Objective To study the effect of lentivirus-mediated CCL5-RNAi on the biological behaviors of human breast cancer cells. Methods CCL5-specific siRNA gene was synthesized and cloned into the recombinant lentiviral vector, pGCSIL-GFP. Human high-metastatic breast cancer cells, MDA-MB-231, were infected by CCL5-siRNA recombinant lentivirus, which was set as KD group. Cells infected with CCL5-NC was as NC group, and cells cultured was as CON group. The expression of CCL5 mRNA and protein in MDA-MB-231 cells was detected by RT-PCR and western blot, respectively. Cell growth suppression and cell cycle was observed by MTT assay and fluorescence activated cell sorting (FACS). Colony formation and migration ability were determined by colony-rorming assay and Boyden chamber method. Results After infection of CCL5-siRNA recombinant lentivirus, the expression level of CCL5 mRNA and protein in MDA-MB-231 cells as well as the colony formation and migration ability decreased significantly, but cell's proliferation was not affected obviously. Compared with MDA-MB-231 (0.88± 0.15) and MDA-MB-231/CCL5-NC (1.00±0.07) cells, the expression of CCL5 mRNA in MDA-MB-231/ CCL5-siRNA decreased to 0.18±0.03, P<0.01. Compared with MDA-MB-231/CCL5-NC (1.82±0.18) cells, the expression of CCL5 protein in MDA-MB-231/CCL5-siRNA decreased to 0.33±0.13, P <0.01. Colony-forming assay and Boyden chamber method showed that the colony formation and migration ability of MDA-MB-231/CCL5-siRNA decreased markedly (P<0.05). The clone count in KD group was (0.33± 0.10), which was a significant decrease from (0.97±0.09) (NC group) and (1.04±0.07) (CON group), P<0.05. The number of cells that migrated through the chamber membrane of KD group (38± 15) was less than that of NC group (77±11, P <0.05) and CON group (69±9, P <0.05). However, MTT assay and FACS revealed that the proliferation of MDA-MB-231/CCL5-siRNA was not different from MDA-MB-231/CCL5-NC and MDA-MB-231 (P>0.05), the proliferation index (PI) of group KD, NC and CON were (0.48±0.02), (0.44±0.05) and (0.47±0.02) respectively. The difference was not statistically significant by multiple comparison (P>0.05). Conclusion CCL5-specific siRNA can specifically suppress the colony formation and migration of human high-matastatic breast cancer cells.

Objective To evaluate the clinical and pathological characteristics and risk factors of the prognosis of Cardia cancer.Methods Clinical data of 52 cases of cardiac cancer patients who were treated by surgery and follow-up data were collected from June 2009 to August 2011.Factors influencing the prognosis of the patients were analyzed by univariate and multivariate analysis.Results The survival rates in 1,2,3years were 73％,54％,46％.Single factor analysis showed that there was a significant correlation between T stage,N stage,TNM stage,classification Siewert,MSLN and venous invasion.Stepwise Cox proportional hazard model showed that T stage,N stage and MSLN were independent risk factors.Peritoneal and liver were the main way of recurrence and metastasis.Peritoneal metastasis was related to T stage and lymph node invasion,while the liver metastasis was related to MSLN.The survival curves of patients with Kaplan-Meier showed that the survival period of patients with liver metastasis and peritoneal metastasis was significantly shortened.Conclusion Standardization of lymph node cleaning is a key factor affecting prognosis,D2 surgery should be an operation standard in cardia cancer.

