BACKGROUND During emergency endoscopic retrograde cholangiopancreatography(ERCP),the safety and feasibility of performing one-stage endoscopic treatment for patients with acute cholangitis(AC)due to choledocholithiasis are *** To investigate the safety and feasibility of one-stage endoscopic treatment for moderate to severe *** We enrolled all patients diagnosed with moderate to severe cholangitis due to common bile duct stones from January 2019 to July *** outcomes were compared in this study between patients who underwent ERCP within 24 h and those who underwent ERCP 24 h later,employing a propensity score(PS)*** primary outcomes were intensive care unit(ICU)admission rates,ICU length of stay,and duration of antibiotic *** In total,we included 254 patients and categorized them into two groups based on the time elapsed between admission and intervention:The urgent group(≤24 h,n=102)and the elective group(>24 h,n=152).Ninety-three pairs of patients with similar characteristics were selected by PS *** urgent ERCP group had more ICU admissions(34.4%vs 21.5%,P=0.05),shorter ICU stays(3 d vs 9 d,P<0.001),fewer antibiotic use(6 d vs 9 d,P<0.001),and shorter hospital stays(9 d vs 18.5 d,P<0.001).There were no significant differences observed in adverse events,in-hospital mortality,recurrent cholangitis occurrence,30-d readmission rate or 30-d *** Urgent one-stage ERCP provides the advantages of a shorter ICU stay,a shorter duration of antibiotic use,and a shorter hospital stay.

高校内部权力的规范、有序、高效运行是高校权力规制的价值追求。党的十八大以来,高校惩治和预防腐败体系建设成效显著,权力腐败现象得到有效遏制,但影响相对较小、隐匿性强的权力失范现象仍时有发生。对高校内部权力失范案例进行梳理发现,“关系”是隐匿在权力失范背后的力量。从社会网络分析的视角看,高校内部权力主体的社会关系网络具有富集性、自主性和联通性等特征。高校存在“首长”主导型、跨部门“合谋”型、同部门“合谋”型三类关系结构截然不同的小团体。高校应从重视权力规制走向重视关系治理,从重视制度建设走向重视规则完善,从重视决策过程走向重视决策监管,将权力运行场域重塑、权力行为规范和权责意识强化有机统一起来,有效实现对权力失范的系统治理。

由于传统人驾车(traditional human-driven vehicles, HVs)驾驶行为会受到驾驶员的心理和生理活动的不确定性影响,可能使得车辆频繁地加减速,进而导致混合交通条件下网联自动车(connected and automated vehicles, CAVs)很难快速跟踪此行为.针对这一问题,首先提出一种提前预测传统人驾车行为的组合神经网络.在此基础上,考虑通信时延和车辆运动学特性,设计一种基于交通信息物理系统(transportation-cyber physical system, T-CPS)的混行车群内车辆协同控制策略,使其能够快速跟踪上传统人驾车行为,并对混行车群内网联自动车之间的串稳定性进行分析.最后,在混合交通条件下设置由1辆传统人驾车、1辆领头网联自动车和4辆跟随网联自动车形成的混行车群,利用下一代交通仿真(next generation simulation, NGSIM)车辆轨迹数据选出高质量传统人驾车状态,并通过仿真实验验证所提协同控制策略的有效性和可行性.由仿真实验结果可知,所提协同控制策略可以保证所有的网联自动车能够快速跟踪上传统人驾车行为,为解决新型混合交通带来的新问题提供一定的理论指导和借鉴.

Inhibiting SHP2 reduces glycolysis, promotes microglial M1 polarization, and alleviates secondary inflammation following spinal cord injury in a mouse model

引用

Neural Regeneration Research 2025年第3期20卷 858-872页

作者： Xintian Ding Chun Chen Heng Zhao Bin Dai Lei Ye Tao Song shuai huang Jia Wang Tao You Department of Orthopedics The First Affiliated Hospital of USTCDivision of Life Sciences and MedicineUniversity of Science and Technology of ChinaHefeiAnhui ProvinceChina Department of Orthopedics Provincial Hospital Affiliated to Anhui Medical UniversityHefeiAnhui ProvinceChina

Reducing the secondary inflammatory response, which is partly mediated by microglia, is a key focus in the treatment of spinal cord injury. Src homology 2-containing protein tyrosine phosphatase 2(SHP2), encoded by PTPN11, is widely expressed in the human body and plays a role in inflammation through various mechanisms. Therefore, SHP2 is considered a potential target for the treatment of inflammation-related diseases. However, its role in secondary inflammation after spinal cord injury remains unclear. In this study, SHP2 was found to be abundantly expressed in microglia at the site of spinal cord injury. Inhibition of SHP2 expression using siRNA and SHP2 inhibitors attenuated the microglial inflammatory response in an in vitro lipopolysaccharide-induced model of inflammation. Notably, after treatment with SHP2 inhibitors, mice with spinal cord injury exhibited significantly improved hind limb locomotor function and reduced residual urine volume in the bladder. Subsequent in vitro experiments showed that, in microglia stimulated with lipopolysaccharide, inhibiting SHP2 expression promoted M2 polarization and inhibited M1 polarization. Finally, a co-culture experiment was conducted to assess the effect of microglia treated with SHP2 inhibitors on neuronal cells. The results demonstrated that inflammatory factors produced by microglia promoted neuronal apoptosis, while inhibiting SHP2 expression mitigated these effects. Collectively, our findings suggest that SHP2 enhances secondary inflammation and neuronal damage subsequent to spinal cord injury by modulating microglial phenotype. Therefore, inhibiting SHP2 alleviates the inflammatory response in mice with spinal cord injury and promotes functional recovery postinjury.

针对短距/垂直起降战斗机高机动飞行的迫切需求及其矢量喷管机械结构复杂笨重的问题,提出了基于轴对称双喉道气动矢量喷管设计的双轴承旋转喷管,通过采用双轴承结构和双喉道气动矢量喷管相结合的方式,减少驱动结构,使喷管能更高效、轻便地实现短距/垂直起降,并且赋予了飞行器平飞模态高机动飞行的潜力。基于典型轴对称双喉道气动矢量喷管构型,开展了双轴承旋转喷管的型面设计和运动规律研究,利用数值模拟开展关键设计参数对喷管流场的影响研究,获得喷管的性能变化规律。结果表明,短距/垂直起降模态下,典型构型的双轴承旋转喷管推力矢量角最大可达108°,满足短距/垂直起降飞行器对喷管的要求。凹腔段的长短轴比值对喷管短距/垂直起降模态的性能影响较大,相同落压比条件下,长短轴比值越大,喷管的总推力系数越低,推力矢量角越大,并且推力矢量角最大差值达到41°。本文所提出的双轴承旋转喷管可为未来具备短距/垂直起降、高机动性能的飞行器动力系统提供一种新的解决方案。
