Yushu is in Qinghai-Tibet plateau, an average altitude of 4000 m. The medical staff is limited in Yushu. Zhongshan ophthalmic center, sun yat-sen university in Yushu blindness project has lasted many years. Some medical staff who arrived at Yushu will have a plateau response. The high altitude
About 100 million individuals reside at high altitude (>2500m) worldwide, with the largest populations of highlanders being found in South America (Andean), central Asia (Tibetan and Sherpa) and East Africa (Ethiopian). Despite unique adaptations to hypoxia in these populations, chronic mountain
RIC is induced by short-term insulting blood-flow of nonvital distant organs intermittently and has been proved to be effective in ischemic stroke and myocardial infarction(MI).The possible mechanisms of RIC protection is complicated.RIC leads to local ischemia and hypoxia and has been demonstrated
INTRODUCTION: Short-term space flight induces an alteration of circulating blood volumes, termed "space flight anemia" and characterized by a decrease in total red blood cell volume (RCV) and plasma volume (PV). This haematological alteration is likely to persist during a long-term space mission and
A patent foramen ovale (PFO) is present in ~30% of the general population. The PFO has historically been considered to be trivial. However, recent work by the investigator's group and others has identified that, compared to individuals without a PFO, those with a PFO have a higher core body
According to the British Thoracic Society (BTS) recommendations regarding pre-flight evaluation in patients with pulmonary disease, pre-flight arterial oxygen saturation or lung function tests do not discriminate sufficiently between those who need supplemental oxygen during flights, and those who
The study will investigate digoxin to inhibit the hypoxic response in congenital erythrocytosis due to germ line mutations that result in up-regulated hypoxia sensing. These forms of congenital erythrocytosis, characterized by augmented levels of hypoxia inducible factor (HIF)-1 and/or HIF-2, are
The exact mechanisms by which AMS develops remains poorly understood. Interestingly, brain and spinal cord swelling due to low oxygen levels can also occur in the period following surgery to treat thoracic and abdominal aortic aneurysms, dangerous swellings of the major blood vessel in the body.
The primary endpoint of this research study is to prove safety in healthy subjects breathing humidified hypoxic inspiratory gas mixture for 5 days.
The secondary endpoint of our study is to describe the physiological and biochemical changes during the 5-day hypoxic period and the 2 days after return
Compound danshen dripping pills is mainly used for the treatment and prevention of coronary heart disease and high-risk groups ,consists of Danshen (Radix Salviae Miltiorrhizae), Sanqi (Radix Notoginseng) and borneol.Danshen is the main drug efficacy of stasis, nourishing the nerves.Pharmacological
Oxygen is necessary to sustain human life and is used for energy production by oxidation in the mitochondria. Application of oxygen not only increases saturation in the patient's blood, but also has various secondary effects. It is therefore used to treat diseases that impairs body's ability to take
