BEIJING, Jan. 20 (Xinhua) -- China will regulate the production and sale of cosmetic colored contact lenses by including them in its list of items classified as "medical apparatus."Some people wear such non-corrective colored contacts to change or enhance eye color for cosmetic and fashion purposes.As these contacts are not for vision correction and medication purposes, they are currently off limits to the country's medical administration and regulators, said a statement published on the website of the State Food and Drug Administration on Thursday.However, with the increasingly popular use of cosmetic contacts, safety and quality problems due to the regulation loophole are likely to harm consumers' health, and the administration has decided to expand the current medical regulation on contact lenses to cover cosmetic ones, the statement said.It explained that the administration will soon issue a notice to ban the manufacture and sale of these contacts without proper registration and licenses.The statement also warned consumers of the risks of these contacts and suggested they carefully choose and use such products.

BEIJING, Oct. 14 (Xinhuanet) -- Materialism could be harmful to marriage, according to a new study published in the American Journal of Couple & Relationship Therapy Thursday.The researchers collected online "relationship assessment" questionnaires from 1,734 U.S. married couples.The questionnaire covered the topics about the couples' marital satisfaction, conflict patterns, marital communication, and marriage stability, and so on.Non-materialistic couples were about 10 to 15 percent better than those materialistics in their marital satisfaction, marriage stability and conflict levels, according to the study."What we found was a general pattern that materialism seems to be harmful to marriage," said study researcher Jason Carroll, a professor of family life at Brigham Young University.It didn't matter whether the materialistic spouse was the man or the woman, he added.However, materialism is not simply black-or-white: some couples can pursue their fortune and keep their relationship strong at the same time, the researcher suggested.But breaking their materialistic thought would be helpful for most couples, Carroll concluded.

BEIJING, Jan. 4 (Xinhua) -- The Chinese currency Renminbi, or the yuan, rose 8 basis points to a record high of 6.3001 against the U.S. dollar on Wednesday, according to the China Foreign Exchange Trading System.In China's foreign exchange spot market, the yuan is allowed to rise or fall by 0.5 percent from the central parity rate each trading day.The central parity rate of the yuan against the U.S. dollar is based on a weighted average of prices before the opening of the market each business day.

WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

BEIJING, Jan. 8 (Xinhua) -- China canceled over one-third of all official ceremonies, seminars and forums last year in a bid to avoid extravagance or corruption in the use of public resources.Some 2,549 such activities proposed by governments or public institutions, or 37.7 percent of the total applications, which were deemed "ceremonial" and "unnecessary," were cut, saving 1.22 billion yuan (about 193.39 million U.S. dollars), said an official statement released Sunday.The statement was issued by the State Council's Office for Rectifying Malpractices, a ministry-level inter-agency supervisory body dedicated to eliminating administrative irregularities and abuse of power in government agencies, public institutions and major service sectors.Last year's inspections focused on activities co-funded by ministries and local governments, the statement said.The Chinese government agreed with the public that the soaring number of official celebrations, seminars and forums would cost plenty of money and manpower and exacerbate corrupt behaviors.In March, the State Council, or China's Cabinet, ordered 98 ministries and ministry-level government organs to make public their budgets and expenditures on official overseas visits, public vehicles and official receptions -- the "three public consumptions" that had triggered widespread public concern.Premier Wen Jiabao also repeatedly urged the country's government agencies to reduce administrative expenses, including cutting the number of meetings and documents printed.Official figures indicate that the country's crackdown on various forms of extravagant spending by officials saved the country 5.7 billion yuan in 2010.A blue book on China's conferences published in November estimated that the total output of the country's conference industry had reached nearly 1 trillion yuan. Companies made up half of this total, while a considerable portion came from the government and public institutions compared to other social organizations.
