ObjectiveTo improve the quality and service performance of community visual health services in Shanghai, and to establish a set of reasonable and effective evaluation index system for community visual health services. MethodsCentered on the national and Shanghai-based visual health policies and based on the current status and development trends of community visual health service program in Shanghai, the candidate indicators were formed through literature review and expert interviews, firstly. The framework of an evaluation index system was formulated through qualitative research successively, which was further revised and perfected using the Delphi method. Coefficient weights were calculated using the analytic hierarchy process (AHP), culminating in the establishment of the community visual health evaluation index system, lastly. ResultsA total of 22 visual health experts from district-level center for disease control, hospital ophthalmology and leaders in charging of visual health service in community health centers participated in the Delphi questionnaire survey, with a questionnaire recovery rate of 100% and an expert authority coefficient of 0.86, indicating high credibility. After a round of correspondence to experts’ importance ratings and discussions, a comprehensive evaluation index system comprising 3 primary indicators, 12 secondary indicators, and 47 tertiary indicators, along with 5 additional indicators, was finalized. ConclusionAn index system tailored to effective evaluation for community visual health initiatives was drawn up in this study, which can promote the capacity building in community eye health services, facilitating the high-quality development of visual health courses, and enhancing residents’ eye health.

In the field of dental aesthetics,digital aesthetic design plays a crucial role in helping dentists to predict treatment outcomes vis-ually,as well as in enhancing the consistency of knowledge and understanding of aesthetic goals between dentists and patients.It serves as the foundation for achieving ideal aesthetic effects.However,there is no clear standard for this digital process currently in China and abroad.Many dentists lack of systematic understanding of how to carry out digital aesthetic design for treatment.To establish standardized processes for dental aesthetic design and to improve the homogeneity of treatment outcomes,Chinese Society of Digital Dental Industry(CSD-DI)convened domestic experts in related field to compile this consensus.This article elaborates on the key aspects of digital aesthetic data collection,integration steps,and the digital aesthetic design process.It also formulates a decision tree for dental aesthetics at macro level and outlines corresponding workflows for various clinical scenarios,serving as a reference for clinicians.

ObjectiveTo analyze the temporal distribution characteristics of crisis calls and eight major counseling issues to the Shanghai mental health hotline, and to provide recommendations for improving hotline management. MethodsDescriptive statistics were used to analyze 1 106 crisis calls and the calls of eight major counseling issues to the Shanghai mental health hotline across months, time periods and weeks from October 2021 to September 2023, and the chi-square test was used to analyze whether there was any difference in the distribution of 1 106 crisis calls and the calls of eight major counseling issues across months, time periods and weeks. ResultsThere were significant differences in the number of crises calls across different months (χ²=87.816, P<0.05), time periods (χ²=161.848, P<0.05), and weekly distributions (χ²=63.329, P<0.05). The highest number of calls occurred in September, while January had the lowest. The peak call times were between 18:00‒20:00, with the fewest calls occurring between 3:00‒5:00. The day of the week with the highest number of calls was Saturday, while Wednesday had the lowest. Among the different types of counselling issues in crisis calls, the highest number of calls were related to mental disorders, while the fewest calls were related to COVID-19. ConclusionCrisis calls to the Shanghai mental health hotline are concentrated at specific times, indicating that relevant organizations should optimize resource allocation based on this time distribution.

Methamphetamine(METH)is highly addictive and neurotoxic,which causes cognitive and memory dysfunction in abusers.The harm of METH lies not only in its own toxicity,but also in the high physical and mental dependence of drug addicts,often causing mental disorders and violent behavior,bringing great safety risks to society.Non-coding RNA(ncRNA)does not encode proteins and is an important factor in regulating gene expression at the post-transcriptional level.Studies have shown that ncRNA plays an important regulatory role in methamphetamine-induced addiction and neurotoxicity,but the specific mechanism is unclear.This article reviews the current research progress of ncRNA in regulating METH-induced addiction and neurotoxicity to provide a reference for ncRNA as a forensic identification index and potential therapeutic target for METH abusers.

