ObjectiveTo investigate the relationship between the non-fasting triglyceride and glucose （TyG） index and hyperglycemia in pregnancy during the third trimester in high altitudes. MethodsThis study selected clinical and laboratory data of 774 Tibetan singleton pregnant women who delivered at Chaya People's Hospital of Qamdo city in Xizang autonomous region， from January 2023 to April 2025. The non-fasting TyG index was calculated from non-fasting triglyceride （TG） and random plasma glucose （PG）. Based on the tertiles of the non-fasting TyG index values， the individuals were split into three groups （corresponding to non-fasting TyG index of 8.89 and 9.21， respectively）. The baseline clinical characteristics， lipid levels and the occurrence of developing hyperglycemia in pregnancy were compared among the three groups. Statistical analyses were performed using ANOVA， Kruskal-Wallis H test， Chi-square test， or Fisher exact test and the relationship between the non-fasting TyG index and hyperglycemia in pregnancy were examined using multivariate logistic regression models and curve fitting. ResultsA total of 774 Tibetan singleton pregnant women were included， with a average age of 27.3 ± 6.1 years， a pre-delivery body mass index （Pre-BMI） of （25.2±2.3）kg/m² ， a proportion of 26.7% （207/774） primigravid women， the mean non-fasting TyG index was 9.1 ± 0.4。Thirty pregnant women were diagnosed with hyperglycemia in pregnancy， with a detection rate of 3.9% （30/774）. Statistically significant differences in serum total cholesterol （TC）， TG， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） levels were identified when comparing different non-fasting TyG groups （all P values <0.05）. Subsequent trend test analysis indicated that the levels of TC， TG， LDL-C， and PG gradually increased with elevated the non-fasting TyG index （ F_{trend TC}=95.61， P<0.001； F_{trend TG}=1 051.91， P<0.001； F_{trend LDL-C} = 97.20， P < 0.001； F_{trend TG}=195.20； P<0.001）. After adjustment for maternal age， pre-delivery BMI， altitude， TC， LDL-C， and HDL-C， multivariate Logistic regression models revealed independent positive associations between non-fasting TyG index and hyperglycemia in pregnancy （Model 1： OR=2.72， 95% CI： 1.13-6.53， P=0.026； Model 2： OR=2.56， 95% CI： 1.01-6.50， P=0.048； Model 3： OR=2.72， 95% CI： 1.06-6.97， P=0.037； Model 4： OR=4.02， 95% CI： 1.42-11.40， P=0.009） and the incident of hyperglycemia in pregnancy showed an increasing tendency as increasing with the non-fasting TyG index， however， this association did not statistical significance （P _trend >0.05）. Curve fitting by restricted cubic splines （RCS） were used to assess linearity between non-fasting TyG and hyperglycemia in pregnancy， and there was a linear dose-response relationship between non-fasting TyG and hyperglycemia in pregnancy （P _{for non-linear} = 0.515）. ConclusionNon-fasting TyG index in the third trimester is a risk factor for hyperglycemia in pregnancy among the Tibetan singleton pregnant women at high altitudes and there was a possible linear dose-response relationship between the non-fasting TyG index and hyperglycemia in pregnancy.

ObjectiveTo explore the distribution patterns and correlations of pet-related cat/dog dander allergens and mold allergens in patients with allergic diseases， providing evidence for individualized diagnosis， treatment， and prevention strategies. MethodsA retrospective analysis was conducted on 798 patients diagnosed with allergic diseases at the Third Affiliated Hospital of Sun Yat-sen University between April 2021 and October 2023. All patients underwent UniCAP platform testing for specific immunoglobulin E （sIgE） levels against cat dander， dog dander， and mold mix （mx1/mx2）， alongside total IgE （tIgE） quantification. Descriptive statistics， Mann-Whitney U tests， and chi-square analyses were employed to evaluate allergen distribution and interrelationships. ResultsAmong the 798 patients （395 males， 403 females， ratio 1∶1.02）， their ages ranged from 0.67 to 69 years （median 14 years， IQR 6-29）. A total of 63.2% （504/798） had a single allergic disease， with allergic rhinitis （AR， 49.2%） being the most common. The remaining 36.8% （294/798） had ≥2 allergic diseases， with AR combined with atopic dermatitis （AD， 10.7%） as the predominant comorbidity. The positivity rate for cat/dog dander sIgE was 24.1% （192/798）， with a significantly higher prevalence in females （30.8%） than males （16.7%， P＜0.05）. Cat dander sensitization increased with age in patients under 18 years. Among positive cases， cat dander sIgE level 2 was most frequent （25.9%）， while dog dander sIgE level 1 predominated （55%）. Patients with cat dander sIgE levels 4-6 had significantly higher tIgE than those with levels 1-3 （P＜0.05）. The positivity rate for mold mix （mx1/mx2） sIgE was 7.4% （59/798）， with mx2 as the primary sensitizer and level 2 being the most common. In mx2-positive patients， the cat/dog dander sIgE positivity rate （44.8%） was significantly higher than that in mx2-negative patients （17.9%， P＜0.05）， and tIgE levels were also higher （P＜0.05）. ConclusionCat dander sensitization increases with age in children. Cat/dog dander and mold allergens are closely linked to AR and AR combined with AD. Synergistic correlations exist between cat/dog dander sIgE and mold mx2 sIgE. Combined detection of these allergens is critical for precision diagnosis and management of pet-related allergic diseases.

