AIM: To investigate the expression of iNOS in the lung of HPS rats treated with tumor necrosis factor-? monoclonal antibody(TNF-?-McAb) and to investigate the therapeutic mechanism of TNF-?-McAb on hepatopulmonary syndrome.METHODS: Male Sprague-Dawley rats,weighing(250?25)g,were randomized to sham operation group,common bile duct ligation(CBDL) group and CBDL+TNF-? McAb treatment group.Histopathological changes of the lung tissue were evaluated by hematoxylin and eosin staining.The mRNA expression of iNOS in the lungs of hepatopulmonary rats was examined by RT-PCR,while the changes of iNOS in the protein level were evaluated by immunohistochemistry and Western blotting.RESULTS: The inflammatory responses in the CBDL rats treated with TNF-?-McAb decreased than that in CBDL group.Compared to CBDL group,the distribution of iNOS protein and the mRNA expressions in the lung tissue in TNF-?-McAb group were inhibited.CONCLUSION: TNF-?-McAb inhibits the expression of iNOS and plays a role in the treatment of HPS.

Objective To investigate the diagnostic value of macrophage migration inhibitory factor (MIF) for hepatocellular carcinoma (HCC).MethodsThe research was divided into 2 parts,including testing research and confirmatory research.The clinical data of 269 patients with HCC ( group A) and 390 individuals (including 135 patients with hepatic cirrhosis,106 with benign hepatic diseases and 149 healthy individuals,control group A) who were admitted to the Zhongshan Hospital of Fudan University from January to May,2004,and 173 patients with hepatic cancer (group B) and 257 individuals (including 86 patients with hepatic cirrhosis,79 with benign hepatic diseases and 92 healthy individuals,control group B ) who were admitted from August to December,2004,and 80 patients with HCC who received radical hepatic resection in January 2005 were retrospectively analyzed.Samples of plasma of patients in the group A and individuals in the control group A were collected before operation.Samples of plasma of patients received radical hepatic resection were collected preoperatively and at postoperative day 3,7 and 30.HCC and adjacent issues of patients in the group A were collected.The levels of MIF in the plasma and tissues were detected by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry,respectively.Non-normal distribution data were described as M( QR).Differences between the groups were analyzed by using the Mann-Whitney U test,and the relationship between the levels of MIF in the plasma and tissues was detected by the Spearman correlation coefficient.The diagnostic value of MIF was analyzed by the ROC curve.ResultsThe levels of MIF in the plasma of patients in the group A and individuals in the control group A were 85.7 μg/L (58.8 μg/L) and 15.5 μg/L(31.6 μg/L),respectively.The levels of MIF in the plasma of the patients with hepatic cirrhosis,benign hepatic diseases and healthy individuals were 24.9 μg/L (12.6 μg/L),12.5 μg/L(7.3 μg/L) and 13.2 μg/L (7.7 μg/L),respectively.There was a significant difference in the level of MIF between the group A and the control group A (F =54.235,P < 0.05 ).The area under the ROC curve reached peak when the level of MIF in the plasma was 35.3μg/L.Compared with the control group B,the vdues of AUC,sensitivity and specificity were 92.1%,90.7% and 93.4% in the group B.The levels of MIF of the patients with HCC before operation and at 3,7,and 30 days after operation were 81.0 μg/L(54.0 μg/L),76.1 μg/L(47.5 μg/L),50.9 μg/L (40.7 μg/L) and 18.7 μg/L ( 15.1 μg/L),respectively.The levels of MIF decreased with time passed by,and were back to normal at 30 days after the operation.The median expressions of MIF in the HCC and adjacent issues were 0.083 and 0.007,respectively,with a significant difference ( U =3.975,P < 0.05).The expression of MIF in the plasma was positively correlated with its expression in the HCC tissue ( r =0.759,P < 0.05 ).ConclusionMIF plays an important role in the genesis and development of HCC and has potential to be one of the molecular markers for the diagnosis of HCC.

