The invention discloses a Zn-Sr series zinc alloy as well as a preparation method and application of the Zn-Sr series zinc alloy. The zinc alloy comprises Zn and Sr, wherein the mass percent of Sr in the zinc alloy ranges from 0% to 10%, but is not equal to 0. The zinc alloy also comprises trace elements including Si, P, Li, Ag, Sn and at least one selected from rare earth elements, wherein the mass percent of the trace elements ranges from 0% to 3%, but is not equal to 0. The mechanical property of the Zn-Sr series zinc alloy disclosed by the invention meets the requirements for strength and toughness of a medical implant material, is nontoxic and favorable in tissue compatibility and blood compatibility, can be degraded by using body fluid and can be applied to preparation of medical implants; and the dissolved metal ions can be absorbed and utilized by living bodies to promote bone growth or can be discharged out of bodies through metabolism.

Four first electrodes are attached on the vicinity of a lower right end of a right clavicle, the vicinity of a lower left end of a left clavicle, the vicinity of a position on a right anterior axillary line at the level of a right lowermost rib, a the vicinity of a position on a left anterior axillary line at the level of a left lowermost rib of a living body, so as to correspond to limb leads of a standard 12-lead electrocardiogram (ECG). Two second electrodes are attached on such positions of the living body that correspond to a lead V2 and a lead V4 of chest leads of the standard 12-lead ECG. A first ECG data set corresponding to leads I and II of the standard 12-lead EGG with the first electrodes. A second ECG data set including the leads V2 and V4 with the second electrodes. An instantaneous electromotive force vector (a heart vector) is calculated based on the first and second ECG data sets, and predetermined first lead vectors of the leads I, II, V2 and V4. A third ECG data set including leads V1, V3, V5 and V6 of the chest leads is calculated based on the heart vector-and predetermined second lead vectors of the leads V1, V3, V5 and V6. A fourth EGG data set corresponding to leads III, aVR, aVL and aVF of the standard 12-lead EGG based on the first ECG data set The standard 12-lead EGG is derived based on the first to fourth ECG data sets.

An injection needle has a puncture section having a small diameter that does not give a patient pain, injury, etc. and, moreover, does not make a patient feel fear and anxiety, a base end section with a large diameter to achieve a required flow rate and strength, and a tapered section connecting the puncture section and the base end section. The injection needle and a liquid introducing instrument can eliminate pain caused by a tapered section, and excellent puncture can be made with the needle and the instrument. An injection needle (1) has a puncture section (2) provided with a needle point that can be punctured into a living body, a base end section (3) having an outer and an inner diameter larger than the puncture section (2), a tapered section (4) connecting the puncture section (2) and the base end section (3). The tapered section (4) has smaller puncture resistance than the puncture section (2), or specifically, taper angle (A) is equal to or less than 2 degrees.

The invention provides a preparation method and application of a chitosan-g-poly(epsilon-caprolactone) derivative drug-loaded nano-micelle. According to the invention, chitosan and a poly(epsilon-caprolactone) derivative provided are used for the drug-loaded nano-micelle; the preparation method is simple in process and convenient in operation; a drug with poor water solubility can be encapsulatedand conveyed, the systemic toxicity of the drug is reduced, the biocompatibility of a carrier is improved, and the curative effect of the drug is improved; and the chitosan-g-poly(epsilon-caprolactone) derivative drug-loaded nano-micelle disclosed by the invention has hydrophobic groups and hydrophilic groups which are easily degraded in a living body, can be used as a novel drug-loaded nano-micelle, has a wide substantive application scope, and has very important practical value for treating tumors.

The invention relates to the field of microbial technology and especially relates to a use of Streptomyces sioyaensis metabolite in prevention and control of Botrytis cinerea. Llex cornuta endophyte separated from the llex cornuta living bodies in Hangzhou of Zhejiang province by an endophyte microorganism separation technology is identified as Streptomyces sioyaensis by microbial taxonomy and is named as Streptomyces sioyaensis 107. The Streptomyces sioyaensis 107 is preserved in the China general microbiological culture collection center on December 12, 2012 and has a preservation number of CGMCC No. 6984. Through liquid fermentation, the Streptomyces sioyaensis 107 can produce the active metabolites having effects of inhibiting plant fungal disease pathogenic bacteria such as Rhizoctonia solani and Thanatephorus cucumeris and is an important microbe resource in agriculture.

A living body measuring light source system of a living body measurement apparatus outputs light with a power spectrum as measurement light, in which the light intensity of a characteristic bandwidth including a wavelength (a cause of a local small S/N ratio), which is likely to be absorbed in a known light absorption and scattering wavelength characteristic of a measurement-target living body that is a living body as a measurement target, is set to be higher than that of other bandwidths.

The invention relates to the technical field of transportation, and discloses an aquatic product living body transport case which comprises an outer case body, a case cover and an inner case body, the inner case body is sleeved with the outer case body, the outer case body is covered with the case cover, and a special-shaped frame, a driven ring, a rotating shaft, a guide plate and a metal gasket are arranged in a gap between the inner case body and the outer case body; an oxygen increasing assembly is arranged in the inner box body, the oxygen increasing assembly comprises a metal ring and an elastic net fixedly installed on one side of the metal ring, a hole is formed in the inner wall of the inner box body, the hole and the metal ring are coaxially arranged, and a metal vertical rod is vertically arranged at the lower end of the inner box body. The aquatic products can be poked through the supporting rods, so that the aquatic products are in a tension state, the activity of the aquatic products is kept, gas is pressed into the inner box body from the ventilation opening, the air and the water are fully combined, the oxygen content in the water is increased, the death time of the aquatic products is delayed, and therefore the freshness degree of the aquatic products is kept.

The invention discloses application of a leaf spring to circumcision of tubular tissues of living bodies, and belongs to the technical field of medical instruments. Specifically, the leaf spring is wound around the outer circumference of the tubular tissue of the living body to serve as a cutting board for the tubular tissue; therefore, the circumcision becomes feasible, and operations for formingopen wounds in the patient's abdomen are not needed; an operator only needs to put in the leaf spring via a surgical hole of an original laparoscopic puncture outfit, operate a clamp to hoop the leafspring on the outer wall of a vaginal tube, and circumferentially cut the position, corresponding to the leaf spring, in vagina; in the process, the inner ring surface of the leaf spring acts as thecutting board; on the one hand, different from open-type resection, wound surfaces can be minimized as few as possible, on the other hand, the procedure is completed by one step through circumferential circumcision due to the cutting board, and the efficiency is significantly better than that of existing manual opening and cutting by ultrasonic knifes.
