A nutrition survey of 170 pregnant women of the Han, Miao and Buyi nationality in the middle and late pregnancy was conducted in 1984. The survey included dietary survey, physical and obstetrical examination, biochemical analysis and measurement of weight and height of the newborns of the women studied. The results showed that their calorie intake was substantially suficient to the RDA but the protein intake was inadequate. The proportion of high quality protein was more than 30% of total protein intake for the Han, but less than 25% for the other two nationalities. The calcium and vitamin B2 intakes were much lower than RDA for all the women studied. The retinol intake was only about 73% of RDA for the Han in the late pregnancy. The incidence of nutritional anaemia was 26.92-50.00% among the 170 pregnant women. The weight-height of the newborns has no significant difference among three nationalities and all indices of physical development status were in medium rank on an average.

Objective To compare the myocardial protective effect of warm and cold blood cardioplegia during open heart surgery with cardiopulmonary bypass ( CPB) . Methods Thirty patients with congenital heart disease undergoing open heart surgery under CPB were randomly divided into warm and cold blood cardioplegia groups. In both groups the ratio between oxygenated blood and cardioplegic solution was 4 : 1. In warm blood cardioplegia group the heart was perfused with warm blood (35℃) mixed with high-potassium cardioplegic solution as soon as the aorta was cross-clamped until cardiac arrest developed (flat baseline on ECG). Then the heart was perfused with cold blood (4-81) mixed with low-potassium cardioplegic solution 10 ml?kg-1 every 20 min during ischemic period. At the end of CPB warm blood without potassium was again used to perfuse the heart. Venous blood samples were taken 0.5 h before operation, at the end of operation (T1) and 3 h, 1, 3 and 6 days (T2-5) after surgery for determination of plasma concentrations of CK-MB, cTnI, TNF-?, IL-6 and IL-10. The rate of spontaneous recovery of heart beating was compared between the two groups. Results The two groups were comparable with respect to the demographic data and CPB time. The rate of spontaneous recovery of heart beating was significantly higher and the duration of postoperative mechanical ventilation and ICU stay were significantly shorter in the warm blood cardioplegia group than in cold blood group. The plasma levels of CK-MB, cTnl, TNF-?, IL-6 and IL-10 increased significantly after operation as compared to the baseline (T0) in both groups. The plasma concentrations of cTnl, CK-MB, TNF-? and IL-6 were significantly lower after operation while plasma IL-10 level was significantly higher at T3-4 in warm than in cold blood cardioplegia group ( P
