Systemic inflammatory response index is a predictor of prognosis in gastric cancer patients: Retrospective cohort and meta-analysis

BACKGROUND The systemic inflammatory response index(SIRI)has been demonstrated to make a significant difference in assessing the prognosis of patients with different solid neoplasms.However,research is needed to ascertain the accuracy and reliability of applying the SIRI to patients who undergo robotic radical gastric cancer sur-gery.AIM To validate the applicability of the SIRI in assessing the survival of gastric cancer patients and evaluate the clinical contribution of preoperative SIRI levels to predicting long-term tumor outcomes in patients,who received robotic radical gastric cancer surgery.METHODS Initially,an exhaustive retrieval was performed in the PubMed,the Cochrane Library,EMBASE,Web of Science,and Scopus databases to identify relevant studies.Subsequently,a meta-analysis was executed on 6 cohort studies iden-tifying the value of the SIRI in assessing the survival of gastric cancer patients.Additionally,the clinical data of 161 patients undergoing robotic radical gastric cancer surgery were retrospectively analyzed to evaluate their clinicopathological characteristics and relevant laboratory indicators.The association between preoperative SIRI levels and 5-year overall survival(OS)and disease-free survival(DFS)was assessed.RESULTS The findings demonstrated an extensive connection between SIRI values and the outcome of patients with gastric cancer.Preoperative SIRI levels were identified as an independent hazard feature for both OS and DFS among those who received robotic surgery for gastric cancer.SIRI levels in gastric cancer patients were observed to be associated with the presence of comorbidities,T-stage,carcinoembryonic antigen levels,the development of early serious postoperative complications,and the rate of lymph node metastasis.CONCLUSION SIRI values are correlated with adverse in the gastric cancer population and have the potential to be utilized in predicting long-term oncological survival in patients who undergo robotic radical gastric cancer surgery.

Systemic Inflammation Response Index and weight loss as prognostic factors in metastatic pancreatic cancer: A concept study from the PANTHEIA-SEOM trial

BACKGROUND The prognostic value of the Systemic Inflammation Response Index(SIRI)in advanced pancreatic cancer is recognized,but its correlation with patients´nutritional status and outcomes remains unexplored.AIM To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer.METHODS The PANTHEIA-Spanish Society of Medical Oncology(SEOM)study is a multicentric(16 Spanish hospitals),observational,longitudinal,non-interventional initiative,promoted by the SEOM Real World-Evidence work group.This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI.The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers.Patients with pathologically confirmed metastatic pancreatic adenocarcinoma,treated from January 2020 to January 2023,were included.The index was calculated using the product of neutrophil and monocyte counts,divided by lymphocyte counts,obtained within 15 days before initiation chemotherapy.This study evaluated associations between overall survival(OS),SIRI and weight loss.RESULTS A total of 50 patients were included.66%of these patients were male and the median age was 66 years.Metastasis sites:36%liver,12%peritoneal carcinomatosis,10%lung,and 42%multiple locations.Regarding the first line palliative chemotherapy treatments:50%received gemcitabine plus nab-paclitaxel;28%,modified fluorouracil,leucovorin,irinotecan and oxaliplatin,and 16%were administered gemcitabine.42%had a weight loss>5%in the three months(mo)preceding diagnosis.21 patients with a SIRI≥2.3×10^(3)/L exhibited a trend towards a lower median OS compared to those with a SIRI<2.3×10^(3)/L(4 vs 18 mo;P<0.000).Among 21 patients with>5%weight loss before diagnosis,the median OS was 6 mo,in contrast to 19 mo for those who did not experience such weight loss(P=0.003).Patients with a weight loss>5%showed higher SIRI levels.This difference was statistically significant(P<0.000).For patients with a SIRI<2.3×10^(3)/L,those who did not lose>5%of their weight had an OS of 20 mo,compared to 11 mo for those who did(P<0.001).No association was found between carbohydrate antigen 19-9 levels≥1000 U/mL and weight loss.CONCLUSION A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss.An elevated SIRI is suggested as a predictor of survival,emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.

