ABSTRACT
SUMMARY OBJECTIVE: Clinical diagnosis of acute appendicitis is often difficult and involves a synthesis of clinical, laboratory, and radiological findings. The aim of this study was to investigate whether the systemic immune inflammation index can be used as an effective parameter in the diagnosis of acute appendicitis and its reliability in the differentiation of complicated vs. non-complicated appendicitis. METHODS: The study was conducted retrospectively with patients admitted to the emergency department with abdominal pain and diagnosed with acute appendicitis. In total, 150 patients and 150 control cases were included in the study. Demographic data, medical history, white blood cell count, platelet count, neutrophil count, systemic immune inflammation index values, Alvarado score, adult appendicitis score, and pathology result of appendectomy material were retrieved from the hospital automation system and recorded in the data form. RESULTS: Neutrophil-lymphocyte ratio and systemic immune inflammation index were significantly higher, and platelet-neutrophil ratio and lymphocyte-neutrophil ratio were significantly lower in the patient group compared to the control group (p<0.001). Receiver operating characteristic analysis revealed that the sensitivity and specificity of systemic immune inflammation index with a cutoff value of 840.13 was 82 and 66.7%, respectively, for the diagnosis of acute appendicitis. Correlation analysis revealed that systemic immune inflammation index, Alvarado score, and adult appendicitis score were positively correlated, and this correlation was statistically significant. CONCLUSION: Systemic immune inflammation index may be used to promote the diagnosis of acute appendicitis and may reduce the need for radiation exposure and diagnostic imaging tests such as contrast-enhanced abdominal computed tomography. It can also be used to differentiate between complicated and non-complicated acute appendicitis cases.
ABSTRACT
Objective:To investigate the prognostic value of systemic immune-inflammation index (SII) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:The clinical data, including age, gender, complications, laboratory examination results post-admission, SII, model for end-stage liver disease (MELD) score, MELD-Na score, Child-Turcotte Pugh (CTP) score of HBV-ACLF patients treated in Huashan Hospital, Fudan University from January 2016 to August 2021 were retrospectively analyzed. The patients were divided into survival group and death group according to the outcome at 90 days of follow-up.Paired sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis.Pearson correlation was used to analyze the correlation between SII and the prognosis prediction model of HBV-ACLF. The area under the curve (AUC) was used to analyze the clinical efficacies of SII, MELD score, MELD-Na score and CTP score in predicting the prognosis of HBV-ACLF patients, and the optimal cut-off value of SII for predicting the prognosis of HBV-ACLF was calculated. Kaplan-Meier method was used for survival analysis. Results:A total of 140 patients with HBV-ACLF were included. There were 88 patients in the survival group, including 65 males and 23 females, with the age of (47.69±11.96) years. There were 52 cases in the death group, including 40 males and 12 females, with the age of (52.73±12.22) years. The age, aspartate aminotransferase, total bilirubin, serum creatinine, international normalized ratio, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, SII, MELD score, MELD-Na score, CTP score and the incidence of infection in the death group were all significantly higher than those in the survival group, and albumin, lymphocyte count, platelet count, prognostic nutritional index in the death group were all significantly lower than those in the survival group, and the differences were all statistically significant ( t=-2.39, Z=-2.84, t=-4.81, Z=-2.15, Z=-4.91, Z=-3.47, Z=-3.36, Z=-3.83, Z=-4.69, Z=-4.56, Z=-6.31, χ2=24.96, t=3.06, t=3.03, Z=-7.57 and t=4.12, respectively, all P<0.05). Pearson correlation analysis showed that SII was positively correlated with CTP score ( r=0.272 7, P=0.001), MELD score ( r=0.365 8, P<0.001) and MELD-Na score ( r=0.381 1, P<0.001). The AUC of SII was the largest of 0.80, and 0.76 for MELD score, 0.74 for MELD-Na score and 0.73 for CTP score. The optimal cut-off value of SII was 447.49. Kaplan-Meier analysis showed that the 90 days survival rate of patients with SII≥447.49(38.60%(22/57)) was lower than that of SII<447.49 group (79.52%(66/83)), and the difference between the two groups was significant ( χ2=23.80, P<0.001). Conclusions:SII can be used to assess the severity and prognosis of HBV-ACLF patients. SII ≥447.49 indicates poor prognosis.
