Objective To identify the pathogen that caused the cluster of HFMD epidemic in a middle school of Fuxin City in September 2019, and to find out the homogeneity of the pathogen. Methods The samples were preliminary identified by real-time PCR. Partial VP1 sequences were amplified by nested PCR. The virus type was identified by sequencing and blast comparison. and the homology and phylogenetic analyes of VP1 region were performed by bioinformatics software with CV-A6 reference sequences. Results S...

Objective To evaluate the antiviral effects of the Qingkailing injection against Dengue virus type 1 (DENV- 1) in vitro. Methods The maximum non-toxic dose and anti-DENV-1 effect of Qingkailing injection on the C6/36 cells was determined by MTT. The effect of Qingkailing injection on DENV-1 was determined by MTT. Using NS1 protein as the target protein, the infectivity of DENV-1 pretreated with different dilution of Qingkailing injection was detected by Western Blot. The effect of Qingkailing in...
