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.

Objective:To investigate the plastic method of glottis carcinoma in surgery. Method:Retrospectly analyzed 29 patients with T_2 ,T_3 glottis carcinoma who admited in our department From 1996 to 2004. 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.

Objective To discuss the nursing resources allocation status in Xinjiang production and construction corps so that reasonable allocation,utilization and management of the nursing work-forces can be strengthened for ensuring the nursing qualities and adapting to the needs of continuous development of the profession.Methods Information such as the quantity,age,education and the title of technical post of tbe nurses in the year of 2005 was collected and analyzed.Results The results showed shortage of nurses,the average doctor-nurse ratio was 1:1.20;the age structure of the objects investigated was suitable,small at beth ends and big in the middle.while more well educated and well technical post titled nurses were needed.Conclusions The quantity of nurses should be increased properly and the present nursing labors should be made use of scientifically,what's more,the training of the bilingual skill of the nurses should be given according to the multinational region features.

Objective To investigate the natural infection status of murine norovirus ( MNV) in laboratory mice in Shanghai area and isolate MNV from mouse cecal feces .Methods To collect cecal contents and serum samples from 319 specific pathogen-free ( SPF) mice coming from different research institutions .Reverse transcription-polymerase chain reaction ( RT-PCR) and enzyme linked immunosorbent assay ( ELISA) were used to detect MNV infection in the mice , re-spectively.The positive stool samples were diluted and filtered through 0.22 μm membrane, inoculated into RAW 264.7 cells, and then identified by RT-PCR.Results There were 95 positive results in the 319 cecal samples by RT-PCR, and the positive rate was 29.78%.Among 180 serum samples which were tested by RT-PCR, 70 samples were positive by ELISA, and the positive rate was 38.89%.The infected RAW 264.7 cells showed cytopathic effect ( CPE) within 72 h. After 3 times of freezing and thawing , RT-PCR obtained a 187 bp band.Conclusions The results from the present study show that there is a high natural infection rate of MNV in laboratory mice in Shanghai area , and the strict breeding manage-ment must be strengthened .

Objective In order to construct the standards of review for oncology nursing professional training base by aggregating the requirement of the professional training base in multiple regions in China.Methods Delphi expert consultation method by self-designed questionnaire were conducted among 21 nursing educators in medical university,nursing administrators,oncology clinicians,oncology clinical nurse specialists in hospitals.Results The Cr,Cronbach's α was 0.825,0.980.A standards of review for oncology nursing professional training base included 5 first-level indicators,19 second-level indicators and 76 third-level indicators after three rounds of consultation.Conclusions The 100-item for standards of the review is reliable and valid,which can provide objective and quantitative standards for evaluation,assessment and access of oncology nursing professional training base.

Objective To investigate the prevalences of the nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome( MS), and analyze the relationship between the two kinds of diseases in retired old people in Wuhan. Methods Seven hundred and eighteen retired old people (≥60 years old) were surveyed. The height, body mass index, waist circumference, blood pressure, blood glucose, blood lipid and liver B uhrasonography were examined. Results The prevalences of MS and NAFLD were 25.2% and 25.9% respectively, and the prevalences of hypertension, hyperglycemia, hypertriglyceridemia, low high-density lipoprotein cholesterol and abdominal obesity were 89.2%, 29.6%, 40.3%, 10.3% and 38.6% respectively. The prevalence of MS was higher in women than in men (χ2=21.0, P<0.05). The risk of NAFLD was increased with the increase of MS components numbers (male: χ2=82.9;female: χ2=23.7, both P<0.01). There was a positive correlation between the prevalence of NAFLD and MS in the elderly (male: OR=2.216;female: OR =4.848,both P<0.01). Conclusions The prevalences of NAFLD and MS are high in retired old people in Wuhan, and there is significant relationship between the two kinds of diseases. Great attention should be paid to the two risk factors for cardiovascular diseases in the elderly.

Neuregulin-1,a member of the epidermal growth factor family,plays an important role in the neuronal survival,development,migration,myelin formation,and synaptic plasticity and function. This article mainly summarized the structure and function of neuregulin1 and its neuroprotective roles in cerebral ischemia. Tne neuroprotective mechanisms of neuregulin-1 may include the inhibition of the early inflammatory response and apoptosis,and the regulation of the expression the neurotrophic factors.

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.