ABSTRACT
Objective:To observe the expression levels of Toll-like receptor 4 (TLR4) signaling pathway-related proteins and their phosphorylation in the liver tissues of rats with inorganic arsenic poisoning, and to explore the role of TLR4-mediated inflammatory signaling pathway in arsenic-induced liver fibrosis injury.Methods:Eighteen healthy weanling SD rats were divided into 3 groups according to their body weight (80 - 100 g) using a random number table (6 rats in each group, half males and half females). The control group was given 10 ml/kg of normal saline by gavage. The sodium arsenite (NaAsO 2) exposure group was given 10 mg/kg of NaAsO 2 by gavage. The TAK-242 intervention group was given 10 mg/kg of NaAsO 2 by gavage, and 0.5 mg/kg of TAK-242 was also administered intraperitoneally to inhibit TLR4 after 12 weeks. All rats were administered 6 days a week for 36 weeks. At the end of the treatment, the liver tissues and serum of the rats in each group were collected. HE and Masson staining were used to observe the pathological and fibrotic changes of the liver tissues. Automatic biochemical analyzer was used to detect serum liver function indexes of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). Western blot was used to detect the expression changes of rat liver fibrosis protein α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1), Vimentin and TLR4 signaling pathway-related proteins TLR4, nuclear factor κB (NF-κB)-p65 subunit (p65), NF-κB-p50 subunit (p50) and their phosphorylation p-p65 and p-p50 expression levels. Enzyme-linked immunosorbent assay (ELISA) was used to detect the secretion levels of inflammatory related factors interleukin (IL)-6, tumor necrosis factor-α (TNF-α) and IL-10. Results:HE and Masson staining results showed that compared with the control group, the NaAsO 2 exposure group showed significant inflammatory cell infiltration, hepatocyte necrosis and collagen fibrous deposition, while the TAK-242 intervention group showed improvement of the inflammatory cell infiltration and reduction of collagen fibrous deposition compared with the NaAsO 2 exposure group. The results of serum liver function indexes showed that ALT, AST and ALP in NaAsO 2 exposure group were increased compared with the control group, but the TAK-242 intervention group was significantly decreased compared with the NaAsO 2 exposure group ( P < 0.05). Western bolt results showed that in NaAsO 2 exposure group, the expression levels of fibrosis protein α-SMA, TGF-β1 and Vimentin (1.04 ± 0.19, 0.92 ± 0.14, 1.20 ± 0.21) and TLR4 signaling pathway-related proteins and their phosphorylation TLR4, p50, p-p50 and p-p65 (1.16 ± 0.21, 0.95 ± 0.16, 1.24 ± 0.23, 1.56 ± 0.25) were higher than the control group (0.44 ± 0.08, 0.42 ± 0.08, 0.72 ± 0.07, 0.69 ± 0.15, 0.71 ± 0.11, 0.46 ± 0.07, 0.54 ± 0.11, P < 0.05), and the TAK-242 intervention group (0.60 ± 0.13, 0.59 ± 0.16, 0.49 ± 0.11, 0.47 ± 0.08, 0.86 ± 0.09, 0.79 ± 0.14, 1.02 ± 0.17) were lower than the NaAsO 2 exposure group ( P < 0.05). There was no significant difference in the expression level of TLR4 signal pathway-related protein p65 among the three groups ( F = 14.29, P = 0.053). ELISA results showed that the secretion levels of IL-6 and TNF-α [(98.89 ± 4.58), (83.25 ± 4.57) ng/g] in rats liver tissues of the NaAsO 2 exposure group were higher than the control group [(27.30 ± 3.92), (27.77 ± 1.83) ng/g, P < 0.05], while the secretion level of IL-10 [(36.88 ± 3.86) ng/g] was lower than the control group [(77.96 ± 7.87) ng/g, P < 0.05]. In TAK-242 intervention group, IL-6 and TNF-α secretion levels [(44.32 ± 3.60), (36.51 ± 2.93) ng/g] were lower and IL-10 secretion level [(60.40 ± 4.94) ng/g] was higher compared with the NaAsO 2 exposure group ( P < 0.05). Conclusion:TLR4-mediated inflammatory signaling pathway-related proteins and their phosphorylation are highly expressed in the liver tissues of rats with inorganic arsenic poisoning, and inhibition of TLR4 signaling pathway could significantly reduce the degree of liver fibrosis injury caused by inorganic arsenic in rats.

Objective:To investigate the predictive value of systematic immune-inflammation index(SII) in severity and prognosis of the patients with acute pulmonary embolism(APE).Methods:By retrospective research methods, the clinical data of 120 APE patients from June 2020 to January 2022 in Hubei University of Medicine Affiliated Dongfeng General Hospital were analyzed. The pulmonary embolism-related deaths within 6 months was the end point events. The influence factors were explored by multivariate Logistic regression analysis, the predictive value of pulmonary embolism severity index (PESI) and SII on the end point events of patients were assessed by receiver operating characteristic(ROC) curve.Results:According to the pulmonary embolism-related deaths within 6 months as the end point events they were divided into the survival group (96 cases) and the death group (24 cases). The age, systolic blood pressure, heart rate, respiratory rate, incidence of congestive heart failure, level of B-type natriuretic peptide, PESI score, and SII in the death group were higher than those in the survival group: (66.00 ± 8.85) years vs. (61.21 ± 5.99) years, (129.83 ± 14.76) mmHg (1 mmHg = 0.133 kPa) vs. (122.77 ± 10.21) mmHg, (102.04 ± 9.43) beats/min vs. (92.54 ± 11.34) beats/min, (20.83 ± 2.37) beats/min vs. (19.72 ± 1.77) beats/min, 41.67%(10/24) vs. 14.58%(14/96), (211.67 ± 85.38) ng/L vs. (167.86 ± 71.88) ng/L, (110.17 ± 19.13) scores vs. (89.09 ± 12.63) scores, (1 068.58 ± 230.65) × 10 9/L vs. (784.22 ± 233.98)×10 9/L, there were statistical differences ( P<0.05). Multivariate Logistic regression analysis showed that age, heart rate, PESI score and SII were the independent risk factors of death related to pulmonary embolism in APE patients ( P<0.05). The results of ROC curve showed that the area under curve of PESI and SII for the prediction of pulmonary embolism related death was 0.816 and 0.791, respectively, there was no statistical difference ( P>0.05). According to the cut-off of SII (882.40 × 10 9/L), they also assigned to the SII<882.40 × 10 9/L group (61 cases) and the SII≥882.40 × 10 9/L group (59 cases), The results of Kaplan-Meier survival analysis showed that the 6-month survival rate in the SII<882.40 × 10 9/L group was higher than that in the SII≥882.40 × 10 9/L group, there was statistical difference ( P<0.05). Conclusions:SII can effectively evaluate the survival prognosis of acute pulmonary embolism patients, and it can be used as one of the indicators for evaluating the prognosis of patients.
ABSTRACT
【Objective】 To investigate the predictive value of nutritional risk index (NRI), systemic immune inflammatory index (SⅡ) and triglyceride glucose (TyG) index on the condition and prognosis of patients with acute pancreatitis (AP). 【Methods】 A total of 173 AP patients were divided into mild acute pancreatitis (MAP) group (n=79), moderate acute pancreatitis (MSAP) group (n=44), and severe acute pancreatitis (SAP) group (n=50) according to their severity. All the 50 SAP patients were divided into death group (19 cases) and survival group (31 cases) according to the death situation. The NRI, SⅡ and TyG indexes of each group were recorded and compared.

