腭裂修复术腭咽肌肉重建与否的鼻咽内窥镜的比较观察

目的通过是否进行腭咽肌肉重建的两组腭裂修复术后患者鼻咽内窥镜的比较观察,了解腭咽部肌肉重建术后腭咽闭合状况的改变。方法将41例腭裂术后患者,按照在腭裂修复时是否进行腭咽肌肉重建分为重建组(22例)和非重建组(19例),以鼻咽纤维内窥镜记录静态和发音时腭咽闭合运动状况,对两组患者腭咽闭合运动类型和状况进行比较。结果重建组静态腭咽腔形态较非重建组明显缩小,各壁光滑丰满,未见软腭鼻腔面V型缺损畸形;动态时以环状闭合为主。非重建组静态腭咽腔形态较大,可见软腭鼻腔面V型缺损畸形;动态时以冠状闭合为主。经比较重建组腭咽闭合良好率(90.91%)明显优于非重建组(37.31%)。结论鼻咽内窥镜观察证实腭咽肌肉重建腭裂修复术后腭咽闭合功能恢复明显优于非重建组。腭裂修复术时重建腭咽肌肉有助于缩小腭咽腔和更易于达到良好的腭咽闭合状态。     

Paradigm shift in hydrocephalus research in legacy of Dandy’s pioneering work: rationale for third ventriculostomy in communicating hydrocephalus

Objective This study aims to question the generally accepted cerebrospinal fluid (CSF) bulk flow theory suggesting that the CSF is exclusively absorbed by the arachnoid villi and that the cause of hydrocephalus is a CSF absorption deficit. In addition, this study aims to briefly describe the new hydrodynamic concept of hydrocephalus and the rationale for endoscopic third ventriculostomy (ETV) in communicating hydrocephalus. Critique The bulk flow theory has proven incapable of explaining the pivotal mechanisms behind communicating hydrocephalus. Thus, the theory is unable to explain why the ventricles enlarge, why the CSF pressure remains normal and why some patients improve after ETV. Hydrodynamic concept of hydrocephalus Communicating hydrocephalus is caused by decreased intracranial compliance increasing the systolic pressure transmission into the brain parenchyma. The increased systolic pressure in the brain distends the brain towards the skull and simultaneously compresses the periventricular region of the brain against the ventricles. The final result is the predominant enlargement of the ventricles and narrowing of the subarachnoid space. The ETV reduces the increased systolic pressure in the brain simply by venting ventricular CSF through the stoma. The patent aqueduct in communicating hydrocephalus is too narrow to vent the CSF sufficiently.     

小型颅内动脉瘤的临床特点及血管内栓塞治疗

目的总结小型颅内动脉瘤的临床特点以及血管内栓塞的技术要点与疗效。方法对45例小型颅内动脉瘤患者采用电解可脱性弹簧圈(GDC)或Trufill DCS Orbit微型三维填塞型水解铂金弹簧圈进行动脉瘤囊内栓塞。结果45个动脉瘤中41个瘤腔100%闭塞,3个95%闭塞,1个90%闭塞。术后44例临床痊愈,其治疗结果根据Glasgow预后评分:Ⅰ级29例,Ⅱ级11例,Ⅲ级3例,Ⅳ级1例,Ⅴ级1例;全组死亡率2.2%。栓塞术中并发脑血管痉挛6例。术后随访3-69个月均无再出血及复发。结论对小型颅内动脉瘤采用GDC或Truffill DCS Orbit微型三维填塞型水解铂金弹簧圈进行血管内囊内栓塞疗效可靠;根据小型颅内动脉瘤的临床特点进行栓塞是提高治愈率、降低并发症及死亡率的重要方法。

《灵枢·官针》是关于中医古典针法的经典文献,其中所论刺痹法,内容丰富,手法多样,至今对临床仍有重要指导意义.刺痹法共有九种,毛刺法刺皮肤治浮痹,合谷刺刺肌肉治肌痹,恢刺与关刺刺筋腱治筋痹,输刺与短刺刺骨治疗骨痹.特殊操作类又有多针、多向刺法的齐刺、傍针刺和烧针刺法的焠刺,以治疗各种经久不愈的痹痛.研究这些古刺法,对于提高痹证的治疗效果,具有一定的指导意义.     

