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

目的:探讨痰瘀相关,意在梳理痰瘀知识、并强调痰瘀相关的重要性。方法:通过多角度地分析、刍议"痰瘀同源"、"痰瘀互结"、"痰瘀同治"等痰瘀经典理论的方式论述痰瘀相关。结果:痰与瘀是中医界里重要的元素,痰与瘀互结是许多疾患共同的病机,痰瘀同治是常用治法。结论:痰瘀同源、互结、同治,不但在临床上有着实用的指导意义,又能与时俱进、在探究中创新。 相似文献

载脂蛋白(apo)是脂蛋白的重要组成成分,其主要功能是调节酶活性,介导细胞受体与脂蛋白结合,保持脂蛋白结构的稳定性。目前已发现数十种载脂蛋白,其结构的显著特点是分子中具有多个双性alpha螺旋及Beta-折叠结构。载脂蛋白的这种双性alpha螺旋结构是其结合及转运脂质的结构基础。在HIV外壳结构中的一种糖蛋白(gP)也具有这种alpha螺旋结构。近年研究表明,载脂蛋白和由载脂蛋白组成的脂质体还具有抗肝炎病毒、抗HIV病毒、抗单纯疱疹和中和细菌内毒素的功能。以脂蛋白和载脂蛋白为主要成分构成的脂质体已成为运载抗病毒和抗肿瘤药物受体的靶向性载体。 相似文献

解剖学与中医理论的隔阂与融合(上) 总被引:1,自引:0,他引:1
分析了解剖学与中医理论发展的历史关系。指出古代的解剖在构建了中医基础理论之后逐步走向式微,中医理论与解剖学之间的隔阂在近代达到顶峰。这种隔阂是一种历史性的结果,随着历史条件的改变,中医理论可以实现与解剖学的融合,从解剖脏器非对称特征中蕴含的阴阳规律具体论证了这一问题。在现代条件下,对解剖的反思和排斥已不具有积极意义,建立中医理论的形态学基础是中医理论发展的必然。 相似文献

4 解剖脏器非对称特征中的阴阳规律显示出中医理论在新的历史条件下可以实现与解剖的融合
中医学认识解剖结构问题,当然要从自己的基本理论出发,最重要的首先是阴阳,同时要以确切的现代解剖内容为客观研究对象。就阴阳和解剖的关系这一具体问题而言,内脏基本结构的非对称性符合阴阳规律,中医理论在新的历史条件下可以实现与解剖的融合,从而为未来进一步的发展奠定新的基础。 相似文献
