The application discloses a pharmaceutical composition for treating cardiovascular diseases and a preparation method and application thereof. The composition comprises perindopril or a pharmaceutically acceptable salt thereof, amlodipine or a pharmaceutically acceptable salt thereof and amino-modified silicon dioxide. The amino-modified silicon dioxide is prepared by modifying the surface of silicon dioxide by using 3-aminopropyl triethoxysilane as a coupling agent. The composition of the application can be stored stably without adding an antioxidant, and especially, can avoid or reduce impurities generated by oxidative degradation of perindopril and amlodipine, and improves the safety of the medicine.

The utility model relates to fire extinguisher support technical field, especially for an improved fire extinguisher support, including the bucket -shaped support, the bucket -shaped support is provided with two groups symmetry, the top edge of bucket -shaped support is arranged as cambered surface, cambered surface design can avoid the hand of personnel being scratched by the top edge of bucket -shaped support in the use process, through setting up the bucket -shaped support with horizontal support flat iron can provide protection to the bottom one side of fire extinguisher main part through the bucket -shaped support when the fire extinguisher main part is placed in the inside of bucket -shaped support, avoid water splashing to the surface of the bottom one side of fire extinguisher main part, when the fire extinguisher main part is placed in the inside of bucket -shaped support, it will place in the top of horizontal support flat iron, thereby make the bottom of fire extinguisher main part and ground form certain gap, thereby avoided or reduced the condensate of fire extinguisher bottom when ground is damp, avoided the rust of fire extinguisher bottom because of being soaked and caused, thereby led to the problem of fire extinguisher damage, improved the service life of fire extinguisher.
