ABSTRACT

Objective To research and develop the immunochromatographic detection technology of upcon-verting nanoparticles(UCNP)-based rapid fluorescence quantitative procalcitonin (PCT ) detection .Methods UCNP (NaYF4 :Yb3+ ,Er3+ ) was prepared by solvothermal method ,which was the compound of rare earth yt-terbium and erbium with four fluorine sodium yttrium .UNCP was conducted the modification and silica (SiO2 ) packing by using the reverse microemulsion method .Then the PCT determination method was estab-lished by using the dry-type immunochromatographic technology .Results The water-soluble UCNP with good dispersibility was successfully prepared by using the reverse microemulsion method .The lowest detection limit for detecting PCT by UCNP-based dry-type immunochromatographic technology was 0 .02 ng/mL ,the linear range was 0 .05 -44 .00 ng/mL ,the intra-batch and inter-batch coefficients variable(CV) were <10%and 13% respectively .Conclusion UCNP-based immunochromatography technology is a rapidly and sensitively effective method for quantitatively detecting serum PCT .

ABSTRACT

Objective To explore the correlation between resistins rs2161490and rs1423096 genotype with type 2 diabetes mellitus (T2DM)in Guangdong.Methods Collected 178 blood of newly diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2015 to November 2015 as the patient group and 192 blood of healthy physi-cal examination as the control group.Analysis of the two groups of gene distribution frequency was to reach the genetic equi-librium,comparative two gene loci frequencies of resistin rs2161490 and rs1423096 in case group and control group was sta-tistically significant,and compared the distribution frequency of rs2161490 locus T→C and rs1423096 locus A→G between the patient group and the control group.Then made a logistic regression analysis:analysing the risk two loci each genotype of resistin rs2161490 and rs1423096 to T2DM,adjust of the gender and age,and the changes of the risk of the two variables. Comparative blood lipids biochemical indexes between case group and the control group,mode the correlation analysis be-tween TG,CHOL,HDL-C and LDL-C levels of serum lipids in patients with rs2161490 and rs1423096 each genotypewere performed.Results The sample was consistent with Weinberg Hardy’s law of inheritance,which was representative of the population,comparing two gene loci frequency of resistin rs2161490 and rs1423096 of case group and control group:com-parinng CT,TT,CC of rs2161490 genotype,there was no statistically significant difference (P=0.834,>0.05),and com-parinng AA,AG,GG of rs2161490 genotype,there was no statistically significant difference (P=0.960,>0.05).Each gen-otypes with T2DM risk analysis,there was no statistically significant difference(P>0.05).Adjusting the risk change after the two variables,gender and age,there was no statistically significant difference (P>0.05);TG,CHOL,HDL-C and LDL-C in each of the genes expression levels correlation analysis,there was no statistically significant difference (P>0.05).Con-clusion Analysis results showed that the frequency of two loci all genotypes in the case group and control group were no statistical significance (P>0.05).The risk of two loci gene type of rs2161490 with rs1423096 and type 2 diabetes were be-fore and after the covariate adjustment had no statistical significance (P>0.05 ).Each genotype of rs2161490 with rs1423096 and lipid levels had no statistical significance (P>0.05).Thus infer that two genotypes is not risk for type 2 dia-betes genes in guangdong area.

ABSTRACT

Objective To explore the relationships between resistin rs1477341 , rs3219175 and type2 diabetes mellitus (T2DM) in Guangdong. Methods 180 patients of diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2013 to December 2014 were enrolled in the study as the treatment group and another 180 subjects taking health examination as the control group. The genotype distributions of rs1477341 locus A/T, rs3219175 locus A/G were compared and the relationship between the genotypes and T2DM were anlysed by the logistic regression. Results The frequencies of the rs1477341, rs3219175 locus genotype reached the genetic equilibrium, showed their representativeness of a population group. The frequency distribution of rs1477341 genotype was statistically insignificant across the two groups (P > 0.05). The frequency of rs3219175 genotype AA+AG was decreased while genotype GG increased significantly compared to the control group (P < 0.05). The logistic regression results suggest genotype GG may increase disease risk of T2DM which the morbidity rate of AG homozygote was 0.630 times as high as that of GG homozygote (OR =0.630, 95%CI:0.405 ~ 0.980, P < 0.05) and the morbidity rate of GG homozygote was 1.551 times as higher as that of AA+AG homozygote (OR = 1.551, 95%CI:1.016 ~ 2.368, P < 0.05). Conclusions rs1477341 genotype has no correlation with T2DM among the population in Guangdong , but rs3219175 genotype does. GG may have a higher susceptibility to T2DM.
