The qi-regulating and blood-activating preparation is prepared from fructus cinnamoii, blumea balsamifera, ligusticum wallichii and allium macrostemon, and the preparation can be a dripping pill, a capsule, a tablet, a granule or a solution. Experiments show that the qi-regulating and blood-activating preparation can effectively treat heart failure, especially heart failure after myocardial infarction, and can reduce the infarction area of the heart, improve inflammatory lesion of the heart and improve myocardial fibrosis; the proliferation of myocardial cells induced by blood oxygen deprivation can be promoted, and the apoptosis of the myocardial cells can be improved. The use is convenient;

The utility model discloses a self-circulation filtering table top pipe fitting-free fish tank, which comprises a transparent main tank and a bottom filtering tank which is arranged below the main tank and is fixed with the main tank into a whole, a filtering area and a water purifying area communicated with the bottom of the filtering area are arranged in the bottom filtering tank, a filtering device is arranged in the filtering area, and the water purifying area is communicated with the bottom of the filtering area. A sewer pipe with the upper end extending to the bottom of the main cylinder to communicate the filtering area with the main cylinder is arranged in the filtering area, the lower end of the sewer pipe is located above the filtering device, and a water feeding pipe with the upper end extending to the bottom of the main cylinder to communicate the water purifying area with the main cylinder is arranged in the water purifying area; a water pump which is connected with the lower end of the water feeding pipe and is used for conveying water from the water purification area to the main cylinder through the water feeding pipe is arranged in the water purification area; and a floating ball valve which is positioned in the water purification area and is used for controlling the water outlet pipe to be opened or closed according to the water level of the water purification area is arranged on the water discharging pipe. Compared with the prior art, the fish tank has the advantages that people do not need to worry about fish death caused by oxygen deficit and poisoning due to the fact that water in the main tank is evaporated and cannot be filtered and purified when going out for a long time.

This invention provides a drug delivery system and its application based on brain microvascular endothelial cells, comprising stimulated brain microvascular endothelial cells, wherein the stimulation is performed by culturing in a culture system containing supernatant of brain microvascular endothelial cells cultured under glucose and oxygen deprivation. This invention solves the problems of targeting and timeliness in treating blood-brain barrier damage after ischemic stroke under current technologies. It can regulate the BBB while supporting its function and structure, maintaining and repairing BBB function after reperfusion, thus improving the prognosis of stroke treatment. The cell preparations in this invention are widely available and easily obtained, and can rapidly repair the blood-brain barrier. Furthermore, the cell preparations in this invention can target ischemic brain sites and can be administered via simple intravenous injection, facilitating clinical operation.
