This study aimed to validate whether macrophage polarization imbalance and abnormal cytokines production occurred in pregnancy-induced hypertension (PIH) patients. PIH women (n = 26) were enrolled and the level of biochemical parameters were determined. The percentage of CD86- and CD163-positive cells, representing M1 and M2 macrophages, were determined by flow cytometry. The concentrations of cytokines (TNF-α, IL-1β, IL-4, IL-13, and IL-10) were determined using enzyme-linked immunosorbent assay kit. THP-1 cells were incubated with 10% serum from PIH and control groups, and then macrophage polarization and cytokines production were analyzed. The levels of high-density lipoprotein cholesterol and apolipoprotein A1 were significantly lower, and the levels of fasting blood glucose, total cholesterol, triacylglycerol, low-density lipoprotein cholesterol, apolipoprotein B, and lipoprotein a were significantly higher in the PIH group than that in the control group. The PIH group contained a significant higher percentage of CD86-positive cells (M1) and a significant lower percentage of CD163-positive cells (M2), representing higher M1/M2 ratio, than the control group. The PIH group expressed higher concentrations of TNF-α and IL-1β, and expressed lower concentrations of IL-4, IL-10, and IL-13 than the control group. The in vitro experiment also showed macrophage polarization imbalance and abnormal cytokines production in THP-1 cells treated with PIH serum as compared with that treated with control serum. Macrophage polarization imbalance and abnormal cytokines production occurred in PIH patients and in THP-1 cells treated with PIH serum.

Background/ Aim: Pregnancy induced hypertension (PIH) has been a leading cause of maternal mortality worldwide. It could be responsible for several complications like hemodilution, altered lipid metabolism and deficiencies of different minerals in body. Although the causes of Pregnancy induced hypertension (PIH) remains indistinct. The aim of our present study was to evaluate the changes in magnesium serum levels and lipid profile in hypertensive and normotensive pregnant women. Materials and Methods: An analytical case control study comprising 60 individuals was designed. From which 30 normotensive pregnant women served as control group (A) and 30 pregnancy induced hypertensive women served as case group (B). Patients with pre-existing hypertension were excluded. Results: The independent t-test was used for comparison of various parameters between group A and B. Triacylglycerol (TAG) and low density lipoprotein cholesterol (LDL-C) levels were significantly high in PIH (B) as compare to normotensive group (A). Mean serum values of TG were measured as (195.73 ± 70.28 vs 156.27 ± 55.60 mg dL-1) and LDL-C vs control (87.33 ± 37.74 vs 69.45 ± 28.58 mg dL-1) in PIH and normotensive groups respectively. HDL-C in PIH vs Control (47.40±1.12 vs 54.43 ±1.27 mg dL-1) and Mg+2 PIH vs control (1.36±0.07 vs 1.94±0.35 mg dL-1) were measured respectively. High density lipoprotein cholesterol (HDL-C) and magnesium Mg+2 levels were significantly reduced in PIH. Conclusion: The lower serum magnesium levels and abnormal lipids profile may indicate their possible role as risk factors in the development of PIH in pregnant women. Hence initial diagnosis of hypomagnesemia in PIH cases may help in minimizing the complications and development of new cure strategies.

Background/aim: Adropin is a peptide-structure hormone that plays a role in preventing the development of insulin resistance, which has been linked to obesity and metabolic regulation. The purpose of this study is to assess serum adropin levels and their relationship with metabolic parameters in psoriasis vulgaris patients both with and without metabolic syndrome (MetS). Methods: Fifty-three patients and twenty-six healthy controls were included in this study. Serum adropin levels, fasting blood glucose, fasting plasma insulin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, and triglyceride levels of all participants were analyzed. Enzyme-linked immunosorbent assay was used to measure serum adropin levels. Results: Serum adropin levels in psoriatic patients without MetS were 2.94±0.56 ng/ml, in psoriasis patients with MetS were 2.49±0.77 ng/ml and were 3.37±0.71 ng/ml in control group. Multivariate logistic regression analysis was used to evaluate adropin decreases in psoriasis patients as an independent predictor in terms of the presence of MetS. Conclusion: The serum levels of adropin in psoriasis patients were significantly lower in the presence of MetS, and this decrease was more prominent than in those without MetS. Adropin may be a responsible factor for metabolic disorders and the development of MetS in psoriasis patients. Key words: Psoriasis, metabolic syndrome, adropin

