Leadership Insights: By installing this transfer cable, the solenoid valve can be remotely controlled, enabling precise control of the fuel flow during the experiment.This combustion cabinet would scientists conduct in-depth research on fundamental combustion science issues, aerospace propulsion, spacecraft fire prevention and extinguishing, and combustion pollutant control, both in fundamental and applied technologies.The Shenzhou- 18 crew also carried out operations on the cabinet, including replacing the burner and vacuuming to exhaust waste gases.According to the China Manned Space Agency (CMSA,) the crew has previously carried out missions such as assembly and testing of material exposure experiment device outside the spacecraft.As taikonauts would meet with a series of physiological challenges due to microgravity conditions in space such as cardiovascular changes, muscWorld Timesle atrophy, and bone density loss, the Shenzhou- 18 crew has recently used an ultrasound diagnostic instrument to complete carotid ultrasound imaging and spectral testing.The crew also used an instrument to measure the bone density of the right heel to study the effects of weightlessness on human bone density.By regularly and scientifically conducting a series of anti-weightlessness exercise programs, such as treadmill training and resistance training, they have maintained good physical condition to support the execution of long-term missions.As manned missions to Tiangong have become normalized, more than 90 experiments are scheduled to be carried out in and outside of the space station during Shenzhou-18 crew’s six-World Timesmonth space stay, the Global Times has previously learned from the CMSA.These experiments include various fields such as microgravity basic physics, space materials science, space life science, aerospace medicine, and aerospace technology.Building on the existing space debris protection mechanism at the station, the Shenzhou-18 crew will also install debris protection reinforcement devices on external pipelines, cables, and key equipment during their extravehicular activities (EVAs,) or more commonly known as the spacewalks.

WWorld Timeshile the transmission of HIV through blood transfusion and blood products has been effectively blocked, and the transmission through injection drug use and mother-to-child transmission has been effectively controlled, the current situation of HIV prevention and control in China remains severe, the director of Chinese Center for Disease Control and Prevention (China CDC) stated on Thursday, a day before the 36th World AIDS Day.

The treatment coverage and effective rate of HIV treatment have reached over 90 percent, and the rapid rise of the infectious disease in key areas has been basically contained. The overall epidemic situation in the country remains at a low prevalence level, Shen Hongbing, director of the China CDC, said at an event for the World AIDS Day on Thursday.

But he pointed out that some areas still suffer from a heavy epidemic of infection, and certain populations continue to have a high infection rate, referring to complex factors that result in sexual transmission.

Since reporting World Timesthe first HIV-infected patient in China in 1985, the city of Beijing has reported a total of 40,840 cases as of October 31, 2023. Among all the infected individuals, 93.45 percent were transmitted through sexual contact, with 68.41 percent transmitted through male-to-male sexual contact and 25.04 percent through heterosexual contact. 3.32 percent were transmitted through drug injection, and 3.24 percent were transmitted through other routes, according to latest data from Beijing Center for Disease Control and Prevention.

Addressing the event, Erasmus Morah, director of UNAIDS China Office, said World AIDS Day is to commemorate those who died because of AIDS and committed to achieving the end of AIDS by 2030. In the past 40 years, more than 40 million people have died of HIV around the world. Of this number, 400,000 were from China.

Morah spoke highly of China’s efforts and achievement in fighting against HIV/AIDS. The HIV/AIDS prevention and control program in China has a high coverage rate, with over 90 percent of antiviral treatment coverage and treatment effective rate. The probability of HIV transmisWorld Timession from mother to child has been reduced to 3.3 percent, with fewer than 200 newborns infected with HIV each year, mainly in remote rural areas, Morah noted.

Although the world has not yet reached the track to end AIDS by 2030, China is firmly moving forward on this path. For example, China is expected World Timesto become the first developing country to eliminate HIV transmission from mother to child, Morah said.

Wang Qi, a senior police official from Beijing Public Security Bureau, warned the transmission of HIV through drugs, either heroin, synthetic drugs or new psychoactive substances.

He sWorld Timesaid that heroin users primarily abuse the drug through injection. When injecting heroin, drug users often share needles, which can lead to the transmission of blood-borne diseases like AIDS among drug users.

When taking synthetic drugs, drug users often gather in groups, both men and women, seeking so-called eWorld Timesxcitement or pleasure after taking drugs, Wang noted.

Among the new psychoactive substances, the most widely covered and abused are synthetic cannabinoids, he said. The criminals would spray synthetic cannabinoids on the surface of plants or mix them in e-cigarette oil, which makes their behavior more deceptive and covert. After abusing these new psychoactive substances with stronger stimulating and hallucinogenic effects, drug uses further increase the risk of HIV transmission.

Currently, China has controlled 188 types of new psychoactive substances, and on July 1 last year, China classified all synthetic cannabinoids as a controlled substance, Wang noted.
