Interactive Effects of Early Exclusive Breastfeeding and Pre-Pregnancy Maternal Weight Status on Young Children's BMI - A Chinese Birth Cohort.

Objectives: To assess if the maternal pre-pregnancy weight status (MPWS) alters the association of early infant feeding pattern (at one and third months) with infant body mass index (BMI) in the first two years of life.

Methods: A cohort of 2,220 neonates were recruited in a community-based study conducted in China. Body weight and length were measured at birth, at age one and two, with BMI calculated accordingly.

[Clinical phenotype genotype correlation in children with hemoglobin H disease in Zhuhai area of China].

Objective: Alpha-thalassemia is one of the most common monogene disorders in the world. Most frequently, it is caused by deletions of alpha-globin gene (-alpha or --), and less commonly resulted from the non-deletional mutation (alpha(T)alpha). Hemoglobin H (HbH) disease is the most severe type among survivors of alpha-thalassemia.

[The expression patterns of genes in different biotypes by genome addition].

The patterns of SOD, EST and haemoglobin genes expression among the different combinations conducted with genome addition were investigated. The erythrocyte expression of these isozymes and protein were visualized by histochemical staining after polyacrylamide gradient gel electrophoresis. The results of our electrophoresis analysis have revealed that biochemical polymorphism exists in the combinations, and these genetic variance have resulted from the contribution of different genomes.
