Objective: To analyze the trajectory of dietary behaviors among middle school students in Jiading District, Shanghai, from 2021 to 2023, and longitudinally verify their association with anxiety and depression symptoms, aiming to provide scientific evidence for promoting the mental health of adolescents. Methods: The data were sourced from the National Monitoring and Intervention Project on Common Diseases and Health Impact Factors of students in Jiading District, Shanghai. A total of 1 217 middle school students who participated in at least two surveys from 2021 to 2023 were selected as the research objects, and group-based trajectory model was constructed to identify their dietary behavior scores trajectories. Modified Poisson regression was used to investigate the impact of dietary behavior scores trajectories on anxiety and depression, while Logistic regression was employed to explore the association between trajectories and changes in depression score levels. Results: The dietary behavior scores trajectories of middle school students were divided into three groups: Persistent Healthy Dietary Behavior (9.5%), Persistent Relatively Unhealthy Dietary Behavior (85.0%), and Persistent Very Unhealthy Dietary Behavior (5.5%). Students who perceived their academic performance as poor and whose parents had a cultural level of high school or below had a significantly lower proportion in the Persistent Healthy Dietary Behavior group compared to students with other characteristics ( χ 2=12.87, 8.69, 6.50, P <0.05). Compared with the Persistent Healthy Dietary Behavior group, the risk of anxiety symptoms in middle school students in the Persistent Very Unhealthy Dietary Behavior group was significantly increased ( aRR=3.04, 95%CI =1.15-8.02); Persistent Relatively Unhealthy Dietary Behavior and Persistent Very Unhealthy Dietary Behavior increased the risk of depressive symptoms ( aRR = 1.80 , 2.45, respectively), and were positively correlated with the increase in depression scores ( aOR =1.70, 2.24) ( P <0.05). Conclusions The dietary behavior of middle school students have not changed significantly in the past three years, with persistent unhealthy dietary behavior being the most common. Unhealthy dietary behaviors are positively correlated with the risk of anxiety and depressive symptoms and an increase in depression scores.

ObjectiveTo observe the effectiveness and safety of modified Taohong Siwu Decoction （桃红四物汤） for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome. MethodsA total of 120 patients of chronic heart failure with lower limb deep vein thrombosis in chronic stage of blood stasis syndrome were randomly divided into 60 cases each in control group and observation group. Both groups were given basic treatment of western medicine， and the observation group was additionally given modified Taohong Siwu Decoction （桃红四物汤） for oral administration， one dose per day. The treatment course for both groups lasted for 4 weeks. The total effective rate and the incidence of adverse reactions were compared between the two groups after treatment. Cardiac function indexes including left ventricular ejection fraction （LVEF）， and left ventricular end-systolic internal diameter （LVESd）， left ventricular end-diastolic internal diameter （LVEDd）， serological indexes including N-terminal natriuretic natriuretic peptide precursor （NT-proBNP）， high sensitivity C-reactive protein （hs-CRP） and vascular endothelial growth factor （VEGF）， score of traditional Chinese medicine （TCM） symptom including chest pain， swelling of the affected limb， fixed tenderness， and bruising， haemodynamics indicators including high cut whole blood viscosity， low cut whole blood viscosity， and erythrocyte pressure， and coagulation indices including activated partial thromboplastin time （APTT）， plasminogen time （PT）， and fibrinogen （FIB） levels were compared before and after treatment. ResultsDuring the study， 3 cases were excluded and 2 cases lost follow-up in the observation group， while 2 cases were excluded and 3 cases lost follow-up in the control group. A total of 110 patients completed the trial， 55 cases in each of the two groups. The total effective rate in the observation group was 92.73% （51/55）， which was significantly higher than that of the control group， 78.18% （43/55， P＜0.05）. Compared within group before treatment， LVEF， APTT and PT levels increased， LVESd， LVEDd， NT-proBNP， hs-CRP， VEGF， high cut whole blood viscosity， low cut whole blood viscosity， erythrocyte pressure volume and FIB levels decreased， chest pain， swelling of the affected limbs， stationary pressure pain and bruising score decreased in both groups after treatment， and the improvement of all above indexes was better in the observation group than that in control group （P＜0.05 or P＜0.01）. The incidence of adverse reactions was 7.27% （4/55） in the observation group and 21.82% （12/55） in the control group， and the incidence of adverse reactions in the observation group was significantly lower than that in the control group （P＜0.05）. ConclusionModified Taohong Siwu Decoction （桃红四物汤） as adjuvant treatment for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome showed better clinical effectiveness when compared with western basic treatment， which can improve the clinical symptoms， cardiac function， haemodynamics， and coagulation， with good safety.

