Objective To observe the morphological changes of mice cortex neuron cultured in vitro under different temperature, and the expression of skeleton protein (?-tubulin) in the neuron, and to study the relationship between ?-tubulin and heat shock protein 70 (HSP70). Methods The cerebral cortex neuron of embryonic mice was cultured in vitro. The cultured neuron was put in different temperature 7 days later. To observe the morphological changes of the neuron using optical microscope and the changes of the expression of ?-tubulin and HSP70 under different temperature using laser scanning confocal images. Results Optical microscopy indicated that drifting cells increased, and neural network became sparse in 38℃; some cells necrosed in 39℃; most cells necrosed, cell broke to pieces, axons drifted or disappeared in 42℃. Results of laser scanning confocal images indicated that after hyperthermia the fluorescence intensity of ?-tubulin was lower than that of controls, and the fluorescence intensity declined as the temperature elevated. The fluorescence intensity of HSP70 showed a bell-shape distribution curve, i.e. the highest value emerged at 39℃, whereas the lower values appeared at 37℃ and 42℃. Conclusion Heat stress leaded to the morphological changes of neuron. The disordered of skeleton protein may be responsible for the changes and HSP70 may take part in the process.

Objective:To observe the expression of microRNA (miRNA, miR) -7850 in renal cancer tissues, and to explore the effect of miR-7850 on the proliferation and migration of renal cancer cells and on the regulation of serine proteinase inhibitor B3 (SERPINB3) gene expression.Methods:Real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-7850 in renal cancer tissues and renal cancer cell lines. The renal cell carcinoma cell line with the lowest expression of miR-7850 was selected, and the negative control sequence (miR-NC) and miR-7850 mimics were transfected into renal cell carcinoma cells by Lipofectamine 2000 transfection reagent, respectively, which were defined as miR-NC group and miR-7850 group. qRT-PCR was used to detect the expression of miR-7850 in transfected renal cancer cells. The cell proliferation and migration ability after transfection were detected by cell counting kit-8 (CCK-8) method and transwell experiment. Bioinformatics prediction and dual luciferase reporter gene experiments were used to verify the target gene of miR-7850. qRT-PCR and Western blot were used to detect the expression of target genes in renal cancer cells after transfection.Results:Compared with adjacent tissues (5.95±0.44), the expression of miR-7850 in kidney cancer tissues (1.19±0.33) was lower ( P<0.01). Compared with immortalized proximal renal tubular epithelial cells (1.01±0.07), the expression of miR-7850 was lower in renal cancer cell lines ( P<0.05), and the lowest in A498 cells (0.13±0.01) ( P<0.01). The expression of miR-7850 in the miR-7850 group (7.46±0.93) was significantly higher than that in the miR-NC group (1.01±0.08) ( P<0.01), indicating successful transfection. Compared with the miR-NC group, the cell proliferation ability of the miR-7850 group was significantly reduced ( P<0.05). The number of migrating cells in miR-NC group and miR-7850 group were (139.50±12.31) and (75.09±16.05) cells, respectively, and the cell migration ability in miR-7850 group decreased significantly ( P<0.01). Bioinformatics technology shows that the target gene of miR-7850 was SERPINB3. The dual luciferase reporter gene experiment confirmed that miR-7850 can target the SERPINB3 gene ( P<0.05). Compared with the miR-NC group, the expression of SERPINB3 in cells of miR-7850 group was significantly reduced ( P<0.05), as well as the CDK4, CyclinD, Snail and Vimentin. Conclusions:miR-7850 is lowly expressed in renal cancer tissues and cell lines. miR-7850 can inhibit the proliferation and migration of renal cancer A498 cells, which may be related to its inhibition of SERPINB3 gene expression.

Protective measures should be established in order to prevent further damage of vessel, relieve pain of patients and ensure smooth progress of the treatment.