Purpose: The current study was conducted in order to investigate the role of Forkhead box O1 and p21-mediated macrophage polarization in postoperative cognitive dysfunction induced by sevoflurane. Methods: There involved a total of 30 healthy mice that were randomly divided into two groups: control group (without any treatment) and anaesthesia group (treated with sevoflurane inhalation). The effects of sevoflurane on cognitive function (memory) in mice were studied by trace fear conditioned reflex, and the effects of systemic inflammation and behavior after operation were measured by enzyme-linked immunosorbent assay (ELISA), the concentrations of CD163 and tumor necrosis factor-α (TNF-α) were measured. The expression of macrophage phenotype was observed by immunofluorescence staining, the expression levels of M1 and M2 markers mRNA were detected by real-time fluorescence quantitative PCR (RT-PCR), and the expression levels of FoxO1 and p21 were analyzed by immunoblotting (Western blot). Results: Compared with the control group, the freezing time in the anesthesia group was lower than that in the control group (P<0.01), indicating that sevoflurane anesthesia led to the decrease of cognitive ability. The blood concentrations of CD163 and TNF-α increased significantly at 24 h after the operation with sevoflurane anesthesia (P<0.05). Fluorescence microscopic observation showed that M2 was the main type of macrophages in normal tissues, while M1 and M2 phenotypes were highly expressed in sevoflurane anesthetized tissues at the same time, especially in M1 phenotypes (P<0.01). The polarization of macrophages in the anesthetic group showed the high level of M1 mRNA, and the expression levels of TNF-α, monocyte chemotactic protein 1(MCP-1) and Interleukin-6 (IL-6)mRNA in the anesthetic group were significantly higher than those in the control group (P<0.05). The expression levels of M2 mRNA such as transforming growth factor-β (TGF-β) and IL-10 were significantly lower than those in the control group (P<0.05). Compared with the control group, the expression of FoxO1 and p21 protein in the anesthesia group was significantly lower than that in the control group with a significant statistical difference (P<0.01). Conclusion: This study offers a theoretical basis and insight for further understanding of the prevention and treatment of cognitive dysfunction induced by anesthetic drugs.

Abstract Background Laminin, one of the largest glycoproteins of the basement membrane, is an important component of the extracellular matrix. Functions of the basement membrane include regulation of cell signaling behaviors and structural support. Laminin plays a critical role in the regulation of insulin action in muscle, liver, and adipose tissue. The study mainly investigates an association between the change in serum laminin levels and insulin resistance and non-alcoholic hepatosteatosis. Methods This prospective study included a total of 90 participants; 60 patients diagnosed with Grade 2–3 non-alcoholic hepatosteatosis and 30 age- and sex-matched healthy controls between December 2019 and December 2020. Routine laboratory tests including glucose, insulin, homeostatic model of assessment-insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and C-reactive protein and laminin levels were measured in the serum of the patient and control groups. Enzyme-linked immunosorbent assay was used for the measurement of laminin levels. Results The median serum laminin levels were lower in patients with hepatic steatosis, compared to the control group (72 ng/L vs. 82 ng/L, respectively; p = 0.003). In the patients with insulin resistance, median laminin levels were lower, regardless of the presence of non-alcoholic hepatosteatosis (67 ng/L vs. 85 ng/L, respectively; p = 0.007). There was a weak, negative correlation between the laminin levels and HOMA-IR. Conclusions Our study results suggest that, although there is no exact link between laminin and non-alcoholic hepatosteatosis, serum laminin levels are lower in patients with insulin resistance by regulating the insulin effect through integrins.

