Objective: To understand the association of physical exercise willingness and insomnia with depressive symptoms among college students, so as to provide reference for improving depressive symptoms of college students. Methods: From October 2022 to April 2023, cluster sampling was used to recruit 11 101 college students from four colleges in Anhui Province. The questionnaire survey was conducted to investigate the willingness to engage in physical exercise, insomnia and depressive symptoms of college students. The multivariate Logistic regression model was used to analyze the association of physical exercise willingness and insomnia with depressive symptoms of college students. Results: The prevalence of depressive symptoms among college students was 9.24%. Multivariate Logistic regression analysis showed that college students who were passive participants/non participants in physical activity, or who experienced insomnia, had a higher likelihood of depressive symptoms compared to those who were active participants or did not experience insomnia ( OR =1.84, 2.07, 4.02, all P <0.01). College students who were passive participants or non participants in physical activity and concurrently experienced insomnia had a higher risk of depressive symptoms compared with those who were active participants or did not experience insomnia ( OR =1.87-8.39, all P <0.01). Gender stratified analysis showed that the combined effect of passive physical exercise and insomnia increased the risk of depressive symptoms in both male ( OR = 1.81 -9.87) and female college students ( OR =1.67-7.39) (all P <0.05). Conclusions Both physical exercise willingness and insomnia are associated with depressive symptoms in college students. In order to improve the depressive symptoms of college students, it is necessary to improve the enthusiasm of physical exercise and strengthen the education of sleep health awareness.

Abstract In the context of frequent public health events, effective school health education is an important measure to improve students health literacy and public health system of China.

Using the method of liberature riview paper interprets the curriculum of National Health Education Standards in the U.S. and provides a mirror for China. Health Education standards in the U.S. are characterized by their academic quality, standardized framework, assessment program, equity principles, and other components. A mirror for China includes promoting the construction of the standards based health education curriculum, developing the skills based health education curriculum system, and constructing a performancebased comprehensive evaluation system.

Objective:To explore the application effect of nursing intervention based on the information-motivation-behavioral skills (IMB) model in perioperative nursing of children undergoing concealed penis phalloplasty.Methods:Using the convenient sampling method, a total of 86 children who were admitted to and underwent concealed penis phalloplasty in Jiaxing Maternity and Child Health Care Hospital were selected as the research objects from January 2022 to January 2023. They were randomly divided into the observation group and the control group, with 43 cases in each group. The control group was treated with routine nursing mode, and the observation group was treated with IMB model nursing intervention based on routine nursing. The heart rate (HR) and mean arterial pressure (MAP) levels of children in the two groups were recorded at five time points, such as after preoperative visit (T 0), when leaving the preparation room period (T 1), before anesthesia induction (T 2), when leaving the anesthesia recovery room (T 3) and 24 h postoperative follow-up (T 4). The children were evaluated using Children's Emotional Adjustment Scale Preschool Version (CEAS-P), Modified Yale Preoperative Anxiety Scale (m-YPAS), the Induction Compliance Checklist (ICC) and Pediatric Anesthesia Emergence Delirium (PAED) . Results:After intervention, the CEAS-P scores in the observation group were higher than those in the control group, while the m-YPAS, ICC and PAED scores were lower than those in the control group, and the differences were statistically significant (all P<0.01). There were statistically significant differences in HR and MAP levels of children undergoing concealed penis phalloplasty between the two groups at different time points ( P<0.01). HR and MAP levels at T 0, T 1, T 2, T 3 and T 4 in observation group were lower than those in control group, and the differences were statistically significant (all P<0.05). There was statistically significant differences in the interaction between nursing intervention and HR and MAP over time ( P<0.01) . Conclusions:Nursing intervention based on the IMB model can effectively relieve the psychological anxiety of children with concealed penis phalloplasty in perioperative period and improve surgical safety.