Objective: To investigate the current status of refractive errors and insufficient hyperopia reserve in preschool children aged 3-6 years in Hefei and to analyze influencing factors, so as to provide a scientific basis for formulating targeted myopia prevention policies and comprehensive interventions. Methods: In May 2022, a stratified cluster random sampling method was used to select 897 preschool children from 8 kindergartens across four districts (Baohe, Yaohai, Shushan, and Economic and Technological Development Zone) in Hefei, and Children’s Visual Health related Behavior Assessment Scale was used to collect personal information and environmental factors. Pre and post cycloplegic refraction tests were conducted to assess insufficient hyperopic reserve and refractive development levels. Group comparisons were conducted using 2 test, t-test or analysis of variance. Multivariate regression analysis was performed to identify key factors influencing hyperopic reserve, axial length and spherical equivalent in preschool children. Results: The detection rates of refractive errors among preschool children were 6.8% for hyperopia, 1.6% for myopia, and 11.1% for astigmatism. Notably, the prevalence of myopia was significantly higher in boys (2.3%) than in girls (0.7%) ( χ 2=3.88, P <0.05). Additionally, 8.8% of the children exhibited insufficient hyperopic reserve. The results of multiple regression analysis showed that preschool children with high myopia in the father, high myopia in the mother, longer daily duration of near work, and longer daily electronic product use time had increased risks of axial growth ( β =0.12, 0.09, 0.15, 0.11), SE reduction ( β =-0.10, -0.07, -0.18, -0.13), and insufficient hyperopic reserve ( OR=1.87, 2.22, 1.40, 1.28) (P <0.05). While, preschool children with longer sleep time and daily outdoor activity duration had lower risks of axial growth ( β =-0.11, -0.10 ), SE reduction ( β =0.39, 0.51), and insufficient hyperopia reserve ( OR =0.54, 0.51) in preschool children ( P <0.05). Conclusions The rates of refractive errors and insufficient hyperopia reserve in preschool children in Hefei are relatively low, which are influenced by many factors. Parents, kindergartens and relevant departments should implement early vision monitoring and intervention for preschool children, and cultivate their scientific eye use habits.

Objective: To analyze the epidemiological characteristics and changing trends of non suicidal self injury (NSSI) behaviors among middle school students in Jiading District of Shanghai, from 2015 to 2023, so as to provide a basis for the development of NSSI prevention and control measures among students. Methods: Using a stratified cluster random sampling method, a total of five times for Shanghai Adolescent Health Risk Behavior Surveys were conducted for every two years in Jiading District of Shanghai from 2015 to 2023. A total of 5 231 middle school students from junior high schools and senior high schools were selected for questionnaire surveys. Intergroup comparisons were performed using the x 2 test or the χ 2 trend test, and the JointPoint 5.0 software was used to analyze the changing trends, with the annual percent change (APC) used for evaluation. A binary Logistic regression model was employed to analyze the related factors of NSSI behavior among middle school students. Results: In 2023, the reported NSSI rate among middle school students in Jiading District was 14.2%. The rate was significantly higher among junior high school students (17.1%) than that among senior high school students (11.1%), and higher among females (19.2%) than that among males (10.0%) ( χ 2=10.04, 23.21, both P <0.01). From 2015 to 2023, the overall reported NSSI rate showed an increasing trend, rising from 8.6% in 2015 to 14.2% in 2023 ( χ 2 trend =22.25), with an APC of 6.64% ( t =3.49), and the APC for girls was 9.79 % ( t =3.20) (all P <0.05). Among students reporting NSSI, the proportion experiencing ≥6 episodes increased from 10.8% in 2015 to 19.2% in 2023 ( χ 2 trend =6.57, P <0.05). Multivariate Logistic regression analysis indicated that girls, junior high school students, those with insomnia, depressive emotion and drinkers had higher risks of NSSI, compared to boys, senior high school students, those without insomnia, non depressive emotion students and non drinkers ( OR =1.71, 1.96, 3.44, 4.76, 1.77, all P < 0.05 ). Conclusions The reported rate of NSSI among middle school students in Jiading District of Shanghai, increased annually from 2015 to 2023, and the proportion of repeated NSSI also showed an upward trend. Early intervention measures targeting middle school students, especially junior high school students and females, should be implemented to prevent and control its occurrence and development.

To describe the incidence and mortality of adult head and neck cancer (HNC) in different regions worldwide and their temporal trends.

