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 investigate the risk factors for hip fracture in elderly people in Ningbo,in order to provide the basis for prevention and treatment of hip fracture.Methods A case-control study were conducted in study on 450 cases of hip fracture patients aged over 60 years in Ningbo and 450 subjects of control as 1 ∶ 1 matched case control study.A univariate analysis of hip fracture was performed by x2 test.Risk factors for hip fracture were analyzed by logistic regression.Results Poor self-care ability (OR=5.05),light manual labor occupation (OR=4.10),history of cerebrovascular events (OR=2.59),smoking (OR=2.14) were the risk factors for hip fracture in elderly men,while poor self-care ability (OR=11.36),light manual labor occupation (OR=2.41),osteoporosis (OR=3.19),early menopause (OR=6.89),low body mass index (OR=5.05) were the risk factors for hip fracture in elderly women.The protective factors for hip fracture was milk uptake (OR=0.29) Conclusions Early interventions for hip fracture risk factors,and prevention and treatment of osteoporosis can help reduce the occurrence of hip fracture.

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.

AIM: To study the protective effect of hepatic stimulator substance(HSS) on chemotherapeutic liver damage induced by cyclophosphamide and its possible mechanism.METHODS: The serum biochemical parameters,oxidative parameters and anti-oxidative parameters of liver tissue of male Kunming mice inoculated with S_(180) cells were measured.The pathology of the liver was observed with microscope.The weight of S_(180) sarcom was weighted.RESULTS: The elevation of MDA content of liver tissue and the less of GSH content and CAT,GSH-PX,GST,and SOD activities induced by CP were restored remarkably by HSS.The ALT and LDH activities of serum in HSS group which was compared with control group and CP group were not statistically distinctive.In the pathologic examination,spotty and focal necroses of hepatocytes in the liver of CP group were found with a great deal of inflammatory cells infiltration in the necrotic and portal areas,while the damage in the liver of HSS group was ameliorated obviously;The weight of S_(180) sarcom in CP group and HSS group was not statistically distinctive.CONCLUSION: The effect of HSS on CP-induced chemotherapeutic liver damage maybe due to anti-oxidative activity.

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.
