objective To identify the three strains of pink-pigmented bacteria isolated from ticks.Methads 16S rDNA sequence analysis,16S rDNA similarity searching,bacterial morphological,physiological and biochemical tests and fatty acids analysis were used.Results The bacterial strains were pinkpigment,gram negative,strictly aerobic coccobacillus.They grow optimally at 37℃,while not in the presence of≥5% NaCl.The tests showed positive result for urease,D-glucose,citrate,UV absorption,and catalase.The predominant fatty acids were C16:0,C17:0,C18:1 ωgc and C19:0 cyc.Comparative 16S rDNA sequences analysis revealed that the strains were closely related to Roseomonas cervicalis and could reach up to 99.1% identity.Conclusion Based on phenotypic,biochemical and phylogenetic data,we propose these three isolates represent distinct species in genus Roseomonas,of which ticks may serve as a potential vector.

Objective To investigate the quality of life of army recruits in their basic military training period,and to analyze the influence of job burnout and work satisfaction on their quality of life.Methods A total of 625 recruits enrolled in 2014 of Xinjiang Army troop were chosen as subjects in this study by stratified cluster random sampling.Quality of life was assessed by Chinese version SF-36(Short-Form Health Survey Scale),job burnout was assessed by Chinese version Maslach Burnout inventory general survey (MBI-GS) and work satisfaction was assessed by Chinese version Minnesota Satisfaction Questionnaire (MSQ).Results The scores of PCS and MCS about 597 recruits were (85.93±12.62) and (81.10±14.12) respectively.According to demographic characteristics,the score of physiological function was lower than that of non-smoking group (t=2.009,P＜0.05),the score of role physical was lower than that of non-smoking group (t=2.617,P＜0.05),and the score of PCS was lower than that of non-smoking group (t=2.141,P＜0.05).As to except reported health transition,there were negative correlations between emotional exhaustion,depersonalization and other SF-36 scales (r=-0.344～-0.661,P＜0.01) respectively.There were negative correlations between personal accomplishment and vitality (r=-0.204,P＜0.05),role emotional (r=-0.239,P＜0.05),mental health (r=-0.289,P＜0.05) and MCS (r=-0.276,P＜0.05) respectively.Work satisfaction and quality of life was positively correlated (r=0.243～0.635,P＜0.01).As to the independent variable,regression analysis showed that emotional exhaustion (β=-4.732,P＜0.01),Minnesota external satisfaction (β=0.783,P＜0.01) influenced PCS,the difference was statistically significant.Emotional exhaustion(β=-6.534,P＜0.01),pre-enlistment place of residence (β=-5.319,P＜ 0.05),Minnesota external satisfaction (β=0.813,P＜0.01)influenced MCS,the difference was statistically significant.Conclusion Job burnout and work satisfaction influence the quality of life about the army recruits,the more job burnout signify the lower quality of life,and its influence on mental health is more significant.The higher work satisfaction signify the higher quality of life.

Objective To study the co-infection of tick-borne pathogens in Ixodes persulcatus collected in Charles Hilary,Xinjiang Uygur autonomous region (Xinjiang).Methods Ticks were collected by flagging in grassy areas in Charles Hilary,Xinjiang from June 2012 to June 2013.The 5S-23S rRNA intergenic region from Borrelia (B.) burgdorferi,16S rRNA gene from Anaplasma,ompA gene from spotted fever group Rickettsia,comI gene from Coxiella (C.) burneti and Nss-rRNA gene from Babesia were amplified with nested polymerase chain reaction (nested PCR),respectively.Results Among 204 lxodes persulcatus,104 were positive for tick-borne pathogens with the positive rate of 50.98％,and among them the positive rates of B.burgdorferi,spotted fever group Rickettsia and Anaplasma phagocytophilum were 34.31％ (n =70),28.92％ (n =59),9.31％ (n =19),respectively.And no C.burnetii and Babesia were detected.The overall co-infection rate was 19.12％ (39/204),the co-infection rate was 16.18％(33/204) for B.garinii and spotted fever group Rickettsia,4.90％ (10/204) for B.burgdorferi and Anaplasma phagocytophilum,2.94％(6/204) for spotted fever group Rickettsia and Anaplasma phagocytophilum and 2.45％ (5/204) for B.burgdorferi,Anaplasma phagocytophilum and spotted fever group Rickettsia.Conclusion The results indicated that the natural co-infections of B.garinii,B.afzelii,Anaplasma phagocytophilum and spotted fever group Rickettsia existed in Charles Hilary Ixodes persulcatus collected in Xinjiang.

