As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

ObjectiveBased on traditional quality evaluation of Gardeniae Fructus（GF） recorded in historical materia medica， this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics， microscopic features， and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length， diameter and individual fruit weight of wild and cultivated GF， and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF， and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently， the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China， the starch content was measured by anthrone colorimetric method， the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method， the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection（HPLC-ELSD）， and the contents of representative components in them were measured by ultra-performance liquid chromatography（UPLC）. Finally， correlation analysis was conducted between quality traits and phenotypic traits， combined with multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， key differential components between wild and cultivated GF were screened. ResultsIn terms of traits， the wild GF fruits were smaller， exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger， displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF， while the blue-yellow value（b^*） of wild GF was significantly higher than that of cultivated GF. In the microstructure， the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals， while the endocarp contained stone cell class round， polygonal or tangential prolongation， undeveloped seeds were visible within the fruit. In contrast， the mesocarp of cultivated GF contained few calcium oxalate cluster crystals， or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like， with the innermost layer arranged in a grid pattern. Seeds were basically mature， and only a few immature seeds existed in some batches. Regarding primary metabolite content， wild GF exhibited significantly higher total polysaccharide level than cultivated GF（P<0.01）. In category-specific component content， wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF（P<0.01）. Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside， deacetyl asperulosidic acid methyl ester， gardenoside and chlorogenic acid compared to cultivated GF（P<0.01）. Conversely， the contents of genipin 1-gentiobioside， geniposide and genipin were significantly lower in wild GF（P<0.01）. ConclusionThere are significant differences between wild and cultivated GF in terms of traits， microstructure， and contents of primary and secondary metabolites. At present， the quality evaluation system of cultivated GF remains incomplete， and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Objective:To investigatethe effects of different blood lead levels on indicators of immune function in occupationally lead-exposed populations.Methods:From October to December 2023, a total of 126 occupationally exposed lead workers of a company in Guizhou Province were selected, and their basic information was collected through questionnaires. Inductively coupled plasma mass spectrometry was used to detect blood lead levels in the study population. Workers were categorized into Group 1, Group 2 and Group 3 based on blood lead levels (blood lead levels <200 μg/L, 200~400 μg/L and >400 μg/L). Lymphocyte subpopulation marker leukocyte differentiation antigen (CD) in peripheral blood and interleukin (IL) -1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17, tumor necrosis factor-alpha (TNF-α), and interferon (IFN) -γ in serum were examined by flow cytometry. Serum levels of immunoglobulin (Ig) A, IgG, IgM, and complement proteins (C3, C4) were measured by immunoscattering turbidimetry. Data were statistically analyzed using rank sum test, Chi-square test or Fisher exact probability method for multiple samples.Results:Compared with group 1, the percentage of CD3 +CD8 + and CD4 +CD25 + cells decreased ( P<0.05) and the percentage of CD4 + CD95 + cells increased in the lead-exposed populations in groups 2 and 3 ( P<0.05) ; however, the serum IL-1β, IL-2, IL- 5, IL-8, IL-12p70, and IFN-γ levels were decreased ( P<0.05) in group 3. Meanwhile, IgG ( P<0.05) and IgM levels in serum of lead-exposed population in group 2 and group 3 were reduced ( P<0.05) comparing with group 1. Spearman correlation analysis showed that blood lead levels of workers were negatively correlated with the percentage of peripheral blood CD8 +CD95 + cells, CD3 +CD8 + cells, CD3 -CD16 + CD56 + cells, IgG, IgM, and IgA ( rs=-0.20, -0.22, -0.23, -0.24, -0.26, -0.35, P<0.05), but was positively correlated with the level of CD3 +CD4 + cells ( rs= 0.18, P<0.05). Regression analysis revealed that blood lead level was a risk factor for the percentage of CD8 +CD95 + cells, CD3 +CD8 + cells, CD3 -CD16 + CD56 + cells, IgG, IgM, and IgA ( P<0.05) . Conclusion:Different lead loads can lead to abnormal changes in peripheral blood lymphocyte subsets, cytokines, and immunoglobulin levels in occupationally lead-exposed people. Lead exposure in occupationally lead-exposed populations may affect their immune function.

