The invention discloses a suppository for treating haemorrhoids, and belongs to external traditional Chinese medicines for treating haemorrhoids. The suppository is prepared from golden cypress, scutellaria baicalensis, gallnuts and radix sophorae flavescentis by the following steps: 1) adding the golden cypress into ethanol 8 times by weight, carrying out reflux extraction three times, and concentrating the filtrate to obtain golden cypress concentrated liquor; 2) decocting the scutellaria baicalensis for 10 minutes by boiled water 14 times by weight of residual three medicinal materials, adding the gallnuts and the radix sophorae flavescentis and decocting for 2 hours, and filtering; 3) then, adding water 12 times by weight to decoct twice, combining the filtrates obtained by three times, and concentrating to obtain a fluid extract with relative density of 1.10-1.15; 4) adding ethanol into the fluid extract, standing for 18 hours, filtering and concentrating to obtain concentrated extracting liquor; 5) combining the concentrated extracting liquor and the golden cypress concentrated liquor, vacuum-drying and crushing to obtain medical powder; and 6) after uniformly mixing the medical powder with a matrix in a weight ratio of 4:6, carrying out injection moulding and cooling to obtain the suppository. The suppository disclosed by the invention has a good curative effect on hemorrhage, swelling, pains, constipation and the like caused by internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, and is an external medicine for treating haemorrhoids.

The invention discloses a drug applying plant spearmint extract in curing habitual constipation in the pharmaceutical industry and a preparation method of the drug and the extract. The preparation method of the plant Mentha Spicata.L extract is as follows: adding water into dry Mentha Spicata.L for soaking, heating and boiling for about 2 hours, collecting filtrate, adding water once again and boiling, collecting filtrate, merging the two filtrates, concentrating the merged filtrates to extract with a relative density, drying, crushing, and respectively preparing into particle electuaries, capsules and slow release capsules. The preparation method for particle electuaries is implemented as follows: pelletizing the plant Mentha Spicata.L extract by ethanol, drying, straightening pellets and performing subpackage to obtain the finished product particle electuaries. The preparation method for capsules is as follows: drying the plant Mentha Spicata.L extract, pelletizing and encapsulating into the capsules. The preparation method for slow release capsules is as follows: adding proper amounts of starch and ethanol into the plant Mentha Spicata.L extract, preparing the mixture into dry particles, coating the dry particles by enteric acrylic resins, and encapsulating. In the invention, the effective components of the whole dry spearmint plant are extracted and applied to curing habitual constipation, thus the Mentha Spicata.L serves as a single pure plant to solve the habitual constipation independently in clinics, and has good effect for curing the habitual constipation in clinics.

The invention provides a preparation method of capsules capable of activating blood and stopping pains. The preparation method comprises the following steps: taking six types of medicinal materials including 22g of Chinese angelica, 44g of radix notoginseng, 44g of vinegar processed frankincense, 11g of borneol, 111g of ground beetles and 67g of calcined pyrite; adding water with the weight which is 10 times as much as that of the medicinal materials; immersing for 0.5h and decocting for 1 hour; filtering and adding water with the weight which is 8 times as much as that of the medicinal materials into medicine residues; decocting for 1 hour and filtering medicine liquid; combining decocted liquid of the two times and concentrating until the relative density is 1.05 at 60 DEG C; adding ethanol until the volume percent of alcohol content reaches 75 percent; stirring, standing and filtering; concentrating filtrate until the relative density is 1.25 at 65 DEG C; recycling the ethanol to obtain a concentrated solution; carrying out super-critical extraction to obtain super-critical extract; continually concentrating and drying the concentrated solution; granulating and filling the capsules to obtain the capsules capable of activating blood and stopping pains. By adopting specific concentration and drying equipment, the prepared capsules capable of activating blood and stopping pains have high content of ferulic acid and can be applied to preparation of medicines for inhibiting Vero-E6 cell proliferation of African green monkey kidneys.

The invention discloses a method for preparing a sandy soil foundation model in a sandy soil foundation model test. The operation is as follows: A. Determination of the diameter of the sand outlet hole: according to the relative compactness D of the sandy soil foundation model to be prepared _r , Calculate the diameter of the sand hole d(mm) of the sand head, d=22.41‑0.25D _r , where d≥4D _max ,D _max Be the maximum grain size of the sand; B, the opening of the sand head: set the sand hole at the bottom of the sand head with the aperture as the sand hole diameter d determined in the A step; C, the preparation of the model: the B step made The top of the sand outlet is connected to the sand barrel through a hose. Under the condition of a drop distance of 80cm to 100cm, the sand is dripped and sprinkled to the model box directly below it through the sand outlet of the sand outlet until the sand sample in the model box reaches Just set the thickness. The prepared sand foundation model has small relative compactness error, high accuracy, and good reliability of the data obtained from the test; it can provide more reliable test data for the design and construction of engineering structures on the sand foundation, and more Good guarantee the safety of engineering structures.

The invention discloses traditional Chinese medicine bath antibacterial liquid/granules for regulating the Yang-deficiency constitution and a preparation and using method. The traditional Chinese medicine bath antibacterial liquid/granules are prepared from, by weight, 5-35 parts of rhizoma cibotii, 5-35 parts of fructus litseae, 5-35 parts of fructus cnidii, 5-35 parts of cassia twig, 5-35 partsof perilla leaves and 5-50 parts of tremella fuciformis. The preparation method comprises the steps that the tremella fuciformis is smashed into superfine tremella fuciformis powder; the other medicine materials are mixed and decocted by adding water, and then filter liquor is collected; the superfine tremella fuciformis powder is added into the filter liquor to obtain a mixture, the mixture is decocted and then concentrated into thick liquid with the relative density of 1.05-1.25, and the thick liquid is filtered to obtain the traditional Chinese medicine bath antibacterial liquid; the traditional Chinese medicine bath antibacterial liquid is further prepared to obtain the antibacterial granules. The traditional Chinese medicine bath antibacterial liquid/granules can effectively regulatethe Yang-deficiency constitution, and therefore, the aims of building the body and preventing diseases are achieved.

The invention relates to a preparation method of analytically pure zinc bromide. The method comprises the following steps: (1) hydrobromic acid is added into a reactor with a stirrer, and is heated, such that a hydrobromic acid solution is heated to 80 DEG C; under stirring, (2) zinc oxide is slowly added into hydrobromic acid; when the pH value of the reaction material is 7, zinc oxide addition is stopped; the reaction liquid is filtered, heated and concentrated under a temperature of 230-250 DEG C, wherein a relative density is controlled at 19-20 DEG Be; cooling and crystallization are carried out; and spin-drying is carried out, such that the analytically pure zinc bromide is obtained. According to the analytically pure zinc bromide preparation method, zinc oxide is subjected to a reaction with hydrobromic acid, such that zinc bromide is produced. With the method, high-purity zinc bromide can be obtained. The preparation method is simple, and the operation is easy to control.
