Objective To investigate the anti-migratory and anti-invasive effect of somatostatin receptor type 2(SSTR2) gene transfection mediated by adenovirus in human pancreatic carcinoma cell and the mechanisms involved in this effect.Methods The full length human SSTR2 cDNA was introduced into pancreatic cancer cell line BXPC-3 by adenovirus-mediated transfection,and stable expression of RNA and protein of SSTR2 were detected by RT-PCR and Westen-blot.The Matrigel coated Transwell was used to detect the migratory and invasive ability of SSTR2expressing cells,Adv-GFP control cells and mock control cells.Furthermore,the expressions of matrix metalloproteinase-2(MMP-2) and tissue inhibitor of metalloproteinase-2(TIMP-2) were detected by RT-PCR method in these cells.Results The stable expression of SSTR2 was detected in BXPC-3 cells transfected by Adv-GFP-SSTR2.A dramatic decrease of BXPC-3 expressing SSTR2 cell(migrated) through a Matrigel-coated filter was observed,as compared with Adv-GFP control cells and mock control cells(P

Objective To study the effect of perioperative psychological nursing on living-related liver transplantation. Methods The following measures were adopted according to the donors' concrete condition: using nursing procedure in holistic nursing, to assess and determine the main problems in perioperative period, nurses mastered psychological nursing knowledge and skills in individualized psychological nursing, giving pertinent and individualized health education to patients in accordance with their psychological problems during the perioperative period. Results The donors could face the operation with good psychological state after being given fully-integrated and whole-system psychological nursing. Conclusions Psychological nursing is important for living-related liver transplantation during the perioperative period.

Objective To evaluate living-related liver transplantation (LRLT) for the treatment of Wilson′s disease. MethodsBetween Jan. 2001 and Oct. 2003,LRLT was performed in 20 patients (mean age 11.1 years) of late staged Wilson′s disease. Among them emergency transplantation was performed in 3 patients. Donor livers were all from patient′s parents. ResultsSurgery was successful in all donors and recipients, liver function test and serum ceruloplasmin reached normal level one month after transplantation. One patient died of severe rejection. Discharged patients were followed up from 2～33 months (mean 18.9 months). [WT5”HZ]ConclusionsLiving related liver transplantation is an effective treatment for Wilson′s disease complicated with hepatic dysfunction.

Objective To explore the expression and clinical significance of EphA2 and E-cadherin in (pancreatic) cancer tissue and cells.Methods The expression of EphA2 and E-cadherin in 56 pancreatic(carcinomas) and 23 adjacent noncancer tissues were studied by immunohistochemistry,and their relationship to clinicopathological characteristics were analyzed.RT-PCR was performed to explore the expression of EphA2,BXPC-3,PC-3 and PANC-1 in pancreatic carcinoma cell lines.Results In pancreatic carcinomas tissuse showed increased EphA2 expression and reduced E-cad expression which compared with adjacent noncancer tissues.The expression level of EphA2 had a significant positive relationship with tumor differentiation degree,lymphatic metastasis and clinical stage.However,the expression level of E-cadherin had negative relationship with both the tumor clinical stage and lymphatic invasion.Furthermore,a significant negative relationship(between) the expression of EphA2 and E-cadherin was observed.The expressions of EphA2 were higher in high-invasive cell lines PXPC-3 and Panc-1 than in low-invasive cell line PC-3.Conclusions The(expression) and/or abnormal function of EphA2 and E-cadherin may together be involved in the development and progression of pancreatic cancer;the combined measurement of these two proteins may be useful for(determination) of metastatic potency of pancreatic carcinoma.

Objective To observe the effect of antisense hypoxia inducible factor-1?(HIF-1?) on (chemosensitivity) of human pancreatic cancer cell line BxPC-3 under hypoxia. Methods BxPC-3 cells were divided into 3 groups:(1)BxPC-3 cells were non-transfected with antisense HIF-1? plasmid and exposed to 0.5% O_2 for 4hr(hypoxia control);(2)normoxic BxPC-3 cells were non-transfected with antisense(HIF-1?) plasmid(normoxia control);(3)BxPC-3 cells were transfected with antisense HIF-1? plasmid and exposed to 0.5% O_2 for 4hr(experimental group).Expression of HIF-1? and survivin was detected by RT-PCR and Western Blot.Growth inhibition rates and apoptosis rates of BxPC-3 cells under different(dosages) of chemotherapeutic agents(5-fluorouracil,doxorubicin and gemcitabine) were measured by MTT(colorimetric) assay and flow cytometry (FCM).Results Expression of HIF-1? was obviously down-regulated and at the same time susvivin expression was markedly down-regulated in experimental group(P

AIM:To investigate the roles of maspin in the biological behaviors of non-small-cell lung cancer A549 cells.METHODS:Full-length coding region of maspin was amplified by PCR from human normal breast tissue and cloned into MSCV vector .Virus supernatants was produced by Phoenix A packaging system , and target cell line was infec-ted with the virus supernatants .The transfected cells were screened with puromycin .The cell line with maspin over-expres-sion was identified by real-time PCR and Western blot.Cell growth, migration and invasion were investigated by xCelli-gence system .RESULTS:Maspin over-expression vector was successfully constructed .The cell line with maspin over-ex-pression was established .No difference of the growth between A 549-control cells and A549-maspin cells was observed .The migration and invasion were quite different between A 549-control cells and A549-maspin cells.The expression level of inte-grin β1 in A549-maspin cells was decreased compared with A 549-control cells .CONCLUSION:Maspin has no effect on the growth of A549 cells.Maspin suppresses the migration and invasion of A 549 cells, in which integrin β1 is involved.

AIM: To establish quality standard for Myricetin Dispersible Tablets. METHODS: Myricetin Dispersible Tablets were identified by UV and IR,and the content of myricetin in the tablets was determined by HPLC. RESULTS: The UV and IR spectra of Myricetin Dispersible Tablets were similar with those of myricetin.The linear range of myricetin was within the range of 0.071-0.165 mg/mL(r=(1.000 0)).The average recovery was 98.55%(n=6),and the RSD was 1.92%. CONCLUSION: The quality standard developed can be used for the quality control of Myricetin Dispersible Tablets.