Effects of adjuvant raw rhubarb enema therapy on systemic inflammatory stress response and intestinal mucosal barrier function in patients with severe pancreatitis

Objective: To investigate the effects of adjuvant raw rhubarb enema therapy on systemic inflammatory stress response and intestinal mucosal barrier function in patients with severe pancreatitis. Methods: A total of 78 patients with severe pancreatitis treated in the Second People's Hospital of Neijiang, Sichuan, China between December 2016 and September 2018 were included in the study. The patients were divided into control group (n=39) and raw rhubarb group (n=39) by simple randomization. The control group of patients received conventional treatment of severe pancreatitis with western medicine, while the raw rhubarb group of patients received raw rhubarb enema on the basis of the treatment of control group, and the efficacy was evaluated after continuous treatment for 1 week. The differences in serum levels of inflammatory mediators (high mobility group protein B1, C-reactive protein, prostaglandin E2 and tumor necrosis factor α), stress hormones (cortisol and epinephrine) as well as intestinal mucosal barrier function indicators (D-lactate, endotoxin and diamine oxidase) were compared between the two groups of patients before and after treatment. Results: Before treatment, there was no statistically significant difference in serum levels of inflammatory mediators, stress hormones and intestinal mucosal barrier function indicators between the two groups (P>0.05). After treatment, serum high mobility group protein B1, C-reactive protein, prostaglandin E2 and tumor necrosis factor levels of the observation group were significantly lower than those of the control group;cortisol and epinephrine levels were significantly lower than those of the control group;D-lactate, endotoxin and diamine oxidase levels were significantly lower than those of the control group (P<0.05). Conclusions:Adjuvant raw rhubarb enema therapy on the basis of western medicine can help alleviate the inflammatory stress response and optimize the intestinal mucosal barrier function in patients with severe pancreatitis.

Effects of ulinastatin combined with octreotide therapy on systemic inflammatory response and intestinal mucosal function in patients with severe pancreatitis

Objective: To investigate the effects of ulinastatin combined with octreotide therapy on systemic inflammatory response and intestinal mucosal function in patients with severe pancreatitis. Methods: A total of 82 patients with severe pancreatitis who were treated in the First People's Hospital of Liangshan Prefecture between March 2015 and August 2017 were reviewed and divided into control group (n=43) and ulinastatin group (n=39), control group received conventional + octreotide therapy, ulinastatin group received conventional +octreotide + ulinastatin therapy, and both groups were treated for 1 week. The differences in systemic inflammatory response and intestinal mucosal function were compared between the two groups before and after treatment. Results: Before treatment, the differences in serum levels of inflammatory mediators and intestinal mucosal function indexes were not statistically significant between the two groups. After 1 week of treatment, serum levels of inflammatory mediators IL-1β, IL-8, HMGB-1 and MCP-1 as well as intestinal mucosal function indexes ET, DAO and D-lactose of ulinastatin group were lower than those of control group. Conclusion: Ulinastatin combined with octreotide therapy on the basis of conventional treatment can further inhibit the systemic inflammatory response and actively protect the intestinal mucosal function in patients with severe pancreatitis.

Prognostic value of preoperative prognostic nutritional index and its associations with systemic inflammatory response markers in patients with stage Ⅲ colon cancer

Background: The prognostic nutritional index(PNI) has been widely applied for predicting survival outcomes of patients with various malignant tumors. Although a low PNI predicts poor prognosis in patients with colorectal cancer after tumor resection, the prognostic value remains unknown in patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy. This study aimed to investigate the prognostic value of PNI in patients with stage III colon cancer.Methods: Medical records of 274 consecutive patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy with oxaliplatin and capecitabine between December 2007 and December2013 were reviewed. The optimal PNI cutoff value was determined using receiver operating characteristic(ROC) curve analysis. The associations of PNI with systemic inflammatory response markers, including lymphocyte-to-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), and C-reactive protein(CRP)level, and clinicopathologic characteristics were assessed using the Chi square or Fisher's exact test. Correlation analysis was performed using Spearman's correlation coefficient. Disease-free survival(DFS) and overall survival(OS)stratified by PNI were analyzed using Kaplan-Meier method and log-rank test, and prognostic factors were identified by Cox regression analyses.Results: The preoperative PNI was positively correlated with LMR(r= 0.483, P < 0.001) and negatively correlated with NLR(r =-0.441, P < 0.001), PLR(r =-0.607, P < 0.001), and CRP level(r =-0.333, P < 0.001). A low PNI(≤49.22)was significantly associated with short OS and DFS in patients with stage ⅢC colon cancer but not in patients with stage ⅢA/ⅢB colon cancer.In addition, patients with a low PNI achieved a longer OS and DFS after being treated with6-8 cycles of adjuvant chemotherapy than did those with < 6 cycles. Multivariate analyses revealed that PNI was independently associated with DFS(hazard ratios 2.001; 95% confidence interval 1.157-3.462; P = 0.013).Conclusion: The present study identified preoperative PNI as a valuable predictor for survival outcomes in patients with stage Ⅲ colon cancer receiving curative tumor resection followed by adjuvant chemotherapy.

