AIM: To investigate the comorbidity status of myopia and depressive symptoms among middle school students, identify key influencing factors, and establish a prediction model, thereby providing empirical evidence for the comprehensive intervention of these two conditions.METHODS: Students from 3 middle schools in Feidong county were recruited between 2022 and 2024. Myopia was defined as uncorrected visual acuity ≤5.0 with spherical equivalent refraction <-0.50 diopters(D). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale(CES-D), with a score ≥16 indicating the presence of depressive symptoms. A database was established and data were entered using EpiData software. Pearson's Chi-square test and multivariate Logistic regression analysis were performed to identify influencing factors and screen variables with R statistical software(version 4.5.2). Finally, a Stacking ensemble prediction model was constructed using Python3.13 software. RESULTS: The study included 2 476 students, consisting of 1 380 males and 1 096 females. The overall detection rate of myopia-depressive symptom comorbidity among the studied students was 14.54%. Univariate analysis showed that variables were significantly associated with the comorbidity, including family structure, grade level, sugar-sweetened beverage intake, exercise frequency, school bullying, and parental physical or verbal abuse(all P<0.05). Multivariate Logistic regression analysis identified the following risk factors: higher grade levels(8th grade: OR=1.9143, 95%CI: 1.1096-3.3024; 9th grade: OR=1.7884, 95%CI: 1.0506-3.0444; 11th grade: OR=2.1847, 95%CI: 1.1980-3.9840; 12th grade: OR=3.4606, 95%CI: 1.8250-6.5621), daily consumption of sugar-sweetened beverages more than once(OR=3.1383, 95%CI: 1.7112-5.7560), low frequency of moderate-to-vigorous exercise on weekends and holidays(mostly achievable: OR=3.3115, 95%CI: 1.009-10.8685), alcohol consumption(OR=4.4021, 95%CI: 2.7383-7.0766), daily sedentary time exceeding 10 h(OR=1.8594, 95%CI: 1.2141-2.8476), lack of puberty education(OR=3.0098, 95%CI: 2.0659-4.3848), and exposure to parental physical or verbal abuse(OR=2.4050, 95%CI: 1.1484-5.0364). Protective factors included no experience of school bullying(OR=0.0055, 95%CI: 0.0002-0.1602), no history of severe injury(OR=0.3118, 95%CI: 0.1823-0.5332), outdoor activities during class breaks(OR=0.1672, 95%CI: 0.0752-0.3719), and moderate after-school homework duration(2-3 h per day: OR=0.4802, 95%CI: 0.2620-0.8801). The constructed Stacking prediction model demonstrated good discriminative ability, with an area under the receiver operating characteristic curve(AUC)of 0.855, a sensitivity of 81.5%, and a specificity of 74.0%. Key predictive factors included alcohol consumption status, location of recess activities, unhealthy lifestyle composite index(interaction term between sedentary duration and sugar-sweetened beverage intake frequency), academic stress index(interaction term between sedentary duration and homework duration), and after-school homework duration.CONCLUSION: The comorbidity of myopia and depression among middle school students is jointly influenced by multiple factors such as lifestyle, academic pressure, and family/campus environment. It is advocated to implement a three-level intervention system that includes restricting the sale of sugar-sweetened beverages, conducting psychological screening for sedentary students, and carrying out family-school-medical collaborative management of drinking behaviors. This model can be applied to school health screening and the early identification of high-risk groups in community adolescent health management. It is suitable for middle school students in regions with similar economic levels, but not applicable to students receiving special education or those with severe organic diseases.

This paper summarizes Professor LIU Shangyi's clinical experience in treating acute mastitis based on the "membrane collaterals" theory. It is considered that constraint and stagnation of the membrane collaterrals is the primary pathogenic factor， with damp， heat， phlegm， and stasis being the secondary manifestations. If untreated， the condition can progress to heat toxin injuring the membrane. In treatment， the emphasis is diffusing and unblocking membrane collaterals， unblocking breast and relieving constraint. The clinical course of the disease can be divided into three stages including the early stage with mild constraint heat， the middle stage with escalating toxic heat， and the later stage with a decline of pathogens but deficiency of healthy qi. In correspondence， self-made Tongru Formula （通乳方） for diffusing membrane and venting constraint， self-made Toumo Jiedu Formula （透膜解毒方） for unblocking membrane and relieving toxin， and Tuoli Xiaodu Powder （托里消毒散） with modifications for restoring membrane and rectifying healthy qi should be used， respectively.