Correlation analysis showed that NRI was negatively correlated with SⅡ and TyG index in SAP patients (r=-0.761, P<0.001, r=-0.813, P<0.001), while SⅡ was positively correlated with TyG index (r=0.842, P<0.001). 【Conclusion】 NRI, SⅡ and TyG index are related to the severity and death of AP patients, and the combination of the three indexes has good value in predicting the occurrence and prognosis of SAP.
ABSTRACT
ObjectiveTo summarize the characteristics of traditional Chinese medicine （TCM） syndrome in primary Sjögren's syndrome （pSS） patients with interstitial lung disease （ILD） and to explore associated factors. MethodA survey was conducted and pSS patients who were treated in TCM department of rheumatism at China-Japan Friendship Hospital from December 2018 to April 2022 were included. Tongue manifestations and syndromes of patients were recorded. pSS patients with ILD were classified into the pSS-ILD group and those without the ILD were included in the pSS-non-ILD group. The tongue manifestations， syndromes， and laboratory indexes were compared between the two groups， and logistic regression was used to explore the factors associated with pSS-ILD. ResultA total of 200 pSS patients were included， with 186 （93.0%） females， median age of 57 years， and median disease course of 60 months， of which 44 （22%） had pSS-ILD. In terms of tongue manifestations， pSS-ILD patients generally had dark/purple/stasis tongue， fissured tongue， and tongue with little fluid， thick coating， yellow coating， and greasy coating. The proportion patients with yellow coating was higher in pSS-ILD group than in the pSS-non-ILD group （χ2=4.799，P<0.05）. In terms of syndrome， more than 40% of pSS-ILD patients had Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. As for Yin deficiency， liver-kidney Yin deficiency syndrome ranked the first. For Qi deficiency， lung Qi deficiency syndrome was most commonly seen. The proportion of patients with lung Qi deficiency was higher in the pSS-ILD group than in the pSS-non-ILD group （χ2=18.667，P<0.01）. As to laboratory indexes， compared with the pSS-non-ILD group， pSS-ILD group had high proportion of anti-SSA-positive patients （P<0.05） and high levels of C-reactive protein （CRP） （P<0.01）， complement C3 （χ2=4.332，P<0.05）， and complement C4 （P<0.05）. Logistic regression analysis showed that pSS with ILD was positively associated with lung Qi deficiency ［odds ratio （OR）=6.079， 95% confidence interval （CI） 2.585-14.298， P<0.01）］ and yellow coating （OR=5.260， 95% CI 1.337-20.692， P<0.05） and negatively associated with low C4 （OR=0.199， 95% CI 0.070-0.564， P<0.01）. ConclusionAbout 22% of pSS patients had ILD， and patients with pSS-ILD generally have Qi deficiency， Yin deficiency， phlegm-dampness， Qi stagnation， and/or blood stasis syndrome. Yellow coating， lung Qi deficiency and C4 level are factors associated with pSS combined with ILD.
ABSTRACT
@#Objective To explore the association between the preoperative systemic immune-inflammation index (SII) and prognosis in non-small cell lung cancer (NSCLC) patients. Methods A comprehensive literature survey was performed on PubMed, Web of Science, EMbase, The Cochrane Library, Wanfang, and CNKI databases to search the related studies from inception to December 2021. The hazard ratio (HR) and 95% confidence interval (CI) were combined to evaluate the correlation of the preoperative SII with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) in NSCLC patients. Results A total of 11 studies involving 9 180 patients were eventually included. The combined analysis showed that high SII levels were significantly associated with worse OS (HR=1.61, 95%CI 1.36-1.90, P<0.001), DFS (HR=1.50, 95%CI 1.34-1.68, P<0.001), and RFS (HR=1.17, 95%CI 1.04-1.33, P<0.001). Subgroup analyses also further verified the above results. Conclusion Preoperative SII is a powerful prognostic biomarker for predicting outcome in patients with operable NSCLC and contribute to prognosis evaluation and treatment strategy formulation. However, more well-designed and prospective studies are warranted to verify our findings.

Results Among the 101 patients, 21(20.8%) experienced BC.The multivariate Logistic regression analysis showed that MELD score (odds ratio[ OR ]=0.134, 95% confidence interval[ CI ]: 0.031-0.590, P =0.008), SⅡ/Alb ( OR =1.415, 95% CI : 1.181-1.696, P =0.001), and plasma transfusion volume ( OR =1.001, 95% CI : 1.000-1.002, P =0.032) were independent risk factors for the development of BC in patients after liver transplantation.MELD score, SⅡ/Alb, plasma transfusion volume, MELD+SⅡ/Alb, and MELD+SⅡ/Alb+plasma transfusion volume had an area under the ROC curve of 0.712, 0.870, 0.712, 0.900, and 0.918, respectively, in predicting BC after liver transplantation. Conclusion SⅡ/Alb, plasma transfusion volume and MELD score are independent risk fators for BC after liver transplantation.The combination of three indicators has good predictive value and clinical guiding significance for BC after liver transplantation.
