Objective To examine mutations in the WT1 and PLCE1 gene in three Chinese families with autosomal recessive steroid-resistant nephrotic syndrome (SRNS) once mutations in NPHS2 had been excluded. Methods Peripheral blood samples were collected for genetic analysis from three probands of three Chinese families and their parents, and two probands' siblings, and 50 adult volunteers with normal urinalysis. Genomic DNA was isolated from peripheral blood leucocytes. Ten exons and exon-intron boundaries of WT1, and 31 exons and exon-intron boundaries of PLCE1 were amplified by polymerase chain reaction (PCR). Mutational analysis was performed by DNA sequencing directly and RFLP (restriction fragment length polymorphism) and/or PCR. Results No mutation in both WT1 and PLCE1 was identified in three probands from three Chinese families with autosomal recessive SRNS. However, three variants of WT1, 126C>T, ⅣS5-64A>G and 903A>G, and 13 variants of PLCE1, -134A>G, 810T>C, 960G>A, ⅣS11-28C>G, ⅣS15+26A>C, 4724G>C, ⅣS20+40C>T, ⅣS21+64G>A, ⅣS22-26T> A, 5320C>T, 5780A>G, ⅣS27+24A>G and ⅣS31 +48_49insT, were detected in three probands and some controls, indicating that all these variants were gene polymorphisms. WT1 polymorphism ⅣS5-64A>G, and PLCE1 polymorphism ⅣS22-26T>A were novel. Conclusion All the encoding exons and exon-intron boundaries of both WT1 and PLCE1 in three probands are examined, and no causative mutations in WT1 and PLCE1 axe found, suggesting that mutation in WT1 and PLCE1 genes is not a major cause of the Chinese families with autosomal recessive SRNS.

Objective To investigate the histopathological and ultrastructural changes of corneal epithelium induced by erlotinib in mice.Methods Totally 30 6-8 weeks old male BALB/c mice were divided into three groups:Control group (n =12),experimental group (n =12),another 6 mice did nothing as the blank control.Experimental group used erlotinib eye drops and control group used PBS in both eyes,four times per day.At 1 day,7 days and 14 days after the intervention,corneal fluorescence staining (FL) was observed by slit lamp and graded.On the fourteenth day after the intervention,the eye balls of mice were taken,and the histopathological and ultrastructural changes of corneal epithelium and epithelial cells were observed by optical microscope and electron microscope,respectively.And protein of cornea was measured by Western Blot.Results Before the intervention,there was no significant difference in FL scores between the experimental group and control group (P ＞ 0.05).At 1 day,7 days and 14 days,FL score of experimental group was significantly higher than the groups of non-intervention,the difference was statistically significant (all P ＜ 0.05).While FL score of control group was not statistically significant before and after intervention (all P ＞ 0.05);Compared between two groups,there were statistical differences at 7 days,14 days in FL score (all P ＜ 0.05).In the experimental group,the histopathological changes of murine corneal epithelial cells had disorderly arrangement,increased layers of cells,and the inflammatory cells.Under electron microscope,the morphology of corneal epithelial surface cells was irregular and partially detached.The number of microvilli,desmosomes and hemidesmosomes were significantly decreased when compared to the control group.The expression of p-EGFR in experimental group was significantly less than that in control group,the difference was statistically significant (P ＜ 0.05).Conclusion Erlotinib can damage the tissue structure of corneal epithelium and ultrastructure of corneal epithelial cells in mice.And the mechanism is probably that erlotinib influence the corneal epithelium by inhibiting the EGFR activation.

ObjectiveTo investigate the effects of sleep deprivation on expressions of Mir-132,mir-134 in the different regions of rat brain.MethodsAll the male SD rats were divided into control group ( normal sleep group),sleep deprivation (SD).The modified multiple platform method (MMPM) was used to establish sleep deprivation model.Mir-132,mir-134 level was detected by real time PCR.ResultsMir-132 were significantly increased in SD groups in hippocampus compared with the control groups ( 51.87 ± 8.13 vs 67.25 ± 7.59 ) (P ＜0.01 ).Mir-134 were significantly decreased in SD groups compared with the control groups( 1.82 ±0.15 vs 1.45± 0.12 )(P ＜ 0.01 ).There were no statistically significant differences in cortex and thalamus (P ＞ 0.05 ).Cortex mir-132 level in SD group and control group was 1.57 ±0.10,1.48 ±0.11 respectively,and it was 1.37 ±0.09,1.36 ±0.11 in thalamus;Cortex mir-134 level in SD group and control group was 98.26 ± 5.17,100.80 ±4.15respectively,and it was 97.56 ± 6.28,91.01 ± 4.07 in thalamus.ConclusionThe upregulation of mir-132 and downregulation of mir-134 implies that two miRNAs did opposite actions in the processes of sleep deprivation.This findings indicate that hippocampus mir-132,mir-134 levels in the SD rat may reflect associated depressive patho-physiological processes.

