Abstract
BACKGROUND The prognostic performance of soluble CD40L (sCD40L) for illness severity in infectious diseases is rarely reported. We investigated the ability of sCD40L combined with Acute Physiology and Chronic Health Evaluation II (APACHE II) score to evaluate mortality in septic patients in the emergency department(ED). METHODS We enrolled 222 septic patients in the ED of Beijing Chao-Yang Hospital from October 2020 to April 2021. Their serum sCD40L, PCT, lactate (Lac), Sequential Organ Failure Assessment (SOFA) score, Acute Physiology and Chronic Health Evaluation II (APACHE II) score were used to predict the prognosis of septic patients in terms of 28-day mortality. Serum sCD40L was detected by Human XL Cytokine Luminex. Logistic regression analysis and receiver operating characteristic (ROC) curves were used to assess the prognostic value of the variables. RESULTS One hundred ninety-five patients met the inclusion criteria, divided into survival group (55 cases) and non-survival group (140 cases). sCD40L, PCT, Lac, SOFA and APACHE II score were found to independently predict 28-day mortality (P < 0.05). The AUC values of sCD40L, PCT, Lac, SOFA and APACHE II score were 0.662,0.727,0.704, 0.719 and 0.716, respectively. There was no difference in the diagnostic value of sCD40L compared with the PCT, Lac, SOFA score or APACHE II score (Z1 = 1.19, P = 0.234; Z2 = 0.77, P = 0.441; Z3 = 1.05, P = 0.294; Z4 = 0.97, P = 0.332). However, the combined evaluation of sCD40L + APACHE II (AUC:0.772, Z = 2.10, P = 0.036) was much better than sCD40L alone in predicting 28-day mortality. CONCLUSION The predictive value of sCD40L + APACHE II is better than sCD40L alone for 28-day mortality. sCD40L combined with APACHE II score is valuable for predicting 28-day mortality in elderly patients with sepsis.

Abstract
Although elevated serum levels of soluble CD40 ligand (sCD40L) were reported in patients with cancer, the importance of high sCD40L levels in clinical oncology remains unknown. We conducted a post hoc analysis of the AMATERASU randomized clinical trial of vitamin D3 supplementation (2000 IU/day) in patients with digestive tract cancer to assess its significance. Serum sCD40L levels were measured by ELISA in 294 residual samples, and were divided into tertiles. In patients with colorectal cancer (CRC), 5-year relapse-free survival (RFS) rates in the middle and highest tertiles were 61.6% and 61.2%, respectively, which was significantly lower than 83.8% in the lowest tertile. A Cox proportional hazard analysis showed that the lowest tertile had a significantly lower risk of relapse or death than the highest tertile even with multivariate adjustment (hazard ratio (HR), 0.30; 95% confidence interval (CI), 0.11-0.80; p = 0.016). In the subgroup of CRC patients with the highest tertile of sCD40L, the 5-year RFS rate in the vitamin D group was 77.9%, which was significantly higher than 33.2% in the placebo group (HR, 0.30; 95% CI, 0.11-0.81; p = 0.018 [Pinteraction = 0.04]). In conclusion, elevated sCD40L might be a biomarker of poor prognosis in patients with CRC, but vitamin D supplementation might improve RFS in patients with high sCD40L.

Abstract
AIM To evaluate the detection rate of subclinical carotid atherosclerosis in rheumatoid arthritis (RA) patients with low cardiovascular risk (CVR). MATERIALS AND METHODS The study included 182 RA patients with low CVR (mSCORE<1%) and no established cardiovascular diseases and a control group comprising 100 people. Atherosclerotic lesion of the carotid arteries was assessed using Doppler ultrasound of the carotid arteries and was determined by the detection of atherosclerotic plaque (ASP) - the local increase in the thickness of the intima-media complex (IMT) >1.5 mm. RESULTS Carotid ASP were observed more frequently in RA patients with low CVR than in the control group (17% versus 8%; p=0.02). The frequency of ASP in RA patients with low CVR did not depend on the disease's stage or activity and ongoing therapy. In RA, the detection of subclinical atherosclerosis was associated with traditional risk factors: carotid ASP were detected 4 times more often in men than in women (48% versus 12%, p<0.01); carotid IMT correlated with age (R=0.46), body mass index (R=0.17), LDL-C level (R=0.20), systolic blood pressure (R=0.17); p<0.05 in all cases. According to a multivariate model, in RA, the risk of developing ASP increased in the presence of dyslipidemia (odds ratio - OR 2.97; 95% confidence interval - CI 1.36-6.49; p=0.006) and arterial hypertension (OR 2.16; 95% CI 1.03-4.54; p=0.04). In RA patients with carotid ASP, sCD40L level was associated with carotid IMT (R=0.32; p=0.04) and cholesterol concentration (R=0.39; p=0.01). CONCLUSION Subclinical atherosclerotic lesions of the carotid arteries were observed in 24% of RA patients with low cardiovascular risk and were detected almost 2 times more often than in the control group. In RA patients with low CVR, the risk of developing carotid ASP increased by 2-3 times with concomitant hypertension and dyslipidemia. The carotid IMT was associated with traditional risk factors - age, gender, lipid levels and blood pressure indicators, in cases of detection of ASP - with an immunoinflammatory marker - sCD40L.

Abstract
Backgrounds It remained unclear whether isolated positive thyroid peroxidative antibodies (TPOAb) were associated with adverse maternal and neonatal outcomes. The purpose of this study was to observe adverse neonatal outcomes among euthyroid pregnant women with positive TPOAb and to investigate the underlying risk factors. Methods Euthyroid pregnant women with TPOAb positivity were enrolled and followed up in our study. Adverse neonatal outcomes such as preterm birth, low birth weight, and fetal macrosomia were observed. Clinical data in the first trimester were collected and compared between groups with or without adverse neonatal outcomes. Maternal serum soluble CD40 ligand (sCD40L) was also measured at the same time. Results A total of 176 euthyroid pregnant women with TPOAb positivity were finally enrolled and analyzed in our study. Thirty-nine (22.16%) euthyroid women with TPOAb positivity were found to have adverse neonatal outcomes. Thirteen participants received assisted reproductive technology (ART) in our study, and seven participants were in the adverse neonatal outcome group. Preterm birth, low birth weight, and fetal macrosomia were the most common comorbidities. The proportion of receiving ART and the levels of sCD40L and platelet were significantly higher in the adverse neonatal outcome group (all P < 0.05). Multivariate regression analysis showed that sCD40L and receiving ART were the independent risk factors for adverse neonatal outcomes. The odds ratio values of sCD40L higher than 5.625 ng/ml were 2.386 [95% confidence interval (CI) = 1.017 to 5.595; P = 0.046] for overall adverse neonatal outcome, 3.900 (95% CI = 1.194 to 12.738; P = 0.024) for preterm birth, and 3.149 (95% CI = 0.982 to 10.101; P = 0.054) for low birth weight. Conclusions Approximately one of the four euthyroid women with TPOAb positivity might have adverse neonatal outcomes. Measurement of sCD40L in first trimester might have a predictive value for adverse neonatal outcomes in euthyroid pregnant women with positive TPOAb.

