Objective To investigate the role of autophagy and synaptophysin (SYP) in cognitive impairment in de?pressed rats receiving electroconvulsive shock (ECS). Methods Clean and healthy adult male Sprague-Dawley rats were acclimatized to a standard laboratory environment for 7 days. The chronic unpredictable mild stress (CUMS) was used to establish the rat model of depression. Behavior tests were conducted before and after CUMS to evaluate the depression and cognition level of rats. After establishment of the model, 24 rats were randomly divided into ESC group (group E) and depression group (group D) with 12 rats in each group. The rats in group E were administered 80 mg/kg of propofol (10 mg/mL) by intraperitoneal injection, followed by ECS treatment. The rats in group D were administered propofol by intra?peritoneal injection, followed by sham-ECS treatments. The above interventions were conducted daily for 7 consecutive days. After the interventions, rats underwent behavior tests as before. Subsequently, rats were killed and specimens were collected for measurements. Immunohistochemistry was performed to examine autophagy markers such as Beclin 1 and LC3Ⅱand ELISA was used to detect SYP in the hippocampus. Results Group E after ECS significantly increased the percentage of sucrose preference (68.2%±8.7%), rearing times (7.0±1.9), total horizontal distance [(569.5±70.0) cm], es? cape latency [(21.9±5.3)s] and space exploration time [(20.5±3.9)s] compared with group D or group E before ECS. There was no significant difference in these index between groups before ECS or in group E between before and after ECS(P>0.05). Compared with group D, group E had upregulated protein expression levels of Beclin 1 and LC3Ⅱin CA1, CA3, DG as well as the area near the hippocampus and increased SYP contents (P<0.05). Conclusions Cognitive impairment in depression rats following ECS correlates with activated autophagy and increased SYP by ECS.

AIM: To optimize the conditions for in vitro culture of retinal pigment epithelium (RPE) cells, we characterized expressions of various growth factors in RPE cells, including tumor necrosis factor (TNF-α), vascular endothelial growth factor (VEGF), β fibroblast growth factor (βFGF), transforming growth factor β2 (TGFβ2), and interferon-γ (IFN-γ). We also studied expressions of caspase-3 under different concentrations of fetal bovine serum (FBS) with insulin-transferrin-sodium selenite (ITS) supplement. METHODS: First, we investigated if expressions of TNF-α, VEGF, βFGF, TGFβ2, IFN-γ, and caspase-3 in FBS and ITS with of concentration. Second, we cultured primary RPE cells from eyes of forty C57 BL/6 mice in standard dulbecco's modified eagle's medium (DMEM) containing 20,40,100mL/L FBS and 20,40,100mL/L FBS together with 10g/L ITS. Immunohisto-chemical staining and cell counting were performed to verify the existence and growth condition of RPE cells. Expressions of TNF-α, VEGF, βFGF, TGFβ2 and IFN-γ were determined using cells and supernatant from passage-3 to -4 primary RPE cell after 48 hours of culture with RT-PCR and enzyme-linked immunosorbent assays (ELISA). The expression of casepase-3 was determined via Western blotting. The major outcome measurement is the expression level of growth factors in cultured RPE cells and the experiment design is to expose the RPE cells to different culture medium. RESULTS: TNF-α, VEGF, βFGF, TGFβ2, but not IFN-γ, were expressed and the expressions increased with concentration. No expression of the aforementioned genes was detected in presence of ITS. The primary cultures of RPE cells were successfully established. TNF-α, VEGF, βFGF, TGFβ2 (but no IFN-γ) and the active caspase-3 were detected in 20,40,100mL/L FBS or 20,40,100mL/L FBS combined with 10g/L ITS; the expressions were upregulated with increasing concentration of FBS. There is no significant difference in the expression of growth factors between these groups. However, significant differences were shown among different concentration of FBS (P<0.01). The lowest expression was observed in 20mL/L FBS or 20mL/L FBS combined with 10g/L ITS medium with RPE cells. But RPE cells were shown in better growth condition in 20mL/L FBS combined with 10g/L ITS.CONCLUSION: TNF-α, VEGF, βFGF, TGFβ2 and caspase-3 were expressed in RPE cells and supernatants. The production of above 20mL/L FBS combined with 10g/L ITS in DMEM may be the ideal cell culture medium that supports the normal growth of RPE cells.
