Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is one of the most frequently occurring cancers. Hepadnaviral DNA integrations are considered to be essential agents which can promote the process of the hepatocarcinogenesis. More and more researches were designed to find the relationship of the two. In this study, we investigated whether HBV DNA integration occurred at sites of DNA double-strand breaks (DSBs), one of the most detrimental DNA damage. An 18-bp I-SceI homing endonuclease recognition site was introduced into the DNA of HepG2 cell line by stable DNA transfection, then cells were incubated in patients' serum with high HBV DNA copies and at the same time, DSBs were induced by transient expression of I-SceI after transfection of an I-SceI expression vector. By using nest PCR, the viral DNA was detected at the sites of the break. It appeared that integration occurred between part of HBV x gene and the I-SceI induced breaks. The results suggested that DSBs, as the DNA damages, may serve as potential targets for hepadnaviral DNA insertion and the integrants would lead to widespread host genome changes necessarily. It provided a new site to investigate the integration.

Objective To investigate the correlation of the expression of high mobility group protein B1 (HMGB1) and blood-borne metastasis in patients with pancreatic carcinoma. Methods The serum HMGB1 levels were determined by Western blot analysis in 68 patients with pancreatic cancer, 18 patients with chronic pancreatitis and 21 healthy controls. Among the 68 patients with pancreatic cancer, the serum HMGB1 levels of 37 patients before and after operation were compared. The expression of HMGB1 and CD31 were detected by immunohistochemistry in 67 patients with pancreatic carcinoma. Results The serum HMGB1 levels in patients with pancreatic cancer was (119.7±54.5) ng/ml, which was significantly higher than (40.2±25.5) ng/ml in chronic pancreatitis (P<0.001) and (13.1±4.3) ng/ml in healthy control (P< 0.001). The serum HMGB1 levels in patients with pancreatic cancer before operation was (120.2±8.2) ng/ml, which was significantly higher than (69.3±5.1) ng/ml after operation (P <0.001). The expression rate of HMGB1 in pancreatic cancer tissues was 43.6%. The expression of HMGB1 were significantly related with tumor differentiation, TNM stage, blood-borne metastasis, and vascular density(P <0.01). The HMGB1 positive tumor cells were adjacent to the blood vessels with lumen, and the rate of HMGB1 expression in intravascular tumor cells was 71%. Conclusions The HMGB1 was highly expressed in pancreatic cancer tissues. HMGB1 expression positive pancreatic carcinoma cells were prone to invade blood vessels with lumen which may be related to blood-borne metastasis in pancreatic cancer.

Objective:To evaluate the immunological efficacy of a novel DNA vaccine against West Nile virus (WNV) in a mouse model.Methods:A DNA vaccine VRC-prME expressing the precursor membrane (prM) and envelope protein (E) of WNV Xinjiang strain (XJ11129-3) was constructed and its ability to express virus-like particles was verified in vitro. C57BL/6 mice were immunized twice with VRC-prME via intramuscular injection combined with electroporation with an interval of four weeks. Enzyme-linked immunoassay (ELISA) was used to detect serum antibodies after immunization. WNV (NY99 strain) single-round infectious particles were used to detect neutralizing antibodies. Cellular immune responses were analyzed by enzyme-linked immunoblot assay (ELISPOT) and intracellular cytokine staining (ICS). Results:VRC-prME induced a strong Th1-biased antibody response in mice that could cross-neutralize the WNV (NY99 strain) single-round infectious particles two weeks after the boost immunization. Moreover, the vaccine also elicited antigen-specific multifunctional CD8 + T cell responses (IFN-γ, IL-2, TNF-α). Conclusions:The novel DNA vaccine prepared in this study, expressing the prME protein of WNV XJ11129-3 strain, could induce stronger humoral and cellular immune responses in mice, which was worthy of further research and development for the prevention of WNV infection in China.

