Degenerative retinoschisis(RS)is a common peripheral retinal degeneration that typically remains asymptomatic and follows a benign clinical course. However, its morphological resemblance to rhegmatogenous retinal detachment(RRD)presents a diagnostic challenge, as the two conditions demand fundamentally different management and carry distinct prognoses. Precise differentiation is therefore clinically imperative. Recent advances in multimodal imaging have substantially refined the diagnostic accuracy and differential assessment of degenerative RS, establishing spectral-domain optical coherence tomography(SD-OCT)as the definitive reference standard. When the disease progresses to progressive symptomatic schisis-related retinal detachment(PSSRD), prompt surgical intervention, including scleral buckling, pars plana vitrectomy, or a combined approach, is mandated to preserve visual function. Clinical decision-making must be individualized, with the surgical strategy carefully tailored to the specific characteristics of eachcase. This review provides a systematic synthesis of current evidence on the natural history, imaging hallmarks, and surgical management of degenerative RS and its complications, aiming to inform and optimize clinical practice.

Objective To understand the epidemiological characteristics of HIV-positive patients in Wuhan from 2013 to 2022, and to further discover the high-risk groups, high-risk factors and high-risk links of AIDS in Wuhan. Methods The data of 21212 HIV antibody confirmed positive cases submitted for examination in Wuhan Comprehensive AIDS Management Platform from 2013 to 2022 were collected. A chi-square test was conducted on the data using SPSS software, and the results were analyzed. Results The number of confirmed tests showed an overall increasing trend from 2013 to 2022 (χ²=252.92, P＜0.001). Among the 12 448 confirmed positive cases, the male to female ratio was 7.44:1. The number of cases in 20-years age group was the highest (32.96%). The proportion of males in 60-years age group showed an increasing trend year by year (χ²=13.222, P＜0.005). Most of the cases were divorced/widowed/unmarried (5655 cases, 45.43%，χ²=296.166，P＜0.001). The majority were college students or above (3190 cases, 25.63%), and there was an increasing trend year by year (χ²=384.615，P＜0.001). The top three occupations were housework and unemployment, students, and business services (χ²=1225.833, P＜0.001). The patient detection and preoperative detection were the most among the sources (χ²=4941.911, P＜0.001). Medical institutions sent the most cases for testing, but the positive rate was low (49.37%, χ²=2571.462, P＜0.001). Conclusion The overall number of confirmatory tests shows an increasing trend. It is recommended to supplement other diagnostic criteria and methods to improve the accuracy of positive rates in medical institutions. Efforts should be intensified to intervene in the elderly population, strengthen AIDS prevention education in schools, and raise awareness of AIDS prevention among young people.

Objective:Investigating the correlation between postoperative stress levels and intraoperative sufentanil dosage in breast cancer patients.Method:A retrospective selection was made of 100 BC patients who underwent surgery at Shaanxi Cancer Hospital from Apr. 2023 to Apr. 2025 as the research subjects. According to the dosage of sufentanil during the operation, they were divided into low-dose ( n=33), medium-dose ( n=34), and high-dose ( n=33) groups. The general data and postoperative stress levels of the three groups were compared and analyzed. Based on the results of stress levels, BC patients were further divided into the normal group ( n=75) and the elevated group ( n=25). The clinical data, laboratory indicators, and intraoperative sufentanil dosage of the two groups were compared and analyzed. Binary Logistic regression was used to analyze the factors influencing the postoperative stress level of patients, and a nomogram was constructed. ROC and DCA were used to analyze the predictive value and net benefit of the nomogram. Pearson correlation analysis was used to analyze the correlation between the factors influencing the stress state of patients and the postoperative stress level. Results:The levels of endothelin-1 (ET-1), norepinephrine (NE), and cortisol (Cor) in the high-dose group after surgery were significantly lower than those in the low-dose group and the medium-dose group ( t=9.55, 11.07, 82.91, P<0.05). The stress levels and the levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), brain-derived neurotrophic factor (BDNF), and adrenocorticotropic hormone (ACTH) in the stress group were significantly higher than those in the normal group. However, the levels of sufentanil drug, glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) were lower than those in the normal group ( t=2.02, 2.04, 2.15, P<0.05). Multivariate analysis of binary logistic regression showed that the dosage of sufentanil ( t=2.02, 2.04, 2.15, P<0.05) ; Multivariate analysis of binary logistic regression showed that sufentanil dosage ( OR=0.58, 95 %CI: 0.24-0.93), SOD ( OR= 0.63, 95 %CI:0.41~0.84) were protective factors, and ACTH ( OR=1.57, 95%CI:1.23-1.92), CRP ( OR=1.53, 95 %CI: 1.06-2.00) 、BDNF ( OR=1.43, 95 %CI:1.11-1.75) were risk factors affecting the stress state of patients ( P<0.05) ; The construction of a risk nomogram model based on the above influencing factors and the ROC analysis indicated that its AUC=0.829, indicating a good predictive ability. The correction curve is close to the ideal curve, indicating that the model has good discrimination and consistency. DCA curve verification revealed that its predicted probability was 68%, indicating a positive net benefit. Correlation analysis showed that the intraoperative sufentanil dose, SOD, ACTH, CRP, BDNF were significantly correlated with the postoperative stress level-related indicators NE, ET-1, Cor. Among them, the intraoperative sufentanil dose and SOD were negatively correlated with NE, ET-1, Cor, while the other indicators were positively correlated with them ( P<0.05) . Conclusions:High levels of ACTH, CRP and BDNF are independent risk factors for postoperative stress in patients with BC, while sufentanil fibroids and SOD during the operation are protective factors. Moreover, the intraoperative sufentanil dose has a significant correlation with the related indicators of emergency levels. Clinically, this can be used as a biomarker for predicting postoperative stress in patients with BC and individualized intervention measures can be implemented, providing a new monitoring perspective for clinical prediction of the occurrence of stress.

