Objective To analyze the characteristics of adult body composition and obesity status of three ethnic groups:Ewenki,Daur and Mongolian Buryat.Methods The bioelectrical impedance analysis(BIA)was used to measure 18 body composition components in three adults ethnic groups:245(male 124,female 121)Ewenki,207(male 90,female 117)Daur,and 181(male 74,female 107)Mongolian Buryat.The data were processed using Excel 2016 and SPSS 24.0 statistical software.Results The result of correlation analysis showed that visceral fat level was significantly and positively correlated with age(P＜0.01).Stature,total body muscle mass,estimated bone mass and trunk muscle mass were all significantly and negatively correlated with age(P＜0.01)in males and females of the three ethnic groups.The percent body fat,percent left upper limb fat and percent trunk fat were positively correlated with age in Ewenki males(P＜0.05 or P＜0.01)and the percent body fat,body mass index(BMI),percent limb fat and percent trunk fat were positively correlated with age in Ewenki females(P＜0.05 or P＜0.01).Body weight,BMI,percent left upper limb fat,left upper limb muscle mass,bilateral lower limb fat and muscle mass were all negatively correlated with age in Daur males(P＜0.05 or P＜0.01).Body weight,upper limb muscle mass and left lower limb muscle mass were negatively correlated with age(P＜0.05 or P＜0.01)in Mongolian Buryat males and percent trunk fat was positively correlated with age(P＜0.05)in Mongolian Buryat females.Comparison between ethnic groups showed that most of the body composition index values of the Ewenki and Mongolian Buryat divisions were closest to each other,and the body fat content was higher than that of the Daur.BMI,percent body fat and visceral fat level were all manifested in the Mongolian Buryat Department＞Ewenki＞Daur.Cluster analysis showed that Ewenki,Daur and Mongolian Buryat were closer to the northern groups and further from the southern groups.Conclusion The Ewenki is most similar to the Mongolian Buryat in body composition characteristics all three ethnic groups has a more serious obesity problem.

The combination of disease-specific human induced pluripotent stem cells (iPSC) and directed cell differentiation offers an ideal platform for modeling and studying many inherited human diseases. Wilson's disease (WD) is a monogenic disorder of toxic copper accumulation caused by pathologic mutations of the ATP7B gene. WD affects multiple organs with primary manifestations in the liver and central nervous system (CNS). In order to better investigate the cellular pathogenesis of WD and to develop novel therapies against various WD syndromes, we sought to establish a comprehensive platform to differentiate WD patient iPSC into both hepatic and neural lineages. Here we report the generation of patient iPSC bearing a Caucasian population hotspot mutation of ATP7B. Combining with directed cell differentiation strategies, we successfully differentiated WD iPSC into hepatocyte-like cells, neural stem cells and neurons. Gene expression analysis and cDNA sequencing confirmed the expression of the mutant ATP7B gene in all differentiated cells. Hence we established a platform for studying both hepatic and neural abnormalities of WD, which may provide a new tool for tissue-specific disease modeling and drug screening in the future.

Objective To investigate the body characteristics of zhuang-dong ethnic group. Methods Totally 14 Zhuang-Dong languages in Guizhou, Guangxi, Yunnan, Hainan and Hunan were measured with anthropometry. Results The foot breadth, upper arm length and forearm length of male of Zhuang-Dong ethnic group were not correlated with age, while crista iliaca breadth was positively correlated with age (P<0. 01), 24 indexes including weight, stature and tragion height are negatively correlated with age (P<0. 05 or P<0. 01) . Six indicators of Zhuang-Dong female' s foot breadth, hand length, height of suprasternal notch above sitting plane, upper extremity length, lower extremity length and upper arm length were not related with age, while four indicators of hand breadth at metacarpale, crista iliaca breadth, total arm length and forearm length were positively correlated with age (P< 0. 05 or P< 0. 01), while 18 indicators of weight, stature and tragion height were negatively correlated with age (P<0. 05 or P <0. 01). The vast majority of body index values had statistical significance among age groups. The average value of all body indexes of Zhuang-Dong ethnic groups was larger than that in female (P<0. 05 or P<0. 01), that was, the height, length and width of male body were larger than that of female. Principal component analysis showed that, the stature, sitting height, height of suprasternal notch above sitting plane and weight of Lingao people, Li nationality men and women were larger than those of other 12 Zhuang-Dong language group. Mulao and Bajia had similar human body characteristics. In addition, the mean values of human body indexes of the 14 Zhuang-Dong language group, Bulang ethnic group and Gejia ethnic group were lower than those of the northern Han nationality, the Mongolian Balhu ethnic group, the Mongolian Erdos ethnic group, the Heshuo ethnic group in Qinghai, the Uzbek ethnic group, the southern Han nationality, the Mosuo ethnic group, the Qiang ethnic group and the Yi ethnic group. Conclusion Men and women in Zhuang-Dong ethnic group have little weight, while men' s height belongs to short stature and female's height belongs to sub-medium stature. Zhuang-Dong ethnic group has the physical characteristics of ethnic minorities in southern China, and belongs to the physical type of short stature and light weight.

