吉安医学整形美容整形科井岗山市妇幼保健院玻尿酸多少钱Scientists have unravelled one of the secrets of a plant used in traditional Chinese medicine.科学家解开了传统中药中一种植物的奥秘.The Chinese skullcap - known as Huang-Qin - is traditionally used for fever, liver and lung problems.中国黄芩传统上用于治疗发烧,肝病和肺病.Scientists have discovered that the plant uses a special pathway to make chemicals with potential cancer-fighting properties. They say it is a step towards being able to scale up production to make new drugs.科学家发现,这种植物用特殊途径合成具有抗癌潜力的化学物质. 科学家表示, 这朝着规模化生产新药迈进了一步.Prof Cathie Martin, of the John Innes Centre in Norwich, is lead researcher of the study, published in Science Advances. Working in collaboration with Chinese scientists, her team deduced how the plant, Scutellaria baicalensi, synthesises the chemicals, known as flavones.诺维奇约翰英纳斯中心的凯茜.马丁教授, 是这项研究的首席研究员, 该研究发表在《科学进展》上. 她的团队与中国科学家合作, 推断出黄芩是如何合成黄酮这种化学物质的.Flavones are found widely in the plant kingdom, giving some plants vivid blue flowers.黄酮广泛见于植物王国, 让一些植物开出鲜艳的蓝花.Understanding the pathway should help us to produce these special flavones in large quantities, which will enable further research into their potential medicinal uses, said Prof Martin.“理解黄酮的生成途径, 有助于我们大量生产这些特殊物质, 有利于进一步探索它们潜在的药用价值.”Previous lab research suggests that flavones have anti-cancer properties, offering hope that they may one day lead to effective cancer treatments.之前的实验室研究表明,黄酮具有抗癌特性, 为有朝一日或可用于有效的癌症治疗提供了希望.Commenting on the study, Dr Alan Worsley of Cancer Research UK, said: ;This paper answers a very interesting biological question about how these plants are able to make particular molecules, but the study doesn#39;t look at whether the molecules can be used to treat cancer.英国癌症研究中心的沃斯利士对该研究说: “这篇论文回答了这些植物如何能够合成特定分子这个非常有趣的生物学问题, 但研究并没有探讨特定分子能否用于治疗癌症.”This herb is a member of the mint family and native to China. In traditional Chinese medicine, the root was used in combination with other plants to treat fever and other ailments.黄酮属于薄荷科,是中国本土植物. 传统中药中,这种根茎类植物和其它植物结合使用,治疗发烧和其它病痛.There is increasing scientific interest in ancient medicinal plants. In 2015, Tu Youyou was awarded the Nobel Prize for Medicine for her work on artemisinin, an antimalarial drug derived from the sweet wormwood plant, Artemisia annua.对古老药用植物的科学兴趣正在与日俱增. 2015年, 屠呦呦因其在青蒿素方面的工作被授予诺贝尔医学奖. 青嵩素是从青嵩中提取的抗疟药. /201604/437139吉安治疗狐臭多少钱 There are a few aspects of a wedding that show things may not be as happy as they seem.婚礼当天的几个方面表明新婚夫妇并不是像他们表面那么幸福。Sometimes a marriage just doesn’t work, no matter how much the two parties try.有时候结婚也并没有什么作用,无论男女双方多么努力。But according to Reddit user Modern Day Cinderella (who has worked at more than 100 weddings), when asked the question ;what happened at a wedding that let you know the marriage was going to end in divorce?;, she’s seen all the clues that the happy couple’s future may not last.但是依据红网用户“当代灰姑娘”(在100多场婚礼上工作过),当问到她这个问题“婚礼当天发生的什么事情会让你认为新婚夫妇最终会离婚?”,她注意到了所有标志着新婚夫妇未来不会长久的所有迹象。Modern Day Cinderella says that how a couple cut the cake is a big tell-tale sign.“当代灰姑娘”说新婚夫妇切蛋糕的方式是最有用的预兆。“During the cake cutting, most brides will say don#39;t smash the cake in their face (or vice-versa). If the other person does it anyway, that#39;s a huge tell for respect.”“在切蛋糕的时候,大多数新娘都会说不要将蛋糕扔到她们的脸上(或者新郎说不要扔到他们的脸上)。如果另一方却将蛋糕扔到克对方脸上,这是最大的预兆。”“I know it#39;s all fun and games, but it#39;s a big tell to overall feelings.”“我知道这只是开玩笑的游戏,但是却能很明显反应整体的感觉。”She also says another indication is how the bride and groom deal with the stress of the day.她还说了另一个标志,就是新娘和新郎如何应对婚礼当天的压力。“I have to be the one that tells them, #39;look, I know you#39;re p***d at each other right now, but for the sake of your lifetime memories, fake that you like each other for the rest of the night.’”“我得告诉他们‘看,我知道你们现在很渴望对方,但是为了你们一生的美好回忆,还是在晚上剩余的时间再享受吧。’”Then there’s the bridezilla – or the groomzilla, as ModernDayCinderella points out.“当代灰姑娘”还指出,有的时候会有比较难缠的新娘或者新郎。“If you#39;re a Bride or Groomzilla then that#39;s a tell, too. All of my monsters have been absolute control freaks and refuse to let people help them, but then get p***d that nobody helps them.如果你是一个难缠的新娘或者新郎,那么这也是一个预兆。我的所有魔鬼都是绝对的控制狂,而且拒绝其他人的帮助,但是他们还是会与帮助他们的人发生关系。 /201607/454352吉水县人民中医院绣眉手术多少钱