Objective:To explore the design requirements of nurses in the Neurointensive Care Unit (NICU) for the closed-eye pupil monitoring system, providing reference for the refinement and upgrade of the system.Methods:This study was descriptive and qualitative. From December 2024 to February 2025, 15 NICU nurses from Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, were selected using purposive sampling for semi-structured interviews. Content analysis method was used to analyze data and extract key themes.Results:NICU nurses' design requirements for closed-eye pupil monitoring system were categorized into six themes and 18 sub-themes, namely physical characteristics requirements (strong device stability, compact and lightweight design), comfort and safety requirements (wear comfort and safety, prevention of light source thermal injury, convenient disinfection and infection control, assisting eyelid closure), functional requirements (automated monitoring and data collection, intelligent alarm and alert mechanisms), operational requirements (ready-to-use, easy to wear, simple operation), data monitoring requirements (data storage and integrity, data visualization and timeliness, data analysis and prediction, system integration and data management), and extended functional requirements (consciousness state monitoring, fundus lesion examination, vision and visual field screening) .Conclusions:NICU nurses' design requirements for the closed-eye pupil monitoring system are multidimensional and multi-level. System developers should continuously optimize system design based on the actual needs of nurses.

Conclusions:Among elderly DR-PTB patients, the proportions of female, unemployed individuals and other occupations, initial treatment cases, smear-negative but culture-positive cases, polyresistant PTB, and extensively drug-resistant PTB are increasing annually.Future efforts should focus on targeted prevention and treatment for key populations to further reduce the rate of elderly DR-PTB.

With the completion of the "Human Genome Project" and the smooth progress of the "Herbal Genome Project", the research wave of RNAomics is gradually advancing, opening the research gateway for the modernization of traditional Chinese medicine (TCM) and initiating the post-genome era of medicinal plant RNA research. Therefore, this article proposes for the first time the concept of HerbRNomes, which involves constructing databases of medicinal plant, medicinal fungus, and medicinal animal RNA at different stages, from different origins, and in different organs. This research aims to explore the role of HerbRNA in self-genetic information transmission, functional regulation, as well as cross-species regulation functional mechanisms and key technologies. It also investigates application scenarios, providing a theoretical basis and research ideas for the resistance of TCM or medicinal plants to adversity and stress, molecular assistant breeding, and the development of small nucleic acid drugs. This article reviews recent research progress in elucidating the molecular mechanisms of the transmission and expression of genetic information, self-regulation and cross-species regulation of herbs at the RNA level, along with key technologies. It proposes a development strategy for small nucleic acid drugs based on HerbRNomes, providing theoretical support and guidance for the modernization of TCM based on HerbRNomes research.

Purpose: Plasmablastic lymphoma (PBL) is a rare, aggressive lymphoma that is characterized by terminal B-cell differ‑ entiation. In the West, PBL usually occurs in patients with immunodeficiencies, particularly those induced by human immunodeficiency virus (HIV) infection. We investigated the clinicopathological features of PBL at a single institute in Taiwan, where HIV infection is rare. Methods: This retrospective chart review identified PBL cases that were treated at a single institute in southern Tai‑ wan between 2008 and 2024. Results: We identified nine patients (four males and five females; median age 71 years). Of the eight patients tested for HIV, only one tested positive. Pathologically, the tumors showed plasmablastic morphology and immunopheno‑ type, and three (33%) cases tested positive for Epstein–Barr virus. Six (67%) patients presented with Stage IV disease, including five (56%) with malignant effusion. Six patients were treated with chemotherapy and the remaining three received only supportive care. During a median follow-up of 10 months, five patients died of progressive disease, two died of unrelated diseases, and two were alive with PBL relapse. Conclusion In Taiwan, PBL constitutes a rare and aggressive clinical condition and is frequently associated with malignant effusion. In contrast to Western patients, the PBL in most patients from Taiwan was unrelated to HIV infection.

Signal detection is a critical task in drug safety regulation. However, it inevitably generates irrelevant or false signals, posing challenges for resource allocation by marketing authorization holders. To reasonably assess these signals, different countries have established various principles for prioritizing the evaluation of risk signals. This study systematically compares these principles and finds that the U.S. Food and Drug Administration(FDA) focuses on practical issues, such as identifying drug confusion or drug interactions. However, China's Good Pharmacovigilance Practices and the European Medicines Agency(EMA) emphasize a comprehensive evaluation framework. The Council for International Organizations of Medical Sciences(CIOMS) emphasizes the consistency of multiple data sources, highlighting the reliability of signal evaluation. China practices a multidisciplinary approach combining traditional Chinese and western medicine, and the risk signals related to traditional Chinese medicine(TCM) have unique characteristics, including complex components, cumulative toxicity, specific theoretical foundations, and drug interactions. The different priorities in risk signal evaluation principles across countries suggest that China should strengthen clinical trial research, emphasize corroboration with evidence of multiple sources, and pay particular attention to the risks of drug interactions in the TCM regulatory science. Establishing the risk signal prioritization principles that align with the characteristics of TCM enables more precise and efficient scientific regulation of TCM.
