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.

Background: Influenza A virus (IAV) is a negative-sense RNA virus of the Orthomyxoviridae family and is the etiological agent of a highly contagious acute respiratory disease that can lead to acute lung injury. Objective: To elucidate the molecular mechanisms of IAV infection, an integrative research approach combining gene expression profiling, multinetwork analysis, and in vivo experimental validations was employed. Methods: First, a series of network-based analyses were performed, including protein-protein interaction network construction, weighted gene co-expression network analysis, and subsequent gene set enrichment analysis, to identify the major underlying mechanisms of IAV infection. Following gene expression analysis, core targets, both direct and indirect regulators, were screened. An IAV (H1N1) strain A/PR/8/34-induced acute lung injury mouse model was constructed for in vivo validations. Batch one included two groups to evaluate findings from the multi-network analysis: Mock (n = 10; 5 males and 5 females) and IAV (n = 10; 5 males and 5 females). Batch two included three groups to assess the role of toll-like receptor 3 (TLR3) in IAV infection: Mock (n = 6; 3 males and 3 females), IAV (n = 6; 3 males and 3 females), and TLR3 inhibitor (n = 6; 3 males and 3 females). Body weight was measured on days 0, 3, and 5 after infection. On day 5, lung tissues were collected to assess viral load and histopathological changes. Key targets were examined using enzyme-linked immunosorbent assay, Western blotting, and immunofluorescence staining, both in sera and lung tissues. Results: IAV infection was significantly associated with dysregulation of the immune-inflammation system, such as the LTR, nucle-otide-binding oligomerization domain-(NOD) like receptor, retinoic acid-inducible gene I-like receptor, and nuclear factor kappa-B signaling pathways. Gene set enrichment analysis further indicated that the TLR and necroptosis signaling pathways played crucial roles in the progression of IAV infection (TLR signaling pathway normalized enrichment score = 2.3941, P = 1.00 × 10 −10; necroptosis normalized enrichment score = 1.9421, P = 6.21 × 10 −7). Among the core targets, TLR3 and mixed lineage kinase domain-like protein (MLKL) may regulate gene expression at the transcriptional level (all P < 0.05). In vivo validation using an IAV (PR8) infected acute lung injury mouse model demonstrated increased viral load and lung index, alveolar structural damage, and inflammatory cell infiltration. Immunofluorescence staining exhibited large gaps in Lamin B1 staining and breaches in Emerin signals following IAV-PR8 infection. Expression levels of TLR3, p-receptor-interacting serine/threonine-protein kinase 3 (RIPK3)/RIPK3, and p-mixed lineage kinase domain-like protein (MLKL)/MLKL proteins in lung tissues, as well as proinflammatory factors and mediators in sera, were significantly elevated after IAV infection. Moreover, enhanced neutrophil infiltration (myeloperoxidase) and citrullinated histone H3 (a neutrophil extracellular trap-specific marker), both established indicators of neutrophil extracellular trap formation, were observed. Notably, treatment with a TLR3 inhibitor significantly ameliorated IAV-induced acute lung injury by regulating necroptosis-related targets. Conclusion: Our study provides network-based in vivo evidence that TLR3-receptor-interacting serine/threonine-protein kinase 3-MLKL-mediated necroptosis may underlie IAV-induced acute lung injury and could serve as a potential therapeutic target in severe influenza cases.

Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

Benign prostatic hyperplasia (BPH) is a common chronic progressive disease in middle-aged and elderly men, characterized by prostate enlargement and bladder outlet obstruction, leading to symptoms such as frequent urination, urgency, and difficulty urinating. The pathogenesis of BPH involves factors such as aging, hormonal metabolic abnormalities, inflammatory responses, and imbalances in cell proliferation and apoptosis. Currently, the main treatment methods for BPH include medication, physical therapy, and surgical intervention. However, medication may cause side effects like sexual dysfunction and hypotension, physical therapy has limited efficacy, and surgery carries risks and postoperative complications. Therefore, there is an urgent need to find safer and more effective treatment options. Traditional Chinese medicine (TCM), with its focus on treatment based on syndrome differentiation and a holistic approach, offers therapeutic advantages through multiple pathways and mechanisms. Recent studies have shown that TCM regulates pathways such as phosphoinositide-3-kinase/protein kinase B (PI3K/Akt), nuclear factor-κB (NF-κB), mitogen-activated protein kinases (MAPK), nuclear factor E2-related factor 2/antioxidant response element (Nrf2/ARE), androgen receptor (AR), transforming growth factor-β (TGF-β)/Smad, and hypoxia-inducible factor-1α/vascular endothelial growth factor (HIF-1α/VEGF) to inhibit oxidative stress and inflammatory response, reduce prostate cell proliferation, and promote apoptosis, thus exerting therapeutic effects. This article summarizes and analyzes the roles of these signaling pathways in the occurrence and development of BPH and the mechanisms of TCM intervention, aiming to provide scientific evidence for clinical treatment and drug development for BPH.

Ergopeptines or their derivatives are widely used for treating neurodegenerative and cerebrovascular diseases. The nonribosomal peptide synthetase-d-lysergyl peptide synthetase A (LPSA) determines ergopeptine formation but the detailed mechanism remains to be elucidated. Here, we characterized two LPSAs from Claviceps purpurea Cp-1 strain through heterologous expression in Aspergillus nidulans feeding with d-lysergic acid. We proved that Cp-LPSA1 catalyzed the formation of ergocornine, α-ergocryptine, and β-ergocryptine, precisely controlled by the substrate specificity of its three modules. Cp-LPSA2 was initially inactive but could be restored to catalyze α-ergosine formation. Using this platform, we validated that P1-LPSA1 and P1-LPSA2 from the reported C. purpurea P1 strain catalyzed ergotamine and α-ergocryptine formation, respectively. Typically, the non-ribosomal peptide codes implicated in every module of the LPSAs were defined and elucidated, in which certain key residues could play a switched role for substrate specificity and product interconversion. By constructing chimeric LPSAs through module assembly, the production of the desired ergopeptines was achieved. Notably, 1.46 mg/L of α-ergocryptine and 1.09 mg/L of ergotamine were produced respectively by mixed-culture of C. paspali No. 24 (fermentation supernatant) and the recombinants of A. nidulans. Our findings provide insights into the biosynthetic mechanism of ergopeptines and lay a foundation for directed ergopeptine biosynthesis.

Triple-negative breast cancer is therapeutically challenging due to the low expression of tumor markers and 'cold' tumor immunosuppressive microenvironment. Here, we present a dual-targeting peptide-drug conjugate (PDC) for tumor inhibition. Our PDC efficiently and selectively delivers cytotoxic Monomethyl Auristatin E (MMAE) into tumor cells via C-X-C chemokine receptor type 4 (CXCR4) and folate receptor 1 (FOLR1) for synergistic inhibition of growth and metastasis. Our results show that the dual-targeting PDC has potent antitumor activity in cultured human cells and several murine transplanted tumor models without apparent toxicity. The combination of dual-targeting PDC and radiotherapy modulates the tumor immunosuppressive microenvironment by increasing CD8+ T cell infiltration and attenuating the proportion of myeloid-derived suppressor and regulatory T cells. Therefore, our dual-targeting PDC represents a promising new strategy for cancer therapy that rebalances the immune system and promotes tumor regression.

