In addition , patients are tolerant.

Objective To observe the prevention and treatment of the total flavonoids from Litchi chinensis Sonn( TFL) on hepatic fibrosis induced by dimethylnitrosamine(DMN)in rats, and to explore its mechanism. Methods Ninety SD rats were randomly divided into six groups, normal control group, model control group, colchicine group, high-, medium- and low-dose TFL group(n=15).Expect for normal control group, the other groups were given intraperitoneal injection of 2 mL.kg-1 of 5% dimethylnitrosamine for 4 weeks as the model group. The rats in the normal control group and model control group were given 5 mL.kg-1of 0.9% sodium chloride solution, colchicine group was treated with 0.1 mg.kg-1 colchicine.High-, medium-and low-dose TFL groups were given 200, 100 and 50 mg.kg-1 of TFL.The rats were sacrificed and the livers were harvested and stained with HE and Masson staining to observe pathological changes and liver fibrosis in the same part 6 weeks after all the medicine was given to the rats each day. Immunohistochemistry and Western blotting were used to detect the expression of the transforming growth factor β-Ⅰ/type Ⅱ receptor ( TβRⅠ/Ⅱ) , collagen Ⅰ( Col Ⅰ) and Ⅲ collagen ( Col Ⅲ) . Results Compared with the normal control group, the semiquantitative score of liver fiber and the protein expression of TβRⅠ, TβRⅡ, ColⅠ and Col Ⅲ in the model control group were significantly increased(P<0.01).Compared with the model control group, the protein expression levels of TβR, TβRⅡ, ColⅠand ColⅢwere significantly decreased( P<0.01) in the high-,medium-and low-dose TFL group.The semiquantitative score of liver fiber was significantly decreased( P<0.01) with a dose-effect relationship. Conclusion TFL can inhibit formation of DMN-induced liver fibrosis in rats, which may be related with reduction of expression of TβRⅠ/Ⅱ of hepatic fibrosis promoting factor TGF-β1 , inhibition of the activation and increase of hepatic stellate cells, reduction of the collagen content.

Objective To investigate effects of total flavonoids of litchi (TFL) on the proliferation of rat hepatic stellate cells (HSC-T6) in comparison with western medicine rosiglitazone, and to explore the mechanism of anti hepatic fibrosis of TFL. Methods Effect of TFL on proliferation of HSC-T6 was examined by MTT. The expression of peroxisome proliferator-activated receptor-γ (PPAR-γ) mRNA, connective tissue growth factor (CTGF) mRNA in HSC-T6 cells exposured were examined by real-time quantitative PCR. Effects on HSC-T6 CTGF protein from TFL and rosiglitazone were detected by Western bloting. Results The expression of PPAR-γ mRNA was upregulated and the expression of CTGF mRNA and protein was downregulated after exposure to TFL and rosiglitazone for 72 hours. And the effect of TFL increased with the increase of concentration. Conclusion TFL can inhibit the proliferation of HSC-T6 and antagonizing liver fibrosis. This mechanism may be associated with the upregulation of PPAR-γ expression and the downregulation of CTGF expression.

