Objective To approach therapy of acute lymphoblastic leukemia(ALL) complicating acute respiratory distress syndrome (ARDS) in children.Methods The therapy of seven children diagnosed as ALL complicating ARDS was analyzed, who were treated by anti-infection, methyllprednisolone, ambroxol and constant positive airway pressure (CPAP) assisted ventilation.Results Six cases were recovery and one was death. The cure rate was 85.7%. Conclusion The cure rate is high, when employing combined therapy to treat ALL complicating ARDS.

1.0 mmol/L).The clinical side effects after medication circa were compared between two groups.Results There was no significant difference in myelosuppression,liver functional lesion,gastrointestinal tract reaction and infection in 2 groups.But following the increase of MTX blood drug level,the incidence rate of skin mucosa contamination,electrocardiographic abnormality,the cardiac creatase abnormity and nervous system symptoms significantly increased.Conclusions In the course of child ALL treatment with HD-MTX+CF,the side effects are common and individual difference is obvious.Specific treatment on individuals is suggested.J Appl Clin Pediatr,2006,21(3):170-171

Objective To develop new methods to cultivate, retrieve and purify mouse mesenchymal stem cells (mMSCs). Methods Bone marrow was collected from 2-month-old Kunming mice by flushing femurs and tibias with complete medium of DMEM-LG. Cells were plated in a Petri dish. After 24 hours, non-adherent cells were removed by two to three washes with PBS, adherent cells were further cultured in complete medium and retrieved by trypsinisation with 0.25% trypsin for 5 min at 37 ℃. The treated adherent cells were cultivated with 3?dilution for further generations. CD11b-negative cells were retrieved from the collected adherent cells of 3rd generation by using immunomagnetic microbeads, and continued to be cultured in complete medium. After the cultured cells were retrieved, their morphology and their ability of osteoblastic differentiation and adipocytic differentiation were examined. Results Most of mMSCs from 1st generation were of shuttle shape, some of irregular shape. After treatment with magnetic microbeads and several generations, mMSCs were of spindle, star and irregular shape. These cells were of rich cytoplasma, clear nucleolus, and grew in parallel or vortex. The cultured adherent cells from the first and subsequent generations had plenty of CD11b-positive blooding-making cells. After 20-day osteoblastic induction, mMSCs differentiated into bone cells, which showed orange phosphate in extracellular matrix by Alizarin red S staining. mMSCs could differentiate into lipocytes. The size of cells increased along with fat-developing induction period. These cells showed many orange fatty follicles with O Red Oil dyeing. Conclusion Pure mMSCs can not be retrieved by either adhering method or generation cultivation method separately. The combined methods of adhering, immunomagnetic microbeads, and serial subcultivation is effective in vitro in retrieve mMSCs.

Objective To investigate the effects of dibutylphthalate (DBP) on the proliferation and apoptosis of HL-60 leukemic cells and to study its mechanism to purge leukemic cells.Methods The effects of DBP on proliferation of HL-60 leukemic cells were measured by cell culture method. The effects on apoptosis were measured by the percentage of the apoptotic cells in morphology and of the DNA fragmentation and by DNA gel electrophoresis. The intracellular free Ca~(2+) concentration ([Ca~(2+)]i) of leukemic cells were measured by Fura-2AM method. The protein expressions of c-myc and bcl-2 genes of leukemic cells were measured by immunohistochemical assay.Results DBP could suppress the proliferation of HL-60 leukemic cells in a dose-dependent and time-dependent manner and induce them to die via apoptosis.It could elicit a intracellular Ca~(2+) redistribution and a potent extracellular calcium influx. It also down-regulated the protein expressions of c-myc and bcl-2 genes of HL-60 leukemic cells.Conclusion DBP can purge (HL-60) leukemic cells in vitro by increasing [Ca~(2+)]i of cells to initiate apoptosis and down-regulating bcl-2 and c-myc proto-gene expressions to promote cell apoptosis.

Objective To explore the effective method of treating childhood acute aplastic anemia(AAA) by overviewing the curative effect of therapeutic alliance to the children diagnosed as AAA with immunodepressants.Methods Retrospective analysis was performed on 13 patients diagnosed as AAA,who were treated by high dose of methyllprednisolone,antilymphocyte globulin,ciclosporin A,large dose of gamma globulin,granulocyte colony-stimulating factor and blood transfusion in 4 years.Results Among 13 cases,9 cases were healing well on the whole,one was relieved,one was improving,two were ineffective(one of them was dead).In 9 cases who were healing,WBC took(24.60?8.86) days to reach 4?10~9/L,hematoglobin took(152.22?68.88) days to reach normal and platelet took(125.55?55.86) days to reach 80?10~9/L.During the procedure of treating,infection appeared in 7 cases,the ALT and AST was high in 2 cases,hypoproteinemia and edema in 1 case,gross hematuria in 2 cases,gingival hyperplasia obviously and dedentition in 1 case.Conclusion Therapeutic alliance with immunodepressants to childhood AAA is a safe and effective method.

Obstructive sleep apnea-hypopnea syndrome(OSAHS) is a common sleep-related breathing disorder,which has a series of impact on the cardiovascular system.The dctection of some biochemical indicators plays an important role in predicting this kind of cardiovascular damage.The role of inflammatory predicting factors such as TNF-?,IL-6,CRP,IL-10,MMPs and ICAM-1 is reviewed in this paper.

Objective To investigate the benefits of long-term home noninvasive positive pressure ventilation(NIPPV) for patients with stable chronic obstructive pulmonary disease(COPD). Methods From 2006 to 2007,46 patients with chronic respiratory failure due to stable COPD receiving NIPPV in Croix Rousse Hospital were retrospectively analysed.The arterial blood gas analysis of before treatment,1,3,6,12,24 and 36 months after treatment were compared,and the lung function of before treatment,6,12,24 and 36 months after treatment were also compared. Results PaCO2 of 1,3,6,12,24 and 36 months after receiving NIPPV significantly decreased(P
