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.

Objective To observe the clinical features and prognosis of endogenous bacterial endophthalmitis (EBE).Methods Ten eyes of 10 patients diagnosed with unilateral EBE were retrospectively reviewed,including 7 males and 3 females.The mean age was 57.6± 10.8 years old.Eight patients were with diabetes and 7 of them were diagnosed over 5 years.There were 3 patients with hepatocirrhosis,1 patient with hypertension,and 1 patient with coronary disease.Nine cases had infectious diseases,including liver abscess (7 cases),pulmonary infection (3 cases),erysipelas (1 case) and perianal abscess (1 case).Seven cases had fever history.Culture and drug sensitive tests for aerobic bacteria,anaerobic bacteria and fungal were performed for 9 eyes using vitreous samples from the procedures of vitrectomy and/or intravitreal injection.All patients were treated with broad-spectrum antibiotics and adjusted for drug use according to microbiological culture and drug sensitivity test results.After the diagnosis was established,vitrectomy combined with lens removal was performed in 5 hours (3 eyes) and 24 hours (5 eyes);Vitreous tamponade of C3F8 (1 eye) and silicone oil (7 eyes) was used;At the end of the operation,0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (1 mg) were injected into the vitreous cavity.One eye received intravitreal injection of 0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (mg),one eye received evisceration.During the follow up period from 6 to 24 months,visual function,slit lamp and fundus examinations were performed at each office visit.Results All patients complained of blurred vision and 5 patients had ocular pain.The visual acuity was no light perception (3 eyes),light perception (5 eyes);hand motion (1 eye) and 0.1 (1 eye).Corneal edema was found in all 10 eyes;hypopyon in 8 eyes;diffuse vitreous opacity in 10 eyes,including 3 eyes with retinal detachment.For 8 eyes treated by vitrectomy and intravitreal injection,1 eye was eviscerated due to uncontrolled inflammation.The eye treated with intravitreal injection was enucleated for its uncontrolled inflammation.For 9 eyes received vitreous culture and drug testing,8 eyes (88.9％) had positive results,including 5 eyes with Klebsiellar pneumonia,and 1 eye with Staphylococcus aureus,or Streptococcus agalactiae or Enterococcus faecalis respectively.At last office visit,2 eyes were with no light perception;4 eyes were with hand motion;and 1 eye with visual acuity of 0.1.Conclusions Most of the patients with endogenous bacterial endophthalmitis have systemic predisposing factors.Klebsiella pneumoniae is the leading cause of ocular EBE.Vitrectomy combined with intravitreal injection of antibiotics showed efficacy in treating EBE.

OBJECTIVE To explore the expression of long non-coding RNA (LncRNA) HOTAIR, enhancer of Zeste homolog 2 (EZH2) and vascular endothelial growth factor (VEGF) in nasopharyngeal carcinoma (NPC) and their relationship between HOTAIR and prognosis. METHODS We examined the expression of HOTAIR, EZH2 and VEGF in NPC tissues, and analyzed the clinical significance of HOTAIR expression in patients with NPC. RESULTS We found that the expression of HOTAIR, EZH2 and VEGF in the NPC tissues were significantly higher than those in the chronic nasopharyngitis tissues in the gene and protein levels (U=955,P<0.05). The HOTAIR was positively correlated with VEGF (r=0.599,P<0.001), VEGF was positively correlated with EZH2 (r=0.369, P=0.012), and HOTAIR had no significant correlation with EZH2 (r=0.139,P=0.357). Moreover, HOTAIR expression levels increased with clinical stage progression. CONCLUSION The expression of HOTAIR, EZH2 and VEGF were significantly increased in the NPC tissues, and the expression of HOTAIR was related with the TNM stage, the clinical stage and the short term therapeutic effect of the NPC patients, which indicated that the HOTAIR might be used as a biological indicator to determine the prognosis of the NPC.