Periplaneta americana extract used in patients with systemic inflammatory response syndrome

BACKGROUND:Periplaneta americana extract is recognized to have a positive effect on gastrointestinal mucosa.This study aimed to investigate the effects of periplaneta americana extract on immune function,nutrition status and gastrointestinal complications of early enteral nutrition patients with systemic inflammatory response syndrome(SIRS).METHODS:Patients with SIRS were randomly divided into two groups:treatment and control groups.All patients in the two groups received conventional therapy including enteral nutrition,but periplaneta americana extract,an additional Chinese medicine,was given to the patients in the treatment group.At the beginning of treatment(0 day)and 1,3,and 7 days after treatment,the levels of immunoglobulin(Ig A),total lymphocyte count(TLC),total protein(TP)and prealbumin(PA)were respectively tested in patients'venous blood.The incidences of bloating,diarrhea,aspiration pneumonia and high blood sugar at 7 days after treatment were recorded.The mortality of the patients in 28 days was recorded.RESULTS:At 3 and 7 days after treatment,the levels of Ig A and TLC in the treatment group were higher than those in the control group(P<0.05).At 7 days after treatment,the levels of TP and PA in the treatment group were higher than those in the control group(P<0.05).The incidences of bloating and diarrhea in the treatment group were lower than those in the control group,the differences were significant(P<0.05).The mortality of treatment group was lower than that of the control group(P>0.05).CONCLUSION:Periplaneta americana extract could reduce gastrointestinal complications and improve immune function and nutritional status in patients with systemic inflammatory response syndrome.

Expression and Significance of Toll-like Receptor 2,4 of Peripheral Blood Mononuclear Cells in Acute Abdomen Patients Associated with Systemic Inflammatory Response Syndrome

The changes of Toll-like receptor （TLR） 2, 4 of peripheral blood mononuclear cells （PBMCs） in the acute abdomen patients associated with systemic inflammatory response syndrome （SIRS） and their potential significance were explored. A clinical study was performed on 103 acute abdomen patients in whom 65 were associated with SIRS. Forty healthy individuals served as normal controls. The mRNA expression of TLR2, 4 was detected by RT-PCR, and the expression of TNF-α and IL-6 by ELISA. The level of plasma endotoxin, hospital stay and mortality were measured. It was found that the endotoxin level was increased to varying degrees in all the acute abdomen patients, and the endotoxin level was and hospital stay longer in SIRS group than in non-SIRS group （P〈0.01）. TLR2 mRNA, TLR4 mRNA, IL-6 and TNF-ct could be detected with low value in normal controls, but they were up-regulated markedly on the 1 st day after admission. Then TLR4 mRNA, IL-6 and TNF-α were decreased gradually, but TLR2 mRNA maintained at a high level till the 5th day. These indexes above in SIRS group were higher than those in non-SIRS group （P〈0.01）. The results of correlation analysis revealed the expression of TLR2, 4 mRNA was positively correlated with the levels of TNF-α and IL-6, and the hospital stay, The results of Logistic regression demonstrated that overexpression of TLR2, 4 mRNA might result in higher risk of multiple organ dysfunction syndrome （MODS）. It was concluded that in the acute abdomen patients associated with SIRS, the expression of TLR2, 4 in PBMCs was increased markedly, suggesting that TLR might play an important role in the pathogenesis of acute abdomen associated with SIRS.

