Myelodysplastic syndrome (MDS) is a group of clonal diseases originating from hematopoietic stem/progenitor cells with high risk of transformation to acute myeloid leukemia (AML).Due to the lack of effective treatment after transformation into AML and the poor prognosis, now the bone marrow transplantation is the only way to cure this disease, but only a few of patients are suitable for transplantation.So the study on the mechanism of transformation of MDS to AML is important for development of effective drugs are.This paper presents a review of the latest update on mechanism of transformation of MDS to AML.

In order to improve integrative management of medical equipment,effective measures are taken in equipment purchase,use,maintenance,scrapping and scrappage disposal,which can bring the limited medical equipment resource into full play.

Objective: High tibial osteotomy treated medial compartment serious osteoarthritis of the knee with varus deformity,and relieving arthritic pain,correcting deformity and normal femoraltibial axial alignment.Methods:From May 1992 to February 1998,18 cases(21 knees) were operated on,We chose fit patients and planed osteotomy angle.Results:All cases were followed up for an average 3.2 years,according to Coventry's rating system,81% of the whole series had a good or excellent results.Conclusion:It increases the medial joint space width and corrects femoraltibial axial alignment,allows for healing of the articular cartilage.Satisfactory results were obtained.

Objective To analyze the causes, prevention and treatment measures for nerve palsy complications in artificial hip replacement. Methods A total of 413 consecutive hip replacements performed from January 1991 to December 2001 were retrospectively studied. There were three cases of nerve palsy with a prevalence of 0.73%. Among them, there were two cases of sciatic nerve palsy and one femoral nerve palsy. Results The causes for nerve palsy in these three cases were hypotension shock due to excessive anticoagulation against deep venous thrombosis, hematoma compression and unknown causes respectively. The neuronal function of three cases of nerve palsy was recovered at different degrees through correction of shock, clearance of hematoma and rehabilitation therapy. Conclusions The causes for nerve palsy complication during artificial hip replacement are direct or indirect traction, compression and ischemia. Understanding the etiology of nerve palsy to avoid the nerve injury, immediate and correct management play an important role in prevention and treatment of nerve palsy during artificial hip replacement.

Objective:To provide reference for the treatment of lipoprotein glomerulopathy and to investigate the participation of clinical pharmacists in the whole treatment course. Methods: Three different treatment regimens, including immunosuppressive thera-py, dual plasma filtration therapy and lipid-lowering combined with reducing urinary protein therapy was respectively adopted for one patient with lipoprotein glomerulopathy, and the efficacy was evaluated. Clinical pharmacists assisted physicians in deciding treatment regimen, performed pharmaceutical care, adjusted medication and analyzed the prognosis of the patient during the follow-up. Results:1. Immunosuppressive therapy was ineffective for the patient;2. The dual filtration acted quickly, while the expense was high and the disease was easy to relapse;3. The third therapy was relatively safer and more economical with long-term effect. Conclusion:Combi-nation therapy of lowering lipid and reducing urinary protein is the most suitable treatment regimen for the patient with lipoprotein glo-merulopathy. Clinical pharmacists play an important role in the whole course of treatment to assist physicians in obtaining the maximum benefit of patients.

Objective To test comparative effect of capecitabine and S-1 (Tegafur/gimeracil/oteracil) on advanced colorectal cancer.Methods 106 cases of advanced colorectal cancer in our hospital oncology were collected and randomly divided into 2 groups:capecitabine group (52 cases) and S-1 group (54 cases).The chemotherapy effect and adverse effect of 2 groups were collected.Results After one treatment period,3 cases of complete remission,19 cases of partial remission,15 cases of stable disease,15 cases of disease progression,efficient rate of 42.3％and control rate of 71.2％ were observed in capecitabine group.5 cases of complete remission,21cases of partial remission,19 cases of stable disease,9 cases of disease progression and efficient rate of 48.1％ and control rate of 83.3％ were observed in S-1 group.There were no significant differences in efficient rate,control rate adverse effect rate and survival time between 2 groups(P ＞ 0.05).Conclusion Capecitabine and S-1 are both safe and effective in treatment of advanced colorectal cancer.

Aim To amplify P30 gene and express P30 fusion with GST Methods P30 gene was smplified from T. gondii chromosomal DNA and ligated to pGEM-T and pGEX-4T-1. Screening-positive recombinants were induced for expression, which was subsequently detected by WB Results P30 gene was amplified and GST-fusion was confirmed by rabbit antiT. gondii serum. Conclusions The construction of pGEM-T-P30 and pGEX-4T-1-P30, together with the recombinant protein would lay a base for further investigation of P30 at a molecule-level and application to diagnosis and vaccination

0.05). However, compound muscle action potential (CMAP) amplitude in ims injected group wa s si gnificantly higher as compared with the other two groups[ims injected group (12.50?2.06) mV, iv group (1.50?0.20) mV, control group (10.13?4.04) mV, F=6.347, P=0.033]. The MSC s were able to be observed only in ims injected tissues 3 weeks after implantati on (A large number of small undifferentiated cells were found outside the myofib ers and some were found between the cells.) The atrophy of gastrocnemius in ims injected group was much less severe than that of the other 2 groups. The diameter of muscle fibers was significantly longer on d60 (F=4.537,P=0.021).Conclusion:Intra- muscular injection of MSC was well distributed in denervated muscle, which provides a newway of nerve regeneration in the rat model of sciatic nerve injury.

Objective: To explore the effect of Laminarina Japonica Polysaccharides (LJPS) on blood glucose in diabetes mice.Methods: Effect of LJPS on alloxan inducing diabetes mellitus model was investigated by applying different doses(125,250 and 500mg/kg bw).Results: The doses of LJPS were able to lower blood glucose level by 34.96%,20.70% and 26.82% respectively. They also decreased BUN level, enhanced liver glycogen, calcium in serum and insulin concentration. LJPS could restore the injury of alloxan induced pancreas islet significantly by histopathological findingConclusion: The results show that LJPS is an active component in protecting against alloxan induced pancreas injury and mediating the blood glucose level.

Objective To study the clinical effect of lienal polypeptide injection combined with chemotherapy on patients with advanced diffuse large B-cell lymphoma. Methods Sixty patients with advanced diffuse large B-cell lymphoma were randomly divided into investigative group (30 cases) and control group (30 cases). Patients in the investigative group were administrated with lienal polypeptide injections when undergoing chemotherapy, while patients in the control group were given only chemotherapy. The clinical effect and immune function in the two groups were compared. Results After chemotherapy, the average Karnofsky score and T cell subpopulations in the investigative group were higher than those in the control group (all P<0.05). At the same time, the rate of chemotherapy related hematologictoxicity in the investigative group was significantly lower than that in the control group (P<0.05). The response rates of investigative group and control group were 80 %(24/30) and 73 %(22/30), respectively, with no statistical significance (P=0.897). Conclusion During chemotherapy, the addition of lienal polypeptide injection will improve the immune function of patients with advanced diffuse large B-cell lymphoma, stimulate bone marrow function and improve the quality of life.
