AIM: To investigate the specific molecular mechanism of Yinqiao Powder in affecting macrophage polarization in herpes simplex keratitis(HSK)through the cyclic GMP-AMP synthetase(cGAS)-stimulator of interferon genes(STING)-interferon regulatory factor 3(IRF3)molecular pathway.METHODS:Human corneal epithelial cells(HCE-T)were divided into control, HSK, and HSK + Yinqiao Powder groups. M0 macrophages were grouped as Ctrl, HSV-1, HSV-1+oe-cGAS, HSV-1+Yinqiao Powder, and HSV-1+oe-cGAS+Yinqiao Powder. Conditional medium(CM)from each group of M0 macrophages was collected to intervene in HCE-T cells and divided into Ctrl-CM, HSV-1-CM, HSV-1+oe-cGAS-CM, and HSV-1+Yinqiao Powder-CM groups. Cell viability was detected by MTT assay, and apoptosis was detected by TUNEL assay. ELISA was used to detect the concentrations of Arg-1 and iNOS in cell supernatants, and Western blotting was used to detect the relative protein expressions of cGAS, STING, and IRF3. Balb/c mice were divided into control, model, and drug groups. The model and drug groups were inoculated with HSV-1 on the cornea of Balb/c mice using the corneal scratch method to construct an HSK mouse model, and the drug group was treated with Yinqiao Powder. The incidence and mortality of the three groups were compared on days 1, 3, 5, 7, and 14 after modeling.RESULTS:Compared with the control group, the HCE-T cell viability in the HSK group was decreased but apoptosis was increased, which was reversed by Yinqiao Powder intervention. Compared with the Ctrl group, the Arg-1 concentration in the cell supernatant of the HSV-1 group was decreased, the iNOS concentration was increased, and the protein expressions of cGAS, STING, and IRF3 were decreased. Compared with the HSV-1 group, the Arg-1 concentration was increased, the iNOS concentration was decreased, and the protein expressions of cGAS, STING, and IRF3 were enhanced in the HSV-1+oe-cGAS group and the HSV-1+Yinqiao Powder group, and the same results were obtained in the HSV-1+oe-cGAS+Yinqiao Powder group. Compared with the Ctrl-CM group, the HCE-T cell viability was decreased and apoptosis was increased in the HSV-1-CM group, which was reversed by overexpressing cGAS in macrophages or intervening with Yinqiao Powder. In vivo experiments found that Yinqiao Powder intervention could improve the pathological progression of keratitis.CONCLUSION:Yinqiao Powder inhibits M1 polarization of macrophages through the cGAS-STING-IRF3 molecular pathway, thereby delaying the progression of HSK.

Objective: To investigate the status of passive smoking among pregnant women in Jinshan District, Shanghai Municipality, so as to provide insights into developing targeted smoking control measures and promoting maternal and infant health. Methods: Pregnant women who had early pregnancy registration at Jinshan District Community Health Service Center from April 2021 to December 2023 were selected as subjects. The basic information, passive smoking and awareness of passive smoking hazards among pregnant women were collected through questionnaire surveys, and passive smoking rate and awareness rate of passive smoking hazards were analyzed. Results: Totally 8 273 questionnaires were allocated, and 8 216 valid questionnaires were recovered, with an effective rate of 99.31%. The mean age of participants was (29.52±4.60) years. There were 4 991 participants with an education of college degree or above, accounting for 60.75%; 3 565 participants with the first pregnancy, accounting for 43.39%; 3 990 primiparas, accounting for 48.56%; 3 193 participants living with smokers, accounting for 38.86%. A total of 3 710 participants passively smoked, with a passive smoking rate of 45.16%. There were 2 817 participants passively smoked in public places, accounting for 75.93%; 2 253 participants passively smoked in workplaces, accounting for 60.73%; 1 563 participants that passively smoked at home, accounting for 42.13%. The awareness rates regarding the hazards of passive smoking to health, causing lung cancer in adults, causing lung diseases in children, causing preterm birth and low birth weight infants, and causing heart diseases in adults were 92.13%, 88.85%, 87.99%, 82.05% and 62.56%, respectively. Conclusion The rate of passive smoking among pregnant women in Jinshan District is comparatively high, while their awareness regarding non-respiratory diseases emanating from passive smoking is comparatively low.

Two researchers conducted quality evaluation, evidence extraction, and summarization of the included literature.Results:A total of 10 articles were included, including six expert consensus articles, three systematic review articles, and one meta-analysis article. A total of 16 pieces of evidence were summarized from nine aspects of rehabilitation exercise evaluation, principles, timing, methods, health education, psychotherapy, pain management, evaluation and post discharge follow-up.Conclusions:This study summarizes the best evidence for rehabilitation exercise in patients with lumbar spinal stenosis after surgery, and it suggests that healthcare professionals apply evidence based on clinical context and patient willingness.

