Objective To investigate the expression of double-stranded DNA (dsDNA), citrulline histone 3 (CitH3), myeloperoxidase-DNA (MPO-DNA), IL-8 and IL-33 in plasma of patients with chronic obstructive pulmonary disease (COPD) and their clinical significance. Methods Forty patients with acute exacerbation COPD (AECOPD) who were hospitalized in The First Affiliated Hospital of Shihezi University School of Medicine from October 2020 to May 2021 were recruited in the AECOPD group, and recruited in the stable COPD group when they entered the stable stage. In the same period, forty healthy individuals were recruited in the control group. General informations including pulmonary function and peripheral blood were collected from each subject. Plasma levels of CitH3, MPO-DNA, interleukin (IL)-8 and IL-33 were measured by enzyme linked immunosorbent assay and plasma levels of dsDNA were measured by PicoGreen fluorescent dye quantitative analysis. Results The levels of dsDNA, CitH3, MPO-DNA, IL-8 and IL-33 in the AECOPD group were higher than those in the stable group and the control group, with statistical significance (P<0.05), and the levels of dsDNA, CitH3, MPO-DNA and IL-33 in the stable group were higher than those in the control group, with statistical significance (P<0.05) . The levels of CitH3, MPO-DNA, IL-33 and IL-8 in the AECOPD group were positively correlated with COPD assessment test (CAT) score. MPO-DNA and IL-8 were positively correlated with CAT score, MPO-DNA was negatively correlated with FEV1%pred, CitH3 was negatively correlated with FEV1/FVC. The levels of IL-8 and dsDNA, CitH3 were positively correlated with the levels of MPO-DNA in the AECOPD group, and positively correlated with the levels of IL-8 and dsDNA in the stable group, but not with CitH3 and MPO-DNA. The levels of IL-33 and IL-8, dsDNA, CitH3, MPO-DNA were positively correlated in the AECOPD group, but not in the stable group. Conclusions The levels of neutrophil extracellular traps (NETs), IL-8 and IL-33 in plasma of COPD patients were increased, and the levels of NETs were correlated with pulmonary function, CAT score, IL-33 and IL-8. NETs may be involved in the development of COPD.
ObjectiveTo study the expression of cytokine-induced neutrophil chemoattractant-1(CINC-1)in rats with transfusion-related acute lung injury(TRALI),explore its possible role in the pathogenesis of TRALI. MethodsSixty Sprague-Dawley rats were randomly divided into a normal control group with sham operation,a positive control group with ALI induced by intravenous infusion of lipopolysaccharide(5 mg/kg),and a TRALI group treated by intraperitoneal injection of LPS 2h before the transfusion of human plasma (1mL),a LPS control group treated by intraperitoneal injection of LPS 2h before the transfusion of normal saline(1mL).The reverse transcription-polymerase chain (RT-PCR)was used to detect CINC-1 mRNA.The level of CINC-1 in lung tissue homogenate was measured by ELISA.Morphological changes of the lung tissue were observed under light microscope.Myeloperoxidase (MPO)in lung homogenate and wet lung weight to dry lung weight ratio (W/D)were observed.The number of cells and the percentage of polymorphonuclear neutrophil (PMN)in Bronchoalveolar lavage fluid (BALF)were also compared. ResultsCompared with the normal control group and the LPS control group,the expression of CINC-1 protein and CINC-1 mRNA were increased significantly in lung of the positive control group and the TRALI group(P<0.05).The number of cells and the percentage of PMN in BALF of the TRALI group [(310.63±76.67)×106/L and (33.57±11.51)%] were significantly higher than those in BALF of the normal control group [(101.36±63.83)×106/L and (9.87±3.56)%](P<0.05).Tissue water content and MPO activity in the TRALI group were significantly higher than those in the normal control group (P<0.05). ConclusionExpression of CINC-1 protein and CINC-1 mRNA are increased in the rat lung with TRALI and PMN infiltration in lung tissue,which suggests CINC-1 participate in the process of the PMN and endothelial cell adhesion and may play an important role in the pathogeneses of TRALI.