Purpose: Relative energy deficiency in sport (REDs) is a syndrome of physiological and/or psychological functioning experienced by female and male athletes that is caused by exposure to problematic low energy availability. For the prevention and intervention of REDs, awareness of REDs among sports physicians is important, but it is largely unknown. This study aimed to survey the awareness and clinical treatment experience of REDs in sports physicians. Methods: We conducted an online survey to assess awareness of the triad and REDs among sports physicians and members of The Korean Society of Sports Medicine. Results: A total of 69 members (62.2% male, including sports physicians) to this survey. Most participants (84.1%) were aware of the triad compared to fewer with awareness regarding REDs (23.2%). People who knew about the difference between REDs and triad was 33.3%, which was lower than those who did not (66.6%). Only 10.1% of the study subjects had experience treating REDs patients, and the biggest difficulty in treating patients was a lack of information and education (50.7%). It appeared that the most information about REDs was obtained from academic conferences (59.4%). Conclusion This survey found relatively low awareness of REDs among physicians treating athletes and sports professionals. Considering the various negative effects of REDs on athlete health and performance, education and promotion are needed to increase awareness among sports physicians and sports professionals.

Objective To develop a pulmonary rehabilitation training system based on scenario simulation for children with bronchiolitis obliterans,and to explore its application effect.Methods A pulmonary rehabilitation training program for children with bronchiolitis obliterans was constructed,and on the basis of this program,a pul-monary rehabilitation training system based on scenario simulation was developed for children with bronchiolitis obliterans,with real-time monitoring of relevant data.44 children with bronchiolitis obliterans who were hospitalized in the Department of Respiratory Medicine of a tertiary A children's specialized hospital in Hunan Province from January to December 2022 were selected by convenience sampling method,and the subjects were divided into an experimental group and a control group with 22 cases in each group.The experimental group adopted a pulmonary rehabilitation training program based on scenario simulation,and the control group implemented pulmonary rehabili-tation through nurse demonstration and guidance.At pre-intervention,4 weeks,and 12 weeks of intervention,the 2 groups were compared in terms of clinical symptom severity,pulmonary function,adherence to pulmonary rehabilita-tion,and the occurrence of pulmonary rehabilitation-related adverse events.Results There were no shedding cases in the experimental group and a case in the control group,and 22 cases were finally included in the experimental group and 21 cases in the control group.The results of repeated measures ANOVA showed that the comparison of clinical symptom severity and pulmonary function between the 2 groups at different time points was statistically sig-nificant in terms of time,between groups and interaction(P＜0.05).Simple effect analysis showed that after 4 and 12 weeks of intervention,the severity of clinical symptoms in the experimental group was lighter than that in the control group,and the difference was statistically significant(P＜0.001).At 12 weeks of intervention,pulmonary func-tion indexes,such as exertional expiratory volume in the first second,exertional lung volume,and maximum expiratory flow rate,were higher in the experimental group than those in the control group,and the difference was statistically significant(P＜0.001).At 4 and 12 weeks of intervention,the compliance of pulmonary rehabilitation in the experi-mental group was higher than that of the control group,and the difference was statistically significant(P＜0.05).At 12 weeks of intervention,the occurrence of adverse events related to pulmonary rehabilitation in the experimental group was less than that in the control group,and the difference was statistically significant(P=0.026).Conclusion The use of a scenario simulation-based pulmonary rehabilitation training system for children with bronchiolitis obliterans can effectively alleviate the clinical symptoms of children,improve their pulmonary function,increase compliance,and reduce the occurrence of pulmonary rehabilitation-related adverse events.

