Analysis on Nutritional Status of Vitamin D Among Adults of 6 Ethnic Minority Groups Native to Yunnan Province / 昆明医科大学学报

Objective To assess the nutritional status of vitamin D and associated factors among adults of six ethnic minority groups native to Yunnan Province,and provide evidence for policy making.Methods Between May 2019 and August 2020,a total of 690 adults were selected from Jinuo,Bulang,Jingpo,Deang,Achang and Pumi ethnic groups according to the sex and age composition in the 6th national census.A questionnaire survey and an anthropometric examination were conducted by trained health workers,and serum 25(OH)D levels were determined with high-performance liquid chromatography-tandem mass spectrometry.Results The median of serum 25(OH)D was 28.7(P25～P75∶24.3～33.8)ng/mL,and the prevalence of vitamin D sufficiency,insufficiency and deficiency were 44.2%、47.5%and 8.3%,respectively.There were significant differences in serum 25(OH)D levels among the six ethnic groups(χ2=139.29,P<0.01).Multivariate logistic regression showed that ethnic groups living in higher latitude areas(Pumi,Jingpo,Deang,and Achang),women,and those whose BMI≥24.0 were more likely to be vitamin D insufficient or deficient.Conclusion More than half of the ethnic adults suffer from vitamin D malnutrition which also varies across ethnicities.Further surveillance and interventions among key areas and populations are needed.

Evaluation of the dietary quality of De'ang nationality residents over 18 years old in Yunnan by Diet Balance Index DBI_16 / 公共卫生与预防医学

Objective To evaluate the dietary quality of De'ang nationality residents over 18 years old in Yunnan Provinceusing the new adjusted Diet Balance Index (DBI_16), and to provide scientific basis for improving the nutritional status of De'ang residents and formulating health promotion strategies. Methods A food-frequency questionnaire was used to investigate the diet of De'ang residents, and the new adjusted dietary balance index (DBI_16) was used to evaluate the dietary quality. Results The dietary quality of De'ang nationality residents over 18 years old in Yunnan Province was in a moderately imbalanced state (DQD=42), and the main problem was insufficient dietary intake (LBS = 26). The dietary imbalance among men, 65-79 years old and low-income people was serious. The intake of milk, vegetables, fruits and aquatic products was the most insufficient and people who met the recommended intake levels of these foods were 2%, 34.7%, 31.8%, and 36%, respectively. Meanwhile, there existed the problem of excessive intakes among people studied in the present investigation. Pople who consumed more than recommended amount of Cereal food, livestock and poultry meat, and edible oil accounted for 76.9%, 60.4% and 63.5%, respectively. Conclusion The dietary structure of De'ang residents over 18 years old in Yunnan Province is unreasonable. The problems of both insufficient and excessive dietary intakes exist. Education on balance diet should be conducted to improve nutrition and health status of De'ang nationality residents.

Expression level of Dickkopf-1 protein in bone mesenchymal stem cells in Type 2 diabetic rats and its relationship with osteogenic activity / 中南大学学报(医学版)

To examine the growth activity and osteogenic differentiation of bone mesenchymal stem cells (BMSCs) in rats with Type 2 diabetes mellitus (T2DM) as well as the expression level of Dickkopf-1 (DKK-1) in bone marrow, and to explore the relationship between the osteogenic activity of BMSCs and the expression of DKK-1.
 Methods: The BMSCs were isolated from T2DM rats and were cultured in vitro. The BMSCs were divided into a T2DM group and a control group. The proliferation of BMSCs was detected by cell counting kit-8 (CCK8). Apoptosis rate was detected by annexin V- fluorescein isothiocyanate (FITC)/propidium iodide (PI) double staining. In the osteogenic induction phase, the expression level of alkaline phosphatase (ALP) in BMSCs was detected by ALP staining and ALP activity assay kit. The osteogenic differentiation of BMSCs was analyzed by alizarin red staining and mineralized nodule quantification. In addition, the expression of Runx2 and DKK-1 in BMSCs was detected by qRT-PCR.
 Results: Compared with the control group, the proliferation of BMSCs was decreased and the apoptosis was increased in the T2DM group (both P<0.01). In the osteogenic induction process of BMSCs, the expression of ALP significantly decreased, the formation of calcium nodules reduced, and the expression of osteoblast transcription factor Runx2 was down-regulated in the T2DM group compared with those in the control group (all P<0.01). The levels of DKK-1 protein and mRNA were up-regulated in the T2DM group, which were higher than those in the control group (both P<0.01). The levels of DKK-1 protein and mRNA were related to the increase of Runx2 (both P<0.01).
 Conclusion: The growth activity of BMSCs and the potential of osteogenic differentiation are attenuated in the T2DM rats, which may be related to the increase of DKK-1 expression in BMSCs.

Objective To analyze the changes and gender differences of organ coefficients, intestinal length and body size of SJ5-SPF chickens at different weeks of age,and to provide experimental data for the sex selection of laboratory chickens. Methods The body weight,the weight of 15 main organs,and length of 5 main segments of intestine and the 6 main parameters of body size of SJ5-SPF chickens at the age of 4,20,25 and 40 weeks were measured,respectively,and the organ coefficients were calculated. In addition, the gender differences in body weights, organ coefficients, intestinal lengths and body sizes between the female and male SJ5-SPF chickens at the four different weeks of age were compared, respectively. Results There were significant differences in body weights between the male and female SJ5-SPF chickens at each of the four different weeks of age(P < 0.01). The organ coefficients varied between females and males to different extents at different weeks of age. As for the intestinal length,there were no significant differences in the length of jejunum and ileum as well as rectum between the male and female chickens, while the length of duodenum, left cecum and right cecum showed gender differences at some of the four different weeks of age. During the determination of body size, there were gender differences in body length,shank length,pelvic width,chest depth and chest width at two or three of the four different weeks of age. Conclusions The organ coefficients, intestinal length and body size of SJ5-SPF chickens are affected by both their age and gender.
