AIM: To evaluate the safety and efficacy of low-dose transscleral cyclophotocoagulation(TSCP)in the management of persistent ocular hypertension after an acute attack of angle-closure glaucoma(AACG).METHODS:This retrospective study enrolled patients diagnosed with persistent ocular hypertension after an acute AACG attack at the No.988 Hospital of the Joint Logistics Support Force of the Chinese PLA between September 2023 and September 2024. All patients underwent low-dose TSCP using a semiconductor diode laser. Subsequent cataract surgery combined with goniosynechialysis was performed once intraocular pressure(IOP)was stabilized. Changes in anterior chamber depth(ACD), best-corrected visual acuity(VA), and IOP were compared before and after TSCP, as well as before and after phacoemulsification. Post-TSCP complications were also documented.RESULTS: A total of 21 patients(21 eyes)were enrolled, including 8 males and 13 females, with a mean age of 67.95±7.25 y. Compared with pre-cyclophotocoagulation values, ACD increased significantly at 3 d post-TSCP(1.49±0.18 vs 1.22±0.21 mm; P<0.001). BCVA and IOP decreased significantly at 1 d post-TSCP, pre-phacoemulsification, 1 wk post-phacoemulsification, and 1 mo post-phacoemulsification compared with pre-TSCP IOP(all P<0.01). Regarding postoperative complications, 2 eyes experienced pain on the day of the procedure, 5 eyes developed mild corneal endothelial folds, 2 eyes exhibited moderate anterior chamber inflammatory reaction, and 12 eyes showed shallow ciliary body detachment. No serious complications occurred during the 1-month follow-up period.CONCLUSION:Low-dose TSCP appears to be an effective bridging therapy for patients with persistent ocular hypertension following an AACG attack. It facilitates rapid IOP reduction, alleviates symptoms, and helps preserve visual function with a favorable safety profile, thereby reducing the risks associated with subsequent intraocular surgery.

ObjectiveProtein-protein interactions (PPIs) are fundamental to the execution of biological functions within living cells. However, traditional biochemical methods, such as co-immunoprecipitation (Co-IP), often fail to capture transient, weak, or membrane-associated interactions due to the stringent detergent requirements for cell lysis. Proximity labeling (PL) has emerged in recent years as a transformative technology for mapping the proteomes of specific subcellular compartments and identifying dynamic interactomes in situ. Golgi protein 73 (GP73, also known as GOLPH2), a resident type II Golgi transmembrane protein, is a well-recognized clinical biomarker for liver diseases, including hepatocellular carcinoma (HCC). Despite its clinical significance, the comprehensive physiological and pathological functions of GP73 remain partially understood. This study aims to establish an APEX2-mediated proximity labeling system specifically targeting GP73 to map its interactome in a living cellular environment, thereby providing new insights into its molecular roles and regulatory mechanisms. MethodsTo achieve spatial specificity, we first constructed a stable cell line expressing a fusion protein consisting of GP73 and the engineered soybean peroxidase APEX2. The localization of the GP73-APEX2 fusion protein was validated to ensure it correctly targeted the Golgi apparatus. The proximity labeling reaction was initiated by incubating the cells with biotin-phenol (BP) for 30 min, followed by a brief (1 min) treatment with1 mmol/L hydrogen peroxide (H₂O₂). This catalytic reaction converts BP into highly reactive, short-lived biotin-phenoxyl radicals that covalently attach to endogenous proteins within a small labeling radius of the GP73-APEX2 enzyme. Subsequently, the cells were quenched, and biotinylated proteins were enriched using high-affinity streptavidin-coated magnetic beads. The captured “neighbor” proteins were subjected to on-bead digestion and analyzed via liquid chromatography-tandem mass spectrometry (LC-MS/MS) for high-throughput identification. Rigorous bioinformatics analysis, including Gene Ontology (GO) enrichment, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and protein-protein interaction network mapping, was performed to interpret the biological significance of the identified candidates. ResultsOur results demonstrate the successful establishment of a robust and sensitive APEX2-based proximity labeling system for GP73. We identified a total of 95 high-confidence interacting proteins that were significantly enriched in the GP73 proximity proteome compared to control groups. Bioinformatics analysis revealed that these interactors were predominantly associated with biological processes such as vesicular transport, protein localization, and, most notably, molecular functions related to “ribosome binding” and “translation regulation”. This suggested an unexpected role for the Golgi-resident GP73 in the cellular translation machinery. To validate these findings, we performed targeted biochemical assays which confirmed a direct interaction between GP73 and the subunits of the eukaryotic translation initiation factor 3 (eIF3) complex, specifically EIF3G and EIF3I. Furthermore, functional validation using the surface sensing of translation (SUnSET) assay—a non-radioactive method to monitor protein synthesis—revealed that the overexpression of GP73 significantly promoted global protein translation levels in the cell, whereas its depletion or inhibition resulted in reduced translation efficiency. ConclusionThis study successfully utilized APEX2-mediated proximity labeling to provide the first systematic map of GP73 interactome in living cells. Our findings uncover a novel, unconventional function of GP73 as a regulator of cellular protein translation, likely mediated through its interaction with the eIF3 complex. This discovery significantly broadens our understanding of the biological roles of GP73 beyond its traditional function in the Golgi apparatus and suggests that it may act as a bridge between Golgi-related trafficking and the protein synthesis machinery. Furthermore, the technical framework established in this study provides a valuable template for investigating other complex organelle-associated protein networks and resolving transient macromolecular interactions in various physiological and pathological contexts.

