Objective To determine the influence and significance of combinative assessment of 64 multi-slice spiral computed tomography (MSCT) with serum amyloid A protein (SAA) or C-reactive protein (CRP) on the selection of operative procedures of rectal cancer under the multi-disciplinary team. Methods Prospectively enrolled patients diagnosed definitely as rectal cancer at West China Hospital of Sichuan University from February to August 2009 were randomly assigned into two groups. In one group named MSCT+SAA group, both 64 MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT+CRP group, both MSCT and CRP combinative assessment were made for preoperative evaluation. Furthermore, the preoperative staging and predicted operation procedures were compared with postoperative pathologic staging and practical operation procedures, respectively, and the relationship between the choice of operation procedures and clinicopathologic factors was analyzed. Results All 165 patients were randomly assigned into MSCT+SAA group (n=83) and MSCT+CRP group (n=82). The baseline characteristics of two groups were statistically similar (Pgt;0.05). For MSCT+SAA group, the accuracies of preoperative staging T, N, M and TNM were 74.7%， 68.7%, 100% and 66.3%, respectively. For MSCT+CRP group, the accuracies of preoperative staging T, N, M and TNM were 72.0%, 86.6%, 100% and 81.7%, respectively. There were statistically significant differences in the accuracies of N staging and TNM staging between two groups (P＜0.05). However, there was no statistically significant difference of the accuracy of prediction to operative procedures between two groups (90.4% vs. 95.1%, Pgt;0.05). The pathological T staging (P＜0.001), N staging (P＜0.001), TNM staging (P＜0.001), preoperative serum level of SAA (P=0.010), serum level of CRP (P=0.042), and distance of tumor to the dentate line (P=0.011) were associated with the operative procedures. Conclusion Combinative assessment of MSCT+CRP could improve the accuracy of preoperative staging and operative procedures prediction, which may be superior to MSCT+SAA.
Objective To investigate the evaluation value of serum interleukin-34 (IL-34), macrophage migration inhibitor (MIF), osteopontin (OPN) and hypersensitive C-reactive protein (hs-CRP) in the diagnosis and prognosis of active pulmonary tuberculosis. Methods Clinical data of 100 patients with active pulmonary tuberculosis admitted from June 2019 to June 2022 were selected as an observation group and retrospectively analyzed. All patients received standardized anti-tuberculosis therapy for 6 months and were divided into a good prognosis group (76 cases) and a poor prognosis group (24 cases) according to the prognosis. Another 80 healthy volunteers who underwent physical examination during the same period were selected as the control group. Serum levels of IL-34, MIF, OPN and hs-CRP were detected in each group, and the value of serum IL-34, MIF, OPN and hs-CRP in the diagnosis and prognosis of active pulmonary tuberculosis was analyzed by receiver operating characteristic curve (ROC curve). Results Serum levels of IL-34, MIF, OPN and hs-CRP in the observation group were higher than those in the control group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain diagnostic value in active pulmonary tuberculosis, with area under ROC curve (AUC) of 0.864, 0.870, 0.865, and 0.880, respectively (all P<0.01), and the combination of the four indexes had a higher diagnostic value (AUC=0.902, P<0.01). Serum levels of IL-34, MIF, OPN and hs-CRP in the good prognosis group were lower than those in the poor prognosis group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain value in evaluating the prognosis of active pulmonary tuberculosis, with AUC of 0.850, 0.874, 0.837, and 0.842, respectively (all P<0.01), and the combined value of the four indexes was higher (AUC=0.923, P<0.01). Conclusion The combined detection of serum IL-34, MIF, OPN and hs-CRP has high value in the diagnosis and prognosis assessment of active pulmonary tuberculosis.
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 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.