Effects of internal iliac artery embolization on systemic inflammatory response syndrome in dogs with simulatedpelvic-fracture combined with massive bleeding

Background: Pelvic fracture combined with massive bleeding(PFCMB) is a complex issue in clinical practice. Currently, the use of angiography and embolization for the treatment of PFCMB obtains good results. The aim of this study is to observe the effects of early internal iliac artery embolization on the systemic inflammatory response syndrome(SIRS) in dogs with simulated-pelvic-fracture combined with massive bleeding.Methods: Twenty adult dogs were randomly divided into an embolization group(EG) and a control group(CG). For the two groups, heart rate, respiratory rate and body temperature and other physiological variables were measured, and IL-6, TNF-α and arterial blood gas levels were monitored. These variables were assayed every 30 min until death in the CG, while dogs in the EG underwent arterial angiography after 60 min of modeling. The internal iliac artery was embolized on the injured side.Results: The average time to SIRS in the CG was 3.56 h, occurring at a rate of 90%(9/10) within 24 h, with a mortality rate of 50%(5/10); the average time to SIRS for the EG was 5.33 h, occurring at a rate of 30%(3/10) within 24 h, with a mortality rate of 10%(1/10). When SIRS occurred in the EG, the mean plasma IL-6 level was 52.66±7.38pg/ml and the TNF-ps, tα level was 11.45±2.72ng/ml, showing a significant difference with those of the CG(P<0.05). In the two grouhe respiratory rate and leukocyte levels were higher at each monitored time after modeling than those before modeling; the mean arterial pressure, levels of hemoglobin and oxygen partial pressure were significantly lower at each time point after modeling than those before modeling except for the mean arterial pressure at 0h in EG; the platelet levels at 4 and 8h were higher than those before modeling; and the differences were statistically significant(P<0.05). In the EG, the mean arterial pressure, heart rate, respiratory rate and hemoglobin levels at 2, 4 and 8h were lower than those at 0h; the levels of leukocytes, platelets and carbon dioxide partial pressure at 4 and 8h after modeling were higher than those at 0h, and the differences were statistically significant(P<0.05, P<0.01); in the CG after modeling, the mean arterial pressure, levels of hemoglobin and carbon dioxide partial pressure at 2, 4 and 8h were lower than those at 0h; the levels of heart rate and leukocytes were higher than those before modeling; the respiratory rate and platelet levels at 4 and 8h were higher than those at 0h; and the differences were statistically significant(P<0.05). The levels of the mean arterial pressure and hemoglobin at 4 and 8h and the p H values at 8h after modeling in the EG were significantly higher than those in the CG, while the heart rate and respiratory rate at 4 and 8h were significantly lower than those in the CG. The p H values at 8h after modeling were significantly lower than those of the other monitored times in the CG(P<0.05, P<0.01). The two groups had elevated levels of alkaline phosphatase after injury induction.Conclusion: Through the use of an on-spot interventional treatment cabin, early internal iliac artery embolization can control bleeding associated with pelvic fractures, delay the occurrence of SIRS, and improve the success rate of the treatment of pelvic fracture combined with bleeding.

Urokinase-type plasminogen activator receptor as a predictor of poor outcome in patients with systemic inflammatory response syndrome

BACKGROUND:Urokinase-type plasminogen activator(uPA) and urokinase-type plasminogen activator receptor(uPAR) are known as important factors,which mediate a variety of functions in terms of vascular homeostasis,inflammation and tissue repair.However,their role in systemic inflammatory response syndrome(SIRS) has been less well studied.This study aimed to test the hypothesis that the abnormalities of fibrinolysis and degradation of extracellular matrix mediated by uPA and uPAR are directly related to the patients with SIRS.We therefore analyzed their role and clinicopathological significance in patients with SIRS.METHODS:A case-control study was conducted with 85 patients who were divided into two groups according to the diagnostic criteria of SIRS:SIRS group(n=50) and non-SIRS group(/7=35).The SIRS group was divided into MODS group(n=26) and non-MODS group(n=24) by their severity,and survival group(n=35) and non-survival group(n=15) by their prognosis.Another 30 healthy adults served as normal controls.uPA and uPAR in plasma were detected by commercial enzyme-linked immunosorbent assay(ELISA) kits.RESULTS:The plasma level of uPA was lower in the SIRS group than in the non-SIRS group and controls(P<0.001 and P<0.001).It was lower in sepsis patients and the MODS group than in the non-sepsis patients and the non-MODS patients(all P<0.05).However,there was no difference in uPA level between survivors and non-survivors(P>0.05).The plasma level of uPAR increased in the SIRS group compared with the non-SIRS group and controls(P<0.001 and P<0.001).There was a significant elevation of uPAR in sepsis patients,MODS patients and non-survivors as compared with non-sepsis patients,non-MODS patients and survivors respectively(all P<0.05).Plasma uPAR levels were positively correlated with APACHE Ⅱ score(r=0.575,P<0.001) and SOFA score(r=0.349,P=0.013).AUCs for the prediction of SIRS mortality were 0.67 and 0.51,respectively,for uPA and uPAR.CONCLUSION:uPAR could be a predictor of poor outcome in patients with SIRS.

