BEIJING, Nov. 16 (Xinhua) -- A senior Chinese commerce official said on Wednesday that the country will work to optimize the import mix of mechanical and electronic products so they can play a bigger role in China's restructuring efforts.Li Jinzao, vice minister of the Ministry of Commerce, made the remarks at a forum of the ongoing 13th "China Hi-Tech Fair" in Shenzhen.His remarks echoed a guideline issued in March on promoting the imports of mechanical and electronic products during the 2011-2015 period, in which China pledged efforts to encourage the imports of high-tech products.Li said that China will improve existing policies to attach more importance to the imports of advanced technology, equipment and components to spur innovation.Meanwhile, he said China will organize more trading events to exchange and cooperate with international businesses, and will continue to push the United States and European countries to ease restrictions on civil high-tech exports to China.

WASHINGTON, Dec. 7 (Xinhua) -- The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida.Their report, published on-line Wednesday in Gynecologic Oncology, suggests that this combination, ixabepilone and sunitinib, might offer a much needed treatment option for women with advanced ovarian cancer.Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it."Women die from ovarian cancer because their tumors become resistant to chemotherapy, so a drug that might be able to reduce that resistance -- which may be what this combination of agents is doing -- would be a boon to treatment of this difficult cancer," says study coauthor Gerardo Colon-Otero.The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. It might be a potential biomarker that may help identify patients who might benefit from such combination therapy, the researchers say.

BEIJING, Jan. 21 (Xinhua) -- As the Chinese Spring Festival travel rush enters its peak period, more work staff and transport resources have been deployed to ensure safe and convenient transport during the world's largest annual human migration.At 8 a.m. on Jan. 20, two days ahead of the Chinese New Year, Dong Leihong, duty officer at the road network center with the Ministry of Transport (MOT), sat before a huge monitoring screen that displayed real-time highway transport conditions nationwide."Good news! The fog has almost all lifted. Only some local lines in Shanxi province have been blocked by snow. Road transport in the country's other regions is normal," Dong said.The screen showed that some work staff at local toll stations in Shanxi were clearing away the snow, while vehicles were running smoothly despite rain on a section of the Shanghai-Kunming Highway located in eastern Jiangxi province.About 840,000 passenger cars were put into service to meet the day's road travel demand, MOT Spokesman He Jianzhong said at the center. An estimated 82.9 million passenger trips by bus were recorded that day, an increase of 10.8 percent from a year earlier.Passenger trips are expected to rise 9.1 percent year-on-year to hit 3.16 billion during this year's festival travel period, prompting the country's transport system to mobilize more resources.Moreover, the railway, aviation and public security sectors have also adopted multiple measures to embrace the heat of the ongoing 40-day travel rush that started on Jan. 8.At Beijing Railway Station's control center, where the exact information of the location and speed of an operating train as well as train failures is available, more than 80 dispatchers were hired to coordinate the operations of passenger and cargo trains running in north China.Meanwhile, large numbers of police, railway workers and volunteers worked in the whipping winter wind to help with boarding at Beijing West Railway Station.The country required all train ticket buyers to register with their names and have their ID cards checked prior to boarding, a real-name system introduced to stem ticket scalping that has plagued the Spring Festival travel rush for years.Counters dealing with domestic flights also extended service hours at the Beijing Capital International Airport, and more staff members were on site to help with security checks, said Li Guanghui, the airport's general manager.The airport saw about 140,000 departure passengers on Jan. 20, an increase of 29 percent from a year earlier, according to Li.To help road travellers deal with emergencies, the Ministry of Public Security established 8,300 service stations nationwide to provide car repair, medical care, rest and guidance services.Some local transport departments also prepared drinking water, food, and cotton clothes to ensure supplies in case of traffic jams on highways.The local traffic police department in Zhaoqing, a city in southern China's Guangdong province, set up 17 rest stops for long-distance motorcyclists at several national highways that pass through the city.The move aims to provide food and other emergency services for the 20,000 people that travel by motorcycle on these highways each day during the festival travel rush.The Spring Festival, or "Chunjie" in Chinese, is a time for family reunions. It is the country's most important festival.

WASHINGTON, Dec. 5 (Xinhua) -- Young women may reduce their risk of developing cardiovascular disease simply by eating more fish rich in omega-3 fatty acids, researchers reported Monday in Hypertension: Journal of the American Heart Association.In the first population-based study in Danish women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.About 49,000 women, 15-49 years old, median age of just under 30 years in early pregnancy -- were interviewed by telephone or answered food frequency questionnaires about how much, what types and how often they ate fish, as well as lifestyle and family history questions.Researchers recorded 577 cardiovascular events during the eight- year period, including five cardiovascular deaths in women without any prior diagnosis of the disease. In all, 328 events were due to hypertensive disease, 146 from cerebrovascular disease, and 103 from ischemic heart disease. Inpatient and outpatient admission for cardiovascular disease was much more common among women who reported eating little or no fish. In three different assessments over a 30-week period, women who never ate fish had a three-fold higher disease risk compared to women who ate fish every week."To our knowledge this is the first study of this size to focus exclusively on women of childbearing age," said Marin Strom, lead researcher and post doctoral fellow at the Center for Fetal Programming, at Statens Serum Institute in Copenhagen, Denmark. " We saw a strong association with cardiovascular disease in the women who were still in their late 30's."Fish oil contains long chain omega-3 polyunsaturated fatty acids, which are believed to protect against heart and vascular disease. Few women in the study took fish oil supplements, so these were excluded from the analyses and the results were based on the dietary intake of omega-3 fatty acids, not intake from supplements.The most common fish consumed by women in the study were cod, salmon, herring, and mackerel."Our study shows that for younger women, eating fish is very important for overall health, and even though we found cardio- protective effects at relatively modest dietary levels, higher levels may yield additional benefits," Strom said.
