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.

Colorectal cancer (CRC) is a prevalent malignant tumor of the digestive tract, with a high incidence and high mortality. The majority of patients are diagnosed at the middle or advanced stage, which severely influences and threatens their physical health. Current treatment modalities such as surgery, radiotherapy, and chemotherapy often encounter challenges including metastasis, recurrence, and drug resistance. The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway serves as a classical regulator that regulates physiological processes such as cell cycle, autophagy, apoptosis, and proliferation. Overexpression of this pathway is observed in various tumors. In the context of CRC, the activation of this pathway can facilitate the proliferation, invasion, and migration, inhibit the autophagy and apoptosis, promote the epithelial-mesenchymal transition of CRC cells, enhance angiogenesis within the tumor, and contribute to chemotherapy resistance and radiation resistance in CRC. Traditional Chinese medicine (TCM) treatment can exert an anti-CRC effect by inhibiting this pathway, thereby improving clinical efficacy and safety. This article retrieves relevant research literature published domestically and internationally regarding the regulation of the PI3K/Akt/mTOR signaling pathway by TCM in the treatment of CRC and conducts detailed classification and summary. The active components of TCM include glycosides, flavonoids, alkaloids, terpenoids, polyphenols, and naphthoquinones. The volatile oils and extracts of TCM include Angelicae Sinensis Radix volatile oil, Astragali Radix polysaccharides, Caryophylli Flos extract, Forsythiae Fructus extract, Curcumae Longae Rhizoma extract, and Celastrus orbiculatus extract. The compound formulas of TCM include Banxia Xiexin decoction, Jianpi Qingre Huoxue formula, and Chanling Plaster. Through summary and analysis, it is discovered that the abovementioned TCM can produce effects such as blocking the cell cycle, inducing autophagy and apoptosis, inhibiting angiogenesis, suppressing proliferation and migration, and reversing chemotherapy resistance and radiotherapy resistance by inhibiting the PI3K/Akt/mTOR pathway in CRC cells. TCM holds promise in the research and application of targeting the PI3K/Akt/mTOR signaling pathway for CRC treatment. The summary and conclusion of this article aim to provide references for subsequent research and the development of new drugs.

Objective:To investigate the correlation between liver stiffness and histopathological changes in a rat model of acute hepatitis using virtual touch tissue imaging quantification (VTIQ) technology.Methods:A total of 100 SPF-grade SD rats were randomly divided into 3 groups: control ( n=30), low-dose ( n=35), and high-dose ( n=35) groups. Acute hepatitis models were induced in the low-dose and high-dose groups using 400 mg/kg and 600 mg/kg of Thioacetamide (TAA), respectively. Liver stiffness parameters of the right median lobe and right lobe were measured using VTIQ technology, Mean-H and Mean-L represent the liver lobes with higher and lower liver stiffness measurments, respectively, while Mean represent the average of the measurements from both liver lobes. Comparative analyses of liver stiffness parameters were performed across three groups and between the two lobes of the liver. The correlations between the Mean values of liver stiffness and semi-quantitative histopathological data were investigated. Ten rats were randomly selected from each of the 3 groups to test the repeatability of VTIQ values before and after euthanasia with intraperitoneal anesthesia. Subsequently, 10 rats after euthanasia from each 3 group were randomly chosen to assess the repeatability of VTIQ measurements for inter-observer and intra-observer variabilities. Results:VTIQ results showed statistically significant differences in Mean, Mean-H, and Mean-L among the 3 groups (all P<0.01). The high-dose group had higher measurements compared to the low-dose and control groups, with significant intergroup differences (all P<0.01). Significant differences in Mean-H and Mean-L were observed between the two liver lobes in both low and high-dose groups (all P<0.01). The Mean value showed significant positive correlations with semi-quantitative histopathological data of hepatocellular edema, periportal inflammatory cell infiltration, macrophage proliferation, and bile duct proliferation ( r=0.391, 0.648, 0.577, 0.542; all P<0.01). Multivariate linear regression analysis indicated that hepatocellular edema, eosinophilic change, and bile duct proliferation significantly and positively predicted the Mean value (β=-0.278, -0.196, -0.333; all P<0.05). There were no significant differences of VTIQ measurements befor and after euthanasia (all P>0.05), with repeatability coefficients of 0.166, 0.182, 0.185 for Mean, Mean-H, and Mean-L, respectively. Post-euthanasia, inter- and intra-observer VTIQ differences remained non-significant (all P>0.05), with Mean, Mean-H, Mean-L coefficients of 0.114, 0.194, 0.165 and 0.206, 0.322, 0.268, respectively. Conclusions:VTIQ technology demonstrates potential clinical value in assessing a rat model of acute hepatitis, offering a new perspective for non-invasive evaluation of acute hepatitis. However, its clinical application requires further validation.