To summarize and analyze the current adjuvant sleep-improving Chinese medicinal health products,this study retrieved the information on health products with the sleep-improving effect published by the Department of Special Food Safety Supervision and Management,State Administration for Market Regulation( SMAR),which was statistically analyzed with Microsoft Excel and TCMISS for the characteristics of formulations. A total of 435 sleep-improving health products were collected,including 344 ones containing Chinese herbal medicines. Among them,413 health products were not suitable for adolescents,neither 194 for pregnant women. Ten Chinese herbal medicines showed a frequency of use ≥40,with 1 095 times( 73. 1%) in use. Through unsupervised hierarchical entropy-based clustering of the above Chinese herbal medicines of health products( degree of support of 45 and confidence coefficient of0. 7),12 new formulas were obtained. The composition of Chinese herbal medicines was consistent with the principles of improving sleep in traditional Chinese medicine( TCM) theories,i. e.,replenishing the heart and spleen,nourishing blood,calming the nerves,nourishing Yin,reducing internal heat,communicating the heart and kidney,replenishing Qi,relieving convulsions,clearing heat,resolving phlegm,regulating the middle warmer,soothing the liver,relieving heat,and calming the heart. According to TCM theories,syndrome differentiation was performed based on the existing sleep-improving health products,followed by data mining and analysis according to the formulation regularity,aiming to provide new ideas for the development of new Chinese medicinal health products. In particular,attention should be attached to the requirements of special populations to provide a basis for follow-up studies,exert the advantages of TCM,and lay a foundation for Chinese medicinal health products to service the public.

In this study, UPLC-Q-Exactive-MS/MS was used to rapidly analyze the chemical constituents of Meconopsis quintupli-nervia, and the anti-liver fibrosis mechanism of M. quintuplinervia was preliminarily analyzed by network pharmacology, molecular docking, and cell experiments. The chemical constituents of M. quintuplinervia were identified according to the information of MS~1 and MS~2, as well as the data in the literature and databases. SwissTargetPrediction and TargetNet were used to predict the potential targets. The targets related to liver fibrosis were collected from GeneCards and OMIM. The protein-protein interaction(PPI) network was constructed by STRING. Cytoscape 3.6.1 was used to construct and analyze the "constituent-target-disease" network to obtain key targets and their corresponding constituents in the network. DAVID 6.8 was used for GO analysis and KEGG signaling pathway enrichment analysis. Finally, the preliminary verification was carried out by molecular docking and cell experiments. As a result, 106 chemical constituents were identified from M. quintuplinervia, including 66 flavonoids, 16 alkaloids, 18 phenolic acids, 1 anthocyanin, and 5 other constituents. Among them, 3 constituents were identified as potential new compounds, and 59 constituents were reported in M. quintuplinervia for the first time. Network pharmacology analysis showed that M. quintuplinervia presumably acted on AKT1, SRC, JUN, EGFR, STAT3, HSP90 AA1, MAPK3, and other core targets through luteolin, isorhamnetin, quercetin, apigenin, kaempferide, amurine, 2-methylflavinantine, allocryptopine, the multi and other active compounds, thereby regulating the PI3 K/AKT signaling pathway, pathways in cancer, proteoglycans in cancer, FoxO signaling pathway, and other pathways to exert anti-liver fibrosis effects. M. quintuplinervia extract(MQE) could significantly down-regulate PI3 K and AKT protein levels in the HSC-T6 cell model induced by TGF-β1, suggesting that MQE may have the ability to regulate the PI3 K/AKT signaling pathway. The findings of this study indicated that the anti-liver fibrosis effect of M. quintuplinervia had multi-constituent, multi-target, and multi-pathway characteristics, which may provide a scientific basis for the research on the pharmacodynamic materials, action mechanism, and quality markers of M. quintupli-nervia.
