危重患者血浆中性粒细胞明胶蛋白酶相关载脂蛋白浓度的测定及其临床意义

Objective To detect the concentration of plasma neutrophil gelatinase-associated lipocalin (NGAL) and the clinical significance in critically ill patients. Methods Fifty-four critically ill patients in ICU were enrolled in the present study with 23 health persons as controls. Plasma NGAL concentration was measured by enzyme-linked immunosorbent assay (ELISA) on the 1 st and 7th day from 54 adult patients in ICU and the controls (control group). Results The plasma NGAL concentrations of ICU patients were significantly higher than those of the controls (P ＜0.001 ). NGAL concentrations were no significant difference between the Death group and the Survival group on the 1 st day(P = 0. 259). But there was a markedly significant difference in Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ scores (P ＜0. 001 ). The APACHE Ⅱ scores on the 7th day significantly decreased in the improved patients (P =0.019) and showed a subtle tendency of increase in the deteriorated patients ( P =0.403) in comparison to the first day. The plasma NGAL levels followed the same trends, but showing a significant increase even in deteriorated patients ( P = 0. 016 and P= 0. 034, respectively). Conclusions The plasma NGAL concentrations of critically ill patients is significantly increased. Combined with APACHE Ⅱ scores,it can provide useful and available data of the disease state of critically ill patients.     

强化血浆置换联合肾上腺皮质激素治疗急进性肾小球肾炎的疗效

[目的]探讨强化血浆置换联合肾上腺皮质激素治疗急进性肾小球肾炎(RPGN)的临床疗效.[方法]采用强化血浆置换联合肾上腺皮质激素治疗59例RPGN患者,对患者的治疗效果进行分析.[结果]患者平均进行强化血浆置换(13.2±2.6)次,平均住院时间(72.8±11.0)d,血尿消失时间(27.4±11.6)d,浮肿消退时间(15.8±5.1)d,血压恢复时间(14.7±4.2)d.治疗4周后、治疗8周后患者血清白蛋白(ALB)、肾小球滤过率(eGFR)、24 h尿量均较治疗前显著提高,且差异具有显著性(P<0.05),尿蛋白、血肌酐(SCr)、抗肾小球底膜抗体测定值较治疗前均显著降低(P<0.05).59例患者中痊愈为25.42%(15/59),好转为57.63%(34/59),无效占16.95%(10/59),治疗至出院时评估为无效的10例患者均在本院门诊血液透析中心进行血液透析治疗.[结论]强化血浆置换联合肾上腺皮质激素治疗RPGN具有较好的疗效,临床上应该尽早对患者进行血浆置换治疗.     

重症胰腺炎内科保守治疗的护理

CTP与DWI检查在急性脑梗死缺血半暗带中的应用价值

[目的]探讨全脑CT灌注成像(CTP)与弥散加权成像(DWI)检查在急性脑梗死(ACI)患者缺血半暗带(Ischemic penumbra,IP)中的应用价值.[方法]回顾性分析2019年2月至2020年7月在本院诊治的154例ACI患者,所有患者均进行CTP、DWI检查,对比不同区域的CTP脑灌注参数值、DWI参数值...     

急性主动脉夹层2例分析

急性主动脉夹层（AD）是血液渗入主动脉中层形成夹层血肿并沿主动脉壁延伸解离的严重心血管疾病,常造成猝死。由于该病临床症状、体征缺乏特异性,极易漏诊和误诊。现就我院收治的2例分析如下。     

蒜素对大鼠急性脊髓损伤的保护作用研究

[目的]研究蒜素对大鼠急性脊髓损伤的保护作用.[方法]采用改良的Allen's法制备大鼠急性脊髓损伤模型,18只健康雌性SD大鼠随机分为假手术组(sham)、急性脊髓损伤组(ASCI)和急性脊髓损伤+蒜素组(ASCI+allicin).给药组于手术开始前1 h腹腔注射蒜素,术后每日1次,持续2周.术后1 d、4 d、7 d、14 d、21 d分别对各组大鼠进行BBB评分,评估用药后蒜素对大鼠运动功能的影响;术后21 d处死大鼠取材,HE染色观察各组大鼠脊髓组织的形态学变化,Real-time PCR检测脊髓组织中炎性因子白介素6(IL-6)和白介素10(IL-10)mRNA的表达.[结果]蒜素治疗21 d,同ASCI组比较,大鼠的BBB评分显著升高(P<0.01),炎性细胞浸润程度明显减轻,促炎因子IL-6的表达显著降低(P<0.01),抗炎因子IL-10的表达显著升高(P<0.01).[结论]蒜素对大鼠急性脊髓损伤具有明显保护作用,其机制可能与抗炎作用有关.     

心电图3级心肌缺血对急性心肌梗死患者直接PCI后ST段回落的预测价值

[目的]评估心电图3级缺血(G3I)对急性ST段抬高型心肌梗死(STEMI)患者直接PCI (pPCI)术后ST段回落(STR)的临床价值.[方法]选择282例STEMI患者,依据术后STR程度将其分为STR组(n=234)和non-STR组(n=48),随访12个月,记录院内和出院后的主要不良心血管事件.[结果](82.9％)pPCI术后ST段回落良好,回落不良者为48(17.1％).non-STR组血清氨基末端B型脑钠肽前体(NT-proBNP)、肌钙蛋白Ⅰ(cTnⅠ)、肌酸激酶同工酶(CK-MB)峰值水平及G3I发生率均显著高于STR组,LVEF低于STR组,两组间Kil-lip分级差异显著,差异均具有统计学意义(均P＜0.05).logistic回归分析显示,G3I是pPCI术后non-STR的独立预测因子(P =0.018).non-STR组患者pPCI术后的平均住院日长(P=0.011),总的主要不良心脏事件发生率高(P =0.026).[结论]G3I可预测STEMI患者pPCI后non-STR,non-STR患者临床预后差.
