Nutrition in Chinese-Korean Children and Adolescents

Objective To study the nutrition habits among Chinese-Korean children and adolescents in Yanbian Autonomous Prefecture, Jilin, China. Methods Data were obtained from the Chinese National Survey on Students＇ Constitution and Health in 1995, 2000, 2005, and 2010 for Chinese-Korean children and adolescents aged 7-18 years. The number of the subjects included was 4789, 4704, 5875, and 5315, respectively. Results The rate of the occurrence of stunting showed a declining trend from 1995 to 2010 （for boys： urban, 6.3%; rural, 12.7% in 1995 and 3.5% for both in 2010. For girls： urban, 7.8%; rural, 13.4% in 1995 and 4.2% and 5.5%, respectively, in 2010）. Although the ratio of wasting did not show significant differences between the urban and rural children and adolescents in 1995, 2000, 2005, and 2010 respectively, the ratio of occurrence of overweight or obesity increased （for boys： urban, 7.3% and 1.3% in 1995, 17.6% and 12.9% in 2010; rural, 7.0% and 1.3% in 1995, 14.6% and 12.8% in 2010, respectively. For girls： urban, 8.1% and 1.0% in 1995, 17.3% and 8.6% in 2010; rural 5.7% and 0.7% in 1995, 16.4% and 7.4% in 2010, respectively）. Conclusion The ratio of malnutrition in children and adolescents in Chinese-Korean areas declined from 1995 to 2010, and the distinction in malnutrition between the urban and rural areas was negligible in 2010. Further, the ratio of overweight and obesity increased over this period.

Differences in Heart Stroke Volume between Han and Korean-Chinese Nationalities and Correlative Factors

Objective To compare the differences in stroke volume （SV） and stroke volume index （Sl） between Han and Korean-Chinese and to investigate the correlated risk factors. Methods A total of 1 647 Han and 876 Korean-Chinese aged 10-80 years were investigated. SV, SI, cardiac output, cardiac output index, heart rate （HR）, systemic vascular resistance （SVR）, systemic vascular resistance index （SVRI）, and blood pressure were measured. Results SV/SI values in Korean-Chinese were lower than those in the Han of the same sex and age. Covariance analysis showed that, apart from the effect of sex, age and body mass index （BMI）, the differences in SV and SI between the two cohorts were still significant （P〈O.O01）. Multiple regression analysis revealed that the SV difference between the two ethnicities was affected （in descending order from a strong to weak correlation） by SVR, SVRI, HR, diastolic blood pressure, mean arterial pressure, BMI, and systolic blood pressure, while the SI difference was affected by SVR, SVRI, HR, mean arterial pressure, diastolic and systolic blood pressure, and BMI. Conclusion The Fact that SV and SI in Korean-Chinese are lower than those in Han is related with higher SVR, HR and blood pressure in the Korean-Chinese.

Inheritance of growth and survival in two 9-year-old, open-pollinated progenies of an advanced breeding population of Chinese firs in southeastern China

Tree growth traits （tree height, DBH and stem volume） and survival from two 9-year-old, open-pollinated progeny tests of Chinese fir were investigated for heri- tability, genotype × environment interaction, age-age genetic correlation and selection efficiency. The 97 and 79 families planted at two sites were collected from the thirdcycle seed orchard. Individual heritability was estimated between 0.05 and 0.21 for tree height, DBH, and volume and between 0.45 and 1.0 for survival. Family heritability was between 0.20 and 1.14. Significant genotype x envi- ronment interaction was observed for the three growth traits. Type B genetic correlation was between 0.41 and 0.67 with an increasing trend as tree grows. High age-age genetic correlation was observed with correlation reaching 0.9 after age 4 for height, DBH, and volume. The genetic gains were estimated at 3.26, 3.39 and 5.98 % for tree height, DBH, and volume with 10 % selection intensity. The implication for advanced tree breeding in Chinese fir is discussed.

