Objective To study the expression of EI-1 in myocardium during cerebral ischemia and reper-fusion, and to investigate the mechanism of cerebral cardiac syndrome. Method Two hundred and eight SD rats weighting 220～250 gram, were divided into three groups: sham control group (n=48), cerebral ischemia group (n=80), cerebral ischemia/reperfusion group (n=80). The area of cerebral ischemia, and the concentration of sennn ET-1 and CK-MB, and the content of myocardial ET-1 were determined in 0,6, 12,24,48,72 h after cerebral ischemia and reperfusion, and were analyzed by t-test or F-test. Results Cerebral necrosis area was ob-served at 6 h after cerebral ischemia in cerebral ischemia group, and peaked at 12 h (P>0.05). The concentra-tion of CK-MB increased gradually after cerebral ischmia, peaked at 12 h (P<0.05), and then gradually de-creased. The serum concentration of ET-1 peaked at 6 h and then gradually decreased. The content of ET-1 in my-ocardium began to increase at 6 h after cerebral ischemia, and peaked at 12 h (P<0.05). In cerebral ischemia/reperfusion group, all of cerebral necrosis size, CK-MB concentration and myocardial ET-1 concent paelced at 12 h and then gradually decreased (P<0.05). Change of ET-1 concentration in blood was similar to that in cerebral ischemia group. Compared with cerebral ischemia group, the size of cerebral necrosis reduced obviously at 24 h,48 h,72 h in cerebral ischemia/reperfusion group (P<0.05). The concentration of CK-MB in cerebral ischemia/ reperfusion group was higher than that in cerebral isehemia group (P<0.05). The peak time of myocardial ET-1 was shatened in cerebral ischemia/reperfusion group. The change of serum ET-1 was not different between two groups. Conclusions Large area of cerebral ischemia, might cause myocardial injury. ET-1 is involved in the course of myocardial injury following cerebral ischemia. Though cerebral reperfusion can protect brain,but it make myocardial injury more serious,and ET-1 might participate in this course.

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 construct the nursing assistant classification service standards based on the Activities of Daily Living (ADL) Scale, Barthel Index, so as to provide an objective basis for service management of nursing assistants.Methods:The Sun Yat-sen Memorial Hospital of Sun Yat-sen University formulated the classification service standards for nursing assistants according to the ADL Scale in June 2018. Pre-implementation group (from June 2017 to May 2018) and post-implementation group (June 2018 to May 2019) were divided according to the implementation start time. The self-designed Electronic Satisfaction Questionnaire was used to compare the satisfaction of patients and their family members, head nurses and nurses with working quality of nursing assistants, satisfaction of nursing assistants with working and the turnover rate of nursing assistants before and after implementation.Results:After implementation, the median of satisfaction score of patients and their family members on the work of nursing assistants dropped from 21 to 14, and the turnover rate of nursing assistants decreased from 59.6% to 29.0% with statistical differences ( P<0.01) . Conclusions:Application of ADL to evaluate the classification service standards for nursing assistants can improve the working quality and satisfaction of nursing assistants and reduce the turnover rate which is worthy of promotion in nursing management of nursing assistants.

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 This study aimed to develop an experimental animal platform for evaluating the feasibility and safety of intelligent acupuncture robots and to lay the foundation for further research.Methods Six 2-month-old Guangxi Bama miniature pigs were used as experimental subjects for acupuncture verification after anesthesia.First,manual acupuncture verification was carried out.Six acupoints were selected for each experimental animal and the needles were left for 20 min after the lifting,inserting,and twisting manipulation.Before and after controls were included.The experiment was carried out for 28 days,and each experiment was conducted once every 2 days for a total of 10 times.After verification of manual acupuncture,a point 10 mm from each of the six selected acupoints was selected,with a total of 12 points,and acupuncture operations were carried out on the experimental animals using the intelligent acupuncture module of the acupuncture robot at different frequencies and angles,to further verify the stability and feasibility of the animal platform.Results Routine safety-related blood indicators and blood biochemistry indicators after the procedure were normal and stable compared with those before the procedure.The average heart rate of the animals was 124 beats/min,the average blood pressure was 87/36 mmHg,and the average body temperature of was 36℃at a room temperature of 25℃,with no significant change in body temperature during and after the experiment.On the basis of this experimental platform,acupuncture manipulation using the intelligent acupuncture module of the acupuncture robot was completed successfully,with no abnormalities related to acupuncture such as bending,breaking,or stagnation of needles during the experimental process,and the experimental animals showed no obvious abnormalities.Conclusions This study established a stable experimental animal platform for evaluating the feasibility and safety of acupuncture carried out by intelligent acupuncture robots,based on the existing experimental method of miniature pigs.These result lay a foundation for further research related to the use of intelligent acupuncture robots.

