隐性缺铁婴幼儿脑功率谱及脑地形图变化研究

采用严格配对的研究方法，对２０对６～３０个月隐性缺铁（ＬａｔｅｎｔＩｒｏｎＤｅｆｉｃｉｅｎｃｙ，ＬＩＤ）婴幼儿进行了脑功率谱和脑地形图分析。结果显示ＬＩＤ患儿在右后顶部、左中后颈、右中颞及前中央顶部α１能量减低，提示ＬＩＤ患儿大脑发育比正常组婴幼儿落后。

正常儿童粪便中sIgA含量分析

目的　了解正常儿童粪便中sIgA的含量及其与肠道菌群和摄入营养素的关系。方法采取随机整群抽样的方法对农村 3 91名出生至 1 8个月婴幼儿进行调查 ,并对其中 5 5名婴幼儿采用ELISA方法检测粪便中sIgA含量。调查结果采用EPI和SPSS软件进行统计分析。结果儿童粪便中sIgA的含量随着儿童年龄的增长有下降的趋势 ,但无显著性差异 (P >0 0 5 ) ,1岁后趋于平稳 ;母乳喂养量、维生素C的摄入量及双歧杆菌与粪便sIgA含量呈正相关 ;儿童体重、身长与粪便中sIgA含量呈正相关。结论　应加强母乳喂养宣传力度 ,加强乳母的营养 ,保证母乳喂养的质量 ;婴儿出生后要逐渐增加维生素C的摄入 ;在辅食添加时强化双歧杆菌活菌等 ,有利于婴幼儿健康成长     

母亲因素与低出生体重儿的关系

对1986年10月～1987年9月及1989年1月～1989年12月期间出生的365例低出生体重儿,按其母亲情况作回顾调查和分析。低体重儿发生率为7.99%,死亡率15.07%。母亲主要疾病为妊娠高血压综合征和中、重度贫血,经X~2检验均有显著意义。多元逐步回归分析表明母亲为农民、早产、新生儿畸形为最危险因素。文章认为加强围产期保健是降低低体重儿发生的有效措施。     

陕西部分农村社区0～18个月婴幼儿母亲的喂养知识状况及影响因素

目的　掌握陕西省农村社区 0～ 1 8个月婴幼儿母亲喂养知识水平及影响因素的状况。方法　抽取 3 3 7例 0～ 1 8个月婴幼儿母亲进行问卷调查。结果　婴幼儿母亲的喂养知识合格率为 5 7% ,与母亲文化程度、产前检查、产后访视次数、当地村医给予宣传指导等因素相关。结论　进一步证实提高母亲文化程度、增加产前检查、产后访视次数、更新村医的喂养知识及观念 ,是促进母亲掌握喂养知识的关键。     

RESEARCH OF GENETIC POLYMORPHISM OF 5-HTT IN CHILDHOOD AUTISM

Objective To reveal the relationship between the 5-HTTLPR and the Chinese Han nationality children with CA, compared the distribution of the 5-HTTLPR between the Han Chinese children with CA and healthy Han Chinese children , and analyzed the association between the 5-HTTLPR and clinical symptoms of the Han Chinese children with CA. Methods Genomic DNAs of fifty subjects including 25 autistic children and 25 controls were extracted from blood samples. PCR amplification using Oligonucleotide primers flanking 5-HTTLPR was performed. Results① Three kinds of alleles including the S （short） allele, the L （long） allele and the VL allele were found , and the 5-HTTLPR genotypes shown were S/S, L/L, S/L and L/VL. ②Allele frequencies did not differ significantly in patient groups in comparison with the control sample. No significant difference was identified between the observed 5-HTTLPR genotype distribution of the patient groups and control group. ③The distribution of homozygons and heterozygous subjects between the two groups differed significantly. ④ The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor. ⑤ The allele frequency of healthy Han Chinese population and that of healthy Japanese population were similar. The frequency of S allele in not only autistic subjects but also healthy children in this study was considerably more than that in Caucasians and the frequency of L allele in our subjects decreased correspondingly. Conclusion ① A significant difference in the allele frequency between the Han Chinese and Caucasian populations was found. ② The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor of the patients. ③ The homozygote and the L allele were positively relevant to CA and they might be the risk factors of CA. The heterozygote and the S allele were negatively relevant to CA and they might be the protective factors of CA.
