Objective Urine levels of immunoglobulin binding protein 1 (IGBP1) are increased in patients with lupus nephritis (LN) compared with systemic lupus erythematosus (SLE) patients without nephritis. However, the clinical significance of IGBP1 level in plasma is unclear. We aimed to evaluate whether the plasma level of IGBP1 can predict future development of LN in SLE patients without nephritis. Methods Forty-three SLE patients without nephritis were followed for 5 years. Plasma IGBP1 levels were measured using ELISA, and clinical and laboratory data were obtained at study entry. Development of LN was confirmed by renal biopsy. Cox regression analysis was performed to identify factors associated with development of LN, and receiver operating characteristic curve analysis was used to determine the predictive value of each factor. Results Of the total 43 patients, eight (18.6%) developed LN during the follow-up period. Compared with patients who did not develop LN, those who developed LN had higher levels of plasma IGBP1 (6.3 ng/ml (range 4.3–9.6 ng/mL) vs. 13.3 ng/ml (range 7.2–31.3 ng/ml); p =  0.023). In the Cox regression analysis, higher CRP (hazard ratio (HR) = 1.325, 95% confidence interval (CI) 1.073–1.637, p =  0.009), anti-dsDNA antibody (Ab; HR = 1.066, 95% CI 1.012–1.124, p =  0.017) and plasma IGBP1 (HR = 1.091, 95% CI 1.034–1.152, p =  0.002) were associated with future development of LN. Among these factors, anti-dsDNA Ab (area under the curve (AUC)=0.893) had the highest predictive value followed by plasma IGBP1 (AUC = 0.761) and CRP (AUC = 0.634). A combination of anti-dsDNA Ab and plasma IGBP1 as a composite predictor was highly specific (97%) for predicting the development of LN. Conclusions Plasma IGBP1 can be used complementarily with anti-dsDNA Ab for detecting SLE patients at a higher risk of developing LN.

ObjectivesTo examine the rates of acute myocardial infarction (AMI) and ischaemic stroke (IS) and to examine the predictive value of total cholesterol (TC) and triglycerides (TG) for AMI and IS in patients with rheumatoid arthritis (RA) and people without RA.MethodsIn the Apolipoprotein MOrtality RISk (AMORIS) Study 480 406 people (including 1779 with RA, of whom 214 had an AMI and 165 an IS) were followed for 11.8 (range 7–17) years. Cox regression analysis was used to calculate HR per SD increase in TC or TG with 95% CI. All values were adjusted for age, diabetes and hypertension.ResultsThe levels of TC and TG were significantly lower in patients with RA than in people without RA. Despite this, the rate of AMI and IS per 1000 years was at least 1.6 times higher in RA than non-RA. TC was nearly significantly predictive for AMI (HR/SD 1.13 (95% CI 0.99 to 1.29), p=0.07) and significantly predictive for future IS in RA (HR/SD 1.20 (95% CI 1.03 to 1.40), p=0.02). TG had no relationship to development of AMI (1.07, 0.94 to 1.21, p=0.29), but was weakly related to IS (1.13, 0.99 to 1.27, p=0.06). In contrast, both TC and TG were significant predictors of AMI and IS in people without RA.ConclusionsPatients with RA had 1.6 times higher rate of AMI and IS than people without RA. TC and TG were significant predictors of AMI and IS in people without RA, whereas the predictive value in RA was not consistent.

We evaluated the role of immunoglobulin binding protein 1 (IGBP1), a phosphoprotein associated with the B cell receptor (BCR) complex, as a urine biomarker in lupus nephritis (LN). The IGBP1 concentrations in plasma and urine of patients with LN, systemic lupus erythematosus (SLE) without nephritis and healthy controls were estimated by ELISA. IGBP1 expression in the kidneys of LN patients and transplantation donors was detected by immunohistochemistry. Microarray-based global gene expression profile of HK-2 cells with IGBP1 knock-down and fluorescence-activated cell sorting (FACS) for intracellular IGBP1 expression in human peripheral blood mononuclear cells (PBMCs) was performed. Urine IGBP1 levels were elevated significantly in LN patients, and it correlated with the clinical activity indices (complement 3 (C3) level, anti-dsDNA antibodies titer, SLE Disease Activity Index-2000 (SLEDAI-2K) and histological activity index. IGBP1 expression was increased in LN patients as compared to the donors and was detected mainly in the tubules by histopathology. In microarray analysis, several genes related to SLE pathogenesis (PPME1, ROCK2, VTCN1, IL-17R, NEU1, HLA-DM, and PTX3) responded to siRNA-mediated IGBP1 silencing. In FACS, IGBP1 was expressed mainly in the CD14+ cells. The overall expression of IGBP1 in PBMCs was higher in LN patients as compared with that in SLE patients without nephritis. Conclusively, urinary IGBP1 may be a novel biomarker reflecting the clinical and histological activities in LN.

