Objective: To analyze the occupational health literacy (OHL) level and its influencing factors among key populations in the tertiary industry in Lu'an City, Anhui Province, so as to provide a basis for developing targeted health interventions and improving regional occupational health policies. Methods: A stratified cluster random sampling method was employed to select five categories of key populations from the tertiary industry in Lu'an City as study subjects from August to September 2024. Data on gender, age, education level, and OHL were collected through the National OHL Monitoring Questionnaire for Key Populations. The OHL levels were analyzed, and influencing factors of OHL levels among key populations were analyzed using a multivariable logistic regression model. Results: A total of 1 243 individuals were surveyed, comprising 700 (56.32%) males and 543 (43.68%) females. The median age was 42.00 (interquartile range, 17.00) years. There were 609 individuals with OHL, and the OHL level was 48.99%. The OHL levels in fundamental knowledge of occupational health protection, healthy work styles and behaviors, knowledge of occupational health laws, and basic skills for occupational health protection were 84.71%, 60.34%, 43.93%, and 37.09%, respectively. Multivariable logistic regression analysis showed that educational level (primary school and below, OR=0.149, 95%CI: 0.064-0.344; junior high school, OR=0.340, 95%CI: 0.184-0.629; high school, OR=0.408, 95%CI: 0.230-0.723), average monthly personal income (3 000-<5 000 yuan, OR=1.655, 95%CI: 1.092-2.508; 5 000-<7 000 yuan, OR=2.195, 95%CI: 1.302-3.699; ≥7 000 yuan, OR=2.062, 95%CI: 1.016-4.183), employer nature (private enterprises, OR=2.992, 95%CI: 1.569-5.443), and industry category (education, OR=3.423, 95%CI: 1.407-8.327; courier / food delivery services, OR=0.459, 95%CI: 0.268-0.787; healthcare, OR=7.539, 95%CI: 3.255-17.461) were statistically associated with the OHL level among key population. Conclusion The OHL level among key population in the tertiary industry of Lu'an City can be further enhanced, with educational level, average monthly personal income, employer nature, and industry category identified as the primary influencing factors.

General practice standardized residency training is a crucial part of postgraduate education for cultivating general practitioner. The factors influencing the quality of general practice residency training cover various aspects such as the residents themselves, teaching staff, management and decision-making levels, as well as teaching resources. Guided by the goal of "fostering virtue through education", and integrated the spirit of Norman Bethune and modern innovation theories and the educational philosophy, the China-Japan Union Hospital of Jilin University has carried out comprehensive reforms in this field. It has constructed a PDCA cycle management system based on the concept of total quality management to improve the quality of education from multiple links such as quality planning and process monitoring. In terms of faculty development, based on the dissipative structure theory, a mechanism of "selection, evaluation, incentive, and elimination" has been established. Teacher communities have been formed and a training college has been established to strengthen the teaching team. In terms of platform construction, the linkage between "teaching base-community" and "on campus-off campus" has been strengthened and resources have been integrated. The reform has achieved remarkable results, and our practice may provide a reference for general practice medical education.

