Association between meteorological factors and the incidence of acute cardiovascular disease / 中华急诊医学杂志

Objective To investigate the correlation between meteorological factors and the incidence of acute cardiovascular disease.Methods The number of calls for ambulance in case of cardiovascular disease between 2006 to 2010 was obtained from Beijing 120 emergency center and the data of meteorological factor during for the same period from Beijing Meteorological professional were collected,and then the impact of the weather factors of different seasons of weather factors on the incidence of cardiovascular disease was ere analyzed by time-stratified case-crossover design.Results The average daily incidence cases of cardiovascular disease in four seasons average daily were 5.61,4.55,5.05 and 6.03 respectively.The association between temperature Temperature and the incidence of acute cardiovascular disease was were non-linear relationship changes in spring and autumn seasons.Atmosphere Air pressure and the incidence were negatively correlated in the winter.The relative humidity of airand the incidence were related in the spring,summer,autumn.Wind and the incidence were related in the spring,summer,but negative correlation in the autumn,winter.Conclusions The incidences of acute cardiovascular disease are higher more in winter and spring than in summer and autumn.The incidences of cardiovascular disease are related with temperature,relative humidity,wind speed and other meteorological factors.,The influence of meteorological factors on the incidence of the disease delays to occur after changes in weather.

TAF to The Hypoimmunity Mice on Effect of T Cell Polarization / 浙江中医药大学学报

[Objective]To study the effect of T cell groups of CD4+,CD8+,CD4+/CD8+,IL-4,IFN-? in the hypoimmunitymice induced by hydrocortisone to discuss its function of regulating the immune function and CD4+TH cell’s inferior change of group,have offered the experiment basis for clinical practice of TAF.[Method] FACS measured the T lymphocyte phenotype;the level of cytokine IFN-r and IL-4 was detected by ELISA.[Result] TAF can raise CD4+T lymphocyte of hypoimmunitymice,suppress CD8+ T lymphocyte expression,raise CD4+/CD8+ ratio;And can make the level of serum IFN-r obviously enhanced in hypoimmunitymice,and the level of IL-4 was very low.[Conclusion] TAF can rebuild immune function of hypoimmunitymice,promote organism Th0 to split up to Th1,maintain the advantage state of TH1,and strengthen the function of cellular mediated immunoresponse.
