JINAN, Feb. 3 (Xinhua) -- Chinese Premier Wen Jiabao on Wednesday and Thursday visited drought-hit villages and ordered all-out efforts to combat the dry spell while celebrating the Chinese New Year with local people.When visiting Jiaxiang County and Qufu City in east China's Shandong Province, Wen inspected cornfields and reservoirs to assess the drought's impact.The drought, which began in October, has hit the southwest parts of Shandong hardest."It's hard to know when it will rain. We must prepare for the worst and do our best to combat the drought to ensure a good harvest," Wen said while visiting a reservoir in Qufu.Wen made the remarks Wednesday afternoon after learning the reservoir was holding a volume of water 8 million cubic meters less than normal.He told officials accompanying him any drought-caused reduction in grain output may undermine the government's top priority for 2011: the stabilization of prices.Officials at all levels must work to combat the drought, Wen added.China's central authorities last week announced an ambitious water conservancy project development plan, to raise China's ability to control flooding and drought.Under the plan, the average annual government spending on such projects will double the 2010 level."The drought affects agricultural output, which is related to the nation's food security and the income of rural people. I worry about it," Wen told a local farmer Wednesday morning.In the evening, Wen joined Liu Xianglun, 77, and his family at their house to make dumplings to eat to welcome the Chinese New Year.Before visiting Shandong, Wen visited farmers and workers in Dabieshan Mountain area, an old revolutionary base in east China's Anhui Province.The Spring Festival, China's Lunar New Year, falls on Thursday.

BEIJING, May 25 (Xinhua) -- A researcher with the Chinese Academy of Agricultural Sciences (CAAS) said Wednesday that plant hormones, if used properly, are not a risk to human health."Irregular use of plant growth substances may cause plants to grow excessively fast or affect the taste, but will not cause harm to human health," Ye Zhihua said in an interview with Xinhua.His remarks come after media reports in China about "exploding watermelons," caused by the excessive use of phytohormone, have aroused public concern over the safety of hormones that stimulate plant growth.Ye said plant hormones used to promote growth have the same or similar effects as natural plant hormones, and fruit and vegetables sold at the market carried limited residue of the hormones.More than 100 types of plant hormones, such as ethephon and gibberellin acid, are used in agriculture and forestry sectors around the world, Ye said, adding 38 types of plant hormones have been registered in China.For example, seven plant hormones including thidiazuron and nucleotide are approved for use on cucumbers in China. The purpose is to stimulate the growth of female flowers and increase fruit yields, Ye said.Ye added that China places plant hormones in the category of pesticides control, which means the hormones are subject to strict management from production to utilization.

BEIJING, Feb. 7 (Xinhua) -- China on Monday called for calmness and restraint from both Cambodia and Thailand to prevent the escalation of border conflicts between the two southeast Asian countries."Both Cambodia and Thailand are China's friendly neighbors. China hopes that the two nations exercise calmness and restraint, resolve disputes through consultation, and prevent the situation from escalation," Foreign Ministry spokesman Hong Lei said.The latest fighting between Cambodian and Thai troops in their age-old territorial dispute erupted at the border region Friday afternoon and entered the fourth consecutive day Monday.

WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.

BEIJING, April 10 (Xinhua) -- Many children in the U.S. live in poverty and their physical and mental health is not ensured as nearly one in four children struggles with hunger, according to a report on the U.S. human rights record released by China on Sunday.The Human Rights Record of the United States in 2010 was released by the Information Office of China's State Council in response to the country reports on Human Rights Practices for 2010 issued by the U.S. Department of State.The poverty rate increased for children younger than 18 to 20.7 percent in 2009, up 1.7 percentage points from that in 2008, the report quoted figures from the U.S. Census Bureau as saying.The report pointed out that violence against children is very severe in the country, citing figures from the official website of Love Our Children USA that every year over three million children are victims of violence reportedly and the actual number is three times greater.More than 93,000 children are currently incarcerated in the United States, and between 75 and 93 percent of children have experienced at least one traumatic experience, including sexual abuse and neglect, the report said.According to the report, pornographic content is rampant on the Internet and severely harms American children as seven in 10 children have accidentally accessed pornography on the Internet and one in three has done so intentionally.
