Background The association between occupational physical activity (OPA) and cardiometabolic risk factors remains controversial, potentially due to differences in the associations between OPA and various cardiometabolic indicators, as well as the lack of a clearly defined optimal OPA range for multiple-indicator synergistic benefits. Objective To investigate the relationship between OPA and cardiometabolic risk factors in individuals at high risk of cardiovascular disease (CVD) in Hubei Province, and to explore an optimal OPA range for multi-indicator improvements. Methods Data were derived from the Hubei Province dataset of the China Health Evaluation And Risk Reduction Through Nationwide Teamwork from 2015 to 2023, including 19028 high-risk CVD individuals. OPA (metabolic equivalent·h·d⁻¹, MET·h·d⁻¹) was assessed using the China Kadoorie Biobank physical activity questionnaire, anthropometric measurements (height, weight, waist circumference) and cardiometabolic indicators (blood pressure, fasting blood glucose, lipid profiles) were measured. Multivariate logistic regression was used to analyze the association between logOPA quartiles (Q1-Q4) and abnormal cardiometabolic indicators, while restricted cubic spline (RCS) models were employed to explore their dose-response relationships. Subgroup and interaction analyses were also conducted by gender. Results The median OPA of all participants was 12.86 MET·h·d⁻¹ (male: 14.40 MET·h·d⁻¹, female: 11.14 MET·h·d⁻¹). After adjusting for confounders, compared with the Q1 group, logOPA in the Q4 group was associated with 20% (OR=0.80, 95%CI: 0.72, 0.89), 14% (OR=0.86, 95%CI: 0.78, 0.96), and 13% (OR=0.87, 95%CI: 0.79, 0.95) reduction in the risk of abdominal obesity, low high-density lipoprotein cholesterol (HDL-C), and metabolic syndrome (MS), respectively, and 33% (OR=1.33, 95%CI: 1.18, 1.49), 33% (OR=1.33, 95%CI: 1.18, 1.50), and 38% (OR=1.38, 95%CI: 1.21, 1.57) increase in the risk of high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), and high non-HDL-C, respectively. Similar trends were observed in males and females, with significant positive associations of logOPA with high TC and high non-HDL-C in males (P_interaction<0.05). The risk of low HDL-C decreased rapidly when logOPA was more than 2.213 (OPA>9.14 MET·h·d⁻¹), showing an inverted L-shaped trend. The risk of high TC, high LDL-C, and high non-HDL-C increased beyond logOPA thresholds of 3.244, 2.476, and 3.377 (OPA >25.64, 11.89, and 29.28 MET·h·d⁻¹), respectively, showing a J-shaped trend. However, logOPA exhibited a U-shaped nonlinear dose-response relationship with blood pressure and fasting blood glucose abnormalities (P_non-linear<0.05) , with minimal risks at logOPA 2.969 and 2.372 (OPA of 19.47 and 10.72 MET·h·d⁻¹). Conclusion OPA exhibits heterogeneous dose-response patterns across cardiometabolic indicators. Integrating the inverted L-, J-, and U-shaped association patterns, we suggest an optimal OPA range of 9.14−25.64 MET·h·d⁻¹ for multiple cardiometabolic indicators in total individuals at high-risk of CVD, with ranges of 9.61−31.34 MET·h·d⁻¹ for males and 8.97−22.87 MET·h·d⁻¹ for females. These findings provide critical evidence for developing OPA interventions strategies targeting high-risk population for CVD.

Objective To analyze the main factors influencing the management effect of rural epilepsy prevention and control projects in Hubei Province, and to provide reference for further improving the management effect. Methods According to the phenobarbital treatment and management plan of the rural epilepsy project, the target population was screened and reviewed, and patients who met the inclusion criteria were enrolled into the project management. Regular follow-up visits, free drug treatment, health education and other measures were carried out, and all relevant information was collected and integrated into the survey data. After the data was reviewed level by level, SPSS20.0 software was used for statistical analysis. Results From January 1, 2015 to December 31, 2020, among patients treated and managed with phenobarbital in 6 project counties, 1430 patients were treated and managed for more than 1 year, of whom 1119 (78.25%) had no seizures or had more than 75% reduction in the number of seizures during the observation period. Compared with other age groups, the age group of 65 years and above had the highest markedly effective/effective ratio (95.77%). From the point of follow-up, the markedly effective/effective ratio of 5 years and above was the highest (91.51%). Compared with those who received no treatment prior to enrollment and those who received regular treatment, the patients receiving informal treatment had the lowest markedly effective/effective ratio (82.43%). 1213 cases (84.83%) had good compliance during the observation period, of whom 1062 cases (87.55%) had a reduction in the number of seizures by more than 50% compared with that before treatment. Univariate analysis showed that the age of patients, the length of follow-up, the treatment status before enrollment, the average daily dose of phenobarbital and the compliance of patients all had an impact on the management effect, and the difference was statistically significant (P<0.05). Multivariate analysis showed that the markedly effective/effective rate of patients in the age group of 65 years and above was 6.749 times that of the younger age group. Receiving informal treatment prior to enrollment was a risk factor for difficult-to-control epilepsy. The markedly effective/effective rate of patients receiving informal treatment was 0.29 times that of patients never receiving treatment. Good compliance was a protective factor for epilepsy control, and the markedly effective/effective rate of patients with good compliance was 2.058 times that of patients with poor compliance. Conclusion The epilepsy prevention and management project in rural areas has a significant effect on seizure control. Early treatment, standardized treatment, and improvement of treatment compliance are effective ways to improve the management effect of epilepsy patients.

