The invention discloses a hematoxylin staining solution suitable for a fully automatic immunohistochemical staining instrument and a preparation method thereof, wherein the hematoxylin staining solution comprises the following components by weight: 1 to 3 parts of hematoxylin, 10 to 14 parts of potassium aluminum sulfate, 80 to 120 parts of anhydrous ethanol, 600 to 800 parts of distilled water, 0.18 to 0.22 parts of sodium iodate, 0.4 to 0.6 parts of citric acid, and an appropriate amount of pH regulator to adjust the pH of the hematoxylin staining solution to 2.1 ± 0.2. The hematoxylin staining solution of the invention has a lower concentration than conventional hematoxylin staining solution, and a lower pH value than conventional hematoxylin staining solution. After the hematoxylin staining solution is used to redye the tissue, it only needs to be rinsed with a partial alkaline detergent to ensure that the tissue cell nucleus is colored light blue, which forms a sharp contrast with the DAB color, and the tissue layer is clear, thereby improving the contrast between the hematoxylin staining solution and the DAB color developer color, and helping the pathologist to interpret the fully automatic immunohistochemical results.

The invention belongs to the technical field of medicines, and particularly relates to a ceftizoxime sodium micro-capsule, a preparation method and a ceftizoxime sodium micro-capsule preparation. The invention provides a ceftizoxime sodium micro-capsule. The ceftizoxime sodium micro-capsule comprises a capsule core and a capsule wall material wrapping the capsule core, the capsule material comprises an inner coating and an outer coating, the inner coating wraps the capsule core, and the capsule core comprises ceftizoxime sodium; the inner coating comprises carboxymethyl glucan; the outer coating comprises glyceryl monolinoleate; the mass ratio of the ceftizoxime sodium to the carboxymethyl glucan to the glyceryl monolinoleate is (1 to 3): (0.5 to 1.5): (0.5 to 1.5). The prepared ceftizoxime sodium micro-capsule is high in stability, long in storage period and good in slow release effect.

The invention provides a preparation method for extracting bamboo reed cellulose and MXene composite regenerated fibers based on oxidation-ultrasonic coupling, and belongs to the field of biomass-based functional fiber materials.The preparation method comprises the steps that after bamboo reed raw materials are cooked, the pH value of a system is adjusted, the liquid carrying rate is controlled, oxidation and ultrasonic pretreatment is conducted, the raw materials are purified, and the bamboo reed cellulose and MXene composite regenerated fibers are obtained; bamboo reed cellulose is obtained; a composite solution system is adopted for dissolving the spinning solution, and a uniform spinning solution is prepared; the preparation method comprises the following steps: uniformly dispersing MXene in a spinning solution in proportion, and preparing the bamboo reed-based MXene composite regenerated cellulose fiber by taking a buffer solution as a coagulating bath and adopting wet spinning. The invention solves the problems of high energy consumption, large reagent dosage, low yield and easy damage of cellulose structure in the existing bamboo reed cellulose extraction, and the problems of insufficient cellulose purity, poor MXene dispersity, poor interfacial compatibility, poor spinning solution stability and forming effect and the like in the MXene composite regenerated fiber preparation.

The application discloses a kind of stable indometacin tablets and its preparation process, belong to pharmaceutical preparation technical field.The tablet is composed of indometacin, hydroxypropyl beta-cyclodextrin, soybean phospholipid, composite stabilizer, binder and lubricant, and the composite stabilizer is compounded by succinylated c14-c18 alkyl sulfonate sodium, N-ethyl-L-glutamine and maltodextrin according to specific mass ratio.Preparation process includes liposome inclusion compound preparation, mixing granulation, drying whole particle, total mixing and tabletting.The application realizes the preparation of high drug loading design, and the composite stabilizer forms a multilayer coating protection system with hydroxypropyl beta-cyclodextrin and soybean phospholipid, which synergistically improves the dissolution performance and stability of the preparation, makes the dissolution rate of the preparation fast, and the content of the main component decreases little during long-term storage, solves the problems of low drug loading, poor stability and dissolution of existing indometacin tablets.
