RESUMO
Objective To explore the value of virtual touch tissue quantification (VTQ ) in the diagnosis of pancreas early damage of patients with hyperuricemia(HUA) .Methods Sixty‐five cases of patients with normal glucose tolerance and HUA (HUA group) and 42 cases of patients with HUA and impaired glucose tolerance (IGT group) were included in the study ,and other 150 health subjects were taken as control group .After routine ultrasound examination ,the pancreas shear wave velocity values (Vs) of different groups were measured by VTQ technology ,and the results were analyzed .Results Compared with the control group ,the rate of the abnormai ultrasonogram of pancreas in IGT group showed obvious increasing trend but there was no significantly difference between the other groups(both P >0 0.5) .The Vs of the normal control group ,HUA group ,and IGT group were (1 2.1 ± 0 1.5)m/s ,(1 4.1 ± 0 1.3)m/s and (1 5.9 ± 0 1.5)m/s ,respectively .The Vs of HUA group and IGT group were higher than that of the control group (both P <0 0.5) ,and the Vs of IGT group was significantly higher than that of HUA group ( P <0 0.5) .Conclusions Hyperuricemia may cause pancreas damage ,and with the disease progress ,the pancreas damage became more serious ,and VTQ technology may play an important role on the diagnosis of pancreas early damage in HUA patients .
RESUMO
Objective To investigate the clinical value of echo-tracking(ET) technique in evaluating the carotid elasticity in patients with hyperuricemia and hyperuricemia combined with hyperlipidemia.Methods One hundred and twenty patients with hyperuricemia were divided into two group:group of hyperuricemia (group A) and group of hyperuricemia combined with hyperlipidemia (group B).Sixty normal persons were served as the control group.ET was used to measure the carotid artery elastic modulus including stiffness parameters (β),pressure-strain elastic modulus (Ep),arterial compliance (AC),augmentation index (AI) and pulse wave conducting velocity (PWVβ).Then the statistical data were analyzed to observe the changes of each parameter.Results In the comparison of three groups,elastic function index β,Ep,PWVβ and AI in group A and group B were higher than those of control group (P ＜0.05) ;however,AC was lower than that of control group (P ＜ 0.05).Compared with group A,elastic function index β,Ep,PWVβ,AI was higher in group B,while the AC was lower than that of group B (P ＜0.05).Conclusions ET may be helpful to prevent atherosclerotic changes and to provide the basis for the clinical diagonosis and treatment atherosclerotic changes.
RESUMO
Objective To evaluate the significance of color Doppler ultrasound examination of renal blood flow combined with the detection of bone morphogenetic protein-7(BMP-7)in early diagnosis of type 2 diabetic nephropathy.Methods Blood BMP-7 level was tested in 90 patients with type 2 diabetic nephropathy and 30 controls,and parameters of renal blood flow were measured by color Doppler ultrasound examination.Blood BMP-7 level as well as resistant index(RI)of segmental renal artery(SRA)and interlobar renal artery(IRA),were compared between these two groups.Results Compared with controls,blood BMP-7 level gradually decreased with the aggravation of diabetic kidney damage(P＜0.01).The peak systolic velocity(Vmax)and the end diastolic velocity(Vmin)of SRA and TRA were slowed gradually,while RI increased(P＜0.01).Blood BMP-7 level was negatively correlated with IRA's and SRA's RI of IRA and SRA(r =-0.603,P＜0.01;r =-0.652,P＜0.01).Conclusions Color Doppler ultrasound examination of renal blood flow combined with detection of BMP-7 might play an important role in early diagnosis of type 2 diabetic nephropathy.
