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.Stratification analysis was performed for different age groups(0-14,15-59,≥60 years)and different sex populations.Results Temperature had a non-linear relationship with the outpatient visits for urticaria,and there existed hysteresis.During the research period,the average daily outpatient visits for urticaria at the three hospitals in Lanzhou was 25,ranging from 1 to 76.With the rise in the daily mean temperature within 0-10 ℃,the risk of outpatient visits for urticaria first increased and then decreased.When the daily mean temperature was 2 ℃,hysteresis occurred on the 18th day,and the relative risk(

Insulin resistance refers to a pathological condition in which cells fail to respond sufficiently to insulin,leading to impaired glucose uptake and utilization. In recent years,some skin diseases have been found to be associated with metabolic syndrome,and insulin resistance is considered to be the most important pathophysiological feature of the metabolic syndrome. Recent literatures have described the role of insulin resistance in the pathogenesis of these skin diseases. This article elucidates the mechanisms of insulin resistance involved in skin diseases.
