OBJECTIVEIn order to observe the therapeutic efficacy of food control to recurrent oral ulcer (ROU), alimentary control of certain foods was employed to relieve outbreak of ROU.

METHODSThe kits for food intolerant IgG of certain food were used to test the intolerant food of fifty patients with ROU. Observations and assessments for alimentary control were made after three months' treatment on these patients.

RESULTSThe top three of intolerant foods were crab, egg and milk and the remission rate of ROU reached 74% after treatment.

CONCLUSIONThe result of food intolerant IgG testing has certain function to alimentary control therapy for remitting the outbreak of ROU.

Objective To explore the association between the characteristics of the genetic polymorphism of human leukocyte antigen (HLA)-B and HLA-DR alleles and asthma in Guangxi Zhuang and Han nationality children.Methods Eighty-four blood-unrelated asthmatic individuals,57 cases of Han nationality and 27 cases of Zhuang children with asthma,and 168 healthy controls,included 83 cases of Han nationality and 85 cases of Zhuang people without asthma and atopy living in Nanning region of Guangxi were involved in the study.All asthmatic patients′serum total IgE levels were measured with UniCAP Pharmacia system,and skin-prick test with ten kinds of inhalant allergens were taken and pulmonary functions were measured among the patients.HLA oligonucleotide array was used to 40 gene alleles of HLA-B and 26 HLA-DR.Comparison of the frequency distribution of HLA-DR alleles and HLA-B alleles in 2 groups was evaluated by chi-square test,and the risk for asthma of the HLA allele′s carriers was valuated by OR value.Results Twenty-seven alleles at HLA-B locus and 21 alleles at HLA-DR were detected.The distribution of HLA-B46,HLA-DRB1070X and HLA-DRB111XX alleles only in Han people was distinctive in the asthmatic patients compared with those in healthy controls(Pa

This study analyzed the epidemic characteristics and spatial and temporal clustering of leptospirosis in Wenzhou from 2014 to 2023,to provide a scientific basis for prevention and control.Data for leptospirosis cases reported in Wenzhou from 2014 to 2023 were collected.Descriptive epidemiological approaches were used to analyze the cases'prevalence character-istics.Spatial autocorrelation analysis was performed in ArcGIS 10.2 software,and spatiotemporal clusters were scanned with SaTScan 10.1 software.From 2014 to 2023,189 leptospirosis cases were reported in Wenzhou,and the average annual inci-dence rate was 0.23/100 000.Relatively fewer cases occurred in 2014-2018,whereas significantly more cases occurred after 2019,and the largest number of reported cases was reported in 2021(62 cases).The peak incidence was from August to Octo-ber,accounting for 88.36％of the total incidence.The cases were mainly in males,and the sex ratio was 5.30∶1 male:female.Moreover,the cases were mainly in people in their 60s,accounting for 59.26％of total cases,and in people who were farmers,accounting for 72.49％of total cases.Global spatial autocorrelation analysis indicated that cases were randomly distributed from 2014 to 2018,and the incidence showed spatial clustering from 2019 to 2023(Moran's I＞0,P＜0.05).Local spatial autocor-relation and spatiotemporal scanning analysis revealed that leptospirosis cases were concentrated primarily in northern hilly areas of Yongjia County and other inland areas rich in vegetation from 2019 to 2023.In the past 5 years,the number of lepto-spirosis cases in Wenzhou increased,and the incidence of leptospirosis showed clear seasonal and spatial clustering.Cases were mainly in middle-aged and older farmers.Recommendations in-clude expanding the monitoring scope of leptospirosis,and per-forming prevention and control measures such as health education for key groups in key areas before the high-incidence season.
