目的探讨内镜下放射状切开联合局部注射曲安奈德(ERITA)治疗食管良性狭窄的有效性及安全性。方法回顾性分析2018年1月-2021年10月就诊于该院的54例食管癌术后良性狭窄患者的临床资料,根据不同手术方法,将患者分为ERITA组(n=19)和内镜下探条扩张联合局部注射曲安奈德(EBDTA)组(n=35),比较两组治疗结果,并评估经治疗后狭窄复发和并发症发生情况。结果54例患者均顺利完成ERITA或EBDTA治疗。ERITA组中难治性食管狭窄患者占比更高,ERITA组的手术时间长于EBDTA组[(45.5±12.7)和(20.4±8.6)min],差异有统计学意义(P=0.032)。两组患者并发症总发生率比较,差异无统计学意义(P=0.527)。术后6个月随访,ERITA组术后狭窄复发中位时间明显长于EBDTA组(159.0和80.5 d,P=0.037),且ERITA组在治疗难治性食管狭窄患者方面疗效明显优于EBDTA组。结论ERITA治疗食管良性狭窄是安全有效的方法,在预防狭窄复发方面也具有较好的效果,未来可能成为一种治疗难治性食管良性狭窄患者的新的手段。

The precise control of the shape of transversely stiffened suspended cable systems is crucial. However, existing form-finding methods primarily rely on iterative calculations that treat loads as fixed known conditions. These methods are inefficient and fail to accurately control shape results. In this study, we propose a form-finding method that analyzes the load response of models under different sag and stress levels, taking into account the construction process. To analyze the system, a structural finite element model was established in ANSYS, and geometric nonlinear analysis was conducted using the Newton-Raphson method. The form-finding analysis results demonstrate that the proposed method achieves precise control of shape, with a maximum shape error ranging from 0.33% to 0.98%. Furthermore, the relationships between loads and tension forces are influenced by the deformed shape of the structures, exhibiting significant geometric nonlinear characteristics. Meanwhile, the load response analysis reveals that the stress level of the self-equilibrium state in the transversely stiffened suspended cable system is primarily governed by strength criteria, while shape is predominantly controlled by stiffness criteria. Importantly, by simulating the initial tensioning process as an initial condition, this method solves for a counterweight that satisfies the requirements and achieves a self-equilibrium state with the desired shape. The shape of the self-equilibrium state is precisely controlled by simulating the construction process. Overall, this work presents a new method for analyzing the form-finding process of large-span transversely stiffened suspended cable system, considering the construction process which was often overlooked in previous studies.

Chemical prelithiation is widely proven to be an effective strategy to address the low initial coulombic efficiency(ICE)of promising SiO_(x) *** the reagent composition has been widely explored,the Li^(+) solvation structure,which practically plays the cornerstone role in the prelithiation ability,rate,uniformility,has rarely been explored.A novel environmentally-friendly reagent with weak solvent cyclopentyl methyl ether(CPME)is proposed that enables both improved ICE and spatial homogeneous solid electrolyte interphase(SEl).And the prelithiation behavior and mechanism were explored focused on the Li^(+) solvation *** theoretical investigation and spectroscopic results suggest that weak solvent feature of CPME reduces the solvent coordination number and decreases the Li^(+) desolvation energy.

We have studied the high-pressure compression behavior of molybdenum up to 60 GPa by synchrotron radial x-ray diffraction(RXRD)in a diamond anvil cell(DAC).It is found that all diffraction peaks of molybdenum undergo a split at around 27 GPa,and we believe that a phase transition from a body-centered cubic structure to a rhombohedral structure at room pressure has *** slope of pressure–volume curve shows continuity before and after this phase transition,when fitting the pressure–volume curves of the body-centered cubic structure at low pressure and the rhombohedral structure at high pressure.A bulk modulus of 261.3(2.7)GPa and a first-order derivative of the bulk modulus of 4.15(0.14)are obtained by using the nonhydrostatic compression data at the angleψ=54.7°between the diffracting plane normal and stress axis.
