Objective To explore the application of artificial intelligence (AI) in the standardized training of thoracic surgery residents, specifically in enhancing clinical skills and anatomical understanding through AI-assisted lung nodule identification and lung segment anatomy teaching. Methods Thoracic surgery residents undergoing standardized training at Peking Union Medical College Hospital from September 2023 to September 2024 were selected. They were randomly assigned to a trial group and a control group using a random number table. The trial group used AI-assisted three-dimensional reconstruction technology for lung nodule identification, while the control group used conventional chest CT images. After basic teaching and self-practice, the ability to identify lung nodules on the same patient CT images was evaluated, and feedback was collected through questionnaires. Results A total of 72 residents participated in the study, including 30 (41.7%) males and 42 (58.3%) females, with an average age of (24.0±3.0) years. The trial group showed significantly better overall diagnostic accuracy for lung nodules (91.9% vs. 73.3%) and lung segment identification (100.0% vs. 83.70%) compared to the control group, and the reading time was significantly shorter [ (118.5±10.5) s vs. (332.1±20.2) s, P<0.01]. Questionnaire results indicated that 94.4% of the residents had a positive attitude toward AI technology, and 91.7% believed that it improved diagnostic accuracy. Conclusion AI-assisted teaching significantly improves thoracic surgery residents’ ability to read images and clinical thinking, providing a new direction for the reform of standardized training.

Objective: To establish a "regular blood donor red blood cell gene database"(hereafter referred to as the "database") by applying molecular biology techniques for red blood cell antigens genotyping and utilizing information technology software, and to determine the significance and application value of this "database" in precise red blood cell transfusion. Methods: Fifteen antigens [C, c, E, e, M, N, S, s, Fy (a), Fy (b), Jk (a), Jk (b), Le (a), Le (b), P1] across six blood group systems (RHCE, MNS, FY, JK, Lewis and P1PK) were detected among 9 426 regular blood donors using the TaqMan-MGB method combined with an improved U-shaped microplate approach. With the assistance of information technology software, the "database" was integrated into the overall inventory management system of the blood supply chain. This enabled comprehensive management of regular blood donor and patient information, test results, specific antigen screening for regular blood donors, graded antigen matching between donors and patients, and rare blood type donor records. Results: The TaqMan-MGB method successfully detected paired antigens (C/c, E/e, M/N, S/s, Fy
/Fy
, Jk
/Jk
) within a single reaction well using a standardized PCR amplification protocol. This method provided a reliable testing solution for clinical institutions and empowered blood collection and supply organizations with high-throughput screening capabilities. In the blood supply chain, genotyped red blood cells accounted for 13.2% (721/5 462 U) of the total inventory, with 95.34% (348/365) originating from donors who donated two units of blood. Moreover, the “database” fulfilled 94.06% (443/471 U) of compatible transfusion requirements from medical institutions and effectively managed rare blood type donors. Conclusion: The establishment of the "database" facilitated the transition of blood compatibility testing from traditional serological methods to molecular biology-based gold standard techniques, significantly advancing the implementation of precise transfusion strategies based on multi-antigen matching between donors and patients.