ABSTRACT
Objective:To investigate the value of immune inflammatory index in predic-ting the therapeutic efficacy of neoadjuvant chemoradiotherapy for esophageal squamous cell carci-noma (ESCC).Methods:The retrospective case-control study was conducted. The clinicopatholo-gical data of 163 patients with ESCC who were admitted to Zhongshan Hospital of Fudan University from December 2015 to December 2020 were collected. There were 135 males and 28 females, aged (62±8)years. All 163 patients underwent neoadjuvant chemoradiotherapy and radical resection for ESCC. Observation indicators: (1) relationship between immune inflammatory index and clinical characteristic in patients; (2) relationship between immune inflammatory index and efficacy of neoadjuvant chemoradiotherapy in patients; (3) influencing factor analysis for pathologic complete response and good response of tumor regression grade after neoadjuvant chemoradiotherapy; (4) efficiency of immune inflammatory index in predicting efficacy of neoadjuvant chemoradiotherapy. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was conducted using chi-square test. Comparison of ordinal data was conducted using the rank sum test. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value. Univariate and multi-variate analyses were conducted using the Logistic regression model. The area under the curve (AUC) of ROC curve was used to evaluate the efficiency of predictive model. Results:(1) Relationship between immune inflammatory index and clinical characteristic in patients. ① Optimal cut-off value of systemic immune-inflammation index (SII), neutrophil-lymphocyte ratio (NLR), platelet-lympho-cyte ratio (PLR). Results of ROC curve analysis showed that the AUC of SII, NLR, PLR in predicting efficacy of neoadjuvant chemoradiotherapy for patients with ESCC was 0.70(95% confidence interval as 0.61?0.77), 0.78(95% confidence interval as 0.69?0.84), 0.79(95% confidence interval as 0.70?0.85), respectively, with the maximum value of Youden index and the optimal cut-off value as 0.25, 0.32, 0.52 and 446×10 9/L, 2.09, 138. ② Relationship between SII, NLR, PLR and clinical charac-teristic in patients. According to the optimal cut-off value of SII, NLR, PLR, all 163 patients were divided into cases with SII <446×10 9/L as 99, cases with SII ≥446×10 9/L as 64, cases with NLR <2.09 as 107, cases with NLR ≥2.09 as 56, cases with PLR<138 as 88, cases with PLR ≥138 as 75, respectively. There was a significant difference in clinical N staging of tumor in patients with SII <446×10 9/L and SII ≥446×10 9/L ( P<0.05). There were significant differences in clinical N staging and clinical TNM staging of tumor in patients with NLR<2.09 and NLR≥2.09 ( P<0.05). (2) Relationship between immune inflammatory index and efficacy of neoadjuvant chemoradiotherapy in patients. Of 163 patients undergoing neoadjuvant chemoradiotherapy, there were 54 cases with pathologic complete response and 109 cases without pathologic complete response, 94 cases with good response of tumor regression grade and 69 cases with poor response of tumor regression grade. Of the 54 patients with pathologic complete response, cases with SII <446×10 9/L and SII ≥446×10 9/L, cases with NLR <2.09 and NLR ≥2.09, cases with PLR <138 and PLR ≥138 before neoadjuvant chemoradiotherapy were 42 and 12, 47 and 7, 48 and 6, respectively. The above indicators were 57 and 52, 60 and 49, 40 and 69 in the 109 cases without pathologic complete response. There were significant differences in the above indicators between patients with pathologic complete response and without pathologic complete response ( χ2=9.83, 16.39, 39.60, P<0.05). Of the 94 cases with good response of tumor regression grade, cases with SII <446×10 9/L and SII ≥446×10 9/L, cases with NLR <2.09 and NLR ≥2.09, cases with PLR <138 and PLR ≥138 before neoadjuvant chemoradiotherapy were 59 and 35, 78 and 16, 56 and 38, respectively. The above indicators were 40 and 29, 29 and 40, 32 and 37 in the 69 cases with poor response of tumor regression grade. There was no significant difference in the SII and PLR ( χ2=0.38, 2.79, P>0.05) and there was a significant difference in the NLR ( χ2=29.59, P<0.05) between patients with good response of tumor regression grade and poor response of tumor regre-ssion grade. (3) Influencing factor analysis for pathologic complete response and good response of tumor regression grade after neoadjuvant chemoradiotherapy. Results of multivariate analysis showed that PLR <138 before neoadjuvant chemoradiotherapy was an independent protective factor for pathologic complete response in ESCC patients undergoing neoadjuvant chemoradiotherapy ( odds ratio=1.98, 95% confidence interval as 1.56?2.51, P<0.05) and NLR <2.09 before neoadjuvant chemo-radiotherapy was an independent protective factor for good response of tumor regression grade ( odds ratio=2.50, 95% confidence interval as 1.40?4.46, P<0.05). (4) Efficiency of immune inflam-matory index in predicting efficacy of neoadjuvant chemoradio-therapy. The AUC of PLR <138 before neoadjuvant chemoradiotherapy in predicting pathologic complete response of ESCC patients undergoing neoadjuvant chemoradiotherapy was 0.79(95% confidence interval as 0.64?0.87, P<0.05), with the sensitivity, specificity and Youden index as 0.89, 0.63 and 0.52, respectively. The AUC of NLR <2.09 before neoadjuvant chemoradiotherapy in predic-ting good response of tumor regression grade of ESCC patients undergoing neoadjuvant chemoradio-therapy was 0.76 (95% confidence interval as 0.64?0.81, P<0.05), with the sensitivity, specificity and Youden index as 0.83, 0.58 and 0.41, respectively. Conclusion:The PLR<138 and NLR <2.09 before neoadjuvant chemoradiotherapy are independent protective factors for the pathologic complete response and good response of tumor regression grade, respectively, of ESCC patients undergoing neoadjuvant chemoradiotherapy, and both of them can predict the curative effect of neoadjuvant chemoradiotherapy well.
