Objective:To investigate the occurrence and influencing factors of oral frailty among the elderly in China.Methods:General information questionnaire,Oral Frailty Scale,Sarcopenia Screening Questionnaire(SARC-F),Social Network Scale-6(LSNS-6)and Subjective Cognitive Decline Questionnaire(SCD-Q9)were used to conduct a survey in Anhui Province.A survey was conducted among 3 063 elderly people to analyze their current status and influencing factors related to oral frailty.Results:The incidence of oral frailty among the elderly in Anhui Province was 46.82％(1434/3063).Binary logistic regression analysis showed sarcopenia(OR=8.742,95％CI:7.156-10.679),social isolation(OR=1.601,95％CI:1.313-1.953),and subjective cogni-tive decline(OR=2.424,95％CI:1.905-3.085),90 years old and above(OR=2.261,95％CI:1.304-3.922)and having disability(OR=1.341,95％CI:1.040～1.729)are risk factors for oral frailty in the elderly in Anhui Province.Conclusion:The incidence of oral frailty is high among the elderly in Anhui Province.Risk factors for oral frailty include sarcopenia,social isolation,subjective cognitive decline,advanced age,and disability.

Objective:To summarize the early clinical outcomes of aortic valve replacement(AVR) using the Perceval sutureless aortic valve.Methods:This retrospective study included 50 patients who underwent AVR with the Perceval sutureless prostheses at Beijing Anzhen Hospital between June 2023 and January 2025. Surgical parameters, early clinical outcomes, valve function, and hemodynamic performance were evaluated to summarize clinical effectiveness.Results:The mean age of patients was(63.5±9.1) years, predominantly female(36/50). Severe aortic stenosis was present in 43 cases(86.0%). A preoperative aortic annulus dimension of 20.0(19.0, 21.0) mm measured in both anteroposterior and transverse diameters. Preoperative peak transvalvular gradient was(92.7±31.0)mmHg(1 mmHg=0.133 kPa), with a mean gradient of (58.0±21.2) mmHg. All procedures were successfully completed using the Perceval sutureless prostheses. Isolated AVR was performed in 20 patients(40.0%), with cardiopulmonary bypass and aortic cross-clamp times of 75.0(50.5, 99.5) min and 50.5(29.5, 71.5) min, respectively. Postoperative transesophageal echocardiography revealed an immediate reduction in the peak transvalvular gradient to 11.0(8.0, 18.0) mmHg, significantly lower compared to preoperative measurements( P<0.001). Two cases of paravalvular leakage and one case requiring permanent pacemaker implantation were reported postoperatively. All patients completed the 3-month follow-up, with one death during the follow-up period; the remaining patients exhibited normal prosthetic valve function without major adverse cardiovascular events. Significant postoperative reductions were observed in left ventricular end-diastolic diameter(45.8 mm vs. 43.2 mm, P=0.003) and left atrial diameter(53.9 mm vs. 44.6 mm, P<0.001) compared with baseline. Conclusion:AVR using the Perceval sutureless prostheses demonstrated safe and effective early clinical outcomes with excellent hemodynamic performance and low incidence of postoperative paravalvular leakage and permanent pacemaker implantation. The sutureless technique represents a viable alternative strategy, particularly advantageous for patients with small aortic annuli or complex surgical conditions, warranting broader clinical adoption.

Objective:To investigate the effects of different levels of ophthalmic surgical stimulation on blood glucose in patients with type 2 diabetes mellitus(T2DM).Methods:From Mar to Oct 2021,236 patients with T2DM who underwent ophthalmic surgery in our hospital were enrolled,including 71 cases of secondary surgery,89 cases of tertiary surgery,and 76 cases of quaternary surgery.According to the operation time,the 236 patients were divided into groups A(＜60 min),B(60-120 min)and C(＞120 min).The preoperative and postoperative blood glucose levels were compared in patients with different levels of surgery,and in groups A,B and C.Results:The postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery,and it was higher than that before surgery in quaternary surgery(P＜0.05).The fluctuation value of blood glucose in secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In groups A,B and C,the postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery(P＜0.05).In group A,there was no significant difference in the blood glucose before and after surgery in quaternary surgery(P＞0.05),and in groups B and C,the postoperative blood glucose was higher than that before surgery in quaternary surgery(P＜0.05).In group A,there was no difference in the fluctuation value of blood glucose at different levels of surgery(P＞0.05).In group B,the fluctuation value of blood glucose in patients with secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In group C,the fluctuation value of blood glucose in patients with tertiary and quaternary surgery was higher than that in patients with secondary surgery(P＜0.05).Conclusions:For ophthalmic surgery patients with T2DM,the postoperative blood glucose values of patients undergoing secondary and tertiary surgery generally show a downward trend,while the postoperative blood glucose value of patients undergoing quaternary surgery generally shows an upward trend.It is suggested that clinical workers should actively manage the perioperative blood glucose of patients with high-level surgery.

