ObjectiveTo investigate the effect of the herb pair Cuscutae Semen-Lycii Fructus on oxidative stress-induced blood-testis barrier dysfunction and spermatogenesis in the rat model of oligoasthenozoospermia （OAS） and decipher the mechanism based on the silent information regulator 1 （SIRT1）/nuclear factor erythroid 2-related factor 2 （Nrf2） signaling pathway. MethodsThirty-five male SD rats were randomized into a blank group （n=7） and a modeling group （n=28）. The OAS model was established by gavage of hydrocortisone aqueous solution combined with single factor electrical stimulation. The modeled rats were randomly assigned into the following groups： model， Cuscutae Semen-Lycii Fructus granules （3.2 g·kg^-1）， Cuscutae Semen-Lycii Fructus total flavonoids （0.34 g·kg^-1）， and L-carnitine （0.38 g·kg^-1）， and treated for 4 weeks. The sperm quality of rats was assessed by an automatic sperm analyzer. The levels of superoxide dismutase （SOD）， malondialdehyde （MAD）， and glutathione peroxidase （GSH-Px） in the testicular tissue were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was employed to reveal the pathological changes in the testicular tissue and score the spermatogenic function. Transmission electron microscopy was employed to observe the ultrastructural changes of Sertoli cells. Western blot and Real-time PCR were employed to determine the protein and mRNA levels， respectively， of SIRT1， Nrf2， Occludin， zonula occludens-1 （ZO-1）， connexin 43 （CX43）， and β-catenin. ResultsCompared with the blank group， the model group showed decreased total sperm count and motility （P<0.05， P<0.01）， obvious damage in the testicular tissue and blood-testis barrier structure， reduced score of spermatogenic function （P<0.01）， declined levels of GSH-Px and SOD in the testicular tissue （P<0.05）， elevated level of MDA， and down-regulated protein levels of SIRT1， Nrf2， ZO-1， CX43， β-catenin， and occludin （P<0.05， P<0.01） and mRNA levels of SIRT1， Nrf2， ZO-1， CX43， and β-catenin in the testicular tissue （P<0.05， P<0.01）. After treatment， the testicular tissue， blood-testis barrier structure， and score of spermatogenic function （P<0.01） were improved in the Cuscutae Semen-Lycii Fructus granules group， Cuscutae Semen-Lycii Fructus total flavonoids group， and L-carnitine group. Compared with the model group， the treatment groups presented lowered levels of GSH-Px and SOD （P<0.05， P<0.01）， and the Cuscutae Semen-Lycii Fructus granule group showed a decline in MDA level. The protein and mRNA levels of SIRT1， Nrf2， ZO-1， CX43， β-catenin， and occludin were up-regulated in the Cuscutae Semen-Lycii Fructus granules group and total flavonoids group （P<0.05， P<0.01）. ConclusionThe herb pair Cuscutae Semen-Lycii Fructus can regulate the SIRT1/Nrf2 pathway to inhibit oxidative stress and alleviate the blood-testis barrier damage， thereby improving the spermatogenic function in the rat model of OAS. Total flavonoids may be the material basis for the therapeutic effect of Cuscutae Semen-Lycii Fructus.

Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Anaplastic lymphoma kinase (ALK) rearranged renal cell carcinoma (ALK-RCC) is an exceedingly rare malignancy, recently classified as a distinct molecular entity in the 5th edition of the WHO classification for urinary and male genital tumors. Due to its non-specific clinical symptoms and diverse histopathological patterns, accurate diagnosis is difficult. This paper reports a case of ALK-RCC with morphology and immunophenotype resembling papillary renal cell carcinoma. After second-generation sequencing, EML4-ALK gene fusion was found, and positive staining for ALK was confirmed by immunohistochemistry subsequently. Following informed consent from the patient, targeted therapy with crizotinib was initiated. During a 17-month follow-up period, no recurrence or metastasis was observed.

Objective To investigate the inhibitory effects and mechanisms of α-hederin,an active ingredient in Fruc-tus Akebiae,on hepatocellular carcinoma(HCC)cells.Methods HCC cells were divided into four groups and treated with α-hederin(0,10,20,and 30 μmol·L-1)for 24 h and 48 h,respectively.MTT assays were used to detect the cell proliferation rate,flow cytometry(FCM)was used to detect the apoptotic rate,transcriptomics was used to screen signaling pathways in α-hederin-treated HCC cells,RNA interference was exploited to verify the underlying signaling pathway,and real-time quantitative PCR(qRT-PCR)and Western blotting(WB)were used to detect expression changes of the mRNA and protein of TP53(p53),PMAIP1(Noxa),and apoptosis-associated proteins,Caspase9 and Caspase3.Results α-Hederin induced apoptosis by activa-ting apoptosis-associated proteins,PARP,Caspase9 and Caspase3.Transcriptomics,qRT-PCR,and WB results also showed that α-hederin increased the mRNA and protein expression of p53 and Noxa.Furthermore,α-hederin inhibited the protein degradation of p53 and Noxa,reversing the apoptosis decrease in p53/Noxa siRNA-knocked-down HCC cells.In vivo results showed that α-hederin inhibited the growth of HCC tumors.Conclusion α-hederin may induce the apoptosis of HCC cells by activating and stabilizing the p53/Noxa signaling pathway.

