Embodiment 1

[0111] 1. Research object

[0112] A total of 50 Tibetan populations were selected as plateau hypoxia adaptation group, 25 males and 25 males, aged 18-55 years, with an average age of 33.9±8.3 years; at the same time, 166 plain Han populations were randomly selected as the control group, 82 males and 84 females. Families, aged 13 to 45 years, with an average age of 33.6±9.2 years. In addition, 50 healthy men of the Han nationality in the plains were selected to enter the plateau, aged 19-23 years, with an average age of 20.9±1.0 years old, and their hematological indicators before and after the plateau were detected, and 20 of them were used as the observation group. The screening criteria: the difference in HGB concentration before and after entering the plateau ≥35g / L, RBC count difference ≥1×10 12 / L and Hct difference ≥ 0.1, the remaining 30 as the control group.

Abstract

The invention relates to the technical field of rock body selection, and in particular relates to a method for selecting a red sand stone, and the method comprises the following steps: 1) primarily screening and grading the red sand stone; 2) performing strong magnetic deliming and cleaning; 3) dissolving fluorosilicic acid, magnesium sulfate and light burning powder in water to prepare a soakingliquid, soaking the red sand stone in the soaking liquid, and then drying the red sand stone after picking up; 4) after the red sand stone is dried, spraying the red sand stone with a vegetable dye evenly until saturation, until the vegetable dye is absorbed by the red sand stone, further spraying the red sand stone with the vegetable dye for 2 to 3 times, and drying to obtain a selected red sandstone; wherein the vegetable dye is mainly prepared from safflower, rhus coriaria fruit, rose, trisiloxane polyoxyethylene ether, acetic acid and absolute ethanol. The method is simple in operation, can effectively strengthen the strength of the red sand stone, reduces the weathering erosion degree of the red sand stone, makes the red sand stone bright in color, improves the texture and visual effect of the red sand stone, thereby improving the quality and qualified utilization rate of the red sand stone.

Description

technical field [0001] The invention relates to the technical field of genetic engineering, in particular to the application and screening method of EPAS1 gene tag single nucleotide in screening people adapted to plateau environment. Background technique [0002] my country is a mountainous plateau country, and the plateau area above 3,000 meters accounts for 1 / 4 of my country's land area, which is the main direction and main battlefield of the western development. Among them, the Qinghai-Tibet Plateau is the most important area, which is rich in resources (minerals, petroleum, water conservancy, tourism, etc.) and needs to be developed urgently. At the same time, the Qinghai-Tibet Plateau is also an important national defense and military support area in my country. [0003] However, for people who are new to the plateau, high altitude hypoxia can cause altitude sickness. Common symptoms include headache, insomnia, loss of appetite, fatigue and dyspnea. Generally speaking...
