免疫调理在呼吸机相关性肺炎防治中的应用

呼吸机相关性肺炎(ventilator associated pneumonia,VAP)是机械通气患者常见的并发症之一,也是引起重症监护室（ICU）住院患者感染的常见原因。目前临床上VAP的发生率及病死率仍居高不下,探寻更为有效的防治措施任重道远。众多研究表明,免疫调理在治     

髓心减压人工骨植入治疗早期股骨头坏死的护理

目的探讨个性化护理对早期股骨头坏死行髓芯减压患者的应用。方法选择在我院治疗的50例股骨头坏死患者,均行髓心减压人工骨植入术,所有患者随机分为实验组和对照组,实验组给予常规护理结合个性化护理,而对照组给予常规护理,术后3个月观察两组患者的Harris髋关节评分。结果实验组经个性,化护理后Harris髋关节评分总体分布较对照组好（χ^2=4．20,P〈0．05）。结论经个性化护理后髓芯减压患者的Harris髋关节评分较高,利于患者术后康复。     

氧化苦参碱对大鼠急性心肌梗死诱发室性心律失常的影响

目的探讨氧化苦参碱（OMT）对急性心肌梗死（MI）大鼠诱发室性心律失常（VA）的影响及其可能机制。 方法健康雄性SD大鼠75只,使用数字表法随机分为假手术组（Sham组）、MI组和OMT干预组（OMT组）,每组25只。MI组和OMT组通过结扎冠状动脉左前降支建立MI模型,假手术组开胸但不结扎冠状动脉。OMT组在模型建立前2周及模型建立后2周连续给予OMT（100 mg/kg）灌胃处理。模型建立后2周,行心脏超声检查评估左心功能,酶联免疫吸附法检测血浆N-末端脑钠肽前体（NT-proBNP）和超敏肌钙蛋白T（hs-TnT）水平,分别使用RT-PCR和Western blotting检测心肌缝隙连接蛋白43（Cx43）mRNA和蛋白的表达,采用Burst刺激诱发VA。 结果OMT组NT-proBNP、hs-TnT水平［（256.45±38.55）、（89.55±13.39）ng/L］与MI组［（371.93±41.23）、（132.63±20.12）ng/L］比较明显降低（P＜0.01）。Sham组、MI组与OMT组Cx43 mRNA相对表达量依次为0.93±0.16、0.47±0.06和0.71±0.12,3组Cx43蛋白相对表达量依次为0.77±0.11、0.50±0.07和0.61±0.08,3组p-Cx43蛋白相对表达量依次为0.62±0.09、0.32±0.05和0.50±0.07,差异均有统计学意义（P均＜0.05）。此外,OMT组与MI组比较VA诱发率明显降低（21.4% vs 64.3%,P＜0.05）。 结论OMT可降低MI大鼠心肌的损伤和VA的发生率,其机制可能与OMT调整MI后心肌的Cx43表达有关。     

Assessment of biocompatibility and initial evaluation of genipin cross-linked elastin-like polypeptides in the treatment of an osteochondral knee defect in rabbits

Polypeptides based on the alternating hydrophobic and cross-linking domain structure of human elastin are capable of undergoing self-assembly to produce polymeric matrices with unique biological and mechanical properties. Here, we test the initial feasibility of using a genipin cross-linked elastin-based material as an acellular plug in the treatment of an osteochondral defect in the rabbit knee. Full-thickness defects in the weight-bearing surface of the medial femoral condyle in 18 New Zealand White rabbits were surgically produced and press fitted with cylindrical pads composed of genipin cross-linked elastin-like polypeptides, with identical wounds in the opposite knee left untreated as controls. The biocompatibility of the material, overall wound healing and regeneration of subchondral tissue was assessed at 2, 4 and 6 weeks by histological evaluation, synovial fluid analysis and microcomputerized tomography scanning. Histological analysis revealed the regeneration of subchondral bone at the periphery of the material, with evidence of hyaline-like overgrowth across the apical surface in 11/16 cases. Pads developed tight contacts with host tissue and appeared completely biocompatible, with no evidence of localized immune response or increased inflammation compared to controls. The material was stable to 6 weeks, with an aggregate elastic modulus calculated at ～470 kPa when tested under confined compression. Further studies are required to assess material degradation over time and long-term replacement with repair tissue.     

自发性冠状动脉夹层并血栓形成致急性心肌梗死2例

急性心肌梗死(AMI)是心内科的常见急症,其病死率和致残率较高。自发性冠状动脉夹层(SCAD)可因假腔压迫及合并血栓形成导致冠状动脉闭塞,是AMI的罕见病因之一。本文报告2例SCAD并血栓形成致AMI,并行冠状
