Objective:
To assess the nutritional supply status of school meals for primary and secondary school students in Henan Province, so as to provide a basis for scientific guidance of school meals.
Methods:
During 2021-2023, 115 lunch and dinner samples were collected from 25 primary and secondary schools in Zhoukou, Anyang and Luoyang of Henan Province by a direct selection method, and 13 nutrients were determined for each sample. The nutrient supply was evaluated based on Nutrition Guidelines of School Meals and Reference Intake of Dietary Nutrients for Chinese Residents (2023 Edition). Mann-Whitney U test was used to compare the differences of nutritional supply between urban and rural schools.
Results:
The median values for energy (709.77 kcal,1 kcal=4.18 kJ), fat energy supply ratio (0.27) and carbohydrate energy supply ratio (0.55) in the 66 lunches and dinners from primary school were within the recommended range. The supply of protein (28.39 g) and sodium (1 464.59 mg) was excessive. The median values of zinc (2.62 mg) and dietary fiber (5.19 g) were lower than the reference values. No statistically significant differences were observed in the supply of 13 nutrients between urban and rural primary schools( U = 427.00 -633.00, P > 0.05 ). Among 49 samples from secondary schools, the median value of energy supply (930.02 kcal), carbohydrate energy ratio ( 0.54 ) and fat energy supply ratio(0.25) were within the recommended range; and the median values of protein (38.82 g) and sodium (2 556.80 mg) were higher than the standard; and the median values of calcium (250.32 mg) and vitamin B1 (0.16 mg) were lower than the standard. Additionally, the differences in the level of vitamin B2 ( U =372.00) and zinc ( U =375.00) between the urban and rural secondary schools were statistically significant ( P <0.05).
Conclusion
Nutrient supply of primary and secondary school meals in three cities of Henan Province is inadequate and imbalanced, and the recipe need to be further optimized and improved.

Objective:To examine the relationships between perceived organizational support in job resources, self-efficacy in personal resources, and teaching commitment based on the job requirement-resource model, and to explore the path of influencing clinical teachers' teaching commitment.Methods:Using the convenience sampling method, 463 clinical teachers from 16 university-affilicated hospitals in Shandong Province, China were selected as the study subjects. Surveys were conducted using the Perceived Organizational Support Scale, Self-efficacy Scale, and Teaching Commitment Scale. A statistical analysis was performed using SPSS 26.0. A structural equation model was constructed using AMOS 26.0 to test the mediation effect.Results:①The level of teaching commitment of clinical teachers was relatively high, with a total score of (45.25±9.21) points. The total score of perceived organizational support was (38.22±9.75) points, and the total score of self-efficacy was (112.27±17.30) points. ②Perceived organizational support and self-efficacy were positively correlated with teaching commitment ( r=0.59, r=0.65, both P<0.01). ③ Perceived organizational support had significant and direct positive effects on teaching commitment and self-efficacy ( β=0.36, β=0.51, both P<0.01). Self-efficacy significantly and positively affected teaching commitment ( β=0.47, P<0.01). Self-efficacy played a significant and partial mediating role in the effect of perceived organizational support on teaching commitment (standardized mediating effect value of 0.239, P<0.01), and the mediating effect percentage was 39.83%. Conclusions:Perceived organizational support not only directly predicts clinical teachers' teaching commitment, but also indirectly affects teaching commitment through self-efficacy. University-affiliated hospital administrators should pay attention to clinical teachers' perceived organizational support to improve their self-efficacy and teaching commitment, thereby ensuring teaching quality.

Objective:To analyze the anatomical characteristics and surgical management measures of acute Stanford type A aortic dissection (AAD) involving coronary arteries, and to preliminarily explore the clinical efficacy of different coronary artery treatment techniques.Methods:A retrospective analysis was conducted on the clinical data of 42 patients who underwent surgery for AAD involving coronary arteries in Hunan Provincial People′s Hospital from January 2022 to May 2025. They were divided into the MI group (14 cases) and the nMI group (28 cases) according to whether they had acute myocardial infarction before surgery. The clinical data such as the actual surgical methods and mortality in the two groups were summarized.Results:Among 294 surgeries, 42 cases (14.3%) had definite coronary artery involvement, including 14 cases in the MI group and 28 cases in the nMI group; 1 case had bilateral coronary artery involvement and 41 cases had right coronary artery involvement. Regarding injury types: 16 cases were of the coronary trunk compression type, 12 cases were of the sinus intimal tear neal to ostium type, and 14 cases were of the coronary trunk intimal type. There was no statistically significant difference in the types of coronary artery involvement between the two groups ( P>0.05). There were 18 cases of Sun′s procedure with preserved aortic sinus and aortic valve, 7 cases of Bentall procedure without bypass, and 17 cases of Bentall procedure plus bypass. There was no statistically significant difference in the surgical plans between the two groups ( P>0.05). There were 4 deaths within 30 days (2 cases in each group). Conclusions:AAD involving coronary arteries is a critical condition, and accurate diagnosis is somewhat difficult. Myocardial ischemia is not significantly associated with the type of coronary artery involvement. The surgical plan depends on the type of coronary artery involvement. The classification method in this study is conducive to selecting appropriate surgical methods and improving surgical prognosis.