Objective: To investigate the fatigue status of military personnel stationed in plateau and high cold region, and to analyze the mediator effect of trait coping style on job stress and fatigue. Methods: In October 2010, with the method of cluster random sampling survey, 531 military personnel stationed in plateau and high cold region were chosen as subject. The fatigue status were evaluated by the Chinese version multidimensional fatigue inventory (MFI-20) , job stress were evaluated by the Job Stress Survey (JSS) , and trait coping style were evaluated by the Trait Coping Style Questionnaire (TCSQ) . Results: According to the information of different population characteristics, mean rank of physical fatigue about the urban (town) group were higher than that of rural group (Z=-2.200, P<0.05) ; mean rank of reduced motivation about the urban (town) group were higher than that of rural group (Z=-2.781, P<0.05) ; mean rank of general fatigue scores about the urban (town) group were higher than that of rural group (Z=-3.026, P<0.05) ; mean rank of physical fatigue about the up or equal 20-years old age group were higher than that of below 20-years old age group (Z=-4.045, P<0.05) ; mean rank of reduced motivation about the up or equal 20-years old age group were higher than that of below 20-years old age group (Z=-2.182, P<0.05) ; mean rank of mental fatigue about the up or equal 20-years old age group were higher than that of below 20-years old age group (Z=-2.879, P<0.05) ; mean rank of general fatigue scores about the up or equal 20-years old age group were higher than that of below 20-years old age group (Z=-3.647, P<0.05) ; mean rank of reduced motivation were significant statistical difference among the military officers, sergeancy and soldier group (F=18.965, P<0.05) ; mean rank of general fatigue scores were significant statistical difference among the military officers, sergeancy and soldier group (F=14.711, P<0.05) . The score of negative coping style were positively correlated with the score of physical fatigue (r_s=0.129) , reduced activity (r_s=0.123) , reduced motivation (r_s=0.149) and general fatigue (r_s=0.174) respectively, the score of organizational support lack strength were positively correlated with the score of physical fatigue (r_s=0.090) , reduced activity (r_s=0.098) , reduced motivation (r_s=0.099) and general fatigue (r_s=0.130) respectively. The mediator effect of negative coping style on the job stress and fatigue was 0.013 (P<0.01) . Conclusion The fatigue statuses of the urban (town) group and the up or equal 20-years old age group are poor, and the negative coping style plays mediator effect on the job stress and fatigue.

Objective To explore the effects of job content on psychological stress in young recruits.Methods In October 2014,625 young recruits enrolled in one troop of Xinjiang Military Command in 2014 were chosen as subjects by multi-stage stratified random sampling.The Chinese version of the job content questionnaire (JCQ) and the psychological stress self evaluation test (PEST) were used to investigate the subjects.The subjects were divided into two groups with scores higher and lower than the mean score of three subscales (job requirement,degree of autonomy,and social support) of JCQ to explore the effects of job content on psychological stress in young recruits.The correlation of psychological stress with three subscales of job content was evaluated using the Pearson's correlation analysis.Binary logistic regression analysis was used to analyze the influencing factors for psychological stress.Results The PEST score of young recruits was 49.98± 9.98.Forty-five (7.68％) out of them had scores of ≥70 points and were diagnosed with high levels of psychological stress.When the subjects were grouped based on socio-demographic characteristics,a high level of psychological stress was significantly more frequent in subjects less than 20 years of age than in those not less than 20 years of age,in smoking subjects than in non-smoking subjects,and in urban residents than in rural residents (10.42％ vs 5.03％,P＜0.05;10.14％ vs 5.33％,P＜0.05;10.85％ vs 5.88％,P ＜0.05).There were no significant differences in educational level or identity before recruitment between subjects with different levels of psychological stress (P＞0.05).In various job content domains that had impacts on psychological stress,subjects with a low score of social support had significantly higher PEST scores than those with a high score of social support (50.96±10.35 vs 48.49±9.22,P＜0.01).The PEST score was negatively correlated with the degree of autonomy and social support(r=-0.103,P＜0.05;r=-0.239,P＜0.05).The results of logistic regression analysis showed that job requirement and social support were influencing factors for psychological stress (OR =0.718,95％CI=0.718 (0.607～0.851),P＜0.05;OR=1.185,95％CI=1.185 (1.087～1.292),P＜0.05).Conclusion Psychological stress of young recruits in army is not optimistic.Psychological stress is weakly negatively correlated with social support.The low scores on job requirement subscale and social support subscale may be potential protective factor and risk factor for psychological stress,respectively.
