Objective To investigate the clinical significance of CA19-9 and CEA detection in the diagnosis of pancreatic carcinoma.Methods From January 2003 to November 2005,serum tumor markers(CA19-9 and CEA)in 44 patients with pancreatic carcinoma and 64 healthy volunteers were detected by radioimmunoassay.Results The levels of CA19-9 and CEA were markedly higher in the patients with pancreatic carcinoma than in healthy volunteers(P＜0.01).The sensitivity of combined detection of CA19-9 and CEA was much higher than any single detection.While the specificity of combined detection of CA19-9 and CEA had no statistical difference when compared to a single detection.The levels of CA19-9 and CEA in the Ⅰ+ⅡA stage patients were of no significant difference as compared with those in the patients of ⅡB+Ⅲ+Ⅳ stage,whereas the sensitivity of CA19-9 and CEA in the patients of ⅡB+Ⅲ+Ⅳ stage but much higher than in those of Ⅰ+ⅡA stage.Conclusion The serum concentrations of CA19-9 and CEA are closely related to pancreatic carcinoma with the invasion of mesenteric artery and lymphatic and distant organic metastasis.Combined detection of CA19-9 and CEA can improve the diagnosis of pancreatic carcinoma.

Objective To observe the protective effects of the mixture of ferulic acid (AF) and paeoniflorin on PC12 cells injury by FeSO4/H2O2 in vitro, and explorer its mechanism. Methods The cell injury model was established with FeSO4/H2O2 for 24 h. The process of the growth and morphology of the cells were observed under phase contrast microscope in vitro. The survival rate of the cells was determined by MTT method. The content of MDA and SOD activity was measured respectively by thiobarbituric acid and xanthine oxidase method. Results Compared with FeSO4/H2O2, the mixture of ferulic acid (AF) and paeoniflorin enhanced the PC12 cells survival rate and viability, reduced MDA content and increased SOD activity. Conclusion The mixture of 5～50 ?mol/L AF and 1～10 ?mol/L paeoniflorin exerted protective effects on PC12 cells injury induced by FeSO4/H2O2, which maybe related to free radical scavenging activity and lipid peroxidation process being inhibited.

Objective To investigate the effect of ulinastatin (UTI) on hepatic ischemia-reperfusion injury in rats. Methods Totally 24 adult Sprague-Dawley rats were randomly divided into 3 groups: sham-operated control group (SO group), ischemia-reperfusion group (I/R group) and ulinastatin group (UTI group). Liver in I/R group underwent 1 h of reperfasion after 30 min of ischemia. In UTI group, UTI (2×104 U/kg) was administered to rats 30 min before modeling. The levels of alanine aminotransferase, aspartate aminotransferase and tumor necrosis factor-alpha (TNF-α) in serum were measured and the levels of nitric oxide and malondialdehyde in liver were determined. The histological changes of liver were observed. Results The levels of alanine aminotransferase, aspartate aminotransferase and TNF-α in serum were significantly increased in I/R group compared with those in UTI group (P<0.05). The levels of nitric oxide and malondialdehyde in liver were significantly higher in I/R group than in UTI group (P<0.05).Histological examination of liver indicated that the damages were more severe in I/R group than in UTI group.Conclusion UTI has the ability to inhibit the production of TNF-α and oxyradical, and ameliorate microcirculatory dysfunction in rats with hepatic ischemia-reperfasion injury.

Objective To evaluate the effects and the side effects of three-dimensional conformal radiotherapy on recurrent cervical carcinoma with pelvic wall infiltration. Methods Twenty-one patients with recurrent cervical carcinoma infiltrating the pelvic wall were irradiated by three-dimensional conformal radiotherapy. The regimen was: total dose 30-52Gy,5-8.5Gy/f, 1f/2d. Results The rates of sciatic pain and leg edema relief response were 100 % and 61 % respectively. The CR+PR response rate was 71.4 %. The overall 1-, 2- and 3-year survival rates were 38 %, 14 % and 4 %. Conclusion Three-dimensional conformal radiotherapy is more effective than conventional radiotherapy and chemotherapy for recurrent cervical carcinoma infiltrating the pelvic wall. It doesn't increase the side-effects on the digestive system and the urinary system.

Objective To study the distribution of allogenic bone marrow-derived mesenchymal stem cells (BM-MSCs) on joints of collagen-induced arthritis (CIA) rats and to investigate their repair effects on joint damages. Methods Five Wistar rats were used for extraction of mesenchymal stem cells and 30 adult female Wistar rats were divided into 3 groups: the CIA rats group A (n=10), CIA rats group B (n=10) and normal rats control group C (n=10). BM-MSCs of Wistar rats were isolated, cultured in vitro routinely and the fourth passages was taken for identification of specific surface antigens by flow cytometry, then the cells were labeled with 5-bromodeoxyuridine (5-BrdU) in vitro. The models of CIA rats were established. 5-BrdU labeled BM-MSCs (1.0×107 cells/kg) were imfused from through tail vein to CIA rats group A and control group C. During the first 4 weeks after BM-MSCs transplantation, changes of general condition and left hind paw swelling were examined. At the fourth week, immunohistochemical examination of 5 -BrdU and osteoprotegerin (OPG) were performed to investigate BM-MSCs aggregation around the knee joints. The contribution of BM -MSCs to repairing of joint damages was identified. Comparisons between groups were performed by t-test. Results After BM-MSCs transplantation, left hindpaw swelling of group A were relieved compared with group B (P＜0.05) and the mobility of the joints was significantly improved. At the fourth week, much more implanted cells (5-BrdU positive cells.) were detected in the damaged knee joints than those in normal knee joints. The average grey scale values on synovium of knee joints in the CIA group A (85±9) was significantly lower than that of the normal group C (110±6, P＜0.05). At the same time, OPG expression was increased in damaged knee joints. The average grey scale values on synovium of knee joints in CIA group A (54±4) was significantly lower than that of the CIA group B (77±6, P＜0.05). Conclusion The transplanted allogeneic bone marrow mesenchy-mal stem cells can migrate to sites of damaged tissue in arthritis. They can prevent tissue damage and repair the damaged joints tissue by increasing OPG expression. This study has provided some evidence for developing effective therapy for rheumatoid arthritis.

