The invention discloses enterobacter cloacae for stably producing 2,3-butanediol at high yield and a method for compound mutation by using low-temperature plasma and diethyl sulfate. The enterobacter cloacae is classified and named as Enterobacter cloacae DLM and has the preservation number of CGMCC (China General Microbiological Culture Collection Center) 6053. The mutation method is characterized in that bacterium is suspended into physiological saline and pretreatment of diethyl sulfate and compound mutation of the low-temperature plasma and the diethyl sulfate are sequentially carried out. The strain can be used for producing the 2,3-butanediol by fermenting different effectively-utilized carbon sources, wherein the conversion rate of sugar is high and the concentration of the 2,3-butanediol is high; and when glucose or synanthrin is hydrolyzed into a carbon source, the concentrations of the 2,3-butanediol in a 5L fermentation tank respectively reach 125.2g / l and 120.2g / l. The mutation method used in the invention has the characteristics of simpleness and feasibility in operation, short treatment time in mutation and the like and provides a reliable method for mutation breeding of microorganisms.

The invention relates to the drug technical field and concretely provides a novel drug preparation for resisting the gout. The preparation includes the raw materials of two traditional Chinese medicines of a wormwood leaf and a plantain seed, which are mixed, dipped and boiled for obtaining a water-extract to be filtered, heated, condensed, centrifugally residue removed, freeze-dried, dissolved by normal saline, filtered by a filter membrane and finally made into the novel drug preparation for resisting the gout. The animal text shows that the novel drug preparation of the invention can very effectively reduce the oteracil potassium to induce the uric acid standard in the blood of a mouse with the hyperuricemia and greatly improve and effectively cure the mice of arthrocele and difficult action, and the novel drug is further used for resisting the human gout to take particular effect.

The invention discloses a liquid wound repairing film and a preparation method thereof. The liquid wound repairing film comprises a base solution and a film solution, wherein the base solution is a physiological saline solution of carboxymethyl chitosan (CMC); the concentration of the carboxymethyl chitosan in the base solution is 0.5-5.0 mg / mL; the film solution comprises polyvinyl butyral (PVB) and an ethanol solution; the concentration of the ethanol solution is 80-100%; and the using amount of the polyvinyl butyral is 0.5-1.7 g in every 10mL of the ethanol solution. The liquid wound repairing film has the characteristics of quickness in drying, water tightness, breathability, bacterial resistance and the like, and is high in bio-safety and accurate in therapeutic effect.

The invention discloses an automatic hematoma flushing device which is specifically used by the following steps: 1) respectively connecting an infusion tube with a balloon and a normal saline infusion bottle containing urokinase, connecting the infusion tube at the lower end with a tee joint, and respectively connecting the other two ends of the tee joint with a negative pressure drainage bottle and hematoma to be flushed; (2) respectively fixing three valves on an infusion tube, fixing a balloon, an eccentric wheel and the like together, and switching on a power supply of a control panel; in the rotating process of the eccentric wheel, continuously extruding the balloon to change the volume of the balloon, so that the pressure periodically changes; (3) by changing the opening and closing conditions of the three valves, indicating the balloon filled with the flushing fluid flushes the hematoma of the patient, after balance is achieved, carrying out negative pressure drainage and starting ratistathe next cycle when the drainage flushing fluid is almost too much. The invention has the advantages that periodic pressure is generated through rotation of the eccentric wheel, flushing liquid and hematoma are fully mixed, the hematoma is dissolved, dissolved liquid is drained out through the negative pressure drainage bottle, and therefore the purpose of removing the hematoma is achieved. As the liquid in the infusion tube inserted into the hematoma flows all the time, blood coagulation can be avoided, the infusion tube is prevented from being blocked, and drainage failure is avoided. By means of the three electronic valves, closing and opening of the infusion tube are achieved, and the purpose of control is achieved.
