On the occasion of celebrating the 110th anniversary of the Chinese Medical Association, the authors take the Chinese Journal of Digestive Surgery, a leading Chinese journal under the excellent action plan for Chinese scientific and technological journals, as the research subject to systematically analyze practices in academic exchange and scientific innovation develop-ment models advocated by the Chinese Medical Association. Through establishing a pyramid-shaped academic ecosystem, implementing strategic guidance with standard outputs, and building collabo-rative empowerment mechanisms, the journal has achieved breakthrough improvements in academic influence and communication efficacy. The study reveals that Chinese scientific journals can effec-tively overcome traditional development constraints by deeply integrating with national strategies, reconstructing academic value chains, and innovating knowledge service models, thereby providing China-specific solutions for constructing world-class scientific journals.

With the acceleration of aging society in China, acute obstructive suppurative cholangitis (AOSC) in the extremely elderly (≥80 years) patients has become a common and frequent acute abdominal disease, which seriously threatens national strategy of "healthy aging" in China. Endoscopic retrograde cholangiopancreatography (ERCP) is currently the mainstream treatment for AOSC, but emergency ERCP treatment for elderly patients with AOSC is limited. In recent years, laparoscopic surgery targeting laparoscopic transcystic common bile duct exploration (LTCBDE) has been an ideal treatment method, but it has a high surgical risk. The authors′ team has conducted in-depth exploration into the advantages and disadvantages of ERCP treatment, strategies for repairing Oddi sphincter function, selection of laparoscopic surgical methods, and formulation of safety guarantee measures, and has carried out the technical improvements on LTCBDE, aiming to enhance the feasibility and safety of this surgical method in the treatment of AOSC in extremely elderly patients.

On the occasion of the 110th Anniversary of the establishment of the Chinese Medical Association, the third conference of the Fourth Editorial Board of Chinese Journal of Digestive Surgery, and the Second Elite Group of Chinese Journal of Digestive Surgery, was successfully held in Kunming on July 4, 2025. This conference systematically summarizes the development experience of the journal over the past 20 years from three aspects: the role of ecological construction of thought in the discipline construction of digestive surgery, the display of the latest academic achievements in the field of digestive surgery, the development difficulties, and breakthrough paths of the discipline, and strategically plans the path of discipline construction in the new era.

Objective:To investigate the computed tomography (CT)-based integrated deep learning model for qualitative and quantitative classification of hepatic portal vein.Methods:The retrospective study was conducted. The CT imaging data of 291 patients undergoing upper-abdomen enhanced CT examination in the Beijing Tsinghua Changgung Hospital of Tsinghua University from October 2017 to January 2019 were collected. There were 195 males and 96 females, aged (51±12)years. The hepatic portal vein was reconstructed using the three-dimensional reconstruction system. Three-dimensional point cloud was input to the encoder model to obtain the three-dimen-sional reconstructed vectorized representation, which was used for qualitative classification and quantitative representation classification. Measurement data with normal distribution were repre-sented as Mean± SD, and comparison between groups was conducted using the paired t test. Count data were repre-sented as percentages or absolute numbers, and comparison between groups was analyzed using the paired chi-square test. Results:(1) Three-dimensional reconstruction of portal vein and anatomical classification. Three-dimensional structure was reconstructed in the 291 patients. Classification of main hepatic portal vein showed 211 cases of Akgul type A, 29 cases of Akgul type B, 16 cases of Akgul type C, 10 cases of Akgul type D, and 25 cases of unclassifiable. (2) Prediction of qualitative classification of main hepatic portal vein. Of the 291 patient samples, 25 unclassifiable or poor quality samples were excluded, 266 samples were used for automated qualitative classification of the main portal vein by machine model. There were 211 cases of Akgul type A, 29 cases of Akgul type B, 26 cases of Akgul type C&D. The Macro-F1 of 266 patients was 61.93%±40.50% and the accuracy was 84.99%, versus 32.38%±19.81% and 61.65% of Random classifier, showing significant differ-ences between them ( t=7.85, χ2=62.89, P<0.05). (3) Quantitative representation of portal vein classification. The probabilities of quantitative classification for Akgul qualitative classification of similar samples included P@1 as 73%±45%, P@3 as 70%±37%, P@5 as 69%±35%, P@10 as 67%± 32%, mean reciprocal rank(MRR) as 80%±34%, versus 57%±50%, 58%±35%, 58%±32%, 58%± 30%, 70%±37% of the baseline model, showing significant differences between the two analytical methods ( t=5.22, 5.11, 5.00, 4.99, 3.47, P<0.05). Conclusion:The automated classification model for the hepatic portal vein structure was constructed using CT-based three-dimensional reconstruc-tion and deep learning technology, which can achieve automatic qualitative classification and quanti-tatively describe the hepatic portal vein structure.
