AIM: To evaluate the reliability of a digital multimedia system for measuring near-distance horizontal heterophoria.METHODS: This cross-sectional diagnostic study enrolled patients with refractive errors who visited Shantou Aier Eye Hospital from May 2023 to August 2025, presenting with symptoms of visual fatigue, undergoing myopia management, or receiving routine ophthalmic examinations, and who completed heterophoria testing during this period. All patients wearing full refractive correction underwent near-distance(0.4 m)horizontal heterophoria measurement in a random order using the digital multimedia system, the Von Graefe method, and the Maddox rod method. Two consecutive measurements were performed for each method. The intraclass correlation coefficient(ICC)was used to analyze the measurement repeatability of each method, and Bland-Altman analysis and Spearman correlation analysis were employed to evaluate the consistency between the digital multimedia system and the two traditional methods.RESULTS: A total of 60 patients(120 eyes)were included, comprising 27 males and 33 females, with a mean age of 21.03±7.24 y. Repeatability analysis showed that the ICC for the digital multimedia system was 0.960(95%CI: 0.934-0.976), for the Von Graefe method was 0.979(95%CI: 0.964-0.987), and for the Maddox rod method was 0.956(95%CI: 0.926-0.973), all indicating excellent repeatability. Bland-Altman analysis revealed a mean difference of 0.367△ [95% limits of agreement(LoA): -2.97△ to 3.70△] between the Von Graefe method and the digital system, and a mean difference of 0.067△(95% LoA: -3.05△ to 3.19△)between the Maddox rod method and the digital system. Both differences were within the clinically acceptable range(difference <4△). Spearman correlation analysis showed positive correlations between the digital system and the Von Graefe method(rs=0.867)and between the digital system and the Maddox rod method(rs=0.777, all P<0.001).CONCLUSION: The digital multimedia system demonstrates high repeatability and good consistency with the traditional Von Graefe and Maddox rod methods for measuring near-distance horizontal heterophoria. It shows promise as a new and effective tool for clinical near-distance horizontal heterophoria measurement.

Objective:To evaluate the efficacy of combined cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) in the management of dysphagia secondary to glossopharyngeal and vagal nerve injury.Methods:This retrospective cohort study collected the clinical data of 18 patients with persistent dysphagia due to glossopharyngeal and vagus nerve injuries, who underwent concurrent cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) at the Department of Otolaryngology, Peking Union Medical College Hospital, from January 2017 to December 2024. Pre-and postoperative assessments included electronic flexible laryngoscope, the Chinese version of Swallow Quality-of-Life Questionnaire (CSWAL-QOL), videofluoroscopic swallowing study (VFSS), body weight changes, and nasogastric tube (NGT) removal status with routine follow-up. The comparison of swallowing function before and after surgery was conducted using paired samples t-test and χ2 test. Results:The study cohort comprised 10 male and 8 female patients, with ages ranging from 33 to 70 years (mean±SD: 53.8±10.5). All surgical procedures were completed successfully without complications. During the 6-to 24-month follow-up period, 10 of the 13 patients who were initially nasogastric tube-dependent achieved successful decannulation. Compared with preoperative values, postoperative measurements demonstrated statistically significant improvements across all parameters: mean body weight increased from (56.95±9.14) kg to (59.22±8.72) kg ( t=3.689 , P<0.01), CSWAL-QOL scores improved from 91.89±17.81 to 130.83±25.42 ( t=6.921 , P<0.01), while, both VFSS scales showed marked reductions (VFSS-SWAL: 6.78±1.40 to 3.39±1.61, t=-8.001, P<0.01; PAS: 6.56±1.15 to 2.94±1.26, t=-10.114, P<0.01). Conclusions:Combined CPM and AFIL represents an effective surgical approach for dysphagia following glossopharyngeal and vagal nerve injury, thereby demonstrating significant improvements in both swallowing function and quality of life.

