Comparison of intravascular ultrasound-guided with angiography-guided double kissing crush stenting for patients with complex coronary bifurcation lesions: Rationale and design of a prospective, randomized, and multicenter DKCRUSH VIII trial.

Background: Double kissing (DK) crush approach for patients with coronary bifurcation lesions, particularly localized at distal left main or lesions with increased complexity, is associated with significant reduction in clinical events when compared with provisional stenting. Recently, randomized clinical trial has demonstrated the net clinical benefits by intravascular ultrasound (IVUS)-guided implantation of drug-eluting stent in all-comers. However, the improvement in clinical outcome after DK crush treatment guided by IVUS over angiography guidance for patients with complex bifurcation lesions have never been studied in a randomized fashion.

[Feasibility and outcome of rotational atherectomy for treating resistant chronic total occlusions].

Objective: To assess the application of rotational atherectomy to improving the success rate and outcome of percutaneous recanalization of resistant chronic total occlusion (CTO), i.e. the guidewire could cross the lesion but it is impossible to advance any device over the wire through the occluded segment.

Optimal dosages of fluoxetine in the treatment of hypoxic brain injury induced by 3-nitropropionic acid: implications for the adjunctive treatment of patients after acute ischemic stroke.

Aim: The serotonin selective reuptake inhibitor fluoxetine (Flx) has tried to treat patients suffered acute ischemic stroke because of its possible neuroprotective actions. However, besides the neuroprotective effect, Flx at high concentration also induces some actions in contradiction to neuroprotection in the brain. The purpose of this study was to investigate whether Flx presents neuroprotective effect against 3-nitropropionic acid (3-NP)-induced hypoxic brain injury, and what is the most suitable dosage of Flx.