Objective By analyzing the expression of cluster of differentiation 74 (CD74) in hepatocellular carcinoma (HCC) and HCC cell lines,the correlation between the level of CD74 expression and the patients' prognosis was investigated.MethodsThe expression of CD74 in high metastatic potential HCC cell lines(MHCC-LM3,MHCC-97H),low metastatic potential HCC cell line( MHCC-97L),and no metastatic potential HCC cell line(Hep-G2) were estimated by Western blot.The paraffin embedded tissues which include intra-tumor and paratumor tissues were collected from 320 patients who had received HCC curative surgical resection and 5 normal liver tissues from the donors of liver tranplantation.The high density tissue micro-array was made of these specimens. Immunol-histochemistry was applied to discover the different levels of CD74 in tumor,paratumor and normal liver tissues.Survival curves were generated by the Kaplan-Meier method and verified by the Logrank test.Cox proportional hazards regression analysis was applied to estimate the prognostic factors in multivariate analysis.ResultsThe expression level of CD74 was significantly higher in low metastatic potential and no metastatic potential HCC cell lines (MHCC-97L 1.224 ±0.014,Hep-G2 1.374 ±0.006) than that in high metastatic potential ones( MHCC-LM3 0.622 ±0.078,MHCC-97H 0.732 ± 0.083 ).Significant differences can be found between the groups (t =- 13.308,- 16.849,- 10.177,- 13.436,- 17.057; P <0.01 ).Meanwhile,in tumor tissues,the CD74 was expressed positively in 221 patients and negatively in 99 patients.But CD74 was expressed slightly in paratumor and negatively in 5 normal liver tissues.There's no significant differences between the groups categorization according to age,HBsAg,cirrhosis,AFP level,tumor number,tumor size,tumor capsule,blood vessel invasion,Edmondson Grades and tumor nodes metastasis classification (TNM) stages (x2 =0.053,0.141,1.200,0.000,0.277,1.975,0.263,1.044,0.000,0.433 ; P > 0.05 ),except gender (x2 =3.954,P < 0.05).Kaplan-Meier method showed that patients with positively expression of CD74 had better prognosis than others (x2 =5.620,P < 0.05 ).Cox proportional hazards regression analysis showed that CD74 was a significant and independent prognostic factor of survival [ hazard ratio (HR) =0.721,95%confidence interval (CI) =0.522 - 0.996,P < 0.05 ].Conclusion The expression of CD74 in hepatocellular carcinoma could be a biomarker of the prognosis and there's some potential correlation with cancer cell apoptosis.

Aminoacyl-tRNA syntheses (AARS) can catalyze the adenosine triphosphate (ATP)-dependent acylation of their cognate tRNA(s) with a specific amino acid. They can be seen as an index to reflect the energy metabolic rate of ischemic brain cells in ischemic penumbra. This study examined the relationship between arginyl-tRNA synthetase (ArgRS), one of the AARS, and cerebral ischemia in rats. The model of middle cerebral artery occlusion (MCAO) was established in rats. The expression levels of ArgRS protein and mRNA were detected in rat brain tissues at different time points following MCAO by Western blotting and RT-PCR, respectively. The results showed that the MCAO model was successfully established. Western blotting and RT-PCR analysis revealed that the ArgRS protein and mRNA were expressed in brain cells in both ischemic and normal penumbra tissues. The expression levels of ArgRS protein and mRNA peaked at 6 h after MCAO and decreased gradually. At 24 h, the expression levels of ArgRs protein and mRNA in ischemic penumbral tissues were lower than those in normal tissues. The expression levels of ArgRS mRNA and protein in ischemic penumbra varied with ischemic time, suggesting that the energy metabolism of brain cells in penumbra changed dynamically after ischemia to ensure the endogenous self-protection of the body. The brain oxygen supply should be improved as soon as possible, especially within 6-12 h after ischemia, so as to meet the demand for energy metabolism in ischemic penumbra and make sure the cell structure remains stable.
