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 views of adolescents with asthma on factors affecting disease self-management, so as to provide a basis for improving self-management of asthma children, and propose improvement suggestions.Methods:This study was a descriptive qualitative study. From February to June 2023, 10 to 17 year old children with asthma were recruited at the Asthma Clinic of the Children's Hospital affiliated to Capital Institute of Pediatrics through purposive sampling. One-on-one semi-structured interviews were conducted around self-management and its related factors, and the thematic analysis was used to analyse interview materials.Results:A total of 17 adolescents with asthma, aged (13.00±2.03) years, with a course of disease of (5.00±2.85) years, were included. The interview materials included two aspects, namely facilitators and barriers of self-management. The facilitators were coded into three themes and seven sub-themes, including the individual management awareness of children with asthma (sense of responsibility, compliance awareness), social support (parental care and compensation, teacher and classmate support, patient interaction), and health education (health guidance from doctors and nurses, school health propaganda). Barriers were encoded into three themes and six sub-themes, including disease cognition (demand competition, importance), social environment (interpersonal interaction, physical environment), and healthcare services (accessibility of medical services, school related medical resources) .Conclusions:The self-management of adolescents with asthma is affected by multiple factors. Individual management awareness, social support, and health education can promote self-management in children with asthma, while unfavorable factors in disease cognition, social environment, and healthcare services can hinder self-management in children with asthma. Medical and nursing staff should develop and implement empowerment plans for self-management of asthma children, by mobilizing multi-channel medical resources, providing multi-dimensional full process empowerment, and helping asthma children build a diverse interpersonal support network system, in order to promote effective health management transition for adolescents with asthma.

Objective:To investigate the clinical and electrophysiological characteristics of patients with amyotrophic lateral sclerosis (ALS) with positive repetitive nerve stimulation (RNS) test results on the accessory nerve and negative needle electromyography (EMG) test results on the sternocleidomastoid with the goal to enrich the knowledge of disease progression in patients with ALS.Methods:The clinical data of 612 patients diagnosed with ALS at the Neurology Department of the First Medical Center, Chinese PLA General Hospital from June 2016 to August 2022 were collected. In total, 267 cases had undergone EMG tests on the sternocleidomastoid following a positive 3 Hz RNS test result on the accessory nerve, who were selected as the study subjects. The differences in clinical indicators were compared between RNS (+)/EMG (-) group and RNS (+)/EMG (+) group. A binomial distribution model with multiple variables was built to quantitatively analyze the major factors and their effects.Results:At the initial visit, 15.8% of patients with ALS were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid, accounting for 36.3% of RNS (+) patients. The decremental range of the 3 Hz RNS test delivered to the accessory nerve in these patients [-14% (-19%, -12%)] was lower than that in patients with RNS (+)/EMG (+) [-17% (-23%, -13%)] ( P<0.05), while the ratio of upper limb onset (64.9%) and non-definite diagnosis (28.9%) were higher [54.7% and 13.5% for patients with RNS (+)/EMG (+), P<0.05]. Furthermore, the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score [40 (37, 42)], body mass index (BMI) [23.8 (22.0, 25.4) kg/m 2] and forced vital capacity (FVC) [92.8% (76.6%, 103.8%)] were higher in patients with RNS(+)/EMG(+) ( P<0.05). The multivariate model suggested that, in patients with RNS (+)/EMG (-), the ratio of upper limb onset to lower limb onset was 1.04, while that of upper limb onset to bulbar onset was 2.02, and that of lower limb onset to bulbar onset was 1.94. The ratio of non-definite ALS to definite ALS was 1.13. The ALSFRS-R score, BMI, and FVC had a protective contribution to the electrophysiological function of the motor neurons. The ratio of the effect size of the ALSFRS-R or BMI to that of FVC was 3.37 and 1.14, respectively. Conclusions:Patients with ALS that were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid had a smaller decremental range of the compound muscle action potential amplitude, and a higher proportion of upper limb onset and non-definite ALS. A higher ALSFRS-R score, BMI, and FVC have a protective effect to the electrophysiological function of motor neurons. The effect size of the ALSFRS-R score is the largest, followed by BMI and FVC.

Objective To investigate the mental resilience of disabled elderly with suicidal ideation in nursing homes and analyze its related factors.Methods By using convenience sampling and the Chinese version of the Beck scale for suicide ideation,a total of 119 disabled elderly with suicidal ideation were screened from 8 nursing homes in Chongqing from May to October 2022.Then they were investigated with the general information questionnaire,the Memorial University of Newfoundland scale of happiness,the 10-item connor-davidson resilience scale and the hospital depression scale.Results The average score of resilience of disabled elderly with suicidal ideation was(1.58±0.70)points,which was at a lower level.There were statistically significant differences in the mental resilience of disabled elderly with suicidal ideation in terms of the nature of the nursing homes,the degree of disability and education,the length of stay,the frequency of communication with relatives and participation in collective activities.The mental resilience of disabled elderly with suicidal ideation was negatively correlated with depressive symptoms(r1=-0.631,P＜0.001),and positively correlated with subjective well-being(r2=0.652,P＜0.001).Among disabled elderly with suicidal ideation,the degree of education and subjective well-being positively predicted mental resilience,while depressive symptoms negatively predicted mental resilience(adjusted R2=0.521,P＜O.001).Conclusion The mental resilience level of disabled elderly with suicidal ideation in nursing homes is lower.Nursing homes should focus on improving the mental resilience of disabled elderly with lower educational level,lower subjective well-being and higher depression symptoms,so as to improve their adaptability.