This paper summarized Professor ZHANG Farong's experience in the staged treatment of hyperthyroi-dism with triangular medicine. It is considered that "pathogenic heat consuming and damaging qi-yin" is the key pathogenesis of hyperthyroidism. In the early stage， liver constraint transforms into fire， and then pathogenic heat becomes exuberant inside， consuming qi and damaging yin. In the middle stage， the fire and heat are intense， and phlegm and stasis are binded， when qi and yin are initially depleted. In the late stage， both qi and yin are deficient， and as the disease lasts for a long time， the kidneys are affected， resulting in liver and kidney depletion. For treatment， it is suggested to put focus on rectifying healthy qi and dispelling pathogen， protecting qi and yin， and treating the disease by stages based on syndrome differentiation， and eight groups of triangular medicines have been summarized according to the characteristics of pathogenesis in different periods. In the early stage， the combination of Chaihu （Radix Bupleuri）， Xiangfu （Rhizoma Cyperi） and Yujin （Radix Curcumae） is used to soothe the liver and resolve constraint， and the combination of Longdancao （Radix et Rhizoma Gentianae）， Huangqin （Radix Scutellariae） and Zhizi （Fructus Gardeniae） is recommended to clear liver and drain fire. In the middle stage， the combination of Xiakucao （Spica Prunellae）， Baihua Sheshecao （Herba Hedyotis Diffusae） and Banzhilian （Herba Scutellariae Barbatae） is used to clear heat and dissipate masses， and the combination of Huangyaozi （Rhizoma Dioscoreae bulbiferae）， Maozhuacao （Ranunculus Ternatus） and Shancigu （Asarum Sagittarioides） can dissolve phlegm and dissipate masses， and the combination of Danshen （Radix et Rhizoma Salviae Miltiorrhizae）， Xuanshen （Radix Scrophulariae） and Kushen （Radix Sophorae Flavescentis） can invigorate blood and eliminate goiter. In the late stage， the combination of Dangshen （Radix Codonopsis）， Baizhu （Rhizoma Atractylodis Macrocephalae） and Yiyiren （Semen Coicis） can fortify spleen and replenish qi， and the combination of Maidong （Radix Ophiopogonis）， Beishashen （Radix Glehniae） and Wuweizi （Fructus Schisandrae Chinensis） is used to nourish yin and calm heart， while the combination of Huangqi （Radix Astragali）， Huangjing （Rhizoma Polygonati） and Diyu （Radix Sanguisorbae） is used to nourish yin and replenish kidneys.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Objective To investigate the risk factors for biliary stricture within two years after orthotopic liver transplantation,and analyze the survival.Methods A retrospective analysis was performed for the data of 495 patients who underwent liver transplantation at Liver Transplantation Center of The First Hospital of Jilin University from January 2014 to January 2022,and according to the presence or absence of biliary stricture within two years after liver transplantation,the 495 patients were divided into stricture group with 89 patients and non-stricture group with 406 patients.The risk factors for biliary stricture and prognosis were analyzed.The independent-samples t-test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.Univariate and multivariate Cox regression analyses were used for the analysis of risk factors,and the Kaplan-Meier method was used for survival analysis.Results Recipient sex(hazard ratio[HR]=1.808,95%confidence interval[CI]:1.055-3.098,P=0.031),preoperative total bilirubin of the recipient(HR=1.002,95%CI:1.001-1.003,P=0.001),cold ischemia time(HR=1.003,95%CI:1.001-1.005,P=0.007),history of abdominal surgery for the recipient(HR=3.851,95%CI:2.273-6.524,P<0.001),and mismatch of donor-recipient bile ducts(HR=1.962,95%CI:1.041-3.698,P=0.037)were identified as independent risk factors for biliary stricture within two years after transplantation.The median follow-up time was 4.09 years,and the 1-,3-,and 5-year survival rates were 92.7%,80.5%,and 75.4%,respectively,after liver transplantation.The onset of biliary stricture within two years after liver transplantation had no significant impact on the survival of patients undergoing orthotopic liver transplantation.Conclusion Recipient sex,preoperative total bilirubin of the recipient,cold ischemia time,history of abdominal surgery for the recipient,and mismatch of donor-recipient bile ducts are independent risk factors for biliary stricture within two years after transplantation.The onset of biliary stricture within two years after transplantation does not affect the survival time of patients undergoing orthotopic liver transplantation.
