OBJECTIVE: To investigate the in vivo intervention and relative mechanism of Genistein (GEN) on tumor-associated inflammatory and tumor thrombophilia in lymphoma-bearing mice. METHODS: Forty female Balb/c mice aged 5-6 weeks were injected with murine-derived Pro B-cell lymphoma cell line 38B9 to establish a lymphoma mouse model, which was randomly divided into control group, tumor-bearing group, GEN drug intervention group and cyclophosphamide (CTX）drug intervention group. Histopathologic was used to evaluate the tumorigenesis. Tumor formation was observed, and tumor tissues were collected of HE and immunohistochemical staining. ELISA and flow cytometry were used to detect the expression of inflammatory factors and the changes of thrombus indices in plasma after intervention of GEN and Cyclophosphamide (CTX) respectively. Immunohistochemistry method was used to detect the expression of CD19 in tomor tissues of tummor bearing mice. RESULTS: After 14 days of tumor bearing, the mice were tumorigenic. The lymphoma cells were diffusely distributed in the tumor tissue and the expression of CD19 in the tumor tissue was positive. The inflammatory factors such as IL-6, NETs and CLEC-2, and thrombotic indices such as TF, FIB and D-D in lymphoma-bearing mice were significantly higher than those before tumor-injection and lower than those after drug-intervention (all P<0.05). The levels of CLEC-2 and D-D in GEN group were significantly lower than those in CTX group (P<0.05). CONCLUSION Tumor-associated inflammation and thrombophilia exist in lymphoma-bearing mice. GEN shows better anti-inflammatory and anti-thrombotic effects compared with CTX by interfering with tumor inflammatory factors.

OBJECTIVE: To investigate the effect of hydronidone on CCl₄-induced liver fibrosis in rats and explore the possible mechanism. METHODS: Sixty-six male SD rats were randomized into 5 groups, including a control group (n=10), a liver fibrosis model group (n=20), 2 hydronidone dose groups (100 and 250 mg/kg; n=12), and a pirfenidone (250 mg/kg) treatment group (n= 12). Rat models of liver fibrosis were established by subcutaneous injection of CCl₄ in all but the control group. Hydronidone and pirfenidone were given daily at the indicated doses by intragastric administration for 6 weeks. After the treatments, serum samples were collected from the rats for detecting liver function parameters, and hydroxyproline content in the liver tissue was determined. Inflammation and fibrosis in the liver tissue were observed using HE staining and Sirius Red staining. In the cell experiment, human hepatic stellate cell line LX-2 was stimulated with TGF-β1 and treated with hydronidone or pirfenidone, and the expression levels of α-SMA, collagen type I and phosphorylated Smad3, phosphorylated p38, phosphorylated ERK1/2 and phosphorylated Akt were detected with Western blotting. RESULTS: In the rat models of liver fibrosis, treatment with hydronidone obviously improved the liver functions, reduced the content of hydroxyproline in the liver tissue, and significantly alleviated liver fibrosis (P < 0.05). In LX-2 cells, hydronidone dose-dependently decreased the expression levels of α-SMA and collagen type I. In TGF- β1-stimulated cells, the phosphorylation levels of Smad3, P38, ERK, and Akt increased progressively with the extension of the treatment time, but this effect was significantly attenuated by treatment with hydronidone (P < 0.05). CONCLUSION Hydronidone can inhibit the phosphorylation of the proteins in the TGF-β signaling pathway, thereby preventing TGF-β1-mediated activation of hepatic stellate cells, which may be a possible mechanism by which hydronidone alleviates CCl₄-induced liver fibrosis in rats.

This study aimed to evaluate the therapeutic effect of IR-61, a novel mitochondrial heptamethine cyanine dye with antioxidant effects, on diabetes mellitus-induced erectile dysfunction (DMED). Eight-week-old male Sprague-Dawley rats were intraperitoneally injected with streptozotocin (STZ) to induce type 1 diabetes. Eight weeks after STZ injection, all rats were divided into three groups: the control group, DM group, and DM + IR-61 group. In the DM + IR-61 group, the rats were administered IR-61 (1.6 mg kg

Endometriosis is a prevalent chronic disease that affects approximately 6% to 10% of reproductive-aged women. Although numerous researchers have endeavored to explore the etiology of endometriosis over a century, its etiology still remains an enigma. The exploration of pathophysiologic mechanism and novel therapy for endometriosis depends on ideal endometriotic models. In the previous decade, various endometriotic models have been established; therefore, we made a conclusion for available information on these models. This review summarized the common experimental models used in endometriotic studies, including their origins, characteristics, applications, and limitations. Endometriotic models played an important role in studying etiologies and novel treatments of endometriosis during the last decades. Among them, animal models and endometriotic cell lines were viewed as most common studying tools to explore the intrinsic entities of endometriosis. In addition, endometrial organoid also emerged and was regarded as an ideal studying tool for endometriosis research. Different research models collectively complement each other to advance the endometriosis research. The successful establishment of endometrial organoids means that organoids are expected to become an ideal model for studying endometriosis in the future.

OBJECTIVE: To investigate the expression and clinical significance of RhoH gene in bone marrow cells of leukemia patients. METHODS: 31 cases of leukemia and 15 cases of non-tumor as controls were collected. The expression of RhoH in bone marrow cells was detected by real-time quantitative PCR (RQ-PCR). The median expression level of RhoH was used as the cut-off value. The newly diagnosed patients were divided into RhoH high expression group and low expression group. The relationship of different RhoH expression levels with clinical features and prognosis of newly diagnosed patients was analyzed. RESULTS: The mRNA expression of RhoH in the bone marrow cells of 31 cases of leukemia was significantly lower than that in the control group, mRNA expression of RhoH in the ALL group was significantly lower than that in AML group (P＜0.05). Compared with the RhoH high expression group, the proportion of bone marraw blasts and LDH level in the RhoH low expression group was significantly increased (P＜0.05), but there were no significant differences in clinical features such as age, white blood cell count, hemoglobin level, platelets count, PCT and CRP level (P＞0.05). In AML, the recurrence rate after standard chemotherapy in RhoH low expression group was higher than that in high expression group, while the expression of RhoH not correlated with other prognostic genes of AML. In ALL, the recurrence rate in RhoH low expression group was not statistically significant different from that in high expression group. CONCLUSION RhoH may be involved in the genesis of acute leukemia. In AML, RhoH expression negatively correlates with recurrence rate, which can be used as a prognostic indicator independently. In ALL, RhoH may participate in the disease process through other mechanism.
