多模态磁共振成像对新生儿缺血缺氧性脑病诊断及预后的研究进展

MRI现已成为新生儿缺血缺氧性脑病(hypoxic-ischemic encephalopathy,HIE)的必备检查方式,但常规MRI检查技术对于早期发现HIE的诊断敏感性较低,与常规MRI相比,多模态MRI成像技术,如弥散加权成像(diffusion weighted imaging,DWI)、弥散张量成像(dif...     

单唾液酸四己糖神经节苷脂治疗新生儿缺氧缺血性脑病临床疗效

目的探讨单唾液酸四己糖神经节苷脂（GM1）治疗新生儿缺氧缺血性脑病的临床疗效。方法：48例新生儿缺氧缺血性脑病患儿,随机分为治疗组25例,对照组23例,两组均采用常规治疗,治疗组在常规治疗基础上加用GM1静脉滴注,1次／天,20mg／次,10～14天为一疗程。比较两组患儿治疗前后新生儿神经行为评分（NBNA）及CT测量值。结果：两组患儿治疗5～7天和治疗10～14天NBNA评分有显著差异．且治疗组评分明显高于对照组。两组患儿治疗前和治疗一疗程CT值均无显著差异（P〉0．05）,出生后28天治疗组CT值明显高于对照组（P〈0．05）。结论：GM1治疗新生儿缺氧缺血性脑病疗效显著,未见不良反应发生。     

新生儿游泳在产科建设中的应用与探讨

目的：为迎接新一轮爱婴医院复审工作做准备,提高本院产科建设的人文文化的氛围和把科学产后延伸服务落到实处。方法：随机抽取446例健康、顺产,产后Apgar评分均在8分以上的住院分娩的新生儿,体重无明显差异（P〈0．05）,平均分为两组,游泳组（即观察组）与对照组,主要对新生儿游泳前后的体重、睡眠质量、日均摄奶量、胎便转黄时间等相关因素进行探讨与研究。结果：新生儿游泳能促进新生儿体重增加、睡眠质量提高、日均摄奶量增多、胎便转黄时间缩短。两组比较差异有统计学意义（P〈0．01）。结论：新生儿游泳对新生儿的身体发育有积极的促进作用。     

Clonality of clinical methicillin-resistant Staphylococcus epidermidis isolates in a neonatal intensive care unit

OBJECTIVE: Study of the clonality of methicillin-resistant Staphylococcus epidermidis responsible of epidemic infections in a neonatal intensive care unit. PATIENTS AND METHODS: All S. epidermidis isolates (mecA+) were collected during the epidemic period (December 2003-September 2004) from different pathological products of newborns. Isolates were characterized by genotyping in pulsed-field gel electrophoresis and by electrophoretic profiles obtained by PCR-based analysis of inter-IS256 spacer polymorphisms. RESULTS: Twenty methicillin-resistant S. epidermidis isolates were collected from newborns during the epidemic period and represented 41.6% of the total isolates of S. epidermidis, which is the first Staphylococcus species isolated from the unit. These isolates were collected from blood cultures (80%), vascular catheters (5%), pus (10%), and intra-tracheal tube (5%). Six genotypic profiles were individualized: type A, type B, type C, type D, type E, and type F, with clear dominance of type A. Five different PCR patterns were found with poor correlation to genotypes defined by PFGE. CONCLUSION: Neonatal nosocomial outbreak of methicillin-resistant S. epidermidis was caused by multiple clones of this species with predominance of one epidemic and multiresistant clone. This clone may be transmitted between babies and was able to persist in the unit. PCR IS 256 proved to be less discriminative than PFGE for typing MRSE.
