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 explore the distribution of ABO blood group in Tibetans population and their genetic relationship. Methods Data of ABO blood group of 28 Titetan populations were collected from China and India. The gene frequencies were processed by Phylip3. 68 and MEGA4. 1 genetic analysis software pack, and the Nei's genetic distance was imported and the genetic relationship was analyzed. Results The distribution of ABO blood group among Gansu, Qianghai, Sichuan, Yunnan, Tibet, and India was 0 ＞ A ＞ B ＞ AB. The nation index and genetic distance were 0. 63 ～ 0.98 and 0 ～0. 0072, respectively. Conclusion There is probable historical relationship among the ancestors of these Tibetan populations, but the differentiation incident of Tibetan population living in different area in history was different, so that their distribution of gene frequencies is diversified.

Objective To explore the function of high-intensity focused ultrasound in the treatment of allergic rhinitis.Methods To treat 46 patients who have allergic rhinitis for a long time with the instrument of CZB high-intensity focused ultrasound. Results We made a follow-up visit for 3 momths after the surgery,the symptom of stuffy nose van- ished from the 46 patients who were treated with the high-intensity focused ultrasound,and they haven't appeared sneezes again. Only 6 patieats have a little dear nasal mucus in the early morning. They don't have any complication and the se- quda. Conclusion The trearment with high-intensity focused ultrasound has the actual effect. Under reasonable therapeutic dose,the patients does not have the complication,and it is easy to do,it is really a kind of physical therapy method that can be promoted.

Objective To study the relationship between blood uric acid(BUA)level and oxidative stress in the elderly. Methods One hundred and eighteen healthy subjects who aged 60years and over were recruited.They were divided into 3 groups according to the serum uric acid level:(1)Control group:BUA 142-416 μmol/L;(2)Hyperuricemia group Ⅰ:BUA 417-470 μmol/L;(3)Hyperuricemia group Ⅱ:BUA＞470 μmol/L.Serum xanthine oxidase(XO)activity,superoxide dismutase(SOD)activity,total antioxidation capacity(TAOC)and peroxide concentration were examined. Results (1)No significant differences in TAOC[control group:(8.40±2.09),Hyperuricemia group Ⅰ:(8.13±1.92)and Hyperuricemia group Ⅱ:(7.95±1.54)U/ml,all P＞O.05)and in SOD activity[control group:(80.57±15.44),Hyperuricemia group Ⅰ:(81.37±11.92)and Hyperuricemia group Ⅱ:(87.45±11.38)U/ml,all P＞0.05)among the 3 groups were found.The serum peroxide level and XO activity were significantly higher in hyperuricemia group Ⅰ and Ⅱ[XO activity:(9.17±1.68) vs.(9.32±1.87)U/ml,all P＜0.05;serum peroxide:(149.5±25.7)vs.(150.7±23.1)μmol/L,all P＜0.05]than in group control[XO activity:(7.81±1.84),serum peroxide:(122.5±33.8)].(2)Multifactorial regression analysis showed TAOC was related to age,triglyceride and uric acid(all P＜0.05),XO activity was related to uric acid(P＜0.05)and peroxide concentration was related to age and uric acid(all P＜0.05). Conclusions This study supports the presence of the xanthine oxidase-related oxidative stress in the elderly with hyperuricemia.

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.

Objective To find the X-ray characteristic and diadynamic method in congenital defect of muscular layer in stomach wall. Methods Six cases confirmed by operation and pathology were collected,underwent eight standing abdomen plain films,underwent 5 decubitus abdomen plain films in 6 cases. Results The appearances in standing plain film of freeing gas under diaphragm, eventration of diaphragm, passing through the whole abdomen of gas and liquid plane, vanished gastriole were found in 6 cases. Superior border of liver was found in 4 cases.The appearances in decubitus abdomen plain films of abdominal distension, increasing gas gathered in umbilical region, vanshed fat line in abdominal wall were found in 4 cases. Conclusion Large part of typical cases could be diagnosis by x-ray and clinical appearance.