Abstract
OBJECTIVE To evaluate the rate of subclinical carotid atherosclerosis and clinical significance of immunoinflammatory markers in patients with rheumatoid arthritis (RA) at low cardiovascular risk. MATERIALS AND METHODS The study included 275 RA patients and a control group of 100 participants without autoimmune diseases. All study participants were at low cardiovascular risk, calculated by the QRISK3 scale (<20%), and free of cardiovascular disease. Ultrasound examination of carotid arteries was performed to measure cIMT and to detect atherosclerotic plaques (ASP) in carotid arteries. sIСАМ-1, sVСАМ, and sCD40L levels were determined by enzyme immunoassay. RESULTS Carotid ASP was observed more frequently in RA patients (27%) than in the control group (17%), p = 0.03. The frequency of ASP in RA patients did not depend on the disease's stage or activity. There was a significant correlation between cIMT and age, cardiovascular risk determined by QRISK3, level of total cholesterol, LDL, and blood pressure in RA patients, p < 0.05 in all cases. No correlation between cIMT and blood levels of sCD40L, sVCAM, and sICAM was found. In RA patients, a higher concentration of sVCAM was detected in the carotid ASP group compared to the non-atherosclerotic group. sCD40L was associated with cIMT and total cholesterol in the ASP group and with total cholesterol and blood pressure in non-atherosclerotic patients. CONCLUSIONS Subclinical atherosclerotic lesions of the carotid arteries were observed significantly more frequently in RA patients with low cardiovascular risk than in the control group. The results of the study demonstrate the association between cIMT, traditional cardiovascular risk factors, and immunoinflammatory markers in RA patients.

Abstract
BACKGROUND IgA nephropathy (IgAN) is a major cause of chronic glomerulonephritis worldwide. T cell dysregulation has been reported to contribute to the pathogenesis of IgAN. Methods We measured a broad range of Th1, Th2 and Th17 cytokines in the serum of IgAN patients. We searched for significant cytokines, which were associated with clinical parameters and histological scores in IgAN patients. RESULTS Among 15 cytokines, the levels of soluble CD40L (sCD40L) and IL-31 were higher in IgAN patients and were significantly associated with a higher estimated glomerular filtration rate (eGFR), a lower urinary protein to creatinine ratio (UPCR), and milder tubulointerstitial lesions (i.e., the early phase of IgAN). Multivariate analysis revealed that serum sCD40L was an independent determinant of a lower UPCR after adjustment for age, eGFR, and mean blood pressure (MBP). CD40, a receptor of sCD40L, has been reported to be upregulated on mesangial cells in IgAN. The sCD40L/CD40 interaction may directly induce inflammation in mesangial areas and may therefore be involved in the development of IgAN. CONCLUSIONS The present study demonstrated the significance of serum sCD40L and IL-31 in the early phase of IgAN. Serum sCD40L may be a marker of the beginning of inflammation in IgAN.

Abstract
Introduction People living with HIV (PLWH) are at twice the risk of developing cardiovascular diseases and have more than four times higher odds of aortic aneurysm (AA) than the uninfected population. However, biomarkers of AA in PLWH are yet to be discovered. We aimed to investigate whether circulating biomarkers reflecting platelet activation, hemostasis and endothelial disruption, i.e. sCD40L, D-dimer, syndecan-1, and thrombomodulin, were associated with AA in PLWH. Methods Five hundred seventy one PLWH from the Copenhagen Comorbidity in HIV Infection (COCOMO) study ≥40 years of age with an available contrast-enhanced CT scan as well as available biomarker analyses were included. The biomarkers were analyzed on thawed plasma. For each biomarker, we defined high level as a concentration in the upper quartile and low level as a concentration below the upper quartile. For D-dimer, the cut-off was defined as the lower limit of detection. Using unadjusted and adjusted logistic and linear regression models, we analyzed associations between AA and sCD40L, D-dimer, syndecan-1, and thrombomodulin, respectively in PLWH. Results PLWH had median (IQR) age 52 years (47-60), 88% were male, median (IQR) time since HIV diagnosis was 15 years (8-23), and 565 (99%) were currently on antiretroviral treatment. High level of sCD40L was associated with lower odds of AA in both unadjusted (odds ratio, OR, 0.23 (95% CI 0.07-0.77; P=0.017)) and adjusted models (adjusted OR, aOR, 0.23 (95% CI 0.07-0.78; P=0.019)). Detectable level of D-dimer was associated with higher odds of AA in both unadjusted (OR 2.76 (95% CI 1.34-5.67; P=0.006)) and adjusted models (aOR 2.22 (95% CI 1.02-4.85; P=0.045)). Conclusions SCD40L was associated with lower odds of AA whereas D-dimer was independently associated with higher odds of AA in PLWH. This calls for further investigations into specific biomarkers to aid early diagnosis of AA in PLWH.

Abstract
Regular physical exercise was found to be associated with an improved immune response in previous studies. RANTES and CD40L play a pivotal role in host defense, and individuals lacking adequate expression are prone to virus and opportunistic infections. A total of 98 participants were enrolled in this study. The probands were asked to perform moderate physical activity, and bicycle stress tests were performed at the baseline and after 8 months of training to evaluate individual performance. RANTES and CD40L were found to be increased by long-term physical exercise. In particular, probands with a performance gain of ≥3% displayed a pronounced elevation of both markers, paired with a decrease in circulating IL6 levels and an improved lipid profile. In summary, we were able to highlight rising levels of serum RANTES and CD40L under the conditions of physical exercise. Taking their role in host defense into account, a conjunction of physical activity and the adaptive immune system could therefore be assumed. Furthermore, low inflammatory profiles in probands with a significant performance gain suggest a modulation through exercise rather than a generalized pro-inflammatory status.

Abstract
High-density lipoproteins (HDL) play an important role in the prevention of atherosclerosis. The aim of the study was to assess the relationship between serum HDL-C concentration and proinflammatory/prothrombic activation in coronary artery disease (CAD) patients. The study group included 27 acute myocardial infarction (AMI) patients and 30 stable angina pectoris (SA) patients. The control group consisted of 23 people without cardiac symptoms. In the AMI and SA groups, a lower HDL-C and a higher LDL-C/HDL-C index were observed. The SA patients had lower total cholesterol, LDL-C, sE-selectin ligand, as well as higher triglycerides and CD40 concentration in comparison with both the control and AMI groups. A higher von Willebrand Factor and intercellular adhesion molecule-1 were found in both study groups. Low HDL-C concentration in the CAD patients may intensify pro-inflammatory endothelial activation and prothrombotic processes. A low concentration of HDL-C and a high value of the LDL-C/HDL-C index seem to be better indices of atherogenic processes than the LDL-C concentration alone.

