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.

OBJECTIVETo observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis.

METHODSixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1.

RESULTAfter 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05).

CONCLUSIONDetoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn has good effect of anti-atherosclerosis and promoting plaque stability. Its mechanism might be related with anti-inflammation and inhibiting degradation of extracellular matrix, and deserves further studies.

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.

Objective To analyze the complications due to CT-guided transthoracic aspiration biopsy for pulmonary lesions and discuss the role of puncture skill for reducing the complications.Methods CT- guided transthoracic aspiration biopsy was performed in 116 patients with intrapulmonary parenchymal occupied lesions from June 2006 to June 2007 in our hospital.The complications and the whole process of puncture were analyzed to obtain the experience for reducing the occurrence of complications.Results CT-guided transthoracic aspiration biopsy was succeeded in all 116 cases.The major complications included pneumothorax (15.51%),puncture tract hemorrhage(10.34%),hemoptysis(4.31%)and others(1.72%).Only 1 case of pneumothorax was treated by closed thoracic drainage and no specific treatment for others.Conclusion CT- guided transthoracic aspiration biopsy for pulmonary lesions is an efficient and safe diagnostic modality.The criteria for reducing the complications are associated with accurate localization,the correct breath training and evaluation of lesion before the operation.(J Intervent Radiol,2007,16:847-849)
