10Primary reperfusion in acute right ventricular infarction: An observational study显示文摘AIM: To investigate the impact of primary reperfusion therapy(RT) on early and late mortality in acute right ventricular infarction(RVI). METHODS: RVI patients(n = 679) were prospectivelyclassified as without right ventricular failure(RVF)(class A, n = 425, 64%), with RVF(class B, n = 158, 24%) or with cardiogenic shock(CS)(class C, n = 96, 12%). Of the 679 patients, 148(21.7%) were considered to be eligible for thrombolytic therapy(TT) and 351(51.6%) for primary percutaneous coronary intervention(PPCI). TIMI 3-flow by TT was achieved for A, B and C RVI class in 65%, 64% and 0%, respectively and with PPCI in 93%, 91% and 87%, respectively. RESULTS: For class A without RT, the mortality rate was 7.9%, with TT was reduced to 4.4%(P < 0.01) and with PPCI to 3.2%(P < 0.01). Considering TT vs PPCI, PPCI was superior(P < 0.05). For class B without RT the mortality was 27%, decreased to 13% with TT(P < 0.01) and to 8.3% with PPCI(P < 0.01). In a TT and PPCI comparison, PPCI was superior(P < 0.01). For class C without RT the in-hospital mortality was 80%, with TT was 100% and with PPCI, the rate decreased to 44%(P < 0.01). At 8 years, the mortality rate without RT for class A was 32%, for class B was 48% and for class C was 85%. When PPCI was successful, the longterm mortality was lower than previously reported for the 3 RVI classes(A: 21%, B: 38%, C: 70%; P < 0.001). CONCLUSION: PPCI is superior to TT and reduces short/long-term mortality for all RVI categories. RVI CS patients should be encouraged to undergo PPCI at a specialized center.Eulo Lupi-Herrera Héctor González-Pacheco úrsulo Juárez-Herrera Nilda Espinola-Zavaleta Eduardo Chuquiure-Valenzuela Ramón Villavicencio-Fernández Marco Antonio Pea-Duque Ernesto Ban-Hayashi Sergio Férez-Santander 2014World Journal of Cardiology2014,6,1:1

16Innovate combination of sevoflurane dilution in dimethyl sulfoxide: A stability study by gas chromatography and nuclear magnetic resonance显示文摘AIM To investigate physicochemical stability of sevoflurane in dimethyl sulfoxide using gas chromatography with a flame ionization detector and nuclear magnetic resonance(NMR).METHODS Undiluted sevoflurane, plus dilutions 1:2, 1:5, 1:10, 1:25, and 1:50 in dimethyl sulfoxide were prepared in a vertical laminar flow cabinet class Ⅱ type B and stored at different temperatures(23 ℃, 6 ℃, and-10 ℃) for 45 d. Sterile 1 mL polypropylene amber syringes to minimize light degradation, caps and needles were used. The presence of sevoflurane and its degradation products in the samples was determined by gas chromatography with flame ionization detector(260 ℃, 40 min), and by ~1H, ^(19) F, and proton-decoupled ^(19) F nuclear magnetic resonance.RESULTS The gas chromatography analysis showed sevoflurane and dimethyl sulfoxide(DMSO) retention times were 2.7 and 13.0 min, respectively. Pure DMSO injection into the column resulted in two additional peaks at 2.1 and 2.8 min. The same sevoflurane peak at 2.7 min was observed in all the dilutions at-10 ℃, 4 ℃ and 25 ℃. The NMR spectra showed signals consistent with the sevoflurane structure in all the dilutions at-10 ℃, 4 ℃ and 25 ℃. In the ~1H spectrum, two signals corresponding to the sevoflurane molecule were observed at 5.12 and 4.16 parts per million(ppm5). In the ^(19)F-NMR spectrum, two signals were observed at-76.77 ppm and-157.13 ppm. In the ^(19)F NMR CPD, two signals were observed at-76.77 ppm and-157.13 ppm. The first one showed a doublet(JF-F = 3.1 Hz) which integrated by six fluorine nuclei from the hexafluoro-isopropyl group. The second signal was integrated by a fluorine atom and showed a septuplet(JF-F = 3.1 Hz).CONCLUSION This study shows that different concentrations of sevoflurane in dimethyl sulfoxide retain their chemical composition after exposure to different temperatures for a period of 45 d.F Dámaso Fernández-Ginés Sergio García-Mu?oz Héctor Mateo-Carrasco Miguel ángel Rincón-Cervera Manuel Corti?as-Sáenz José Antonio Morales-Molina Carmen Fernández-Sánchez Juan Miguel Expósito-López Ignacio Rodríguez-García 2016World Journal of Pharmacology2016,5,3:0
