Objective To explore the possible anti-inflammatory mechanism of intensive insulin therapy （IIT） by studying the effect of IIT on the levels of TNF-α, IL-6, C-reactive protein （CRP） and APACHE Ⅱ score in biliary pyemia. Methods Twenty eight patients with biliary pyemia who were admitted by our department and given an operation within 24 h form Jan. 2005 to Dec. 2008 were randomly divided into two groups by using random number table numbers: one group treated with IIT （IIT group, n=14） and another group treated with routine insulin therapy （RIT group, n=14）. The inflammatory factors, such as TNF-α, IL-6 and CRP were detected dynamically and the APACHEⅡ score was calculated. ResultsThe level of CRP and APACHEⅡ score on day 5 and 7 and the levels of TNF-α and IL-6 on day 3, 5 and 7 after operation in IIT group were significantly lower than those in RIT group （P＜0.05, P＜0.0１）. Compared with preoperative levels, the IL-6 and APACHEⅡ score in IIT group commenced to decrease on day 3 after operation （P＜0.05）, that was earlier than control group. Conclusion The treatment with IIT can suppress the composition of TNF-α, IL-6 and CRP, protect impaired hepatic cells, and reduce APACHEⅡ score, the degree of systemic inflammation and incidence of MODS.
ObjectiveTo investigate the pathogenesis and treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) by detecting the changes of serum interleukin-23 (IL-23) and C-reactive protein (CRP) levels of the OSAHS patients before and after treatment with continuous positive airway pressure (CPAP).MethodsFifty-eight patients with moderate to severe OSAHS diagnosed by polysomnography were recruited as an experimental group, 57 out-patient healthy subjects with matched age, sex and body mass index of the experimental group were enrolled as a control group. The serum concentrations of IL-23 and CRP in the experimental group were detected and compared before and after CPAP application for 3 months. The serum concentrations of IL-23 and CRP in the control group were also measured.ResultsThe serum levels of IL-23 and CRP in the OSAHS patients were significantly higher than those in the normal control subjects (P<0.05). The serum levels of IL-23 and CRP in the OSAHS patients after CPAP treatment were significantly lower than those before CPAP treatment (P<0.05). The serum concentrations of IL-23 and CRP were positively correlated with apnea hypopnea index (r=0.756, r=0.345, P<0.05, respectively), and negatively correlated with mean oxygen saturation (r=–0.715, r=–0.334, P<0.05, respectively).ConclusionsThe serum levels of IL-23 and CRP are positively correlated with the severity of OSAHS. After CPAP treatment, the levels of IL-23 and CRP decrease, which indicates that CPAP treatment may reduce the inflammatory reaction and correct anoxia of OSAHS patients.
Objective To determine the effectiveness of statins in reducing C-reactive protein in patients with cerebral infarction and the potency of C-reactive protein as an indicator for preventing cerebrovascular events. Methods We searched PubMed, EMbase, Central Register of Controlled Trials, CBMdisc and CNKI from the date of establishment through August 2008. Bibliographies of the retrieved articles were also checked. Data was extracted and evaluated by two reviewers independently with a designed extraction form. The RevMan 5.0 software was used to carry out meta-analysis. Results Twenty-three randomized trials involving 1946 patients were included. The results of meta-analyses showed the following: statins reduced C-reactive protein compared to the control group (WMD= –5.79, 95%CI –7.32 to –4.26); statins were associated with a reduction of carotid intima-media thickness (IMT) (WMD= –0.21, 95%CI –0.25 to –0.17); atorvastatin greatly reduced C-reactive protein than the simvastatin control group (WMD= –1.78, 95%CI –3.92 to 0.36); statins were associated with a slight improvement in neurological deficit (OR= 2.22, 95%CI 0.94 to 5.21). Conclusion The evidence currently available shows that statins can reduce C-reactive protein and carotid IMT in the patients with cerebral infarction compared to the control group. However, it is not clear whether statins reducing C-reactive protein is correlated to the improvement of neurological deficit and prognosis. Similar trials in future should focus on the relationship between the change of C-reactive protein and clinical outcomes.
