Methods 65 patients with ANVUGIB were randomly divided into group of titanium clips(31 cases) and group of injection combined with titanium clips(34 cases) for treatment of bleeding. The rate of curative effect of hemostatic and rehaemorrhagia was compared. Results All the patients of the two groups were succeed at the first time hematischesis, the hemostatic rates were all 100%. The titanium clips group has 6 cases rebleeding,and the rehaemorrhagia rate was 19.4% ,the injection combined with titanium clips group has 1 case rebleeding, and the rehaemorrhagia rate was 2. 9%. There was significant difference between the two groups. Conclusions The curative effect of injection with titanium clips was reliable, and was superior to treatment with titanium clips alone.

ObjectiveTo investigate the levels of serum interleukin -17(1L-17) and tumor necrosis factor -alpha( TNF- α ) and synovium pathological changes in patients with rheumatoid arthritis ( RA ) and its clinical significance.MethodsThe levels of serum IL-17 and TNF- α in 50 patients with active phase of RA ( active phase of RA group),50 patients with stable phase of RA ( stable phase of RA group ) and 50 normal controls (NC group) were measured by enzyme-linked immunospecific assay(ELISA),and the synovium was detected by pathological examination.ResultsThe levels of serum IL- 17 and TNF- α in active phase of RA group [(42.60 ± 11.30),( 113.20 ± 13.11 ) mg/L]were significantly higher than those in stable phase of RA group [( 19.60 ± 5.75),( 14.50 ± 5.33) mg/L]and NC group [(7.40 ± 3.32),( 10.90 ± 2.24 ) mg/L](P ＜0.01 ),the level of serum IL-17 in stable phase of RA group was significantly higher than that in NC group ( P ＜ 0.05),but the level of TNF- α had no significant difference between stable phase of RA group and NC group ( P ＞ 0.05).The synovium was significantly different between RA patients and NC group.Conclusion IL-17 and TNF-α are more sensitive index for detecting the activity of RA and may play important rolesinmonitoring the therapeutic effects and prognosis of RA.

Objective To investigate the effects and mechanisms of bone marrow mesenchymal stem cells (BMSCs) on pancreatic fibrosis in rats of chronic pancreatitis. Methods Thirty healthy male SD rats were randomly divided into three groups:control group, model group and transplanted group (n=10 for each group). Chronic pancratitis rat model was induced by retrograde injection of oleic acid into the biliopancreatic duct. The sham operation group was treated only with solvent. Transplanted group was given BMSCs through caudal vein injection at 1 week and 5 weeks after the model induction. All rats were weighed at 1 week, 4 weeks and 8 weeks in three groups. After 8-week feeding,pancreatic tissues were harvested for HE and picric-sirius staining. The contents of transforming growth factorβ1 (TGF-β1), typeⅠcollagen and typeⅢcollagen were detcted by using ELISA. Results Compared with the control group, the weights of rats were decreased at 4 weeks and 8 weeks in model group and transplantated group (P<0.05). There were no significant differences in body weights between model group and transplantated group (P>0.05). The pancreatic fibrosis score and pathological injury were ameliorated signicantly in transplanted group. The contents of TGF-β1, typeⅠcollagen and typeⅢcollagen in pancreas were increased in model group than those of control group and transplanted group (P<0.05). Conclusion BMSCs transplantation can reduce the collagen secretion and reduce the degree of pancreatic fibrosis in rats with chronic pancreatitis, which may be related to the inhibition of the release of TGF-β1.

Objective To determine the difference between target and measured concentration of remifentanil given by target-controlled infusion (TCI) and evaluate the performance of a new type Ⅰ TCI system for Chinese. Methods Thirty-six ASA Ⅰ or Ⅱ patients aged 40-60 yr weighing 50-70 kg undergoing elective lung resection were randomly divided into 2 groups according to target remifentanil concentration: group Ⅰ 6 ng ? ml-1 and group Ⅱ 8 ng?ml-1. The patients were premedicated with intramuscular midazolam 0.05 mg?kg-1 and atropine 0.5 mg. Anesthesia was induced with remifentanil and propofol both given by TCI. The target concentration of propofol (effect-site concentration) was set at 3 ?g?ml-1 and remifentanil (plasma concentration) at 6 or 8 ng? ml-1. When the patients lost consciousness, vecuronium 0.1 mg?kg-1 was given i. v. to facilitate intubation. The patients were mechanically ventilated and PETCO2 was maintained at 30-40 mm Hg. Anesthesia was maintained with TCI of propofol and remifentanil and intermittent i. v. boluses of vecuronium. Target plasma concentration of remifentanil remained unchanged during anesthesia. BIS value was maintained at 45-55 by modifying target propofol concentration. Arterial blood samples were taken before and 5, 10, 20, 40, 60, 90 and 120 min after TCI remifentanil was started for determination of blood remifentanil concentration by high performance liquid chromatography.The performance error (PE) was determined for each measured blood remifentanil concentration. The performance in the population was determined by median absolute performance error (MDAPE), median performance error (MDPE) and the wobble (the median absolute deviation of each PE from the MDPE). Results The measured concentrations (Cm) of remifentanil were significantly lower than the target plasma concentration (Cp) at5, 10, 20 min of TCI in both groups ( P
