Based on summarizing of the effect of mantle-derived fluid on the formation of ores, especially on gold ore, and with the latest investigations, such as the formation of ore from the action of shallow-deep fluid, the transportation effect of the thermal energy by mantle-derived fluid, this paper mainly aims at the effect of mantle-derived fluid on the generation of hydrocarbons. With the proof from geochemistry and fluid inclusion, it was suggested that the mantle-derived fluid not only supplied source materials for hydrocarbons, but also supplied essential energy and matter necessary for the generation of hydrocarbons. The mantle-derived fluid had a good effect, but at the same time it had an adverse effect under specific conditions, on the formation of reservoirs. This paper also discusses the future direction and significance of studying mantle-derived fluid.

Based on guided wave theory and considering the grouted rock bolt as waveguide medium, we have constructed a three dimensional model of grouted rock bolt with the dynamics of finite difference numerical simulation software FLAC3D4.0, and simulated the propagation behavior of the guided wave in the full grouted rock bolt. The simulated waveform and wave velocity matched well with the experimental results. We have made a more in-depth and comprehensive study of the wave velocity, wave component and attenuation characteristics of the guided wave propagating in rock bolt, and found some new characteristics and phenomena. In addition, some phenomena that haven’t been explained in the previous researches have also been discussed in this paper. The result showed that when guided wave propagates in grouted rock bolt, after the body wave decays, there is still the interface wave-Stoneley wave that does not decay in the axial direction of the bolt. The findings can provide some reference for rock bolt testing and the selection of the optimal excitation wave of testing.

This study presents noble gaseous data of the corundum megacrysts from the Cenozoic basalts in Changle, Shandong Province, eastern China. It is known that no noble gaseous data of corundum megacryst have been documented before. The 3He/4He ratios (1.13-7.37 Ra) of the corundums from Changle vary from atmosphere to MORB values; the 20Ne/22Ne (9.67-10.75) and 21Ne/22Ne (0.0280-0.0372) data define two linear trends on Ne three-isotope diagram, respectively, along the MFL and the correlation line between atmosphere and MORB; the 38Ar/36Ar (0.177-0.194) ratios, the 40Ar/36Ar (280.9 -404.2) ratios and the 128-136Xe/132Xe ration with obvious 129Xe excess are generally higher than at-mospheric component, but the 40Ar/36Ar ratios are much closer to atomospheric ratio. The isotopic compositions of noble gases (particularly for He and Ar) of the corundums are similar to those of py-roxene, anorthoclase megacrysts, and mantle-derived xenoliths from this area, and those of man-tle-derived xenoliths from several areas in eastern China. Therefore, the noble gases trapped in the corundums probably are from mantle source, representing a ‘mixed fluid' produced by the interaction between the lithospheric mantle and fluids releasing from the convective plate. Both the noble gas isotopic compositions and the oxygen isotopic compositions of the solid corundums are not the characteristics of crustal source. These suggest that the corundums crystallized from mantle-derived magmas with minimal crustal contamination.

In the updip portion of the Yulin Gas Field in the Ordos Basin, there are no any structural, stratigraphic and sedimentary lithologic seals. Using thin-section petrography, ultraviolet fluorescence microscopy, micro-thermometry and Raman microspectrometry, this paper finds out the diagenetic trap and studies the diagenetic history of this field. It was revealed that three phases of diagenesis and hydrocarbon charging happened in late Triassic, late Jurassic and the end of early Cretaceous respectively. In the first two phases, acid geofluid entered the reservoir and caused dissolution and cementation. Although the porosities had been increased, further compaction accompanying re-subsidence resulted in tight sandstone and conglomerates. Till the end of the early Cretaceous, bulk of gas migrated into the tight reservoir. Cementation, however, kept on in the updip portion of this field due to low gas saturation and formed the diagenetic trap. The mechanism for gas accumulation was changed from deep basin gas to diagenetic trap, which offers a sealing condition that can retain gas for much longer time.

Dear Editor, Wheat aphids are serious pests in wheat growing areas of China, and can lead to from 10% to over 30% reduction in wheat production （Wang et al., 2006）. The main wheat aphids are Sitobion avenae （Fabricius）, Rhopalosiphum padi （Linnaeus）, Metopolophium dirhodum （Walker）, and Schiza- phis graminum （Rondani）. In the Huang-Huai area of China, the dominant wheat aphid species are S. avenae and R. padi. For many years, farmers have applied chemical pesticides to control wheat aphids. The number of wheat aphids in north China has increased from year to year, probably due to the increased resistance to insecticides.

目的探索老年维持性血液透析(maintenance hemodialysis,MHD)病人的内在能力(intrinsic capacity,IC)及其影响因素。方法采用方便抽样法,抽取东南大学附属中大医院血液净化中心2023年1—6月老年MHD病人。收集病人一般资料,并进行IC评估,评估内容包括采用简易躯体能力测试评估运动能力、采用微型营养评估简表评估营养状态、采用MMSE量表评估认知功能、采用Zung抑郁自评量表评估抑郁状态,并自述视力/听力下降评估感觉。结果本研究共调查老年MHD病人175例,平均年龄为(69.78±6.92)岁,其中男性105例(60.00%),平均透析龄为(66.91±55.36)个月,IC总平均得分为(2.25±1.03)分。其中,IC较好(≥3分)的老年MHD病人53例(30.29%)、IC欠佳(<3分)的老年MHD病人122例(69.71%)。多因素Logistic回归分析结果显示,血浆白蛋白是老年MHD病人IC的保护因素,年龄和β2微球蛋白是老年MHD病人IC的独立危险因素。结论老年MHD病人IC下降普遍存在,升高血浆白蛋白水平可能有益于提升老年MHD病人的IC。

目的探讨老年维持性血液透析(maintenance hemodialysis, MHD)病人发生左心室舒张功能障碍(left ventricular diastolic dysfunction, LVDD)的影响因素。方法选取2022年3—12月于东南大学附属中大医院血液净化中心行透析治疗的老年MHD病人178例,根据是否发生LVDD将病人分为LVDD组和非LVDD组。收集并比较2组一般资料、实验室指标及心脏结构相关参数,采用Logistic回归分析老年MHD病人发生LVDD的危险因素。结果 LVDD组透析龄和舒张末室间隔厚度(IVST)、甲状旁腺激素、脑钠肽水平显著高于非LVDD组(P<0.05)。多因素Logistic回归分析显示,透析龄(OR=1.284,95%CI:1.102~1.497)和IVST(OR=11.434,95%CI:5.942~118.404)为老年MHD病人发生LVDD的危险因素(P<0.01)。结论临床对透析龄较长、IVST较高的老年MHD病人要警惕LVDD的发生。
