A complete explanation of the new idea,grounds,spirit,inner-contradiction of the 3 major documents in the new framework of epileptic knowledge re-defined by International League Against Epilepsy was made in accordance with the International League Against Epilepsy original articles.And the different recognition about them nowadays existed among our nerologists was also deeply explored.

OBJECTIVETo evaluate remineralization efficacy of an arginine containing dentifrice on initial enamel carious lesions in vitro.

METHODSHuman enamel blocks with early lesions were prepared and randomly divided into three treatment groups: negative control group (distilled and deionized water), positive control group (fluoride containing dentifrice and 0.14% sodium monofluorophosphate), and test dentifrice group (8.0% arginine and 0.14% sodium monofluorophosphate). The lesions were subjected to a pH-cycling regime for 10 days. Surface enamel microhardness of the enamel blocks from each group was measured before and after pH cycling, and the surface microhardness recovery was calculated. Then, specimens were analyzed for enamel fluoride uptake (EFU) through acid etching method, after which they were treated in demineralization solution for a 2 h period of acid challenge. The other specimens were sectioned and examined through polarized light microscopy.

RESULTSIn the test dentifrice group, microhardness recovery and EFU were significantly higher than those in the negative control and positive groups. The test dentifrice group was significantly resistant to the acid challenge compared with the other groups. Conspicuous remineralization of enamel subsurface lesions was observed under polarized light microscopy among samples treated with test dentifrice, whereas the control groups showed no significant changes on enamel subsurface lesions.

CONCLUSIONThis study presents the potential superiority of Pro-Argin dentifrice over conventional fluoride dentifrice in promoting the remineralization of initial enamel lesions.

Whether or not an abormal expression of IL-6 mRNA in PBMNCs from IDDM patientswas examined using a hihgly sensitive,specific and semiquantitative protocal,i.e.reverse tran-scription and polymerase chain reaction (RT-PCR).The relative levels of IL-6mRNA in PBM-NCs from 12 early IDDMpatients (8.20?3.85yr),29 newly diagnosed NIDDM patients(54.85?9.12yr)23 normal childrens (8.20?3.26yr) and 12 normal adults (31.92?11.22yr)weredetermined.Significantly high expresion levels of IL-6 mRNA were found in PBMNCs from pa-tients with IDDM (P

Objective To investigate the expression level of Gas6 in patients with Immune Thrombocytopenia (ITP) and its clinical significance.Methods The experimental group was peripheral blood samples collected from 35 cases diagnosed with ITP in hematology department of Changhai Hospital in Shanghai from October 2013 to December 2015.Control group was peripheral blood from 35 healthy examined individuals at the same time.After separating plasm from the two group samples,the protein level of Gas6,IFN-α,IL-4,IFN-γ and IL-17 were measured by Enzyme-linked immunosorbent assay (ELISA),comparison of expressional level of the two groups was measured by t test.Pearson correlation analysis was used to decide the relation between Gas6 and cytokines such as IFN-α.Results The expression level of Gas6 in experimental and control groups was 27.28±7.56 ng/ml vs 20.51±5.39 ng/ml (t=4.314,P＜0.000 1);IFN-γ was 221.67±57.64 pg/ml vs 45.32 ±16.79 pg/ml (t=17.38,P＜0.000 1);IL-4 was 113.86±26.48 pg/ml vs 49.87±14.98 pg/ml (t=12.44,P＜0.000 1);IL-17 was 168.96±47.88 pg/ml vs 109.56±28.97 pg/ml (t=6.28,P＜0.000 1);IFN-α was 34.83±8.12 pg/ml vs 29.89 ± 5.76 pg/ml (t=2.936,P=0.004 5),all with statistical differences (P＜0.05).Pearson analysis showed that Gas6 was positively related with IL-17,IL-4,IFN γ (r=0.564,0.486,0.449,P＜0.05) and there was difference statistically,but Gas6 was not correlated with IFN-α.Conclusion Gas6 may participate in the disease formation of ITP through affection on cytokines secreted by Th cell subsets,and it was the potential therapeutic and predicted target for this disease clinically.

OBJECTIVETo investigate the role of interleukin-17 (IL-17) in alveolar fluid clearance in mice with acute lung injury (ALI) and explore the possible mechanism.

METHODSSixteen IL-17-knockout mice and 16 wild-type mice were both randomized for intratracheal instillation of PBS (control) on lipopolysaccharide (LPS) to induce ALI. Forty-eight hours after the treatments, the wet-dry ratio (W/D) of the lungs, IL-8 in the bronchoalveolar lavage fluid (BALF) and histopathological changes of the lung tissues were examined. The expressions of epithelial sodium channel α subunit (α-ENaC) was detected with Western blotting and liver kinase B1 (LKB1) was detected with immunohistochemistry.