This research study focuses on addressing the limitations of current neuropathic pain(NP)treatments by developing a novel dual-target modulator,E0199,targeting both Nav1.7,Nay1.8,and Nay1.9 and Kv7 channels,a crucial regulator in controlling NP symptoms.The objective of the study was to synthesize a compound capable of modulating these channels to alleviate NP.Through an experimental design involving both in vitro and in vivo methods,E0199 was tested for its efficacy on ion channels and its therapeutic potential in a chronic constriction injury(CCI)mouse model.The results demonstrated that E0199 significantly inhibited Nav1.7,Nav1.8,and Nav1.9 channels with a particularly low half maximal inhibitory concentration(ICs0)for Nay1.9 by promoting sodium channel inactivation,and also effectively increased Kv7.2/73,Kv7.2,and Kv7.5 channels,excluding Kv7.1 by promoting potassium channel acti-vation.This dual action significantly reduced the excitability of dorsal root ganglion neurons and alle-viated pain hypersensitivity in mice at low doses,indicating a potent analgesic effect without affecting heart and skeletal muscle ion channels critically.The safety of E0199 was supported by neurobehavioral evaluations.Conclusively,E0199 represents a ground-breaking approach in NP treatment,showcasing the potential of dual-target small-molecule compounds in providing a more effective and safe thera-peutic option for NP.This study introduces a promising direction for the future development of NP therapeutics.

Objective To evaluate the efficacy and safety of polyethylene glycol electrolyte powder(PEG)combined with linaclotide(Lin)for bowel preparation in elderly constipated patients before colonoscopy.Methods In this prospective,randomized controlled trial,90 elderly patients with constipation undergoing colonoscopy were recruited at our hospital from June 2022 to December 2023.Participants were randomly assigned to three groups(n=30 each):PEG-3L alone,PEG-3L+Lin,and PEG-2L+Lin.Primary outcome was Boston Bowel Preparation Scale(BBPS)score and secondary outcomes included adverse event rates,colonoscopy completion rate,withdrawal time,and polyp detection rate.Statistical analysis was performed using independent t-tests and chi-square tests.Results The PEG-3L+Lin group achieved significantly higher BBPS scores than both PEG-3L alone and PEG-2L+Lin groups did(both P<0.001).The PEG-2L+Lin group also outperformed the PEG-3L alone group in cleansing efficacy(90.0%vs.76.7%,P=0.008).The PEG-2L+Lin group demonstrated the best tolerability and lowest adverse event rate,the PEG-3L group had the longest withdrawal time(P<0.05),but the three groups showed no significant difference in polyp detection rates.Conclusion PEG combined with linaclotide significantly improves bowel cleansing in elderly constipated patients.PEG-2L+Lin regimen provides optimal balance between efficacy,safety,and tolerability,making it a preferable choice for this population.

