OBJECTIVEThis study measures the glutaredoxin (Grx) gene and protein expression in umbilical vein endothelial cells upon exposure to Porphyromonas gingivalis (P. gingivalis) lipopolysaccharide (LPS). The involvement of the Akt-signaling pathway is also determined.

METHODSEA-hy926 cells were pretreated with 1,000 ng · mL⁻¹ P. gingivalis LPS for 4, 12, 18, and 24 h, and then real-time reverse transcription polymerase chain reaction was employed to detect Grx1 expression. The effect of Grx on Akt activity was investigated using Western blot for the control, LPS (1,000 ng · mL⁻¹ LPS), and carmus- tine (BCNU) groups (1,000 ng · mL⁻¹ LPS, and the EA-hy926 cells were pretreated with 25 μmol · ml⁻¹ BCNU for 30 min).

RESULTSGene expression of Grx1 significantly increased in LPS group compared with that in the control group. The Grx1 expression reached the peak level in 12 h, and the variation between the expression in 4 and 12 h was significant (P < 0.05). After 12 h, the protein levels of Grx and phosphorylated-Akt (p-Akt) significantly increased in the LPS group (P < 0.05), whereas the BCNU group showed a considerable decrease in both Grx and p-Akt expression levels (P < 0.05). Moreover, a slight difference was observed in the total Akt protein levels in the three groups (P > 0.05).

CONCLUSIONGrx expression increased upon exposure of EA-hy926 cells to the LPS. Akt activity could be inhibited by BCNU (a Grx inhibitor), which indicated that Akt might act as a downstream regulator of Grx.

Objective To compare the effect of silica-extraction method and Silico membrane based method in DNA purification from bones and teeth.Methods DNA samples were purified respectively with the silica-extraction method and MinElute PCR Purification kit from 6 bones and 8 teeth,then tested STR types by GlobalFiler? kits. And evaluated the two methods with the success rate and the peak height. Results Both of the two purification methods can successfully obtain the STR markers of the 14 samples. And there was no statistical difference between the two methods in the average peak height from bones and teeth. Conclusion The Silico membrane based method which have more advantages in operation is an efficient method to purify DNA from bones and teeth, and there is no significant difference compared with the silica-extraction method. But the cost is higher. It can be selectively used in forensic practice.

Objective To intervene and appraise the health literacy of diabetic patients entering contracts with family doctors in pilot communities,and learn the effect and feasibility of health literacy management by family doctors for diabetic patients.Methods By means of community intervention study and questionnaire survey,560 diabetic patients as mentioned above in Shanghai were subject to a baseline assessment on their health literacy,followed by management and routine follow-up on their diabetic health literacy.At the end of six months of comprehensive intervention,their health literacy was appraised again to observe the effects of such management.Results Six months of guidance and management found the average scoring of the health literacy of these patients 23.46 over the baseline,an increase of 36.8% of the patients in their compliance of the four basic diabetic diet behaviors,and an increase of 27.8% of them in regular and quantitative exercises.Conclusions It is feasible for community family doctors to carry out the health literacy management for diabetic patients contracted,and health literacy management can change the awareness and behaviors of such patients to some extent.

Objective To investigate the effects of leptin on Th17 cells and the possible mechanism. Methods The leptin-deficient ( ob/ob) mice and their homologous wild-type mice were used in the study.The percentages of Th17 cells in peripheral blood samples, spleen tissues and lymph nodes were measured by flow cytometry ( FCM) analysis.The splenic CD4+T cells, separated from the ob/ob mice and the wild-type mice by using magnetic beads,were respectively cultured with leptin at various concentrations and with anti-leptin neu-tralization antibody to evaluate the effects of leptin on Th17 cells.The quantitative real-time PCR was performed to analyze Th17 cell-related cytokines at transcriptional levels.The levels of IL-6 and IL-17A in the supernatants of CD4+T cell culture were measured with Luminex technology.Results Compared with the wild-type mice, the ob/ob mice showed lower percentages of Th17 cells in both peripheral blood samples and spleen tissues (0.49%±0.03%vs 1.29%±0.1%, 1.56%±0.22%vs 2.47%±0.11%).There was a decrease in the percentages of Th17 cells upon the in vitro treatment of CD4+T cells from wild-type mice with anti-leptin antibody.The per-centages of Th17 cells were increased in a dose-dependent manner upon the in vitro treatment of CD4+T cells from ob/ob mice with leptin.Moreover, the levels of IL-17A and IL-6 and the transcriptional levels of RORγt, IL-17A and IL-6 in leptin deficiency group were lower than those of wild-type group, but were increased upon the treatment with leptin.No significant difference with the transcriptional levels of TGF-βand IL-23 was ob-served between the two groups with and without intervention.Conclusion Leptin deficiency seriously hampered the generation of Th17 cells in mice and resulted in a decreased expression of RORγt, IL-17A and IL-6 at mRNA level.The treatment of CD4 T cells with leptin might promote the generation of Th17 cells through up-regulating the transcription of RORγt and IL-6.

Objective To investigate the effects of different doses of rosuvastatin on expression of liver X receptor(LXR) and caveolin-1 in cultured human monocyte-macrophage cells which induced by oxidized low density lipoprotein (ox-LDL).Methods The human monocyte-macrophage cells were divided into six groups:control group,ox-LDL group,different doses of rosuvastatin group (0.01 μmol/L,0.1 μmol/L,1 μmol/L,5 μmol/L).The expression of LXR mRNA and caveolin-1 mRNA were assayed by RT-PCR.Results LXR mRNA expression induced by ox-LDL in the control group and ox-LDL group were 1.00 ± 0.02,0.26 ± 0.02,and the difference was significant (t =56.39,P ＜ 0.001).Meanwhile,caveolin-1 mRNA expression in ox-LDL is (0.27 ± 0.01) fold than that in control (t =31.27,P ＜ 0.001).Meanwhile,There were significant differences among ox-LDL group and the different doses of rosuvastatin group in terms of LXR mRNA and caveolin-1 mRNA expressions (F =72.154,66.007,P ＜ 0.001).Along with the increase the doses of rosuvastatin,there was an increased trends of LXR mRNA and caveolin-1 mRNA expressions (P ＜ 0.05).Conclusion Rosuvastatin and upregulated the LXR mRNA and caveolin-1 mRNA expressions in a dose dependent manner.
