Objective To investigate the characteristics of glucose and lipid metabolism in the male primary aldosteronism(PA) patients .Methods 125 male PA patients screened out by using plasma aldosterone/renin ratio(ARR) plasma aldosterone concen‐tration measurement were enrolled in the study(PA group) ,at the same time 127 male patients with essential hypertension(EH) were also recruited as EH group ,who had similar blood pressure levels and hypertension course .Clinical data and biochemical indi‐cators of each group were collected and the characteristics of glucose and lipid metabolism in the male PA patients were analyzed . Results Serum potassium level of PA group was lower than EH group(P<0 .05) .Compared with EH group ,there were significant increase of triglycerides concentration in PA group(P<0 .05) ,and significant decrease of HDL‐C concentration in PA group(P<0 .05) .Oral glucose tolerance test(OGTT) 2 h glucose level and waist in PA group were higher or larger than that in EH group (P<0 .05) .Conclusion Compared with EH patients ,glucose and lipid metabolism disorder are more severe in male PA patients , the symptoms are mainly abdominal obesity and impaired glucose tolerance .

OBJECTIVE: To synthesize a kind of novel cytotoxin with multi-drug-resistance reverting properties and study their cytotoxicity. METHODS: The target compounds were obtained from N-benzyl-4-piperidones and benzaldehyde derivatives on the condition of 20°C, 7-8 h, taking dry hydrogen chloride as catalyst, using aldol condensation reaction, inspected by TLC and purified through recrystallization. RESULTS: Five N-benzyl-3, 5-bis(arylmethylene)-4-piperidone derivatives were synthesized. The yield was over 49%. Their structures were characterized by 1H-NMR, ESI-MS with melting points. The data of cytotoxicity was obtained. CONCLUSION: The synthetic route is convenient and efficient; The compounds had good inhibiting activity for a few kinds of tumor cells.

SiRNA comes from double-stranded RNA,which is processed into a small molecular fragment by Dicer.21-25nt siRNA,as the key effector molecules to the RNAi process,can inhibit gene expression with high specificity and high efficiency in mammalian cells.Currently,RNAi has been widely applied in a variety of cancer.RNAi has many active research explorations of the tumor development,metastasis and treatment in gastrointestinal cancer.

To investigate the relationship between the diameter of abdominal aortic aneurysm(AAA) and the concentration of elastin, forty five healthy male Wistar rats were selected,5 rats of them were used as normal control, the other 40 rats were randomly divided into 2 groups. A 1 cm segment of the abdominal aorta of the rat was isolated and perfused with pancreatic elastase in the experimental group, and the control group was given normal saline solution. Laparotomy was performed immediately after operation and on the 2, 7, 14 day, the aortas were measured and harvested. Histological studies were carried out to analyze the changes in elastin. The aortic diameter progressed to aneurysmal dimension in the experimental group. Histological study revealed loss of elastin in tunica media of the aorta in the experimental group. Neither macroscopic nor microscopic lesions were found in control group. It is suggested that there is a significant correlation between the aortic diameter and the decreased elastin content.

Objective To investigate the clinical value of 99mTc-MDP SPECT/CT whole body bone imaging in the diagnosis of bone metastasis of prostate cancer. Methods A total of 107 cases with prostate cancer were di-agnosed by SPECT whole body bone imaging from January 2013 to November 2016. SPECT/CT imaging of some ab-normal density collective focus found in whole body bone imaging were further carried out. Six months later ,whole body bone imaging and SPECT/CT were made again for review. In all diagnosis above ,99mTc-MDP were selected as bone imaging agent. According to the results of follow-up visit clinical and imaging diagnosis ,diagnostic perfor-mance indicators of whole body bone imaging and SPECT/CT were calculated. Results The different part of whole body bone imaging and SPECT/CT in the diagnosis of bone metastases was statistically significant(x2 = 23.000, P < 0.001). The diagnosis specificity and coincidence rate of SPECT/CT for bone metastasis were 100.0% and 98.1% respectively and they were significantly higher than those of whole body bone imaging(65.0% and 80.4%respectively). The differences were statistically significant(P < 0.05). After SPECT/CT diagnosis,a total of 193 undetermined lesions were found and 83 lesions of these were final diagnosed of bone metastases. Pelvic lesions were most in bone metastases ,accounting for 50.6%. Conclusion Whole body bone imaging can effectively determine the undetermined lesions , further SPECT/CT can significantly improve the diagnostic accuracy of prostate cancer bone metastasis.

Objective To investigate the number and activity changes of endothelial progenitor cells(EPCs) in hemodialysis patients,and explore its correlation with the risk factors of coronary heart disease.Methords Total mononuclear ceils(MNCs) were isolated from peripheral blood of patients with chronic renal failure in long-term hemodialysis and from a normal control group by Ficoll density gradient centrifugation and then were plated on humanfibronectin-coated dishes.Mter 7 days of culture,EPCs were characterized as adherent cells by double staining with FITC-UEA-I and DI-LDL,and were further identified by the expression of CD34,CD133 and KDR with flow cytometry.EPCs migration was determined with modified Boyden chamber assay.EPCs adhesive assay was performed by replanting EPCs on humanfibronectin-coated plates and then counting the adherent cells.The relationship of the EPCs' number and activity with Framingham Risk Score of ten years was also be assessed.Results Number of EPCs and the migratory & adhesive capacity were significantly lower in patients than in the control(P
