RESUMEN

Objective@#To understand the status quo and influencing factors of overweight and obesity in preschool children, and to provide scientific theoretical reference for the prevention and control of overweight and obesity in preschool children in Urumqi.@*Methods@#Stratified cluster sampling method was adopted to select 1 897 preschool children from 10 kindergartens in Urumqi from October to December in 2021 to understand the status quo of overweight and obesity of preschool children by measuring their height and weight. The influencing factors were collected by questionnaire survey, including Chinese preschoolers eating behavior questionnaire, Chinese preschooler s caregivers feeding behavior scale, 3-6 year old children s home nurture environment scale, and characteristics and influencing factors of physical activity among preschool children.@*Results@#The prevalence of overweight and obesity in preschool children was 31.21% (592), including 19.50% (370) overweight and 11.70% (222) obesity.Childhood overweight and obesity detection rates varied significantly by age, sex, child dietary habits, father BMI, maternal BMI, and maternal pre pregnancy BMI ( χ 2=19.63,28.75,9.45,18.21,18.45,19.36, P <0.05). Multivariate Logistic regression analysis showed that gender, children s eating habits, paternal BMI, pregnancy BMI, satiety responsiveness, external eating, initiative eating, weight concerns, behavior restricted feeding, physical activity and family physical activity environment were the influencing factors of overweight and obesity in preschool children( OR =0.52,1.43,1.51,1.44,0.69,0.74,1.35,1.71,0.81,0.96,1.10, P < 0.05 ).@*Conclusion@#Overweight and obesity in preschool children are popular in Urumqi. Education, diet control and scientific exercise should be strengthened to prevent childhood overweight and obesity.

RESUMEN

Objective To investigate the role and clinical significance of RANTES in endometriosis (EM). Methods The serum level of RANTES was examined by ELISA in 50 patients with endometriosis (EM group), 32 patients with benign ovarian neoplasms (disease control group) and 30 normal control women (normal control group). The level of RANTES in peritoneal fluid was examined in EM group and disease control group. Results The serum level of RANTES was significantly higher in EM group (108.73±60.69) ng/L than that of disease control group (31.26±20.33) ng/L and normal control group (29.77 ± 11.58) ng/L (P<0.05). The level of RANTES in peritoneal fluid was significantly higher in EM group (726.31 ± 259.83) ng/L than that of disease control group (116.19 ± 81.64) ng/L (P<0.05). The levels of RANTES in serum and peritoneal fluid in EM group were positively correlated with clinical stage respectively (rs=0.501 and 0.562,P<0.01). The level of RANTES in peritoneal fluid in EM group was positively correlated with dysmenorrhea score (rs=0.527,P<0.01). The serum level of RANTES was positively correlated with the level of RANTES in peritoneal fluid in EM group (rs=0.363, P<0.05). The levels of RANTES in serum and peritoneal fluid were positively correlated with inflammatory response degree in endometriotic tissues in EM group (rs=0.326 and 0.391,P<0.05 or P<0.01).Conclusion Detection of the serum level of RANTES by ELISA may be one of parameters for diagnosis of endometriosis.

RESUMEN

BACKGROUND: Myogenetic seed cells are the fundamental for construction of tissue-engineered smooth muscle, and optimizing the amplification of seed cells is the key in further clinical application. OBJECTIVE: To analyze the myogenetic potential of rabbit adipose-derived stromal cells induced with the combination of MyoD, transforming growth factor β1 and 5-azacytidine, and to investigate a new way to induce cells. METHODS: The rabbit abdominal fats were isolated and then the adipose-derived stromal cells were separated by col agenase digestion method for myogenetic induction with different methods: 5-azacytidine induction group, MyoD+transforming growth factor β1 induction group, 5-azacytidine+MyoD+transforming growth factor β1 combination induction group. The blank control group was set. The morphological characteristics of cells were observed at 1, 4, 8, 12, 16, 20, 24 and 28 days after induction, and the col agen type Ⅲ level were detected with 4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry and immunohistochemistry. RESULTS AND CONCLUSION: Compared with the other groups, the cel activity was higher in the combination induction group and reached peak at 16 days after induction, the number and volume of myotubes were increased at 20 days with regular arrangement, and desmin showed strong expression. Cel cycle showed the ratio of adipose-derived stromal cells in the DNA replication phase was increased in the combination induction group, the ratio of cells in the clearance period was decreased; the level of col agen type Ⅲ was increased significantly, and the difference was significant. The results indicate that 5-azacytidine combined with multiple factors can promote the differentiation of adipose-derived stromal cells into myoblasts with significant cel proliferation, which is considered as the ideal method to in vitro induction of myoblasts.