ABSTRACT
Objective:To explore the predictive value of systemic immune inflammation index (SII) for the risk of hospital death in critically ill patients.Methods:The basic information and clinical data of critically ill patients were extracted from the Medical Information Mart for Intensive Care database-Ⅳ (MIMIC-IV) database, including demographic data, vital signs, blood routine, Logistic organ dysfunction score (Lods), Oxford acute severity of illness score (Oasis), simplified acute physiology score (Saps-Ⅱ), acute physiology score Ⅲ (APS-Ⅲ), sequential organ failure score (SOFA) and outcome. The main outcome was hospital death, and the secondary outcomes were length of hospital stay, continuous renal replacement therapy (CRRT), invasive ventilation and 1-year mortality. Patients were divided into two groups according to in-hospital death, and the differences between the groups were compared. According to the SII tripartite for inter-group comparison, the patients were further divided into three groups for comparison, and Logistic regression model was used to analyze the odd ratio ( OR) of the three groups. Results:A total of 32 450 critically ill patients were included in the study, of which 3765 died in hospital, with a mortality rate of 11.6%. ① Compared with the survival group, the SII in the death group were significantly higher ( P < 0.05). ② The mortality for the SII tripartite grouping (<817; 817~2 151; >2 151) were 8.4%, 10.2% and 16.3%, respectively, and the differences between groups were statistically significant. ③ Further, Logistic regression model analysis showed that the risk of death increased gradually with the increase of groups (the first group was the reference group, OR of the second group was 1.38, 95% CI 1.24-1.54, and OR of the third group was 2.03, 95% CI 1.83-2.24 ( P < 0.05). Conclusions:SII has a certain value in predicting hospital death in critically ill patients. It is easy to obtain and can be used for risk stratification of critically ill patients.
ABSTRACT
This article aimed to explore the theoretical connotation and mechanism of clearing damp-heat method in the treatment of chronic kidney disease (CKD), provide theoretical support for clearing damp-heat method in the treatment of chronic kidney disease, and further explain the modern scientific connotation of "damp-heat impairing kidney". Modern Traditional Chinese Medicine (TCM) believes that damp-heat is an important pathogenesis of kidney damage. Clearing damp-heat method plays a key role in inhibiting CKD immune inflammatory response, improving oxidative stress and antagonizing renal fibrosis. The mechanism is mainly related to the regulation of TNF-α level, blocking NF-κB signaling pathway, inhibiting inflammatory cytokines, antagonizing TGF-β1 secretion and other pathways.

Objective:To explore the predictive value of neutrophil to lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) of inflammatory markers of peripheral blood cells on the prognosis in the advanced non-small cell lung cancer (NSCLC) patients with immune therapy.Methods:The hematologic and clinical data of 58 patients with advanced non-small cell lung cancer who received the treatment of immune therapy in the First People's Hospital of Chuzhou of Anhui Province from January 2018 to June 2022 were retrospectively analyzed. X-tile software was used to calculate the optimal cut-off values of NLR and SII. All patients were divided into high and low groups according to the optimal cut-off values. The relationship between different NLR, SII and clinicopathological features, clinical efficacy, prognosis of the advanced non-small cell lung cancer patients with immune therapy were analyzed. Cox regression models were used to perform univariate and multivariate analyses of factors affecting patient prognosis.Results:The optimal cut-off values for NLR and SII were 3.2 and 546.5, respectively. There were statistically significant differences in regional lymph node metastasis ( χ2=5.03, P=0.025) and the number of metastatic sites ( χ2=11.60, P=0.001) between patients in the low-NLR group (NLR<3.2, n=26) and the high-NLR group (NLR≥3.2, n=32). There were statistically significant differences in location of the primary site ( χ2=8.34, P=0.004) between patients in the low-SII group (SII<546.5, n=28) and the high-SII group (SII≥546.5, n=30). The objective response rate (ORR) of the low-NLR group [50.00% (13/26) ] was higher than that of the high-NLR group [21.88% (7/32) ], and there was a statistically significant difference ( χ2=5.02, P=0.025) ; the disease control rate (DCR) of the low-NLR group [69.23% (18/26) ] was higher than that of the high-NLR group [50.00% (16/32) ], but there was no statistically significant difference ( χ2=2.19, P=0.139). The ORR of the low-SII group [53.57% (15/28) ] was higher than that of the high-SII group [26.67% (8/30) ]; The DCR of the low-SII group [67.86% (19/28) ] was higher than that of the high-SII group [33.33% (10/30) ], and there were statistically significant differences ( χ2=4.38 , P=0.036; χ2=6.91 , P=0.009). The median overall survival (OS) of patients in the low-NLR group (17.6 months) was longer than that of the high-NLR group (11.7 months), and there was a statistically significant difference ( χ2=11.07, P=0.001). The median OS of patients in the low-SII group (16.5 months) was longer than that of the high-SII group (12.3 months), and there was a statistically significant difference ( χ2=5.53, P=0.019). Univariate analysis showed that Eastern Cooperative Oncology Group (ECOG) score ( HR=2.20, 95% CI: 1.10-4.39, P=0.025), brain metastases ( HR=3.24, 95% CI: 1.61-6.50, P=0.001), the number of transferred sites ( HR=2.83, 95% CI: 1.44-5.57, P=0.003), NLR ( HR=3.22, 95% CI: 1.56-6.66, P=0.002) and SII ( HR=2.18, 95% CI: 1.12-4.24, P=0.021) were all independent influence factors affecting the prognosis of the advanced non-small cell lung cancer patients with immune therapy; multivariate analysis showed that brain metastases ( HR=2.91, 95% CI: 1.22-6.94, P=0.016), NLR ( HR=2.88, 95% CI: 1.17-7.13, P=0.022) and SII ( HR=3.63, 95% CI: 1.40-9.39, P=0.008) were all independent risk factors affecting the prognosis of the advanced non-small cell lung cancer patients with immune therapy. Conclusion:NLR and SII can be used as important indicators for predicting the efficacy of immunotherapy in the advanced NSCLC and elevated NLR and SII can indicate poor prognosis of patients.
