骨肉瘤增殖细胞核抗原（PCNA）表达及其与临床病理和预后的关系

应用单克隆抗体ＰＣ１０免疫组方法半定量分析了增殖细胞核抗原表达与５０例骨肉瘤患者预后的关系。ＰＣＮＡ阳性级者预后差，其中半定量分级与骨肉瘤术后生存期呈显著负相关。ＰＣＮＡ表达与骨肉瘤组织学分级及骨样组织分化程度相关。     

鼻内窥镜诊治脑脊液漏的临床研究

目的 探讨鼻内窥镜手术治疗脑脊液鼻漏临床相关因素。方法 对17例（19漏）内窥镜下修补脑脊液鼻漏患者的临床资料作回顾性分析。结果 脑脊液鼻漏17例中，外伤性15例，自发性2例，内窥镜下瘘口修补术一次性治愈15例，成功率88.2%，失败2例，再次修补成功，其中1例颅内高压术后腰穿持续引流减压。结论 内窥镜手术修补脑脊液鼻漏准确、微创；冠位CT薄层扫描对术前瘘口解剖定位有重要意义；影响手术效果的因素与修补材料的固定有关，与修补材料本身无明显关系；术后适当腰穿引流对于临床提示颅内压高、修补区薄弱病例仍需采用。

Tacrolimus with Mycophenolate Mofetil (MMF) or Sirolimus vs. Cyclosporine with MMF in Cardiac Transplant Patients: 1-Year Report

The most advantageous combination of immunosuppressive agents for cardiac transplant recipients has not yet been established. Between November 2001 and June 2003, 343 de novo cardiac transplant recipients were randomized to receive steroids and either tacrolimus (TAC) + sirolimus (SRL), TAC + mycophenolate mofetil (MMF) or cyclosporine (CYA) + MMF. Antilymphocyte induction therapy was allowed for up to 5 days. The primary endpoint of >/=3A rejection or hemodynamic compromise rejection requiring treatment showed no significant difference at 6 months (TAC/MMF 22.4%, TAC/SRL 24.3%, CYA/MMF 31.6%, p = 0.271) and 1 year (p = 0.056), but it was significantly lower in the TAC/MMF group when compared only to the CYA/MMF group at 1 year (23.4% vs. 36.8%; p = 0.029). Differences in the incidence of any treated rejection were significant (TAC/SRL = 35%, TAC/MMF = 42%, CYA/MMF = 59%; p < 0.001), as were median levels of serum creatinine (TAC/SRL = 1.5 mg/dL, TAC/MMF = 1.3 mg/dL, CYA/MMF = 1.5 mg/dL; p = 0.032) and triglycerides (TAC/SRL = 162 mg/dL, TAC/MMF = 126 mg/dL, CYA/MMF = 154 mg/dL; p = 0.028). The TAC/SRL group encountered fewer viral infections but more fungal infections and impaired wound healing. These secondary endpoints suggest that the TAC/MMF combination appears to offer more advantages than TAC/SRL or CYA/MMF in cardiac transplant patients, including fewer >/=3A rejections or hemodynamic compromise rejections and an improved side-effect profile.     

Preexpanded distant "super-thin" intercostal perforator flaps for facial reconstruction without the need for microsurgery.

BACKGROUND: Concept of the 'super-thin perforator flap' was introduced in 1994 by authors. Since then, various types of 'super-thin perforator flaps' were applied successfully especially for contour sensitive reconstruction such as face and neck. METHODS: Eleven patients requiring large flaps who presented with extensive disfiguring facial scar (male: seven cases, female: four cases). On the consideration of flaps' colour, texture and thickness requirements, the authors selected 'super-thin' anterior intercostal perforator flaps (AICP, range from 4 x 14 cm to 25 cm x 9 cm) for reconstruction purpose. First, tissue expanders (volume range from 800 cc to 1200 cc) were carefully inserted under the AICP. After the flaps were expanded for 2 months, distant scars were removed and the covering super-thinned flaps were transferred into recipient site. Two weeks later, pedicles in the anterior chest were cut down and flaps were transferred to replace all the left scars. RESULTS: Flap were survived without any complications. The colour, texture and thickness of the transferred flap were satisfactory, shrink of flaps were not observed after long term follow-up. The authors present a method of facial reconstruction that has the advantages of creating a large amount of thin tissue of both good colour and texture, without the need of microsurgery and few disadvantages of donor-site morbidity. The disadvantages are three-staged procedures, complications of tissue expansion and uncomfortable compulsory posture for patients. In our opinion, this is an alternative method of choice for reconstructing all large defects in the lower two-thirds of the face.

