Methods: A H22 liver cancer ascites mouse model was established by intraperitoneally injecting H22 liver cancer cells. Mice were randomly divided into the model group, the Ganfule group (1.35 g/kg), the fluorouracil group (50 mg/kg i.p), the Qinggan Huayu granule groups at low(0.67 g/kg), medium (1.34 g/kg), and high (2.68 g/kg) doses. Then the mice were administered continuously for 10 days and body weight and abdominal circumference were monitored every 3 days. On day 11, eight rats in each group were randomly selected for dissection to detect the amount of peritoneal water, peritoneal permeability and histopathological changes. The remaining mice were observed for survival. In addition, the vascular endothelial growth factor A (VEGFA) and vascular endothelial growth factor receptor 2 (VEGFR2) were determined by Western blotting. Results: Compared with the model group, the weight growth of mice in the fluorouracil group and the medium-dose and high-dose Qinggan Huayu granule groups was slower (P < 0.05). Moreover, the abdominal circumference of mice in each treatment group was increased slowly. There were significant differences in abdominal circumference between the fluorouracil group, the medium-dose group and the control group from day 6 (P < 0.05) while the abdominal circumference of the high dose group was significantly smaller than that of the control group from day 12 (P < 0.05). Moreover, compared with the model group, the amount of ascites in the medium- and high-dose Qinggan Huayu granule groups was decreased significantly (P < 0.05). The optical density value of ascites supernatant in medium- and high-dose Qinggan Huayu granule group and the fluorouracil group decreased significantly (P < 0.05) and the survival period of the medium-dose Qinggan Huayu granule group and the fluorouracil group was prolonged prominently (P < 0.05). There was no significant difference in the low-dose Qinggan Huayu granule group and the Ganfule group. Peritoneal histopathological assay showed more complete peritoneal structure, less edema and less angiogenesis of the peritoneum in the fluorouracil group and the medium- and high-dose Qinggan Huayu granule group, which was better than that of the Ganfule group and the low-dose group. Compared with the model group, the expressions of VEGFA and VEGFR2 in the medium-dose Qinggan Huayu granule group decreased significantly (P < 0.05, P < 0.01). Conclusion: Qinggan Huayu granule can inhibit ascites production in the mice model with H22 liver cancer ascites tumor, prolong the survival of mice, and reduce peritoneal permeability and suppress the increase of peritoneal neovascularization. The mechanism may be related to the inhibition of VEGF /VEGFR pathway.

Methods: 10 C57BL /6J mice were used as blank group, and 20 ApoE-/- mice were randomly divided into AS group and AS+CUMS group. After one week of adaptive feeding, except for the blank group, the other two groups were fed with high fat diet. Meanwhile, the AS+CUMS group was given chronic unpredictable mild stress. The model was evaluated after 16 weeks of modeling. During the experiment, the body weight, food intake, excitability, hair color and other general morphology of mice in each group were observed and recorded. Behavioral indexes (Sucrose preference tests and Open Field test) were detected in each group.The levels of 5-hydroxytryptamine (5-HT) and hypothalamic-pituitary-adrenal (HPA) axis hormones, including adrenocorticotropin (ACTH) and corticosterone (CORT), were detected by ELISA. Serum lipid levels, including total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C), were detected by ELISA. HE staining was used to observe the pathological condition of aorta. Results: Compared with blank group, the excitability and food intake of AS+CUMS group were significantly decreased. There were no significant differences in sugar water consumption and activity capacity of mice in AS group, while sugar water consumption and activity capacity of mice in AS+CUMS group were significantly decreased (P < 0.01). The serum 5-HT levels in AS group and AS+CUMS group were decreased, and the levels of ACTH and CORT in AS+CUMS group were significantly decreased (P < 0.01), and the levels of ACTH and CORT in AS+CUMS group were significantly increased (P < 0.01). The serum TC, TG and LDL-C levels of mice in AS group and AS+CUMS group were significantly increased (P < 0.01), while the HDL-C level of mice in both groups was significantly decreased (P < 0.01). HE staining results showed that the area and degree of plaques in the active vascular lumen of AS group and AS+CUMS group were larger and heavier. Conclusion: High fat feeding combined with CUMS was successful in establishing a mouse model of emotional disorder combined with atherosclerosis.

