Objective: Due to the high cost and complicated imaging interpretation of intravascular ultrasound (IVUS), we conducted a comparative study between AngioLight system and IVUS measurement of coronary diameter to explore the safety and efifcacy of AngioLight performance in experiment pigs.
Methods: There were 3 reference target points established in left anterior descending (LAD), left circumlfex (LCX) and right coronary arteries (RCA) in 3 Chinese mini-pigs. Each coronary branch had①target point, ②proximal target point, which was (10-15) mm up to target point,③distaltarget point, which was (10-15) mm down to target point. The coronary diameters were measured and compared by both IVUS and AngioLight system. Upon stent implantation, the diameters were measured again by both IVUS and AngioLight system at distaltarget point, stent edge of distal target point and proximal target point, stent edge of proximal target point respectively. And results comparison between AngioLight and IVUS were also compared.
Results: In 25 measurements, neither adverse complication nor death were occurred during the study. There were no significant statistical differences between IVUS real-time max diameter and AngioLight catheter max diameter measurements (2.57 ± 0.54) mm vs (2.70 ± 0.49) mm,P=0.09, as well as between IVUS analyzed max diameter and AngioLight catheter max diameter (2.68 ± 0.6) mm vs (2.59 ± 0.42) mm,P=0.37. In addition, good correlations were observed (r= 0.73,P<0.001) and (r= 0.67,P=0.001) respectively.
Conclusion: Angio Light system has good safety and correlation with IVUS for quantitative measurement of coronary diameter in experimental pigs.

OBJECTIVE To study the risk factors and clinical characteristics of nosocomial infection in senile patients with acute myelogenous leukemia who received chemotherapy.METHODS Ninety-one cases of senile patients with acute myelogenous leukemia received 304 times of chemotherapy with etiological examination,to analyze the relationship between nosocomial infection and absolute neutrophil count in peripheral blood,the cellularity of the marrow and chronic systemic disorder.RESULTS All indicators of senile patients with acute myelogenous leukemia were higher than those of younger patients(P0.05).CONCLUSIONS Age,different stage of chemotherapy,the neutrocytopenia level and prolongation,and hypocellularity of bone marrow are related to the nosocomial infection in senile patients with acute myelogenous leukemia,and the chronic systemic disorder is not a risk factor.

Objective To study the efficacy and safety of recombinant human thrombopoietin (rhTPO)in the treatment of thrombocytopenia induced by chemotherapy in elder patients with acute myeloid leukemia. Methods 20 elder patients with acute myeloid leukemia who got CR received two cycles of consolidation chemotherapy. In the first cycle of chemotherapy(control cycle), they were transfused with platelet suspensions when they developed severe thrombocytopenia; In the second cycle of chemotherapy (treatment cycle), they were given subcutaneous injection of rhTPO 1.0μg·kg-2·d-1 for 14 days or until platelet count≥ 80×109/L with the treatment above all when platelet count ≤50×109/L. The efficacy and safety were evaluated. Results The duration of Plt count<100×109/L in the treatment cycle and the control cycle was (23.1±4.5)d and (25.8±5.7) d (P<0.005); the duration of Plt count≤20×109/L in the treatment cycle and in the control cycle was (6.8±2.6) d and (11.7±3.2) d (P<0.005). The minimal Plt count of the treatment cycle and the control cycle were (13.2±4.4)×109/L and (12.2±3.1)×109/L (P＝0.0967) respectively, and the maximal Plt count after its recovery were (239.3±48.7)×109/L and (163.5±32.4)×109/L (P<0.005) respectively. Platelet transfusion was (22.8±6.8) U in the treatment group, it was significantly lower than that in the control group (30.0±6.3) U (P<0.05).The changes of hemoglobin content, white blood cell count, Urine routine, the function of liver and kidney, the function of blood coagulation after chemotherapy in both groups were no obvious(P ＝0.0872). Transient adverse reaction was observed in 5 patients (25 %). No thrombotic incident had occurred. Conclusion rhTPO can significantly accelerate PLT recovery, reduce the degree and duration of thrombocytopenia induced by chemotherapy, and reduce platelet transfusion in the treatment of consolidation chemotherapy for the elder patients with acute myeloid leukemia. It is safe and can be recommended to use widely.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.