Abstract BackgroundIn recent decades, the serum lipid profile of apolipoprotein(a) (Lp(a)) level and apolipoprotein B/apolipoprotein A1 ratio (Apo B/ApoA1) ratio were found more representative for serum lipid level and were recognized as the independent risk factors for various diseases. Although the serum lipid levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) were found associated with symptomatic IDH, no studies have been conducted to date for the evaluation of the association of Apo AI, Apo B, Lp(a) and Apo B/Apo AI levels with symptomatic IDH.MaterialsA total of 1,839 Chinese patients were recruited in the present study. 918 patients were diagnosed as IDH cases and were enrolled in the experimental group. A control group of 921 patients underwent a physical examination during the same period. The serum lipid levels of TC, TG, LDL-C, HDL-C, Lp(a), Apo B and Apo B/Apo AI were examined and analyzed.ResultsThe patients in the control group were collected randomly from patients who were matched with the baseline levels of the aforementioned lipid molecular. The patients with IDH exhibited significantly higher TC, TG, LDL, Apo B and Lp(a) levels compared with the control subjects. The percentage of high-TC, high-TG, high-LDL, high-Apo B and high-Lp(a) were significantly higher in the IDH group. However, hyperlipidaemia was not associated with the degenerated segment of the IDH (P=0.201). The odds ratios (OR) for the incidence of IDH with an elevated LDL-C, TC, TG, Lp(a), Apo B and Apo B/Apo AI were 1.583, 1.74, 1.62, 1.58, 1.49 and 1.39, respectively. The correlation analysis revealed the correlation between elevated LDL-C, TC, TG, Apo B, Lp(a) and incidence of IDH was significant (R2LDL=0.017; R2TC=0.004; R2TG=0.015; R2Apo B=0.004; R2LP(a)=0.021) (P<0.05). ConclusionsThe present study suggests that elevated levels of serum TC, TG, LDL, Apo B, Lp(a) and Apo B/Apo AI are associated with a higher risk for IDH.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

Objective: This study aims to investigate the expression and clinical significance of Th17 cells and related factors in peripheral blood of patients with Autoimmune Hepatitis (AIH). Methods: A retrospective selection of 100 patients with AIH were included as a study group, and 100 healthy volunteers in the outpatient clinic were selected as the control group. The levels of IL- 17, IL-6, IL-21 and TNF-α in peripheral blood of all subjects were detected by enzyme-linked immunosorbent assay and the frequency of Th17 cells and Treg cells was detected by flow cytometry. Results: Results showed that the study group had higher levels of serum total bilirubin (TBil), alkaline phosphatase (ALP), γ -glutamyltranspeptidase (γ-GT), immunoglobulin G (IgG), immunoglobulin M (IgM), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) than the control group, as well as higher levels of IL-17, IL-6, IL-21 and TNF-α in serum. The frequency of Th17 cells in peripheral blood was higher in the study group, while the frequency of Treg cells was lower. Also, serum IL-17, TNF-α levels and Th17 cells frequency were positively correlated with ALT and AST, whereas Treg cells frequency were negatively correlated with ALT and AST levels. Conclusion: Our finding demonstrates that Th17 cell frequency and their related factors IL-17 and TNF-α, are associated with liver damage, which might be used to monitor AIH disease severity.