Abstract
Multiple sclerosis (MS) is a debilitating autoimmune disorder. Currently, there is a lack of effective treatment for the progressive form of MS, partly due to insensitive readout for neurodegeneration. The recent development of sensitive assays for neurofilament light chain (NfL) has made it a potential new biomarker in predicting MS disease activity and progression, providing an additional readout in clinical trials. However, NfL is elevated in other neurodegenerative disorders besides MS, and, furthermore, it is also confounded by age, body mass index (BMI), and blood volume. Additionally, there is considerable overlap in the range of serum NfL (sNfL) levels compared to healthy controls. These confounders demonstrate the limitations of using solely NfL as a marker to monitor disease activity in MS patients. Other blood and cerebrospinal fluid (CSF) biomarkers of axonal damage, neuronal damage, glial dysfunction, demyelination, and inflammation have been studied as actionable biomarkers for MS and have provided insight into the pathology underlying the disease process of MS. However, these other biomarkers may be plagued with similar issues as NfL. Using biomarkers of a bioinformatic approach that includes cellular studies, micro-RNAs (miRNAs), extracellular vesicles (EVs), metabolomics, metabolites and the microbiome may prove to be useful in developing a more comprehensive panel that addresses the limitations of using a single biomarker. Therefore, more research with recent technological and statistical approaches is needed to identify novel and useful diagnostic and prognostic biomarker tools in MS.

Abstract
The incidence of non-Hodgkin's lymphoma (NHL) has been increasing annually and has become a serious threat to human health. However, the pathogenesis of NHL remains unclear. The present study aimed to investigate the effect of soluble CD40 ligand (sCD40L) on NHL cells and its underlying mechanism. Cell Counting kit-8 assay and flow cytometry apoptosis experiments were conducted to investigate the effects of sCD40L on cell proliferation and apoptosis. Western blotting was performed to detect the protein expression levels of BAX, Bcl-2, ERK, p-ERK, JNK, p-JNK, p38, p-p38 and c-JUN. The results of the present study demonstrated that exogenous sCD40L significantly inhibited the proliferation and promoted the apoptosis of Raji and CA46 cells. Additionally, exogenous sCD40L promoted the apoptosis of lymphoma cells by activating the JNK signaling pathway.

Abstract
INTRODUCTION Multiple Sclerosis (MS) is a chronic, autoimmune, demyelinating disease of the central nervous system (CNS). Currently, several protocols are described for the different phases of MS. In this longitudinal study, we aim to quantify the concentration of plasma cytokines of MS patients treated with Fingolimod alone or after Glatiramer Acetate (GA) or Interferon-beta (IFN-β), in order to compeer both treatments and describes if it is possible to use them as biomarkers. OBJECTIVE Compare the two different types of drug treatment and describes possible immune biomarkers in RRMS patients treated with Fingolimod alone or after GA or IFN-β. MATERIALS AND METHODS This is a controlled, non-randomized clinical trial. Plasma concentrations of IL-31, sCD40L and nine others cytokines were evaluated in two groups of patients with a one-year follow-up. Group 1 (n = 12): RRMS patients treated with GA or IFN-β for at least six months before the study who changed therapy to Fingolimod after six months, and Group 2 (n = 12): naïve RRMS patients who started treatment with Fingolimod. We used ANOVA two-way to analyze the cytokines and Spearman coefficient to evaluate the correlation. RESULTS Although Group 2 started with a greater number of relapses per disease duration, Fingolimod treatment was effective in decreasing this parameter, as well as EDSS over 12 months. However, the treatment with GA or IFN-β on Group 1 showed a tendency to increase the number of relapses after 6 months of follow-up, which decrease when the therapy was changed to Fingolimod. After the evaluation of 11 cytokines in one year, we found that IL-31 and sCD40L were the biomarkers that demonstrated a more difference when compared to the classical ones, following the clinical pattern over the treatment period. CONCLUSIONS Our study describes the existence of two promising plasmatic biomarkers (IL-31 and sCD40L), which reduced plasmatic levels in RRMS patients followed the treatment time of Fingolimod, despite that more studies are needed to prove their efficiency.

Abstract
Backgroud and purpose: Soluble CD40 ligand (sCD40L) plays an important role in inflammation and autoimmune disorders. There is still a controversy regarding sCD40L in neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS). Herein the aims of this study were to evaluate the levels of sCD40L in patients with NMOSD, MS, and other noninflammatory neurological diseases; to investigate its potential relationship with laboratory parameters, glial fibrillary acidic protein (GFAP), thrombopoietin (TPO) and IL-6; and to address whether serum sCD40L levels in acute attacks of NMOSD patients were decreased after treatment with immunoglobulins, plasma exchange, or methylprednisolone.Materials and methods: We enrolled 13 patients with NMOSD, 9 patients with MS, and 9 patients with other noninflammatory neurological diseases. The levels of sCD40L, IL-6 were measured by cytokine multiplex assay. GFAP levels were measured by ELISA.Results: Both serum and cerebrospinal fluid (CSF) sCD40L levels were increased in NMOSD and MS. No differences were found in serum and CSF sCD40L levels between NMOSD and MS. The CSF sCD40L levels were positively correlated with the CSF cell counts in NMOSD, whereas serum sCD40L levels were positively correlated with the albumin index in MS. Furthermore, the levels of CSF sCD40L were positively correlated with CSF GFAP levels in NMOSD. Serum sCD40L levels were correlated with serum TPO levels in MS. No correlation was found between levels of sCD40L and IL-6 in NMOSD and MS. No statistically meaningful difference between NMOSD patients with or without immunotherapy. Conclusions: Our study suggests that sCD40L can contribute to the destruction of the blood-brain barrier in MS, whereas it may contribute to CNS inflammation in NMOSD. The serum sCD40L concentrations were not changed after treatment with immunoglobulins, plasma exchange, or methylprednisolone in acute attacks of NMOSD.

Abstract
BACKGROUND AND OBJECTIVES Transfusion-related acute lung injury (TRALI) is a life-threatening complication of transfusion and is one of leading causes of transfusion-associated fatalities. However, the pathogenesis of TRALI is still unclear. Soluble CD40 ligand (sCD40L) is a proinflammatory cytokine that accumulates during blood component storage and is involved in transfusion reactions. The objective of this study was to establish a clinically relevant TRALI animal model and to evaluate the role of sCD40L in TRALI. MATERIALS AND METHODS Rats' red-blood-cell (RBC) suspensions were prepared, and the quality of RBC was evaluated. A trauma-haemorrhage-transfusion strategy was applied to build the animal model. Lung oedema was evaluated by histopathology examination, total bronchoalveolar lavage fluid (BALF) protein concentration, Evans blue dye (EBD) leakage and inflammatory cytokines. The sCD40L concentrations were measured. RESULTS Storage lesions of RBCs gradually increased over time. Obvious histological evidence of lung injury of rats transfused with a 35-day RBC was observed. The total BALF protein concentration, EBD leakage, inflammatory cytokines concentration were increased significantly in the Day 35 group. The sCD40L concentration increased significantly in the storage RBC suspension over time but was slightly elevated in rat plasma. CONCLUSIONS These findings indicated successful establishment of a TRALI animal model with trauma-haemorrhage-transfusion, in which sCD40L may play a minor role in the development of TRALI.