ObjectiveTo study the effect of allo-human bone marrow mesenchymal stemcells (bMSCs) on the secretion of interleukin(IL)-1, tumor necrosis factor(TNF)-α and transforming grouth factor (TGF)-β of patients with rheumatoid arthritis (RA) in vitro. MethodsBMSCs were isolated from bone marrow of healthy volunteers and purified by density gradient centrifugation and cultured in vitro. The mononuclear cells from the peripheral blood of patients with RA and healthy controls were isolated respectively.bMSCs and mononuclear cells were co-cultured in vitro and the density of IL-1, TNF-α and TGF-β3 in the co-culture system were detected by ELISA. ANOVA and Pearson correlation were used for statistical analysis.ResultsMononuclear cells from peripheral blood of patients with RA were co-cultured with bMSCs for seven days. There were an decreased density ofIL-1[(38.4±0.5) vs(6.2±1.0) ng/L], TNF-α[(29.4±1.3) vs (4.6±1.2) ng/L]and an increased density of TGF-β[(2.6±1.0) vs (22.5±2.2) ng/L]in the co-culture system (P＜0.05). But on the other hand, for healthy volunteers there were no significant change in the density of IL1[(4.4±1.1) ng/L]and TNF-α[(5.0±1.7) ng/L]in the coculture group, as compared with the mononuclear cell group[(4.4±1.3) vs(5.3±1.7) ng/L](P＞0.05). There was an increased density of TGF-β in the coculture system[(4.8±1.4) vs(10.5±1.2) ng/L](P＜0.05). IL-1 was positively correlated to TNF-αt (r=0.896,P=0.000), TNF-β1 was nagative correlation with 1L-1 and TNF-α (r=-0.356,P=0.019; r=-0.380,P=0.000).ConclusionHuman bone marrow MSCs have modulatory effects on main cytokines of patients with RA in vitro. bMSCs could down-regulate the levels of IL-1 and TNF, but up-regulate the density of TGF-β. These immune-modulatory effects are not MHC restricted. The results of this study have provided evidence for the development of effective therapy for RA.

Objective To explore the impact of a“one-week”staged multivessel percutaneous coronary intervention (PCI) versus culprit-only PCI on deaths and major adverse cardiac events (MACE). Methods We retrospectively analyzed 447 patients with multivessel disease who experienced a ST-segment elevation myocardial infarction (STEMI) within 12 h before undergoing PCI between July 26, 2008 and Septem-ber 25, 2011. After completion of PCI in the infarct artery, 201 patients still in the hospital agreed to undergo PCI in non-infarct arteries with more than 70%stenosis for a“one-week”staged multivessel PCI. A total of 246 patients only received intervention for the culprit vessel. Follow-up ended on September 9, 2014. This study examined the differences in deaths from any cause (i.e., cardiac and noncardiac) and MACE between the two treatment groups. Results Compared to a culprit-only PCI treatment approach, the“one-week”staged multivessel PCI was strongly associated with greater benefits for 55-month all cause death [41 (16.7%) vs.13 (6.5%), P=0.004] and MACE [82 (33.3%) vs. 40 (19.9%), P=0.002] rates. In addition, there were significant differences in the number of myocardial infarctions [43 (17.5%) vs. 20 (10.0%), P=0.023], coronary-artery bypass grafting [CABG;20 (8.1%) vs. 6 (3.0%), P=0.021], and PCI [31 (12.6%) vs. 12 (6.0%), P=0.018]. Patients undergoing culprit-only PCI compared to“one-week”PCI had the same number of stent thrombosis events [7 (2.8%) vs. 3 (1.5%), P=0.522]. Conclusions Compared to a culprit-only PCI treatment approach,“one-week”staged multi-vessel PCI was a safe and effective selection for STEMI and multi-vessel PCI.

Objective To investigate the relationship between peritoneal macrophages (PMAs) and inflammatory reaction in a rat model of severe acute pancreatitis (SAP). Methods Sprague-Dawley rats were randomly divided into control group and SAP group. To induce SAP in rats, 40 g/L sodium taurocholate (0.1 mL/100 g) was injected into the pancreatic duct through retrograde exposure of pancreatic bile duct in hepatic porta. One-third of rats were sacrificed at 3, 6 or 12 h after modeling. PMAs were extracted, and incubated for 24 h in a humidified 5% carbon dioxide incubator. The expressions of tumor necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β) mRNA in PMAs were measured by semi-quantitative RT-PCR. The levels of TNF-α and IL-1β in culture medium and serum were evaluated.The histological changes of pancreas were examined. Rosults The expressions of TNF-α mRNA and IL-1β mRNA in PMAs were significantly higher in SAP group than in control group at each time point (P<0.01). The concentrations of TNF-α and IL-1β in culture medium and serum were significantly elevated in SAP group compared with control group (P<0.01). The histological analysis of pancreas indicated that the damage was more severe in SAP group than in cuntrol group (P<0.01). Conclusion PMAs secrete cytokines into pancreatitis-associated ascitic fluid, and this study demonstrates a correlation between SAP and the activation of PMAs.
