BEIJING, Sept. 4 (Xinhua) -- "I never thought that I could beat the tumor," said a cancer patient in Lanzhou in northwest China's Gansu Province, adding that he is particularly grateful for heavy ion therapy, as the follow-up visit after several rounds of treatment revealed that his cancer cells had disappeared.

A research team from the Institute of Modern Physics (IMP) under the Chinese Academy of Sciences has developed the country's first medical heavy ion accelerator with independent intellectual property rights and put it into clinical application.

The successful operation of the medical equipment blazed a trail of independent innovation from the initial basic research to the final industrialization and promotion, according to the China Science Daily.

In 1993, researchers proposed to carry out basic research on heavy-ion cancer treatment during an academic conference held in Tianshui City in Gansu Province.

Cancer radiation treatments employing heavy-ion accelerators can bombard a target with high-energy electrons to kill cancer cells.

BEIJING, Sept. 6 (Xinhua) -- The International Research Center of Big Data for Sustainable Development Goals (CBAS) has released the world's first atlas of urban nighttime light remote-sensing data, providing support for the research on urban sustainable development.

BEIJING, Sept. 8 (Xinhua) -- Sales of new energy passenger cars in China surged in August, data from an industry association showed Friday.

Compared to traditional therapy such as radiation, 网络设备 heavy ion treatment is considered to have more balanced properties with less radiation on healthy cells. The treatment period is shorter and the therapy could more effectively control cancer cells.

In 2006,防水 China followed the United States, 活动房 Japan and Germany to become the fourth country to successfully carry out heavy ion clinical treatment when four cancer patients participated in preliminary clinical trials for heavy ion therapy.

Between 2006 and 2009, 设计 the research team cooperated with local hospitals to conduct preliminary clinical trial studies among 103 patients with superficial tumors and witnessed satisfactory curative effects.

The ultimate goal of heavy ion cancer therapy is to inject heavy ions into the body to treat deep tumors. Thus, 供热工程 the researchers began the preliminary clinical trial study on deep tumors in 2009.

From 2009 to 2013, there were 110 patients with deep tumors who took part in the preliminary clinical trial study, said Xiao Guoqing,毛皮加工 former head of the IMP. Meanwhile, the researchers were planning to develop a real medical heavy ion accelerator.

In 2015, China's first medical heavy ion accelerator with independent intellectual property rights rolled off the production line in Wuwei in Gansu Province. The price of the device is about one-third of similar imported ones, without any high maintenance costs.

On March 26, 2020, the accelerator was put into operation, and by the end of June 2023, more than 750 patients completed their treatments in Wuwei's heavy ion treatment center, with remarkable curative effects.

The follow-up statistics showed that the three-year local tumor control rate reached 84 percent among 46 clinical trial participants.

Similar medical heavy ion accelerators are being developed in Fujian, Zhejiang, Hubei, Jiangsu and Jilin provinces.

The researchers disclosed that they are currently working on the development of a second-generation medical heavy ion accelerator with lower power consumption.

Heavy ion therapy is highly effective in treating a wide range of solid tumors and can be used for cases that are unsuitable for surgery, not sensitive to conventional radiation, or prone to relapse following conventional radiation therapy. This includes tumors located in the central nervous system, head, neck, skull base, chest and abdomen.

The range of indications is expected to broaden through further research and the maturation of technology.  ■毛皮加工