Objective To determine the effects of cardiac resynchronization therapy at different pacing sites on electrocardiogram(ECG),left ventricular(LV)function and adverse events in elderly patients with heart failure(HF).Methods A total of 214 elderly HF patients admitted to our department between July 2021 and July 2024 were retrospectively recruited.According to different pacing sites in cardiac resynchronization therapy,they were divided into His bundle group(102 cases)and left bundle branch group(112 cases).Their grades of New York Heart Association(NYHA)cardiac function,duration of QRS complex,pacing parameters(pacing threshold,pacing perception,pacing resistance),cardiac function indicators,LV function,LV systolic synchrony[standard deviation of time to peak longitudinal strain,to peak radial strain and to peak circumferential strain(Tls-SD,Trs-SD and Tcs-SD)],and incidence of adverse events were compared between the two groups before and at 6 months after cardiac pacemaker implantation.Results In 6 months after surgery the left bundle branch group had significantly lower N-terminal pro-B-type natriuretic peptide level,smaller LV end-diastolic diameter and LV end-systolic diameter,decreased Tls-SD,Trs-SD and Tcs-SD,and shorter duration of QRS complex,but higher LV ejection fraction,cardiac index and cardiac output when compared with the His bundle group(P＜0.01).The incidence of adverse events was obviously lower in the left bundle branch group than the His bundle group(6.25％vs 15.69％,P＜0.05).Conclusion Left bundle branch pacing shows significant improvement for cardiac function in elderly HF patients,and can effectively maintain ECG stability and improve LV function.It is a safe and effective cardiac resynchronization therapy.

Pathological interaction between CD4 + T cells and B cells is one of the important mechanisms of systemic autoimmune diseases. Follicular helper T cells (Tfh) and peripheral helper T cells (Tph) are key cells for assisting B cells. Tph cell is a newly discovered helper T cell subset, and their phenotype is PD-1 highCXCR5 -CD4 +. Tph cell and Tfh cell have certain differences in phenotype, function, and site of action. It interacts with B cells, promoting the differentiation of B cells into plasma cells and the production of autoantibodies, as well as promoting the formation of ELS to maintain local inflammation and antibody responses. Tph cells have recently been reported in various autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, Sjogren′s syndrome, and IgG4-related diseases. This review summarizes the progress in peripheral immune response of Tph cells in different systemic autoimmune diseases, aiming to explore the new mechanism of autoantibody production and help to develop new diagnostic and therapeutic targets in the future.

Objective:To investigate the effect of "four-staff co-management" follow-up mode on risk factor control and medium-term prognosis improvement in patients with coronary heart disease after percutaneous coronary intervention (PCI).Methods:This was a intervention study. Patients with coronary heart disease who were admitted to the Xiamen Cardiovascular Hospital of Xiamen University from June 2021 to January 2022 and successfully discharged after PCI were included. According to the different types of follow-up after discharge, patients were divided into the traditional follow-up group and the "four-staff co-management" follow-up group. The "four-staff co-management" follow-up mode means that specialists, specialist managers in third-level A hospitals and general practitioners and health managers in basic hospitals were jointly responsible for post-discharge follow-up of PCI patients. Baseline clinical data were collected. The primary endpoints were the rate of compliance of coronary heart disease risk factor control at 12 months after surgery, the rate of secondary surgery, and the incidence of mid-term major adverse cardiovascular and cerebrovascular events (MACCE). Unplanned secondary PCI included symptom-driven secondary PCI and asymptomatic secondary PCI. MACCE includes myocardial infarction, hospitalization for heart failure, stroke, major bleeding, all-cause death, and composite endpoints including these events.Results:A total of 2 181 patients were enrolled, including 1 097 patients in the traditional follow-up group and 1 084 patients in the "four-staff co-management" follow-up group. At baseline, there were no statistically significant differences in gender, age, discharge diagnosis, co-existing diseases, echocardiographic indexes, and coronary artery lesions between the two groups (all P>0.05). There were no significant differences between the two groups in total PCI stent length, maximum internal diameter of stent, proportion of patients using drug balloon, proportion of patients with a planned second surgery during hospitalization, and discharge with drugs (all P>0.05). Twelve months after PCI, the reduction in HbA1c and low-density lipoprotein cholesterol was greater in the "four-staff co-management " follow-up group than that in the traditional follow-up group (all P<0.05), and the rate of reaching the standard for low-density lipoprotein cholesterol was higher than that in the traditional follow-up group ( P=0.001), but there was no statistical significance between the two groups for blood pressure and blood glucose (all P>0.05). During the follow-up period, the proportion of symptom-driven second operation patients was lower in the "four-staff co-management" follow-up group than that in the traditional follow-up group ( P<0.001), and there was no significant difference in the proportion of asymptomatic second operation patients between the two groups ( P=0.191). The proportion of hospitalized patients with heart failure in the "four-staff co-management" follow-up group was lower than that in the traditional follow-up group ( P=0.029), and there was no significant difference in the proportion of myocardial infarction, cerebral infarction, cerebral hemorrhage, massive hemorrhage, death and complex endpoint events between the two groups (all P>0.05). Conclusion:The "four-staff co-management" follow-up mode can effectively improve the control of risk factors and medium-term prognosis in patients with coronary heart disease after PCI.

