BACKGROUND:As a traditional treatment for multilevel cervical myelopathy,nterior long-segmental decompression has the shortcomings of great operative trauma,high difficulty,low fusion rate,etc.,which can affect the postoperative efficacy.OBJ ECTIVE:To evaluate the clinical effects of three different anterior surgeries on multilevel cervical myelopathy.DESIGN:A comparative observation.SETTING:Department of Orthopaedics,Changzheog Hospital,the Second Military Medical University of Chinese PLA.PARTICIPANTS:Thirty-six patients with multilevel cervical myelopathy of 3 consecutive segments,who were surgically treated,were selected from the Department of Orthopaedics,Changzheng Hospital,the Second Military Medical University of Chinese PLA from June 1999 to June 2003,including 25 males and 11 females,35-62 years of age,the disease course ranged from 3 to 26 months. According to the clinical manifestations and imaging esults,they were diagnosed as multilevel cervical myelopathy,and they were not suffering from consecutive ossification of posterior longitudinal ligament and ossification of ligamenta flava. Informed contents were obtained from all the patients and their relatives.METHODS:All the patients were grafted with utologous bone. Autologous ilium or cancellous bone excluding vertebral body was filled into titan net or Cage,which were made of titan and characterized by high intensity,tolerance to decay,good biocompatibility,etc. According to the operative manner,the patients were divided into 3 groups:① two-level corpectomy with fusion group(long-segmental decompression group,n =11):There were 4 cases grafted with long-titan net,and 7 cases grafted with autologous iliac bone. Sub-total two-level corpectomy with fusion was performed. ②segmental decompression group(n =16):including 12 cases of titan net+cage graft,4 cases of autologous bone+cage graft. One-level decompression and sub-total single corpectomy with fusion were performed. ③three-level decompression group(n =9):Only discectomy without corpectomy was performed. After complete decompression,3cages were used to fill artificial bone or grafted with autologous bone.MAIN OUTCOME MEASURES:Cervical anteroposterior and lateral radiographies,flexion and extension radiograph were reexamined within 1 week and at 3,6 and 12 months postoperatively. The neurological function was assessed using the Japanese Orthopaedic Association(JOA) scoring method preoperatively and 3 months postoperatively. The total score was 17 points,the higher the score,the better the neurological function. The duration of operation,perioperative bleeding amount,length of stay,cost of hospitalization,graft fusion at 3 months postoperatively,improved JOA score at 3 months postoperatively were recorded in the three groups. The occurrence of postoperative complications was observed by means of return visit.RESULTS:All the 36 patients with multilevel cervical myelopathy were involved in the analysis of results. The mean duration of operation,mean perioperative bleeding amount and mean length of stay in the segmental-decompression group and three-level decompression group were obviously fewer or shorter than those in the long-segmental decompression group(P < 0.05),and the average cost of hospitalization was obviously higher than that in the long-segmental decompression group(P < 0.05). The postoperative improved JOA score and graft fusion rate were close among the groups(P > 0.05).CONCLUSION:Segmental anterior cervical decompression is a recommendable technique for multilevel cervical myelopathy by comprehensively considering the fusion rate,recovery of neurological function,duration of operation,perioperative bleeding and length of stay.

