The invention discloses a method for inducing Stichopus Japonicus Selenka to lay eggs in vivo, which is characterized by simple operation, short time, synchronous egg laying, large discharge quantity and good quality of eggs, and capability of greatly improving induction rate, fertility rate and hatching rate; the method is implemented as the following steps: dissolving NGLWY acid amides in ultrapure water to formulate 1 mumol/L mother liquor, then dissolving the mother liquor in 0.5mol/L KCl sea water solution to prepare 1nmol/L inducer; selecting gonad mature parent Stichopus Japonicus Selenka with the weight being at least 200g; injecting the inducer with the ratio of volume and the weight of parent Stichopus Japonicus Selenka being 0.1% ml/g but less than 0.3ml into coelom from the back of the Stichopus Japonicus Selenka to perform in vivo induction; and collecting the eggs.

The invention discloses a method for preparing an inhibin genetic engineering regulation antigen, which comprises the following steps: cloning an inhibin encoding gene; making use of the inhibin encoding gene to prepare an inhibin recombinant fusion protein; and making use of the inhibin recombinant fusion protein to prepare the inhibin genetic engineering regulation antigen. The method for preparing the inhibin genetic engineering regulation antigen has the advantages of simplicity, high purity, good immunogenicity, low price and the like; the inhibin genetic engineering regulation antigen prepared by the method does not have toxicity, pathogenicity and drug residue, is harmless to human and animals, has no adverse effect on consumers, can improve the ovulation rate and the litter size, improve utilization ratio of a superovulation embryo, promote the sexual maturation so as to improve the reproduction and the like.

The invention belongs to the technical field of medical information and discloses an information acquisition system for a joint marker for diagnosing PCOS (polycystic ovarian syndrome). The information acquisition system for the joint marker for diagnosing the PCOS comprises an excessive androgen measurement module, a serum extraction module, a central control module, a joint marker testing module, a treatment module, a data storage module and a display module. A detection kit can realize high-sensitivity and efficient detection and has the characteristics of low detection cost and good repeatability. Meanwhile, pharmaceutical composition provided by the treatment module and used for the excessive androgen type PCOS comprises medicinal materials including herba epimedii, fritillaria, fructus psoraleae, antler slices, hippocampus, tortoise plastron and the like, does not contain radix et rhizoma rhei or radix angelicae sinensis, notably reduces the androgen level of a patient, improvesgrowth of ovarian follicle and increases the ovulation rate and the pregnancy rate of the patient in the child-bearing period after being taken for a period of time.

The invention provides a method for increasing the ovulation rate of sinonovacula constricta (Lamarck) parent oysters and guaranteeing ovulation synchronism. An inonovacula constricta (Lamarck) parent oyster ovulation device employed comprises a rectangular bottom frame, supporting rods, a shielding film and a light-dimming window, wherein small holes are drilled in the four corners of the bottom frame, the four supporting rods are inserted into the small holes to form a cuboid-shaped frame, the shading film as high as the supporting rods is put to surround the cuboid-shaped frame, and the light-dimming window is paved at the top of the cuboid-shaped frame; the bottom of the bottom frame is covered with a nylon net; an air inlet pipe is laid in the longitudinal direction of the bottom frame; three air stones are connected under the air inlet pipe. When the inonovacula constricta (Lamarck) parent oyster ovulation device is applied for ovulation, the light intensity in the light-dimming window is controlled at 200Lx, and therefore, the ovulation synchronism of the inonovacula constricta (Lamarck) is guaranteed, and meanwhile, the ovulation rate of the sinonovacula constricta (Lamarck) parent oysters is greatly increased and the shortcomings of the prior art are solved; meanwhile, the whole device is very convenient to assemble and disassemble, easy to clean and low in cost, and cannot be corroded by seawater; the method can be popularized in actual production very easily.

The invention discloses an FLIP protein and new applications of encoded genes thereof. The new application of the invention refers to the application of the FLIP protein and the encoded genes thereof in blocking apoptosis induced by FADD and the application in inhibiting apoptosis of ovary granular cells and the application in promoting reproductive performance of animals. The FLIP protein and the encoded genes thereof can obviously inhibit apoptosis of the ovary granular cells induced by FADD, promote growth of oocyte, reduces follicular atresia and serve as potential medicines for improving reproductive performance of cows. The protein and the new applications of the invention provide relatively reliable and concrete experimental basis for increasing ovulation rate of dams and improving reproductive performance thereof, thus enjoying a wide application prospect in improving the reproductive performance of female animals.

The invention provides a method for facilitating ovulation of kelp female gametophytes. The method includes the steps: resuscitating kelp germplasm filaments in seawater, crushing kelp germplasms, andfiltering crushed liquid to obtain filament fragments with the lengths of 3-6 cells; performing aerated suspension culture on the filament fragments under the conditions of the illumination intensityof 6000+/-300lx, the illumination cycle of L:D=12h:12h and the temperature of 15+/-1 DEG C to collect eggs; culturing the collected eggs to obtain young kelp sporophytes, culturing the young kelp sporophytes, and performing culture by running water at the stage of young sporophytes of two rows of cells. According to the method, female kelp germplasms can ovulate in 11-13 days, ovulation time is shortened, ovulation rate is high, ovulation synchronization is good, ovulation rate within two days can reach 65-70%, and egg development rate can reach 70-80%. According to the built culture method of young sporophytes, the aberration rate of the young sporophytes can be reduced to 50-60%.

The invention relates to a medicinal composition for a high-androgen polycystic ovary syndrome. The medicinal composition comprises a Chinese medicinal composition and a chemical medicament, wherein the Chinese medicinal composition comprises the following medicinal materials: epimedium, caladium, fructus psoraleae, sliced deerhorn, sea horse, tortoise plastron and the like, and does not contain rhubarb and Chinese angelica. The medicinal composition can reduce the level of androgen and androgen receptors of polycystic ovary syndrome (PCOS) patients, improve the level of sex hormone binding globulin, reduce the level of free testosterone, improve the level of in-vivo estrogen further, improve the growth and development of follicles, and improve the ovulation rate and pregnancy rate of thepatients.
