ABSTRACT
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.

The skin mycoses, perticularly dermatophytoses, in Lanzhou district, Northwestern China, was investigated during July 2002-June 2003. The specimens from patients suspected of having dermatomycoses were examined microscopically in KOH preparations and cultured on Sabouraud dextrose agar (SDA). Among 1443 suspected cases, 594 were KOH positive and 221 cultures of fungi were isolated. The most frequently isolated fungi were Trichophyton rubrum (43.9%) Trichophyton mentagrophytes (29.4%) and Candida species (14.0%). The frequency of tinea pedis, onychomycosis and tinea manuum were 38.7, 27.8 and 13.5%, respectively. In Lanzhou district, tinea pedis is the most commonly seen dermatophytoses, and T. rubrum is the most frequent etiologic agent.
