The global distribution of medical resources is uneven and organ shortages are becoming increasingly serious. ASEAN countries have been working hard to explore and promote local organ transplantation in order to alleviate the serious imbalance between organ donation and organ transplantation needs. However, the development of cadaveric organ donation varies among ASEAN countries, and the cadaveric organ donation rate in most countries is generally low. Since 1991, China and ASEAN have evolved from dialogue to strategic cooperation, then to a community with a shared future, and further to a comprehensive strategic partnership, all demonstrating broad prospects for cooperation. This article analyzes the current situation and challenges of organ donation and transplantation in ASEAN countries, combining field visits and its own experience, and proposes strategies for strengthening international cooperation, optimizing policy environment, enhancing technical capabilities, and increasing public awareness in the field of organ donation and transplantation under the China-ASEAN development strategy framework. The aim is to build a more equitable, efficient, and sustainable organ donation and transplantation system, contributing to the realization of global public health security and a community of common health for mankind.

Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

Objective:To assess the risk factors affecting development of non-tumor- related anastomotic stenosis after rectal cancer and to construct a nomogram prediction model.Methods:This was a retrospective study of data of patients who had undergone excision with one-stage intestinal anastomosis for rectal cancer between January 2003 and September 2018 in Nanfang Hospital of Southern Medical University. The exclusion criteria were as follows: (1) pathological examination of the operative specimen revealed residual tumor on the incision margin of the anastomosis; (2) pathological examination of postoperative colonoscopy specimens revealed tumor recurrence at the anastomotic stenosis, or postoperative imaging evaluation and tumor marker monitoring indicated tumor recurrence; (3) follow-up time <3 months; and (4) simultaneous multiple primary cancers. Univariate analysis using the χ 2 or Fisher's exact test was performed to assess the study patients' baseline characteristics and variables such as tumor-related factors and surgical approach ( P<0.05). Multivariate analysis using binary logistic regression was then performed to identify independent risk factors for development of non-tumor-related anastomotic stenosis after rectal cancer. Finally, a nomogram model for predicting non-tumor-related anastomotic stenosis after rectal cancer surgery was constructed using R software. The reliability and accuracy of this prediction model was evaluated using internal validation and calculation of the area under the curve of the model's receiver characteristic curve (ROC). Results:The study cohort comprised 1,610 patients, including 1,008 men and 602 women of median age 59 (50, 67) years and median body mass index 22.4 (20.2, 24.5) kg/m2. Non-tumor-related anastomotic stenosis developed in 121 (7.5%) of these patients. The incidence of non-tumor-related anastomotic stenosis in patients who had undergone neoadjuvant chemotherapy, neoadjuvant radiotherapy, and surgery alone was 11.2% (10/89), 26.4% (47/178), and 4.8% (64/1,343), respectively. Neoadjuvant treatment (neoadjuvant chemotherapy: OR=2.455, 95%CI: 1.148–5.253, P=0.021; neoadjuvant chemoradiotherapy, OR=3.882, 95%CI: 2.425–6.216, P<0.001), anastomotic leakage (OR=7.960, 95%CI: 4.550–13.926, P<0.001), open laparotomy (OR=3.412, 95%CI: 1.772–6.571, P<0.001), and tumor location (distance of tumor from the anal verge 5–10 cm: OR=2.381, 95%CI:1.227–4.691, P<0.001; distance of tumor from the anal verge <5 cm: OR=5.985,95% CI: 3.039–11.787, P<0.001) were identified as independent risk factors for non-tumor-related anastomotic stenosis. Thereafter, a nomogram prediction model incorporating the four identified risk factors for development of anastomotic stenosis after rectal cancer was developed. The area under the curve of the model ROC was 0.815 (0.773–0.857, P<0.001), and the C-index of the predictive model was 0.815, indicating that the model's calibration curve fitted well with the ideal curve. Conclusion:Non-tumor-related anastomotic stenosis after rectal cancer surgery is significantly associated with neoadjuvant treatment, anastomotic leakage, surgical procedure, and tumor location. A nomogram based on these four factors demonstrated good discrimination and calibration, and would therefore be useful for screening individuals at risk of anastomotic stenosis after rectal cancer surgery.

