WASHINGTON, Jan. 19 (Xinhua) -- New research published this week in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs.The study, led by investigators with the Ohio State University Comprehensive Cancer Center, shows that overexpression of two genes called MET and EGFR causes the deregulation of six microRNAs, and that this deregulation leads to gefitinib resistance.The findings support the development of agents that restore the levels of these microRNAs. It offers a new strategy for treating non-small cell lung cancer, which is responsible for about 85 percent of the 221,000 lung-cancer cases and 157,000 deaths that occur annually in the United States. It also suggests that measuring the expression levels of certain microRNAs -- those controlled by the MET gene -- might predict which lung-cancer cases are likely to be resistant to gefitinib.Epidermal growth factor receptor (EGFR) is frequently overexpressed in non-small cell lung cancer, and this leads to uncontrolled cell proliferation. Gefitinib selectively inhibits EGFR activation and triggers cancer cells to self-destruct by apoptosis. However, non-small cell lung cancer cells inevitably develop resistance to the drug. The study reveals how this resistance occurs."Our findings suggest that gefitinib resistance that is caused by MET overexpression is at least partly due to miRNA deregulation, " says principal investigator Carlo Croce.

ABU DHABI, Jan. 16 (Xinhua) -- Visiting Chinese Premier Wen Jiabao held talks Monday with UN Secretary General Ban Ki-moon on major international issues.During their talks, Wen said the United Nations had played an indispensable role in boosting international cooperation and coordinated actions among related parties.China supports the UN and the Secretary General to play a bigger role in international affairs and achieve greater success, he said.Chinese Premier Wen Jiabao (L) meets with UN Secretary General Ban Ki-moon (R) in Abu Dhabi, the United Arab Emirates, Jan. 16, 2012.In promoting global sustainable development, the UN and the international community needed to focus on the elimination of poverty, help developing countries properly cope with the difficulties in their drive to transfer to a green economy and provide them with support in such areas as finance, technology and capacity building, Wen said.Ban said China had played an important role in helping attain the UN Millennium Development Goals (MDGs) and settle regional hot issues.Appreciating China's support for the UN, Ban said the United Nations stood ready to advance contacts with China and make concerted efforts to safeguard world peace and promote sustainable development.They also exchanged views on the situation of West Asia and North Africa and other regional issues of common concern.Wen arrived in the capital of the United Arab Emirates Monday morning after concluding an official visit to Saudi Arabia. He visited Nepal on Saturday before flying to the Middle East. The trip will also take him to Qatar.Earlier in the day, the Chinese premier gave a keynote speech at the opening of the 5th World Future Energy Summit.

BEIJING, Oct. 3 (Xinhuanet) -- Ziqian (not his real name, but an avatar he uses online) is in Paris working on his master's degree, but he stays in close touch with his contacts in China through Sina Corp's Weibo, a micro blog platform. It was a pleasant way to keep up with acquaintances. But that all changed when Ziqian quoted a blog post from an alumnus of his alma mater, Nanjing University, on July 5. It said the school did not organize students to sing Red songs ahead of July 1, the 90th anniversary of the founding of the Communist Party of China. Ziqian suddenly found himself inundated with comments from enraged bloggers whom he didn't know. He had lost all integrity, they said.Ziqian spent the whole night arguing with one netizen who assailed him with insults. He was left feeling tired and puzzled.He said he would have given up micro-blogging altogether as "purely useless", but he uses it to stay in touch with his girlfriend.Micro-blogging has been growing rapidly, dwarfing the many other forms of social networking that came into being only three or four years ago.Famed for spreading messages almost instantly and supervising the doings of agencies and organizations, micro blogs have already won some notable battles.In March, micro-bloggers persuaded the city of Nanjing, Jiangsu province, to spare 600 old trees that were to be cut down; they also organized assistance to earthquake victims in Japan.In July, they brought the Red Cross Society of China and other philanthropies under scrutiny.But, like everything in life, there is also a downside to micro-blogging.In the Weibo-dominated virtual world, Ziqian's experience has proved a common occurrence. A 28-year-old woman, surnamed Zhang, who declined to disclose her full name, works at a TV station in Jiangsu province. She recounted her recent encounter with online abusive remarks.After watching a popular talent show, Zhang wrote half-jokingly online - without using her real name - that the program was boring and lacked imagination. Regarding herself as an "industry insider", Zhang believed her reasoning had some objective basis.Nevertheless, she was soon confronted with a wave of criticism, some of it vulgar, saying she had no appreciation for the arts."I was very depressed by the comments. It's like you get kidnapped by mainstream opinion," she said. "I lost the desire to share my views with others.""I respect the freedom of speech doctrine, and everyone is allowed to publicize his or her thoughts," Zhang wrote in a separate post. "But don't hurl random assaults at others and take for granted that whatever you say is truth."Micro blogs have also made some ordinary people famous, though not in the way they would like.Zhang Mingyi, 22, is one such person.After appearing on a dating show on Shanghai-based Dragon TV, she said her micro blog inboxes were filled every day with letters lashing out at her, because of her open enthusiasm for Japanese culture and a failed marriage.Some netizens are relentless in their resentment of her. Even her micro blog followers received warnings to stay away from the "quisling". One such message read: "Go tell her to marry a Japanese man. Don't act so shamelessly in China".Similarly, Guo Meimei, now a household name, said she was being stalked and even threatened in early September, after she bragged in a micro blog post about her wealth and - untruthfully - claimed to hold a position at the Red Cross Society of China.Bloggers launched a vast campaign boycotting a song she released online and an online game she endorsed. They satirized her plastic surgeries and gossiped about her whereabouts. In a recent interview with China Daily, Guo said the animosity she stirred was so intense that she had even considered suicide."I feel like I am an enemy of the state," she said. "The truth is that I am just a stupid girl who did something really stupid. No matter what I do, nobody wants to forgive me."Celebrities are more likely to become the targets of the word-of-mouth maelstrom online. Yang Lan, for instance, a famous TV anchorwoman, came under tremendous pressure as bloggers dug into her connections with China-Africa Hope Project, an organization set up by a prominent philanthropist, Lu Junqing, that became controversial because he empowered his 24-year-old daughter to manage the charity's substantial donated funds.Bloggers questioned whether the purpose of Lu's initiative was charity or cashing in on donators. Rumors held sway on micro blogs.A recent study from University of Michigan suggests that it is crucial that people distinguish between the truth and unfounded rumors in online social media, where vast amounts of information are easily spread across a large network by sources of unverified authority.According to Xie Gengyun, author of the 2010 China Micro Blog Annual Report and deputy dean at the Arts and Humanities Research Institute at Shanghai Jiaotong University, micro blogs can generate and spread unfounded rumors, such as the "Shanxi earthquake" and "Louis Cha's death"."Micro-bloggers are currently the better-educated people in China. But users will soon include those at the grassroots level, and the function of micro blogs will change from celebrity-watching to online socializing and venting about life's disappointments," Xie said.China's Internet, with more registered users than any other nation, is a lively forum for public opinion, said Xinhua News Agency. But "concocting rumors is itself a social malady, and the spread of rumors across the Internet presents a massive social threat."The micro blog platform tends to breed more rumors and assaults than other channels because of the limited amount of characters each post can use, according to Xiong Yihan, a sociologist with Fudan University."The word limit has made it hard to present a balanced and fair opinion. Besides, posts with extreme views are more likely to be forwarded online, because they satisfy people's thirst for the unknown," Xiong said.Xiong said Internet companies should suspend the accounts of users who spread rumors or libelous statements.

