Objective To investigate the effect of comprehensive psychological intervention on cooperation degree with intravenous infusion of preschool children. Methods 240 children patients with intravenous infusion were divided into the observation group and the control group with 120 cases in each group.Children patients in two groups were all given venipuncture by two nurses who had more than 5 years of working experience,skilled venipuncture technique and were good at doing mental work for children.The control group was given intravenous infusion directly after venipuncture without giving any psychological intervention.The observation group was given comprehensive psychological intervention before venipuncture.The different psychological behavioral reactions during the venipuncture were evaluated.The cooperation degree and the first-time success rate of venipuncture for the two groups were taken for statistics. Results The psychological behavioral reactions of the observation group were as followed:the active type was 51.67%,the tension type was 30.83%,and 7.50% for the type of fear,the compulsive type was 10.00%.Compared with the control group,the difference was significant.The cooperation degree with intravenous infusion was 82.50%,the difference was significant compared with the control group.The first-time success rate in the observation group was 86.67%,higher than 75.83% in the control group. Conclusions Psychological interventions according to the behavior and psychological reaction of preschool children with intravenous infusion can alleviate the negative emotions and improve the cooperation degree of preschool children.

Objective To compare the advantages and disadvantages of SNPscan and Sanger sequence which are both used to detect the common deafness gene mutations in non-syndromic hearing loss (NSHL) in Gansu Province.Methods Peripheral blood samples were obtained from Dongxiang, Yugu and Baoan people with moderately severe to profound sensorineural hearing loss in Gansu province to extract genomic DNA.SNPscan was used to detect the 115 mutations in the common pathogenic GJB2 gene, SLC26A4 gene and mtDNA gene.Results We used the SNPscan to screen the mutation of GJB2 gene,mtDNA A1555G and mtDNA C1494T, SLC26A4 gene of sensorinural deafness patients from Gansu Province.The mutation rate of these three genes was 23.18% (35/151), and the mutation rate of Dongxiang, Yugu, Baoan was 21.31% (26/122), 54.54% (6/11), 16.67% (3/18), respectively.Compared with the Sanger sequence, the results were statistically insignificant(P>0.05).The detection rates in the three genes of SNPscan were 11.26% (17/151), 1.32% (2/151) and 0.66% (1/151),respectively , and the detection rates of Sanger sequence were 9.93% (15/151), 1.32% (2/151) and 0.66% (1/151) ,respectively.The results of the two methods were compared.The results were statistically insignificant (P>0.05).Time, cost and flux, SNPscan method is superior to Sanger sequencing.Conclusion Compared with the Sanger sequence, SNPscan is more lighter in workload, less time-consuming, higher-throughput, lower cost, and can get more meaningful mutations and reduce the false negative rates.

Objective To investigate the prevalence and characteristics of GJB2 mutations in Uygur,Hui, Kazak and Kirgiz ethnic patients with non-syndromic hearing loss(NSHL)from the Xinjiang Uygur Autonomous Region of China.Methods With the permission,we collected 565 patients with moderately severe to profound sen-sorineural hearing loss,including Uygur,Hui,Kazak and Kirgiz ethnic minorities from 14 cities of Xinjiang.Pe-ripheral blood samples were obtained to extract genomic DNA.The SNP classification technology was for common pathogenic GJB2 gene mutations.ResuIts The pathogenic allele frequency of GJB2 gene were 10.16%(87/856 ), 15.85%(13/82),10.16%(13/128),1.56%(1/64)in the NSHL patients of Uygur,Hui,Kazak and Kirgiz minori-ties,respectively.And these differences were statistically significant (χ2 =8.140,P=0.043).c.235delc was only found in the Uygur and Hui with the allele frequency of 5.14 %(44/856)and 13.41 %(11/82),respectively.And c.35delG was found in Uyhur,Hui,Kazak and Kirgiz with allele frequencies were 3.15% (27/856),1.21% (1/82),8.59%(11/128)and 1.56% (1/64),respectively.ConcIusion GJB2 gene mutations had a higher incidence in Xinjiang NSHL patients,GJB2 gene mutation spectrum had differences in Uygur,Hui,Kazak and Kirgiz,c. 235delC the hotspot mutation region in Uygur and Hui nationalities NSHL patients,while c.35delG is the hotspot mutation region in NSHL patients of Uygur,Kazak and Kirgiz ethnicities.