Objective To develop a deep learning network based on attention mechanism to identify the number of the vertical man-dibular third molar(MTM)roots(single or double)on panoramic radiographs in an automatic way.Methods The sample consisted of 1 045 patients with 1 642 MTMs on paired panoramic radiographs and Cone-beam computed tomography(CBCT)and were randomly grouped into the training(80%),the validation(10%),and the test(10%).The evaluation of CBCT was defined as the ground truth.A deep learning network based on attention mechanism,which was named as RN-MTMnet,was trained to judge if the MTM on pano-ramic radiographs had one or two roots.Diagnostic performance was evaluated by accuracy,sensitivity,specificity,and positive predict value(PPV),and the receiver operating characteristic(ROC)curve with the area under the ROC curve(AUC).Its diagnostic perform-ance was compared with dentists'diagnosis,Faster-RCNN,CenterNet,and SSD using evaluation metrics.Results On CBCT images,single-rooted MTM was observed on 336(20.46%)sides,while two-rooted MTM was 1 306(79.54%).The RN-MTMnet achieved an accuracy of 0.888,a sensitivity of 0.885,a specificity of 0.903,a PPV of 0.976,and the AUC value of 0.90.Conclusion RN-MTM-net is developed as a novel,robust and accurate method for detecting the numberof MTM roots on panoramic radiographs.

Objective:This study aims to explore the survival advantages of different maintenance strategies for MCL.Methods:Clinical data of 693 newly diagnosed MCL patients in multi-centers admitted from April 1999 to December 2019 were collected. 309 cases received maintenance treatment. The characteristics of patients in different maintenance treatment groups were summarized and Kaplan-Meier survival and prognosis analysis were conducted.Results:The overall 3-year and 5-year progression-free survival (PFS) rates were (73.5±2.9) % and (53.6±4.3) %, respectively. The 3-year and 5-year overall survival (OS) rates were (94.2±1.5) % and (82.7±3.2) %, respectively. The clinical features of different maintenance treatment groups were generally consistent. The 3-year PFS rates of rituximab maintenance, lenalidomide maintenance, BTK inhibitor maintenance and dual-drug maintenance were (70.4±4.1) %, (69.1±7.6) %, (86.9±5.0) %, and (80.4±5.1) %, respectively. Corresponding 3-year OS rates were (92.9±2.4) %, (97.3±2.7) %, (97.9±2.1) %, and (95.3±2.7) %, respectively. There were no significant difference in different groups ( P=0.632, 0.313). Survival analysis identified the MCL International Prognostic Index (MIPI) high-risk group and achieving complete remission before maintenance treatment as independent risk factors for PFS. The MIPI high-risk group, high-dose cytarabine application, treatment lines, and early disease progression (POD24) emerged as independent risk factors for OS. Conclusion:Comparing the different maintenance strategies of MCL, the result showed that BTK inhibitors (BTKi) maintenance demonstrated preliminary advantages in survival. Meanwhile, high-risk group according to MIPI and incomplete remission before maintenance treatment were significant factors related to disease progression.