Objective To investigate the effect of agomelatine on the clinical efficacy in elderly patients with acute cerebral infarction(ACI)and comorbid anxiety-depression disorders by regu-lating serum neurotransmitters and nerve cytokines.Methods A total of 160 elderly ACI patients with anxiety and depression symptoms admitted in Pingxiang Second People's Hospital from June 2020 to December 2023 were enrolled in this study.All of them received thrombolysis or interven-tional therapy,and then were randomly divided into control and observation groups,with 80 patients in each group.The control group received conventional psychological intervention,while the observation group was given additional oral administration of agomelatine.Cognitive function,neurological function,neurotransmitters and neuronal cytokines,anxiety and depression scores,sleep quality,quality of life,daily activity ability and adverse reactions were compared between the two groups.Results After intervention,Mini Mental State Examination(MMSE)scores,levels of neuropeptide Y(NPY),5-hydroxytryptamine(5-HT),norepinephrine(NE),dopamine and brain-derived neurotrophic factor(BDNF),36-item Brief Health Questionnaire(SF-36)score,and Bar-thel index scale score were significantly higher in both 2 groups when compared with above indicators before the intervention(P＜0.01).And the MMSE score,NPY,5-HT,NE,dopamine and BDNF levels,SF-36 score and Barthel index scale score were obviously higher in the observa-tion group than the control group(P＜0.01).Both groups obtained notably lower NIHSS score,S100 calcium binding protein B(S100B)and myelin basic protein(MBP)levels,Hamilton Anxiety Rating Scale(HAMA)score,and Hamilton Depression Rating Scale 17(H AMD-17)score and Pittsburgh Sleep Quality Index(PSQI)score after intervention(P＜0.01).And the NIHSS score,S100B and MBP levels,HAMA score,HAMD-17 score,and PSQI score were statistically lower in the observation group than the control group(P＜0.01).During the treatment process,no signifi-cant difference was observed in the incidence of total adverse reactions between the two groups(3.75％vs 6.25％,x2=0.526,P=0.468).Conclusion When agomelatine tablets are indicated for ACI patients with concomitant anxiety-depression disorders,they can effectively rehabilitate cog-nitive function,enhance neurological function,improve sleep quality and quality of life,optimize activities of daily living,eliminate negative emotions,and correct the expression of neurotransmit-ters and neurotrophic factors.

OBJECTIVE: To explore the genetic basis of a patient with clinically suspected Loeys-Dietz syndrome (LDS). METHODS: A child who had presented at Beijing Anzhen Hospital in September 2018 was selected as the study subject. Clinical data and family history of the patient were collected, along with peripheral blood samples of the proband and his parents. Whole exome sequencing (WES) was carried out through next-generation sequencing. RESULTS: Candidate variants were searched through bioinformatic analysis focusing on genes associated with hereditary aortic aneurysms. Candidate variant was verified by Sanger sequencing. The patient was found to have cardiovascular abnormalities including early-onset aortic dilatation and coarctation, and LDS syndrome was suspected. WES revealed that he has harbored a heterozygous c.1526G>T missense variant of the TGFBR2 gene. The same variant was not found in either parent and was predicted as likely pathogenic (PM1+PM2_Supporting+ PM6+PP3+PP4) based on the guidelines from the American College for Medical Genetics and Genomics (ACMG). CONCLUSION The TGFBR2 c.1526G>T variant probably underlay the LDS in this patient and was unreported previously in China. Above finding has enriched the mutational spectrum of the TGFBR2 gene associated with the LDS and provided a basis for the genetic counseling for the patient.

Neuroinflammation is a key contributor to the pathogenic cascades induced by hypoxic-ischemic (HI) insult in the neonatal brain. AD-16 is a novel anti-inflammatory compound, recently found to exert potent inhibition of the lipopolysaccharide-induced production of pro-inflammatory and neurotoxic mediators. In this study, we evaluated the effect of AD-16 on primary astrocytes and neurons under oxygen-glucose deprivation (OGD) in vitro and in mice with neonatal HI brain injury in vivo. We demonstrated that AD-16 protected against OGD-induced astrocytic and neuronal cell injury. Single dose post-treatment with AD-16 (1 mg/kg) improved the neurobehavioral outcome and reduced the infarct volume with a therapeutic window of up to 6 h. Chronic administration reduced the mortality rate and preserved whole-brain morphology following neonatal HI. The in vitro and in vivo effects suggest that AD-16 offers promising therapeutic efficacy in attenuating the progression of HI brain injury and protecting against the associated mortality and morbidity.

Objective:To study the association between apparent temperature (AT) and the incidence of hand,foot, and mouth disease (HFMD) and its spatial heterogeneity in 46 cities in Guangdong, Anhui and Jilin provinces, and provide scientific evidence for the early warning of HFMD.Methods:The data of HFMD incidence and meteorological factors from 2009 to 2018 in Guangdong province, 2009 to 2015 in Anhui province, and 2013 to 2018 in Jilin province were collected. Distributed lag non-linear models were constructed to investigate the association between AT and the incidence of HFMD in 46 cities from three provinces in China. Meta-analysis was used to pool the city-specific estimates, and Meta-regression was applied to analyze the factors that may cause spatial heterogeneity.Results:The relationship between daily AT and the incidence of HFMD in 46 cities appeared nonlinear. The association in Guangdong was similar to that in Jilin, and the risk of HFMD increased with the increase of AT. While the risk of HFMD in Anhui first increased with the increase of AT, and peaked at 18.1 ℃ and then went down. AT on different levels showed different lag impacts and the higher AT showed greater and longer lag impact. The spatial heterogeneity of associations may have been caused by latitude, longitude, average temperature, and average sunshine hours.Conclusions:AT is a comprehensive index to evaluate the association between temperature, relative humidity and wind speed and the incidence of HFMD. Higher AT may increase the risk of HFMD. The AT and HFMD relationship across spatial heterogeneity varies depending on geographic location and meteorological conditions.