Objective:To investigate the efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.

OBJECTIVE To investigate the stability of 5-fluorouracil （5-FU） in human blood and to establish a standardized clinical sampling and delivery procedure for therapeutic drug monitoring （TDM） of 5-FU. METHODS The EDTA-anticoagulated whole blood was used as the matrix to prepare stability assessment samples of 5-FU at both low （200 ng/mL） and high （5 000 ng/mL） concentrations （with groups without stabilizer and with 1% volume ratio of stabilizer）. The stability assessment samples were placed under room temperature （[ 25±2） ℃] and refrigerated （2-8 ℃） conditions， with sampling at 0， 0.5， 1， 2， 4， 7， and 24 h. After vortexing and centrifugation， the upper plasma layer was collected； proteins were precipitated using methanol， and the concentration of 5-FU in plasma was determined by liquid chromatography-tandem mass spectrometry. Based on the whole blood stability results， clinical sampling and delivery procedures were established. RESULTS The concentration of 5-FU in blank whole blood samples without stabilizers was significantly lower than that in samples with stabilizers （P＜0.05）. However， varying volumes （10， 25， 50 μL） of stabilizers had no significant effect on the measured concentrations of 5-FU in stability assessment samples with low and high concentrations （P＞0.05）. Without the addition of a stabilizer， low- and high-concentration 5-FU whole blood samples remained stable at room temperature for 0.5 h and 1 h， respectively， and under refrigeration for 2 h and 7 h， respectively. After the addition of a 1% stabilizer， the whole blood samples remained stable for up to 24 h under both room temperature and refrigerated conditions. Based on these findings， the following procedure was established： after collection， whole blood samples could be temporarily stored at room temperature （≤0.5 h） or at 4　℃ （≤2 h）， and transported at 2-8　℃. Upon delivery to the laboratory， a 1% volume ratio of stabilizer must be added immediately， followed by centrifugation within 24 h. The resulting plasma should be stored at －20 ℃ . CONCLUSIONS 5-FU in whole blood exhibits poor stability at room temperature. Refrigeration at 2-8　℃ slightly improves stability ， but degradation still occurs rapidly. Adding a stabilizer at a 1% volume ratio significantly prolongs the refrigerated storage time. The established sampling and transport procedure for 5-FU TDM innovatively introduces the stabilizer addition step at the laboratory sample reception stage （rather than immediately after blood draw）. This approach ensures analytical quality while offering greater adaptability to real-world clinical sampling conditions， significantly improving practical feasibility.