Objective : To study the effect of deep learning applied to the assisted diagnosis of radiolucent lesions and radiopaque lesions of the jaws in panoramic radiography and to reduce the missed diagnosis, with early screening to assist doctors to improve the diagnostic accuracy. Methods: This study was approved by the Ethics Committee of the West China Stomatological Hospital of Sichuan University. The YOLO v8m-p2 neural network model was constructed with 443 panoramic images as a subject to read. The labeled images were divided into 354 training sets, 45 verification sets, and 44 test sets, which were used for model training, verification, and testing. Accuracy, recall, F-1 score, G score, and mAP50 were used to evaluate the detection performance of the model. Results: 443 panoramic images covered the common benign lesions of the jaw, the number of radiolucent lesions of the jaw was 318, containing dentigerous cyst, odontogenic keratocyst, and ameloblastoma. The number of radiopaque lesions was 145, containing idiopathic osteosclerosis, odontoma, cementoma, and cemento-osseous dysplasia; the samples are well representative. The accuracy of the YOLO v8m-p2 neural network model in identifying jaw lesions was 0.887, and the recall, F-1 score, G score, and mAP50 were 0.860, 0.873, 0.873, and 0.863, respectively. The recall rates of dentigerous cyst, odontogenic keratocyst, and ameloblastoma were 0.833, 0.941, and 0.875, respectively. Conclusion YOLO v8m-p2 neural network model has good diagnostic performance in preliminary detection of radiolucent and radiopaque lesions of the jaws in panoramic radiography and multi-classification monitoring of radiolucent lesions of jaws, which can assist doctors to screen jaw diseases in panoramic radiography.

The innovation of integrating medical treatment and prevention mechanisms is a key task deployed by the government, aiming to promote the construction of a Healthy China and address the prevalent "treatment over prevention" mindset in healthcare services and society. Vaccination is an effective strategy for preventing and controlling infectious diseases; however, adult vaccination rates in China remain low due to insufficient awareness and enthusiasm among the public and healthcare professionals. In recent years, various regions have begun to explore the model of physicians in medical institutions prescribing vaccines to improve vaccination rates. This article analyzes the positioning, current implementation status, and challenges of vaccine prescriptions, and proposes recommendations advocating policy formulation, improving service models and supporting measures, improving funding mechanisms, and strengthening publicity and education to promote the widespread implementation and effectiveness of vaccine prescriptions.

Objective To summarize and analyze the clinical first aid characteristics and etiology classi-fication of adult acute laryngeal obstruction so as to guide the targeted treatment in clinic.Methods The clini-cal data of the patients with the main symptoms such as suffocation and inspiratory dyspnea visiting in this hospital from January 2015 to December 2021 were collected.They conducted emergency tracheotomy for first aid,and their etiological distribution and characteristics were analyzed.Results A total of 94 patients with a-cute laryngeal obstruction and emergency tracheotomy caused by various causes were collected,73 males and 21 females,aged (65.44±12.23)years old.The proportions of disease causes from high to low were in turn 60 cases of tumor (63.83％),12 cases of bilateral vocal cord paralysis (12.77％),11 cases of inflammation (11.70％),5 cases of trauma (5.32％),2 cases of laryngeal edema (2.13％),2 cases of giant foreign matter (2.13％) and 2 cases of tube taking off after tracheotomy (2.13％).The age had the statistical difference a-mong different etiologies (F=4.463,P=0.001).The age in the patients with tumor,infection and bilateral vocal cord paralysis was greater than that of the other groups with statistical difference[(67.21±10.45)years old vs.(52.00±16.42)years old,t=2.993,P=0.012].The male patients with different severities of acute la-ryngeal obstruction were more than female patients,but the difference in the sex composition was not statisti-cally significant (P=0.469).Among the patients with emergency tracheotomy,there were 6 cases of compli-cating incision bleeding and 5 cases of subcutaneous emphysema;1 case of right pneumothorax complicating apposite side atelectasis,and all were improved by symptomatic treatment.Conclusion Acute laryngeal ob-struction in adults is critical.The common causes include tumor,bilateral vocal cord paralysis and inflamma-tion.The risk of emergency tracheotomy and complications occurrence risk are relatively high.

"Chinese model" of organ donation and transplantation in China has won acclaims from all over the world. Current contradictions between unbalanced and inadequate development of organ donation and transplantation and surging public demands for transplant services remain serious. And an acute shortage of donated organs is still the greatest difficulty. Improving organ donation rate per million population (PMP) and organ utilization rate has been a great challenge for organ donation teams in China. This review summarized the relevant experiences of Second Affiliated Hospital of Guangxi Medical University in fostering organ donation culture atmosphere and connotation to accelerate the high-quality development of organ donation. It was intended to provide references for disciplined construction of other organ donation management teams and promote the development of organ donation and transplantation in China.
