The global sample of non-invasive prenatal genetic testing developed by Huada Gene accounts for one quarter
The cost of human genome sequencing has dropped from a billion dollars in the early part of this century to a very large amount of less than 10,000 yuan, and the time has been shortened from the past ten years to the present day.
On September 10, at the Global INS Conference 2016 China Zhongchuang Space Industry Summit hosted by Youke Factory and Standards, Peng Zhiyu, chief product officer of Huada, said that it was because of the rapid advancement of technology that humans realized a lot. A dream that was difficult to achieve in the past. Because the price of genetic sequencing is acceptable to ordinary people, this technology will bring good news to human beings.
He said that scientists have found that genes determine human genetics and variation. Only ATCG consists of four letters, but there are more than 3 billion. If you count one letter per second, it takes one hundred years. Since each person's genes are different, big data, large samples are needed, and many genomes are needed to interpret them.
So what can genetic testing do?
For example, non-invasive prenatal genetic testing, screening for Down syndrome.
Down syndrome is often accompanied by facial features, limb deformities and mental retardation. There is currently no good treatment. The best way to prevent this disease is prenatal screening and diagnosis. Traditional Down's syndrome screening is judged by serological indicators, but the false positive rate of this method is relatively high. Among the high-risk population, 98% of suspected patients are not Down's syndrome after further diagnosis. The method of diagnosis is amniocentesis. This requires a long needle to be placed inside the stomach, a fetal sample is collected, and then analyzed. Although this method of detection is accurate, the risk of miscarriage is about 1%.
So, is there a way to ensure high accuracy without risking pregnant women and the fetus?
Peng Zhiyu said that this method is non-invasive prenatal genetic testing. This test initiated clinical trials in 2010 and was widely promoted in 2011. At present, the number of non-invasive prenatal genetic testing samples in the world is about 4 million, of which 2 million are in China, and more than 1 million of these 2 million are in Huada. For China, genetic technology is at the forefront of the world.
Walking aid, as its name implies, is a walking aid. Its function is to support weight, maintain standing balance, and assist walking, so as to realize compensation and improve walking ability.
As an assistive device, walking aids are indispensable in the rehabilitation training process of age, limb disability and limb injury, so how to choose a suitable walking aid is also a learning.
Walking aids are a large category, which can be divided into walking sticks, walking frames and wheelchairs from simple to complex.
What should we pay attention to when using?
1. Adjust the height of the walker according to the user's own conditions. The general principle is correct posture and comfortable use.
2. Necessary inspection shall not be less to ensure safe use.
â‘ Is there any problem with the deployment and storage of the walker; â‘¡ Check whether each part is loose and whether there is burr on the surface of walking aid; â‘¢ Whether the feet or wheels contact the ground smoothly and whether the wheels are flexible; â‘£ The locating pin is not firm, can it be fixed
3. Installation and removal of accessories under specific conditions
â‘ Provide cushion for rest; â‘¡ Sitting bath board for bathing; â‘¢ Toilet board for auxiliary toilet use; â‘£ Shelves and shopping bags for storing things. Use and carry according to the situation, grasp the measure, and the main purpose is to assist walking.