Objective:To investigate the prevalence of frailty among elders aged ≥60 years in the Beijing community and analyze the risk factors of frailty.Methods:This is a cross-sectional study. A total of 1936 older persons in Baizhifang Community in Beijing were included between May and September 2023. Their frailty was evaluated by Fried Frailty Phenotype Scale. Mini Nutritional Assessment-Short Form (MNA-SF), Short Physical Performance Battery (SPPB), and Geriatric Depression Scale (GDS) were used to evaluate nutritional status, physical function, and depression, respectively. The prevalence and risk factors of frailty among the elderly in the community were analyzed.Results:A total of 168 individuals met the criteria for frailty, and the prevalence of frailty was 8.7%. Compared to the non-frail group, the frail group was predominantly female (71.4% vs 62.2%; χ 2=5.59, P=0.018), older [(72.1±6.6) vs (69.9±6.0) ages; t=-5.25, P<0.001], unmarried (1.8% vs 0.8%; χ 2=8.60, P=0.014), with lower education levels (10.7% vs 3.5%; χ 2=23.38, P<0.001), poorer self-assessed health (22.6% vs 6.5%; χ 2=69.80, P<0.001), lower MNA-SF scores [(12.2±2.2) vs (13.0±1.4) scores; t=6.29, P<0.001], lower SPPB scores [(8.4±1.9) vs (10.2±1.6) scores; t=14.62, P<0.001], higher GDS scores [(4.0±3.8) vs (1.9±2.1) scores; t=-11.48, P<0.001], and worse vision, hearing, and olfactory functions (48.2% vs 34.1%, 36.9% vs 23.0%, 9.5% vs 3.0%; χ 2=13.37, 16.11, 40.58, all P<0.001). They were also more likely to suffer from hypertension (70.8% vs 56.7%; χ 2=12.52, P<0.001), diabetes (42.3% vs 29.4%; χ 2=12.06, P<0.001), osteoarthritis (46.4% vs 30.3%; χ 2=18.39, P<0.001) and stroke (19.0% vs 13.3%; χ 2=4.28, P=0.039). Logistic regression analysis showed that frailty was independently associated with nutritional status ( OR=0.8, 95% CI: 0.7-0.9, P<0.001), depressive symptoms ( OR=1.1, 95% CI: 1.1-1.2, P<0.001), olfactory function ( OR=2.1, 95% CI: 1.4-3.0, P<0.001; OR=2.9, 95% CI: 1.4-5.9, P=0.003), and physical function ( OR=0.6, 95% CI: 0.6-0.7, P<0.001) after adjusting for covariates. Conclusions:The prevalence of frailty among elderly people in community is relatively high. Frailty in community elders is associated with physical function, psychological function, nutritional status, and olfactory function decline.

Objective:To analyze mobility limitation condition and its relationship with cognitive function in community-dwelling elderly.Methods:In this cross-sectional study, a total of 1 935 older adults aged≥60 years were recruited from May to September 2023 in Beijing Baizhifang Community Health Service Center and its five subordinate health service stations (Baizhifang Hutong health service station, Nancaiyuan community health service station, Youanmen community health service station, Younei West Street health service station and Shuanghuaili community health service station). The Short Physical Performance Battery (SPPB) was used to assess the mobility capacity of the elderly, and the elderly were divided into two groups with SPPB, the elderly with a SPPB≤9 points were grouped into mobility limitation group (645 cases), and the ones with a SPPB≥10 points were considered with normal mobility capacity (1 290 cases). The cognitive function of the older adults was assessed with the mini-mental state examination; and the gender, age, calf circumference, history of chronic disease, frailty status, cognitive function, nutritional status, depression status, hearing and vision condition of the two groups were compared with χ2 test or Mann-Whitney U non-parametric test. Multiple logistic regression analysis was used to analyze the mobility limitation and its relationship with cognitive function in the older adults. Results:Mobility limitation was found in 33.33% (645/1 935) of community-dwelling older adults. The proportions of advanced age, female, hypertension, diabetes, coronary heart disease, stroke, chronic obstructive pulmonary disease, frailty, depression, cognitive impairment, hearing decline, and vision decline in the mobility limitation group were all significantly higher than those in the normal mobility capacity group (31.32% vs 13.41%, 69.92% vs 59.61%, 65.27% vs 54.03%, 33.80% vs 28.60%, 27.91% vs 19.53%, 17.83% vs 11.47%, 10.54% vs 7.36%, 13.18% vs 2.02%, 18.45% vs 6.59%, 14.73% vs 7.75%, 30.54% vs 20.31%, 45.58% vs 30.39%) (all P<0.05). Advanced age ( OR=2.542, 95% CI: 1.977-3.269), female ( OR=1.736, 95% CI: 1.390-2.167), stroke ( OR=1.426, 95% CI: 1.065-1.911), depression ( OR=2.292, 95% CI: 1.656-3.174), cognitive impairment ( OR=1.601, 95% CI: 1.154-2.220), frailty ( OR=5.199, 95% CI: 3.219-8.397) and vision decline ( OR=1.405, 95% CI: 1.124-1.756) were all positively correlated with the mobility limitation in the community-dwelling older adults (all P<0.05). Conclusion:The older adults in the community have a higher risk of mobility limitation, mobility limitation is a positive correlation factor of cognitive impairment.

