AIM: To investigate the relationship between Apelin and δ-like ligand 4(DLL4)expression levels and clinical stage and efficacy in patients with neovascular glaucoma(NVG).METHODS: A total of 96 NVG patients(96 eyes)who were admitted to our hospital from January 2022 to March 2024(NVG group)and 96 cataract patients(96 eyes)who underwent cataract surgery in our hospital during the same period(control group)were selected. NVG patients were divided into stage Ⅰ group(22 eyes), stage Ⅱ group(47 eyes)and stage Ⅲ group(27 eyes)according to the clinical stage; furthermore, patients were divided into ineffective group(20 eyes)and effective group(76 eyes)according to efficacy. Aqueous humor Apelin and DLL4 levels were detected by enzyme-linked immunosorbent assay. The influencing factors of the efficacy in NVG patients were analyzed by multivariate unconditional Logistic regression analysis, the evaluation efficiency of aqueous humor Apelin and DLL4 levels on the efficacy in NVG patients was analyzed by receiver operating characteristic(ROC)curve.RESULTS: Compared with the control group, aqueous humor Apelin and DLL4 levels in the NVG group were increased(all P<0.001). Aqueous humor Apelin and DLL4 levels in the stage Ⅰ, stage Ⅱ and stage Ⅲ groups increased in turn(all P<0.001). The effective rate of 96 NVG patients was 79.2%(76/96). Compared with the effective group, aqueous humor Apelin and DLL4 levels in the ineffective group increased(all P<0.001). Clinical stage III, high intraocular pressure, high Apelin and DLL4 were independent risk factors for ineffective treatment in NVG patients(all P<0.05). The area under the curve of the combined evaluation of aqueous humor Apelin and DLL4 levels in evaluating the efficacy of NVG patients was 0.874, which was greater than 0.790 and 0.786 of aqueous Apelin and DLL4 levels alone(all P<0.05).CONCLUSION: Aqueous humor Apelin and DLL4 levels in NVG patients increase, which relate to the increase of clinical stage and poor efficacy, and the combination of aqueous humor Apelin and DLL4 levels is more effective in evaluating the efficacy of NVG patients.

Objective To compare the long-term survival of elderly patients with esophageal squamous cell carcinoma (ESCC) treated with surgical versus non-surgical treatment. Methods A retrospective analysis was conducted on the clinical data of elderly patients aged ≥70 years with ESCC who underwent esophagectomy or radiotherapy/chemotherapy at Sichuan Cancer Hospital from January 2009 to September 2017. Patients were divided into a surgical group (S group) and a non-surgical group (NS group) according to the treatment method. The propensity score matching method was used to match the two groups of patients at a ratio of 1∶1, and the survival of the two groups before and after matching was analyzed. Results A total of 726 elderly patients with ESCC were included, including 552 males and 174 females, with 651 patients aged ≥70-80 years and 75 patients aged ≥80-90 years. There were 515 patients in the S group and 211 patients in the NS group. The median follow-up time was 60.8 months, and the median overall survival of the S group was 41.9 months [95%CI (35.2, 48.5)], while that of the NS group was only 24.0 months [95%CI (19.8, 28.3)]. The 1-, 3-, and 5-year overall survival rates of the S group were 84%, 54%, and 40%, respectively, while those of the NS group were 72%, 40%, and 30%, respectively [HR=0.689, 95%CI (0.559, 0.849), P<0.001]. After matching, 138 patients were included in each group, and there was no statistical difference in the overall survival between the two groups [HR=0.871, 95%CI (0.649, 1.167), P=0.352]. Conclusion Compared with conservative treatment, there is no significant difference in the long-term survival of elderly patients aged ≥70 years who undergo esophagectomy for ESCC. Neoadjuvant therapy combined with surgery is still an important choice to potentially improve the survival of elderly patients with ESCC.

