Objective To discuss the relationship among Big Five-Personality, Resilience and General Health of the new recruits in a certain troop. Methods 205 new recruits completed the questionnaires, which include NEO Five-Factor Inventory ( NEO-FFI) , Connor-Davidso Resilience Meter (Chinese version) , and General Health Questionnaire (GHQ-12). Results The neuroticism trait of personality positively correlated to General Health( r = 0.50, P<0.001) and significantly predicted mental disease (β =0.4, P<0.01). The self-strengthening dimension of resilience was negatively related to general health ( r = - 0. 51 , P<0. 01 ). Furthermore, self-strengthening played partial mediating role between neuroticism and general health ( Sobel Z =2. 92, P<0. 01). Conclusion The neuroticism trait of personality is a risk factor for new recruits'mental health, while self-strengthening is a protective factor for it.

Objective:To determine the curative effect of Ginkgo Biloba extract on the back chapped skin in SD rats. Methods:Totally 60 SD rats were randomly divided into 6 groups with 10 rats in each. One group was the blank control group, while the other five groups with the same back chapped skin were respectively treated with different therapy regimen, namely one group was the model group without any treatment, one group was urea group treated with the commercially available urea, and the last three groups were re-spectively treated with Ginkgo Biloba extract at the dose of 5%, 1% and 0. 2%. The pathological tissue was observed after HE stai-ning, and the content of hydroxyproline ( Hyp) in skin was determined by alkaline hydrolysis. Results:The skin lesion and the score of pathological section were studied and the content of Hyp in the damaged skin was determined. The comprehensive score for the groups was 0, 13. 2, 7. 4, 11. 0, 5. 8 and 6. 6, respectively, and the content of Hyp was (4. 57 ± 0. 07), (2. 41 ± 0. 27), (3. 29 ± 0.57), (2.55 ±0.31), (3.24 ±0.26) and (3.37 ±0.24) μg·mg-1,respectively. There was significant difference in the curative effect between the Ginkgo Biloba extract groups at high dose (5%) and medium dose (1%) and the model group (P<0. 05), which showed no obvious difference when compared with the urea group (P>0. 05). Conclusion:The extract of Ginkgo Biloba has a certain effect on the back chapped skin in SD rats, which may contribute to the external preparations of Ginkgo Biloba extract.

Objective To explore the relationship between big-five personality,and public mood of volunteers,and to find out the moderator effect of justice sensitivity.Methods A total of 1 022 volunteers were investigated.The Big-Five Inventory (BFI),Public Mood Scale (PMS),Justice Sensitivity Inventory (JSI) were applied to all subjects.Results The average score was (19.77±4.49) for extraversion,(26.69± 4.13) for agreeableness,(23.33±5.37) for conscientiousness,(12.49±4.91) for neuroticism,(24.95±5.44)for openness,(8.78±3.23) for positive public mood,(3.46±3.06) for negative public mood and correlated with (26.85± 10.55) for observer sensitivity.The extraversion,agreeableness,conscientiousness and openness were correlated with positive public mood(β=0.31,P＜0.01;β=0.25,P＜0.01;β=0.29,P＜0.01;β=0.26,P＜0.0 1),and negatively correlated with public mood (β=-0.14,P＜0.01;β=-0.29,P＜0.01;β=-0.20,P＜0.01;β=-0.08,P＜0.01).Neuroticism was negatively correlated with positive public mood (β=-0.27,P＜0.01),and positively correlated with negative public mood (β=0.31,P＜0.01).The interaction effect of agreeableness and observer sensitivity negatively correlated with positive public mood,negative public mood (β=-0.09,P＜0.01;β=-0.07,P＜0.05).The interaction effect of neuroticism and observer sensitivity was positively correlated with positive public mood (β=0.08,P＜0.01).Conclusion Observer sensitivity plays a regulative role between big-five personality and mental health,and can slow the negative impact of low agreeableness to positive public mood,strengthen the impact of low agreeableness to negative public mood,and slow the negative impact of high neuroticism to positive public mood.

