A nurse checks villager Wang Funi at home in Jiaozuo, Henan province, with an all-in-one diagnostic device in March. LI JIANAN/XINHUA ZHENGZHOU - Suffering from coronary heart disease, 79-year-old Wang Funi was amazed to find out that she can have routine medical tests done at her rural home. In the past, it would take 50 minutes to travel by electric tricycle to visit the nearest county hospital, and her husband or children would have to take a break from work on the farm to accompany her. It's time-consuming. Now there's no need for the trip. All the basic tests can be done free at home, she said. With the help of a new portable all-in-one diagnostic device, Zhang Xiaozhan, a doctor in Erpuying village, Henan province, where Wang lives, conducted eight tests on her in about 20 minutes, ranging from measuring the electrical activity of her heart to checking her blood pressure. The device offers the biggest benefits for the elderly and patients with chronic diseases, reducing their need to travel long distances to hospitals and wait in long lines, Zhang said. At the start of this year, the city of Jiaozuo purchased around 600 all-in-one diagnostic devices and offered them to teams of local family doctors. Weighing just five kilograms, one of the devices can run multiple routine tests, from measuring blood pressure to urine and blood analysis. Li Zhenhui, sales manager at mobile healthcare company Garea, which provided the devices, said that the machines can do more tests if auxiliary medical equipment is connected. The company usually sends experts to train village doctors. Test results are stored as electronic files on the city's family doctor service platform as a reference for further diagnosis and treatment. Wang's team of doctors has six members. Liu Yingying, a general practitioner at the health center in Jiayingguan township, is one of them. Liu said the team has signed contracts with more than 4,000 local residents, including a priority group of more than 500 patients. Some have chronic diseases, while others are rehabilitating and need special attention, Liu said. The team needs to visit each patient in the priority group at least four times a year. It's a formidable task. The all-in-one diagnostic device can improve the quality and efficiency of our service, Liu said. Tian Qingfeng, a health management researcher at Zhengzhou University, said there is an uneven distribution of healthcare resources in China, with advanced diagnostic and treatment equipment, and the best doctors, concentrated in big cities. Technology can improve rural access to quality healthcare, Tian said.

BEIJING - Building a space station, probing Mars, setting up a lunar base and going deeper into the universe - artificial intelligence will be at the cutting edge of China's space odyssey.China is stepping up development of artificial intelligence (AI) technology to support its space programs, Zhang Duzhou, a member of the Chinese Association of Automation and the Chinese Society of Astronautics, told a space conference in Harbin, capital of Northeast China's Heilongjiang province.Back in 1995, Yang Jiachi, a leading contributor to the development of China's first satellite about half a century ago, proposed developing technology for the intelligent autonomous control of spacecraft.Experts are now developing AI technologies in visual image recognition, visual tracking, rendezvous and docking, navigation and positioning, mission planning and spacecraft fault diagnosis, said Zhang.Some Chinese spacecraft have been endowed with the preliminary ability of autonomous task-planning.For instance, Tianzhou-1, China's first cargo spacecraft launched in April 2017, accomplished autonomous fast rendezvous and docking with the Tiangong-2 space lab. The rendezvous and docking time was shortened from three days to six and a half hours thanks to AI.AI technology also aided the Chang'e-3 lunar probe, launched in 2013, to touch down softly on the Moon. The probe's lander was capable of hovering and choosing a suitable landing site on its own.However, Zhang said, China's space AI is still "weak". If AI technologies are divided into six levels, China is at level two or level three. The technology at level six, the highest level, can enable spacecraft to perform automatic reasoning and independent thinking in orbit."Our aim is to reach level six," Zhang said.AI technology is especially useful for spacecraft that are expensive, hard to repair, doing complicated tasks, deployed in a rigorous space environment, or so far from Earth that they respond to directions very slowly, said Zhang.With AI, spacecraft could acquire the abilities of self-learning, autonomous perception and planning and self-decision, thus lowering the cost of operation and increasing the quality, safety, reliability and flexibility of space missions.The development of AI will bring breakthroughs to China's space industry, he added.
