Body characteristics of adults from 17 minorities of the Tibeto-Burman language group in China / 解剖学报

Objective To understand the body characteristics of adults from the Tibeto-Burman language group. Methods Totally 14 837 adults (6578 males and 8259 females) from 17 minorities were selected for investigation during 2015 to 2019 and these surveys were carried out in regions including Sichuan, Yunnan, Guizhou, Hubei, Hunan and Tibet Autonomous Region. Eight physical parameters (stature, sitting height, etc.) along with 4 corresponding indexes (stature-sitting index and the like) were carefully analyzed. The body characteristics of the Tibeto-Burman language group were then compared to those of certain minorities as well as Han in both northern and southern part of China based on our collected data. Results Among 17 minorities of the Tibeto-Burman language group, people from Pumi and Tibet were relatively tall and have longer trunk and limbs. The presence of wider trunk and thicker limbs appeared to be common in Tibetan individuals. Subjects from Lahu, Jino and Derung were in possession of shorter stature and limbs while the trunk of Naxi, Lisu and Achang people seemed wider. Compared with other ethnic groups in China, individuals from the Tibeto-Burman language group tended to own shorter stature accompanied by medium trunk width, probably sharing similar physical characteristics with those minorities in southern China, especially She and Li. Conclusion Among ethnic groups dotting in southern China, individuals from the Tibeto-Burman language group generally have medium stature, medium trunk height, and wide trunk whereas those from 3 Mon-Khmer groups, Va, Khmus and Blang, are shorter and smaller in width and height of the trunk.

Objective To investigate the characteristics of bod)' circumference of Tibetan-Burman adults. Methods Using a human bod)' altimeter and a measuring tape, the height and 9 circumference indicators of 14 722 adults from 17 Tibetan-Bunnan ethnic groups in Sichuan, Yunnan, Guizhou, Hubei, Hu ' nan and Tibet Autonomous Region were measured from 2015 to 2019, 5 circumference indexes were calculated, and the data were statistically analyzed. Results The higher the longitude, the larger the head circumference, thigh circumference, biceps circumference and foreann circumference of Tibetan-Bunnan adults and the female maximum biceps circumference, and the smaller the trunk circumferences and male calf circumference; The higher the latitude, the larger the circumferences (except for female thigh circumference); The higher the altitude, the larger the circumferences; The higher the temperature, the smaller the circumferences. Conclusion Among the 17 ethnic groups of Tibeto-Burman, the Tibetan has a larger circumference, while the Gongshan Nu, Lahu, and Drung have relatively small and close circumferences. With age, the chest and waist circumferences of Tibetan-Bunnan adults increase, and the circumference of the limbs decreases.

Facial changes of Mongolian nationality from youth to old age in China / 解剖学报

Objective To explore the law of changes in the appearance of Chinese Mongolians with age. Methods Totally 24 human indexes of head and face from 4410 cases (1916 males and 2494 females) and 13 Mongolian ethnic groups were measured, and 12 craniofacial indexes were calculated. Correlation analysis was used to study the changes of craniofacial indexes and indexes with age. The method of analysis of variance was used to study whether the differences between the index values and index values of the three age groups were statistically significant. Results With the increase of age, the distance between the two mandibular angles became wider, the mouth widened, the width, height and length of the nose increased, the skin of the upper lip increased, the length and width of the ear increased, the width of the head, forehead, face, mastoid and tragus narrowed, the width of the eyes narrowed, the upper and lower lips thinned, the circumference of the head and the height of the head decreased, and the length of the head did not change significantly. With the increase of age, the Mongolian face becomes narrower and longer, the proportion of the height of the face in the whole head high school increases, the nose becomes wider, and the head appears to be relatively longer, lower and wider. The distance between the left and right frontotemporal points is relatively closer, the mouth cleft appears more slender, and the ratio of length to width of the ear does not change much. Conclusion With the increase of age, the facial features of Mongolian have changed.

Fat distribution in Zhuang-Dong ethnic groups and its relationship with age in China / 解剖学报

Objective To reveal the relationship between lipid distribution and age in Zhuang-Dong ethnic group in China. Methods By bioelectrical impedance analysis method of Zhuang-Dong 13 ethnic body composition in China, u inspection method, for the inspection of body composition differences between the sexes, the indicators by adopting the method of correlation analysis on body composition and age related analysis, variance analysis method was used to explore three body composition differences between age groups. Results The body fat rate was not high and did not reach the obesity level. Half of the men and more than half of the women had fat rates in the standard range. The body fat rate of Dong nationality and Bouyei nationality was higher, but that of Kelao nationality and Kelao nationality was lower. With age, there was no significant change in the upper limb fat rate of males, while the visceral fat rate and trunk fat rate increased, and the lower limb fat rate decreased. There was little change in the total fat rate and the lower limb fat rate. With age, there was no significant change in body mass index (BMI), total fat percentage, trunk fat percentage, and limb fat percentage. Women had a significantly higher percentage of body fat than men. There was no significant correlation between left and right upper limb fat rate and age in males, body fat rate, visceral fat level and trunk fat rate were significantly positively correlated with age, and left and right lower limb fat rate and age were significantly negatively correlated. The left upper limb fat rate, left and right lower limb fat rate were negatively correlated with age, and the trunk fat rate was positively correlated with age. There was no significant correlation between age and total female lipid. Conclusion The body fat of Zhuang-Dong ethnic group in China is much thinner than that of north Asian ethnic group, and it has the characteristic of sebum development level of southern Chinese ethnic group.

