三维重建单(双)靶点定向置管引流术治疗高血压壳核出血

目的回顾性分析三维重建单(双)靶点定向置管引流术治疗高血压壳核出血的疗效,验证该方法的有效性和可行性。方法将133例壳核脑出血病人的CT定位扫描资料输入计算机工作站,对血肿进行三维重建,根据血肿量的大小和形状设计1～2个靶点和引流管路径。应用立体定向技术将引流管(外径5mm,内径3mm)送至颅内预定靶点,术中应用10ml注射器轻柔抽吸血肿液化部分,术后将尿激酶(1～2万IU)注入血肿腔内,夹闭引流管2h后自然引流,每12h重复1次。复查CT证实剩余血肿量为最初的10%~15%时拔除引流管。结果平均置管1.5 d(1～3d),平均血肿排空率92.8%。术后1个月病死率6.0%,远期随访(平均22个月)病死率11.3%,优良率74.4%。结论该方法治疗高血压壳核脑出血,血肿排空较彻底,疗效可靠,尤其适用于血肿量较大(>25ml)且形态不规则的颅内血肿。

Long-Term Outcome of Adult-to-Adult Living Donor Liver Transplantation for Post-Kasai Biliary Atresia

Our objective was to analyze problems in the perioperative management and long-term outcome of living donor liver transplantation (LDLT) for biliary atresia (BA). Many reports have described the effectiveness of liver transplantation (LT) for BA, particularly in pediatric cases, but little information is available regarding LT in adults (> or =16 years old). Between June 1990 and December 2004, 464 patients with BA underwent LDLT at Kyoto University Hospital, of whom 47 (10.1%) were older than 16 years. In this study, we compared the outcomes between adult (> or =16 years old) and pediatric (<16 years old) patients. The incidence of post-transplant intestinal perforation, intra-abdominal bleeding necessitating repeat laparotomy and biliary leakage was significantly higher (p < 0.0001, <0.001 and <0.001, respectively) in adults. Overall cumulative 1-, 5- and 10-year survival rates in pediatric patients were significantly higher (p < 0.005) than in adults. Two independent prognostic determinants of survival were identified: a MELD score over 20 and post-transplant complications requiring repeat laparotomy. Outcome of LDLT in adult BA patients was poorer than in pediatric patients. It seems likely that LT will be the radical treatment of choice for BA and that LDLT should be considered proactively at the earliest possible stage.     

树型金银花无公害优质加工技术的研究

目的探讨树型金银花无公害优质加工技术。方法采用树型金银花晾晒和烘烤以及"烤房3段变温烘烤技术"。结果烘干产品比晒干产品具有明显的质量和价格优势,价格高57.1%。烤房3段变温技术第1段烘干温度控制在35～40℃,烘8～9h;第2段将温度提高到50～55℃左右,烘烤6～8h;第3段温度升到60～70℃,烘烤5～6h左右;烘干总时间不超过24h。结论无公害优质加工技术利于规模化生产,获得无公害的绿色产品,增加金银花附加值。     

腰椎间盘突出症CT诊断与三维瞬间牵引

目的 :探讨腰椎间盘突出症的 CT表观及三维瞬间牵引的治疗效果。材料与方法 :回顾分析经 CT及临床诊断为腰椎间盘突出症病例 16 7例的临床及 CT资料。结果 :16 7例腰椎间盘突出症表现为单个或多个椎间盘的突出 ,硬脊膜囊、硬膜外间隙及神经根受压等征象。经三维瞬间牵引后 6 5例 (38.9% )症状有不同程度缓解 ,其中 94例 (5 6 .3% )症状完全消失。结论 :CT是腰椎间盘突出症的有效诊断手段之一     

Scales of depression,ill-being and the quality of life—is there any difference? An assay in taxonomy

The application of a model based on the three time dimensions of past, present and future can be used to generate an alternative taxonomy for the classification of depression, ill-being and quality of life. In relation to time, depression can be defined as the passage from a healthy past to a painful present, ill-being as the painful present of the individual and the quality of life (QOL) as the degree to which the subject's present life is commensurate with his aspirations. Such an approach opens up conceptual and methodological areas of research which will allow the construction of a new type of scale. Depression scales should be constructed with two time dimensions: past and present; ill-being scales only refer to the present and QOL scales should have two time dimensions: present and future. It would be possible to combine these three scales into a single scale with three dimensions. Such a scale would enable depression and ill-being to be quantified, accurately diagnosed and monitored. The relative importance of principal symptoms could be assessed, facilitating the choice of therapy and follow-up methods.     

齿状突骨折的 CT三维重建分型及临床意义

目的探讨齿状突骨折的CT三维重建分型及临床意义。方法2000年9月～2004年6月,对32例寰枢椎损伤患者均行X线检查、螺旋CT薄层扫描及三维重建检查,评价CT三维重建分型及临床意义。结果X线片检查对齿状突骨折的漏诊率为28.13%(9/32),CT平扫漏诊率为6.25%(2/32),CT三维重建无1例漏诊。结论X线片对齿状突骨折易造成漏诊或诊断不确切。CT三维重建能直观、精确地显示病变的立体形态及各解剖结构的空间关系,提供分型依据,对治疗具有指导作用。     

腹腔镜辅助胆道造影在幼婴延迟性黄疸诊断中的价值

目的探讨腹腔镜辅助胆道造影在幼婴延迟性黄疸诊断中的价值。方法首先脐部置镜观察胆囊及肝脏情况,如果胆囊大小正常或基本正常,通过右肋缘下trocar孔拖出胆囊底部,部分患儿需游离胆囊系膜。切开胆囊,插管行胆道造影。如果胆囊呈纤维闭锁状态,不能拖出腹腔外,中转开腹。切开胆囊插管失败,放弃造影。结果12例患儿直接从拖出胆囊行胆道造影显示婴儿肝炎综合征或胆汁淤积8例;2例显示为胆管发育不良;2例为肝内胆管闭锁。5例从肝脏游离胆囊系膜后拖出造影,2例显示为胆管发育不良,3例提示胆道闭锁。其余21例患儿胆囊呈条索状,不同程度肝硬化,放弃胆道造影,诊断为胆道闭锁。所有胆道闭锁患儿均行Kasai手术。结论腹腔镜探查、胆道造影是诊断胆道闭锁、鉴别幼婴延迟性黄疸简便、准确、安全的方法,能够显示整个胆树的解剖结构,避免过大或不必要的创伤。
