BACKGROUND

Internationalization in medical education aims to align programs with global standards, foster intercultural competence, and expand academic collaboration. In private medical schools in Northern Luzon, clarifying how internationalization is conceptualized and enacted can enhance the medical curriculum.

To explore how private medical schools in Northern Luzon conceptualize and implement internationalization, identify associated challenges, and propose curriculum inputs to enhance delivery of the medical curriculum.

The qualitative study utilized a multiple case study design. The study was approved by the Saint Louis University Research Ethics Committee. Using purposive sampling, 45 participants from private institutions in Northern Luzon Philippines consented to engage in focus group discussions and in-depth interviews from February to April 2025. Data were analyzed through inductive content and thematic techniques.

Participants conceptualized internationalization as (1) alignment with international quality and practice standards; (2) global engagement and exchange encompassing knowledge, skills, culture, institutional networking, and collaboration; (3) inclusivity and multicultural responsiveness; and (4) pursuit of global recognition and accreditation. Implementation occurred via “internationalization at home” (embedding global perspectives in local learning environments), “internationalization abroad” (student/faculty mobility and external exposure), and alignment of philosophical and curricular frameworks. Reported challenges included institutional and curricular constraints, language and cultural barriers, sociocultural and financial limitations, and external/contextual pressures.

Addressing the identified barriers and scaling the documented practices can enhance the delivery of the medical curriculum. The study offers actionable curricular revisions that private institutions may adopt to strengthen internationalization in medical education.

The growing use of generative artificial intelligence (AI) has coincided with more timely manuscript submissions and improved efficiency in scientific writing. While AI tools help authors produce clear and well-structured work, excessive or undisclosed reliance raises concerns about originality, authenticity, and the integrity of scholarly publications. Editors increasingly recognize AI-assisted writing and face the challenge of preserving rigorous standards. Emerging guidelines emphasize transparency in AI use, alongside the need to retain individual voice and diversity in scientific expression. This editorial highlights the balance between leveraging AI’s benefits and safeguarding ethical publication practices, while acknowledging contributors to the current issue.

Tujia ethnic group medicine Xuetong is derived from Kadsura heteroclita, the stem of which has the medicinal value for anti-rheumatoid arthritis, liver protection, anti-tumor, anti-oxidation effects, and has been widely used in Hunan and Guangdong in China. The selection of reliable and stable reference genes is the basis for subsequent molecular research on K. heteroclita. In this study, GAPDH, TUA, Actin, UBQ, EF-1α, 18S-rRNA, CYP, UBC, TUB, H2A, and RPL were selected as candidate reference genes in Kadsura heteroclita. The gene expression levels of the 11 candidate reference genes of K. heteroclita in its 6 different parts(stem-inside of the cambium, stem-outside of the cambium, fruit, flower, root, and leaf) and under different intervention conditions [drought stress, salt stress, and methyl jasmonate(MeJA) treatment] were detected by quantitative real-time polymerase chain reaction(qRT-PCR). The expression stability of the 11 candidate reference genes was comprehensively analyzed and evaluated by geNorm, NormFinder, ΔCT algorithm, and RefFinder software. The results showed that the expression of UBC and RPL was relatively stable in 6 different parts, and UBC and GAPDH genes were relatively stable under different intervention conditions. To verify the reliability of reference genes for K. heteroclita, this study further examined the relative expression levels of KhFPS, KhIDI, KhCAS, KhSQE, KhSQS, KhSQS-2, KhHMGS, KhHMGR, KhMVD, KhMVK, KhDXR, KhDXS, KhPMVK, and KhGGPS in different parts and under different intervention conditions, which might relate to the synthesis of the main component(Xuetongsu) of K. heteroclita. The results showed that with UBC and RPL or UBC and GAPDH as the reference genes, the expression trends of these 14 genes were basically consistent in different parts or under different intervention conditions for K. heteroclita. In conclusion, UBC can be used as a reference gene of K. heteroclita for its different parts and different intervention conditions, which lays a foundation for further research on the biosynthetic pathway of main components in K. heteroclita.

The formulation and revision of the detection methods of indoor air quality standards is an important, rigorous and delicate endeavor. The standards for indoor air quality (GB/T 18883-2022) were issued by the State Administration of Market Regulation and the Standardization Administration on July 11, 2022, and implemented on February 1, 2023 by replacing indoor air quality standards (GB/T 18883-2002). The revised standard specifies hygienic requirements for physical, chemical, biological and radioactive indicators in indoor air and the corresponding test methods. This article interpreted the revision background, drafting principles, main indicators and methods, as well as the revision basis of the standards. Recommendations for the implementation of the standards are also proposed.

Body mass index (BMI) is widely recognized as an important indicator of physical health. However, the current BMI standard and guidelines primarily focus on children and general adults, neglecting the specific needs of the oldest old aged 80 years or older. To address this gap, this guideline aims to provide recommendations on the appropriate range of BMI and weight management for the oldest old in China, including age calculation, defining the appropriate BMI range, BMI measurement indicators, and weight management strategies. It is intended to be utilized by medical and health organizations at all levels, as well as medical and nursing service institutions, to evaluate the BMI and manage the weight of the oldest old population.
