages in the acidic peptide 15, 30 and 60 mg/kg groups, and isovolume saline in the saline group respectively, 2 mL for each time, once a day for 20 days continuously.MAIN OUTCOME MEASURES: ① The learning ability of the rats was detected with Y-maze test immediately after the end of intragastric administration, and the times of correct responses were recorded. ② After the end of learning and memory test, the head was cut rapidly to remove brain,treated with immunohistochemical staining, and gray value was scanned with Biosens Digital Imaging System to determine the contents of NMDAR,NGF and β-amyloid in the brain of rats.RESULTS: All the 70 rats were involved in the analysis of results. ①Times of correct responses in the Y-maze test were lower in the other 6groups than in the normal control group (P ＜ 0.01), but higher in the acidic peptide 30 and 60 mg/kg groups than in the model group, saline group, glutamic acid 0,3 g/kg group and acidic peptide 15 mg/kg group (P ＜ 0.01). ②The gray values of NGF in basal forebrain in the model group, saline group,glutamic acid 0.3 g/kg group and acidic peptide 15 mg/kg group were lower than that in the normal control group (69.60±2.41, 69.62±1.46, 69.62±1.46,69.73±1.87, 80.77±2.72, P ＜ 0.01); There were no significant differences between the acidic peptide 30 and 60 mg/kg groups (79.39±2.23, 80.20±1.7, P ＞ 0.05), which were higher than the other groups. ③ The gray values of NMDAR and β-amyloid in cerebral cortex in the model group,saline group, glutamic acid 0.3 g/kg group and acidic peptide 15 mg/kg group were lower than those in the normal control group (NMDAR: 81.01±1.38, 81.31±2.06, 81.37±1.39, 79.38±1.23, 69.50±1.04; β-amyloid:74.26±1.39, 74.89±8.66, 74.88±1.46, 74.16±2.48, 67.40±3.06, P ＜ 0.01),and There were no significant differences between the acidic peptide 30and 60 mg/kg groups (P ＞ 0.05), which were lower than the other groups.CONCLUSION: Acidic peptide of 30 and 60 mg/kg can obviously ameliorate the learning and memory abilities in rat models of Alzheimer disease, which may be realized mainly through up-regulating the NGF content in basal forebrain and down-regulating the NMDAR and β-amyloid contents in cerebral cortex.

Objectives To explore the decade-feature of military personnel' s psychosomatic health and Its Influence factors.Methods By random cluster sampling,a total of 11362 military personnel ( including army,navy and air-force) were tested by Chinese Psychosomatic Health Scale (CPSHS) from 80' ( n=1100),90' ( n=8000),2000' ( n =2262)then employing SPSS statistic 17.0 program for data analysis by using ANOVA,LSD multiple-comparison,and stepwise regression analysis.Results The factor of eye-ear( 80s' ( 1.17 ± 1.68),90s'( 1.19 ± 1.64 ),2000s' ( 1.12 ± 1.48 ) ) had no significant difference in three decades (P ＞ 0.05 ) ; military personnel' s respiratory system,cardiovascular system,alimentary system,bone-muscle,skin,reproductive-endocrine system,nervous system,anxiety,depression,psychotic traits,family history,mental heath,physical health,and total psychosomatic health psychosomatic health had significant differences in the three decades (P＜ 0.05 ～0.01 ).The stepwise regression analysis revealed that decade,length of military service,urban-rural,marital state had significant effect on total psychosomatic health( decade:t =- 12.452,length of military service:t =-0.024,urban-rural:t=-0.066,marital status:t=0.119,P＜0.012 ～0.000).Conclusions The level of military personnel's psychosomatic health is improved from 80' s,90' s of last century to the year of 2000; the influenced factors of military personnels' psychosomatic health are including decade,length of military service,rural-urban,and marital status.
