Objective To explore the indication, surgical technique, and clinical efficacy of the cross bar based on the Nuss procedure in pectus excavatum. Methods The clinical data of patients who underwent cross bar based on the Nuss procedure from August 2023 to August 2024 in Guangdong Provincial People's Hospital were retrospectively analyzed. Results A total of 88 patients including 85 males and 3 females with a mean age of (17.56±5.20) years were enrolled. All operations were performed successfully without intraoperative cardiac injury, pericardial injury or diaphragmatic injury. The mean operation time was (147.65±47.75) min. The mean blood loss was (13.30±9.06) mL. The mean postoperative hospitalization stay was (4.81±1.55) days, without perioperative death. Six (6.82%) patients developed early postoperative complications, including 3 patients of pleural effusion, 1 patient of subcutaneous hematoma, 1 patient of suffocation and 1 patient of bar rotation. The postoperative outcomes were excellent in 71 (80.68%) patients, good in 16 (18.18%) patients and moderate in 1 (1.13%) patient. The excellent and good rate was 98.86%. Conclusion The cross bar technique is safe and convenient, with satisfactory results. It is worth promoting in clinical application.

Objective To investigate the changes of compliance in large arteries and carotid artery intima-media thickness(IMT)in patients with metabolic syndrome.Methods There were 64 patients with metabolic syndrome and 56 age-matched control subjects.Their carotid-femoral pulse wave velocities(C-FPWV)were measured by the Complior SP and their carotid artery IMT were detected by B-mode ultrasound.At the same time their height,weight,waist circumstance,hip girth,blood pressure,blood glucose,blood lipid,BMI and waist to hip ratio(WHR)were measured.Results Compared with the control,the patients with metabolic syndrome had higher C-FPWV(P

With more and more non-affiliated hospitals of universities joining the clinical teaching of infectious diseases,there have been some dilemmas on clinical teaching,such as the shortage of staff,teaching experience,poor lecture art and teaching enthusiasm,textbook lag,the shortage of case teaching abd students'fear of infectious disease etc. Countermeasures such as perfecting the organizational structure,formulating preferential policy,clearing historical mission,increasing students' interest in learning,adding new academic progress,enriching teaching methods,setting up experts'supervision will ensure the effective teaching quality.
