RESUMO
Objective:To investigate the correlation between single nucleotide polymorphism ( SNP ) of rs7517847 and rs10489629 on IL-23R gene and susceptibility of ankylosing spondylitis in Jilin.Methods:IL-23R gene polymorphisms of 188 cases on ankylosing spondylitis were detected by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP ) , compared with those of 100 cases of healthy control group.Results:The frequency distribution differences ,between AS group and comparison group of separate genotype and the allele on two SNPs (rs7517847 and rs10489629) both showed statistical significance (P<0.05).Meanwhile, by the assumed genetic way , compared homozygous mutant GG of rs 7517847 with TG+TT, compared homozygous mutant AA of rs10489629 with GA+GG,such frequency distribution difference between the above two groups also showed statistical significance ( P<0.05).Conclusion:Polymorphisms about IL-23R gene of the rs7517847 and rs10489629 are both associated with susceptibility of AS in Jilin.The risk of AS will be increased if the person both with G/A allele and GG/AA genotype , which may be one of susceptive factors by AS.
RESUMO
OBJECTIVE:To put forward some suggestion to improve drug bidding system in China.METHODS:The process of drug bidding system reform and its common problems were analyzed.Game theory and information asymmetry theory were adopted to analyze the root of the problems and to put forward suggestions.RESULTS:Governments indiscriminately expanded the goals of bidding policy and strengthen price factor.They neglected important steps such as logistics distribution.Current single evaluation system can not count the medication order exactly.Delayed received payment of medical institution resulted in many problems of drug purchase.CONCLUSION:Centralized drug bidding system should be improved and enhanced.It also should be connected with relevant medical system reform to standardize drug circulation channels,reduce drug price and reduce the burden of patient.
