The aim of ...Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.展开更多

Both IL 6 and TNF α were detected by using ELISA in 22 patients with OSAS and 16 normal controls. The levels of LPS induced IL 6 (787.82±151.97 pg/ml) and TNF α (4165.45±1501.43 pg/ml) expression in the supernatant of the culture of PBMC and plasma level of IL 6 (50.67±4.70 pg/ml) and TNF α (299.09±43.57 pg/ml) in the patients with OSAS were significantly higher than those in the normal controls (in the supernatant of the culture of PBMC: 562.69±197.54 pg/ml and 1596.25±403.08 pg/ml respectively; in the plasma: 12.69±2.75 pg/ml and 101.88±21.27 pg/ml respectively). There were significantly positive correlation between the levels of IL 6 and TNF α and the percentage of time of apnea and hyponea, as well as the percentage of time spending at SaO 2 below 90 % in the total sleep time. It was concluded that LPS induced IL 6 and TNF α levels as well as plasma IL 6 and TNF α levels in the patients with OSAS were up regulated, which may be associated with the pathogenesis of OSAS.展开更多

METHODS: Twenty-eight patients fulfilling the Rome Ⅲ criteria for IBS-D and 28 healthy subjects were in-vestigated. All study participants underwent screening colonoscopy and mucosal biopsies were obtained from the colon and/or terminal ileum. Genomic DNA was ex-tracted from specimens based on standard protocols. Mitochondrial ATP (MT-ATP) 6 and 8 genes in speci-mens were polymerase chain reaction amplified and sequenced. Sequencing data were analyzed via Variant Reporter Software and compared with the reference sequence from Genbank (accession No. NC_012920) to indicate possible polymorphisms. The protocol was registered at www.clinicaltrials.gov as NCT01028898. RESULTS: Twenty-five polymorphic sites of MT-ATP 6 and 8 genes were detected and 12 of them were missense mutations. A median of two polymorphic sites in MT-ATP genes was found in colon specimens of controls while a median of three polymorphic sites was noted in patients with IBS-D (Mann-Whitney test, P=0.012). The variants of the colon and ileum speci-mens from the same subjects were identical in all but one case. Symptom duration in IBS was not found to be a significant factor associated with the mtDNA polymorphism (Spearman correlation, P=0.592). The mitochondrial DNA change at 8860 was present in all cases of both groups. The frequency of the 8701 poly-morphism was found to be the second most frequent; however, no statistical difference was noted between the groups (χ2 test, P=0.584). CONCLUSION: Patients with IBS-D have a higher inci-dence of MT-ATP 6 and 8 polymorphisms than healthy subjects, implying that the mtDNA polymorphism may play a role in IBS-D.展开更多

Methods: In this double-blind randomized controlled study, patients aged 65 to 80 who were undergoing spinal fusion surgery for disc herniation were administered flurbiprofen 100 mg (P group, flurbiprofen group), prednisolone 0.6 mg/kg (D group, prednisolone group), prednisolone 0.6 mg/kg plus flurbiprofen 100 mg (P + D group, flurbiprofen + prednisolone group) or normal saline (S group, saline group) 15 minutes before the induction of anesthesia. Plasma samples were collected before surgery (T0) and on day 1 (T1), day 2 (T2) and day 3 (T3) following surgery. At the same time, systemic inflammatory response syndrome (SIRS) was assessed by SIRS criteria. The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) for collected samples were measured. Results: Other groups had significantly lower levels of IL-6, CRP and occurrence of SIRS than S group (p < 0.05). Compared to groups P and D, the levels of IL-6 and CRP in P + D group were significantly lower on T1 (p < 0.05). Peak levels of IL-6 in all groups were presented on T1 (p 0.05). The levels of CRP within three days were significantly different but did not show peak levels (p > 0.05). Conclusion: Compared to prednisolone or flurbiprofen, combining flurbiprofen with prednisolone in elderly surgery patients led to an increased suppression of IL-6.展开更多

