Objective To explore an artificial intelligence (AI)-based method for automated hand hygiene monitoring and to compare the effectiveness of three algorithms (UniFormerV2, TDN, C3D) in recognizing hand hygiene steps in surgical settings, thereby aiding hospital infection control. Methods From April to October 2024, we non-invasively collected 641 video recordings of healthcare staff performing hand hygiene at four-bay scrub sinks in two tertiary hospitals using overhead HD cameras. The dataset was annotated by five trained experts for model training and validation. Results Following training on 385 samples, internal validation (n=119) showed the C3D model achieved 81% accuracy, 87% recall, and an 83% F1-score. The TDN model achieved 93%, 91%, and 92% for the same metrics. The UniFormerV2 model outperformed both, with an accuracy, recall, and F1-score of 93%—an improvement of over 10 percentage points compared to traditional CNNs (TDN, C3D). It also achieved an 84% accuracy in external validation, demonstrating strong generalization. Conclusion The UniFormerV2 model is more accurate than CNN-based models for hand hygiene step recognition and shows robust performance in external validation. It presents a viable tool for healthcare facilities to enhance hand hygiene management, ultimately improving medical quality and patient safety.

Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

Objective: To analyze the prevalence and determinants of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou City, and to explore the association between sleep patterns, eating behavior and the comorbidity of overweight/obesity and elevated blood pressure, so as to provide reference for developing prevention strategies targeting common comorbidities in students. Methods: By using stratified cluster random sampling, a total of 8 735 primary and secondary school students were selected from 36 schools in six counties of Yangzhou from October to November 2023. Students underwent physical examinations and a questionnaire survey was conducted using the questionnaire on students health status and influencing factors. The Chi square test was used to compare the detection rate of comorbid overweight/obesity and elevated blood pressure in different groups of primary and secondary school students. The Logistic regression model was used to explore the association between sleep and dietary behaviors and their combined effects and coexistence. Results: The detection rate of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou was 9.85%, which was higher among boys (12.14%) than girls (7.59%)( χ 2=50.86, P <0.01). After controlling for gender, residence, educational stage, parental education, smoking, drinking, and moderate to vigorous exercise, multivariate Logistic regression analysis showed that irregular breakfast consumption and inadequate daily sleep were associated with a higher risk of comorbidities compared with regular breakfast consumption and adequate daily sleep among overall and primary school students (overall: OR =1.52, 95% CI =1.18- 1.96 , primary school students: OR =2.79, 95% CI =1.61-4.82)(both P <0.05). From the perspective of primary school students of different genders, the risk of comorbidities in girls who consumed breakfast irregularly and had inadequate daily sleep was 3.59 times higher than that in girls who consumed breakfast irregularly and had inadequate daily sleep (95% CI =1.65-7.82, P <0.01). Conclusion The sleep patterns and breakfast behaviors of primary and secondary school students are found to be associated with comorbid overweight/obesity and elevated blood pressure, especially in primary school girls.

Objective To evaluate the efficiency of health resource allocation in 22 types of hospital institutions in Guangdong Province from 2018 to 2022,identify their strengths and shortcomings in resource utilization,and offer evidence-based recommendations for optimizing medical resource allocation and policymaking.Methods The efficiency of health resource allocation was assessed using the DEA-BCC model and the DEA-Malmquist index model across the 22 hospital categories.Results In 2022,the overall resource allocation efficiency of the 22 types of hospital institutions in Guangdong Province was suboptimal,with an average score of 0.657.From 2018 to 2022,the mean total factor productivity(TFP)change index for these hospitals was 0.968,with only 6 categories exhibiting a TFP index exceeding 1.Conclusion The efficiency of health resource allocation in Guangdong's hospitals remains inadequate.Government authorities should enhance macro-level planning for regional resource distribution,accelerate advancements in medical technology,and establish a real-time monitoring framework.Concurrently,policy interventions and incentive mechanisms should be reinforced to ensure both scientifically sound allocation and effective utilization of medical resources.

