OBJECTIVE:To study the status and characteristics of the adverse drug reactions(ADR) presented in our hospital.METHODS:A total of 393 ADR cases collected during the period 2003～2007 in our hospital were analyzed statistically regarding the general status of the patients,route of administration,drug variety,the types of lesions and the clinical manifestations etc.RESULTS:Of the 393 ADR cases,the aged people(≥61 a) showed a highest incidence at 21.88%, 83.71%were induced by intravenous infusion,72.26%were induced by anti- infective drugs,lesions of skin and the appendants were the major type of ADR,accounting for 39.94%,and there were only 36 serious eases,accounting for 9.16%. CONCLUSION:ADR reporting and monitoring should be strengthened in hospital.Making full use of hospital ADR infor mation can facilitate rational drug use and improve clinical rational drug use level.

Objective To assess the clinical value of microguidewire looping technique in superselective catheterization of the acute angled artery. Methods Manipulating the microguide wire into a U shaped loop and simultaneus withdrawal of the microguidewire and microcatheter was performed when the tip of the microguidewire simultaneous got into the target artery and following by slowly and simultaneously withdrawing the microguidewire and microcatheter until the tip of the microguidewire entering into the target artery for a certain length and finally pushed the microcatheter into the target artery slowly. Results Eighteen out of 21 patients with acute angled target artery were successfully catheterized through this approach with technical success rate of 86%, without any complications. Conclusions Microguidewire looping technique is a feasible method for superselective catheterization of the acute angled artery when the routine approach failed.

Results:All catheters were inserted smoothly and its tips lay in suitable sites.128 pieces of catheter were pulled out after finished infusion. Conclusions:A right method of insertion and management is in favor for the use of a central venous catheter.

The cases were randomly divided into 2 groups,each32 cases.The results were:for the Chinese druggroup.13 cases were markedly effective,15 Cases withrather good effect,2 cases improved.2 cases ineffec-tive.For the control group,the figures were 5,13,11,3 respectively.The total effective rate was similar forthe 2 groups,but the markedly effective rate for theformer is higher thanthe latter (P

Objective:To investigate whether VLA-5 and VLA-6 are involved in facilitating en-dothelium-oriented transmigration of hematopoietic stem/progenitor cells. Methods:Purified hu-man CD34+ cells were subject to ex vivo transmigration assay and blocking experiments throughtranswell filter inserts coated with human umbilical vein endothelial cells (HUVECs). Four-colorfluorescence-activated cell sorting (FACS) analysis was applied to detect the expression profilesof adhesion molecules and chemokine receptor CXCR-4 on CD34bright cells. Results:Stromal cell-derived factor (SDF)-1-induced transmigrations of both mobilized peripheral blood (mPB)-(56.6±20. 1)% and bone marrow (BM)- (15. 6±1. 8)% derived CD34+ cells were significantlyfacilitated through HUVECs-coated transwell filter insters compared with noncoated ones, whichwere efficiently blocked by preincubation of CD34+ cells with neutralizing antibodies to VLA-5,or VLA-6, or both of them; meanwhile the proportions of migrating CD34+ cells through bothHUVECs-coated and noncoated transwell filter inserts in BM were significantly lower than thosein mPB; the different percentages of migrating CD34+ cells between in mPB and BM were corre-lated with their variable expressions of VLA-5 and VLA-6, but not for VLA-4 or chemokine re-ceptor CXCR-4. Conclusion:Facilitating HS/PCs transmigrations through HUVECs are involvedin both VLA-5 and VLA-6.

Objective To investigate the effect of immediately lymphatic reconstruction (LR) after heterotopic small bowel transplantation on pharmacokinetics (absorption and transportation) of FK506. Methods Male Brown-Norway (BN) and Lewis (LEW) rats were divided to two groups. Group A: BN→LEW+LR+FK506 ( n =12); Group B: BN→LEW+FK506 ( n =12). FK506 at a dose of 5?mg/kg per day was taken through stoma. At 1, 4, 7 and 14 postoperative day (POD), venous blood 0.5?ml was obtained on the 1.2 , 2 and 3?h after administration of FK506. Whole blood concentration of FK506 was analyzed by microparticle enzyme immunoassay and a kit of monoclone antibody. Results At the every phase of early period after transplantation (1, 4, 7 POD), the levels of FK506 in plasma were significantly higher in group A than in group B ( P

Objective To investigate the protective effects of epidermal growth factor (EGF) on pancreas of rats with acute pancreatitis(AP). Methods Seventy-two male Sprague-Dawley rats were randomly divided into 3 groups: Control group, AP group and AP-EGF group. Subcutaneously injection of EGF (0.1 ?g/g) were given to animals in the AP-EGF group after the establishment of the model of AP. The other two groups of animals received the same volume of saline. At 6 h, 12 h and 24 h after induction of AP, 8 animals in each group were sacrificed respectively, 4 ml of blood sample was withdrawn from heart,2 ml for the analysis of amylase activity and 2 ml for MDA content in serum. Ascites was sucked with dry gauzes and was weighed thereafter. Changes of pancreas morphology were evaluated at every time point. The same part of pancreas was removed for measurement of MDA content, apoptotic index (AI) and histologic changes. Results Histologic injury of the animals in the AP-EGF group was milder than that in the AP group. Ascites weight in the AP-EGF group decreased significantly compared with that in the AP group at 12 h and 24 h 〔(4.53?1.29) g vs (6.58?1.47) g, (7.64?1.85) g vs (11.96?2.13) g,P

Objective To investigate the expression of CD2 in peripheral blood T lymphocytes in acute rejection after small bowel transplantation (SBT) in rats.Methods Three groups were set up: Group A (n=18), receiving sham operation and feeding of common feedstuff; Group B (n=18) receiving SD rat to SD rat iso-series SBT and the treatment of routine liquid infusion and antibiotics after operation; Group C (n=18) receiving SD rat to Wistar rat taniso-series SBT and the same post- operation treatments as in group B. Samples of grafts and peripheral blood in the three groups were collected on the day 3, 5 and 7 respectively after SBT for detection of flow cytometry. The intestinal grafts were obtained for pathological examination.Results The survival time of rats in group C, group B and group A was 7.0? 2.1, 33.3? 2.3 and more than 90 days, respectively. There was significant difference between group C and groups A, B (P

Objective To investigate the protective mechanism of ischemic preconditioning on ischemic/reperfusion injury after pancreas transplantation in rats.Methods The model of diabetic SD rat was established. Twenty-four diabetic SD rats were randomly assigned to ischemic/reperfusion group (I/R group, n=6) and ischemic preconditioning group (IPC group, n=18). The rats in group IPC were averagely assigned to 3 sub-groups: group IPC_ 1 (5 min ischemic and 5 min reperfusion), IPC_ 2 (5 min ischemic and 5 min reperfusion twice) and IPC_ 3 (5 min ischemic and 5 min reperfusion thrice). Six normal SD rats whose abdomen was opened only served as control group, and they did not receive pancreas transplantation. I/R group and IPC group received pancreas transplantation. The superoxide dismutase (SOD) and myeloperoxidase (MPO) activity of grafts were monitored 2 h after reperfusion, the apoptotic cells in grafts were observed by TUNEL method, and the expression of Bcl-2 and Bax gene of the grafts was detected by Western blot.Results As compared with I/R group, the SIOD activity and the expression of Bcl-2 gene of grafts were significantly increased, while MPO activity, apoptotic index and the expression of the Bax gene in the grafts were markedly reduced in IPC group (P