Glycyrrhizin (GL), an important active ingredient of licorice root, which weakens the proinflammatory effects of high-mobility group box 1 (HMGB1) by blocking HMGB1 signaling. In this study, we investigated whether GL could suppress inflammation and carcinogenesis in an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced murine model of colorectal cancer. ICR mice were divided into four groups (n = 5, each)—control group, GL group, colon cancer (CC) group, and GL-treated CC (CC + GL) group, and sacrificed after 20 weeks. Plasma levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α were measured using an enzyme-linked immunosorbent assay. The colonic tissue samples were immunohistochemically stained with DNA damage markers (8-nitroguanine and 8-oxo-7,8-dihydro-2′-deoxy-guanosine), inflammatory markers (COX-2 and HMGB1), and stem cell markers (YAP1 and SOX9). The average number of colonic tumors and the levels of IL-6 and TNF-α in the CC + GL group were significantly lower than those in the CC group. The levels of all inflammatory and cancer markers were significantly reduced in the CC + GL group. These results suggest that GL inhibits the inflammatory response by binding HMGB1, thereby inhibiting DNA damage and cancer stem cell proliferation and dedifferentiation. In conclusion, GL significantly attenuates the pathogenesis of AOM/DSS-induced colorectal cancer by inhibiting HMGB1-TLR4-NF-κB signaling.

Objective. To determine the utility of a school-based questionnaire, to identify adolescents with adverse coronary risk factor levels. Design. In Muscatine, IA, students (9th through 12th grade) completed a questionnaire providing medical history information about first- and second-degree relatives. Anthropometric measures were obtained and blood pressure, lipid, lipoprotein, and apolipoprotein levels were determined. Results. A history of parental coronary heart disease (CHD) was rare and a history of parental high cholesterol frequently was unknown; however, when known, a history of high cholesterol or early (30 to 55 years of age) or later (&gt;55 years of age) CHD (myocardial infarction, coronary bypass, or death from a heart attack) in grandfathers enriched the identification of adolescents with adverse coronary risk factors. Parental history of CHD was associated with an increased risk for high body mass index and low apolipoprotein A1 levels in their children. Grandfather history of early or later CHD was associated with an increased risk for low apolipoprotein A1 and high density lipoprotein cholesterol levels and high body mass index in their grandchildren. Students with positive grandfather histories of high cholesterol had higher total cholesterol, low density lipoprotein cholesterol, apolipoprotein B, and low density lipoprotein cholesterol to high density lipoprotein cholesterol ratios. Grandmother histories, because most were negative, did not help identify adolescents in this population with adverse coronary risk factors. Conclusions. A parental history of CHD as well as a grandfather history of high cholesterol or CHD enriches the identification of children with adverse coronary risk factor levels. The positive predictive values associated with using a school-based history obtained from adolescents, many with the aid of their parents, are small and many adolescents do not know their family history. It is essential that pediatricians inquire about parental and especially grandparental medical histories in accordance with the National Cholesterol Education Program guidelines to help identify children at highest familial risk. The importance of determining parental and grandparental histories of CHD or hypercholesterolemia should be emphasized to families who are uncertain of their histories to identify children and adolescents who require a physician's care. It is also important for pediatricians to remind their colleagues who care for patients with premature ischemic heart disease to refer their progeny for pediatric care so that their lipids and lipoproteins may be screened and counseling provided.

Abstract Background Limited research is available concerning the relationship between oxidative stress and inflammation parameters, and simultaneously the effects of rosuvastatin on these markers in patients with hypercholesterolemia. We aimed to investigate the connection between cytokines and oxidative stress markers in patients with hypercholesterolemia before and after rosuvastatin treatment. Methods The study consisted of 30 hypercholesterolemic patients diagnosed with routine laboratory tests and 30 healthy participants. The lipid parameters, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), paraoxonase-1 (PON1) and malondialdehyde (MDA) levels in controls and patients with hypercholesterolemia before and after 12-week treatment with rosuvastatin (10 mg/kg/day), were analyzed by means of enzyme-linked immunosorbent assay. Results It was found that a 12-week cure with rosuvastatin resulted in substantial reductions in IL-1β, IL-6 and TNF-α and MDA levels as in rising activities of PON1 in patients with hypercholesterolemia. Before treatment, the PON1 levels were significantly negatively correlated with TNF-α and IL-6 in control group, while it was positively correlated with TNF-α in patients. Conclusion Our outcomes provide evidence of protected effect of rosuvastatin for inflammation and oxidative damage. It will be of great interest to determine whether the correlation between PON1 and cytokines has any phenotypic effect on PON1.