ABSTRACT
Objective To investigate the predictive value of preoperative fibrinogen/albumin ratio (FAR) and systemic immune inflammation index (SII) on the postoperative prognosis of patients with pancreatic ductal adenocarcinoma. Methods An ROC curve was used in determining the best cutoff values of FAR and SII and then grouped. The Cox proportional hazards model was used in analyzing the prognostic factors of radical pancreatic cancer surgery, and then a Nomogram prognostic model was established. C-index, AUC, and calibration curve were used in evaluating the discrimination and calibration ability of the Nomogram. DCA curves were used in assessing the clinical validity of the Nomograms. Results The optimal cutoff values for preoperative FAR and SII were 0.095 and 532.945, respectively. FAR≥ 0.095, SII≥ 532.945, CA199≥ 450.9 U/ml, maximum tumor diameter≥ 4 cm, and the absence of postoperative chemotherapy were independent risk factors for the poor prognosis of pancreatic cancer (P<0.05). The discrimination ability, calibration ability, and clinical effectiveness of Nomogram prognostic model were better than those of the TNM staging system. Conclusion The constructed Nomogram prognostic model has higher accuracy and level of discrimination and more clinical benefits than the TNM staging prognostic model.
ABSTRACT
Objective To explore the correlation of the pan-immune-inflammation value (PIV) and the prognosis of patients with resectable colorectal cancer (CRC) and establish a predictive model. Methods A total of 753 patients who underwent primary lesion resection and were pathologically diagnosed with CRC were enrolled. They were randomly divided into training (n=527) and test (n=226) cohorts. The best cutoff value of PIV was determined by the time-dependent receiver operator characteristics curve, and patients were divided into high- and low-level groups to analyze the relationship between the high- and low-level groups of PIV and the clinicopathological characteristics and survival of patients. Chi-square test, Kaplan-Meier survival analysis, and Cox regression analysis were used to evaluate the prognosis. The accuracy of the model was evaluated by C index and Brier score. Results In the univariate model of overall survival (OS), high (> 231) baseline PIV (HR=1.627; 95%CI: 1.155-2.292, P=0.005) suggested that PIV level might be an independent prognostic factor for OS. The nomogram plotted according to PIV had a C index of 0.823. Its calibration curve showed good agreement between predicted and observed outcomes for one- and three-year OS probabilities, with Brier score of 0.035 and 0.068 for OS, respectively. Conclusion PIV can be used as a prognostic marker in patients with resectable CRC, and a novel prognostic model to guide clinical decision-making in CRC is successfully established.
ABSTRACT
Background:Post?cardiotomy vasoplegia syndrome (VS) is often linked to an exaggerated inflammatory response to cardiopulmonary bypass (CPB). At the same time, the prognostic role of platelet?leucocyte indices (PLIs) and leucocyte indices (LIs), (platelet?lymphocyte ratio [PLR], systemic immune?inflammation index [SII = platelet neutrophil/lymphocyte], aggregate index of systemic inflammation [AISI = platelet monocyte neutrophil/lymphocyte], and neutrophil?lymphocyte ratio [NLR], systemic inflammation response index [SIRI = monocyte neutrophil/lymphocyte), respectively] has been recently described in diverse inflammatory settings. Methods: The retrospective study was conducted to evaluate the VS predictive performance of PLIs and LIs in 1,045 adult patients undergoing elective cardiac surgery at a tertiary care center. VS was defined by mean blood pressure <60 mmHg, low systemic vascular resistance (SVRI <1,500 dynes.s/cm 5/m2 ), a normal or high CI (>2.5 L/min/m2 ), and a normal or reduced central filling pressure despite high?dose vasopressors. Results: About 205 (19.61%) patients developed VS postoperatively. On univariate analysis, age, diabetes, dialysis?dependent renal failure, preoperative congestive heart failure (CHF), the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, ejection fraction, NLR, PLR, SII, SIRI, AISI, CPB, and aortic cross clamp (ACC) duration, packed red blood cell (PRBC) transfusion, and time?weighted average blood glucose predicted VS. Subsequent to the multivariate analysis, the predictive performance of EuroSCORE II (OR: 3.236; 95% CI: 2.345–4.468; P < 0.001), CHF (OR: 1.04; 95% CI: 1.02–1.06; P = 0.011), SII (OR: 1.09; 95% CI: 1.02–1.18; P = 0.001), AISI (OR: 1.11; 95% CI: 1.05–1.17; P < 0.001), PRBC (OR: 4.747; 95% CI: 2.443–9.223; P < 0.001), ACC time (OR: 1.003; 95% CI: 1.001–1.005; P = 0.004), and CPB time (OR: 1.016; 95% CI: 1.004–1.028; P = 0.001) remained significant. VS predictive cut?offs of SII and AISI were 1,045 1045×109 /mm3 and 137532×109 /mm3 , respectively. AISI positively correlated with the postoperative vasoactive?inotropic score (R = 0.718), lactate (R = 0.655), mechanical ventilation duration (R = 0.837), and ICU stay (R = 0.757). Conclusions: Preoperative elevated SII and AISI emerged as independent predictors of post?cardiotomy VS.
ABSTRACT
ABSTRACT Background: Low-grade inflammation is known to facilitate the development of hypertensive organ damage. The systemic immune-inflammation index (SII) is a new inflammatory index based on circulating immune-inflammatory cells. Objectives: The objectives of this study were to investigate the relationship between the SII and asymptomatic organ damage (AOD) in patients with newly diagnosed treatment-naive hypertension (HTN). Methods: A total of 500 participants (≥ 18 years) were enrolled in the study, including 250 patients and 250 healthy volunteers. Microalbuminuria of > 30 mg/day or proteinuria of > 150 mg/day, left ventricular mass index of > 95 g/m2 in women and > 115 g/m2 in men, and carotid intima-media thickness of > 0.9 mm or the presence of plaque in the carotid were evaluated as AOD indicators. AOD grade was classified as follows: Grade I - One organ involved, Grade II - Two organs involved, Grade III - Three organs involved, and Grade IV - Four organs involved. Results: SII values were higher among patients with HTN than in the control group. Positive correlations were found between the SII and AOD indicators and C-reactive protein levels. Increasing SII values were a common independent predictor of the presence and severity of AOD. The gradually increasing threshold values of the SII from no AOD to Grade III-IV exhibited high diagnostic performance. Conclusions: High SII values were independent predictors of the presence and severity of AOD in patients with newly diagnosed treatment-naive HTN. Considering the role of inflammation in HTN, the SII, which can be easily evaluated using blood parameters, can be an effective prognostic screening tool.