RESULTSCompared with wild-type mice treated with LPS, IL-17 knockout mice showed significantly decreased W/D of the lungs (9.739∓3.3 vs 5.351∓0.56) and IL-8 level in the BALF (67.50∓7.33 vs 41.00∓3.16 pg/mL) following LPS challenge. Pathological examination revealed reduced alveolar edema fluid aggregations and lower lung injury score in IL-17 knockout mice with also higher expression levels of ENaC and LKB1 compared with the wild-type mice.

CONCLUSIONKnocking out IL-17 in mice not only alleviates inflammation of the lung tissue following ALI but also reduces the loss of ENaC protein and promotes alveolar fluid clearance, mechanism of which is probably associated with LKB1.

Pancreatitis has not been reported in allogeneic stem cell transplant (allo-SCT) recipients with cyclosporine in China. This article presented a case of acute pancreatitis in a 49-year-old patient with AML-M2a who received allogeneic stem cell transplant from her HLA identical sister. The preparative regimen consisted of busulfan and cyclophosphamide. The cyclosporine A, short-term methotrexate and antilymphocyte globulin (ATG), were used to prevent the graft-versus-host disease (GVHD). Clinical and laboratory signs of acute pancreatitis were found in the patient on day 20 post-transplant. A diagnosis of acute pancreatitis was made although the pancreas was apparently normal at abdominal contrast-enhanced tomography and ultrasonography. She recovered with supportive care and reduction of cyclosporine dose. In conclusion, cyclosporine is the probable cause of pancreatitis in this patient.

BACKGROUNDMicroRNAs (miRNAs) control gene expression by destabilizing target transcripts and inhibiting their translation. Aberrant expression of miRNAs has been described in many human diseases, including schizophrenia. However, the effects on miRNA expression in response to antipsychotic treatment in peripheral circulation have not been thoroughly examined.

METHODSUsing quantitative real-time PCR (qRT-PCR), We quantified the expression of seven candidate miRNAs in plasma samples of 40 first-episode schizophrenics before and after antipsychotic treatment. The patients were all treated with risperidone and achieved remission in 1 year.

RESULTSCompared with the baseline, the expression levels of miR-365 and miR-520c-3p were significantly down-regulated after 1 year of risperidone treatment (P < 0.001). There were no significant correlations between the clinical symptoms and the expression levels of these two miRNAs (P > 0.05).

CONCLUSIONSThis study analyzed possible circulating miRNAs in response to antipsychotic monotherapy for schizophrenia, the further mechanism need to be confirmed.

OBJECTIVETo analyze the promoter methylation levels of p15, CDH1, DAPK and HICI genes of patients with myelodysplastic syndrome (MDS) and explore the relationship between the level of methylation and clinical features.

METHODSDNA methylation levels of p15, CDH1, DAPK and HICI in peripheral blood (PB) or bone marrow (BM) samples from 52 MDS patients were detected by real-time quantitative PCR. The correlation of the methylation level with clinical features and hematological findings was analyzed. 38 de novo AML patients and 46 normal individuals served as controls.

RESULTSThe methylation levels of p15, CDH1, DAPK and HICI were 16.23 ± 21.69, 6.59 ± 9.39, 0.14 ± 0.11 and 7.81 ± 9.70 in BM, and 14.96 ± 20.16, 6.00 ± 9.26, 0.12 ± 0.14 and 6.74 ± 9.72 in PB, respectively from 18 MDS patients, and the difference between BM and PB was not statistically significant (P > 0.05). The methylation levels of p15 (14.70 ± 18.17) and CDH1 (6.61 ± 8.79) genes in high risk (RAEBI/II) MDS were significantly higher than in low risk (RCMD/RARS/5q-, p15: 1.99 ± 1.59, CDH1: 1.23 ± 1.14 and RCMD, p15: 3.02 ± 3.42, CDH1:1.53 ± 2.06) MDS or control (p15: 1.69 ± 1.82, CDH1: 1.01 ± 1.12) (P < 0.05). The methylation levels of DAPK gene had no difference among subtypes of MDS, and that of HIC1 gene only differed between RAEB I/II (9.16 ± 11.95) and control (2.49 ± 2.26) (P = 0.042). The difference of methylation levels of p15, CDH1, DAPK and HICI in BM was statistically significant among subtypes of MDS (P = 0.001, 0.003, 0.039, 0.023, respectively). And so did of p15 and DAPK in PB (P = 0.013, 0.006, respectively). The methylation level of p15 and CDH1 was significantly correlated with IPSS classification and blasts percentage in BM.

CONCLUSIONSp15 and CDH1 genes are special hypermethylation genes in MDS. Methylation level of HIC1 gene showed an upward tendency from low risk to high risk MDS.
