Objective To analyze the reliability and validity of the core competence scale A for military personnel.Methods Three thousand and five hundred healthy soldiers volunteered to complete the core competence scale A for military personnel,and data were analyzed by AMOS7.0 and SPSS16.0 program.Results The confirmatory factor analysis for structure validity of all factors showed that 11 items with higher cross loading should be deleted according to its modified index,thus the revised scale was composed of 7 factors,21 competence components,65 items and one added lie subscale.Furthermore,the theoretical model of the scale was supported by the sample data,and the fit indexes,uch as GFI,AGFI,NFI and CFI of total scale,were all over 0.9,and RMSEA was lower than 0.08.In addition,the standardized factor loadings of all competence components were 0.393-0.791(P

Objective To formulate the Psychological Core Diathesis Scale for Military Personnel(Part B),and examine the reliability and validity of the scale.Methods Following the psychometric principles,a five factors model of general cognitive ability was firstly constructed by theoretic analysis.The items of initial scale were then developed,followed by repetitive revision and screening for the final establishment of the Psychological Core Diathesis Scale for Military Personnel(Part B),which was composed of 5subtests and 25 items.One thousand and two hundred healthy soldiers were chosen by randomized cluster sampling to participate in the measurement,and 1143valid questionnaires were analyzed for item analysis,Cronbach'?coefficients,split-half reliability and construct validity.Four weeks later,50out of the 1143soldiers were retested for evaluation of the test-retest reliability.Another 200soldiers were randomly collected for the measurement of Intelligence Test for Military Personnel(Part B)as well as the Psychological Core Diathesis Scale for Military Personnel(Part B).The correlation between the results obtained from the 2scales was then analyzed.Soldiers were comprehensively evaluated by their squad leader according to uniform standard.Finally,the top soldiers and ordinary soldiers(50each)were selected by 20 squad leaders from the 1143valid subjects,the scores of the 2groups of soldiers on Psychological Core Diathesis Scale for Military Personnel(Part B)were then compared.Results Item analysis indicated that the average difficulty index of subtests ranged from 0.44to 0.80,the discriminatory power from 0.31to 0.50,and the test-retest correlation coefficient between total scale and subtests from 0.6253 to 0.9558(P

Objective To study the tooth germ development of mouse molar in fluorosis.Methods We established an acute fluorosis model and used HE-staining after preparing specimens of different stage of mouse first molar developing tooth germ.Results The developing molars of the control fetuses were at the bell stage of odontogenesis,whereas those of the experimental population were at cap stage.The ameloblasts became shorter and lost polarity.The arrangement of ameloblasts fell into disorder at the bell of differeiational stage and secretory stage.Conclusion The developing molars of the experimental fetuses were retarded.High-dose fluoride has a strong effect in the ameloblasts at the bell of differetiational stage and secretory stage.

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.

Objective To evaluate the safety and efficacy of endoscopic ultrasonography(EUS) guided ethanol ablation in patients with insulinoma. Methods The data of 10 patients with insulinoma trea-ted at the First Affiliated Hospital of Guangxi Medical University from December 2013 to January 2015 were prospectively analyzed. Results The patients were given EUS-guided ethanol ablation with dose of 0. 10 to 2. 00 ml(average 0. 70 ± 0. 62 ml)in pancreatic lesions for 15 times. No complications were observed dur-ing and after the procedure. The blood glucose improved after the procedure[4. 8(3. 9-5. 5)mmol/ L VS 2. 4 (1. 9-2. 5)mmol/ L,P < 0. 05]and the serum insulin level significantly decreased[83. 7(40. 1-143. 5) pmol/ L VS 177. 3(66. 5-200. 6)pmol/ L,P<0. 05]. The average hospital stay was(4. 3±1. 5)days. The patients were followed up for 6-12 months. EUS indicated that the echo of pancreatic lesions changed from high to low. CE-EUS revealed low enhancement and lack of blood supply. Conclusion EUS-guided ethanol ablation may become a promising minimally invasive treatment for insulinoma because of its safety,efficacy and low price.
