许多精神病专家开始认识并承认患精神病的少数民族可受助于文化支柱系统(CultralSupport Systems)以及传统医术。定居西方社会的大多数苗族精神病者,在丰富的传统医术中,取其一种或多种疗法都将受益匪浅。一些精神病专家希望能帮助他们的苗族患者找到适合自己的传统疗法。但就苗族个人来说,什么疗法是适宜的以及在苗族社会对患者用什么方法是可行的,对这些背景知识他们缺乏了解。本文之目的首先是要读者熟悉苗族对心理健康的传统看法;第二个目的是介绍多种苗族传统医术以及解释它们怎样帮助某些精神病人;第三本文将证明那些同时使用西方和苗族疗法的苗族患者,比只用其中一种疗法的会取得更好的疗效。

BACKGROUND Patients discharged after hospitalization for acute heart failure(AHF) are frequently readmitted due to an incomplete decongestion, which is difficult to assess clinically. Recently, it has been shown that the use of a highly sensitive,non-invasive device measuring lung impedance(LI) reduces hospitalizations for heart failure(HF); it has also been shown that this device reduces the cardiovascular and all-cause mortality of stable HF patients when used in longterm out-patient follow-ups. the aim of these case series is to demonstrate the potential additive role of non-invasive home LI monitoring in the early postdischarge *** SUMMARY We present a case series of three patients who had performed daily LI measurements at home using the edema guard monitor(EGM) during 30 d after an episode of AHF. All patients had a history of chronic ischemic HF with a reduced ejection fraction and were hospitalized for 6–17 d. LI measurements were successfully made at home by patients with the help of their caregivers. the patients were carefully followed up by HF specialists who reacted to the values of LI measurements, blood pressure, heart rate and clinical symptoms. LI reduction was a more frequent trigger to medication adjustments compared to changes in symptoms or vital signs. Besides, LI dynamics closely tracked the use and dose of *** Our case series suggests non-invasive home LI monitoring with EGM to be a reliable and potentially useful tool for the early detection of congestion or dehydration and thus for the further successful stabilization of a HF patient after a worsening episode.

Background: Given the low levels of physical activity(PA) among adolescent girls in the US, there is a need to identify tools to motivate increased PA. Although there is limited evidence that adolescents transfer PA from one context to another, exergames(i.e., video games that require gross motor activity) may act as a gateway to promote overall PA outside game play. the purpose of this study was to examine potential transfer effects(i.e., influences on external behaviors and psychological constructs) of a 12-week exergaming intervention on adolescent girls' PA, screen time,and self-efficacy toward PA, as well as the intrinsic motivation of ***: Participants were 37 girls aged 14–18 years(65% African American, 35% white) who were overweight or obese(body mass index ≥ 85 th percentile) and were recruited from the community via school, physicians, news media, and social media websites. Adolescents were randomly assigned to a 12-week group exergaming intervention(thirty-six 60 min sessions of group-based dance exergaming in a research laboratory using Kinect for Xbox360(Microsoft Corporation, Redmond, WA, USA)) or to a no-treatment control group. Outcome variables included objectively measured PA(total) and self-reported leisure-time PA(discretionary time only) 1 week before vs. 1 week after the intervention; selected type and intensity of PA when placed in a gym setting for 30 min("cardio free choice"); screen time; self-efficacy toward PA; and intrinsic motivation toward ***: Attendance at the exergaming sessions was high(80%). Compared with the control group, the intervention group self-reported an increase in PA(p = 0.035) and fewer hours watching television or videos(p = 0.01) after the intervention, but there were no significant differences in sedentary, light, moderate, or vigorous PA measured by accelerometry. the intervention group significantly improved self-efficacy toward PA(p = 0.028). the intervention group highly rated intri

the monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. the mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem.
