The health beverage has the health functions of inhibiting platelet aggregation, reducing packed cell volume, lowering blood viscosity, etc and thus can lower theatherosclerosis incidence rate, and prevent hypertension, myocardial infarction, etc.

The invention discloses an agarose gel electrophoresis method for detecting microsatellite DNA by using multiple sample application and double-layer electrophoresis, and relates to an agarose gel electrophoresis method for detecting the microsatellite DNA, to solve the problems that agarose powdered sugar and electrophoretic buffer solution are greatly wasted and the EB (Electron Beam) is low in utilization rate during the conventional microsatellite DNA electrophoresis detection. The method comprises the following steps of: putting two pieces of sepharose gel of the same areas on two up and down layers in parallel; carrying out sample application and electrophoresis on the lower layer and the upper layer in sequence till detected amplification products reach the bottom of the gel, stopping the electrophoresis; and subsequently carrying out gel imaging detection. By utilizing the method, the utilization rate of the sepharose gel and the electrophoresis buffer solution is greatly improved, and the labor and the cost are saved; compared with one-time sample application, no gel needs to be reprepared, one piece of 10-cm gel can be repeated for sample application for 8 times, so that the cost can be saved by more than 8 times. Therefore, rapid and efficient detection plant SSR (Solid State Relay) marker-site heritable variation is realized.

The invention discloses a Chinese medicinal composition for treating hyperlipidemia, which relates to a Chinese medicinal composition. The Chinese medicinal composition solves the common problems of more ingredients and unreliable quality caused by complicated manufacturing process in the conventional traditional Chinese medicine for reducing blood fat. The Chinese medicinal composition is prepared from tuber fleeceflower root, hawthorn, wild chrysanthemum, cassia seed, liquoric root, Chinese wolfberry, Chinese yam, oriental waterplantain rhizome, twotooth achyranthes root and red sage root. The Chinese medicinal composition for treating the hyperlipidemia is prepared by mixing traditional Chinese medicines based on traditional Chinese medicine theory; and compared with the conventional Chinese medicinal preparation for treating the hyperlipidemia, the Chinese medicinal composition has fewer traditional Chinese medicine ingredients, is scientific in mixing and prepared from widely available raw materials, does not contain excipients, is not complicatedly manufactured, can be directly taken when crushed and then prepared into capsules, is low in cost, reliable in quality and more suitable for promotion and use, and has no toxic or side effect.

A Chinese medicine for treating chronic prostatitis is prepared from 11 Chinese-medicinal materials including leech, safflower, earthworm, astragalus root, etc through proportioning, decocting, collecting decoction, filtering, vacuum concentrating, drying and granulating. Its advantage is high curative effect (86.2% of total effective rate).

The invention discloses a device and an assembly for collecting biochemical samples, belonging to the technical field of biochemical equipment, comprising a collecting and filtering mechanism, a separation and purification mechanism and a driving mechanism; There is a through drainage tube horizontally connected between the mechanism and the separation and purification mechanism; the shunt mechanism of the separation and purification mechanism includes a shunt tube using the Venturi tube principle and a resistance circuit with different resistance values ​​connected in series; the driving mechanism can be connected to the first slot and the second slot. The connecting shaft 1 and the connecting shaft 2 are respectively driven to rotate, and the electrode 1 and the electrode 2 are connected for electrophoretic separation. It solves the phenomenon that the separation sample is mixed, the sample is denatured and the capillary is easy to block due to the heating of the medium temperature caused by the electrophoretic separation of the biochemical sample. The buffer solution is recycled to reduce pollution, the separation efficiency is high, the effect is good, and the vacuum preservation of the sample can ensure the accuracy of detection. It is able to separate and collect all desired types of separated samples at one time.

The invention relates to a CH4 molecular marker DGGE identifying method for aquaculture of catfish hybrids. Southern catfishes, catfishes and hybrids of the southern catfishes and the catfishes serve as objects of study, CH4 gene sections in catfishes are selected to serve as molecular markers, the sequence difference the CH4 gene sections between the southern catfishes and the catfishes, denaturing gel gradient electrophoresis detection is performed and the southern catfishes, the catfishes and hybrids of the southern catfishes and the catfishes are identified successfully. The method has the advantages of being fast in experiment, convenient to operate, visual in identification and free from sequencing.

The invention discloses a traditional Chinese medicine used for preventing and treating cerebral thrombosis and a preparation method thereof. The traditional Chinese medicine used for preventing and treating cerebral thrombosis is prepared from the following components in mass: 6-9g of ligusticum wallichii, 10-15g of salviae miltiorrhizae, 5-10g of safflower, 8-10g of peach kernel, 5-10g of dried body of ground beetle and 8-10g of artemisia anomala. The preparation method comprises the following steps of: cleaning and soaking raw materials, boiling medicine for four times, and converging medicine juices obtained by boiling, thus the traditional Chinese medicine which is used for preventing and treating cerebral thrombosis and can be taken is obtained. According to the traditional Chinese medicine used for preventing and treating cerebral thrombosis, components are combined, functions and effects of the components are fully played, and the traditional Chinese medicine used for preventing and treating cerebral thrombosis has the effects of promoting blood circulation to remove meridian obstruction, eliminating abdominal mass and diluting thick blood, so that blood circulation is smooth, symptoms such as numbness of limbs, inconvenience in action, numbness of mouth and tongue and blurred vision are eliminated, and the traditional Chinese medicine used for preventing and treating cerebral thrombosis has a good effect for preventing and treating cerebral thrombosis.
