| 1 | 热处理对Zn−40Al−2Cu−2Si合金力学性能和磨损性能的影响显示文摘为了研究热处理对Zn−40Al−2Cu−2Si合金力学性能和磨损性能的影响,采用不同工艺对其进行热处理,包括均匀化后空冷(H1)、均匀化后炉冷(H2)、稳定化(T5)和淬火−时效(T6和T7)。通过金相、力学实验和磨损实验,研究不同热处理工艺对该合金力学性能和摩擦学性能的影响,并于SAE 65青铜进行对比。磨损实验使用环块式实验装置。结果表明,采用H1和T6热处理可提高合金的硬度、抗拉强度和抗压强度,除T6热处理外的其他热处理均可提高合金的断裂伸长率。经H1、T5和T6热处理后,合金的摩擦因数和磨损量减小,其中T6热处理后合金的摩擦因数和磨损量最低。因此,T6热处理为该合金应用于14 MPa压力下润滑摩擦的最佳工艺。与青铜相比,铸态和热处理态的Zn−40Al−2Cu−2Si合金磨损量较低、耐磨性较高。 | Temel SAVAŞKAN Zeki AZAKLI Ali Paşa HEKÌMOĞLU | 2021 | Transactions of Nonferrous Metals Society of China2021，31，9： | 3 |
| 2 | Post-operative computed tomography scan – reliable tool for quality assessment of complete mesocolic excision显示文摘BACKGROUND Quality control in colon cancer surgery is an ongoing debate ever since standardization proved to be highly efficient in improving survival in rectal cancer. Complete mesocolic excision(CME) is widely acclaimed as the new goldstandard in colon cancer resections, thus it is imperative to establish quality criteria of CME in order to make it easily understood and verified by surgeons worldwide. One simple and reproducible tool could be the measurement of arterial stumps postoperatively and a straightforward way to test its reliability is to test it in a comparative study between CME and non-CME surgery.AIM To validate arterial stump measurement as a surgical quality tool by comparing CME with conventional radical colectomies.METHODS This was a retrospective study, carried out on a prospective database. We collected data from two groups of patients, divided according to standard CME with D2 central vascular ligation(group A) and non-standardized surgery(group B). The two groups were compared with regard to the arterial stump length after right-and left-sided colectomies for colon cancer. The actual stump lengths of the ileocolic artery(ICA) and inferior mesenteric artery(IMA) were compared with their theoretical best D2 position of predicted ligation levels(D2 PLLs) for calculating the potential for improvement. Measurements on follow-up computed tomography scans were carried out by three observers. Pathological data were recorded(specimen length, lymph node yield) and correlated with stump length.RESULTS We analysed 58 colectomies. The stump lengths(mean ± SD) in group A were16.97 ± 4.77 mm for ICA and 31.70 ± 15.71 mm for IMA, whereas group B had 49.93 ± 20.29 mm for ICA and 67.24 ± 28.71 mm for IMA. Shorter lengths were obtained in group A, by a mean difference of 35.66 mm(χ~2 = 27.38, P < 0.001),which was significant for all types of colectomies. Except for a 5.85 ± 4.71 mm difference for right colectomies, all the ligations from group A significantly reached their potential height(0.26 ± 12.18 mm from D2 PLL; χ~2 = 0.005, P = 0.944).Apart from three left colectomies, group B failed to reach D2 PLL, by a mean difference of 32.14 ± 26.15 mm(χ~2 = 21.77, P < 0.001). The calculated improvement potentials were significantly shorter in group A than in group B, by a mean of 31.88 mm(χ~2= 22.13, P < 0.001). The large spread of results in group B showed that there is significant variability(P = 0.004) when compared to standard surgery. Significant correlations were found between stump length, specimen length and number of lymph nodes(P = 0.018 and P = 0.008 respectively). No statistical difference was found between observers' measurements(P = 0.866).CONCLUSION Arterial stump monitoring is a significant step in defining surgical quality, as longer stumps contain residual mesocolic tissue and correlate with major prognostic factors. | Cristian Livadaru Stefan Morarasu Tudor Cristian Frunza Florina A Ghitun Elena Florina Paiu-Spiridon Florina Sava Cristina Terinte Dan Ferariu Sorinel Lunca Gabriel Mihail Dimofte | 2019 | World Journal of Gastrointestinal Oncology2019，11，3： | 2 |
