ObjectiveTo investigate the relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2) level and in-hospital prognosis in patients with acute type A aortic dissection within 24 hours of admission.MethodsFortysix patients diagnosed with type A aortic dissection were included in our hospital and their Lp-PLA2 levels within 24 hours of admission were measured between January 2017 and June 2019. According to their Lp-PLA2 levels within 24 hours of admission, 23 patients were classified into a high Lp-PLA2 group (Lp-PLA2 > 200 μg/L, 16 males and 7 females at age of 52.0±14.0 years) and 23 patients were into a low Lp-PLA2 group (Lp-PLA2 ≤200 μg/L, 15 males and 8 females at age of 53.0±11.0 years). The relationship between Lp-PLA2 level and clinical outcome was analyzed.ResultsThe incidences of bleeding, hospital infection, multiple organ dysfunction and mortality in the high Lp-PLA2 group were higher than those in the low Lp-PLA2 group (P<0.05). Seven (15.2%) patients died during 3 months of follow-up. The 3-month survival rate of patients with an increase of Lp-PLA2 was significantly lower than that of the patients with normal Lp-PLA2 (P<0.01), which was an independent predictor of adverse outcomes at 3 months of onset (P<0.01).ConclusionLp-PLA2 may be a predictor of disease progression in the patients with acute type A aortic dissection, and the patients with significantly elevated Lp-PLA2 have a higher 3-month mortality than the patients with normal Lp-PLA2.
Objective To evaluate the relationship of systemic immune inflammatory index (SII) with the clinical features and prognosis of osteosarcoma patients. Methods The clinical data of patients with osteosarcoma surgically treated in Fuzhou Second Hospital between January 2012 and December 2017 were retrospectively collected. The preoperative SII value was calculated, which was defined as platelet × neutrophil/lymphocyte count. The best critical value of SII was determined by receiver operating characteristic (ROC) curve analysis, and the relationship between SII and clinical features of patients was analyzed by χ2 test. Kaplan-Meier method and Cox proportional hazard model were used to study the effect of SII on overall survival (OS). The nomogram prediction model was established according to the independent risk factors of patients’ prognosis. Results A total of 108 patients with osteosarcoma were included in this study. Preoperative high SII was significantly correlated with tumor diameter, Enneking stage, local recurrence and metastasis (P<0.05). The median follow-up time was 62 months. The 1-, 3-, 5-year survival rates of the low SII group were significantly higher than those of the high SII group (100.0%, 96.4%, 85.1% vs. 95.4%, 73.7%, 30.7%), and the survival of the two groups were statistically different (P<0.05). Univariate Cox regression analyses showed that tumor diameter, Enneking stage, local recurrence, metastasis and SII were associated with OS (P<0.05). Multiple Cox regression analysis showed that Enneking stage (P=0.031), local recurrence (P=0.035) and SII (P=0.001) were independent risk factors of OS. The nomogram constructed according to the independent risk factors screened by the Cox regression model had good discrimination and consistency (C-index=0.774), and the calibration curve showed that the nomogram had a high consistency with the actual results. In addition, the ROC curve indicated that the nomogram had a good prediction efficiency (area under the curve=0.880). Conclusions The preoperative SII level is expected to become an important prognostic parameter for patients with osteosarcoma. The higher the SII level is, the worse the prognosis of patients will be. The nomogram prediction model built on preoperative SII level, Enneking stage and local recurrence has a good prediction efficiency, and can be used to guide the diagnosis and treatment of clinical osteosarcoma.
Objective To introduce the inflammatory microenvironment and epithelial-mesenchymal transition process of hepatocellular carcinoma, and review the relationship between them. Methods Domestic and international literatures were collected to summary the relationship between epithelial-mesenchymal transition and the inflammatory microenvironment of hepatocellular carcinoma. Result Many inflammatory factors and viral gene encoding proteins in the inflammatory microenvironment play an important role in the process of epithelial-mesenchymal transition in hepatocellular carcinoma. Conclusions The inflammatory microenvironment of hepatocellular carcinoma is an indispensable role in the process of epithelial-mesenchymal transition. The inhibition and treatment of inflammatory microenvironment may play a more active role in the control of tumor invasion and metastasis.
Objective To investigate the clinical value of peripheral serum cell-free DNA/neutrophil extracellular traps (cf-DNA/NETs) level in diagnosis and severity assessment of sepsis patients. Methods Forty patients with sepsis and 40 patients with non-infectious systemic inflammatory response syndrome (nf-SIRS) were enrolled in this study. The cf-DNA/NETs level in serum of all subjects were measured. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic ability of the cf-DNA/NETs, white blood cell count (WBC), procalcitonin (PCT) and interleukin-6 (IL-6). The sepsis patients were stratified into a survival group and a death group according to the prognosis. Sequential organ failure (SOFA) score were recorded in the sepsis patients, and the correlations between SOFA and cf-DNA/NETs, PCT, WBC, IL-6 were analyzed. Results Compared with the nf-SIRS group, cf-DNA/NETs and PCT levels were significantly higher in the sepsis group (both P<0.05). WBC and IL-6 showed no significant differences between the two groups (bothP>0.05). The area under the ROC curve (AUC) of cf-DNA/NETs was 0.884 for diagnosis of sepsis, and it was higher than the AUC of PCT (0.803). The cf-DNA/NETs showed better sensitivity (81.2% and 79.2%) and specificity (81.0% and 82.4%) than PCT. cf-DNA/NETs and PCT were significantly higher in the death group than those in the survival group. Bivariate collection analysis revealed positive correlations between SOFA score and the two biomarkers of cf-DNA/NETs and PCT (r1=0.573, r2=0.518; both P<0.01). Conclusions cf-DNA/NETs and PCT have certain value in early diagnosis of sepsis, and cf-DNA/NETs shows better diagnostic value in distinguishing sepsis from nf-SIRS than PCT. cf-DNA/NETs can be used as a routine monitoring index to help assess disease severity in sepsis.
