Selection of allografts for impaction bone grafting for bone defect reconstruction on the acetabular side

Chinese Medical Journal 2010年第21期123卷 3143-3147页

作者： XU Zheng-jian he rong-xin Department of Orthopaedic Surgery Second Affiliated Hospital School of Medicine Zhejiang University Hangzhou Zhejiang 310009 China

Objective To review the choices of allografts for bone defect reconstruction in acetabular revision surgery using the technique of impaction bone *** sources The data cited in this review were mainly obtained from articles listed in PubMed that were published from January 1993 to July 2009. The search terms were ＂impaction bone grafting＂, ＂particle size＂, ＂mechanical property＂and ＂biological behavior＂.Study selection Articles relevant to the choices of allografts and their results for bone defect reconstruction on the acetabular side were *** Different choices of allografts, including the particle size, process of irradiation or fat reduction, composition and particle grade, are made to improve the survival rate of a prosthesis in acetabular revision surgery. This review,which compares both mechanical and biological factors, summarizes the experimental and clinical results for different *** Fresh frozen cancellous allografts with particle sizes ranging from 7 to 10 mm are a favorable choice for reconstruction of bone defects of American Academy of Orthopedic Surgeons （AAOS） types Ⅱ （cavitary defect） and Ⅲ（combined cavitary and segmental defect） on the acetabular side. A fat-reducing procedure with saline or solvent/detergent is controversial. Adding autologous marrow into irradiated allografts, which provides reliable mechanical stability and biological safety, may be a substitute for fresh frozen allografts. Cortical bone can be a supplementary material in cases of insufficiency of cancellous allografts. Cartilage should be excluded from the graft material. Further research is required to demonstrate the best particle grade, and randomized controlled trials in clinical practice are required to obtain more information about the selection of allografts.

Chinese Medical Journal 2010年第21期123卷 3020-3023页

Background Isolated patellofemoral osteoarthritis is not uncommon. Surgical treatment of isolated patellofemoral arthritis remains controversial and poses a challenging treatment dilemma. The present study aimed to evaluate the short-term results of patellofemoral arthroplasty for patients with isolated patellofemoral *** We analyzed 11 patellofemoral arthroplasties performed from March 2006 to September 2009 in 11 patients with isolated patellofemoral arthritis. The patients comprised 2 males and 9 females with an average age of 53.7 years （range, 46-74 years）. Standard weightbearing radiographs were taken in the anteroposterior, lateral, and 45° axial *** knee pain and functional status were evaluated by the Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） scales and American Knee Society （AKS） scores. For comparison, 23 total knee arthroplasties in 23 patients with primary tibiofemoral osteoarthritis were matched according to age, gender, bilaterality and body mass *** duration of follow-up was 23.7 months （range, 12-47 months）.Results The majority of the 11 patients experienced improvement in their patellofemoral symptoms after patellofemoral arthroplasty. The WOMAC scores improved considerably by 7.4 points with respect to pain and by 5.2 points with respect to function. The AKS scores also improved considerably by 23.9 points with respect to pain and 44.3 points with respect to function. Although the clinical outcomes after patellofemoral arthroplasty were not better than those after total knee arthroplasty, patellofemoral arthroplasty exhibited advantages in the shorter operation time, lower blood loss and increased postoperative range of motion. At the latest follow-up, there was no clinical or radiographic evidence of patellofemoral maltracking, loosening or *** On the basis of our experience in this relatively small series of patients with a short-term follow-up,patellofemoral arthroplasty i

乳腺癌的病因尚未明确,已知的危险因素包括生殖因素、影响体内性激素水平因素和遗传易感因素,但这些因素也只能解释约50%乳腺癌病例。近年来有研究试图从病毒感染的角度探讨乳腺癌的病因,EB病毒(Epstein-Barr virus,EBV)正是研究热点之一。但EBV与乳腺癌的关系仍存在着很大的争议。本文就EBV生物学特点、EBV与乳腺癌的相关性研究(包括癌组织中的EBV检测、血清学研究、细胞学实验和临床特点分析)作一综述,并提出目前存在的问题和今后研究的方向。

本文以生姜为原料,通过两种不同的提取方式研究姜油中的风味物质,采用气质联用(GC-MS)技术对得到的样品进行风味物质的测定,并运用主成分分析法(PCA)比较两种不同的提取方式所得到的风味物质之间的区别。结果表明:超临界CO_2萃取法得到的姜油共检测出83个峰,乙醇浸提法共检测出51个峰,得到的风味物质主要有6大类,包括烯烃类、酮/酚类、酸酯类、醛类、醇类和烷烃类,其中贡献率最大的是烯烃类和酮/酚类,累计贡献率达到95.544%。超临界CO_2萃取得到的姜油不仅感官品质上优于乙醇浸提法得到的姜油,其风味物质的相对含量也明显多于乙醇浸提法得到的姜油,为以后姜油风味物质的开发利用提供一定的参考依据。

选用乙醇为溶剂提取大蒜油,研究不同工艺条件下的大蒜油品质,以其呈香成分保留程度作为评价品质的指标,对比考察乙醇浓度、料液比、提取时间及提取温度4个因素对大蒜油品质的影响。分别选用动态针捕集(Needle Trap)、固相微萃取(SPME)2种样品萃取分离技术与气相色谱-质谱联用(GC-MS)对提取的大蒜油成分进行对比分析,探讨Needle Trap-GC-MS在测定挥发性呈香成分中的适用性。结果发现:选用浓度为85%的乙醇、大蒜粉末按1∶8加入,在60℃下萃取4h得到大蒜油品质最佳,采用SPME-GC-MS可从中鉴定得到26种成分,而Needle Trap-GC-MS可分离鉴定出36种成分,Needle Trap-GC-MS分析所得风味代表物质种类较多且相对含量较高,表明动态针捕集技术在富集挥发性香气物质用于鉴定分析方面具有一定的优势。
