Objective:To analyze clinical data from patients with chronic spontaneous urticaria (CSU) , and to explore their disease burden.Methods:Clinical data were retrospectively collected from CSU outpatients who visited the Tianjin Medical University General Hospital from November 2021 to October 2023. The primary evaluation indicators included the 7-day urticaria activity score (UAS7) , chronic urticaria quality of life questionnaire (CU-Q2oL) , urticaria control test (UCT) , medication use in the past 6 months, number of outpatient visits and medical expenses, CSU disease duration, and the presence of comorbid atopic diseases and autoimmune diseases. For quantitative data, results were expressed as mean ± standard deviation when normally distributed, or as median (lower quartile, upper quartile) when not normally distributed. Correlation analysis was performed using Pearson correlation coefficients, false discovery rate (FDR) correction, multivariate linear regression, and collinearity diagnostics.Results:A total of 489 CSU patients were included, comprising 303 females (62.0%) and 186 males (38.0%) , with the ages being 39.3 ± 15.0 years and disease duration being 0.75 (0.17, 3) years. The number of outpatient visits was 5.1 ± 1.9, and the medical costs were 396.4 ± 116.0 yuan. Baseline UAS7, UCT, and CU-Q2oL scores were 16.9 ± 11.0 points, 7.0 ± 3.8 points, and 51.9 ± 16.3 points, respectively. Seventy-two patients (14.7%) had a family history of atopic diseases, and 144 patients (29.4%) had comorbid atopic conditions, including atopic dermatitis ( n = 29) , allergic rhinitis ( n = 89) , allergic conjunctivitis ( n = 13) , allergic asthma ( n = 7) , and allergic sinusitis ( n = 6) . Forty-one patients (8.4%) had comorbid autoimmune diseases, including connective tissue diseases ( n = 2) and autoimmune thyroid diseases ( n = 39) . In the past 6 months, 419 patients (85.7%) received first-line or second-line therapies (antihistamines alone or in combination) , while 70 patients (14.3%) received third-line therapies, including omalizumab ( n = 35, 7.1%) , glucocorticoids ( n = 22, 4.5%) , cyclosporine ( n = 7, 1.4%) , and Tripterygium wilfordii preparations ( n = 7, 1.4%) . According to the UAS7 scores, 98 patients (20.0%) were in good control, 153 (31.3%) exhibited mild disease activity, 138 (28.2%) showed moderate activity, and 100 (20.5%) exhibited severe activity; outpatient visits and medical costs increased with disease activity (both P < 0.05) . The CU-Q2oL scores were positively correlated with the UAS7 scores ( r = 0.520, P < 0.001, FDR < 0.001) , and negatively correlated with the UCT scores ( r = -0.597, P < 0.001, FDR < 0.001) . Disease duration was positively associated with the UAS7 scores ( β = 0.223, P = 0.023) . The patients with autoimmune diseases had significantly longer disease duration ( P = 0.049) , but there was no significant difference in the UAS7 score between the patients with and without autoimmune diseases ( P = 0.340) ; there were no significant differences in disease duration or UAS7 scores between patients with and without atopic diseases (both P > 0.05) . Conclusion:Higher disease activity in CSU patients was significantly correlated with worse quality of life, increased outpatient visits, and greater economic burden.

Objective:To investigate the efficacy and safety of omalizumab in the treatment of chronic spontaneous urticaria (CSU) during pregnancy and lactation.Methods:A single-center retrospective study was conducted. From February 2022 to December 2024, 8 pregnant or lactating patients with CSU who received omalizumab treatment were collected from the Departments of Dermatovenereology and Allergy, Tianjin Medical University General Hospital, including 3 pregnant and 5 lactating patients. Clinical data were analyzed, including the patients' ages, disease duration of CSU, timing of omalizumab initiation, dosage and treatment intervals of omalizumab. During the treatment and follow-up, the 7-day urticaria activity score (UAS7) was used to evaluate disease activity of CSU patients, and adverse events were recorded.Results:The ages of the 8 patients ranged from 29 to 40 (33.25 ± 3.81) years, and the disease duration of CSU ( M[ Q1, Q3]) was 2.8 (1.6, 5.2) years. Three patients began omalizumab treatment before conception, with a dose of 300 mg every 3 - 4 weeks; after 3 - 8 sessions of treatment, pregnancy was confirmed, followed finally by successful deliveries. Five patients started omalizumab treatment at doses of 150 - 300 mg/4 weeks during lactation. All the 8 patients received omalizumab injections for 3 - 24 sessions, with an average of 10.38 sessions. Before omalizumab treatment, the UAS7 scores were 6.0 (2.8, 23.5) points; during the treatment, UAS7 scores decreased to 0 - 6 points, and CSU symptoms were completely controlled or well controlled. None of the 3 pregnant patients reported maternal adverse events, small-for-gestational-age or low-birth-weight infant outcomes, premature delivery (< 37 weeks) , spontaneous abortion (< 28 weeks) , congenital malformations in infants, or infant adverse events. One lactating patient developed a mild fever and fatigue 6 hours after the first omalizumab injection, which resolved spontaneously within 48 hours; the other 4 lactating patients did not experience any maternal or infant adverse events. Conclusion:Omalizumab may be an effective and safe treatment option for CSU patients during pregnancy and lactation.