A unique one-step ethanol fermentation process was developed with the inulinase-producing strain Kluyveromyces marxianus YX01. Firstly, the impact of temperature on ethanol fermentation was investigated through flask fermentation, and the temperature of 35 degrees C was observed to be the optimum to coordinate inulinase production, inulin saccharification and ethanol fermentation. And then, the impact of aeration and substrate concentration was studied through batch fermentation in the 2.5 L fermentor, and the experimental data indicated that the average ethanol fermentation time was decreased at the aeration rates of 50 mL/min and 100 mL/min, but higher ethanol yield was obtained under non-aeration conditions with more substrate directed to ethanol production. The ethanol concentration of 92.2 g/L was achieved with the substrate containing 235 g/L inulin, and the ethanol yield was calculated to be 0.436, equivalent to 85.5% of its theoretical value. Finally, Jerusalem artichoke grown in salina and irrigated with seawater was fermented without sterilization treatment, 84.0 g/L ethanol was obtained with the substrate containing 280 g/L dry Jerusalem artichoke meal, and the ethanol yield was calculated to be 0.405, indicating the Jerusalem artichoke could be an alternative feedstock for grain-based fuel ethanol production.

Objectives:To observe the changes of the tongues in rats with blood-stasis syndrome induced mainly by cold. To explore the evidence that tongues were the target of blood stasis syndrome and the target of medication. Methods: Rats with blood-stasis syndrome induced by cold (BSC group) were dipped into ice water (0 ℃) for 5 minutes every day and lasted 20d individually. Different drugs were given orally after the model establishment. And then we took photos of tongues of all rats by digital camera, analyzed the gray scale value of all rats' tongues using image analysis software, and observed the capillaries in tongues by electron microscope. Results: The tongues of rats which had been frozen in ice water for 20 d (once a day) were dark purple, the same as that of models induced by chemical materials .While as for the normal rats, the tongues were lustrous and ruddy. The changes of color of the tongues persisted about 1 week and were great obvious at the 3rd day after the model establishment among different time-points. After given different drugs, the degree of dark purple tongue degraded, showed significant difference (P < 0.01) from that of model rats. The capillary stegnosis and nucleus turgescence of vascular endothelial cell were observed in tongues in BSC group by using electron microscope. After medication, the above changes recovered. Conclusion: The degree of dark purple tongue indicates the degree of diseases with blood-stasis syndrome. The tongue probably is a target of drug treatment.

Objective Acute coronary syndrome ( ACS) is frequently accompanied by chronic comorbidities , which may se-riously affect its prognosis .This study aims to investigate the value of the Charlson Comorbidity Index ( CCI) in predicting the outcome of ACS by assessing the impact of individual and post-weighted-assignment comorbid conditions of the disease . Methods We retro-spectively analyzed the clinical data on 1 096 cases of ACS treated in Jinling Hospital from January 2010 to March 2014 .We reviewed their general information , clinical presentations , complications , and previous treatments , calculated CCI , and used in-hospital mortali-ty as the index for judging the prognosis . Results Of the 1 096 patients, 73%were males (aged 64.2 ±12.9 years), 27% were females (aged 72.1 ±12.6 years), and 46.8% had comorbidities. Of the diseases included in the CCI system , previous myocardial infarction was the most frequent comorbidity (18.0%), followed by diabetes mellitus ( 14.7%), moderately to severe renal disease (7.1%), cerebrovascular disease (6.0%), and chronic lung dis-ease (6.0%).Single factor analysis revealed statistically significant differences between different CCI groups in such clinical indicators as history of coronary artery disease , history of hypertension , time between symptom onset and admission , hemodynamics , drugs adminis-tered (aspirin, P2Y12 blockers, ACEI/ARB or statins), and reperfusion therapy (P<0.05).Logistic regression analysis showed the strongest predictors of in-hospital mortality were heart failure (OR 1.88, 95%CI:1.57-2.25), metastatic tumor (OR 2.25, 95%CI:1.60-3.19), renal disease (OR 1.84, 95% CI:1.60-2.11), and diabetes mellitus (OR 1.35, 95% CI:1.19-1.19). Receiver operating characteristic curve analysis manifested that either CCI with age or CCI with age and gender was superior to CCI a -lone in predicting in-hospital mortality of ACS patients (AUC 0.761 [95%CI 0.748-0.773] and 0.756 [95%CI:0.743-0.768] vs 0.670 [95%CI:0.656-0.685]). Conclusion Heart failure, diabetes mellitus, renal disease, and metastatic tumors contrib-ute to the in-hospital mortality of ACS patients .CCI together with age and gender may help to assess the prognosis of the disease .
