This study aims to investigate the preventive effect of oral nicorandil on contrast-induced nephropathy (CIN) in patients with renal insufficiency undergoing elective cardiac catheterization. A total of 240 patients with an estimated glomerular filtration rate (eGFR) of 60 mL/min or less, who were undergoing elective cardiac catheterization, were randomly assigned to nicorandil group (n = 120, 10 mg nicorandil, three times daily from 2 days before to 3 days after procedure) or control group (n = 120, matching placebo as the same method). The primary endpoint was the incidence of CIN defined as 25 % increase in serum creatinine (SCr) from baseline or 44 μmol/L (0.5 mg/dL) increase in absolute value within 72 h after exposure to contrast medium. The secondary endpoints were: (1) the changes of SCr, Cystatin-C (Cys-C) and eGFR within 72 h; (2) major adverse events (MACE) occurring within 30 days. Baseline characteristics of the patients in the two groups were similar. The incidence of CIN was significantly lower in nicorandil group compared with control group (6.67 vs. 17.5 %, P = 0.017). Compared with the control group, nicorandil group tended to have a lower SCr and Cys-C levels as well as a higher eGFR at 48 h after the procedure (all P < 0.05). There was no difference about the incidence of MACE within 30 days between nicorandil group and control group (4.16 vs. 5.83 %, P = 0.767). Multivariate logistic analysis showed that nicorandil was an independent protective factor against CIN (OR = 0.260, 95 % CI = 0.1-0.676, P = 0.006). Therefore, we concluded that oral nicorandil was associated with a decline in the incidence of CIN in patients with renal insufficiency undergoing elective cardiac catheterization.
Background: Circular RNA (circRNA) has an essential regulatory role in the chemotherapy resistance of cancers. Nevertheless, the role of circRNA nuclear receptor-interacting protein 1 (circNRIP1) in the paclitaxel (PTX) resistance of ovarian cancer (OC) remains unclear. Material and Methods: The circNRIP1, miR-211-5p and homeobox C8 (HOXC8) expression levels were assessed using qRT-PCR. The PTX resistance of cells was measured by 3-(4, 5-dimethylthiazolyl-2-yl)-2-5 diphenyl tetrazolium bromide (MTT) assay. Furthermore, cell proliferation, apoptosis, migration and invasion were detected by colony formation assay, flow cytometry and transwell assay, respectively. Moreover, the protein levels of proliferation, apoptosis, metastasis-related markers and HOXC8 were determined by Western blot (WB) analysis. Tumor xenograft models were constructed to explore the influence of circNRIP1 on OC tumor growth. The interaction between miR-211-5p and circNRIP1 or HOXC8 was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. Results: CircNRIP1 was highly expressed in PTX-resistant OC tissues and cells. Silencing of circNRIP1 repressed the PTX resistance of OC cells in vitro and OC tumor in vivo. Furthermore, circNRIP1 sponged miR-211-5p, and miR-211-5p inhibitor could reverse the inhibitory effect of circNRIP1 knockdown on the PTX resistance of OC cells. In addition, miR-211-5p targeted HOXC8, and HOXC8 overexpression could reverse the suppression effect of miR-211-5p on the PTX resistance of OC cells. Additionally, the expression of HOXC8 was regulated by circNRIP1 and miR-211-5p. Conclusion: CircNRIP1 silencing could inhibit the PTX resistance of OC via regulating the miR-211-5p/HOXC8 axis, showing that circNRIP1 might be a potential target for OC resistance treatment.
Intravenous lipo-PGE1 can reduce the incidence of PMI following elective PCI in patients with unstable angina. The benefit of lipo-PGE1 may be associated with the effects of anti-inflammation as well as improvement in coronary microvascular perfusion.
Background: The aim of this study was to explore the impact of 6-Fr and 7-Fr sheaths on the incidence of long-term radial artery occlusion (RAO) after trans-radial coronary intervention (TRI). , patients with ischemic heart disease including acute myocardial infarction and true bifurcation lesions were randomly assigned to 6-Fr group and 7-Fr group immediately after coronary angiography in a 1:1 ratio. The radial artery diameters were observed by ultrasound examination one day prior to TRI as well as at 30 days and 1 year after TRI. The primary endpoint was the incidence of RAO at 1-year after TRI. The secondary endpoints were the incidence of local vascular complications during hospitalization and changes of radial artery diameters within 1-year after TRI between the two groups. Additionally, multivariate logistic regression analysis was used to explore potential factors related to the incidence of long-term RAO after TRI. Results: A total of 214 patients were enrolled and randomly assigned to 6-Fr group (n = 105) or 7-Fr group (n = 109). There was no significant difference in the incidence of RAO at 1-year after TRI (8.57% vs. 12.84%, p = 0.313). Moreover, no significant difference was observed in the incidence of local vascular complications during hospitalization (20% vs. 24.77%, p = 0.403). After 1-year follow-up, no significant difference was found in radial artery diameters (2.63 ± 0.31 mm vs. 2.64 ± 0.27 mm, p = 0.802). Multivariate logistic analysis revealed that repeated TRI was an independent risk factor of long-term RAO 1 year after TRI (OR = 10.316,, p = 0.001). Conclusions: Compared to 6-Fr sheath, 7-Fr sheath did not increase short-term or long-term incidence of RAO after TRI. (Cardiol J XXXX; XX, X: xx-xx)
