RESUMO

Objective:To investigate the effect of different delivery and feeding modes on intestinal microflora in infants with atopic dermatitis (AD) .Methods:A total of 33 infants with AD were enrolled from Department of Dermatology, Wuhan NO.1 Hospital from July 2019 to December 2020, and 30 healthy infants were selected as control group. Then, all infants were grouped according to different delivery and feeding modes: cesarean-delivery AD group (22 cases) , cesarean-delivery control group (19 cases) , spontaneous-delivery AD group (11 cases) , and spontaneous-delivery control group (11 cases) ; mixed-feeding AD group (13 cases) , mixed-feeding control group (11 cases) , formula milk powder-feeding AD group (12 cases) , formula milk powder-feeding control group (11 cases) , breastfeeding AD group (8 cases) , and breastfeeding control group (12 cases) . The total DNA was extracted from the infant feces, PCR was performed to amplify the V1 - V9 regions of bacterial 16S rRNA gene, and PacBio Sequel sequencer was used for high-throughput sequencing. Wilcoxon rank sum test was used to compare the bacterial community composition at genus and species levels, and correlations of relative abundance of differentially abundant bacterial taxa with eosinophil counts and SCORing Atopic Dermatitis (SCORAD) scores were analyzed.Results:In the spontaneous-delivery control group, cesarean-delivery control group, spontaneous-delivery AD group, and cesarean-delivery AD group, the top 5 bacterial genera with high relative abundance were Bifidobacterium, Bacteroides, Veillonella, Streptococcus, and Escherichia. In the formula milk powder-feeding control group, breastfeeding control group, mixed-feeding control group, formula milk powder-feeding AD group, breastfeeding AD group, and mixed-feeding AD group, the top 5 abundant bacterial genera were Bifidobacterium, Bacteroides, Clostridium, Veillonella, and Escherichia. Linear discriminant analysis of effect size (LEfSe) showed no significant difference in the relative abundance of bacterial taxa among different delivery mode groups; among different feeding mode groups, Akkermansia and Akkermansiamuciniphila were the most differentially abundant microbes in the formula milk powder-feeding AD group at genus (LDA = 4.78) and species (LDA = 4.91) levels, respectively. The relative abundance of Akkermansia and Akkermansiamuciniphila (both 9.6% ± 0.72%) was significantly higher in the formula milk powder-feeding AD group than in the formula milk powder-feeding control group (both 2.50% ± 0.83%, Z = 1.66, P = 0.048) , the mixed-feeding AD group (both 0, Z = 2.26, P = 0.012) and the breastfeeding AD group (both 0, Z = 1.85, P = 0.032) . Additionally, the relative abundance of Akkermansia and Akkermansia- muciniphila was positively correlated with SCORAD scores in AD patients ( ρ = 0.384, 0.387, respectively, both P < 0.05) . Conclusion:Different delivery modes did not significantly affect the intestinal flora of AD or healthy infants, and the relative abundance of Akkermansia and Akkermansiamuciniphila increased in the formula milk powder-feeding infants with AD, which may be involved in the occurrence of AD.

RESUMO

Objective To discuss the influence about three kinds of nasal feeding methods on ICU critical patients with gastrointestinal complications, thus providing guidance for ICU patients to choose reasonable way of nasal feeding pump injection. Methods 120 ICU patients were randomly assigned into three groups, which is the continuous 6-hour and intermittent 2-hour every three time pump group and continuous 24-hours pump group and intermittent 24-hour(continuous 2-hour and intermittent 1-hour every eight time units)pump group ,each group has 40 cases. To observe the the influence about three different way of nasogastric on ICU critical patients with gastrointestinal complications. Results The incidence of diarrhea and constipation among the three groups was not statistically significant (P>0.05) . The gastric retention rate of the continuous 24-hour pump group was significantly higher than that of the continuous 6-hour and intermittent 2-hour pump group and the intermittent 24-hour pump group, the differences were statistically significant (P 0.05). Conclusions The continuous 24-hour pump group in gastric retention was slightly worse than the other two pump way. Compared with ICU class three a week and feeding times , the continuous 6-hour and intermittent 2-hour pump method is more suitable for ICU patients.

RESUMO

Objective To review and analyze the causes of infant malnutrition and its relation with the way of feed.Methods Infant malnutrition was analysed with the emphasis on pathogeny,the onset month of the birth, its complication and clinical reflection in 63 cases.Results Infant malnutrition occurred in the case with incorrect feeding way:feeding on low protein powdered milk or cereals untimely without considering the supplementary food. Malnutrition easily brought out other kinds of disease.Conclusion It is recommended that infants younger than 5 months should be fed on breast-milk.In case of no breast-milk or short,dairy products are introduced,especially in- fant formula,with adding supplementary food timely.If not so,infant malnutrition occurs.
