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 investigate the effect of valsartan combined with amlodipine in treatment of elderly patients with essential hypertension and diabetes,and to provide a reference for the development of clinical treatment. Methods 339 patients with essential hypertension complicated with diabetes in our hospital were randomly divided into 3 groups:A group,B group and C group,each group in 113 cases.A group was treated with amlodipine tablets,B group was treated with valsartan capsules,and C group was treated with amlodipine tablets combined with valsartan capsules.After 3 months of continuous treatment,blood pressure,blood glucose,blood lipids and uric acid were com-pared among the three groups before and after treatment.Results The three groups of patients before treatment, systolic blood pressure and diastolic blood pressure had no significant difference;The three groups of patients after treatment,systolic blood pressure and diastolic blood pressure were significantly lower than before treatment;After treatment in C group,the systolic blood pressure was (135.70 ±8.17)mmHg,which was significantly lower than (139.42 ±8.29)mmHg in A group and (139.52 ±7.48)mmHg in B group,the difference was statistically significant (t =3.77,3.81,all P <0.05);The three groups of patients after treatment of diastolic blood pressure had no significant difference,and there were no statistical significance among the three groups before treatment in the fasting blood glucose,fasting insulin,ISI level difference;Of A group after treatment,the fasting blood glucose,fasting insulin,ISI levels were (7.63 ±0.89)mmol/L,(16.11 ±2.39)mIU,(-4.26 ±0.35),there were no significant difference before and after treatment;Of B group and C group after treatment,fasting blood glucose,fasting insulin and ISI were significantly lower than before treatment (t =4.45,4.83,6.74,6.61,4.48,4.93,all P <0.05)and A group after treatment(t =4.23,448,5.24,515,409,3.95,all P <0.05),and the differences were statistically significant,and before and after treatment the total cholesterol,triglyceride,high density lipoprotein cholesterol and low density lipo-protein cholesterol levels among the three groups had no statistical significance;the level of uric acid of C group after treatment(282.04 ±81.31)μmol/L was significantly lower than that in A group and B group(t =4.94,4.68,all P <0.05).Conclusion Valsartan combined with amlodipine can effectively reduce the community elderly patients with primary hypertension in patients with diabetes mellitus blood pressure levels,promote the stability of blood glucose level,improve the uric acid metabolism and on renal function have protective effect.

Aim To investigate the effects of Vam3 on ATP-induced inflammatory response in macrophages and the underlying mechanisms. Methods LPS primed mouse peritoneal macrophages were stimulated with ATP,and IL-1βlevel in supernatants was meas-ured by ELISA.Activity of caspase 1 was measured u-sing caspase 1 activity assay kit.Reactive oxygen spe-cies (ROS )level was detected with fluorescent probe DCFH-DA.MTT assay was used to detect cell prolifer-ation,and intracellular Ca2+concentration was meas-ured using laser scanning confocal microscope.Results Extracellular ATP led to increase in IL-1βrelease, caspase 1 activity and ROS production.It also led to rapid increase in intracellular Ca2+concentration and induced cell death.These effects were inhibited by Vam3 .Conclusion Vam3 inhibits ATP-induced in-flammatory response in macrophages,which may sug-gest the blocking effect of Vam3 on caspase 1 ~IL-1βinflammatory signaling pathway in macrophages.

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 compose carbonated hydroxyapatite cement with chemica l materials,and by adding the pore agent to develop a new bone substitute,which can be solidified in situ to form porous carbonated hydroxyapatite.[Method](1)A new type of carbonated hydroxyapatite cement(CHC)was prepared.The powder of cement was composed of calcium carbonate,tricalcium phosphate and calcium phosphate dibasic.The liquids were prepared by 0.2mol/L sodium phosphate buffer,solide phase to liquid phase was 1g to 0.4 ml;(2)To prepare an in situ setting porous carbonated hydroxyapatite cement,add the pore agent into the powder of cement,pore generate CO2 during situ setting of cement;(3)The chemcial composition,chemcial constitution mechanical property,setting time,interval porosity of the PCHA were tested.and then the physio-chemical character,manipulatity,histocompatibility were evaluated.[Result]Addition of pore agent could succeed to prepare a new bone substitute which could set in situ and transform into porous carbonated hydroxyapatite.The setting time was 13~15 minutes which was suitable to clinical application.The pore size and porosity character could be controlled by adjustment of the component.The checking results demonstrated that the self-setting composition of this cement was carbonated hydroxyapatite which was similar with the mineral phase of natural cancellous bone,the carbonic acid radical was 5.6% in the solidify production.Contain of the porosity was 36% with interconnect pore,the compressive strength was 5.6?2.2 MPa which was equal to strength of cancellous bone,and the cytotoxicity tests showed an exellent biocompatibility.[Conclusion]The porous carbonated hydroxyapatite cement is a good bone substitute which seems to be the cancellous bone with good porosities,exellent biocompatibility.