ObjectiveTo observe the relationship of serum tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), and C-reactive protein (CRP) with obstructive sleep apnea hypopnea syndrome (OSAHS) associated pulmonary hypertension (OSAHS-PH). MethodsFrom September 2013 to October 2014, 38 OSAHS patients, 32 OSAHS-PH patients and 35 healthy subjects were enrolled from the General Hospital of Ningxia Medical University. OSAHS was diagnosed by polysomnography. The pulmonary artery systolic pressure (PASP) was measured by echocardiograph, and the diagnose criteria for pulmonary hypertension was PASP≥40 mm Hg. Serum TNF-α, IL-6, CRP and endothelin 1 (ET-1) were detected by enzyme-linked immunosorbent assay. The correlation between TNF-α, IL-6, CRP, ET-1 and PASP was analyzed. ResultsThe serum levels of TNF-α, IL-6, CRP and ET-1 were remarkably different among three groups (F=55.34, 25.05, 23.85, 34.06 respectively; all P < 0.05). The levels of TNF-α, IL-6, CRP and ET-1 in the OSAHS group were higher than those in the healthy group, and lower than those in the OSAHS-PH group (all P < 0.05). The PASP was positively correlated with the levels of the four factors (r=0.755, 0.762, 0.747, 0.759 respectively; all P < 0.01). ConclusionThe levels of serum TNF-α, IL-6 and CRP are correlated with pulmonary hypertension and they may be involved in the process of OSAHS-PH.
Objective To explore the value of fecal calprotectin （FCP） in the activity evaluation for ulcerative colitis （UC）. Methods Sixty three patients with UC （UC group） and 30 patients with gastrointestinal symptoms but without abnormal results of colonoscopy （control group）， who were treated in The Forth Affiliated Hospital of China Medical University between Sep. 2007 to Dec. 2009 were enrolled to examine the FCP， C-creative protein （CRP）， and erythrocyte sedimentation rate （ESR）. Then comparison between UC group and control group was performed. Results Levels of FCP and CRP in active gradeⅠ，Ⅱ， and Ⅲ group were all significantly higher than those of control group and inactive UC group （P＜0.05）， with the increase of active grade of UC， the level of FCP gradually increased （P＜0.05）. The levels of CRP in active grade Ⅱ and Ⅲ group were all significantly higher than those of gradeⅠgroup （P＜0.05）， but didn’t differed between active grade Ⅱ and Ⅲ group （P＞0.05）. There were no significant difference among 5 groups on ESR （P＞0.05）. Levels of FCP （rs=0.807， P＜0.01）， CRP（rs=0.651， P＜0.01）， and ESR （rs=0.371， P＜0.05） in active grade group were significantly related to histological grade under colonoscopy. Conclusion FCP examination is simple， inexpensive， repeatable， and noninvasive， and FCP can be used as an marker of activity evaluation in UC.

SerumIL-10 level in OSAHS patients was correlated negatively with AHI ( r = - 0. 722, P lt; 0. 01) and positively with LSpO2 ( r = 0. 564, P lt; 0. 01) and MSpO2 ( r = 0. 505, P lt; 0.01) . ④ After three months of auto continuous positive air pressure( Auto-CPAP) or uvulopalatopharyngoplasty( UPPP) treatment, serum 8-isoPG, LTB4, TNF-α, and Hs-CRP levels of the OSAHS patients after sleep were obviously decreased [ ( 23. 10 ±9. 54) ng/L, ( 4. 02 ±2. 15) μg/L, ( 810. 25 ±135. 85) ng/L, ( 0. 79 ±0. 60) mg/L, respectively] , and serum IL-10 level was obviously increased[ ( 6. 93 ±3. 91) ng/L] ( P lt; 0. 01) . ⑤ serum 8-isoPG and IL-10 had no statistics difference and serum LTB4, TNF-α, Hs-CRP levels were higher in OSAHS underwent therapy compared with the normal controls. Conclusions The results suggest that inflammation and oxidative stress are activated and antiflammatory cytokines are decreased in the OSAHS patients. The serum levels of 8-isoPG, LTB4 , TNF-α, Hs-CRP and IL-10 may prove to be useful in severity monitoring and intervention efficacy judgement in OSAHS patients.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
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.
