The invention discloses a traditional Chinese medicine combination for the treatment of gynecological hyperlipemia and a preparation method thereof. 60 portions to 120 portions of glossy privet fruit and 25 portions to 75 portions of charred pollen typhae are comminuted into fine powder of 50 meshes to 120 meshes, and set aside; 100 portions to 180 portions of angelica, 60 portions to 120 potionsof motherwort herb, 80 portions to 120 portions of Yerbadetajo Herb, 80 portions to 150 portions of radix pseudoginseng, 25 portions to 75 portions of radices salviae miltiorrhizae, 80 portions to 120 portions of hairy vein agrimony, 25 portions to 75 portions of rhizoma cyperi charcoal, 25 portions to 75 portions of carbonized biota tops, 25 portions to 75 portions of radix codonopsis pilosulae,25 portions to 75 portions of atractylodes macrocephala are added with 6 times to 20 times of water and then decocted for three times, namely 2 hours, 1.5 hours and 1 hour in sequence. Decoction solution is integrated and filtered; the filtrate is reserved; the filtrate is concentrated; fine powder of glossy privet fruit and charred pollen typhae are added into the concentrated filtrate, mixed evenly, dried and comminuted to fine powder of 60 meshes to 100 meshes, and sieving is carried out to obtain the combination. The drug has obvious treatment effects on symptoms of hypermenorrhea, large menstrual volume presented due to bradymenorrhea, prolonged menstruation, abnormal color quality in menstrual period, pain in the lower abdomen, lumbosacral aching, listlessness and the like, and is characterized by faster onset, high efficacy, few side effects and the like, being a comparatively ideal drug for the treatment of gynecological hyperlipemia.

A preparation method of the invented quick-soluble scaffold for anastomosis of blood vessel includes the following steps: firstly, preparing double-distilled water solution by using dissolvable polymer, heating the above-mentioned solution, quickly stirring and adding physiological salt powder to form ropy compound, using mould to extrude or draw the said compound to make it into claviform or hollow tube which is identical to vassel of human body in diameter so as to obtain the invented soluble scaffold material. This blood vessel scaffold possesses micrometer level porosity in structure, after it is compounded with physiological salt crystal, its mechanical strength is increased, in the course of application, it features proper dissolving time, smooth surface, good elasticity and does not damage endangium, and it is non-toxic, and has no residual. It is quick in anastomosis speed, simple and easy to implement.

The invention discloses an oil-proof sustained-release solid foaming drainage agent used for gas wells, and a preparation method and applications thereof. The oil-proof sustained-release solid foaming drainage agent is mainly used for solving problems of conventional solid foaming drainage agents that high local concentration and waste are caused because of high dissolving speed, and preferable application is different to realize when gas well output water is high in gas condensate content, high in mineralization degree, and high in temperature. The dissolving time of the oil-proof sustained-release solid foaming drainage agent at 90 DEG C formation water condition is longer than 72h, and agent effect lasting time is long; the oil-proof sustained-release solid foaming drainage agent is capable of resisting gas condensate of 50% or higher, temperature of 120 DEG C or higher, and mineralization degree of 250000ppm; the foaming power is equal to or larger than 140mm; foam stabilizing time is long; and compatibility with agents such as methyl alcohol, corrosion inhibitors, and scale inhibitors is high. The preparation method is simple; no environment pollution is caused; no chemical reaction of products with gas and liquid ingredients is caused; equipment or pipeline corrosion is not caused; the prominent problems of gas wells are solved; and the oil-proof sustained-release solid foaming drainage agent is suitable for a plurality of water-producing gas wells.
