Serum amylase is a representative enzyme secreted by the salivary gland and pancreas. This study investigates the clinical significance of serum amylase levels in Sjögren's syndrome (SS). Totally, 70 female subjects were enrolled, who were diagnosed as SS and had no accompanying afflictions that affected the serum amylase levels. Unstimulated salivary flow rate (U-SFR) and stimulated SFR (S-SFR), salivary gland scan, and disease activity markers (ESSDAI and ESSPRI), as well as blood tests including ESR, CRP, and amylase, were evaluated. Serum amylase showed significant positive correlation with the U-SFR and S-SFR, and was increased with higher ejection fraction (EF) of the parotid gland. However, there was no significant correlation with disease activity and inflammatory markers. Based on their average amylase levels, subjects were divided into two groups. The group with higher serum amylase levels showed a statistically significant increase in the S-SFR and EF of the parotid gland. Considering the results of the salivary gland scan, we conclude that serum amylase is significantly correlated with SFR and the EF of the parotid gland, thereby indicating that the salivary gland function remains intact in SS.

Objectives Despite the growing research interest in the role of immunological markers in schizophrenia, a few studies, with conflicting results, have focused on the association between high sensitivity C-reactive protein (hs-CRP) levels and clinical characteristics in schizophrenia. The aim of the present study was to examine the association of serum hs-CRP with psychopathology in schizophrenia. Methods Fifty-five inpatients with schizophrenia or schizoaffective disorder were enrolled. Serum levels of hs-CRP were measured, and each patient was assessed with the Korean version of the Positive and Negative Syndrome Scale (PANSS). Results In correlation analysis of hs-CRP with PANSS subscales, positive subscale score has significant positive correlation (r = 0.271, p = 0.046). In independent t-test analysis, subjects with hs-CRP > 0.3 mg/dL (elevated CRP group, n = 43) had significantly higher PANSS positive subscale score (t = -3.273, df = 24.107, p = 0.003) than those with hs-CRP ${\leq}$ 0.3 mg/dL (normal CRP group, n = 12). Conclusions Elevated serum levels of high sensitivity C-reactive protein in schizophrenia are associated with the severity of psychotic symptoms.

Objectives : Delirium is a temporary brain dysfunction and systemic inflammation is important factor in its pathophysiology. Whether the neutrophil-lymphocyte ratio (NLR), one of the inflammatory markers, can be used as an inflammatory marker in delirium patients was investigated in comparison with C-reactive protein (CRP). Methods : We retrospectively reviewed the medical records of patients who were referred for consultation for delirium at hospital for one year. The NLR and CRP values at admission and delirium status were divided into the medical and the surgical treatment group, and the interaction between them was analyzed through repeated measures ANOVA. Results : NLR was maintained without significant difference before and after delirium in the medical treatment group and the surgical treatment group, but CRP decreased in the medical treatment group and increased in the surgical treatment group during delirium, showing a significant interaction. Conclusions : In delirium patients, the NLR remained constant, but the CRP differed according to the treatment group and the delirium state. This suggests the possibility that NLR could be used complementary to CRP as an inflammatory marker in delirium patients.

Abnormalities of trophoblast due to early inflammation in pregnancy increase the expression of CRP and affect maternal-fetal interactions, leading to preterm birth and preeclampsia. However, biomarkers related to the regulation of CRP expression have not been found. In this study, miRNA associated with increased expression of CRP was identified and their expression was analyzed to reveal biomarkers involved in the regulation mechanism of trophoblast inflammation through miRNAs. miRNAs that were predicted to regulate CRP gene expression in miRNA databases (mirna, TargetScan, MicroCosm) were screened and HTR-8/SVneo cell lines were treated with LPS (20 ng/mL) to induce inflammatory responses in vitro, with selected miR-7, miR-150, miR-186 and miR-424. The expression was analyzed by qRT-PCR. As a result, expression of CRP was significantly increased in LPS-treated trophoblast (p<0.001) and miR-150 and miR-424 expression were significantly decreased (p<0.001). Thus, miR-150 and miR-424 are involved in the regulation of CRP expression in inflammatory-induced trophoblast and may be useful for the prenatal diagnosis of inflammatory obstetric diseases.

Cytokines play a pivotal role in systemic inflammatory response following cardiac surgery with cardiopulmonary bypass (CPB). The purpose of this study was to investigate the perioperative changes in proinflammatory [tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-6 (IL-6)] and antiinflammatory cytokines [interleukin-10 (IL-10)], and each correlation between the cytokines and other variables in valvular heart surgery with CPB. Serum IL-6 and IL-10 levels and leukocyte counts significantly increased following CPB. CPB caused hepatic, renal and myocardial dysfunctions. IL-6 levels had positive correlations with IL-10 levels at postoperative periods. TNF-$\alpha$ levels had correlations with leukocyte counts and myocardial marker levels at postoperative 24 hr (PO-24 h). Furthermore, IL-6 or IL-10 levels had positive correlations with other variable such as hepatic, renal or myocardial marker at postoperative periods. These results showed that balance between proinflammatory and antiinflammatory cytokines is maintained during cardiac surgery with CPB, and that these cytokines exert postoperatively inflammatory and antiinflammatory reactions.

