Objective: To analyze the association between hepatitis B virus (HBV) infection and pancreatic cancer. Methods: Retrospective analysis was performed to explore the positive rate of serum hepatitis B virus surface antigen (HBsAg) in patients with pancreatic cancer, lung cancer, diabetes mellitus and general population. Z test was used to compare the rate of HBV infection between the samples and general population. The rates among the samples were compared by Chi-square test. Results: A total of 3,701 registered patients seen in our hospital between January 1st 2003 and March 31st 2009 were collected. There were 230 pancreatic cancer patients with a positive rate of serum HBsAg of 16.1%, 1,188 lung cancer patients with a positive rate of serum HBsAg of 10.7%, and 2,283 patients with diabetes mellitus with a positive rate of serum HBsAg of 11.6%. There was no statistical significance in Z-test results between lung cancer patients and general population (Z=1.104, P=0.163), but the Z-test results between patients with diabetes mellitus and general population showed a statistical significance (Z=2.98, P=0.002). The positive rate of HBsAg was higher in pancreatic cancer patients than that in lung cancer patients (OR=1.60, 95% Cl: 1.077-2.382, r=5.487, P=0.019). Similar results were found between pancreatic cancer patients and diabetic patients (OR=1.46, 95% CI: 1.004-2.123, r=3.965, P=0.046). Conclusion: The positive rate of HBsAg is high in pancreatic cancer patients. There might be an association between HBV infection and pancreatic cancer.

Background and purpose:Previous studies have suggested Na+-Ca2+ exchanger isoform 1 (NCX1) as a key component of calcium homeostasis was involved in the tumorigenesis. However, the role of NCX1 and calcium signal in tumorigenesis of hepatocellular carcinoma (HCC) has not been explored. This study aimed to investigate the effect of NCX1 on cell proliferation and migration of HCC HepG2 cells in vitro and the possible mechanism.Methods:Both the real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot were applied to assess the expression of NCX1 mRNA and protein in normal hepatic cells (LO2), HCC cell line (HepG2), human normal hepatic tissues and hepatocellular carcinoma tissues. The change of intracellular calcium signal in LO2 and HepG2 cells via acti-vated NCX1 channel in the presence or absence of Na+ was examined by a confocal laser scanning microscope. The effects of NCX1 special inhibitor KB-R7943 on cell proliferation and migration of HepG2 cells were measured by MTT and cellscratch test.Results:Both mRNA and protein expression of NCX1 were higher in HCC tissues and cell line HepG2 than in the normal tissues and cell line LO2 (P<0.05). The activation of NCX1 channel induced a slight rise in cytoplasmic Ca2+concentration ([Ca2+]cyt) in normal cells, but caused a marked increase in cancer cells. And the NCX1 activation induced intracellular calcium increase was significantly reversed by NCX1 inhibitor KB-R7943 (P<0.05). Both NCX1-mediated proliferation and migration of HepG2 were also significantly attenuated by the KB-R7943 (P<0.05).Conclusion:NCX1 is up-regulated in HCC cells and tissues. The activation of NCX1 mediates intracellular calcium homeostasis. The inhibition of NCX1 activity can suppress the proliferation and migration of HepG2 cells. It is suggested that NCX1 may be involved in the development and progression of HCC.

Objective To evaluate the clinical value of susceptibility weighted imaging (SWI)in full-term neonatal hypoxic ische-mic encephalopathy (HIE).Methods Sixty-three neonates with HIE were collected and scanned by Siemens 3.0T superconducting MR scanner.Routine axial conventional MRI scan and axial SWI scan were conducted.Results In 63 neonates,a total of 29 cases with different degree of intracranial hemorrhage were scanned with SWI sequence.A total of 1 5 1 intracranial hemorrhages were found.Conventional MRI sequences were performed in 1 5 cases with different degree of intracranial hemorrhage.Only 78,43 and 88 hemorrhages were found by T1 WI,T2 WI and T2 Flair sequences,respectively.SWI were significantly superior to conventional MRI sequences in displaying the scope and boundary definition of hemorrhage.Conclusion SWI sequence is obviously better than the con-ventional MRI sequences in bleeding detection and displaying hemorrhage stove,and it provides a powerful imaging method for the clinical diagnosis and treatment.

Objective To assess the effects of rehabilitation training on lower extremity muscle function in stroke patients using velocity-encoded phase-contrast MRI ( VE-PC MRI). Methods Twenty-nine stroke patients at the convalescence stage were divided into a treatment group (14 cases) and a control group (13 cases).The subjects performed calf muscles stretches supine in a scanner bed with voluntary ankle flexion-extension movements.Imaging data were collected from the tibialis anterior muscle (TA),the medial head of the gastrocnemius (MG) and the soleus muscle (SOL) of the affected side.The treatment group also underwent rehabilitation including treadmill training,while the control group received only walking training without the treadmill.Barthel index (BI) and Berg balance scale (BBS) scores were measured after rehabilitation. Results Compared with baseline,the contraction velocity of the TA (phases 2 to 7),the MG (phases 12 to 18 ) and the SOL (phases 13 to 16) on the affected side increased significantly in the treatment group.In the control group,the contraction velocity of the calf muscles on the affected side improved,but fewer phases were significant-for the TA phase 4,for the MG phases 13 to 15 and for the SOL phase 15.In both groups,BBS and BI scores improved significantly compared with baseline.The average improvement in the treatment group was significantly greater than that in the control group. Conclusions Rehabilitation including treadmill training can improve calf muscle contraction function on stroke patients' affected side,and also their ADL performance and balance.VE-PC MR1 can provide quantitative in vivo measurements of the contraction function of stroke patients' calf muscles.
