On the basis of reviewing the academic history of authentication of ancient traditional Chinese medicine （TCM） classics， this paper systematically expounds the theoretical foundations of bibliography in authentication. It discusses six specific approaches and their practical applications， including examining the bibliographic records in successive dynastic catalogues to verify the chronological sequence of transmission， comparing differences in bibliographic classification to discern authenticity， investigating author information to identify pseudepigraphic forgeries， comprehensively applying various bibliographies to identify the titles and editions of volumes and chapters， examining block-print dating information to detect fraudulent publication imprints， and verifying traces of collection and circulation to identify forged seals， colophons， and inscriptions. Finally， the paper explores the contemporary value and future directions of bibliographic authentication， which are of significant theoretical and practical importance for promoting the modern transformation of bibliographic authentication methodology and for advancing research on the authentication of ancient TCM texts.

The 20th National Congress of the Communist Party of China emphasized the expansion of international scientific and technological exchanges and cooperation. Against this backdrop, the radiological health research institutions bear important responsibilities in the field of international radiological health. As a key institution in the industry, the National Institute for Radiological Protection (NIRP), Chinese Center for Disease Control and Prevention shoulders the important mission of promoting international exchanges in radiation health in China. A case study was conducted on the NIRP using data of official overseas visits from 2010 to 2024. The SWOT analysis was used to comprehensively and systematically examine the strengths, weaknesses, opportunities, and challenges of NIRP in international cooperation and exchanges. To effectively enhance the depth and scope of international exchanges, this article proposes a series of innovative optimization strategies such as establishing dedicated personnel positions to ensure efficient handling of affairs, implementing stringent approval procedures to guarantee the rationality and compliance of overseas visits, strengthening pre-departure training to improve the professionalism of outbound personnel, conducting follow-up evaluations to continuously refine management practices, and centralizing the management of official passports to ensure their secure use. This article aims to provide practical optimization strategies for the management of official overseas visits for NIRP and other similar institutions, promote international exchanges and cooperation in the field of radiation health, and help China play a more important role in the global radiation health field.

Objective The aim of this study was to investigate the microbiological characteristics and antimicrobial resistance of Nocardia isolates in Hebei Province during the 9-year period.Methods The medical records of all hospitalized patients from whom Nocardia was isolated from 2015 to 2023 were analyzed retrospectively.The isolates were identified to the species level by amplification and sequencing of 16S rRNA,secA1 and ropB genes of Nocardia.Antimicrobial susceptibility of Nocardia isolates were tested by microbroth dilution method.Results Of the 162 strains of Nocardia,128(79.0％)were isolated from respiratory tract specimens,followed by skin and soft tissue infection(25/162,15.4％).Most of the patients with respiratory tract infection were elderly(＞65 years old).Most of the patients with skin and soft tissue infection were middle-aged and elderly(＞45 years old).Twelve species were identified among the 162 isolates.The most common species were N.cyriacigeorgica(36.4％,59/162),N.farcinica(25.3％,41/162),and N.otitidiscaviarum(9.9％,16/162).The most common Nocardia species isolated from the respiratory tract was N.cyriacigeorgica,followed by N.farcinica.The most common species causing skin and soft tissue infection were N.cyriacigeorgica,N.farcinica and N.brasiliensis.All Nocardia strains were susceptible to linezolid,followed by 98.8％susceptible to amikacin and 98.1％susceptible to trimethoprim-sulfamethoxazole(TMP-SMZ).Conclusions Nocardia is mainly isolated from respiratory tract,skin and soft tissues.N.cyriacigeorgica and N.farcinica are the most prevalent species.TMP-SMZ is the first choice for treatment of nocardiosis.Combination therapy may be appropriate for moderate and severe infections according to the results of antimicrobial susceptibility testing.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.