Abstract
BACKGROUND Higher circulating soluble cluster of differentiation 40 ligand (sCD40L) levels at admission of an ischemic stroke have been found in nonsurvivor than in survivor patients. The objectives of this study were to determine whether serum sCD40L levels during the first week of a severe malignant middle cerebral artery infarction (MMCAI) are higher in nonsurvivor than in survivor patients and whether they could be used as biomarker of mortality prediction. METHODS This multicenter study included patients with severe MMCAI (defined as Glasgow Coma Scale score <9). We determined serum sCD40L concentrations at days 1, 4, and 8 and performed receiver operating characteristic analyses to determine their capacity for 30-day mortality prediction. RESULTS Nonsurvivors (n = 34) showed higher sCD40L levels on days 1 (P < 0.001), 4 (P = 0.004), and 8 (P < 0.001) than did survivor patients (n = 34). Areas under the curve of serum sCD40L concentrations at days 1, 4, and 8 of severe MMCAI for 30-day mortality prediction were 83% (P < 0.001), 89% (P < 0.001), and 87% (P < 0.001), respectively. CONCLUSIONS The findings that nonsurvivors showed higher serum sCD40L levels during the first week of MMCAI than did survivors and that serum sCD40L levels during the first week of MMCAI could be used as a mortality predictor biomarker are 2 novel findings.

Abstract
Background and objectives: No-reflow (NR) phenomenon is defined as insufficient myocardial perfusion in coronary circulation in the absence of angiographic evidence of mechanical obstruction. The primary mechanisms of the NR occurrence are thought to be high platelet activity and thrombus burden. Soluble CD40 ligand (sCD40L), which is released into the plasma following platelet activation, accelerates the inflammatory process and causes further platelet activation. The aim of our study is to investigate the relationship between the NR phenomenon and sCD40L level in patients with ST-elevation myocardial infarction (STEMI). Methods: A total of 81 acute STEMI patients undergoing primary percutaneous coronary intervention and 40 healthy participants were included in this study. Acute STEMI patients were classified into two groups: 41 patients with the NR phenomenon (NR group) and 40 patients without the NR phenomenon (non-NR group). The serum sCD40L level was measured for all groups. Results: The serum sCD40L level was significantly higher in the NR group than in non-NR and control groups (379 ± 20 pg/mL, 200 ± 15 pg/mL and 108 ± 6.53 pg/mL, respectively; p < 0.001). Univariate regression analysis demonstrated that male sex, age, Gensini score and sCD40L level were the possible factors affecting the occurrence of the NR phenomenon. In multivariate regression analysis, age (odds ratio [OR], 1.091; 95% confidence interval [CI], 1.023–1.163; p < 0.008) and serum sCD40L (OR, 1.016; 95% CI, 1.008–1.024; p < 0.001) remained the independent predictor of the presence of NR. Conclusions: Our study showed that serum sCD40L level was an independent predictor of the NR phenomenon occurrence.

Abstract
BACKGROUND Soluble cluster of differentiation 40 ligand (sCD40L) is a member of the tumor necrosis factor family with proinflamatory and procoagulant effects. A previous study found higher serum sCD40L levels at day 1 of traumatic brain injury (TBI) in nonsurviving than surviving patients. Thus the objective of this study was to compare serum sCD40L levels during the first week of a severe TBI between surviving and nonsurviving patients and to determine whether it could be used as a mortality predictor biomarker. METHODS In this multicenter study severe TBI patients (with Glasgow Coma Scale score <9) with an Injury Severity Score in noncranial item <9 were included. Serum sCD40L concentrations at days 1, 4, and 8 of TBI were determined. We performed receiver operating characteristic analyses to determine the capacity of 30-day TBI mortality prediction by serum sCD40L levels at days 1, 4, and 8 of TBI. RESULTS We found that nonsurviving (n = 34) patients in comparison with surviving (n = 90) patients had higher sCD40L levels on days 1 (P < 0.001), 4 (P = 0.004), and 8 (P < 0.001) of TBI. We also found that the areas under curve of serum sCD40L concentrations at days 1, 4, and 8 of TBI to 30-day mortality prediction were 82% (P < 0.001), 72% (P = 0.01) and 83% (P < 0.001), respectively. CONCLUSIONS The existence of higher serum sCD40L levels in nonsurviving than surviving patients during the first week of TBI and fact that serum sCD40L levels during the first week of TBI can be used as a mortality predictor biomarker are the new findings of our study.

Abstract
Human Immunodeficiency Virus (HIV) co-infection drastically increases the risk of developing overt visceral leishmaniasis (VL). The asymptomatic Leishmania infection window constitutes an opportunity to identify those HIV patients at highest risk by defining early markers associated with disease susceptibility or resistance. As intracellular parasite killing is essential, we investigated whether serum markers of macrophage activation were notably affected in HIV patients with an asymptomatic Leishmania infection or overt visceral leishmaniasis disease. Serum levels of soluble CD40 ligand and neopterin were assessed in 24 active VL-HIV patients, 35 HIV patients with asymptomatic Leishmania infection and 35 HIV endemic controls. All patients were recruited in L. donovani endemic regions of North-West Ethiopia. The serum levels of sCD40L and neopterin significantly decreased and increased in HIV patients with active VL compared to HIV patients with asymptomatic Leishmania infection, respectively. No statistically significant differences could be detected in neopterin and sCD40L levels between Leishmania asymptomatically infected HIV patients and endemic HIV control patients. However, an inverse trend, between Leishmania antibody positivity or VL development and neopterin levels could be seen. The CD4+ T-cell count was inversely correlated with serum neopterin levels, but not with sCD40L levels. Our results in HIV coinfected patients, correspond with the postulated protective role of sCD40L in VL and underline the importance of the CD40-CD40L pathway in resistance against the parasite. Neopterin levels suggest an increased macrophage activation upon infection and could have a value in clinical algorithms to, although non-specifically, improve prediction of VL development in HIV patients with asymptomatic Leishmania infection.

Abstract
BACKGROUND The role of CD40/CD40L in carcinogenesis is widely examined. The mechanisms linking the CD40/CD40L system and the soluble form of CD40 ligand (sCD40L) with neoplasia are nowadays a topic of intensive research. CD40L and sCD40L belong to the TNF superfamily and are molecules with a proinflammatory role. A variety of cells express CD40L such as the immune system cells, the endothelial cells and activated platelets. Although many medications such as statins have been shown to reduce sCD40L, it is still debated whether specific treatments targeting the CD40/CD40L system will prove to be effective against carcinogenesis in the near future. MATERIALS AND METHODS A comprehensive search of the Pubmed Database was conducted for English-language studies using a list of key words. RESULTS At diagnosis, serum samples of patients with neoplasia contained higher levels of sCD40L than healthy controls, suggesting that sCD40L may play a predictive role in human carcinogenesis. CONCLUSION Patients with neoplasia had higher circulating sCD40L levels and it is likely that sCD40L may have a predictive role. It is still unclear whether sCD40L can be used as a therapeutic target.

