The changes in the physicochemical properties (solubility, Ca2+ -ATPase activity, total and reactive sulfhydryl content, surface hydrophobicity [S0 -ANS]), and structure of MPS and MS were investigated in the present work. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis revealed that there were degradation and aggregation of MPS and MS caused by irradiation, and the disappearance of myosin heavy chains (MHC) irradiated by EB was earlier than that of irradiated by γ-ray. As compared with MPS, the extracted MS was more easily destroyed. With the increase of irradiation dose, the particle size, solubility, Ca2+ -ATPase activity, and SH content of MPS and MS decreased (p less then .05), while the S0 -ANS first increased and then decreased. Two-way analysis of variance results suggested that the degree of protein denaturation depends on the irradiation mode and dose. Compared with γ-ray irradiation, the EB irradiation had a greater impact on the physicochemical properties of MPS and MS.The benefit of continuous infusion neuromuscular blockade concurrently with venovenous (VV) extracorporeal membrane oxygenation (ECMO) in patients with acute respiratory distress syndrome who are receiving mechanical ventilation remains unclear. Adult patients with severe acute respiratory distress syndrome requiring VV ECMO were analyzed in 2 groups continuous infusion neuromuscular blockade with cisatracurium vs no neuromuscular blockade. Similar mechanical ventilation strategies were used. The primary end point was duration of VV ECMO. This single-center, retrospective observational cohort included a total of 47 patients, 28 of whom received continuous infusion cisatracurium and 19 patients who did not receive neuromuscular blockade. There was no diffe
