The disease-syndrome combination animal model in traditional Chinese medicine (TCM) andrology serves as an important bridge linking TCM theory with modern medical research, providing a key experimental platform for elucidating the 'syndrome-disease' correlation mechanism in male-specific diseases and for screening effective prescriptions. This article reviews recent progress in animal model research on common TCM andrological diseases, including prostatic diseases, sexual dysfunction, and male infertility, with a focus on analyzing the application, advantages, and disadvantages of various modeling strategies, such as immune induction, hormonal intervention, and multi-factor combination across different syndrome types. However, despite breakthroughs in model construction techniques, current research still faces several challenges, including insufficient standardization of syndrome differentiation and difficulties in quantifying TCM-specific indicators. Future studies need to optimize model evaluation systems by integrating modern technologies, in order to promote the standardization and internationalization of TCM andrology research.

This paper has summarized current studies on retinitis pigmentosa (RP) from two perspectives, which were disease mechanism insights from western medicine, and etiology, pathogenesis and therapeutic principles in traditional Chinese medicine (TCM). From the perspective of western medicine, the understanding of RP has evolved from an early single-factor explanation focusing on pathogenic gene mutations to a more comprehensive, multifactorial model involving genetic abnormalities, photoreceptor cell degeneration, retinal pigment epithelium dysfunction, oxidative stress, inflammatory responses, microenvironmental imbalance, and vascular insufficiency. In TCM, RP is considered to be a disorder manifested in the eyes but rooted in dysfunction of the zang-fu (脏腑) organs. Its pathogenesis is primarily associated with congenital insufficiency, liver-kidney depletion, impaired spleen function of transportation and transformation, and stasis obstructing the meridians. The core pathological mechanism can be summarized as "deficiency complicated by stasis", emphasizing holistic imbalance, dynamic disease progression, and syndrome differentiation and treatment. The differences and complementarities between the two medical systems in understanding disease progression are further discussed. RP is proposed to be more appropriately regarded as a complex disease characterized by long-term progression, stage-dependent evolution, and persistent decompensation. Western medicine contributes to elucidating the molecular mechanisms underlying RP and provides the foundation for targeted therapeutic interventions, whereas TCM offers a holistic perspective for understanding disease evolution through the assessment of overall functional status, disease-stage stratification, and long-term syndrome-based regulation.

Objective:To investigate the expression characteristics of the SLFN11 gene in pancreatic cancer and its relationship with cis-diamminedichloroplatinum(DDP)resistance.Methods:This study analyzed multiple publicly available datasets, including GSE207611, GSE186205, GSE73978, GSE217845, and GSE238163 from the gene expression omnibus(GEO)datasets.These datasets comprise gene expression data and single-cell sequencing data from pancreatic cancer cell lines and patients, which were utilized to examine the expression characteristics of the SLFN11 gene and its association with cisplatin resistance.Receiver operating characteristic (ROC) curves were generated, and the area under the curve (AUC) value along with the confidence interval ( CI) were calculated.Additionally, Kaplan-Meier survival analysis and single-cell RNA sequencing(scRNA-seq)data analysis were conducted. Results:The differential expression of the SLFN11 gene between tumor and adjacent normal tissues was statistically significant( P<0.05). The AUC value for SLFN11 in diagnosing pancreatic cancer was 0.761.SLFN11, along with its associated genes PTN and SLC15A3, collectively influenced the survival of pancreatic cancer patients.Results from single-cell sequencing demonstrated high expression of SLFN11 in mesenchymal stem cells. Conclusions:The SLFN11 gene demonstrates significant diagnostic and prognostic value in pancreatic cancer and may play a role in the mechanism of cisplatin resistance.

Adenoid cystic carcinoma(ACC)of the cervix is a rare and highly aggressive subtype of cervical cancer,accounting for less than 1%of all cervical cancer cases.ACC predominantly affects postmenopausal women over the age of 60,with postmenopausal vaginal bleeding being the most common symptom.Diagnosis of ACC primarily relies on histopathological examination and immunohistochemical analysis.Although there is currently no standard treatment protocol,surgical resection combined with radiotherapy or concurrent chemoradiotherapy is considered to be an effective approach.However,the effectiveness is limited,particularly in advanced cases,which generally have a poor prognosis.The treatment and prognosis of ACC are closely related to tumor staging,perineural invasion,and margin status.This paper discusses the clinical data and follow-up of six ACC patients treated at our institution,and goes through a literature review,examines its clinical features and treatment outcomes,underscores the critical importance of early diagnosis and individualized treatment.