在音乐缭绕中痊愈

你是否曾经因为它血脉贲张浑身发抖过．你是否因为它心潮起伏热泪盈眶过？如果这世界上没有它．你怕么？当天堂的圣歌响起．即使面对死亡．你也无所畏惧，它以它温柔的手．抚平你心里和肉体的伤……它让你不痛。[编者按]     

颅脑损伤所致人格改变的量化评估

目的:通过对颅脑损伤所致器质性人格改变的患者进行量化评估分析,以寻找一种最适合颅脑损伤后人格改变的量化评估方法。方法:全部病例来自2003-01-03/2005-01-31期间到深圳市康宁医院法医精神病司法鉴定所进行工伤鉴定的工伤所致颅脑损伤患者116例,所有病例首先由综合医院神经外科行头颅CT或MRI检查,并对颅脑损伤的部位、性质、严重程度等做出诊断和治疗。治疗终结后,由两名副高级主任医师及以上职称的精神医学鉴定专家对患者的精神状况进行评估,并分别做出有无人格改变的诊断。同时采用慢性脑器质性人格改变评定量表(包括10个条目)及自编脑外伤后人格改变评定量表(包括5个因子17个条目)对患者人格改变的情况进行量化评定。以专家诊断结果为效标,对两种量表对颅脑损伤所致人格改变的判定灵敏度和特异性以及两量表的内部条目进行分析。结果:①颅脑损伤所致人格改变专家评定及量表评定结果:经专家鉴定,116例颅脑损伤患者中诊断为颅脑损伤所致器质性人格改变的患者22例,占所有调查对象的19%,评估者的诊断一致性kappa值为0.86(P<0.01)。以专家诊断为效标,慢性脑器质性人格改变评定量表对本组颅脑损伤患者所致人格改变诊断的假阳性率为0,假阴性率为50%;自编脑外伤后人格改变评定量表的假阳性率为2.4%,假阴性率为4.5%。②两种量表评定颅脑损伤所致人格改变的内部条目分析:慢性脑器质性人格改变评定量表各条目评分结果显示有人格改变与无人格改变的患者在情绪不稳、情感淡漠或不协调、社会功能减退、个性改变、行为障碍5个条目的差异显著(t=2.082～5.921,P<0.01～0.05)。自编脑外伤后人格改变评定量表除认知偏离因子中的所有条目外,情感偏离因子中的情绪不稳,情感脆弱,易激惹,情感平淡、不关心人4个条目,意志行为偏离中的意志缺乏,欲望增强,行为冲动、不计后果,自我中心4个条目,人际关系偏离及原有人格变化及其所有条目上均有显著性差异(t=13.339～2.094,P<0.01～0.05)。结论:自编脑外伤后人格改变评定量表提高了对颅脑损伤所致人格改变诊断的灵敏度,其各条目能更准确地反映颅脑损伤所致人格改变的临床特点,但其信度和效度还需进一步完善。     

不同时辰刺激大鼠的交叉上核对血浆中皮质酮含量的影响

应用拉丁方设计，在不同体重组的大鼠，于不同时辰，对交叉上核采取不同强度的刺激，用放射免疫法测定外周血中皮质酮的含量。其结果显示：各体重组间无显著性差异，不同时辰血浆皮质酮的平均含量各组呈现基本相同的节律性变化，无论何时辰刺激交叉上核使之兴奋，均可显著提高血浆皮质酮的含量。完全损毁交叉上核后７２小时血浆皮质酮含量和正常对照组无显著性差异，且其节律性也没有出现明显变化。
