The results show that nanoparticles loaded with apatinib are more effective than ordinary therapeutic drugs.In order to explore the influence of nanoparticle-loaded edaravone on postoperative effects in patients with cerebral hemorrhage, a total of 120 patients who were diagnosed as cerebral hemorrhage and underwent minimally invasive hematoma removal at the designated hospital by the study from December 2014 to December 2018 were selected as research objects and divided into three groups according to the random number table method edaravone treatment (ET) group, nanoparticle-loaded edaravone treatment (NET) group, and combined treatment (CT) group with 40 patients in each group. Three groups of patients underwent routine treatments based on their conditions, including regulating blood sugar, regulating blood pressure, anti-infection, nutritional support, and managing complications, in which 25 mg edaravone injection and 100 ml saline were added for patients in NET and CT group on the basis of the routine treatment of patients in ET group. The results showed that, after 15 days of standard treatment, the 40 patientis conducive to the recovery and healing of cerebral hemorrhage. The results of this study provide a reference for further research on the influence of nanoparticle-loaded edaravone on postoperative effects in patients with cerebral hemorrhage.Nanometer zinc particles were synthesized by orthogonal test with manganese chloride, iron chloride and zinc sulfate as raw materials and NaOH as coprecipitating agent. The optimum synthesis conditions of coprecipitation method were obtained and the samples were characterized by various means. In this experiment, the SV, EF, FS, lvaws, lvawd, lvpws and lvpwd of left ventricle in mice with myocardial infarction were decreased, whil