Objective To compare the predictive effectiveness of the Glasgow coma scale(GCS),GCS-pupils scale(GCS-P),Glasgow-Pittsburgh coma scale(GPCS),full outline of unresponsiveness scale(FOUR),and coma recovery scale-revised(CRS-R)in forecasting the prognosis of severe stroke patients.Methods A prospective,consecutive cohort of severe stroke patients admitted to the Department of Neurology,First Medical Center of Chinese PLA General Hospital from September 2021 to April 2024 was enrolled.Demographic and clinical data were collected,including age,sex,length of hospital stay,diagnosis(severe ischemic stroke,severe cerebral hemorrhage,aneurysmal subarachnoid hemorrhage),medical history(hypertension,diabetes,coronary artery disease),smoking and drinking habits,vital signs upon admission(temperature,pulse,respiration,blood pressure),neurological examination findings(including speech and brainstem reflexes)at admission,head imaging results(CT,MRI)within 24 h of admission to assess the presence of brain herniation,and whether intubation occurred within 24 h of admission.Patients underwent GCS,GCS-P,GPCS,FOUR,and CRS-R scoring within 8h of admission.Telephone follow-up was conducted at 6 months post-stroke to assess outcomes using the modified Rankin scale(mRS),with mRS scores of 0-2 classified as the good prognosis group and 3-6 as the poor prognosis group.The receiver operating characteristic(ROC)curve was used to assess the prognostic prediction value of the five scales for poor outcomes at 6 months.The area under the ROC curve(AUC)was calculated,and pairwise comparisons of AUC were performed using the Delong test.Results A total of 179 severe stroke patients were enrolled,including 116 males and 63 females.The group consisted of 132 patients with severe ischemic stroke,30 with severe intracerebral hemorrhage,and 17 with aneurysmal subarachnoid hemorrhage.At 6months,126patients had a poor prognosis and 53 had a good prognosis.(1)There were statistically significant differences in age,temperature,pulse,history of coronary artery disease,smoking and drinking habits,presence of speech impairment,abnormal brainstem reflexes,brain herniation,intubation within 24 h of admission,and GCS,GCS-P,GPCS,FOUR,and CRS-R scores between the poor and good prognosis groups(all P＜0.05).(2)ROC analysis revealed that the AUC(95％CI)for predicting poor outcomes at 6 months in severe stroke patients for GCS,GCS-P,GPCS,FOUR,and CRS-R were 0.808(0.742-0.863),0.815(0.750-0.869),0.828(0.765-0.880),0.841(0.780-0.892),and 0.831(0.768-0.883),respectively.Sensitivities were 76.98％,78.57％,82.54％,84.13％,and 82.54％,and specificities were 73.58％,73.58％,67.92％,71.70％,and 73.58％,respectively.The FOUR had the highest AUC,with an optimal cutoff value of 13.(3)Pairwise comparisons of AUC showed a statistically significant difference between the FOUR and GCS(the difference value of AUC is 0.034,95％CI 0.004-0.064,Z=2.194,P=0.028),but no significant differences were observed between other scales(all P＞0.05).Conclusion Compared to GCS,GCS-P,GPCS,and CRS-R,FOUR may provide more valuable prognostic information for severe stroke patients.

Based on the concept of strategic purchasing,it explores the underlying logic of medical insurance payment for hospital weight management services,including enhancing the cost-effectiveness of health investment,motivating hospitals to improve the quality and efficiency of weight management services,and promoting the supply-side reform of weight management services.By drawing on international experience in medical insurance payment for weight management services and analyzing the current practices of Chinese medical insurance systems,it is found China faces challenges in promoting hospital weight management services,such as incoordination between weight management policy advocacy and medical insurance funding,conflicting DRG grouping schemes,and inadequate insurance coverage.To address these issues,it proposes strategies including:improve the top-level design of medical insurance payment for hospital weight management services,give full play to the incentive role of medical insurance payment on hospitals and individuals,build a diversified medical insurance support system for weight management services,optimize the practice path of medical insurance payment for hospital weight management services,and help promote the Healthy China strategy.

Objective:To identify the clinical characteristics and prognosis of patients with hematological disease and neutropenic sepsis in the hematological intensive care unit (HCU).Methods:A retrospective analysis was conducted on patients with hematological disease and sepsis who admitted to HCU, the First Affiliated Hospital of Harbin Medical University from October 2017 to October 2024, to examine the primary therapeutic options, prognosis, cause of death, and infectious features of sepsis.Results:A total of 245 septic patients were included in the study, comprising 88 cases in the neutropenic sepsis group (neutropenic group) and 157 cases in the non-neutropenic sepsis group (non-neutropenic group). Acute leukemia was more prevalent in the neutropenic group [55.68% (49/88) ]. At the time of admission to the HCU, the neutropenic group exhibited unstable vital signs, lower blood cell counts, higher inflammatory markers, elevated Sequential Organ Failure Assessment (SOFA) scores, increased creatinine levels (120.00 μmol/L vs 77.10 μmol/L, P<0.01), higher total bilirubin levels (24.70 μmol/L vs 17.90 μmol/L, P<0.01), and significantly elevated B-type natriuretic peptide levels (567.90 ng/L vs 134.50 ng/L, P<0.01) compared with the non-neutropenic group. Furthermore, septic shock was more common in the neutropenic group [53.40% (47/88) vs 36.94% (58/157), P<0.05]. The mortality rate was also higher in the neutropenic group [46.59% (41/88) ] compared with the non-neutropenic group [32.48% (51/157) ] ( P<0.05), with septic shock accounting for the majority of deaths [70.73% (29/41) ]. Infections caused by gram-negative bacteria [55.68% (49/88) vs 36.30% (57/157), P<0.01] and fungi [14.77% (13/88) vs 6.36% (10/157), P<0.05] were more common in the neutropenic group. However, lung infections were significantly less frequent in the neutropenic group ( P<0.01). Kaplan-Meier survival analysis revealed a substantially worse 28-day overall survival rate for the neutropenic group compared with the non-neutropenic group ( P<0.05) . Conclusion:Patients with hematological diseases and neutropenic sepsis presented with more severe clinical conditions, a higher likelihood of organ failure and septic shock, and significantly increased mortality compared with patients with non-neutropenic sepsis.

