WASHINGTON, April 11 (Xinhua) -- Taking a statin before having major elective surgery reduces potentially serious kidney complications, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology.Each year, more than 230 million major elective surgeries are performed around the world. Unfortunately, many patients who undergo major operations develop kidney injury soon after surgery, often due to decreased blood flow to the kidneys and/or the effects of inflammation.Animal studies suggest that the cholesterol-lowering drugs called statins protect the kidneys from such damage, but whether a similar benefit occurs in humans is uncertain. To investigate, Amber Molnar, University of Western Ontario, and colleagues conducted a population-based retrospective study of all older patients who underwent major elective surgery in the province of Ontario, Canada from 1995 to 2008. Surgeries included cardiac, thoracic, vascular, intra-abdominal, and retroperitoneal procedures.A total of 213,347 patients from 211 hospitals underwent major elective surgery, and 4,020 patients (1.9 percent) developed postoperative kidney injury within two weeks of surgery. A total of 1,173 patients (0.5 percent) required dialysis within two weeks of surgery, and 5,974 patients (2.8 percent) died within a month of surgery.Prior to surgery, 67,941 patients (32 percent) were taking a statin. Patients taking a statin were 20 percent less likely to develop kidney injury, need dialysis, and die compared to patients who were not taking a statin. Also, there was evidence of a dose-effect, with patients on higher potency statins having less kidney injury. In addition, statins were beneficial whether they were started greater than 90 days or less than 30 days prior to surgery."Our study suggests that statin use in older persons results in less kidney injury following major elective surgery and reduces the risk of premature death after surgery," said Molnar, adding that the results warrant further investigation with more rigorous studies, but such trials will be difficult to carry out.

LUQA, Malta, Feb. 26 (Xinhua) -- A chartered plane of China Eastern Airlines carrying 272 Chinese evacuees from Libya left Malta for Shanghai on Saturday.The Airbus A330-300 plane took off at 8:20 p.m. local time ( 1920 GMT) from the Malta International Airport, to be followed shortly by another chartered plane of China Eastern Airlines with 278 Chinese evacuees on board.The 550-strong Chinese nationals from a Chinese construction company were among a total of 2,216 people who arrived by a ship from violence-torn Libya at the Grand Harbor in Valletta, capital of Malta, on Saturday.In addition to the 2,216 Chinese nationals, the ship chartered by the Chinese embassy in Malta also carried dozens of citizens of other countries.The vessel, which was the first Maltese ship chartered by the Chinese government to evacuate Chinese nationals, left Libya's Benghazi on Friday.Maltese Deputy Prime Minister and Foreign Minister Tonio Borg, who went aboard the ship, expressed gratitude to the Chinese government for helping to evacuate some Maltese nationals from Libya.Chinese Ambassador to Malta Zhang Keyuan also thanked the Maltese government for its cooperation in the evacuation of Chinese nationals.A 19-day-old baby was among the evacuated Chinese, said a source with the Chinese embassy.China Eastern Airlines will fly four planes every day to the Mediterranean island nation from Feb. 28 to March 10, as part of all-round airborne evacuation missions aimed at taking stranded Chinese citizens back home as soon as possible, according to information from an emergency meeting of the Civil Aviation Administration of China (CAAC) in Beijing on Saturday.

TAIPEI, Jan. 29 (Xinhua) -- Nora Sun, granddaughter of Sun Yat-sen, the forerunner of China's revolution to end feudalism, died Saturday afternoon in a Taipei hospital, about one month after being injured in a car accident.Sun, 72, was severely injured in a car crash while on her way to an airport near Taipei on Jan. 1. She was in stable condition after several operations, but her condition abruptly deteriorated Saturday afternoon, according to hospital officials, without giving additional details.Sun, who spent most of her time in Shanghai, came to Taipei to attend the Flora Expo. While returning to Taoyuan International Airport near Taipei the black sedan Sun was riding in crashed head-on into an oncoming vehicle, described as a red car. Sun had planned to return to Hong Kong that day.Sun's car had been driven by a friend. The driver of the red car, who was believed to be speeding, according to police, died on the spot. Sun, her friend, and an injured passenger in the red car were immediately transported to a hospital. .Sun is the youngest daughter of Sun Fo, son of Sun Yat-sen, the leader of the 1911 Revolution that ended imperial rule in China.

LOS ANGELES, May 2 (Xinhua) -- An asteroid will fly past Earth this fall at a close approach that will allow a close-up view of one of Earth's good-sized space rocks, NASA's Jet Propulsion Laboratory (JPL) announced on Monday."On November 8, asteroid 2005 YU55 will fly past Earth and at its closest approach point will be about 325,000 kilometers away," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at the JPL in Pasadena, Los Angeles."This asteroid is about 400 meters wide -- the largest space rock we have identified that will come this close until 2028."Despite the relative proximity and size, "YU55 poses no threat of an Earth collision over, at the very least, the next 100 years, " Yeomans said in a press release."During its closest approach, its gravitational effect on the Earth will be so miniscule as to be immeasurable. It will not affect the tides or anything else.""While near-Earth objects of this size have flown within a lunar distance in the past, we did not have the foreknowledge and technology to take advantage of the opportunity," said Barbara Wilson, a scientist at JPL. "When it flies past, it should be a great opportunity for science instruments on the ground to get a good look.""The best resolution of the radar images was 7.5 meters per pixel," said JPL radar astronomer Lance Benner. "When 2005 YU55 returns this fall, we intend to image it at 4-meter resolution with our recently upgraded equipment at the Deep Space Network at Goldstone, California. Plus, the asteroid will be seven times closer. We're expecting some very detailed radar images."Asteroid 2005 YU55 was discovered in December 2005 by Robert McMillan, head of the NASA-funded Spacewatch Program at the University of Arizona, Tucson. The space rock has been in astronomers' crosshairs before.In April 2010, Mike Nolan and colleagues at the Arecibo Observatory in Puerto Rico generated some ghostly images of 2005 YU55 when the asteroid was about 2.3 million kilometers from Earth.
