Objective. Zinc-α2-glycoprotein (ZAG) has recently been proposed as a new adipokine involved in body weight regulation. The purpose of this study is to investigate serum levels of ZAG in patients with hypertension and its association with related characteristics. Methods. 32 hypertension patients and 42 normal controls were recruited and the relationship between serum ZAG, total and high molecular weight (HMW) adiponectin, and tumor necrosis factor-α (TNFα) determined by enzyme-linked immunosorbent assay (ELISA) and metabolic-related parameters was investigated. Results. Serum ZAG concentrations were significantly lowered in patients with hypertension compared with healthy controls (61.4 ± 32 versus 78.3 ± 42 μg/mL, P<0.05). The further statistical analysis demonstrated that serum ZAG levels were negatively correlated with waist-to-hip ratio (WHR) (r=−0.241, P<0.05) and alanine aminotransferase (ALT) (r=−0.243, P<0.05). Additionally, serum HMW adiponectin significantly decreased, while TNFα greatly increased in hypertension patients as compared with healthy controls (2.32 ± 0.41 versus 5.24 ± 1.02 μg/mL, 3.30 ± 1.56 versus 2.34 ± 0.99 pg/mL, P<0.05). Conclusions. Serum ZAG levels are significantly lowered in hypertension patients and negatively correlated with obesity-related item WHR, suggesting ZAG is a factor associated with hypertension.

Abstract The aim of this project was to evaluate the relationship of matrix metalloproteinase-9 (MMP-9) genetic variation and its serum concentration with autism spectrum disorder (ASD). One hundred ASD and 120 controls were enrolled in this study. Genomic DNA was extracted from blood and MMP-9 polymorphism was determined by polymerase chain reaction restriction fragment length polymorphism and serum levels were measured by enzyme-linked immunosorbent assay. The frequencies of CC, CT, and TT genotypes were 72%, 26%, and 2% in controls and 31%, 57%, and 12% in ASD, respectively. The frequencies of C and T alleles in ASD were 59.5% and 40.5%, and controls were 86% and 14%, respectively. There is a significant increase in serum MMP-9 levels in ASD as compared to controls. We have also shown that TT genotype is significantly associated with increase serum MMP-9 levels in patients (TT, CT, and CC serum levels were 91.77 ± 10.53, 70.66 ± 7.21, and 38.66 ± 5.52 and in controls were 55.55 ± 11.39, 42.66 ± 7.85, and 30.55 ± 6.34 ng/ml, respectively). It is concluded that there is a significant association between rs3918242 MMP-9 polymorphism and its serum concentration with autism. We also suggest that TT genotype is associated with increased MMP9 expression and may be a risk factor for ASD.

Abstract Objective. It was previously demonstrated that cutaneous vasculitis, including IgA vasculitis and cutaneous arteritis (CA), is associated with the presence of IgM antibodies (Abs) against the phosphatidylserine/prothrombin complex (PS/PT). Recently, novel enzyme-linked immunosorbent assay kits for the detection of IgG and IgM anti-PS/PT (aPS/PT) Abs have become commercially available.Methods. The prevalence of serum IgG and IgM aPS/PT Abs in both cutaneous and systemic vasculitis was determined using these kits. In addition, to examine whether aPS/PT Abs were involved in the pathogenesis of cutaneous vasculitis, inbred wild-type rats were intravenously administered with a rat IgM class aPS/PT monoclonal Ab established previously or with rat immunoglobulins as controls. To express PS on the surface of vascular endothelium, these rats were given a subcutaneous injection of cell-free histones (250 µg/ml, 300 µl/site) 2 hours in advance. Results. Serum IgM aPS/PT Ab levels were elevated in patients with systemic vasculitis with skin involvement and CA compared to those in patients with systemic vasculitis without skin involvement and healthy controls. There was no significant difference in the serum levels of IgG aPS/PT Abs between the patients and healthy controls. Correspondingly, inbred wild-type rats intravenously administered with the aPS/PT monoclonal IgM Ab after appropriate priming—subcutaneous histone injection—developed cutaneous vasculitis. Some rats given rat IgM instead of the aPS/PT monoclonal Ab also developed cutaneous vasculitis, whereas vasculitis did not occur in rats given IgG or only priming by histones. Conclusion. IgM aPS/PT Abs could be involved in the pathogenesis of cutaneous vasculitis.

Background：Esophagogastric junction tumor (EGJ) is a rare but fatal disease with a rapid rising incidence worldwide in the late 20 years, and it lacks a convenient and safe method for diagnosis. This study aimed to evaluate the potential of serum CYR61 as a biomarker for the diagnosis of EGJ tumor. Methods: Enzyme-linked immunosorbent assay (ELISA) was used to estimate CYR61 levels in sera of 152 EGJ tumor patients and 137 normal controls. Receiver operating characteristics (ROC) was carried out to evaluate the diagnostic accuracy. The Mann–Whitney’s U test was used to compare the difference of serum levels of CYR61 between groups. And chi-square tests were employed to estimate the correlation of the positive rate of serum CYR61 between/among subgroups. Results: Serum CYR61 levels were statistically lower in EGJ tumor and early-stage EGJ tumor patients than those in normal controls (P&lt;0.0001). The sensitivity, specificity, and the area under the curve (AUC) of this biomarker in EGJ tumor were 88.2%, 43.8% and 0.691, respectively, and those for early stage of EGJ tumor were 80.0%, 66.4% and 0.722, respectively. Analyses showed that there was no correlation between the clinical data and the levels of CYR61 (P&gt;0.05). Conclusion: This study showed that CYR61 might be a potential biomarker to assist the diagnosis of EGJ tumor.

