Prediction of Cold and Heat Patterns Using Anthropometric Measures Based on Machine Learning

引用

Chinese Journal of Integrative Medicine 2018年第1期24卷 16-23页

作者： Bum ju Lee jae Chul Lee Jiho Nam Jong Yeol Kim Medical Research Division Korea Institute of Oriental Medicine

Objective： To examine the association of body shape with cold and heat patterns, to determine which anthropometric measure is the best indicator for discriminating between the two patterns, and to investigate whether using a combination of measures can improve the predictive power to diagnose these patterns. Methods： Based on a total of 4,859 subjects （3,000 women and 1,859 men）, statistical analyses using binary logistic regression were performed to assess the significance of the difference and the predictive power of each anthropometric measure, and binary logistic regression and Naive Bayes with the variable selection technique were used to assess the improvement in the predictive power of the patterns using the combined measures. Results： In women, the strongest indicators for determining the cold and heat patterns among anthropometric measures were body mass index （BMI） and rib circumference; in men, the best indicator was BMI. In experiments using a combination of measures, the values of the area under the receiver operating characteristic curve in women were 0.776 by Naive Bayes and 0.772 by logistic regression, and the values in men were 0.788 by Naive Bayes and 0.779 by logistic regression. Conclusions： Individuals with a higher BMI have a tendency toward a heat pattern in both women and men. The use of a combination of anthropometric measures can slightly improve the diagnostic accuracy. Our findings can provide fundamental information for the diagnosis of cold and heat patterns based on body shape for personalized medicine.

Analysis of genetic diversity and differentiation of artificial populations of yellowhorn(Xanthoceras sorbifolium) in China using ISSR markers

引用

Journal of Forestry Research 2016年第5期27卷 1099-1104页

作者： Chanhoon An Hyunseok Lee Jeonghoon Lee Eun ju Cheong Yuhua Li jae-Seon Yi Herbal Crop Research Division National Institute of Horticultural & Herbal ScienceRural Development Administration Department of Forestry Graduate SchoolKangwon National University Forest Genetic Resources Department National Institute of Forest Science Department of Forest Resources College of Forest and Environmental SciencesKangwon National University Department of Developmental Biology College of Life ScienceNortheast Forestry University

Yellowhorn （Xanthoceras sorbifolium Bunge） is a drought-tolerant tree in the family Sapindaceae that is native to northeastern China. Its remarkably oil-rich seeds are a reliable biodiesel source. An inter simple sequence repeat （ISSR） analysis showed genetic variation among four artificial populations in China： two in Inner Mongolia （IM）, one in Liaoning （LN）, and one in Shandong （SD）. The average percentage of polymorphic loci was 81.25 % for these four populations. The Forest Farm in SD showed the highest number of effective alleles （Ne）, Shannon index （I）, and expected heterozygosity （He）, i.e., 1.598, 0.470, and 0.325, respectively, but the lowest number of alleles （Na） as 1.600. Based on an analysis of molecular variance, 23 % of the total genetic variation was found among populations, and 77 % within populations. A principal coordinate analysis revealed two groups （Group 1： Lindonglinchang, Jianping Agriculture Research Station and Forest Farm; Group 2： Jinjilinchang）. Understanding the genetic diversity among artificial yellowhorn populations in China, detected using ISSRs, will be useful for yellowhorn conservation and improvement. Additional arti-ficial and natural populations need to be included in the future for a country-wide perspective.

ntestinal Duplication Cyst Misdiagnosed as Meckel＇s Diverticulum

引用

Chinese Medical Journal 2016年第2期129卷 235-236页

作者： Yee-Suk Kim Donn-ju Kim Seung-Uk Bang jun-jae Park Department of Anesthesiology and Pain Medicine College of Medicine The Catholic University of Korea Seoul Republic of Korea Department of Surgery College of Medicine and Medical Research Institute The Chungbuk National University Chungbuk Republic of Korea

An intestinal duplication cyst is a very rare congenital anomaly, with symptoms including abdominal pain, abdominal distention, intestinal bleeding, and hematochezia. Hematochezia can be caused by ectopic gastric mucosa, although there are other causes of infantile hematochezia; hence, an intestinal duplication cyst can be misdiagnosed as bowel intussusception or Meckel＇s diverticulum. Here, a case of an intestinal duplication cyst that was misdiagnosed as Meckel＇s diverticulum is reported.