Activated systemic inflammatory response at diagnosis reduces lymph node count in colonic carcinoma

AIM: To investigate a link between lymph node yield and systemic inflammatory response in colon cancer. METHODS: A prospectively maintained database was interrogated. All patients undergoing curative colonic resection were included. Neutrophil lymphocyte ratio(NLR) and albumin were used as markers of SIR. In keeping with previously studies, NLR ≥ 4, albumin < 35 was used as cut off points for SIR. Statistical analysis was performed using 2 sample t-test and χ~2 tests where appropriate.RESULTS: Three hundred and two patients were included for analysis. One hundred and ninety-five patients had NLR < 4 and 107 had NLR ≥ 4. There was no difference in age or sex between groups. Patients with NLR of ≥ 4 had lower mean lymph node yields than patients with NLR < 4 [17.6 ± 7.1 vs 19.2 ± 7.9(P = 0.036)]. More patients with an elevated NLR had node positive disease and an increased lymph node ratio(≥ 0.25, P = 0.044). CONCLUSION: Prognosis in colon cancer is intimately linked to the patient’s immune response. Assuming standardised surgical technique and sub specialty pathology, lymph node count is reduced when systemic inflammatory response is activated.

Severity of Symptoms of Systemic Inflammatory Response Syndrome and Congestive Heart Failure Caused by Chronic Aortic Stenosis and Its Pharmacological Correction

Systemic inflammatory response syndrome (SIRS) is one of the key accompanied states that worsens severity of congestive heart failure (CHF) and leads refractory CHF to conventional therapy. We investigated whether the cessation of the symptoms and signs of SIRS prevents the progression of the CHF caused by chronic aortic stenosis in rabbits. 8 weeks after induced CHF by left descending coronary artery stenosis, all animals were randomly assigned into 3 groups: control (CG)—without therapy (infusion of 0.9% NaCl);main I— receive mg/kg of Adenocin&reg;dissolved in water for injection i.v., once daily and main II—animals receive 0.25 mg/kg enalapril i.m, furosemide 1.0 mg/kg i.v. (bolus) and pimobendan 0.1 mg/kg i.v. once daily. All animals were euthanized after 14 days of the beginning of treatment. Long-term aortic stenosis leads to a simultaneously developing of CHF, diagnosed by developing cardiac hypertrophy, increased level of BNP and myocardial oedema and SIRS, confirmed by increasing markers and symptoms of endotoxemia, tissue dysoxia and decreasing reserve ability of intrinsic defense systems. Restoration of myocardium redox-potential and level of NAD under treatment with Adenocin&reg;leads unlike combined treatment with enalapril, furosemide and pimobendan to restoration, the regulatory pathways of TNF-α synthesis, cessation of the hypoxic/ischemic, lysosomal dysfunction and free radical-induced damage in myocardium and symptoms of CHF. Potential important link between cellular metabolism (hypoxia/ischemia), endotoxemia and disturbances in intrinsic defense system is the level of redox-potentail, NAD/NADH in myocardium. Influence of oxidized form of NAD-containing positive inotropic drug Adenocin&reg;leads to the decreasing symptoms of CHF and beneficial action occurs on all the key links of SIRS.