Objective:To discuss the protective effect of sodium butyrate(NaB)on acute liver injury in the mice induced by lipopolysaccharide(LPS)combined with D-galactosamine(D-Gal),and to clarify its mechanism.Methods:Thirty male Kunming mice were randomly divided into control group,model group,and NaB group,and there were 10 mice in each group.The mice in NaB group were given 200 mg·kg-1·d-1 NaB,while the mice in control group and model group were given an equal volume of sterile water.The mice in model group and NaB group were intraperitoneally injected with 20 μg·kg-1 LPS and 600 mg·kg-1 D-Gal to induce the acute liver injury models.The body weights and liver weights of the mice in various groups were detcted,and the liver index was calculated.HE staining was used to observe the pathomorphology of liver tissue of the mice in various groups;kits were used to detect the activities of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in serum,and the activities of total superoxide dismutase(T-SOD)and catalase(CAT),and the levels of malondialdehyde(MDA)in liver tissue of the mice in various groups;Western blotting method was used to detect the expression levels of nuclear factor E2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)proteins in liver tissue of the mice in various groups.Results:There were no significant differences in body weights of the mice among various groups(P>0.05).Compared with control group,the liver index of the mice in model group was significantly increased(P<0.01).Compared with model group,the liver index of the mice in NaB group was significantly decreased(P<0.01).The HE staining results showed that the liver tissue of the mice in control group exhibited normal structure,with clear boundaries of hepatocytes,consistent size,radially arranged around the central vein,and the nucleus located in the center of the cells;in model group,the arrangement of hepatocytes was disordered,the cells were swollen,there were multiple foci of hepatocellular necrosis,inflammatory cell infiltration,and hemorrhage;compared with model group,the cells in NaB group showed improved hepatocellular structure and reduced inflammatory infiltration.Compared with control group,the activities of ALT and AST in serum of the mice in model group were significantly increased(P<0.01);compared with model group,the activities of ALT and AST in serum of the mice in NaB group were significantly decreased(P<0.05 or P<0.01).Compared with control group,the activities of T-SOD and CAT in liver tissue of the mice in model group were significantly decreased(P<0.01),and the level of MDA was significantly increased(P<0.01);compared with model group,the activities of T-SOD and CAT in liver tissue of the mice in NaB group were significantly increased(P<0.05 or P<0.01),and the level of MDA was significantly decreased(P<0.01).The Western blotting results showed that compared with control group,the expression levels of Nrf2 and HO-1 proteins in liver tissue of the mice in model group were significantly decreased(P<0.05);compared with model group,the expression levels of Nrf2 and HO-1 proteins in liver tissue of the mice in NaB group were significantly increased(P<0.01).Conclusion:NaB has a protective effect on LPS/D-Gal induced acute liver injury in the mice,and its mechanism may be related to the upregulation of the expressions of Nrf2 and HO-1 proteins and the increas of the activity of oxidant enzyme in liver tissue by NaB,thereby reduces the liver oxidative stress level of liver.

Seizures are a prevalent clinical manifestation during the neonatal period.The majority of neonatal seizures are transient symptoms caused by acute lesions，but in a few cases they are developmental epileptic encephalopathy with neonatal onset.Continuous video-EEG monitoring is the gold standard for diagnosing seizures in newborns,and complex seizures require comprehensive judgment using multi-channel monitoring such as synchronized EMG,blood oxygen,ECG,and respiratory monitoring.In 2021,the International League Against Epilepsy (ILAE) published the updated guidelines for the classification of neonatal seizures,proposing that neonatal seizures cannot be diagnosed if there is only clinical seizure without EEG evidence.Instead,they should be categorized into two types based on the presence of clinical movements and the characteristics of EEG changes during the seizure: electroclinical seizures and electrical seizures.Electroclinical seizures are categorized into motor seizures,non-motor seizures,sequential seizures,and unclassified seizures based on the symptoms exhibited during an attack.In 2023,the ILAE developed evidence-based recommendations for the management of antiseizure medications,discussed the treatment of neonatal seizures based on the latest evidence and emphasized the importance of video EEG in the treatment of neonatal seizures.Phenobarbital remains the first-line antiseizure medication,with phenytoin,levetiracetam,midazolam,or lidocaine as second-line agents.Pyridoxine should be considered for the treatment of neonatal seizures when first- and second-line drugs are ineffective.