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.
Objective To determine the relationship between preoperative prognostic inflammatory and nutritional index (PINI) value and short-term prognosis in colorectal cancer. Methods Patients with colorectal cancer verified by pathologically examine were prospectively enrolled from April 2009 to June 2009. Serum alpha-1-acid glycoprotein, C-reactive protein, albumin and prealbumin were examined on day 3 before operation, and the value of preoperative PINI was calculated. The relationships between preoperative PINI and patho-TNM stage, complications, quality of life, and recurrence and metastasis after operation were analyzed. Results Total 38 patients with colorectal cancer underwent radical surgery were enrolled. Preoperative PINI value was 2.17±1.27. Preoperative PINI value was correlated with TMN stage and M stage: PINI value in patients of Ⅳ stage or M1 stage, were significantly higher than those in ones of Ⅰ, Ⅱ and Ⅲ stage （P＜0.001） or M0 stage （P＜0.001）. There was no significant correlation between preoperative PINI value and preoperative complications （Pgt;0.05）. Preoperative PINI value was correlated with postoperative diet, anorexia and overall quality of life: preoperative PINI value in patients with abnormal diet, anorexia or poor quality of life, were significantly higher than those in ones with normal diet (P=0.020), no-anorexia (P=0.020) or moderate (P=0.025) and well (P=0.020) quality of life. Conclusion Preoperative PINI value is an effective index to assess the short-term prognosis of colorectal cancer.
Objectives To explore the expression of macrophage inflammatory protein-1beta (MIP-1β) in patients with none-small cell lung cancer (NSCLC) of different pathological types and its association with cancer clinical stages and metastasis of lymph nodes.Methods MIP-1β mRNA from fresh lung tissue of 38 NSCLC patients was amplified by RT-PCR and half-quantified.Immunohistochemical technique was performed to find out the expression of MIP-1β in paraffin-embedded lung tissue from 66 patients with NSCLC.The area and degree of stain were evaluated to determine the positive rate，which was compared between with or without metastasis of lymph nodes，different pathological types and TNM clinical stages.Results MIP-1β protein was found in cytoplasm of malignant cells of squama cell cancer and adenocarcinoma without significant difference between them，while not found in bronchus-alveolus cell cancer.The MIP-1β mRNA expression in squama cell cancer and adenocarcinoma were significant higher than which in bronchus-alveolus cell cancer without significant difference between each other.The positive rates of MIP-1β in lung cancer of Ⅰ，Ⅱ and Ⅲ stages were 74.2%，29.4% and 85.7% respectively，which of Ⅰ and Ⅲ stages cancer were significant higher than Ⅱ stage without significant difference between each other.The positive rates of MIP-1β in lung cancer with or without metastasis of lymph nodes were 45.8% and 76.3% respectively with significant difference between them.Conclusion MIP-1β is expressed in lung cancer cells and relates to the pathological type，TNM stage and the metastasis of lymph nodes.
Objective To understand the dynamic changes of inflammatory indicators in the peripheral blood of patients with malignant cerebral edema at different time points after acute cerebral infarction, and provide a basis for early prediction and prevention of malignant cerebral edema. Methods Consecutive patients with acute cerebral infarction within 24 h of onset who were admitted to the Department of Neurology, West China Hospital of Sichuan University between January 1st, 2017 to December 31st, 2018 were collected. The basic clinical data of the patients were collected, and the data of inflammatory cells (white blood cell count, absolute neutrophil count, absolute lymphocyte count, and neutrophil to lymphocyte ratio) and acute phase reactants (blood glucose, fibrinogen, albumin, and fibrinogen to albumin ratio) were dynamically collected at admission and 1, 3, and 7 d after admission, respectively. Differences between groups were compared using generalized estimating equations. Results A total of 798 patients with acute cerebral infarction were included, of whom 93 (11.65%) developed malignant cerebral edema. At all time points examined, the white blood cell counts, absolute neutrophil counts, and neutrophil to lymphocyte ratios were higher in the malignant cerebral edema group than those in the non-malignant cerebral edema group (Wald χ2=63.737, P<0.001; Wald χ2=91.848, P<0.001; Wald χ2=75.197, P<0.001); 1 and 3 d after admission, the absolute lymphocyte counts were lower in the malignant cerebral edema group than those in the non-malignant cerebral edema group (Wald χ2=18.580, P<0.001). The blood glucose levels were higher in the malignant cerebral edema group compared with the non-malignant cerebral edema group 1, 3, and 7 d after admission (Wald χ2=16.722, P<0.001); no significant between-group effect was found in the albumin levels (Wald χ2=3.643, P=0.056); the fibrinogen levels were significantly different between groups 3 d after admission (Wald χ2=8.923, P=0.003), and the fibrinogen to albumin ratios differed between the two groups 3 and 7 d after admission (Wald χ2=6.739, P=0.009). Dynamic analysis of multiple time points in the malignant cerebral edema group found that these inflammatory markers mostly reached their extreme values 3 d after admission. Conclusions Compared with the non-malignant cerebral edema group, the inflammatory cell-related indicators (except lymphocytes) and the acute phase inflammatory reactant-related indicators in malignant cerebral edema patients are significantly higher, and the absolute lymphocyte count is significantly lower. Three days after admission to hospital is probably the most significant time point for the change of each inflammatory indicator.
