Objective To analyze the allergens and sex ,age distribution of chronic urticaria in Chengdu .Methods Totally 859 patients with chronic urticaria were tested with 13 kinds inhaled allergens and 15 kinds of food allergens by skin prick test .Re‐sults The top 5 allergens were:dermatophagoides farinae、dermatophagoides pteronyssinus ,cockroach ,shrimp and sea‐crab .The positive rate of dermatophagoides farinae was 58 .7% ,dermatophagoides pteronyssinus which was 55 .1% took second place .No difference was found between sex ,more inhaled allergens were found positive than food allergens in both sex groups .The positive rate was higher in people younger than 60 .Conclusion Dermatophagoides farinae ,dermatophagoides pteronyssinus ,cockroach , shrimp and sea‐crab are the commonest allergens in Chengdu .The skin prick test is important in the individualized treatment of chronic urticaria and health education .It may also be helpful in the management of chronic allergic skin diseases .

Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

Objective:To explore the effects and dose-response relationship of Tai Chi for type 2 diabetes mellitus(T2DM)and to evaluate the methodological quality of the included trials and evidence quality of the outcomes.Methods:Nine major English and Chinese databases were searched for randomized controlled trials of Tai Chi for T2DM from inception to December 2021.The effects and dose-response relationships were assessed with a meta-analysis and meta-regression using Stata.16.The methodological quality of the included studies was assessed using the risk of bias tool.The evidence quality of the outcomes was assessed using the GRADE tool.Results:A total of 24 studies with 1314 patients were included.Compared with the usual care,Tai Chi improved HbA1c(MD=-0.80％,95％Cl[-1.05,-0.54],P＜.001,I2=18.29％,very low-quality evidence),FBG(SMD=-0.58,95％Cl[-0.86,-0.31],P＜.001,I2=53.2％,low-quality evidence),fasting insulin(FIN),diastolic blood pressure,BMI,and the outcomes of quality of life(QoL)in patients with T2DM.However,when Tai Chi was compared with other exercise,there was no between-group difference in the HbA1c,FBG,TC,TG,HDL,LDL,BMI,and waist circumference(WC).Furthermore,the findings showed that an increase at every 18 weeks in length or an 823-h increase in the total time of Tai Chi intervention resulted in approximately a one unit reduction in the SMD of FBG.Conclusion:Compared with usual care,Tai Chi may improve HbA1c(with clinical significance),FBG,FIN,BMI,diastolic blood pressure,and outcomes of QoL in T2DM patients.The effects of Tai Chi were similar to those of other exercises on the HbA1c,FBG,TC,TG,HDL,LDL,BMI,and WC.Given the overall poor methodological quality and evidence quality,these findings should be treated cautiously.