Objective:To explore the care experience of caregivers of adolescents with first-episode depres-sion.Methods:Nine family caregivers of adolescent with first-episode depression were enrolled.A qualitative re-search was carried out,and semi-structured interviews were performed to investigate the caregivers'opinion of de-pressive disorder,emotional state,caring experiences and dilemma,coping strategy,and support requirements.The data were analyzed,summarized and distilled by using the Colaizzi phenomenological 7-step analysis.Results:Four kinds of first order themes of caring experiences(complex caring experience,heavy burden of care,yearn for sup-port,achieved post-traumatic growth)were extracted,including 10 kinds of second order themes,namely shock and disbelief,pessimism and helplessness,guilt and stigma,inefficient coping strategy,impaired physical and mental health,heavy economic burden,family relationship tension,changed personal role,lack of medical support,dying to be admitted by society.Conclusion:Family caregivers of adolescent with first-episode depression may have obvious negative emotions,which faced with caring dilemma such as impaired health status or heavy economic burden,and urgently need professional resources and social support.

ObjectiveTo analyze the research status and trends in low-level occupational benzene exposure. Methods Articles on low-level occupational benzene exposure from Chinese and English journals from January 1st, 2000, to December 31th, 2022 were retrieved using the Web of Science and the China National Knowledge Infrastructure, and a bibliometric analysis was conducted. Results A total of 327 articles were included in the analysis, comprising 216 English articles and 111 Chinese articles. i) The number of articles published in English fluctuates greatly over the years, without a trend of continuous growth or decline. Authors from 359 research institutions in 45 countries and regions have published relevant English articles in 97 kinds of journals, involving 281 grants from 226 foundations. The top three countries in terms of articles amount were the United States, Italy, and China, with 81, 46, and 43 papers, respectively. The English articles mainly focused on mechanistic research at the genetic level, such as hematotoxicity, oxidative stress, and DNA damage. ii) The number of Chinese articles increased gradually after 2012, with the growth peak in 2017. Authors from 127 research institutions in 26 provinces, autonomous regions, and municipalities published Chinese articles in 51 kinds of journals, involving 154 grants from 78 foundations. Chinese articles tended to focus on benzene-induced hematotoxicity and occupational health damage. Conclusion Most studies on low-level occupational benzene exposure were conducted in China, the United States and Italy, focused on hematotoxicity. Monitoring international research topics and hotspots of the field has certain reference value for related research in China.