Objective:To analyze the epidemiological characteristics and spatiotemporal distribution of hepatitis C in Henan province from 2012 to 2022.Methods:The case report data on hepatitis C from counties and districts in Henan between 2012 and 2022 were collected. The distribution characteristics were analyzed by descriptive epidemiological methods, and GeoDa1.2 software was used to perform spatial autocorrelation analysis. The spatiotemporal epidemiological analysis was conducted using SaTScan 10.1 software.Results:A total of 274 485 hepatitis C cases were reported in Henan from 2012 to 2022. The reported annual average incidence rate was 25.84/100 000 and showed an overall downward trend from 2012 to 2022 ( Z=-4.05, P<0.001). More cases were reported in women. The cases were mainly aged 40-69 years and farmers. Spatial autocorrelation analysis showed that the reported cases of hepatitis C present spatial clustering during 2012—2022, and the areas with high incidence were mainly distributed in counties or districts of Zhengzhou, Zhumadian, Xuchang, Zhoukou, and Nanyang. One class I clustering area was detected by spatiotemporal scanning, which mainly covered Xuchang, Pingdingshan and the surrounding counties ( LLR=16 117.73, RR=1.81, P<0.001). Conclusion:The reported cases of hepatitis C in Henan Province show an overall downward trend from 2012 to 2022 and present spatiotemporal clustering. The seasonal regularity of the hepatitis C epidemic is not obvious. People aged 40-69 years old and farmers are the key population for prevention and control.

