The invention discloses a dumbbell high-rise escape device, which consists of two speed reducers fixed at two ends of a central shaft, wherein each speed reducer comprises a dumbbell metal shell, a centrifugal speed reducing device with a steel ball, a planet wheel automatic speed regulating device, a shell with a safety belt accommodating groove, a steel wire rope winding device with a unilateral bearing and an emergency brake device. The dumbbell high-rise escape device serves as a dumbbell for a user to do indoor fitness exercises at ordinary times; and when a danger happens in a high-rise, the user takes out a safety belt in the dumbbell, carries the dumbbell on the back, takes out a rope and hangs the rope at a firm and reliable position, and can smoothly escape from the danger through a window.

The invention discloses an axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder. The axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder consists of a rotor, a stator and a shell, wherein the rotor consists of a transmission shaft and an impeller; the impeller is provided a spoke disc hub, first rotor blades and second rotor blades; the first rotor blades and the second rotor blades are uniformly arranged around the periphery of the transmission shaft and form an acute angle with the radial direction of the spoke disc hub; the first rotor blades are located on one side of a disc surface of a spoke disc, and the second rotor blades are located on the other side of the disc surface of the spoke disc; the stator consists of bearing end cover blades and liquid-feeding end cover blades; the bearing end cover blades and the liquid-feeding end cover blades are uniformly arranged around the periphery of an annual working cavity and form an acute angle with the radial direction; the bearing end cover blades are fixed on axial positions, which right face to the first rotor blades, of a bearing end cover; and the liquid-feeding end cover blades are fixed on axial positions, which right face to the second rotor blades, of a liquid-feeding end cover; and the oblique directions of the rotor blades and the stator blades are opposite to each other in the radial direction. By adopting the axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder, retarding and braking performance and effect are improved, and meanwhile, the axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder has better manufacturability.

The invention discloses an SDN resource distribution method based on a two-sided market multihoming structure. The SDN resource distribution method based on the two-sided market multihoming structure comprises the steps that firstly, an SDN resource distribution frame is divided into a customer layer, a control layer and a retailer layer; secondly, after the customer layer receives application requests of different users, summarizes the application requests into a request information list and transmits the request information list to the control layer through a northbound interface; thirdly, the retailer layer transmits resource information to the control layer in real time through a southbound interface; fourthly, the control layer comprises a plurality of independent control platforms, each control platform receives the resource information from the retailer layer and sends the resource information and expense information of the control platforms to the customer layer, and the users in the customer layer carry out selection from the multiple control platforms according to the self needs; fifthly, each customer requires needed resources from the multiple control platforms, and carries out selection according to a resource cost-performance ratio provided by each control platform by using a resource combination strategy. The SDN resource distribution method based on the two-sided market multihoming structure meets the requirements for tasks of users, makes full use of network resources, and improves the reliability of the network.

The invention discloses a device for accurately measuring vehicle wheel slip ratio with an aim to overcome the shortcomings that an existing wheel speed measuring device and a vehicle speed sensor cannot accurately measure vehicle wheel speed and wheel hub speed and solve the problem about the lack of a device for directly measuring the vehicle wheel slip ratio. The device comprises a telescopic adjusting mechanism (1), a sensor acquisition processing unit (2), a sensor rotating component (3) and a wheel connecting component (4). The sensor rotating component (3) comprises a rotating shaft (14) and a connecting disc (15); the rotating shaft (14) and the bottom surface of the connecting disc (15) are integrally connected, the lower end of the rotating shaft (14) is rotatably connected with the bottom plate of a device shell (19) in the sensor acquisition processing unit (2), the wheel connecting component (4) is connectively mounted on the connecting disc (15) in a threaded manner, and the right end of a screw D (13) in the telescopic adjusting mechanism (1) is connected with the left side of the device shell (19) in the sensor acquisition processing unit (2) in a welded manner.

Pre-cationic / cationic liposomal curcumin preparation for interventional treatment of liver cancer and preparation method thereof The present invention relates to a cationic / pre-cationic liposomal curcumin preparation for interventional treatment of liver cancer and a preparation method thereof. It is characterized in that, the medicine in the preparation is made from the following components: curcumin 1mg, egg yolk lecithin 3.0g, cholesterol 1.0g, octadecylamine 0.2g / [2-[[4-[(carboxymethyl)disulfide ]-1-iminobutyl]amino]ethyl]cholesteryl carbamate (CHETA) 0.05g, vitamin E 0.3g, pH 6.6 phosphate buffered saline solution 20mL. Preparation method: take egg yolk lecithin, cholesterol, octadecylamine / CHETA and vitamin E in a pear-shaped bottle, add 10 mL of ether, shake, and then add 5 mL of curcumin-containing absolute ethanol solution, and put it on a rotary evaporator at 35°C Evaporate to dryness to form a film, then add 20 mL of phosphate buffered saline solution with a pH value of 6.6, rotate for 20 minutes to dissolve the film, leave it for 3 hours to fully hydrate, sonicate for 3 minutes, and pass through a 0.22 μm filter membrane to obtain cationic / precationic liposomal curcumin . The two preparations are used to treat liver cancer through interventional administration, and have higher therapeutic effects and lower side effects on various stages of liver cancer.

The invention relates to luteolin-glycyrrhizic acid conjugated bovine serum albumin drug-loaded nanoparticles and a preparation and an application thereof. The luteolin-glycyrrhizic acid conjugated bovine serum albumin drug-loaded nanoparticles are a glycyrrhizic acid conjugated bovine serum albumin drug-loaded nanoparticles system through chemical modification of bovine serum albumin by glycyrrhizic acid, and then luteolin is coated in the glycyrrhizic acid conjugated bovine serum albumin drug-loaded nanoparticles system; wherein the glycyrrhizic acid conjugated bovine serum albumin drug-loaded nanoparticles having liver-targeting are taken as a carrier, and luteolin is taken as an anti-liver cancer bulk drug. The nanoparticles can improve the solubility, stability and targeting performance of luteolin and the drug-loaded nanoparticles to improve their bioavailability and anti-liver cancer efficacy. The encapsulation rate of the nanoparticles is increased to 30.33%. On an in-vitro cellular level, compared with GL-BSA-Lut-NPs by Lut, the drug-loaded nanoparticles have significantly increased water solubility, absorption, anti-tumor efficacy and the like.
