RESUMO
Type 1 diabetes mellitus(T1DM)is a disease that seriously harms children′s health.It often occurs in childhood and is a major public health problem all over the world.T1DM can cause damage to multiple systems including nervous, circulatory, urinary systems, etc.The etiology, prevention and treatment of T1DM have become a research hotspot.With the deepening of researches, the influence of T1DM on cognitive function in children has attracted increasing attention.T1DM can damage the brain structure, neurological development and cognitive function of children, influencing intelligence, attention, memory, executive function, etc.This paper reviews the recent researches between T1DM and cognitive function of children, so as to improve the awareness of pediatricians.
RESUMO
Objective: To evaluate color velocity imaging-quantitative method (CVI-Q) in estimating cerebral hemodynamic change in patients with cerebral infarction. Methods: The carotids of 60 normal people and 40 cerebral infarction patients were detected by CVI-Q. We observed endangium thickness and atheromatous plaques,and measured the diameter (d), peak velocity(Vmax), resistance index(RI) and blood flow volume(Q) of the common carotid arteries. Results: In cerebral infarction group there were 75% cases with endangium thickening to different degrees, 45% cases with atheromatous plaques and 71% plaques in carotid enlargement section or bifurcation. The data measured in 2 groups were compared: (1)The d value in cerebral infarction cases increased than that in normal（P<0.05 or P<0.01）; (2)The Vmax reduced in cerebral infarction cases(P<0.05); (3)The RI increased in cerebral infarction cases (P<0.05 or P< 0.01); (4) The Q value reduced in cerebral infarction cases (P<0.01). Conclusion: CVI-Q can be used for detecting cerebral hemodynamic changes and provide quantitative indexes for clinicians to estimate ischemia degree and treatment in cerebral infarction patients.
