Objective To analyze the factors influencing the occupational health literacy (OHL) level among workers in key industries from the perspectives of both individual workers and enterprises. Methods A total of 32 336 front-line workers from 12 key industries in the secondary industry in Guangdong Province were selected as the research subjects by a stratified cluster random sampling method. Their OHL level was investigated using Occupational Health Literacy Questionnaire of National Key Populations, and the influencing factors were analyzed. Results The OHL level of the research subjects was 48.5%. The OHL level of the research subjects in four dimensions from high to low was basic knowledge of occupational health protection, occupational health practice and behavior, legal knowledge of occupational health, and basic skills of occupational health protection (80.7%, 61.2%, 48.3% and 29.5%, respectively). The multivariable logistic regression analysis showed that the OHL level of female workers was lower than that of males (P<0.05). Lower OHL was also associated with older age, lower education level, lower personal monthly income of workers (all P<0.01). The workers with length of service < 3 years and ≥ 20 years had lower OHL level than those with length of service 3-<10 years and 10-<20 years, respectively (all P<0.05). Workers in larger enterprises had higher OHL levels (all P<0.01). The OHL level of workers in the sixth category of industries with occupational injuries had higher occupational injury risks than those in the third and fourth categories (all P<0.05). The OHL levels of workers in state-owned enterprises, private enterprises, foreign-funded enterprises, and other enterprises were higher than that of workers in public institutions (all P<0.05). Conclusion The influencing factors of workers′ OHL in key industries of the secondary industry include individual factors (gender, age, education level, personal monthly income, length of service) and enterprise factors (enterprise size, enterprise nature and industry injury risk category). Female, older workers, those with lower education or income, and those with short length of service represent priority groups for OHL interventions, while small and micro enterprises are priority units for future workplace health promotion intervention.

Objective:To understand the current antiviral treatment status and various clinical types of treatment plans in Xiamen City so as to explore ways to improve and optimize the diagnosis and treatment standards for chronic hepatitis B.Methods:A cross-sectional survey method was used to study the antiviral treatment status and treatment plans for chronic hepatitis B patients who visited and were diagnosed in the Department of Infectious Diseases and Hepatology of all tertiary hospitals in Xiamen City at 0:00~23:59 on May 25, 2022.Results:A total of 665 cases were surveyed in this study, with an antiviral treatment rate of 81.2%(540/665). The antiviral treatment rate of patients who accorded with the current guidelines for antiviral treatment indications was 85.8%(507/591). The antiviral treatment rate for 362 outpatients was 72.9%(264/362). Among them, the antiviral treatment rates were 80.1%, 89.3%, and 25.0%(226/282, 25/28, 13/52), respectively, for patients diagnosed with chronic hepatitis B, hepatitis B cirrhosis, and hepatitis B surface antigen-carrying status. The treatment plan for all outpatient patients was mainly oral nucleos(t)ide analogues, accounting for 59.1%(214/362). The antiviral treatment rate for 303 inpatients was 91.1%(276/303). The various clinical types of antiviral therapy rates among all patients were 70%~95%. The antiviral treatment plan for inpatients was mainly based on pegylated interferon alpha treatment, accounting for 72.6%(220/303).Conclusion:Antiviral treatment for chronic hepatitis B in Xiamen City can still be strengthened to meet the current demand for expanding antiviral treatment indications. Antiviral treatment rates and various types of treatment plans differ between outpatients and inpatients; thus, further awareness and acceptance of the goal of improving antiviral therapy, especially in outpatients, and the possibility for a clinical cure based on pegylated interferon alpha treatment are needed to maximize the benefit to more patients.

ObjectiveTo explore the effect of occupational stress on work-related musculoskeletal disorders (WMSDs) in electronics manufacturing workers. Methods A total of 392 front-line workers in two electronic manufacturing enterprises in Guangdong Province were selected as the research subjects using the judgment sampling method. The prevalence of WMSDs and the level of occupational stress of the research subjects were investigated using the Musculoskeletal Disorders Questionnaire and the Core Occupational Stress Scale. Results The total WMSDs detection rate was 39.5%, and the multi-site WMSDs detection rate was 30.6%. The detection rate of occupational stress was 14.8%. The total WMSDs detection rate and multi-site WMSDs detection rate in the occupational stress group were higher than those in the non-occupational stress group (65.5% vs 35.0%, 56.9% vs 26.0%, both P<0.01). Binary logistic regression analysis result showed that the risk of WMSDs in the occupational stress group was higher than that in the non-occupational stress group after adjusting the effect of confounding factors such as age, gender, job type and work days per week (P<0.01). Conclusion The occupational stress may increase the risk of WMSDs in electronics manufacturing workers. Reducing the level of occupational stress among workers in electronic manufacturing enterprises is beneficial for reducing the risk of WMSDs.

