Objective: To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school. Methods: From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention. Results: After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05). Conclusion The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.

Objective To explore the value of the minimum intensity projection(minIP)images generated by post-processing of susceptibility weighted imaging(SWI)and corrected phase image(CPI)in evaluating the asymmetrical prominent veins sign(APVS)in acute ischemic stroke.Methods A retrospective analysis was conducted on 86 patients with acute ischemic stroke.Group A underwent conventional SWI reconstruction to generate minIP images,while group B used CPI for re-reconstruction to produce minIP images.Both groups used the same scanning method but different post-processing techniques to generate two sets of images,with each group consisted of 86 patients.Two deputy chief physicians of imaging diagnostics scored subjectively with a double-blind 5-point method to compare the ability of the two groups to display APVS and analyze the display rate of APVS.Results The subjective scores of group B were significantly higher than those of group A,with a statistically significant difference(P<0.05).The display rates of APVS in groups A and B were 67.44%and 73.26%respectively.Group B had a higher display rate of APVS below the tentorium cerebelli than above it.Conclusion The minIP images generated by CPI post-processing can achieve the effects similar to phase difference enhanced imaging(PADRE),and is superior to SWI reconstruction method in displaying APVS.It can be used as a supplementary post-processing method when acute stroke shows poor APVS,which has practical clinical application value and can provide more imaging basis for clinical practice.

Objective:To explore the current status of orthopedic nurses' health science popularization information generation capacity and training needs in Beijing.Methods:This study was a cross-sectional survey. Convenience sampling was used to select 818 orthopedic nurses from 54 hospitals (48 Class Ⅲ hospitals and 6 ClassⅡ hospitals) in Beijing in April 2024 for the study. General Information Questionnaire, Self-assessment Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity, and Training Needs Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity were used to survey the study participants. Multiple linear regression was used to analyze the factors influencing orthopedic nurses' health science popularization information generation capacity. A total of 818 questionnaires were distributed and 781 valid questionnaires were recovered, with a valid recovery rate of 95.48% (781/818) .Results:The 781 orthopedic nurses had a total score of [49.00 (42.00, 57.00) ] on the Self-assessment Scale for Orthopedic Nurses' Health Science Popularization Information Generation Capacity. Multiple linear regression analysis showed that years of working experience, health status, intention to participate in health science popularization, stage of health science popularization behavior, and frequency of participation in health science popularization training were the factors influencing orthopedic nurses' health science popularization information generation capacity ( P<0.05), which explained 17.30% of the total variation. Beijing orthopedic nurses had training needs in five areas of assessing audience needs, assessing message risk, revising and improving messages, generating messages, and pretesting messages. Conclusions:The Beijing orthopedic nurses' health science popularization information generation capacity is at a medium and high level, but there is still much room for improvement. It is recommended to pay attention to the physical and mental health of orthopedic nurses, improve the work commitment, and build a long-term incentive mechanism to stimulate the enthusiasm of orthopedic nurses in health science popularization. Medical institutions or specialty societies should actively formulate training programs, build training platforms, and gradually perfect the orthopedic nurses' health science popularization training system in order to comprehensively enhance the health science popularization information generation capacity and help China's great health.

Intracranial seminoma is a rare malignant tumor originating from the germ cells,usually occurring in the pineal gland or pituitary gland.In June 2020,the Department of Endocrinology at the First Affiliated Hospital of Army Military Medical University admitted a 20-year-old male patient with an intracranial germ cell tumor and spinal metastases.The patient presented with headache,dizziness,and visual impairment.Enhanced magnetic resonance imaging(MRI)of the head indicated thickening of the pituitary stalk.After multidisciplinary consultation,the patient underwent endonasal transsphenoidal resection of the tumor,with the pathological diagnosis confirming germ cell tumor.The patient received regular radiotherapy postoperatively.One year later,the tumor recurred and metastasized,leading to a second surgery for tumor resection in the thoracic spinal canal,followed by continued chemotherapy.The patient's clinical symptoms,such as headache and visual disturbances,improved,but he continued to experience panhypopituitarism and required long-term hormone replacement therapy.Early diagnosis of intracranial germ cell tumors is challenging,and they are prone to metastasis and highly sensitive to radiotherapy and chemotherapy.Early diagnosis and multidisciplinary comprehensive treatment can help improve the quality of life and prognosis for patients.