Energy Balance-related Behaviors Are Related to Cardiometabolic Parameters and Predict Adiposity in 8-14-year-old Overweight Chinese Children One Year Later

To identify target energy balance-related behaviors（ERBs）,baseline data from 141overweight or obese schoolchildren（aged 8-14years old）was used to predict adiposity[body mass index（BMI）and fat percentage]one year later.The ERBs included a modified Dietary Approach to Stop Hypertension diet score（DASH score）,leisure-time physical activity（PA,days/week）,and leisure screen time（minutes/day）.Several cardiometabolic variables were measured in the fasting state, including systolic blood pressure （SBP）, diastolic blood pressure （DBP）, blood glucose （GLU）, total cholesterol （TC）, triglycerides （TG）, low-density lipoprotein （LDL-C）, and high-density lipoprotein （HDL-C）.

Study on Paths of Affect Factors on Adaption to University Life of Chinese International Students in Korea —Choosing Korean Training Chinese Students as Main Investigation Objects

The purpose of this paper is to study effect factors of adaptation to university life of Chinese International Students in Korea. 374 Korean language trainees are chosen as investigation objects by means of random cluster sampling. Questionnaire data are collected by using the survey form and then paths of effect factors on adaption to university life of Korean training Chinese students in Korea are analyzed. The results indicate that Korean language proficiency, physical symptoms, loneliness, self-efficacy, acculturation stress are direct effect factors on Chinese students adapting to university life in Korea. Besides, Korean language proficiency, physical symptoms, loneliness are not only direct effect factors on self-efficacy and acculturation stress but also indirect effect factors on Chinese students adapting to university life in Korea. In order to improve ability of Korean training Chinese students adapting to university life in Korea, Korean language proficiency and self-efficacy should be improved. And, some effective interventions should be given to reducing physical symptoms, loneliness and acculturation stress.

Genomic DNA was isolated from Chinese Short-tailed Hart sheep blood. Using the polymerase chain reaction technique, PrP27-30 gene sequence was amplified from Chinese Short-tailed Han sheep genomic DNA. By recombinant DNA technology, the recombinant protein of Chinese Short-tailed Han sheep PrP27-30 was obtained. Then, using standard methodology of myeloma cell fusion, a panel of monoclonal antibodies was generated. With mAbs, scrapie in Chinese Short-tailed Han sheep was detected by immunohistochemistry assay. The recombinant protein of Chinese Short-tailed Han sheep PrP27-30 was obtained and a panel of six hybridoma cell lines secreting specific antibodies to Chinese Short-tailed Han sheep PrP27-30 related to scrapie was obtained with one fusion between myeloma Sp2/0 and spleen ceils from mice immunized with the purified recombinant protein. Four hybridoma cell lines can be used in immunohistochemistry assay for the detection of scrapie in Chinese Short-tailed Han sheep. So that the special monoclonal antibody developed in author＇s institute can be used to detect PrP^sc of scrapie in Chinese Short-tailed Han sheep by immunohistochemistry in China.

Doc Hay: A Chinese Herbalist Combating the 1918-1919 Influenza Pandemic in America

This is a story about a Chinese herbalist Ing"Doc"Hay who combated the 1918-1919 influenza pandemic in the America West.As an immigrant,he came to the States as a laborer,but he had knowledge of Chinese herbal medicine due to his family heritage.This made it possible for him to start practicing in the Chinese community in John Day,Oregon,until 1948 when he retired.During the time of the pandemic miming wild in the 1910s,he prescribed formulas aimed at flu and boiled herbal decoction,personally delivering it to a working site for those Chinese laborers as well as non-Chinese patients.None of the laborer patients treated by him died during this deadly pandemic.Due to his success and fame,his practice was booming even after the Chinese community disappeared in John Day in later years.Doc Hay is always remembered in the history of earlier development in eastern Oregon,so that the site of his practicing,Kam Wah Chung and Co.Building,is now a national historic landmark.And more importantly,he has also been remembered by Chinese herbal medicine practitioners in the United States.
