High altitude medicine in China in the 21st century Opportunities and challenges

China has the largest plateau, Qinghai-Tibet Plateau, where inhabited the most high altitude populations. Moreover, millions of people from plain areas come to the plateau for travel and work purposes and the number of the newcomers has been increasing every year. The hypoxic environment of plateau raised a series of related health issues in the new immigrants, so have created a special medical discipline- High Altitude Medicine. Over the past decades, researches on high altitude medicine have never being ceased in China, and lots of research findings have been reported. Application and practice of these achievements have greatly decreased the mobility and mortality of highaltitude diseases, however, there remained lots of questions to be elucidated. In view of this, the authors were granted a special project from the National Health and Family Planning Commission of China, and conducted a multi-center, prospective, on-scene high altitude medicine study for the acute mountain sickness. Some innovative findings were achieved, and the parameters for diagnosis and application conditions were proposed. Furthermore, the different diagnoses and treatment effects were compared, and a more standardized, reasonable scheme was drawn up. Regarding the unbalanced medical resources in the vast high altitude area, an application system for the public and the army has been established. In the 21 st century, innovations in China and novel research approaches have provided great opportunities for the development of high altitude medicine. It is believed that the researchers in China are able to catch the opportunities and address the challenges.     

Relationship between excessive erythrocytosis and acute mountain sickness: A field study

Background: Alterations in hematology, especially erythroid changes, may be involved in acute mountain sickness(AMS) at high altitude. This study aimed to identify the relationship between excessive erythrocytosis and AMS following different durations of high-altitude exposure.Methods: A total of 692 healthy young Chinese men were recruited for the study in June and July of 2012 and were divided into the following five groups: I) the 24-h group(24 hours after arrival at Lhasa, 3,700 m, n=261); II) the 7-d group(exposed at Lhasa, 3,700 m for seven days, n=99); III) the re-exposure group(re-exposed at Yang Bajing, 4,400 m for seven days after >1 year of acclimation at 3,700 m, n=94); IV) the acclimated group(>1 year of acclimation at 3,700 m, Lhasa, n=42); and V) the sea-level control(control group, Chengdu, n=196). Case report forms were used to record the subjects’ demographic information and AMS-related symptoms. All of the subjects underwent routine blood tests.Results: The red blood cell(RBC) count fell slightly but was not significant upon acute exposure to high altitude, whereas the hemoglobin concentration([Hb]) increased significantly. After high-altitude re-exposure, both of the [Hb] and RBC count showed significant increases. The incidence of AMS was 65.1%, 26.3% and 51.1%, respectively in the 24-h, 7-d and re-exposure groups. The [Hb](P=0.024) and hematocrit(P=0.017) were greater in the AMS+ individuals than in the AMS– individuals in 7-d group. A correlation analysis revealed that the [Hb] and hematocrit were closely related with AMS score in 7-d and re-exposure groups, while the RBC showed a correlation with AMS score only in the re-exposure group. The AMS incidence was lowest when the [Hb] was between 140 and 160 g/L in the 24-h and 7-d groups.Conclusions: AMS is associated with both [Hb] and excessive erythrocytosis. Additionally, our findings indicate the existence of an optimal [Hb] for preventing AMS.     

Smoking is associated with the incidence of AMS: A large-sample cohort study

Background: In recent years, the number of people visiting high altitudes has increased. After rapidly ascending to a high altitude, some of these individuals, who reside on plains or other areas of low altitude, have suffered from acute mountain sickness(AMS). Smoking interferes with the body’s oxygen metabolism, but research about the relationship between smoking and AMS has yielded controversial results.Methods: We collected demographic data, conducted a smoking history and performed physical examinations on 2,000 potential study participants, at sea level. Blood pressure(BP) and pulse oxygen saturation(SpO2) were measured for only some of the patients due to time and manpower limitations. We ultimately recruited 520 smokers and 450 nonsmokers according to the inclusion and exclusion criteria of our study. Following acute high-altitude exposure, we examined their Lake Louise Symptom(LLS) scores, BP, HR and SpO2; however, cerebral blood flow(CBF) was measured for only some of the subjects due to limited time, manpower and equipment.Results: Both the incidence of AMS and Lake Louise Symptom(LLS) scores were lower in smokers than in nonsmokers. Comparing AMS-related symptoms between nonsmokers and smokers, the incidence and severity of headaches and the incidence of sleep difficulties were lower in smokers than in nonsmokers. The incidences of both cough and mental status change were higher in smokers than in nonsmokers; blood pressure, HR and cerebral blood flow velocity were lower in smokers than in nonsmokers.Conclusions: Our findings suggest that the incidence of AMS is lower in the smoking group, possibly related to a retardation of cerebral blood flow and a relief of AMS-related symptoms, such as headache.     

