目的人类运动涉及一组有限模块的协调激活,这些模块被称为肌肉协同,代表了中枢神经系统的运动控制策略。之前的大多数研究都侧重于孤立的肌肉激活,忽略了运动行为的模块组织。因此,为了加强对慢性踝关节不稳定(CAI)患者多关节运动时肌肉协调动态的理解,有必要探索其着地时的肌肉协同模式。方法共招募了22名单侧CAI患者和22名健康参与者。采用二阶微分方程递归模型处理表面肌电数据,经过滤波预处理后生成肌肉激活矩阵,将其输入非负矩阵分解模型以提取肌肉协同。利用K-means聚类算法和皮尔逊相关系数对肌肉协同进行分类。统计参数映射(SPM)被用于时间模块参数分析。结果CAI组和健康组中发现了4种肌肉协同模式。在肌肉协同1中,与健康对照组相比,臀大肌在CAI中的肌肉权重显著较高(P=0.0035)。肌肉协同2显示,健康组的股外侧肌肌肉权重显著较高(P=0.018),相反,在肌肉协同4中,CAI患者的股外侧肌的肌肉重量显著较高(P=0.030)。此外,在肌肉协同2中,CAI患者的胫骨前肌肌肉权重显著更高(P=0.042)。结论CAI患者表现出与健康组相似的模块化组织框架。对协同作用空间模块内振幅调整的分析阐明了胫骨前肌和臀大肌如何适应特定的协同以优化控制策略。不同运动模块中股外侧肌的肌肉权重差异产生了CAI中未探索过生物力学适应性,为康复方案提供了新的视角。

We present a method of 3D image mosaicing for real 3D representation of roadside buildings, and implement a Web-based interactive visualization environment for the 3D video mosaics created by 3D image mosaicing. The 3D image mo- saicing technique developed in our previous work is a very powerful method for creating textured 3D-GIS data without excessive data processing like the laser or stereo system. For the Web-based open access to the 3D video mosaics, we build an interactive visualization environment using X3D, the emerging standard of Web 3D. We conduct the data preprocessing for 3D video mosaics and the X3D modeling for textured 3D data. The data preprocessing includes the conversion of each frame of 3D video mosaics into concatenated image files that can be hyperlinked on the Web. The X3D modeling handles the representation of concatenated images using necessary X3D nodes. By employing X3D as the data format for 3D image mosaics, the real 3D representation of roadside buildings is extended to the Web and mobile service systems.

Traffic shaping is one of important control operation to guarantee the Quality of Service (QoS) in optical burst switching (OBS) networks. The efficiency of traffic shaping is mainly determined by token generation method. In this paper, token generation methods of traffic shaping are evaluated by using three kinds of probability distribution, and are analyzed in terms of burst blocking probability, through-put and correlation by simulation. The simulation results show that the token generation methods decrease the burst correlation of Label Switched Paths (LSPs), and solve traffic congestion as well. The different burst arrival processes have small impact on the blocking probability for OBS net works.

AIM： To examine the differences in the responses of normal and cirrhotic livers to partial hepatectomy in relation to the factors influencing liver regeneration.METHODS： Cirrhosis was induced in rats by administration of thioacetarnide. Untreated rats were used as controls. The control rats as well as the cirrhotic rats were subjected to 70% partial hepatectorny. At different time points after hepatectorny, the livers were collected and the levels of cytokines, growth factors and cell cycle proteins were analyzed.RESULTS： After hepatectomy, the cirrhotic remnant expressed significantly lower levels of cyclin D1, its kinase partner, cdk4, and cyclin E as compared to the controls up to 72 h post hepatectomy. Significantly lower levels of cyclin A and cdk2 were also observed while the cdk inhibitor, p27 was significantly higher. In addition, the cirrhotic group had lower IL-6 levels than the control group at all time points up to 72 h following resection.CONCLUSION： The data from our study shows that impaired liver regeneration in cirrhotic remnants is associated with low expression of cyclins and cdks. This might be the consequence of the low IL-6 levels in cirrhotic liver remnant which would in turn influence the actions of transcription factors that regulate genes involved in cell proliferation and metabolic homeostasis during the regeneration process.

Biliary tract cancers(BTCs)refer to invasive adenocarcinomas arising from the bile duct(intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma)and gallbladder(gallbladder cancer).Patients with BTCs typically present at an advanced stage due to a lack of early detection methods and non-specific symptoms;systemic chemotherapy is the cornerstone of treatment for these advanced *** plus cisplatin(GC)has been the standard treatment since the pivotal ABC-02 randomized phase 3 trial conducted in 2010(1).Moving beyond the era of GC,several triplet combination regimens have been proposed in recent years(Table 1).The combination of nab-paclitaxel(nab-P)and GC showed promising survival outcomes in a phase 2 trial(2),although it eventually failed to meet the primary endpoint of overall survival(OS)in a randomized phase 3 trial(3).Around the same time,TOPAZ-1(5)demonstrated that the programmed death ligand 1(PD-L1)inhibitor durvalumab combined with GC significantly improved the median OS[11.5 vs.12.8 months;hazard ratio(HR),0.80;95%confidence interval(CI):0.66–0.97;P=0.021]and median progression-free survival(PFS)(5.7 vs.7.2 months;HR,0.75;95%CI:0.63–0.89;P=0.001),with an objective response rate(ORR)of 26.7%.Moreover,KEYNOTE-966(6)found that the addition of programmed death-1(PD-1)inhibitor pembrolizumab also improved median OS(10.9 vs.12.7 months;HR,0.83;95%CI:0.72–0.95;P=0.0034),whereas the median PFS only showed numerical improvements(5.6 vs.6.5 months;HR,0.86;95%CI:0.75–1.00;P=0.023),with an ORR of 29%.Consequently,the combination of PD-1/PD-L1 inhibitors and GC has become the new standard of care for first-line treatment of patients with BTCs,establishing the new era of triplet combinations.
