Objective: To investigate prevalence of neurosis in a college of central China. Method:4465 college students were investigated by epidemiological method used in the national survey of 12 areas 10 years before. Result: The present prevalence of neurosis in students were 9.34%, higher than that of the national survey 10 years before (6.44%). In different diagnoses, the present prevalence of anxiety disorder was much higher. Male students had higher rate of neuroses than female, those in grade 3 or 4 had higher rate of neuroses than those in other grades. The most obvious invoke factor of neurosis was lovelorn. Conclusion: The prevalence of neurosis is higher than 10 years before.

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.

Objective To study the state of doctors' psychological capital in public hospitals,and to analyze the characteristics of such capital,so as to better leverage the capital as a hospital management tool.Methods A quantitative and qualitative research was made on the state of doctors＇ psychological capital.Results The doctors' task-oriented psychological capital scored 4.25,and guanxi-oriented psychological capital 4.41; “modesty and prudence”scored the highest in all dimensions of the doctors' psychological capital,“optimism and hope”lowest; the doctors with different genders,ages,seniority,and monthly average income have a difference in psychological capital.However,no significant difference was found with varying titles,hospital levels,and employment models.Conclusion The doctors were found with a strong psychological capital to cope with stress.Better psychological capital will raise quality of care in practice.
