Influence of maternal and infant factors on CD34 / 中国当代儿科杂志

OBJECTIVE@#To study the association of different maternal and infant factors with the number of total nucleated cells and CD34@*METHODS@#A prospective study was performed for the umbilical cord blood samples of 130 neonates who were born in Dalian Women and Children's Medical Center from June 2019 to January 2020, with a male/female ratio of 1:1. Related perinatal information was collected, including maternal age and blood type, presence or absence of gestational diabetes or gestational hypertension, pregnancy method, mode of delivery, singleton pregnancy/twin pregnancy, body weight and sex of neonates, Apgar score after birth, and the conditions of placenta, amniotic fluid, and umbilical cord.@*RESULTS@#The neonates were grouped according to maternal blood type, gestational diabetes, gestational hypertension, pregnancy method, mode of delivery, singleton pregnancy/ twin pregnancy, sex of neonates, Apgar score after birth, placental morphology, meconium staining of amniotic fluid, and umbilical cord around the neck. The comparison between groups showed no significant differences in the numbers of total nucleated cells and CD34@*CONCLUSIONS@#The number of CD34

<p><b>OBJECTIVE</b>To investigate the risk factors for capillary leak syndrome (CLS) in children with malignant hematologic diseases.</p><p><b>METHODS</b>Thirty children with hematological malignancies complicated with CLS were analyzed with multiple logistic regression analysis.</p><p><b>RESULTS</b>At the test level of 0.05, hypoxemia and septicemia were found to significantly correlate with CLS in these children, and the number of white blood cells before CLS and severe bone marrow suppression were near the test level.</p><p><b>CONCLUSION</b>Hypoxemia and septicemia are risk factors for CLS in children with malignant hematologic diseases.</p>

N-Acetylcysteine Improves Pancreatic Microcirculation and Alleviates the Severity of Acute Necrotizing Pancreatitis

BACKGROUND/AIMS: To investigate the beneficial effect of N-Acetylcysteine (NAC) on pancreatic microvascular perfusion in acute necrotizing pancreatitis (ANP). METHODS: Fifty-four rats were divided into a control group, an ANP group and an NAC-treated group. The ANP model was established by a retrograde injection of 3% sodium taurocholate into the pancreatic duct. The NAC-treated group received an intravenous infusion of NAC just 2 hours before and 30 minutes after the induction of ANP. The pancreatic microvascular perfusion was measured with laser Doppler flowmetry and pancreatic samples were collected for histological examination. RESULTS: The microvascular perfusion in the NAC-treated group decreased slightly and exhibited a significant increase compared to the ANP group (p<0.01). A pathological examination revealed that edema and inflammatory infiltration decreased, and the hemorrhaging and necrosis of the pancreas were significantly reduced. CONCLUSIONS: NAC could improve pancreatic microvascular perfusion and alleviate the severity of sodium taurocholate-induced ANP, possibly representing a new therapeutic approach to prevent the progression of ANP.
