The invention provides a traditional Chinese medicine for treating vulvar leukoplakia and a preparation method thereof and belongs to the field of traditional Chinese medicine preparation techniques. The traditional Chinese medicine is prepared by using natural Chinese herbal medicines as raw material. The traditional Chinese medicine is characterized by comprising 30g of sophora flavescens, 30g of common cnidium fruit, 30g of rhizoma atractylodis, 20g of belvedere fruit, 20g of folium isatidis, 20g of astragalus membranaceus, 20g of blackberrylily rhizome, 20g of angelica, 20g of salvia miltiorrhiza, and 20g of schizonepeta. The preparation method includes: well mixing the Chinese herbal medicines according to a weight ratio, grinding into powder of 1-100 micrometers and packing with 10g per bag. Application of the traditional Chinese medicine includes: taking 10g to put into a cup, soaking with boiled water for 10 minutes, pouring into a basin, adding 1500ml warm water at 35-40 DEG C, hip bathing for 10-15 minutes, wetting gauze with the medicine for partial hot applying for 10-15 minutes, and slowly rubbing. The traditional Chinese medicine is applied 1-2 times a day for four weeks as a treatment course. Two treatment courses are needed to treat the vulvar leukoplakia. The traditional Chinese medicine for treating vulvar leukoplakia has the functions of clearing heat and itching relieving, promoting blood circulation to remove blood stasis and antisepsis and anti-inflammation; is convenient to prepare and use, lasting in medicine effect, free of side effects; and has rich raw material source, and is ideal therapeutic for treating vulvar leukoplakia.

The present invention relates to a method for preparing a new type of cement clinker, comprising the following steps: S01 obtaining raw materials, the raw materials comprising dolomite, clay and a mineralizer; S02 grinding and mixing the raw materials to obtain a mixture one; S03 adding The mixture is put into a calcining device for calcination at 800-1200° C. and kept at a temperature of 1-3 hours; S04 is cooled and ground after the calcination is completed to prepare. The cement clinker mainly contains MgO minerals with low exothermic C2S and expansion effect, and the micro-expansion generated after hydration makes up for the shrinkage of the cement.

The invention discloses a kumquat extract, a preparation method and application thereof. Kumquat extract is a kind of pure natural substance extracted from kumquat fruit. The present invention obtains the kumquat extract by ethanol reflux extraction, utilizes GC-MS to measure the main active components and content in the kumquat extract, and then proves that the kumquat extract and its active components can Significantly reduce vasoconstrictive blood pressure, regulate vasodilator factors such as angiotensin II, and at the same time reduce target organ damage caused by high blood pressure; through cell experiments, it has been proved that it can regulate the viability of HUVEC cells induced by angiotensin II. Therefore, kumquat extract has a good preventive effect on renal hypertension.

The present invention discloses a method for preparing the nano-crystalline cellulose of a flexible screen matrix material. According to the preparation method, the bagasse unbleached pulp and the chitosan are adopted as raw materials. The bagasse unbleached pulp is dissolved and dispersed in water to prepare a suspension liquid. A mixed acid is then added in the suspension liquid. After the reaction process, a high-crystallinity suspension liquid is prepared. After the centrifugation process, solid matters are washed, and then are processed by a high-pressure ultrasonic homogenizer to obtain a nano-crystalline cellulose crystal suspension slurry. The potassium periodate is added into the suspension slurry for oxidation treatment to obtain a modified nano-crystalline cellulose suspension slurry. The chitosan material is treated with acetic acid at a low temperature to prepare a chitosan saturated solution. After the ultrasonic atomization freezing treatment, the nano-scale chitosan is prepared. The nano-scale chitosan and the modified nano-crystalline cellulose suspension slurry are subjected to the mixed crosslinking treatment to prepare the composite nano-crystalline cellulose. The two materials of the method, namely the bagasse unbleached pulp and the chitosan, are abundant, easy to obtain and good in biodegradability. Therefore, the environmental protection and the waste treatment are facilitated. The prepared composite nano-crystalline cellulose can be used for manufacturing the flexible screen matrix material.

The invention relates to an auxiliary cementing material as well as a preparation method and application thereof. The preparation method of the auxiliary cementing material comprises the following steps: (1) crushing dolomite; (2) piling the crushed dolomite, and performing calcining in calcining equipment, and keeping the temperature, wherein the calcining temperature is 800-900 DEG C, and the temperature keeping time is 1-2 hours; and (3) cooling a calcining product, and grinding into powder. The auxiliary cementing material can replace 10-30% of cement in an equal mass in mortar or concrete preparation. By adopting the auxiliary cementing material, the amount of cement is greatly reduced, and great economic effects are achieved.
