血栓诱发的心脑血管疾病的发病率在世界范围内不断增长,严重威胁人类健康。研究表明,形成血栓的三个因素分别为血流缓慢、血液高凝状态以及血管损伤。根据血栓形成的机制,抗血栓药物被分为三类,包括抗凝剂、血小板抑制剂和纤维蛋白溶解剂。由于凝血系统和抗凝血系统在血栓形成的过程中扮演着重要的作用,因此受到了越来越多的关注。目前,具有抗凝活性的新型化合物正不断涌现,一定程度上缓解了早期获批血栓治疗药物临床应用的一些问题,如出血风险高、起效慢、治疗窗口窄等。本文首先阐述了凝血机制以及血栓形成的原因和机制,然后主要总结了近年来研究报道的抗凝血活性化合物及潜在的抗血栓候选物,并对部分化合物的化学结构-药理活性关系进行了分析,以期促进开发具有抗凝血生物活性的分子,用于治疗血栓性疾病。

Patients with complete spinal cord injury retain the potential for volitional muscle activity in muscles located below the spinal injury ***,because of prolonged inactivity,initial attempts to activate these muscles may not effectively engage any of the remaining neurons in the descending pathway.A previous study unexpectedly found that a brief clinical round of passive activity significantly increased volitional muscle activation,as measured by surface *** this study,we further explored the effect of passive activity on surface electromyographic signals during volitional control tasks among individuals with complete spinal cord *** patients with chronic complete thoracic spinal cord injury were *** electromyography data from eight major leg muscles were acquired and compared before and after the passive activity *** results indicated that the passive activity led to an increased number of activated volitional muscles and an increased frequency of *** the cumulative root mean square of surface electromyography amplitude for volitional control of movement showed a slight increase after passive activity,the difference was not statistically *** findings suggest that brief passive activity may enhance the ability to initiate volitional muscle activity during surface electromyography tasks and underscore the potential of passive activity for improving residual motor control among patients with motor complete spinal cord injury.

In the paper,an experiment investigation was conducted for one-and two-degree of freedom vortex-induced vibration（VIV） of a horizontally-oriented cylinder with diameter of 11 cm and length of 120 *** the experiment,the spring constants in the cross-flow and in-line flow directions were regulated to change the natural vibration frequency of the model *** was found that,in the one-degree of freedom VIV experiment,a ＂double peak＂ phenomenon was observed in its amplitude within the range of the reduced velocities tested,moreover,a ＂2T＂ wake appeared in the vicinity of the second *** the two-degree of freedom VIV experiment,the trajectory of cylinder exhibited a reverse ＂C＂ shape,i.e.,a ＂new moon＂ *** analysis of these data,it appears that,besides the non-dimensional in-line and cross-flow natural vibration frequency ratios,the absolute value of the natural vibration frequency of cylinder is also one of the important parameters affecting its VIV behavior.