The relevant laws and regulations regarding the utilization of the deceased as medical research subjects are not yet fully developed in China nowadays. Taking the deceased as research subjects as a starting point, this paper discussed the definition of the deceased and the scope of their interest protection from multiple perspectives. It posited that the scope of interest protection for the deceased encompassed two components: spiritual personality interests and material personality interests represented by the remains. The spiritual personality interests of the deceased included identification information such as name, portrait, reputation, honor, privacy, and personal information, as well as medical and health information. The personal information of the deceased was not directly affected by the individual’s life and death status and remained relatively independent. In terms of ethical review, the research team approached from two perspectives: the remains and the personal information of the deceased. Based on the standard of whether the research subjects involve a human body, research with the remains of the deceased as the medical research subjects was classified as non-clinical research. According to the standard of whether a human body is clinically operated, research with the personal information of the deceased (including medical and health information) as the medical research subjects was recognized as clinical research without human research operation. This approach provided evidence for the application of existing laws and regulations in ethical review and record management. The ethical review of investigator-initiated clinical research conducted in medical and health institutions, as well as the regulatory conditions for exemption from ethical review, were examined. The forms, content, and acquisition of informed consent were summarized, and the risk-benefit characteristics of the research activity were evaluated, with a view to providing a basis for the smooth and compliant implementation of research activities involving the deceased as medical research subjects.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Objective:To investigate the prognostic value of the combined preoperative albumin-globulin score (AGS) and skeletal muscle index (SMI), referred to as the CAS classification, in predicting postoperative outcomes in patients with pancreatic cancer.Methods:The clinical data from 265 patients who underwent surgical treatment and were pathologically confirmed to have pancreatic cancer at the Affiliated Hospital of Qingdao University between January 2012 and December 2022 were retrospectively analyzed. Patients were randomly divided into a training group ( n=184) and a validation group ( n=81) in a 7∶3 ratio. Patients' age, gender, body mass index (BMI), smoking history, alcohol consumption history, previous history of metabolic diseases, AGS, SMI, and CAS classifications within 7 days before surgery, preoperative upper abdominal CT imaging features, presence of vascular and neural invasion, and lymph node metastasis were recorded. Patients with AGS grade 0 were classified into the low AGS group ( n=48), while those with AGS grades 1 and 2 were classified into the high AGS group ( n=136). The optimal cutoff value for SMI was determined using X-tile software: male patients with SMI>42.6 cm 2/m 2 or female patients with SMI>37.8 cm 2/m 2 were categorized into the high SMI group ( n=125), while those below these thresholds were categorized into the low SMI group ( n=59). Patients with AGS grade 0 and SMI>42.6 cm 2/m 2 for males or >37.8 cm 2/m 2 for females were classified into the CAS grade 1 group (n=32). Patients with AGS grades 1 or 2 and SMI ≤42.6 cm 2/m 2 for males or ≤37.8 cm 2/m 2 for females were classified into the CAS grade 3 group ( n=43). The remaining patients were classified into the CAS grade 2 group ( n=109). Clinical characteristics were compared across these groups. Cumulative survival rates were estimated using the Kaplan-Meier method, and survival curves were plotted to analyze the relationship between AGS, SMI, and CAS classifications and overall survival after pancreatic cancer surgery. Differences among groups were assessed using the Log-Rank test. Receiver operating characteristic curves (ROC) were plotted, and the area under the curve (AUC) was calculated to evaluate the predictive efficacy of AGS, SMI, and CAS on postoperative survival. Results:Compared to the high AGS group, the low AGS group exhibited higher SMI values [(46.17±9.63) cm 2/m 2vs (44.11±7.43) cm 2/m 2], and a lower incidence of lymph node metastasis (16 vs 66, 33.3% vs 48.5%). The mortality rate in the low AGS group was 50.0%(24/48), significantly lower than the 70.6% (96/136) observed in the high AGS group, with a median overall survival of 22.08 months (95% CI 16.87-29.62) longer than 13.1 months (95% CI 8.84-18.82) in high AGS group. Compared to the low SMI group, the high SMI group had a lower prevalence of metabolic diseases (26.4% vs 44.1%). The mortality rate in the low SMI group was 78.0% (46/59), higher than the 58.4% (73/125) in the high SMI group, with a median overall survival of 12.97 months (95% CI 9.37-18.20) obviously shorter than 16.20 months (95% CI 10.7-24.12) in high SMI group. Lymph node metastasis rate for CAS grade 1, 2, and 3 was 34.4% ( n=11), 44.0% ( n=48), and 62.8% ( n=27), respectively, with corresponding mortality rate of 34.3% (11/32), 67.9% (74/109), and 79.1% (34/43), and median overall survival time of 25.55 months (95% CI 19.49-30.07), 14.10 months (95% CI 10.22-19.14), and 12.5 months (95% CI 8.53-18.00), respectively. All the differences were statistically significant (all P value <0.05). Kaplan-Meier survival analyses demonstrated that patients in the low AGS group had significantly longer overall survival than those in the high AGS group in both the training and validation cohorts. Similarly, patients in the high SMI group had longer overall survival compared to those in the low SMI group. Notably, patients in CAS grade 1 exhibited the longest overall survival, whereas those in CAS grade 3 had the shortest. ROC curve analysis revealed that the AUC for CAS classification was superior in the training cohort (0.649) compared to AGS (0.588) and SMI (0.593), and in the validation cohort (0.644) compared to AGS (0.587) and SMI (0.577). Conclusions:CAS classification could effectively predict postoperative prognosis in pancreatic cancer patients, with higher CAS grades correlating with poorer outcomes.
