目的 观察以湿敷为主的早期综合干预疗法治疗婴幼儿湿疹的效果。方法 按照随机的原则对118例患有湿疹的婴幼儿分为观察组(60例)和对照组(58例)。观察组采取以湿敷为主的早期综合治疗,对照组采取一般家庭干预,两组均跟踪随访,观察湿疹的好转情况,并统计湿疹复发率。结果 观察组60例患者中痊愈38例,占 63.3%;显效20例,占 33.3%;有效2例,占3.3%;无效0例;总有效率100%。痊愈的38例中,随访8周后重新出现湿疹的病例为8例,复发率为21%。对照组58例患者中痊愈20例,占 34.48%;显效14例,占24.14%;有效16例,占27.59%;无效8例,占13.79%;总有效率86.21%。观察组痊愈的38例中,随访8周后重新出现湿疹的病例为8例,复发率为21%。对照组痊愈20例中复发6例,复发率为30%。结论 以湿敷为主的早期综合干预疗法能有效减轻湿疹的症状,可以作为社区治疗婴幼儿湿疹的参考。

Objective To observe the effects of wet compress based early comprehensive intervention therapy in the treatment of infant eczema. Methods 118 cases of infantile eczema within the jurisdiction were randomly divided into observati on group (60 cases)and control group (58 cases). The observation group was given early comprehensive therapy based on wet compress while the control group took general family intervention.Follow-up observations were adopted for both groups to examine the curing of eczema and to collect data for eczema recurrence. Results In the observation group of 60 cases, 38 were cured, accounting for 63.3%; 20 markedly improved (33.3%),2 effective(3.3%) and 0 ineffective; with the total effective rate of 100%.of the 38 cases cured, eczema reappeared in 8 cases after eight weeks of follow-up observation, with the recurrence rate of 21%. In the control group of 58 cases, 20 were cured, accounting for 34.48%; 14markedly improved (24.14%), 16 effective (27.59%),and 8 ineffective (13.79%),with the total effective rate of 86.21%. In the observation group, eczema recurred in 8 of the 38 cured cases after eight weeks of follow-up observation, with the recurrence rate of 21% while in the control group, eczema recurred in 6 cases, with the recurrence rate of 30%. Conclusion Wet compress based early comprehensive intervention therapy can effectively relieve the symptoms of eczema, so it can be effectively used in community treatment of infantile eczema.

目的 了解CHPS患儿经胃镜下幽门肌切开术治疗后幽门部黏膜近期各种并发症的发生情况及对预后的影响。方法 选取2006—2012年我院新生儿科确诊的34例CHPS患儿。以超细胃镜进入十二指肠乳头处,使用电切刀按上行性方向,沿幽门管纵轴切割肥厚狭窄的幽门管黏膜及环形肌以解除幽门部梗阻。术后第1、3、6月复查胃镜。结果 34例CHPS患儿共行胃镜下幽门肌切开术48次,均未发生胃及幽门穿孔、撕裂等严重并发症。24例患儿术后通过胃镜进行了复查,胃镜见幽门部及黏膜改变主要有黏膜充血肿胀、切口未完全愈合、切口疤痕形成、幽门部息肉形成等。结论 经胃镜下幽门肌切开术是一种安全性较高的治疗CHPS的新技术。术后黏膜充血肿胀、切口未完全愈合等幽门部黏膜改变的发生率随时间下降。切口疤痕形成并未影响幽门功能。

        目的   探讨出生胎龄＜37周早产儿发生败血症时的临床特征及其不良结局的危险因素。方法   收集2020年1月—2023年12月安徽医科大学第一附属医院本部新生儿科收治出生胎龄＜37周且发生败血症早产儿的临床资料；根据败血症发生时间分为早发型败血症（EOS）49例，晚发型败血症（LOS）150例；根据是否出现不良结局，分为结局不良组90例，结局良好组109例。分析EOS和LOS败血症的临床特征，并采用多因素Logistic回归分析早产儿败血症出现不良结局的危险因素。结果  早产儿败血症中EOS患儿出生胎龄更小，生后1 min Apgar评分更低，孕母羊水污染、胎膜早破≥18 h发生率较LOS更高（P＜0.05）；早产儿败血症临床表现无特异性，但LOS患儿休克发生率更高（P＜0.05）；早产儿易发生革兰阴性菌感染，合并先天性心脏病（OR=2.490，P＜0.05）、出生胎龄＜30周（OR=4.851，P＜0.05）、出生体质量小于1 500 g（OR=4.169，P＜0.05）是早产儿败血症发生不良结局的危险因素。结论  早产儿败血症临床表现无特异性，更易发生革兰阴性菌感染，出生胎龄越小、体质量越低发生不良结局的风险更高。