ABSTRACT
Abstract Objectives: Recurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find the possible diagnostic correlation between Systemic Immune Inflammation Index (SII). Methods: Patients who were consulted the otolaryngology outpatient clinic and diagnosed with RAS between 2019-2021 were retrospectively analyzed. Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR) and SII values were calculated based on the results of complete blood count. Demographic and hematological parameters between control and RAS groups were compared. The statistical significance level was considered as <0.05. Results: There was no statistically significant difference between the control and RAS groups in terms of sex and age distributions (p = 0.566 and p = 0.173, respectively). SII, NLR and PLR values were significantly higher in the RAS group compared to the controls (p < 0.001, p < 0.001 and p = 0.001, respectively). A very strong correlation between SII and NLR, moderately strong correlation between SII and PLR and moderate correlation between NLR and PLR values were detected (respectively ρ: 0.813, 0.719, 0.532; p-values <0.001). Conclusion: SII, NLR and PLR has significantly higher levels in the RAS group compared to the control group, that it supports the role of systemic inflammation in the etiopathogenesis of RAS. In addition, the results show that SII is a valuable marker for inflammation. Level of evidence: 4. HIGHLIGHTS RAS is a chronic, idiopathic, ulcerative oral mucosal disease. SII is a new and inexpensive biomarker that can easily be calculated using the platelet, neutrophil, and lymphocyte count. SII may be a valuable marker to demonstrate the role of systemic inflammation in RAS etiopathogenesis. Vascular, thrombotic, and inflammatory processes are thought to have a role in RAS activation.
Resumo Objetivo: A estomatite aftosa recorrente (EAR) é uma doença crônica idiopática da mucosa oral. Embora sua etiologia e patogênese não sejam totalmente conhecidas, acredita-se que a inflamação possa desempenhar um papel importante. O objetivo deste estudo é demonstrar o papel da inflamação sistêmica entre os possíveis fatores etiológicos da estomatite aftosa recorrente e encontrar uma possível correlação diagnóstica com o índice de inflamação imunológica sistêmica, SII. Método: Foram analisados retrospectivamente pacientes avaliados no ambulatório de otorrinolaringologia e diagnosticados com estomatite aftosa recorrente entre 2019-2021. A relação neutrófilos/linfócitos, a relação plaquetas/linfócitos e os valores de SII foram calculados com base nos resultados do hemograma completo. Parâmetros demográficos e hematológicos dos grupos controle e de pacientes foram comparados. O nível de significância estatística foi considerado como <0,05. Resultados: Não houve diferença estatisticamente significante entre os grupos controle e com estomatite aftosa recorrente quanto à distribuição por sexo e idade (p = 0,566 e p = 0,173, respectivamente). Os valores de SII, a relação neutrófilos/linfócitos e a relação plaquetas/linfócitos foram significantemente maiores no grupo de pacientes em relação aos controles (p <0,001, p <0,001 e p = 0,001, respectivamente). Foi detectada uma correlação muito forte entre SII e relação neutrófilos/linfócitos, uma correlação moderadamente forte entre SII e relação plaquetas/linfócitos e uma correlação moderada entre valores da relação neutrófilos/linfócitos e relação plaquetas /linfócitos (ρ: 0,813, 0,719, 0,532 respectivamente; p-valores <0,001). Conclusão: SII, relação neutrófilos/linfócitos e relação plaquetas/linfócitos apresentam níveis significantemente maiores no grupo com estomatite aftosa recorrente quando comparados ao grupo controle, o que corrobora o papel da inflamação sistêmica na sua etiopatogênese. Além disso, os resultados mostram que o SII é um marcador inflamatório valioso. Nível de evidência: 4. HIGHLIGHTS A estomatite aftosa recorrente é uma doença ulcerativa crônica idiopática da mucosa oral. O SII (do inglês Systemic Immune Inflammation Index) é um biomarcador novo e de baixo custo que pode ser facilmente calculado que usa a contagem de plaquetas, neutrófilos e linfócitos. O SII pode ser um marcador valioso para demonstrar o papel da inflamação sistêmica na etiopatogênese da estomatite aftosa recorrente. Acredita-se que processos vasculares, trombóticos e inflamatórios tenham um papel na ativação da estomatite aftosa recorrente.