ADDIS ABABA, Oct. 22 (Xinhua) -- China on Saturday delivered portion of the first batch of emergency food assistance to Ethiopia.Wei Hongtian, Charge d'Affairs at the Chinese Embassy in Ethiopia, handed over the assistance certificate to Wondirad Mandefro, Ethiopian State Minster of Agriculture, in a ceremony held at the Office of the Ethiopian Disaster Risk Management Food Security Sector (DRMFSS) in Addis Ababa, Ethiopia.The handover was witnessed by Ahmed Shide, Ethiopian State Minister of Finance and Economic Development, and Qian Zhaogang, Economic Counselor at the Chinese Embassy in Ethiopia as well as officials and diplomats from the two countries.The charge d'affairs said the Chinese government has decided to provide Ethiopia with two batches of gratis emergency food aid valued at some 24 million U.S. dollars, as part of humanitarian assistance to the people affected by drought in the Horn of Africa region, about which the international community is concerned much.Months ago, China pledged to provide humanitarian aid to drought affected people in Ethiopia, Kenya and Djibouti.The 2011 drought in the Horn of Africa region has affected livelihoods of over 12 million people in countries of the region including Ethiopia.In this move, China has delivered large quantities of wheat to Ethiopia, and it is put in the central warehouse in Adama town, 90 km away from Addis Ababa, as the first batch of the 8,139.4 tons of wheat and 715.15 tons of rice donated by the government of China, said Ethiopian State Minister of Agriculture.According to the minister, the Chinese government has pledged around 20,000 tons of emergency food valued at 24 million dollars.Wei said China attaches great importance to the agriculture development and the food security in Africa. He said China has engaged itself in various agricultural cooperations with African countries including Ethiopia, in different channels."In the future, besides food assistance, China's agricultural cooperation with Africa will focus on technology demonstration, personnel training, infrastructure construction, promotion of agricultural production and trade, and experience sharing agriculture development," said the Charge d'Affairs.The rest portion and the other batch of the emergency food assistance pledged by China is expected to come in November and December.Wei assured that the rest batches of emergency food aid would come to Ethiopia on schedule. The Ethiopian state minister said the Chinese government is one of those donors that demonstrated its strong friendship with the Ethiopian government and its people by extending appreciable humanitarian support at critical time."The recent donation of 100, 000 U. S. dollars by a Chinese private company, Huajin Group Ltd, for food aid is a manifestation that even private companies join us in our efforts to containing problems associated with such natural disasters," said Wondirad."Despite a steady economic growth achieved these past eight years in Ethiopia that reached an average of 11 percent annually and our continued efforts to maintain and accelerate the momentum through the GTP, we are confronted by climate change induced disasters, of which drought remains the major one," said the minister."While reducing disaster risk and vulnerabilities through development interventions, the government of Ethiopia in collaboration with its partners is taking all the necessary measures towards further enhancing its early warning and response system with the view to reducing potential impacts of disasters, including that of drought enhanced preparedness and provision of timely and appropriate responses."The government of the People's Republic of China has been one of our major development partners supporting us in all these efforts," he added.The state minister commended the Chinese government and its people for standing with Ethiopia shoulder to shoulder at the critical time by donating appreciable size of emergency food aid.