Objective: To investigate the spatio-temporal clustering characteristics of influenza in Shaoxing City, Zhejiang Province from 2015 to 2024, so as to provide the basis for formulating influenza prevention and control strategies. Methods: Influenza case data in Shaoxing City from 2015 to 2024 were collected through the Infectious Disease Surveillance Reporting System of the Chinese Disease Prevention and Control Information System. Descriptive epidemiological methods analyses were used to analyze the epidemiological characteristics of influenza. Spatial autocorrelation and spatio-temporal scanning were used to analyze the spatio-temporal clustering characteristics of influenza. Results: A total of 328 759 influenza cases were reported in Shaoxing City from 2015 to 2024, with an average annual reported incidence of 639.90/100 000, which showed an upward trend (AAPC=68.95%, P<0.05). The peak incidence period was from December to February of the following year, with 193 051 cases reported, accounting for 58.72%. There were 165 408 male cases and 163 351 female cases, with a male-to-female ratio of 1.01∶1. Children and adolescents aged 0-<15 years constituted the high-incidence population, while students represented the predominant occupational category, comprising 113 589 cases (34.55%). Keqiao District, Shengzhou City, and Yuecheng District had the top three average annual reported incidence of influenza, at 995.64/100 000, 734.66/100 000, and 687.44/100 000, respectively. Spatial autocorrelation analysis showed that, there were 155 high-high aggregation areas in Shaoxing City from 2015 to 2024, which gradually expanded from the local aggregation in the central part of Shengzhou City to Keqiao District and then spread to Yuecheng District. Spatio-temporal scanning analysis showed that, from November 2023 to February 2024, the strongest spatio-temporal clustering of influenza centered on Keqiao Street in Keqiao District, covering 11 towns (streets) in Yuecheng District and Keqiao District. From 2015 to 2018, the primary-type clustering of influenza was mainly concentrated in Xinchang County and Shengzhou City. After 2019, they gradually shifted to Yuecheng District and Keqiao District, with the main clustering period being from November to February of the following year. Conclusions The incidence of influenza in Shaoxing City from 2015 to 2024 showed an upward trend, with obvious spatio-temporal clustering. The clustering area expanded from Shengzhou City in the central region to Keqiao District and Yuecheng District in the northern region, mainly clustering from November to February of the following year.

Loss-of-function variants of low-density lipoprotein receptor-related protein 5 (LRP5) can lead to reduced bone formation, culminating in diminished bone mass. Our previous study reported transcription factor osterix (SP7)‍-binding sites on the LRP5 promoter and its pivotal role in upregulating LRP5 expression during implant osseointegration. However, the potential role of SP7 in ameliorating LRP5-dependent osteoporosis remained unknown. In this study, we used mice with a conditional knockout (cKO) of LRP5 in mature osteoblasts, which presented decreased osteogenesis. The in vitro experimental results showed that SP7 could promote LRP5 expression, thereby upregulating the osteogenic markers such as alkaline phosphatase (ALP), Runt-related transcription factor 2 (Runx2), and β‍-catenin (P<0.05). For the in vivo experiment, the SP7 overexpression virus was injected into a bone defect model of LRP5 cKO mice, resulting in increased bone mineral density (BMD) (P<0.001) and volumetric density (bone volume (BV)/total volume (TV)) (P<0.001), and decreased trabecular separation (Tb.‍Sp) (P<0.05). These data suggested that SP7 could ameliorate bone defect healing in LRP5 cKO mice. Our study provides new insights into potential therapeutic opportunities for ameliorating LRP5-dependent osteoporosis.

