SINGAPORE, Sept. 7 (Xinhua) -- Singapore scientists have found possible new ways to treat a type of aggressive breast cancer that is unresponsive to current forms of treatment, local broadcaster Channel NewsAsia reported on Wednesday.The team of scientists at the Genome Institute of Singapore ( GIS) and National University of Singapore (NUS), led by GIS senior group leader Qiang Yu, found that the enzyme EZH2 acts by inhibiting genes that stop the growth of tumors in the body.The insights could open the door to developing more effective treatment for fast spreading breast cancers, especially the estrogen receptor-negative breast cancer that is common all over the world.It was also found that through EZH2, cancer is promoted in the body by activating specific genes that impact breast cancer progression and cancer stem cell self-renewal.Yu said the new understanding on how EZH2 works as a cancer- causing gene in breast cancer has important therapeutic implication."The results suggest that small molecule drugs that block enzyme activity of EZH2 may not work for cancers caused by EZH2's activation genes," Yu said.Currently pharmaceutical companies have been developing drugs only to the block EZH2 enzyme activity so that tumor suppressers can perform their protective role in blocking cancer growth.Researchers said the next step would be to develop biomarkers to identify tumors with EZH2.This step would enable better treatment methods, with one of options being the development of therapies that shut down EZH2 completely and not just inhibit its enzymatic function.The findings have been published on the journal Molecular Cell.

BEIJING, June 11 (Xinhua) -- The Baidu Charitable Foundation (The Baidu Foundation) and The Bill & Melinda Gates Foundation (The Gates Foundation) founded a strategic charitable alliance here Saturday, in a bid to work for a healthy, smoke-free environment both in China and around the world.Li Yanhong, president of Baidu company, China's top online search engine operator, and Bill Gates, co-chair and trustee of the foundation under the names of the couple, attending the ceremony, both wore a shirt that said, "Say No to Forced Smoking."In his speech at the ceremony, Bill Gates said, "This will be a long-term, open-ended alliance. As a sponsor, Mr. Li and I would like to welcome more partners, and we expect to see more Chinese enterprises and all facets of society to focus on public health issues together."Li Yanhong also addressed the meeting, claiming, "Living healthy and green has become a common pursuit of mankind. We hope the alliance can bring together public efforts for this global cause, so that more people can benefit from our endeavor." ' The alliance's first action is to comply with the government ban on smoking in public places and refuse forced smoking, according to a press release from the foundations.Targeting "forced smokers," the alliance will carry out educational campaign through all channels of media to educate and promote self-awareness about the dangers of forced smoking. Moreover, it will also help existing smokers, especially those who are underage, by sharing scientific methods for quitting.Smoking is one of the world's eight primary causes of death, leading to lung disease, cancer, heart disease, low birth rate, fetal death, tuberculosis, high mortality and many other health issues. Smoking forces many families into poverty by causing both poor health and premature death.China ranks first in tobacco consumption and production in the world. China has 300 million smokers, and one in every three cigarettes smoked in the world is smoked in China. More than half of Chinese smokers are male; and more than 1 million people die from smoking related diseases each year.In addition, China has 740 million "forced smokers," whose health also suffers. The World Health Organization (WHO) notes that there is no safe level of second-hand smoke.This year, China published its 12th Five-Year Plan (2011-2015) that clearly stipulates for "implementing a full-scale ban on smoking in public facilities." This is the first time that tobacco control has been included as part of China's five-year plan for national economic and social development."Rules for Implementation of Public Facilities Health Management Regulations," effective since May 1st, also specifies to "ban smoking at all public indoor facilities," providing legal basis for non-smokers to protect their rights of health and to refuse "involuntary smoking."Aside from tobacco control, the strategic alliance co-founded by the foundations will also collaborate on a series of projects, such as AIDS prevention and control, in a joint effort to promote health for mankind.Founded in 2000, the Gates Foundation currently carries out charity projects in over 100 countries. Since establishing the Beijing Representative Office in 2007, the Gates Foundation has supported a range of health and development projects in China, including the advocacy of smoke-free environment, AIDS and tuberculosis prevention and control, and agricultural development and research projects.Launched in 2010, the Baidu Foundation is committed to use information technology for support of youth and disadvantaged groups, focus on the environment and promote social harmony.Ever since Baidu was founded, Li has actively pushed for tobacco control within the enterprise and the industry. He is the only Chinese member of the United Nation AIDS Prevention Senior Committee and also board member of the HuaXia Charity Foundation.

XI'AN, Sept. 18 (Xinhua) -- At least 12 people were killed and 22 others missing over the weekend in rain-triggered landslides in northwestern Shaanxi Province, local officials said.As of 5:30 p.m. Sunday, rescuers had retrieved 10 bodies from beneath the rocks and mud in Baqiao District of the provincial capital of Xi'an, while another five were injured, said Zhu Zhisheng, vice mayor of Xi'an, who was at the site.Another 22 people remained missing, Zhu said, adding the injured were hospitalized and in stable condition.The landslide around 2 p.m. Saturday unleashed about 100,000 cubic meters of rock and mud down the mountain, engulfing a brick factory and destroying part of a nearby ceramics factory in the suburban district of Xi'an.Rescuers found four bodies on Saturday night and six others were retrieved on Sunday.More than 700 police, firefighters and local residents joined the rescue which went on Sunday night.However, the rescue was hampered by three ensuing slides between 10 a.m. and 11 a.m. Sunday as heavy rains continued slashing the city.About 10,000 cubic meters of newly-triggered rock and mud roared down to the site, forcing rescuers to suspend searching temporarily.Heavy downpours in the province also caused havoc in other areas.A heavy rainfall on Saturday night triggered a landslide that buried a residential house in the suburban district of Jintai in Baoji City, some 175 km to the west of Xi'an.Two people were dug out but later died after they were rushed to a nearby hospital, the municipal government of Baoji said in a statement Sunday.The downpours also brought a landslide in the same district early Sunday morning. Three people were saved and sent to a local hospital, according to the statement.The three wounded were in stable condition, doctors at the hospital said.

BEIJING, June 10 (Xinhua) -- The nation's drug watchdog on Friday publicized a draft national standard of sulfur dioxide residue in Chinese herbal medicine, which is open for public opinion until Sept. 9 this year.The maximum amount of sulfur dioxide residue is 400 mg in one kg of each of 11 specified kinds of herbal medicine, such as Chinese yams, Gastrodia elata and Codonopsis pilosola, according to the draft standard unveiled by the State Food and Drug Administration (SFDA).The standard provides a 150-mg-per-kg limit for all other kinds of herbal medicine.Fumigation with sulfur is used as a way of drying some herbal medicine by growers, and currently have no alternative that is both cheap and convenient.The SFDA said it doesn't favor the drying herbal medicine through fumigation with sulfur and urges research efforts to invent new alternatives.According to the World Health Organization, the tolerable maximum amount of sulfur dioxide that a human body can take in one day is 0.7 mg per kg, which means that an adult of 60 kg should not take in more than 42 mg of sulfur dioxide a day.Long-term exposure to high amounts of sulfur dioxide can cause damage to human body, especially the respiratory system, according to experts.
