目的探讨采用K空间加权对比(KWIC)的三维径向梯度回波动态对比增强MR成像的团注后处理数据评估胰腺实性病变特征的可行性。材料与方法该回顾性研究经机构审查委员会同意,免除病人知情同意。共45例可疑胆道及胰腺病变的病人,接受小剂量(2mL钆喷酸葡胺)团注3.0TMR检查,采用径向KWIC技术。其中24例胰腺癌、8例胰腺神经内分泌肿瘤(PNET)、3例慢性胰腺炎和10例正常胰腺。使用动态对比增强(DCE)MR成像专用后处理软件程序,肿瘤及非肿瘤胰腺实质灌注参数测量如下:容积转运系数(Ktrans)及细胞外血管外容积分数,继而产生速度常数(kep)和60s内浓度曲线下的初始面积(iAUC)。DCEMR成像灌注参数组间比较采用方差分析。结果胰腺癌病人的Ktrans、kep和iAUC[分别为(0.042±0.023)min-1,(0.761±0.529)min-1和(2.841±1.811)mmol/s]显著低于胰腺正常的病人[分别为(0.387±0.176)min-1,(6.376±2.529)min-1和(7.156±3.414)mmol/s,均为P<0.05]。另外,PNETs与正常胰腺的kep值亦不同(P<0.0001),胰腺癌的Ktrans、kep和iAUC值与PNET的各值间的差异具有统计学意义(分别为P<0.0001,P=0.038和P<0.0001)。结论常规检查采用径向KWIC序列团注DCEMR成像通过后处理可以获得能够反映胰腺病变特征的潜在有效的灌注参数。

压力和剪力在自体脂肪移植中的作用

背景与目的由于供区损伤小、并发症发生率低及恢复时间快等特点，脂肪移植已成为整形外科中的常规项目。然而，仍有待确定最佳的脂肪移植技术。压力和剪力这两种临界变量均被定义为由区域划分的力。本研究中，我们将利用裸鼠模型检验压力和剪力在人类脂肪移植中的作用。方法对新鲜脂膜切除术标本行负压肿胀吸脂术。抽吸压力位-15inHg或-25inHg。将脂肪抽吸物以1200g／min离心，并注射至裸鼠侧腹部。对脂肪抽吸物行正压力处理至6atm，保持3min，然后注射至裸鼠，以检验正压力的作用。将脂肪抽吸物以1200g／min离心3min，然后以快速（3．0～5．0ml／s）和慢速（0．5～1．0ml／s）的方式注射至裸鼠，以检验剪切应力的作用。4周后，对脂肪移植物的质量和组织学进行分析。结果作为负压力，采取高压或低压行脂肪抽吸对抽吸物的质量和组织学影响均无差别。作为正压力，4周后发现，将正压力调至6atm并保持3min并未对移植物的质量及组织学造成影响。作为剪切应力的体内研究，缓慢注射的方式比快速注射其移植物质量多38％（P〈0．01）。而两种注射方式对移植物组织学的影响相似。结论调至-0．83atm的较高的抽吸压力并未对脂肪移植物的体内存活能力造成影响。调至6atm的正压力也并未影响脂肪移植物的存活能力。而剪切应力的程度，即注射推送速率，会对脂肪移植物的存活能力造成明显的影响。用较低剪切应力缓慢注射的脂肪移植物明显比用较高剪切应力注射的好。研究数据提示，与压力相比，剪切应力是影响脂肪移植物存活能力更重要的变量。

Theγ-ray emission from the W51 complex is widely acknowledged to be attributed to the interaction between the cosmic rays(CRs)accelerated by the shock of supernova remnant(SNR)W51C and the dense molecular clouds in the adjacent star-forming region,***,the maximum acceleration capability of W51C for CRs remains *** on observations conducted with the Large High Altitude Air Shower Observatory(LHAASO),we report a significant detection ofγrays emanating from the W51 complex,with energies from 2 to 200 *** LHAASO measurements,for the first time,extend theγ-ray emission from the W51 complex beyond 100 TeV and reveal a significant spectrum bending at tens of *** combining the"π^(0)-decay bump"featured data from Fermi-LAT,the broadbandγ-ray spectrum of the W51 region can be well-characterized by a simple pp-collision *** observed spectral bending feature suggests an exponential cutoff at~400 TeV or a power-law break at~200 TeV in the CR proton spectrum,most likely providing the first evidence of SNRs serving as CR accelerators approaching the PeV ***,two young star clusters within W51B could also be theoretically viable to produce the most energeticγrays observed by *** findings strongly support the presence of extreme CR accelerators within the W51 complex and provide new insights into the origin of Galactic CRs.

在兰州重离子研究装置的放射性束流线(HIRFL-RIBLL1)上,使用由三块双面硅微条探测器及环绕它的五个高纯锗探测器组成的探测器阵列,对丰质子核^(29)S的延迟衰变性质展开研究。本次实验获得了^(29)S的半衰期,为183(4)ms。首次实现了^(29)S的延迟测量,准确地获得了4条射线,得到了通过衰变布居到子核^(29)P低激发态的衰变分支比,并由此建立了^(29)S的部分衰变纲图。基于实验数据,研究了^(29)S→^(29)P/^(29)Al→^(29)Si镜像衰变过程中的同位旋对称性破缺。