ObjectiveTo explore value of preoperative neutrophil-to-lymphocyte ratio (NLR) combined with carbohydrate antigen 19-9 (CA19-9) in evaluating prognosis for patients with pancreatic head carcinoma.MethodsThe clinical data of patients with pancreatic head carcinoma underwent radical pancreaticoduodenectomy in the Lanzhou University Second Hospital from February 2011 to August 2017 were retrospectively analyzed. The preoperative serum albumin (ALB), CA19-9, NLR, carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), N stage, tumor differentiated degree, and other indicators were recorded and the patient’s overall survival was recorded. Linear correlation analysis was used to examine the association of NLR with serum CA19-9. The receiver operating characteristic (ROC) curve was used to calculate the cutoff values of NLR and CA19-9 corresponding to the overall survival rate of 2-year. Kaplan-Meier method was used for survival analysis. Cox proportional hazards regression model was used to evaluate the prognostic value of preoperative CA19-9 and NLR.Results① A total of 121 patients were enrolled in this study. There was no significant correlation between the preoperative serum CA19-9 and NLR (r=0.100 05, P=0.272 9). ② Multivariate analysis showed that higher NLR, higher CA19-9 level, higher N stage, and lower tumor differentiation were the risk factors for overall survival of pancreatic head carcinoma (P<0.05). ③ The cutoff values of CA19-9 and NLR in evaluating the 2-year overall survival rate were 123.3 U/mL and 2.34 respectively by the ROC curve analysis, the area under ROC curve of CA19-9, NLR, and CA19-9 combined with NLR were 0.763, 0.686, and 0.823, respectively. ④ The proportions of patients with CEA≥5 μg/L and ≥N1 stage were higher in the patients with CA19-9≥123.3 U/mL as compared with patients with CA19-9<123.3 U/mL (P<0.05); The proportions of patients with preoperative serum ALB level <35 g/L and CEA≥5 μg/L, ≥N1 stage, and poor differentiation were higher in the patients with NLR≥2.34 as compared with the patients with NLR<2.34 (P<0.05). ⑤ Kaplan-Meier survival analysis showed that patients with CA19-9≥123.3 U/mL and NLR≥2.34 had worse overall survival than those patients with CA19-9<123.3 U/mL and NLR<2.34 (HR=3.599, P<0.01; HR=2.506, P<0.01). The patients with CA19-9≥123.3 U/mL and NLR≥2.34 (n=42), CA19-9≥123.3 U/mL or NLR≥2.34 (n=48), CA19-9<123.3 U/mL and NLR<2.34 (n=31) had better overall survival in turn (overall and between groups, all P<0.01).ConclusionPreoperative serum CA19-9 combined with NLR has an important value in evaluating prognosis for patients with pancreatic head carcinoma.
