ABSTRACT
ObjectiveTo evaluate the effects of transcranial direct current stimulation (tDCS) on post-stroke aphasia (PSA). MethodsLiteratures about tDCS for PSA were retrieved from PubMed, Web of Science, Cochrane library, Embase CNKI and Wanfang Data, until December, 2021. The contents of the author, publication time, subjects, intervention methods and time, main outcome indicators and conclusions were extracted. ResultsA total of 1 026 articles were returned and 45 articles were finally included. The publication time was from 2010 to 2021. The subjects of the study were patients with PSA. The main outcome indicators were the various speech scales and their sub-items. For most of the trials, scores of the scales were better in the experimental groups than in the control groups after treatment, and a few found little improvement in Boston Diagnostic Aphasia Examination, or only improved in complex language tasks. tDCS can improve the repetition, naming, spelling and verbal fluency of PSA patients, which might relate with electrode placement, current magnitude, duration, intensity and left cortical integrity. ConclusiontDCS is effective on different language sub-items of PSA, and various with the program of tDCS.
ABSTRACT
Background@#African swine fever virus (ASFV), classical swine fever virus (CSFV), and porcine reproductive and respiratory syndrome virus (PRRSV) are still prevalent in many regions of China. Co-infections make it difficult to distinguish their clinical symptoms and pathological changes. Therefore, a rapid and specific method is needed for the differential detection of these pathogens. @*Objectives@#The aim of this study was to develop a multiplex real-time quantitative reverse transcription polymerase chain reaction (multiplex qRT-PCR) for the simultaneous differential detection of ASFV, CSFV, and PRRSV. @*Methods@#Three pairs of primers and TaqMan probes targeting the ASFV p72 gene, CSFV 5′untranslated region, and PRRSV ORF7 gene were designed. After optimizing the reaction conditions, including the annealing temperature, primer concentration, and probe concentration, multiplex qRT-PCR for simultaneous and differential detection of ASFV, CSFV, and PRRSV was developed. Subsequently, 1,143 clinical samples were detected to verify the practicality of the assay. @*Results@#The multiplex qRT-PCR assay could specifically and simultaneously detect the ASFV, CSFV, and PRRSV with a detection limit of 1.78 × 10 0 copies for the ASFV, CSFV, and PRRSV, but could not amplify the other major porcine viruses, such as pseudorabies virus, porcine circovirus type 1 (PCV1), PCV2, PCV3, foot-and-mouth disease virus, porcine parvovirus, atypical porcine pestivirus, and Senecavirus A. The assay had good repeatability with coefficients of variation of intra- and inter-assay of less than 1.2%. Finally, the assay was used to detect 1,143 clinical samples to evaluate its practicality in the field. The positive rates of ASFV, CSFV, and PRRSV were 25.63%, 9.36%, and 17.50%, respectively. The co-infection rates of ASFV+CSFV, ASFV+PRRSV, CSFV+PRRSV, and ASFV+CSFV+PRRSV were 2.45%, 2.36%, 1.57%, and 0.17%, respectively. @*Conclusions@#The multiplex qRT-PCR developed in this study could provide a rapid, sensitive, specific diagnostic tool for the simultaneous and differential detection of ASFV, CSFV, and PRRSV.
ABSTRACT
Authors of the paper analyzed the motivation of building the healthy town,and interrelated the scientific aspects of such a town. It was found that this town of diversified resources and advantages had become small but beautiful,special and strong clustering and convergent by means of collecting high-end factors, selecting of essential health businesses and constructing an ecosystem of health industry clusters. Based on a definition of the government role,the paper described the innovation of health policy in view of policy supply.
