Although breast feeding has long been proved to be the best way tor infant feeding, for many reasons, however, the number of breast-fed infants were always fewer than those of artiticially or mixed fed ones either in urban or in rural, e.g. it was found that only 35.7% of infants aged 4 months in Shanghai were breast-fed in 1980. Therefore manufacturing some kinds of humanized milk for improving infant nutrition seems necessary.A humanized milk powder was manufactured in Hongyuan Powdered Milk Factory. For testing its suitability for infant nutrition, a feeding experiment in infants was conducted in our laboratory in spring 1982.75 healthy babies aged 1-5 months were equally randomly assigned into three groups, i. e. humanized milk group, breast feeding group, and cow's milk group. The other food supplements except the milks were same in all groups.All the babies were subjected to anthropometric examination and blood hemoglobin determination before and after the 3 months' experimental period.Experimental results showed that there was no significant difference between the three groups either in growth and development or in blood hemoglobin level.In addition, Hongyuan humanized milk powder was also found to be more digestible and acceptable for the majority of the tested infants.

In the present work the relative biological availability (RBA) of iron in the blood and the liver paste of swine has been studied by means of the hemoglobin regeneration technique in chickens. One day-old chickens were first made anemic on a low iron basal diet for 3 weeks, and were then divided into groups to which basal diets with various iron levels (10, 20, 40 ppm Fe) from different iron sources (ferrous sulfate reference standard, whole blood meal of swine and liver paste of swine) were subsequently fed respectively.After 16 days on test diets hemoglobin levels and hematocrit values in the blood of the chickens were measured. The chickens were then sacrificed for measurement of the iron concentration in their livers.Regression lines of each iron source were fitted by plotting final hemo- globin concentrations against the corresponding iron concentrations of the diet fed. Let the slope of the regression line from ferrous sulfate be 100, (i.e. relative bioavailability of ferrous sulfate), the RBA of the other 3 iron sources was as follows; processed whole blood meal of swine was 90.2; raw blood meal of swine 64.6; and the live paste of swine 78.4; but the differences between any two of them are statistically non-significant; i.e. their effects on hemoglobin regeneration are of the same extent.

Objective To investigate differential expression of Raf kinase inhibitor protein (RKIP)in gastric cancer and its clinical significance.Methods Pure gastric adenocarcinoma cells (GAC)and paracancerous gastric epithelial cells(NGEC)in 12 patient with gastric cancer were obtained using laser capture microdissection(LCM).After trypsin digestion all specimens were labeled with18O/16O.Quantitatively identification of differentially expressed proteins between GCC and NGEC was conducted using Nano-HPLC-MS/MS.The expression of RKIP in GAC was determined by Western blotting.Immunohistochemistry(IHC)was used to detect the expression of RKIP in gastric cancer(n=118),non-cancerous mucosa tissues(n=70)and matched positive lymph node tissues(n=35).Results A total of 78 differentially expressed proteins were identified and RKIP was downexpressed in GCC compared with NGEC(1:4.37).IHC examination revealed that positive expression of RKIP in gastric cancer had negative relation with deeper invasion,TNM stage and lymphoid node metastasis,while it had positive relation with histological differentiation(P＜0.05).Conclusion Down-regulation of RKIP in gastric cancer tissues might affect the biological behavior of gastric cancer.

With food containing konjac flour, a 45-day-long feeding trial on 110 old people suffering from hyperlipidemia was conducted to observe the effect of konjac food on lipid metabolism of human beings.The konjac flour was from Amorphophallus konjac, a kind of traditional food, with trace protein and very low energy, but rich in dietary fibre composed mainly of gluco-mannan.The results obtained were as follows;1.After having konjac flour 5g/day as a supplement of their regular meal for 45 days, concentration of TG, TC and LDLC in the serum of the experimental subjects decreased significantly (P

In the present article the effects of animal blood and liver on the status of iron nutrition in preschool children were studied.71 apparently normal children in a kindergarten, aged 3-7 years, were selected for feeding trial. All of them were undergone physical examination to verify the absence of hookworm infestation and chronic diseases, but having a bit lower hemoglobin concentration (Hb
