背景:基于全直肠系膜切除(total mesorectal excision,TME)的根治性手术可能不是早期直肠癌的最佳一线治疗。选择性TME保留器官的策略可以减少治疗的不良反应,又不会显著影响肿瘤结果。该临床随机研究通过与TME比较,探讨器官保留策略的可行性。方法:TREC是一项在英国21个三级转诊中心进行的随机、开放标签的可行性研究。符合条件的受试者年龄≥18岁,分期为T2期或更早,最大直径不超过30 mm;排除淋巴结受累或转移的患者。患者按计算机随机分配(1:1)接受短程放疗保留器官,8~10周后行经肛门内镜显微手术(transanal endo⁃scopic microsurgery,TEM)或TME术。当TEM标本组织病理学特征提示局部复发风险增加时,患者被考虑计划早期转为TME。一项非随机前瞻性登记收集了认为不适合随机化的患者,因为每例患者都是按临床指征治疗的。主要终点为12、18和24个月的累积随机分组。次要结局为应用欧洲癌症研究与治疗组织(EORTC)QLQ C30和CR29量表对意向治疗人群的安全性、有效性和健康相关生活质量进行了评价。该研究已在ISRCTN注册中心注册,ISRCTN14422743。

Coordination complex of a copper cyanurate(Cu(Ⅱ)-CA) was transformed into coordination polymers upon the stimulus of extra Cu(Ⅱ) through “directed Ostwald ripening”. By increasing the molar ratio of Cu(Ⅱ) to CA, we obtained two coordination polymers with selective coordination sites: Cu(Ⅱ)-κ N(HCA)κ NCu(Ⅱ) and Cu(Ⅱ)-κ N(HCA)κ O-Cu(Ⅱ), which display disparate magnetic interactions.

In this work,competition between different supramolecular interactions is investigated based on a fibrous crystal composed of hydrogen-bonded cyanuric acid(CA)and amidinothiourea(ADT).Melamine(M)is found to prevail over ADT and bond to CA due to its stronger triple H-bonding affiliation,forming hollow microtubes assembled by oriented CAM crystalline arrays,as guided by the directionality of peripheral hydrogen ***,competitive interaction between hydrogen bonding and ionic/covalent bonding is demonstrated by mixing Ag+ions with the CA-ADT fibers,where sulfur atoms are abstracted from ADT molecules to produce Ag_(2)S *** in situ-formed Ag_(2)S serves as a binding glue to generate CA-ADT/Ag_(2)S composites with significantly enhanced mechanical strength compared to the pristine CA-ADT fiber pellet.

Using Linear and Non-Linear Techniques to Characterize Gait Coordination Patterns of Two Individuals with NGLY1 Deficiency

Individuals with NGLY1 Deficiency, an inherited autosomal recessive disorder, exhibit hyperkinetic movements including athetoid, myoclonic, dysmetric, and dystonic movements impacting both upper and lower limb motion. This report provides the first set of laboratory-based measures characterizing the gait patterns of two individuals with NGLY1 Deficiency, using both linear and non-linear measures, during treadmill walking, and compares them to neurotypical controls. Lower limb kinematics were obtained with a camera-based motion analysis system and bilateral time normalized lower limb joint time series waveforms were developed. Linear measures of joint range of motion, stride times and peak angular velocity were obtained, and confidence intervals were used to determine if there were differences between the patients and control. Correlations between participant and control mean joint waveforms were calculated and used to evaluate the similarities between patients and controls. Non-linear measures included: joint angle-angle diagrams, phase-portrait areas, and continuous relative phase (CRP) measures. These measures were used to assess joint coordination and control features of the lower limb motion. Participants displayed high correlations with their control counterparts for the hip and knee joint waveforms, but joint motion was restricted. Peak angular velocities were also significantly less than those of the controls. Both angle-angle and phase-portrait areas were less than the controls although the general shapes of those diagrams were similar to those of the controls. The NGLY1 Deficient participants’ CRP measures displayed disrupted coordination patterns with the knee-ankle patterns displaying more disruption than the hip-knee measures. Overall, the participants displayed a functional walking pattern that differed in many quantitative ways from those of the neurotypical controls. Using both linear and non-linear measures to characterize gait provides a more compre

Quantifying kinematic Tremor in an NGLY1-Deficient Individual: A Case Study

引用

Case Reports in Clinical Medicine 2024年第1期13卷 25-36页

NGLY1 Deficiency is an autosomal recessive congenital disorder that has been identified in less than 100 individuals. Most individuals with NGLY1 Deficiency display hyperkinetic movement disorders, including choreiform, athetoid, dystonic myoclonic, dyskinetic, and dysmetric movements. Developing a consistent and concise consensus on the classification and evaluation of tremors is essential to forward the research and treatment of tremors. It has also been reported that some individuals with NGLY1 Deficiency demonstrate tremor, but such tremor has never been formally investigated. The primary objective of this study is to determine if an individual with NGLY1 Deficiency demonstrates an identifiable tremor during a series of arm movements and, if so, describe the frequency and power characteristics of that tremor. Arm movement kinematics were obtained using a 16-camera Vicon system, and time series trajectory waveforms for three planes of a marker placed on the hand were developed. Custom MATLAB scripts were utilized to compute Fast Fourier Transformations of the data within the identified waveform segments. A mean frequency of 2.30 Hz (SD = 1.05) with a mean power of 5.02 |P1(f)| (SD = 4.63) suggests that our participant’s kinematic data did display a persistent tremor in both hands across all tasks and movement planes. Analyses of the reaching hand and the non-reaching hand suggest the participant displayed an action tremor in both postural and intention (kinetic) tremors. Future directions should include assessing additional individuals with NGLY1 Deficiency to determine if the tremor is a distinguishable disorder behavior. Additionally, evaluating other anatomical sites, such as the elbow, head, and lower limbs, would provide further insights into the characteristics of this tremor.