Objective     To provide experience for clinical diagnosis and treatment through exploring the perioperative characteristics and short-term treatment outcomes of adult cardiac surgery in patients with prior coronavirus disease-2019 (COVID-19). Methods    A retrospective analysis was performed on patients undergoing coronary artery bypass grafting (CABG) or valve surgery in the Department of Cardiac Surgery of Beijing Anzhen Hospital from December 26, 2022 to December 31, 2022, and previously diagnosed with COVID-19 before surgery. Results    Finally 108 patients were collected, including 81 males and 27 females, with an average age of 60.73±8.66 years. Two (1.9%) patients received emergency surgery, and the others received elective surgery. The 86.1% of patients had been vaccinated, and the duration of COVID-19 was 5.0 (4.0, 7.0) days. The time from COVID-19 to operation was 15.0 (12.0, 17.8) days. Eighty-nine patients received CABG, of which off-pump CABG was dominant (92.1%). Nineteen patients received valve surgery. The rate of delayed extubation of ventilator was 17.6%. The ICU stay was 21.0 (17.3, 24.0) hours, and the postoperative hospital stay was 7.0 (6.0, 8.0) days. Three (2.8%) patients were treated with intra-aortic balloon  pump (IABP), one (0.9%) patient was treated with extracorporeal membrane oxygenation (ECMO), one (0.9%) patient was treated with continuous renal replacement therapy (CRRT) due to acute renal insufficiency, three (2.8%) patients were treated with temporary pacemaker, and one (0.9%) patient underwent rethoracotomy. In terms of postoperative complications, the incidence of cerebrovascular accident, acute renal insufficiency, gastrointestinal bleeding and septicemia was 0.9%, respectively, and the incidence of acute heart failure, lung infection, and liver insufficiency was 1.9%, respectively. All patients recovered and were discharged from hospital, and no in-hospital death occurred. Conclusion     The utilization rate of postoperative IABP, ECMO, CRRT, temporary pacemaker and the incidence of serious complications in patients with prior COVID-19 are not higher than those of normal patients, and the short-term treatment outcome is good.

Rheumatic mitral stenosis is one of the most common cardiac valvulopathies in our country, which is relatively rare in European and American countries. Medical therapy is reserved mainly for the treatment of complications, which can not fundamentally change the valve structure. Only surgical treatments can correct these valve lesions, including closed mitral commissurotomy, percutaneous balloon mitral valvuloplasty, mitral valve repair under direct vision and mitral valve replacement. Numerous studies demonstrate that valve repair provides better long-term results, though it occupies a low proportion clinically. This article reviewed domestic and foreign literature concerning surgical treatments for patients with rheumatic mitral stenosis to provide some reference for the peers.

Objective:This study was performed to assess the effect of glycemic control on atrial fibrillation recurrence rates after heart surgery concomitant with Cox-Maze Ⅳ ablation.Methods:A retrospective analysis was performed on 317 diabetic patients with atrial fibrillation who underwent cardiac surgery combined with Cox-Maze Ⅳ ablation in our hospital from May 2016 to February 2020. The patients were followed up for(37.7±27.7) months, and the data of atrial fibrillation recurrence and clinical outcome were collected and compared. The limited cubic spline model was used to analyze the dose-relationship between HbA1c level and the recurrence of atrial fibrillation. The univariate and multivariate Cox proportional regression analysis was used to explore the risk factors of recurrent atrial fibrillation after Cox-Maze Ⅳ ablation. Results:Higher glycated hemoglobin(HbA1c) at the time of ablation was associated with higher post-ablation recurrence rates. The cumulative survival freedom from atrial fibrillation recurrence for patients with HbA1c ≥7.4% at time of operation at 12, 24, 36 and 48 months were 96.3%、75.8%、52.7% and 35.7%, respectively( P<0.001). Besides, the rates of all-cause mortality, cardiac mortality and rehospitalization were significantly lower in patients with HbA1c<7.4%(1.7% vs. 6.3%, P=0.03; 1.1% vs. 5.6%, P=0.02 and 5.7% vs. 20.4%, P=0.01). The multivariate Cox regression model showed that HbA1c was an independent risk factor for atrial fibrillation recurrence( P<0.05). Conclusion:Higher preoperative HbA1c levels were associated with increased recurrence of atrial fibrillation and adverse clinical outcomes in patients undergoing cardiac surgery combined with Cox-Maze Ⅳ ablation.
