Objective To investigate the rehabilitative effect of low frequency repetitive transcranial magnetic stimulation (rTMS) on convalescing patients with Broca's aphasia. MethodsTwenty-eight patients with Broca's aphasia recovering from cerebral infarction were randomly divided into a stimulation group and a control group with 14 subjects in each.Patients in the control group accepted conventional drugs,speech rehabilitation and sham stimulation,while patients in the stimulation group were in given low frequency rTMS in place of the sham stimulation.Their speech performance was evaluated using the China Rehabilitation Research Center's aphasia examination (CRRCAE) pre-stimulation,post-stimulation and 90 days later. ResultsCompared with before treatment and with the controls,the speaking scores of the stimulation group increased significantly after treatment and also 90 days later. ConclusionLow frequency rTMS can not only improve the speech performance of Broca's aphasia sufferers in the short term,but it also plays a lasting role.It may thus have clinical application for patients with Broca's aphasia.

PURPOSE: Accumulating evidence suggests that microRNA-145 (miR-145) plays an important role in osteoarthritis (OA), which is a chronic progressive joint disease. Long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) promotes metastasis in cancers and functions as a sponge for miR-145. However, the role of MALAT1/miR-145 in OA pathogenesis has not yet been elucidated. MATERIALS AND METHODS: The expression of MALAT1 and miR-145 was examined by quantitative real-time PCR; the interaction between miR-145, MALAT1 and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 5 was verified by luciferase reporter assay. Correlations among MALAT1, miR-145, and ADAMTS5 were analyzed by Spearman rank analysis. Chondrocytes viability and cartilage extracellular matrix (ECM) degradation were investigated with cell viability assay and Western blotting analyzing expression of ADAMTS5, collagen type 2 alpha 1 (COL2A1), aggrecan (ACAN), and cartilage oligomeric matrix protein (COMP). RESULTS: MALAT1 was upregulated, and miR-145 was downregulated in OA samples and IL-1β-induced chondrocytes. Mechanically, miR-145 could directly bind to MALAT1 and ADAMTS5. Moreover, miR-145 expression was negatively correlated with MALAT1 and ADAMTS5 expression in OA patients, whereas MALAT1 and ADAMTS5 expression was positively correlated. Functionally, overexpression of MALAT1 inhibited chondrocyte viability and promoted cartilage ECM degradation in IL-1β-induced chondrocytes. In support thereof, MALAT1 silencing and miR-145 upregulation exerted the opposite effect in IL-1β-induced chondrocytes. Moreover, the effect of MALAT1 was counteracted by miR-145 upregulation, and ADAMTS5 restoration could abate miR-145 effects. CONCLUSION: An MALAT1/miR-145 axis contributes to ECM degradation in IL-1β-induced chondrocytes through targeting ADAMTS5, suggesting that MALAT1/miR-145/ADAMTS5 signaling may underlie human OA pathogenesis.

OBJECTIVE: To explore the clinical characteristics and genetic basis of a child with Kartagener syndrome (KTS). METHODS: Trio-whole exome sequencing was carried out for the child and his parents, and candidate variants were verified by Sanger sequencing. Changes in protein structure due to missense variants were simulated and analyzed, and the Human Splicing Finder 3.0 (HSF 3.0) online platform was used to predict the effect of the variant of the non-coding region. RESULTS: The child had featured bronchiectasis, sinusitis and visceral inversion. Genetic testing revealed that he has harbored compound heterozygous variants of the DNAH5 gene, namely c.5174T>C and c.7610-3T>G. Sanger sequencing confirmed the existence of the variants. The variants were not found in the dbSNP, 1000 Genomes, ExAC, ClinVar and HGMD databases. Protein structural analysis suggested that the c.5174T>C (p.Leu1725Pro) variant may affect the stability of local structure and its biological activity. The results of HSF 3.0 analysis suggested that the c.7610-3T>G variant has probably destroyed a splicing receptor to affect the transcription process. CONCLUSION The compound heterozygous variants of the DNAH5 gene probably underlay the pathogenesis in the child. Above finding may facilitate the understanding of the clinical characteristics and genetic basis of KTS, and further expand the spectrum of DNAH5 gene variants.

China is a country with a high incidence of esophageal cancer.The pathological type is mainly squamous cell carcinoma.Squamous intraepithelial neoplasia is the most recognized precancerous lesion of esopha-geal squamous cell carcinoma,and its monitoring and intervention is an effective method to reduce the incidence of esophageal squamous cell carcinoma and improve the quality of life of patients.Understanding the etiology,clinical features,diagnosis and treatment of esophageal squamous cell carcinoma plays a crucial role in the prevention and early diagnosis and treatment of esophageal squamous cell carcinoma.At present,the clinical research related to esophageal squamous intraepithelial neoplasia is still insufficient,and there are some differences in clinical treat-ment.This review summarizes the risk factors,clinical features,diagnosis,prognosis and treatment of esophageal squamous intraepithelial neoplasia,hoping to provide ideas for the clinical management of esophageal squamous intraepithelial neoplasia.