Objective:This meta-analysis compares the postoperative outcomes of the double-flap technique (DFT) versus esophagogastrostomy (EG), jejunal interposition (JI), double-tract reconstruction (DTR), and gastric tube anastomosis (GTA) following proximal gastrectomy for gastric cancer.Methods:Prospective and retrospective studies published from database inception until June 2025 were retrieved from PubMed, Embase, Web of Science, Scopus, CNKI, and Wanfang databases. Studies reporting at least one predefined outcome with extractable data were included. Outcomes of interest consisted of incidence of gastroesophageal reflux, overall postoperative complications, anastomotic leakage, anastomotic stenosis, and digestive reconstruction time. Two investigators independently performed literature screening, data extraction, and quality assessment. Randomized controlled trials (RCTs) were evaluated with the Cochrane ROB 2.0 tool, retrospective cohort studies with the Newcastle-Ottawa Scale (NOS), and single-arm studies with the JBI critical appraisal tool. Dichotomous outcomes were pooled using risk ratios (RRs), and continuous variables were summarized with standardized mean differences (SMDs), using fixed- or random-effects models based on I2 statistics. Publication bias was assessed via funnel plots and Egger's test.Results:A total of 55 studies published between 2007 and 2025 were included, comprising 5 RCTs and 50 retrospective studies. Among 4,380 patients, 732 underwent EG, 454 GTA, 1,480 DTR, 468 JI, and 1,246 DFT. Quality assessment indicated that all except six retrospective cohort studies (rated as moderate quality) were of high quality or had low risk of bias. Among the five reconstruction methods, DFT showed the lowest incidence of gastroesophageal reflux (6.6%, 82/1,246) and overall postoperative complications (11.6%, 144/1,246). JI had the lowest rate of anastomotic leakage (1.3%, 6/468), followed by DFT (1.4%, 18/1,246), and DTR had the lowest rate of anastomotic stenosis (2.4%, 36/1,480), followed by DFT (7.5%, 94/1,246). DFT required the longest operative time for reconstruction ([141.2 ± 597.6] minutes), and DTR required the shortest ([50.1 ± 39.0] minutes). Compared to EG, DFT was associated with a significantly lower risk of gastroesophageal reflux (RR=0.13 ,95%CI: 0.03-0.55, P = 0.01), and no significant differences were observed in overall complications (RR=0.98, 95%CI: 0.55-1.74, P = 0.93), anastomotic leakage (RR = 0.81, 95%CI: 0.04-18.43, P = 0.90), or anastomotic stenosis (RR = 0.75, 95%CI: 0.09-6.39, P = 0.79). Compared to JI, DFT showed no significant differences in gastroesophageal reflux (RR = 0.36, 95%CI: 0.10-1.25, P=0.11), overall complications (RR=2.06, 95%CI: 0.30-14.11, P=0.46), anastomotic leakage (RR=2.05, 95%CI: 0.26-16.18, P=0.49), or anastomotic stenosis (RR=0.83, 95%CI: 0.10-7.17, P=0.87). Similarly, compared to DTR, DFT had a lower risk of overall complications (RR=0.70, 95%CI: 0.50-0.98, P=0.04) but a longer reconstruction time (SMD: 2.55, 95%CI: 0.31-4.79, P=0.03). No significant differences were found in gastroesophageal reflux (RR = 0.68, 95%CI: 0.35-1.30, P=0.24), anastomotic leakage (RR=0.59, 95%CI: 0.16-2.17, P=0.43), or anastomotic stenosis (RR=2.44 , 95%CI: 0.44-13.64, P=0.31). Compared to GTA, DFT was associated with a significantly lower risk of gastroesophageal reflux (RR = 0.53, 95%CI: 0.33-0.88, P=0.01), but again there were no significant differences in overall complications (RR = 0.69, 95%CI: 0.41-1.16, P=0.16), anastomotic leakage (RR = 0.25, 95%CI: 0.03-2.14, P=0.21), or anastomotic stenosis (RR=0.65, 95%CI: 0.24-1.76, P=0.40). No significant publication bias was detected in the analysis (Egger's test P>0.05). Conclusions:Among the five common anastomotic methods after proximal gastrectomy, DFT demonstrates superior anti-reflux efficacy, outperforming EG and GTA in particular in preventing gastroesophageal reflux. DFT also exhibits a lower overall complication risk compared with DTR but maintains anastomotic safety comparable with that of the other techniques.

Objective To evaluate the efficacy and safety of amoxicillin-clavulanate(10∶1)for injection in the treatment of community-acquired pneumonia(CAP)in adult patients.Methods Eligible patients were randomized to receive amoxicillin-clavulanate(10∶1)2.2 g or ampicillin-sulbactam(2∶1)3.0 g via intravenous infusion q12h or q8h for 7 to 14 days.The primary endpoint was to the clinical efficacy 7-14 days after discontinuation of treatment.The secondary endpoints included microbiological efficacy and safety.Results All enrolled patients(n=324)were included in the full analysis set(FAS),specifically 165 patients receiving amoxicillin sodium-clavulanate potassium(10∶1)and 159 patients receiving ampicillin sodium-sulbactam sodium(2∶1).The clinical cure rate was 78.8％(130/165)for amoxicillin-clavulanate(10∶1)and 77.4％(123/159)for ampicillin-sulbactam 7-14 days after end of treatment(P＞0.05).The clinical cure rate was 87.5％(126/144)for amoxicillin-clavulanate(10∶1)and 87.4％(111/127)for ampicillin-sulbactam(2∶1)in per protocol set(P＞0.05).Therefore,amoxicillin-clavulanate(10∶1)was non-inferior to ampicillin-sulbactam in the primary endpoint in the treatment of CAP in adult patients.The overall bacterial eradication rate was 94.4％(34/36)for amoxicillin-clavulanate(10∶1)and 89.3％(25/28)for ampicillin-sulbactam(P＞0.05).The common study drug-related clinical adverse event were abnormalities of hepatic function in both the amoxicillin-clavulanate(10∶1)group(4.8％,8/165)and ampicillin-sulbactam group(3.1％,5/159)(P＞0.05).Conclusions Amoxicillin-clavulanate(10∶1)2.2 g Ⅳ infusion q12h or q8h for 7-14 days was noninferior to ampicillin-sulbactam in terms of clinical and microbiological efficacy in the treatment of CAP in adult patients.The safety of the two dosing regimens was comparable.