The KCNQ potassium channels play a crucial role in modulating neural excitability, and their dysfunction is closely associated with epileptic disorders. While variants in KCNQ2 have been extensively studied, KCNQ3-related disorders have rarely been reported. With advances in next-generation sequencing technologies, an increasing number of cases of KCNQ3-related disorders have been identified. However, the correlation between genotype and phenotype remains poorly understood. In this study, we established a variant library consisting of 24 missense mutations in KCNQ3 and introduced these mutations into three different template types: KCNQ3, KCNQ3-A315T (Q3*), and KCNQ3-KCNQ2 tandem (Q3-Q2). We then analyzed the effects of these mutations on the KCNQ3 channel function using patch-clamp recording. The most informative parameter across all three backgrounds was the current density of the mutant channels. The current density patterns in the Q3* and Q3-Q2 backgrounds were similar, with most mutations resulting in an almost complete loss of function (LOF), they were concentrated in the pore-forming domain of KCNQ3. In contrast, mutations in the voltage-sensing domain or C-terminus did not show significant differences from the wild-type channel. Interestingly, these LOF mutations were typically associated with self-limited familial neonatal epilepsy, while neurodevelopmental disorders (NDD) were more closely associated with mutations that did not significantly differ from the wild-type. V1/2, another important parameter of the electrophysiological properties, could not be accurately determined in the majority of KCNQ3 mutations due to its nearly complete LOF in the Q3* and Q3-Q2 backgrounds. Intriguingly, the V1/2 of functional mutations were primarily leftward shifted, indicating a gain-of-function (GOF) effect, which was typically associated with NDD. In addition to previously reported mutations, we identified G553R as a novel GOF mutation. In the co-transfection background, parameters such as V1/2 could be determined, but the dysfunctional effects of these mutations were mitigated by the co-expression of wild-type KCNQ3 and KCNQ2 subunits, resulting in no significant differences between most mutations and the wild-type channel. Furthermore, we applied KCNQ modulators to reverse the electrophysiological abnormalities caused by KCNQ3 variants. The LOF mutations were reversed by the application of Pynegabine (HN37), a KCNQ opener, while the GOF mutation responded well to Amitriptyline (AMI), a KCNQ inhibitor. These findings provide essential insights into the pathogenic mechanisms underlying KCNQ3-related disorders and may inform clinical decision-making.

ObjectiveTo explore the correlation between the occurrence of cardiovascular events in rheumatoid arthritis(RA) and traditional Chinese medicine(TCM) syndrome. MethodsThe cross-sectional study selected 6713 RA patients from 122 centres nationwide, in which general information such as name, gender, age, height, body weight, and course of disease were collected by completing a questionnaire; patients were classified into eight types of syndrome according to the information of their four examinations,i.e. wind-dampness obstruction syndrome, cold-dampness obstruction syndrome, dampness-heat obstruction syndrome, phlegm-stasis obstruction syndrome, stasis-blood obstructing collateral syndrome, qi-blood deficiency syndrome, liver-kidney insufficiency syndrome, and qi-yin deficiency syndrome. According to the occurrence of cardiovascular events, they were divided into the occurrence group and the non-occurrence group, and the condition assessment data and laboratory examination indexes were recorded. The test of difference between groups was used to analyse the possible risk factors for the occurrence of RA cardiovascular events, and binary logistic regression was used to analyse the correlation between TCM syndromes and RA cardiovascular events. ResultsA total of 6713 RA patients were included, including 256 cases in occurrence group and 6457 in non-occurrence group. There was no statistically significant difference between groups in terms of height, gender, insomnia, appetite, white blood cell(WBC), hemoglobin(HGB), platelets(PLT), rheumatoid factor(RF), anti-cyclic peptide containing citrulline(CCP), alanine aminotransferase(ALT), aspartate aminotransferase(AST), γ-glutamyl transpeptidase(GGT), urea creatinine(CREA), and glucose(GLU)(P>0.05). The TCM syndromes between groups showed significant statistic differences(P<0.05). Patients in occurrence group had longer disease duration, heavier body weight, and older age; more severe conditions such as disease activity(DAS-28), number of painful joints(TJC), number of swollen joints(SJC), health questionnaire scores(HAQ), visual analog scores(VAS), restlessness, and fatigue; higher blood sedimentation rate(ESR), low-density lipoprotein(LDL-C), triglyceride(TG), total cholesterol(TC), D-Dimer, and lower high-density lipoprotein(HDL-C)(P<0.05). The distribution of syndrome types showed that dampness-heat obstruction syndrome accounted for the largest proportion of patients in both groups and was higher in RA cardiovascular events. Logistic regression analysis showed that the occurrence of RA cardiovascular events was strongly associated with dampness-heat obstruction syndrome[OR=5.937, 95%CI (4.434, 7.949), P<0.001]. ConclusionThe occurrence of RA cardiovascular events were associated with TCM syndromes, and the probability of cardiovascular events in the RA patients with dampness-heat obstruction syndrome was 5.937 times higher than patients with other TCM syndromes.