Objective:To explore the clinical effects of the best evidence-based practice plan for rehabilitation exercises in patients undergoing surgery for lumbar spinal stenosis (LSS) .Methods:Guided by the evidence-based practice model of the Joanna Briggs Institute (JBI) Center for Evidence-Based Healthcare in Australia, the best evidence was combined with the clinical context to develop quality review indicators for clinical practice. In December 2022, a baseline review was conducted with 30 patients undergoing surgery for LSS (before evidence application). From December 2022 to February 2023, the baseline review results were analyzed to identify facilitating and obstructive factors between the current status and the review indicators, and improvement strategies were implemented based on available resources. In February 2023, another 30 patients (after evidence application) were selected to evaluate the post-application effects. The Japanese Orthopedic Association (JOA) score, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia (TSK) score, General Self-Efficacy Scale (GSES) score, and quality of life scores were compared between the two groups at 24 hours, 1 month, 3 months, and 6 months postoperatively. The execution rate of clinical quality review indicators and the knowledge scores on rehabilitation exercises of 25 nurses before and after training were also compared.Results:There were no statistically significant differences in JOA scores, ODI, TSK scores, GSES scores, and quality of life scores between the two groups at 24 hours postoperatively ( P > 0.05). However, there were statistically significant differences in these scores at 1, 3, and 6 months postoperatively ( P< 0.01). After evidence application, the execution rate of seven clinical quality review indicators improved, and the knowledge scores on rehabilitation exercises of the 25 nurses increased significantly ( P< 0.05) . Conclusions:The evidence-based practice for rehabilitation exercises in patients undergoing surgery for LSS is safe and feasible. It standardizes evidence-based nursing practice behavior, enhances nurses' knowledge levels, effectively improves postoperative lumbar function, promotes physical rehabilitation, and enhances the quality of life.

The non-randomized controlled study design was adopted. A total of 90 patients with knee osteoarthritis treated in Beijing Yuetan Community Health Service Center from September 2021 to August 2022 were enrolled in the study, including 45 patients received patellar loosening and then the quadriceps femoris pain point release (successive group) and remaining 45 patients received two manipulations simultaneously (simultaneous group). Patients were treated 3 times in a week, and each time received 5 groups of manipulation. The Visual Analogue Scale (VAS) and Lysholm scores were measured before treatment, immediately after treatment and 3 months after treatment. There was no exfoliation and no adverse events in both groups. There were no significant differences in VAS and Lysholm scores between the two groups before treatment ( P>0.05). Immediately after treatment, the VAS pain score in the simultaneous group was lower than that in the successive group ((3.36±1.12) vs.(2.24±0.93), P<0.01), while the Lysholm score in the simultaneous group was higher than that in the successive group ((89.76±6.61) vs.(74.07±16.80), P<0.01); the proportion of VAS score as“painless/mild pain”(88.9% (40/45) vs.64.4% (29/45), P<0.01) and Lysholm score as “excellent/good”(91.1% (41/45) vs. 44.4% (20/45), P<0.01) in the simultaneous group was significantly higher than that in the successive groups. At 3 months after treatment, there were still significant differences in VAS and Lysholm scores between the two groups. The simultaneous manipulations of patellar loosening and quadriceps femoris pain point release can better relieve the pain of patients with knee osteoarthritis.

{L-End}Objective To analyze the correlation between occupational burnout and sleep quality among steelworkers. {L-End}Methods A total of 11 491 steelworkers from a large steel enterprise in Gansu Province were selected as the research subjects using convenient sampling method. The Burnout Questionnaire and the Pittsburgh Sleep Quality Index Scale were used to investigate their occupational burnout and sleep quality. Hierarchical regression analysis was used to analyze the effects of occupational burnout on the sleep quality. {L-End}Results The detection rate of occupational burnout and sleep disorder were 50.4% and 39.0%, respectively. There was a positive correlation between the level of occupational burnout and the total score of sleep quality (Spearman correlation coefficient=0.454, P<0.05). The results of hierarchical regression analysis, adjusting for confounding factors such as gender, age, marital status, education level, alcohol consumption, exercise, weekly working hours, seniority, work shift, noise exposure, dust exposure, and high-temperature work, showed that the score of occupational burnout was positively related to the score of sleep quality(P<0.01), explaining 16.0% of the variance in the score of sleep quality among these steelworkers. {L-End}Conclusion The detection rate of occupational burnout and sleep disorders are relatively high among the steelworkers in this enterprise. Higher levels of occupational burnout are associated with poorer sleep quality. Alleviating occupational burnout among steelworkers may contribute to improving their sleep quality.