Abstract Objective: To explore the prognostic significance and underlying mechanism of TYRO protein tyrosine kinase-binding protein (TYROBP) in osteosarcoma. Methods: Firstly, the expression of TYROBP was analyzed using the t-test. The Kaplan-Meier plotter analysis and a receiver operating characteristic (ROC) curve were performed to evaluate the influence of TYROBP on overall survival (OS). Further, Cox regression analysis was conducted to predict the independent prognostic factors for OS of osteosarcoma patients, and a nomogram was constructed. Then, the relationship between TYROBP and clinicopathological characteristics was determined using statistical methods. Enrichment analyses were conducted to evaluate the biological functions of TYROBP. Finally, ESTIMATE algorithm was used to assess the association of TYROBP with immune cell infiltration. Results: TYROBP was significantly increased in osteosarcoma (all P <0.001). However, the high expression of TYROBP was related to better OS of osteosarcoma patients. Cox regression analysis showed that TYROBP was an independent prognostic factor for predicting OS (P =0.005), especially in patients with male sex, age <18 years, metastasis, and tumor site leg/foot (all P <0.05). Besides, TYROBP mRNA expression was significantly associated with tumor site (P <0.01) but had no remarkable relationship with age, gender, and metastasis status (all P>0.05). Functional annotation and GSEA revealed that TYROBP was mainly involved in immune-related pathways. Importantly, TYROBP positively correlated with immune scores (P <0.001, r=0.87). Conclusions: TYROBP served as an independent prognostic biomarker for OS in osteosarcoma. High TYROBP expression might prolong the survival of osteosarcoma patients mainly through promoting antitumor immunity.

Abstract Background: Objective to evaluate the predictive value of preoperative fibrinogen and systemic inflammatory response index (F-SIRI) in the prognosis of patients with hepatocellular carcinoma after radical hepatectomy. Methods: the clinical data of 298 patients with hepatocellular carcinoma who underwent surgery and confirmed by postoperative pathology in our hospital from January 2015 to December 2017 were retrospectively analyzed. The F-SIRI score was calculated according to FIB and SIRI data of peripheral blood. The relationship between F-SIRI score and clinicopathological characteristics was analyzed. The survival analysis was performed by Kaplan Meier method, Cox regression analysis was used to analyze the prognostic factors. Results: preoperative F-SIRI score was correlated with tumor diameter, FIB and SIRI (P<0.05), but not with age, gender, TNM stage and other clinical features (P>0.05). There were significant differences in the 5-year DFS rate and OS rate among patients with different preoperative F-SIRI scores(P<0.05); Cox regression analysis showed that preoperative tumor diameter, alpha fetoprotein level and F-SIRI score were independent predictors of DFS in patients with HCC (P< 0.05), while preoperative tumor diameter, ALB and F-SIRI score as independent predictors of OS (P<0.05). Conclusion: preoperative F-SIRI is an independent prognostic factor in patients with HCC after radical hepatectomy, with poor prognosis in patients with high level of F-SIRI.