3T3-L1 adipocytes were cultured and differentiated into mature adipocytes in vitro. The adipocytes were intervened by ACAT inhibitor( 2 μg/ml) and ox-LDL with various concentrations (0,25,50,75,and 100 μg/ml)for 48 h,ACAT inhibitor( 2 μg/ml) and ox-LDL( 50 μg/ml) at the 0,6,18,36,and 48 h,or ACAT inhibitor( 2 μg/ml),ox-LDL( 50 μg/ml),and TUDCA with various concentrations(0,100,200,and 400 μ mol/L)for 48 h,respectively.The levels of visfatin in supernatant were examined by ELISA and the expressions of protein GRP78 and CHOP in adipocytes were detected by Western blot.After the adipocytes were treated with ACAT inhibitor and ox-LDL at different concentrations for 48 h,the cholesterol concentration and the expressions of GRP78 and CHOP protein in adipocytes and the visfatin levels in the supernatant fluid were increased with the increase of the ox-LDL concentration.The differences had statistical significance in the experimental groups compared with blank control group( all P＜0.05 ).After the intervention with ACAT inhibitor and ox-LDL for different durations,the expressions of GRP78 and CHOP protein in adipocytes and the visfatin levels in the supernatant fluid were up-regulated in a timedependent manner.The differences between experimental groups and blank control had statistical significance( all P＜0.05 ).After the intervention with ACAT inhibitor,ox-LDL,and different concentrations of TUDCA for 48 hours,the expressions of GRP78 and CHOP protein in adipocytes and visfatin levels in the supernatant fluid were down-regulated in a dose-dependent manner and as compared with blank control group the difference were statistically significant( all P＜ 0.05 ).The increase of cholesterol load in adipocyte may promote the visfatin secretion,denoting that the mechanism might be due to the enhancement of endoplasmic reticulum stress in aidpocytes.

BACKGROUND: Nowadays complex bone defects have become a great challenge to orthopedists. A synergistic contribution of various growth factors and a crosstalk between their signaling pathways have been suggested as determinatives for the overall osteogenic outcome.OBJECTIVE: To develop calcium phosphate cement (CPC) incorporated with γ-polyglutamic acid/carboxymethyl chitosan (PGA/CMCS), and to evaluate its physical and chemical properties and sustained-release function. METHODS: The γ-PGA/CMCS polymer composites were prepared by graft copolymerization and spray freeze drying methods, and then loaded with recombinant human bone morphogenetic protein 2 (rhBMP-2) growth factor. CPC served as control group, and γ-PGA/CMCS-CPC containing different contents of rhBMP-2 as experimental groups. A γ-PGA/CMCS-CPC scaffold with regular blade-like crystalline structure was fabricated by injection compression molding. Before mixed with the liquid phase, the solid additives were properly mixed by wet method of CPC solid and the γ-PGA/CMCS carrier, then the pre-blended mix was freeze-dried. The setting time and compressive strength of bone cement in each group were detected, and the microstructure of the material surface was observed under scanning electron microscopy. In vitro release of rhBMP-2 was investigated. The effect of bone cement extracts on cell proliferation was determined through MTS assay.RESULTS AND CONCLUSION: γ-PGA/CMCS-CPC had the same physicochemical properties to the CPC. Initial and final setting time, compressive strength of bone cement had no significant differences among groups. The scanning electron microscope results showed that the γ-PGA/CMCS-CPC scaffold was covered by regular blade-like crystalline structure and the γ-PGA/CMCS particles were uniformly dispersed in the CPC crystals. A sustained release of rhBMP-2 was observed from the γ-PGA/CMCS-CPC. The cell experiments exhibited that the samples with regular blade-like crystalline structure had better cell response compared to CPC control groups with irregular crystalline structure. These findings indicate that γ-PGA/CMCS-CPC can maintain good physicochemical properties, and release growth factor or drug to promote bone formation.

Objective To investigate the distribution and antimicrobial resistance of the clinical isolates from Children's Hospital of Chuzhou during 2014.Methods A retrospective analysis was conducted with the bacterial strains isolated from various clinical specimens in 2014.Results A total of 382 clinical isolates were collected during 2014, of which gram positive organisms and gram negative organisms accounted for 37.4 % and 62.6 %, respectively. The top 5 most frequently isolated microorganisms were E. coli (18.8 %),K. pneumoniae (16.8 %), coagulase negative Staphylococcus (13.1 %),S. pneumoniae (9.4 %) and S. aureus (9.2 %). The prevalence of MRSA was 28.6 % in S. aureus and the prevalence of MRCNS was 76 % in CNS. All staphylococcal strains were susceptible to daptomycin, linezolid and vancomycin. All the E. faecalis and E. faecium isolates were sensitive to daptomycin, linezolid and vancomycin. All the S. pneumoniae strains were susceptible to penicillin. The prevalence of extended spectrum-lactamases (ESBLs) positive strains was 58.3 % in E. coli and 28.1 % in K. pneumoniae. The Enterobacteriaceae strains were highly sensitive to carbapenems. Only 3 (1.6 %) carbapenem-resistant strains were identified in the Enterobacteriaceae isolates. About 13.3 % and 6.7 % of theP. aeruginosa isolates were resistant to piperacillin and levofloxacin, respectively. All the P. aeruginosa strains were sensitive to the other antimicrobial agents. The percentage of carbapenem-resistantAcinetobacter strains was lower than 10 %. Only one carbapenem-resistant A. baumannii strain was identified.Conclusions Gram negative microorganisms account for most part of the clinical bacterial isolates in 2014. The antimicrobial resistance is still very serious in this hospital, especially the emergence of carbapenem-resistant Enterobacteriaceae, which is of great concern.
