The genome of CK/CH/SD09/005, an isolate of infectious bronchitis virus (IBV), was characterized to enable the further understanding of the epidemiology and evolution of IBV in China. Twenty-five pairs of primers were designed to amplify the full-length genome of CK/CH/SD09/005. The nucleotide sequence of CK/CH/SD09/005 was compared with reference IBV strains retrieved from GenBank. The phylogenic relationship between CK/CH/SD09/005 and the reference strains was analyzed based on S1 gene sequences. The complete genome of CK/CH/SD09/005 consisted of 27691 nucleotides (nt), excluding the 5' cap and 3' poly A tail. The whole-genome of CK/CH/SD09/005 shared 97 - 99% nucleotide sequence homology with the GX-NN09032 strain, which was the only complete genome that was closely related to CK/CH/SD09/005. When compared with all reference strains except GX-NN09032, CK/CH/SD09/005 showed the highest similarity to ck/CH/LDL/091022 and SDIB821/2012 (QX-like) in the replicase gene (Gene 1) and 3'UTR, with a sequence identity rate of 97% and 98%, respectively. However, CK/CH/SD09/005 exhibited lower levels of similarity with ck/CH/LDL/091022 and SDIB821/2012 in S-3a-3b-3c/ E-M-5a-5b-N with a sequence identity of 72% - 90%. CK/CH/SD09/005 showed the highest level of nucleotide identity with Korean strain 1011, and Chinese strains CK/CH/LXJ/02I, DK/CH/HN/ZZ2004 and YX10, in ORF 3c/E (97%), 5a (96%), 5b (99%) and N (96%), respectively. ORFs 3a, 3b and M of CK/CH/SD09/005 exhibited no more than 90% homology with the reference strains, excluding GX-NN09032. The phylogenic analysis based on the S1 gene revealed that CK/CH/SD09/005 and 39 published strains were classified into seven clades (genotypes). CK/CH/SD09/005 was distributed in clade IV with several isolates collected between 2007 and 2012. CK/CH/SD09/005 showed 66% - 69% and 72% - 81% nucleotide identities with the IBV strains of other six clades in the S1 and S2 subunits, respectively. More over, multiple substitutions were found throughout the entire S gene of CK/CH/SD09/005, while insertions and deletions were located within the S1 gene. These results indicated that CK/CH/SD09/005 is a novel variant that may be derived from the QX-like strains that are prevalent in China. Multiple genetic mechanisms, including recombinations, mutations, insertions and deletions, are likely to have contributed to the emergence of this IBV strain.

BACKGROUND:Studies have shown that vacuum sealing drainage can accelerate wound healing through increasing the wound blood flow, but its influence on activated gelatinases in human chronic wound stil lacks corresponding research. OBJECTIVE:To observe the effect of vacuum sealing drainage on the activity of gelatinase during the healing of chronic wounds. METHODS:Total y 96 trauma patients admitted at the People’s Hospital of Hubei University of Medicine from April 2013 to January 2014 were divided into two groups:52 patients in chronic wound group were treated with vacuum sealing drainage and 44 in control group treated with wound drainage at 3 days after removal of breast cancer. In the chronic wound group, exudates from pressure sores and skin necrosis after removal of breast cancer were col ected as samples A and B;exudates from two cases of venous stasis ulcer were col ected as samples C and D;exudates from traumatic skin wounds col ected as sample E. RESULTS AND CONCLUSION:TLC analyzer showed that:after 15-day negative pressure therapy, activities of matrix metal oproteinase 2 in sample A with low activity of gelatinase, matrix metal oproteinase 9 in sample B, matrix metal oproteinase 2 and 9 in samples C, D, E were al increased significantly (P<0.05);however, the activities of matrix metal oproteinase 9 in sample A with high activity of gelatinases and matrix metal oproteinase 2 in sample B were reduced significantly after treatment (P<0.05). In addition, no significant difference was found in the activity of matrix metal oproteinase 2, matrix metal oproteinase 9 and activated gelatinase betweenthe chronic wound group and control group (P>0.05). These findings indicate that the variation of activated gelatinases activity in human chronic wounds may be the reason why the chronic wounds cannot be healed for a long time, but vacuum sealing drainage can regulate the activity of activated gelatinases in chronic wounds.