ObjectiveTo study the effect of total flavone of Litchi Semen （TFL） on proliferation， apoptosis， migration， and invasion of hepatoma cells HepG2. MethodMethyl thiazolyl tetrazolium colorimetric （MTT） assay was used to detect the effect of different-dose TFL and cisplatin on the proliferation of HepG2 cells. TdT-mediated dUTP nick-end labeling （TUNEL） assay was used to detect the effects of low， medium， and high-dose （70， 140， 210 mg·L^-1） of TFL and cisplatin （60 mg·L^-1） on the apoptosis of HepG2 cells， thus selecting the optimal dose of TFL for the follow-up experiment. HepG2 cells were divided into a blank group， a TFL group （140 mg·L^-1）， a TFL+XL019 group （140 mg·L^-1 TFL+0.5 μmol·L^-1 XL019）， and a TFL+TPI-1 group （140 mg·L^-1 TFL+1 μmol·L^-1 TPI-1）. The effect of TFL on migration and invasion of HepG2 cells were examined by wound healing test and Transwell invasion assay， and the effect of TFL on the expression of epithelial-mesenchymal transition （EMT） marker in HepG2 cells were examined by cell immunofluorescence assay. Western blot was used to detect the expression of key proteins in Janus kinase 2（JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway after the intervention by TFL. ResultMTT assay showed that the proliferation of HepG2 cells was significantly inhibited by TFL and cisplatin at 24 and 48 h as compared with blank group （P<0.01）， and the half maximal inhibitory concentration （IC₅₀） of TFL on HepG2 cells was （136.7±2.40） mg·L^-1 at 24 h and （106.8±1.11） mg·L^-1 at 48 h. The IC₅₀ of cisplatin on HepG2 cells was （58.48±2.04） mg·L^-1 at 24 h and （5.15±0.56） mg·L^-1 at 48 h. The results of TUNEL assay showed that TFL induced apoptosis of HepG2 cells. The optimal dose of TFL was 140 mg·L^-1. The results of wound healing test showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the migration of HepG2 cells （P<0.05， P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 Group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The Transwell invasion assay showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the invasion of HepG2 cells （P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The results of immunofluorescence showed the intervention of TFL up-regulated the expression of E-cadherin， and down-regulated the expression of Vimentin in HepG2 cells， which was stronger in the TFL+XL019 group and weaker in the TFL+TPI-1 group. The results of Western blot showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group did not affect the expression of JAK2 or STAT3 protein， but significantly decreased the expression levels of phosphorylatied （p）-JAK2 and p-STAT3 （P<0.05， P<0.01）. As compared with the TFL group， the expression levels of p-JAK2 and p-STAT3 in the TFL+XL019 group were significantly decreased （P<0.01）， while those in the TFL+TPI-1 group were significantly increased （P<0.01）. Compared with the blank group， the TFL group significantly increased the expression level of Src-homology domain 2 containing protein tyrosine phosphatase-1（SHP-1） with sh2 domain （P<0.01）. ConclusionTFL has the effects of inhibiting the proliferation， promoting apoptosis of HepG2 cells， and reversing the EMT process of HepG2 cells to reduce the migration and invasion， which are presumably related to the activation of SHP-1 by TFL to block JAK/STAT3 signaling pathway.

Gastric cancer is a common malignant tumor of the gastrointestinal tract， with the pathogenesis remains to be fully elucidated. Although surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy have demonstrated obvious clinical efficacy in the treatment of gastric cancer， the patients suffer from complications and adverse effects. Basic experiments and clinical studies have proved that Chinese medicine can treat gastric cancer in a multi-component and multi-target manner， the mechanisms of which remain to be deciphered. Therefore， the mechanism of Chinese medicine against gastric cancer needs to be unveiled by network pharmacology and tools of molecular biology. According to Chinese medicine， the occurrence of gastric cancer is mainly attributed to liver Qi stagnation， phlegm stasis and Qi stagnation， body fluid deficiency and heat accumulation， deficiency of healthy Qi， and cancer toxin accumulation. According to the available literature， herbal compound formulas such as Sancao Tiaowei decoction， Xiaojianzhong decoction， and Yiqi Huayu Jiedu decoction focus on tonifying， clearing heat， and detoxifying， while herbal active components are mainly insecticidal， heat-clearing， blood-activating， stasis-removing， and Qi-regulating drugs. The therapeutic effects of these Chinese medicines are consistent with the etiology and pathogenesis of gastric cancer. It has been demonstrated that Chinese medicines play a role in promoting apoptosis and autophagy， blocking cell cycle， and reversing cellular drug resistance to treat gastric cancer by regulating phosphatidylinositol-3 kinase/protein kinase B （PI3K/Akt）， mitogen-activated protein kinase （MAPK）， nuclear factor-kappa B （NF-κB）， transforming growth factor-β （TGF-β）/Smad， Wnt/β-catenin， and Hedgehog signaling pathways， while there is a lack of systematic understanding. By systematically summarizing the signaling pathways related to the regulation of gastric cancer by Chinese medicine， this study aims to clarify the molecular mechanisms of Chinese medicine against the development， invasion， and metastasis of gastric cancer， with a view to providing new targets， perspectives， and ideas for the treatment of gastric cancer and promoting the modernization of traditional Chinese medicine.
