鸟巢式护理模式对早产儿生长发育及肠胃功能的影响

目的 探讨鸟巢式护理模式在早产儿护理中的应用价值。方法 选取2016年6月—2020年5月本院收治的早产儿94例,采用随机数表法将其分为两组,每组各47例。对照组给予早产儿采取常规护理,观察组在早产儿常规护理上实施鸟巢式护理模式。比较两组临床效果、护理前后生长发育情况、肠胃功能及家属护理满意度。结果 观察组体温波动幅度低于对照组,睡眠时间长于对照组,血氧饱和度高于对照组,出暖箱时间短于对照组,差异有统计学意义(P<0.05)。护理前,两组头围、身高、体质量比较,差异无统计学意义(t=0.381,P=0.704、t=0.211,P=0.833、t=1.472,P=0.144);护理后2周,观察组头围(28.44±1.35)cm、身高(44.86±2.05)cm、体质量(2 336.93±12.47)g,高于对照组的(27.76±1.87)cm、(42.46±2.43)cm、(2 310.14±13.56)g,差异有统计学意义(t=2.021,P=0.046、t=5.175,P<0.001、t=9.970,P<0.001);观察组首次胎便时间、胎便转黄时间分别为(21.74±7.35)h、(58.91±12.44)h,短于对照组的(25.02±8.13)h、(63.87±13.74)h,排便次数及进奶量的增加分别为(5.67±1.32)次/d、(3.38±1.43)mL/d,高于对照组的(4.21±1.84)次/d、(2.13±0.27)mL/d,差异有统计学意义(t=2.052,P=0.043、t=4.420,P<0.001、t=2.205,P=0.030、t=5.889,P<0.001);观察组护理总满意度高于对照组,差异有统计学意义(P<0.05)。结论 鸟巢式护理模式可减少早产儿体温波动幅度,提供适宜的恒温环境,促进早产儿生长发育,效果确切,值得广泛应用。     

新化合物Elixir-X对肝切及辐射所致衰老小鼠的抗衰老作用

目的 探讨蜂巢提取物Elixir-X对自然衰老及辐射衰老小鼠的影响，为Elixir-X的进一步研发提供药理学基础。方法 采用小鼠肝脏切除术建立自然衰老小鼠模型，将其分为空白对照组、Elixir-X组、白藜芦醇组及模型组，连续给药7 d后，检测小鼠70%肝脏切除后的再生过程中，衰老细胞、肝脏功能恢复与肝脏再生的变化，观察Elixir-X对自然衰老的影响；采用60CO辐射法建立辐射衰老小鼠模型，将其分为模型组、空白对照组、白藜芦醇组、Elixir-X高、低剂量组，通过检测小鼠肠隐窝干细胞再生、小肠绒毛结构以及衰老细胞的变化，对比不同剂量Elixir-X对辐射后衰老的影响。结果 在肝脏切除术的小鼠模型中，Elixir-X组的肝功能水平明显低于模型组的肝脏自然再生小鼠，显著促进了肝功能恢复（P＜0.05）；同时与模型组相比，Elixir-X组清除了肝脏切除后再生过程中产生的衰老细胞（P＜0.05），Ki-67的着色斑块明显增加，促进肝脏的再生，且肝血窦的扫描电镜影像结果中Elixir-X组肝血窦再生加快。60CO辐照小鼠模型中，与模型组相比，Elixir-X组有效促进辐照后肝脏功能恢复（P＜0.05），Elixir-X高剂量组体重也恢复到正常水平，与空白对照组无显著差异；与模型组相比，Elixir-X低剂量组小肠的β-Gal着色细胞减少，Elixir-X高剂量组甚至能更有效地减少衰老细胞（P＜0.05）；小肠HE染色的结果中，Elixir-X组小肠绒毛结构得到恢复；Ki-67的IHC染色中，与模型组相比，Elixir-X组着色板块更多，且着色区域都在肠隐窝干细胞位置。结论 Elixir-X能有效清除肝脏切除术引起的自然衰老与辐射引起的损伤性衰老细胞，对衰老具有显著地抑制作用。     