ObjectiveTo investigate the relation between preoperative peripheral blood neutrophil/albumin (NEU/ALB) or hypersensitive C-reactive protein (hs-CRP)/ALB ratio and seroma after laparoscopic transabdominal preperitoneal (LTAPP) hernia repair. MethodsThe patients diagnosed with inguinal hernia and underwent LTAPP hernia repair admitted to the Heji Hospital Affiliated to Changzhi Medical College from June 2020 to June 2023 were retrospectively collected. The multivariate logistic regression analysis was conducted to identify the risk factors affecting the occurrence of seroma after LTAPP hernia repair. The area under receiver operating characteristic curve (AUC) and 95% confidence interval (95%CI) were used to evaluate the discriminatory value of preoperative peripheral blood NEU/ALB ratio and hs-CRP/ALB ratio for seroma after LTAPP hernia repair. Delong test was used to compare the discriminatory value of these indicators. The test level was α=0.05. ResultsA total of 357 patients who met the inclusion criteria were included in this study, and the seroma occurred in 42 cases (11.8%). The results of multivariate logistic regression analysis showed that the larger the diameter of the hernia sac [OR (95%CI)=4.654 (2.829, 7.657), P<0.001], the more intraoperative bleeding [OR (95%CI)=3.021 (1.498, 6.094), P=0.002], and the higher NEU/ALB ratio [OR (95%CI)=2.585 (1.618, 4.130), P<0.001] or hs-CRP/ALB ratio [OR (95%CI)=1.874 (1.239, 2.834), P=0.003], the higher the probability of seroma after LTAPP hernia repair. The AUC (95%CI) of NEU/ALB or hs-CRP/ALB indicator for predicting seroma after LTAPP hernia repair was 0.750 (0.702, 0.794) and 0.762 (0.715, 0.806), respectively. The optimal cutoff values were 2.970 and 4.001, with sensitivity of 78.6% and 73.8%, and specificity of 60.3% and 65.7%, respectively. The AUC (95%CI) of the NEU/ALB in combination with hs-CRP/ALB in predicting seroma after LTAPP hernia repair was 0.851 (0.810, 0.886), with sensitivity and specificity of 71.4% and 87.0%, respectively. The AUC of the NEU/ALB in combination with hs-CRP/ALB in predicting seroma after LTAPP hernia repair was higher than that of NEU/ALB (Z=2.864, P=0.004) or hs-CRP/ALB alone (Z=2.956, P=0.003). ConclusionFrom the data analysis results of this study, the occurrence rate of seroma after LTAPP hernia repair is not low, and the occurrence of seroma should be paid close attention to patients with larger hernia sac diameter, more intraoperative bleeding, and higher NEU/ALB or hs-CRP/ALB ratio.
Objective To explore clinical features and risk factors of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) patients with pulmonary involvement. Methods A retrospectively study of clinical data of 113 AAV patients with pulmonary involvement was conducted in the First Affiliated Hospital of Soochow University from January 2015 to December 2020. The differences in general characteristics, treatment and prognosis of different types of AAV with pulmonary involvement were compared. In addition, the clinical characteristics and survival status between the pulmonary involvement group and the non-pulmonary involvement group (n=69) were analyzed. Multivariate logistic regression model was used to analyze the risk factors. Results A total of 113 patients (57 males and 56 females) of AAV with pulmonary involvement were enrolled, including 86 cases of microscopic polyangiitis (MPA), 21 cases of granulomatosis polyangiitis (GPA), 6 cases of eosinophilia granulomatosis (EGPA). The average age was (67±11) years old. There was no significant difference in the age and gender distribution. The clinical manifestations were non-specific. Interstitial lung disease was common imaging feature of MPA, multiple nodules or mass was common in GPA, the incidence of sinusitis in EGPA was significantly higher (P<0.05). Seventy-three patients were complicated with extrapulmonary involvement. The most common organ involved was the kidney, followed by the cardiovascular and nervous system. The most important organs involved in MPA, EGPA and GPA were kidney, heart, and ear, nose, throat respectively. Compared with the non-pulmonary involvement group, the proportions of Birmingham vasculitis activity score (BVAS) ≥15 points, higher antineutrophil cytoplasmic antibody titer and lower complement C3 or C4, pulmonary infection, mechanical ventilation and plasmapheresis in the pulmonary involvement group were significantly higher (P<0.05). Forty patients died during the follow-up. One-year cumulative survival was further calculated using the Kaplan-Meier method, which demonstrated that pulmonary involvement was a risk factor for higher mortality in AAV patients. Compared with the survival group, the proportions of coronary heart disease, multiple organs involvement (n≥3), BVAS≥15 points, serum creatinine≥500 μmol/L, hemoglobin≤90 g/L, C-reactive protein≥10 mg/L, pulmonary infection, requiring mechanical ventilation, continuous renal replacement therapy and plasmapheresis in the death group were significantly higher (P<0.05). Conclusions AAV with pulmonary involvement is more common in the elderly, the morbidity is similar between male and female, and the clinical manifestations are usually non-specific. The chest imaging manifestations are mainly pulmonary interstitial changes, multiple nodules and masses. Multiple organs involvement occurs more often. BVAS≥15 points is independent risk factor for pulmonary involvement in AAV patients. The prognosis of AAV patients with pulmonary involvement is relatively poor. Combined with coronary heart disease, pulmonary infection and CRP≥10 mg/L are independent risk factors of poor prognosis.
