ObjectiveTo analyze the drug resistance and the molecular typing characteristics through pulsed field gel electrophoresis (PFGE) of Campylobacter spp. isolated from patients with infectious diarrhea in Baoshan District of Shanghai, and to provide a basis for Campylobacter spp. prevention and control and clinical medication. MethodsCampylobacter spp. was isolated, cultured and identified from stool samples of diarrheal patients collected from medical institutions at two monitoring sites in Baoshan District from 2019 to 2022. Antimicrobial susceptibility testing for 12 antibiotics was conducted on the isolated Campylobacter jejuni (C. jejuni) and Campylobacter. Coli (C. coli), and molecular typing was performed using PFGE. ResultsA total of 179 strains of Campylobacter spp. were isolated from 1 786 samples of diarrheal patients, with a positive rate of 10.02%. The highest resistance rate of C. jejuni was to ciprofloxacin (98.63%), followed by tetracycline (97.26%) and nalidixic acid (89.73%). C. coli was completely resistant to ciprofloxacin and nalidixic acid (100.00%), followed by tetracycline (90.91%). The multidrug resistance rates of C. jejuni and C. coli were 89.73% and 100.00%, respectively. 142 strains of C. jejuni produced 122 PFGE bands, while 33 strains of C. coli produced 33 PFGE bands, and the distribution of the bands was relatively dispersed. ConclusionFrom 2019 to 2022, the detection rate of Campylobacter in diarrheal patients was relatively high in Baoshan District of Shanghai, the multidrug resistance rate of Campylobacter isolates from diarrheal patients was relatively serious, in addition, the drug resistance pattern was complex, and the PFGE band pattern displayed a polymorphic distribution.

With the rapid development of artificial intelligence （AI） technology， more and more integrated elderly care and medical service data have been collected and developed recently. However， it also has caused corresponding ethical risks in terms of privacy security such as data leakage and abuse， as well as data standardized management such as data disclosure and circulation. Based on these， this paper explored the sources of problems associated with the integrated elderly care and medical service data from the aspects of policy objectives， the elderly care and medical service industry， and application scenarios. Grounded in the ethical framework for data application of integrated elderly care and medical service， this paper discussed the policy ethics in integrated elderly care and medical service policies and AI technology application， the data ethics in the collection and sharing development of integrated elderly care and medical service data， and the ethical risks and challenges in the big model of integrated elderly care and medical service data and the allocation of computing resources. Furthermore， it explored countermeasures and suggestions for addressing ethical issues in data application of the integrated elderly care and medical service from three aspects， including data utilization， rights protection， and responsibility guarantee， with a view to providing references for promoting the standardized application of AI technology in integrated elderly care and medical service.

Objective To investigate the safety of totally thoracoscopic mitral valve reoperation with hypothermia-induced ventricular fibrillation arrest in elderly patients.Methods Clinical data of 108 elderly patients undergoing redo mitral valve surgery in our department from January 2008 to October 2024 were retrospectively collected,and according to surgical approach,they were di-vided into a totally thoracoscopic group(totally thoracoscopy with hypothermia-induced ventricu-lar fibrillation arrest,46 cases)and a median sternotomy group(cardiac arrest after median ster-notomy,62 cases).Their perioperative data were compared between the two groups.Results There were no statistical differences in baseline data between the two groups(P＞0.05).When compared with the median sternotomy group,the totally endoscopic group had significantly longer cardiopulmonary bypass time and higher mitral valvuloplasty rate and postoperative LVEF value,but obviously reduced lowest intraoperative temperature,lower blood transfusion rate,less vol-ume of suspended red blood cells transfused,decreased troponin T level 1 d postoperatively,shor-ter duration of mechanical ventilation and lengths of ICU stay and postoperative hospital stay,and less postoperative drainage volume(P＜0.05,P＜0.01).But there were no statistical differences between the two groups in terms of postoperative stroke(6.52％vs 3.23％,P=0.420)or in-hospital death(6.52％vs 6.45％,P=0.988).Conclusions Totally thoracoscopy with hypothermi-a-induced ventricular fibrillation arrest is safe and reliable for the elderly patients who need to receive mitral valve reoperation.

