Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

OBJECTIVES: This study aims to explore the current status and risk factors of oral health-related quality of life OHRQoL in patients with mental disorders and provide evidence for effective intervention measures. METHODS: A total of 397 patients diagnosed with mental illness were selected by convenience sampling, and investigation was carried out using general data questionnaire, health literacy in dentistry-14 (HeLD-14), oral health impact profile-14 (OHIP-14), and oral health status checklist. RESULTS: The total score of OHIP-14 in patients with mental disorders was 8(2, 14). The score of HeLD-14 was negatively correlated with the score of OHIP-14 (r=-0.142, P<0.01). The results of multiple linear regression showed that six variables including annual family income, schizophrenia, sweets, frequency of visits to the dentist, dental caries, and missing teeth affected OHRQoL of patients with mental disorders (P<0.05). CONCLUSIONS The poor OHRQoL of psychiatric patients is associated with many factors. Medical personnel should pay attention to their oral health problems and develop targeted oral care programs throughout the course of disease to improve oral health and related quality of life of patients.

Objective:To investigate the feasibility and clinical outcome of estimating the target length of the free margin of the leaflet by diameter of the prosthesis graft used to reconstruct the aortic root during the modified root remodeling procedure.Methods:This is a retrospective case series study. The clinical data of 11 patients with aortic root aneurysm who underwent modified aortic root remodeling procedure with external sub-valvular ring from July 2021 to May 2024 at Department of Cardiovascular Surgery, Fuwai Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College were analyzed. The age of the patients was (42.3±14.4) years (range:23 to 61 years), including 9 males and 2 females. The aortic valve of all patients was tri-leaflet configuration. Marfan syndrome was diagnosed in 3 cases. The diameter of the prosthesis graft was determined according to the Lansac group′s criteria based on the diameter of the aortic annulus, and a graft ring of the same diameter was used as the external sub-valvular ring. The free margin of the leaflet was treated with central plication according to the standard of “target length of free margin of the leaflet=the diameter of the selected graft+3 to 5 mm”. The surgical results and postoperative aortic valve closure function were observed.Results:All 11 patients successfully completed the operation without in-hospital death or complications. The graft with a diameter of 28 mm were used in 7 cases, 26 mm in 3 cases, and 30 mm in 1 case. 4 patients required central plication of the free margin of 3 leaflets, 2 patients required treatment of 2 leaflets, 3 patients required treatment of 1 leaflet, and 2 patients did not need treatment of the free margin of the leaflets. The functional status of aortic valve closure was significantly improved in all patients after surgery, and the degree of residual aortic regurgitation was not more than mild. After reconstruction of the aortic root, the measured effective height was (8.8±1.3) mm (range:7 to 11 mm) and the measured coaptation length was (5.2±0.9) mm (range:4 to 7 mm). All patients were re-examined 3 months after surgery. Echocardiography showed that the degree of aortic regurgitation was mild or lower, and the left ventricular end-diastolic diameter was (49.4±6.1) mm (range: 36 to 56 mm), which was smaller than that before the operation ((58.5±7.0) mm (range: 47 to 72 mm)). Eight patients were followed up for more than 6 months, and 5 patients were followed up for more than 1 year. The degree of aortic regurgitation in these patients was mild or below.Conclusions:The method based on the diameter of the selected prosthesis graft to deal with the length of the free margin of the leaflet can be effectively used in the modified aortic root remodeling procedure with external sub-valvular ring. The early postoperative results are satisfactory .

Objective To elucidate the influence of two procedures aortic root remodeling using a straight tubular artificial vessel while preserving the aortic valve and the Florida sleeve procedure on the biomechanics of the aortic root.Methods Five finite element models of the aortic root were reconstructed using computed tomography angiography images,including two cases of aortic root remodeling(A1 and A2),two cases of the Florida sleeve procedure(B1 and B2),and one control group without aortic root pathology(C).Numerical simulations were performed to obtain the blood flow and pressure distribution result to assess the differences in the hemodynamics of the aortic root.Results There were no significant differences in the peak systolic velocity between the two procedures and the control.However,the flow velocity after aortic root remodeling was smoother,similar to the model of the control group,with a more stable average aortic pressure and wall shear stress.In the Florida sleeve procedure,high-speed blood flow affected the vessel wall,leading to various degrees of wall shear stress and pressure concentrations along the aortic wall.Conclusions After aortic root replacement with valve preservation,blood flow patterns in the reconstructed aortic root depended on postoperative changes in sinus geometry.Both surgical procedures showed favorable blood flow patterns;however,the flow pattern after aortic root remodeling was more stable than that after the Florida sleeve procedure.