AIM:To explore the feasibility and biological characterization of long-term regulated expansion of JAK2 transduced human CD34+ cord blood cells in vitro.METHODS: A retrovirus (RV) vector which contains JAK2 catalytic domain and two binding sites for a chemical inducer, dimerization (AP20187), was cloned (designated MGI-F2JAK2). CD34+cells were enriched from cord blood with a MiniMACS system. The purified CD34+cells were transfected with supernatant from the retrovirus packaging cell line that expressed JAK2. Following transduction, cells were expanded into four groups: AP20187 alone, FL alone, TPO, alone, AP20187+FL+TPO, respectively. The expanded cells were monitored by GFP expression, immunophenotyping, progenitor colony assay, karyotype analysis as well as tumorigenesis in nude mice. RESULTS: The purity of selected CD34+ cells was over 91% and gene transfer rate was 49.32%?6.21%. Only the group of AP20187 +FL+ TPO was obtained a significant sustained outgrowth of the transduced CD34+ cord blood cells. The percentage of GFP+ cells consistently produced a rise to the 90% peak level by the end of 8th week of culture. Flow cytometry analysis showed that the phenotype of the expanded cells was CD33+, CD61+ and Gly-A+ partial positive; CD38+ and HLA-DR+ strong positive, while CD2, CD7 and CD19 were almost negative. Colony assays performed in methycelluos, which can give rise to BFU-E, CFU-GM and CFU-Mix, the CFU-GM was predominantly in all colonies. The tumor was not observed in nude mice and the karyotype analysis was normal from expanded cells.CONCLUSION: The results demonstrate that AP20187-mediated activation of JAK2 signaling is capable of stimulating expansion JAK2 transduced CB CD34+ cells in combination with FL and TPO. This system may have applications for studies in signaling transduction, hematopoiesis, and for gene and cell therapy.

Objective To study the effect of social isolation( SI) on the exploratory behavior and working memory in mice. Methods The Kunming mice of postnatal 21 days were divided into the control group,SI 2 weeks group,SI 2 weeks gregarious group,SI 4 weeks group and SI 8 weeks group,according to randomized design with ten animals each. All isolated mice were isolated for 2, 4 and 8 weeks respectively, the gregarious group were housed under normal grouped housing enviroment after isolation until adult, the mice with the relative same age were control groups. All animals were measured for exploratory behavior and working memory by performing open field and T?maze after the treatment. Results In the open field,compared to the relative control group,the central area of the total time in the SI 4 weeks group(0.07±0.04) was less than the control (0.10±0.04) obviously. The central area percentage of total time in SI 8 weeks group (0.64±0.12) were more than the control (0.43±0.08). In the T?maze,the alteration times in SI 2 weeks group (first day (5.92±0.79),second day (6.67±1.3),third day (7.42±1.08),fourth day (8.17±1.27)) were less than the control (first day (6.80±1.14); second day (7.60± 0.84);third day (8.30±0.95);forth day (9.20±1.32)). However,the alteration times of gregarious group showed no obvious change. Both the alteration times of SI 4 weeks (8.18±1.99) in the second day and that of SI 8 weeks (8.29±3.04) in the forth day were more than the control (6.60±2.11) and (7.80±2.53) respectively.Conclu?sions Working memory of SI 2 weeks rats decrease,which can be improved by the resocialization.SI 4 weeks and 8 weeks rats show the decreasing exploring ability and increasing anxiety and work memory.

Objective To explore the clinical and biological characteristics and treatment effect of acute myeloid leukemia (AML) in elderly patients. Methods The clinical data of 62 patients over 60 years old with AML were retrospectively analyzed, and they were compared with those of 60 younger adult patients (18-59 years old) at the same period. Results In elderly patients, the complete remission (CR) rate was 27. 7% and the overall effective rate was 44.7%, which were lower than those of younger adult patients (74.1% and 87.9 %, 1-espectively, P<0.01). The early death rate was 19.0% and the mortality rate during the first two induction chemotherapy was 29. 3% in the elderly, which were higher than those of younger adult patients (3. 3% and 6.7%, 1-espectively,P<0.01). The 27.4% of elderly patients were diagnosed as myelodysplastic syndrome (MDS)-transformed AML, which were more than that of younger adult patients (10.0%, P<0.05), and they had lower CR rate than those without MDS (P<0. 05). The 28.2% of elderly patients had lymphoid antigen positive AML and 71.8% of patients showed CD34+ which were higher than those of younger adult patients (8. 1% and 48.6%, respectively, P<0. 05), and they had lower CR rate than those of lymphoid antigen negative and those of CD34- AML (P<0. 05). Elderly patients had less favorable and more unfavorable karyotypes than younger adult patients (45.7 % and 15.4 %, P<0. 05). Conclusions The elderly patients with AML have more unfavorable prognostic factors than younger adult patients. They have lower CR rate and higher mortality rate. There are many specialties in elderly patients and the treatment strategy should be made more individually.