Methods: 115 cases of SIRS patients were divided into sepsis group(n=46) and non-infectious SIRS group(n=69). The serum levels of PCT, IL-6 were detected within 24 h of admission in two groups. White blood cell count (WBC), neutrophil counts (N), neutrophil percentage (N %), C - reactive protein (CRP) and acute physiology and chronic health evaluation (APACHEⅡ score), sequential organ failure score (SOFA score) were recorded.Results:APACHEⅡscore, SOFA score, hospital mortality had statistical differences between sepsis group and noninfectious SIRS group (P < 0.05). The serum levels of CRP、PCT、IL-6 and N% in sepsis group were higher than those in noninfectious SIRS group(P<0.05). PCT and IL - 6 were positively correlated with APACHEⅡ scores (r = 0.580, 0.463), N, N %, PCT, IL - 6 were positively correlated with SOFA scores (r = 0.371, 0.393, 0.371, 0.393), PCT was positively related with hospital mortality (r = 0.349). ROC curve analysis showed that compared with CRP, N, N% and other inflammatory markers, the AUC of PCT, il-6 and infection score was larger, and the value of diagnosis was higher.Conclusion:The combined detection of PCT and IL-6 is more effective than single detection in prognosis of sepsis.展开更多

文摘AIM: To investigate mitochondrial ATP 6 and 8 poly-morphisms in the colon and ileum of patients with ir-ritable bowel syndrome with diarrhea (IBS-D). METHODS: Twenty-eight patients fulfilling the Rome Ⅲ criteria for IBS-D and 28 healthy subjects were in-vestigated. All study participants underwent screening colonoscopy and mucosal biopsies were obtained from the colon and/or terminal ileum. Genomic DNA was ex-tracted from specimens based on standard protocols. Mitochondrial ATP (MT-ATP) 6 and 8 genes in speci-mens were polymerase chain reaction amplified and sequenced. Sequencing data were analyzed via Variant Reporter Software and compared with the reference sequence from Genbank (accession No. NC_012920) to indicate possible polymorphisms. The protocol was registered at www.clinicaltrials.gov as NCT01028898. RESULTS: Twenty-five polymorphic sites of MT-ATP 6 and 8 genes were detected and 12 of them were missense mutations. A median of two polymorphic sites in MT-ATP genes was found in colon specimens of controls while a median of three polymorphic sites was noted in patients with IBS-D (Mann-Whitney test, P=0.012). The variants of the colon and ileum speci-mens from the same subjects were identical in all but one case. Symptom duration in IBS was not found to be a significant factor associated with the mtDNA polymorphism (Spearman correlation, P=0.592). The mitochondrial DNA change at 8860 was present in all cases of both groups. The frequency of the 8701 poly-morphism was found to be the second most frequent; however, no statistical difference was noted between the groups (χ2 test, P=0.584). CONCLUSION: Patients with IBS-D have a higher inci-dence of MT-ATP 6 and 8 polymorphisms than healthy subjects, implying that the mtDNA polymorphism may play a role in IBS-D.

PCT and IL - 6 were positively correlated with APACHEⅡ scores (r = 0.580, 0.463), N, N %, PCT, IL - 6 were positively correlated with SOFA scores (r = 0.371, 0.393, 0.371, 0.393), PCT was positively related with hospital mortality (r = 0.349). ROC curve analysis showed that compared with CRP, N, N% and other inflammatory markers, the AUC of PCT, il-6 and infection score was larger, and the value of diagnosis was higher.Conclusion:The combined detection of PCT and IL-6 is more effective than single detection in prognosis of sepsis.
文摘The TRPM6 gene is associated with multifactorial diseases:diabetes mellitus,obesity,hypertension,components of the metabolic syndrome.The aim of this study is to test the association between TRPM6 rs2274924 gene,metabolic syndrome and S.aureus based on clinical data and biochemical,haematological,microbiological and genetic laboratory investigations in patients with type 2 diabetes mellitus.The TRPM6 gene sequencing was performed by the Advanced NGx assay based on clinical and laboratory data,on 152 subjects from Giurgiu County Emergency Hospital.The results were processed by the graph Pad prism 7 program,VMD.In conclusion,the TRPM6 rs2274924 gene is associated with metabolic syndrome and S.aureus.
