1Characterisation and risk assessment of venous thromboembolism in gastrointestinal cancers显示文摘AIM To characterise venous thromboembolism(VTE) in gastrointestinal cancer and assess the clinical utility of risk stratification scoring. METHODS We performed a retrospective analysis using electronic patient records of 910 gastro-oesophageal(GO) cancer and 1299 colorectal cancer(CRC) patients referred to a tertiary cancer centre to identify the incidence of VTE, its relationship to chemotherapy and impact on survival.VTE risk scores were calculated using the Khorana index. Patients were classified as low risk(0 points), intermediate risk(1 to 2 points) or high risk(3 points). Data was analysed to determine the sensitivity of the Khorana score to predict VTE. RESULTS The incidence of VTE was 8.9% for CRC patients and 9.7% for GO cancer patients. Pulmonary emboli(PE) were more common in advanced than in localised CRC(50% vs 21% of events respectively) and lower limb deep vein thrombosis(DVT) were more common in localised than in advanced CRC(62% vs 39% of events respectively). The median time to VTE from cancer diagnosis was 8.3 mo for CRC patients compared to 6.7 mo in GO cancer. In localised CRC median time to VTE was 7.1 mo compared with 10.1 mo in advanced CRC. In contrast in GO cancer, the median time to VTE was 12.5 mo in localised disease and 6.8 mo in advanced disease. No survival difference was seen between patients with and without VTE in this cohort. The majority of patients with CRC in whom VTE was diagnosed had low or intermediate Khorana risk score(94% for localised and 97% in advanced CRC). In GO cancer, all patients scored either intermediate or high risk due to the primary site demonstrating a limitation of the risk assessment score in discriminating high and low risk patients with GO cancers. Additional risk factors were identified in this cohort including surgery, chemotherapy or hospital admission. Overall, 81% of patients with CRC and 77% of patients with GO cancer had one or more of these factors within 4 wk prior to diagnosis VTE. These should be factored into clinical risk assessment scores. CONCLUSION The Khorana score has low sensitivity for thrombotic events in CRC and cannot discriminate low risk patients in high risk cancer sites such as GO cancer.Robert L Metcalf Eamon Al-Hadithi Nicholas Hopley Thomas Henry Clare Hodgson Antony McGurk Wasat Mansoor Jurjees Hasan 2017World Journal of Gastrointestinal Oncology2017,9,9:10

3The Jinshajiang suture zone: tectono-stratigraphic subdivision and revision of age显示文摘Integrated study of rock assemblage, tectonic setting, geochemical feature, fossil contained and isotopic geochronology on the metamorphic mixed bodies, exposed in the Jinshajiang suture zone, suggests that one informal lithostratigraphic unit, the Eaqing Complex, and three tec-tono-stratigraphic units, the Jinshajiang ophiolitic melange, the Gajinxueshan Group and the Zhongxinrong Group, can be recognized there. It is first pointed out that the redefined Eaqing Complex might represent the Meso- to Neo-Proterozoic remnant metamorphic basement or mi-crocontinental fragment in the Jinshajiang area. The original rocks of it should be older than (1627 ±192) Ma based on the geochronological study. The zircon U-Pb age of plagiogranites within the Jinshajiang ophiolitic assemblage is dated for the first time at (294±3) Ma and (340±3) Ma respectively. The Jinshajiang ophiolite is approximately equivalent to the Ailaoshan ophiolite in the formation age, covering the interval from the Late Devonian to the汪啸风 lan Metcalfe 简平 何龙清 王传尚 2000Science China Earth Sciences2000,43,1:4

9Properties of diamond tool binders with fine carbonyl Ni powder additions显示文摘Fine Ni powder is often added to Co and bronze-based metal binder powders for diamond tool segments.Ni is a lower cost substitute for extra-fine Co powder and increases the toughness of Co-Fe diamond binders at the expense of lower hardness and bend strength.In bronze-based diamond binder segments,Ni increases hardness and yield strength.Several grades of Ni powder are used commercially with both Co and bronze-based diamond binders.This paper compares properties of diamond binders containing carbonyl Ni powders including standard Inco(?) T255,T123 PM and T 110 PM.Binder materials were made by ball milling or dry mixing of the fine carbonyl Ni and Fe powders with either XF Co or air atomized bronze(90/10 Cu/Sn) powders.Co-based powder blends were hot pressed at 20~35 MPa and 700℃to 900℃.Bronze-based powder blends were cold pressed and sintered at 840℃.Apparent density,apparent hardness and bend strength(TRS) were compared for different binder compositions and processing conditions.Stephenson T F Korotkin M Metcalfe S 2008金刚石与磨料磨具工程2008,28,S1:2
