目的探讨血清神经元特异性烯醇化酶(NSE)、同型半胱氨酸(Hcy)及8-羟基脱氧鸟苷酸(8-OHdG)在急性脑梗死患者中的表达及意义。方法选取该院2013年3月至2015年12月神经内科收治的100例急性脑梗死患者为脑梗死组,选择100例同期在该院健康体检者为对照组,脑梗死组再根据梗死体积将患者分为3组,梗死区大于10cm^3为大体积梗死组(L组),5~10cm^3为中体积梗死组(M组),<5cm^3为小体积梗死组(S组)。比较脑梗死组与对照组,L组、M组、S组血清NSE、HCY及8-OHdG水平。采用Pearson相关检验对HCY、8-OHdG、NSE与脑梗死体积、神经功能缺损、预后情况进行相关性分析。结果观察组患者HCY、8-OHdG及NSE水平较对照组高,差异有统计学意义(P<0.05),L组较M组、S组患者HCY、8-OHdG及NSE水平高,差异有统计学意义(P<0.05),HCY、8-OHdG及NSE与脑梗死体积、神经功能缺损呈正相关,与预后情况呈负相关。结论血清NSE、HCY及8-OHdG在急性脑梗死患者中升高,且随着梗死体积的增大逐渐增高,血清NSE、HCY及8-OHdG可用于病情及预后评估。

Lithospheric structure beneath the northeastern Qinghai-xizang Plateau is of vital significance for studying the geodynamic processes of crustal thickening and expansion of the Qinghai-xizang Plateau. We conducted a joint inversion of receiver functions and surface wave dispersions with P-wave velocity constraints using data from the Chin Array Ⅱ temporary stations deployed across the Qinghai-xizang Plateau. Prior to joint inversion, we applied the H-κ-c method(Li JT et al., 2019) to the receiver function data in order to correct for the back-azimuthal variations in the arrival times of Ps phases and crustal multiples caused by crustal anisotropy and dipping interfaces. High-resolution images of vS, crustal thickness, and vP/vSstructures in the Qinghai-xizang Plateau were simultaneously derived from the joint inversion. The seismic images reveal that crustal thickness decreases outward from the Qinghai-xizang Plateau. The stable interiors of the Ordos and Alxa blocks exhibited higher velocities and lower crustal vP/vSratios. While, lower velocities and higher vP/vSratios were observed beneath the Qilian Orogen and Songpan-Ganzi terrane(SPGZ), which are geologically active and mechanically weak, especially in the mid-lower *** or thermal erosion of the lithosphere triggered by hot asthenospheric flow contributes to the observed uppermost mantle low-velocity zones(LVZs) in the SPGZ. The crustal thickness, vS, and vP/vSratios suggest that whole lithospheric shortening is a plausible mechanism for crustal thickening in the Qinghai-xizang Plateau, supporting the idea of coupled lithospheric-scale deformation in this region.

A monocloual antibody, SZ-2, reacts specifically on human platelets and megakaryocytes. The plate-lets from 10 normal donors are bound to 15,200±4,100 SZ-2 molecules/platelet. The antigen recognizedby SZ-2 is chymotrypsin-sensitive but neuraminidase-insensitive, and has been identified as glycoproteinIb (GPIb) by an affinity chromatography technique. SZ-2 is different from other monoclonal antibodiesto GPIb. It inhibits not only platelet aggregation induced by ristocetin, but also platelet aggregation in-duced by collagen (type Ⅰ) and by PAF. SZ-2 also inhibits platelet serotonin and β-thromboglobulinrelease in response to these stimuli.