Objective:To study the clinical characteristics and imaging features of neonatal ovarian cysts and to analyze treatment and prognosis of ovarian torsion.Methods:From January 2011 to December 2021,neonates with ovarian cysts admitted to the department of neonatology and pediatric surgery of our hospital were retrospectively studied. They were assigned into ovarian torsion group and non-torsion group. Their clinical manifestations, imaging features, pathological results, treatment and prognosis were reviewed and compared.Results:A total of 44 neonates with ovarian cysts were included, all without specific clinical manifestations. 10 neonates were treated with conservative therapy and 34 received surgery. Ovarian torsion were confirmed during surgery in 23 patients. All 34 patients received abdominal ultrasound preoperatively and 31 (91.2%, 31/34) were diagnosed with ovarian cysts. The accuracy rates of ultrasound for cyst location and ovarian torsion were 85.3% (29/34) and 82.6% (19/23),respectively. 30 patients received abdominal CT scan and 23 (76.7%, 23/30) were diagnosed with ovarian cysts. The accuracy rates of CT scan for cyst location and ovarian torsion were 53.3% (16/30) and 47.8% (11/23), respectively. Among the 34 patients treated with surgery, ovarian cyst dissection was performed in 11 patients and cyst resection in 23 patients with torsion necrosis. 24 patients had simple cysts including 15 torsion necrosis (62.5%, 15/24) and 10 had complicated cysts including 8 torsion necrosis(80.0%, 8/10). The average diameter of ovarian cysts was significantly larger in the torsion group [(8.4±1.6) cm] than the non-torsion group [(4.7±1.2) cm] ( P<0.05). Conclusions:Neonatal ovarian cysts are mostly unilateral without specific clinical manifestations. Large, bilateral and complex cysts are prone to torsion necrosis. Abdomen ultrasound has advantages than CT scan for the localization of the ovarian cyst and diagnosis of ovarian torsion. Surgical treatment is necessary after diagnosis.

{L-End}Objective To establish the norm of Core Occupational Stress Scale (COSS) for electronic manufacturing industry workers in China. {L-End}Methods A total of 3 049 workers from five electronic manufacturing enterprises in four prefecture-level cities concentrated distribution of the electronics manufacturing industry in China were selected as research subjects using a stratified sampling method. COSS was used to investigate occupational stress levels, and the mean norm, percentile norm and threshold norms were established. {L-End}Results The average score of COSS for the electronic manufacturing industry workers in China was (43.5±7.4) points, and the average scores of social support, organization and reward, demand and effort, and autonomy dimensions were (9.5±3.1), (15.1±3.9), (13.1±3.0), and (5.7±2.0) points, respectively. A total score of 0.0-<47.0 points was determined as no occupational stress, 47.0-<51.0 points as mild occupational stress, 51.0-≤54.0 points as moderate occupational stress, and >54.0 points as severe occupational stress. {L-End}Conclusion The norm of COSS for workers in China's electronics manufacturing industry has been established, which can provide a reference for the evaluation and intervention of their occupational stress levels.

Objective:To report the clinical manifestation and genetic characteristics of a case of de novo Huntington′s disease due to paternal intermediate alleles. Methods:Clinical data and imaging features of a middle-aged female, who complained of unstable walking without positive family history and was admitted to Xuanwu Hospital, Capital Medical University on September 20, 2022, were retrospectively analyzed. The serum samples of the patient and her parents were used to screen HTT gene dynamic mutation in accordance with the principle of informed consent and voluntary. And the relevant literatures were reviewed. Results:This is a 38-year-old female with progressive course, who presented as ataxia, involuntary movement at the end of extremities, dystonia, and cognitive impairment. Imaging results showed atrophy of bilateral caudate nuclei, as well as decreased glucose metabolism of bilateral caudate nuclei, putamen and partial cortex. Genetic testing showed the abnormal expansion of polymorphic trinucleotide (CAG) repeats in HTT gene and confirmed the diagnosis of Huntington′s disease. The CAG repeat length of the patient was 17/47 (pathopoiesis), of the father was 17/35 (intermediate alleles), and of the mother was 17/17 (normal). Conclusions:Paternal intermediate alleles may cause the first case of Huntington′s disease in a family. Importantly, HTT gene screening should be performed for the patient and parents when the diagnosis of Huntington′s disease is clinically possible despite negative family history, to prevent the misdiagnosis.

Objective To explore the effects and influencing factors of traditional occupational health training on occupational health literacy (OHL) of employees in micro-, small- and medium-sized enterprises. Methods A total of 540 employees from 154 micro-, small- and medium-sized enterprises, who participated (347 employees) and not-participated (193 employees) in traditional occupational health training, and 171 community residents/students (not-participated in occupational health training) were selected as the research subjects using the convenient sampling method. The OHL level was investigated using Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level of employees was 43.3% (234/540). Among them, the overall OHL level of untrained and trained employees was 38.9% and 45.8%, respectively, and the overall OHL level of community residents/students was 43.3%. The results of multivariate logistic regression analysis showed that the higher the educational level, the higher the OHL level (all P<0.01). The OHL level of untrained and trained employees was higher than that of untrained community residents/students (all P<0.05). The interaction of education level and training status had no statistical difference on the OHL level of the research subjects (P>0.05). The results of factorial design analysis of variance showed that the overall OHL score rate of untrained employees and trained employees was higher than that of untrained community residents/students (all P<0.05). However, there was no significant difference in overall OHL score rate between untrained and trained employees (P>0.05). Conclusion The role of traditional occupational health training in improving the OHL level of employees in micro-, small- and medium-sized enterprises needs to be improved. The responsibility of enterprise occupational health training should be implemented, and multiple measures should be taken to enrich the ways and approaches of occupational health education for enterprise employees, to effectively improve the OHL of workers.