Objective:To investigate the relationship between the levels of serum cytokines and chemokines and the prognosis of patients with acute B-ALL after receiving chimeric antigen receptor (CAR)-T cell immunotherapy and acute graft-versus-host disease (aGVHD) in patients after bridging allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:According to the case-control principle, Forty-two patients with B-ALL who received CD19-CAR-T cell immunotherapy bridged to allo-HSCT at Heibei Yanda Ludaopei Hospital from September 18, 2019 to May 9, 2022 were enrolled. Mann-Whitney U test was used to compare the changes of aGVHD-related cytokines and chemokine levels between CAR-T cell immunotherapy and bridging transplantation in different patients at the same time. Their plasma levels of cytokines and chemokines related to aGVHD were monitored at the day before CAR-T therapy and after CAR-T treatment at day 4, 7,14,21,28. The receiver operating characteristic curve was drawn to evaluate the predictive value of cytokines and chemokines in predicting the occurrence and the death of aGVHD patients. Kaplan-Meier method and Log-rank tests were used for Overall survival (OS) analysis. Results:Twenty-four of total 42 patients had aGVHD, of which 11 patients died and 31 patients survived. There was no significant difference in cytokines and chemokines between the aGVHD group and the non-aGVHD group on the day before CAR-T cell treatment. According to statistical analysis, the serum Elafin levels of aGVHD group was higher than that of non-aGVHD group at the 21st day [4 482 (2 811, 6 061) ng/L vs 2 466 (1 948, 3 375) ng/L, Z=3.145, P=0.001] and the 28st day [4 391 (2 808, 5594) ng/L vs 2 463 (1 658, 2 830) ng/L, Z=2.038, P=0.048] separately. At the 14th day, serum cytokines and chemokines levels between the two group were as follows,MIP-1 α [21.02 (12.36, 30.35) ng/L vs 5.56 (3.64, 10.79) ng/L], sCD25 [422.47 (257.99, 1 233.78) IU/ml vs 216.11 (133.75,457.39) IU/ml], Elafin [4 101 (2 393, 5 006) ng/L vs 2 155 (1 781, 3 033) ng/L], IL-6 [119.08 (23.97, 183.43) ng/L vs 8.39 (2.91, 17.42) ng/L] and IL-8 [13.56 (12.50, 24.52) ng/L vs 2.83 (1.73,6.87) ng/L] were at higher levels ( Z=2.653, P=0.007; Z=2.176, P=0. 030; Z=2.058, P=0.041; Z=3.329, P<0.001; Z=3.162, P=0.001). The KM survival curve showed that the cumulative survival rates of patients with higher serum levels of MIP-1α, sCD25, Elafin, IL-6 and IL-8 were lower than those with low levels at day 14, and the difference was statistically significant (χ 2=12.353, 4.890, 6.551, 10.563, 20.755, P<0.05). Conclusion:The outcomes of patients treated with CAR-T cell therapy bridged to allo-HSCT was correlated with serum MIP-1α, sCD25, Elafin, IL-6 and IL-8 levels after receiving CAR-T therapy. High concentrations of MIP-1α, sCD25, Elafin, IL-6 and IL-8 suggest poor prognosis and can be used as biomarkers to suggest appropriate clinical selection of therapy.

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.
