Impact of pre-pregnancy body mass index on baby's physical growth and nutritional status / 中南大学学报(医学版)

OBJECTIVE@#To explore the impact of pre-pregnancy body mass index on baby's physical growth and nutritional status.@*METHODS@#A total of 491 pairs of mother-infant were divided into 3 groups according to mother's pre-pregnancy body mass index (BMI): a pre-pregnancy low BMI group (BMI<18.5 kg/m², n=93), a pre-pregnancy normal BMI group (18.5 kg/m² ≤ BMI<24.0 kg/m², n=326), and a pre-pregnancy high BMI group (BMI ≥ 24.0 kg/m², n=72). Analysis of variance of repeated measurement data and the median percentage methods were used to compare the physical growth and nutritional status of babies in different groups.@*RESULTS@#Baby's weight in the high BMI group were higher than that in the normal BMI and the low BMI group (F=3.958, P=0.020). The incidence of malnutrition in the low BMI group showed a tendency to decline along with the months (χ²=5.611, P=0.018), the incidence of overweight and obesity in the high and the normal BMI groups displayed a tendency to decline along with the months (χ²=18.773, 53.248, all P<0.001). Baby in the low BMI group had higher incidence of malnutrition while baby in the high BMI group had higher incidence of overweight and obesity.@*CONCLUSION@#Pregnancy BMI was correlated with the growth of baby. Too high or too low prepregnancy BMI exerts harmful effect on baby's weight and nutritional status. Medical workers should strengthen the education on women's pre-pregnancy to remind them keeping BMI at normal level.

Studies on the Pharmacology of Extracts of Tianshan Mountain Mountainash (Sorbus tianschanica ) / 中草药

It has got good effects that aqueous extracts of Sorbus tianschonica Rupr (AQ-ESTR) used for the treatment of chronic bronchitis, Pulmonary tuberculosis and edema etc in folk medicine. The pharmacological experiment showed that AQESTR had antibechic effect on mice induced by ammonia water, expectorant effect and antiasthmic effect on guinea pig induced by mixture of Ach-histamine. Cardiac Pharmacological experiment also showed AQESTR Produced significant bridycardia in mice. At the dose of 25mg/kg, AQESTR decreascd the heart rate and Prolonged the P-r interval of ECG in vivo, AQESTR decreased the contractive force of isolated atrial muscles rabbits in dose-dependent manner.