Abstract
Background Studies have suggested that soluble factors in plasma from patients with active (aBD) and inactive (iBD) Behçet’s disease (BD) stimulate neutrophil function. Soluble CD40 ligand (sCD40L) is an important mediator of inflammation in BD. Its expression and effect on neutrophil oxidative burst and neutrophil extracellular trap (NET) release have not been characterized. In this study, we sought to investigate the role of plasma and the CD40L pathway on NET release and the oxidative burst profile in patients with aBD and iBD. Methods Neutrophils and peripheral blood mononuclear cells (PBMCs) were obtained from patients with aBD (n = 30), patients with iBD (n = 31), and healthy control subjects (HCs; n = 30). sCD40L plasma concentration was determined in individual samples. A pool of plasma for each group was created. In some experiments, plasma pools were treated with recombinant CD40 (rhCD40-muIg) for sCD40L blockade. NET release and H2O2/O2− production were determined after stimulation with phorbol 12-myristate 13-acetate, sCD40L, or plasma pool. Flow cytometric analysis was performed to evaluate the expression of (1) CD40, Mac-1, and phosphorylated NF-κB p65 on neutrophils and monocytes and (2) CD40L on activated T cells and platelets. CD40L gene expression in PBMCs was determined by qRT-PCR. Results sCD40L plasma levels were significantly higher in patients with iBD (median 17,234, range 2346–19,279 pg/ml) and patients with aBD (median 18,289, range 413–19,883 pg/ml) than in HCs (median 47.5, range 33.7–26.7 pg/ml; p < 0.001). NET release was constitutively increased in BD compared with HC. NET release and H2O2/O2− were higher after stimulation with sCD40L or BD plasma and decreased after sCD40L blockade. Mac-1 expression was constitutively increased in neutrophils of patients with aBD (88.7 ± 13.2% of cells) and patients with iBD (89.2 ± 20.1% of cells) compared with HC (27.1 ± 18.8% of cells; p < 0.01). CD40 expression on phagocytes and CD40L expression on platelets were similar in the three groups. PBMCs as well as nonactivated and activated CD4+ T cells from patients with BD showed higher CD40L expression. Conclusions Plasma from patients with aBD exerts a stimulus on NET release and oxidative burst, probably induced by sCD40L.

Abstract
BACKGROUND Several patients encompass a scarce weight loss after Roux-en-Y gastric bypass (RYGB). As such event is not related to surgical complications, finding markers able to identify "well responders" and to predict weight loss outcome is clinically relevant. Ghrelin regulates appetite and energy balance. Common single nucleotide polymorphisms (SNPs) in its encoding genes have been associated with body weight regulation. Other peptides involved in satiety modulation, like the CD40/CD40L complex, are less explored. METHODS One hundred, otherwise healthy, obese subjects (aged 45 ± 11 years, 65 females, BMI 48.0 ± 0.7 kg/m2) were sequentially enrolled in years 2014-2015. SNPs rs2241766 for adiponectin gene, rs490683 for ghrelin receptor, rs696217 and rs27647 for the preproghrelin/ghrelin gene, and rs1126535 for the CD40L gene were determined on DNA extracted from circulating lymphomonocytes. Patients were reevaluated at 6 (n = 100), 26 (n = 91), and 52 weeks (n = 79) after RYGB. RESULTS Subjects carrying the rs696217 T allele encompassed a significantly greater reduction in BMI 52 weeks after surgery (GG vs GT 30.5 ± 1.1 vs 38.1 ± 2.1 %; p < 0.001). Carrying the rs1126535 C allele in the CD40L gene was associated with a significantly lower BMI reduction at week 52 (TT vs CT 33.2 ± 1.1 vs 28.1 ± 2.3 %, p = 0.049). rs490683 and rs27647 SNPs of ghrelin and rs2241766 for adiponectin gene did not show any difference between carriers and non-carriers of the mutant allele. CONCLUSION Carrying a G to T substitution in rs696217 (preproghrelin gene) seems to mark a successful weight loss outcome; we also report for the first time that the rs1126535 C allele (CD40L gene) may predict a worse response to bariatric surgery.

Abstract
INTRODUCTION Soluble CD40 ligand (sCD40L) is a protein with proinflammatory and prothrombotic effects. Previously we found higher circulating sCD40L levels in non-survivor than in survivor patients at sepsis diagnosis. Now some questions arise such as how are serum sCD40L levels during the first week of severe sepsis?, is there an association between serum sCD40L levels during the first week and mortality?, and serum sCD40L levels during the first week could be used as sepsis mortality biomarker?. This study was developed to answer these asks. METHODS Study from 6 Spanish Intensive Care Units with 291 severe septic patients. There were determined serum levels of sCD40L and tumor necrosis factor (TNF)-alpha during the first week. The end-point study was 30-day mortality. RESULTS We found that serum sCD40L at days 1, 4, and 8 could predict mortality at 30days, and are associated with mortality. CONCLUSIONS The novel findings of our study were that there were higher serum sCD40L levels persistently during the first week in non-survivor than in survivor patients, that there is an association between serum sCD40L levels during the first week and sepsis mortality, and that serum sCD40L levels during the first week could be used as sepsis mortality biomarker.

Abstract
AIM Soluble CD40 ligand (sCD40L) has been considered as a marker of thrombosis and inflammation in several diseases, including sepsis. Recent studies challenge this view and point to a role of sCD40L in vascular and endothelial function. An indication of that association in sepsis has not been obtained so far. Therefore, herein we evaluated association between sCD40L and markers of hemorheology and inflammation on context of septic shock. METHODS Time-changes of sCD40L levels over 72 hours of Intensive Care Unit (ICU) internment were assessed in 22 patients with septic shock and compared with 36 healthy volunteers. Association of sCD40L levels with erythrocyte deformability and aggregation (as markers of hemorheology), plasma concentrations of haemoglobin (Hb, as markers of endothelial function) and white blood cells (WBC) count (as marker of low-grade inflammation) were assessed in patients with septic shock. RESULTS At ICU admission, sCD40L concentrations in patients with septic shock were lower (p = 0.024) than levels of healthy volunteers. However, sCD40L did not change over 72 hours of internment (F = 2.1, p = 0.137). Soluble CD40L levels in patients with septic shock at ICU admission correlate with concentrations of Hb (r = 0.61, p = 0.00) and WBC count (r = 0.63, p = 0.00), but not to erythrocyte deformability (r≥0.157, p≤0.235) and aggregation (r≥-0.109, p≤0.192). CONCLUSIONS These results seem to highlight a possible association of sCD40L to endothelial function and inflammation in septic shock context.

