Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

In this study,the common critical medical cases were organically combined with SimMan simulation system,which enabled students to deeply understand the diagnosis,treatment of disease and clinical operation as consulting real patients.Also,it could improve their clinical thinking ability,clinical skills and operational level.

Objective To study the effects of resilience training on work fatigue,psychological stress and mental health in warship soldiers.Methods100 warship soldiers were selected and divided randomly into training-group (n=45) and control group (n=55),and the training group was divided into two groups by casting lots ( n t =22,n 2 =23 ).The shedding rate of the training group was 13％ (6 out of 45 ),while the control group was 10％ (5 out of 50).All of them were tested by the Resilience Scale for Adults ( RSA),Newly Developed Questionnaire for Work Related Fatigue Feelings (WRFFQ),Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90) before and after training.According to resilience theory and its elements to design the group-training,10 times resilience training was arranged 2 hours once per week for the training group.The aim was to train members' self-awareness,emotion management,interpersonal communication,problem solving and social support and other capabilities.Before training there were no significant differences between the training-group and control-group in age,military service,job and education level and total average score of RSA,WRFFQ score,PSET standard scores and the SCL-90 total average score (P＞ 0.05 ).Results ①Compared with the pre-test resuits,the RSA ( 2.90 + 0.47) scores of training-group ( n =39) significantly increased after training,but the scores of WRFFQ(33.62 ± 11.24),PSET(47.80 ±9.09) and 5CL-90( 1.14 ±0.09) significantly reduced (P＜0.05) ;For control group ( n =50),no significant differences were found in scores of RSA (2.56 + 0.57 ),WRFFQ (42.38± 17.76),PSET( 53.70 ± 13.25) and SCL-90( 1.43 ± 0.45 ) (P＞0.05 ) ; ②Compared to the control group,posttest scores of RSA significantly increased,but the scores of WRFFQ,PSET and SCL-90 significantly decreased for the training-group(P ＜ 0.05).Conclusion Resilience training can effectively improve warship soldiers' resilience,increase their anti-stress ability and mental health level and reduce fatigue symptoms.

OBJECTIVETo analyze the polymerase gamma(Polg) gene polymorphisms in Chinese idiopathic infertile males and evaluate the correlation of the polymorphisms with male infertility.

METHODSWe conducted a study of Polg CAG repeats in the sperm or blood DNA of 55 asthenospermia patients, 57 oligospermia patients, 34 azoospermia patients, and 104 controls with PCR and GeneScan. Phenotypic data were available in all the subjects, including semen parameters, and clinical profiles.

RESULTSThe frequency of 10/not 10 CAG genotype in asthenospermia patients was higher than in the other groups, but with no significance.

CONCLUSIONOur findings have shown for the first time that there exits an ethnic difference between Chinese and European males in the number of CAG repeats of Polg gene, and that 10/not 10 CAG genotype may affect sperm motility.

Objective To explore the safety of collection of peripheral blood stem cells(PBSCs) from low-weight infants with osteopetrosis(OP) and its clinical significance. Methods One case of low-weight infants with OP received PBSCs collection using a continuous-flow blood cell separator,and the safety of collection process was observed.The amount of monocyte cell(MNC) and CD34+ cell were noted and its clinical significance was analyzed.Results Low-weight infants with OP could tolerate collection process,the number of collection MNC and CD34+ cells were 10.06?108/kg,2.74?106/kg.Conclusion Adequate PBSCs can be collected from OP who need not be mobilized,thus can offer backup for graft failure.PBSCs collection from low-weight infants is safe.

