OR: overall pooled OR = 0.781, 95% CI: 0.454-1.343, P = 0.371; m RECIST subgroup OR = 0.584, 95 % CI: 0.349-0.976, P = 0.040; WHO subgroup OR = 1.065; 95% CI: 0.500-2.268, P = 0.870. Serious AEs: overall pooled RR = 1.477, 95% CI: 0.864-2.526, P = 0.154; RCT subgroup RR = 0.680, 95% CI: 0.325-1.423, P = 0.306; observational study subgroup RR = 1.925; 95 % CI: 0.978-3.788, P = 0.058.Conclusions: TARE(90 Y) increased 2-year OS rates in the observational subgroup and resulted in better OR rates, according to m RECIST criteria, in comparison with c TACE. Furthermore, a lower risk of AEs was observed for TARE(90 Y) than for c TACE.展开更多

This study was designed to test the theory that the effectiveness and safety of drug-eluting balloons for the treatment of de novo lesions in small coronary vessels are non-inferior to those of drug-eluting stents. Methods We designed a prospective, multicenter, randomized, controlled clinical trial aiming to assess the effectiveness and safety of the RESTORE R (Cardionovum, Bonn, Germany) drug-eluting balloon (DEB) versus the RESOLUTE R (Medtronic, USA) drug-eluting stent (DES) in the treatment of small coronary vessel disease. This trial started in August 2016. A total of 230 patients with a reference vessel diameter (RVD) 〉 2.25 mm and 〈 2.75 mm were randomly assigned to treatment with a DEB or a DES at a 1:1 ratio. The study was also designed to enroll 30 patients with an RVD 〉 2.00 mm and 〈 2.25 mm in the tiny vessel cohort. Results The key baseline data include demographic characteristics, relative medical history, baseline angiographic values and baseline procedural characteristics. The primary endpoint is in-segment diameter stenosis at nine months after the index procedure. Secondary endpoints include acute success, all-cause death, myocardial infarction, target vessel revascularization, target lesion revascularization and stent thrombosis. Conclusions The study will evaluate the clinical efficacy, angiographic outcomes, and safety of DEBs compared to DESs in the treatment of de novo coronary artery lesions in small vessels.展开更多

Yet, we aimed to explore the effect and possible mech- anism of RD on blood-pressure response to hemorrhagic shock in spontaneously hypertensive rats. Methods: A total of 48 male spontaneously hypertensive rats were randomized to three groups: study group, sham-operation group and control group. RD was achieved by cutting off renal nerves and swabbing phenol on it. Ten weeks after RD, 8 rats in each group were sacrificed to collect the kidney and heart tissues. The remaining rats were subjected to an operation to induce hemorrhagic shock which would lead to 40% loss of total blood volume, and observed for 120 min. The serum concentration of norepinephrine was measured before and three weeks after RD. Results: The blood-pressure and norepinephrine levels were reduced significantly after RD (p 〈 0.05), Systolic blood pressure and diastolic blood pressure of the surgerygroup were higher than those in the sham and control groups at 15, 30 and 45 min after hemorrhagic shock (p 〈 0.05), while no significant difference was observed at 60, 90 and 120 min (p 〉 0.05). Additionally, the beta-1 adrenergic receptor (β1 -AR) in the study group was significantly higher than those in the other two groups (p 〈 0.05) after hemorrhagic shock. Conclusion: This study demonstrated that RD could to some extent improve blood-pressure response to hemorrhagic shock in an established model of severe hemorrhagic shock in spontaneously hypertensive rats. The mechanism might be associated with uo-regulation of β1-AR.展开更多
