Objective To study the effect of down-regulation of E-cadherin on the invasive ability of tumor cells. Methods Human pancreatic carcinoma cell lines JHP-1, PANC-1, and MIA PaCa-2 were selected. The immunocytochemistry, Western blot and invasive-MTT assay were used to observe the expression and the contents of E-cadherin in the tumor cells. Results Immunocytochemistry showed that E-cadherin expression was on cell membrane. The expressions of E-cadherin were preserved in JHP-1, reduced in PANC-1, and showed negative in MIA PaCa-2. Western blot analysis showed that the protein content was the highest in JHP-1 and lowest in MIA PaCa-2. According to invasive MTT assay, the invasive ability of MIA PaCa-2 was the strongest, followed by PANC-1 and JHP-1 (P

Objective To establish a simple and stable model of orthotopic small intestinal transplantation(OIT) in rats.Methods The harvested en bloc segmental intestine consisted of donor abdominal aorta with superior mesenteric artery and portal vein.After in situ infusion with lactated Ringer′s solution,the graft was stored in 4℃ lactated Ringer′s solution.The segmental intestine transplantation was performed by end-to-side anastomosis of donor abdominal aorta to recipient abdominal aorta.The donor portal vein was anastomosed to the recipient left renal vein by "cuff anastomosis".The graft was anastomosed orthotopically by continuous(sutures).Results Sixteen intestine transplantations were,performed the average time for the arterial and(venous) anastomosis was 25?5 min and 4?1 min,respectively.Among the 16 recipient rats,13 survived more than 5 days.The average survival time was 10.35?2.84 days;the longest survival time was 21 days.Conclusions Graft harvesting,the technique of vascular and intestinal anastomosis and the(maintenance) of adequate blood volume are the key points for success of the operation.This successfully(established) model can serve as an excellent animal model for basic research of small intestinal trasplantation.

Objective To evaluate the feasibility,effectiveness and safety of Carto3 three-dimensional electrophysiological mapping system in guiding radiofrequency ablation (RFA) for paroxysmal supraventricular tachycardia (PSVT).Methods The clinical data of a total of 28 patients with PSVT (Carto group),who received RFA guided by Carto3 three-dimensional electrophysiological mapping system during the period from March 2015 to February 2016,were retrospectively collected.Other 36 parents with PSVT,who received fluoroscopy-guided RFA during the period from March 2014 to February 2015,were collected as control group.The X-ray irradiation time,success rate of operation,operation time,complication and recurrence rate were calculated and the results were compared between the two groups.Results The mean fluoroscopy time in Carto group was (2.6±2.3) min,which was significantly less than (15.8±9.5) min in the control group (P<0.001),and among them zero X-ray irradiation was obtained in 8 patients who had atrioventricular nodal reentrant tachycardia (AVNRT).The operation success rates of Carto group and the control group were 100% (28/28) and 94.4% (35/36) respectively (P>0.05).The operation time in Carto group and the control group was (162.7±34.4) min and (149.4±46.2) min respectively (P>0.05).In Carto group no any complications occurred,and in the control group one patient with AVNRT developed transient degree Ⅱ atrioventricular block during ablation process.All patients were followed up for 6 months,and no recurrence was observed in all patients of both groups.Conclusion For the treatment of PSVT,RFA guided by Carto3 three-dimensional electrophysiological mapping system is safe and effective,it can significantly reduce the X-ray irradiation time,even zero X-ray radiation in some AVNRT patients,meanwhile,this technique does not increase operation time and operation risk.

Objective To investigate the effect of β-elemene on SGC7901 gastric cancer cell line and the potential proteins involved. Methods Human SGC7901 gastric cancer cells were treated with different concentrations ofβ-elemene.Cell viability was assessed.A proteomic method,isobaric tags for relative and absolute quantitation (iTRAQ),was employed to detect the proteins altered by β-elemene.Protein expression was validated by Western blot.Results β-elemene inhibited the viability of SGC7901 gastric cancer cells in a dose-dependent manner.Altogether,147 upregulated proteins and 86 downregulated proteins were identified in response to β-elemene treatment in SGC7901 gastric cancer cell line.Among them,the expressions of p21-activated protein kinase-interacting protein 1 (PAK1IP1 ),Bcl-2-associated transcription factor 1 (BTF)and topoisomerase 2-alpha (TOPIIα)were validated by Western blot and the trends were consistent with iTRAQ results.Top pathways involved inβ-elemene treatment in SGC7901 gastric cancer cell line included ribosome signaling,peroxisome proliferator-activated receptors (PPARs)signaling pathway,regulation of actin cytoskeleton,phagosome,biosynthesis and metabolism of some amino acids.Conclusion Our results suggest a promising therapeutic role of β-elemene for gastric cancer.The differentially expressed proteins give us better insights into the potential mechanisms involved in gastric cancer treatment using β-elemene.
