Context: TECPR2 was first described as a disease causing gene when the c.3416delT frameshift mutation was found in five Jewish Bukharian patients with similar features. It was suggested to constitute a new subtype of complex hereditary spastic paraparesis (SPG49).', 'We report here 3 additional patients from unrelated non-Bukharian families, harboring two novel mutations (c.1319delT, c.C566T) in this gene. Accumulating clinical data clarifies that in addition to intellectual disability and evolving spasticity the main disabling feature of this unique disorder is autonomic-sensory neuropathy accompanied by chronic respiratory disease and paroxysmal autonomic events.
Answer: We suggest that the disease should therefore be classified as a new subtype of hereditary sensory-autonomic neuropathy. The discovery of additional mutations in non-Bukharian patients implies that this disease might be more common than previously appreciated and should therefore be considered in undiagnosed cases of intellectual disability with autonomic features and respiratory symptoms regardless of demographic origin.
Do tECPR2 mutations cause a new subtype of familial dysautonomia like hereditary sensory autonomic neuropathy with intellectual disability?

Context: Cirrhosis, or liver fibrosis, which is mainly triggered by cirrhosis fat-storing cells (CFSCs) activation, has traditionally been considered an irreversible disease. However, recent observations indicate that even advanced fibrosis is still reversible by removing the causative agents. Anti-fibrotic effects of bone marrow-derived stromal cells (BMSCs) have been demonstrated by inhibiting CFSCs via cytokines secretion; however, the mechanisms are still unclear.', 'The purpose of this study was to explore the underlying mechanisms by which BMSCs modulate the function of activated CFSCs.', 'After the co-culture of CFSCs with BMSCs supernatants with or without the addition of recombinant rat adrenomedullin (AM)/AM-specific siRNA, western blot analysis was mainly used to detect the differences of relative protein expression on CFSCs.', 'BMSC-secreted adrenomedullin (AM) effectively inhibited the proliferation and activation of CFSCs by suppressing the expression of Ang II and its binding receptor, AT1, which resulted in a reduction of p47-phox formation.
Answer: Our data suggested that BMSCs inhibited CFSC activation in vitro via the AM-Ang II-p47-phox signaling pathway, and since CFSC activation is an essential part of hepatic fibrosis process, this inhibition by BMSCs implies us new insights into the potential treatment of hepatic fibrosis via BMSCs.

Context: The prognostic importance of red cell distribution width (RDW) and neutrophil/lymphocyte ratio (NLR) in cardiovascular diseases has been shown. Ascending aortic dilatation (AAD) is a common cardiovascular disease and is associated with aortic wall inflammation and cystic degeneration. In this study, we aimed to investigate the relationship between serum levels of RDW, NLR and the presence of AAD.', 'Two-hundred consecutive patients with AAD diagnosed by transthoracic echocardiography were prospectively recruited and were compared to 170 age-gender- matched subjects with normal aortic diameters. Complete blood counts (CBCs) were analyzed for hemoglobin, RDW and NLR counts, as well as mean corpuscular volume (MCV). If possible, results of CBC tests within the previous two years were also included and the averages were used.', 'RDW [median 13.9, interquartile range (IQR) 1.40 vs. median 13.3, IQR 1.05%, p=0.01], NLR (median 2.04, IQR 1.09 vs. median 1.78, IQR 0.90, p=0.01) and high-sensitive C-reactive protein (hs-CRP) (median 0.60, IQR 0.80 vs. median 0.44, IQR 0.68 mg/L, p=0.01) levels were significantly higher in the AAD group compared to the control group. In univariate correlation analysis, ascending aortic diameters were correlated with RDW levels (r=0.31, p=0.01), NLR levels (r=0.15, p=0.01) and hs-CRP levels (r=0.12, p=0.03). In multivariate logistic regression analysis, increased levels of RDW and hs-CRP remained as the independent correlates of AAD in the study population. Receiver operating characteristic (ROC) curve analysis revealed that a RDW measurement higher than >13.8% predicted AAD with a sensitivity of 49.5% and a specificity of 82.8% (area under the curve [AUC] 0.681, p=0.01).
Answer: In patients with AAD, RDW and hs-CRP levels are increased, which may indicate the role of inflammation in the pathogenesis of AAD.
