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.

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 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.

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.

0.05).At the same time,loss of ranges of neck motion was 4.6??4.0?in group A and 11.6??7.8?in group B,significant difference was also seen(P

[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.
