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.
ObjectiveTo explore the correlation of serum neutrophil gelatinase-associated lipocalin (sNGAL) with inflammatory response in patients with community-acquired pneumonia (CAP) and assess the diagnostic value of sNGAL for severe CAP (SCAP).MethodsFrom January 2018 to June 2019, a total of 85 patients with CAP were enrolled in this study. Age, length of hospital stay, the levels of serum creatinine, blood urea nitrogen, white blood cell count,C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin, and CURB-65 score were compared between patients with SCAP (n=34) and patients without SCAP (n=51). The correlations of sNGAL with serum creatinine, blood urea nitrogen, white blood cell count, CRP, IL-6, procalcitonin, and CURB-65 score were assessed with Spearman’s correlation analysis. The area under the receiver operating characteristic (ROC) curve for sNGAL diagnosing SCAP was examined. ResultsCompared with patients without SCAP, SCAP patients demonstrated older age, longer hospital stay, higher serum CRP and IL-6 concentritions, and higher CURB-65 score (P<0.05). The Spearman’s correlation test showed that sNGAL was positively correlated with serum CRP, IL-6, PCT and CURB-65 score (rs=0.472, 0.504, 0.388, and 0.405, respectively; P<0.01). According to ROC analysis, the area under curve of sNGAL for diagnosing SCAP were 0.816, with a sensitivity of 76.56% and a specificity of 74.4% when the cut-off value was 171.0 ng/mL.ConclusionssNGAL concentration is positively correlated with the serverity of CAP. It can be regarded as a reliable indicator for diagnosis of SCAP in patients with CAP.
Objective To determine the role of serum cystatin C in evaluating the severity and predicting in-hospital mortality in patients with community-acquired pneumonia (CAP). Methods The clinical data of 176 patients with CAP treated between January 2015 and October 2016 were collected in a retrospective way. The CURB-65 score was used to assess the severity. The serum levels of cystatin C and C-reactive protein (CRP) on admission were measured. The correlations between cystatin C and CURB-65 score and between cystatin C and CRP were calculated. Receiver operating characteristic curve was used to determine the ability of cystatin C in predicting in-hospital mortality. Results The serum level of cystatin C increased with the increasing CURB-65 score (P<0.001). The serum level of cystatin C was correlated positively with CRP level (rs=0.190, P<0.011). There were 22 patients died in hospital, the mean serum cystatin C level of non-survivor was significantly higher than that of survivors [(1.51±0.56)vs. (1.02±0.29) mg/L, P<0.001]. At a cut-off 1.18 mg/L, the sensitivity and specificity of cystatin C in predicting in-hospital mortality were 68.18% and 81.17%, respectively. The area under the receiver operating characteristic curve was 0.793. The combination of cystatin C and CRP increased the predictive accuracy for in-hospital mortality. Conclusion Cystatin C level increases with the increaseing severity of CAP, and it may be a clinical biomarker to evaluate the severity and prognosis of patients with CAP.
Objective To explore the characteristics and the related factors of the lipid profiles in patients with ankylosing spondylitis (AS). Methods Sixty AS patients and 60 healthy controls were included retrospectively from January 2005 to January 2015. Information including general data, physical examination, and blood sample were collected; triacylglycerol (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), high-density lipoprotein cholesterol (HDL-C), and C-reactive protein (CRP) were assessed. Results TG increased in 46.7% (28/60) patients, and HDL-C decreased in 50.0% (30/60). Compared with the control group, AS patients had lower levels of HDL-C, TC and LDL-C, and higher levels of TG, VLDL-C, VLDL-C/LDL-C ratio, LDL-C/HDL-C ratio, and TC/HDL-C ratio; the differences above were all statistically significant (P<0.01). Spearman correlation test demonstrated that HDL-C level was correlated negatively with serum CRP (rs=–0.359, P=0.005). Multiple linear regression model demonstrated that CRP was associated with HDL-C in AS patients (P=0.019). Conclusions Dyslipoproteinemia is a common feature in AS patients. The main characteristic is the increase of TG and decrease of HDL-C, related with inflammation. It suggests a high risk of atherosclerosis.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
Objectives This study aims to examine the possible association between C-reactive protein (CRP) concentration and cognitive impairment in patients with post-stroke epilepsy. Methods Patients with post-stroke epilepsy admitted to Western China Hospital from January 2010 to June 2016 were consecutively enrolled in our study. CRP levels were assessed within one week of stroke onset, and then correlated with cognitive status assessed two years after stroke using the Six-Item Screener. Results Among the 96 patients with post-stroke epilepsy who included in our study, 24 patients were found to have cognitive impairment during the two years follow-up period. Our data showed a significant association between CRP levels and cognitive performance in these patients (31.5±36.2 vs. 11.9±19.4, P=0.029). In addition, this association persisted even after adjusting for potential confounders［OR=1.021, 95%CI (0.997, 1.206), P=0.037］. Conclusions Following ischemic stroke, higher CRP levels is associated with subsequent cognitive decline in patients with epilepsy. Association and prospective studies in larger sample size are needed in order to validate our findings, especially studies in which baseline CRP level and CRP level during follow-up are closely monitored.
