ABSTRACT
[Abstract] Objective To explore the body index and typing characteristics of Xibe nationality. Methods According to Anthropomatric Methods, height, chest circumference, sitting height, shoulder width, pelvic width and body mass morphological indexes were collected from 588 Xibe people in Yili area and 420 Xibe people over 18 years old in Shenyang area. After data collation, body index and typing were calculated and analyzed statistically. Results Except for Xibe male stature-shoulder breadth index and Caup’ s index in Yili area and female stature-shoulder breadth index in Shenyang area, there were differences among age groups in other indexes (P < 0. 05). Except for male stature-chest circumference index, stature-crista iliaca index, female stature-chest circumference index, stature-sitting height index, Manouvrier’s skelic index, there were differences among regions (P<0. 05). The adult body shape of Xibe nationality was mainly of wide chest, wide shoulder, long trunk, wide pelvis, medium leg and sub-long leg (male), sub-short leg and medium leg (female), and overweight. Conclusion There are regional and age differences in the body index and typing of Xibe adults. Compared with other ethnic minorities, Xibe nationality’s stature-chest circumference index, stature-shoulder breadth index, stature-crista iliaca index, Caup’s index are at a higher level. The proportion of legs and body of Xibe nationality is in the middle level, while the proportion of trunk is slightly shorter for men and slightly longer for women.
ABSTRACT
Objective To explore the characteristics and regularity of somatotype development of Hui adolescents in Nanyang area. Methods The Heath-Carter body type method was used to evaluate the body type of 1357 Hui adolescents in Nanyang area. Results The height and weight of adolescents aged 7-18 increased with age. Except for the 8- year-old group, the body fat rate of girls in other age groups was greater than that of boys. The average somatotype of Hui boys in Nanyang area was mesomorphic endomorph ( 5. 3-4. 0-3. 4 ), while the average somatotype of Hui girls was ectomorphic endomorph ( 5. 0-2. 5-3. 3). Both boys and girls were endomorph mainly ( boys 40. 0%, girls 29. 0% ). Except for the 17-year-old group, in terms of endomorphy, boys was greater than that of girls in other age groups; as for mesomorphy, boys was greater than that of girls in all age groups ; as far as ectomorphy was concerned, girls was greater than boys in the 7-13 years old groups, and in thel4-18 years old groups boys was greater than girls. Conclusion The Hui girls in Nanyang area are thinner and less subcutaneous fat than the boys. Compared with the girls, the Hui boys ' bodies have higher linear shape and more fullness. The Hui adolescents in Nanyang area have more body fat, which may be related to their unreasonable diet and living habits.
ABSTRACT
Objective To understand the distribution characteristics of body fat content and basal metabolic rate among Xibo adults in Xinjiang and to explore the correlation between them. Methods The people aged between 35 and 70 were randomly selected to be the research object, and a total of 536 people (263 males and 273 females) were selected for the study. Subcutaneous fat, visceral fat, weight, stature, defat weight, body fat rate and basal metabolic rate were measured using the body composition analyzer. The correlation between body fat content and basal metabolic rate was studied by regression analysis, and regression equation coefficient was calculated. Results There were statistically significant in total fat, defate body weight and body fat percentage (P<0. 05) of different aged Xibo adults in Xinjiang, except for male visceral fat and female subcutaneous fat. There were statistically significant subcutaneous fat, total fat and body fat percentage(P<0. 05) between the sexes, except for visceral fat. The visceral fat content among Xibo adults in Xinjiang was negatively correlated with basal metabolic rate (P<0. 05). Conclusion Body lipid distribution is differences in different aged and gender among Xibo adults in Xinjiang. There is a negative correlation between visceral fat and basal metabolic rate.
ABSTRACT
Objective To analyze the changes of serum biochemical indexes with age and gender in Xinjiang Uygur and Kazak populations, and to compare the differences of serum biochemical indexes between Xinjiang Uygur and Kazak populations in gender and age. Methods Totally 511 Xinjiang Uygur and Kazak healthy adults were randomly selected from a hospital in Xinjiang Uygur autonomous region for normal physical examination, including 252 and 259 Xinjiang Uygur and Kazak healthy adults. Serum biochemical indexes were detected by CX-7 automatic biochemical analyzer produced by Beckman, USA, and statistical analysis was conducted by variance analysis, t test, correlation analysis and chi-square test. Results Xinjiang Uygur nationality and Kazak serum biochemical indexes for the male and the female, including glutamic-pyruvic transaminase (GPT), direct bilirubin (DBil), uric acid (UA), creatinine (Cre) and urea (Ure), glucose (Glu), total bilirubin(TBil), cystatin C(Cys-C) increased with the growth of the age, and sex between different age groups were statistically significant (P 0. 05). There were statistically significant differences in Glu, TG, TC, LDL and HDL between Xinjiang Uygur and Kazak people of the same gender and age group (P < 0. 05). Conclusion The serum biochemical indexes of Uygur and Kazak in Xinjiang are different in different ages and genders. The Glu and lipid levels of Uygur nationality in Xinjiang are different from those of Kazak nationality.
ABSTRACT
Objective To investigate the 20 facial morphological characteristics of Xibo ethnicity adults in Chabchar in Xinjiang, and to explore the causes of the features, so as to provide basic data for the basic study of minority anthropology. Methods A random sampling method was used to determine 677 Xibo ethnicity adults, and 20 facial morphologyical characteristics was measured and statistically analyzed. Results In terms of age groups, a total of 3 indicators which were opening height of eyeslits(
ABSTRACT
Burned bones have their unique characteristics in investigation of fire disaster/crimes, airplane disaster, explosion and other accidents. To study the morphological changes of skeletal tissue and DNA changes at different incinerating temperature might provide precise standard means to determine genera, sex, and age. Genetic locus was also applied in the above fields. The techniques to extract and detect of DNA in burning bones have been improved in recent years. In this article investigation advancement of analysis of burned bones with the morphology, histology, and molecular biology as well as the latest methods and techniques were reviewed. These results provide a new approach for further research and practice in forensic medicine.