BackgroundPersistent cognitive impairment is prevalent among patients with stable schizophrenia. While serum total bile acid （TBA） level in acute-phase patients are known to be associated with cognitive dysfunction， the relationship between serum TBA and multi-dimensional cognitive functions in stable phase patients remains unclear. ObjectiveTo investigate the correlation between serum TBA level and cognitive function in patients with stable schizophrenia， and to evaluate its predictive value for cognitive impairment， thereby providing a serological biomarker for the timely identification and objective assessment of cognitive dysfunction. MethodsA cross-sectional study was conducted on 137 inpatients with stable schizophrenia at The Fourth People's Hospital of Yancheng from March to December 2024. All participants met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. Cognitive function was evaluated using the Chinese Brief Cognitive Test （C-BCT）， patients were categorized into four groups： normal cognition （n=28）， mild impairment （n=28）， moderate impairment （n=47）， and severe impairment （n=34）. Fasting venous blood samples were collected， and serum TBA level was quantified using an enzymatic cycle assay. Spearman correlation analysis was ultilized to determine the relationship between serum TBA level， overall cognitive function， and specific cognitive domains. Binary Logistic regression model was used （adjusting for covariates such as age， gender， and disease duration） to analyze the impact of serum TBA level on overall and individual cognitive functions. The predictive value of serum TBA level for overall cognitive impairment was evaluated using receiver operating characteristic （ROC） curve. ResultsSerum TBA levels differed significantly among the four groups （H=18.677， P<0.01）. Specifically， serum TBA levels in both the moderate and severe cognitive impairment groups were significantly higher than those in the normal cognitive group （adjusted P<0.01）. Serum TBA level was positively correlated with the severity grading of overall cognitive impairment （r_s=0.354， P<0.05）， and negatively correlated with T-scores on the trail making test （r_s=-0.328， P<0.05）， continuous performance test （r_s=-0.247， P<0.05）， digit span （r_s=-0.265， P<0.05）， and symbol coding （r_s=-0.221， P<0.05）. Binary Logistic regression analysis identified serum TBA level as an independent risk factor for overall cognitive impairment （OR=1.322， 95% CI： 1.021 - 1.713， P=0.034）， with a particularly robust predictive ability for impaired information processing speed （OR=1.325， 95% CI： 1.057 - 1.661， P=0.015）. The area under ROC curve （AUC） for serum TBA level in predicting overall cognitive impairment was 0.738， with a sensitivity of 60.61% and a specificity of 78.64%. ConclusionIn patients with stable schizophrenia， elevated serum TBA levels are associated with worse overall cognitive function， as well as deficits in information processing speed， attention， working memory， and executive function. Serum TBA serves as an independent risk factor and exhibits moderate predictive value for overall cognitive impairmen，particularly in the domain of information processing speed. ［Funded by Yancheng Municipal Health Commission Medical Research Project （number， YK2024141）］

