ABSTRACT
Objective:To investigate the current status of health checkups and the management willingness of post-test abnormal values in residents of mega communities, and to explore the factors affecting the demand for health management of abnormal values after examination.Methods:A cross-sectional study. The residents of Huaguoyuan Community in Guiyang City were enrolled as the objects of this surveywith stratified systematic sampling method and questionnaire survey. The binary logistic regression was used to analyze the influencing factors of health management demand for abnormal values after examination.Results:There were 404 residents participating in this survey, and 182 cases were male (45.05%) and 222 cases were female (54.95%); the mean age was (39.64±15.03) years. There were 179 (44.31%) urban residents and 225 (55.69%) rural residents. There were 162 (40.10%) floating population and 242 (59.90%) non-floating population. Of the residents, 34.2% participated in the physical examination independently due to physical reasons. The age ( χ 2=16.227), household registration ( χ 2=16.117) and occupation ( χ 2=36.454) had statistically significant differences in residents′ participation in physical examination; the household registration ( χ 2=18.726, P<0.001) and occupation ( χ 2=18.094, P=0.034) had significant differences in the handling methods of abnormal values of physical examination. The age ( OR=7.00, P=0.032) and income ( OR=0.33, P=0.047) were the influencing factors of health management needs of abnormal values after health checkup. Conclusion:The awareness of active physical examination of residents in mega community is weak, and it is recommended to strengthen health education and health promotion; residents have a high willingness to the management of abnormal values after health checkup, it can be an important supplement to improve the service quality of physical examination related institutions.
ABSTRACT
Objective To investigate the levels of CD4 + CD25 + regulatory T cells and the Foxp3 in the peripheral blood of patients with ulcerative colitis ( UC), and analyze its role in the pathogenesis of UC. Methods From February 2007 to December 2008, 40 UC patients (23 active and 17 remissive), 33 irritable bowel syndrome (IBS) patients, and 32 normal controls entered our study. CD4 + CD25 + T cells were detected with flow cytometric assay. The expression of Foxp3 mRNA in peripheral blood mononuclear cell (PBMC) was detected by RTPCR. Interleukin-10 (IL-10) and transforming growth factor-β (TGF-β) in the serum from the peripheral blood of UC patients, IBS patients, and normal controls were determined with ELISA. Results There were no significant differences of the peripheral CD4 +T cell numbers among the active, remissive UC and IBS patients, and normal control groups (P=0. 126). The positive rate of CD4+ CD25+ T cells in patients with active and remissive UC were significantly lower than those in IBS patients and normal controls ( both P ＜ 0. 01 ) it was more lower in the active UC patients than the remissive UC patients ( P ＜ 0. 001 ). However, the positive rate of CD4 + CD25 + T cells showed no significant difference between IBS patients and normal control groups ( P = 0. 343 ). The percentage of CD4 + CD25 + T cells was negatively correlated with UC disease activity index ( r = - 0. 660, P ＜ 0. 001 ) and with erythrocyte sedimentation rate (r = -0. 572, P =0. 001 ). The expressions of Foxp3 mRNA in PBMC from active and remissive UC patients were significantly lower than those in both IBS patients and normal controls ( both P ＜0. 001 ). There was no significant difference of the plasma levels of IL-10 or TGF-β among the active/remissive UC patients, IBS patients, and normal controls ( all P ＞ 0. 05 ). Conclusions CD4+ CD25 + regulatory T cells remarkably decline in the active UC and show certain increase in remissive UC, indicating that these cells may be involved in the pathogenesis of UC. The decreased expression of Foxp3 mRNA may be an important factor of the aberrant developmental disorder of CD4 + CD25 + regulatory T cells.