Objective:To explore the value of Alberta stroke program early CT Score (ASPECTS) regional net water intake (NWU) based on plain CT in evaluating the neurological outcome of patients with acute large vessel occlusive stroke (ALVOS) after mechanical thrombectomy.Methods:The study was a prospective cross-sectional study. The clinical and imaging data of patients with ALVOS who underwent mechanical thrombectomy in the 904 Hospital of the PLA Joint Service Support Force from June 2022 to June 2024 were prospectively collected. Clinical data analysis included age, gender distribution, National Institutes of Health Stroke Scale (NIHSS) score and Glasgow Coma Scale (GCS) score at admission. All patients underwent plain CT and CT angiography (CTA). Automated processing software quantified ischemic brain edema by calculating ASPECTS and measuring the ASPECTS regional NWU rate (CT-ASPECTS-NWU) based on plain CT. Cerebral collateral circulation was assessed using CTA images. According to the modified Rankin Scale score of patients with mechanical thrombectomy 90 days after the telephone follow-up, 0-2 points were defined as good neurological outcome, and 3-6 points were defined as poor neurological outcome. Independent samples t test, Mann-Whitney U test and χ2 test were used to analyze the differences of clinical and imaging indicators between patients with good and poor neurological outcome, indicators with statistically significant differences were included in multivariate logistic regression analysis to screen out the independent influencing factors that predicted the neurological outcome of patients with ALVOS after mechanical thrombectomys. The efficacy of related indicators to predict neurological outcomes after mechanical thrombectomy in patients with ALVOS was evaluated using receiver operating characteristic (ROC) curve analysis, with the area under the curve (AUC) calculated. Results:A total of 122 patients with ALVOS were included, including 101 patients with good neurological outcome and 21 patients with poor neurological outcome after mechanical thrombectomy. There were statistically significant differences in preoperative GCS score, collateral circulation status, NIHSS score at admission, preoperative ASPECTS and CT-ASPECTS-NWU between patients with good neurological outcome and patients with poor neurological outcome ( P<0.05). Multivariate logistic regression analysis showed that the status of collateral circulation ( OR=3.450, 95% CI 1.158-10.277, P=0.026), preoperative ASPECTS ( OR=0.510, 95% CI 0.274-0.952, P=0.034) and CT-ASPECTS-NWU ( OR=2.131, 95% CI 1.301-3.493, P=0.003) were independent predictors of neurological outcome in patients with ALVOS after mechanical thrombectomy. ROC curve analysis showed that CT-ASPECTS-NWU had the highest predictive value, with an AUC of 0.881, a sensitivity of 85.7%, a specificity of 85.1%, and an optimal cutoff value of 7.55. Conclusion:CT-ASPECTS-NWU demonstrates high diagnostic value in evaluating the neurological outcome of patients with ALVOS after mechanical thrombectomy, and can provide an objective imaging biomarker to guide clinical decision-making.

