ObjectiveTo explore the role of peripheral blood intermediate monocytes in the pathogenesis of preeclampsia.MethodsFifty-two patients with established preeclampsia in Binhai County People's Hospital from October 2014 to October 2015, 42 healthy pregnant women and 42 healthy non-pregnant women were enrolled in this study. The percentage of intermediate monocyte subsets, ratio of positive cells and mean fluorescence intensity (MFI) of Toll-like receptor (TLR) 2, TLR4, CD64, and triggering receptor expressed on myeloid cell-1(TREM-1), and MFI of intracellular tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were evaluated by flow cytometry. The concentrations of IL-6, IL-8, IL-1β, IL-12P70 and TNF-α in serum were analyzed using Luminex liquid phase chip technology. Independent two samplest-test, analysis of variance, Mann-WhitneyU test, Kruskal-Wallis test and Pearson correlation analysis were used for statistical analysis.ResultsPercentage of intermediate monocytes was higher in preeclampsia patients [10.4%(5.3%-19.9%)]than in healthy pregnant women [6.6%(4.9%-7.8%)], and both were higher than in non-pregnant women [3.8%(2.4%-5.0)%](allP<0.05). The ratio of TLR4 and CD64 positive intermediate monocytes [(60.1±12.5)%vs (24.9±8.8)%; (85.3±5.4)% vs (67.4±7.5)%](t were 15.416 and 13.437, bothP<0.05), and MFI of TLR4 (50.3±10.2 vs 26.8±8.6), TREM-1(35.6±4.1 vs 28.6±4.7) and CD64 (39.8±5.2 vs 28.9±4.8) (t were 11.898, 7.707 and 10.454, allP<0.05) were higher in preeclampsia patients than in healthy pregnant women. MFI of intracellular IL-6 (32.3±4.7 vs 28.6±3.5) and TNF-α (44.6±6.3 vs 36.7±8.3) in intermediate monocytes of preeclampsia patients was also significantly higher than that of healthy pregnant women (t were 4.239 and 5.245, bothP<0.05). Serum concentrations of IL-6, IL-8 and TNF-α were higher in preeclamptic patients than in healthy pregnant women and non-pregnant women (allP<0.05). Furthermore, a positive correlation was found between the percentage of intermediate monocytes and the serum levels of IL-6 and TNF-α in preeclamptic patients (r were 0.397 and 0.347, bothP<0.05).ConclusionsMonocyte subpopulations from preeclamptic patients are abnormally skewed toward intermediate monocytes which have high expressions of TLR4, TREM-1 and CD64, and secret more proinflammatory cytokines such as IL-6 and TNF-α. Therefore, intermediate monocytes are specifically altered in preeclamptic patients and may play a role in the pathophysiology of preeclampsia.

[Objective]The oxidative injury of retinal pigment epithelium(RPE)plays a key role in the pathogenesis of age-related macular degeneration(ARMD). This study is to investigate the effects of endoplasmic reticulum stress and the vital transcriptional factor X-box binding protein 1(XBP1)in acrolein-induced oxidative damage of RPE.[Methods]RPE cells were treated with acrolein (75μmol/L)for 2~24 h,expression of glucose regulated protein 78(GRP78)and XBP1 was determined by Western blot analysis. After being transfected with XBP1 siRNA with 24 h,the expression of XBP1 was knocked-down in RPE cells. Protein level of Nrf2 and SOD2 was then determined by Western blot analysis and intracellular Reactive Oxygen Species(ROS)generation was determined by DCF staining. Acrolein was added for 8 h after being transfected with XBP1 siRNA or control siRNA for 24 h. Apoptosis was detected by TUNEL assay before and after the treatment. Subretinal injection of Cre or GFP adenovirus was performed in XBP 1flox mice. After 1 week the mice were sacrificed. Total RNA was extracted from mice eyecups using TRIzol and real-time RT-PCR was performed to determine the two XBP1 down-stream genes,ERdj4 and p58IPK. Cryosectioning and immunofluorescent staining were performed to look at the expression of XBP1,Nrf2 and SOD2 in mice RPE.[Results]Protein level of GRP78 was significantly un-regulated after exposure to acrolein for 2 and 4 h. XBP1 was activated after acrolein treatment for 6 h. Knock-down of XBP1 by siRNA down-regu?lates anti-oxidant genes expression and increased ROS generation in RPE cells. Loss of XBP1 exacerbates acrolein-induced cell apoptosis. XBP1 was knocked-down in the RPE of XBP1flox mice after subretinal injection of Cre adenovirus. Decreased mRNA level of ERdj4 and p58IPK,and decreased Nrf2 and SOD2 expression were seen in the Cre-injected group.[Conclusions]Acrolein induces ER stress and activates XBP1 in RPE cells. Knock-down of XBP1 down-regulates anti-oxidant genes expression ,increases ROS generation,and exacerbates acrolein-induced cell apoptosis. XBP1 plays a role in the anti-oxidant defense in the RPE cells.

Objective To up-regulate the expression of Glil gene in periodontal ligament stem cells ( PDLSCs) and to explore the effect of Glil gene on PDLSCs proliferation and osteogenesis differentiation by establishing Glil gene adenovirus vectors. Methods Subcloned Glil to viral backbone vector Adtrack-CMV and transfered the established vector to 293T cells, which was to acquire the virus particles. Trans-fected aim cells,namely PDLSCs,with these virus. Detected its effect on PDLSCs proliferation with CCK-8 assay, and detected the expression of Glil and the bone-related markers ALP and Runx2 through Western blot. Results An adenovirus vector, which were over expressed Glil gene, was successfully constructed and transfected to PDLSCs. Compared with the empty vector group and normal group, the over expressed one had a much slower proliferation rate in CCK-8 assay (P=0. 003). Western blot showed that ALP and Runx2 can be overexpressing os-teogenic differentiated after PDLSCs successfully transfected with the Glil gene. Conclusion Over expressing Glil gene would lead to a much slower proliferation rate in the PDLSCs and an increase of the bone-related markers. It is concluded that Glil can enhance the osteogenic dif-ferentiation capacity in PDLSCs.
