The objective of this guideline is to outline the role of magnetic resonance imaging(MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury(SCI).Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic *** review focused on longitudinal studies that controlled for baseline neurologic status.A multidisciplinary Guideline Development Group(GDG) used this information,their clinical expertise,and patient input to develop recommendations on the use of MRI for SCI *** on GRADE(Grading of Recommendation,Assessment,Development and Evaluation),a strong recommendation is worded as " we recommend," whereas a weaker recommendation is indicated by "we suggest." Results Based on the limited available evidence and the clinical expertise of the GDG,our recommendations were:(1) "We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention,when feasible,to facilitate improved clinical decision-making"(quality of evidence,very low) and(2) "We suggest that MRI should be performed in adult patients in the acute period following SCI,before or after surgical intervention,to improve prediction of neurologic outcome "(quality of evidence,low).Conclusions These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI.

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。

背景与目的脂肪移植是一项很有前景的软组织填充增大技术，但移植疗效持久性存在高度不可预知性，而且影响移植成活率的因素尚未明确。因为具有分化的潜能和释放生长因子的能力，脂肪来源干细胞（adipose-derivedstemcells，ADSCs）可在移植修复过程中起关键作用。我们旨在确定ADSCs在人体脂肪中呈现的生物学特性是否与移植体积的体内效果保持存在关联。方法利用标准的离心分离技术对从8例人体受术者获取的脂肪抽吸物进行处理，然后将其注射至6周龄无胸腺裸鼠躯体两侧。测量移植物的质量和体积，于移植后8周进行包含针对血管的CD31^＋染色的组织学评估。从各供体脂肪抽吸物中分离获取基质血管细胞群（stromalvascularfraction，SVF），利用多参数流式细胞术对其表面标记物进行分析，并对其增值、分化能力和正常含氧量／低含氧量血管内皮细胞生长因子（vas—cularendothelialgrcwlhfactor，VEGF）的分泌情况进行实验研究。结果从不同供体中获取的SVF，其CD34^＋祖细胞含量百分率存在较大差异，其平均值为21．3％±15．O％（X±s）。SVF细胞的增殖速率和成脂潜能在不同供体间存在较为中等差异。在小鼠异种移植研究中，移植后8周体积保存的量约为36％～68％，总体平均值为52％±11％。SVF中CD34^＋祖细胞的含量与脂肪移植效果持久性方面存在较强的关联（p〈0．05）。结论在不同患者之间，其脂肪组织的内在生物学特性存在差异。特别是SVF中CD34^＋祖细胞的浓度可能是影响脂肪移植持久性的因素之一。

节约用水是解决新时代我国水安全方面最突出的"水资源短缺、水生态损害、水环境污染"新三大问题的根本性措施,也是推进生态文明建设的重要举措。在促进节约用水方面存在的问题不少,当前主要难点问题是促进节约用水的理念落后、对水资源的短缺且稀缺认识存在偏差、节约用水的动力机制缺失。在对难点问题进行深入分析的基础上,依据习近平生态文明思想,结合现行有效政策,借鉴国外先进经验,研究提出了有针对性的政策建议,即树立符合生态文明要求的促进节约用水理念、开展有针对性节约用水宣传教育、充分发挥市场配置水资源的决定性作用。
