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 In order to protect the natural resources of Swertia bimaculata which has been destroyed seriously,the method of artificial propagation by way of tissue culture have been systematically studied.Methods The stems,leaves,and stems with buds which were from the seedlings germinated from the seeds on the initial medium were taken as explants.These explants were cultured on MS culture media by adding different portions of hormones at various cultural conditions.Results The stems were the best material in speeding propagation among the three explants.The proper initial medium for the stems was MS+ BA 0.5 mg/L+saccharose 3.0%,the optimum medium for proliferation was MS+BA 0.5 mg/L+IBA 0.1 mg/L+saccharose 3.0%,and the best medium for rooting was 1/2MS+NAA 0.5 mg/L+saccharose 1.5%.Conclusion Tissue culture of S.bimaculata could make its propagation rapid,its resources preserved,and its utilization last.

Objective To investigate the effect of combined application of mannitol and monosialoganglioside on neurological function and its efficacy in brain edema after intracerebral hemorrhage. Methods 92 cases of cerebral edema in patients with cerebral hemorrhage in our hospital, were randomly divided into groups, each group of 46 cases, the control group on the basis of the treatment of mannitol (125mL per times, once per 8h) treatment, the study group on the basic of control group received monosialogangliosides (20mg per times, once daily), 10d for a course of treatment, determination of serum indexes, neurological functions were recorded. Results The effective rate of control group was 71.74%, which was lower than 91.30% of the study group, there was significant difference (P < 0.05); compared with control group after treatment , in study group the intracranial pressure, intracranial hematoma, edema decreased, the urine volume increased, National Institutes of Health Stroke Scale (NIHSS) and quality of life score decreased, interleukin (IL-1β), high sensitive C reaction protein (Hs-CRP), IL-6 and IL-8 levels decreased, Na+-K+-ATP enzyme increased, the ratio of cerebrospinal fluid albumin and serum albumin, matrix metalloproteinase (MMP-2) and MMP-9 decreased, there were significant differences (P < 0.05). Conclusion The effect of the combined application of mannitol and monosialoganglioside on cerebral edema after cerebral hemorrhage is exact and could improve neurologic function.

Objective To study the abnormal findings and metabolic alterations of the brain in chronic hepatic disease with MRI and 1H magnetic resonance spectroscopy (1H-MRS) for better understanding the clinical significance of pallidal hyperintensity and the role in the diagnosis and treatment of hepatic encephalopathy (HE) . Methods Brain MRI and 1H-MRS examination were performed in 50 patients with chronic hepatic disease and 20 healthy volunteers. The pallidus index (PI) was calculated and the height of resonance peaks of Glx was measured. The correlation between PI and Child/Pugh classification, and the association between blood ammonia and the spectroscopic alterations were studied. Pre-and post-therapeutic comparative study was also conducted in 5 cases with chronic HE. Results PI was gradually increased from healthy volunteers to patients with chronic hepatitis and liver cirrhosis (1.01?0.04, 1.06?0.09, and 1.18?0.09), and the differences in PI value among them were significant (F=22.294, P