Objective To investigate the epidemiological characteristics of common respiratory viruses and atypical pathogens in late-term neonates during the pandemic period of Coronavirus Dis-ease 2019(COVID-19)and the impact of non-pharmaceutical interventions(NPIs)on neonatal re-spiratory pathogens.Methods A total of 2,452 late-term hospitalized neonates caused by respirato-ry infection symptoms at the Children's Hospital of Soochow University from January 2018 to February 2023 were included in the study.Data from January 2018 to December 2019 were used as pre-pan-demic control group,and data from January 2020 to December 2021 were used as post-pandemic con-trol group.The changes in nucleic acid test results for eight common pathogens in hospitalized chil-dren during the pandemic period of COVID-19 were retrospectively analyzed.Data from March 2020 to February 2023 were compared to summarize the epidemiological characteristics of neonatal respira-tory pathogens in different seasons after the normalization of the pandemic period of COVID-19.Results Among the 2,452 hospitalized neonates,364(14.85％)tested positive for pathogens,with respiratory syncytial virus(RSV)having the highest detection rate of 262 cases(10.69％),followed by parainfluenza viruses(PIVS)with 64 cases(2.61％).The total number of positive cases for the eight pathogens before and after the pandemic control measures were 229(17.1％)and 96(12.3％)respectively.The detection rate after the pandemic control measures was significantly lower than be-fore(P＜0.05).The detection rates of all eight pathogens decreased after the pandemic control measures,but only the difference in the RSV detection rate was statistically significant(P＜0.05).The peak month for RSV-positive cases was delayed by one month after the pandemic control measures compared to pandemic control before,and there were two peaks in RSV incidence in 2022.PIVS was more prevalent in spring,summer,and autumn before the pandemic control measures,but became more prevalent in winter afterward,with a higher peak in positive cases detected after the control measures than pandemic control before;the seasonality of PIVS infection changed.Conclusion After the implementation of pandemic control measures for COVID-19,the detection rate and epidemiology of common respiratory pathogens in late-term neonates with respiratory infections in Suzhou have changed.NPIs such as wearing masks,hand hygiene,maintaining social distance,and avoiding un-necessary outings have a certain preventive effect on the outbreak of respiratory pathogens.

BackgroundThe prevalence of depressive disorder in adolescents is on the rise. There have been studies on the pairwise relations between dysfunctional attitude， negative automatic thoughts， positive coping style and depressive symptoms in the past. However， the impact of the intrinsic relations among dysfunctional attitude， negative automatic thoughts and positive coping style on depressive symptoms is still unclear. ObjectiveTo explore the influence of dysfunctional attitude on adolescent depressive symptoms and examine the action path of negative automatic thoughts and positive coping style on it， in order to provide references for intervention for adolescent patients with depressisve disorder. MethodsThis study involved 162 adolescent patients with depressive disorder， who met the diagnostic criteria for depressive episodes in the International Classification of Diseases， 10th edition （ICD-10） and received treatment in Taiyuan Psychiatric Hospital from October 1， 2022 to October 31， 2023. These patients were evaluated using Self-rating Depression Scale （SDS）， Dysfunction Attitude Scale （DAS）， Positive Coping Style Subscale in Simplified Coping Style Questionnaire（SCSQ） and Automatic Thoughts Questionnaire （ATQ）. Pearson correlation analysis was adopted to examine the correlation among scores of scales above. Model 6 in Process 3.4.1 was adopted to test the acting path of negative automatic thoughts and positive coping style between dysfunctional attitude and adolescent depression symptoms. ResultsA total of 148 adolescent patients with depressive disorder completed an effective questionnaire survey， with a response rate of 91.36%. The direct effect value of dysfunctional attitude on depressive symptoms was 0.423 and the effect size was 63.32%. Negative automatic thoughts and positive coping style affected as acting path between dysfunctional attitude and depressive symptoms， with effect values of 0.156 （accounting for 23.35% of the total effect） and 0.045 （accounting for 6.74% of the total effect） respectively. Meanwhile， negative automatic thoughts and positive coping style affected as a chain reaction pathway between dysfunctional attitude and depressive symptoms， with an effect value of 0.044， accounting for 6.59% of the total effect. ConclusionDysfunctional attitude can not only directly affect the depressive symptoms of adolescent patients with depressive disorder， but also affect the depressive symptoms of adolescent patients with depressive disorder through the independent path or chain path of negative automatic thoughts and positive coping style.

“Deficiency cause， cold accumulation， and qi stagnation” originates from Essentials from the Golden Cabinet （《金匮要略》）， which is a guiding principle for the pathogenesis of women's diseases， pioneering the differentiation and treatment of women's diseases based on patterns， and having a profound influence on future generations. Following the classical principles and simplifying the complexities， this paper explored the pathogenesis and mechanism of polycystic ovary syndrome （PCOS） from the perspective of “deficiency cause， cold accumulation， and qi stagnation”， and believed that depletion of essence and blood， long-term accumulation of internal cold， and qi constraint and blood stasis are the causes of PCOS， with depletion of essence and blood， and lack of nourishment of zang-fu （脏腑） organs as the root， and cold pathogen invasion， qi constraint and blood stasis as the branch. The main treatment principle is “treating deficiency with supplementation”， and dispelling pathogen while reinforcing healthy qi， along with “treatment of cold by warming” and “treatment of stagnation by dispersing”. This is of great significance for the treatment of polycystic ovary syndrome. Clinically， these methods can be used flexibly to guide treatment and formula selection for PCOS， with the goal of harmonizing qi and blood and regulating menstruation.