ObjectiveTo investigate the correlation between hyperreflective dots (HRD) and lipid levels and systemic inflammatory factors in patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO).MethodsA cross-sectional clinical study. From December 2016 to June 2020, 118 eyes of 118 patients with retinal vein occlusion diagnosed in the Department of Ophthalmology, Central Theater Command Hospital of People's Liberation Army were included in the study. Among them, 67 cases of BRVO and 51 cases of CRVO were divided into CRVO group and BRVO group accordingly. Peripheral venous blood was drawn from the patients within 3 days after the eye examination to detect the percentage of neutrophils, monocytes, hypersensitive C-reactive protein (CRP), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and lipoprotein(a). The ratio of monocytes to high-density lipoprotein (MHR) was also calculated. The 3D OCT-2000 instrument from Topcon (Japan) was used to measure the central retinal thickness (CRT) and the numbers of HRD. According to the different distribution position, HRD is divided into inner retina HRD, outer retina HRD, and total retina HRD.The independent sample t test was used to compare the continuous variables of the two groups, and the χ2 test was used to compare the rates. The correlation between HRD counts and blood lipid levels and peripheral blood inflammation indicators in patients with different types of RVO was analyzed by Spearman correlation analysis.ResultsThe average age of patients in the BRVO group and CRVO group were 60.1±9.5 and 53.6±15.7 years, respectively; the prevalence of hypertension was 53.7% (36/67) and 24.5% (12/51), respectively. Comparison of age (t=2.634) and prevalence of hypertension (χ2=11.298) between the two groups showed statistically significant differences (P＜0.05). Gender (χ2=2.000), course of disease (t=－1.101), prevalence of diabetes (χ2=1.315), eye category (χ2=1.742), baseline visual acuity (t=1.792), intraocular pressure (t=0.708), CRT (t=1.318), and peripheral blood include the percentage of neutrophils, the absolute number of monocytes, CRP, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein(a), MHR (t=－0.559, 1.126, 0.579, 1.299, －0.134, 0.556, 1.230, －0.267, 0.483), the difference was not statistically significant. Correlation analysis showed that the HRD counts in the outer retina of BRVO patients were positively correlated with total cholesterol (r=0.289, P=0.036); the HRD in the inner retina and total HRD counts of CRVO patients were positively correlated with CRP (r=0.406, 0.343; P=0.004, 0.014). There was no correlation between HRD counts and percentage of neutrophils, absolute number of monocytes, triglycerides, high-density lipoprotein, low-density lipoprotein, lipoprotein(a), and MHR (P＞0.05).ConclusionThe number of HRD is related to the blood lipid level in BRVO patients and CRP (an inflammatory index) in CRVO patients.
Objective To investigate the expression and clinical significance of soluble triggering receptor expression on myeloid cells-1（sTREM-1） in sepsis patients.Methods Serum concentrations of sTREM-1，procalcitonin（PCT），tumor necrosis factor alpha（TNF-α） and interleukin-10（IL-10） were measured by enzyme-linked immunosorbent assay，while high sensitivity C-reactive protein （hsCRP） level was detected by immunoturbidimetry in 68 patients with sepsis，40 patients with no-infective SIRS，and 20 normal individuals. The diagnostic and prognostic value of sTREM-1 and its comparison with PCT and hsCRP were analyzed. The sequential organ failure assessment （SOFA） score system was used to evaluate the severity of sepsis. The relationship between sTREM-1, PCT , hsCRP , SOFA score，TNF-α ,and IL-10 of the sepsis patients was analyzed，respectively. Results The differences in the serum concentrations of sTREM-1，PCT，hsCRP，IL-10 and IL-10/TNF-α ratio had statistical significance among three groups（Plt;0.05）. The differences in the serum concentration of TNF-α had no statistical significance among three groups （Pgt;0.05）. However，the serum levels of sTREM-1，PCT and hsCRP in the sepsis group were significantly higher than those in the SIRS group （Plt;0.05）. The receiver operating characteristic curve （ROC） analysis showed the area under the curve （AUC） for sTREM-1，PCT and hsCRP were 0.772 （95%CI 0.674-0.871），0.718 （95%CI 0.601-0.835） and 0.664 （95%CI 0.532-0.797），respectively. The serum