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 To discuss the pe rc utaneous laser disc decompression (PLDD) therapy by adopting the Nd: YAG Laser C L-50 Device under X-ray monitor supervision. Methods A total of 378 cases were included in this study. There was 198 males and 180 fe males, the age ranged from 19 to 76 years, with the average of 43.9 years, and the course of diseases from 1 month to 16 years. 17 cases of lumbar interverteb ral disc prolapse were diagnosed between L2 and L3, 35 cases between L3 and L4, 140 cases between L4 and L5, and 116 cases between L5 and S1. 60 cases with two intervertebral disc prolapses at the same time, and 10 cases with three interve rtebral disc prolapses at the same time. A total of 458 intervertebral-dis c operations were conducted with PLDD. All the cases selected had been examined by CT or MRI, and their clinical symptoms and physical signs were in compliance with the diagnosis standards for prolapse of lumbar intervertebral disc. Results After PLDD operation, 268 cases were cured within 1 month with a cure rate of 70.90%; 259 cases were cured in 3 months with a cu re rate of 68.52%, 260 cases were cured in 6 months with a cure rate of 68 .25%. Stable results were found with curing satisfaction rate, effective rate and failure rate. Conclusion X-ray guided PLDD therapy is an ideal non-operative therapy for curing lumbar intervertebral disc prolap se with micro-trauma, little pain, quick recovery and good effect. PLDD has ac hieved encouraging effects both in its recent clinical outcome and long term eff ect as well.

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.

By the way of searching engines and finding website linkages, the author retrieved the domestic and foreign medical ethics information resources on internet,enumerated some main websites related to medical ethics, analyzed the present condition,and suggested that we should hasten the construction of medical ethics information resources on internet.

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.
