Objective: To learn the status and influencing factors of 0-3-year-old children's development screening in Tongzhou District, Beijing Municipality, so as to provide the reference for early intervention measures. Methods: Data of children who were born from September 1, 2020 to August 31, 2022 and had received Denver Developmental Screening Test (DDST) in Tongzhou District Community Health Service Center before September 1, 2023 were collected through the Beijing Maternal and Child Healthcare Information System, including basic birth information, mother's situation and DDST results. The screening positive rates of DDST among children were analyzed, and factors affecting positive DDST were identified using a multivariable logistic regression model. Results: A total of 27 783 children aged 0-3 years were included, with a median age of 0.91 (interquartile range, 0.71) years. There were 14 320 boys (51.54%) and 13 463 girls (48.46%). There were 2 471 preterm births (8.89%) and 2 248 mothers with health problems during pregnancy (8.09%). The positive rate of DDST was 2.25%. Multivariable logistic regression analysis showed that gender (boy, OR=1.228, 95%CI: 1.045-1.444), preterm birth (OR=2.417, 95%CI: 1.890-3.092), low birth weight (OR=2.583, 95%CI: 1.980-3.371) and maternal health problems during pregnancy (OR=2.012, 95%CI: 1.591-2.545) were factors affecting positive DDST among children at ages of 0 to 3 years. Conclusions The positive rate of DDST among children at ages of 0 to 3 years was 2.25% in Tongzhou District. Gender, preterm birth, low birth weight and maternal health problems during pregnancy may affect positive screening for developmental delay.

Objective To obtain the change of bcl-2/bax/fas/fasL in splenic lymphoctyes with different lasting time of hypoxicischemic brain damage (HIBD). Methods The newborn rat were divided into 6 groups by the time of being HIBD model randomly, includes 1/6/12/24/48/72 hour(s) (8 for every group),and control groups were established at the same time point. The following four apoptosis related genes bcl-2/bax/fas/fasL were tested by real time PCR. Results ( 1 ) bcl-2: the mRNA expressions of HIBD groups were lower than control groups at the same time ( P<0.01 ). Eliminated the control effects, the mRNA expressions of HIBD groups were differernt by the modeling time(P ＜0.01 ). (2)bax: the mRNA expressions of HIBD groups were higher than control groups at the same time( P ＜0.01 ), and in control group the expression of 6 h was much higher than any other groups (P<0.01 ). Eliminated the control effects, the mRNA expressions of H IBD groups were different by the modeling time( P<0.01 ). (3)bcl-2/bax: the ratios of HIBD groups were lower than control groups at the same time( P ＜0.05 ), the ratios in control groups were higher than 1 ( except for 1 h); while in HIBI) groups the ratios were lower than 1; Eliminated the control effects, the ratios were different in all the groups. (4)fas: the mRNA expressions of HIBD groups were higher than control groups at the same time ( P ＜0.01 ), and both were maximum at 6 h. (5)fasL: the mRNA expressions of HIBD groups were higher than control groups in 1 h and 6 h ( P<0.01 ), while lower than control group at other time points( P<0.01 ),the expression of 24 h was the maximum of control groups and 12 h was the maximum of HIBD groups. (6)fas/fasL: the ratios of HIBD groups were higher than control groups( P ＜0.01 ) (except for 6 h), and the ratios in control groups were lower than 1 ( P<0.01 ) ( except for 6 h), and not concentrated, while in HIBD groups were higher than 1 ( except for 24 h), between 0.69 to 5.65. Conclusion Pro-apoptosis genes ( include bax/fas/fasL) were promoted by HIBD, while anti-apoptosis gene(bcl-2) was inhibited. The maximum of pro-apoptosis genes became early in HIBD. Both the pro- and anti-apoptosis genes got their maximum at 6 h and 12 h of HIBD. The apoptosis suppression was the main effects in control groups from the ratio of bcl-2/bax, which was lower than 1. The apoptosis promotion was the main effects in HIBD groups from the ratio of bcl-2/bax, which was higher than 1, especially at 12 h. Thefas/fasL effect which is the major way of lymphocytes apoptosis was strengthened in HIBD.

Objective To report a consanguineous family with lamellar ichthyosis and to detect the mutations in transglutaminase 1 (TGM1) gene in this family. Methods Genomic DNA was extracted from the blood samples of a 19-year-old male patient with lamellar ichthyosis, his family members and 100 normal human controls. PCR was carried out to amplify all the encoding sequences (15 exons) and adjacent flanking sequences of TGM1 gene followed by bidirectional sequencing. Results A C1666T mutation in the 11th exon in TGM1 gene, which resulted in the substitution of ACA (threonine) by ATA (isoleucine) at codon 529, was detected in the proband, while both his parents carried the C1666T mutation in heterozygous form, and his sister was a C/C homozygote. None of the 100 normal control individuals carried the mutation in TGMlgene. Conclusions The de novo mutation from ACA (threonine) to ATA (isoleucine) at codon 529, may contribute to the development of lamellar ichthyosis. Consanguineous marriage can increase the risk for lamellar ichthyosis by raising the probability of homozygosis of C 1666T mutation in TGM 1 gene.
