Objective:The New Medicine is an emerging field of medicine that integrates traditional medicine with artificial intelligence (AI) and big data. Under the background of New Medicine, this study aims to explore the application of AI in medical higher education, investigate the development status of universities in this field, and propose targeted optimization suggestions, with the purpose of providing a reference for improving medical education quality and cultivating outstanding doctors.Methods:In each of the six administrative divisions of China, a key university and a general university were randomly selected as research objects. Two researchers with teaching experience conducted a search on the official websites of these universities, using "artificial intelligence" as the keyword. They retrieved publicly available information from January 1, 2020 to December 18, 2024, and screened for the content related to medical teaching. The data of these universities were organized and summarized based on five categories: courses, training, teaching platforms, conferences, and lectures.Results:After a series of searches, screenings, and summaries, the researchers identified a total of 58 AI-related projects applied in medical education across the five areas of courses, training, teaching platforms, conferences, and lectures. Of these, 34 projects came from six key universities, and 24 projects were from six general universities. Key universities have demonstrated the advantages in multidisciplinary integration, technology-driven approaches, and international perspectives through systematic curriculum design (e.g., multi-level AI course at Zhejiang University), intelligent teaching assistant tools (e.g., "Brainiac Buddy" at Peking University), and international visiting programs (e.g., AI Summer Visting Program at Zhejiang University). General universities implemented practices such as knowledge graphs, 5G smart platforms, and virtual simulation courses (e.g., "medical image processing" course at Southwest Medical University), achieving multi-level capability enhancement from basic medical education to health management skill education, as well as significant outcomes in "health-centered" and "education model innovation".Conclusions:AI-powered medical education has shown great innovation potential in Chinese universities, with unique development characteristics at different universities.

Objective:To investigate the effectiveness of autologous bilateral auricular concha cartilage-modified scaffolds in rhinoplasty.Methods:Retrospectively, 219 patients aged (28.7±5.5) years, 8 males and 211 females, who underwent rhinoplasty at the An Beili Medical Beauty Clinic in Shimen County, Changde City, Hunan Province, from January 2020 to January 2022, were included. Every patient consented to apply modified scaffolds of autologous bilateral auricular concha cartilage for rhinoplasty; 157 received primary rhinoplasty and 62 underwent secondary rhinoplasty repair. To construct the nasal tip morphology, bilateral auricular concha cartilage was excised, symmetrically divided and aligned sutures to form nasal columellar support grafts and anti-tip rotation grafts. Thermoplastic splints and tape were used to fix the dorsum of the nose, and tumescent sponges to fill the nasal cavity. Prophylactic antibiotics were routinely administered after surgery for 48 hours, and depending on how well the wound healed, the stitches were taken out 8 to 10 days later.Results:A local infiltration anesthetic was used throughout the procedure on all 219 patients. The majority of patients had a willow-shaped prosthesis constructed for the dorsum of their noses. A total of 145 patients had silicone prostheses, and 74 patients had expanded polytetrafluoroethylene prostheses. The mean operating duration was (72.92±13.26) minutes. Within 8 to 10 days after surgery, all patients had their sutures taken out, the surgical incisions healed properly, and all 219 patients were satisfied with their nasal appearance in the immediate postoperative period. The nasal tip height was elevated by an average of (4.7±0.5) mm, and the nasal length was extended by an average of (5.7±0.6) mm over the mean follow-up of (14±2) months. Among 219 patients, 96.8% (212/219) of the patients expressed satisfaction with the form of their noses. The postoperative nasal shape, with its naturally elevated nasal dorsum, rounded tip profile, and pronounced tip-defining point, complied with the natural aesthetic criteria. Three patients experienced a chronic nasal infection following surgery, while the remaining four experienced postoperative tip-down rotation.Conclusions:Using bilateral auricular concha cartilage, the tip cartilage modified scaffolding provides a better nasal appearance and tip mobility after rhinoplasty for the patients.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.