Objective To explore the prevalence of depressive symptoms in postoperative patients with ovarian cancer and to analyze its influencing factors from multiple dimensions, including clinical characteristics, psychological factors, and laboratory indicators. Methods A cross-sectional study was conducted, which enrolled 235 postoperative patients with ovarian cancer. Depressive status was assessed using the patient health questionnaire, and the demographic, pathological, and medical record data of the patients were collected using the generalized anxiety disorder scale, Pittsburgh sleep quality index, European organization for research and treatment of cancer quality of life questionnaire core 30, and ECOG performance status score. Peripheral blood tumor marker (CA125), routine blood test, lymphocyte subsets, and serum cytokine levels were measured. Univariate and multivariate binary logistic regression analysis were used for statistical analysis. Results The prevalence of depression in postoperative patients with ovarian cancer was 39.15% (92/235). Univariate analysis showed that ECOG score ≥ 2 points, pain, anxiety, poor sleep quality, low quality of life, low life satisfaction, tumor recurrence, six or more cycles of chemotherapy, as well as higher levels of CA125, NLR, and NAR, and lower hemoglobin levels were significantly associated with depression (all P<0.05). Multivariate binary Logistic regression analysis showed that anxiety (OR=1.975, 95%CI: 1.231-3.170), sleep efficiency (OR=4.181, 95%CI: 1.211-14.43), sleep latency (OR=34.806, 95%CI: 4.258-284.542), ECOG performance status score, cognitive function (OR=0.918, 95%CI: 0.868-0.97), and life satisfaction were independent risk factors for depression (all P<0.05). Laboratory indicators were not independent influencing factors in the multivariate Logistic regression model. Conclusion Depression in postoperative patients with ovarian cancer is influenced by physiological, psychological, and social factors. Clinical management should focus on patients with anxiety, sleep disorders, poor physical condition, and low life satisfaction, and a comprehensive prevention and treatment strategy centered on psychological intervention and taking into account symptom management and social support should be implemented.

Objective To compare the safety of laparoscopic pancreatoduodenectomy(LPD)and open pancreatoduodenectomy(OPD)and analyze the learning curve and safety at different stages of LPD.Methods A retrospective analysis was conducted on the clinical data of 50 LPD patients and 54 OPD patients in the Department of Hepatopancreatobiliary Surgery of Suzhou Hospital Affiliated to Nanjing Medical University from January 2020 to June 2024,and intraoperative and postoperative conditions were compared.The Cumulative Sum(CUSUM)analysis method was used to analyze the technical nodes of the LPD learning curve.Results There were no significant differences in operation time and intraoperative blood loss between the LPD group and the OPD group(P＞0.05).There was also no significant difference in the incidence rates of pancreatic fistula(grade B and C),delayed gastric emptying,postoperative bleeding,biliary fistula and intra-abdominal infection between the LPD group and the OPD group(P＞0.05).A time series plot of operation time was drawn based on the patient's operation time and surgical sequence,yielding a fitted curve.Curve analysis showed initial stage and stable stage were finished at the 17th and 24th cases.The LPD learning curve could be divided into three stages:stage Ⅰ characterized as the initial stage(cases 1 to 17),stage Ⅱ characterized as the stable stage(cases 18 to 24),and stage Ⅲ characterized as the proficient stage(cases 25 to 50).The operation time in stages Ⅱ and Ⅲ was significantly shorter than that in stage Ⅰ,and the intraoperative blood loss in stage Ⅰ was significantly higher than that in stage Ⅲ(P＜0.05).There was no significant difference in the incidence of complications among the three stages(P＞0.05).Conclusion LPD and OPD show no significant differences in indications and safety.The LPD learning curve can be divided into three stages.As the number of surgeries completed increa-ses,the operation time of physicians gradually shortens,and the incidence of complications of patients gradually decreases.

