Young stroke patients have a strong desire to return to the society, but few studies have been conducted on their rehabilitation training items, intensity, and prognosis. We analyzed clinical data of young and middle-aged/older stroke patients hospitalized in the Department of Neurological Rehabilitation, China Rehabilitation Research Center, Capital Medical University, China from February 2014 to May 2015. Results demonstrated that hemorrhagic stroke （59.6%） was the primary stroke type found in the young group, while ischemic stroke （60.0%） was the main type detected in the middle-aged/older group. Compared with older stroke patients, education level and incidence of hyperhomocysteinemia were higher in younger stroke patients, whereas, incidences of hypertension, diabetes, and heart disease were lower. The average length of hospital stay was longer in the young group than in the middle-aged/older group. The main risk factors observed in the young stroke patients were hypertension, drinking, smoking, hyperlipidemia, hyperhomocysteinemia, diabetes, previous history of stroke, and heart disease. The most accepted rehabilitation program consisted of physiotherapy, occupational therapy, speech therapy, acupuncture and moxibustion. Average rehabilitation training time was 2.5 hours/day. Barthel Index and modified Rankin Scale scores were increased at discharge. Six months after discharge, the degree of occupational and economic satisfaction declined, and there were no changes in family life satisfaction. The degrees of other life satisfaction （such as friendship） improved. The degree of disability and functional status improved significantly in young stroke patients after professional rehabilitation, but the number of patients who returned to society within 6 months after stroke was still small.

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

ZiO2 was prepared by the hydrolyzation method in （NH4）2SO4-modified TiCl4 solution, and TiO2 photocatalysts were obtained by accelerating the precipitation of TiO2 powder in a high-temperature water bath. The photocatalysts were characterized by Brunauer-Emmett-Teller （BET）, X-ray diffraction （XRD）, Raman spectrum and UV-Vis （Ultraviolet-Visible） spectrometry techniques, and the photocatalytic activity in phenol-contaminated water was investigated. The results showed that photocatalysts calcined at 400 ℃ had a specific surface area of 138.2 m^2/g and an average particle size of 9 nm, and a significant increase in thermal stability of anatase phase. At the calcination temperature of 700 ~C, the crystal form of TiO2 started to change into rutile （anatase： 97%, rutile： 3%）. The activity of TiO2 photocatalysts prepared with （NH4）2SO4-modified TIC14 solution was markedly stronger than that without （NH4）2SOg-modified TIC14 solution. Maximal photocatalytic activity was observed at the mole ratio of Ti：（NH4）2SO4= 1：2, the water-bath temperature of 90℃ and the calcination temperature of 700 ℃.

Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resulting in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOL） compatibility.

ON HERMITIAN POSITIVE DEFINITE SOLUTION OF NONLINEAR MATRIX EQUATION X＋A^＊X^-2A=Q

引用

Journal of Computational Mathematics 2005年第5期23卷 513-526页

作者： xiao xia Guo ICMSEC Academy of Mathematics and System Sciences Chinese Academy of Sciences Beijing 100080 China

Based on the fixed-point theory, we study the existence and the uniqueness of the maximal Hermitian positive definite solution of the nonlinear matrix equation X＋A^＊X^-2A=Q, where Q is a square Hermitian positive definite matrix and A＊ is the conjugate transpose of the matrix A. We also demonstrate some essential properties and analyze the sensitivity of this solution. In addition, we derive computable error bounds about the approximations to the maximal Hermitian positive definite solution of the nonlinear matrix equation X＋A^＊X^-2A=Q. At last, we further generalize these results to the nonlinear matrix equation X＋A^＊X^-nA=Q, where n≥2 is a given positive integer.

OBJECTIVE: To evaluate the effectiveness and safety of moxibustion therapy in the treatment of lumbar disc herniation (LDH). METHODS: Four Chinese databases and three English databases were searched from their inception to April *** controlled trials (RCTs) were included if moxibustion was used as the sole treatment or as a part of combination therapy with other treatments in patients with LDH. Two reviewers independently extracted the data and assessed the methodological quality using the Cochrane criteria for the risk of bias. The Meta-analysis was performed using Review Manager 5.3 software. RESULTS: In total, 16 RCTs including 1186 patients with LDH were analyzed. The Meta-analysis showed favorable effects of moxibustion in combination with massage therapy on the visual analog scale score compared with massage therapy alone [mean difference (MD)=? 1.32, 95% confidence interval (CI)(? 2.12,? 0.51), P = 0.001]. The subgroup Meta-analysis failed to show favorable effects of electro-acupuncture plus moxibustion on the efficacy rate compared with electro-acupuncture alone [relative risk (RR)= 1.06, 95% CI (0.98, 1.14), P = 0.15]. However, acupuncture or massage therapy plus moxibustion improved the efficacy rates compared with acupuncture or massage therapy alone [RR = 1.33, 95% CI (1.18, 1.49), P duced results different from those of acupuncture or massage therapy alone [MD = 5.58, 95% CI (4.15, 7.00), P during moxibustion.

Magnetic field induced synthesis of(Ni, Zn)Fe2O4 spinel nanorod for enhanced alkaline hydrogen evolution reaction

引用

Progress in Natural Science:Materials International 2023年第2期33卷 172-177页

作者： Mingkun xia Yan zhang Jiangyue xiao Peng Zhao Zhongjun Hou Fanglin du Dawei Chen Shuo Dou College of Material Science and Engineering Qingdao University of Science and Technology Key Laboratory of Bio-Based Material Science and Technology of Ministry of Education Northeast Forestry University

Recently, the introduction of external fields(light, thermal, magnetism, etc.) during electrocatalysis reactions gradually becomes a new strategy to modulate the catalytic activities. In this work, an external magnetic field was innovatively employed for the synthesis progress of(Ni, Zn)Fe2O4spinel oxide(M-(Ni, Zn)Fe2O4). Results indicated the magnetic field(≤250 m T) would affect the morphology of catalyst due to the existing Fe ions, inducing the M-(Ni, Zn)Fe2O4nanosphere particles to be uniform and coral-like nanorods. In addition, the electronic structure of the catalyst was regulated by the valence state of Fe, changing the bonding of metal to oxygen atoms in different spinel sites. The results manifested that the M-(Ni, Zn)Fe2O4requires a lower overpotential of only 67m V to deliver 10 m A cm-2for hydrogen evolution reaction(HER) in alkaline electrolyte. Moreover, M-(Ni, Zn)Fe2O4respectively as the anode and cathode electrode for the overall water splitting, the catalysis system requires a cell voltage of only 1.76 V to gain a current density of 50 m A cm-2, combining with an excellent discharging stability after 10 h. This work provides a facile synthesis strategy toward the design of efficient non-noble metal catalysts for alkaline HER and overall water splitting.