Objective To assess the effect and safety of clinical nutritional supplementation with different patterns for treating systematic inflammatory response syndrome (SIRS). Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1996 to Nov. 2004), EMBASE (1984 to Nov. 2002), Cochrane Controlled Trials Register (Issue 4, 2004), Chinese Cochrane Centre Database (Issue 4, 2004), CBMdisc (1978 to Nov. 2004). We handsearched related published and unpublished data and their references. All RCTs of nutritional interventions for SIRS were included. Data were extracted and evaluated by two reviewers independently with designed extraction form. RevMan 4.2.7 software was used for data analysis. Results Six RCTs involving 353 patients were included. All the results of meta-analysis were listed as the following: ① Mortality: compared with routine nutrition, one study showed that glutamine had a statistical difference with RR 0.67 and 95%CI 0.31 to 1.32. Compared with no treatment, one study showed selenium had a statistical difference with RR 1.19, 95%CI 0.59 to 2.41. ② Compared with routine nutrition, one study showed that glutamine had a statistical difference on reducing the ratio of nasocomial infection of SIRS with RR 0.5, 95%CI 0.27 to 0.91, but had no statistical difference on reducing the ratio of multiple organ dysfunction syndrome with RR 1.53, 95%CI 0.64 to 3.66. ③ Improvement of the critical condition of SIRS: compared with routine nutrition, one study showed that glutamine had a statistical differences with WMD 4.0, 95%CI 2.36 to 5.64; compared with high calorie intake, two studies showed low calorie intake had a statistical difference with WMD 4.9, 95%CI 1.76 to 8.04. ④ Reduction of the complication of hyperglycemia and hypertriglyceridemia: compared with high calorie intake, one study showed low calorie intake had statistical difference with WMD －0.70, 95%CI －1.20 to －0.20 and WMD －1.80, 95% CI －2.42 to －1.16 respectively and all P≤0.01. ⑤ Increasing of the plasma IgG concentration: compared with routine nutrition, two studies showed that glutamine had a statistical difference with WMD 4.20, 95% CI 2.23 to 6.16. ⑥ Increasing of the nitrogen balance, intestinal permeability, the level of plasma concentration of anlbumin, prealbumin and TRF: compared with control interventions, glutamine, low calorie intake, selenium supplementation and fructose-glucose-xylitol mixture showed no statistical difference. Conclusions Glutamine, low calorie intake, selenium supplementation, FGX mixture may decrease the complication of infection or metabolism and be better than the controlled interventions; but there is no benefit on reducing the rate of death result from SIRS compared with controlled interventions. The evidence of most RCTs with poor quality is too weak to draw a conclusion. More high quality trials are required.
ObjectiveTo investigate the association between preoperative systemic immune-inflammation index (SII) and early allograft dysfunction (EAD) in liver transplant recipients. MethodsThe patients underwent liver transplantation who met the inclusion and exclusion criteria in the West China Hospital of Sichuan University from January 2015 to December 2019 were collected. The postoperative EAD was analyzed. The generalized propensity score weighting (GPSW) were used to balance the confounding factors affecting the occurrence of EAD. ResultsA total of 390 patients who met the inclusion and exclusion criteria were enrolled in this study, 93 cases of EAD occurred, the incidence of EAD was 23.8%. The recipient’s model for endstage liver disease score and Child-Pugh grade, the donor’s body mass index, age, and graft weight, and the intraoperative cold ischemia time, liver transplantation time, intraoperative blood loss, total infusion, red blood cell transfusion, autologous blood reinfusion, fresh frozen plasma transfusion, concentrated platelet transfusion, total red blood cell and autologous blood transfusions were balanced by GPSW, then the overall mean correlation coefficient of the 14 covariables and SII decreased from 0.049 to 0.039, and each covariable reached the standard of less than 0.1. The binary logistic regression analysis based on GPSW showed that there was no significant association between SII and EAD (P=0.371). ConclusionFrom preliminary result of this study, it is not found that preoperative SII of liver transplantation patients is related to occurrence of postoperative EAD.
