Subsequently, 0.3, 3, and 10 nmol/L recombinant human FST (rhFST) were used to stimulate hBMSCs, respectively. Neuron-like cell differentiation and Nissl's body within the cytoplasm of hBMSCs were investigated by a transmission electron microscope (TEM). Meanwhile, nestin and NSE were determined by immunofluorescence. The expression level of Activin A, BMP4, Moysatin, and Smad3 were detected by Western blotting. RESULTS The isolated hBMSCs were positive for CD29, CD44, and CD166, but negative for CD34, CD14, and CD45. The level of nestin and NSE mRNAs were significantly higher than those before induction (both P less then 0.05). Additionally, immunofluorescence revealed that nestin and NSE positive cells significantly increased as the rhFST concentration increased. With the increase of rhFST concentration, the expression level of Activin A gradually decreased accordingly, but the expression levels of BMP4 and Moysatin did not change significantly. Furthermore, the expression level of Smad3 gradually decreased with the increase of rhFST concentration. CONCLUSIONS Our study indicates that FST could effectively induce hBMSCs to differentiate into neuron-like cells in vitro. This differentiation mechanism may be related to the Activin A signalling pathway, partially through binding to Activin receptors and inhibiting expression of Smad3. © 2020 by the Association of Clinical Scientists, Inc.PURPOSE To assess the incidence, clinical features and predictive risk factors of subretinal fibrosis after treatment of active myopic choroidal neovascularisation (mCNV) with anti-vascular endothelial growth factor (VEGF). METHODS This post-hoc analysis of a randomised controlled trial included a total of 54 patients with active mCNV. The clinical data at baseline, month 3 and month 12 were used. Fundus photography and optical coherence tomography at month 3 were used to determine the presence of subretinal fibrosis after anti-VEGF therapy, and its incidence was calculated. Best-corrected visual acuity (BCVA), Visual Function Questionnaire-25 score, macular integrity index (MI) and their changes were compared between eyes with and without subretinal fibrosis. A logistic regression model was used to evaluate the risk factors of subretinal fibrosis. RESULTS Subretinal fibrosis occurred in 22 of 54 eyes with mCNV. Patients with subretinal fibrosis achieved similar BCVA improvement in comparison with those without fibrosis at 3 and 12 months after the treatment; however, they had lower visual acuity, more subfoveal CNV (p=0.002), higher CNV thickness at baseline (p=0.016), larger CNV size (p=0.030), larger leakage area (p=0.021) and higher presence of advanced myopic maculopathy (p=0.035). Age less then 45 years, BCVA less then 60 ETDRS letters, and MI index less then 20 at baseline were the predictors for subretinal fibrosis occurrence in a logistic regression model. CONCLUSIONS The incidence of subretinal fibrosis after anti-VEGF therapy was 40.7% in eyes with mCNV. Age, baseline BCVA and MI index could serve as predictive risk factors of subretinal fibrosis after anti-VEGF treatment in patients with mCNV. © Author(s) (or their employer(s)) 2020.

METHODS We reviewed baseline examinations of patients with neovascular age-related macular degeneration using multimodal imaging. We determined the type and distribution of MNV lesions in each cMNV3 case, the range of distances from the fovea, existence of exudative maculopathy, intraretinal haemorrhage and other morphological characteristics. 50 consecutive eyes with usual MNV3 without CRA were included as a control group. RESULTS 102 eyes of 102 patients were identified with MNV3 lesions. Among these, we found 12 eyes (12%) with cMNV3, 84 eyes (82%) with usual MNV3 without CRA and 6 eyes (6%) with usual MNV3 with CRA. Ten cases of cMNV3 had one lesion, and two cases had two lesions. The lesions were distributed equally between the superior and inferior halves of the macula, whereas in the nasal and temporal halves, there were 8 (57%) and 6 (43%) lesions, respectively. All cMNV3 lesions were located between 500 and 1500 µm from the central fovea except one, which was located between 1500 and 3000 µm. None of the lesions had macular neovascularisation type I (MNV1) or macular neovascularisation type II (MNV2) elsewhere in both groups. Exudative maculopathy and intraretinal haemorrhage were found in seven (88%) and five (63%) of the eight pure cMNV3 cases, respectively. CONCLUSION cMNV3 can be solitary or multiple, isolated or accompanied with usual MNV3 lesions, but not with concurrent MNV1 or MNV2. It is frequently associated with extensive exudative maculopathy, intraretinal haemorrhage and subretinal fluid. © Author(s) (or their employer(s)) 2020. No commercial re-use.

Our objectives were to determine the prevalence of isolated BP load elevation and associated risk with adverse outcomes in children with CKD, and to ascertain whether BP load offers risk discrimination independently or in conjunction with mean ambulatory BPs. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We studied 533 children in the CKD in Children (CKiD) Study to determine the prevalence of normotension, isolated BP load elevation (≥25% of all readings elevated but mean BP normal), and ambulatory hypertension. We examined the association between these categories of BP control and adverse outcomes (left ventricular hypertrophy [LVH] or ESKD). We used c-statistics to determine risk discrimination for outcomes by BP load used either independently or in conjunction with other BP parameters. RESULTS Overall, 23% of the cohort had isolated BP load elevation, but isolated BP load elevation was not statistically significantly associated with LVH in cross-section (odds ratio, 1.
