Analysis of SCL-90 test results of 809 physical examinees / 重庆医学

Objective To explore the mental health status of physical examination population,and provide the basis for mental health guidance.Methods The SCL-90 scale in the cloud service system of PEM was used to evaluate the gender, marriage, age, education, income and other factors in the physical examination cases of our hospital.Results The positive rate of SCL-90 in 809 patients was 27.94%.Female scores,and the scores of somatization, obsessive-compulsive symptoms, depression, anxiety, terror of women were higher than those of men except paranoid.Unmarried population scores and the scores of all factors were higher than those of married and divorced people.The scores of all factors in the 18-<30 year-old cases was the highest among all cases;the scores of depression,hostility and paranoid was decreased with the increase of age;the score of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, anxiety, terror,spirit of 50-60 year-old cases were the lowest among all cases.The higher the degree of education,and the more economic income, the lower the psychological evaluation of each factors scored.Conclusion The mental health problems of female,unmarried,low age,low education,low-income groups are grim.

Effects of psychological stress on in vitro expression of activated surface molecules on T cells of peripheral blood from healthy persons / 中国病理生理杂志

AIM: To study cellular and molecular mechanism involved in increasing susceptibility of infection in psychological stress persons. METHODS: Comparative studies were performed with double staining and flow cytometry analysis on immunophenotyping and in vitro expression of early activating surface molecule CD69 in response to mitogens on T cells from peripheral blood of 20 healthy college student volunteers before and after psychological stress. A series of term final examinations was defined as psychological stress. RESULTS: Immunophenotyping analysis showed no statistically significant difference in the percentage of CD2, CD3, CD4, CD8, CD19, CD20, CD16 and CD56 positive lymphocyte populations before and after psychological stress. There was a statistically significant decrease in the in vitro expression of CD69 in response to polyclonal stimulators on the T cells from persons after psychological stress than those before psychological stress. The percentage of CD69 expression (CD69+CD3+/CD3+%) in response to PHA and PDB in the whole blood culture for 72 hours decreased respectively from 28.1?4.1 and 80.7?6.8 on the T cells obtained before psychological stress to 17.6?3.8 and 65.8?7.9 on those obtained after psychological stress, while there was no statistically significant difference between the CD69 expression rates without stimulators on the T cells obtained before and after psychological stress. CONCLUSIONS: The effects of psychological stress to immune system is not on the level of changing proportions of the sub-populations within peripheral blood lymphocytes. Psychological stress can decrease the activating response of T cells in healthy persons, which may be responsible for the increase of susceptibility to infection in the psychological stress persons.