Objective:To explore the correlation between periodontitis (PD) and chronic kidney disease (CKD) in adults, as well as the potential mechanisms involved.Methods:Data on PD and CKD from the National Health and Nutrition Examination Survey (NHANES) database between 1999 and 2014 were downloaded. Weighted univariate and multivariate logistic regression analyses were conducted to investigate the risk factors associated with PD and CKD, considering demographic and clinical indicators. Using publicly available genome-wide association study (GWAS) summary datasets for CKD and PD as outcome variables, as well as 731 immune cell phenotypes and 91 inflammatory proteins as exposure factors from the OPEN GWAS database, a two-sample Mendelian randomization (TSMR) analysis was performed using the inverse-variance weighted (IVW) method.Results:Seven demographic indicators including gender, age, race, education level, marital status, income, and health are related to the incidence of CKD and PD. Among them, the elderly (≥60 years old), poverty (poverty-income ratio <1.3), divorce or widowhood, and male ratio in the comorbidity group of CKD and PD [67.12% (833/1 241), 36.83% (457/1 241), 34.41% (427/1 241), and 57.78% (717/1 241) respectively] were significantly higher than those in the control group [23.71% (4 179/17 623), 29.17% (5 141/17 623), 18.16% (3 200/17 623), and 48.73% (8 587/17 623) respectively] (all P<0.001). Those with high educational level (university and above) and self-rated excellent health accounted for a relatively small proportion in the comorbidity group [14.10% (175/1 241) and 8.22% (102/1 241) respectively]. The prevalence of PD increased among individuals with abnormal renal function indices, including glomerular filtration rate, urine protein/creatinine ratio, serum creatinine, serum uric acid, and blood urea nitrogen. Univariate logistic regression analysis showed a positive correlation between the incidence of PD and CKD ( OR=2.14, 95 %CI: 1.90-2.42, P<0.001). Multivariate logistic regression analysis also indicated that PD and CKD were potential risk factors for each other (PD for CKD: OR=1.22, 95 %CI: 1.07-1.40, P=0.004; CKD for PD: OR=1.19, 95 %CI: 1.04-1.37, P=0.012). Furthermore, after adjusting the model based on demographic indicators, there was still a significant correlation between PD and CKD ( P=0.010). Mechanistically, the results of the TSMR analysis support the existence of a common risk factor mediated by immune cells between CKD and PD, namely the expression of CD64 on multiple innate immune cells mediates the occurrence of CKD and PD. The absolute count of CD64 + monocytes is associated with an increased risk for both CKD ( HR=1.11) and PD ( HR=1.07), while same tendency showed in the absolute count of CD64 + neutrophils for CKD ( HR=1.22) and PD ( HR=1.23). Conclusions:There is a positive correlation between CKD and PD, particularly moderate to severe PD, and the shared pathogenesis involves CD64 + monocytes in the circulatory system. Targeted interventions focusing on CD64 molecules or monocyte subsets may be beneficial.

Objective To construct a nomogram prediction model for major adverse cardiovascular events(MACE)within 1 year after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS).Methods A retrospective analysis was conducted on 551 patients with diagnosed ACS and undergoing PCI in Department of Cardiovascular Medicine of Air Force Medical Center from 1 January 2020 to 1 April 2022.According to the occurrence of MACE during 1 year of follow-up,they were classified into MACE group(n=176)and non-MACE group(n=375).Risk factors for the occurrence of MACE in elderly ACS patients within 1 year after PCI were analysed using univariate and multivariate logistic regression,a nomogram prediction model was constructed,and the predictive power of the model was assessed using the area under the ROC curve(AUC).Results The MACE group had significantly higher Gensini score,systemic immune-inflammation index,and GRACE score,but obviously lower prognostic nutritional index than the non-MACE group(P＜0.01).Multivariate logistic regression analysis showed that recent smoking(OR=2.222,95％CI:1.361-3.628,P=0.010),hyperlipidaemia(OR=1.881,95％CI:1.145-3.089,P=0.013),prognostic nutritional index(OR=4.645,95％CI:2.788-7.739,P=0.001),LVEF(OR=5.177,95％CI:3.160-8.483,P=0.001),systemic immune-inflammation index(OR=5.396,95％CI:3.179-9.159,P=0.001),and preoperative di-agnosis of non-STEMI(OR=2.829,95％CI:1.356-5.901,P=0.006)or STEMI(OR=3.451,95％CI:1.596-7.463,P=0.002)were independent influencing factors for occurrence of MACE after PCI in elderly ACS patients.ROC curve analysis showed that the AUC value of the nomo-gram model for predicting MACE within 1 year after PCI in elderly ACS patients was 0.888.Con-clusion Our developed nomogram model is simple and practical,and can effectively predict the occurrence of MACE within 1 year after PCI in elderly ACS patients.And external validation should be carried out to ensure its generality.