Objective:To understand the current state of renal replacement therapy (RRT) in intensive care unit (ICU) of Tianjin public hospital, and to provide scientific evidence and direction for homogenized management and overall level improvement of RRT in Tianjin.Methods:The questionnaires were distributed to the chief or key staff of 33 ICUs from 32 public hospitals in Tianjin by clinical quality control center for critical care medicine of Tianjin and ICU of Tianjin Third Central Hospital. The RRT data of ICUs from January 2020 to December 2021 was collected, including the type and size of ICU, the number of patients undergoing RRT, reasons for initiating RRT, the RRT modes, the anticoagulation and the complications of RRT and so on.Results:A total of 33 valid questionnaires were obtained, with a recovery rate of 100%. The result showed that there were 38 803 patients admitted to the selected ICUs during investigation, and 5 456 of them (14.06%) received RRT. In most ICUs, the reasons of initiating RRT were renal failure, sepsis and volume overload. The mode of RRT was mainly continuous venovenous hemofiltration (CVVH), which was followed by continuous venovenous hemodiafiltration (CVVHDF). Carbonate replacement fluid was the first choice. Heparin was the dominant anticoagulant, and there was an increasing trend in the use of citrate anticoagulation simultaneously. However, heparin-free anticoagulation used mostly in bleeding patients. Overall, the RRT modes and anticoagulation methods were single. Thrombosis was the main iatrogenic factor interrupting RRT in most ICUs, and also the reasons for complications related to catheter or circulation pipeline. It still showed an ineffective anticoagulation of RRT even after increasing the dosage of anticoagulants.Conclusions:RRT is an important organ support method in ICU, which has been widely carried out in ICUs of Tianjin and continues to expand. Despite the positive performance, it still needs to be improved and standarized in some aspects, such as the diversification of RRT modes, anticoagulation, and the complication prevention.

The professional title evaluation of health professionals needs to highlight the clinical performance and actual contribution, and make full use of the information system of medical and health institutions to collect relevant data as an important basis for such evaluation.Based on this, the project team innovatively developed a " clinical work data extraction system" , to extract and calculate the performance indexes of clinicians using data from homepages of medical records. Meanwhile, the team established a reference scale based on the data in the hospital quality monitoring system; developed a " health workers evaluation data platform" , visually presenting the comparison results between the clinical work performance evaluation data of a clinician, and the reference scale and the data of other applicants. In the 2021 annual evaluation of senior professional titles among some medical institutions directly under the National Health Commission and such provinces as Sichuan, Shandong and Chongqing, this method was used to extract homepage data of medical records of 7 833 applicants from 39 medical specialties in 1 416 medical institutions, and finally 6 093 people (77.79%) completed the calculation of clinical work evaluation index data. The initial application results showed that the evaluation of senior clinicians′ professional competence based on homepage data of the medical record was feasible in the senior professional title evaluation of various medical institutions at all levels equipped with the electronic medical record database system, and could effectively present the performance level and actual contribution of the applicant.

