BEIJING, Dec. 23 (Xinhua) -- The personal information of more than 6 million Internet users on CSDN, or China Software Developer Network, the country's largest programmers' website, was leaked by hackers, raising concerns about web security and triggering widespread panic.The leak was first exposed by China's leading anti-virus software provider, Beijing-based Qihoo 360, on Wednesday. The company said the leak included user IDs, passwords and e-mail addresses in clear text.The hacking case escalated on Thursday after the personal details of subscribers to more websites, including popular online gaming and social networking sites, were leaked.Online media reports said the personal data of up to 50 million Internet users has been leaked so far, but the number could not be independently verified.In response, the National Computer Network Emergency Response Technical Team/Coordination Center of China (CNCERT/CC) issued a statement Thursday, saying the CSDN's user data bank that leaked on the Internet was created before April 2009 and the passwords were stored in clear text, but the passwords had been encrypted after the data bank was upgraded in April 2009."Therefore, similar security problems have not been found in the newest user data bank," the statement said.Technical experts are investigating how many websites and users were actually involved in the hacking case, said Zhou Yonglin, director of the CNCERT/CC Operating Department."False information and exaggerations cannot be ruled out," he said.Nevertheless, CNCERT/CC has ordered CSDN to take immediate action in repairing the system hazards and providing users with timely security solutions.Computer security experts at Qihoo 360 believe the leak has spread to other websites."Many Internet users have registered the same passwords for their e-mail, microblog, online gaming and online payment accounts, so, if the server of one of the websites is hacked, their accounts and passwords on other websites would also be stolen," said Qihoo 360's Dr. Shi Xiaohong.Police authorities in Beijing told Xinhua on Friday that an investigation has been launched.WEB SECURITY IN QUESTIONDisgruntled Internet users in China rushed to change their passwords after the leak occurred, the largest of its kind in the history of China's Internet development."It is very annoying. I had to spend almost an hour changing the passwords of all my online accounts, especially those for payment accounts," said Li Xing, a white-collar worker at a technical company in Beijing.

BEIJING, Dec. 31 (Xinhua) -- In a New Year's address broadcast on Saturday, Chinese President Hu Jintao vowed that China will continue to develop friendly exchanges with other countries and positively participate in international cooperation on global issues.While addressing domestic and overseas audiences via state TV and radio broadcasters, Hu urged the acceleration of the transformation of the country's economic development pattern and structural adjustments while making more efforts in ensuring people's livelihood.The country will continue to balance maintaining steady and relatively fast economic growth with adjusting its economic structures and managing inflation expectations, he said in the speech titled "Jointly Improve World Peace and Development," which was broadcast by China Radio International, China National Radio and China Central Television.A photo released on Dec. 31, 2011 shows Chinese President Hu Jintao delivering a New Year address, titled "Jointly Improve World Peace and Development", to domestic and overseas audiences via state TV and radio broadcasters.China will stick to the guidelines of "one country, two systems," "Hong Kong people governing Hong Kong," "Macao people governing Macao," and a high degree of autonomy in maintaining the long-term prosperity and stability of Hong Kong and Macao, Hu said."We will adhere to the principles of 'peaceful reunification' and 'one country, two systems,' continue to push forward the peaceful development of cross-Strait relations, ensure the basic benefits for those of the Chinese nationality, and endlessly work for the common benefit of the compatriots on both sides of the Taiwan Strait," he said.2011 was the first year of the country's 12th Five-Year Plan period (2011-2015). In the face of complicated international situations and arduous tasks in maintaining domestic reform, development and stability, Chinese people united and continued to push forward the opening up and reform drive and the socialist modernization construction, while maintaining steady and relatively fast economic growth and making progress in building a well-off society in an all-around way, he said.China was also actively engaged in international cooperation to boost the growth of the global economy and financial stability, and it was involved in resolving international and regional issues, he said.The world is currently witnessing multipolarization and globalization, and various countries are increasingly interdependent, Hu said."However, the instability and uncertainty of the world economic recovery is on the rise, international and regional hot-topic issues have cropped up one after another, and the peace and development of the world faces unprecedented opportunities and challenges," Hu said.China will stick to peace, development and cooperation, adhere to independent foreign policy, maintain world peace and promote common development, Hu said.The country will stick to the principle of mutual benefit when opening itself up, he said."We will develop friendly cooperations with all countries on the basis of the five principles of peaceful co-existence, and we will continue to actively participate in international cooperation on global issues," Hu said."I believe that as long as people from all countries make efforts hand-in-hand, the world will have a better future and the welfare of the people of all countries will improve," Hu said.An article by Hu on boosting the country's cultural development will be published in Qiu Shi (Seeking Truth), an official magazine of the Communist Party of China Central Committee, on Jan. 1.

SAN FRANCISCO, Nov. 17 (Xinhua) -- Online retail giant Amazon is working on a smartphone scheduled to be released in the fourth quarter of 2012, U.S. media reported Thursday.A note from Citigroup analyst Mark Mahaney obtained by technology news site All Things Digital said that based on the supply chain checks in Asia, Amazon is believed to launch a smartphone in the fourth quarter of 2012.According to the note, Amazon is working with manufacturer Foxconn and the device will run Texas Instruments' OMAP 4 processor. The Kindle Fire, the latest tablet introduced by the e- commerce giant, also uses OMAP processor.The analyst said the smartphone will cost Amazon between 150 and 170 U.S. dollars to build and the company could sell the handset at or near its cost rather than a 30 percent gross margin like many other smartphone manufacturers usually do.The move is expected to further intensify Amazon's rivalry with Apple and Google after the e-commerce giant had made moves on some booming businesses like tablet computer and cloud-computing service.

BEIJING, Dec. 26 (Xinhua) -- China has launched a one-year inter-agency national campaign aiming to return most street children home, the Ministry of Civil Affairs (MCA) said Monday.The MCA will lead the campaign, which is joined by the ministries of education, public security, financial, health, human resources and social security, and housing and urban-rural development, an MCA statement said."We will try our best to identify most street children in cities and send them home by the end of 2012," the statement said.Minister Li Liguo of Civil Affairs said, ministries concerned should strengthen communication and coordination, and speed up the revision of regulations on the relief of city beggars and vagrants.The MCA also urged provincial governments to set up special offices coordinating the campaign. Several provinces, such as Hebei and Yunnan, have been working on this, the statement said.Police will step up their efforts to identify and rescue street children who wander near railway stations, major tourist sites, business areas and subway stops, while civil affairs departments will assist investigation and provide shelter for homeless children, the statement said.Urban communities and neighborhoods are asked by the ministry to report homeless children to local police. Police and civil affairs departments will cooperate to ascertain the whereabouts of their parents or guardians.In home places of street children, education departments are urged to send them to schools or vocational schools, and those from needy families will have their tuition reduced or waived.Health departments are required to offer street children easy access to medical facilities in emergency cases. Hospitals listed in the campaign will treat sick street children free of charge.

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."