Gut microbial communities are likely remodeled in tandem with accumulated physiological decline during aging, yet there is limited understanding of gut microbiome variation in advanced age. Here, we performed a metagenomics-based enterotype analysis in a geographically homogeneous cohort of 367 enrolled Chinese individuals between the ages of 60 and 94 years, with the goal of characterizing the gut microbiome of elderly individuals and identifying factors linked to enterotype variations. In addition to two adult-like enterotypes dominated by Bacteroides (ET-Bacteroides) and Prevotella (ET-Prevotella), we identified a novel enterotype dominated by Escherichia (ET-Escherichia), whose prevalence increased in advanced age. Our data demonstrated that age explained more of the variance in the gut microbiome than previously identified factors such as type 2 diabetes mellitus (T2DM) or diet. We characterized the distinct taxonomic and functional profiles of ET-Escherichia, and found the strongest cohesion and highest robustness of the microbial co-occurrence network in this enterotype, as well as the lowest species diversity. In addition, we carried out a series of correlation analyses and co-abundance network analyses, which showed that several factors were likely linked to the overabundance of Escherichia members, including advanced age, vegetable intake, and fruit intake. Overall, our data revealed an enterotype variation characterized by Escherichia enrichment in the elderly population. Considering the different age distribution of each enterotype, these findings provide new insights into the changes that occur in the gut microbiome with age and highlight the importance of microbiome-based stratification of elderly individuals.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Objective: To investigate sleep quality among patients with hypertension and diabetes, so as to provide the basis for improving the health of patients with chronic diseases. Methods: From May to August 2022, patients with hypertension and diabetes under the community management in 4 counties and cities (districts) of Shaoxing City, Zhejiang Province were recruited using a multi-stage stratified cluster random sampling method. Demographic information, disease history, smoking, alcohol consumption, physical activity and sleep quality were collected by questionnaire surveys, and blood pressure, fasting blood glucose and glycosylated hemoglobin were collected through physical examination and laboratory testing. The incidence of poor sleep quality symptoms (snoring/asphyxia/suffocation, difficulty falling asleep, night awakening, taking sleeping pills and early morning awakening) in patients with diabetes and hypertension was descriptively analyzed, and sleep quality was evaluated. Results: A total of 1 539 patients with hypertension and diabetes were surveyed, including 715 males (46.46%) and 824 females (53.54%). The patients had a mean age of (68.68±7.62) years. The proportions of night awakening, early morning awakening, snoring/asphyxia/suffocation, difficulty falling asleep and taking sleeping pills were 29.82%, 28.53%, 20.73%, 15.79% and 4.29%, respectively. The proportion of poor sleep quality was 66.54%. Employment status, smoking status, moderate/high intensity physical activity and blood pressure control were related to poor sleep quality (all P<0.05). Conclusion Poor sleep quality is common in patients with hypertension and diabetes, with the main symptoms being night awakening, early morning awakening, difficulty falling asleep and snoring/asphyxia/suffocation.

Objective: To investigate the situation of road traffic injuries (RTIs) among middle school students in Shaoxing City, Zhejiang Province, so as to provide the basis for implementation of interventions against RTIs among students. Methods: From 2021 to 2023, a multi-stage stratified cluster sampling method was used to select 82 junior high school classes and 89 senior high school classes in Shaoxing City as the survey population. Data on basic information, commuting travel, road safety behaviors and road safety knowledge awareness were collected through questionnaires, and the prevalence of RTIs in the past year was analyzed. Results: A total of 6 287 middle school students were surveyed, and 971 cases of RTIs were reported, with a reporting rate of 15.44%. The reporting rate of RTIs was higher in males than in females (17.68% vs. 13.34%, P<0.05). The reporting rate of RTIs was higher in high school students than in junior high school students (17.70% vs. 12.66%, P<0.05). The students who mainly walked to school (18.00%), walked 5 days a week (17.82%) and traveled with classmates (17.58%) had higher reporting rates of RTIs. Among those who walked for ≥20 minutes, the reporting rate of RTIs was higher in males than in females (P<0.05). Among different road safety behaviors, the reporting rate of RTIs was higher in males than in females who used electronic devices (P<0.05). The reporting rates of RTIs were relatively high among students who played for ≥10 minutes on the way (32.92%), crossed traffic lights directly when being late for school (41.54%) and crossed traffic barriers directly (30.67%). The reporting rate of RTIs among middle school students decreased with the increase of road safety knowledge scores (P<0.05). Conclusions Male students, high school students, students with road risky behaviors and with low awareness of road safety knowledge have higher reporting rates of RTIs. It is necessary to strengthen road safety knowledge education for students.

