Ethnopharmacological relevance: Qingdu granule (QDG), a traditional Chinese herbal prescription, had antitumor effect on breast cancer. However the underlying mechanism of QDG was unclear. The aim of this study: The present study aimed to investigate whether QDG could inhibit angiogenesis of breast cancer via acting on nuclear factor of activated T-cells (NFAT) signaling pathway. This was implicated in human umbilical vein endothelial cells (HUVECs) in vitro and breast cancer xenograft model in vivo. Materials and methods: The VEGF(165) (15.58 ng/mL) induced human umbilical vein endothelial cells (HUVECs) were treated with serum samples containing tamoxifen (TAM), tacrolimus (FK506), or QDG with three dosages. The migration and canalization capacities of HUVECs were evaluated by transwell migration and tube formation assay. In 72 h-cultured HUVECs, The gene expression, protein amount, and nuclear translocation of NFATc3 were measured. The anti-tumor and anti-angiogenic effects of QDG in vivo were investigated in breast cancer xenograft model. The serum VEGF levels, microvessel density, and protein expressions (immunohistochemistry and western blot) of VEGF, VEGFR2 and NFATc3 were detected. Results: The results showed that, QDG significantly inhibited HUVEC migration and tube formation. It down regulated NFATc3 gene expression, decreased NFATc3 protein amount, and reduced the ratio of NFATc3 nuclear translocation in HUVECs. In breast cancer xenograft model, QDG treatment significantly suppressed tumor growth, inhibited VEGF release, and decreased microvessel density. QDG reduced protein expressions of VEGF, VEGFR2 and NFATc3. Conclusion: The results suggested that QDG showed anti-angiogenic effects of breast cancer both in vitro and in vivo. The mechanism might be partially associated with inhibiting NFAT signaling pathway.

Objective:To investigate the protective effects of baicalin on liver in hepatic precancerous mice induced by diethylnitrosamine(DEN).Methods:Hepatic precancerous model was obtained by administration of DEN through intraperitoneal injection to male mice,and the pharmacologic effects of baicalin were assayed by histopathologic examination and levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),gultathione-S-transferases(GST) and alkaline phosphatase (ALP).Results:The liver functions were serious damaged by administration of DEN,which showed up as morphologic changes and abnormal structure in model mice,such as hver cirrhosis,hepatic fibrosis which divided the liver lobule,liver cell denaturation, hyperplasia,intranuclear inclusions and tendency to atypia,and heavy local infiltration by macrophages was observed,at the same time,enzymatic activities in serum were increased abnormally(P0.05).Situations of mice treated by baicalin were much better,and hepatic fibrosis was decreased,which was failed to divide the liver lobule,and scarce liver cell denaturation,atypical hyperplasia,intranuclear inclusions could be observed.Enzymatic activities in serum were decreased markedly compared with those in model mice(P0.05).Conclusion:Baicalin is partly effective to protect the liver functions in hepatic precancerous mice induced by DEN.

Context: Pharmacokinetics of drug may be altered by abnormal physiological functions in illness, which will affect its pharmacodynamic efficacy in turn.Objective: To assess the preventive effects of tetramethylpyrazine (TMPZ) phosphate on hepatocarcinogenesis and its pharmacokinetic differentiations in model mice.Methods: Diethylnitrosamine (DEN) was adopted to induce hepatic precancerous model in mice through intraperitoneal injection, and prevention efficacy of TMPZ at a dose of 162 mg/kg was examined by liver histological analysis and activities of serum marker enzymes. Pharmacokinetic variations of TMPZ between control and model mice were measured for single oral administration.Results: DEN initiation led to a remarkable increase of serum marker enzymes, and abnormality such as bile canaliculi hyperplasia and presence of tumor cells were observed in liver histopathological examination in model mice, while the control ones revealed normal architecture. Oral treatment of TMPZ resulted in a marked reduction in serum marker enzymes and improvement in liver histopathology compared with model ones. In pharmacokinetic study, values of AUC and T-max of TMPZ became significantly greater with increase of doses in both control and model mice, which elucidated the absorption was enhanced and delayed; meanwhile, its elimination was not affected markedly. When the mice were treated at same dose, the adsorption of TMPZ in model mice was greatly improved than that in control ones, while T-max and MRT had no significant difference.Conclusion: TMPZ was partly effective to protect liver from carcinogenesis initiated by DEN, and hepatic insufficiency could change its pharmacokinetics.

Objective: To confirm the protective effect of curcumin on diethylnitrosamine(DEN)-induced hepatic precancerous lesions in mice.Method: The male mice were randomly divided into four groups.The hepatic precancerous lesions in mice were replicated with DEN(95 mg·kg-1) intraperitoneal administration once a week for 10 weeks,meanwhile curcumin(120.0 mg·kg-1) with or without Rhizoma Dioscoreae(3.03 g·kg-1) was administrated intragastrically once a day to protect the hepatic precancerous lesions.On the 71st day,the blood was collected to detect the hepatic injury biomarkers,and partial liver was fixed to observe the pathological changes.Result: Compared with those in the control mice,the hepatic precancerous lesions in the model mice were confirmed as the alterative and proliferative changes of liver,the proliferative hepatocytes were demonstrated as the atypia similar to hepatic carcinoma,the alterative changes were supported by the elevated activities of serum ALT(195.57±91.56) U·L-1,AST(39.68±24.20) U·L-1 and GST(42.31±8.19)U·L-1.The administration of curcumin relieved the hepatic precancerous lesions significantly(P<0.01),and the combination use of curcumin and Rhizoma Dioscoreae could enhance the effect(P<0.05) in the treatment groups with ALT(82.75±38.54) U·L-1,AST(30.32±7.80) U·L-1and GST(24.61±7.58) U·L-1,respectively.Conclusion: Curcumin can protect the hepatic precancerous lesions in the mice attacked by diethylnitrosamine,and combination use of curcumin and Rhizoma Dioscoreae can be more effective.

Objective:To observe the effect of ursolic acid on hepatic precancerous lesion in mice.Methods:Except for rats in control,model rats were intraperitoneally injected with diethylnitrosamine(DEN) for inducing hepatic precancerous lesions.Ursolic acid(225.0mg/kg) or it(112.5 mg/kg) with medlar Abstraction(1 200.0mg/kg) was administrated intragastricall for treating the lesions in 10 weeks.Hepatic function was detected as ALT,AST,ALP,GST.Pathological changes were observed under microscopy and their degrees were evaluated by morphormetry.Results:Compared with those of control rats,the hepatic precancerous lesions of model rats were indicated as the hepatic dysfunction as elevated ALT,AST,ALP activities in sera,the hepatic cirrhosis as decreased hepatic indexes,collagen deposition and pseudolobule formation,and the atypia of hepatocytes as the increased nuclear volloms.The lesions in model rats were confirmed with their morphormetries.The pathological changes were relived with ursolic acid,more with the ursolic acid jointed with medlar Abstraction.Conclusion:Ursolic acid has the potency to relieve hepatic precancerous lesions.This effect was enhanced with medlar.