Background: Depression and anxiety after stroke are common conditions that are likely to be neglected. Abnormal red blood cell (RBC) indices may be associated with neuropsychiatric disorders. However, the association of RBC indices with post-stroke depression (PSD) and poststroke anxiety (PSA) has not been sufficiently investigated. Methods: We aimed to investigate the trajectory of post-stroke depression and anxiety in our follow- up stroke clinic at 1, 3, and 6 months, and the association of RBC indices with these. One hundred and sixty-two patients with a new diagnosis of ischemic stroke were followed up at 1, 3, and 6 months, and underwent Patient Health Questionnaire-9 (PHQ-9) and the general anxiety disorder 7-item (GAD-7) questionnaire for evaluation of depression and anxiety, respectively. First, we used Kaplan-Meier analysis to investigate the accumulated incidences of post-stroke depression and post-stroke anxiety. Next, to explore the association of RBC indices with psychiatric disorders after an ischemic stroke attack, we adjusted for demographic and vascular risk factors using multivariate Cox regression analysis. Results: Of the 162 patients with new-onset of ischemic stroke, we found the accumulated incidence rates of PSD (1.2%, 17.9%, and 35.8%) and PSA (1.2%, 13.6%, and 15.4%) at 1, 3, and 6 months, respectively. The incident PSD and PSA increased 3 months after a stroke attack. Multivariate Cox regression analysis indicated independent positive associations between PSD risk and higher mean corpuscular volume (MCV) (OR=1.42, 95% CI=1.16-1.76), older age (OR=2.63, 95% CI=1.16-5.93), and a negative relationship between male sex (OR=0.95, 95% CI=0.91-0.99) and PSA. Conclusion: The risks of PSD and PSA increased substantially 3 months beyond stroke onset. Of the RBC indices, higher MCV, showed an independent positive association with PSD.

Abstract Background Breast cancer is one of the main malignant tumors that threaten the lives of women, which has received more and more clinical attention worldwide. There are increasing evidences showing that the immune micro-environment of breast cancer (BC) seriously affects the clinical outcome. This study aims to explore the role of tumor immune genes in the prognosis of BC patients and construct an immune-related genes prognostic index. Methods The list of 2498 immune genes was obtained from ImmPort database. In addition, gene expression data and clinical characteristics data of BC patients were also obtained from the TCGA database. The prognostic correlation of the differential genes was analyzed through Survival package. Cox regression analysis was performed to analyze the prognostic effect of immune genes. According to the regression coefficients of prognostic immune genes in regression analysis, an immune risk scores model was established. Gene set enrichment analysis (GSEA) was performed to probe the biological correlation of immune gene scores. P < 0.05 was considered to be statistically significant. Results In total, 556 immune genes were differentially expressed between normal tissues and BC tissues (p < 0. 05). According to the univariate cox regression analysis, a total of 66 immune genes were statistically significant for survival risk, of which 30 were associated with overall survival (P < 0.05). Finally, a 15 immune genes risk scores model was established. All patients were divided into high- and low-groups. KM survival analysis revealed that high immune risk scores represented worse survival (p < 0.001). ROC curve indicated that the immune genes risk scores model had a good reliability in predicting prognosis (5-year OS, AUC = 0.752). The established risk model showed splendid AUC value in the validation dataset (3-year over survival (OS) AUC = 0.685, 5-year OS AUC = 0.717, P = 0.00048). Moreover, the immune risk signature was proved to be an independent prognostic factor for BC patients. Finally, it was found that 15 immune genes and risk scores had significant clinical correlations, and were involved in a variety of carcinogenic pathways. Conclusion In conclusion, our study provides a new perspective for the expression of immune genes in BC. The constructed model has potential value for the prognostic prediction of BC patients and may provide some references for the clinical precision immunotherapy of patients.

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

Abstract Background The neutrophil–lymphocyte ratio (NLR), a presumed measure of the balance between neutrophil-associated pro-tumour inflammation and lymphocyte-dependent antitumour immune function, has been suggested as a prognostic factor for several cancers, including hepatocellular carcinoma (HCC). Methods In this study, a prospectively accrued cohort of 781 patients (493 HCC and 288 chronic liver disease (CLD) without HCC) were followed-up for more than 6 years. NLR levels between HCC and CLD patients were compared, and the effect of baseline NLR on overall survival amongst HCC patients was assessed via multivariable Cox regression analysis. Results On entry into the study (‘baseline’), there was no clinically significant difference in the NLR values between CLD and HCC patients. Amongst HCC patients, NLR levels closest to last visit/death were significantly higher compared to baseline. Multivariable Cox regression analysis showed that NLR was an independent prognostic factor, even after adjustment for the HCC stage. Conclusion NLR is a significant independent factor influencing survival in HCC patients, hence offering an additional dimension in prognostic models.
