[Photo/IC] WASHINGTON -- Scientists have found that Chinese population with cardiovascular disease increased by nearly 15 percent from 1990 to 2016, but the overall death rate dropped by nearly 29 percent. The study published on Wednesday in the journal JAMA Cardiology showed that the annual number of deaths among Chinese population owing to cardiovascular disease, the top cause of death in the country, increased from 2.51 million to 3.97 million. However, the age-standardized mortality rate fell by 28.7 percent, from 431.6 per 100,000 persons in 1990 to 307.9 per 100,000 in 2016. A group of scientists led by Liu Shiwei with Chinese Center for Disease Control and Prevention examined China's national and province-level burden based on data from the Global Burden of Disease Study. They identified a substantial reduction (33.3 percent) in the cardiovascular disease burden, as measured by age-standardized Disability Adjusted of Life Years (DALY) rate, a WHO measure of overall disease burden expressed as the number of years lost due to ill-health, disability or early death. There were an estimated 93.8 million prevalent cases of cardiovascular disease during 2016 in China, more than twice that of 1990, while ischemic heart disease, ischemic stroke and hemorrhagic stroke are the top three causes of cardiovascular disease deaths in 2016, according to the study. The highest estimated prevalence rates are in Tibet, Qinghai, Hebei and Henan while the lowest rates in coastal areas like Shanghai, Hong Kong and Guangdong, according to the study. The researchers cited controlling lifestyle, reducing geographical inequity and increasing the quality of cardiovascular care the critical methods to further relieve the cardiovascular disease burden. logo braceletsrelationship braceletsorder rubber band braceletslittle rubber band braceletscustom friendship bracelets
A black wolf is photographed for the first time in the Three-River Source National Park in Qinghai province, Nov 14, 2018. [Photo/World Wide Fund for Nature] A black wolf has been photographed for the first time in the Three-River Source National Park in Qinghai province, confirming the species' existence in China, the World Wide Fund for Nature said on Wednesday. The environmental NGO said an image taken during a waterbird survey in early October was confirmed by experts this month to include a rare black wolf. The wolf had white lips and black fur, completely different from the dark-yellow and gray fur of the common gray wolf, the WWF said. The black fur in wolves is a recessive gene, common among species in North America but rare in Asia. John Mackinnon, a retired biodiversity conservation scientist, confirmed that it was a black wolf after looking at the image. The gene is recessive, which means the black wolf gets the gene only if its parents have it, Mackinnon said. The gene is very rare, so the chance (that) both carry the gene is very small. Xie Yan, a researcher at the Chinese Academy of Sciences' Institute of Zoology, said the image is of great significance to the study wolf species in China. She said experts in North America and Europe have been concerned about black wolves since the 1920s, but there are few reports documenting them in China. It shows our ecology has improved, she said. Wei Baoyu, a senior manager for the WWF Wetland Project, said the NGO hopes to carry out research on black wolves in the Three-River Source National Park Administration. make custom wristbands onlinebracelet montre silicone orangeblue silicone bracelethorizon wristbandsrubber bracelet meanings<%2fcenter>
