Background The light damage model of retinal pigment epithelium (RPE) cells is a research direction of retinal degeneration diseases,and RPE cell apoptosis induced by light damage and inflammation is an important pathologic basis of light-induced RPE cell damage.However,whether endoplasmic reticulum stress (ERS) paticipates in light-induced RPE cell damage is rarely reported.Objective This study was to explore the effects of ERS on light-induced RPE cell damage.Methods Human RPE cell line (ARPE-19) was cuhured,and light damage models were created by irradiating the cells for 3-,6-,12-and 24-hours with white fluorescent lamp with the intensity of (2 000±500)lx for the selection of optimal irradiating time,and the cells in the normal control group were cultured in the dark environment.The cells were divided into normal control group,light exposure group and 4-phenylb utyric acid (4-PBA) pretreated +light exposure group.The cells from 4-PBA pretreated +light exposure group were cultued firstly with 4-PBA for 30 minutes and followed by light exposure for 12 hours.The apoptisis rate of the cells and intracellular reactive oxygen species (ROS) content were detected by flow cytometry;the concentrations of interleukin 1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the cell supernatant were assyed by ELISA.The relative expressing levels of activating transcription factor 6 (ATF-6),C/enhancer binding protein homologous protein (CHOP) and caspase-12 mRNA and protein in the cells were detected by real-time quantitative PCR and Western blot,respectively.Results The cultured cells showed a long spindle shape,the border was not clear,the cytoplasm was degranulation,and the cell fragments increased.Flow cytometry showed that compared with the normal control group,the ROS content in the cells and the apoptosis rate were evidently increased with the lapse of light exposure time (F=763.00,119.30,both at P＜0.01).ELISA results showed that the concentrations of IL-1β and TNF-α in the cell supernatant were significantly higher in the light exposure 6-hour group than those in the normal control group with the peak value in the light exposure 12-hour group.Compared with the normal control group,the relative expression levels of ATF-6,CHOP and caspase-12 mRNA and protein in the cells were elevated in the light exposure group and peaked in the light exposure 12-hour group.In addition,the relative expression levels of ATF-6 mRNA,CHOP mRNA and caspase-12 mRNA in the cells were significantly reduced in 4-PBA pretreated+light exposure group compared with the light exposure group (F=281.69,473.88,308.45,all at P＜0.01),and their proteins were also significantly reduced (F =47.86,57.93,106.59,all at P ＜ 0.01).The apoptosis rate,concentrations of IL-1β and TNF-α in the cell supernatant were significantly reduced in 4-PBA pretreated+light exposure group compared with the light exposure group (F =88.64,245.47,101.01,all at P＜0.01).Conclusions The light exposure at (2 000 ± 500)lx induces intracellular ROS accumulation and activates the ERS response,which results in apoptosis and inflammatory process of human RPE cells.4-PBA,a inhibitor of ERS,can suppress light-induced ERS response and therefore reduces the apoptosis rate and inhibits inflammatory process.

AIM: To explore the immunity modulation function of aqueous of Forsythia suspense (AFS) and its possible mechanisms. METHODS: Rats of burned model group were burned with vapor under 3mpa pressure and 108℃ temperature for 8 seconds to achieve deep partialthickness bum, to make a thirty percent total body surface area (TBSA)bum. The experiment were divided into five groups: Control group: without any treatment; 8 PBH group: 8 h after burn; the rats of AFS1 guoup, AFS2 group and AFS3 group of them were given AFS 5 g/kg, 2.5 g/kg, 1.25 g/kg once a day by Po. pathway for seven days before burns, respectively. Rats were sacrificed before and 8h after burn, The percentage of Treg cells in CD4~+ T cells was detected by flow cytometry(FCM) ; the expression of Foxp3 mRNA on splenocytes were measured by RT-PCR, and the protein of Foxp3 activity was evaluated by immunohistochemistry staining. RESULTS: Compared with Control group, the expression of Foxp3mRNA and protein on the splenocytes were upregulated markedly(P <0.01), and the percentage of Treg were significantly increased (P < 0.01) in the 8PBH group. AFS1, AFS2 and AFS3 significantly attenuated these increases (P < 0.01), which was dose-dependent. CONCLUSION: AFS has immunity modulation function and mechanism of it is corrected with Foxp3 mRNA on splenocytes.

Objective To understnad the defense mechanisms of patients with borderline personality disorder (BPD) and to explore its relationship with childhood abuses.Methods One hundred and forty-two outpatients with BPD (group A),63 outpatients with other personality disorders (group B) and 20 outpatients without any Axis Ⅱ diagnoses (group C) were enrolled and completed Chinese versions of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q) and the Defensive Style of Questionnaire (DSQ).Multivariate analysis of variance and Pearson correlation analysis were used for data analysis.Results Compared to group B and C,the score of defense mechanisms reported by group A were significantly increased in all eight premature defense mechanisms,such as projection(F =26.5,P ＜ 0.05),passive aggression (F =18.1,P ＜ 0.05),acting out (F =28.3,P ＜ 0.05),complaint (F =16.7,P ＜0.05),fantasy(F =16.3,P ＜ 0.05),splitting (F =28.8,P ＜ 0.05),withdrawal (F =8.3,P ＜ 0.05),somatization(F=7.6,P ＜ 0.05),and part of the middle defense mechanisms,such as omnipotence-devaluation(F =9.2,P ＜ 0.05),isolation(F =4.7,P ＜ 0.05) and identification (F =10.0,P ＜ 0.05).At the same time,the BPD patients got lower scores in the mature defense mechanisms,such as sublimation (F =4.1,P ＜ 0.05) and repression(F =3.9,P ＜ 0.05).Those who experienced physical abuse use more complaint (F =6.9,P ＜ 0.05),denial mechanisms (F =5.2,P ＜ 0.05) and less anticipation one (F =4.6,P ＜ 0.05).Those who experienced sexual abuse use more somatization (F =4.4,P ＜ 0.05) and isolation mechanism (F =3.6,P ＜ 0.05).Conclusions BPD patients would like to use more immature and middle defense mechanisms and less mature ones.Emotional,physical and sexual abuse from parents and other adult care takers have a correlation with immature defense mechanisms,which indicates the importance of care about parental rearing patterns and mental health of children.