Objective To retrospectively analyze the influence of perioperatively transfusing different ratios of fresh frozen plasma (FFP) to red blood cell (RBC) on prognosis of patients receiving massive transfusion.Methods From January 2010 to September 2012,139 surgical patients with transfusion of ≥ 10 RBC units within 24 hours were included in the study.Patients were categorised into three groups based on the FFP ∶ RBC scale:high scale group (FFP ∶ RBC ＞ 1 ∶ 1,n =19),middle scale group (FFP ∶ RBC =1 ∶ 2-1 ∶ 1,n =43) and low scale group (FFP ∶ RBC ＜ 1 ∶ 2,n =77).Comparison among the groups was made in aspects of transfusion of different blood products in hospital,blood routine index before and after massive transfusion,blood coagulation index,electrolyte index,hospital stay,ICU stay,cure rate and mortality.Results FFP transfusion was the most in high scale group (2 600 ± 1 582) ml,followed by (1 390 ± 1 043) ml in middle scale group and (318 ± 342) ml in low scale group (P ＜0.05).Platelet (PLT) transfusion was more in high scale group (0-1.4 units) and middle scale group (0-1.0 units) compared with that in low scale group (0-0.0 units,P ＜ 0.05).Volume of RBC and cryoprecipitate transfused revealed no significant differences among the groups (P ＞ 0.05).Before blood transfusion prothrombin time (PT) [(20.2 ± 10.7) s] and activated partial thromboplastin time (APTT) [(57.2±45.8) s] in middle scale group were significantly prolonged than those in high scale group [(14.3 ±4.4) s and (35.3 ± 10.0) s] and low scale group[(12.5 ± 1.7) s and (31.5 ± 5.9) s] (P ＜ 0.05),but the differences were insignificant in indices of hemoglobin (Hb),PLT,international normalized ratio (INR),K +,and Ca2 + (P ＞ 0.05).After blood transfusion Hb [(106.8 ± 31.7) g/L] and Ca2+[(1.99 ± 0.24)mmol/L] in low scale group were higher than these in middle scale group [(82.5 ± 32.2) g/L and (1.76 ± 0.38) mmol/L] and in high scale group [(91.3 ± 19.1) g/L and (1.96 ±0.25) mmol/L] (P ＜0.05),but there were no significant differences in PLT,PT,INR,APTT and K+(P ＞ 0.05).Moreover,hospital stay,ICU stay,cure rate and mortality were not differed significantly among the groups (P ＞ 0.05).Conclusion For massive transfusion patients,transfusion of FFP and RBC at a 1 ∶ 2 to 1 ∶ 1 ratio is beneficial to preventing coagulation dysfunction and reducing plasma total infusion volume,and exerts no effect on the prognosis.

Objective To investigate the optimal dose of apocynin to protect severe acute pancreatitis (SAP) and SAP caused intestinal injury in rats. Methods A total of 53 SPF male Wistar rats were randomly allocated into five groups:sham operation group (SO group, n=10), SAP group (n=12), low-dose apocynin group (25 mg/kg,n=11), medium-dose apocynin group (50 mg/kg, n=10) and high-dose apocynin group (100 mg/kg,n=10). SAP model was prepared by retrograde infusing 5%sodium taurocholate (1 mL/kg) into biliopancreatic duct of rat. At thirty minutes before modeling, apocynin was injected into rat to intervention. The survival condition was recorded at 12 h after modeling, and blood samples were obtained for detecting serum amylase (AMY), alanine aminotransferase (ALT) and creatinine (Cr). Pancreatic and ileal tissue samples were obtained for HE staining and pathological examination. Results Two rats died in SAP group and one died in low-dose apocynin group. The quantity of ascites, the levels of AMY, ALT, Cr and pancreatic and intestinal pathologic scores were significantly increased in SAP group than those in SO group (P<0.05). Except the levels of Cr and intestinal pathologic score, there was no significant difference between low-dose apocynin group and SAP group. The quantity of ascites ascites, levels of AMY, Cr and pancreatic and intestinal pathologic scores were significantly lower in medium-dose and high-dose apocynin groups than those in SAP group (P<0.05). The levels of ALT and Cr were significantly higher in high-dose apocynin group than those of medium-dose apocynin group (P<0.05). Conclusion Apocynin improves SAP symptoms and reduces SAP caused intestinal injury in rats, which may be related to the inhibition of NOX activity, and 50 mg/kg of apocynin is the optimal dose.

Objective: To investigate the influence of lidocaine on systemic inflammation in the perioperative ventricular septal defect (VSD). Methods: Twenty patients, scheduled for ventricular septal defect were randomly divided into 2 groups: lidocaine and control groups. Before rebeat lidocaine 1 mg/kg was given.The venous blood samples were obtained from the central venous at the following points: after induction of anesthesia and before cardiopulmonary bypass(CPB,T1),1 h after CPB(T2),2 h after CPB(T3), and 4 h after CPB(T4). IL-6 and IL-8 were determined by radio-immunoassay. Results: Compared with those at T1, the levels of white blood cells,polymorphonuclear neutrophils,IL-6 and IL-8 increased significantly from T2 to T4 in both groups. IL-6 and IL-8 levels reached the peak at T2. Compared with those in control groups, IL-6 level decreased obviously in lidocaine group from T2 to T4, but IL-8 level remained unchanged significantly. Conclusion: Under CPB and VSD repair the systemic inflammation is obvious, reaches the peak 30 min after CPB and persists to 4 h after CPB. Perioperative administration of lidocaine is effective against the inflammation.