Objective:To investigate the protocol and clinical efficacy of hair follicle-bearing microskin (HF-MS) transplantation in the treatment of hypertrophic scars.Methods:Prospective randomized controlled trial. From January to November 2024, patients with hypertrophic scars were recruited from the Medical Cosmetic Center of Affiliated Hangzhou First People’s Hospital with Westlake University School of Medicine and the Department of Plastic and Reconstructive Surgery of Ningbo Sixth Hospital. Patients were randomly divided into the observation group and the control group using a random number table. In the observation group, 1.0 mm punch decompression was performed on the hypertrophic scar area, followed by implantation of HF-MS extracted from the scalp donor site using follicular unit excision (FUE) into the decompression pores. The control group underwent only 1.0 mm punch decompression. Vancouver scar scale (VSS) scores (total score 0-15, higher scores indicating more severe scarring) were assessed preoperatively and at 1, 3, and 6 months postoperatively. Efficacy at 6 months, improvement in hypertrophic scar area, hair survival rate (observation group), adverse reactions, and patients’ satisfaction rates were evaluated. Categorical data were expressed as frequency (%) and analyzed using chi-square tests; normally distributed measurement data were expressed as Mean ± SD and analyzed using independent samples t-tests. Results:A total of 50 patients were included (25 per group), with 22 males and 28 females, aged 18-60 years (mean age: 33 years). The effective rate was 92% (23/25) in the observation group and 68% (17/25) in the control group, showing a statistically significant difference ( P<0.05). Preoperative VSS scores did not differ significantly between the observation and control groups [(6.67±3.19) vs. (7.12±2.89), P>0.05]. At 1, 3, and 6 months postoperatively, the observation group had VSS scores of (5.48±2.60), (4.64±2.39), and (3.80±2.10), respectively, compared to (6.36±2.53), (5.84±2.28), and (5.32±2.09) in the control group. The 6-month postoperative VSS scores differed significantly between groups ( P<0.05). Preoperative hypertrophic scar areas showed no significant difference [(5.75±2.83) cm 2 vs. (6.91±3.31) cm 2,P>0.05]. At 6 months postoperatively, the observation group had significantly smaller scar areas than the control group [(3.15±1.55) cm 2 vs. (5.37±2.93) cm 2,P<0.01]. The average hair survival rate in the observation group was 41% at 6 months. Adverse reactions occurred in 3 cases in the observation group (2 skin indurations, 1 hyperpigmentation) and 7 cases in the control group (4 hyperpigmentation, 2 skin atrophy, 1 skin induration). The observation group had a significantly lower adverse reaction rate [12% (3/25) vs. 28% (7/25), P<0.05]. Patient satisfaction rates were 88% (22/25) in the observation group and 64% (16/25) in the control group ( P<0.05). Conclusion:HF-MS transplantation demonstrates definitive clinical efficacy in treating hypertrophic scars, effectively improving scar morphology, clinical symptoms, and patient quality of life.

Objective:To study the effect of bridge orbicularis oculi muscle flap blepharoptosis in the treatment of post-burn scar contracture ectropion.Methods:The clinical data of patients wih post-burn cicatricial ectropion treated with bridge orbicularis oculi muscle flap from April 2006 to September 2020 of Department of Plastic Surgery, Affiliated Hangzhou First People’s Hospital, School of Medicine, Westlake University were analyzed retrospectively. For patients with severe eyelid scar contracture caused by head and face burns, after releasing the scar and resetting the eyelid margin, orbicularis oculi muscle flaps were made at the base of the upper and lower eyelid release incision, crossed the muscle flap over the eyelid adhesion point of the eye fissure, by performed bridge cross transfer, and fixed to the orbicularis oculi muscle at the base of the release incision to form eyelid adhesion. H-shaped full-thickness skin graft or medium-thickness skin graft was performed on the defect wound during the operation. Tie-over dressing fixation in the skin graft area. One year after the operation, it was confirmed that the skin graft was stable and there was no recurrence of ectropion, and then cut the adhesion. Follow-up for more than one year after the operation, foreign body sensation, conjunctival sac pusc, skin graft survival, success rate of eyelid adhesion, anti-stretching effect of muscle flap, skin retraction rate and complications were observed. The distances between eyelid margins preoperative and after incision of eyelid adhesion were measured. SPSS 25.0 software was used for data statistics, measurement data was represented by M ( Q1, Q3), and counting data was represented by cases. Results:Fourteen patients (23 eyes) were included in this study, including 11 males and 3 females, aged 41.5 (32.5, 47.0) years, and the time from burn to this treatment was 13.5 (10, 24) months. 5 cases (7 eyes) were not treated with skin grafting or blepharoptosis after burn, and 9 cases (16 eyes) were treated with blepharoptosis and/or skin transplantation. The area of skin graft during operation was 37 mm ×18 mm to 52 mm ×39 mm. Before operation, the distance between the upper and lower eyelid margins was 14 (12, 14) mm when eyes were open, and 6 (5, 9) mm when eyes were closed. After eyelid adhesion surgery, the patient had no foreign body sensation and infection, and all the skin grafts survived. The success rate of blepharoptosis was 100%, and there was no accidental rupture or elongation. The eyelid adhesions contracted synchronously when the patients closed their eyes, and the muscle flap had good anti-stretching effect. The duration of blepharoptosis was 13(12, 24) months, during which no complications or adverse reactions occurred. The average skin graft retraction rate was 9% (5%, 10%) in half a year. After incision of the orbicularis oculi muscle flap, the distance between the upper and lower eyelid margins was 9 (8, 9) mm when the eyes were open, and 0 (0, 0) mm when the eyes were closed.Conclusion:Bridge orbicularis oculi muscle flap tarsorrhaphy can provide long-term tarsorrhaphy, effectively reduce skin contracture after eyelid skin grafting, and has a stable therapeutic effect on postburn ectropion.