Abstract
Background The role of pathogen specific cellular immune responses against the eliciting pathogen in development of post-infectious chronic fatigue syndrome (PI-CFS) is not known and such studies are difficult to perform. The aim of this study was to evaluate specific anti-Giardia cellular immunity in cases that developed CFS after Giardia infection compared to cases that recovered well. Patients reporting chronic fatigue in a questionnaire study three years after a Giardia outbreak were clinically evaluated five years after the outbreak and grouped according to Fukuda criteria for CFS and idiopathic chronic fatigue. Giardia specific immune responses were evaluated in 39 of these patients by proliferation assay, T cell activation and cytokine release analysis. 20 Giardia exposed non-fatigued individuals and 10 healthy unexposed individuals were recruited as controls. Results Patients were clinically classified into CFS (n = 15), idiopathic chronic fatigue (n = 5), fatigue from other causes (n = 9) and recovered from fatigue (n = 10). There were statistically significant antigen specific differences between these Giardia exposed groups and unexposed controls. However, we did not find differences between the Giardia exposed fatigue classification groups with regard to CD4 T cell activation, proliferation or cytokine levels in 6 days cultured PBMCs. Interestingly, sCD40L was increased in patients with PI-CFS and other persons with fatigue after Giardia infection compared to the non-fatigued group, and correlated well with fatigue levels at the time of sampling. Conclusion Our data show antigen specific cellular immune responses in the groups previously exposed to Giardia and increased sCD40L in fatigued patients.

Abstract
OBJECTIVE To determine the prevalence of three single nucleotide polymorphisms (SNPs) in postmenopausal women with and without the metabolic syndrome (METS) and to explore levels of circulating biomarkers of inflammation, vascular and metabolic dysfunction according to SNP genotypes. METHODS DNA was extracted from the whole blood of 192 natural postmenopausal women (40 to 65 years) screened for the METS and tested for three gene SNPs related to obesity: the fat mass obesity (FTO: rs9939609) and the methylenetetrahydrofolate reductase (MTHFR: C677T and A1298C). Blood levels of angiopoietin, IL-8, sFASL, IL-6, TNF-α, sCD40L, PAI-1, u-PA, leptin, adiponectin, resistin, ghrelin, visfatin, adipsin and insulin were measured in a subgroup, with and without the METS, using multiplex technology (n = 100) and compared according to SNP genotypes. RESULTS Genotype frequency of the three studied SNPs did not differ in relation to the presence of the METS. However, genotypes CT+TT (C677T) and AT (rs9939609) were more prevalent in women with high triglyceride levels. Pooled sub-analysis (n = 100) found that median sCD40L and visfatin levels were higher in women with genotypes AT+TT (rs9939609) as compared to AA (1178 vs. 937.0 pg/mL and 0.93 vs. 0.43 ng/mL, respectively, p < 0.05). CONCLUSION Two SNP genotypes related to obesity were more prevalent in women with abnormal triglyceride levels and two vascular and inflammatory serum markers were higher in relation to the rs9939609 SNP.

Abstract
OBJECTIVE CD154 (CD40L) is a protein that is primarily expressed on activated T cells and is a member of the TNF superfamily of molecules. It binds to CD40 on antigen-presenting cells (APC), which leads to many effects depending on the target cell type. Being an activator of immune cells, CD40L has also been shown to directly induce apoptosis in tumor cells by multiple mechanisms. To understand the role of sCD40L in regulating the proliferation of epithelial ovarian cancer cells treated or untreated with cisplatin. METHODS Epithelial ovarian cancer cells: SKOV3 and its cisplatin-resistant strain SKOV3/DDP cells were used to test the effect of sCD40L and cisplatin. The proliferation of SKOV3 and SKOV3/DDP cells were measured by MTT. Cell cycle was assessed by flow cytometry. The mRNA expressions of targeted genes were detected by qRT-PCR. The protein expressions were detected by Western blotting. RESULTS sCD40L showed a significant dose-dependence inhibitory effect on the proliferation of ovarian cancer cell lines. sCD40L in combination with cisplatin could sensitized SKOV3/DDP cells to cisplatin treatment and reversed the drug resistance of SKOV3/DDP cells. The reversal ratios of 1 μg/ml sCD40L combined with cisplatin in SKOV3 and SKOV3/DDP cells were 2.11, 2.71, while the reversal ratios of 2 μg/ml sCD40L combined with cisplatin in SKOV3 and SKOV3/DDP cells were 3.78, 5.20, respectively. sCD40L or sCD40L combined cisplatin increased tumor cells in G0/G1 phase. sCD40L in combination with cisplatin decreased the expression levels of GST-π, LRP, Survivin, p53 and Bcl-2 in both epithelial ovarian cancer cell lines. The protein expression level of GST-π, LRP and P53 protein was also decreased upon sCD40L in combination with cisplatin although the expression level of Bcl-2 and survivin protein had no significant difference. CONCLUSION sCD40L inhibits the proliferation of SKOV3 and SKOV3/DDP cells. The combined application of sCD40L and cisplatin can strength the inhibitory effect of cisplatin, and to a certain extent, reversing the resistance to cisplatin in SKOV3/DDP cells. sCD40L could lead a cell block in G0/G1 phase and make the cell growth restrained. sCD40L could induce SKOV3 and SKOV3/DDP cells apoptosis and reverse drug resistance through cutting GST-π mRNA, LRP mRNA, survivin mRNA, p53 mRNA and Bcl-2 mRNA and decreasing the expression of GST-π, LRP and P53 protein in SKOV3 and SKOV3/DDP cells, which provides in-vivo experiment basis to the application of sCD40L as a drug improving ovarian cancer cells sensitivity to cisplatin.

Abstract
Context: Traumatic brain injury (TBI) is a leading cause of death, disability, and resource consumption per year. There are two kinds of brain injury in TBI, primary and secondary injuries. Primary injury refers to the initial physical forces applied to the brain at the moment of impact. Secondary injury occurs over a period of hours or days following the initial trauma and results from the activation of different pathways such as inflammation, coagulation, oxidation, and apoptosis. Evidence Acquisition: This review focuses on new prognostic biomarkers of mortality in TBI patients related to inflammation, coagulation, oxidation, and apoptosis. Results: Recently circulating levels of substance P (SP), soluble CD40 ligand (sCD40L), tissue inhibitor of matrix metalloproteinases (TIMP)-1, malondialdehyde (MDA), and cytokeratin (CK)-18 fragmented have been found to be associated with mortality in TBI patients. Substance P is a neuropeptide of the tachykinin family, mainly synthesized in the central and peripheral nervous system, with proinflammatory effects when binding to their neurokinin-1 receptor (NK1R). Soluble CD40 ligand, a member of the tumor necrosis factor (TNF) family that is released into circulation from activated platelets, exhibit proinflamatory, and procoagulant properties on binding to their cell surface receptor CD40. Matrix metalloproteinases (MMPs) are a family of zinc-containing endoproteinases involved neuroinflammation and TIMP-1 is the inhibitor of some of them. Malondialdehyde is an end-product formed during lipid peroxidation due to degradation of cellular membrane phospholipids, that is released into extracellular space and finally into the blood. Cytokeratin -18 is cleaved by the action of caspases during apoptosis, and CK-18 fragmented is released into the blood. Conclusions: Circulating levels of some biomarkers, such as SP, sCD40L, TIMP-1, MDA, and CK-18 fragmented, related to inflammation, coagulation, oxidation, and apoptosis have been recently associated with mortality in patients with TBI. These biomarkers could help in the prognostic classification of the patients and open new research lines in the treatment of patients with TBI.

