An international research team led by Chinese researchers said on the 4th that they have completed the largest Chinese genome sequencing and analysis to date, helping to uncover the link between genes and fertility and to understand the genetic structure of China's population.

The study, published in the new issue of Cellular, shows that the Shenzhen Huada Gene Research Institute has collected some genomic samples from more than 140,000 Chinese pregnant women using the “non-invasive prenatal genetic testing” technology. "Non-invasive prenatal genetic testing" is a technique for sequencing small amounts of free DNA in pregnant women to detect chromosomal abnormalities.

The researchers said that the study's sequencing targets accounted for about one-tenth of China's total population, and in addition to the Han nationality, it also covered 36 ethnic minorities. The study identified new genetic loci associated with phenotypes such as height and body mass index (BMI) and also found a unique viral DNA distribution in the Chinese genome. The sequencing results also show that the Chinese have genetic variants common to some Indians, Southeast Asians, and Europeans along the ancient Silk Road.

The study found that a genetic variant called NRG1 is associated with the probability of twins in pregnant women. In addition, a genetic variant is associated with a high concentration of herpesvirus 6 in the blood of pregnant women, which is a common cause of "rose rash" in infants.

Xu Xun, co-author of the paper and dean of the Huada Gene Research Institute, said that although “non-invasive prenatal genetic testing” is low-throughput sequencing, the base number of sequencing targets is large, so the above data still contributes to a global picture of the genetic structure of the Chinese population. Sexual understanding. Rasmus Nelson, a co-author of the paper and a professor of integrated biology at the University of California, Berkeley, said that it is great to get such a large sample size and find out the relationship between genetic variation and human characteristics.

Automatic Massage Foot Bath Machine

The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.