Shock index of patients with sepsis after continuous blood purification treatment and its relationship with systemic inflammatory response syndrome and immune response

Objective:To study the shock index of patients with sepsis after continuous blood purification (CBP) treatment and its relationship with systemic inflammatory response syndrome and immune response.Methods:A total of 88 patients with sepsis who underwent continuous blood purification treatment in our hospital between June 2012 and May 2016 were chosen as research subjects, shock index (SI) was compared before and after the treatment, and according to the level of SI after treatment, all patients were divided into shock group (n=27) with SI>0.5 points and no shock group (n=61) with SI≤0.5 points. Serum contents of inflammatory mediators, Th1/Th2 cellular immunity indexes, immunoglobulin and complement were compared between two groups of patients after treatment.Results: The level of SI in patients with sepsis was significantly lower than that before treatment. Serum contents of inflammatory mediators PCT, CRP and HMGB1 in no shock group were lower than those in shock group, contents of Th1 cytokines IL-2 and IFN-γ were higher than those in shock group, contents of Th2 cytokines IL-10 and IL-13 were lower than those in shock group, and contents of IgG, IgM, IgA, C3 and C4 were higher than those in shock group.Conclusion: The level of SI decreases in the patients with sepsis after CBP treatment, and SI level is directly correlated with the systemic inflammatory response syndrome and immune response levels.

Integrated systemic inflammatory response syndrome epidemic model in scale-free networks

Based on the scale-free network, an integrated systemic inflammatory response syndrome model with artificial immunity, a feedback mechanism, crowd density and the moving activities of an individual can be built. The effects of these factors on the spreading process are investigated through the model. The research results show that the artificial immunity can reduce the stable infection ratio and enhance the spreading threshold of the system. The feedback mechanism can only reduce the stable infection ratio of system, but cannot affect the spreading threshold of the system. The bigger the crowd density is, the higher the infection ratio of the system is and the smaller the spreading threshold is. In addition, the simulations show that the individual movement can enhance the stable infection ratio of the system only under the condition that the spreading rate is high, however, individual movement will reduce the stable infection ratio of the system.

The expression of toll-like receptor 2, 4 of livers in mice with systemic inflammatory response syndrome

BACKGROUND: The complicated pathogenesis of systemic inflammatory response syndrome (SIRS) is a hot topic in critical care medicine. In this study we explored the expression of toll-like receptor (TLR) 2, 4 of livers in SIRS mice and evaluated the role of TLR2, 4 in the pathogenesis of SIRS. METHODS: Forty BABL/C mice were randomly divided into 2 groups: control (n=20) and SIRS (n=20). SIRS model was induced by severe acute pancreatitis. Blood routine, blood amylase, glutamic pyruvic transaminase and temperature were measured. Histological changes of pancreases and livers were observed microscopically. The mRNA expressions of TLR2, 4 were detected by real-time polymerase chain reaction (PCR). The protein expressions of TLR2, 4 were examined by Western blot. RESULTS: Marked edema, inflammatory cell infiltration, hemorrhage, and necrosis were observed in the pancreases and livers of SIRS mice. The concentrations of amylase and glutamic pyruvic transaminase were increased significantly. Body temperature and white blood cell count were decreased. The mRNA and protein expressions of TLR2, 4 increased markedly in SIRS mice. Significant difference was observed between SIRS and control mice (P【0.01). CONCLUSION: The expressions of TLR2, 4 of livers were increased markedly in SIRS mice, indicating that TLR might play an important role in the pathogenesis of SIRS.

Clinical application of procalcitonin combined with interleukin-6 in the diagnosis of systemic inflammatory response syndrome

Objective:To investigate the clinical application value of procalcitonin(PCT) combined with interleukin-6(IL-6) in the diagnosis of systemic inflammatory response syndrome(SIRS). Methods: 115 cases of SIRS patients were divided into sepsis group(n=46) and non-infectious SIRS group(n=69). The serum levels of PCT, IL-6 were detected within 24 h of admission in two groups. White blood cell count (WBC), neutrophil counts (N), neutrophil percentage (N %), C - reactive protein (CRP) and acute physiology and chronic health evaluation (APACHEⅡ score), sequential organ failure score (SOFA score) were recorded.Results:APACHEⅡscore, SOFA score, hospital mortality had statistical differences between sepsis group and noninfectious SIRS group (P < 0.05). The serum levels of CRP、PCT、IL-6 and N% in sepsis group were higher than those in noninfectious SIRS group(P<0.05). PCT and IL - 6 were positively correlated with APACHEⅡ scores (r = 0.580, 0.463), N, N %, PCT, IL - 6 were positively correlated with SOFA scores (r = 0.371, 0.393, 0.371, 0.393), PCT was positively related with hospital mortality (r = 0.349). ROC curve analysis showed that compared with CRP, N, N% and other inflammatory markers, the AUC of PCT, il-6 and infection score was larger, and the value of diagnosis was higher.Conclusion:The combined detection of PCT and IL-6 is more effective than single detection in prognosis of sepsis.