Methods: The cytotoxicity, glucose consumption and intracellular triglyceride assay were been detected by commercial kits. The western blots were used to detection the associated protein levels after CGA treatment, and the inhibiter blocking experiments were also be done. In vivo experiment, the fasting blood-glucose, lipid metabolism, liver function, insulin resistance, glucose tolerance, and pathological change were assessed on streptozocin induced diabetic mice. Results: We found that CGA exhibited no cytotoxicity at concentrations of 100μM, it caused a significant increasing of glucose consumption and reducing of the PA-BSA induced intracellular TG level on HepG2 cells at 50μM and 100μM treatment, CGA exhibited up-regulating the level of p-AMPK (Thr172) and p-ACC (Ser79) in dose-dependent manners in vitro and in vivo. The stimulating activities of CGA on AMPK were completely blocked by compound c (CC) on HepG2 cells. And the efficacies of CGA on glucose consumption and intracellular TG accumulation were also completely blocked by CC pretreatment. The CGA also exhibited potent anti-diabetic effects with hypoglycemic activity, improve insulin resistance and glucose tolerance, regulate glucose and lipid metabolism and protect the liver function in vivo. Conclusion: Our results suggested that CGA can regulate glucose and lipid metabolism by AMPK activation, and exhibit potent anti-hyperglycemic effect in streptozocin induced diabetes mice, and may be used as a potential effective anti-diabetes drug.

Method: Co-culture model of colon cancer cell line SW480 or human umbilical cord mesenchymal stem cells (hUC-MSCs) with human normal colon epithelial cells (NCM460) was established. Morphological changes of NCM460 after co-culture were evaluated by microscopic observation, and migration ability of NCM460 was measured by wound healing and Transwell assay. Meanwhile, Western blot was used to detect the EMT markers of NCM460. Results: There was no significant change in cell morphology of NCM460. Transwell assay results showed that when hUC-MSC or SW480 were co-cultured with NCM460, there is a trend of enhancement of the migration ability of NCM460, and the expression of Vimentin was up-regulated to some extent (P<0.05), E-cadherin and wound healing ability were not significantly changed (P>0.05).When NCM460 were cocultured with MSCs and SW480 at the same time, NCM460's wound healing ability and migration ability were significantly enhanced, meanwhile Vimentin protein expression was significantly up-regulated and E-cadherin protein was significantly down-regulated significantly (P<0.05). Conclusion: Colon cancer cells can increase the migration ability of normal colon epithelial cells and upregulate the expression of EMT markers. Mesenchymal stem cells may play a role in this process.

Methods: The effective components of Danshen and chuanxiong were searched in the TCM System Pharmacology Database (TCMSP), and the drug targets were searched in the Swiss Target Prediction database; in the Disease-Gene Database (DisGeNET) ) Search for angiogenesis-promoting and inhibiting angiogenesis targets; use the protein interaction database (STRING) database and Cytoscape software to analyze the network core targets; use the DAVID database to enrich the drug-disease target intersection for GO and KEGG; RT-qPCR experiments verified the effect of luteolin on MMP9 gene expression; in vitro tube formation experiments analyzed the effect of luteolin on endothelial cell neovascularization. Results: After analysis, it is concluded that Danshen has 10 active ingredients and 50 angiogenesis targets; Chuanxiong has 2 active ingredients and 4 angiogenesis targets. The intersection of drug-taking targets yielded 9 targets, including AR, PARP1, MMP9, MMP2, MMP12, AKR1B10, ABCC1, CDK6, and STAT3.After analyzing the active ingredient-target network graph of Danshen/Chuanxiong, it was concluded that luteolin is the key chemical ingredient. After protein interaction (PPI) analysis, the results showed that MMP9 is the core target. The KEGG pathway is mainly enriched in 5 signaling pathways, the most important pathway is cancer-related pathways. There are 22 main biological processes of GO, which mainly involve collagen catabolism, protein extracellular matrix, metal endopeptidase activity, etc. The preliminary analysis of tubule formation experiment shows that luteolin inhibits angiogenesis and down-regulates the expression of MMP9 gene. Conclusion : Luteolin, the key chemical component of the Danshen-Ligusticum chuanxiong drug pair, inhibits angiogenesis by regulating the MMP9 target, and develops the reverse regulation of angiogenesis for the traditional Chinese medicine for promoting blood circulation and removing blood stasis on the basis of the known treatment of ischemic diseases. Provide a new perspective and theoretical basis for the use of Danshen and Chuanxiong medicine in clinical cancer patients. Reveal the material basis and mechanism of angiogenesis effect of Danshen-chuanxiong herb-partners.

    查看更多>>摘要:The incidence of liver fibrosis is increasing worldwide, and if left untreated, it will later develop into cirrhosis with a high mortality rate. In this paper, the activation pathway and related mechanism of stellate cells in liver fibrosis are introduced, and some current therapeutic methods are summarized. These results suggest that stellate cells play an important role in liver fibrosis, and targeted therapy for the purpose of inhibiting the activation of stellate cells and inducing their apoptosis is expected to be an effective regimen to reverse liver fibrosis. However, there are some problems such as insufficient in-depth study of related mechanisms and imperfect experiments. In future animal experiments and clinical trials, more studies can be carried out to provide high-quality protocols for the treatment of liver fibrosis.
