Objective To investigate the regulatory effect of Jianpi Huayu Prescription(Ginseng Radix et Rhizoma,Poria,Atractylodis Macrocephalae Rhizoma,Salviae Miltiorrhizae Radix et Rhizoma,etc.)on epithelial-mesenchymal transition(EMT)and angiogenesis of hepatocellular carcinoma through TGF-β1/Smad7 pathway.Methods(1)Hep3B tumor-bearing mouse model was established by BALB/C-nu nude mice.The mice were randomly divided into control group and Jianpi Huayu Prescription low-,medium-and high-dose groups(3.844,7.689,15.378 g·kg-1·d-1),with five mice in each group.Intragastric administration was performed once a day for 21 days.(2)Hep3B cells were divided into blank group,model group(10 ng·mL-1 TGF-β1),low-concentration group(10 ng·mL-1 TGF-β1+4 mg·mL-1 Jianpi Huayu Prescription),and high-concentration group(10 ng·mL-1 TGF-β1+6 mg·mL-1 Jianpi Huayu Prescription).After 48 hours of TGF-β1 induction,the cells were replaced with the corresponding concentration of Jianpi Huayu Prescription complete culture medium(0,4,6 mg·mL-1)and cultured for 24 hours.(3)HUVEC cells were divided into normal group,model group,Chinese medicine group,model plus Chinese medicine group.The cells in the normal group were cultured with conditioned medium without TGF-β1;the cells in the model group were cultured with conditioned medium containing TGF-β1.The cells in the Chinese medicine group were cultured in conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription without TGF-β 1.The cells in the model plus Chinese medicine group were cultured with conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription and TGF-β1.After 24 hours of continuous culture,the cells were collected for subsequent experiments.(4)The tumor mass index and tumor inhibition rate of subcutaneous transplantation tumor of Hep3B tumor-bearing nude mice were calculated.The expression of CD31 in subcutaneous xenografts of tumor-bearing nude mice was detected by immunofluorescence.The microvessel density of subcutaneous transplanted tumor in nude mice was detected by immunohistochemistry.The migration ability of Hep3B cells was detected by cell scratch test.Transwell assay was used to detect the invasion ability of Hep3B/HUVEC cells.The tube formation ability of HUVEC cells was detected.The expression levels of related proteins in subcutaneous transplanted tumors,Hep3B and HUVEC cells of tumor-bearing nude mice were detected by Western Blot.Results(1)Compared with the control group,the weight and tumor mass index of subcutaneous transplanted tumor in nude mice in the medium-and high-dose groups of Jianpi Huayu Prescription were significantly decreased(P＜0.01).The expression of CD31 and microvessel density in subcutaneous transplanted tumors of nude mice in low-,medium-and high-dose groups were significantly decreased(P＜0.05,P＜0.01),the protein expressions of VE-cadherin,EphA2 and N-cadherin were significantly down-regulated(P＜0.05,P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly up-regulated(P＜0.01).(2)Compared with the blank group,the relative migration rate of Hep3B cells in the model group was significantly increased(P＜0.05),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of Vimentin and N-cadherin were significantly up-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the relative migration rate of Hep3B cells in the low-and high-concentration groups of Jianpi Huayu Prescription was significantly decreased(P＜0.01),and the number of invasive cells was significantly decreased(P＜0.01).The protein expressions of Vimentin and N-cadherin was significantly down-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 were significantly up-regulated(P＜0.01).(3)Compared with the normal group,the number of tubular branching points formed by HUVEC cells in the model group was significantly increased(P＜0.01),the length of tubular branching was significantly increased(P＜0.01),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly up-regulated(P＜0.01),and the protein expression of Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the number of tubular branching points formed by HUVEC cells in the model plus Chinese medicine group was significantly reduced(P＜0.01),the length of tubular branching was significantly shortened(P＜0.01),and the number of invasive cells was significantly reduced(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly down-regulated(P＜0.01),and the protein expression of Smad7 was significantly up-regulated(P＜0.01).Conclusion Jianpi Huayu Prescription can significantly inhibit the growth,invasion and migration of hepatocellular carcinoma,which may be related to the regulation of EMT and angiogenesis mediated by TGF-β1/Smad7 pathway.

OBJECTIVE To explore the mechanism of Shenqi guben formula （SQGB） in improving cancer-related fatigue （CRF） based on network pharmacology and cellular experiments. METHODS Active components of SQGB and CRF-related targets were identified on the basis of databases such as the Traditional Chinese Medicine Systems Pharmacology platform. An in vitro CRF cell model was established by inducing A549 cells with interleukin-17 （IL-17）. Cells were treated with low （1.0 mg/mL） or high （1.5 mg/mL） concentrations of SQGB. The effects on cell viability， migration， apoptosis， inflammatory factors， mRNA expression， apoptosis-related proteins and key proteins 011） of IL-17 signaling pathway were evaluated using scratch assay， flow cytometry， ELISA， real-time fluorescent quantitative PCR and Western blot analysis. RESULTS SQGB contained 84 active components acting on 209 potential CRF targets. Among E-these， quercetin， kaempferol， and luteolin were identified as the core components of the compound. Core targets included tumor protein p53， AKT serine/threonine kinase 1， IL-6， and tumor necrosis factor （TNF）. IL-17， TNF and phosphatidylinositol-3- kinase-serine/threonine protein kinase （PI3K/Akt） signaling pathways were identified as crucial pathways. Compared with IL-17 intervention group， the cell migration rate， B-cell lymphoma 2 （Bcl-2） protein expression， the levels of IL-6 and TNF-α in the supernatant， mRNA expression of IL-17 receptor A （IL-17RA）， TNF-α， and IL-6， as well as the protein expression of IL-17RA and nuclear factor kappa-B p65 subunit （p65）， and phosphorylated （p）-p65/p65 ratio in IL-17+SQGB low- and high- quality concentration groups were all significantly decreased or down-regulation （P＜0.05）； the apoptosis rate， expression levels of Bcl-2 associated X protein （Bax） and cleaved caspase-3 protein， the ratio of Bax/Bcl-2， the expression level of p-p38 protein， and the p- p38/p38 ratio were all significantly increased or up-regulated （P＜0.05）. Moreover， the improvement effects of these indicators were mostly better in the high-quality concentration groups compared to the low-quality concentration groups （P＜0.05）. CONCLUSIONS SQGB ameliorates CRF by regulating the IL-17 signaling pathway， inhibiting the expression of inflammatory factors， and activating p38 MAPK-dependent apoptosis pathway.