Objective:To examine the influence of physical function status on supportive care needs (SCNS) in patients with primary liver cancer (PLC) and to explore the mediating roles of perceived social support and anxiety-depression, with the aim of providing evidence for nursing interventions to improve patients' care experience.Methods:A convenience sampling method was used to select PLC inpatients admitted to The First Affiliated Hospital of Jinan University between December 2022 and February 2024. Data were collected using a general information questionnaire, the 34-item Supportive Care Needs Survey-Short Form, the Hospital Anxiety and Depression Scale, the Perceived Social Support Scale, and the Karnofsky Performance Status Scale to conduct a cross-sectional survey. Pearson correlation analysis was performed to examine associations among SCNS, perceived social support, anxiety-depression, and physical function status. Structural equation modeling was used to assess the mediating effects of perceived social support and anxiety-depression on the relationship between physical function status and SCNS.Results:A total of 304 patients were enrolled, including 260 males and 44 females, 31 cases aged 18-40 years old, 160 cases aged 41 to 60 years old, and 113 cases over 60 years old. The mean total SCNS score was (98.32 ± 21.75) points, the mean anxiety-depression score was (23.31 ± 9.64) points, the mean perceived social support score was (56.62 ± 13.05) points, and the mean physical function status score was (66.28 ± 12.31) points. Pearson correlation analysis showed that physical function status was negatively correlated with SCNS and anxiety-depression ( r =-0.509, -0.447; both P<0.05) and positively correlated with perceived social support ( r =0.439, P<0.05). Physical function status had a direct effect of 60.74% on SCNS, with specific mediating effects of perceived social support and anxiety-depression accounting for 23.15% and 11.85%, respectively, and a chain mediating effect of 4.26%. Conclusions:Patients with PLC exhibited a moderately high level of supportive care needs. Physical function status not only exerted a direct negative effect on SCNS but also indirectly influenced SCNS through the chain mediation of perceived social support and anxiety-depression. Clinical medical staff should focus on enhancing patients' perception of social support and effectively alleviating anxiety and depressive symptoms, thereby reducing supportive care needs to some extent.

Objective:To construct and verify a risk prediction model for pulmonary infection in patients with aneurysmal subarachnoid hemorrhage (aSAH) after craniotomy and clipping, providing theoretical basis and practical guidance for improving the quality of postoperative care.Methods:Using the convenience sampling method, a retrospective selection was made of 397 patients with aSAH after craniotomy and clipping who were hospitalized in the Department of Neurosurgery of Shanxi Bethune Hospital (Shanxi Academy of Medical Sciences) from January 2019 to December 2023 as the modeling group. They were randomly divided into the training set and the test set at a ratio of 7:3, with 278 cases in the training set and 119 cases in the test set. Patients were divided into the infection group and the non-infection group based on whether they developed pulmonary infection. Univariate analysis was used to model the risk factors of pulmonary infection after aSAH craniotomy and clamping in the group, and Lasso regression was used to construct a predictive model. A total of 119 patients with aSAH admitted to the neurosurgery department of the same hospital from January to April 2024 were selected for the external validation of the model. The predictive effect of the model was evaluated through the receiver operating characteristic (ROC) curve.Results:In the modeling group, there were 216 male patients and 181 female patients. The incidence of pulmonary infection was 38.54% (153/397). Finally, five influencing factors, namely stroke, Hunt-Hess classification, mechanical ventilation, indwelling nasogastric tube and the timing of initiating enteral nutrition, were included to construct a predictive model. The areas under the ROC curves of the nomogram prediction models of this model in the training set, test set, and external validation group were 0.859(95% CI 0.791-0.928), 0.843(95% CI 0.796-0.890), and 0.800(95% CI 0.711-0.889), respectively. The calibration curve shows that the model's prediction fits well with the actual situation and has a high degree of calibration. Decision curve analysis indicates that this model has high clinical application value under different risk thresholds. Conclusions:The risk prediction model for pulmonary infection in patients after craniotomy and clipping with aSAH has good discrimination and calibration, which can provide reference for medical staff to identify high-risk patients at an early stage and take preventive intervention measures.

Liver cancer imposes a substantial global disease burden.Hepatocellular carcinoma(HCC),as the primary pathological type of primary liver cancer,accounts for approximately 90%of all cases.As a minimally invasive treatment,thermal ablation causes minimal impact on liver function and trauma,serving as the first-line treatment option for early-stage HCC patients unsuit-able for surgical resection.However,clinical data indicate that 5-year recurrence rate of HCC pa-tients after thermal ablation treatment is as high as 50%~70%,and incomplete ablation remains a core factor leading to recurrence.Therefore,exploring and optimizing complete ablation strategies has become a critical direction for improving the efficacy of thermal ablation in HCC and enhanc-ing long-term survival rates of patients.This paper systematically reviews the current applications of thermal ablation in HCC treatment and focuses on discussing key technologies and strategies for achieving complete ablation,with the aim of providing theoretical foundations and technical refer-ences for improving the complete ablation rate of thermal ablation in clinical practice and formu-lating personalized diagnosis and treatment plans.
