Objective To explore the clinical efficacy of entecavir combined with Vitamin E in treating patients with Chronic hepatitis B complicated with non-alcoholic fatty liver.Methods Retrospective analysis was done by reviewing the clinical data of 103 patients, who suffered with chronic hepatitis B complicated with non-alcoholic fatty liver and treated in our hospital from 2015 to 2016.The patients were divided into the control group with 61 cases and the observation group with 42 cases based on different therapies.The control group was treated with only entecavir while the observation group was treated with entecavir and Vitamin E, and both the courses of treatment lasted for 6 months.The negative conversion ratio of HBV-DNA, levels of ALT, TBIL, ALP, the disease state and the adverse reactions of the two groups were compared before and after treatment.Results The negative conversion ratio of HBV-DNA of the observation group was obviously higher than that of the control group, and the patients of the observation group showed significant improvement.Meanwhile, the levels of ALT, TBIL and ALP in the two groups were both lower than before treatment.Compared with the control group, those indexes in the observation group were significantly lower (P<0.05).Conclusion Entecavir combined with Vitamin E for the treatment of chronic hepatitis B complicated with non-alcoholic fatty liver could significantly decrease the viral infections so that the state of patients can be improved.

Objective To apply the optical coherence tomography(OCT) to detect the characteristics of coronary artery plaque and to investigate its correlation with levels of serum matrix metalloproteinase 7(MMP 7),MMP9 and MMP12.Methods The patients undergoing coronary arterial angiography for diagnosing coronary arterial lesions in the cardiology department of our hospital from October 2014 to March 2016 were collected and included into the research subjects.The subjects were divided into the stable plaque group and unstable plaque group based on the results of OCT scanning.The neovascularization characteristics such as the fibrous cap thickness of plaque,angle of lipid pool,macrophage infiltration and plaque cracks were detected by using OCT.ELISA was used to measure serum MMP7,MMP9 and MMP12 levels.Results (1) The fibrous cap thickness in the stable plaque group was more than that in the unstable plaque group(P<0.01);the lipid pool angle,microphage infiltration,intima erosion and plaque cracks in the unstable plaque group were more than those in the stable plaque group(P<0.05).(2) The MMP7 and MMP9 levels in the unstable plaque group were higher than those in the stable plaque group and control group(P<0.05).(3) The fibrous cap thickness had significantly negative correlation with serum MMP9 level(r=-0.336,P=0.034);the MMP7 and MMP9 levels in the microphage infiltration group were higher than those in the non-microphage infiltration group(P<0.05);the MMP9 level in the intima erosion group was higher than that in the non-intima erosion group(P<0.01).Conclusion OCT can detect and find unstable plaque and the serum levels of MMP7 and MMP9 are significantly elevated in the patients with unstable plaque,which can be used as an important basis for predicting unstable plaque and guiding the treatment decisions.

The effect of cholesterol ester transfer protein(CETP) on SR-B1 mRNA expression in mouse liver was investigated.The results demonstrated that CETP transgenic mice showed lower serum total cholesterol and high density lipoprotein-cholesterol levels but higher total cholesterol and cholesterol ester content in liver when compared with wild type mice(P<0.05).The expression of SR-B1 mRNA in liver of CETP transgenic mice was significantly lower as compared with the control group(P<0.05).

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.

To explore an efficient strategy for the conversion of antibacterial fluoroquinolones into antitumor fluoroquinolones, an azole heterocyclic ring of oxadiazole instead of the C-3 carboxylic acid group with a functionalized hydrazone group as a modified side-chain, fifteen novel 2-(fluoroquinolon-3-yl)-oxadiazole-5- sulfanylacetylhydrazone derivatives 7a-7o were designed and synthesized on the basis of the pharmacophore hybridization principle from pefloxacin, separately. The structures for fifteen title compounds were characterized by elemental analysis, 1H NMR and MS, and their in vitro antitumor activity against Hep-3B cell line was evaluated by a MTT assay. The results showed that the title compounds exhibited more significantly inhibitory activity than that of the parent pefloxacin, in which compounds with electron-withdrawing group attached on aryl ring had more potency than that of compounds with electron donating group, especially compounds with a carboxylic substituent were comparable to comparison doxorubicin. It suggests that it is favorable for an improvement of antitumor activity to remain a carboxylic acid unit at the aromatic ring.
