对耳轮过度前突为对耳轮的角度过锐，致使耳轮的位置相应后移，表现为与招风耳完全相反的畸形。畸形虽不十分明显，但影响美观。自１９９２年４月开始应用患侧耳廓软骨和耳后皮瓣对５例患者８只外耳进行治疗得到满意效果。认为文中所述方法是矫正对耳轮过度前突畸形的良好方法。     

Ethylene oxide does not extinguish the osteoinductive capacity of demineralized bone: A reappraisal in rats

We examined the influence of ethylene oxide (EO) and gamma irradiation on the osteoinductive capacity of demineralized bone. Demineralized bone powder prepared from Wistar rats was exposed to EO (55 °C or 40 °C) or gamma irradiation (25 KGy) or was preserved in ethanol. Sterilely-prepared bones served as controls. The powder was packed in a gelatin capsule and implanted for 6 weeks in muscles of 6-week-old female rats. Exposure of demineralized bone particles to EO 55 °C resulted in an almost complete loss of osteoinductivity. Irradiated bones lost about 40% of their osteoinductive capacity, while sterilization with EO at 40 °C resulted in only a slight alteration of the osteoinductivity, as assessed by the recovered weight ratio, calcium content, alkaline phosphatase activity measurements and histo-morphometry. Ethanol treatment had no influence on the new bone yield when compared to controls.

As EO exposure at 40 °C is a true sterilization procedure, it can be recommended in a clinical setting for its small effect on osteoinductive capacity as assessed experimentally in rats.     

顺铂对结直肠癌肿瘤浸润淋巴细胞杀伤活性的影响

为在临床选择有效的免疫化疗方案提供一定的理论依据，作者以结直肠癌肿瘤浸润淋巴细胞（ＴＩＬ）和顺铂（ＣＤＤＰ）为研究对象，对１６名手术治疗的结直肠癌患者，分别观察ＣＤＤＰ体内注射及体外预处理ＴＩＬ和Ｒａｊｉ细胞对ＴＩＬ表面标志和杀伤活性的影响。流式细胞仪检测结果显示，静脉注射ＣＤＤＰ能增加结直肠癌ＴＩＬ中ＣＤ３＋／ＣＤ４＋和ＣＤ３＋／ＣＤ８＋细胞含量，同时增强ＴＩＬ体外杀伤Ｒａｊｉ细胞的活性；而体外以ＣＤＤＰ处理Ｒａｊｉ细胞能增强其对结直肠癌ＴＩＬ杀伤的敏感性。作者认为，对于联合应用ＴＩＬ和ＣＤＤＰ治疗结直肠癌的临床效果有必要进一步研究。     

肾移植2,3,5年患者的免疫抑制用药分析

目的：分析肾移植后免疫抑制剂对长期存活的影响，寻找移植后不同时间合适的免疫抑制用药方案及其用药剂量。 方法：对肾移植一年以上、肾功能正常的４９７例患者进行５年连续随访。根据移植后２、３、５年的不同免疫抑制用药将患者分为三联、二联、传统二联治疗三组。统计各组的排异发生率，排异和无排异患者免疫抑制用药的种类、剂量及ＣｓＡ浓度，对排异患者追踪排异发生前１２个月内的药物更动情况。 结果：肾移植后２、３、５     

内痔粘膜及血管上皮细胞VEGF/FGF2的表达与内痔分期的相关性分析

目的 通过观察人体内痔不同分期粘膜及血管内皮细胞生长因子（VEGF）及碱性成纤维细胞生长因子（FGF2）的表达，探讨内痔的发生及发展机制。 方法 收集南方医院肛肠科门诊手术切除的Ⅰ、Ⅱ、Ⅲ期内痔标本134例（Ⅰ期42例，Ⅱ期45例，Ⅲ期47例），内痔周围正常肠壁组织40例作为对照，采用HE染色观察组织的病理学变化，采用免疫组织化学方法检测血管内皮细胞VEGF及FGF2的表达。 结果 正常组及Ⅰ期内痔黏膜层被覆上皮完整，未见扩张血管；Ⅱ期内痔黏膜层被覆上皮破坏，黏膜肌层破坏，黏膜层内见新生血管；Ⅲ期内痔黏膜层被覆上皮破坏，见血管管壁增厚迂曲，管腔扩张；与正常粘膜成纤维细胞相比VEGF在粘膜层成纤维细胞表达水平明显升高，并随分期增高而增高（F=883.961，P<0.01），FGF2也存在相同表达（F=656.013，P<0.01）；与正常组相比VEGF在血管内皮细胞表达水平明显升高，并随分期增高而增高（F=776.561，P<0.01），FGF2在血管内皮细胞的表达水平存在相同趋势（F=1066.458，P＜0.01）。 结论 VEGF及FGF2在内痔的形成过程中具有促进血管内皮细胞和粘膜下成纤维细胞增生的作用，同时可作为内痔发生发展的分子标志物。     

Involvement of ERK, p38 and NF-kappaB signal transduction in regulation of TLR2, TLR4 and TLR9 gene expression induced by lipopolysaccharide in mouse dendritic cells

Toll-like receptors (TLR) are sentinel receptors capable of recognizing pathogen-associated molecule patterns (PAMP) such as lipopolysaccharide (LPS) and CpG-containing oligonucleotides (CpG ODN). TLR2 and TLR4 are major receptors for Gram-positive and Gram-negative bacterial cell wall components, respectively. TLR9 is necessary for CpG signalling. LPS or CpG ODN can activate immature dendritic cells (DC) and induce DC maturation characterized by production of cytokines, up-regulation of co-stimulatory molecules, and increased ability to activate T cells. However, little is known regarding the regulation of TLR gene expression in mouse DC. In this study, we investigated the regulation of TLR2, TLR4 and TLR9 gene expression by LPS in murine immature DC. TLR2, TLR4 and TLR9 mRNA were up-regulated following LPS stimulation. The up-regulation of TLR9 expression coincided with significantly increased production of tumour necrosis factor-alpha induced by LPS plus CpG ODN. While inhibition of extracellular signal-related kinase and NF-kappaB activation suppressed the up-regulation of the expression of TLR2, TLR4 and TLR9 mRNA, inhibition of p38 kinase prevented the up-regulation of TLR2 and TLR4 mRNA expression but enhanced the up-regulation of TLR9 expression. These results demonstrated that TLR2, TLR4 and TLR9 gene expression was differently regulated by LPS in mouse immature DC. Up-regulation of TLR2, TLR4 and TLR9 expression by LPS might promote the overall responses of DC to bacteria and help to explain the synergy between LPS and other bacterial products in the induction of cytokine production.
