BEIJING, Dec. 11 (Xinhua) -- A draft regulation on school bus safety management was made public Sunday by the Legislative Affairs Office of the State Council, with the public invited to submit comments on it.The draft stipulates that local governments above the county level should take "overall responsibility" in school bus safety, and authorities of education, public security, transportation and product quality supervision should also properly perform their respective duties.The government will establish and improve a system of mandatory technical standards for the quality of vehicles used as school buses, the draft stated. Primary school students queue up to get on the school bus to go home after school in Deqing County, east China's Zhejiang Province, Nov. 21, 2011. Local government of Deqing County has invested 20 million yuan (3.14 million U.S. dollars) to order 79 school buses, which are specially designed for children with smaller seats and seat belts as well as bright yellow color to have better warning function. Among the 79 buses, 14 ones have truck-style front ends, and this appearance like a long nose can effectively reduce the impact force and better protect children's safety. Drivers of such kind of school buses are required not to exceed 60 kilometers per hour. Nearly 6,000 children from 25 primary schools have benefited from the operation of this kind of school bus in Deqing County.China issued a set of technical standards for school buses for primary school students last year, and the drafting of another standard for buses for the kindergartners is also underway.According to the draft, the government will adopt a license system for school bus operation.Vehicles that are up to school bus standards and with a unified appearance will be first in line to obtain approval from education authorities, and the draft also requires buses to register at the traffic administrative agencies before they can be used as school buses.Instead of compulsory annual safety checks, the draft would require school bus owners to renew their safety qualifications every six months.Drivers should also check the safety condition of the buses before each commute, the draft said.The draft asks schools and the school bus service providers to intensify safety management and maintenance and assign special staff on buses to look after students on board.

WASHINGTON, Dec. 12 (Xinhua) -- British scientists have discovered a new way to target cancer through manipulating a master switch responsible for cancer cell growth. The findings, published Monday in the U.S. journal Cancer Cell, reveal how cancer cells grow faster by producing their own blood vessels.Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumor. These proteins are vascular growth factors like VEGF -- the target for the anti-cancer drug Avastin. Making these proteins requires the slotting together of different parts of genes, a process called splicing.Scientists at the University of West England and the University of Bristol discovered that mutations in one specific cancer gene can control how splicing is balanced, allowing a master switch in the cell to be turned on. This master switch of splicing makes cancer cells grow faster, and blood vessels to grow more quickly, as they alter how VEGFs are put together.In experimental models, the researchers found that by using new drugs that block this master switch they prevented blood vessel growth and stopped the growth of cancers."The research clearly demonstrates that it may be possible to block tumor growth by targeting and manipulating alternative splicing in patients, adding to the increasingly wide armory of potential anti-cancer therapies," the authors said.

BEIJING, Jan. 10 (Xinhua) -- Chinese State Councilor Dai Bingguo on Tuesday attended a reception at the Great Hall of People in Beijing celebrating the 20th anniversary of the establishment of diplomatic ties between China and five Central Asian countries.China successively established diplomatic relations with Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan in early January of 1992.In his address, Dai said relations between China and the five nations have achieved comprehensive and significant progress since they forged diplomatic ties 20 years ago, featuring frequent high-level visits, deepened political mutual trust, mutual support on major issues of each other's concern and expanded mutually beneficial cooperation in various fields.China and the five countries have maintained close coordination within the framework of the United Nations and the Shanghai Cooperation Organization and have positively contributed to safeguarding and promoting the world's peace, stability and development, he said.Noting China and the Central Asian nations are good neighbors, good friends and good partners, Dai said, no matter how the international situation changes, China will adhere to the policy of building friendship and partnership with its neighbors and support the five nations to independently choose their development path.China will unswervingly advance traditional friendship and cooperation with the five nations and will work with them to make unremitting efforts for building a harmonious world of lasting peace and common prosperity, he said.Dai said China will take the opportunity of celebrating the 20th anniversary to increase political mutual trust, expand mutually beneficial cooperation and develop traditional friendship with the five nations, in the hope of jointly creating a bright future for their relations.Li Xiaolin, president of the Chinese People's Association for Friendship with Foreign Countries, and diplomatic envoys from the five Central Asian nations also addressed the reception.
