Objective: To investigate the current prevalence of myopia and the progression of the axial length/corneal radius ratio(AL/CR) among primary school students in Jing an District, Shanghai, and to analyze the value of dynamic AL/CR monitoring and elucidate its longitudinal association with myopia progression, so as to provide evidences for supporting myopia prevention and control interventions. Methods: From 2019 to 2023, by using a stratified cluster random sampling method, 17 624 students from two primary schools in Jing an District, Shanghai were selected for annual vision screenings in five consecutive years. Additionally, a retrospective cohort of 480 eligible first grade students identified in 2019 was followed up until 2023. The analysis focused on the myopia prevalence and the trend in the AL/CR. Differences in screening myopia rates across different student groups from 2019 to 2023 were compared using the Chi square test. The trends in myopia rates were analyzed using the Chi square trend test. The Kruskal-Wallis H test was employed to compare AL/CR and its annual increment across groups. A linear mixed effects model was used to identify factors influencing AL/CR, and a time dependent Cox regression model was developed to predict the risk of myopia onset. Results: From 2019 to 2023, the screening myopia rates were 36.65%, 38.31%, 40.47%, 39.56%, and 39.76% for each respective year. Cohort analyses revealed Grade 5 girls had significantly greater AL/CR increments than boys ( Z =-2.05, P <0.05). Linear mixed models identified baseline AL/CR ( β =1.051, 95% CI =1.012-1.091), grade level ( β =0.040, 95% CI =0.038- 0.042 ), and first year AL/CR increment ( β =0.788, 95% CI =0.733-0.843) as primary determinants (all P <0.01). Boys showed slower AL/CR progression than girls ( β =-0.003, 95% CI =-0.005 to-0.001, P <0.01). The time dependent Cox model demonstrated that both baseline AL/CR ( Z =3.40) and its time varying effect ( Z =10.41) significantly predicted myopia risk(both P <0.01). The effect of AL/CR on myopia risk significantly increased with follow up time, and the growth rate exceeded a linear progression pattern. Conclusions AL/CR progression is primarily driven by baseline values and grade advancement, with slower progression in boys. Dynamic AL/CR monitoring outperforms baseline measurements in predicting myopia progression. Students with rapid AL/CR increments require early intervention.

Objective:To investigate the efficacy of Naikan cognitive therapy(NCT)combined with medica-tion in improving depressive symptoms and sleep quality in patients with chronic schizophrenia.Methods:Patients were included if they met the following criteria:diagnosed with schizophrenia based on ICD-10 criteria,a disease course of ≥2 years,stable condition under maintenance antipsychotic medication,presence of depressive symptoms and sleep quality issues,and no use of antidepressants in the past two months.A total of 64 eligible patients were randomly assigned to the NCT group(n=32)or the mental health education(MEC)group(n=32).The interven-tion lasted 6 days,with 2 patients from each group dropping out.The Beck Depression Inventory-Ⅱ(BDI-Ⅱ)and Pittsburgh Sleep Quality Index(PSQI)were used to assess depressive symptoms and sleep quality.Results:After the intervention,the BDI-Ⅱ score difference(post-treatment score minus pre-treatment score)in the NCT group was significantly lower than that in the MEC group(P＜0.001).Similarly,the PSQI total score difference was also lower in the NCT group compared to the MEC group(P＜0.001).Conclusion:Adding Naikan cognitive therapy to routine medication treatment can effectively improve depressive symptoms and sleep quality in patients with chronic schizophrenia.

Objective:To explore the core dimensions of adolescent anxiety and their relationship with parental rearing styles and perceived social support using network analysis.Methods:A total of 3 712 adolescents were in-vestigated.The Screen for Child Anxiety Related Emotional Disorders,the Short-form Egna Minnenav Barndoms Uppfostran for Chinese,and the Perceived Social Support Scale were used to assess the anxiety levels,parental rea-ring styles,and perceived social support.Network analysis and gender network comparison were conducted using R programming language.Results:The network analysis model showed that generalized anxiety and somatization/pan-ic anticipation had the highest Expected Influence of 1.21 and 1.12,which were the two core dimensions of adoles-cent anxiety levels.The affective warmth in parental rearing styles had a Bridge Expected Influence index of 0.34,making it a bridging node in the network.The network comparison result indicated that there were significant struc-tural gender differences in the adolescent anxiety-parenting style-perceived social support network(P＜0.05),but there was no significant gender difference in global strength(P＞0.05).Conclusion:Interventions targeting adoles-cent anxiety should prioritize generalized anxiety and somatization/panic.Emotional warmth in parenting serves as a bridge connecting adolescent anxiety with perceived levels of social support.

