OBJECTIVE: To observe the effect of the polyglycol (PEG) modification of trimeric ? peptide(?3) on it’s anti-metastasis ability. METHODS: Using adhesion test to study the effects of ?3 and ?3-PEG on the adhesion of tumor cells to FN. Using artificial basal membrane to study the effects of ?3 and ?3-PEG on the invasion and recombination of basal membrane of tumor cells. RESULTS: Comparing to negative control,?3 and ?3-PEG could both inhibit the adhesion of SMMC-7721 and HCCLM6 tumor cells to FN with time-dependently(P

PFTK1,an important member of cyclin dependent kinase Cdc2 family,is over expressed in many malignancies.PFTK1 involves in multiple processes,such as regulation of cell cycle,tumor invasion and metastasis,and the Wnt signal transduction pathway,which has a significant impact on prognosis of tumor.

Objective The purpose of this study was to evaluate the importance of the interhospital transport of critically ill pediatric patients by analyzing the epidemic characteristics of pediatric patients transported from 2009 to 2012.Methods Nine thousand two hundred and thirty-one referral patients from January 2009 to June 2012 were evaluated by a cross-section study.Epidemiological data such as sex,age,seasons,and referral radius were collected.Results Among all the interhospital transport of critically ill pediatric patients,male to female ratio was nearly 2.24 to 1 and 87.39％ (8067/9231) patients were neonates and infants.Of all patients,66.32％ (6122/9231) patients were from department of pediatrics,neonatology or gynaecology and obstetrics in referring hospitals.The distribution of referring department among years was statistically significant in referring patients (x2 =227.53,P ＜ 0.000 1).Among the patients,56.88％ (5251/9231) were transported over 150km radius and only 12.18％ (1124/9231) patients in 50 km.52.89％(4882/9231) were transported in spring and winter.The seasonal distribution of interhospital transport of critically ill pediatric patients was statistically significant(x2 =1201.88,P ＜0.000 1).The majority of referral telephones were received between 9 AM to 12 AM.Conclusion With the limitation of equipment and technical measure in primary hospitals,critically ill pediatric patients should be transported to tertiary hospitals.According to the epidemiological characteristics of interhospital transport of critically ill pediatric patients,some measures should be adopted for the timely,safe and effective interhospital transportation.

About the malignant tumor in China,the hepatocellular carcinoma mortality is second only to lung cancer and serious threat to the life and health of the masses.Furthermore,because most patients has been in advanced cancer during medical treatment,so had lost the chance of one-stage surgical resection.However,the sensitivity of hepatocellular carcinoma to chemotherapy,radiotherapy and other treatments are poor.Transcatheter arterial chemoembolization is the main method of the treatment for patients those have lost the chance of operation,though the clinical effect is significant,the inadequate is also presence,such as tumor necrosis,incompletely clear,residual tumor nidus and the damage of the immune function after operation.Recombinant adenovirus p53 gene can validly infect tumor cells,transcription and expression of p53 protein,it also regulate the expression of related genes inhibiting tumor cell growth and induce cell apoptosis directly or indirectly.It is increasingly highly attention that recombincanting rAd-p53 with transcatheter arterial chemoembolization(TACE) to treat hepatocellular carcinoma.In order to evaluate the clinical value and promising future,we will make a brief summary for the research progress in this area in recent years.

Rituximab in the combination of CHOP regimen has been widely used as the standard treatment of several kinds of B cell non-Hodgkin lymphoma (B-NHL),but there are still about 1/3 of the late B-NHL patients become primary and secondary resistant to the drug.Recently,many translational research progress in malignant lymphoma promoted the development of promising candidate drugs for the treatment of lymphoma.The advances in translational research field were summarized in this manuscript.

Objective To investigate the protective effect of total flavonoids of drynaria on hemorrhagic shock reperfusion renal injury.Methods The 30 Sprague-Dawley rats were randomly divided into 3 groups: sham operation group, experimental group (hemorrhagic shock group) and drynaria fortunei group, 10 in each group. In drynaria fortunei group and experiment group, the blood from the femoral artery was with drawn until the mean arterial pressure reached 40 mmHg in 90 min, and then the withdrawn blood transfusion were reinfused and blood pressure recovered to the base value of 90%. The rats of drynaria fortunei group were given intraperitoneal injection of Drynaria total flavonoid 300 mg/kg, and experimental group and sham operation group were injected with 3 ml physiological saline. Blood creatinine (SCr) levels, the renal cell apoptosis index, the expression of Bcl-2 and mRNA Bax in kidney were detected. Results Compared with the experimental group, serum SCr (78.36 ± 5.31 mmol/Lvs. 151.43 ± 11.8 mmol/L) of drynaria fortunei group decreased significantly (P<0.01); the renal cell apoptosis (19.56% ± 4.37%vs. 14.31% ± 2.83%), the expression level of Osteopractic rats of Bax group mRNA (1.24 ± 0.05vs. 0.91 ± 0.07) of drynaria fortunei group decreased significantly; and the Bcl-2 mRNA (0.65 ± 0.05vs. 1.38 ± 0.07) and the expression level and Bcl-2/bax ratio (0.52 ± 0.06vs. 1.51 ± 0.08) of drynaria fortunei group increased significantly (P<0.01).Conclusions The drynaria total flavonoids on rats with hemorrhagic shock and resuscitation of renal injury has a protective effect, and its mechanism may improve the expression of Bcl-2 and mRNA, increase the ratio of bcl-2/bax, and inhibit  or block the apoptosis of renal tissue.

In order to improve the effect of teaching and teachers' ability,make our teaching methods adapt to the social development,the department of Endocrinology used the method of preparing lessons collectively in our teaching.We found that the method not only made the the supply of teachers reasonably but also made good contribution to the students' culture.Practice testified that the method of preparing lessons collectively could adapt to the new model of cultivation and create substantial results.

Facing the diverse social environment and development, several aspects of higher clinic medical education,such as educational philosophy,personnel cultivating goal and mode,are undertaking all kinds of shift,which can be embodied in the medical curriculum reform.

Objective The anti-HCV positive results obtained from ELISA assay was confirmed by using protein microarray, and then the difference of detection rate of different antibody function domains was studied through observing low risk population. Methods The HCV mixing antigen, core area antigen, NS3 domain antigen, NS4 domain antigen, NS5 domain antigen were spotted on the slide. The 48 serum samples, which was positive HCV detected by using ELISA assay, were chosen from the specimens applying to investigation of viral hepatitis seroepidemiology in 2001, and furthermore the antibodies containing different function domain were detected by using protein microarray. Results The negative results were obtained from different domains of 15 samples. Then 1-4 antibodies from 33 samples were positive. The total detection rate of anti-C, anti-NS3, anti-NS4, anti-NS5 was 51.5%, 51.5%, 48.5% and 57.6% respectively. In these above statistics, the detection rate of anti-C from Zhoushan, Quzhou, Wenzhou, Shaoxing was 53.3%, 33.3%, 44.4%, 66.7% respectively; the detection rate of anti-NS3 was 33.3%, 100%, 55.6%, 66.7% respetively; the detection rate of anti-NS4 was 60.0%, 0%, 33.3%, 66.7% respectively; 抗the detection rate of anti-NS5 was 66.7%, 0%, 44.4%, 83.3% respectively. Conclusion The difference of distribution of different antibody function domains existed through studying low risk population. Moreover, the protein microarray assay was highly specific for detecting and identifying HCV antibody in low risk population.
