Objective To evaluate the influence of temperature on the outpatient visits for urticaria in Lanzhou City and its hysteresis and to find out the sensitive populations by sex and age stratification.Methods We collected the urticaria outpatient data in three grade A class three hospitals as well as the meteorological data and air pollutant data in Lanzhou from January 2011 to December 2017.The distributed lag non-linear model(DLNM)was employed to analyze the influence of daily mean temperature on the outpatient visits for urticaria.

Objective To quantitatively evaluate the associations of PM,PM,NO,and SO concentrations with the outpatient visits for atopic dermatitis in Lanzhou. Methods The data of outpatient visits,together with meteorological data and air pollutant data,from January 2013 to December 2017 were collected.The generalized additive model based on Poisson distribution was employed to study the lag effects of PM,PM,NO,and SO concentrations on the visits of outpatients,with the seasonal and long-term trends and day-of-the-week effect controlled.

Objective To determine the relationship between air pollutants [SO,NO,8 hours average concentration of ozone(O8h)] and outpatient visits for acne in Lanzhou,China. Methods Data of daily outpatient visits for acne and concentrations of air pollutants(SO,NO,and O8h)from January 2013 to December 2017 were collected.With the control of long-term trend and day-of-week effect,a distributed lag nonlinear model was used to analyze the lag and cumulative effects of air pollutants on the outpatient visits.

Burkitt lymphoma (BL) is a highly aggressive neoplasm, which arising from the germinal center or post germinal center B-cell. Primary breast lymphomas are extremely rare, and the most common histologic type is diffuse large B-cell lymphoma. Primary BL of the breast is much less common than the other types of lymphoma.

ZnS:Er quantum dots were prepared in aqueous medium from readily available precursors. The construction, morphology and luminescence properties of the ZnS:Er quantum dots were evaluated by X-ray diffraction (XRD), transmission electron microscopy (TEM), and photoluminescence spectra. The average particle size was calculated using the Scherrer formula to be 4 nm, which is also observed from high resolution transmission electron microscopy (HRTEM) image.
