The invention discloses a spherical scaffold used in the stomach. The spherical scaffold used in the stomach is made of metal alloy wires comprises an upper circle (1), a lower circle (4), a bone longitude line (2) and a bone latitude line (3), wherein the upper circle is opposite to the lower circle, the bone longitude lines are spaced in an arc shape, one end of each bone longitude line is connected with the upper circle, and the other end is connected with the lower circle; the bone latitude lines and the bone latitude lines are interwoven spirally at equal intervals to form a grid; the spherical scaffold used in the stomach is in a net shape in the relaxation state and in a cylindrical pipe shape in the contraction state. The spherical scaffold used in the stomach has the smooth surface, has characteristics of softness and elasticity and can perform passive peristalsis in the gastric cavity along with stomach peristalsis, besides, the spherical scaffold is changeable in the stomach due to the wet and smooth internal environment secreted by gastric mucosa, cannot be inlaid in the gastric cavity or embedded by the gastric mucosa, can be taken out conveniently at any time under the assistance of a gastroscope and can be reused, and bad reactions and obesity bounce on a dieter during usage can be effectively prevented.

A Chinese medicine in the form of honeyed pill for dropping drug is prepared from 39 Chinese-medicinal materials including notoginseng, astragalus root, corydalis tuber, eagle wood, ginseng, etc through classifying, pulverizing, sieving, mixing, adding honey and distilled water, stirring and pilling. Its advantages are high and stable curative effect, short course of treatment, low recurrence rate and low toxic by-effect.

The invention discloses a traditional Chinese drug detoxification Jiangsangao capsule, which is made of 39 traditional Chinese medicines such as Panax notoginseng, Astragalus root, Xuanhu, agarwood and ginseng, which are washed, dried, pulverized and mixed evenly, and packed into a capsule to make a capsule. It has the advantages of stable curative effect, short course of treatment, less toxic and side effects, and low relapse rate. It can also enhance the immune function of patients with "three highs" (ie, high blood pressure, high blood fat, and high blood sugar) of cardiovascular system diseases, and achieve the effect of rehabilitation treatment.

The present invention provides rGO-LiOH micro-spring / wood composite electrode material and its preparation method and application. The method includes step 1, ultrasonically pulverizing lithium carbonate, graphene oxide and deionized water and then freeze-drying to obtain LiCO 3 and GO airgel; step 2, the LiCO 3 After the moisture in the airgel with GO is removed, heat it at 1000-1200°C for 2-5 hours in nitrogen or inert gas to obtain rGO-LiOH micro-springs; step 3, blow the rGO-LiOH micro-springs into the carbonized In the pores of lignin wood, an electrode material with three-dimensional high specific capacitance, high elasticity, high porosity and high specific surface area is obtained. The electrode material can be further assembled into elastic capacitors or wearable capacitors, which can drive any electronic device within the range of the capacitor.

The invention belongs to the technical field of oilfield production, and in particular relates to a temporary plugging agent for fracturing and a preparation method thereof. The components and parts by weight are: 38 parts of hydroxypropyl cellulose and 15 parts of polyvinyl butyral , 16.5 parts of zinc oxide, 27 parts of urea-formaldehyde resin, 6 parts of hexamethylene tetraammonium, 14 parts of calcium hypochlorite. Mix hydroxypropyl cellulose, polyvinyl butyral, zinc oxide, urea-formaldehyde resin, hexamethylenetetraammonium and calcium hypochlorite at room temperature at 25°C, and then add the mixture slowly under stirring After stirring in water for 30 minutes, the temporary plugging agent for fracturing can be obtained. This temporary plugging agent can withstand a pressure difference of 40.6MPa after waiting for 2 hours in the wellbore at 60°C. After the gel is broken, the viscosity of the gel-breaking fluid is less than 5mPa·S, and all of it can be discharged to the ground through the flowback process.

The invention discloses a preparation method of a curved-surface fly's-eye lens array. According to the advantages of big deformation behavior of a flexible film mixed up with ferromagnetic grains in a magnetic field environment, and deflection controlled by the magnetic field, the preparation method of the curved-surface fly's-eye lens array through the induction of the magnetic field is proposed; from the manufacturing technique, the preparation method is featured by fast and simple operation, low cost and small dimension of a single lens, and so on.

The invention discloses a tripterine nanostructure lipid carrier modified by lentiviral vector and preparation method and application thereof, wherein teh tripterine nanostructure lipid carrier modified by the lentiviral vector consists of tripterine and a lipid carrier, various components comprise 1 part by weight of tripterine, 0.5 to 10 parts by weight of lentiviral vector, 5 to 100 parts by weight of lipid blends, 0.5 to 20 parts by weight of emulsifier and 5 to 100 parts by weight of stabilizer. The tripterine nanostructure lipid carrier modified by the lentiviral vector can increase nanoparticles encapsulating rate to 78-90%. The tripterine nanostructure lipid carrier modified by the lentiviral vector uses oral administration, thereby promoting absorbing of the tripterine in a body, improving bioavailability, reducing administration dosage, reducing accumulation of the tripterine in the body at last, reducing toxic reaction by combining sustained release of a nanostructure lipid carrier, and improving clinical therapeutic effect of the tripterine at last.
