Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid （UA） metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical charac- teristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure （n = 553）. By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid （SUA） formed part of a principal cluster of renal functional variables which included serum creatinine （SCr） and blood urea nitrogen （BUN）. Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN （r = 0.48, P 〈 0.001） and SCr （r = 0.47, P 〈 0.001）. Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.展开更多

Methods The medical reports of 47 MS patients admitted to Peking Union Medical College Hospi- tal during 2008 and 2010 were reviewed. And 49 age- and gender-matched cerebral infarction patients were enrolled as control. The mean serum HA level of the MS patients was compared with that of the control group. The correlations between the HA levels and the clinical parameters including gender, disease duration, relapse rate, and disease disabilities as assessed by the Expanded Disability Status Scale score, were explored. Forty-one patients had CSF examinations. The correlations between the IdA levels and the CSF parameters reflecting inflammation and tissue damage, including CSF protein, white blood cell count, oligoclonal band, 24-hour IgG index, and myelin basic protein, were also investigated. Results The mean serum HA level in the MS patients was lower than that in the control group （247.75 ± 52.59 jamol/L vs. 277.94 ± 74.33 pmol/L, P=0.025） and inversely correlated with the relapse rate （P=0.049）. MS patients with lower serum UA levels tended to have higher white blood cell counts and myelin basic protein level. But there was no correlation between CSF protein levels （r=0.165, P=0.273）, white blood cell counts （r=-0.051, P=0.732）, IgG index （r =0. 045, P=0.802）, or myelin basic protein level （r =-0.248, P=0.145） and the serum UA level, respectively. Conclusion In MS patients, UA levels might partly reflect the extent of disability and inflammation.展开更多

METHODS： Ninety individuals were enrolled in the study： 30 in each study group： patients with postprandial distress syndrome （PDS）, epigastric pain syndrome （EPS）, and controls. Blood samples were drawn at 02：00 and 09：00 h and 24-h urine collection was performed. Serum melatonin and urinary 6-OHMS concentrations were measured by enzyme-linked immunosorbent assay. RESULTS： Serum melatonin concentration at night and in the morning was significantly （P 〈 0.001） higher inPDS patients [at 02：00 h-93.3 pg/mL, quartile range （QR）： 79.8-116.2; at 09.00 h-14.3 pg/mL, QR： 7.06-19.0] than in EPS （57.2 pg/mL, QR： 42.6-73.1, 8.1 pg/mL, QR： 4.2-9.3） and control patients （57.7 pg/mL, QR： 51.2-62.5; 8.1 pg/mL, QR： 5.4-10.3）. A similar relationship was observed for urinary 6-OHMS excretion. Patients with severe PDS symptoms had a higher melatonin concentration than these with moderate syndromes, whereas patients with severe EPS had a lower urinary 6-OHMS excretion than patients with moderate symptoms.CONCLUSION： Evaluation of melatonin serum concentrations and 24-h urinary 6-OHMS excretion are useful methods for differential diagnosis of various clinical forms of FD.展开更多

Methods： Type 2 diabetes mellitus（T2DM） subjects with incipient diabetic nephropathy with or without macrovascular disease were selected for participation and divided into 2 groups. The patients in group 1 （n= 38） used insulin, and patients in group 2 （n=34） were treated with an oral antidiabetic drug. Then serum mmp-9, hey, IL-6 and TNF-α in these patients were measured, and compared to the healthy subjects as control （n= 16）. The results were analyzed by SPSS13. Results： Serum romp-9 and hcy of the patients having incipient diabetic nephropathy with macrovascular disease were higher than that of patients without macrovascular disease （P〈0.01）. For insulin-injected patients, whether they accompanied with macrovascular diseases or not, the serum levels of romp-9, hcy, IL-6 and TNF-α were all lower, but no significant statistics compared with non-insulin used patients or the healthy subjects. The serum level of romp-9 was more correlated with the serum hcy in antidiabetic drug used patients. （P〈0. 000） Conclusion： The serum level of romp-9 plays an important role of pathogenesis in the macrovascular disease in the incipient diabetic patients, and the serum level of hcy also can reflect the severely degree of macrovascular disease in these patients, insulin can reduce these markers.展开更多