Objective To investigate the values of pneumonia severity index ( PSI) , CURB-65,plasma procalcitonin ( PCT) , C-reactive protein ( CRP) measurements for evaluation the severity of healthcare-associated pneumonia ( HCAP) .Methods A retrospective observational study was conducted on 92 hospitalized patients with HCAP admitted between June 2010 and December 2011. They were divided into different groups according to different severity assessment criteria. The variance and correlation of PCT,CRP,WBC and percent of neutrophil ( Neu% ) levels were compared among different groups. ROC curvewas established to analyze PSI, CURB-65, PCT and CRP levels for predicting the motality of HCAP patients.Results In the severe HCAP group, PSI and CURB-65 scoring and serum PCT, CRP, WBC, Neu% levels were significantly higher than those in the non-severe HCAP group( P lt; 0. 05) . In the high-risk HCAP group, PCT, CRP, WBC and Neu% levels were significantly higher than those in the low-risk HCAP group according to the PSI and CURB-65 scoring criteria( P lt;0. 05) .WBC and Neu% levels were also significantly higher than those in the moderate-risk group. PSI and CURB-65 scoring were positively correlated with PCT and CRP levels. PSI scoring gt;120 points or CURB-65 scoring gt;2 points on admission were predictors of mortality. Conclusions PSI and CURB-65 scoring are correlated with severity of HCAP. Combining serum PCT and CRP levels can improve the predictive accuracy of the severity of HCAP.
ObjectiveTo explore the changes of plasma prealbumin (PA), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) levels before and after treatment in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and analyze the correlation of PA and Hcy with hs-CRP and body mass index (BMI).MethodsA total of 132 hospitalized AECOPD patients with GOLD lung function as grade III-IV were recruited as an experimental group and 45 healthy subjects as a control group. The levels of plasma PA, Hcy and hs-CRP were measured by automatic biochemical analyzer, and the main indexes of pulmonary function were determined in all subjects.ResultsCompared with the control group, the level of plasma PA before and after treatment in the experimental group decreased significantly [(146.49±36.53) mg/L and (219.60±41.29) mg/L vs. (269.48±42.63) mg/L], the level of plasma Hcy before and after treatment increased significantly [(16.44±5.21) μmol/L and (12.61±4.56) μmol /L vs. (10.13±3.25) μmol/L], and the levels of plasma hs-CRP before and after treatment increased significantly [(45.24±29.94) mg/L and (7.71±3.41) mg/L vs. (5.01±1.52) mg/L] (all P<0.05). The levels of plasma PA, Hcy and hs-CRP after treatment were significantly better than before treatment in the experimental group (allP<0.01). The plasma PA values before and after treatment were negatively correlated with the level of hs-CRP before and after treatment, and positively correlated with BMI (bothP<0.05).ConclusionsThe levels of plasma PA, Hcy and hs-CRP are significantly different before and after the treatment in AECOPD patients and the healthy controls. PA is negatively correlated with hs-CRP and positively correlated with BMI. The detection of plasma PA and Hcy can help to determine the condition and efficacy of patients with COPD, and PA can reflect the level of inflammation and nutritional status to a certain extent.
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.
