从原欧亚板块划出阿穆利亚微板块,并建立一个包括太平洋、北美、欧亚、鄂霍次克及菲律宾海等板块在内的6板块系统,利用地震滑移矢量,转换断层走向,洋中脊扩展速率,以及最新的GPS观测资料,采用Monte-Carlo盒子法,... 从原欧亚板块划出阿穆利亚微板块,并建立一个包括太平洋、北美、欧亚、鄂霍次克及菲律宾海等板块在内的6板块系统,利用地震滑移矢量,转换断层走向,洋中脊扩展速率,以及最新的GPS观测资料,采用Monte-Carlo盒子法,反演得到该6板块系统的欧拉运动矢量.本文得到的有关欧拉矢量为:AM-EU(60.42°N,123.25°E,0.025°/Ma),AM-OK(53.20°N,141.95°E,0.476°/Ma)以及AM-PH(50.84°N,158.13°E,1.204°/Ma),AM-EU的欧拉运动极点位于贝加尔隆起的东北及斯塔诺夫山脉的西北,并给出在贝加尔隆起有0.4-0.7mm/a的扩张,与从地质学证据得到的估计结果一致;由AM-OK及AM-PH欧拉运动矢量可以分别得到日本海东缘的6-15mm/a及日本南海地槽带的51-66mm/a收敛速率,与最新的GPS观测结果并不一致.因此,东亚北部地区存在独立的南中国微板块及其它亚尺度的微板块,可以更好地描述该地区现今板块构造的运动规律. 展开更多

AIM:To survey irritable bowel syndrome(IBS) using Rome Ⅲ criteria among Malays from the north-eastern region of Peninsular Malaysia.METHODS:A previously validated Malay language Rome Ⅲ IBS diagnostic questionnaire was used in the current study.A prospective sample of 232 Malay subjects(80% power) was initially screened.Using a stratified random sampling strategy,a total of 221 Malay subjects(112 subjects in a "full time job" and 109 subjects in "no full time job") were recruited.Subjects were visitors(friends and relatives) within the hospital compound and were representative of the local community.Red flags and psychosocial alarm symptoms were also assessed in the current study using previously translated and validated questionnaires.Subjects with IBS were sub-typed into constipation-predominant,diarrhea-predominant,mixed type and un-subtyped.Univariable and multivariable analyses were used to test for association between socioeconomic factors and presence of red flags and psychosocial alarm features among the Malays with IBS.RESULTS:IBS was present in 10.9%(24/221),red flags in 22.2%(49/221) and psychosocial alarm features in 9.0%(20/221).Red flags were more commonly reported in subjects with IBS(83.3%) than psychosocial alarm features(20.8%,P < 0.001).Subjects with IBS were older(mean age 41.4 years vs 36.9 years,P = 0.08),but no difference in gender was noted(P = 0.4).Using univariable analysis,IBS was significantly associated with a tertiary education,high individual income above RM1000,married status,exsmoker and the presence of red flags(all P < 0.05).In multiple logistic regression analysis,only the presence of red flags was significantly associated with IBS(odds ratio:0.02,95%CI:0.004-0.1,P < 0.001).The commonest IBS sub-type was mixed type(58.3%),followed by constipation-predominant(20.8%),diarrheapredominant(16.7%) and un-subtyped(4.2%).Four of 13 Malay females(30.8%) with IBS also had menstrual pain.Most subjects with IBS had at least one red flag(70.8%),12.5% had two red flags and 16.7% with no red flags.The commonest red flag was a bowel habit change in subjects > 50 years old and this was reported by 16.7% of subjects with IBS.CONCLUSION:Using the Rome Ⅲ criteria,IBS was common among ethnic Malays from the north-eastern region of Peninsular Malaysia. 展开更多

To investigate the status of mineral metabolism in people residing in huge regional centers of north-western and north-eastern parts of Russia by AES-IBP (atom-emission spectrometry with inductively bonded argon plasma), the content of 25 elements in hair samples of surveyed people was examined. The results of the study carried out in Russia's north could testify to significant deformation found in the elderly people bodies' element profiles. The pronounced deficit in such essential elements as Ca, Cr, Mg can be considered the common north-related profile typical for the elderly people from European and Asian north. In addition, age-related formation of all the elements' deficit due to their risen spending at pathologies as well as the increased need in such elements as Zn, Se, Cr, Cu, Mn. The age-related excess of arsenic proved to be typical for Magadan residents. In Anadyr, the age-related excess of lead was found, in Petrozavodsk mercury, and in Arkhangelsk--boron and aluminium. 展开更多
