China has granted marketing approval of its first drug for the prevention of acute mountain sickness, filling the long-standing gap in the domestic market where no such medications had been available, Science and Technology Daily reported on Tuesday.
The National Medical Products Administration (NMPA) has approved the marketing of acetazolamide sustained-release capsules, the report said. As the first specialized drug in China indicated for preventing of acute mountain sickness, its approval marks the end of the country's lack of dedicated preventive treatment for altitude illness. 
By inhibiting the activity of carbonic anhydrase, acetazolamide promotes the renal excretion of bicarbonate, corrects respiratory alkalosis caused by hypoxia at high altitudes, thereby regulating acid-base balance, optimizing respiratory status, elevating blood oxygen levels, and reducing the risk of onset at the source. 
In contrast to health products that only provide auxiliary regulatory effects, this medication has been validated through stringent clinical trials and stands as a specialized drug approved by the NMPA with a clear indication for prevention, said the report.
Led by principal investigator is Luobu Gesang, a deputy dean of the People's Hospital of Xizang Autonomous Region, the clinical trial was designed by his team and has yielded critical evidence to inform prevention strategies for altitude sickness that are specifically adapted to Chinese and Asian populations. 
"Previously, although acetazolamide had already been used internationally for the prevention of acute mountain sickness, China had long lacked an NMPA-approved acetazolamide formulation supported by rigorous clinical trials. Furthermore, the existing international formulations were short-acting tablets requiring multiple daily doses, and no drugs with the relevant indication were available on the domestic market for an extended period," said Luobu Gesang.
The sustained-release capsule approved this time not only fills this critical gap but also optimizes the dosage form, providing more reliable and convenient medication protection for the physical health and life safety of people entering high-altitude areas, he added.
Clinical trials showed that, compared with the placebo group, the incidence of acute mountain sickness in the medication group was significantly reduced, with the incidence of moderate-to-severe acute mountain sickness decreasing by 14.6 percent, according to the report.
Related research has been published in the international flagship journal of high-altitude medicine, High Altitude Medicine & Biology.

(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.

SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.
