Objective:To investigate the current status of occupational stress among electronic manufacturing workers in Qingdao and analyze its effect on depressive symptoms and anxiety symptoms.Methods:From July to September 2022, a cluster random sampling method was employed to select frontline workers from 14 electronic manufacturing enterprises in Qingdao as the study subjects. A total of 1134 questionnaires were distributed, with 1000 valid questionnaires collected, yielding an effective response rate of 88.18%. The Core Occupational Stress Scale (COSS), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) were adopted to assess occupational stress, depressive symptoms, and anxiety symptoms, respectively. Binary logistic regression was employed to analyze influencing factors of occupational stress and its effects on depressive and anxiety symptoms.Results:The detection rates of occupational stress, depressive symptoms, and anxiety symptoms were 15.1% (15/1000), 7.9% (79/1000), and 13.8% (138/1000), respectively. The influencing factor analysis of occupational stress revealed that female gender ( OR=0.621, 95% CI: 0.434-0.890) and weekly working hours of 45-48 hours ( OR=0.537, 95% CI: 0.309-0.935) were protective factors ( P<0.05), while weekly working hours ≥55 hours ( OR=2.176, 95% CI: 1.290-3.670) and shift work ( OR=2.038, 95% CI: 1.412-2.940) were risk factors ( P<0.05). Spearman correlation analysis showed that the COSS score was positively related with the PHQ-9 score and the GAD-7 score ( rs=0.438, 0.289, P<0.01). Workers judged with occupational stress had 3.596 times (95% CI: 2.181-5.931, P<0.001) and 3.121 times (95% CI: 2.046-4.761, P<0.001) higher risks of detecting depressive and anxiety symptoms compared to those without occupational stress. Conclusion:Electronic manufacturing workers in Qingdao experience a certain level of occupational stress, which may increase the risk of developing depressive and anxiety symptoms. Enterprises should implement appropriate interventions to promote workers' mental health.

Objective:To evaluate the clinical efficacy and safety of an antioxidant gel containing tea polyphenols combined with narrow-band ultraviolet B in the treatment of vitiligo.Methods:A single-center, randomized controlled clinical trial was conducted. From April 25 to June 27, 2024, patients with vitiligo were selected from the Department of Dermatology, Hangzhou Third People's Hospital. An open-label and researcher-blinded design was used. The patients were divided into 3 groups: a phototherapy group receiving phototherapy alone, a tea polyphenols combined group treated with an antioxidant gel containing tea polyphenols combined with phototherapy, and a positive control group treated with an antioxidant gel containing superoxide dismutase combined with phototherapy, with the treatment duration being 3 months. The efficacy was evaluated using the Vitiligo Area Scoring Index (VASI), and when the VASI was improved by ≥ 10%, the treatment would be considered effective. Changes in skin aging and skin barrier function indicators before and after treatment were assessed for 72 vitiligo lesions in the tea polyphenols combined group and for 72 lesions in the phototherapy group. Comparisons between the groups were performed using one-way analysis of variance, Fisher's exact test, chi-square test, or t test. Results:A total of 171 vitiligo patients with 307 target lesions were successfully followed up in this study, including 74 males and 97 females, and their ages ranged from 1 to 64 years. Among the 307 lesions, 95 were treated with phototherapy alone, of which 35 showed improvement, resulting in a total response rate of 36.8% and an average VASI improvement rate of 10.9%; adverse reactions occurred in 29 lesions (30.5%). Of 138 lesions treated with the antioxidant gel containing tea polyphenols combined with phototherapy, 73 showed improvement, resulting in a total response rate of 52.9% and an average VASI improvement rate of 24.0%; adverse reactions occurred in 10 lesions (7.2%). In the positive control group, 74 lesions were treated, and 40 showed improvement, resulting in a total response rate of 54.1% and an average VASI improvement rate of 18.3%; adverse reactions occurred in 5 lesions (6.8%). Compared with the phototherapy group, the tea polyphenols combined group showed a significantly increased total response rate and a VASI improvement rate (both P < 0.01), but a significantly decreased incidence rate of adverse reactions ( P < 0.001). No significant differences in the above indicators were observed between the tea polyphenols combined group and the positive control group (all P > 0.05). In addition, the changes in skin barrier function and skin aging indicators (except for wrinkle depth) before and after treatment were significantly reduced in the tea polyphenols combined group compared to the phototherapy group (all P < 0.05). After the phototherapy alone, the transepidermal water loss significantly increased ( P = 0.004), and the water content of the stratum corneum significantly decreased ( P = 0.012). However, no significant differences in skin barrier function or skin aging indicators were found between pre- and post-treatment in the tea polyphenols combined group ( P > 0.05) . Conclusion:The antioxidant gel containing tea polyphenols could effectively improve the efficacy of narrow-band ultraviolet B in the treatment of vitiligo, and alleviate skin aging and barrier damage caused by phototherapy.