Objective To investigate the correlation between adiponectin/leptin(Adpn/Lep)ratio and risk of heart failure with preserved ejection fraction(HFpEF).Methods A total of 84 hospi-talized HFpEF patients(HFpEF group)and 84 age-and sex-matched non-heart failure patients(control group)admitted in Xiangyang Central Hospital between October 2023 and April 2024 were recruited in this study.Serum Adpn and Lep levels were measured using ELISA.Spearman correlation analysis was applied to assess the relationship between the Adpn/Lep ratio and other HFpEF-related parameters.Univariate and multivariate logistic regression analyses were per-formed to identify risk factors for HFpEF.ROC curve was plotted to evaluate the auxiliary diag-nostic value of the Adpn/Lep ratio for HFpEF.Results The HFpEF group exhibited significantly higher leptin level,but lower Adpn level and Adpn/Lep ratio when compared with the control group(P＜0.01).Spearman correlation analysis revealed that Adpn/Lep ratio was negatively cor-related with N-terminal fragment of brain natriuretic peptide prohormone and left atrial diameter(r=-0.476,r=-0.328,P＜0.01)in HFpEF patients.Multivariate logistic regression analysis identified the Adpn/Lep ratio as an independent risk factor for HFpEF(P＜0.01).ROC curve analysis demonstrated that the AUC value of Adpn/Lep ratio,Adpn,and Lep in predicting HFpEF was 0.818(95％CI:0.747-0.888),0.639(95％CI:0.544-0.734)and 0.638(95％CI:0.550-0.726),respectively,and the ratio obtained better predictive performance than the two indicators(P＜0.01).Conclusion Adpn/Lep ratio is associated with HFpEF.Lower Adpn/Lep ratio has good auxiliary diagnostic value for HFpEF.The ratio can better predict the occurrence of HFpEF than Adpn and Lep alone.

Objective To explore the impact of preoperative fibrinogen levels on the 1-year adverse outcomes after endovascular revascularization in patients with diabetes complicated with lower extremity arteriosclerosis obliterans(LEASO).Methods We collected the baseline clinical data of 289 patients with diabetes complicated with LEASO,who were admitted to The First Affiliated Hospital of Xi'an Jiaotong University from May 2020 to December 2022 for endovascular revascularization.All patients were followed up for 13 to 24 months after interventional therapy,with the follow-up information including major adverse cardiovascular events(MACEs)such as all-cause death,acute myocardial infarction and acute stroke,as well as major adverse lower extremity events(MALEs)such as rest pain in the lower extremities,ulcers or skin defects,gangrene,reocclusion and amputation.A multivariable Cox regression model was used to analyze the related risk factors for adverse outcomes 1 year after endovascular revascularization in patients with diabetes complicated with LEASO,and receiver operating characteristic(ROC)curves were constructed to evaluate the predictive efficacy and optimal cutoff value of fibrinogen levels for endpoint events,and Kaplan-Meier survival curves were drawn.Sensitivity analysis was made to assess the differences in the impact of fibrinogen on endpoint events across various subgroups.Results We recruited a total of 289 patients(55 patients in MACEs and 234 in non-MACEs;68 patients in MALEs and 221 in non-MALEs),with a mean age of 67.6±9.3 years,including 215 males.Multivariate Cox regression analysis showed that elevated plasma fibrinogen was an independent risk factor for MACEs(HR=1.250,95％CI:1.053-1.484,P=0.011)and all-cause death(HR=1.297,95％CI:1.030-1.633,P=0.027)in the cohort followed up 1 year after interventional therapy,but had no significant impact on the occurrence of MALEs(P=0.625).Baseline plasma fibrinogen level 4.32 g/L was the optimal cutoff value for predicting MACEs(sensitivity=0.673,95％CI:0.582-0.767;specificity=0.688,95％CI:0.562-0.775)and all-cause death(sensitivity=0.679,95％CI:0.483-0.880;specificity=0.651,95％CI:0.465-0.755).The AUC for predicting MACEs and all-cause death after interventional therapy was 0.652(95％CI:0.564 2-0.739 1)and 0.619(95％CI:0.507-0.733),respectively.After a median follow-up of 14.03 months,patients with preoperative fibrinogen level ≥ 4.32 g/L had a significantly higher risk of MACEs and all-cause death compared to patients with preoperative fibrinogen＜4.32 g/L(P＜0.001),and there were no significant differences in different subgroups,including gender(male/female,interaction P=0.836),age(＜65 years/≥65 years,interaction P=0.211),smoking status(never smoked/current or former smoker,interaction P=0.779),chronic kidney disease(yes/no,interaction P=0.360),and heart failure(yes/no,interaction P=0.114).Conclusion Preoperative plasma fibrinogen≥4.32 g/L is an effective indicator for predicting MACEs and all-cause mortality following endovascular revascularization in patients with diabetes and LEASO.

