BEIJING, Jan. 7 (Xinhua) -- The two-day National Financial Work Conference concluded Saturday, laying out development plans for the financial sector in the coming five years, according to a statement released after the meeting.Chinese Premier Wen Jiabao was present at the conference and delivered a keynote speech.Such a conference is held every five years. Similar meetings were held in 1997, 2002 and 2007.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."

CANBERRA, Oct. 4 (Xinhua) -- A visiting U.S. obesity expert, Kelly Brownell, on Tuesday called on Australia to make a start on taxing high-sugar soft drinks.As director of U.S. Yale University's Rudd Center for Food Policy and Obesity, Professor Brownell is in Canberra of Australia to attend the 46th Australian Psychological Society Annual Conference.He said soft drinks were a good place to start in the taxing of high-sugar foods because they were the single greatest source of added sugar in the average person's diet, had absolutely no nutritional value, were marketed aggressively and were linked with the risk for obesity and diabetes.While obesity has overtaken smoking as the leading cause of premature death and illness in Australia, he said the government should tax soft drinks in the same way it taxes cigarettes, because research showed that taxes had been the strongest influence on falling rates of consumption."We have seen how effective tobacco taxes have been in reducing rates of smoking, so there is no reason to believe such taxes wouldn't be as effective in reducing the consumption of high sugar and fat foods," Brownell, who was named by Time magazine as one of the 100 most influential people in the world, told the conference in Canberra on Tuesday. "A soft-drink tax is a good place to start. "Earlier this week, Denmark became the first country to impose a tax on food containing saturated fats, and Brownell said he completely supports Denmark's policy and that governments should act courageously to do whatever is effective in encouraging better eating habits.According to the Organisation for Economic Co-operation and Development report, Australia is ranked as one of the fattest nations in the developed world. The prevalence of obesity in Australia has more than doubled in the past 20 years, with more than 17 million Australians are overweight or obese.

BEIJING, Oct. 27 (Xinhuanet) -- Virginia M. Rometty, 54, will succeed present IBM CEO Sam Palmisano to be the next chief executive at the start of 2012, the company announced Tuesday.This is unprecedented in the New York-based company's 100-year history, because Rometty, a senior vice president of IBM, will be its first female CEO.Since joining the company three decades ago, Ms. Rometty has contributed a lot to the giant I.T. Company.After graduating from Northwestern University with an undergraduate degree in computer science, she entered the company in 1981 as a systems engineer. In virtue of outstanding performance, she was quickly promoted to management.For the following 20 years, she worked with clients in banking, insurance, and telecommunications, to name a few.In 2002, Rometty caught Palmisano's attention when she helped integrate the 3.5 billion dollar acquisition of the big business consulting firm PricewaterhouseCoopers Consulting, IBM's largest deal ever at the time.Then she became senior vice president of the group and group executive for sales, marketing and strategy in 2009. Under her leading, the business in overseas emerging markets including China, India, Brazil and several African nations, has increased sharply.New York Times reported that such markets now accounted for 23 percent of IBM.’s revenue, up from 20 percent when she took over.“Ginni got it because she deserved it,” Mr. Palmisano told the New York Times. "Ginni" is an informal first name used by her friends and colleagues.The selection of Rometty for chief executive will make her the 17th female CEO in the Fortune 500 on the following January. Other prominent women who play the same role as Rometty include Indra Nooyi of PepsiCo, Ellen J. Kullman of DuPont, Meg Whitman of Hewlett-Packard, and so on.

WASHINGTON, Oct. 3 (Xinhua) -- Overweight or obesity may put children at three times greater risk for high blood pressure than those of normal weight, according to researchers from the Regenstrief Institute and Indiana University (IU) School of Medicine.Their study will appear in the November issue of Hypertension: Journal of the American Heart Association with advance online publication on Monday.More than 1,100 healthy Indiana school children were followed for nearly five years. The researchers found that when body mass index (BMI) reached or exceeded the 85th percentile for the age and gender of the child -- designated as being overweight -- the risk of high blood pressure nearly tripled. Obesity was defined as a BMI percentile higher than 95th. BMI is a measurement of body fat calculated from weight and height.Among study participants, 14 percent of overweight or obese children were pre-hypertensive or hypertensive, compared with 5 percent of normal weight children. These findings were consistent across age, gender and race.The average age at time of study enrollment was 10.2 years. Each child was assessed approximately eight times during the course of the study. All were healthy children and none were taking medication affecting blood pressure."Higher blood pressure in childhood sets the stage for high blood pressure in adulthood," said Regenstrief Institute Investigator Wanzhu Tu, professor of biostatistics at IU School of Medicine, who led the study. "Targeted interventions are needed for these children. Even small decreases in BMI could yield major health benefits."The researcher also found that leptin, a protein hormone which is involved in body weight regulation and metabolism, was positively associated with increased blood pressure in overweight and obese children.
