ABSTRACT
Objective To explore the expression difference of cytokines related to nuclear factor kappa B (NF-κB) signaling pathway among different traditional Chinese medicine (TCM) syndromes in the patients with diabetic nephropathy (DN).Methods Serum tumor necrosis factor-α (TNF-α),interleukin-1 (IL-1),interleukin-6 (IL-6) and interleukin-8 (IL-8) in 146 patients with DN and 62 individuals undergoing healthy physical examination in the control group were measured.Results The levels of serum TNF-α,IL-1,IL-6 and IL-8 in various DN groups were significantly higher than those in the control group (P＜0.05).The levels of serum TNF-α,IL-1,IL-6 and IL-8 were significantly different among groups of different TCM syndromes (P＜0.05).With the progression of DN,all cytokines levels showed a gradually increasing trend,moreover the increased extents and time were different in different TCM syndrome types of DN.Conclusion The levels of serum TNF-α,IL-1,IL-6 and IL-8 related to NF-κB signaling pathway are correlated with different TCM syndromes types and may play a role in the occurrence and progression of different TCM syndrome types of DN.
ABSTRACT
Objective To compare and evaluate the performance and applications of three assays in preliminary screening of dengue infections.Methods This study was designed as a retrospective study.Clinical data were obtained from 2 137 borderline cases from September to October in 2014 and 2015.Markers of dengue infections of serum samples were detected by NS1 antigen captured ELISA, dengue NS1 detect rapid test and dengue IgM detect rapid test, respectively.Chi square test was used to compare the preliminary screening value of these 3 methods.Forty-eight diagnosed patients were also examined in the 1st-3rd day, 4th-5th day, 6th-7th days and 14th day after infection to access the sensitivities and specificities of three assays.Results Nine hundred and fifty-seven ( 57.2%) cases in 2014 and 48 ( 10.4%) cases in 2015 were diagnosed to be Dengue fever of 2 137 borderline cases.The overall sensitivity of NS1-ELISA was superior to NS1 and IgM rapid detect test (χ2 =40.865,P<0.001;χ2 =151.383,P<0.001).No significant differences were found in specificity between three assays(χ2 =0.661,P=0.416;χ2 =0.548,P=0.459; χ2 =2.397,P=0.122).The NS1 detecting assays were sensitive in 7 days after infection, but the sensitivity of IgM detecting assay increased over time.Conclusions NS1 detecting assays had good sensitivities and specificities, which can be used as an important method in preliminary screening of dengue infection.ELISA or rapid test can be selected according to epidemic situation.
ABSTRACT
Objective To explore the effect of the combination of benazepril and beraprost sodium on urinary microalbumin (UMA), serum high sensitivity C-reactive protein (hs-CRP) and TNF-α in patients with diabetic nephropathy(DN) in early stage. Methods From Mar. 2010 to Mar. 2013, 120 patients with early-stage DN were randomly divided into Benazepril Group, Beraprost Sodium Group and Combination Group. Each group consisted of 40 patients with medical therapy in 20-week duration. The levels of 24 h-UMA, serum hs-CRP and TNF-α were detected and compared before and after therapy. Results After treatment, the levels of 24 h-UMA, serum hs-CRP and TNF-αall decreased significantly in three groups (P<0.05) and there were lower 24 h-UMA, serum hs-CRP and TNF-αin Combination Group than those in Benazepril Group and Berapros sodium Group (P <0.05). Conclusion There is coordinating protection of combination of benazepril and beraprost sodium on diabetic nephropathy in early stage, possibly being related with the inhibiting of micro-inflammation.
ABSTRACT
Objective To investigate the early intervention to improve calcium and phosphorus metabolism in chronic kidney disease patients left ventricular hypertrophy. Methods 116 cases of non-dialysis patients with chronic kidney disease were randomly divided into 3,4-intervention group and control group, intervention group patients with calcium and phosphorus metabolism in early intervention were observed in patients with calcium, phosphorus, and left ventricular mass index changes. Results Patients in the intervention group after the intervention of phosphorus,calcium and phosphorus product,serum parathyroid hormone were significantly lower than the control group,the difference was all statistically significant (all P＜0.05 );intervention group of LVMI was significantly lower than before the intervention, but also significantly lower than the control group, the difference was statistically significant (P＜0.05). Conclusion Patients with chronic renal calcium and phosphorus metabolism of early intervention can improve symptoms in patients with left ventricular hypertrophy is beneficial to the improvement of patients with the disease.
