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

长期以来,教务处汇总处理学生学期考试成绩的工作相当繁重。在没有计算机的年代,每学期末,各学科成绩上报到教务处后,所有成绩的处理都是手工操作。近年来,计算机也只是代替了很少部分的人力,成绩的录入、校对、计算、统计汇总,以及各班班主任对学生成绩进行评定等,基本上还是手工操作,花费了大量的时间和精力,出错的几率还非常高,工作效率很低,严重影响了此项工作的顺利完成。 相似文献

A case of bilateral phaeochromocytoma with catecholamine-induced myocarditis is described. The two operations needed allowed comparison of the use of alpha-methyl-p-tyrosine alone and in conjunction with adrenergic blocks in the management of the patient. The combination of both drugs was particularly successful in the relief of symptoms and reduction of catecholamine metabolism as monitored by 4-hydroxy-3-methoxymandelic acid (HMMA) excretion. As myocarditis is a potentially fatal complication, further investigation of the combined use of alpha-methyl-p-tyrosine and adrenergic blocking drugs is suggested in the pre-operative management of patients with phaeochromocytoma. 相似文献
