Changes of erythrocyte CRI genomic density polymorphism and erythrocyte immune function in children with Kawasaki disease / 临床儿科杂志

Objective To explore the heredity susceptibility of children to Kawasaki disease (KD) through studying expression and genomic density polymorphism of peripheral erythrocyte complement receptor-1 (ECRI). Methods Thirty cases of KD patients and 28 cases of healthy children were included in this study. The rates of red blood cell (RBC)-C3bRR and RBC-ICR were detected by method described elsewhere. The ECR1 activity and genomic density polymorphism were detected by Hind Ⅲ restriction enzyme digestion polymerase chain reaction-restriction fragment length polymorphism. Results Rates of RBCoC3bRR of KD patients during the acute phase was significantly lower than that of the control group (P < 0.01), and remained lower than the control group during the recovering phase (P < 0.05). The rates of RBC-ICR were significantly higher in KD patients than that of the control group (P < 0.05). Frequencies of HL and LL genotypes of KD patients were more than those of the control group (P < 0.01). A significant difference was found in the frequency distribution of ECR1 genotype between the two groups (P < 0.01). L allele frequency in the patient group was higher than that in the control group. Conclusions Depressed RBC immune function in KD patients may be linked to the high frequency of L allele, which implies the genomic density polymorphism of ECR1 play an important role in determining susceptibility to Kawasaki disease.

The change of plasma endothelin and atrial natriuretic peptide in heart failure infants and the effect of applying milrinone / 中国医师进修杂志

Objective To determine the change and effect of milrinone on the concentration of plasma endothelin(ET)and atrial natriuretic peptide(ANP)in congestive heare failure(CHF)infants.Methods Forty-one CHF infants' plasma ET and ANP concentration were determined before and after having received milrinone intravenously,meanwhile compared with that of 40 healthy infants as control.Results The concentration of plasma ET and ANP in CHF infants were obviously increased,which has greatly decreased after intravenous dripping of milrinone.The difference has statistic significance.Conclusion The concentration of plasma ET and ANP in CHF infants are greatly increased and could be lowered by treating with milrinone.
