OBJECTIVE To provide suggestions for improving the path and system construction of patient engagement in drug regulation in China. METHODS By reviewing initiatives and experiences from the United States (U. S.), European Union (EU), and Japan in promoting patient engagement, this study summarizes the roles and contributions of patients in the entire drug regulatory process internationally. Combining China’s current progress and challenges in patient engagement, specific proposals are formulated to refine regulatory pathways and institutional systems. RESULTS & CONCLUSIONS With growing global emphasis on patient engagement as a regulatory strategy, countries or regions such as the U.S., EU, and Japan have established clear policies, designated oversight agencies, and developed diversified pathways for patient engagement. Patients contribute to regulatory processes through advisory meetings, direct decision-making roles, and leveraging lived experiences and expertise to optimize drug evaluation and monitoring. In contrast, China’s patient engagement remains primarily limited to clinical value- oriented drug development, lacking formal policy guidance. It is recommended that China, based on its existing policy system, further strengthen the construction of a safeguard system for patient engagement, improve the capacity building and pathway models for patient participation in pharmaceutical regulation, and promote the continuous development of patient engagement in pharmaceutical regulation in our country.

Laboratory animals serve as the cornerstone in life science research, acting as surrogate models for human physiology, pathology, and disease treatment. They play an irreplaceable role in basic research, drug development, and translational medicine. Gut microbiota, a complex microbial community comprising bacteria, fungi, viruses, and unicellular organisms, colonizes the host's intestinal tract and is closely associated with the maintenance of normal physiological metabolism and overall health. Studies have shown that dysbiosis of the gut microbiota can lead to various diseases, including obesity, diabetes, hypertension, inflammatory bowel disease, and Alzheimer's disease. Therefore, conducting characteristic analyses of the gut microbial composition of laboratory animals can not only enhance the reliability of experimental outcomes but also facilitate their translational application. Sex differences represent a critical variable in biological research, significantly influencing the physiological functions, metabolic traits, and gut microbial composition of laboratory animals. However, a pronounced sex bias has been widely observed in many biological studies, thereby limiting the generalizability of results. This study focused on ten commonly used laboratory animals in life sciences, including mice, rats, guinea pigs, hamsters, rabbits, dogs, cats, non-human primates, miniature pigs, and chickens. Their gut microbial composition was summarized and related sex-specific differences of certain species were analyzed. Furthermore, by comparing the gut microbiota of laboratory animals with that of humans, this study offers novel perspectives for comparative medical research. In summary, this study not only deepens researchers' understanding of gut microbiota characteristics and sex-dependent variations across laboratory animal species but also provides practical guidance for selecting appropriate laboratory animals, constructing sex-specific disease models, and interpreting experimental results in scientific studies.

OBJECTIVE To analyze the current status and challenges in importing rare disease drugs in China, providing references for optimizing the import process and improving relevant policies. METHODS Questionnaires and interviews were conducted with stakeholders involved in rare disease drug importation, including government departments, multinational pharmaceutical enterprises, healthcare institutions, and patient organizations. This explored the current situation and challenges encountered by each party. Expert opinions were synthesized to propose improvement suggestions. RESULTS A questionnaire survey of representatives from 25 multinational pharmaceutical companies in the rare disease field revealed that these companies had a strong willingness to import rare disease drugs, with 58.33% of them practicing diverse import models. However, significant challenges hindered this process, including unclear regulations (54.17%), complex approval procedures (45.83%), and excessively long approval cycles (41.67%), negatively impacting their motivation. Meanwhile, interviews with 13 experts from government departments, healthcare institutions, pharmaceutical enterprises, and patient organizations identified deficiencies in policy design, approval processes, sampling inspection costs, and communication efficiency with regulators. Additionally, the drug import model in special medical zones also required improvement. CONCLUSIONS The importation of rare disease drugs in China faces challenges such as incomplete policies, inflexible regulatory mechanisms, and insufficient communication channels. It is recommended to enhance the rare disease definition criteria, optimize import incentive policies, and refine regulatory models, so as to further optimize the import process of rare disease drugs and improve relevant policies.

ObjectiveTo investigate the alleviating effect of calcium cyanamide (CaCN2) soil fumigation on replanting problems of Rehmannia glutinosa. MethodsNewly soil (NP) was used as the control group, while three treatment groups were established: replanted soil (RP), newly soil treated with CaCN2 (120 g·m², tillage depth 25 cm) (NPCC), and replanted soil treated with CaCN2 (RPCC). R. glutinosa was cultivated in all groups. At harvest, the tuber agronomic traits (number of enlarged roots, maximum root diameter, fresh weight, dry weight) were measured. The content of catalpol and rehmannioside D was quantified by ultra-high-performance liquid chromatography (UPLC) to evaluate medicinal quality. Rhizosphere soil available nutrients and enzyme activities were analyzed by assay kits. The community structure and composition of fungi and bacteria in rhizosphere soil were assessed via internal transcribed spacer 2 (ITS2) sequencing and 16S rDNA sequencing, respectively. ResultsCompared with NP, the RP group showed obviously reduced in tuber agronomic traits and quality indicators (P0.05). However, the RPCC group showed significant improvement in agronomic traits and a notable increase in rehmannioside D content compared to RP (P0.05). The contents of available phosphorus and potassium in RPCC and NP groups were obviously lower than those in RP (P0.05). The polyphenol oxidase soil (S-PPO) activity in RP was obviously lower than in NP (P0.05), while sucrose soil (S-SC), acid phosphatase soil (S-ACP), and S-PPO activities in RPCC were obviously higher than in RP (P0.05). Microbial richness and diversity in RP were obviously higher than in NP (P0.05), whereas no significant differences were observed between the RPCC and NP. The relative abundances of fungal genera Nectria, Myrothecium, Tomentella, and bacterial genus Skermanella were obviousl lower in RPCC and NP than in RP (P0.05). Correlation analysis that S-ACP activity was positively correlated with the content of rehmannioside D (P0.05). Fungal genera Engyodontium and Alternaria, and bacterial genera Pir4 lineage, Pirellula, Methyloversatilis, Brevundimonas, Ralstonia, and Acidibacter were obviously positively correlated with tuber dry weight (P0.05). Conversely, fungal genera Pseudaleuria, Nectria, Haematonectria, Ceratobasidium, and bacterial genera Streptomyces, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated with dry weight (P0.05). The fungal genus Alternaria and bacterial genera Brevundimonas, Ralstonia, Acidibacter, and Dongia showed positive correlations with medicinal quality of R.glutinosa tuber, while fungal genera Pseudaleuria, Nectria, Stachybotrys, Fusarium, Gibberella, Ceratobasidium, and bacterial genera Sphingomonas, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated (P0.05). ConclusionCaCN2 soil fumigation can significantly improve enzyme activities in replanted Rehmannia rhizosphere soil, enhance the utilization of available nutrients, reshape microbial community structure of replanted R.glutinosa at the family and genus level, and notably improve tuber agronomic traits and medicinal quality. This study provides a novel approach to alleviating replanting problems and offers insights for the integrated development of standardized cultivation techniques, including soil disinfection, nutrient-targeted regulation, and microbial inoculant application.
