The outbreaks of Zika virus infection in different regions of the world underscore the potential for the virus to spread further in the Americas and beyond.Zika is a mosquito-borneFlavivirusand is transmitted by Aedes spp. mosquitoes.It is has been reported recently that Zika virus intrauterine infection causes fetal brain abnormality and microcephaly, and WHO encourages pregnant women in countries at risk MUST protecting themselves from mosquito bites. Until now, there is no imported case in China.We have established resource and technology storage to reply to the potentialZika cases in the future, therefore, people do not need to panic in China.

Animal model plays an important role in prevention and control of infectious disease, which could link basic research in laboratory with clinical diagnosis and treatment for human patients.Mouse is the most widely used animal model of infectious disease, however, adult immunocompetent mice are resistant to some pathogens.The highly genetically diverse Collaborative Cross (CC) mice could recapitulate many of the genetic characteristics of an outbred population, such as humans.Based on this, this review will focus on the application and research progress of CC mice in infectious disease (including viruses, bacteria, fungi etc.), which could provide useful reference data for expansion of animal model resource bank, and implement of precision medicine of major and new emerging infectious diseases.We hope this review could serve as a modest spur to induce other researchers to come forward with their valuable contributions.

All of them were treated with the displacement of ventricular bands-epiglottis mucosal flap in the surgical management of glot-tis carcinoma. The tumour was primarily from vocal cords, and not exceeded 2cm. Result: All cases were success-fully renovated laryngeal cavity with the displacement of ventricular bands-epiglottis mucosal flap and followed up for 5 years after operation. Three years survival rate was 86.2% ,5 years survival rate was 78.9% ,and tube draw-ing rate was 100%. Conclusion: With this method, surgery would be simplified and the patients would keep the voiced function and swallowing function.

One-hundred and eighty-eight cases of metabolic syndrome conforming to the criteria of International Diabetes Federation(IDF) were enrolled,and 166 healthy subjects served as control.Phalangeal bone mineral densities in both groups were measured.Osteocacin,bone alkaline phosphatase,and parathyroid hormone were determined with Enzyme-linked immunosorbent assay.Results:Body mass index,waist circumference,waist-tohip ratio,fasting blood glucose,blood pressure,triglycerides,total cholesterol,and low-density lipoproteincholesterol in the group with metabolic syndrome were higher than those in normal control group(all P＜0.01),while high-dcnsity lipoprotein-cholesterol was lower (P ＜ 0.01).T values,Z values,and osteocacin in the metabolic syndrome group were lower than those in control group (all P＜0.05),while parathyroid hormone was higher (P＜0.05).There was no significant difference in levels of bone alkaline phosphatase between the two groups.Metabolic syndrome as an aggregate of multiple metabolic disorders was prone to be accompanied with osteoporosis.Body mass index was an important protective factor of osteoporosis,triglycerides and waist-hip ratio were independent risk factors.

Purpose Liver fibrosis is the common pathological process of cirrhosis developed by chronic liver disease.This study aims to explore the application of microvascular change in assessing the liver fibrosis induced by bile duct ligation based on X-ray phasecontrast computed tomography (PCCT).Materials and Methods Ten rats were equally divided into the group of bile duct ligation-induced liver fibrosis and the control group at random.Then ten excised liver tissues were imaged at beamline BL13W1 of Shanghai Synchrotron Radiation Facility in China.After the imaging studies,the liver samples were stained with Sirius red and immunostained with antibodies against cytokeratin 19 (CK19).The microvasculature in livers was reconstructed via PCCT,and the correlation analysis on microvascular density and the proportion of fibrosis area was performed.Results The microvasculature including blood vessels,dilated bile ducts and ductular proliferation were clearly revealed by PCCT technology.Moreover,the 3D microvascular density and proportion of fibrosis area in the liver fibrosis group increased significantly compared with those in the control group (P＜0.01),and the correlation between them was obvious (r=0.812,P＜0.01).Conclusion Microvascular 3D characteristics of liver fibrosis are well demonstrated by PCCT,and 3D microvascular density is significantly correlated with the proportion of fibrosis area.Those findings indicate that microvascular change is closely related to the degree of liver fibrosis induced by bile duct ligation,and thus it provides a novel means to assess the severity of liver fibrosis through microvascular change.

