Clinical characteristics and risk factors for early-onset necrotizing enterocolitis in preterm infants with very/extremely low birth weight北大核心CSCD

Objective To investigate the clinical characteristics and risk factors for early-onset necrotizing enterocolitis (NEC) in preterm infants with very/extremely low birth weight (VLBW/ELBW). Methods A retrospective analysis was performed on the medical data of 194 VLBW/ELBW preterm infants with NEC who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. These infants were divided into early-onset group (onset in the first two weeks of life; n=62) and late-onset group (onset two weeks after birth; n=132) based on their onset time. The two groups were compared in terms of perinatal conditions, clinical characteristics, laboratory examination results, and clinical outcomes. Sixty-two non-NEC infants with similar gestational age and birth weight who were hospitalized at the same period as these NEC preterm infants were selected as the control group. The risk factors for the development of early-onset NEC were identified using multivariate logistic regression analysis. Results Compared with the late-onset group, the early-onset group had significantly higher proportions of infants with 1-minute Apgar score ≤3, stage III NEC, surgical intervention, grade ≥3 intraventricular hemorrhage, apnea, and fever or hypothermia (P<0.05). The multivariate logistic regression analysis showed that feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, and hemodynamically significant patent ductus arteriosus were independent risk factors for the development of early-onset NEC in VLBW/ELBW preterm infants (P<0.05). Conclusions VLBW/ELBW preterm infants with early-onset NEC have more severe conditions compared with those with late-onset NEC. Neonates with feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, or hemodynamically significant patent ductus arteriosus have a higher risk of early-onset NEC. © 2023 Xiangya Hospital of CSU.

Abstract：

Objective To investigate the abnormal expression of microRNA (miRNA)-25 in the serum of gastric cancer patients and its clinical significance. Methods In Xijing Hospital of Digestive Diseases,Fourth Military Medical University,86 gastric cancer patients with operation and completed follow-up data,70 gastric adenoma patients and 80 healthy controls were selected as study objects.Total RNA was isolated from the serum. After the stable and sensitive miRNA-25 absolute quantity detection method established,the serum levels of miRNA-25 in gastric carcinoma patients,gastric adenoma patients and healthy controls were tested according to this method. The expression differences of miRNA-25 in the serum of patients with gastric cancer and gastric adenoma and healthy controls were analyzed with statistic analysis,and the correlation between miRNA-25 expression level and clinic pathological features of gastric cancer was also analyzed. Results The expression level of miRNA-25 in the serum of gastric cancer patients (135. 6 fmol/μg total RNA) was significantly higher than that of gastric adenoma patients (67. 7 fmol/μg total RNA) and healthy controls (62. 2 fmol/μg total RNA)(P＜0. 01). The receiver operating characterisstic curve of miRNA-25 indicated that serum miRNA-25 with good specificity and sensitivity in gastric cancer diagnosis (AUC=0. 827). The serum level of miRNA-25 in gastric cancer patients with lymph node metastasis [(148. 3±10. 2) fmol/μg total RNA] or clinicopathological stage Ⅲ /Ⅳ patients [(146. 7±9.5) fmol/μg total RNA] was significantly higher than that of gastric cancer patients without lymph node metastasis [(120. 3±10. 1)fmol/μg total RNA] or clinicopathological stage Ⅰ/Ⅱpatients [(119. 4±12. 2) fmol/μg total RNA] (P＜0.05). The correlation statistical analysis result indicated that there was no significant difference in survival period between serum miRNA-25 highly expressed and lowly expressed gastric cancer patients (P＞0. 05).Conclusion Serum miRNA-25 testing maybe helpful in diagnosis and prognosis of gastric cancer.

免疫抑制酸性蛋白与HLA－Ⅰ类分子在胃癌组织中的表达及其关系

本文应用抗ＨＬＡ－Ⅰ类重链单态决定簇和抗免疫抑制酸性蛋白Ⅱ型（ＩＡＰ－２）单克隆抗体，分别对６４例胃癌、癌旁组织和６例正常胃粘膜冰冻和石蜡切片进行了免疫组化分析。结果表明，正常胃粘膜及癌旁上皮细胞ＩＡＰ－２表达阴性，ＨＬＡ－Ⅰ类分子表达阳性。但在胃癌组织Ⅰ类分子表达缺失（４２．２％），ＩＡＰ－２表达阳性（９０．５％）。其中肿瘤分化程度与Ⅰ类分子缺失和ＩＡＰ－２高表达均呈负相关，即分化程度越低，Ⅰ类分子缺失率越高，ＩＡＰ－２表达阳性率亦越高。提示：①ＨＬＡ－Ⅰ类分子表达缺失可能是胃癌细胞逃避宿主免疫监视而得以生长、扩散和转移的机理之一；②ＩＡＰ－２的高表达可能是胃癌细胞引起宿主免疫抑制的重要因素。