Correlations between self-reported symptoms and psychosocial factors of perpetrators with domestic violence in China: a population-based sample

Background  Domestic violence (DV) is not only a devastating societal problem, but also a severe medical and mental health problem worldwide. Our previous study has shown that perpetrators were with higher prevalence of self-reported symptoms than that of controls. This study based on our former large scale population-based samples is aimed to further explore the correlations between the symptoms and psychosocial factors of the perpetrators with DV. It was helpful to provide some insight into possible strategies for clinicians to reduce the symptoms of the perpetrators with DV in China.

Methods  From our former population-based epidemiological samples, 1098 households with a history of DV in preceding year, 318 perpetrators with DV were randomly selected. Face-to-face interviews were conducted. Symptom Checklist-90 (SCL-90) was administrated to check and classify the symptoms of perpetrators, Eysenck’s personality questionnaire (EPQ), trait coping style questionnaire (TCSQ), life events scale (LES) and social supporting rating scale (SSRS) were administrated to evaluate the psychosocial factors of perpetrators. The correlation analysis was used to analyze the relationships between the symptoms and psychosocial factors of perpetrators of DV.

Results  The global and all subscale scores of SCL-90 were significantly positively correlated with EPQ-N, negative TCSQ and negative LES scores (P <0.01). The global score of SCL-90 was negatively correlated with both objective and subjective SSRS (P <0.01). The negative LES and negative TCSQ were significantly positively correlated with EPQ-N (P <0.01). Negative TCSQ was significantly positively correlated with negative LES and negatively correlated with subjective SSRS (P <0.01).

Conclusions  The self-reported symptoms of perpetrators with DV were strongly correlated with their psychosocial factors, such as the neurotic personality, negative coping style, more negative life events and less subjective social supports. It suggested bio-psycho-socially oriented interventions were necessary to buffer the symptoms of perpetrators with DV.

Correlation between blood pressure changes and AMS,sleeping quality and exercise upon high-altitude exposure in young Chinese men

Background: Excessive elevation of arterial blood pressure(BP) at high altitude can be detrimental to our health due to acute mountain sickness(AMS) or some AMS symptoms. This prospective and observational study aimed to elucidate blood pressure changes induced by exposure to high-altitude hypoxia and the relationships of these changes with AMS prevalence, AMS severity, sleep quality and exercise condition in healthy young men.Methods: A prospective observational study was performed in 931 male young adults exposed to high altitude at 3,700 m(Lhasa) from low altitude(LA, 500 m). Blood pressure measurement and AMS symptom questionnaires were performed at LA and on day 1, 3, 5, and 7 of exposure to high altitude. Lake Louise criteria were used to diagnose AMS. Likewise, the Athens Insomnia Scale(AIS) and the Epworth Sleepiness Scale(ESS) were filled out at LA and on day 1, 3, and 7 of exposure to high altitude.Results: After acute exposure to 3,700 m, diastolic blood pressure(DBP) and mean arterial blood pressure(MABP) rose gradually and continually(P<0.05). Analysis showed a relationship with AMS for only MABP(P<0.05) but not for SBP and DBP(P>0.05). Poor sleeping quality was generally associated with higher SBP or DBP at high altitude, although inconsistent results were obtained at different time(P<0.05). SBP and Pulse BP increased noticeably after high-altitude exercise(P<0.05).Conclusions: Our data demonstrate notable blood pressure changes under exposure to different high-altitude conditions: 1) BP increased over time. 2) Higher BP generally accompanied poor sleeping quality and higher incidence of AMS. 3) SBP and Pulse BP were higher after high-altitude exercise. Therefore, we should put more effort into monitoring BP after exposure to high altitude in order to guard against excessive increases in BP.