Objective To investigate the therapeutic efficacy of dandelion extract on intracerebral hemorrhage(ICH)rats and its effect on nuclear factor erythroid 2 related factor 2(Nrf2)/heme oxygenase-1(HO-1)signaling pathway.Methods Stereotaxic intracranial injection of type Ⅳ col-lagenase was used to establish rat ICH model.Then 48 ICH rats were randomly divided into mod-el group,dandelion extract group,Nrf2 inhibitor(ML385)group and dandelion extract+ML385 group,with 12 rats in each group.Another 12 rats served as sham operation group.After treat-ment,neurological deficits was evaluated and scored for all groups of rats.Blood-brain barrier(BBB)function,neuronal apoptotic rate in the hippocampus,serum levels of COX-2,IL-6 and iNOS,cerebral contents of CAT,GSH-Px,ROS and MAD,and protein levels of Nrf2/HO-1 signal pathway were detected.Results Compared with sham operation group,the neurological deficit score,Evans blue exudation,appptotic rate of hippocampal neurons,serum COX-2,IL-6,iNOS levels,brain tissue reactive oxygen species(ROS)and malondialdehyde level in the model group were significantly increased(P＜0.05),and the expression levels of CAT,GSH-Px,Nrf2 and HO-1 proteins were significantly decreased(P＜0.05).Compared with dandelion extract group,combination of dandelion extract and ML385 significantly increased the neurological deficit score(2.54±0.23 vs 1.43±0.19),Evans blue exudation[(22.15±3.61)ng/mg vs(6.54±1.24)ng/mg],apoptotic rate[(31.97±5.26)％vs(3.51±0.94)％],serum COX-2[(5.82±1.16)ng/ml vs(1.34±0.42)ng/ml],IL-6[(1.47±0.31)ng/ml vs(0.43±0.14)ng/ml]and iNOS levels[(59.91±10.36)U/ml vs(13.94±3.78)U/ml],brain tissue ROS[(4.70±0.45)U/kg vs(1.70± 0.51)U/kg]and MDA levels[(3.72±0.52)nmol/mg vs(1.17±0.34)nmol/mg],and decreased expression levels of CAT[(2.54±0.59)U/mg vs(5.68±1.04)U/mg],GSH-Px[(8.01±0.86)U/mg vs(16.97±3.03)U/mg],Nrf2(0.67±0.13 vs 1.07±0.19)and HO-1(0.55±0.07 vs 0.86± 0.10,P＜0.05).Conclusion Dandelion extract can enhance the antioxidant activity in ICH rats by activating Nrf2/HO-1 signaling pathway,prevent the progression of inflammation and oxida-tive stress,inhibit neuronal apoptosis in hippocampus,repair blood-brain barrier function,and thus improve nerve function.

Objective To detect the relative expression level of long non-coding RNA nuclear enriched a-bundant transcript(NEAT)1 in peripheral serum of patients with gastric cancer,and to explore the possibili-ty of its application in the auxiliary diagnosis of gastric cancer.Methods A total of 101 patients with newly diagnosed gastric cancer in Nantong Tumor Hospital from November 2017 to December 2019 were selected as the gastric cancer group,60 patients with benign gastric lesions were selected as the gastric benign lesions group,and 76 healthy people were selected as the control group.The relative expression levels of lncRNA NEAT1,carcinoembryonic antigen(CEA)and carbohydrate antigen 19-9(CA19-9)in serum samples of each group were detected,and the correlation between lncRNA NEAT1 and clinicopathological parameters was ana-lyzed.Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic efficacy of lncRNA NEAT1,CEA and CA19-9 alone or in combination.Results The relative expression levels of lncRNA NEAT1 in serum of gastric cancer group,gastric benign disease group and control group were 2.163(1.357,2.843),1.176(0.677,1.381)and 1.063(0.570,1.308),respectively,and the difference was statistically significant(H=52.467,P＜0.001).The relative expression level of serum lncRNA NEAT1 in gastric cancer patients was not related to gender(P=0.353)and age(P=0.382),but was related to tumor size(P=0.031),TNM stage(P=0.037)and lymph node metastasis(P=0.046).The relative expression level of lncRNA NEAT1 in serum of gastric cancer patients was not correlated with CEA and CA19-9(P＞0.05).The ROC curve showed that the area under the curve and sensitivity of lncRNA NEAT1 in the diagnosis of gastric cancer were higher than those of CEA and CA19-9.The combined diagnosis of the three had the highest diagnostic efficiency.Conclusion The relative expression of lncRNA NEAT1 in peripheral blood of patients with gastric cancer is increased,and it is correlated with some clinicopathological parameters.lncRNA NEAT1 may be a new marker for auxiliary diagnosis of gastric cancer.

Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.