Effect of ulinastatin combined with antibiotics on systemic inflammatory response and stress hormone secretion in patients with acute severe pneumonia

Objective:To study the effect of ulinastatin combined with antibiotics on systemic inflammatory response and stress hormone secretion in patients with acute severe pneumonia. Methods: A total of 78 patients with acute severe pneumonia in our hospital between December 2014 and January 2017 were randomly divided into routine group and ulinastatin group, each with 39 cases. Routine group were treated with conventional antibiotics, ulinastatin group were treated with ulinastatin and antibiotics, and the treatments lasted for 2 weeks. The differences of serum acute phase proteins, inflammatory factors and stress hormones were compared between the two groups before and after treatment.Results: Before treatment, there were no significant differences in serum contents of acute phase proteins, inflammatory factors or stress hormones between the two groups. After 2 weeks of treatment, serum acute phase protein prealbumin (PA) content in ulinastatin group was higher than that in routine group whereas C-reactive protein (CRP) content was lower than that in routine group;serum inflammatory cytokines interleukin-1β (IL-1β), interleukin-2 (IL-2) and interleukin-6 (IL-6) contents in ulinastatin group were lower than those in routine group;serum stress hormones NE, Cor and AngII contents in ulinastatin group were lower than those in routine group. Conclusion:Ulinastatin combined with antibiotics for acute severe pneumonia can inhibit the systemic inflammatory response and stress response.

Serum RAAS molecules and their relationship with the systemic inflammatory response and target organ function in patients with severe acute pancreatitis

Objective:To explore the relationship of renin-angiotensin-aldosterone system (RAAS) activity with the systemic inflammatory response and target organ function in patients with severe acute pancreatitis.Methods: A total of 78 patients with severe acute pancreatitis who were treated in our hospital between August 2012 and March 2016 were selected as the observation group, and 50 healthy people who underwent physical examination in our hospital during the same period were selected as the normal control group. The differences in the contents of RAAS indexes, inflammation indexes as well as liver and kidney function indexes were compared between the two groups, and Pearson test was used to evaluate the correlation between RAAS activity and illness in patients with severe acute pancreatitis.

Conclusion: glutamine enteral nutrition + low molecular weight heparin can effectively relieve systemic inflammatory response and oxidative stress response, and reduce the myocardial injury in patients with severe pneumonia.

Correlation of serum CRP and PCT levels with systemic inflammatory response in patients with acute exacerbation of COPD

Objective:To investigate the correlation of serum C-reactive protein (CRP) and procalcitonin (PCT) levels with systemic inflammatory response in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:68 patients with acute exacerbation of COPD treated in our hospital between August 2012 and February 2016 were collected as observation group and 50 normal subjects receiving physical examination in our hospital during the same period were selected as normal control group. Radioimmunoassay was used to determine serum CRP and PCT levels;the observation group was further grouped according to the median of CRP and PCT levels, and serum levels of pro-inflammatory factors, anti-inflammatory factors and stress hormones of high level group and low level group were detected.Results:Serum CRP and PCT levels of observation group were significantly higher than those of normal control group (P<0.05);serum pro-inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6) and interleukin-8 (IL-8) levels of high CRP and PCT level groups within observation group were higher than those of low CRP and PCT level groups (P<0.05), anti-inflammatory factors interleukin-4 (IL-4) and interleukin-13 (IL-13) levels were lower than those of low CRP and PCT groups (P<0.05), and stress hormones angiotensin II (Ang II), aldosterone (ALD) and cortisol (Cor) levels were higher than those of low CRP and PCT level groups (P<0.05).Conclusions:Serum CRP and PCT levels in patients with acute exacerbation of COPD are positively correlated with the inflammatory response extent in the body, and can be used as the auxiliary means for early disease diagnosis, treatment effect evaluation and prognosis judgment.
