Aim To investigate the effect of ASIC1 a ( acid-sensing ion channel 1 a ) on the pathological change of diabetes complication liver fibrosis and the proliferation and activation of hepatic stellate cell ( HSC-T6 ) stimulated by PDGF-BB under hyperglyce-mia. Methods Diabetes rats model was established by streptozotocin ( STZ) , and liver fibrosis rats model was induced by carbon tetrachloride ( CCl4 ) . Then, the liver extent of damage and the expression of ASIC1 a were observed in the diabetic rats, liver fibrosis rats and diabetes complication liver fibrosis rats. In vitro, after pretreated with amiloride, HSC-T6 was treated with high glucose for 24 h and then stimulated with PDGF-BB for another 24 h. The proliferation and acti-vation of HSC-T6 were observed, and the expression of ASIC1a, α-SMA and collagen Ⅰ were detected by Western blot. Results Compared with the control group, rats from diabetic group induced by STZ, liver fibrosis group induced by CCl4 , and the diabetes com-plication liver fibrosis rats co-induced by STZ and CCl4 were all observed with liver damage at different levels, and tissue injury of complication group was most seri-ous. However, the expression of ASIC1a in the three model groups was significantly increased compared to the control group. ASIC1a level was most obvious in the diabetes complication liver fibrosis rats. Amiloride pretreatment significantly decreased ASIC1 a expression and inhibited PDGF-BB mediated proliferation and the expression ofα-SMA and collagenⅠin HSC-T6 under high glucose environment. Conclusion High ambient glucose aggravates HSC activation and hepatic fibrosis, and this may be related with the increasing expression of ASIC1a.

CCAAT enhancer binding protein A (CEBPA) and its product transcription factor CCAAT enhancer binding protein α (C/EBPα) play pivotal roles in early granulocyte development. C/EBPα induces the transition and keeps the balance of differentiation and proliferation of myeloid progenitors. The mutation and dysregulation of CEBPA at transcription, translation or post-translation level lead to differentiation block and over proliferation of immature hematopoietic cells, which are important mechanisms of acute myeloid leukemia (AML). The mutation and dysregulation of CEBPA also provide clues for evaluating the outcome of AML patients and potential targets for differentiation-inducing therapies. This review focus on CEBPA mutation and AML, dysregulation of C/EBPα protein expression and AML, as well as C/EBPα protein and targeting therapy.

Objective To investigate the dynamic changes of blood-brain barrier(BBB) permeability after acute cerebral ischemia in rats with middle cerebral artery occlusion (MCAO) by dynamic contrast-enhanced(DCE)-MRI. Methods Sixty MCAO rat models were established by suture-occlusion method. All rats were divided randomly into twelve groups with different ischemia duration (3 hours, 6 hours, permanent) and reperfusion times (2, 6, 12 and 24 hours after reperfusion). Each group was examined by MRI at the time points. The BBB permeability parameters(Ktrans, Ve, Kep, rKtrans, rVe, rKep) were calculated by Siemens workstation and compared with Evans blue(EB) extravasation results. Multivariate analysis of variance (M-ANOVA), one-way analysis of variance (one-way ANOVA), Pearson analysis were respectively used to verify the influences of ischemia duration and reperfusion time on BBB permeability parameters, EB extravasation and relationships between parameters. Results In 3 hours and 6 hours ischemia duration groups, change of BBB permeability after reperfusion appeared biphasic. At 2 hours and 6 hours after reperfusion, BBB permeability increased, while rKtrans values and rVe values rose and rKep values dropped. BBB permeability decreased at 12 hours and increased again at 24 hours after reperfusion. The highest BBB permeability was observed at 6 hours after reperfusion. However, BBB permeability in permanent ischemia groups had uniphasic change, as its increase was rather mild as ischemia time went on. rKtrans values(1.99± 0.79)were positively correlated with rVe values(2.88 ± 1.78) (r=0.93, P<0.01) and negatively correlated with rKep values(0.66 ± 0.21) (r=-0.84, P<0.01). The negative correlation between rVe values and rKep valueswas also significant(r=- 0.80, P<0.01). EB extravasation results were consistent with MRI findings. Conclusions BBB permeability change was biphasic in reperfusion groups, while it was uniphasic in permanent ischemia groups. DCE-MRI may accurately reflect the changes of BBB permeability after acute cerebral ischemia. Both ischemic duration and reperfusion time had influences on BBB permeability. With prolongation of ischemic time, the duration of BBB permeability increase became shorter, BBB damage appeared earlier, with increased degree of ischemic damage.

Objective To investigate the dynamic change and its clinical significance of serum thymidine kinase 1 (STK1) in patients with non-small-cell lung cancer (NSCLC) when undergoing 4 cycles of chemotherapy. Methods We detected STK1 levels of 59 patients with NSCLC throughout 4 cycles of chemotherapy using Enhanced Chemiluminescence Western Blot and analyze its relationship with chemotherapy responses . Results STK1 levels with different chemotherapy regimens had no significant difference. STKK1 levels in patients with effective response were significantly lower after 4 cycles of chemotherapy. STK1 levels in patients with effective response were significantly lower than those in non-responders throughout 4 cycles of chemotherapy. The positive rates of STK1 in those with effective response were lower than those in non-responders after the last two cycles of chemotherapy. STK1 levels between lung squamous carcinoma and lung adenocarcinoma had no significant difference. Conclusion The detection of the changes of serum TK1 in patients with NSCLC undergoing chemotherapy is useful in evaluating the effect of chemotherapy and the later therapeutic schedule.

Objective To explore the expression plasma heat shock protein HSP90αand its clinical signifi-cance for lung cancer patients . Methods Plasma levels of HSP90α protein of 60 patients with lung cancer and 24 healthy individuals are detected by ELISA analysis . Results The average plasma levels of HSP90αprotein [(190.338 ± 105.861) ng/mL] in patients with lung cancer were significantly higher than in healthy con-trols [(41.020 ± 19.736) ng/mL, t = 10.480, P < 0.001]. The sensitivity of HSP90α is higher than CEA, NSE, CYFRA21-1. The sensitivity of HSP90α, CEA, NSE, CYFRA21-1 and STK1 is 100%. HSP90α is correlated with STK1 and metastasis (χ2 = 4.656, P = 0.031). Conclusions This study demonstrates that the plasma level of HSP90αprotein is a useful diagnostic biomarker in lung cancer. The sensitivity is much higher when HSP90αcom-bined with CEA, NSE, CYFRA21-1 and STK1.
