目的 研究以尼尔·诺丁斯关怀理论为基础的全程护理在病毒性脑炎（VE）患儿中的干预效果。方法 选取我院2020年4月—2022年4月收治的VE患儿88例,以随机抽签法分为对照组（44例）、观察组（44例）,对照组采用常规护理,观察组在此基础上实施以尼尔·诺丁斯关怀理论为基础的全程护理。比较2组治疗依从性、恢复情况、儿童抑郁障碍自评量表（DSRSC）、儿童焦虑性情绪障碍筛查表（SCARED）、生存质量[儿童生存质量普适性核心量表（PedsQLTM4.0）]及家属护理满意度。结果 观察组治疗依从性100.00%（44/44）高于对照组86.36%（38/44）（P<0.05）;干预后,观察组DSRSC、SCARED评分低于对照组,PedsQLTM4.0评分高于对照组（P<0.05）;干预后,观察组FMA、MMSE评分较对照组升高（P<0.05）;观察组家属护理满意度97.93%（43/44）高于对照组81.82%（36/44）（P<0.05）。结论 以尼尔·诺丁斯关怀理论为基础的全程护理可改善VE患儿心理状态,提高治疗依从性,促进身体康复,进而提高患儿生存质量及家属护理满意度。

目的 通过对43种融合基因在儿童白血病中的结果分析,探讨融合基因阳性的儿童急性B淋巴细胞白血病(acute B-lymphoblastic leukemia,B-ALL)的免疫表型特征。方法 应用实时荧光探针PCR法对2016年10月—2018年12月在深圳市儿童医院就诊的初发或复发B-ALL患儿进行融合基因检测,采用多参数流式细胞术(flow cytometry,FCM)对B-ALL患者进行免疫表型检测。结果 120例B-ALL患儿融合基因筛选总阳性率为37.5%(45/127),包括TEL/AML1 27例、E2 A/PBX1 7例、BCR/ABL1 6例、MLL 4例、TLS/ERG 1例;不同年龄段白血病融合基因阳性率差异有统计学意义(P<0.01),性别分布差异无统计学意义(P>0.05)。各融合基因阳性组CD19阳性率为100%,TEL/AML1阳性表达患者普通-B-ALL表型占比最高(77.8%),干/祖细胞抗原CD34的阳性率为81.5%;E2 A/PBX1阳性表达患者以前-B-ALL表型为主,不表达已知的T系及髓系抗原;各融合基因阳性组及阴性组患儿髓系抗原阳性率比较差异有统计学意义(P<0.01),以BCR/ABL1基因表达组阳性率最高(100%)。结论 5种融合基因在患者年龄构成及免疫表型中具有一定的分布特点;B-ALL特征性免疫表型的改变可用于融合基因表达的预测,提高融合基因结果判读的准确率。

Objective To investigate the immunophenotype features of children with acute B-lymphoblastic leukemia(B-ALL) combined with fusion gene expressing after to analyze the results of the 43 fusion genes. Methods Real-time fluorescent probe PCR assay was used for the detection of fusion genes in 120 cases of children from Shenzhen Children's Hospital with B-ALL newly or recurrently diagnosed from Oct 2016 to Dec 2018. Multi-parameter flow cytometry(FCM) was used for the detection of the immunophenotype in children with B-ALL. Results Of all the 120 cases, the fusion genes were detected at positive rate of 37.5%(45/120), included TEL/AML1 27 cases, E2 A/PBX1 7 cases, BCR/ABL1 6 cases, MLL 4 cases, TLS/ERG 1 cases. The positive rate of leukemia fusion gene had statistically difference among fusion genes positive groups based on age(P<0.01). There was no statistically difference in the gender distribution(P>0.05). The expressing of CD19 was at positive rate of 100% in all of the groups. The rate of the common-B-ALL was the highest B-ALL subtype in the TEL/AML1 positive groups(77.8%). The stem /progenitor associated antigen CD34 was at positive rate of 81.5%. The pre-B-ALL was the main subtype in the E2 A/PBX1 group, which was no expression of the known T-ALL associated antigen MyAg antigen. There was statistically difference in the positive rate of MyAg expression among all of the groups(P<0.01), with the highest rate in the BCR/ABL1 group(100%). Conclusion There were certain distribution features in age composition and immunophenotype of children with B-ALL carrying five kinds of common fusion genes. The characteristic changes of the immunophenotype of B-ALL may be used to predict the expression of fusion genes and improve the accuracy of fusion genes by the supplementary role of immunophenotype analysis.
