ABSTRACT

Objective@#To describe the status quo of overweight and obesity among children aged 3 to 5 in Beijing and Tokyo, and to explore its relationship with lifestyle.@*Methods@#Using the method of cluster stratified random sampling, a sample of 444 children aged 3-5 years from Beijing and Tokyo were selected in Oct. and Nov. of 2019. Height, weight and lifestyle were measured. Overweight and obesity among children in the two cities and its relationship with lifestyle were compared and analyzed.@*Results@#Average level of BMI, rate of overweight and obesity of children in Beijing(25.28%) were higher than those in Tokyo( 18.44 %). There were significant differences in overweight and obesity rates between children in Beijing and Tokyo with physical activity before breakfast( χ 2=29.14, 31.18, P <0.05). There were significant differences in overweight and obesity rates between children in Beijing and Tokyo with different snack frequency after dinner( χ 2=24.72, 21.93, P <0.05). Logistic regression analysis further showed that children s lack of physical activity before breakfast in Beijing is positively related to overweight and obesity( OR= 1.45, 95%CI =1.10-2.68). Beijing children who often eat snacks after supper ( OR=2.56, 95%CI =1.44-3.57,) and sometimes eat snacks were positively correlated with the occurrence of overweight or obesity ( OR=1.72, 95%CI =1.21-2.72).@*Conclusion@#The prevalence of overweight and obesity among preschool children in Beijing is higher than that in Tokyo. Potential risk factors for overweight and obesity among infants in Beijing include lack of physical activity before breakfast and frequent snacking after dinner.

ABSTRACT

OBJECTIVE: To investigate the expression of cystic fibrosis transmembrane conductance regulator (CFTR) protein in patients with acute leukemia and its relationship to clinical features and prognosis of acute leukemia. METHODS: A total of115 patients with acute leukemia were enrolled in the experimental group and 20 healthy individuals were used as control. Peripheral blood or bone marrow samples were collected, and mononuclear cells were isolated. The expression of CFTR protein was detected by Western blot. The relationships of CFTR protein expression to clinical features and prognosis was analyzed. RESULTS: The expression of CFTR protein was not detected in peripheral blood mononuclear cells of normal control, while it was positive in more than half of acute leukemias including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), but negative in the patients with acute promyelocytic leukemia (M3). In the patients with AML, there was no difference in peripheral white blood cells (WBC), peripheral blast cells, platelet and hemoglobin (HGB) between CFTR-positive and CFTR-negative patients. There was no relationship between the expression of CFTR protein and gene mutations such as NPM1, CEBPA, FLT3-ITD, and C-Kit. Complete remission (CR) rate after two course in CFTR-negative patients was slightly higher than that in positive patients. The survival time of CFTR-negative patients was little longer than that of positive patients, but the difference was not statistically significant. CONCLUSIONS: The expression of CFTR protein seems not associated with clinical features, treatment response and prognosis in the patients with acute leukemia.

ABSTRACT

OBJECTIVE: To evaluate the effect of water pollution with dexamethasone on intestinal flora in mice. METHODS: Twenty Balb/c mice were randomly divided into control group and low-, moderate- and high-dose dexamethasone groups. The mice in dexamethasone groups were exposed to dexamethasone sodium phosphate in drinking water at doses of 0.035, 0.225, and 2.25 ng for 36 days. The changes in behaviors, fur condition, and feces of the mice were observed daily. All the mice were sacrificed at 36 days and the tissues in the ileocecal region was collected for denaturant gradient gel electrophoresis (DGGE) of 16S rDNA V6 variable regions of microbes and sequence analysis with BLAST. RESULTS: The mice in the 3 dexamethasone groups all showed aggressive behaviors. Cluster analysis of DGGE graph showed relatively stable floras in the ileocecal region in all the mice, but principal component analysis identified differences in the dominating flora among the groups. Diversity analysis of the flora revealed significantly increased amount and types of bacteria in the intestinal flora in all the 3 dexamethasone groups (P<0.05 or 0.01) compared with the control group. Sequence analysis of 16S rDNA V6 regions showed 15 common bacterial species and 2 differential species between the dexamethasone groups and the control group with changes in the type and proportion of the dominating bacterium in the dexamethasone groups. Lactobacillus colonization was detected in the control group but not in moderate- and high-dose dexamethasone groups, and Shigella species were found in the latter two groups. CONCLUSIONS: Water contamination with dexamethasone can affect the nervous system of mice, cause changes in the types and amounts of intestinal bacteria and the dominating bacteria, and inhibit the colonization of probiotics in the intestinal floras to increase the risk of invasion by intestinal pathogenic bacteria.