ABSTRACT
Objective:To explore the expression features of cytochrome C oxidase subunit Ⅰ (MT-CO1), BCL2 interacting protein 3 (BNIP3) and interleukin (IL)-1β in the liver of MRL/lpr lupus mice.Methods:The mRNA and protein levels of MT-CO1, BNIP3, IL-1β, p16 and p21 in lupus mice and control mice were detected by polymerase chain reaction (PCR) and Western blot, the IL-1β expression site were detected by hematoxylin and eosin (HE) staining and immunohistochemical method, and themalondialdehyde (MDA) was detected by colorimetry. Hepatocytes and macrophages were stimulated with lipopolysaccharide (LPS), while hepatocytes were also cultured with supernatants obtained after macrophages stimulated with LPS, and the mRNA and protein levels of MT-CO1, BNIP3 and LC3B, as well as p16 and p21 expression, were determined by qPCR and Western blot. The expression of mitochondrial reactive oxygen species (mtROS) was detected by immunofluorescence. One way Analysis of Variance (ANOVA) was used to compare the mean of each group, and LSD method was used to compare the means of multiple samples, and Tamhane's T2 method was used to compare the means of multiple samples when the variance was uniform. Results:The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the liver tissue of the lupus group (0.14±0.04; 0.16±0.05) were significantly lower than those of the control group (0.11±0.04; 0.16±0.06), and the differences were statistically significant ( t=7.16, P<0.001; t=4.54, P<0.001). The expression levels of IL-1β, p16 and p21 in the lupus group (2.06±0.69; 0.37±0.14; 0.16±0.06) were significantly higher than those of the control group (0.23±0.06; 0.25±0.08; 0.11±0.04) ( t=9.58, P<0.001; t=24.35, P<0.001; t=22.36, P<0.001). The results of Western blot were consistent with those of PCR. HE staining showed lymphocyte infiltration in the liver tissue of lupus mice, and immunohistochemistry showed IL-1β in the liver tissue of lupus mice. The positive cells were mainly concentrated in the sinusoids, and the expression of hepatic parenchymal cells was not rearkable. The content of MDA in liver tissue of the lupus group (0.19±0.10) was higher than that of the control group (0.17±0.09), and the difference was statistically significant ( t=4.33, P=0.005). LPS directly stimulated AML12 hepatocytes (0.069±0.028; 0.17±0.07). The PCR results showed that compared with the control group (0.176±0.072; 0.08±0.03), the expression of MT-CO1, and BNIP3 were not significantly different ( t=1.01, P=0.337; t=0.88, P=0.399). The expression of IL-1β was significantly higher when incubated with the supernatants of LPS stimulated macrophages (0.28±0.09) compared than that of the control group (0.15±0.05) ( t=28.26, P<0.001). The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the LPS stimulated group (0.046±0.026; 0.17±0.05) were significantly lower than those in the control group (0.143±0.083; 0.18±0.06), and the differences were statistically significant ( t=7.52, P<0.001; t=4.24, P<0.001), The expression of p16 and p21 in LPS stimulated group (0.29±0.09; 0.27±0.09) were significantly higher than those in the control group (0.18±0.06; 0.22±0.07) ( t=13.54, P<0.001; t=8.69, P<0.001). The results of Western blot were consistent with those of PCR. Immunofluorescence showed that the fluorescence intensity of mtROS in LPS stimulated group (0.25±0.10) was higher than that in the control group (0.08±0.03), and the difference was statistically significant ( t= 4.86, P<0.001). Conclusion:Immune-mediated inflammation in the liver tissue of lupus mice can stimulate liver parenchymal cells to cause intracellular mitochondrial dysfunction. However, the mechanism of liver organ damage in lupus mice is not limited to the immune-mediated inflammation of immune active cells, but also include parenchymal cell mitochondrial dysfunction.
ABSTRACT
Objective:To investigate the prognostic value of thymosin β4 (TMSB4X) expression and preoperative systemic immune-inflammatory index/serum albumin (SII/ALB) level in patients with early operable non-small cell lung cancer (NSCLC).Methods:A total of 128 patients with early NSCLC admitted to Zibo Central Hospital from January 2016 to January 2021 were selected. TMSB4X and SII/ALB were detected before surgery, and they were divided into TMSB4X positive group (52 cases) and TMSB4X negative group (76 cases) according to TMSB4X expression. According to the median SII/ALB value, the patients were divided into high SII/ALB group (64 cases) and low SII/ALB group (64 cases). The relationship between TMSB4X, SII/ALB and clinical characteristics in patients with early operable NSCLC was analyzed. The survival curve was drawn by Kaplan-Meier method and the difference of progression free survival (PFS) between TMSB4X positive group and negative group, high SII/ALB group and low SII/ALB group was tested by log-rank. The influencing factors of PFS was analyzed by Cox univariate and multivariate regression.Results:There were difference in lesion site, carcinoembryonic antigen (CEA) and lymphocyte count (LY) between TMSB4X positive group and TMSB4X negative group (all P<0.05). There were significant difference in age, American Joint Committee on Cancer (AJCC) stage, ALB, cytokeratin 19 fragment (CYFRA21-1), CEA, LY, platelet count (PLT) between the high SII/ALB group and the low SII/ALB group (all P<0.05). The median PFS of TMSB4X positive group (17.11 months) was lower than that of TMSB4X negative group (26.64 months) (log rank P<0.001); The median PFS (15.82 months) in the high SII/ALB group was lower than that in the low SII/ALB group (28.24 months) (log rank P<0.0001); Cox univariate analysis showed that lesion location, AJCC stage, ALB, CYFRA21-1, CEA, LY, PLT, TMSB4X, and SII/ALB were all factors influencing PFS in early operable NSCLC patients (all P<0.05); Multivariate analysis showed that AJCC stage, LY, TMSB4X, SII/ALB were independent factors influencing PFS in early operable NSCLC patients (all P<0.05). Conclusions:The expression of TMSB4X and the preoperative level of SII/ALB can be used as prognostic indicators for patients with early operable NSCLC.
ABSTRACT
Alzheimer's disease （AD） is a neurological disease highly related to age， which is the main cause of senile dementia and the most common disease leading to the loss of daily living ability of the elderly. AD brings heavy mental burden and economic pressure to patients， families， and society. Traditional Chinese medicine （TCM） ascribes AD to category of "dementia"， believing that the treatment should start from kidney because kidney deficiency is the root cause. Combined with the physiological and pathological characteristics of liver， this paper proposed that liver-kidney homology was an important idea for the prevention and treatment of AD. The main pathological manifestations of AD were amyloid β-protein （Aβ） deposition and neurofibrillary tangles （NFT）， and the pathogenesis was complex. A growing number of studies showed that immune inflammation played an important role in the pathogenesis of AD. The important target of treating AD was the regulation of neuro-immune inflammation through the nuclear factor kappa B （NF-κB）/NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/Caspase-1/interleukin-1β （IL-1β） signaling pathway. Based on the idea of liver-kidney homology， this paper selected the representative formula Hei Xiaoyaosan to explore its effect on the prevention and treatment of AD and the mechanism from the perspective of regulating NF-κB/NLRP3/Caspase-1/IL-1β signaling pathway and inhibiting neuro-immune inflammation， expecting to further promote the in-depth study on the prevention and treatment of AD， and provide references for the prevention and treatment of AD by TCM.