Objective:To systematically investigate the short-term efficacy of total knee arthroplasty in the treatment of osteoarthritis coupled with fixed patellar dislocation.Methods:A retrospective analysis was conducted on a cohort of 11 patients diagnosed with knee osteoarthritis and fixed patellar dislocation who underwent total knee arthroplasty at Panzhihua Central Hospital from January 2018 to October 2021. The cohort comprised 4 males and 7 females, aged 63.45±4.76 years (range, 56-70 years), all of whom underwent unilateral surgery. There were 5 left and 6 right knees, with a body mass index of 23.20±2.02 kg/m 2 (range, 20.8-27.6 kg/m 2) and a disease course of 12.63±4.81 years. According to the American Society of Anesthesiologists classification, 9 cases were categorized as grade II, and 2 cases as grade III. Recovery of patellar trajectory during total knee arthroplasty, using medial synovial flap transposition to repair lateral joint capsule. Preoperative and postoperative assessments included knee joint range of motion, Knee Society score (KSS), University of California Los Angeles (UCLA) score, and visual analogue scale (VAS). Results:All 11 patients were followed up for a period of 28.64±4.01 months (range, 24-36 months). Two patients exhibited subcutaneous fat liquefaction locally after surgery, which resolved following dressing changes. All wounds achieved primary healing. Two of them developed intramuscular vein thrombosis after surgery and were cured after anticoagulant treatment. The range of motion of the knee joint increased from 63.18°±17.07° before surgery to 104.55°±16.80° at the last follow-up, with a statistically significant difference ( t=14.041, P<0.001). The KSS score increased from 38.00±6.78 points to 80.91±5.65 points, with a statistically significant difference ( t=16.472, P<0.001). The UCLA score increased from 3.18±1.17 to 6.73±1.35, with a statistically significant difference ( t=9.694, P<0.001). The VAS decreased from 6.09±0.94 points to 2.32±0.64 points, with a statistically significant difference ( t=16.600, P<0.001). At the last follow-up, imaging examinations showed no cases of patellar subluxation or dislocation, no tearing or breakage of the knee extension device, and no infection or loosening around the prosthesis. Conclusion:Utilizing medial synovial flap transposition for repairing the lateral joint capsule proves to be an effective technique for key capsule repair. Total knee arthroplasty for osteoarthritis combined with fixed patellar dislocation demonstrates satisfactory early clinical outcomes.

Objective To explore the mediating effect of triglyceride-glucose(TyG)index on the risk of proteinuria in patients with type 2 diabetes mellitus(T2DM).Methods 734 patients with T2DM who underwent routine physical examination in Quyang Road Community Health Service Center,Shanghai from March 2023 to May 2023 were enrolled.The results of basic information,biochemical indicators,abdominal ultrasound and other results were collected.All patients were divided into the normal group,microproteinuria group,and massiveproteinuria group,and stratification analyses were underwent according to glycated hemoglobin(HbA1c),body mass index(BMI),TyG index,and presence or absence of non-alcoholic fatty liver disease(NAFLD).Factors affecting proteinuria in T2DM patients were analyzed.Multivariate logistic regression was used to analyze the impact of TyG index and NAFLD on proteinuria in type 2 diabetes population.Regression coefficient sequential test was used to analyze whether TyG mediates NAFLD associated proteinuria.Results There were statistically significant differences in age,BMI,urinary creatinine,HbA1c,TyG index,etc.among the normal group,microproteinuria group,and massiveproteinuria group(all P＜0.05);there was no statistically significant difference in gender among the three groups.Multivariate logistic regression analysis showed that taking the HbA1c＜7％and BMI＜24 kg/m2 group as a reference,the patients with HbA1c≥7％and BMI≥24 kg/m2 had the highest risk of proteinuria(P=0.022),followed by the HbA1c≥7％and BMI＜24 kg/m2 group(P=0.039).Taking the TyG index(7.65-8.69)as a reference,the risk of proteinuria in the(9.45-11.90)group was 3.321 times(P＜0.001).The mediation effect analysis showed that the TyG mediated NAFLD associated proteinuria(P＜0.001),with the mediation effect accounting for 55.70％of the total effect.Conclusion TyG index may be an independent risk factor for proteinuria in patients with T2DM,and the prevalence of proteinuria is high in patients with poor control in HbA1c and excessive BMI,and TyG may partially mediate the risk of proteinuria in patients with T2DM.