Objective:To examine the therapeutic strategy and its impacting factors by analyzing the perioperative outcomes of total thoracoscopic repeat mitral valve surgery under moderate hypothermia-induced ventricular fibrillation with cardiopulmonary bypass.Methods:This study is a retrospective case series. Totally 63 patients who underwent repeat mitral valve surgery by the same surgeon from January 2021 to December 2023 in Department of Cardiovascular Surgery, the First Medical Center of People′s Liberation Army General Hospital were retrospectively enrolled. There were 28 males and 35 females with an age of (58.3±15.9) years (range: 13 to 84 years). Surgery was performed using a totally thoracoscopic approach under moderate hypothermia-induced ventricular fibrillation. Mitral valvuloplasty was completed in 32 cases and mitral valve replacement in 31 cases. Preoperative baseline data and perioperative outcomes of the patients were collected and Logistic regression was used to analyze independent influencing factors of premature ventricular contractions in the early postoperative period.Results:The intraoperative cardiopulmonary bypass time was (191.5±50.9) minutes (range: 95 to 286 minutes), and the hypothermic ventricular fibrillation time was (99.0±39.8) minutes (range: 34 to 203 minutes). The anal temperature before the start of cardiopulmonary bypass was (36.3±0.5) ℃ (range: 35.2 to 38.0 ℃), the lowest intraoperative anal temperature was (27.3±1.3) ℃(range: 23.7 to 30.1 ℃), and the anal temperature at the time of the cessation of cardiopulmonary bypass was (36.3±0.4) ℃ (range: 35.2 to 37.0 ℃), and excessive rewarming was observed in 33 cases. Six cases applied the artificial heart assist device. Seventeen cases developed premature ventricular contractions in the early postoperative period. Two cases developed neurologic complications. Five cases developed respiratory complications. One case developed urological systemic complications. Six cases were mechanically ventilated for more than 3 days, and the duration of ICU stay in 16 cases was more than 3 days and the postoperative discharge time of ( M(IQR)) 8.0 (3.5) days (range: 3 to 26 days). Two cases died or were discharged voluntarily. Logistic regression results showed that persistent preoperative atrial fibrillation ( OR=11.424, 95% CI: 1.477 to 144.564, P=0.033) and excessive rewarming ( OR=15.249, 95% CI: 1.357 to 279.571, P=0.038) were independent risk factors for the appearance of premature ventricular contractions in the early postoperative period. Conclusions:The technique of total thoracoscopic surgery under induced moderate hypothermic ventricular fibrillation with cardiopulmonary bypass could be applied to repeated mitral valve surgeries with less trauma and faster recovery. Persistent preoperative atrial fibrillation and excessive rewarming are independent risk factors for the occurrence of premature ventricular contractions in the early postoperative period.

Objective    To evaluate the early and mid-term results of robot-assisted coronary artery bypass grafting (RACAB) in the treatment of multi-vessel coronary artery disease (MV-CAD). Methods     Patients with MV-CAD who underwent RACAB from April 2018 to December 2021 in our hospital were included. Patients who underwent hybrid coronary revascularization (HCR) which combined RACAB with percutaneous coronary intervention were allocated to a HCR-RACAB group, and patients who underwent multi-vessel RACAB were allocated to a MV-RACAB group. Perioperative and follow-up data were collected and compared between the two groups. Results     A total of 102 patients were included, including 81 males and 21 females with a mean age of 61.7±10.8 years. Two (2.0%) patients were transferred to conventional CABG due to sudden ventricular fibrillation and pleura adhesion. In the remaining 100 patients who underwent RACAB, 100 left internal mammary arteries (LIMA) and 46 right internal mammary arteries (RIMA) were harvested with a 100.0% success rate. Besides, all patients undergoing RACAB achieved LIMA/RIMA-left anterior descending branch reconstruction, with an average number of 2.5±0.6 target vessels revascularized by stent or graft. One patient had perioperative myocardial infarction with an outcome of death. The incidence of major perioperative adverse events was 1.0%. There was no perioperative stroke or re-sternotomy for hemostasis. The mean follow-up time was 28.2 months, with a follow-up rate of 99.0% and an overall major adverse cardiac and cerebrovascular event (MACCE) rate of 7.0%, including 3 all-cause deaths (3.0%), 2 strokes (2.0%) and 3 re-revascularizations (3.0%). The HCR-RACAB group had fewer red blood cell transfusion (P=0.030) and intraoperative blood loss (P=0.037) compared with the MV-RACAB group, and there was no statistical difference in the incidence of major perioperative adverse events or MACCE between the two groups during the follow-up period (P>0.05). Conclusion    RACAB can be safely applied in the treatment of MV-CAD with good early and mid-term outcomes. High-quality harvesting of LIMA/RIMA and aortic no-touch technique are crucial to achieve these results.
