The present invention belongs to the field of pharmaceutical technology and clinical pharmacy, relates to a cyclopeptide containing arginine-glycine-aspartic acid (RGD) sequence and its active liposome targeting, its preparation and application. The described cyclopeptide structure meets the requirements as ligand, and is cyclized by amido bond, its spatial conformation is stable, and is not easily degraded, its one end contains active sulphydryl group, and is convenient for modifying artificially-synthetic function peptide, its molecular weight is small, so that it is not easy to result in immune reaction, and can be used as ligand, and can be combined with hepatic stellate cell (HSC) surface integrator acceptor to construct active liposome targeting and implement target therapy for experimental hepatic fibroid cell. Said invention can obtain good therapeutic effect for curing hepatitis fibrosis.

The invention discloses an aquiculture-used preparation and its preparing method, where its components in weight ratio: zeolite 70-80 kg, meaical stone 0.5-2 kg, CuSO4 0.5-2 kg, and Ca2O2 0.5-2 kg, and its preparing method: adding them to a blender to mechanically blend to make it. It has a synthetic function, such as absorbing harmful matters in the breeding water body, like amino nitrogen and sulfureted hydrogen, increasing the content of dissolved oxygen, sterilizing, increasing the content of trace elements, etc, and a synthetic effect, such as obvious abilities to improve and optimize ecological environment of breeding, promote the growth of bred living beings, and inhibit bacteria and prevent diseases, etc.

The invention discloses a dynamic and static mechanics comprehensive test bench, which relates to mechanics experimental equipment. Nowadays the mechanics test bench in the market has the disadvantages of single function, inconvenient operation, big size of the equipment and high price. A pure beam bending device, a composite beam bending device, a cylinder crankling device, a dynamic beam device, an equal strengthen beam device, a stretching and compressing device and a sinker rod are arranged on a main bench frame; the pure beam bending device, the composite beam bending device, the equal strengthen beam device, the cylinder crankling device and the stretching and compressing device respectively adopt a hand operated helical wheel to load, a sensor to measure the power, and transfer a load through a combined type lever power transmission system; the dynamic beam device uses a motor with an eccentric wheel to vibrate hardly; an interface board which is connected with the lead wire ofa strain meter is arranged on the bench surface. The invention has the functions of combining and arranging various experiments of the basic mechanics and skill training of various basic experiments.The invention has the advantages that the comprehensive function is powerful, the cost performance ratio is high, the structure is compact, and the operation is convenient.

The invention disclose a multi-wavelength fiber laser with miniature resonant cavity structures and relates to the field with requirements for high quality of optical-frequency bandwidth and the requirement of ouputting multiple wave lengths. The multi-wavelength fiber laser is used for solving the following technical problems: the structure of a fiber laser with multi-wavelength laser output is complicated, the output of high-quality multi-wavelength laser is not continuous, and the system is unstable and has high cost. The multi-wavelength fiber laser strcuturaly comprises an optical fiber formed by a fiber core (1) and a cladding (2), fiber bragg gratings (3), a miniature resonant cavity (4) in the optical fiber and a pumping source (5), and is characterized in that for the manufactureof the miniature resonant cavities, an ultraviolet laser or a femtosecond laser are adopted for exposing the optical fiber, so that the refractive index of the exposed part is higher than that of a peripheral medium, thus a plurality of miniature resonant cavity structures are generated; and each miniature resonant cavity resonates with laser with a specific wave length, and the output of multiple wavelengths can be realized by dint of the synthetic function of the plurality of miniature resonant cavities. The multi-wavelength fiber laser provided by the invention is mainly applied in fiber-optical communication.

The invention discloses a body surface negative pressure treatment device, comprising a main jar having one end opened. The main jar comprises an outer wall barrel and an outer top wall board. An inner circular barrel is disposed in the main jar. One end of the inner circular barrel is hermetically connected with the outer top wall board, and the other end of the inner circular barrel is provided with an opening. The open end of the main jar is provided with an outer seal ring. The open end of the inner circular barrel is provided with an inner seal ring. The interior space of the inner circular barrel is an inner jar cavity. Space between the inner circular barrel and the main jar is an outer jar cavity. The main jar is provided with an inner exhaust pipe and an outer exhaust pipe, the other end of the inner exhaust pipe and the other end of the outer exhaust pipe are provided with suction pump connectors, and both the inner exhaust pipe and the outer exhaust pipe are provided with exhaust one-way valves inside. The body surface negative pressure treatment device has the advantages that when a part to be cupped has constraints such as skin rupture, the damaged part of the this skin can be avoided reasonably, and cupping is done quickly and smoothly; the device also has a function of automatic drug delivery and allows 'sequential drug delivery', also has the effect of 'pneumatic massage', and has good utilization of medicinal powders, good application effect and good comprehensive functions.