This study aims to evaluate serum levels of the Dehydroepiandrosterone sulfate (DHEA-S) and its relationship with some sex hormones such as Follicle stimulating hormone (FSH), Luteinizing hormone (LH), prolactin and testosterone hormone and the infertility type in some infertile Iraqi men. Blood and seminal fluid samples from (60) idiopathic male infertile and (60) healthful individuals as a control group aged (18 to 60 year) were collected from private clinics. Serum hormones (DHEA-S, FSH, LH, prolactin and testosterone) were measurement using Enzyme Linked Immunosorbent Assay (ELISA). The levels of DHEA-S, FSH, LH and prolactin are significantly higher (P≤0.01) expect of the testosterone level was significantly decreased (P≤ 0.01) in the infertile men as compared with control group. High significant differences (P≤0.01) were recorded when comparing the hormonal levels (DHEA-S, FSH, LH, prolactin and testosterone) according to the age groups. There are significant differences (P≤ 0.01) in levels of (DHEA-S, FSH, LH, prolactin and testosterone) in the infertility period.  Smoker infertile men have high levels (P≤ 0.05) in the DHEA-S and LH while have low levels in the prolactin hormones compared with control. Patients with family history have shown significant differences (P≤0.05) in the levels of DHEA-S, FSH, LH and prolactin. In conclusion, this study revealed significantly increase in the DHEA-S levels in the infertile men and negative correlation between DHEA-S and FSH. Therefore, DHEA-S has important role in the diagnosis and follow up of the male infertility.

Abstract Background: We investigated bilateral tear cytokine levels including interleukin (IL)-1β, IL-10, IL-17, tumor necrosis factor (TNF)-α and Matrix metalloproteinase-9 (MMP-9) in patients with fungal keratitis(FK). Meanwhile, we evaluated the relationship between the changes of tear cytokines with corneal perception and pain in infected eyes, and the relationship between tear cytokines and tear film function in contralateral uninfected eyes .Methods : A total of 60(20 FK, 20 contralateral, 20 healthy controls) tear samples were collected prospectively and analyzed by enzyme linked immunosorbent assay(ELISA). Approximately 50 to 60 ul of tear samples in each case were collected. Meanwhile ,we analyzed the changes of visual analogue scale(VAS), tear breakup time (TBUT), Schirmer I test (SIT) and corneal perception compared with healthy controls. Results :The concentrations of IL-1β, IL-10 and IL-17 increased in bilateral eyes compared with healthy controls(P<0.05). The tear concentrations of MMP-9 , TNF-α only significantly increased in affected eyes (P <0.05). Patients with FK showed significant reduction in corneal perception of infected eyes compared with controls(P<0.05). Corneal perception of the normal eyes in FK patients was slightly lower than that of control group, but there was not statistical difference (P>0.05).TBUT and SIT of contralateral uninfected eyes were significantly lower than that of control group(P<0.05), which were significantly correlated with levels of IL-1β, IL-17(P<0.05). SIT were also negatively correlated with MMP-9(P<0.05), while the levels of IL-1β, IL-10, IL-17, TNF-α and MMP-9 in the tears of the healthy control group had no significant correlation with TBUT and SIT indicators(P>0.05).The corneal perception and VAS score of the affected FK eyes showed correlation with IL-1β, IL-17 and TNF-α(P<0.05).In addition, concentration of IL-10 inversely was correlated with VAS (P<0.05). Conclusion: Proinflammatory tear cytokines are elevated in bilateral eyes with unilateral FK as associated with tear film function ,pain and corneal sensitivity.

Abstract Glucocorticoid hormone levels vary within a forager based upon environmental stressors such as illumination and riskier habitats, and a forager’s response to environmental variables depends upon its glucocorticoid levels. Here, we report on a laboratory experiment in which we manipulated cortisol in Allenbyi’s gerbils (Gerbillus andersoni allenbyi) to test the relationship between cortisol and behavior. We then quantified the resulting blood cortisol levels and feeding behavior in gerbils. Thirty gerbils were injected with 21-day slow-release cortisol pellets drawn from 5 different dosages. We quantified the physiological response to pellet implantation in gerbils by measuring cortisol level in blood serum using ELISA (Enzyme Linked Immunosorbent Assay). We fed gerbils daily by mixing millet seeds into the sand inside rodent cages and measured the remaining seeds the following day to quantify feeding efforts. Some evidence supports that subcutaneous supplementation of glucocorticoids (GCs) in the gerbils led to higher blood serum levels. Cortisol levels varied according to time period of measurement. Gerbils that received lower dosages consumed most of the food presented to them when compared to those receiving the highest doses. In this manner, we delineate a pattern on cortisol hormone level variation over time following dosing and consequences in feeding behavior.