Objective To investigate the early diagnostic value of urinary neutrophil gelatinase-associated lipocalin (NGAL) for acute kidney injury (AKI) after acute Stanford type A aortic dissection. Methods From January 2018 to December 2018, the clinical data of 50 patients who underwent open surgery for acute Stanford type A aortic dissection were analyzed in Nanjing First Hospital. Urine specimens were collected before and 2 hours after the aortic dissection surgery. Patients were divided into an AKI group (n=27) and a non-AKI group (n=23) according to the Kidney Disease Improving Global Outcomes criteria. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of urine NGAL. ResultsThe incidence of postoperative AKI was 54.00% (27/50). There was a statistically significant difference between the two groups in serum creatinine concentration at 2 hours after surgery and urinary NGAL concentration before the surgery (P<0.05). The area under ROC curve of preoperative urinary NGAL concentration was 0.626. When cut-off value was 43 ng/mL, the sensitivity was 40.7%, specificity was 95.7%. The area under ROC curve of urinary NGAL concentration at 2 hours after surgery was 0.655, and when the cut-off value was 46.95 ng/mL, the sensitivity was 63.0%, specificity was 78.3%. Conclusion Urine NGAL can predict postoperative AKI in patients with acute Stanford type A aortic dissection, but its value is limited.
ObjectiveTo investigate the application progress of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in various treatment methods of hepatocellular carcinoma(HCC), aiming to fully understand the value of NLR and PLR in various treatments of HCC.MethodRetrieved and reviewed domestic and foreign literatures related to peripheral blood NLR and PLR and HCC in recent years.ResultsThe treatment of HCC mainly included liver resection, liver transplantation, transarterial chemoembolization, radiofrequency ablation, and sorafenib. Peripheral blood NLR and PLR were related to the survival of HCC patients after treatment. High NLR and PLR often indicated poor prognosis for HCC patients.ConclusionNLR and PLR play a certain role in various treatment methods of HCC, and have a certain value in judging tumor prognosis, recurrence, and metastasis.
ObjectiveTo study the clinical significance of prognostic nutritional index (PNI) combined with neutrophil to lymphocyte ratio (NLR) in predicting the occurrence of anastomotic leakage after radical gastrectomy for gastric cancer.MethodsTo retrospectively analyze and collect the clinical data of 517 patients with gastric cancer who were diagnosed at the Third People’s Hospital of Shangqiu City from January 2016 to May 2020, all of the patients received radical gastrectomy. We explored the risk factors that affect the occurrence of postoperative anastomotic leakage, and explored the clinical significance of PNI combined with NLR on the third day after operation in predicting the occurrence of anastomotic leakage.ResultsAmong 517 patients undergoing radical gastrectomy, 61 had anastomotic leakage, and the incidence of anastomotic leakage was 11.8%. The results of multivariate logistic regression analysis showed that patients with preoperative diabetes and intraoperative blood loss ≥400 mL had a higher incidence of anastomotic leakage, and with the increase of NLR value on the 3rd and 5th day after operation, and the decrease of PNI value on the 3rd and 5th day after operation, the incidence of anastomotic leakage increased (P<0.05). The area under the curve of NLR, PNI, and NLR combined with PNI on the 3rd day after operation in predicting the occurrence of anastomotic leakage were 0.849, 0.581, and 0.949, respectively, and the differences were statistically significant (P<0.05), the sensitivity and specificity of NLR combined with PNI were higher than the individual indicator.ConclusionPNI combined with NLR on the 3rd day after operation has important clinical significance in predicting the occurrence of anastomotic leakage after radical gastrectomy for gastric cancer.