Background Some studies have found that exposure to heavy metals significantly increases the risk of nonalcoholic fatty liver disease (NAFLD), and welding operators in automobile manufacturing enterprises are exposed to heavy metals in the working environment. Objective To analyze the prevalence and related factors of NAFLD in workers of an automobile company in Guangzhou. Methods From January 1 of 2023 to December 31 of 2023, 5463 workers of an automobile company in Guangzhou who participated in the physical examination in the Occupational Health Surveillance Centre of Guangzhou Occupational Disease Prevention and Treatment Hospital were selected as research subjects. The general data, laboratory examinations, B-ultrasound examinations, and other data of the subjects were obtained through the physical examination system. The exposed occupational hazards were identified based on the workplace hazard surveillance report provided by the automotive company. Logistic regression was used to analyze potential influencing factors of NAFLD, and stratified analysis was used to adjust confounding factors according to the stepwise model to evaluate the relationship between exposure to manganese and its inorganic compounds and NAFLD. Results A total of 2129 cases (38.97%) were reported positive NAFLD. The results of logistic regression analysis showed that women had a lower risk of NAFLD (OR=0.40, 95%CI: 0.25, 0.64), while age > 25 years old (OR=1.49, 95%CI: 1.39, 1.60), body mass index (BMI) ≥24 kg·m⁻² (OR=7.54, 95%CI: 6.46, 8.79), and elevated alanine aminotransferase (ALT) (OR=4.87, 95%CI: 3.73, 6.36), γ-glutamyl transpeptidase (γ-GGT) (OR=1.54, 95%CI: 1.17, 2.02), triglyceride (TG) (OR=3.47, 95%CI: 2.92, 4.14), and fasting blood glucose (OR=1.70, 95%CI: 1.32, 2.20) associated with a higher risk of NAFLD. NAFLD was positive in 39.40% of heavy metal exposed workers (701/1779). NAFLD was positive in 45.19% of workers exposed to manganese and its inorganic compounds (169/374), and among workers over 34 years old, exposure to manganese and its inorganic compounds (OR=1.79, 95%CI: 1.07, 2.97) significantly increased the prevalence of NAFLD. Conclusion The association between heavy metal exposure and NAFLD in workers of an automobile enterprise in Guangzhou is not significant, but age and gender are related to the prevalence of NAFLD. BMI, ALT, γ-GGT, TG, and fasting blood glucose are positively correlated with the prevalence of NAFLD. Exposure to manganese and its inorganic compounds in welding workers of the automobile enterprise is associated with elevated risk of the disease, and the prevalence of NAFLD is significantly increased in workers over 34 years old.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To explore the status quo of pediatric nurses' cognition of death education, and analyze its influencing factors, so as to provide experience and reference for carrying out death education in pediatric wards.Methods:In this study, 827 nurses from 15 children's hospitals in China were investigated by using the scale for evaluating the cognition of death education in medical staff prepared by Zhang Yan-gai, and the related factors affecting the cognition of death education were analyzed. SPSS 23.0 was used for independent-samples t-test and ANOVA analysis, and multiple regression equation was used to further analyze the relationship between the cognitive factors of death education in pediatric nurses. Results:The total score of death education cognition of pediatric nurses was (35.61±5.64) points, which was lower than the median score of 36 points. The degree of death education cognition of pediatric nurses was at the medium-low level. The results of correlation analysis showed that the professional title of nurses (regression coefficient: 0.064, P=0.045), the training demand for death education (regression coefficient: 0.300, P<0.001), and the way of understanding (regression coefficient: 0.018, P=0.003) were independent influencing factors of the death education cognition level of pediatric nurses. Conclusions:Pediatric nurse death education related theoretical knowledge should be improved through various professional trainings. The hospitals should include death education in pediatric nurse continuing education training plan to improve pediatric nurses' cognitive level of death education through a variety of ways and means, promote the application of death education activities carried out in pediatric ward in the hospice care, reduce deaths impact to nurse their own emotions, and alleviate parents' anxiety and painful experience, thereby improving medical satisfaction.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective:To evaluate the efficacy and safety of omalizumab in the treatment of chronic urticaria in children.Methods:A retrospective study was conducted. Patients with chronic urticaria were collected from the Department of Dermatology, Hunan Children′s Hospital from January to December 2021, and divided into a control group and a combination group according to different medication regimens. The patients in the combination group received subcutaneous injections of omalizumab (150 mg, once every 4 weeks) combined with conventional-dosage antihistamines, while the patients in the control group were only treated with double-dosage or multiple types of antihistamines. The course of treatment was 3 to 6 months. The clinical efficacy and adverse reactions were evaluated at 3, 6, and 12 months after the start of treatment, and the recurrence was evaluated at 3 and 6 months after the end of treatment.Results:A total of 46 children with chronic urticaria were collected. There were 23 children (13 males and 10 females) in the combination group, aged from 6 to 17 years and including 16 aged from 6 to 12 years and 7 aged from 13 to 17 years; according to the total serum IgE levels before treatment, the patients in the combination group were divided into an increased IgE subgroup (11 cases) and a normal IgE subgroup (12 cases). In the control group, there were 13 males and 10 females, aged from 6.33 to 16 years and including 15 aged from 6 to 12 years and 8 aged from 13 to 17 years. At 3, 6, and 12 months after the start of treatment, the response rates in the combination group were all 86.96% (20/23), which were all significantly higher than those in the control group (52.17% [12/23], 56.52% [13/23], 56.52% [13/23], P = 0.010, 0.022, 0.022, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 14/16 in the children aged 6 to 12 years and 6/7 in those aged 13 to 17 years, and there were no significant differences between the two age groups (all χ2 = 0.01, P = 0.907) ; in the control group, the response rates were 5/15, 6/15 and 5/15 respectively in the children aged 6 to 12 years, which were all significantly lower than those in the combination group ( P = 0.002, 0.006, 0.006, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 9/11 in the increased IgE subgroup and 11/12 in the normal IgE subgroup, and there were no significant differences between the two subgroups (all P = 0.484). During the treatment, no serious adverse reactions were observed in the combination group or control group, and mild somnolence only occurred in 2 children in the control group. At 3 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 2 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.030) ; at 6 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 3 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.022) . Conclusion:Omalizumab combined with conventional-dosage antihistamines could improve the clinical efficacy and reduce the recurrence rate in the treatment of chronic urticaria in children, with few adverse reactions.

Objective: To examine the associations of sleep with overweight/obesity and central obesity in adults, so as to provide insights into improving sleep quality and preventing obesity in adults. Methods: Demographics, height, body weight, waist circumstance and sleep status were collected from the Hubei Provincial Surveillance Program for Adult Chronic Diseases and Their Risk Factors in 2020. Subjects' sleep condiction, overweight/obesity and central obesity were descriptively analyzed. The associations of sleep with overweight/obesity and central obesity were examined using a multivariable logistic regression model. Results: A total of 17 789 participants were recruited, with an average age of (56.21±13.05) years, 61.50% women, and mean duration of (7.18±1.56) h/d.
