Objective To study the effects of a cirrhotic environment on the metastasis of liver cancer in mice.Methods Male BALB/c mice were randomly assigned to two groups:cirrhosis group and control group.The cirrhosis group was treated by an injection of carbon tetrachloride intraperitoneally.H22 liver cancer cells were directly implanted under the capsule of each group after cirrhosis was established.The animals were sacrificed at 1,2,and 3 weeks after the operation.The metastatic behavior of the cancer cells was observed by the naked eye and microscopically.Additionally,the adhesion ability of the liver was assessed by measuring the expression of vascular cell adhesion molecule 1 (VCAM-1),E-selectin,and E-cadherin.Results After the operation,the cirrhosis group showed an obvious metastatic tendency in both intrahepatic (14/19) and extrahepatic ways (4/19),compared with the control group's intrahepatic (5/17) and extrahepatic ways (1/17) (P<0.05).Immunohistochemisty for VCAM-1 and E-selectin showed a significant increase in the cirrhosis (P<0.05).However,there was no difference observed in the E-cadherin between the cirrhosis and control group.Conclusion A cirrhotic liver environment may promote the metastasis of liver cancer cells by increasing the ability of liver adhesion.

Objective To investigate the features of risk factors of minor stroke with CISS classification in Guangdong Province. Methods We retrospectively investigated the patients admitted within 3 days of the occurrence of a minor stroke, and were classified by CISS criteria as large artery atherosclerosis (LAA), cardiogenic stroke (CS), penetrating artery disease (PAD), other etiology (OE), undetermined etiology (UE). Results In this study, 303 pa-tients met the inclusion criteria of minor stroke. The highest percentage of the risk factors included hypertension (72.3%), hyperlipidemia (58.3%), and diabetes mellitus (39.9%). Among different subtypes, 41.9% were diagnosed with LAA, and 50.8% with PAD. Plasma triglyceride (TG)(1.765 ±1.18)mg/L vs.(2.19 ±1.84)mg/L,P=0.03], apolipoproteinsB (ApoB) [(0.95±0.29)mg/L vs.(1.11±0.46)mg/L,P=0.009]C-reactive protein (CRP) [(6.63±11.30) mg/L vs.(3.42 ±5.02)mg/L,P=0.042] and ApoB/ApoA1 ratio [(0.754 ±0.25)mg/L vs.(0.875 ±0.49)mg/L,P=0.019], differed significantly between group LAA and PAD. Conclusion Hypertension, hyperlipidemia and diabetes mellitus are the major risk factors of minor stroke. The most common subtypes of the minor stroke patients in Guangdong Province are LAA and PAD, and detecting their TG, apoB, CRP level and apoB/apoA1 ratio might help subclassify minor stroke according to CISS.

AIM: To study the expression of telomerase inhibitor Pinx1 in acute leukemia cells and during the differentiation of acute promyelocytic leukemia cells, and to realize its effect on telomerase activity. METHODS: Realtime quantitative PCR with fluorescence probe hybridization was used to measure the expression of Pinx1 and hTERT mRNA in acute leukemia cells and during differentiation of NB4 cells induced by ATRA. The correlations between Pinx1 and hTERT expression were also analyzed. RESULTS: Pinx1 mRNA expression in acute leukemia samples (0.00312, 5.42?10 -4-0.024) was significantly higher than that in normal bone marrow mononuclear cells (7.89?10 -4, 0-0.00863, P

Objective To evaluate the accuracy and feasibility of time-resolved immunofluorometric assay (TRI FA) for detection of HBsAg based on Abbott automated chemiluminescence immunoassay(CMIA),so as to carry out this project in primary hospitals,and provide reference for individual antiviral strategy and prediction of therapeutic effect.Methods Serum of 157 patients infected with hepatitis B virus were detected with CMIA and TRIFA,specimens with HBsAg titers exceeding the detection limit were firstly diluted,then performed quantitative analysis.HBsAg levels were divided into 4 groups:≤100 IU/mL,101-1 000 IU/mL,1 001-20 000 IU/mL,and > 20 000 IU/mL,quantitative correlation between two methods was analyzed.Results The linear regression equation of two methods was Y=2.323X-896.3,correlation coefficent r=0.943,P<0.001.CMIA was as a reference,4 groups were divided for analysis,results showed that when detected specimens was at low concentration of HBsAg,TRIFA value was low compared with CMIA method,while detected specimens was at high concentration of HB sAg,CMIA value was high,two reagents had good consistency in the detection of different concentrations of HBsAg(both P<0.05),when concentration was at 1 001-20 000 IU/mL,consistency was the best.Conclusion The accuracy of two reagents in the quantitative detection of HBsAg is similar,and the best correlation of detection value is 1 000-20 000 IU/mL.TRIFA assay has wide application for its low-cost and easy to be operated,which is especially suitable for primary hospitals.

Objective To study the long-term effect of argon plasma coagulation (APC) combined with proton pump inhibitor (PPI) on Barrett esophagus (BE). Methods A total of 36 patients, histologically proven as having BE from 2004 to 2007, were enrolled to underwent a therapy of APC plus PPI. The patients were re-examined on endoscopy at 1, 6 and 12 months after first APC and once a year thereafter.Results A total of 48 APC sessions were given to 36 patients with a mean number at 1. 33 per patient. The effective rate of reversal of BE was 100%. The follow-up was accomplished for all patients in 14-51 months with a median of 36months. The total recurrence rate (RR) of BE reached 16. 7% (6/36). The 1-year and 2-year RRs were 2. 8% (1/36) and 11.1% (4/36), respectively. The logistic regression analysis suggested that 2-year and total RRs were related to APC sessions ( P < 0. 01 ). Conclusion The therapy of APC combined with PPI for BE is safe and of long-term effects.
