The invention relates to a health care composite which consists of lecithin, grape pip extract and ginkgo leaf extract. The invention consists of the lecithin, the grape pip extract and the ginkgo leaf extract together; wherein, the lecithin accounts for 10 percent to 80 percent of the total weight, the grape pip extract accounts for 1-50 percent of the total weight and ginkgo leaf extract accounts for 1-50 percent of the total weight. The invention has the advantages that: the lecithin has the functions of nourishing the brain, improving intelligence, regulating blood lipid, eliminating fatigue, improving sleep, and so on; the grape pip extract has mighty antioxidation for the human body, can reduce erythrocyte aggregation and the permeability of capillary vessel; the ginkgo leaf extract can improve cerebrovascular circulation, protect brain cells from being damaged due to ischemia, dilate the coronary artery, prevent angina and myocardial infarction, eliminate harmful oxygen free radical, promote immunity and resist aging, and so on; the composite combined by three medicines brings convenience to consumers for oral administration and integrates three efficacies into a whole, thus enhancing the curative effect of the health care product.

The invention provides a high-efficiency hemostatic material based on chitosan fiber and a preparation method thereof. In the invention, the chitosan is firstly spun to obtain the chitosan fiber substrate, and then carboxyl and catechol structures are simultaneously grafted on the chitosan fiber substrate. The hemostatic material can quickly absorb water in the blood to swell, thereby significantly improving the hemostatic rate. The introduction of the carboxyl group makes it have super liquid absorption ability, so that the platelets in the blood at the bleeding site can quickly adhere and aggregate to form a thrombus, and the hydroxyl group on the catechol group can complex with the iron ions in the blood red blood cells, causing the red blood cells to aggregate It plays a role in stabilizing blood clots, and finally achieves the effect of rapid hemostasis. The high-efficiency hemostatic material provided by the invention is especially suitable for massive bleeding.

The invention relates to a medicine for curing cerebral thrombosis and a preparation method thereof. The medicine of the invention is prepared by raw medicines with portions according to the followingweight ratio: 70-90 portions of Bupleurum chinense DC, 90-110 portions of RhizomaChuanxiong, 70-90 portions of root of red rooted salvia, 150-170 portions of radix astragali, 80-100 portions of earthworm, 50-70 portions of radix curcumae, 140-160 portions of core-removing hawthorn, 40-50 portions of radix notoginseng and 1.5-2.5 portions of borneol. The preparation method comprises that the radixnotoginseng are ground into 120 meshes of fine powder, the borneol is ground into 120 meshes of fine powder, and the Bupleurum chinense DC, the RhizomaChuanxiong, the root of red rooted salvia, the radix astragali, the earthworm, the radix curcumae and the core-removing hawthorn are cut into chips which are decocted with 1000g water for three times and each time is decocted for one hour; the rawmaterials being decocted are extracted, filtered, compressed, dried and ground into 120 meshes of fine powder, in which the radix notoginseng fine powder and the borneol fine powder are added and mixed evenly, thus obtaining the medicine through split charging into 0.5g of capsules. The medicine of the invention can promote blood circulation by removing blood stasis, warm channels and expel cold,restore consciousness and resuscitate and resist platelet aggregation; moreover, the medicine of the invention also can replenish qi to secure the exterior, clear away heat and toxic material, nourishblood and tranquilize mind and resist thrombosis; furthermore, the medicine of the invention can relieve the depressed liver, cool blood and remove stagnation and reduce erythrocyte aggregation; themedicine further can relieve muscles and warm channels, promote salivation and activate yang, dispel wind and toxicity, relieve heart and restlessness and regenerate tissues.

The invention discloses a method of analyzing a platelet aggregation function according to platelet size changes, and belongs to the field of clinical laboratory medicine. The method of analyzing the platelet aggregation function according to the platelet size changes measures the platelet size changes before after aggregation processing, and calculates the aggregation rate value of platelet according to the size changes of the platelet in a sample, and therefore the strength of the platelet aggregation function can be reflected. The method of analyzing the platelet aggregation function according to the platelet size changes also can be applied to erythrocyte aggregation rate analysis.