Objective: To analyze the occurrence of unintentional injuries among college students and their association with sexual orientation and gender identity, so as to provide a targeted scientific basis for injury prevention measures and intervention strategies. Methods: From October 24 to November 18, 2023, a sample of 1 629 college students from two general universities in Beijing was selected using convenience sampling method. A questionnaire survey was conducted to collect information on the gender identity, sexual orientation and occurrence of unintentional injuries among college students in the past year. The Symptom Checklist-90 (SCL-90), Pittsburgh Sleep Quality Index (PSQI), Childhood Trauma Questionnaire (CTQ), and Delaware Bullying Victimization Scale-Student (DBVS-S) were used to assess mental health, sleep quality, childhood trauma, and dysfunctional impulsivity status. Analyses of sexual orientation and gender identity were conducted. The t-test and Chi square test were used for intergroup comparison,and multivariate Logistic regression analysis was used to examine risk factors for unintentional injuries among college students of different gender identities. Results: The incidence rate of unintentional injuries among college students was 16.94%, with boys (17.08%) being higher than girls (16.90%). Compared with those who did not experience unintentional injuries (5.28± 3.60 , 118.68±41.38), college students who experienced unintentional injuries had poorer sleep quality and mental health status ( 6.38 ±3.93, 135.59±50.96)( t =-3.92, -4.26); the differences in the incidence of unintentional injury among college students with non suicidal self injury, interpersonal violence, childhood trauma, and different sexual orientations and gender identities were all statistically significant ( χ 2=28.75, 75.18, 9.83, 16.20, 4.13) (all P <0.05). Multivariate Logistic regression analysis showed that after adjusting for age, gender and body mass index, non heterosexual orientation increased the risk of unintentional injuries ( OR=1.61, 95%CI =1.09-2.38), whereas existing non suicidal self injury behaviors ( OR=2.10, 95%CI =1.02-4.37) and poorer mental health status ( OR=1.54, 95%CI =1.05-2.27) increased the risk of unintentional injuries among non heterosexual college students (all P <0.05). Conclusions The incidence rate of unintentional injuries among college students is relatively high, with non heterosexual groups having increased risk of unintentional injuries. Mental health status and non suicidal self injury behaviors are important factors related to unintentional injuries among non heterosexual college students.

【Objective】 To examine the association between psychological behavioral problems and sleep problems in disabled children in Beijing, in order to provide reference for reducing the sleep problems of disabled children. 【Methods】 From September 2017 to February 2018, children with disabilities aged 6 to 17 years were selected by random sampling, and were investigated by a self-designed questionnaire to get their demographic characteristics.Pediatric Symptom Checklist-17 (PSC-17) was used to assess psychological and behavioral problems.The relationship between psychological behavior and sleep problems was analyzed by binary Logistic regression. 【Result】 Totally 650 children with disabilities were included in the study.The detection rates of sleep problems was significantly different in children with different genders, different school styles, different types of disabilities and different grades of disabilities (χ²=3.984, 4.437, 12.925, 18.104, P<0.001). There was statistically significant difference in the detection rate of sleep problems between children with and without psychological and behavioral problems (χ²=30.722, P<0.001).Psychological and behavioral problems were the main risk factors for sleep problems of disabled children (OR=2.540, 95%CI:1.740 - 3.709).The risk of sleep problems in day students with disabilities was 1.577 times as high as that of boarders with disabilities. 【Conclusions】 Psychological and behavioral problems of disabled children are related to sleep problems.Improving psychological and behavioral status can effectively prevent their sleep problems.

Objective:To investigate the factors influencing fall risk scores in elderly individuals.Methods:A total of 4 419 individuals were randomly selected using the cluster sampling method from Beijing, Nanning(Guangxi), and Yinchuan(Ningxia).Data on demographic characteristics and fall-related incidents were gathered and analyzed for their correlation with fall risk scores.Results:The fall risk score showed significant associations with various factors, such as the history of falls within one year( β=-3.607, 95% CI: -3.881 to -3.332), care methods( β=2.442, 95% CI: 2.226 to 2.658), exercise( β=0.714, 95% CI: 0.443 to 0.986), retirement( β=-0.585, 95% CI: -0.819 to -0.351), age( β=0.173, 95% CI: 0.159 to 0.187), and use of walking aids( β=-3.737, 95% CI: -4.054 to -3.421). Conclusions:Fall risk scores in older adults are influenced by a variety of factors.Factors such as no history of falls within the past year, living independently, engaging in physical activity, and being employed may contribute to lower fall risk scores in older adults.