Abstract
The purpose of this research was to investigate the mechanisms of antiplatelet action of Cyperus digitatus. The antiplatelet action of C. digitatus was studied on platelet function: secretion, adhesion, aggregation, and sCD40L release. The platelet ATP secretion and aggregation were significantly inhibited by CDA (ethyl acetate extract) at 0.1 mg/ml and after the incubation of whole blood with CDA, the platelet coverage was inhibited by 96 ± 3% (p < 0.001). At the same concentration, CDA significantly decreased sCD40L levels. The mechanism of antiplatelet action of CDA could be by NF-κB inhibition and that is cAMP independent. In conclusion, C. digitatus extract may serve as a new source of antiplatelet agents for food and nutraceutical applications.

Abstract
We have recently performed the first comprehensive study of the potential immunosuppressive role of soluble CD40L (sCD40L). In addition, we demonstrated that serum sCD40L can potentially be used as an indicator of response to anticancer therapy, and/or to better identify those patients who would have best chances to benefit from tumor-targeting vaccines or other therapeutic modalities.

Abstract
BACKGROUND Serum soluble CD40 Ligand (sCD40L) levels, which exhibit prothrombotic and proinflammatory properties, have not been studied in patients with traumatic brain injury (TBI). Thus, the objective of this study was to determine whether serum sCD40L levels are associated with severity and mortality in patients with severe TBI. METHODS This was a prospective, observational and multicenter study carried out in six Spanish Intensive Care Units. Patients with severe TBI defined as Glasgow Coma Scale (GCS) lower than 9 were included, while those with Injury Severity Score (ISS) in non-cranial aspects higher than 9 were excluded. Serum levels of sCD40L were measured on the day of TBI. Endpoint was established in 30-day mortality. RESULTS We found higher serum sCD40L levels (P<0.001) in non-surviving TBI patients (N=27) than in survivor ones (N=73). Logistic regression analysis showed that serum sCD40L levels were associated with 30-day mortality (OR=1.58; 95% CI=1.12-2.21; P=0.008) controlling for APACHE-II score and computer tomography findings. The area under the curve (AUC) for serum sCD40L levels as predictor of 30-day mortality was 0.79 (95% CI=0.70-0.86; P<0.001). Survival analysis showed that patients with serum sCD40L levels higher than 2.11 ng/mL presented increased 30-day mortality than patients with lower levels (Hazard ratio=9.0; 95% CI=4.25-19.27; P<0.001). We found an association between serum sCD40L levels and APACHE-II (rho=0.33; P=0.001), and GCS score (rho=-0.21; P=0.04). CONCLUSIONS To our knowledge, this is the first study reporting data on serum sCD40L levels in patients with severe TBI. The most relevant and newer findings of our study are that serum sCD40L levels in non-surviving patients with severe TBI are higher than in surviving ones, and that there are an association between serum sCD40L levels and TBI severity and mortality.

Abstract
Chronic lymphocytic leukemia (CLL) cells fail to enter apoptosis in vivo as opposed to their non-malignant B-lymphocyte counterparts. The ability of CLL cells to escape apoptosis is highly dependent on their microenvironment. Compared to non-malignant B cells, CLL cells are more responsive to complex stimuli that can be reproduced in vitro by the addition of cytokines. To understand the molecular mechanism of the environment-dependent anti-apoptotic signaling circuitry of CLL cells, we quantified the effect of the SDF-1, BAFF, APRIL, anti-IgM, interleukin-4 (IL4) and secreted CD40L (sCD40L) on the survival of in vitro cultured CLL cells and found IL4 and sCD40L to be most efficient in rescuing CLL cells from apoptosis. In quantitative dose-response experiments using cell survival as readout, the binding affinity of IL4 to its receptor was similar between malignant and non-malignant cells. However, the downstream signaling in terms of the amount of STAT6 and its degree of phosphorylation was highly stimulated in CLL cells. In contrast, the response to sCD40L showed a loss of cooperative binding in CLL cells but displayed a largely increased ligand binding affinity. Although a high-throughput microscopy analysis did not reveal a significant difference in the spatial CD40 receptor organization, the downstream signaling showed an enhanced activation of the NF-kB pathway in the malignant cells. Thus, we propose that the anti-apoptotic phenotype of CLL involves a sensitized response for IL4 dependent STAT6 phosphorylation, and an activation of NF-kB signaling due to an increased affinity of sCD40L to its receptor.

Abstract
Psoriasis is a systemic inflammatory disease of the skin with associated comorbidity. Severe forms of psoriasis are associated with increased mortality, which might be due to cardiovascular (CV) comorbidity. In this study, we investigated in 79 patients with psoriasis compared to 80 healthy volunteers different biomarkers that play a role in vascular disease and inflammation, such as C-reactive protein (CRP), human soluble CD40 ligand (sCD40L), oxidized low-density lipoprotein (ox-LDL), human matrix Gla protein (MGP) and fetuin-A. Our results showed that CRP (P < 0.0001), sCD40L (P < 0.0001) and MGP (P < 0.0001) were increased in the patient cohort. Fetuin-A showed decreased serum levels in patients with psoriasis (P < 0.0001), whereas ox-LDL did not show any significant difference. In multivariate analyses controlling for sex, age and BMI, these findings were confirmed. Thus, CV biomarkers are altered in patients with psoriasis. If the decrease in fetuin-A as well as the increase in sCD40L can be proven in further studies, these biomarkers may help to characterize a subgroup of patients who are at risk to develop CVD and/or monitor the effect of therapeutic antipsoriatic strategies on concomitant diseases. This knowledge may be useful in the management of high-need patients with psoriasis.