Objective:Based on the adverse drug event active surveillance and assessment system-Ⅱ (ADE-ASAS-Ⅱ) and the information of inpatients in the hospital information system (HIS), the automatic monitoring module of movement disorders was constructed and its application effect in the real-world study of drug-induced movement disorders (DIMDs) was explored.Methods:Literature reviews, case reports, spontaneous reports and medical records were collected, the keyword set was screened based on ADE-ASAS-Ⅱ system and text classification technology, and an automatic monitoring module was constructed.

Objective The data related to adverse drug reaction of trastuzumab deruxtecan(T-DXd)were mined to provide references for its clinical management and adverse event handling.Methods Based on the Food and Drug Administration Adverse Event Reporting System(FAERS)database,the data reported from the post-marketing period of T-DXd until the fourth quarter of 2024 were extracted.The proportion imbalance method,specifically the reporting odds ratio(ROR)method,was used to mine and analyze the data related to adverse events of T-DXd.Results A total of 13 134 cases of adverse events related to T-DXd were obtained from the FAERS database.Gastrointestinal disorders were the most common,with 2348 adverse reaction signals,accounting for 17.88％.The most frequent adverse reactions were nausea(n=809),interstitial lung disease(n=732),and fatigue(n=579).The one with the highest ROR value was Listeriosis gastroenteritis(ROR=1228.74).The highest number of deaths were from interstitial lung disease(226),pneumonitis(90),and nausea(67).Conclusion By mining data on real-world adverse drug reaction related to T-DXd,suggests that pulmonary function,cardiac function,complete blood count and other parameters should be closely monitored during treatment for early diagnosis and treatment of corresponding complications.

Objective To explore the diagnostic value of ultrasonography in ischiofemoral impinge-ment syndrome(IFI).Methods Fifty-six patients who underwent hip MRI with confirmed IFI diagnosis and completed ultrasonography examinations were enrolled as the IFI group,including 44 females and 12 males.Twenty healthy volunteers were concurrently recruited as the control group,consisting of 10 females and 10 males.The control group underwent ultrasonography examinations of bilateral hip joints,whiletheischialfemoralspace(IFS)andquadratusfemoristhickness(QFT)of both groups were measured and recorded.Then measurements were compared within(by laterality and gender)and between the two groups using independent-samples t-tests.Moreover,receiver operating characteristic adults,males exhibited significantly higher IFS and QFT values than females(P<0.05).Within the IFI group,males with affected hips had significantly higher IFS than females(P<0.05),while no sig-nificant differences were observed in QFT between different genders(P>0.05).Moreover,affected hips in the IFI group showed significantly narrower IFS and thicker QFT compared to both contralateral hips and the control group(P<0.001).In addition,the diagnostic cut-off values of IFS and QFT for ultrasound diagnosis of IFI were 22.93 mm and 16.48 mm,respectively.At these thresholds,the ar-eas under the curve(AUC)were 0.997 and 0.977,with sensitivities of 97.8%and 91.8%,and speci-ficities of 98.4%and 97.8%,respectively.Conclusion Ultrasound can serve as a reliable diagnostic technique for IFI,where narrowing of the IFS and thickening of the QFT should raise suspicion of this condition.
