BEIJING - A research team led by Chinese scientists have discovered dietary modulation of gut microbiota(膳食干预肠道菌群)can alleviate both genetic and simple obesity in children.
The findings of the team, led by Zhao Liping with Shanghai Jiaotong University, Yin Aihua with the Guangdong province children's hospital, and Tang Huiru with Chinese Academy of Sciences, have been published on EBioMedicine, a renowned medical journal co-sponsored by Cell and The Lancet in July.
The team identified bacterial genomes specifically for producing obesity-related metabolites(代谢物), and said an improved gut microbiota can significantly help to treat genetic obesity such as Prader-Willi Syndrome (PWS).
Beginning in childhood, PWS affected kids develop an insatiable appetite, leading to chronic overeating and obesity.
The scientists used a diet therapy with beneficial gut bacteria on trial patients and found considerable diminished appetite, weight loss and improved health conditions on the patients.
The paper concluded dysbiosis(失调)of gut microbiota is highly related with both genetic and simple obesity in children, implicating dietary modulation of gut microbiota a potentially effective treatment method.

When you think of success, you think of relative achievements in your own world. Each element of your world is important to you, and there is no need to compare with others. You cannot affect the success of others; you can affect your own success.
Success is very much achievable to everybody. Believe that and you have taken the first step. If you do not believe in yourself, then building self-esteem is your first task.

Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Many people are afraid to support themselves. Dr. Robert Albert, author of Stand Up, Speak Out, and Talk Back,thinks it’s because their self-respect is low. “There s always a ‘superior’ (长辈) around ˉa parent, a teacher, a boss—— who knows better.” But Albert and other scientists are doing something to help people help themselves. They offer “assertiveness(维护) training” courses——A.T. for short. In the A. T. Course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive (进攻的) without hurting other people. In one way, learning to speak out is to get rid of fear. A group taking an A. T. Course will help the timid (懦弱的) person to lose his fear. But A. T. uses an even stronger motive (动机)——the need to share. The timid person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-respect. If someone you face is more “important” than you, you may feel less of a person. You start to doubt your answers to problems. You can get to feel good about yourself. And once you do you can learn to speak out. The problem the writer talks about is that…
A.some people buy things they don t want |
B.some people are afraid to speak out for their rights |
C.there are too many superiors |
D.some people don t think enough of themselves |
