ABSTRACT

Apresentamos o caso debutante na América Latina de reparos transcateteres edge- to-edge nas valvas mitral e tricúspide em um único procedimento em paciente de alto risco para cirurgia. A paciente evoluía com insuficiência cardíaca e limitações em suas atividades diárias quando foi submetida ao procedimento, no qual foram realizados os reparos transcateteres das valvas mitral e tricúspide. Aos 6 meses de evolução, estava assintomática e realizando suas atividades diárias. Debatemos as recomendações mais atualizadas sobre a terapia transcateter para coexistência dessas doenças valvares, assim como expomos as lacunas no conhecimento.


We present the first case in Latin America of transcatheter edge-to-edge mitral and tricuspid valve repair in a single procedure, in a patient at high risk for surgery. The patient progressed to heart failure and limitation in her daily living activities when she was submitted to transcatheter mitral and tricuspid valve repair. Six months later, she was asymptomatic and performing her daily living activities. We discuss the most updated recommendations for transcatheter repair when both valvar conditions coexist, and show the knowledge gaps.

ABSTRACT

Objective:To explore the efficacy and safety of domestic RECO flow restoration device in acute intracranial large-vessel occlusion (LVO).Methods:This study was a multicenter, prospective, randomized, open, controlled trial; 136 patients with acute intracranial LVO at 7 Chinese stroke centers from February 2014 to August 2016 were randomly assigned into an experimental group (thrombectomy by RECO device, n=67) and a control group (thrombectomy by Solitaire device, n=69). The efficacy and safety of patients from the two groups were compared and analyzed. The primary efficacy end point was set as achievement of good recanalization (modified thrombolysis in cerebral infarction [mTICI] grading≥2); the secondary efficacy end points included good prognosis (modified Rankin scale scores≤2 90 d after thrombectomy), time from puncture to achieving good recanalization/time from puncture to final angiogram on condition that good recanalization was not gained, or mortality within 90 d of thrombectomy. The safety end points included any device-related serious adverse events, symptomatic intracerebral hemorrhage or serious adverse events within 24 of thrombectomy. Results:There was no statistically significant difference between the experimental group and the control group in successful rate of good recanalization (91.0% vs. 86.9%), good prognosis rate (62.7% vs. 46.4%), time from puncture to achieving good recanalization/time from puncture to final angiogram on condition that good recanalization was not gained([85.4±47.0] min vs. [89.9±53.3] min), and mortality within 90 d of thrombectomy (13.4% vs. 23.2%, P>0.05). There were no device-related serious adverse events in all patients. No significant differences were found in the incidences of symptomatic intracranial hemorrhage (1.5% vs. 7.4%) or serious adverse events (death [1.5% vs. 1.4%] and brain hernia [4.5% vs. 0.0%]) between the two groups ( P>0.05). Conclusion:The domestic RECO flow restoration device is an effective and safe mechanical thrombectomy stent retriver for acute intracranial LVO.

ABSTRACT

Objective To construct expressing recombinant of recF and recO from Deinococcus radiodurans R1and express the target protein in E.coli BL21(DE)3.Methods recF and recO gene were amplified by PCR from genomic DNA of Deinococcus radiodurans R1 and inserted into expression plasmid vector pET30b(+) to construct pET30b(+)-recF and pET30b(+)-recO.The recombinant plasmids were transformed into E.coli BL21(DE)3 and the recombinant proteins were expressed by the isopropyl-?-D-thiogalactopyranoside(IPTG) and were analyzed with SDS-PAGE.The changes in the survival rate of bacteria in each group before-and after UV-irradiation were calculated.Results The recombinant plasmid pET30b(+)-recO and pET30b(+)-recF was obtained and the recombinant protein could be highly expressed in E.coli BL21(DE)3.Conclusion This study has provided a foundation for further studies and applications of the recombinant RecF and RecO,and initial detection shows that recO and recF gene can increase the resistant ability of E.coli.