ObjectiveTo investigate the psychological tendency characteristics of vocational selection for college students with disabilities. MethodsA total of 155 college students with disabilities in four colleges and universities were investigated using Psychological Tendencies of Vocational Selection for College Students with Disabilities (PTVS). ResultsA total of 151 questionnaires returned finally. The principal component analysis extracted four factors, namely profession, capability, parental occupation and parental education, with a cumulative contribution rate of 74.98%. Clustering analysis clustered three categories, namely vocational capability and parental education dominated, profession and capability dominated, and profession dominated, which accounted for 20.5%, 31.1% and 48.3%, respectively. There were significant differences among the three categories in the dimensions of personal cognition, employment tendency, employment affect and employment will of PTVS (F > 7.021, P < 0.01). ConclusionThere are four dimensions of PTVS, i.e., the dimension of profession, the dimension of capability, the dimension of parental occupation and the dimension of parental education; while the PTVS could be divided into three categories, i.e., vocational capability and parental education dominated, profession and capability dominated, and profession dominated. For college students with disabilities, accurate career counseling and guidance should be provided according to the psychological structure of vocational selection and PTVS.

Background Steel workers are exposed to occupational hazardous factors such as dust, noise, and heat, and often work in shifts, making them prone to sleep disorders. Objective To explore potential influencing factors of sleep disorders among workers in a steel enterprise in Gansu Province, and provide a basis for reducing the risk of sleep disorders among them. Methods From January to March 2022, a self-made questionnaire combined with the Pittsburgh Sleep Quality Index (PSQI) were used to investigate the employees of a steel enterprise in Gansu Province. According to their PSQI scores, they were divided into a normal sleep group and a sleep disorder group. The general demographic variables of the two groups were balanced by 1∶1 propensity score matching (PSM). Multiple logistic regression was used to analyze the contributing factors of sleep disorders. Restricted cubic spline (RCS) model was used to analyze potential dose-response relationship between weekly working hours and sleep disorders. Results The prevalence of sleep disorders in the steel workers was 48.06% (6029/12544). After PSM, 5847 pairs were successfully matched, and the distributions of matched variables were well balanced between the two groups. The results of multiple logistic regression showed that hypertension (OR=1.39, 95%CI: 1.24, 1.56), diabetes mellitus (OR=1.34, 95%CI: 1.07, 1.66), three-shift system (OR=1.26, 95%CI: 1.12, 1.41), dust exposure (OR=1.14, 95%CI: 1.01, 1.29), noise exposure (OR=1.23, 95%CI: 1.09, 1.39), heat exposure (OR=1.16, 95%CI: 1.04, 1.29), and work injury (OR=1.22, 95%CI: 1.02, 1.46) increased the risk of sleep disorders. Compared with workers with < 10 years of service, those with 10-20 years (OR=1.31, 95%CI: 1.19, 1.44), 20-30 years (OR=1.34, 95%CI: 1.19, 1.52), and ≥30 years of service (OR=1.35, 95%CI: 1.19, 1.53) had a higher risk of sleep disorders. Compared with non-exercise workers, the risk of developing sleep disorders was lower in workers with occasional exercise (OR=0.61, 95%CI: 0.56, 0.66) and regular exercise (OR=0.55, 95%CI: 0.49, 0.62). The RCS model showed that the weekly working hours and sleep disorders in the steel workers showed a nonlinear dose-response relationship (P<0.05 for overall trend, P<0.05 for nonlinear test). The relationship between weekly working hours and sleep disorders showed a "U" shaped distribution, with a significant increase in the risk of sleep disorders when the weekly working hours exceeded 49 h. Conclusion The non-occupational influencing factors of sleep disorders of employees in the steel enterprise include hypertension, diabetes, physical exercise, and occupational influencing factors include length of service, weekly working hours, shifts, dust exposure, noise exposure, heat exposure, and work injuries. It is recommended to consider both occupational and non-occupational factors to formulate appropriate sleep disorder prevention and control measures for steel employees to reduce the risk of sleep disorders.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective To compare the difference of volatile organic compounds (VOCs) in the urine of diabetic patients comorbid with or without depression. Methods Patients with type 2 diabetes who met the diagnostic criteria of prevention and treatment guidelines and were treated in inpatient department of Sixth People’s Hospital South Campus, Shanghai Jiaotong University, from November 2019 to November 2020 were included in the study. Depression screening was performed using PHQ9 scale. According to the scores, the patients were divided into two groups: diabetic patient group and diabetic patient comorbidity depression group. The morning urine was collected and VOCs in urine were detected using a miniature gas tester. Results A total of 161 patients with diabetes mellitus, including 141 patients in the diabetic group and 20 patients in the diabetic comorbidity depression group. The results indicated that the sensitivity, specificity and accuracy of the method are 80%, 98% and 92.8% respectively. There were differences in urine volatile organic compounds between the two groups. Conclusions Compared with diabetic patients, the composition of volatile organic compounds in urine may change after diabetic comorbidity depression, which can provide experimental reference for early clinical diagnosis of depression.