Objective:To analyze the molecular characteristics of dengue virus (DENV) strains circulating in Shantou city in 2018 and 2019 for elucidating the reasons causing strikingly different dengue fever epidemics during the two years and understanding the transmission characteristics and routes of DENV, and to provide reference for the prevention and control of dengue fever.Methods:Detection of viral nucleic acid contents and amplification and sequencing of E gene were carried out on 872 samples positive for DENV acid in 2018 and 2019. Phylogenetic trees were constructed based on the E gene sequences to analyze the homology of DENV strains. The sources and transmission routes of the strains were also analyzed. Results:A total of 99 sequences of DENV E gene were acquired, including 68 DENV-1 sequences and 31 DENV-2 sequences. The cases of dengue fever were sporadic in 2018. Phylogenetic tree showed the strains isolated in 2018 were from multi-sources and closely related to those found in Guangzhou city and Southeast Asia area. Dengue fever outbreaks occurred in 2019 and most of the prevalent strains were from a single source, which was speculated to be Cambodia. Conclusions:Dengue fever in Shantou city was mainly caused by imported strains of the same year rather than by local strains in previous years. DENV strains in Shantou might be traced back to Southeast Asia area and transmitted to Shantou through many routes.

Objective: To evaluate the exported risk of novel coronavirus pneumonia (NCP) from Hubei Province and the imported risk in various provinces across China. Methods: Data of reported NCP cases and Baidu Migration Indexin all provinces of the country as of February 14, 2020 were collected. The correlation analysis between cumulative number of reported cases and the migration index from Hubei was performed, and the imported risks from Hubei to different provinces across China were further evaluated. Results: A total of 49 970 confirmed cases were reported nationwide, of which 37 884 were in Hubei Province. The average daily migration index from Hubei to other provinces was 312.09, Wuhan and other cities in Hubei were 117.95 and 194.16, respectively. The cumulative NCP cases of provinces was positively correlated with the migration index derived from Hubei province, also in Wuhan and other cities in Hubei, with correlation coefficients of 0.84, 0.84, and 0.81. In linear model, population migration from Hubei Province, Wuhan and other cities in Hubei account for 71.2%, 70.1%, and 66.3% of the variation, respectively. The period of high exported risk from Hubei occurred before January 27, of which the risks before January 23 mainly came from Wuhan, and then mainly from other cities in Hubei. Hunan Province, Henan Province and Guangdong Province ranked the top three in terms of cumulative imported risk (the cumulative risk indices were 58.61, 54.75 and 49.62 respectively). Conclusion The epidemic in each province was mainly caused by the importation of Hubei Province. Taking measures such as restricting the migration of population in Hubei Province and strengthening quarantine measures for immigrants from Hubei Province may greatly reduce the risk of continued spread of the epidemic.

Objective:To investigate the risk factors of dysplasia in patients with ulcerative colitis (UC) in China.Methods:From March 1st, 2012 to December 30th, 2013, a total of 154 UC patients were prospectively enrolled from the following 11 hospitals, Xijing Hospital of Digestive Diseases, Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Peking Union Medical College Hospital, Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Nanfang Hospital affiliated to Southern Medical University, China-Japan Friendship Hospital, The Second Hospital of Hebei Medical University, West China Hospital affiliated to Sichuan University, The Seventh Medical Center of PLA General Hospital, Zhongshan Hospital affiliated to Xiamen University, and the First Affiliated Hospital of Anhui Medical University. The patients were followed up till December 1st, 2017. All the UC patients underwent colon endoscopy and histopathological evaluation. T test and Chi-square test were used for statistical analysis. Cox proportional risk model was used for identifying the risk factors of dysplasia in UC patients. Results:Finally, 133 UC patients were enrolled, the age was (50.0±11.9) years, the diagnosis age was (35.5±11.6) years, the course of disease was (14.5±6.7) years, and the number of endoscopic examinations was (3.4±1.6) times. A total of 21 patients were detected with dysplasia. No patients were detected with colorectal cancer. The results of univariate analysis revealed that the diagnosis age (hazard ratio ( HR)=1.05, 95% confidence interval ( CI) 1.01 to 1.10, P=0.009) and extensive colitis ( HR=2.92, 95% CI 0.97 to 8.79, P=0.057) were factors with statistically significant difference. The results of multivariate analysis revealed that the old age at diagnosis ( HR=1.06, 95% CI 1.02 to 1.11, P=0.003) and extensive colitis ( HR=3.68, 95% CI 1.21 to 11.19, P=0.022) were independent risk factors of dysplasia in UC patients. The cumulative incidence of dysplasia of UC patients with extensive colitis was higher than that of patients with left-sided colitis (24.3%, 17/70 vs. 6.3%, 4/63), and the difference was statistically significant ( χ2=8.023, P=0.005). Conclusions:Extensive colitis and older age at diagnosis are two independent risk factors of dysplasia in UC patients of our country. The cancer monitoring should be strengthened in UC patients with long course of disease and extensive colitis.