Objective To observe the clinical efficacy of transplantation with autologous bone marrow mesenchymal stem cells (MSCs) in the treatment of children with severe mental retardation (MR). Methods Fifty children with severe MR (2-6 years old), admitted to our hospital from May 2008 to December 2009, were chosen; self-control observation on the mental and motor developments of these children in the same length of time periods was performed 6 months before and 6 months after the autologous bone marrow MSCs transplantation. Meanwhile, the improvements of each patient were followed up and analyzed 1, 3 and 6 months after the transplantation. Results Two patients failed in the culture of bone marrow MSCs; 6 patients failed in follow-up; the other 42 were observed completely.Significant improvement was noted in 25 patients after the transplantation with an effective rate reaching 59.5%; gradual mental and motor improvements appeared in these 25 patients 1 month after the transplantation, and lasted till the 6th month of transplantation. The average scores of mental improvement were (4.67±4.20) in 6 months before transplantation, and (17.12±13.05) in 6 months after transplantation (t=6.816, P=0.000). The average times having gross motor improvement 6 months before and 6 months after transplantation were (1.019±0.78) and (1.15±0.91), respectively (t=1.610, P＞0.05); the average times having fine motor improvement were (0.89±0.79) and (3.40±3.16) months in 6 months before and 6months after transplantation (t=5.030, P＜0.05); the average times having language improvement were (0.99±0.95) and (3.23±3.30) months in 6 months before and 6 months after transplantation (t=4.000, P＜0.05); the average times having personal-social behavior progress were (1.03±0.81) and (2.95±3.68)months in 6 months before and 6 months after transplantation (t=3.509, P＜0.05); the average times having adaptive behavior progress were (0.88±1.22) and (1.19±1.48) months in 6 months before and 6 months after transplantation (t=1.322, P＞0.05). Conclusion Autologous bone marrow MSCs transplantation can improve the intellectual development in a short time, mainly in the fine motor, language and personal-social behavior, in children with severe MR. Bone marrow MSCs transplantation for severe MR is safe and effective in a short-term.

OBJECTIVETo evaluate the effects of mixed grafting of allogeneic PADM and autologous STS on wound healing of full-thickness defect in rats.

METHODSFull-thickness defects with size of 6 cm x 4 cm were produced on the back of 12 SD rats, and they were divided into E group (n = 6) and C group (n = 6) according to the random number table. The wounds in E group were grafted with a mix of allogeneic PADM (expansion rate 10: 5) and autologous STS with thickness of 0.2 mm, while those in C group were grafted with autologous STS in the same thickness. The wound healing rate, survival rate, contraction rate, and expansion rate of transplanted skin were observed at post operation week (POW) 2, 3, 4, 6, 8, 12, 20. Tissue samples form wounds and surrounding normal skin were harvested at POW 20 for histopathological observation as follows. The structure of collagen fiber bundle was observed by HE staining, the diameter and gap rate of collagen fiber bundle were also measured. The distribution of type I and III collagen was observed by sircus red staining, and the contents of type I, III collagen and their ratio were also examined. Data were processed with independent samples t test, Levene test, and t' test.

RESULTSSurvival rate of transplanted skin in E group at POW 2 [(76.1 +/- 13.1)%] was obviously lower than that in C group [(94.5 +/- 1.3)%, t' = 3.440, P = 0.018]. Contraction rate of transplanted skin in E, C groups at POW 3 showed significant difference [(34 +/- 8)% vs. (16 +/- 12)%, t = -3.211, P = 0.009]. Compared with those in peri-wound normal skin, collagen fiber bundles in C group showed signs of homogenization, and collagen fibers were thin with irregular arrangement. Collagen fiber structure and arrangement of composite skin in E group were similar to those surrounding normal skin with incomplete degradation of PADM. Diameter of collagen fiber bundle [(9.6 +/- 0.8) microm], gap rate between collagen bundle [(24 +/- 5)%], content of type I collagen [(80.2 +/- 5.4)%] and the ratio of type I to type III collagen (4.3 +/- 1.2) in E group were all increased as compared with those in C group [(7.3 +/- 1.4) microm (t = -3.562, P = 0.005), (17 +/- 4)% (t = -2.760, P = 0.020), (68.1 +/- 8.4)% (t = -2.981, P = 0.014), 2.3 +/- 1.0 (t = -3.204, P = 0.009)], while content of type III collagen [(19.8 +/- 5.4)%] in E group was lower than that in C group [(32.0 +/- 8.4)%, t = 2. 981, P = 0.014]. Above-mentioned indexes of collagen in wound of E group were similar to those of normal skin surrounding the wound.

CONCLUSIONSAllogeneic PADM used as dermal regeneration template is beneficial in improving collagen fiber bundle structure in dermis layer of rats with full-thickness skin wounds when repaired with autologous STS, and it accelerates maturation of regenerative dermal tissue.