吉安水光针注射瘦腿哪家医院好What scholar Zheng Zhenzhen of Chinese Academy of Social Sciences said at the 2016 World Economic Forum has stirred aheated discussion about the Chinese population. According to Zheng, China#39;s population will reduce to 1 billion by the end ofthis century, just like the volume it had reached by 1980.中国社会科学院学者郑真真在2016年世界经济论坛上的发言引起了一场关于中国人口的激烈讨论。她声称,本世纪末中国人口将减少到1980年的水平,也就是10亿人。However, some experts think a 1 billion population is still a number too optimistic, considering the overestimate of fertilityrates, they point out that the Chinese population may possibly reach 600 million by 2100.然而,一些专家认为10亿人仍是一个太过乐观的数字,他们指出,考虑到对生育率的过高估计,中国人口在2100年可能低至6亿人左右。A demography scholar Huang Wenzheng from the University of Wisconsin considers it is impossible that China could still have a 1 billion population by the end of the century. Even assuming with a total open birth policy, the birth rate can be 20 percent higher than the one during 2010 to 2015, and the average life expectancy also keeps increasing, Huang estimated the total population of China in 2100 would be 580 million, and decrease to 280 million by 2150.此外,美国威斯康星大学人口统计学学者黄文政也表示,到本世纪末,中国人口很难维持到10亿人的水平。即使大力鼓励生育,假设生育率比2010年至2015年的实际生育率高出20%,再假设中国未来人均预期寿命随社会发展水平上升而变化,他预测中国2100年的总人口为5.8亿,到2150年会降至2.8亿。Another Scholar Yi Fuxian predicts that with the universal two-child policy carried out in 2016, the birth rate still only would rise from 1.25 in 2015 to 1.4 in 2017. And based on the previous experience of South Korea and Taiwan, the birth rate would be down to 1.1 in 2035, and then up to 1.30 in 2056. Supposing that the birth rate can remain at 1.3 until 2100, the population of China would be only 560 million.另一位学者易富贤则预测,尽管2016年全面两孩政策放开,出生率仍然只会从2015年的1.25上升到2017年的1.4。基于韩国和台湾的经验,出生率在2035年会下降到1.1,到2056年再上升到1.3。假设到2100年出生率可以一直保持1.3不变,那时中国的人口将只有5.6亿左右。According to the 2015 World Population Prospects released by ed Nations on July 2015, China#39;s population will be 1.004 billion by the end of this century, which is based on its medium variant. Based on low variant, the prediction on population is 613 million.根据联合国2015年7月发布《2015年世界人口展望》,预计中国人口到本世纪末将回落到10.04亿。这是联合国的中预测值,其低预测值是6.13亿。Scholars think it is unreasonable for the UN to assume such high a fertility rate of China based on the real situation. The report set the birth rates 1.55 from 2010 to 2015, 1.59 from 2015 to 2020, 1.66 from 2020 to 2030,1.74 from 2045 to 2050,and 1.81 from 2095 to 2100. While China#39;s birth rates from 2010 to 2013 was 1.18, 1.04, 1.26, and 1.24.学者们认为,根据实际情况,联合国为中国假定如此高的生育率是不合理的。在联合国预测方案里,中国2010年至2015年的生育率被假设为1.55、2015年至2020年为1.59、2020年至2030年为1.66、2045年至2050年为1.74、2095年至2100年为1.81,而中国2010年到2013年的生育率分别为1.18,1.04,1.26,1.24。Huang explains that now there are only 17 million new born babies every year. In the next 10 years, the number of Chinese women aged from 23 to 30 would be down by 40 percent. Even if there are 8 million babies being born every year, the birthrate could reach the replacement level, and every one can live to one hundred years of age, Huang estimates the population would still only be 800 million by 2100.黄文政解释称,现在每年只有1700万名新生儿。在未来10年内,23到30岁的育龄女性人数将下降40%,即使每年出生800万名婴儿,生育率达到更替水平,每个人都活到一百岁,他估计2100年中国人口也不过8亿左右。 /201607/453911吉安市中医院激光去痣多少钱 吉安中医院整形美容科
