Traditional Chinese medicine(TCM) resources are the essential material foundation for the development of TCM. The national survey of TCM resources serves as a periodic summary of these resources, ensuring the continuity, prosperity, and development of TCM in China. Since 1949, four national surveys of TCM resources have been conducted. The fourth survey incorporated an investigation into traditional knowledge related to TCM resources, including the traditional medicinal knowledge of Chinese ethnic minorities, with the goal of systematically exploring, preserving, and inheriting this knowledge. This manuscript provides an overview of the basic findings from the first three national surveys of TCM resources, while also clarifying the concepts, categories, forms, carriers, and acquisition pathways of traditional knowledge related to TCM resources. A preliminary summary of the findings from traditional knowledge investigations reported in current literature is also presented. Based on the fourth survey, this manuscript emphasizes the urgency of developing public medical knowledge through empirically-based investigations, the excavation, and compilation of traditional knowledge. It also outlines the potential for conducting "precise" investigations based on first-hand data obtained from the survey, as well as facilitating the discovery and evaluation of new medicines using traditional knowledge related to ethnic minority medicinal practices. This manuscript is expected to provide valuable insights for promoting the health and industrial development of ethnic minority populations in the post-"survey" phase.

Dendritic cells (DCs) serve as the primary antigen-presenting cells in autoimmune diseases, like rheumatoid arthritis (RA), and exhibit distinct signaling profiles due to antigenic diversity. Type II collagen (CII) has been recognized as an RA-specific antigen; however, little is known about CII-stimulated DCs, limiting the development of RA-specific therapeutic interventions. In this study, we show that CII-stimulated DCs display a preferential gene expression profile associated with migration, offering a new perspective for targeting DC migration in RA treatment. Then, saikosaponin D (SSD) was identified as a compound capable of blocking CII-induced DC migration and effectively ameliorating arthritis. Optineurin (OPTN) is further revealed as a potential SSD target, with Optn deletion impairing CII-pulsed DC migration without affecting maturation. Function analyses uncover that OPTN prevents the proteasomal transport and ubiquitin-dependent degradation of C-C chemokine receptor 7 (CCR7), a pivotal chemokine receptor in DC migration. Optn-deficient DCs exhibit reduced CCR7 expression, leading to slower migration in CII-surrounded environment, thus alleviating arthritis progression. Our findings underscore the significance of antigen-specific DC activation in RA and suggest OPTN is a crucial regulator of CII-specific DC migration. OPTN emerges as a promising drug target for RA, potentially offering significant value for the therapeutic management of RA.

Objective To study the prevalence trends and etiology of hand,foot,and mouth disease (HFMD) in hospitalized children.Methods The clinical data of 11 510 cases of children hospitalized with HFMD from 2008 to 2017 in Department of Infection Diseases of Kunming Children's Hospital were collected,and to retrospectively analyze the characteristics,time distribution and pathogen distribution of the cases.Results Of the 11 510 children with HFMD,6 100 were male and 5 410 were female.There were 9 814 cases under 3 years old,1 696 over 3 years old.HFMD occurred throughout the year.The peak months of the disease were April to July,with the time distribution of single peak.There were 4 690 severe cases and 3 452 critical cases,accounting for 70.34％.The main pathogens detected were enteroviruses A71 (EV-A71),coxsackievirus A16 (CV-A16) and other enteroviruses (EV),with 3 803 cases (36.02％),1 122 cases (10.63％) and 3 401 cases (32.21％) respectively.EV-A71 and CV-A16 infections dominated from 2008 to 2013,while EV-A71 and other EV infection dominated from 2014 to 2017.Conclusions EV-A71,CV-A16 and other EV are the main pathogens of HFMD in Kunming.Critical HFMD cases are mainly caused by EV-A71 infection.
