背景辅助细胞脂肪移植能提高脂肪移植的成活量。但能显著提高脂肪保留量的基质血管细胞群最佳浓度尚未得知。方法将获得的一部分脂肪待移植，另一部分提取基质血管细胞群。然后将提取出的不同浓度细胞（每200μl的脂肪含有1×10^4-1X10^7个细胞）与脂肪混合进行移植。移植后第8周，通过计算机断层扫描测定脂肪移植的成活量，并将移植的脂肪取出，比较结构和血管的组织学改变。结果加入的细胞浓度为每200μl脂肪含有1×10^4个细胞时，脂肪移植的成活量最大。加入的细胞量过多对脂肪移植的存活是不利的，加入1×10’个细胞时，脂肪的成活量最低，甚至比单纯脂肪移植更低。有趣的是，加入1×10^4个细胞时，血管化明显增加，炎症反应降低；而加入1×10^7个细胞与单纯脂肪移植相比，发生明显脂肪变性。结论我们的研究表明，可加入适量的基质血管细胞群以提高脂肪移植的成活量。虽然辅助细胞脂肪移植能促进移植脂肪的存活，但加入的细胞后期会与脂肪细胞争夺养分，因此，加人的细胞数量与其代谢要平衡。

目的尽管脂肪移植可以治疗多种软组织缺陷，但其结果仍有一定的不确定性。本研究中，我们将对使用一种自动、低剪切力装置或改良Coleman技术注射脂肪的物理性质进行对比。方法从9例患者处提取脂肪抽吸物，经过处理后采取改良Coleman技术或一种自动、低剪切力装置进行脂肪注射。通过一种2mm口径套管注入脂肪，并与微处理的脂肪进行对比。当组织开始失去其固态性质时，利用血流速度计测量其存储模量及剪切速率。同时，对脂肪组织的黏性进行测量，并通过载玻片实验定性评估每个治疗组的总产量。结果利用自动、低剪切力装置注射的脂肪，其物理性质与微处理的脂肪最接近。该自动装置组的脂肪存储模量（G’）比改良Coleman技术组高，而强度极限更延后。同样，测得该自动装置组的脂肪黏性与微处理组相当，比改良Coleman技术组的高。结论与改良Coleman技术相比，利用连于2mm插管的自动、低剪切力装置处理的脂肪抽吸物可以更好地保留脂肪组织完整的物理性质。本研究通过流变数据证实，该自动装置比改良Coleman技术对脂肪组织的损伤更小，其应用可能会增加移植脂肪的完整性。

背景与目的干细胞是一种吸引人的新发展的治疗方法，其适应证包括缺损组织的功能恢复。尽管多数干细胞疗法是新兴的，且处于实验阶段，但在世界各地，仍有许多诊所建议对干细胞感兴趣的患者接受干细胞治疗，这些治疗方法中的大多数是没有科学价值，缺少监管或患者保护的。方法笔者回顾了美容手术中加入干细胞的潜能以及存在的缺陷，并描述经美国食品药品管理局许可的适应证以及正在进行的脂肪干细胞临床试验。此外，利用“干细胞疗法”“干细胞治疗”或“干细胞面部提升”等检索词，对网站进行“snapshot”分析。结果尽管有管制机构（美国食品药品管理局）和专业学会（美国整形外科协会）的监管，笔者仍看到了令人担忧的手术广告，如干细胞面部年轻化、干细胞隆乳、甚至干细胞阴道年轻化。干细胞美容手术的市场营销和推广，并没有足够样本的临床证据支持。结论尽管干细胞具有巨大的潜能，但是美容市场充斥着未经证实的，有时甚至是欺骗性的宣传，可能会给患者带来风险。整形外科医师位于以干细胞为基础的再生医学的前沿位置，向患者介绍干细胞时，基于科学的数据，客观宣传其疗效，是及其重要的。

