Comparative analysis of Nε-carboxymethyl-lysine and inflammatory markers in diabetic and non-diabetic coronary artery disease patients

BACKGROUND Coronary artery disease(CAD)is a major cause of death worldwide,and India contributes to about one-fifth of total CAD deaths.The development of CAD has been linked to the accumulation of Nε-carboxymethyl-lysine(CML)in heart muscle,which correlates with fibrosis.AIM To assess the impact of CML and inflammatory markers on the biochemical and cardiovascular characteristics of CAD patients with and without diabetes.METHODS We enrolled 200 consecutive CAD patients who were undergoing coronary angiography and categorized them into two groups based on their serum glycosylated hemoglobin(HbA1c)levels(group I:HbA1c≥6.5;group II:HbA1c<6.5).We analyzed the levels of lipoproteins,plasma HbA1c levels,CML,interleukin-6(IL-6),tumor necrosis factor alpha(TNF-α),and nitric oxide.RESULTS Group I (81 males and 19 females) patients had a mean age of 54.2 ± 10.2 years, with a mean diabetes duration of4.9 ± 2.2 years. Group II (89 males and 11 females) patients had a mean age of 53.2 ± 10.3 years. Group I had moresevere CAD, with a higher percentage of patients with single vessel disease and greater stenosis severity in the leftanterior descending coronary artery compared to group II. Group I also exhibited a larger left atrium diameter.Group I patients exhibited significantly higher levels of CML, TNF-α, and IL-6 and lower levels of nitric oxide ascompared with group II patients. Additionally, CML showed a significant positive correlation with IL-6 (r = 0.596,P = 0.001) and TNF-α (r = 0.337, P = 0.001) and a negative correlation with nitric oxide (r=-4.16, P = 0.001). Oddsratio analysis revealed that patients with CML in the third quartile (264.43-364.31 ng/mL) were significantlyassociated with diabetic CAD at unadjusted and adjusted levels with covariates.

Prognostic performance of interleukin-10 in patients with chest pain and mild to moderate coronary artery lesions an 8-year follow-up study

Background Interleukin （IL）-10, IL-6 and their ratio （IL-6/IL-10） play an important role in the risk of developing coronary artery disease, and may correlate with its outcomes. Few clinical trials have investigated the prognostic impact of these factors on long-term car- diovascular events in patients presented with chest pain. Methods A prospective study was performed on 566 patients admitted with chest pain and identified mild to moderate coronary artery lesions. 1L-10, IL-6 and IL-6/IL-10 were measured. Results A total of 511 patients com- pleted the follow-up. The median follow-up time was 74 months. Kaplan-Meier analysis demonstrated a clear increase of the incidence of major adverse cardiac events during the follow-up period in patients with below-median levels of IL-10 （P = 0.006） and above-median levels of IL-6/IL-10 （P = 0.012）. Multivariate Cox proportional hazards analysis indicated the IL-10 levels to be strong independent predictors after adjustment for underlying confounders. Conclusions Elevated IL-10 levels are associated with a more favorable long-term prognosis in patients with chest pain and mild to moderate coronary artery lesions. IL-10 could be used for early risk assessment of long-term prognosis.

Objective: To investigate the effect of ultrasound-guided pleural paravertebral block combined with general anesthesia on serum monocyte chemokinin-1 (McP-1), interleukin-6 (il-1) and il-10 levels in patients with early breast cancer after modified radical mastectomy. Methods: A total of 76 patients with early breast cancer from October 2015 to July 2018 were selected from our hospital and divided into study group (n=38) and control group (n=38). The control group received general anesthesia, and the study group received ultrasound-guided paravertebral block combined with general anesthesia. Data of two groups of perioperative situation (PCIA press the number, volume of intraoperative sufentanil and PACU time), preoperative and postoperative 12 h, 24 h serum factor (MCP-1, IL-6, IL-10) level, after 2 h, 4 h, 8 h, 12 h, 24 h when pain (VAS) score, preoperative (T1), 15 min after the anesthesia (T2), 5 min after surgery (T3) hemodynamic state [heart rate (HR), mean arterial pressure (MAP)], the incidence of adverse reactions were counted. Results: (1) Perioperative status: PCIA presses, intraoperative dose of sufentanil and PACU duration in the study group were less than those in the control group. (2) Serum factors: there was no significant difference in serum McP-1, il-6 and il-10 levels between the two groups before operation. The serum levels of McP-1, il-6 and il-10 in the two groups 12 h after operation were higher than those before operation. The serum levels of McP-1, il-6 and il-10 in the two groups at 24 h after surgery were significantly lower than those at 12 h after surgery, and the serum levels of McP-1, il-6 and il-10 in the group at 12 h and 24 h after surgery were lower than those of the control group. (3) Pain degree: the VAS score of the study group at 2 h, 4 h, 8 h, 12 h and 24 h after surgery was lower than that of the control group. (4) Hemodynamics: there was no significant difference in HR and MAP between the two groups during T1, HR and MAP in T2 were lower than those in T1, but the level of each indicator in the study group was higher than that in the control group. (5) Adverse Reactions: the incidence of adverse reactions was lower in the study group (10.53%) than in the control group (28.95%). Conclusion: The application of ultrasound guided early breast cancer modified radical block complex general anesthesia thoracic vertebra, can reduce the dosage of anesthetic drugs, shorten the PACU, residence time, reduce postoperative pain, maintain stable hemodynamic state, inhibiting inflammatory reaction caused by surgical trauma degree, and can reduce the incidence of adverse reactions, and has safety.

