Bloodletting Puncture at Hand Twelve Jing-Well Points Relieves Brain Edema after Severe Traumatic Brain Injury in Rats via Inhibiting MAPK Signaling Pathway

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.     

如何学好药理学

药理学是研究药物与机体相互作用、作用机制及规律的科学,是连接基础医学与临床医学、医学与药学的一门重要课程.许多学生在初次学习药理学时,认为药理学不好学,内容复杂、抽象,药物种类较多,抓不住重点,难以记忆,不知道怎样学习药理学,现就这些问题谈谈学习药理学的方法.     

昆虫抗冻蛋白及其在医学领域中的应用

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.     

Sternal Reconstruction of Deep Sternal Wound Infections Following Median Sternotomy by Single-stage Muscle Flaps Transposition

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.

中国器官移植的现状、成因及伦理研究

人体器官移植技术是指将他人的具有功能的心脏、肺脏、肝脏和肾脏等器官移植给患者以替代其病损器官的技术。中国器官移植始自20世纪60年代以来，移植数量逐步增加，发展速度逐渐加快，但与世界先进水平相比，除肾移植外其他器官移植从开展例数、存活时间或从效果上都存在较大差距，主要原因除技术、药物等条件方面外，还存在伦理发展与法规建设滞后的问题。因此，全面阐述器官移植的伦理问题，保障实现器官移植真正造福于民的目标，无疑具有十分重要的意义。

人类的历史教训证明,包括大地震在内的严重自然灾害,对地域生态环境和人类居住条件造成极大的破坏,对灾区人员的健康造成沉重的打击.在这种情况下,发生重大传染病流行的风险将会显著增加.汶川大地震发生后,搜寻生还者,抢救伤病员是抗震救灾第一阶段的重点.     

浅谈药理学课程改革

药理学是基础医学与临床医学之间的桥梁学科,对于临床治疗、预防、诊断都具有重要作用[1].由于该课程各章节间缺少联系,且药物种类繁多,同类药物的作用、用途、不良反应极易混淆,学生普遍觉得抽象、深奥、枯燥乏味.在教学中,灵活运用多种教学方法,可取得良好的教学效果.通过几年的药理学教学实践,笔者有如下建议.     

加强护理风险管理提高护理质量

风险管理是指对病人、工作人员、探视人员面临的潜在伤害的风险进行识别、评估,采取正确行动的过程[1].美国杜克大学将医疗风险定义为"遭受损失的可能性",这种损失可以是对病人的伤害以及由此付出的赔偿代价,也可以是投诉、纠纷等影响医院良好形象和市场分额[2].     

鼻衄患者的心理护理

随着现代医学模式的转变,心理护理对疾病的发展转归预后的作用日益受到重视,在耳鼻喉科病房做好心理护理则具有特殊的意义,尤其是鼻衄的患者能否针对心理因素进行恰当的处理,及时做好病人的心理护理,使病人情绪稳定、心理平衡、精神愉快,促成病人心理和生理之间的良性循环,直接影响到防治的效果,有助于病人治疗和康复,进一步发挥了药物不可及的独特作用.现将心理护理的体会介绍如下.
