BACKGROUND In patients with metastatic colorectal cancer(mCRC),the treatment options are limited and have been proved to be affected by rat sarcoma virus(RAS)mutational *** RAS wild-type(wt)patients,the combination of antiepidermal growth factor receptor(EGFR)monoclonal antibodies with chemotherapy(CT)is more effective than CT *** the other hand,RAS-mutated patients are not eligible for treatment with anti-EGFR *** SUMMARY Eleven patients with initially RAS-mutated mCRC were followed from diagnosis to May *** the time of cell-free DNA determination,five patients had undergone one CT line,five patients had undergone two CT lines,and one patient had undergone three CT lines(all in combination with bevacizumab).At the second and third treatment lines[second line(2L),third line(3L)],patients with neo-RAS wt received a combination of CT and *** neo-RAS wt patients treated with anti-EGFR,our findings indicated an increase in progression-free survival for both 2L and 3L(14.5 mo,P=0.119 and 3.9 mo,P=0.882,respectively).Regarding 2L overall survival,we registered a slight increase in neo-RAS wt patients treated with anti-EGFR(33.6 mo vs 32.4 mo,P=0.385).At data cut-off,two patients were still alive:A RAS-mutated patient undergoing 3L treatment and a neo-RAS wt patient who received 2L treatment with anti-EGFR(ongoing).CONCLUSION Our case series demonstrated that monitoring RAS mutations in mCRC by liquid biopsy may provide an additional treatment line for neo-RAS wt patients.

Impact of China’s Outward Foreign Direct Investment on Enterprise Performance

引用

Journal of Donghua University(English Edition) 2019年第5期36卷 513-520页

作者： XU Qiqi WANG Lei id Bouichou Said Glorious Sun School of Business and Management Donghua University

The present study seeks to address two fundamental questions.(1)Does outward foreign direct investment(OFDI)enhance enterprise performance ultimately?(2)How does this effect come about?A new dataset from the years 2011 to 2016 based on the micro-data of 88 Chinese multinational-listed enterprises was used to test research hypotheses with the mediating effect modeling *** study results reveal that:(1)the investment intensity has a positive influence,while investment span has a negative influence on enterprise performance;(2)the enhanced innovation capability can considerably increase the enterprise performance,while investment intensity and span both hinder the upgrading of innovation capability;and(3)the innovation capability of an enterprise plays a partial intermediary role among investment span and enterprise ***,there is no mediating effect between investment intensity,innovation ability,and enterprise performance.

Depth to the bottom of magnetic layer in South America and its relationship to Curie isotherm,Moho depth and seismicity behavior

引用

Geodesy and Geodynamics 2018年第1期9卷 93-107页

We have estimated the DBML（depth to the bottom of the magnetic layer） in South America from the inversion of magnetic anomaly data extracted from the EMAG2 grid. The results show that the DBML values, interpreted as the Curie isotherm, vary between -10 and -60 km. The deepest values（〉-45） are mainly observed forming two anomalous zones in the central part of the Andes Cordillera. To the east of the Andes, in most of the stable cratonic area of South America, intermediate values（between -25 and-45 km） are predominant. The shallowest values（〈-25 km） are present in northwestern corner of South America, southern Patagonia, and in a few sectors to the east of the Andes Cordillera. Based on these results, we estimated the heat flow variations along the study area and found a very good correlation with the DBML. Also striking is the observation that the thermal anomalies of low heat flow are closely related to segments of flat subduction, where the presence of a cold and thick subducting oceanic slab beneath the continent, with a virtual absence of hot mantle wedge, leads to a decrease in the heat transfer from the deeper parts of the *** comparing our results with the Moho depths reported by other authors, we have found that the Curie isotherm is deeper than Moho in most of the South American Platform（northward to -20°S）, which is located in the stable cratonic area at the east of the Andes. This is evidence that the lithospheric mantle here is magnetic and contributes to the long wavelength magnetic signal. Also, our results support the hypothesis that the Curie isotherm may be acting as a boundary above which most of the crustal seismicity is concentrated. Below this boundary the occurrence of seismic events decreases dramatically.

Influence of Process Variables on the Structure of Mechanically Alloyed Ti_3Al-base Intermetallics

Rare Metals 1993年第4期12卷 241-249页

During mechanical alloying variables such as the type of mill,milling intensity,milling time,milling at- mosphere and ball-to-powder weight ratio(BPR)affect the morphology and constitution of the product. The effect of milling time,milling atmosphere and BPR on the nature of the product formed in mechanical- ly alloyed pure Ti and blended elemental binary Ti-Al,and ternary Ti-AI-Nb alloy powders was described. Mechanical alloying of pure titanium results,after long milling times,in the formation of an fcc *** the binary alloy,a solid solution of aluminum in titanium,an amorphous phase,and a fcc phase form with increasing milling *** fcc phase,which is probably a result of TiN formation,occurs more rapidly in air or nitrogen than in an inert *** of the B2 phase in the ternary alloys depends both on alloy composition and the milling atmosphere,with 100％ formation in all atmospheres in Ti-25Al-25Nb but not in Ti-24Al-11Nb,and an inert atmosphere favoring *** times required for the formation of the different phases decrease as the BPR increases;but their sequence is *** on this infor- mation,“milling maps”which describe phase formation as a function of the BPR and milling time are con- *** from the milling balls increased as the BPR was increased.

许多医学学科的资料表明,唾液可为较多的疾病及临床的需要提供一简便、无创性的诊断途径。样本来集最常用的采样方法为吐出全部唾液,该液为一种腮腺、颌下腺及舌下腺分泌液为主的混合液,其中含有小唾液腺及龈沟分泌液。后者主要为血浆渗出液,液中可含有细胞,龈炎或牙周炎时也可含有炎性产物。由于大量细菌不断地从牙面及软组织表面脱落,以及上皮细胞的脱落,所以常需对唾液进行离心处理,以获取澄清样品,但有时唾液中的细菌及细胞有一定诊断价值。未受刺激的唾液通常是由被动流口水的方式采集,