Clinical oncology—A new era

Rapid growth in biomedical research coupled with dramatic advancement in biotechnology has significantly improved our understanding of the molecular basis involving cancer development and progression. This improvement has led to the discovery of new molecular markers for cancer diagnosis and prognosis as well as new molecular targets for cancer treatment and intervention. Continuous emergence of some new developing area in molecular profiling, new therapeutic agents, tissue microenvironment and systems biology have made significant progress in clinical oncology. Clinical research and investigation that focus on these new developments have begun to show exciting results that indicate future promises in improving patient management and survival.     

免疫组化法检测非甲-非庚型肝炎患者肝组织中输血传播病毒

目的　检测非甲-非庚型肝炎患者肝组织输血传播病毒(TTV)感染状况,TTV感染与肝组织炎症程度 及与血液学指标的相关性。方法　应用免疫组织化学法检测52例非甲-非庚型肝炎患者肝组织中TTV,并经原位 杂交证实;对TTV阳性和阴性组的血液学生化指标,诸如血清丙氨酸转氨酶(ALT)、血清天冬氨酸转氨酶(AST)、血 清总胆红素(TBIL)、白蛋白(ALB)、γ 球蛋白(γ G)、凝血酶原活动度(PTA)及组织学活动指数(HAI)进行了比较。 结果　非甲-非庚型肝炎患者肝组织中TTV抗原(TTVAg)阳性15例,检出率为28.8%;阳性物质主要定位于肝细 胞浆内,呈棕黄色细小颗粒,偶见肝细胞核内有表达;TTV阳性表达细胞呈单个、散在或片簇状分布;TTVAg阳性的 组织切片经苏木素-伊红(HE)染色后,可观察到病毒性肝炎的一些病理变化,如肝细胞胞浆疏松化、气球样变、嗜酸 样变、灶性坏死、凋亡、小叶内及汇管区炎细胞浸润;从15例TTVAg阳性病例中任选10例进行TTV DNA原位杂交 检测,结果8例阳性,二者符合率80.0%;同时对5例免疫组化TTVAg阴性肝组织进行TTV DNA原位杂交检测,结 果5例均为阴性,二者符合率100%;TTVAg阳性组ALT、AST、TBIL、γ G均值均高于TTVAg阴性组,ALB、PTA 均值均低于TTVAg阴性组,但两组比较差异无统计学意义(P>0.0     

36例胰腺浆液性囊腺瘤的临床分析

目的：探讨胰腺浆液性囊腺瘤的诊断和治疗。方法：对1998年6月至2006年9月瑞金医院收治的36例病理诊断为胰腺浆液性囊腺瘤的临床资料进行回顾性分析。结果：胰腺浆液性囊腺瘤好发于中老年女性,多见于胰腺头颈部,无特征性临床表现。B超和CT诊断囊性肿瘤的正确率分别为69%（25/36）和94%（34/36）。CT对于囊腺瘤的诊断正确率为80%（29/36）,对浆液性囊腺瘤的诊断正确率为61%（22/36）。在不能排除或考虑实性假乳头状瘤的病人中MRI对于囊腺瘤的诊断正确率80%（4/5）。本组35例行手术治疗,其中7例行胰十二指肠切除;11例行胰腺节段切除;12例行胰体尾切除;5例行局部切除,1例行剖腹探查活组织检查。10例术后出现并发症,包括胰瘘、内出血、幽门梗阻、胰腺假性囊肿合并肠瘘病人及不同程度的胸腔积液。1例因内出血死亡。本组3例失访,32例获随访,除2例因其它疾病死亡,其余均健在,术后无复发。结论：CT和MRI,结合肿瘤学指标和临床病理特征可大大提高浆液性囊腺瘤的术前诊断率。浆液性囊腺瘤是一种良性的肿瘤,但手术治疗并发症较多。大多数浆液性囊腺瘤可考虑随访;有症状的胰腺浆液性囊腺瘤,或与黏液性囊性肿瘤不能鉴别者,应手术治疗。     

Surgery for ventricular tachycardia in patients undergoing surgical ventricular restoration: The Karolinska approach

This article presents a review on the efficacy of surgical ventricular restoration and direct surgery for ventricular tachycardia in patients with left ventricular aneurysm or dilated ischemic cardiomyopathy. The procedure includes a non-electrophysiologically guided subtotal endocardiectomy and cryoablation in addition to endoventricular patch plasty of the left ventricle. Coronary artery bypass surgery and mitral valve repair are performed concomitantly as needed. In our experience, this procedure yielded a 90% success rate in terms of freedom from spontaneous ventricular tachycardia, with an early mortality rate of 3.8%. A practical guide to the pre- and postoperative management of these patients is provided.
