Subclinical infection of vaccinated chickens with a highly pathogenic avian influenza A(H5N2) virus was identified through routine surveillance in China. Investigation suggested that the virus has evolved into multiple genotypes. To better control transmission of the virus, we recommend a strengthened program of education, biosecurity, rapid diagnostics,(More)
Bovine influenza virus was first identified in the USA in 2013, and the virus represents a potential novel type of influenza viruses. However, the distribution and evolution of the virus remain unknown. We conducted a pilot survey of bovine influenza virus in China, and identified three bovine influenza viruses which are highly homogenous to the ones(More)
Multiple common avian infectious diseases (CAIDs), namely, avian infectious diseases excluding highly pathogenic avian influenza and Newcastle disease, such as avian salmonellosis and coccidiosis, cause huge economic loss in poultry production and are of great significance in public health. However, they are usually not covered in the systems for reporting(More)
The genetic diversity, evolution, distribution, and taxonomy of some coronaviruses dominant in birds other than chickens remain enigmatic. In this study we sequenced the genome of a newly identified coronavirus dominant in ducks (DdCoV), and performed a large-scale surveillance of coronaviruses in chickens and ducks using a conserved RT-PCR assay. The viral(More)
AIM To investigate the expression of IGF-IR and COX-2 in renal cell carcinoma(RCC). To explore the correlation among IGF-IR, COX-2 and PCNA expression. METHODS Immunohistochemical staining was performed to detect the expression of IGF-IR, COX-2 and PCNA in 64 cases of RCC. RESULTS The positive rates of IGF-IR expression and COX-2 expression were(More)
AIM To study the expression and clinical significance of tumor susceptibility gene 101 (TSG101) expression in hepatocellular carcinoma (HCC) tissues. METHODS The expression of TSG101 in HCC and corresponding non-tumor tissues was detected by immunohistochemistry and Western blotting. Statistical analyses were conducted to test the relationships of TSG101(More)
OBJECTIVE To evaluate the effectiveness of stroke prevention among high risk population, using Nao'an Capsules. METHODS Participants were selected from 696,558 residents in Nanhui, using county of Shanghai city. Individuals aged 35 years old and over with at least one risk factor exposure to stroke, received cerebral vascular hemodynamic examination.(More)
Recent outbreaks of a novel H7N9 avian influenza virus in humans in China raise pandemic concerns and underscore an urgent need to develop effective vaccines. Theoretically, live influenza vaccines are of multiple advantages over traditional inactivated influenza vaccines to be used in a pandemic, because they can be produced rapidly, safely, and(More)
OBJECTIVE To study the reference range of cerebrovascular hemodynamics indexes (CVHI) in a sampling population. METHODS Fourteen thousand, four hundred and eighty participants without history of stroke or exposure to risk factors were screened from 26 cities in Northeast China, North China, East China, Northwest China, South China, and Southwest China in(More)
OBJECTIVE To probe into changes of cerebral vascular hemodynamics indexes (CVHI) from normal population to different clinical stage before and after occurring of stroke. METHODS Participants were selected from 25,355 stroke cohort study population aged 35 years and over in Northeast of China and 55 acute stroke patients were selected from Fuzhou PLA(More)
