BEIJING, Nov. 20 (Xinhua) -- Chinese Vice Premier Li Keqiang visited HIV/AIDS medical personnel, volunteers of non-government organizations (NGOs), and people living with HIV ahead of the World AIDS Day which falls on Dec. 1.In the voluntary testing clinic of the Beijing Diseases Prevention and Control Center (CDC), Li said counseling and testing are crucial to the early detection and early treatment of HIV/AIDS, and encouraged the clinic staff to work hard on the very front-line of HIV prevention and control.While visiting NGOs situated in the Beijing CDC, Li greeted people living with HIV and volunteers, shaking hands with them. He recognized the role of NGOs in keeping the disease at bay, particularly in terms of HIV/ AIDS awareness education and intervention.Chinese Vice Premier Li Keqiang (C) talks with a HIV/AIDS medical personnel as he visits the voluntary testing clinic of the Beijing Diseases Prevention and Control Center (CDC), in Beijing, China, Nov. 18, 2011.Li said HIV prevention and control is a systemic project that takes the entire society to carry out, calling for establishing a mechanism to involve "social forces" into HIV prevention and control.Li asked health authorities at all levels to keep close contact with HIV-related NGOs, providing assistance needed to these organizations and their volunteers."Care, respect and assistance are the best pain relievers for people living with HIV," Li said, calling upon the entire society to pay greater attention and care to this group of people.

BEIJING, Jan. 26 (Xinhua) -- China will firmly stand together with African countries while unswervingly pushing forward Sino-African strategic partnership, no matter how the international environment changes, said Chinese Vice Foreign Minister Zhai Jun Thursday.Zhai made the remarks in a signed article on top Chinese political advisor Jia Qinglin's upcoming visit to Africa.Africa still faced enormous challenges against the backdrop of simmering global finance crisis, and turbulence encountered by several countries in western Asia and northern Africa, which dealt a blow to Africa's peace, stability and development, Zhai said, adding that some outside forces' intervention into Africa's internal affairs impeded the integration process among African countries.Within this context, there is stronger demand of African countries for stability, development, solidarity and independence, he said.The international community should pay more attention to Africa's voice and problems, respect its opinions, accommodate its concerns, protect peace, stability and development in Africa, and support Africa's independent settlement of issues in its own region, Zhai said.He said Jia's visit, first foreign trip paid by Chinese leaders in the Chinese Lunar New Year, will be of great significance in deepening Sino-African ties and cementing the solidarity and cooperation among developing countries, Zhai said.Jia will declare China's determination on developing Sino-African ties during the trip, he said.Enhancing solidarity and cooperation with Africa constitutes an important part of China's diplomacy, and will be the long-term strategic choice firmly pursued by China, Zhai said.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

BEIJING, Nov. 28 (Xinhuanet) -- The U.S. FBI and police in the Philippines have arrested four alleged hackers in Manila with connections to a terrorist group in Saudi Arabia, according to media reports Monday.The four who were arrested last Wednesday hacked into AT&T Inc.'s phone systems as part of a plan to funnel money to a Saudi-based terror group, the reports said.The hackers, according to the investigators, worked for a group that helped finance a deadly 2008 terrorist attack in Mumbai, India.Investigators also said the hacking cost AT&T around 2 million U.S. dollars. And an AT&T representative told Reuters that it "ended up writing off some fraudulent charges that appeared on customer bills" but did not comment on the 2 million dollars figure."AT&T and its network were neither targeted nor breached by the hackers," AT&T spokeswoman Jan Rasmussen said. "AT&T only assisted law enforcement in the investigation that led to the arrest of a group of hackers."

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.
