Tumor 2008;28(11):925-928
Objective: To analyze the differential protein expressions in highly-metastatic colorectal carcinoma cell lines LoVo and low-metastatic SW480 cells using proteomic analysis method and detect the biological molecule for early diagnosis of metastasis of colo-rectal carcinoma. Methods: Proteins in highly-metastatic LoVo cells and low-metastatic SW480 cells were isolated by two-dimension gel electrophoresis (Two -DE). Two-DE map was established by gel-silver staining and Coomassie brilliant blue staining. The well differentially expressed protein spots were screened by Image Master imaging. The specific protein spots were identified by peptide mass fingerprints using matrix-assisted laser desorption/time of flight mass spectrometry (MALDI-TOF/MS) and through searching NCBInr database using Mascot software. Results: Twenty one differential protein spots were screened and 5 differential proteins were identified. They included Ezrin protein, transcription elongation factor A, and lamin A/C which were up-regulated in LoVo cells and non-metastatic protein expressed in isoform a (NM23A) and heat shock protein 8 (HSPA8) which were up-regulated in SW480 cells. Conclusion: This study has found that the differential proteins are related with tumor growth, migration, adhesion and apoptosis. Our results provide theoretical basis for finding biological markers for early diagnosis of metastasis of colorectal carcinoma.

Objective To evaluate clinical application value of DWI and reservation of liver function in patients with chronic liver disease. Methods Thirty cases of healthy control group, and 60 case group with chronic liver disease,including both 30 chronic hepatitis B and 30 cirrhosis. liver function in case group was analysed by venous blood samples. Case groups were divided into three groups according to MELD score: <30 group in 27 cases, 30 to 36 group in 17 cases, >36 group in 16 cases. All cases underwent liver magnetic resonance DWI. Among the case group, 15 cases were followed-up twice of pre- and aftertreatment. DWI images were read, ADC values of liver parenchyma were measured and standardized with the cephalospinal fluid (CSF) at the same slice. Used SPSS 13.0 for windows to treat the data, group comparison of ADC values were treated by one-factor analysis of variance, interclass comparison each other by SNK method, comparison between pretherapy and post-treatment by paired-samples t test. Results Healthy liver parenchyma of the control group is homogeneous signal on DWI. ADC pseudo-color pictures showed green on the homogeneous areas. Slightly restricted area of chronic hepatitis B showed irregular scattered patchy in DWI images, 25 cases in right and left lobes, 5 cases only in right lobe of the liver. ADC pseudo-color pictures reaveled blue region in proliferation-constrained areas. Restricted areas of the liver parenchymal become more evident, also showed an irregular liver edge in 30 cases of cirrhosis. The standarized ADC average values were: the healthy group (0. 47 ±0. 02) × 10-3 mm2/s, chronic hepatitis B group (0. 37 ±0. 03) × 10-3 mm2/s, cirrhosis group (0. 36 ±0. 04) × 10-3 mm2/s( F =97.05,P <0. 05).The difference between healthy group and patients group was statistically significant (P < 0. 05 ). No statistically significant difference between groups of chronic hepatitis B and liver cirrhosis ( P > 0. 05 ).Average ADC values of MELD score among groups of < 30, 30 to 36, > 36 were ( 0. 38 ± 0. 02 ) ×10-3 mm2/s,(0.35 ±0.02) × 10-3 mm2/s, (0.32 ± 0.03) × 10-3 mm2/s respectively. There is a significant difference among the three groups (P <0. 05). After treatment, DWI of 15 patients with chronic liver disease showed reduction in restricted areas, and the average ADC value from pre-treatment (0. 33 ±0. 03) × 10-3 mm2/s increased to(0. 38 ±0. 03) × 10-3 mm2/s, MELD score from pre-treatment 36. 01 ±6. 00 reduced to 27. 83 ± 4. 86. Conclusion DWI of chronic liver disease showed patchy diffuse restricted areas; more severe of the liver cell damage was, more worse the liver function was and lower ADC values was. ADC values increased after effective treatment, liver function recoved and diffuse restricted areas of liver parenchyma reduced.

Objective To evaluate the value of MRI in diagnosis of craniopharyngiomas. Methods MRI findings of 52 craniopharyngiomas were analyzed retrospectively and correlated with pathology.Results 37 cases of all 52 cases craniopharyngiomas were located on suprasellar. Craniopharyngioma fluid collections were found to be uniformly hyperintense on T 2-weighted images. However, on T 1-weighted images, the signal intensity of the fluid ranged from hypointense to hyperintense, reflecting the presence of pathological contents in these tumors. Conclusion MRI is an effective method in diagnosis craniopharyngioma due to its direct multiplanar capabilities and sensitive signal changes.