Peripheral nerve injuries induce a severe motor and sensory deficit. Since the availability of autologous nerve transplants for nerve repair is very limited, alternative treatment strategies are sought, including the use of tubular nerve guidance conduits(tNGCs). However, the use of tNGCs results in poor functional recovery and central necrosis of the regenerating tissue, which limits their application to short nerve lesion defects(typically shorter than 3 cm). Given the importance of vascularization in nerve regeneration, we hypothesized that enabling the growth of blood vessels from the surrounding tissue into the regenerating nerve within the tNGC would help eliminate necrotic processes and lead to improved regeneration. In this study, we reported the application of macroscopic holes into the tubular walls of silk-based tNGCs and compared the various features of these improved silk^(+) tNGCs with the tubes without holes(silk^(–) tNGCs) and autologous nerve transplants in an 8-mm sciatic nerve defect in rats. Using a combination of micro-computed tomography and histological analyses, we were able to prove that the use of silk^(+) tNGCs induced the growth of blood vessels from the adjacent tissue to the intraluminal neovascular formation. A significantly higher number of blood vessels in the silk^(+) group was found compared with autologous nerve transplants and silk^(–), accompanied by improved axon regeneration at the distal coaptation point compared with the silk^(–) tNGCs at 7 weeks postoperatively. In the 15-mm(critical size) sciatic nerve defect model, we again observed a distinct ingrowth of blood vessels through the tubular walls of silk^(+) tNGCs, but without improved functional recovery at 12 weeks postoperatively. Our data proves that macroporous tNGCs increase the vascular supply of regenerating nerves and facilitate improved axonal regeneration in a short-defect model but not in a critical-size defect model. This study suggests that further optimizatio

背景与目的超声辅助吸脂（ultrasound assisted liposuction，UAL）因其获取脂肪容易，且可让创伤和失血最小化，受到整形外科医师的青睐。但是，很少有研究报道这种方法获取的脂肪来源干细胞（adipose derived stromal cells，ADSCs）的质量。ADSCs在基于细胞的治疗方法中的作用也在急剧增长。因此，本研究比较了传统脂肪抽吸（suctionassistedliposuction，SAL）方法获得的ADSCs与UAL方法获得的ADSCs之间再生能力的差异。方法分别采用SAL和UAL方法，从健康人中获取脂肪并培养ADSCs；采用荧光辅助细胞分选（fluorescent assisted cell sorting，FACS）方法，分析ADSCs的产量。利用MTT比色法分析ADSCs的增殖能力，并在培养基中进行成脂和成骨分化诱导。将基因表达谱与qPCR进行对比。利用细胞染色比较成脂和成骨分化标记物。建立小鼠创伤愈合模型，在水凝胶支架上，分别播种采用SAL方法获取的ADSCs（SAL组）和采用UAL方法获取的ADSCs（UAL组），水凝胶组只加入水凝胶作为对照，同时比较3组的组织再生能力。结果UAL与SAL方法获得的ADSCs相比，在细胞数量和增殖能力方面的差异无统计学意义。油红O染色显示两者成脂分化能力没有差异，分化7d时，PPAR-γ受体和LPL的表达差异无统计学意义也证实了这一点（P〉0．05）。同样，碱性磷酸酶和茜素红染色也显示了两者相似的成骨分化能力，而且成骨标志物Runx-2、骨桥蛋白和骨钙蛋白的表达差异也无统计学意义（P〉0．05）。SAL组和UAL组的愈合速度明显大于水凝胶组（P〈0．05），SAL和UAL两组之间差异无统计学意义（P〉0．05）。结论与传统SAL方法相比，UAL方法可获得相等增殖能力的ADSCs，并用于以细胞疗法为基础的治疗。

Software engineering is broadly discussed as falling far short of expectations. Data and examples are used to justify how software itself is often poor, how the engineering of software leaves much to be desired, and how research in software engineering has not made enough progress to help overcome these weaknesses. However, these data and examples are presented and interpreted in ways that are arguably imbalanced. This imbalance, usually taken at face value, may be distracting the field from making significant progress towards improving the effective engineering of software, a goal the entire community shares. Research dichotomies, which tend to pit one approach against another, often subtly hint that there is a best way to engineer software or a best way to perform research on software. This, too, may be distracting the field from important classes of progress.
