Several signaling pathways are involved in clonal proliferation of lymphoma cells and disease progression. It has been shown that cyclic adenosine monophosphate (cAMP) signaling pathway, as an important intra-cellular messenger delivery system, is related to modulation of multiple physiological processes including cell prolifer-ation, secretion, metabolism and apoptosis. Manipulating the cAMP signaling pathway can induce cell cycle arrest and apoptosis of various malignant lymphoid cells, which involves mitochondria-dependent apoptosis and cAMP-modulated protein kinases as well as changes of intracellular mediators. In-depth research and analysis of cAMP-induced apoptosis in lymphoma cells would provide potential targets and possible therapeutic means for the treatment of lymphoma.

[Objective]To treat the femoral neck fracture using cannulated screw and BMP release system in animals,and to evaluate the possibility of treating femoral neck fracture and provide experimental basis for clinical application.[Method]Eighteen mongeral were used in this study.The model of bilateral femoral neck dislocation fracture was established.The control side was fixed using cannulated screw,and the experiment side was fixed with cannulated screw and injectable BMP release system.At 4,8,12 weeks,6 animals were sacrificed at one time point respectively.Results were obtained through histology,radiography,scintimetry and gross observation.[Result]The fracture line was vague at four weeks,and at eight weeks the fracture line almost disappeared.It was healed completely at twelve weeks.Radiological study showed that the healing of the fracture in experimental side was better than that of the control side.There was the same result of observation in histology.[Conclusion]The cannulated screw combined with BMP used in the experiment is effective and feasible.It may not only provide strong internal fixation but also infuse growth factor into site of fracture.It would accelerate the reconstructing of the vascular supply to the femoral head after the fracture and promote the restoration of bone.

Objective To measure the extent of malrotation of femur fractures with CT scan after fixation with interlocking intramedullary nailing , and to discuss the methods which can help to correct the malrotation of femur fracture during the operation. MethodWith CT scan, the anteversion of femur fracture after the close reduction and fixation with interlocking intramedullary nailing in 56 cases was measured, and the difference of anteversion between the fracture side and the contralateral side was evaluated. The increase of anteversion represented internal rotation of the distal fragment, whereas the decrease of anteversion meaned external rotation. According to AO classification system, the type A of infratrochanteric fractures happened in 9 cases, type A of femoral shaft fractures happened in 12 cases, type B in 15 cases,type C in 7 cases,and 13 cases of femoral supercondyle fractures were type A. ResultThe results of measurement showed that the femoral anteversion after fixation with interlocking intramedullary nailing was changed in all patients. The anteversion of the femoral shaft fracture ranged from 13.35?to 47.21?. The aneversion of infrotrochanteric fractures ranged from -7.12?to 36.35?, and the supercondyle fracture of femur from -11.10?to 39.22?. For the extent of malrotation of distal femoral fracture, the internal rotation was more obvious than the external rotation. The number of Internal rotation cases accounted for 60.71%, and the external cases accounted for 39.29%. The maximum internal malrotation happened in femoral shaft fracture, from 1.37?to 29.82?with average malrotation 12.34?. and the minimum internal malrotation happened in infratrochanteri fracture, from 0.81?to 23.21?,with the average malrotation 8.32?. The medium internal malrotation was femoral supercondyle fracture, from 1.72?to 27.11? with the average malrotation 8.38?. The maximum external malrotation happened in femoral shaft fracture, from 1.11?to 21.12?with the average of them 9.33?. The minimum external malrotation happened in infratrochanteri fracture, from 1.31?to 16.23?with the average 7.71?. The medium external malrotation was seen in femoral supercondyle fracture, from 0.97?to 17.96?with average 8.22?. For these three parts of femoral fracture, the partnership T test was done between the fracture side and the contralateral side, the results showed that there were significant differences among of them,P

Objective To compare 2 methods to immobilize probes on the surface of gold membrane and select the better one for aptamer immobilization of aptamer-based piezoelectric quartz crystal sensor. Methods Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal sensor with thiol method or biotin-avidin method. The changes of frequency were compared in reactions with different concentrations of IgE. Results Biotin-avidin method obtained higher frequency changes in the reactions of IgE, lower limit of detection and wider liner range than thiol method. For biotin-avidin method, there was significant linear correlation between frequency changes and the concentration of IgE with the correlation coefficient of 0.994 5. Conclusion The thiol method which is proved effective for probe immobilization on gene sensor is unfit for aptamer immobilization. Biotin-avidin method has a better ability to immobilize probe on the surfaces of aptamer-based piezoelectric quartz crystal sensor.

Objective: To explore and discuss the clinical curative effect on intermittent positive pressure breathing therapy of non - invasive ventilator in the treatment for chronic obstructive pulmonary disease (COPD) of elderly patients with complication of acute respiratory failure. Methods: 112 elderly patients who were COPD (all of patients were acute exacerbation period) with complication of acute respiratory failure were divided into control group (60 cases) and observation group (52 cases) as the random number table. A series of basic therapy including routine anti-inflammatory, relieving asthma and expectorant therapy were implemented for all of patient. And the non-invasive ventilator was used to implement non-invasive mechanical breathing therapy. In this therapy, patients of control group were implemented sustaining positive pressure breathing therapy, while patients of observation group were implement intermittent non-invasive positive pressure breathing therapy (1:1). The curative effect, pH value (at 6,24 and 72h), PaO2 (at 6,24 and 72h), PaCO2 (at 6,24 and 72h) and complications between the two methods were compared. Results: There was no significant difference in the general demographic characteristics between the two groups. For patients at 6, 24 and 72 h, the differences of the pH value, PaO2and PaCO2 between pre and post-treatment were significant in observation group (F=5.669, F=6.985, F=7.628, P<0.05) and control group (F=5.311, F=6.892, F=7.958, P<0.05) , respectively. The differences of the pH value, PaO2 and PaCO2 at 6h, 24h and 72h were significant (at 24h, F=6.776, F=7.098, F=7.673. at 72 h, F=7.883, F=6.983, F=7.335, P<0.05),respectively. For two groups, the differences of pH value, PaO2 and PaCO2 at pre-weaning, post-weaning 6h and post-weaning 12h were not significant. While the mechanical ventilation time and mechanical ventilation rate of observation group were significant lower than that of control group (t=3.591, x2=3.052, P<0.05). Besides, the incidences of complications including flatulence, trachea intubation, respiratory and relative pneumonia of observation group were significant lower than that of control group (x2=4.997, P<0.05). Conclusion: The new method can significantly shorten duration of breathing and duration of hospital stays. And its incidence of complication is lower while safety of treatment is relatively higher than that of traditional method.