Objective To compare the radiosensitivity effect of celecoxib on oln93 and u373 cells,and to explore the related mechanism.Methods Both oln93 cells and u373 cells were respectively divided into control group,drug group,radiation group and combined group when treated with celecoxib and irradiation.Cell survival ratio was evaluated by MTT assay and clogenic assay.Flow cytometry and Western blot assay were used to measure cell cycle and protein expression.Results Celecoxib had a similar effect on oln93 and u373 cells in enhancing the radiosensitivity (t =2.215-30.996,P ＜ 0.05 ; t =0.383-11.732,P＜0.05)and blocking cellcycle in G0/G1(t=-6.1-5.141,P＜0.05).Compared with the radiation group,the combined group showed S phase arrest(t =-18.174,P ＜ 0.05),and increase of Cyclin A protein (t =-8.087,P ＜ 0.05) in oln93 cells,and G2/M arrest and decrease of Cyclin B1 and DNA-PKcs and MRE11 protein (t =-8.838-10.45,P ＜ 0.05) in u373 cells.Conclusions Celecoxib illustrates a more sensitive radiosensitivity to u373 cells by regulating its cell cycle and DNA damage repair.

ABSTRACT:Objective To investigate the interaction of polymorphisms of TNF-αgene promoter-308G/A and PPAR-γ2 gene-C34G with acute pancreatitis (AP)and its severity degree.Methods Totally 150 mild acute pancreatitis(MAP),150 moderately severe acute pancreatitis(MSAP)and 150 severe acute pancreatitis(SAP)cases were selected for this study,and 450 healthy persons as control group.The genetic polymorphisms of TNF-αgene promoter-308G/A and PPAR-γ2 gene-C34G were analyzed by the technique of PCR in peripheral blood leukocytes of above-mentioned cases and the results were verified by direct DNA sequencing method.Results The frequencies of -308G/A(GA),-308G/A(AA),-C34G(CG)and-C34G(GG)were 24.00%,26.67%,24.00% and 26.00% in MAP group,34.67%,36.67%,34.00% and 36.67% in MSAP group,42.00%,46.00%,43.33% and 46.00% in SAP group,and 14.44%,14.22%,12.89% and 14.67% in control group,respectively.Statistical tests showed significant difference in the frequencies among each group (all P<0 .0 1 ).The risk of AP significantly increased in subjects with-308G/A(GA),genotype (ORMAP=2.677 6,ORMSAP=6.625 0,ORSAP=21.514 7),in those with-308G/A(AA)genotype (ORMAP=2.570 0,ORMSAP=6.401 8,ORSAP=18.903 4),in those with-C34G(CG) genotype (ORMAP=2.668 4,ORMSAP=6.776 9,ORSAP=22.207 2),and in those with-C34G(GG)genotype (ORMAP=2.633 8,ORMSAP=6.472 5,ORSAP=21.570 2).Combined analysis of the polymorphisms showed that percentage of-308G/A(AA)/-C34G(GG)in MAP,MSAP,SAP and control groups was 7.33%,13.33%,20.67% and 2.00%,respectively,and statistical tests showed significant difference in the frequency among each group (all P<0.01).The people who carried-308G/A(AA)/-C34G(GG)had a high risk of AP (ORMAP=7.284 2,ORMSAP=41.296 1,ORSAP=363.973 6),and statistical analysis suggested a positive interaction between-308G/A(AA)and-C34G(GG)in increasing the risk of AP (γ2MAP=2.114 2,γ4MAP=2.080 0,γ2MSAP=2.108 7,γ4MSAP=2.050 6,γ2SAP=2.138 8,γ4SAP=2.000 1).Likewise,there were also positive interactions in the pathogenesis of AP between-308G/A(GA)and-C34G(GG),-308G/A(GA)and-C34G(CG),-308G/A(AA)and-C34G(CG)(All γ>1). Conclusion These carriers of-308G/A(GA),-308G/A(AA),-C34G(CG)and-C34G(GG)genotypes may have a high risk of developing AP,and significant interactions between genetic polymorphisms of-308G/A and-C34G add the risk of the occurrence and development of AP.

To set up a new rapid method for the rapid determination of influenza virus H5N1 and H7N9 basing on the Multi-Analyte Suspension Array (MASA) technology. Sequence analysis and design of degenerate primers and specific probes were set in the comparison and analysis of H5, N1, H7 and N9 genes. In combination with MASA technology, these primers and probes were used for the determination of samples of H5N1 and H7N9 and other subtypes ( H1N1, PH1N1, H5N2, H3N2 and H9N2). We developed a rapid determination method. This method had high specificity and sensitivity that could detect H5N1 and H7N9 at one time, and could detect samples that containing 10 copies of H5N1 and H7N9. This determination method could be used for rapid determination of influenza virus H5N1 and H7N9 at one time.
