目的对比七氟醚全程吸入麻醉与丙泊酚全程靶控输注麻醉在风湿性心脏病患者二尖瓣置换术中的应用效果。
方法选取2015年3月至2018年4月胶州市人民医院行风湿性心脏病患者116例,均行二尖瓣置换术,依照麻醉方式不同分为七氟醚组(58例)与丙泊酚组(58例)。丙泊酚组接受丙泊酚全程靶控输注麻醉,七氟醚组接受七氟醚全程吸入麻醉。观察对比两组意识消失时间、拔管时间及不同时点心肌酶[肌酸激酶同工酶(CK－MB)、心肌钙蛋白Ⅰ(cTnⅠ)]水平。
结果麻醉后七氟醚组意识消失及拔管时间短于丙泊酚组(P<0.05);T1～T3七氟醚组血清cTnⅠ水平低于丙泊酚组(P<0.05);T3七氟醚组血清CK－MB水平低于丙泊酚组(P<0.05)。
结论与丙泊酚全程靶控输注麻醉相比,七氟醚全程吸入麻醉应用于风湿性心脏病患者二尖瓣置换术中可有效缩短意识消失及拔管时间,减轻心肌损伤。 相似文献

Background
Intrahepatic cholangiocarcinoma (ICC) is the second most common malignancy arising from the liver. Fibulin-1 has been demonstrated to be involved in various cancers, however, its role in ICC remains unclear.Methods
To study the clinical value and potential molecular mechanism of Fibulin-1 in ICC, immunohistochemistry and bioinformatic analyses were performed using data in the Gene Expression Omnibus Datasets and The Cancer Genome Atlas database.Results
Fibulin-1 expression was overexpressed in ICC tissues compared with adjacent non-cancerous tissues, and was significantly associated with unfavorable overall survival. Moreover, similar genes were identified by Gene Expression Profiling Interactive Analysis and microarray data set. Next, functional and pathway enrichment analysis demonstrated that Fibulin-1 was overrepresented in the pathways of extracellular matrix organization and angiogenesis, which are associated with tumor progression and potential for metastasis. Gene set enrichment analysis indicated that the gene sets of epithelial mesenchymal transition, TGF-beta signaling pathway and angiogenesis were enriched in tissues with high Fibulin-1 level. Furthermore, Fibulin-1 silencing suppressed the ability of ICC tumor cells to form colonies and siFibulin-1 repressed the endogenous protein level of p-AKT.Conclusion
Collectively, this study suggests that Fibulin-1 overexpression may play key roles in the carcinogenesis and progression of ICC via regulation of tumor-related pathways. 相似文献997.
［摘要］ 神经生长因子（nerve growth factor,NGF）广泛分布于中枢神经系统及周围神经系统中,具有促进血管生长、创伤愈合和神经系统发育以及骨形成的作用。影响种植体骨结合稳定性的因素很多,种植体表面的性质是影响种植体骨结合的主要因素。NGF在种植体骨结合过程中具有增强骨细胞活性,促进成骨细胞分化、矿化,以及促进周围神经、血管形成的作用,它能够有效地促进种植体周围骨愈合,从而缩短口腔种植体骨愈合时间。本文就神经生长因子促进种植体骨结合的研究进展进行综述。 相似文献

Background
Patients with acute coronary syndrome show an inflammatory response that is known to affect platelet aggregation. We aimed to clarify the relationship between the inflammation severity and the effect of antiplatelet therapy after percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI).Methods
This retrospective, single-center study included 203 patients with STEMI who underwent primary PCI and were stratified on the basis of the antiplatelet therapy on admission (clopidogrel vs ticagrelor). Inflammation levels were defined as low, intermediate, and high, based on the tertiles of the distribution of high-specificity C-reactive protein levels pre-PCI. Platelet aggregation function during hospitalization and follow-up was quantified as residual adenosine diphosphate–induced platelet reactivity on light transmittance aggregometry. Inflammation markers were measured on admission and at 1 year post-PCI.Results
At intermediate and high levels of inflammation, residual adenosine diphosphate–induced platelet aggregation was significantly higher among clopidogrel users than among ticagrelor users. In the clopidogrel group, statistically significant differences in platelet aggregation function were observed among the 3 levels of inflammation. At 1 year post-PCI, ticagrelor users had significantly lower levels of interleukin-1β and higher levels of interleukin-35 and transforming growth factor-β.Conclusion
At different inflammation levels, ticagrelor provides more potent platelet inhibition than clopidogrel, suggesting that ticagrelor might exert a more stable antiplatelet effect at higher levels of systemic inflammation. Furthermore, ticagrelor is associated with reduced indices of inflammation on follow-up after PCI, suggesting that anti-inflammatory effects might play a role in the clinical benefit observed with antiplatelet therapy, which would provide an additional rationale for using ticagrelor in patients with STEMI undergoing primary PCI. 相似文献1000.

背景:目前临床上多采用自体或异体软骨移植、软骨膜或骨膜移植、软骨细胞移植等方法进行软骨损伤修复,但均因取材局限、免疫排斥等导致效果不佳。利用组织工程的方法再造软骨,为软骨缺损的临床修复提供了新的思路与途径。目的:利用SCI数据库文献检索和深度分析功能,对于组织工程软骨的文献资料趋势进行多层次探讨分析,根据检索文献结果分析组织工程软骨的发展趋势。方法:通过计算机检索SCI数据库中2001/2010有关组织工程软骨的文献,检索词为"软骨(cartilage);组织工程(tissueengineering);软骨细胞(chondrocyte/cartilage cell);软骨组织(cartilage tissue);支架材料(scaffold materials);种子细胞(seed cell)",以文字和图表的形式进行统计和结果分析,描述其分布特征。结果与结论:SCI数据库2001-01/2010-12收录组织工程软骨相关文献总计3137篇,中国在该领域的文献产出量逐渐增多,总体呈上升趋势,Biomaterials《生物材料》杂志发表文献量最多。美国在该领域文献产出量多于其他国家,对该领域研究起到重要作用,发表文献较多的机构集中在美国的哈佛大学,莱斯大学,麻省理工学院,哥伦比亚大学,加利福尼亚大学圣地亚哥分校等。 相似文献
