Objective To explore the protective effect of brain-derived neurotrophic factor (BDNF) on cultured rat cortical neurons against glutamate (Glu)-induced injury and its mechanism. Methods Cortical neurons were primarily cultured from 1-day-old newborn Sprague-Dawley rats and then cultured for 7 d. The cortical neurons were divided randomly into 3 groups: control group,Glu group and BDNF group after identified with neuron-specific enolase (NSE) immunostaining. The cells of BDNF were treated with 50 ng/ml BDNF on day 6 for 24 h followed by cultured with 50 ?mol/L Glu for 0.5 h. While,the cells of Glu group were cultured with 50 ?mol/L Glu for 0.5 h on day 7. The control cells received no such treatments. On day 8,cell viability were determined by the colorimetric MTT assay. The morphological features of the neuron cells were observed under AO/EB fluorescence microscopy. Expressions of p75NTR,JNK and ERK were observed using Western blot analysis. Results On day 8,the primary cortical neurons grew well. BDNF protected cortical neural cells from Glu injury. Cell viability of BDNF group was (1.14?0.06),significantly higher than that of Glu group (0.72?0.10,P

AIM:To investigate the regulatory effects of phosphatylinositol 3-kinase/protein kinase B (PI3K/PKB) signaling pathway on the expression of osteopontin ( OPN) in transforming growth factor-β1 ( TGF-β1 )-induced hu-man hepatic stellate cells .METHODS:Human hepatic stellate cell line LX-2 was cultured in DMEM and stimulated by TGF-β1 at the final concentration of 2.5, 5, 10 and 20 μg/L for 24 h or at final concentration of 10 μg/L for 12 h, 24 h and 48 h.LX-2 cells were pretreated with wortmannin , a specific inhibitor of PI3K/PKB signaling pathway , at final con-centration of 0.1 μmol/L for 1 h, followed by incubation with TGF-β1 at final concentration of 10μg/L for 24 h.The cells were collected.The expression of OPN was detected by real-time PCR and Western blotting .RESULTS: In LX-2 cells, the expression of OPN was apparently elevated when incubated with TGF-β1 .With the increase in TGF-β1 concentration or the extension of incubation hours , the expression of OPN was increased gradually in a dose-and time-dependent manner with certain limits.LX-2 cells pretreated with wortmannin and incubated with TGF-β1 had a significant decrease in the OPN expression as compared with control group (P<0.01).CONCLUSION:The expression of OPN in TGF-β1-induced LX-2 cells is regulated by the PI3K/PKB signaling pathway.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. <br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. <br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P<0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP<0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P<0.05). <br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

OBJECTIVETo investigate the effect of MSX2 interference on epithelial-mesenchymal transitions (EMT) of pancreatic cancer cell line PANC-1.
METHODSThree vectors containing short hairpin RNAs (shRNAs) of MSX2 (shMSX2-1, shMSX2-2, and shMSX2-3) and the empty vector (negative control) were transfected separately into PANC-1 cell line with Lipofectamine2000. Real-time RT-PCR and Western blotting were used to observe changes in the expressions of MSX2, E-cadherin, and vimentin in the cells. CCK-8 assay was used to assess the changes in the cell growth, and wound scratch assay and Transwell assay were employed to evaluate the cell invasion and metastasis after the transfection.
RESULTSAmong the 3 shRNA, shMSX2-1 showed the highest interference efficiency. MSX2 knockdown by the specific shRNA of MSX2 significantly increased E-cadherin expressions, lowered vimentin expressions, and suppressed the invasion, metastasis and proliferation of the cells (P<0.05). MSX2 knockdown also resulted in morphological changes of the cells into cobblestone-like cells in close contact. RT-PCR results revealed significantly reduced mRNA expressions of the transcription factors snail and twist (P<0.05) without affecting slug and zeb1 expressions in the cells with MSX2 knockdown. Conclusion MSX2 knockdown can reverse EMT and induce MET in PANC1 cells, in which process the transcription factors snail and twist may play a role.