Portal vein thrombosis （PVT） is one of the common complications during the natural course of liver cirrhosis and has an important influence on the progression of liver cirrhosis. This article mainly summarizes the research advances in the risk factors for PVT. There are many risk factors for PVT， and Virchow’s triad， namely venous stasis， hypercoagulability， and vascular endothelial injury and systemic inflammation caused by surgery or trauma， are considered the main reasons for the development and progression of PVT. At present， more prospective studies are still needed to validate the predictive models for the risk of PVT that have certain application prospects in clinical practice. Cirrhotic patients with PVT tend to have a poor prognosis， and complete obstructive PVT is associated with increased mortality after liver transplantation. Recent studies have shown that prophylactic anticoagulant therapy is safe and effective in patients with liver cirrhosis and can thus help with the prevention and treatment of PVT.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective Atrial fibrillation(AF)is a disease of high heterogeneity,and the association between AF phenotypes and the outcome of different catheter ablation strategies remains unclear.Conventional classification of AF(e.g.according to duration,atrial size,and thromboembolism risk)fails to provide reference for the optimal stratification of the prognostic risks or to guide individualized treatment plan.In recent years,research on machine learning has found that cluster analysis,an unsupervised data-driven approach,can uncover the intrinsic structure of data and identify clusters of patients with pathophysiological similarity.It has been demonstrated that cluster analysis helps improve the characterization of AF phenotypes and provide valuable prognostic information.In our cohort of AF inpatients undergoing radiofrequency catheter ablation,we used unsupervised cluster analysis to identify patient subgroups,to compare them with previous studies,and to evaluate their association with different suitable ablation patterns and outcomes.Methods The participants were AF patients undergoing radiofrequency catheter ablation at West China Hospital between October 2015 and December 2017.All participants were aged 18 years or older.They underwent radiofrequency catheter ablation during their hospitalization.They completed the follow-up process under explicit informed consent.Patients with AF of a reversible cause,severe mitral stenosis or prosthetic heart valve,congenital heart disease,new-onset acute coronary syndrome within three months prior to the surgery,or a life expectancy less than 12 months were excluded according to the exclusion criteria.The cohort consisted of 1 102 participants with paroxysmal or persistent/long-standing persistent AF.Data on 59 variables representing demographics,AF type,comorbidities,therapeutic history,vital signs,electrocardiographic and echocardiographic findings,and laboratory findings were collected.Overall,data for the variables were rarely missing(<5% ),and multiple imputation was used for correction of missing data.Follow-up surveys were conducted through outpatient clinic visits or by telephone.Patients were scheduled for follow-up with 12-lead resting electrocardiography and 24-hours Holter monitoring at 3 months and 6 months after the ablation procedure.Early ablation success was defined as the absence of documented AF,atrial flutter,or atrial tachycardia>30 seconds at 6-month follow-up.Hierarchical clustering was performed on the 59 baseline variables.All characteristic variables were standardized to have a mean of zero and a standard deviation of one.Initially,each patient was regarded as a separate cluster,and the distance between these clusters was calculated.Then,the Ward minimum variance method of clustering was used to merge the pair of clusters with the minimum total variance.This process continued until all patients formed one whole cluster.The"NbClust"package in R software,capable of calculating various statistical indices,including pseudo t2 index,cubic clustering criterion,silhouette index etc,was applied to determine the optimal number of clusters.The most frequently chosen number of clusters by these indices was selected.A heatmap was generated to illustrate the clinical features of clusters,while a tree diagram was used to depict the clustering process and the heterogeneity among clusters.Ablation strategies were compared within each cluster regarding ablation efficacy.Results Five statistically driven clusters were identified:1)the younger age cluster(n=404),characterized by the lowest prevalence of cardiovascular and cerebrovascular comorbidities but the highest prevalence of obstructive sleep apnea syndrome(14.4% );2)a cluster of elderly adults with chronic diseases(n=438),the largest cluster,showing relatively higher rates of hypertension,diabetes,stroke,and chronic obstructive pulmonary disease;3)a cluster with high prevalence of sinus node dysfunction(n=160),with patients showing the highest prevalence of sick sinus syndrome and pacemaker implantation;4)the heart failure cluster(n=80),with the highest prevalence of heart failure(58.8% )and persistent/long-standing persistent AF(73.7% );5)prior coronary artery revascularization cluster(n=20),with patients of the most advanced age(median:69.0 years old)and predominantly male patients,all of whom had prior myocardial infarction and coronary artery revascularization.Patients in cluster 2 achieved higher early ablation success with pulmonary veins isolation alone compared to extensive ablation strategies(79.6% vs.66.5%;odds ratio[OR]=1.97,95% confidence interval[CI]:1.28-3.03).Although extensive ablation strategies had a slightly higher success rate in the heart failure group,the difference was not statistically significant.Conclusions This study provided a unique classification of AF patients undergoing catheter ablation by cluster analysis.Age,chronic disease,sinus node dysfunction,heart failure and history of coronary artery revascularization contributed to the formation of the five clinically relevant subtypes.These subtypes showed differences in ablation success rates,highlighting the potential of cluster analysis in guiding individualized risk stratification and treatment decisions for AF patients.