Relationship between coronary atherosclerosis plaque characteristics and high sensitivity C-reactive proteins, interleukin-6

Background The relationship between inflammatory markers and the characteristics of coronary atherosclerosis plaques is uncertain. The aim of the present study was to evaluate the relationship between the characteristics of coronary atherosclerosis plaques and inflammatory markers such as high sensitivity C-reactive proteins （Hs-CRP） and interleukin-6 （IL-6）. Methods All patients suspected of having coronary heart disease （CHD） underwent Siemens 64-slice CT angiography （64-SCTA） to distinguish the quality of plaque of coronary artery lesions. Blood samples were taken to measure levels of serum Hs-CRP and IL-6 in different plaque groups and the control group and compared with the value of 64-SCTA for detection of coronary artery plaque. Results The sensitivity of detecting coronary artery plaque by 64-SCTA was 87.4%, the specificity was 87.1%, the positive predictive value was 82.2%, and the negative predictive value was 91.0%. Comparing the levels of serum Hs-CRP and IL-6 among plaque groups, the mean levels of serum Hs-CRP and IL-6 in three plaque groups were significantly higher than those in the control group （P 〈0.01）. The mean levels of serum Hs-CRP and IL-6 in the soft plaque group and mixed plaque group were significantly higher than those in hard plaque group （P〈0.01）. Plaque burden in the soft plaque group and mixed plaque group was significantly higher than in the hard plaque group （P 〈0.01）, but there was no statistical difference between the soft plaque group and mixed plaque group （P=-0.246）. There was a negative correlation between the CT scale and Hs-CRP and IL-6 levels in the soft plaque group （r= -0.621, P〈0.01, and r= -0.593, P 〈0.01 respectively）. There was a positive correlation between the plaque burden and Hs-CRP and IL-6 levels in the soft plaque group （r=0.579, P〈0.05 and r=0.429, P〈0.05 respectively）. Conclusions 64-SCTA is an effective way to distinguish the different quality of coronary atherosclerosis plaque. Serum Hs-CRP and IL-6 levels can be considered as the indexes to judge the degree of CHD and may reflect the activity of plaque in CHD patients. Thus it is important for clinical diagnosis and risk evaluation of acute coronary syndrome （ACS） patients.

Nuclear factor kB activity in patients with acute severe cholangitis

AIM: To determine the NF-kB activity in peripheral blood mononuclear cells (PBMC) in patients with acute cholangitis of severe type (ACST) and correlate the degree of NF-kB activation with severity of biliary tract infection and clinical outcome. METHODS: Twenty patients with ACST were divided into survivor group (13 cases) and nonsurvivor group (7 cases). Other ten patients undergoing elective gastrectomy or inguinal hernia repair were selected as control group. Peripheral blood samples were taken 24 hours postoperatively. PBMC were separated by density gradient centrifugation, then nuclear proteins were isolated from PBMC, and Electrophoretic Mobility Shift Assay (EMSA) used determined. The results were quantified by scanning densitometer of a Bio-Image Analysis System and expressed as relative optical density (ROD). The levels of TNF-alpha, IL-6, and IL-10 in the plasma of patients with ACST and healthy control subjects were determined by using an enzyme-linked immunoassay (ELISA). RESULTS: The NF-kB activity was 5.02 +/- 1.03 in nonsurvivor group, 2.98 +/- 0.51 in survivor group and 1.06 +/- 0.34 in control group. There were statistical differences in three groups (P【0.05). The levels of TNF-alpha and IL-6 in plasma were (498 +/- 53)ng.L(-1)and (587 +/- 64)ng.L(-1)in nonsurvivor group, (284 +/- 32)ng.L(-1) and (318 +/- 49)ng.L(-1)in survivor group and (89 +/- 11)ng.L(-1) and (102 +/-13)ng.L(-1)in control group. All patients with ACST had increased levels of TNF-alpha and IL-6, which were many-fold greater than those of control group, and there was an evidence of significantly higher levels in those of nonsurvivor group than that in survivor group (P【0.05). The levels of IL-10 in plasma were (378+/-32)ng.L(-1), (384+/-37)ng.L(-1) and (68+/-11)ng.L(-1) in three groups, respectively. All patients had also increased levels of IL-10 when compared with control group (P【0.05), but the IL-10 levels were not significantly higher in nonsurvivors than in survivors (P】0.05). CONCLUSION: NF-kB activity in PBMC in patients with ACST increases markedly and the degree of NF-kB activation is correlated with severity of biliary tract infection and clinical outcome.