levels of sTREM-1 and PCT in the non-survivors were significantly higher than the survivors in the sepsis group （Plt;0.01），but the differences in the serum concentration of hsCRP had no statistical significance between the non-survivors and the survivors in the sepsis group （Pgt;0.05）. There were significantly positive correlations between sTREM-1 and SOFA score，IL-10 or IL-10/TNF-α ratio（r value of 0.453，0.301，0.417，Plt;0.05），but no correlation between sTREM-1 and TNF-α（Pgt;0.05）. There was significantly positive correlation between PCT and SOFA score （r=0.436，Plt;0.05），while no relationship between hsCRP and SOFA score（Pgt;0.05）. Conclusions The serum level of sTREM-1 not only be valuable in the diagnosis of sepsis，but also may be used as a prognostic marker in sepsis，as it can reflect the severity of sepsis in certain degree. Furthermore，sTREM-1 or PCT may be superior to hsCRP in diagnosis，prognostic judgment and severity assessment of sepsis.
ObjectiveTo explore the serum concentrations of complement C1q tumor necrosis factor related protein 5 (CTRP5) in patients with acute exacerbations and stable stage of chronic obstructive pulmonary disease (COPD), and analyze the correlation of CTRP5 with high sensitivity C-reactive protein (hs-CRP) and FEV1/FVC and FEV1%pred.MethodsThirty hospitalized patients with acute exacerbation of COPD and 30 outpatients with stable COPD according with diagnostic criteria and inclusive criteria were sampled successively. At the same time 30 healthy volunteers were selected as normal control. All subjects were measured the concentrations of CTRP5 and hs-CRP in serum and lung function test was performed.ResultsThe serum CTRP5 and hs-CRP concentrations of the acute exacerbation group was higher than those in the stable group and the control group. The serum CTRP5 and hs-CRP concentrations of the stable group was also higher than those of the control group. The FEV1/FVC of the acute exacerbation group was lower than those of the stable group and the control group; and the FEV1/FVC of the stable group was lower than that of the control group. The FEV1%pred of three groups by analysis indicated the difference was statistically significant. Further pairwise comparisons demonstrated that the FEV1%pred of two COPD groups were lower than that of the control group but the FEV1%pred of the acute exacerbation group and stable group was not significantly different. The correlation analysis of the acute exacerbation group and the stable group demonstrated that the levels of serum CTRP5 and hs-CRP were postively correlated and the level of serum CTRP5 was negatively correlated with FEV1/FVC and FEV1%pred.ConclusionsThe level of CTRP5 in serum of COPD patients is increased. No matter in acute exacerbation or stable phase, the level of serum CTRP5 is positively correlated with hs-CRP and negatively correlated with FEV1/FVC and FEV1%pred, which suggests that CTRP5 is involved in the pathogenesis of COPD but the exact mechanism needs further study.
ObjectiveTo investigate the relationship between preoperative C-reactive protein (CRP)/albumin ratio (CAR) and National Institutes of Health (NIH) risk classification in patients with gastric stromal tumors.MethodsClinical data of 108 patients with gastric stromal tumors admitted to the First Affiliated Hospital of Kunming Medical University from February 2010 to November 2016 were retrospectively collected. With the median of CAR as the critical value, patients were divided into high CAR group (CAR>0.048) and low CAR group (CAR≤0.048). Then observed the general clinicopathological characteristics and survival status of patients with higher and lower CAR value.ResultsThere were significant differences in NIH classification, tumor diameter, and mitosis between the high CAR group and low CAR group (P<0.05). Compared with the low CAR group, the tumors in the high CAR group had larger diameter, higher mitotic figure, and higher NIH grade. Survival analysis showed that the prognosis of the low CAR group was better than that of the high CAR group (χ2=15.152, P<0.001).ConclusionsCAR is closely related to the malignant index and NIH risk classification of gastric stromal tumors. It can be used as an index for evaluating the malignant degree of gastric stromal tumors, and it is expected to be an important reference factor for clinical NIH risk classification and prognosis.