Abstract
CONTEXT Soluble CD40 ligand (sCD40L) is known to be elevated in different clinical situations including hypercholesterolemia, acute coronary syndromes, and type 2 diabetes mellitus (T2DM), Data about the relationship between type 1 diabetes mellitus (T1DM) and sCD40L is limited. In addition, the potential role ofsCD40Lin the pathogenesis of vascular complications in children and adolescents with T1DM is to be clarified. Hence, the study aimed at assessment of sCD40L levels in children and adolescents with T1DM and correlation of these levels with glycemic control and microalbuminuria. SETTINGS AND DESIGN Cross-sectional controlled study. MATERIALS AND METHODS The study was performed in the Pediatric Endocrinology and Diabetes Unit, Assuit University Children Hospital, Assiut, Egypt. It included 70 children and adolescents with T1DM (mean age 14. 76 ± 2.21 years). Cases were further subdivided into 43 cases with normoalbuminuria and 27 cases with microalbuminuria according to presence or absence or microalbuminuria in fresh urine samples. Twentyfive healthy subjects, age- and sex-matched were included as control group (mean age = 13.62 ± 2.11 years). Studied cases were subjected to medical history, clinical examination, and laboratory assessment of fasting blood glucose (FBG), lipid profile, glycosylated hemoglobin (HbA1c), and sCD40L were performed. RESULTS Mean HbA1c and sCD40L were significantly higher in diabetic children (n = 70) compared to control (n = 25) (P < 0.001 for each). Mean HbA1c and sCD40L levels were significantly higher in microalbuminuric cases (n = 27) compared to normoalbuminuric cases (n = 43) (P < 0.05 and <0.01, respectively). We also observed a significant positive correlation between sCD40L levels and the age, diabetes duration, HbA1c, and urinary albumin creatinine ratio. CONCLUSIONS The high serum sCD40L levels in children and adolescents with T1DM particularly in those with microalbminuria and its positive correlation with diabetes duration, urinary albumin excretion, and glycemic control may reflect the role of sCD40L in diabetic vasculopathy in the pediatric age group. Moreover, measurement of serum sCD40L levels in poorly controlled patients would help to identify those at high risk of developing nephropathy.

Abstract
AIM: To observe whether Salvianolate Injection has a therapeutic effect on colitis and to discuss the possible mechanisms involved.
METHODS: 50 Balb/c mice were randomly divided into a control group, a model group, and low-, medium-, and high-dose interventional groups. Colitis was induced by oral administration of 5% DSS for 7 d. Indices were determined 14 d after colitis induction.
RESULTS: Treatment with Salvianolate Injection could reduce colonic inflammation induced with DSS (P < 0.01). Immunohistochemistry analysis showed that treatment with different doses of Salvianolate Injection significantly reduced CD40/CD40L protein expression compared to the model group (CD40: 20.50 μm2 ± 1.517 μm2, 15.50 μm2 ± 4.680 μm2, 13.33 μm2 ± 0.816 μm2vs 30.33 μm2 ± 4.227 μm2, all P < 0.01; CD40L: 23.17 μm2 ± 2.714 μm2, 15.50 μm2 ± 2.739 μm2, 14.17 μm2 ± 4.262 μm2vs 27.83 μm2 ± 3.710 μm2, all P < 0.01). RT-PCR analysis showed that treatment with different doses of Salvianolate Injection significantly reduced CD40/CD40L mRNA expression compared to the model group (CD40: 1.20% ± 0.30%, 0.78% ± 0.26%, 0.41% ± 0.15% vs 1.78% ± 0.41%, all P < 0.01; CD40L: 2.59% ± 1.68%, 1.75% ± 0.64%, 1.11% ± 0.53% vs 3.54% ± 0.85%, all P < 0.01). The concentration of sCD40L in medium was decreased in the medium- and high-dose interventional groups compared to the model group (2.12 ng/mL ± 0.18 ng/mL, 1.96 ng/mL ± 0.12 ng/mL vs 5.62 ng/mL ± 0.36 ng/mL, P < 0.01).
CONCLUSION: Salvianolate Injection can exert a therapeutic effect on colitis in mice possibly by reducing sCD40L and thus restraining the CD40/CD40L pathway.

Abstract
BACKGROUND Hypertension is associated with an increase in platelet activation and endothelial dysfunction and leads to a tendency to cardiovascular events (CVEs). Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) is a novel platelet activation marker. There are currently no studies showing the level of SCUBE1 in hypertensive patients. The purpose of this study was to determine the level of SCUBE1 in this patient group and to investigate the parameters affecting that level. METHODS Forty-five newly diagnosed, untreated, stage 1 hypertensive patients and 21 healthy individuals were included. Blood specimens were collected to determine SCUBE1, soluble CD40 ligand, prothrombin time, partial thromboplastin time, fibrinogen, D dimer, hemogram, lipid parameters, blood urea nitrogen, creatinine, and uric acid levels. The relation between SCUBE1 level and demographic data and biochemical parameters was then investigated. RESULTS SCUBE1 and sCD40L levels obtained from plasma specimens from the hypertensive group were significantly higher than those of the control group (P < 0.001; P < 0.05, respectively). Hypertensive group blood pressure (BP) values and uric acid, low-density lipoprotein, total cholesterol, and triglyceride levels were also statistically higher than those of the control group. Parameters affecting SCUBE1 levels were systolic and diastolic BP, sCD40L, lipid parameters, and uric acid levels. CONCLUSIONS We show elevated levels of SCUBE1, a novel platelet activation marker, in primary hypertensive patients. We think that, when supported by further clinical studies, this newly described marker may be useful in the monitoring of CVEs in this patient group, in which platelet activation is known to be associated with such events.

Abstract
CD40-CD40L interaction plays a significant role in the pathogenesis of atherosclerosis and coronary artery disease. The clinical predictive value of Soluble CD40 Ligand (sCD40L) was evaluated in patients with Acute Coronary Syndrome (ACS) and Non-Cardiac Chest Pain (NCCP). The levels of serum soluble CD 40 ligand were measured by ELISA in 485 patients admitted to emergency care unit, of which 89 patients were diagnosed as NCCP. The levels of sCD40L were significantly increased in patients with ACS when compared to controls and NCCP. Receiver Operator Characteristic (ROC) Curve analysis showed sCD40L to be a good discriminator between patients with ischemic heart disease and patients without ischemic heart disease. The area under the curve was found to be 0.940 with 95% CI (0.915 to 0.960) (P<0.0001). The cut off value from the ROC curve was 2.99 ng/ml, above which sCD40L was considered to be positive. Combined assessment of sCD40L, Troponin I and CK-MB enhanced the risk prediction and early classification of patients. sCD40L seems to be a promising biomarker for identification and risk stratification for patients with acute coronary syndrome.

Abstract
AIM: To determine the expression levels of soluble CD40L in sera of patients with inflammatory bowel disease (IBD), and to study its clinical significance to the pathogenesis.
METHODS: Sera were collected from 12 patients with crohn's disease (CD), 42 patients with ulcerative colitis (UC) and 34 healthy controls. sCD40L was analyzed by ELISA. These patients were treated routinely and sCD40L was detected after clinical remission.
RESULTS: Levels of sCD40L were significantly increased in sera of patients with CD and UC compared with healthy controls (2456.5 ± 264.3 ng/L, 2105.4 ± 238.1 ng/L vs 564.8 ± 188.6 ng/L, both P < 0.005). Moreover, sCD40L was found to be markedly decreased in sera from IBD patients after effective treatment (P < 0.005). Further analysis demonstrated that no relationship was present between sCD40L and other biochemical parameters such as CRP and liver and kidney function tests.
CONCLUSION: sCD40L is significantly increased in sera from patients with IBD, suggesting that sCD40L is involved in the development of disease. Therefore, it can be used to evaluate early diagnosis and predict efficacy and prognosis.
