Objective:To explore the relationship between tobacco smoking and liver cancer risk.Methods:Cohort studies of cigarette smoking and risk of liver cancer were identified by searching MEDLINE and CBM databases from January 1989 to September 2009. Results from individual studies were combined synthetically by Meta analysis using R software and Meta package. Results:A total of 19 articles were included in our analysis. The cohort totally included 3 023 558 followed-up persons and 9 525 cases of liver cancer patients. The pooled relative risk (RR) of liver cancer was 1.49 (95%CI: 1.17-1.92) for smokers compared with non-smokers. The results showed a statistically moderate association between tobacco smoking and the risk of liver cancer. Subgroup analysis indicated that the pooled RRs for smoking were 1.53(95%CI : 1.29-1.83)for male smokers and 1.70(95%CI :1.17-2.48)for female smokers, respectively.Conclusion:Tobacco smoking is a risk factor for liver cancer in both males and females.

[ ABSTRACT] AIM:To investigate the inhibitory effect of ginsenoside Re on intimal hyperplasia induced by bal-loon-injury and to explore the role of NF-κB p65 signaling pathway in the process.METHODS:SD rats (n=40) were di-vided into 5 groups randomly: sham operation group, model group, low-dose ginsenoside Re group, middle-dose ginsen-oside Re group and high-dose ginsenoside Re group.The carotid artery intima injury model was established by 2F balloon catheters in all groups except the sham operation group.The day after modeling, the animals in model group and sham op-eration group were administered intragastrically with distilled water, and the rats in low-dose, middle-dose and high-dose ginsenoside Re groups were given ginsenoside Re at doses of 12.5 mg/kg, 25mg/kg and 50 mg/kg, respectively.After 14 continuous days, the morphological changes of the injured arteries were observed by HE staining and the lumen area, intima area and media area as well as the ratio of intimal area/media area were determined.The expression of tumor necrosis fac-tor-α( TNF-α) and interleukin-1β( IL-1β) were detected by real-time PCR.The proliferating cell nuclear antigen ( PC-NA) and nuclear factor-kappa B ( NF-κB) p65 were examined by immunohistochemistry.RESULTS:Compared with sham operation group, the vessel cavity was narrowed (P<0.01), the mRNA levels of TNF-αand IL-1β, and the protein ex-pression of PCNA and NF-κB p65 were increased in model group (P<0.05).Compared with model group, the vascular intimal hyperplasia was alleviated obviously (P<0.05), and the mRNA levels of TNF-αand IL-1β, and protein expres-
sion of PCNA and NF-κB p65 were decreased in medium and high-dose ginsenoside Re groups (P<0.05).CONCLU-SION:Ginsenoside Re inhibits the vascular neointimal hyperplasia induced by balloon-injury in rats, and the molecular mechanism may be related to the inhibition of NF-κB p65 signaling pathway.

Objective To investigate the effects of nerve growth factor (NGF) on the expression of 67-kDa laminin receptor (67LR) in human bile duct carcinoma QBC939 cells, and study the possible mechanism of perineural invasion and metastasis of bile duct carcinoma. Methods ( 1 ) The expression of a high-affinity receptor for NGF, TrkA, was detected by immunofluorescence staining. ( 2 ) QBC393 cells were pretreated by β-NGF at different concentrations ( 1, 10, 100,200 μg/L), and then the mRNA and protein expressions of 67LR were examined by Real-Time PCR and Western blot assay. QBC939 cells were divided into control group and β-NGF (1, 10, 100,200 μg/L) groups. (3) The ideal concentration of β-NGF was selected according to the results of previous tests, and then the mRNA and protein expressions of 67LR were re-examined by adding specific TrkA inhibitor K252a at different concentrations ( 100,200,300 nmol/L). QBC939 cells were divided into control group, β-NGF 100 μg/L group and K252a ( 100,200,300 nmol/L) groups. All data were analyzed by one-way analysis of variance or LSD-test. Results (1) A strong expression of TrkA was detected in the membrane of QBC939 cells. (2) The mRNA and protein expressions of 67LR in QBC939 cells were 0.35 ± 0.06 and 0. 32 ± 0.05 in the control group, 0.38 ±0.14 and 0.50 ±0.09 in the β-NGF 1 μg/L group, 0.62 ±0.14 and 0. 69 ±0. 13 in β-NGF 10 μg/L group, 0.90 ± 0.08 and 0.93 ± 0.07 in the β-NGF 100 μg/L group, and 0. 70 ± 0. 10 and 0. 76 ±0.07 in the β-NGF 200 μg/L group, there were significant differences among the five groups (F = 22. 4, 14. 6,P <0.05). The mRNA and protein expressions of 67LR in the β-NGF 100 μg/L group were significantly higher than those in the control group ( t = 19. 0, 21.0, P < 0. 05 ). (3) The mRNA and protein expressions of 67LR in the QBC939 cells were 0.35 ±0.10 and 0.41 ±0.10 in the control group, 0. 88 ±0. 14 and 0.84 ±0.10 in the β-NGF 100 μg/L group, 0.80±0.08 and 0.76 ±0.04 in the K252a 100 nmol/L group, 0.67 ±0.12 and 0.61 ± 0.09 in the K252a 200 nmol/L group, and 0. 43 ± 0.07 and 0. 50 ± 0. 12 in the K252a 300 nmol/L group, there were significant differences among the five groups ( F = 14. 1, 8. 9, P < 0.05 ). There were no significant differences in the mRNA and protein expressions of 67LR between the K252a 300 nmol/L group and the control group (t =1.02, 0. 85, P>0.05). Conclusion In bile duct carcinoma cells, NGF enhances the expression of 67LR by combining with TrkA, which might be the mechanism of NGF mediating perineural invasion of bile duct carcinoma.

Objective To study the influence of pulmonary ischemia-reperfusion (I/R) induced by cardio-pulmonary bypass (CPB) on pulmonary function and the preventive effect of nicardipine.Methods Sixteen patients scheduled for cardiac valve replacement were randomly divided into two groups : control group ( n = 8) and nicardipine group ( n = 8) . In nicardipine group nicardipine 0.02 mg kg-1 was given at the beginning of CPB; while in control group normal saline was given instead of nicardipine. All patients were operated upon under TIVA with large doses of fentanyl. Swan-Ganz catheter was placed via internal jugular vein after induction of anesthesia. Mean pulmonary arterial pressure (MPAP), pulmonary vascular resistance index (PVRI) and lung compliance were measured and calculated before CPB (T0 ), 5min after declamping of vena cava (T1 ), at tennination of CPB (T2) and at the end of operation (T3 ). At the same time points arterial and mixed venous blood samples were taken for determination of TNF-a, SOD and LPO concentrations and polymorphonuclear leukocyte (PMN) count, intrapulmonary PMN trapping (PMNa-PMNv) and blood gases and calculation of PaO2/FiO2 , P(A-2,)O2 difference and Qs/Qt. The vena cava cross-clamping time was defined as pulmonary ischemia time. Results (1) In control group MPAP, PVRI, PaO2/FiO2 and Qs/Qt were significantly deteriorating after vena cava declamping (T1-T3) as compared with the baseline valves (T0) (P