AIM: To assess the clinical efficacy of visual therapy in children with abnormal visual functions and asthenopia.METHODS: Retrospective case study. The data of 57 patients(114 eyes), aged 8.25±1.94 years, who underwent visual training at the optometry center of Xi'an Children's Hospital between January 2022 and April 2023, were collected. Patient assessments before and after training included refractive errors, a visual fatigue scale questionnaire, and visual function tests. These tests included the Worth 4 Dot for binocular vision, the Von Graefe method for measuring latent strabismus at distance and near, the gradient method for assessing the accommodative convergence/accommodation(AC/A)ratio, the push-up test for convergence near point, the negative lens method for amplitude of accommodation, the cross-cylinder test for accommodative response, and the flipper test for accommodative flexibility. Training programs were tailored based on the initial assessments of visual function and asthenopia. Comparisons were made between pre-training, 1 and 3 mo post-training evaluations.RESULTS: At baseline and 1 mo post-training, the visual fatigue scores were 26.00±6.77 and 19.57±8.90, respectively(P<0.05). Significant enhancements were observed in near phoria, convergence near point, and accommodative amplitude in both eyes, both negative relative accommodation(NRA)and positive relative accommodation(PRA), as well as accommodative flexibility in both eyes at 1 mo after therapy(all P<0.05), while no significant changes were found in distance phoria or accommodative response(all P>0.05). Furthermore, no significant differences were noted in the binocular amplitude of accommodation, NRA, PRA, and near phoria between 1 and 3 mo after training(all P>0.05). The visual function parameters of 30 patients with low myopia(SE: -1.99±1.22 D), 3 patients with low hyperopia(SE: +1.01±0.13 D)and 24 patients with emmetropia(SE: +0.25±0.11 D)were not statistically significant before training and at 1 mo after training(all P>0.05). Certain visual functions significantly improved at 1 mo after training, and most had returned normal by 3 mo.CONCLUSION: Vision therapy significantly enhances binocular visual function and alleviates symptoms of asthenopia in children with visual dysfunction. It is an effective, straightforward, and easily applicable method for relieving children's visual fatigue.

AIM:To test and compare the perceptual eye position and fixation stability of adolescents with emmetropia and adolescents with low myopia, investigating the characteristics of the perceptual eye position and fixation stability of adolescents with low myopia.METHODS: Cross-sectional study. A total of 132 adolescents(264 eyes)who visited in the ophthalmology clinic of our hospital from April to December 2023 were randomly selected as the research subjects. Participants were categorized into normal control group(n=45, 90 eyes), simple low myopia group(n=45, 90 eyes)and low myopia with anisometropia group(n=42, 84 eyes)according to their refractive status and were underwent assessments for perceptual eye position and fixation stability.RESULTS: Compared with the normal control group, the static and dynamic horizontal perceptual eye position deviation of the simple low myopia group and the low myopia with anisometropia group were significantly increased(P<0.05). Compared with the simple low myopia group, the static and dynamic horizontal perceptual eye position deviation of the low myopia with anisometropia group were significantly increased(P<0.05). There was no significant difference in static and dynamic vertical perceptual eye position deviation among the three groups(P>0.05); compared with the normal control group, the horizontal and vertical fixation stability of the simple low myopia group and the low myopia with anisometropia group were significantly worse(all P<0.01), but there was no differences in the simple low myopia group and the low myopia with anisometropia group(P >0.05).CONCLUSION: Abnormalities are observed in perceptual eye position and fixation stability function in adolescents with low myopia compared with those adolescents with emmetropia, even at best corrected visual acuity. The occurrence of anisometropia could lead to an increased degree of horizontal perceptual eye position displacement.

【Objective】 To understand factors associated with children′s attendance at nursery care institutions (NCIs) and the basic characteristics of the NCIs children were enrolled in, so as to provide scientific evidence for policymakers. 【Methods】 During November 2020 and January 2021, parents who visited the Department of Child Health Care in six selected maternal and children′s hospitals, as well as nearby NCIs in Zhejiang were invited to finish an online questionnaire. Information such as children′s sociodemographic characteristics, parents′ knowledge, attitude and practice regarding nursery and feeding, etc. were collected. A total of 1 756 questionnaires were collected. 【Results】 Compared to children who were not in NCIs, children enrolled in NCIs were older (94.4% of children ≥24 months vs. 30.1%, χ²=835.27), more likely to be from the local area (87.2% vs. 81.4%,χ²=12.25), more likely to have parents with a college degree (mother: 83.6% vs. 74.2%, χ²=35.29; father: 79.9% vs. 70.0%, χ²=27.01), had a higher prevalence of family annual income >200 000 CNY (49.5% vs. 28.2%, χ²=110.49), and were less likely to have their grandparents available to take care of them (16.7% vs. 26.8%, χ²=31.4) The difference all have great significant.(P<0.05). In a multivariate Logistic regression model, the older the child, the more likely they were to attend an NCI (for children aged 6 - 23 months, OR=6.70; for children aged 24 - 35 months, OR=134.03; and for children aged 36 - 42 months, OR=699.33; P<0.05). Family annual income was positively associated with children′s attendance at NCIs (for those earning 100 000 - 200 000 CNY/year, OR=1.63; for those earning 200 000 - 500 000 CNY/year, OR=2.96; and for those earning >500 000 CNY/year, OR=4.62, P<0.05). Conversely, the higher the level of grandparent involvement in daily care, the lower the attendance at NCIs (for children cared for by both parents and grandparents, OR=0.57; for those primarily cared for by grandparents, OR=0.26, P<0.05). For children who used to stay at NCIs, 82.8% stayed at institutions that only recruited children aged 0 - 3 years, 97.4% spent their whole day in NCIs, and 71.4% spent less than 3 000 CNY per month for NCI services. Additionally, over 95% of parents were satisfied with the food and care services in NCIs, as well as their children′s physical development in NCIs. However, 32.1% of NCIs were reported by parents as having no room for breastfeeding. 【Conclusions】 Children′s age, grandparent involvement in routine care, and family annual income are the main factors associated with children′s attendance at NCIs. There is a greater need for more affordable and community-based NCIs, particularly for children under 2 years old. Additionally, more attention should be paid to the quality surveillance, assessment and management of NCIs.

