And a method for making the same comprising the steps of: providing an intimate mixture of the polymeric material and any surfactant in a liquid medium: providing a fluid freezing medium at a temperature effective for rapidly freezing the liquid medium; cooling the liquid medium with the fluid freezing medium at a temperature below the freezing point of the liquid medium for a period effective to rapidly freeze the liquid medium; and freeze-drying the frozen liquid medium to form the porous bodies by removal of the liquid medium by sublimation.

The invention discloses a kit and an extraction method for rapidly extracting RNA of animal fecal microorganism. The kit mainly adopts a silicone mold adsorption column to absorb the RNA of the fecal microorganism, and then adopts a peculiar protein removing solution and a rinsing solution to wash away impurities such as proteins and the like. Compared with the conventional method for extracting the RNA of the animal fecal microorganism, the extracting method by using the kit saves plenty of time for extraction and meanwhile simplifies experimental procedure, and can extract the RNA of the animal fecal microorganism more effectively, rapidly and economically.

The invention provides a continuous fiber 3D printing device and a continuous fiber 3D printing method. The continuous fiber 3D printing device comprises a fiber roller, a gumming part and a printingpart; the gumming part is provided with a housing injected with a resin solution; a tension roller, a gumming opposite-opening roller and a traction roller are sequentially arranged in the housing; the tension roller is arranged above a liquid level of the resin solution and is used to provide dry fiber with a part of pre-tightening force by the action of frictional force; the gumming opposite-opening roller is arranged below the liquid level of the resin solution; the gumming opposite-opening roller and the tension roller form an included angle; the traction roller is arranged above the liquid level of the resin solution and is used to provide traction force; and the dry fiber enters into the gumming part through the fiber roller, is gummed by the tension roller, the gumming opposite-opening roller and the traction roller sequentially, and then is printed by the printing part. The intensity of an obtained workpiece is improved by more than 4 times compared with that of a workpiece in3D printing of existing resin, so that a foundation is laid for high-performance printing components applied to the aerospace field.

The invention discloses a low-temperature high-yield single subunit RNA (ribonucleic acid) polymerase, namely VSW3RNA polymerase, which is applied to efficient synthesizing of RNA at low temperature.The single subunit RNA polymerase is RNA polymerase expressed by a low-temperature phage VSW-3, and can be used for transcribing and synthesizing RNA by taking DNA (deoxyribonucleic acid) as a template within the temperature range of 4-30 DEG C; when the temperature is 25 DEG C, the efficiency of synthesizing RNA by the VSW3RNA polymerase is the highest, and the yield of the VSW3RNA polymerase even exceeds that of T7RP which is widely applied to RNA in-vitro transcription synthesis at present. A base sequence for coding the enzyme is shown in a sequence table SEQ ID NO. 1, an amino acid sequence of the enzyme is shown in a sequence table SEQ ID NO. 2, and a specific promoter sequence recognized by the enzyme is shown in a sequence table SEQ ID NO. 5. The VSW3RNA polymerase is found to be afirst single subunit RNA polymerase which has RNA synthesis capability comparable to or even superior to that of T7RP, and the most suitable temperature for transcribing and synthesizing RNA is 25 DEG C and is 12 DEG C lower than the transcription temperature of 37 DEG C of T7RP, thus an important enzyme tool is provided for efficiently synthesizing RNA at low temperature, and the increasing requirements of scientific research and medical markets on RNA products can be met.

The invention belongs to the technical field of medicines, and particularly relates to procaterol hydrochloride oral liquid and a preparation method thereof. The procaterol hydrochloride oral liquid is prepared from the following raw material components in percentage by mass: 0.0005 percent to 0.001 percent of procaterol hydrochloride, 0.0025 percent to 0.0075 percent of ethylparaben, 0.00125 percent to 0.00375 percent of butyl paraben, 0.01 percent to 1.0 percent of essence, 1.5 percent to 5.0 percent of a solvent, 0.05 percent to 0.4 percent of sodium benzoate, 0.1 percent to 2.0 percent of citric acid, 0.05 percent to 1.0 percent of citrate, 25 percent to 50 percent of a flavoring agent and the balance of water, wherein the total mass of the procaterol hydrochloride oral liquid is 100 percent. According to the procaterol hydrochloride oral liquid, the stability of the procaterol hydrochloride oral liquid is ensured through the synergistic effect of all the raw material components and the mass percentage content, the risk of degradation of active ingredients of procaterol hydrochloride is effectively reduced, and the stability and the curative effect of the oral liquid are improved.
