ABSTRACT
Objective@#To analyze the influencing factors and physical and mental development of preschool children with iron deficiency anemia in Dongguan, so as to provide a reference for the prevention of iron deficiency anemia among preschool children.@*Methods@#A total of 118 preschool children with iron deficiency anemia who were examined in Dongguan Maternal and Child Health Center from January 2022 to December 2022 were enrolled in the anemia group, and 118 preschool healthy children who were examined in the hospital at the same time were enrolled in the control group. The physical and mental development of the children were evalucded in both groups. Demographic information and household per capita income were collected. The relationship between risk factors and iron deficiency anemia was analyzed by univariate analysis and multiple Logistic regression.@*Results@#The scores of fine motor skills, gross motor skills, adaptability, social communication, language ability and developmental quotient of children in anemia group were significantly lower than those in control group ( t =4.14, 5.46, 5.60, 5.50, 4.90, 5.83, P <0.01). The difference in scores of adaptability, fine motor skills, gross motor skills language ability, social communication and developmental quotient between the two groups increased with age ( F =390.56, 414.63, 437.35, 409.68, 407.20, 404.54, P < 0.05 ). Multivariate Logistic regression analysis showed that household income, history of past digestive disease, gestational age, maternal anemia during pregnancy, maternal education, consumption of meat, eggs and milk, and intake of nuts were all associated with iron deficiency anemia among preschool children in Dongguan ( OR =2.23，2.99，3.99，3.56，3.11，1.68，1.61, P < 0.05 ).@*Conclusion@#The physical and mental development of preschool children with iron deficiency anemia in Dongguan is slower than that of non anemia children of the same age, and the development delay becomes more obvious with increasing age. Attention should be paid to the prevention of iron deficiency anemia among preschool children. It is important to provide reasonable dietary guidance for children with high risk factors such as digestive disease history and prematurity.
ABSTRACT
p300/CBP-associated factor (PCAF)is an important histone acetyltransferase in eukaryotic cells. PCAF can acetylizes histone and non-histone. PCAF participates in various biological processes of cells and in the interaction between virus and cells. The imbalance of PCAF would lead to abnormal development of various organs, and related to the development of some tumors.
ABSTRACT
Tumors of the sacrum are rare.The valve of adjuvant is uncertain,and en bloc tumor resection remains the primary mode of treatment.But en bloc tumor resectiong often leads to unstability of the pelvic ring.Therefore,the most factor providing the successful outcome in the management of sacral tumor is how to establish stability in the lumbo-sacrai junction.The various spinopelvic reconstruction techniques are reported in the literature.This includes various methods triangular frame reconstruction,or lilac rod or iliac screw fixation,modified galveston,custom-made prosthesis and so on.The authors review the modes of reconstruction after sacral tumor resection and discuss the outcomes.
ABSTRACT
Differential proteome profiles of human lung squamous carcinoma tissue compared to paired tumor-adjacent normal bronchial epithelial tissue were established and analyzed by means of immobilized pH gradient-based two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). The results showed that well-resolved, reproducible 2-DE patterns of human lung squamous carcinoma and adjacent normal bronchial epithelial tissues were obtained under the condition of 0.75-mg protein-load. The average deviation of spot position was 0.733+/-0.101 mm in IEF direction, and 0.925+/-0.207 mm in SDS-PAGE direction. For tumor tissue, a total of 1241+/-88 spots were detected, 987+/-65 spots were matched with an average matching rate of 79.5%. For control, a total of 1190+/-72 spots were detected, and 875+/-48 spots were matched with an average matching rate of 73.5%. A total of 864+/-34 spots were matched between tumors and controls. Forty-three differential proteins were characterized: some proteins were related to oncogenes, and others involved in the regulation of cell cycle and signal transduction. It is suggested that the differential proteomic approach is valuable for mass identification of differentially expressed proteins involved in lung carcinogenesis. These data will be used to establish human lung cancer proteome database to further study human lung squamous carcinoma.
