Journal of Chongqing Medical University 1986;0(02):-
Objective:To observe the effect of autologous peripheral blood stem cells transplantation (APBSCT) on neutropenia and thrombocytopenia when tandem transfusion of stem cells is given.Methods:4 patients with hematological disease were mobilized with Cy+AraC+G-CSF before peripheral blood stem cells(PBSC) were collected.Peripheral blood stem cells transfusion were on 0 day and 3rd day after conditioning regimens.Results:The sufficient number of CD34+ cells could be collected.Neutropenia lasted 5-12days,while severe thrombocytopenia(BPC≤20?10 9/L)lasted only 3-4 days.Conclusion:APBSCT with tandem transfusion of stem cells result in shortening period of neutropenia and thrombocytopenia,less occurrence of neutropenic fever and severe bleeding,and reduction of cost.

Allogeneic stem cell transplantation is the only treatment which may cure multiple myeloma (MM).The high transplantation related mortality (TRM) limits the wide clinical application of myeloablative allogeneic stem cell transplantation.Non-myeloablative allogeneic stem cell transplantation can reduce the TRM,but the risk of relapse and progress of the disease may get increased. Autononmyeloablative allogeneic stem cell tandem transplantation can reduce both the TRM and the relapse and progress of the disease. At present,there exist many new methods which may improve the effect of allogeneic stem cell transplantation for MM in clinical.

Objective To prepare liposome-entrapped mitoxantrone (LEM)-GM-CSF and observe the cytotoxicity of HL-60/ADM cells treated with LEM-GM-CSF, LEM and dihydroxyanthraquinone (DHAQ) in vitro. Methods LEM was prepared by reverse phase evaporation (REV). High speed centrifugation was applied to separate LEM and dissociate DHAQ. Colorimetry was employed to determine encapsulation efficiency. The liposome structure and particle size were determined by transmission electron microscopy. GM-CSF was coupled to LEM by glutaraldehyde method. UV-spectrophotometric analysis was applied to measure the coupled efficiency. Flow cytometry was applied to determine the immunoconjugate retained efficiency. The cytotoxicity of HL60/ADM cells and interdiction efficiency of GM-CSF were investigated by MTT test. Results The encapsulation efficiency of LEM was 80%. Most liposomes were monolayer, and the particle size was 170-220 nm. Its coupled efficiency with GM-CSF was 42.3%, and the immunoconjugate retained efficiency was 74.6%. All LEM-GM-CSF, LEM and DHAQ had cytotoxicity on HL60/ADM, their cytotoxic power in decrement sequence: LEM-GM-CSF, LEM, DHAQ. After treated with LEM-GM-CSF, LEM and DHAQ for 24 h, the IC50 of HL-60/ADM was 8.73, 12.42, 27.31 ?g/ml respectively and for 48 h the IC50 were 0.62, 8.25, 12.44 ?g/ml. The inhibition rate increased in a dose-dependent manner. Conclusion The encapsulation efficiency, the coupled efficiency and the immunoconjugate retained efficiency of LEM-GM-CSF prepared by our method were satisfying. LEM-GM-CSF representing anti-leukaemia efficiency in vitro had cytotoxicity on HL60/ADM cells.

Objective To study the application value of ultrasound(US) examination for evaluating the knee joint status in the patients with hemophilia.Methods The US examination data of 44 patients (70 knee joints) with hemophilia were collected,among them 11 cases aged below 18 years old,16 knee joints completed the MRI examination,meanwhile the knee joint health status was evaluated by adopting the 2.1 version of hemophilia joint health assessment (HJHS) form.Then the correlation between the US score with the age and bleeding times and the relation between MRI score with HJHS score were analyzed.Results The severity of hemophilia arthropathy had no obvious correlation with hemophilia severity (F=0.013,P =0.987).With the age increase and bleeding frequency increase,the knee joint lesion was aggravated.The detection of early synovial thickening and cartilage change in arthropathy had no obvious difference between US and MRI examinations(P>0.05);the obvious correlation existed among US score,MRI score and HJHS (P<0.05).Conclusion US has an important significance for the early diagnosis of hemophilic arthropathy.