Objective    To assess outcomes of transcatheter aortic valve replacement (TAVR) for pure native aortic valve regurgitation. Methods    A total of 129 patients underwent transfemoral TAVR in Fuwai Hospital from May 2019 to October 2020 were retrospectively analyzed. There were 83 males and 46 females with an average age of 72.26±8.97 years. The patients were divided into a pure native aortic valve regurgitation group (17 patients) and an aortic valve stenosis group (112 patients). Results    The incidence of valve in valve was higher in the pure native aortic valve regurgitation group (47.0% vs. 16.1%, P<0.01). There was no statistical difference between the two groups in conversion to surgery, intraoperative use of extracorporeal circulation, intraoperative left ventricular rupture, postoperative use of extracorporeal membrane oxygenation (ECMO), peripheral vascular complications, disabled stroke, death, or pacemaker implantation. There was no statistical difference in the diameter of annulus (25.75±2.21 mm vs. 24.70±2.90 mm, P=0.068) or diameter of outflow tract (25.82±3.75 mm vs. 25.37±3.92 mm, P=0.514) between the pure native aortic valve regurgitation group and the aortic valve stenosis group. Conclusion    Transfemoral TAVR is a feasible method for patients with pure native aortic valve regurgitation. The diameter of annulus plane, the diameter of outflow tract and the shape of outflow tract should be evaluated.

Objective: To investigate theperiodic changes in onset of aortic dissection. Methods: The clinical data of 1 121 patients with acute aortic dissection from Hebei province, treated at Fuwai hospital from January 1, 2010 to December 31, 2016, were collected and analyzed retrospectively. The regularity for the onset of aortic dissection was analyzed according to daytime (1:00 to 6:00, 7:00 to 12:00, 13:00 to 18:00, and 19:00 to 24:00), weekday, month, and quarter. Meanwhile,the differences in various type of aortic dissection patient were also compared. Results: The patients were (51.4±12.0) years old,77.88% (873 cases)were male and 69.05% (774 cases) were type A aortic dissection.The peak period for the onset of the disease in a day was from 13:00 to 18:00 (401 cases. 35.77%),and disease onset was less frequent from 1:00 to 6:00 (196 cases, 17.48%).The peak weekday of disease onset was Monday (173 cases, 15.43%) , and disease onset was less frequent on Friday (153 cases, 13.65%) . The peak month of disease onset was January (135 cases, 12.04%), and disease onset was less frequent in July(54 cases, 4.82%). The peak season of disease onset was winter (349 cases, 31.13%), and disease onset was less frequent in summer (184 cases, 16.41%). Number of disease onset was similar between ≥65 years old and<65 years old groups, with or without hypertension groups, with or without Marfan syndrome groups at different periods of a day, each weekday, and seasons(all P>0.05). Conclusion There are periodic changes in the onset of acute aortic dissection,which is higher in winter than in summer, higher in the afternoon than in the morning.

Objective: To investigate the technical method for harvesting and application of the descending branch of the lateral circumflex femoral artery (DBLCFA) in the coronary artery bypass grafting (CABG) operation. Methods: Between December 2016 and April 2017, 19 patients were arranged to use DBLCFA and got CT angiography (CTA) of pelvic and femoral arteries pre-operative at Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Finally, DBLCFA was harvested in 16 patients (including 2 female patients, with a mean age of (47.4±8.5) years) through the anterior thigh incision (13 cases on the left side, 3 cases on the right side). The CABG operations were performed under the cardiopulmonary bypass support (in 10 cases) or under the beating heart condition (in 6 cases), and the DBLCFA conduit was used combining with bilateral internal thoracic artery (in 12 cases), radial artery (in 7 cases) and saphenpous vein (in 3 cases). Results: Due to anatomical variations such as short length and anomalous branch, or due to silent atherosclerosis stenosis of femoral artery, DBLCFA in 3 patients was considered inappropriate for use and was not harvested after CTA examination. In another 16 patients, DBLCFA was safely and quickly harvested and successfully used. On average, 3.4±0.6 anastomosis was built up in CBAG, no adverse effects were exhibited. The length of the harvested DBLCFA was (10.3±1.8) cm, with average lumen diameter of (1.9±0.5) mm. DBLCFA was used as free graft in 15 patients (7 to the first diagonal branch, 6 to the ramus intermedius branch, 1 to the left anterior descending branch and 1 to the second obtuse marginal branch). In 1 patient, the DBLCFA was firstly implanted end-to-side to the internal thoracic artery as a "Y" type composite graft, and then anastomosed to the third obtuse marginal branch. Conclusions The descending branch of the lateral circumflex femoral artery is an option conduit in CABG. It can be harvested easily and safely. However, pre-operative CTA examination is necessary to exclude the variation and appropriate strategy for graft establishment should be considered during the operation.