Implementation of a nurse-led family centered engagement intervention for caregivers of extremely premature infants in the neonatal intensive care unit

ObjectiveThe objective of this feasibility study was to examine the implementation and usefulness of an intervention for extremely premature infant (EPI) caregivers.ResultsOne caregiver and five nurses provided feedback with a mean score of 4.4 out of 5 pertaining to helpfulness.ConclusionsImplementation of the Caregiver's Guide was feasible and was positively received by NICU nurses and caregivers. We recommend implementing a revised version of this tool based on nurse and caregiver feedback. The delivery of education should be divided between dayshift and nightshift nurses so that one nurse is not responsible for providing all the information. The education should be categorized by gestational age and day of life and only given when it is pertinent to the care of the child. A section should be added to include a quick reference guide for the medical jargon used in the NICU.     

层流洁净新生儿重症监护病房早产儿实施床旁手术的可行性分析

 目的 探讨层流洁净新生儿重症监护病房(NICU)早产儿实施床旁手术的效果与可行性。方法 回顾性分析某军队三甲综合医院2017年9月—2020年10月NICU住院并进行床旁动脉导管扎闭术(PDA)及腹部探查术的危重新生儿的临床资料,在NICU行床旁手术者列为NICU组,转入手术室进行手术者列为手术室(OR)组,比较两组新生儿术后体温、切口感染率及病死率的差异。结果 共计纳入258例新生儿,其中NICU组166例,OR组92例。NICU组新生儿出生胎龄、出生体质量、手术时体质量、新生儿危重病例评分均低于OR组;NICU组新生儿术前应用呼吸机通气比例高于OR组,差异均有统计学意义(均P＜0.05)。NICU组与OR组新生儿术中抽检空气培养微生物菌落数、术前体温、PDA与剖腹探查术的构成比例、术后切口感染发病率及病死率比较,差异均无统计学意义(均P＞0.05),但手术后OR组新生儿平均体温低于NICU组,差异有统计学意义(P＜0.05)。结论 层流洁净NICU早产儿行床旁PDA和腹部手术临床可行,且床旁手术更有利于减少术后低体温的发生。对层流洁净病房进行日常规范化维护,可以有效保障危重早产儿床旁手术的安全。

Shortcomings on genetic testing of Familial hypercholesterolemia (FH) in India: Can we collaborate to establish Indian FH registry?

Familial hypercholesterolemia (FH) is a common autosomal dominant disorder that affects ～1 in 250–500 individuals globally. The only prevalence study in India shows FH in 15% of patients with premature CAD in North Indians. There are only 6 genetic studies in India of the total mutations, 32% are LDLR mutations, 4% are ApoB, 2% are PCSK9 mutations and the mutational spectrum for 37% is unknown. This calls for widespread genetic screening which could help identify definite FH patients.European Atherosclerosis Society-Familial Hypercholesterolemia Studies Collaboration (EAS- FHSC) has taken an initiative to develop a worldwide registry of FH. India is also a part of the collaboration and 3 groups from Mumbai, Delhi and Chennai are actively contributing to this registry. We believe this review might help to understand the Indian scenario of FH and investigators across India can contribute in managing FH in India and further help in the detection, diagnosis and treatment.     

Swedish neonatal nurses’ experiences of enhancing attachment to children born prematurely

The purpose of this study was to illuminate pediatric neonatal nurses' (PNNs') experiences of enhancing early attachment for the premature children in neonatal intensive care (NIC). An interview study with 8 PNNs in NIC in southeastern Sweden was conducted, and analyzed by content analysis. Result, illustrated three categories: Enabling closeness between the child and the parents, Supporting parents’ sense of parenthood, and Obstacles to enhancing attachment. Discussion, PNNs have a great role to supporting parents, but several barriers need to be addressed to make it easier for the PNN in NIC to enhance attachment for the child.
