Chinese Journal of Information on Traditional Chinese Medicine 2015;(5):20-24
Objective To investigate the relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents;To provide basis for the targeted interventions for couples of childbearing age before pregnancy-periconceptional TCM constitution. Methods Compiling scales for pregnant couple’ TCM constitution type assessment and postpartum visits to newborns, the research team got access to the information of neonatal physical problems, constitutions and changes of 675 babies’ father and mother who had established maternal manual from April, 2012 to March, 2013 at the Sanlin Community Health Center of Pudong District of Shanghai. Results Early to mid-pregnancy expectant parents mainly had peace constitution type. In detail, 55% of pregnant women had gentle constitution type, while others mainly had qi deficiency, yang deficiency and damp-heat constitution types;76% expectant fathers got peace constitution, while others mainly got damp-heat, yin deficiency and qi deficiency constitution types. Marital pregnancy physique did not change significantly. Compared with the peace constitution type, newborns, whose fathers got damp-heat constitution type, had higher risk of jaundice, and whose mothers got yin deficiency, the babies had higher risk of spits (P<0.05). The constitution types of expectant parents did not have obvious combined action on neonatal health. Conclusion There is a certain relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents. It is necessary to distinguish constitution types of prospective parents, and thus to take targeted health interventions.

9.Effects of sodium salicylate on the expression of HSP27 protein during oxidative stress in tissue-cultured human lens epithelial cells.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2006;26(6):753-5
The effects of sodium salicylate on the expression of heat shock protein 27 (HSP27) during oxidative stress in tissue-cultured human lens epithelial cells were investigated. Cultured human lens epithelial cells (HLB-3) were divided into 3 groups: control group (group A), oxidation injury group (group B) and sodium salicylate group (group C). Apoptosis of human lens epithelial cells cultured in vitro was induced in the presence of 150 micromol/L H2O2. Cells viability and the expression of HSP27 were analyzed. Viability of the cells was measured by methyl thiazole tetrazolium (MTF) chromatometry. The expression of HSP27 in HLB-3 cells was detected by using immunohistochemistry and image analysis system. Sodium salicylate could induce the expression of HSP27, and the cells viability in group C was significantly higher than in group B (0.2667+/-0.01414 vs 0.2150+/-0.01080, P=0.012<0.05). The average gray value of HSP27 in group B was less than that in group C (P=0.000<0.05). The increased expression of HSP27 by sodium salicylate might play an important role in the protection of hydrogen peroxide-induced injury of human lens epithelial cells, suggesting that sodium salicylate could suppress, at least in part, the apoptosis of human lens epithelial cells.
