新生儿糖代谢紊乱的临床分析

糖代谢紊乱在新生儿期不少见，由于常被原发或继发疾病所掩盖，如未能及时发现及妥善处理均可能加重致影响新生儿脑正常发育和脑功能损害。我们通过对高危儿血糖测定，监测血糖水平变化，早期发现并及时纠正糖紊乱，对其预后有重要影响。现对2000年3月-2005年11月入住我科的血糖异常患儿进行分析。     

抗醛糖还原酶单克隆抗体的制备与特性鉴定

目的:制备抗醛糖还原酶(AR)的单克隆抗体(mAb),并与本室制备的抗醛糖还原酶相似蛋白(ARL-1)mAb进行比较。方法:经RT-PCR获得AR基因,将基因插入pGEX-4T-1(His)6C中,构建重组质粒pGEX-4T-1(His)6C-AR,以重组质粒转化E.coliRosetta诱导表达GST-AR蛋白。以纯化的GST-AR蛋白免疫BALB/c小鼠,采用杂交瘤技术制备mAb。应用间接ELISA和Western blot方法对mAb进行筛选和鉴定。使用Clustalx和Antheprot软件,比较AR与ARL-1的同源性,表达GST-dAR[80~142氨基酸(aa)],与ARL-1差异较大;并分析AR的抗原性,表达GST-dA1(1~79aa)、GST-dA2(80~99aa)、GST-dA3(111~142aa)、GST-dA4(143~316aa)。利用AR全长及截短蛋白,采用Western blot分析制备的抗AR mAb识别AR抗原的部位。结果:获得3株稳定分泌抗AR mAb的杂交瘤细胞系ARB3、AR7B3G4和ARF10。3株抗GST-AR的mAb均为IgG1(κ型),腹水mAb效价为1∶4×105,细胞培养上清mAb效价为1∶1×104,3株mAb均可与胎盘组织中的AR蛋白起反应,而与GST-ARL-1和GST蛋白无交叉反应。它们分别为抗GST-dA1、GST-dA3和GST-dA4蛋白的mAb。结论:成功地制备了3株特异性抗AR mAb,可分别识别AR的1~79、111~142、143~316位氨基酸。将它们与抗ARL-1mAb联合应用,将有助于进一步研究AR与ARL-1蛋白的功能,并为深入探讨AR、ARL-1与相关疾病的关系及进行大规模的流行病学调查提供了有力的工具。     

空腹血糖受损下限诊断切割点的建议

糖尿病是一组由于血糖水平过高而引起组织、器官功能及结构异常的疾病。糖调节受损（impaired glucose regulation，IGR）是任何一种类型糖尿病发病过程中的中间阶段。根据空腹和负荷后血糖值，IGR可分为两种高血糖状态——空腹血糖受损（impaired fasting glucose，IFG）和糖耐量受损（impaired glucose tolerance，IGT）。     

几丁糖预防术后腹腔粘连的实验研究

目的探讨几丁糖对术后腹腔粘连的预防作用.方法将45只大鼠随机分为A、B、C 3组,于腹腔内浆膜损伤部位分别注入1%乳酸液、32%右旋糖酐-70液和2%几丁糖乳酸液各2 ml,术后14 d处死动物,观察各组腹腔粘连状况.结果 3组粘连分级比较有显著性差异(P＜0.01),C组粘连发生率与另2组有显著差异(P＜0.05).光镜下C组炎症反应轻微,纤维增生不明显;电镜下C组纤维细胞分泌胶原能力弱,间皮细胞增生活跃.结论几丁糖可有效降低大鼠术后腹腔粘连的发生和粘连程度,其作用优于右旋糖酐-70,且不影响切口的愈合.     

高渗氯化钠羟乙基淀粉40注射液高容量血液稀释对大鼠肝脏缺血再灌注损伤的影响

Objective To investigate the effects of hypervolemic hemodilution (HH) with hypertonic saline plus hetastarch solution 40 injectio on hepatic ischemia-reperfusion (I/R) injury in rats. Methods Thirty male Wistar rats weighing 300-350 g were randomly divided into 3 groups ( n = 10 each): group I sham operation (group S); group II I/R and group Ⅲ HH. Partial liver ischemia was produced by clamping hepatic portal vein and left arteria hepatica for 30 min with atraumatic mini-clamp, followed by 2 h of reperfusion in I/R group and HH group. In HH group the animals were infused hypertonic saline plus hetastarch solution 40 injectio 10 ml/kg through vena caudalis over 30 min and then hepatic I/R was performed IS min after the infusion.The animals were killed at 2 h of reperfusion. The left liver was removed and blood sample was taken from inferior caval vein for determination of (1) serum alanine amino transferase (ALT) and aspartate amino transferase (AST) activities; (2) superoxide dismutase ( SOD) activity and malondialdehyde ( MDA) content in the liver; ( 3 ) microscopic examination. Results The serum ALT and AST activities and MDA content in the liver were significantly higher, SOD activity in the liver significantly lower after hepatic I/R and pathological changes in the liver severer in group I/R and HH than in group S. The serum ALT and AST activities and MDA content in the liver were significantly lower, SOD activity in the liver significantly higher after hepatic I/R and pathological changes in the liver milder in group HH than in group I/R. Conclusion Hypervolemic hemodilution with hypertonic saline plus hetastarch solution 40 injectio can ameliorate hepatic I/R injury by decreasing oxygen free radical production in rats.