Recently a patient with biliary fistula after Beger surgery was admitted to Affiliated Hangzhou First People’s Hospital， Westlake University， and successful diagnosis and treatment were achieved through oral choledochoscopy-assisted percutaneous-endoscopic rendezvous technique.

Objective:To explore the diagnostic value of preoperative diffusion weighted imaging (DWI) histogram parameters in the depth of invasion of early rectal cancer.Methods:A total of 180 patients with early rectal cancer admitted to 904th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from August 2020 to August 2024 were selected as the study objects. Patients were divided into intramucosal cancer group ( n=102) and submucosal cancer group ( n=78) according to the depth of tumor invasion. The general data of the two groups were compared. The intraclass correlation coefficient (ICC) was used to analyze the consistency of DWI histogram parameters extracted by the two radiologists, and the differences between the two groups were compared. Receiver operator characteristic (ROC) curve was used to analyze the predictive value of each parameter to the depth of tumor invasion. Multivariate logistic regression was used to analyze the independent influencing factors of invasion depth, and a predictive model was constructed. The ROC curve was drawn to analyze the predictive value of the model for tumor invasion depth, and the Hosmer-Lemeshow test was used to analyze the goodness of fit of the model. Results:There were statistically significant differences in age ( t=8.15, P<0.001), maximum tumor diameter ( χ2=29.29, P<0.001), endoscopic type ( χ2=20.96, P<0.001), histological type ( χ2=24.93, P<0.001) and differentiation degree ( χ2=73.35, P<0.001) between intramucosal cancer group and submucosal cancer group. The mean, variance, skewness, kurtosis, the 1 st, 10 th, 50 th, 90 th, and 99 th percentiles of the histogram parameters of DWI had good consistency (all ICC>0.75). There were statistically significant differences in the mean ( t=5.69, P<0.001), variance ( t=9.75, P<0.001), skewness ( t=10.88, P<0.001), kurtosis ( t=10.06, P<0.001), the 1 st percentile ( t=3.43, P<0.001), 10 th percentile ( t=3.59, P<0.001), 50 th percentile ( t=9.97, P<0.001), 90 th percentile ( t=4.63, P<0.001), and 99 th percentile ( t=2.44, P=0.016) of the DWI histogram parameters between the intramucosal cancer group and the submucosal cancer group. ROC curve analysis results showed that mean [area under the curve (AUC) =0.77], variance (AUC=0.88), skewness (AUC=0.88), kurtosis (AUC=0.78), 50 th percentile (AUC=0.86) and 90 th percentile (AUC=0.82) had certain diagnostic value for submucous cancer. Multivariate analysis showed that age ( OR=9.98, 95% CI: 1.10-90.70, P=0.041), maximum tumor diameter ( OR=7.36, 95% CI: 1.08-50.23, P=0.042), and differentiation degree ( OR=19.88, 95% CI: 1.21-327.92, P=0.037), variance ( OR=16.24, 95% CI: 2.26-116.68, P=0.006), skewness ( OR=21.13, 95% CI: 2.80-59.61, P=0.003), 1 st percentile ( OR=9.78, 95% CI: 1.17-81.76, P=0.035) were independent factors in predicting tumor invasion depth in patients with early rectal cancer. The predictive model based on the above indicators was logit ( P) =1.51+2.30×age+2.00×maximum tumor diameter+2.99×differentiation degree+2.79×variance+3.05×skewness+ 2.28×the 1 st percentile. ROC curve analysis showed that the predictive model had an AUC of 0.97 (95% CI: 0.95-0.99) for judging the occurrence of submucosal cancer in patients with early rectal cancer, the sensitivity was 0.95, and the specificity was 0.88. The Hosmer-Lemeshow test results showed that the goodness of fit of the model was ideal ( P=0.823) . Conclusions:Age, maximum tumor diameter, differentiation degree, variance, skewness, and the 1 st percentile are independent factors in predicting tumor invasion depth in patients with early rectal cancer. The predictive model constructed based on these factors can effectively predict the risk of submucosal cancer in patients with early rectal cancer.