Objective:To explore the relevancy between the uridine diphosphate-glucuronylgly-cosyltransferase 1A1 (UGT1A1) gene mutation and the phenotype of indirect hyperbilirubinemia in children.Methods:Sixteen cases with indirect hyperbilirubinemia who visited the Department of Gastroenterology, Children's Hospital of Nanjing Medical University from July 2013 to November 2019 were retrospectively analyzed and were divided into Gilbert syndrome (GS), Crigler-Najjar syndrome type II (CNS-II), and indirect hyperbilirubinemia groups unexplained by UGT1A1 gene mutations. The differences in gene mutation site information and general clinical data were compared. The association between gene mutation spectrum and bilirubin level was explored by t-test analysis.Results:Ten of the sixteen cases with indirect hyperbilirubinemia had GS, three had CNS-II, and three had indirect hyperbilirubinemia unexplained by UGT1A1 gene mutations. A total of six mutation types were detected, of which c.211G?>?A accounted for 37.5% (6/16), c.1456T?>?G accounted for 62.5% (10/16), and TATA accounted for 37.5% (6/16), respectively. Compared with the GS group, the CNS group had early disease onset incidence, high serum total bilirubin ( t ?=?5.539, P ??0.05) and age of onset ( t ?=?0.3611, P ?>?0.05) between the two groups. There was no significant correlation between the number of UGT1A1 gene mutations and serum bilirubin levels. Children with c.1456T?>?G homozygous mutations had the highest serum bilirubin levels. Conclusion:The common pathogenic variants of the UGT1A1 gene sequence are c.1456T?>?G, c.211G?>?A, and TATA, indicating that these site mutations are related to the occurrence of indirect hyperbilirubinemia and have important guiding significance for the etiological analysis of indirect hyperbilirubinemia in children.

Objective:To analyze the clinical characteristics and all-cause mortality influencing factors of patients with Keshan disease.Methods:Clinical data of patients with Keshan disease from Keshan disease areas in Sichuan Province and Yunnan Province were collected and retrospectively analyzed for clinical characteristics and survival status during regular follow-up. According to the survival status of patients, the survey subjects were divided into a survival group and a death group. All-cause mortality (referring to the death caused by various reasons throughout the follow-up period) was used as the study endpoint. Kaplan-Meier (K-M) survival curve analysis and log-rank χ 2 test were performed, univariate and multivariate Cox regression analysis were used for all-cause mortality factor analysis. Results:A total of 176 patients with Keshan disease were collected, including 92 cases in Sichuan Province and 84 cases in Yunnan Province. Among all the patients, there were 105 males, accounting for 59.66%, and 71 females, accounting for 40.34%. The age was (53.89 ± 13.19) years old. Thirty-five cases died from all causes, with a mortality rate of 19.89%. There were significant differences in age ( t = 2.09, P = 0.038), New York Heart Association (NYHA) cardiac function grading (χ 2 = 14.62, P < 0.001) and ventricular premature contraction (χ 2 = 6.82, P = 0.009) between the survival group and the death group. K-M survival curve analysis showed that patients with Keshan disease complicated by premature ventricular contraction and high NYHA cardiac function grading (Ⅲ and Ⅳ) had higher all-cause mortality (log-rank χ 2 = 8.72, 22.49, P < 0.05). Univariate Cox regression analysis showed that NYHA cardiac function grading and ventricular premature contraction ( HR = 3.09, 2.71, P < 0.05) were predictive influencing factors for all-cause mortality in patients with Keshan disease. Multivariate Cox regression analysis showed that NYHA cardiac function grading ( HR = 6.57, P = 0.002) and ventricular premature contraction ( HR = 2.98, P = 0.050) were independent factors for all-cause mortality in patients with Keshan disease. Conclusions:Among 176 patients with Keshan disease, the number of patients with poor cardiac function (NYHA cardiac function grading Ⅲ and Ⅳ) and arrhythmia is high. NYHA cardiac function grading and ventricular premature contractions are independent influencing factors for all-cause mortality in patients with Keshan disease.

Objective To observe the clinical and CT features of neonatal adrenal cystic neuroblastoma(CNB).Methods Eight newborns with adrenal CNB confirmed by surgical pathology were retrospectively analyzed.The clinical data were recorded,and the plain and enhancement abdominal CT manifestations were observed.Results Among 8 cases,6(6/8,75.00％)were detected with prenatal ultrasound,while 2(2/8,25.00％)were detected after birth with ultrasound,all with single adrenal grand lesion,located half in left and half in right adrenal gland(each 4/8,50.00％).The maximum diameter of CNB lesion was 2.3-6.1 cm,with the median maximum diameter of 4.5 cm.CT showed all 8 lesions(8/8,100％)presented as single localized adrenal grand thick-walled cystic lesion,among which 3(3/8,37.50％)with uniform density within the cysts,3(3/8,37.50％)with internal septum within the cysts,1(1/8,12.50％)with slight floating debris and the rest 1(1/8,12.50％)with both internal septum and floating debris in the cyst.No calcification,cross the midline nor surround blood vessels were observed.Seven(7/8,87.50％)lesions had clear while 1(1/8,12.50％)had unclear boundaries,all mildly compressed surrounding structures.The capsule wall and internal septum of the cysts slightly enhanced after enhancement.Multiple liver metastases occurred in 2 cases.Conclusion Most neonatal adrenal CNB were detected before delivery,which mainly presented as thick-walled cystic mass with clear boundary,accompanied by septa and floating debris,and the cystic wall and septa slightly enhanced after enhancement,and liver metastasis might occur.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Dementia in traditional Chinese medicine （TCM） mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course， and the drugs that can reverse the disease course remain to be developed. Therefore， early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors， cognitive functions， and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases， being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore， early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy， and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage， and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia， the apathetic behaviors of dementia animal models， the behaviors of patients with apathy， and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.
