BACKGROUND:It wil provide a new insight into the future application of bone marrow mesenchymal stem cels in the treatment of spinal cord injury and tissue engineering by studying the effect of activation of Wnt signaling pathway in the neuronal differentiation of bone marrow mesenchymal stem cels.
OBJECTIVE: To detect the expression of related genes by gene chip technology during the neuronal differentiation of bone marrow mesenchymal stem cels.
METHODS:Human bone marrow mesenchymal stem cels were isolated and purified, and passage 5 cels were obtained. GatewayTM technology was used to build lentiviral vectors that was used to transfect Wnt-1 into human bone marrow mesenchymal stem cels. Control, non-transduction and transduction groups were set in this study. Human bone marrow mesenchymal stem cels were then induced to differentiate into neurons. Cel morphology was observed under inverted phase contrast microscope. Gene chip was used to detect the regulation changes and the differential expression of related genes in the Wnt signaling pathway.
RESULTS AND CONCLUSION: Under the scanning electron microscope, the transfected cels were found to have the similar morphology of neuron-like cels. Analysis by the gene chip hybridization technique showed that 3 287 genes were up-regulated and 4 215 genes were down-regulated in the signal pathway. In the Wnt signaling pathway, genes related to the nervous system development and differentiation were up- or down-regulated. It is verified that the Wnt signal pathway is activated via Wnt-1 transduction, and the downstream genes appear to have genetic transcription so as to promote the neuronal differentiation of human bone marrow mesenchymal stem cels.

Six patients were treated with radiotherapy alone or combined with chemotherapy, 9, with surgery and postoperative radiotherapy and 1,with operative alone. The radiation dosage ranged from 40～70Gy with 2 Gy per day. Results:The 1 , 3 and 5 year survival rates were 75%, 75% and 69%.Conclusions:Olfactory neuroblastoma is sensitivity for radiotherapy, for the patients with stage A, radiotherapy alone is effective for stage B and C olfactory neuroblastoma , combined modality of surgery and postoperative radiotherapy should be the treatment of choice.

Objective To investigate the therapeutic effect of non-invasive positi e pressure ventilation (NIPPV) in the treatment of patients with acute exacerbations of chronic obstructive pulmonary disease(AECOPD).Methods 68 AECOPD patients with type Ⅱ repiratory failure were randomly divided into control group and treatment group.The control group was treated by conventional therapy alone and the treatment group was given conventional therapy combined with NIPPV.The levels of power of hydrogen (pH),partial pressure of carbon dioxide in artery(PaCO2),arterial oxygen tension(PaO2),heart rate and repiratory rate were compared between the two groups.The mean length of patient stay,the frequency of tracheal intubation and the hospital mortality were analyzed after discharge from the hospital.Results Before treatment,the arterial blood gas analysis showed that the pH,PaCO2 and PaO2 had no significant differences between the two groups(all P ＞ 0.05).After treatment,compared with the control group,the levels of pH,PaCO2 and PaO2 were obviously improved(all P ＜0.05).The mean length of patients stay in the treatment group was significantly shorter than the control group(P ＜ 0.05).The frequency of tracheal intubation of the treatment group was significantly lower than the control group(P ＜ 0.05).The hospital mortality was lower in the treatment group,but the difference between the two groups was not significant (P ＞ 0.05).Conclusion NIPPV for treating the AECOPD can improve the arterial blood gas analysis,decrease the need of tracheal intubation and shorten hospitalization time.

ObjectiveTo study the risk factors and pathogenic characteristics of ventilator associated pneumonia(YAP). MethodsRisk factors of VAP,pathogens and drug resistance in 118 patients in ICU were analyzed retrospectively. ResultsThe incidence of VAP was 44.9％, and age, the mechanical ventilation time, state of consciousness,tracheotomy,the antibiotic combination are risk factors of incidence of VAP. 53cases of VAP(68.2％ )were infected by Gram negative bacilli,25.9％ were by Gram positive cocci,and 5.9％ were by fungi. Drug resistance was observed obviously. ConclusionThe occurrence of VAP was related with multiple factors. The gram negative bacteria are the major pathogens of VAP, and the rate of drug resistance was high. The occurrence of VAP could severely affect patients' prognosis.

Objective To understand the status of Clonorchis sinensis infection and its risk factors in Futian District Shen?zhen City so as to provide the evidence for formulating the strategy of prevention and control. Methods Two monitoring points were randomly selected and the permanent population aged≥3 years were investigated and their stool samples were detected for the eggs of C. sinensis by using Kato?Katz technique. Meanwhile the risk factors of infection were also investigated. Results A total of 743 subjects were examined and 7 persons were infected with C. sinensis and the infection rate was 0.94%. Most of the infected cases were focused on 20?40 and 40?60 age groups. The risk factors were eating raw or semi?cooked fish and the protec?tive factor was the use of separated cutting board for cooked or uncooked food. Conclusion The infection rate of C. sinensis is low in the population of Futian District. However the health education especially for diet health education still should be strengthened.
