METHODS: Totally 816 full-term infants admitted in the neonate intensive unit of Boai Hospital of Zhongshan between 1 May, 2008 and 30 June, 2011 were included in the study. Fundus examination was performed and evaluated individually on them at the age of 48 hours after delivery, 2 weeks and 1 month. Some possible risk factors happening prenatally or during delivery such as pregnant related hypertension, placenta previa, placental abruption etc, as well as some neonatal risk factors such as neonatal asphyxia, hypoxic-ischemic encephalopathy (HIE), low birth weight etc, were recorded and evacuated. Then the effect of the risk factors of full-term infants on retinopathy was studied. RESULTS: The incidence of retinal hemorrhage of full-term infants with prenatal pregnant related hypertension (PRH) of the mother (43.6%) was significantly higher than that of full-term infants without (8.0%). (P<0.001). The incidence of retinal hemorrhage of full-term infants with neonatal asphyxia and /or hypoxic-ischemic encephalopathy (HIE)(29.3%) was significantly higher than that of those without (15.7%), but correlation was not found between the severity of retina hemorrhage and the degree of hypoxic disease. A pale color of optic disc was associated with a low birth weight of full-term infant. Full-term infants with birth weigh-less than 2500g had a significant higher incidence of retinopathy than those with birth weight equal or more than 2500g( P<0.001). CONCLUSION: The main influencing factors which lead to retinopathy of high risk full-term infants are prenatal factors such as PRH, and some neonatal risk factors such as asphyxia, hypoxic-ischemic encephalopathy, and low birth weight.展开更多

The incidence of infants was 104.66/100,000, which was 118 times higher than in other age groups （P 〈 0.001）. The primary type of pertussis simultaneously presented in households was adult-to-infant （70.51%）. The parents were identified as the source of infection in 80.18% of cases for infants. The positive rate of placental antibody transfer was 31.06% and 3.13% for 3-month-old infants. Infants presented the highest age-specific pertussis incidence. The most important reason was parents were the important sources of infection, and secondly the lower level of antibodies in neonates and the rapid waning of maternal antibody titer.展开更多

Methods: To obtain studies eligible for meta-analysis, China biological medicine discs and MEDLINE citations were surveyed. Mother HBV DNA or HBeAg positivity, neonate HBeAg positivity, mode of delivery, threatened abortion and threatened premature labor were processed with meta analysis. Criteria for selection of published studies for meta analysis were based on principle by Abdolmaleky HM[1]. Odds ratio (OR) was calculated and summarized by fixed effect model or random-effects model using RevMan software. The heterogeneity of the group of ORs was assessed using an x2 test. The significance of the pooled OR was determined by the u-test. The strength of association was assessed using the OR. An OR>1. 0 indicated a positive association between the risk factor and neonate HBV infection. Results: After meta analysis of factors concerned, a significant association was found between the positivity of HBeAg in mother and neonate, of HBV DNA in mother peripheral serum, and HBV mother-to-infant transmission, with a pooled OR equal to 19.43 (95% CI=8. 77-43. 06), 36.5 (95% 01=19.85-67.11), and 36. 5 (95% CI=19. 85-67. 11) respectively. Mode of delivery, threatened abortion and threatened premature labor proved not to be of risk factors on the mother-to-infant transmission of HBV. Conclusion: Mother HBV DNA or HBeAg positivity and neonate HBeAg positivity were proved to be of risk factors affecting the transmission of HBV from mother to fetal.展开更多

The design used was a clinical trial: two eohorts (i.e., 12 and 18 months old children) and three treatment groups (i.e., energy + micronutrient, micronutrient alone, and placebo) per cohort. Every day except Sunday, the infants attended day-care centers. Twenty four centers and 136 infants were selected. The infants were screened for weight and length and those meeting the criteria (i.e., <-1 SD of length-for-age, and between -1 and -2 SD of weight-for-length of the NCHS reference) were included. The experimental unit was the day-care centers (DCC), where each DCC was randomly assigned to one of the three treatment. As expected, groups of energy + micronutrient and micronutrient alone of the 12 months cohort experienced a significant upward shift in hemoglobin, ferritin and TS and a downward change in FEP, while the values for the group of placebo remain about the same as at base line. In the first 6 month of treatments, the ANOVA for each iron indicator yielded significant main effects of treatment (P<0.01) and for Hb with (P =0.059) on 12 months cohort. On the other hand, the main effects of treatment on hemoglobin, TS, ferritin and FEP were not significant for the 18 months cohort. In the second 6 month of treatments, the only significant of the treatment effect (P<0.01) was in serum ferritin on 18-month cohort. Under these circumstances, energy has a positive role in improving iron stores. It is likely that the equilibrium of hemoglobin and each iron indicators were reached in 6 months of treatment except ferritin still continued to increase up to 12 month. The effects of treatment on the improvement of iron status was stronger in 12 months than in 18 months展开更多

文摘目的:初步探讨孕期因素与婴儿牛奶蛋白过敏的关系。方法:数据来自一项“中国儿童对牛奶蛋白过敏的遗传易感性研究”的子队列,包括2020年3月1日至12月31日在北京大学人民医院出生的婴儿,根据随访至1岁时有无牛奶蛋白过敏(cow’s milk protein allergy,CMPA),分为病例组(CMPA组)和对照组。回顾性收集婴儿及其母亲孕前和孕期的临床资料,分析孕期多因素与婴儿牛奶蛋白过敏的相关性。结果:共纳入278例婴儿,CMPA患儿52例,对照组226例;男性婴儿143例,女性婴儿135例,其中男性婴儿在CMPA组比例(69.2%)高于对照组(47.3%),差异有统计学意义(P=0.004);CMPA患儿和对照组在出生体质量、出生胎龄、低出生体重儿、早产、脐带绕颈、新生儿窒息分布上差异无统计学意义(P>0.05)。母亲孕期合并免疫性疾病、贫血者以及孕期存在抗生素暴露者在CMPA组比例均高于对照组,两组之间差异有统计学意义(P<0.05);其他妊娠期合并症,如子痫/子痫前期、慢性高血压/妊娠期高血压、糖尿病/妊娠期糖尿病、甲状腺疾病等在两组分布差异无统计学意义(P>0.05)。CMPA组与对照组孕期多项血常规指标总体分布差异无统计学意义(P>0.05)。多因素Logistic回归分析发现男性婴儿、母亲妊娠合并免疫性疾病、妊娠合并贫血以及孕期抗生素暴露是CMPA发生的独立危险因素。结论:男性婴儿、母亲妊娠合并免疫性疾病、妊娠合并贫血以及孕期抗生素暴露是CMPA发生的独立危险因素。
