目的 在接受急诊冠脉介入术(PCI)的急性ST段抬高型心肌梗死患者中,评价术前使用安心颗粒联合血栓抽吸术对心肌灌注的影响。方法 160例接受急诊冠脉介入术的急性ST段抬高型心肌梗死患者被随机分为安心颗粒组(术前顿服安心颗粒8.8 g,术后安心颗粒4.4 g/次,每日2次)和对照组。所有患者均服用阿司匹林、氯吡格雷和阿托伐他汀。术后观察心肌呈色分级(MBG)、心电图ST段回落百分比、肌钙蛋白(cTnI)和肌酸激酶同工酶(CK-MB)峰值、左室射血分数(LVEF)、主要不良心脏事件(MACE)。结果 安心颗粒组术后的MBG分级较高(P<0.05),达到MBG 3级的患者比例较多(P<0.05),术后ST段回落百分比>70%的患者数较对照组多(P<0.05),cTnI(P<0.01)和CKMB(P<0.05)峰值时间提前。术后第30天,安心颗粒组患者的左室射血分数明显高于对照组(P<0.01)。第(30±1)天时,2组患者主要不良心脏事件发生人数无显著性差别(P>0.05)。结论 急诊冠脉介入术前使用安心颗粒,联合血栓抽吸术,能改善心肌灌注和泵功能,但对短期内主要不良心脏事件无影响。 相似文献

Objective:To investigate whether blood-brain barrier(BBB)served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points(HTWP)in traumatic brain injury(TBI)and the potential molecular signaling pathways.Methods:Adult male Sprague-Dawley rats were assigned to the shamoperated(sham),TBI,and bloodletting puncture(bloodletting)groups(n=24 per group)using a randomized number table.The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days.The neurological function and cerebral edema were evaluated by modified neurological severity score(mNSS),cerebral water content,magnetic resonance imaging and hematoxylin and eosin staining.Cerebral blood flow was measured by laser speckles.The protein levels of aquaporin 4(AQP4),matrix metalloproteinases 9(MMP9)and mitogen-activated protein kinase pathway(MAPK)signaling were detected by immunofluorescence staining and Western blot.Results:Compared with TBI group,bloodletting puncture improved neurological function at 24 and 48 h,alleviated cerebral edema at 48 h,and reduced the permeability of BBB induced by TBI(all P<0.05).The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture(P<0.05 or P<0.01).In addition,the extracellular signal-regulated kinase(ERK)and p38 signaling pathways were inhibited by bloodletting puncture(P<0.05).Conclusions:Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways.Therefore,bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema. 相似文献

抗冻蛋白(antifreeze protein,AFP)是一类结构多样的蛋白质,具有热滞效应(thermal hysteresis,TH,降低冰点而不改变熔点)和重结晶抑制效应(recrystalization inhabition,RI).通过非共价吸附抑制机制吸附到冰核表面,限制冰晶生长和抑制冰晶重结晶,从而保护有机体免受结冰引起的伤害.由于抗冻蛋白具有阻止冰晶生长而不破坏细胞的特点,因而利用抗冻蛋白在低温中长期保存各种细胞、组织和器官,特别在器官移植中可能具有很好的应用前景. 相似文献

Objective To assess clinical effectiveness of using bilateral pectoralis major or plus rectus abdominis muscle flaps in treating deep sternal wound infection (DSWI) following median sternotomy. Methods Between January 2009 and December 2013, 19 patients with DSWI after median sternotomy for cardiac surgery were admitted to our hospital, including 14 males (73.7%) and 5 females (26.3%), aged 55±13 (18-78) years. According to the Pairolero classification of infected median sternotomies, 3 (15.8%) patients were type II, and the other 16 (84.2%) were type III. Surgical procedure consisted of adequate debridement of infected sternum, costal cartilage, granulation, steel wires, suture residues and other foreign substances. Sternal reconstruction used the bilateral pectoralis major or plus rectus abdominis muscle flaps to obliterate dead space. The drainage tubes were placed and connected to a negative pressure generator for adequate drainage. Results There were no intraoperative deaths. In 15 patients (78.9%), bilateral pectoral muscle flaps were mobilized sufficiently to cover and stabilize the defect created by wound debridement. 4 patients (21.0%) needed bilateral pectoral muscle flaps plus rectus abdominis muscle flaps because their pectoralis major muscle flaps could not reach the lowest portion of the wound. 2 patients (10.5%) presented with subcutaneous infection, and 3 patients (15.8%) had hematoma. They recovered following local debridement and medication. 17 patients (89.5%) were examined at follow-up 12 months later, all healed and having stable sternum. No patients showed infection recurrence during the follow-up period over 12 months. Conclusion DSWI following median sternotomy may be effectively managed with adequate debridement of infected tissues and reconstruction with bilateral pectoralis major muscle or plus rectus abdominis muscle flap transposition. 相似文献