Primary liver cancer(PLC)is a common malignant tumor in China.It ranks second in the cause of tumor mortality and it is a serious threat to the lives and health of people.Transcatheter arterial chemoembolization(TACE)is the preferred treatment for patients with HCC who cannot be surgically cured,which is of great significance for prolonging the patient's life.However,the incidence of nausea and vomiting after TACE is very high,which is an important reason for the decline of patient treatment compliance,which seriously affects the quality of life and the effect of interventional therapy.This paper reviews the domestic and abroad literature concerning the nausea and vomiting in patients after TACE,focusing on the clinical features of nausea and vomiting,the risk factors and the assessment tools,so as to provide a scientific basis for clinical early identification and effective intervention of nausea and vomiting after TACE.(J Intervent Radiol,2024,33:565-570)

Objective:To investigate the diagnostic value of non-high-density lipoprotein cholesterol (non-HDL-C),ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C), and triglyceride glucose index (TyG) on metabolic syndrome (MS) in adult women.Methods:This was a cross-sectional study. A total of 24 410 adult women who received health examination in health management center of the Affiliated Hospital of Southwest Medical University were selected from January 2019 to December 2021 as subjects. The subjects′ basic information, physical examination results, and laboratory examination data were collected retrospectively. The relationship between non-HDL-C, TG/HDL-C, TyG, and MS in adult women were examined using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) were calculated to evaluate the diagnostic value of each indicator for MS in adult women.Results:Among 24 410 adult females, 800 (3.3%) were found to have MS. After adjusting for age, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, blood uric acid, history of hypertension, history of diabetes, fatty liver, non HDL-C ( OR=1.608), TG/HDL-C ( OR=1.311), TyG ( OR=13.288) were all risk factors for MS in adult women. non-HDL-C, TG/HDL-C, and TyG, as well as their combined AUC of ROC, were 0.795 (95% CI: 0.742-0.776), 0.909 (95% CI: 0.902-0.917), 0.942 (95% CI: 0.937-0.948), and 0.944 (95% CI: 0.937-0.950), respectively. TyG had the highest diagnostic value for MS in adult women among the three indicators, the optimal cutoff value for TyG was 8.237, with a sensitivity of 93.5% and a specificity of 85.5%. Conclusion:non-HDL-C, TG/HDL-C, TyG, as well as their combination, all demonstrate good diagnostic value for MS in adult women.

Phytoremediation plays an important role in the treatment of heavy metal pollution in soil. In order to elucidate the mechanism of salicylic acid (SA) on copper absorption, seedlings from Xuzhou (with strong Cu-tolerance) and Weifang Helianthus tuberosus cultivars (with weak Cu-tolerance) were selected for pot culture experiments. 1 mmol/L SA was sprayed upon 300 mg/kg soil copper stress, and the photosynthesis, leaf antioxidant system, several essential mineral nutrients and the changes of root upon copper stress were analyzed to explore the mechanism of copper resistance. The results showed that Pn, Tr, Gs and Ci upon copper stress decreased significantly compared to the control group. Meanwhile, chlorophyll a, chlorophyll b and carotenoid decreased with significant increase in initial fluorescence (F₀), maximum photochemical quantum yield of PSⅡ (Fv/Fm), electron transfer rate (ETR) and photochemical quenching coefficient (qP) content all decreased. The ascorbic acid (AsA) content was decreased, the glutathione (GSH) value was increased, the superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activity in the leaves were decreased, and the peroxidase (POD) activity was significantly increased. SA increased the Cu content in the ground and root system, and weakened the nutrient uptake capacity of K, Ca, Mg, and Zn in the root stem and leaves. Spray of exogenous SA can maintain the opening of leaf stomata, improve the adverse effect of copper on photosynthetic pigment and PSⅡ reaction center. Mediating the SOD and APX activity started the AsA-GSH cycle process, effectively regulated the antioxidant enzyme system in chrysanthemum taro, significantly reduced the copper content of all parts of the plant, and improved the ion exchange capacity in the body. External SA increased the content of the negative electric group on the root by changing the proportion of components in the root, promoted the absorption of mineral nutrient elements and the accumulation of osmoregulatory substances, strengthened the fixation effect of the root on metal copper, and avoided its massive accumulation in the H. tuberosus body, so as to alleviate the inhibitory effect of copper on plant growth. The study revealed the physiological regulation of SA upon copper stress, and provided a theoretical basis for planting H. tuberosus to repair soil copper pollution.
