The peak systolic velocity (PSV) of the renal artery, resistant index of interior artery of kidney,and long axis of kidney of each patient were obtained. Under the double-blind condition, accuracy and diagnostic index of CDU for diagnosing RAS were evaluated according to the standard of renal arteriography, magnetic resonance angiography or computerized tomography angiography. Results The sensitivity of CDU for diagnosing RAS was 60%, specificity was 83%, positive predictive value was 83%, and negative predictive value was 61%. Long axis of kidney in patients with RAS was shorter than that in the healthy ones. The PSV in patients with RAS was higher than that in the healthy ones, and the resistant index of section artery of kidney in patients with RAS was lower than that in the healthy ones. Conclusion CDU is an easy and reliable non-invasive examination for early diagnosis and screening of RAS and for evaluating a short-or long-term therapeutic effect.

Methods A total of 14 New-Zealand white rabbits were intravenous-injected with doxorubicin with a dosage of 3 mg/kg intravenously once a week, and the accumulative dose was 30 mg/kg. Before the medication and at the 4th and 10th weekend after the medication, the serum levels of cardiac troponin I (cTnI) and brain natriuretic peptide (BNP) were measured; left ventricular ejection function (LVEF) and left ventricular fractional shortening (LVFS) were performed on the rabbits respectively. At the 10th weekend, the pathological changes of cardiac tissue and the apoptosis of myocardial cell were detected. Results The levels of cTnI and BNP significantly increased (Plt;0.05), and the LVEF and LVFS markedly decreased (Plt;0.05) after the administration of doxorubicin. Uneven vacuolar degeneration and edema of cardiocytes could be observed with a wide cell spaces and inflammatory cell infiltration in the histopathological slices. Conclusion The combined application of heart sonography with the detection of the serum levels of cTnI and BNP can evaluate the degree of myocardial damage of the rabbits models very well.