Objective To evaluate the effect of online teaching platform in clinical neurology prac-tice. Methods The participants were medical undergraduate students in the process of clinical practice in Department of Neurology of XiJing hospital, who were divided into the traditional practice teaching group (n=77) and online platform auxiliary practice teaching group (n=90), respectively carry-ing out the corre-sponding rotation practice teaching . Unified objective structured clinical examination was given to two groups of students to implement departmental rotation examination , and investigation was made among teachers and students on the evaluation of the effect of practice. SPSS 19.0 was used to do t test to the two sets of corresponding evaluation data. Results Total score of departmental rotation examination in online platform auxiliary practice teaching group (69.33 ±2.74) was significantly higher than traditional teaching group (67.23±2.50) (P=0.000). Scores of basic theories, skill and operation, clinical case analysis in online platform auxiliary practice teaching group were significantly higher than traditional teaching group (P<0.05). However, medical record writing scores in online platform auxiliary practice teaching group (7.39± 1.09) were significantly lower than the traditional teaching group (8.03±1.03) (P=0.000). Teachers' eval-uation of practice effect was obviously higher in online platform auxiliary practice teaching group (12.33± 0.52) than that in traditional teaching group (10.67 ±1.03) (P=0.005). Students' evaluation of interest in learning, content arrangement, teachers' sense of responsibility, evaluation of teaching ability, practice effect were obviously higher than that of traditional teaching group (P<0.05). Conclusion This study preliminary has achieved good practical effect by using online auxiliary teaching platform, and got high evaluation by both teachers and students. Inter-active communication and sharing of resources is easy in the online plat-form of practice teaching . On-line platform will help students develop with clinical neurology diagnosis thinking.

Objective To evaluate the safety and efficacy of bivalirudin in patients with acute myocardial infarction ( AMI) and diabetes undergoing primary percutaneous coronary intervention ( PCI) . Methods BRIGHT was a multicenter , randomized , controlled study which enrolled AMI patients underwent primary PCI in 83 Chinese centers between August 2012 and June 2013.All patients were randomly assigned to receive bivalirudin , heparin or heparin plus tirofiban. This study was a prespecified subgroup analysis of the BRIGHT study.A total of 465 diabetics in the BRIGHT study were included , consisted of 168 in the bivalirudin group , 137 in the heparin group and 160 in the heparin plus tirofiban group .Primary endpoint was net adverse clinical event ( NACE) at 30 days, which was defined as a composite of major adverse cardiac and cerebral events ( MACCE ) and any bleedings .Results The incidences of NACE at 30 days were significantly different among three arms ( Bivalirudin:10.1% vs.heparin:16.1% vs.Heparin plus tirofiban 20.6%, P=0.031 ) .Compared with heparin plus tirofiban , bivalirudin was associated with a significantly lower NACE rate (P<0.01).Bivalirudin treatment significantly reduced bleeding events at 30 days compared with heparin and heparin plus tirofiban ( 3.0% vs.7.3% vs.12.5%, P <0.01 ) .The 30-day incidences of MACCE and stent thrombosis were similar among the three groups ( P>0.05 ) . Conclusions The use of bivalirudin has dramatically reduced the rate of bleeding and did not increase the incidence of ischemic events compared with heparin and heparin plus tirofiban , indicating a better safety and efficacy profile of bivalirudin during primary PCI in patients with AMI and diabetes .

Aim To investigate the effect of Ajuga decumbens(HBG), Poria cocos(FL) and their combination on the metastasis of invasive breast cancer cells and the related mechanisms.Methods We conducted several assays including cell adhesion assay, scratch assay and transwell invasion assay.Western blot analysis was employed to detect the expression of associated proteins of EMT and MAPK signaling pathway.Results FL,HBG and their combination could significantly inhibit the adhesion, migration and invasion of MDA-MB-231 and SK-BR-3 cells.HBG and FL had markedly synergistic effect, and the best compatibility ratio was 10 ∶1.HBG, FL and their combination could reverse EMT of breast cancer cells, which increased the levels of epithelial biomarkers, such as β-catenin, E-cadherin and ZO-1, and reduced the levels of mesenchymal biomarkers, such as vimentin.Moreover, treatment of the cells with HBG, FL and their combination resulted in marked inhibition of phosphorylation of ERK1/2, JNK and p38.Conclusions The combination of HBG and FL have the ability to inhibit breast cancer cell invasion by targeting the expression of MAPK pathway as well as suppressing the epithelial-to-mesenchymal transition.
