Objective;To explore the regulative effect of perceived social support between personality and mental health.Methods;With Perceived Social Support Scale,NEO Five Factor Inventory and General Health Questionnaire-GHQ 20,1800 college students from 9 Hunan colleges and universities were inverstigated.Results;①Significant positive correlation existed between the factors of GHQ-20 and NEO-N,while significant negative correlation between the factors of GHQ-20 and NEO-E,NEO-C and all factors of perceived social support;perceived social support and its factors had significant negative correlation with NEO-N,while significant positive correlation with NEO-E and NEO-C.②There was significant interaction effects between perceived social support and personality existing in mental health.Conclusion;Students' perceived social support play a regulative role between personality and mental health.

OBJECTIVE To investigate the factors that result in lower respiratory tract infection by Candida albicans and the situation of drug resistance in geriatric inpatients.METHODS Clinical samples were collected from the geriatric inpatients with lower respiratory tract infection in our hospital from Jan 2004 to Dec 2006,and among them,146 patients were found containing C.albicans in their sputum.Meanwhile retrospective analysis was made.RESULTS There were many factors resulting in lower respiratory tract nosocomial infection by C.albicans in geriatric inpatients,and the detection rates of C.albicans increased year by year in the past three years were 25.2%,36.9% and 39.9%,respectively.The drug resistance of C.albicans raised obviously at the same time was 20.6%,41.8% and 34.2%,respectively.CONCLUSIONS It is necessary for reducing lower respiratory tract infection rates to efficiently control the C.albicans infection factors and to properly use antibiotics.

Objective To investigate the etiologic roles of apoptosis-associated genes,environmental factors and their interactions in lumbar disc herniation (LDH).Methods A case-control trial was conducted.We recruited 128 outpatients with LDH as case group and 132 normal people matched by age and gender as control group.Peripheral venous blood samples were collected and DNA was extracted from leukocytes.By using a modified Brucker Autoflex MALDI-TOF mass spectrometer,we analyzed 3 genes with 9 polymorphic sites,namely,Fas-1377G/A rs2234767,Fas-670G/A rs1800682,Fas rs2147420,Fas rs2296603,Fas rs7901 656,Fas rs1 57101 9,FasL-844C/T rs7631 10,CASP-9-1263A > G rs4645978,and CASP-9-712C > T rs4645981.The correlations between polymorphism of Fas,FasL and CASP-9 genes and the risk of LDH were evaluated by non-conditional Logistic regression model.Multiple Logistic regression model was performed to assess the interaction between apoptosis-associated genes and environment factors,such as lumbar vertebral loads,bed type,spare-time exercises and spare-time activities. Results There were preferable balances in case and control groups in age and gender without significant differences.However,the two groups differed significantly (P <0.05)in lumbar vertebral loads,body mass index, bed type, spare-time exercises and spare-time activities. Correlation analysis showed remarkable correlations between LDH and the polymorphisms of FasL-844C/T (rs7631 10)and CASP-9-1263A>G (rs4645978),and FasL-844C/T TT and CASP-9-1263A>G GG genotypes might be the high risk genotypes of LDH.The gene-environment interaction analysis revealed that super-multiplicative and sub-multiplicative interactions respectively between FasL-844TT genotype and lumbar vertebral loads (3-4 level),and between CASP-9-rs4645978 GG and lumbar vertebral loads (3-4 level).Conclusion FasL,CASP-9 genes and lumbar vertebral loads and their interactions play important roles in the pathogenesis of LDH.It suggests that the risk of LDH may be codetermined by environmental factors and inherited susceptibility genes,and that the mechanisms of interactions vary in different genotypes and the same or different environmental factors.