Objective To measure the level of circulating endothelial progenitor cells ( EPCs) in peripheral blood of patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) , and to explore the relationship between EPCs and severity markers of the disease and cardiovascular adverse outcome predictors.Methods Forty patients with COPD were recruited, including 27 at acute exacerbation phase and 13 with stable COPD from December 2010 to December 2011. Sixteen healthy nonsmokers were included as controls. Circulating EPCs were isolated by Ficoll density-gradient centrifugation and purified by Magnetic Activated Cell Sorting system. High-sensitivity C-reactive protein ( hsCRP) was estimated by using a latex immunoturbidimetric assay kit, and matrix metalloproteinase-9 ( MMP-9) was measured by enzymelinked immunosorbent assay ( ELISA) . Arterial blood gas analysis and echocardiograph were performed in the AECOPD patients. The correlations between circulating EPCs, lung function, and cardiovascular markers were investigated. Results Circulating EPCs were significantly lower in AECOPD and stable COPD patients compared with the healthy controls [ ( 5.1 ±2.6) ×103 /mL and ( 6.0 ±3.2) ×103 /mL vs. ( 9.0 ±4.3) × 103 /mL, Plt;0. 05] . EPCs had a weak correlation with hsCRP ( P = 0. 033) , but not with MMP-9. In the AECOPD patients, EPC counts were significantly inversely correlated with PASP ( pulmonary artery systolic pressure) and NT-proBNP ( amino-terminal pro-brain natriuretic peptide) levels, and positively with left ventricular ejection fraction. No correlations were found between EPCs and lung function, blood gas, hospital stays or smoking index. Conclusions Circulating EPCs were significantly lower in AECOPD patients compared with healthy controls, in which systemic inflammation might be involved. Decreased EPCs were correlated with cardiac dysfunction in patients with AECOPD, which may account for the increased cardiovascular risk in this population.
In recent years, domestic and foreign scholars have carried out extensive research on the prognostic factors of gastric cancer. Among them, non-specific inflammatory markers and nutritional indicators are the most concentrated in gastric cancer. C-reactive protein, as an acute phase protein, has been widely used to diagnose acute and chronic inflammation throughout the body. Prealbumin is a sensitive indicator of nutrition with a shorter half-life, which can quickly reflect the nutritional status of the body. At present, C-reactive protein and prealbumin as sensitive indicators of inflammation and nutrition, have shown certain predictive value in terms of postoperative complications and prognosis of gastric cancer. This article reviews the use of C-reactive protein, prealbumin and their ratios in predicting postoperative complications and prognosis of gastric cancer, aiming to provide a reference for the diagnosis and treatment of patients after gastric cancer.
ObjectiveTo explore the association between frailty and in-hospital mortality in older patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods Elderly patients who were hospitalized with AECOPD from June 2022 to December 2022 at a large tertiary hospital were selected. The independent prognostic factors including frailty status were determined by multivariate logistic regression analysis. Mediation effect analysis was used to evaluate the mediating relationships between C-reactive protein (CRP) and albumin and in-hospital death. ResultsThe training set included 1 356 patients (aged 86.7±6.6), 25.0% of whom were diagnosed with frailty. The multiple logistic regression analysis showed that frailty, mean arterial pressure, Charlson comorbidity index, neutrophil–lymphocyte ratio, interleukin-6, CRP, albumin, and troponin T were associated with in-hospital mortality. Furthermore, CRP and albumin mediated the associations between frailty and in-hospital mortality. ConclusionFrailty may be an adverse prognostic factor for older patients admitted with an AECOPD. CRP and albumin may be parts of mechanism between frailty and in-hospital death.
