Animal and clinical studies have confirmed the therapeutic effect of bone marrow mesenchymal stem cells on cerebral ischemia, but their mechanisms of action remain poorly understood. Here, we summarize the transplantation approaches, directional migration, differentiation, replacement, neural circuit reconstruction, angiogenesis, neurotrophic factor(More)
OBJECTIVES Glioblastoma multiforme (GBM) is the most aggressive brain tumour type in humans. Its poor prognosis is largely attributed to its invasiveness and high rate of recurrence. Recurring GBM is commonly resistant to chemotherapeutic drugs, making it specially difficult to treat. Recent studies have revealed that matricellular glycoprotein SPOCK1 to be(More)
OBJECTIVE A potential association between diabetes and Guillain-Barré syndrome (GBS) has been indicated by a few case studies. We retrospectively analyzed the clinical features of a large cohort of GBS patients to explore the relationship between the level of fasting plasma glucose (FPG) obtained in the acute phase at admission and the severity of GBS.

This paper combines quantum evolutionary algorithm with the available evolutionary algorithms, uses quantum computing parallelism to search solution space efficiently, uses the traditional evolutionary algorithm to optimize the result observed by quantum population and then uses the optimized result to guide the generation of some individuals of quantum(More)
BACKGROUND Selective tibial neurotomy (STN) was considered as an effective procedure for the treatment of spastic feet. It is also widely used for treating obese calves in some Asian countries. This study aimed to provide morphologic measurement data and theoretical support for the operation and intraoperative localization. METHODS Fifty lower legs from(More)
The aim of this study was to report a rare case of Aspergillus fumigatus infection complicated with cavernous hemangioma in the central nervous system of a patient with normal immune function and to investigate its causes. A 60-year-old male patient was admitted three years ago due to meningioma-induced convulsions. In addition to meningioma, magnetic(More)
The traditional channel estimation based on Discrete Fourier Transform (DFT) for Orthogonal Frequency Division Multiplexing (OFDM) system has significantly outperformed least square (LS) or minimum mean-square error (MMSE) channel estimation by eliminating the impact of noise beyond the maximum channel delay. However, its performance is degraded due to the(More)
An improved adaptive filtering (IMPNLMS+) algorithm has been proposed for non-sparse impulse responses by incorporating an adaptive parameter μ of the μ-law compression into the improved μ-law PNLMS algorithm (IMPNLMS) algorithm. It not only achieves optimal step-size control factors but also overcomes that the convergence of classical μ-law PNLMS (MPNLMS)(More)