Feasibility of neck circumference in evaluating adult obesity / 解剖学报

Objective To study the feasibility of neck circumference on the prediction of obesity by analyzing the relationship between the neck circumference and the obesity, and to provide the reference for the early prevention of obesity and related diseases. Methods A total of 1859 adults (911 males and 948 females) were selected from the four ethnic groups of Lingao, Li, Qiang and Baima as the subject of the study. The correlation between the neck circumference and body mass index (BMI), percent body fat, visceral fat index, waist circumference, waist hip ratio and body adiposity index were analyzed by correlation analysis, u test and receiver operating characteristic (ROC) curve analysis and Kappa consistency test. Results Neck circumference has significant positive correlations with several other obesity indicators. It has the least correlation with body adiposity index and waist hip ratio, and has greater correlation with waist circumference, visceral fat index, and percent body fat, and has the largest correlation with BMI. The average values of the neck circumference of the obesity group judged by different obesity indicators are larger than the normal group, and the difference is statistically significant. ROC curve analysis and Kappa consistency test show that the area under curve (AUC) of neck circumference and various obesity indicators are greater than 0.7, and the consistency of neck circumference, BMI and waist circumference is the best when judging obesity. Conclusion If the value of male neck circumference is greater than the critical cut point value 364.5, the female neck circumference value is greater than 319.5, which can be predicted that the BMI value is overweight or obese. When the neck circumference of male is greater than 370.5 and the neck circumference of female is greater than 319.5, it can be predicted that the waist circumference exceeds the standard, and the risk of central obesity increases.

Expressions of melanoma lineage antigens and nuclear antigen Ki-67 and their correlations with prognosis in melanoma patients / 中国肿瘤生物治疗杂志

@#[Abstract] Objective: To explore the expression patterns of melanoma lineage antigens and nuclear antigen Ki-67 and their correlations with survival in melanoma patients. Methods: A retrospective analysis was conducted to analyze the pathological data of melanoma patients treated at the Department of Melanoma, Peking University Cancer Hospital from February 2008 to August 2020, mainly including the expression patterns of melanoma lineage antigens (S-100, HMB-45, Melan-A) and Ki-67, demographics, clinical features and survival. The correlation between expression patterns of melanoma lineage antigens, Ki-67 and melanoma-specific survival (MSS) was analyzed. Results: In total, 603 patients were included in this study. The median follow-up time was 47.4 months. The positive rates of S-100, HMB, and Melan-A were 92.8%, 92.1% and 90.0%, respectively. The percentages of patients with melanoma lineage antigen scores (S-100, HMB-45 and Melan-A was scored each, as 1 when positive and 0 when negative) of 0, 1, 2, and 3 were 0.5%, 5.0%, 15.6%, and 78.8%, respectively. The percentages of patients with Ki-67 scores of 0, 1, 2, and 3 were 43.0%, 36.3%, 16.3%, and 4.5%, respectively. Ki-67 was highly expressed in mucosal and progressive melanomas. In a multivariate analysis, Ki-67 expression was an independent prognostic factor for poorer MSS (HR=1.506, 95%CI: 1.248-1.818, P<0.001) as the incidence of MSS event increased by 50% per 25% increase in Ki-67 expression, whereas there was no statistical correlation between melanoma lineage antigen expression and MSS (HR=0.991, 95%CI: 0.759-1.293, P=0.94). Conclusion: High expressions melanoma lineage antigens are ubiquitous in melanoma tissues, and Ki-67 is an independent prognostic factor for MSS.

Soluble PD-L1 as a prognostic factor for advanced acral and mucosal melanoma / 中国肿瘤生物治疗杂志

@#[Abstract] Objective: Elevated levels of soluble PD-L1 (sPD-L1) are associated with worse prognosis of renal cell carcinoma and multiple myeloma. However, the regulatory roles and functions of sPD-L1 in advanced melanoma are not fully understood. This study was designed to evaluate the association between circulating sPD-L1 concentrations and prognosis of patients with advanced acral or mucosal melanoma. Methods: A total of 102 untreated patients with advanced acral and mucosal melanoma admitted to Peking University Cancer Hospital between January 2012 and December 2015 were enrolled in this study. In the meanwhile, peripheral blood samples were obtained from 40 healthy donors. Circulating sPD-L1 concentrations were determined using an enzyme-linked immunosorbent assay. Results: The advanced melanoma cohort included 58 acral melanoma patients and 44 mucosal melanoma patients. The pre-treatment concentration of sPD-L1 (2.91±2.23 ng/ml) in plasma of patients group was elevated as compared with that in healthy donors (0.59 ng/ml). The concentration of sPD-L1 in serum was significantly upregulated in 39/102 (38.2%) patients and significantly associated with increased LDH level (P=0.021) and number of Tregs (P=0.017). The overall survival rates of patients with high or low concentrations of sPD-L1 were statistically different (8.5 months [high level] vs 11.6 months [low level], P=0.022). Conclusion: sPD-L1 concentration is elevated in patients with advanced acral or mucosal melanoma, which may play an important role in predicting prognosis.

PCR-based sensitive detection of the edible fungus Boletus edulis from rDNA ITS sequences

Identification of commercially important fungi, such as the valuable edible fungus Boletus edulis can be difficult considering visual or metabolic approaches. Based on phylogenetic analysis of the rDNA ITS sequence, a pair of specific primers was designed for differentiating B. edulis from other mushrooms by PCR. PCR was performed with total DNA as a template at an annealing temperature between 56-60ºC. Positive amplicons were obtained from B. edulis with all DNA templates from fruit bodies and cultured mycelium, but not from other fungal species at an annealing temperature of 60ºC. The result indicated that B. edulis could be clearly distinguished from other fungi by PCR, and there were no misidentifications under the reaction conditions used. The primers were also successfully employed to identify various tissues of B. edulis.
