Objective To assess the value of contrast-enhanced ultrasound (CEUS) on quantitative analysis of re?nal cortex perfusion in hypertensive rabbits model. Methods Hypertensive rabbit modal (n=10) were established by inject?ing N-nitro-L-arginin methylester (L-NAME). CEUS and Cystatin C (CysC) serum level analysis were performed at differ?ent time points:before and the 2nd, 4th, 6th and 8th week after injecting L-NAME. Time-intensity curve and area under curve (AUC) were analyzed quantatively while correlation of AUC and CysC were also analyzed. Results Serum level of Cys C in?creased significantly at the 6th week after L-NAME administration which is earlier than the increase of serum levels of Scr and BUN. AUC decreased at first then increased after L-NAME administration. Upon addition of L-NAME, rise time (RT) and peak intensity (PI) decreased while mean transit time (MTT), time from peak to one half (HPT) and time to peak (TTP) in?creased. Our study confirmed a positive correlation between AUC and Cys C (r=0.950, P<0.001). Conclusion Setting up rabbits model by L-NAME is convenient and reproducible, which is an useful tool in experimental study of preclinical and clinical phase of hypertensive renal injury. CEUS combining with CysC serum level analysis is considered as an effective technology for evaluating renal function in hypertensive patients.

OBJECTIVE:
To study the effect of down-regulating miR-488 targeting Jag1 on the injury of hypoxia-reoxygenation myocardial H9c2 cells.
METHODS:
A hypoxic-reoxygenated myocardial H9c2 cell injury model was constructed. miR-488 inhibitor was used to transfect the cells. CCK-8 method and flow cytometry were used to detect cell proliferation and apoptosis in each group. Lactate dehydrogenase (LDH), superoxide dismutase (SOD), malonaldehyde (MDA), catalase (CAT) levels were detected. Western blotting was used to detect the expression of Bcl-2 associated X Protein (Bax) and B cell lymphoma/lewkmia-2 (Bcl-2). Target genes of miR-488 were predicted, and a luciferase reporter system was used to verify the targeting relationship between the two. Myocardial H9c2 cells were co-transfected with miR-488 inhibitor and Jag1 siRNA, and treated with hypoxia and reoxygenation, cell proliferation, apoptosis, LDH, SOD, MDA, CAT levels, and Bax, Bcl-2 protein expression were detected.
RESULTS:
The expression of miR-488 in the hypoxia-reoxygenated myocardial H9c2 cells was increased, along with reduced cell proliferation, increased apoptosis, increased Bax protein expression, decreased Bcl-2 protein expression, increased MDA, decreased CAT and SOD, and increased LDH level in the supernatant of cell culture. When myocardial H9c2 cells were transfected with miR-488 inhibitor and treated with hypoxia and reoxygenation, the expression of miR-488 was decreased, along with increased cell proliferation, decreased apoptosis, decreased Bax protein expression, increased Bcl-2 protein expression, decreased MDA, increased CAT and SOD, and decreased LDH level in the supernatant of cell culture. Down-regulation of miR-488 could target and down-regulate Jag1 expression. And Jag1 siRNA could reverse the effect of miR-488 inhibitor on the proliferation, apoptosis, LDH, SOD, MDA, CAT levels and the expression of Bax and Bcl-2 of hypoxic-reoxygenated myocardial H9c2 cells.
CONCLUSION
Down-regulating miR-488 targeted Jag1 can attenuate hypoxia-reoxygenation induced myocardial H9c2 cell injury.
