Objective： To determine the prevalence of the use of acupuncture treatment for acute low back pain （LBP） among acupuncture practitioners, and investigate acupuncture practitioners＇ perceptions on the effectiveness of this treatment modality and the costs associated with its use in Canada. Methods： A questionnaire designed to achieve our objectives was distributed to all 285 members in the Ontario chapter of the Acupuncture Foundation of Canada （AFC） in September of 1996. Only responses from physicians and physiotherapists were included in the analysis. Results： Of the 281 eligible physicians and physiotherapists, 197 completed the survey （response rate of 70.1%）. 45.0% of the respondents were physicians and 55.0% of them were physiotherapists. 87.0% of the respondents had used acupuncture for the treatment of acute LBP in the past, 66.0% of them were using it at the time of the survey and 87.0% said they would continue to use it in the future. 83.0% of the respondents perceived acupuncture to be effective for acute LBP and 60.0% of them believed that treating acute LBP with acupuncture will prevent the development of chronic LBE The average cost per treatment was $28 and the average time of treatments thought to be necessary to treat acute LBP was 5.7. Conclusions： The results showed that the majority of the respondents had a positive and favorable outlook towards using acupuncture for the treatment of acute LBP. They frequently used acupuncture for treating this condition in their practice and an overwhelming majority perceived acupuncture to be effective for treating acute LBP. In addition, over half of the respondents believed that acupuncture treatment would prevent the progression of acute LBE Although the acupuncture practitioners surveyed in this study perceived acupuncture to be an effective treatment for acute LBP, quantitative data from high quality research are needed to validate these perceptions.

Summaries and Recommendations of the Global Impression Method

引用

Journal of Acupuncture and Tuina Science 2009年第5期7卷 296-302页

作者： kien trinh McMaster University

With the increase in the number of acupuncture clinical trials, systematic reviews are used to summarize key results across many disciplines. Meta-analysis is a popular method for synthesizing evidence as it provides a succinct way of summarizing evidence quantitatively. Due to clinical heterogeneity, however, it is not always possible to use meta-analysis. Instead, a qualitative method is used. The purpose of this paper is to summary the findings of current research on the Global Impression Method （GIM）; a method used to synthesize the results of clinically heterogeneous randomized controlled trial （RCT） in systematic reviews. The results indicate that there is moderate to substantial intra-rater and inter-rater agreement when judging the results of the forest plots using a global impression and simplified version of the best evidence synthesis （BES） method when compared to the results of meta-analyses. Thus, the GIM can be used for researchers to synthesize results of RCT. The quality of the individual study can be taken into consideration after this process to determine a more precise strength of the evidence, therefore, GIM worthy to be used in acupuncture or other studies.

Tracer Diffusion Mechanism in Amorphous Co-based Alloys

引用

材料科学与工程（中英文B版） 2011年第5期1卷 575-583页

作者： Pham Huu kien trinh Van Mung Pham Khac Hung Hoang Van Hue Hanoi University of Science and Technology Hanoi Viet Nam Tay Nguyen University Buon Ma Thuot Viet Nam

Tracer diffusion mechanism in amorphous Co and Co81.5B18.5 solids is studied using the statistic relaxation model containing 2 × 105 atoms. It was found a large number of microscopic bubbles which could break up and leads to diffusion. A new diffusion mechanism via the microscopic bubbles is proposed and the diffusion coefficient determined in term of this mechanism is in reasonable agreement with experimental data. The decrease in diffusion coefficient upon thermal annealing observed experimentally for most amorphous alloys is interpreted as a result of reduced number of microscopic bubbles.

This paper presents the quantitative assessment results of rainwater supply to groundwater in Cai Phan Rang River basin, Ninh Thuan province, Vietnam. In order to obtain the results, the authors developed two experimental areas with 10 wells which were monitored in one year to assess the infiltration supply of rainwater to groundwater. The results of this research assessed the amount of rainwater infiltrates into groundwater varies from 307.16-314.98 tam·year^-1, average is 311 mm·year^-1. The findings are significant in terms of science which identify sources of groundwater storage from the infiltration supply of rainwater. The findings are also practical in suggesting measures to reserve groundwater for the purpose of socio-economic development in the study area.
