ABSTRACT
OBJECTIVE@#To investigate the therapeutic effect of carbon dioxide laser tonsillectomy.@*METHOD@#In this prospective, randomized study, One hundred and two patients were divided into laser group or control group. Patients of laser group were cured with carbon dioxide laser tonsillectomy, and the control group was cured with routine method. All operations are executed by one person. Observation index included operation time, hemorrhage in operation, ache after operation, inflammatory reaction of raw surface, repair time of raw surface, rehaemorrhagia and scar.@*RESULT@#Laser group had advantages of less operation time, less hemorrhage, less ache and less inflammatory reaction of raw surface. Laser group have hemorrhage in operation (7.2 +/- 2.1) ml, while control group have hemorrhage in operation (92.0 +/- 35.0) ml. Laser group have pseudomembrane early but desquamate late.@*CONCLUSION@#Carbon dioxide laser tonsillectomy is effective to relieve pain, inflammatory reaction and with less time, it's a safe, efficient and mini-trauma operation.

ABSTRACT
Objective To establish a chromogenic assay for blood-plasma collagenase Ⅳ in order to evaluation the reference range of collagenase Ⅳ in the plasma of healthy individuals.Methods The assay was based on measurement of terminal amino group with succinylated gelatin as substrates and TNBS as chromogenic reagent.The optical density of each reaction was determined at 405 nm using a Sunrise microplate reader.Chromatographic and detection conditions were optimized and performance of the methed was evaluated by recovery experiments and precision experiments.It was compared with ELISA.The levels of collagenase Ⅳ in 112 health persons'plasma were determined and the data were analyzed by SPSS statistical software.Results The whole determing time was within 1.5 h,the linear range of this method was 1.5-10.0 mg/L,and the minimum detection limit was 0.965 mg/L.They were well correlated with ELISA results (R~2=0.999 7,P＜0.01).The within-run CV was less than 3.16%and between-run CV was less than 9.81%.The 95%confidence interval of collagenase Ⅳ in healthy plasma was 33.38-49.80 mg/L.Conclusion This chromogenic assay for blood-plasma collagenase Ⅳ can be used for measurement of collagenase Ⅳ in blood-plasma and the reference range of collagenase Ⅳ in healthy plasma was established.
ABSTRACT
objective To establish a new method for isolation and identification of mixed erythrocytes with different blood groups from the patients following ABO-incompatible allogeneic haematopoietic stem cell transplantation(allo-HSCT),and investigate its application in post-transplantation survival erythrocytes.Methods The erythrocyte blood group antigens from the patiehts following ABO-incompatible allo-HSCT were agglutinated by the antibodies known.centrifuged at 800×g and 50×g to isolate agglutinated and unagglutinated erythrocytes respectively step by step.These erythrocytes collected were counted and identification respectively.Results The sensitivity,accuracy,recovery and reproducibility of the new method were 1%,100%,92.5%and 100%,respectively.The post-transplantation survival erythrocytes mixed with patient's erythrocytes from 18 patients following ABO-incompatible allo-HSCT were successfully isolated and identified by provided methods.It was the first time to identify the survival erythrocytes 11 th to 72 th day after allo-HSCT.The amount of the survival erythrocytes had been changing following post-transplantation periods.Conclusions The method can be widely employed in the isolation and identification of mixed erythrocytes with different blood groups.It provides reliable method to study the clinic significance of the changes of the survival erythroeytes from the patients following ABO-incompatible allo-HSCT.
ABSTRACT
Objective To investigate the effect of Ulinstatin(UTI) on oxygenation and gastric intramucosal pH in dogs with sepsis. Methods Sepsis was induced by intravenous infusion of lipopolysaccharide of E.coli.055:B5 to dogs,and the twenty dogs were divided into control group and ulinastatin group.Ulinastatin was administered in the ulinastatin group.The oxygen delivery(DO2),oxygen consumption(VO2), oxygen extraction(O2ER), plasma lactate levels and gastric intramucosal pH(pHi) were monitored. Results In early sepsis dogs,DO2,VO2,O2ER and plasma lactate levels increased significantly. Gastric intramucosal pH(pHi) decreased significantly. After the treatment with ulinastatin,DO2,VO2,O2ER and plasma lactate levels decreasd(P
ABSTRACT
Objective To investigate whether the biochemical function and morphology of stored outdated erythrocytes were able to be restored to normal levels.Methods The experiments were carried out with 4 groups of erythrocytes. Group 1 consists of post-rejuvenated erythrocytes, which were harvested by incubating twice washed stored erythrocytes on the 3 rd day after outdate at 37℃ for 1h, with a rejuvenating solution containing adenine 5mmol/L, inosine 100mmol/L, pyruvate 100mmol/L, phosphate 103mmol/L. Group 2 was pre-rejuvenate erythrocytes, obtained by washing stored erythrocytes on the 3rd day after outdate. Group 3 was saline control erythrocytes, which were incubated with 0.9% saline. Group 4 was freshly collected erythrocytes used as normal controls. ATP, 2, 3-DPG, morphology scores, MCV, osmotic fragility, and hemoglobin content of RBC in four groups were measured.Results The post-rejuvenate RBC ATP [(3.41?0.52)?mol/gHb] was significantly higher(P0.05) compared with fresh RBC [(3.45?0.51)?mol/gHb].The post-rejuvenate RBC 2,3-DPG [(14.08?3.10)?mol/gHb] was significantly higher(P0.05) compared with fresh RBC [(14.87?3.10)?mol/gHb].The post-rejuvenation morphology score(130.00?10.80) was significantly greater (P0.05) compared with fresh RBC (120.00?5.00). The post-rejuvenate mean corpuscular volume [(89.30? 7.20)fl] was significantly lower (P0.05). The hemoglobin shed in vesicles during rejuvenation was significantly greater than that in the saline control [(0.51?0.33)vs(0.20?0.18)mg/dl RBCs;P