Previously, we have shown that Schisandra chinensis (Turcz.) Baill. (S. chinensis) has a protective effect against endoplasmic reticulum (ER) stress-induced hepatic steatosis. Gomisin A is a bioactive phytoestrogen derived from S. chinensis. In the present study, the in vitro and in vivo effects of gomisin A on ER stress and hepatic steatosis were investigated. We quantified the expression of markers of ER stress, including glucose regulated protein 78 (GRP78), C/EBP homolog protein (CHOP), and X-box-binding protein-1 (XBP-1), in HepG2 cells treated with tunicamycin or palmitate. Tunicamycin treatment in HepG2 cells induced the expression of markers of ER stress, including GRP78, CHOP, and XBP-1c. However, treatment with gomisin A reduced the expression of markers of ER stress. These inhibitory effects were also observed in palmitate-incubated HepG2 cells. The in vivo inhibitory effects of gomisin A were assessed in mice injected with tunicamycin or fed with a high fat diet (HFD). Gomisin A reduced the expression of markers of ER stress and decreased triglyceride levels in the livers of mice after tunicamycin injection or HFD feeding. Furthermore, gomisin A decreased the expression of inflammatory genes in palmitate-incubated HepG2 cells and the liver of HFD-fed obese mice. These results suggest that gomisin A inhibits ER stress and ameliorates hepatic steatosis induced by ER stress.

This study was carried out on thirty men to define the association of inflammatory markers with physiological factors on one-time aerobic exercise (for 15 min. Post-exercise interleukin-6 (IL-6), mean corpuscular hemoglobin concentration (MCHC), heart rate (HR), systolic blood pressure (SBP), and pulsatility and resistance index of middle cerebral artery (PI and RI, respectively) levels were elevated compared to those measured pre-exercise. Total leukocyte and platelet counts, high-sensitivity C-reactive protein (hs-CRP), free radical (FR), and low density lipoprotein cholesterol (LDL) levels tended to decrease after exercise. Pre-exercise IL-6 levels were positively correlated with pre-exercise SBP levels, while post-exercise IL-6 level was positively correlated with post-exercise PI and RI levels. Post-exercise, hs-CRP levels were negatively related to SBP and HR. Pre-exercise, FR levels were positively associated to SBP, DBP, and HR. Post-exercise FR levels were negatively related to the post-exercise blood flow velocity in middle cerebral artery. Pre-exercise erythrocyte indices (RBC, MCV, MCH, and MCHC levels) were in inverse proportion to pre-exercise IL-6 levels. Post-exercise FR levels were inversely related to post-exercise total leukocyte, lymphocyte, monocyte, and MCH levels. Pre-exercise $Mg^{++}$ levels were in inverse proportion to pre-exercise IL-6, hs-CRP, or FR levels. These findings suggest that one-time aerobic exercise offers a significant relationship between inflammatory markers and some biochemical markers or electrolytes. Further studies need to be carried out for investigation of differences between genders or age groups following one-time or regular aerobic exercise.

The aim of this study is to investigate neutrophil activation markers among canine ICU (intensive care unit) control, systemic inflammatory response syndrome (SIRS) and sepsis. These markers include WBC (white blood cells), platelets counts, blood film examination (neutrophilic band to segmentation ratio and neutrophilic degenerative changes), and flow cytometric analysis (CD11b expression of neutrophils). As a result, the mean CD11b fluorescence intensity of neutrophils and the neutrophilic degenerative change scores were both significantly higher in sepsis group (P<0.05). In addition, mortality was also found to be correlated with the up-regulation of CD11b expression in circulating neutrophils. This study demonstrates that CD11b expression of neutrophils could be more a reliable biomarker to predict prognosis in ICU patients than traditional blood film examination according to this study.

This study confirmed the effects of improving lung damage of celecoxib using an animal model of chronic obstructive pulmonary disease(COPD). It was induced in models LPS + CSE and performed in vitro and in vivo. MTT assay and real-time PCR were performed in MRC5 cells as in vitro, and mRNA expression, BALF, collagen content, and protein expression were confirmed as in vivo. Celecoxib reduced the number of inflammatory cells, cytokine and soluble protein accumulation in BALF, decreased body weight and lung weight in animal models, and improved lung collagen deposition. In addition, the reduction of EMT markers was confirmed through Western blotting and real-time PCR. Consequently, celecoxib is thought to improve lung damage of COPD induced to LPS+CSE by regulating EMT.