Objective To explore the effect of exercise under cold exposure on hepatic protein ki-nase B(AKT)/forkhead box O1(FoxO1)expression in obese rats.Methods Among rats successfully induced nutritional obesity by high-fat diet,forty were selected and randomly divided into a normal-temperature control group(NC,n=10),a normal-temperature exercise group(NE,n=10),a sus-tained-cold control group(SC,n=10),and a sustained-cold exercise group(SE,n=10).The normal temperature was kept at 25°C±1°C,while the low temperature remained at 4°C±1°C,with 50%to 60%relative humidity.The exercise protocol was every other day at a speed of 25 m/min for 2 sets of 30 min each,with an interval of 10 minutes.After 5 weeks,glucose and insulin tolerance were tested by oral glucose tolerance test(OGTT)and insulin tolerance test insulin tolerance test(ITT).Then,all rats were weighed and sacrificed,then taken blood from the abdominal aorta to sepa-rate serum,followed by detection of serum alanine aminotransferase(ALT)and aspartate aminotransfer-ase(AST)levels using fully automatic biochemical analyzer.Moreover,livers were weighed to calcu-late the liver index.Meanwhile,the mRNA expressions of hepatic AKT,FoxO1 and PEPCK were de-tected using RT-qPCR,while the protein expressions of AKT,phosphorylated protein kinase B(p-AKT),and FoxO1 in the liver were measured using Western blotting.Results(1)The average body weights of the NE,SC and SE groups were significantly lower than the NC group(P<0.01),with that of the SC and SE groups significantly lower than the NE group(P<0.01).(2)Compared with the NC group,the area under the OGTT curve of the SC group decreased(P<0.01).Moreover,the area under the ITT curve of the SE group was significantly lower than the other 3 groups(P<0.01,P<0.01,P<0.05),with that of the NE and SC groups significantly lower than the NC group(P<0.05,P<0.01).(3)The liver indices of the NE,SC and SE groups were all significantly lower than the NC group(P<0.01),while the serum ALT level of the NE group was significantly lower than the NC and SE groups(P<0.05),with that of the SC group significantly lower than the NC group(P<0.01).(4)Compared with the NC group,hepatic AKT mRNA expression increased significantly in the SE group(P<0.05),while the hepatic FoxO1 and PEPCK mRNA expression decreased significantly in the other three groups(P<0.01).(5)Compared with the NC group,the liver AKT protein phosphorylation levels were significantly higher in the other three groups(P<0.05,P<0.05,P<0.01),while the FoxO1 protein expression decreased significantly(P<0.05,P<0.01,P<0.01).(6)Body mass,liver FoxO1,PEPCK mRNA expression,AKT protein phosphorylation level and FoxO1 protein expression level of obese rats were affected by cold exposure,exercise and cold exposure+exercise,and the liver index and serum ALT level were done by exercise and cold exposure+exercise.However,the area un-der the ITT curve and liver AKT mRNA content were impacted by cold exposure and exercise,while that under the OGTT curve was influenced by cold exposure and cold exposure+exercise.Conclu-sion Exercise under cold exposure can activate hepatic AKT/FoxO1 signaling pathway,protect liver function,increase insulin sensitivity,and effectively improve glucose metabolism in obese rats.

Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE: To develop a method for identifying high-risk patients among septic populations requiring mechanical ventilation, and to conduct phenotypic analysis based on this method. METHODS: Data from four sources were utilized: the Medical Information Mart for Intensive Care (MIMIC-IV 2.0, MIMIC-III 1.4), the Philips eICU-Collaborative Research Database 2.0 (eICU-CRD 2.0), and the Anhui Medical University Second Affiliated Hospital dataset. The adult patients in intensive care unit (ICU) who met Sepsis-3 and received invasive mechanical ventilation (IMV) on the first day of first admission were enrolled. The MIMIC-IV dataset with the highest data integrity was divided into a training set and a test set at a 6:1 ratio, while the remaining datasets were served as validation sets. The demographic information, comorbidities, laboratory indicators, commonly used ICU scores, and treatment measures of patients were extracted. Clinical data collected within first day of ICU admission were used to calculate the sequential organ failure assessment (SOFA) score. K-means clustering was applied to cluster SOFA score components, and the sum of squared errors (SSE) and Davies-Bouldin index (DBI) were used to determine the optimal number of disease subtypes. For clustering results, normalized methods were employed to compare baseline characteristics by visualization, and Kaplan-Meier curves were used to analyze clinical outcomes across phenotypes. RESULTS: This study enrolled patients from MIMIC-IV dataset (n = 11 166), MIMIC-III dataset (n = 4 821), eICU-CRD dataset (n = 6 624), and a local dataset (n = 110), with the four datasets showing similar median ages and male proportions exceeding 50%; using 85% of the MIMIC-IV dataset as the training set, 15% as the test set, and the rest dataset as the validation set. K-means clustering based on the six-item SOFA score was performed to determine the optimal number of clusters as 3, and patients were finally classified into three phenotypes. In the training set, compared with the patients with phenotype II and phenotype III, those with phenotype I had the more severe circulatory and respiratory dysfunction, a higher proportion of vasoactive drug usage, more obvious metabolic acidosis and hypoxia, and a higher incidence of congestive heart failure. The patients with phenotype II was dominated by respiratory dysfunction with higher visceral injury. The patients with phenotype III had relatively stable organ function. The above characteristics were consistent in both the test and validation sets. Analysis of infection-related indicators showed that the patients with phenotype I had the highest SOFA score within 7 days after ICU admission, initial decreases and later increases in platelet count (PLT), and higher counts of neutrophils, lymphocytes, and monocytes as compared with those with phenotype II and phenotype III, their blood cultures had a higher positivity rates for Gram-positive bacteria, Gram-negative bacteria and fungi as compared with those with phenotype II and phenotype III. The Kaplan-Meier curve indicated that in the training, test, and validation sets, the 28-day cumulative mortality of patients with phenotype I was significantly higher than that of patients with phenotypes II and phenotype III. CONCLUSIONS Three distinct phenotypes in septic patients receiving IMV based on unsupervised machine learning is derived, among which phenotype I, characterized by cardiorespiratory failure, can be used for the early identification of high-risk patients in this population. Moreover, this population is more prone to bloodstream infections, posing a high risk and having a poor prognosis.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.