Objective:To explore the influencing factors of swallowing function after stroke based on the semi-quantita-tive assessment of the videofluoroscopic dysphagia scale(VDS),to provide a basis for clinical screening and treatment.Method:A retrospective survey method was conducted on 120 stroke patients who met the inclusion criteria.Clinical characteristics were collected,including gender,age,type of stroke,lesion location,disease duration,food consistency,nasogastric tube placement,tracheostomy,and comorbidities.All patients underwent a video-fluoroscopic swallowing study(VFSS),and swallowing function was assessed using the videofluoroscopic dys-phagia scale(VDS).Univariate and multivariate linear regression analyses were conducted to examine the ef-fects of clinical characteristics on oral phase,pharyngeal phase,and global swallowing function.Result:Univariate analysis revealed that subcortical lesions in the middle cerebral artery(MCA)region(ex-cluding the basal ganglia)(P＜0.001),basal ganglia lesions(P=0.040),and medullary lesions(P＜0.001)were significantly associated with global swallowing function after stroke.Multivariate linear regression analysis indi-cated that medullary lesions(P＜0.001),subcortical lesions in the MCA region(excluding the basal ganglia)(P＜0.001),and MCA(including basal ganglia)lesions(P=0.019)were risk factors for global swallowing function after stroke.Regarding food consistency,consumption of thickened liquids(P=0.018)and pureed foods(P=0.006)were protective factors for global swallowing function.Subgroup analysis of global swallow-ing function revealed that MCA(including basal ganglia)lesions(P=0.003),female gender(P＜0.001)and tra-cheotomy(P＜0.001)were risk factors for oral phase swallowing function after stroke.Compared with patients without a gastrostomy tube,those with a gastrostomy tubes(P=0.034)had less effect on swallowing function in the oral phase.Compared with hemorrhagic stroke,ischemic stroke(P＜0.001)had a less impact on the oral phase swallowing function.Medullary lesions(P＜0.001)and subcortical lesions in the MCA region(ex-cluding the basal ganglia)(P＜0.001)were risk factors for pharyngeal phase swallowing function.For food con-sistency,the consumption of thickened liquids(P=0.005)and pureed foods(P=0.002)were protective factors for pharyngeal phase swallowing function after stroke.Conclusion:Identifying clinical characteristics in the assessment of swallowing function in stroke patients helps to determine the type of dysphagia and the key points of treatment.This approach may facilitate the de-velopment and implementation of more targeted rehabilitation treatment plans,and accelerate the recovery of swallowing function and feeding ability in stroke patients.

BACKGROUND:Patch clamp technique has been developed for more than 40 years as the"gold standard"for the study of ion channels.However,the research content of scientific research institutions is relatively independent,and the existing research results are not systematically summarized,which leads to the phenomenon of high repeatability and weak innovation in the existing research.Therefore,it is urgent to make a comprehensive review of patch clamp technology to clarify the current research status,hot spots,and future development direction.OBJECTIVE:To summarize the research status and development trend of patch clamp technique in recent 10 years.METHODS:Publications on patch clamp technology from 2013 to 2023 were collected using the Web of Science core collection database.CiteSpace and VOSviewer software were used to quantify the number of publications and analyze the network of literature entries,including countries,institutions,journals,authors,keywords,highly cited literature,and co-cited references.RESULTS AND CONCLUSION:(1)In recent 10 years,the research in the field of patch clamp technology has gradually entered a stage of stable development.(2)China and the United States are the leading countries in this regard.The Chinese Academy of Sciences is an institution with core influence.Journal of Neuroscience is the main publication.Park,Won Sun team(Jeonbuk National University)and Chu,Li team(Hebei Key Laboratory of Chinese Medicine Research on Cardio-Cerebrovascular Disease)have made outstanding contributions in this field,but there is less collaboration and communication between the teams and no network cooperation model has been formed.(3)Patch clamp technology is mainly used in the electrophysiological characteristics of the nervous system and the pathological mechanism of the disease,which is the focus of researchers'continuous attention.(4)In the study of electrophysiological characteristics of cardiovascular system and its pathological mechanism,the electrophysiological characteristics of primary cardiomyocytes and induced pluripotent stem cell-derived cardiomyocytes and the pathological mechanism of atrial fibrillation,cardiotoxicity,sudden cardiac death,hypertension and other cardiovascular diseases have been the focus of research in recent years.(5)In the application of patch clamp technology combined with other biotechnology,it will be an important research direction to focus on the cross fusion with optogenetics,two-photon calcium imaging and other technologies.(6)In the research of drug screening and identification of therapeutic targets,especially the research of patch clamp technology and traditional Chinese medicine compound,it will become a great help in the future research of component traditional Chinese medicine.
