Objective:To investigate the role and mechanism of miR-143 in the proliferation and migration of gastric cancer (GC) cells. Methods:Western blot was performed to detect the expression level of avian erythroblastosis oncogene B-3 (ERBB3) in GC tissues, paired non-cancerous tissues, and SGC7901 GC cells. RT-qPCR was conducted to determine the mRNA and miR-143 of ERBB3 quantita-tively. Bioinformatics tools were used to predict the target gene of miR-143. Luciferase reporter assay was carried out to confirm the predicted target gene. Transwell and EdU assays were applied to observe the migration and proliferation of SGC7901 GC cells transfect-ed with miR-143 mimics/inhibitor/NC mimics/inhibitor. Results:Compared with the expression levels of ERBB3 and miR-143 in the paired non-cancerous tissues, the expression level of ERBB3 was upregulated and the expression level of miR-143 was downregulated in GC tissues. In the prediction of the potential target gene, miR-143 could bind to a specific sequence of the 3′-untranslated regions (UTR) of the mRNA of ERBB3. This finding was supported by luciferase reporter assay results. In vitro, ERBB3 protein expression and cell migration and proliferation were suppressed significantly in the SGC7901 cells transfected with miR-143 mimics. By contrast, these processes were remarkably enhanced when the cells were transfected with miR-143 inhibitor. Conclusion:miR-143 can suppress the migration and proliferation of GC cells by downregulating the expression of ERBB3.

Objective To analyze the risk factors of cerebral microbleeds (CMBs) in acute cerebral infarction patients. Methods We consecutively included 255 acute cerebral infarction patients who were admitted in Neurology Department of the First Affiliated Hospital of Fujian Medical University from January 2014 to December 2016. According to the number and location of CMBs, the patients were divided into infratentorial, cortical and deep cerebral groups, each of which included non-mild and moderate-severe subgroups. The differences of the level of glomerular filtration rate (eGFR) and some common arteriosclerotic risk factors were analyzed between subgroups, and the multiple logistic regression analysis was performed. Results A total of 140 subjects (54.9%) had CMBs. In the infratentorial group, the proportion of patients who were with low eGFR level in the moderate-severe CMBs subgroup was higher than in the non-mild CMBs subgroup (P=0.024). The low eGFR level (OR=3.874, 95% CI:1.261~11.901, P=0.018) and the long duration of hypertension (OR=2.128, 95%CI: 1.004~4.510, P=0.018) were the independent risk factors of the moderate-severe infratentorial CMBs. Conclusion The low eGFR level and long duration of hypertension are risk factors for the moderate and severe infratentorial CMBs after acute ischemic stroke.

【Objective】 To investigate changes in thalamus structure and function and their associations with cognitive impairment in patients with amyotrophic lateral sclerosis (ALS). 【Methods】 3D high-resolution structural imaging and resting-state fMRI were applied in 78 ALS patients and 49 healthy volunteers. The shape of the thalamus was assessed using a vortex analysis and functional connectivity between the thalamus subregion and cortex was evaluated by a seed-based correlation analysis. Partial correlation analysis was used to evaluate the correlation between focal thalamus alterations and clinical assessments. 【Results】 Compared with the control group, vertex analysis showed significant atrophy in the prefrontal and temporal subregions of bilateral thalamus in the ALS group. Patients exhibited increased functional connectivity of motor-sensory ROI with the right motor cortex, of temporal ROI with the bilateral lateral occipital cortex, precuneus and right temporal subregion. In contrast, decreased function connectivity was found mainly between temporal ROI and paracingulate gyrus, left dorsomedial prefrontal lobe and left caudate. Partial correlation analysis showed that the functional connectivity of the precuneus, paracingulate cortex, left caudate nucleus and left prefrontal lobe was correlated with multiple cognitive performances. 【Conclusion】 Selective damage of thalamic structure and function in ALS plays an important role in cognitive and behavioral disorders.