Objective To compare distribution difference in risk factors of patients with first-ever ischemic stroke (IS) of different age and gender.Methods A total of 1027 patients admitted to the neurological department in Shanghai Renji Hospital with first-ever IS were recruited and divided into young adult group ( ＜ 50 years old),middle-aged group (50-80 years old),and very old group ( ＞ 80 years old)according to their ages.Risk factor analysis included history of smoking,high alcohol consumption,hypertension (HT),diabetes mellitus (DM),heart diseases,atrial fibrillation (AF) and family history of cardiovascular diseases.Results Female patients were globally older than male patients (71.1 vs 65.7,P ＜ 0.001 ) at the first attack of IS and having higher prevalence of DM (26.8％ vs 19.2％,P =0.004 ),heart diseases (28.8％ vs 19.2％,P＜0.001) and AF (7.6％ vs 3.9％,P=0.009).However,female patients were less likely to drink heavily ( 1.0％ vs 31.6％,P ＜0.001 ) or smoke (4.4％ vs 59.9％,P ＜0.001 ) than the male patients.The rates of smoking and heavy drinking in young adult group were higher than that in other two groups.Patients in very old group had higher prevalence of heart diseases and AF but lower proportion of positive family cardiovascular diseases history than patients in other two groups.HT and DM were equally frequent among three groups.In young adult group,female patients were more likely to have heart diseases and family history of heart diseases (P =0.015 and P =0.048).In middle-old group,HT,DM,heart disease and AF were more common in women than in men (P =0.021,P =0.004,P =0.001 and P =0.039).Conclusion There are differences in risk factor distribution in patients with first-ever IS of different age and gender.Therefore,screening and health education should be performed in allusion to different risk factors.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

Objective:To explore the expression of long non-coding RNA LINC00630 in bladder cancer cell lines, and to explore the effect of interference with its expression in vitro on the proliferation and migration of bladder cancer cells.Methods:Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LINC00630 in bladder cancer cell lines 5637, BIU-87, T24, J82 and normal bladder epithelial cell line SV-HUC-1. The bladder cancer cell line with the highest LINC00630 expression was selected for follow-up experiments, then the cell line infected with the control lentivirus was used as the control group, and the cell line infected with the lentivirus that could interfere with the expression of LINC00630 was used as the experimental group. qRT-PCR was used to detect the expression of LINC00630 in the two groups of cells. MTS method and cell scratch test were used to detect the proliferation and migration abilities of cells in the two groups. qRT-PCR was used to detect the expression of neuregulin 1 (NRG1) mRNA in the two groups of cells, and Western blot was used to detect the expressions of NRG1 protein, cell proliferation-related proteins (cyclin D3 and CDK2) and cell migration-related proteins (Vimentin and N-cadherin) in the two groups of cells.Results:Compared with SV-HUC-1 cells (1.05±0.17), the expression of LINC00630 was significantly increased in all bladder cancer cell lines (all P < 0.01), and the expression was highest in J82 cells (relative expression 5.83±0.42). Compared with J82 cells of the control group, the expression of LINC00630 in J82 cells of the experimental group decreased (0.18±0.02 vs. 1.00±0.05, t=14.36, P < 0.01); from day 2 of transfection, the cell proliferation activity of the experimental group was lower than that of the control group (all P < 0.05). The cell scratch closure rate of the experimental group was lower than that of the control group [(27.4±7.1)% vs. (66.0±5.4)%, t = 4.31, P < 0.01]. Therelative expression of NRG1 mRNA in the experimental group was lower than that in the control group (0.34±0.03 vs. 1.07±0.24, t = 2.99, P < 0.05). Compared with the control group, the expressions of NRG1 protein, cell proliferation-related proteins and cell migration-related proteins in the experimental group were reduced. Conclusions:LINC00630 is up-regulated in bladder cancer cell lines, and interference with LINC00630 may inhibit the proliferation and migration of J82 cells by down-regulating the expression of NRG1 gene. LINC00630 may be a new molecular target for the treatment of bladder cancer.