Objective:To explore the application effect of integrated Chinese and Western medicine nursing based on the individual and family self-management theory (IFSMT) in patients with urinary incontinence after stroke, and provide reference for clinical nurses to effectively rehabilitate these patients.Methods:This was a quasi-experimental study. A total of 136 patients with urinary incontinence after stroke who were hospitalized in the Department of Encephalopathy of Shanxi Acupuncture and Moxibology Hospital from February 2022 to May 2023 were selected as the study objects by convenience sampling method. The subjects were divided into the control group and the experimental group with 68 cases in each group by random number table method. The control group received routine rehabilitation nursing, and the experimental group received integrated Chinese and western medicine nursing based on IFSMT on the basis of routine rehabilitation nursing. Urinary status, activities of daily living and quality of life of 2 groups were compared.Results:Ultimately, there were 68 cases were admitted in each group. In the control group, male 45 cases, female 23 cases, aged (62.35 ± 4.94) years old. In the experimental group, male 49 cases, female 19 cases, aged (61.94 ± 5.02) years old. There was no statistical significance in urinary status, activities of daily living and quality of life scores between the 2 groups before the intervention (all P>0.05). After the intervention, the average daily urination frequency of experimental group was (7.94 ± 1.08) times, which was lower than that of control group (9.88 ± 1.09) times; the average daily frequency of incontinence in the experimental group was (3.63 ± 1.65) times, lower than (5.03 ± 3.35)times in the control group; the average daily urine volume of experimental group was (107.34 ± 4.15) ml, higher than (89.62 ± 19.71) ml of control group, and the differences were statistically significant ( t=10.46,3.09, -7.23, all P<0.05). The scores of activities of daily living in the experimental group was (60.44 ± 3.65) points, which were higher than (46.24 ± 3.29) points in the control group; the Incontinence Quality of Life Questionnaire score of experimental group was (80.38 ± 4.65) points, which was higher than (64.62 ± 5.62) points of control group; Insomnia Severity Index-Short Form score of the experimental group was (10.94 ± 5.17) points, which was lower than (12.85 ± 4.30) points of the control group, and the differences were statistically significant ( t=23.85, -17.86, 2.34, all P<0.05). Conclusions:Integrated Chinese and western medicine nursing intervention based on IFSMT has a positive effect on patients with urinary incontinence after stroke, and can significantly improve patients' urination and daily living activities, thus improving patients' quality of life.

Objective:To investigate the clinical efficacy and mechanism of Ganoderma lucidum hypoglycemic formula in the treatment of insulin resistance in patients with type 2 diabetes mellitus (T2DM) with liver and kidney yin deficiency. Methods:A total of 86 patients with T2DM with liver and kidney yin deficiency who were diagnosed and treated at Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine from January 2021 to February 2022 were included in this study. These patients were divided into a control group and a treatment group, with 43 patients in each group using a 1:1 ratio using the sealed envelope method. Both groups were treated with standardized Western medicine. The treatment group was also treated with the Ganoderma lucidum hypoglycemic formula. All patients were followed up for 12 weeks. The clinical symptoms, curative effect, glucose and lipid metabolism, inflammatory factors, oxidative stress change, and safety were compared between the two groups. Results:The total response rate in the treatment group was 88.4% (38/43), which was significantly higher than 53.5% (23/43) in the control group ( χ2 = 12.69, P < 0.001). After treatment, the traditional Chinese medicine syndrome score, fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, insulin resistance index, total cholesterol, triglyceride, tumor necrosis factor α, and interleukin-6 decreased in each group. The amplitudes of decrease of the above indexes were greater in the treatment group compared with the control group (all P < 0.05). C-peptide in the fasting state, C-peptide at 2 hours after a diet, and superoxide dismutase increased in each group. The amplitudes of increase of the three indexes were greater in the treatment group compared with the control group (all P < 0.05). Conclusion:Ganoderma lucidum hypoglycemic formula can greatly improve insulin resistance and glucose and lipid metabolism in T2DM patients with liver and kidney yin deficiency. The underlying mechanism may be to further reduce the inflammatory response and anti-oxidative stress by down-regulating tumor necrosis factor α and interleukin-6 levels and up-regulating superoxide dismutase level, thereby effectively alleviating insulin resistance in T2DM.
