Combined hepatocellular and cholangiocarcinoma (HCC-CC) is a rare primary hepatic neoplasm (PHN) with features of both hepatocellular and biliary differentiation. Hepatitis B and hepatitis C are the major causes of HCC-CC. Surgical treatment is the main therapeutic method for HCC-CC. For patients with unresectable lesions, curative or palliative locoregional therapy is applied, including radiofrequency ablation (RFA), transarterial chemoembolization (TACE) and supportive treatment. Because of the rare occurrence and ambiguous clinical features of HCC-CC, it is most often misdiagnosed with the other two types of primary liver cancer. Thus, the realization of the current progress of combined hepatocellular and cholangiocarcinoma is particularly important for us. This article aims to summarize the epidemiology and clinical futures, the treatment and prognosis, the progress of genetics and molecular analysis of HCC-CC.

This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

This article was aimed to study the antioxidant and antihyperlipidemic effect of total phenolic composition prepared from pineapple (A nanas comosus L.) leave. It had a rapid absorption after intragastric administration and the principle ingredient, p-coumaric acid, reached the peak concentration after 5 minutes of administration. The mice model with single intragastric administration of lipid and glucose were used in the observation of changes on postprandial glucose, lipid and intestinal lipase at different time points after drug administration. The results showed that phenols of pineapple leave can inhibit triglyceride and glucose absorption in certain extent. No significant effect was observed on inhibition at 30 minutes after the phenol administration. However, the intestinal lipase activity was obviously inhibited in normal mice and the intestinal lipase activity decline caused by acute lipid consumption can be reversed. It was concluded that the phenols pineapple leave may inhibit the absorption of lipids with correlation to lipase activity. It had certain regulation effect on the high postprandial glucose and fat absorption.

This article was aimed to study the general reproductive toxicity in mice in order to give a better evalua-tion of the medicinal plant of pineapple leaves (A nanas comasus L). Adult male and female mice were orally admin-istered with pineapple leaves. And then, each of the male and female mice was put together in one cage for mating. The mating success females were fed continuously. The experimental observation was conducted in pregnancy, fetal development, as well as the offspring of mice. The results showed that in addition to a large dose of pineapple leaves (4 g·kg-1) of the parental male rats having a lower body weight, pineapple leaves did not significantly affect on other parameters. There were no significant effects on pregnant mice and their offspring of mice. It was concluded that the pineapple leaves did not influence the general reproductive function of mice apparently.

Objective:To investigate whether IL-7-secreting oncolytic herpes simplex virus(HSV)could activate CD8+T cells and inhibit the growth of hepatocellular carcinoma.Methods:The expression of IL-7 was detected by Western blot.The in vitro cleavage of tumor cells by tumor oncolytic virus HSV and HSV-IL-7 were detected by crystal violet staining.The tumor inhibition ability of HSV-IL-7 and HSV were detected in subcutaneous transplanted tumor model.Levels of IL-7,IFN-γ and TNF-α in serum and tumor tissues were determined by ELISA.The infiltration of CD8+T cells in tumor tissues was detected by immunohistochemistry.Flow cytometry was used to detect Granzyme B secretion in CD8+T cells infiltrated by tumor.Results:Tumor cells infected with HSV-IL-7 expressed high level of IL-7.Both HSV and HSV-IL-7 can effectively lyse B16-F10,CT-26 and H22 tumor cell lines in a dose-dependent manner in vitro.HSV-IL-7 could significantly inhibit the growth of H22 hepatoma cells in vivo(P<0.01)and prolong the survival time of tumor-bearing mice(P<0.001).HSV-IL-7 could significantly increase the IL-7 content in tumor sites(P<0.000 1),and effectively increase the number of tumor infiltrating CD8+T cells(P<0.001).HSV-IL-7 significantly enhanced Granzyme B secretion of tumor-infiltrating CD8+T cells and IFN-γ and TNF-α in tumor tissues(P<0.000 1).Conclusion:HSV-IL-7 has well tumor inhibition activity in vivo and in vitro.It also can activate the anti-tumor activity of CD8+T cells in vivo by secreting IL-7,inhibit tumor growth and prolong the survival time of tumor-bearing mice.

Objective To investigate the regulatory role of ubiquitin-specific protease 10(USP10)on the protein expression of Krüppel-like factor 4(KLF4)and its impact on the proliferation and invasion ability of hepatocellular carcinoma(HCC)cells.Methods The protein expression differences of USP10 and KLF4 in normal liver cell line L02 and HCC cell lines,including HepG2,HUH7,HCCLM3 were detected by immunoblotting(Western blot)methods.HCCLM3 and HUH7 cells were selected,and lentiviral particles overexpressing or silencing USP10(oe-USP10 or sh-USP10)was transfected into the cells,and they were designated as the oe-USP10 group and oe-NC group,respectively.Immunoprecipitation(Co-IP)experiments were conducted to examine whether USP10 could di-rectly interact with KLF4 in HCCLM3 or HUH7 cells.The Co-IP assay was repeated in HCC cells transfected with oe-USP10 or sh-USP10,with the addition of the proteasome inhibitor MG132,which used to detect the ubiquitina-tion level of KLF4 protein in the transfected HCC cells.The pcDNA3.1 vector containing overexpressed KLF4 or its negative control plasmid(pc-KLF4 or pc-NC)was co-transfected into cells of the sh-USP10 group or sh-NC group.These cells were designated as the sh-NC+pc-NC group,sh-USP10+pc-NC group,sh-NC+pc-KLF4 group,and sh-USP10+pc-KLF4 group.The cell proliferation activity of each group was measured using the CCK-8 assay,and the cell invasion ability was assessed using the Transwell assay.Results Compared to L02 cells,the protein expres-sion of USP10 and KLF4 significantly decreased in HepG2,HUH7,HCCLM3,and other cells(P＜0.05).In HC-CLM3 and HUH7 cells,USP10 protein directly interacted with KLF4.Furthermore,treatment with MG132 resulted in a time-dependent increase in KLF4 protein expression in HCCLM3 and HUH7 cells.Silencing USP10 increased the ubiquitination of KLF4 in HCCLM3 or HUH7 cells,while overexpressing USP10 decreased the ubiquitination level of KLF4 in cells.Compared to the sh-NC+pc-NC group,both the proliferation activity and invasion ability of HCCLM3 and HUH7 cells significantly increased in the sh-USP10+pc-NC group(P＜0.01),while they signifi-cantly decreased in the sh-NC+pc-KLF4 group and sh-USP10+pc-KLF4 group(P＜0.05).Compared to the sh-USP10+pc-NC group,the proliferation activity and invasion ability of cells significantly decreased in the sh-USP10+pc-KLF4 group(P＜0.05).Conclusion USP10 can promote the stability of KLF4 protein through deubiquiti-nation in HCC cell lines,thereby inhibiting the proliferation and invasion of tumor cells.
