Objective To genotype Yersinia pestis and explore intrinsic relationship among different ecotypes of Yersinia pestis in Yunnan foci.Methods A total of 171 strains from three types of Yersinia pestis,house mouse,wild-type mouse and Yulong Yersinia pestis,were tested.Twenty-three different regions (DFR) were used to genotype and cluster analysis was performed using BioNumerics 5.0.Results A total of 171 Yersinia pestis were divided into 7 genotypes by 23 DFRs,which were Genomovar5,Genomovar7,Genomovar9 and 4 newly discovered genotypes.The genotypes of all Yulong plague were Genomovar5.The genotypes of the 16 strains of wild-type mouse plague (the highland of northwestern Yunnan Province type) were divided to 3 genotypes,13 of them were Genomovar 7,2 of them were Genomovar9,and 1 of them was newly discovered genotype Genomovaryn1.The genotypes of the 148 strains of house mouse plague(the residential area of Yunnan and Fujian Provinces type) were divided into 4 genotypes,145 of them were Genomovar9,and 3 of them were newly discovered including Genomovar-yn2,-yn3 and-yn4.The ecological typing results of clustering showed genotype of Yulong plague was similar to the highland of northwestern Yunnan Province type(wild-type mouse plague),and the percentage of similarity was up to 87.20%,but only up to 73.75% to the residential area of Yunnan and Fujian Provinces type (house mouse plague).The genotypes of 2 wild-type strains of the highland of northwestern Yunnan Province type(wild-type mouse) and main genotypes of the residential area of Yunnan and Fujian Provinces type(house mouse)were Genomovar 9.The genotype of Genomovar-yn 1 of the highland of northwestern Yunnan Province type was similar to Genomovar 7,but lack of DFR 11.The genotypes of Genomovar-yn2,-yn3 and-yn4 of the residential area of Yunnan and Fujian Provinces type were similar to Genomovar 9,but lack of DFR 10,DFR 9 and DFR 11,respectively.Conclusions One newly genotype strain is found in wild-type mouse plague and 3 newly genotype strains are founded in house mouse plague.Wild-type mouse strains are founded in the house mouse strains.The similarity of genotype between Yulong plague and the highland of northwestern Yunnan Province type (wild-type mouse plague) is high while the similarity between Yulong plague and the residential area of Yunnan and Fujian Provinces type(house mouse plague) is low.

AIM: To observe clinical efficacy of the intravitreal injection of conbercept treatment for exudative age -related macular degeneration.
METHODS:Prospective study. Totally 112 senile patients (112 eyes) with exudative macular degeneration were randomly divided into study group and the control group, 56 cases in each group. The study group were treated with intravitreal injection of conbercept. The control group received conservative treatment. Uncorrected visual acuity and foveal retinal thickness were observed before and after treatment in the two groups.
RESULTS: Visual acuity of study group improved significantly, and the most obvious improvement was observed at 6mo after treatment. Foveal retinal thickness of study group was reduced after treatment, and the most obvious decrease was observed at 6mo after treatment.CONCLUSION: Intravitreal injection of conbercept can improve visual acuity reduced foveal thickness in senile patients with exudative age - related macular degeneration.

Objective To investigate the effects of interleukin?17A on kidney injury induced by paraquat(PQ). Methods Seventy?two ICR mice were randomly divided into 3 groups:NS,PQ,and PQ+Ab (n=24 for each). The PQ?poisoning model was established by administering a gavage of PQ solution;mice in the PQ+Ab group were then administereda dose of anti?IL?17A antibody 2 hours later by i.p. injection,whereas the NS group were administered a corresponding volume of normal saline instead.The mice were killed at 8,24,48,or 72 h to obtain renal tissues and serum. An enzyme?linked immunosorbent assay(ELISA)was used to determine serum IL?17A,serum creatinine(SCr),and blood urea nitrogen (BUN)levels.Chemical colorimetry was used to detect the viability of myeloperoxidase(MPO )in renal tissue,and hematoxylin?eosin(HE)stain?ing was used to observe the renal pathologic changes. Immunohistochemistry(IHC)and PCR were used to examine IL?17A expression in renal tis?sues. Results Serum IL?17A,renal tissue MPO viabilities,BUN,and SCr were increased in the PQ and PQ+Ab groups,compared to those in the NS group(P<0.01). However,the above?mentioned parameters were lower in the PQ+Ab group than in the PQ group(P<0.01). Conclusion IL?17A promotes mouse kidney injury induced by acute PQ?intoxication through activating and/or recruiting neutrophils;therefore,blockade IL?17A,with antibody can attenuate the injury.