       目的  探讨晚期早产儿中小于胎龄儿（SGA）与适于胎龄儿（AGA）出生时的铁代谢状态。方法  选取2020年1—12月合肥市妇幼保健院收治的150例晚期早产儿（胎龄34～36⁺⁶周）作为研究对象。按照出生体质量和胎龄将早产儿分为SGA组（36例）和AGA组（114例），分析比较两组早产儿出生时的铁代谢状态，并应用多因素线性回归分析血清铁的影响因素。结果  与AGA组相比，SGA婴儿的更低的血清铁［14.5 μmol /L （11.4，17.1） vs 16.4 μmol /L（14.1，18.4），P=0.004］、更低的血清铁蛋白［135.6 μg/L（101.8，176.2） vs 172.5 μg/L（123.0，218.3），P=0.009］和更低的总铁结合力［30.4 μmol/L（26.8，34.9）vs 35.4 μmol/L（29.5，44.6），P=0.001］。两组早产儿的血红蛋白、平均红细胞体积、平均红细胞血红蛋白含量和平均红细胞血红蛋白浓度比较差异均无统计学意义（P＞0.05）。在早产儿围生期特征中，胎盘异常（β= –1.949，P=0.009）和母亲糖尿病的发生（β= –2.324，P=0.001）与血清铁水平呈负相关。结论  与早产AGA相比，早产SGA铁储备水平较低，适量补充铁元素对小于胎龄新生儿身体发育有促进作用。

       目的    探究经鼻间歇正压通气（NIPPV）和经鼻持续正压通气（NCPAP）作为早产儿呼吸窘迫综合征气管插管机械通气拔管后无创呼吸支持过渡的临床效果的差异。方法   纳入2021年1月—2023年6月在广东省吴川市妇幼保健计划生育服务中心治疗的新生儿呼吸窘迫综合征早产儿66例，用随机数字表法将患儿分为NIPPV组（33例）和NCPAP组（33例）。NIPPV组患儿予经鼻间歇正压通气作为过渡期无创呼吸支持，NCPAP组患儿则予以经鼻持续正压通气作为过渡期无创呼吸支持。对比两组患儿治疗前后血气分析结果、脱机失败率、无创呼吸支持时间、无创后吸氧时间、总给氧时间等指标。结果  接受无创呼吸支持12 h后，NIPPV组患儿的PaO₂升至（76.46±1.10）mmHg，高于NCPAP组患儿的（75.51±2.15）mmHg（t=2.249，P=0.028）。此外，NIPPV组患儿的SaO₂升至（96.36±0.52）%，也高于NCPAP组患儿的（96.07±0.59）%（t=2.138，P=0.034）。而NIPPV组患儿的PaCO₂则降至（41.39±0.74）mmHg，较NCPAP组患儿的（41.87±0.95 ）mmHg低（t=-2.230，P=0.025）。NIPPV组无创呼吸支持时间为（3.09±0.52）d，短于NCPAP组的（3.45±0.62）d，且该差异有统计学意义（t=2.584，P=0.012）。同样的，NIPPV组总给氧时间（9.52±0.76）天较NCPAP组的（10.00±0.79）天短，且该差异有统计学意义（t=-2.548，P=0.013）。而两组在脱机失败率、无创呼吸支持后吸氧时间、不良反应发生率等方面比较差异无统计学意义（均P＞0.05）。结论   与NCPAP模式相比，早产儿拔管后应用NIPPV模式进行无创呼吸支持取得的临床效果更优。
