Pseudobagrus ussuriensis genetic male reversal physiological female fish breeding sifting method

The invention discloses a pseudobagrus ussuriensis genetic male reversal physiological female fish breeding sifting method. The method comprises the steps of incubating fry, selecting testing fry, incubating artemia, soaking artemia with an estradiol solution, regarding artemia as a hormone carrier to be fed to the fry, observing physiological genders of fingerlings and adult fish, and identifyinggenetic genders. Through optimized procedures, a proper feeding starting time, the concentration and time of the estradiol solution for soaking the artemia, the feeding lasting processing time are sifted, the genetically male individuals are genetically reversed into physiologically female individuals, male specific molecular markers are utilized to identify the genetically male physiologically female individuals to be subjected to separate-pond breeding, and breeding is conducted according to the breeding technological path of male fish sexual reversal, artificial gynogenesis, super-male fish and all-male fish. By means of the pseudobagrus ussuriensis genetic male reversal physiological female fish breeding sifting method, a large quantity of high-quality fundamental materials are provided for pseudobagrus ussuriensis all-male-fish breeding within a short period.

Oligonucleotides and usage thereof in preparation of medicine for preventing and curing myocardial hypertrophy and heart failure

The invention belongs to the technical field of medicines, and particularly relates to 5'-AACGTT-3'-containing oligonucleotides, a functional analogue of the oligonucleotides, and usage of the oligonucleotides or the functional analogue of the oligonucleotides for preventing and curing myocardial hypertrophy and chronic heart failure. The oligonucleotides and the usage realize the function of the 5'-AACGTT-3'-containing oligonucleotides by using myocardial cells and animal hypertrophy models acknowledged in the academia at home and abroad. The experimental result shows that the 5'-AACGTT-3'-containing oligonucleotides can obviously restrain the expression of a landmark protein ANF (atrial natriuretic factor) and a beta-MHC (major histocompatibility complex) gene of the myocardial hypertrophy, and can restrain the increase of a superficial area of the myocardial cell, and the restrain function of the oligonucleotides depends on the dosage of the oligonucleotides.. In the whole experiment, the 5'-AACGTT-3'-containing oligonucleotides can obviously restrain the myocardial hypertrophy and the increase of the heart-body ratio, and the happening of myocardial necrosis can be reduced. The experiment result disclosed by the invention prompts that the 5'-AACGTT-3'-containing oligonucleotides is the medicine for effectively curing the myocardial hypertrophy and the heart failure.