SummaryImmune dysfunction has been proposed as a mechanism for the pathophysiology of autistic-spectrum disorders. The selectin family of adhesion molecules plays a prominent role in immune/inflammatory responses. We determined the serum levels of three types of soluble-form selectin (sP, sL and sE) in 15 men with high-functioning autism and 22 age-matched healthy controls by enzyme-linked immunosorbent assay. Levels of sP-selectin and sL-selectin were significantly lower in patients than in controls. Furthermore, sP-selectin levels were negatively correlated with impaired social development during early childhood.

AimsExplore the relationship between levels of plasma Aβ1–40, Aβ1–42 and heat shock protein 70 (HSP70) in patients with Alzheimer disease (AD) and vascular dementia (VD) and in elderly non-demented controls.Methods23 patients with AD and 21 patients with VD who meet diagnostic criteria of the Diagnostic Statistical Manual 4th edition and 20 control subjects were enrolled, administered the Mini-Mental State Exam (MMSE) and the Activity of Daily Living (ADL) inventory and their levels of plasma Aβ1–40, Aβ1–42 and HSP70 were measured by sandwich enzyme-linked immunosorbent assay.ResultsThe levels of plasma Aβ1–40, Aβ1–42 and the Aβ1–40/Aβ1–42 ratio were not significantly different across groups, but levels of plasma HSP70 in VD patients was significantly higher than in AD patients and in normal controls (3.19 vs 1.91 vs 1.43ng/ml, respectively; F=6.464, P=0.003). In the AD group MMSE scores were inversely correlated with ADL scores (r=-0.617, P=0.002) and with levels of plasma HSP70 (r=-0.437, P=0.037); but HSP70 levels were positively correlated with age (r=0.616, P=0.002) and with plasma Aβ1–40 (r=0.497, P=0.016) in AD group. In the VD group levels of plasma HSP70 were positively correlated with plasma Aβ1–40 (r=0.436, P=0.048).ConclusionsOur findings provide further evidence that high plasma HSP70 levels may play a role in the diagnosis and differential diagnosis of AD. HSP70 levels in AD patients is inversely associated with cognitive performance and positively correlated with plasma Aβ1–40. Plasma HSP70 in VD patients is significantly elevated and positively correlated with plasma Aβ1–40.

Objective: The purpose of this study was to explore the application of dexmedetomidine (Dex) in cardiopulmonary bypass. Methods: A total of 60 patients undergoing elective cardiopulmonary bypass were divided into control (C) group and Dex group. In the Dex group, appropriate amount of Dex was added into the membrane lung prefilling solution before anesthesia induction, while those in control group were given normal saline. The levels of mean arterial pressure (MAP) and heart rate (HR) at different times were measured. The levels of cardiac troponin I (CTNI), malondialdehyde (MDA), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α) at different points (T0/T1/T2/T3/T4) in both groups were measured by enzyme-linked immunosorbent assay kits. Results: The intraoperative and postoperative levels of MAP and HR in the 2 groups were significantly lower than those preoperatively ( P < .05). The levels of MAP and HR in the Dex group were significantly lower than those of the C group ( P < .05). The levels of CTNI/MDA/IL-6/TNF-α at different points in both groups were significantly higher than those at T0 ( P < .05). The serum levels of CTNI, MDA, IL-6, and TNF-α in the Dex group at T1/T2/T3/T4 were significantly lower than those in the C group ( P < .05). The rate of arrhythmia in the Dex group was significantly lower than that in the C group ( P < .05). Conclusion: Dexmedetomidine has a stable effect in cardiopulmonary priming solution.

Objective Complement C1q tumor necrosis factor-related proteins (CTRPs), belonging to the CTRP superfamily, are extensively involved in regulating metabolism and the immune-inflammatory response. The inflammatory process is linked to the pathogenesis of coronary artery disease (CAD). Here, we investigated the association of serum levels of CTRP1 with CAD. Methods Study participants were divided into two groups according to the results of coronary angiography: a control group (n = 63) and a CAD group (n = 76). The concentrations of serum CTRP1 and inflammatory cytokines were determined by enzyme-linked immunosorbent assay. Further analysis of CTRP1 levels in individuals with different severities of CAD was conducted. The CAD severity was assessed by Gensini score. Results Serum levels of CTRP1 were significantly higher in CAD patients than in controls (17.24 ± 1.07 versus 9.31 ± 0.56 ng/mL), and CTRP1 levels increased with increasing severity of CAD. CTRP1 levels were positively correlated with concentrations of tumor necrosis factor-α and interleukin-6. Multiple logistic regression analysis showed that CTRP1 was significantly associated with CAD. Conclusions Our data showed close associations of serum CTRP1 levels with the prevalence and severity of CAD, indicating that CTRP1 can be regarded as a novel and valuable biomarker for CAD.
