On August 8, 2014, the World Health Organization(WHO) declared the cross-country Ebola outbreak a Public Emergency of International Concern. China has had no confirmed cases of Ebola. In this paper, virologic characteristics, pathogenesis, clinical manifestations, laboratory examination and prophylactic vaccines and therapeutic drugs of Ebola are summarized. Importantly, active responses and actions from China are introduced. Moreover, the key issues in the future prevention and control of Ebola were also addressed.展开更多

The objective of this study was to investigate the association of the expression of CAS protein with HBV infection in the development of HCC. Methods The expression level of CAS was measured with immunohistochemistry. The occurrence of HBs Ag, HBe Ag and HBV DNA in HCC were concurrently examined with immunohistochemistry and in situ hybridization, respectively. Results The results showed that the CAS protein was detected in 86%(43/50), 70%(7/10), 15%(3/20) and none(0/20) of livers from patients with HCC, cholangiocarcinoma, cirrhosis and hepatitis, respectively. Furthermore, the level of CAS protein was higher in poorly differentiated tumors than moderately or well differentiated HCC. Interestingly, the CAS was stained significantly stronger in HBV-infected HCC than in non-HBV infected tissues(P < 0.01). Conclusions The expression of CAS is facilitated by HBV infection in HCC, suggesting that CAS might be a prognostic marker and a putative therapeutic target for HCC.展开更多