Kv1.3,a voltage-gated potassium channel,is highly expressed in T lymphocytes,the nervous system,and vascular smooth muscle cells.It plays a critical role in membrane excitability and electrical signal transduction,serving as an important target for studying T-cell function and providing a promising direction for developing therapeutics against autoimmune and inflammatory diseases.Therefore,the de-velopment of specific inhibitors of Kv1.3 channel has emerged as a novel therapeutic strategy for these disorders.In this study,we isolated and purified a novel Kv1.3-inhibitory peptide toxin,LmKTx13,from the venom of the scorpion Lychas mucronatus using reversed-phase high-performance liquid chroma-tography(RP-HPLC).LmKTx13 consists of 38 amino acid residues,including six cysteines that form three disulfide bonds.Whole-cell patch-clamp recordings revealed that LmKTx13 potently inhibited Kv1.3 with an IC50 of 7.92±3.0 nmol/L.Selectivity analysis showed that 2 μmol/L LmKTx13 also in-hibited Kv1.2 and Kv1.7,but exhibited no significant effects on other potassium channel subtypes or voltage-gated sodium channels.Further investigation into the mechanism demonstrated that LmKTx13 acts as a pore-blocking inhibitor of Kv1.3.By analyzing the effects of LmKTx13 on Kv1.3 channel gating ki-netics and performing sequence alignment of the pore regions of Kv1.3 and Kv1.5,we constructed site-directed mutants and identified the pore region of Kv1.3 as the critical binding site for LmKTx13.Key residues involved in the interaction included T425,G427,and H451.In summary,we discovered a no-vel pore-blocking Kv1.3 inhibitor,LmKTx13,from L.mucronatus venom,which exhibits high affinity and selectivity for Kv1.3.These findings highlight its potential as a potential lead molecule for developing Kv1.3-targeted therapeutics.

Objective:To investigate the role and molecular mechanism of dual-specificity phosphatase 26(DUSP26)in the proliferation,migration and invasion of lung adenocarcinoma(LUAD)A549 cells.Methods:The expression profile of DUSP26 was retrieved from the GEPIA2 tumor database,and its differential expression in LUAD tissues and normal human lung tissues were analyzed.Twelve pairs of LUAD tissue and paracancerous tissue surgically resected at Pingxiang People's Hospital between October 2022 and October 2023 were collected.The difference in DUSP26 expression between LUAD tissues and paracancerous tissues was analyzed using immunohistochemical(IHC)staining and Western blotting(WB).Additionally,the expression of DUSP26 in four LUAD cells(A549,SK-LU-1,Calu-3,H1299)and two normal bronchial epithelial cells(BEAS-2B,HBEC)was detected using WB method.A549 cells stably overexpressing DUSP26(DUSP26-OE)or corresponding negative control(DUSP26-OENC)were constructed via lentiviral transfection.The effects of DUSP26 overexpression on cell proliferation,migration and invasion were detected using colony formation,scratch assay,and Transwell chamber assay,respectively.The expression levels of TGF-β1/SMAD2/3 pathway-and epithelial-mesenchymal transition(EMT)-related proteins were detected using WB method,and the expression levels of Ki-67 and cyclin D1 in cells were detected by immunofluorescence staining.Rescue experiments were conducted by adding 5 ng/mL recombinant TGF-β1.A nude mouse xenograft model was established using A549 cells to observe the effect of DUSP26 overexpression on the in vivo growth of transplanted tumors.The expression levels of TGF-β1/SMAD2/3 pathway-and EMT-related proteins in transplanted tumor tissues were assessed using WB method,and the expression levels of Ki-67 and cyclin D1 in transplanted tumor tissues were detected using immunofluorescence staining.Results:DUSP26 expression was downregulated in both LUAD tissues and cells(P<0.05,P<0.01,P<0.001 or P<0.000 1).Compared with the DUSP26-OENC group,the DUSP26-OE group showed significantly reduced proliferation,migration and invasion of A549 cells(P<0.01 or P<0.001).Furthermore,the protein levels of TGF-β1,p-SMAD2/3,vimentin,N-cadherin,snail,Ki-67,and cyclin D1 were significantly reduced(P<0.01,P<0.001 or P<0.000 1),while E-cadherin level was increased in the DUSP26-OE group(P<0.000 1).The addition of 5 ng/mL TGF-β1 recombinant protein partially reversed the effects of DUSP26 overexpression in vitro experiments.The nude mice A549 cell xenograft model was successfully constructed.The growth rate of transplanted tumors was significantly slower in the DUSP26-OE group,with reduced volume and mass(all P<0.001).The protein levels of TGF-β1,p-SMAD2/3,vimentin,N-cadherin,snail,Ki-67,and cyclin D1 in the transplanted tumor tissues were all reduced(P<0.01 or P<0.001),while E-cadherin level was increased(P<0.000 1).Conclusion:DUSP26 is downregulated in both LUAD tissues and cells.Upregulation of DUSP26 suppresses the proliferation,migration and invasion of A549 cells by inhibiting the TGF-β1/SMAD2/3 signaling pathway.