Objective:To evaluate the clinical efficacy of omalizumab in the treatment of patients with chronic spontaneous urticaria accompanied by other allergic diseases.Methods:Clinical data were retrospectively collected from 74 patients, who were clinically diagnosed with chronic spontaneous urticaria and other allergic diseases, and received subcutaneous injections of omalizumab in the Department of Allergy, Tianjin Medical University General Hospital from June 2020 to September 2022. Types of allergic diseases, serum total IgE (tIgE) and allergen-specific IgE (sIgE) levels before treatment, treatment outcomes and adverse drug reactions were analyzed. Differences before and after treatment were assessed using paired t-test and Wilcoxon signed-rank sum test. Results:A total of 74 patients with chronic spontaneous urticaria were involved, including 29 with complicated allergic asthma (39.2%) , 61 with complicated allergic rhinitis (82.4%) , 6 with complicated atopic dermatitis (8.1%) , and 4 with food allergy (5.4%) . Before treatment, elevated serum tIgE or sIgE levels were observed in 44 (59.5%) patients. After the first omalizumab treatment, the urticaria control test (UCT) score significantly increased compared with that before treatment (16.00 [13.0.0, 16.00] vs. 6.00 [5.75, 9.00], Z = 7.39, P < 0.001) ; after 4 sessions of the omalizumab treatment, 82.5% (33/40) of the patients achieved complete control of urticaria symptoms or showed complete response. After omalizumab treatment, asthmatic attacks were decreased in 29 patients with allergic asthma, and asthma control test (ACT) scores significantly increased compared with those before treatment (21.07 ± 2.88 points [after the first treatment] vs. 18.48 ± 3.20 points [before treatment], t = 8.87, P < 0.001) ; among 61 patients with allergic rhinitis, global rhinitis symptom-based visual analog scale (VAS) scores (before treatment: 5.89 ± 1.29 points; after the first treatment: 3.28 ±1.46 points) and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores (before treatment: 60.10 ± 20.53 points; after the first treatment: 37.26 ± 18.83 points) both significantly decreased after the first treatment ( t = 15.04, 10.01, respectively, both P < 0.001) , and rhinitis symptoms were relieved at the same time; skin itching was relieved in 4 patients with atopic dermatitis, and allergic symptoms after contact with food allergens were also relieved in the 2 patients with food allergy after omalizumab treatment. During the treatment, only 1 patient experienced erythematous swelling, induration, and pain at the injection site. Conclusions:In the treatment of chronic spontaneous urticaria accompanied by allergic diseases, the use of omalizumab not only effectively improved urticaria symptoms, but also well controlled allergic diseases, with a good safety profile. Multiple benefits may be achieved by the use of omalizumabin in patients with chronic spontaneous urticaria accompanied by other allergic diseases.

Axenfeld-Rieger syndrome is a rare autosomal dominant hereditary disease characterized by anterior segment dysgenesis, which may be accompanied by various systemic defects, including craniofacial dysmorphism, hypodontia, microdontia, and redundant periumbilical skin.Its typical ocular manifestations include posterior embryotoxon, iris hypoplasia, peripheral anterior synechiae, corectopia and polycoria with a high prevalence of glaucoma.Patients can exhibit any combination of these features.However, family members with the same genotype may present different phenotypes due to phenotypic heterogeneity.Emerging evidence suggests that PITX2 and FOXC1 genes encoding transcription factors are primarily associated with genetic variants in ARS.Intragenic mutations and gene deletions are common types of genetic variations suspected to trigger changes in gene dosages and protein function.However, the underlying molecular mechanism remains unclear.Some patients with ARS carry mutations in the COL4A1, PRDM5, and CYP1B1 genes, but the pathogenicity of these variations has yet to be confirmed by further studies.This article provided an overview of the typical clinical features, potential correlations between phenotype and genotype, as well as gene function.

DNA damage is one of the research hotspots in the field of aging and related diseases, because it can cause cell cycle arrest and apoptosis, accelerate the body's rate of aging and increase the risk of aging-related diseases.This review will summarize the mechanisms of DNA damage in cells, animal models and individuals and its associations with aging and aging-related diseases, including cancer, cardiovascular disease, Alzheimer's disease and premature aging syndromes.We aim to provide a theoretical framework for anti-aging research and clinical intervention in the treatment of aging-related diseases.
