Objective To investigate the relationships between Glucokinase (GCK) gene 6 (tag single-nucleotide polymorphisms,tagSNPs)sites which named rs12702070,rs2971672,rs2268569,rs2268573,rs2300587 and rs1476891 polymorphisms and type 2 diabetes in Chinese Southern Han Population.Methods This study was designed as a case-control.499 type 2 diabetes patients and 499 healthy controls were chosen.All subjects were from August 2013 to December 2014 in Zhongshan Affiliated Hospital of Sun Yat-sen University.6 GCK tagSNPs sites were analyzed by improved multiple ligase detection reaction (iMLDR),and genotype and allele frequency between T2D group and healthy controls could be determined by chi-square test,logistic regression analysis,and tagSNPs were further analyzed under three genetic modes(dominant,recessive and additive).What's more,Haploview software was used to construct the haplotype of 6 GCK tagSNPs and the linkage disequilibrium (LD) and relationship between various GCK haplotype and T2D susceptibility could be analyzed.Results Genotype distribution of rs2268573,rs2300587,rs2268569 and rs1476891 (x2 were 3.361,2.076,0.582 and 0.918 respectively,all P ＞0.05) and allele frequency (x2 were 0.222,1.980,0.590 and 0.851 respectively,all P ＞ 0.05) in T2D group were no significant differences with health controls.Significant differences in genotype distribution of rs2971672 and rs12702070 (x2 were 6.896 and 7.990 respectively,all P ＜ 0.01) and allele frequency (x2 were 4.708 and 5.979,P ＜ 0.05 and P ＜ 0.01 respectively) were observed between T2D group and health controls.Under dominant model (rs2971672:OR =1.74,95％ CI =1.17-2.57,P ＜ 0.01;rs12702070:OR =1.54,95 ％ CI =1.17-2.04,P ＜ 0.01) and additive model (rs2971672:OR =1.51,95 ％ CI =1.06-2.14,P ＜ 0.05;rs12702070:OR =1.26,95％ CI =1.04-1.52,P ＜ 0.05),Genotype distribution of rs2971672 and rs2971672 in T2D were significantly different from health controls.There are two LD domains in 5 tagSNPs among those 6 sites of GCK gene.There are three main haplotypes(TC,TA,CA)in rs2971672 and rs2300587,and four main haplotypes (TAG,TGG,TAT,CGG) in Rs2268569,rs12702070 and rs1476891.Although TAG,TGG,TAT and CGG have no relevance to the individual risk of T2D (P ＞ 0.05),haplotype TA and CA reduce the individual risk of T2D with OR 0.81 (95％ CI:0.66-1.00,P＜0.05) and0.78 (95％ CI:0.62-0.98,P ＜0.01)respectively.Conclusions The results indicated that GCK gene 2 tagSNPs sites included rs2971672 and rs12702070 imparts susceptibility to T2D in Han Chinese,but not rs2268573,rs2300587,rs2268569 and rs1476891.Haplotype TA and CA in rs2971672 and rs2300587 reduce the individual risk of T2D and four main haplotypes (TAG,TGG,TAT,CGG) in rs2268569,rs12702070 and rs1476891 have no relevance to T2D.

Objective:To study the application of the best evidence of dysphagia recognition in acute stroke patients.Methods:The study was performed guided by JBI evidence-based continuous quality improvement pattern, including evidence acquisition, baseline audit, evidence implementation and re-audit. Data were collected by using field observation, questionnaire survey and review of nursing records. 80 patients and 18 nurses were recruited in the study. Barriers to evidence implementation and available solutions were analyzed. Before and after the application of evidence, the compliance of audit criterion, screening rate of swallowing disorder, screening accuracy, screening record rate and knowledge of nurses were compared.Results:Before and after the implementation of evidence, the compliance of all audit criterion was 0-33.3% and 95.0%-100.0%, and had a significant difference ( P<0.05). The dysphagia recognition knowledge score was improved from 40-80(60.56±10.69) to 60-100 (82.78±10.18) and had a significant difference ( t value was -6.39, P<0.05). The screening rate for dysphagia increased from 7.5% to 95.0%, with statistically significant difference ( χ2 value was 119.10, P<0.05). The screening accuracy was 100%, and the screening record rate was 97.4%, only 4 of the 24 patients at risk of dysphagia developed pulmonary infection. Conclusion:The application of the best evidence of dysphagia recognition in acute stroke patients can improve the nurses′ ability of dysphagia screening and improve nursing practice in dysphagia management.
