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 study the value in predicting the postoperative pulmonary function of the patient with quantitative MSCT.Methods 16-slice spiral CT scanning of lung was performed in 24 patients with pulmonary carcinoma before and after the operation during eupnea.Then the postoperative forced expiratory volume in one second(FEV1) and forced vital capacity(FVC)were calculated according to the preoperative lung capacity which was measured by quantitative MSCT,FEV1 and FVC which were measured by pulmonary functional test(PFT),then the results of FEV1 and FVC predicted by MSCT were compared with that two months later after operation.Results There was significant relativity in FEV1 and FVC between predicted by MSCT before operation and measured by PFT after operation ( P was 0.190 and 0.563 respectively).Conclusion Quantitative MSCT can predict the postoperative pulmonary function exactly,which provides dependable reference data for lung resection in the patients.with pulmonary carcinoma.

Objective To evaluate the applied value of MSCT lung volumes measurement in diagnosing chronic obstructive pulmonary disease(COPD).Methods 40 patients clinically diagnosed with COPD and 26 healthy volunteers as control group underwent MSCT chest CT scanning . The relevant indicators of lung volumes were measured and calculated in comparison with the indicators of clinical lung function . The accuracy and sensitivity of every indicator of lung volumes in forecasting and screening COPD by using ROC curve method were evaluated.Results There were significant differences between the control group and the COPD group in the full expiration volume(Vex),the full inspiration volume(Vin),Vex/Vin and the ratio of the change of lung volume(P

Objective To know the present sanitary status of bathing beach in Haikou,and provide the scientific data for improving the assessment of microorganisms contamination of bathing beach. Methods The routine water quality data and related meteorological data of the bathing beach were collected from 2007 to 2009. In July 8th-10th 2009,a high grade bathing beach and an ordinary one were selected,four sampling sites were selected where the contamination by feces were often seen,the number of swimmers was the largest,the samples were collected from the deep-water areas and sand beach respectively,and fecal coliform and enterococcus were examined. Results The concentration of fecal coliform was(1 085.8?538.8)cfu/L in water and(120 000.0?32 659.9)cfu/1 000 g in sand,and the E.faecalis was(32.5?19.1)cfu/L in water and(2 425.0?689.8)cfu/1 000 g in sand. The numbers of the two kinds of bacteria in water decreased with the increase of distance from the land. The concentration of bacteria was positively correlated to the day's rainfall(P

0.05).Singnificant difference of p21 positive rates was showed between tumor lack of blood supplies and arterial blood (?

Objective To study the relationship among SCT features of tumor margin and tumor size, immunohistochemical findings, grade of cell differentiation, and to explore the potency of tumor marginal features on multiphase spiral CT for evaluating biological behavior of small hepatocellular carcinoma (SHCC).Methods Multiphase spiral CT scans were performed in 30 patients with 33 lesions of SHCC (≤3.0 cm in diameter) confirmed histopathologically. Of these patients,26 were male and 4 were female. Immunohistochemical and HE staining were performed in surgical samples of all patients with SHCC. All samples' size was measured and the number of masses in each patient was counted.Results Of all masses, 6 were complete capsule, 15 incomplete capsule and 12 non-capsule. In multiple linear regression analysis, the pseudocapsula presentation and completion of SHCC on SCT were positively related with tumor size and VEGF expression, negatively with CD34 and p21, and were not in association with p53 and histological grade. Tumor size was the strongest contributor to pseudocapsula completion(R=0.5115), and then VEGF(R=0.2917), CD34(R=-0.2981) and p21(R=-0.2726), which had the similar standardized regression coefficients.Conclusion Tumor size is the strongest relative factor that influenced pseudocapsula presentation and completion of SHCC. VEGF always expressed positively in SHCC with complete pseudocapsula, and negatively in the group of SHCC with incomplete pseudocapsula or without pseudocapsula. In the group of SHCC with incomplete pseudocapsula or without pseudocapsula, p21 always express positively. Neither p53 expression nor histological grade is in association with the pseudocapsula presentation and completion of SHCC on SCT.
