1.Alteration of fatty acid components and insulin resistance of red cell membrane in diabetic patients with coronary heart disease
Basic & Clinical Medicine 2001;21(2):166-168
The fatty acid components and microviscosity of erythrocyte membrane in 39 type 2 diabetic patients with and without coronary heart disease(CHD) were examined by high-performance liquid chromatography (HPLC) and fluorescence polarization teachnique,and their relationship with insulin sensitivity index (ISI) and CHD were analyzed.The results showed that contents and composition of erythrocyte membrane arachidonic acid (AA,C20:4)were significantly lower in type 2 diabetic patients with or without CHD than those in control subjects (P<0.01 and P<0.05).The total fatty acids contents were also significantly lower in patients with CHD than those in normal subjects (P<0.05).In patients with or without CHD,erythrocyte membrane microviscosity was significantly increased as compared with the controls (P<0.01 and P<0.05),and it was higher in diabetics with CHD than those without CHD (P<0.05).AA contents of erythrocyte membrane was negatively correlated with microviscosity and positively correlated with insulin sensitivity index (ISI),while the microviscosities were negatively correlated with ISI in diabetics.AA,linoleic acid contents,microviscosity of erythrocyte membrane and ISI were all correlated with the incidence of CHD in diabetics.In diabetic patients,the fatty acid metabolic abnormality could cause the alterations of functions,structures and fluidity of erythrocyte membrane,thus may contributing to increased IRS and might be related to the incidence of CHD.

OBJECTIVEThe study was designed to explore the value of the New York University Pediatric Heart Failure Index (NYU PHFI) for diagnosing and grading chronic heart failure in children.
METHODSTotally 105 children with chronic heart failure or structural heart disease but without signs and symptoms of heart failure were enrolled. They were diagnosed using modified Ross score, NYU PHFI and NT-proBNP, respectively. According to modified Ross score as the referent criteria, the diagnostic value of NYU PHFI in quantifying chronic heart failure severity in children was studied. Furthermore, according to the grading of heart failure using modified Ross score, the area under the ROC curves of NYU PHFI was examined, respectively, in order to find out the optimal cut-off point.
RESULTSNYU PHFI score was positively correlated with the modified Ross score (r = 0.909, P = 0.000). According to modified Ross score, NYU PHFI scores in different severity of heart failure in children differed significantly (F = 80.034, P = 0.000). A significantly positive correlation was found between plasma NT-proBNP and modified Ross score, and between NT-proBNP and NYU PHFI score. Correlation coefficients between plasma NT-proBNP and modified Ross score, and between plasma NT-proBNP and NYU PHFI score were 0.752 and 0.918, respectively. The correlation between NYU PHFI and plasma NT-proBNP was superior to that between modified Ross score and plasma NT-proBNP. According to modified Ross scores of 0 - 2 as being without heart failure, 3 - 6 as mild degree of heart failure, 7 - 9 as moderate degree of heart failure and 10 - 12 as severe degree of heart failure, the areas under the ROC curve of the NYU PHFI diagnosing if heart failure was present, differentiating moderate from mild and severe from moderate heart failure were 0.982, 0.942 and 0.918, respectively, and the sum of sensitivity and specificity was favorite when 6, 10 and 13 scores were set as cut-off value diagnosing the presence of heart failure, differentiating moderate from mild, and severe from moderate heart failure, respectively. According to above classification of heart failure based on NYU PHFI score, plasma NT-proBNP concentration was significantly different in different degree of heart failure (F = 53.31, P < 0.001). Plasma NT-proBNP concentration in those without heart failure was significantly lower than that of mild heart failure, and it was also significantly lower in mild heart failure than that of severe heart failure.
CONCLUSIONNYU PHFI was highly valuable for diagnosing chronic heart failure in children and 0 - 6 scores as being without heart failure, 7 - 10 scores as mild degree, 11 - 13 scores as moderate degree and 14 - 30 scores as severe degree of heart failure could be used as the reference criteria of different severities of heart failure.
