RESUMO

Objective To investigate the relationship between high sensitive C reactive protein(hsCRP) and monocyte chemotactic protein-1 (MCP-1) in patients with metabolic syndrome(MS).Methods Sixty-two patients with MS and 52 normal healthy individuals (NS) were recruited in the study.And the levels of hs-CRP and MCP-1 were detected by ELISA.The severity of Insulin resistance was calculated by homeostasismodel assessment of insulin resistance(HOMA-IR).The monocytes in blood were isolated,cultured and stimulated by different concentrations of CRP.MCP-lexpression of monocytes was measured by real-time PCR.Results Patients with MS displayed significantly higher serum levels of hs-CRP and MCP-1 compared with healthy control group [(80.26 ±35.52) nmol/L vs (3.12 ±2.55) nmol/L for hs-CRP,P <0.01 ; (15.35 ± 10.12) nmol/L vs (9.76 ± 6.15) nmol/L for MCP-1,P < 0.05].There was significantly positive correlation between hs-CRP and MCP-1.Serum hs-CRP,MCP-1and insulin resistance index were positively correlated,respectively.In vitro experiments indicated that CRP could up-regulate MCP-1 expression of monocytes in a concentration-dependent way.When the concentration of CRP was 176nmol/L,the expression of MCP-1 could reach 105% compared with non-stimulated group.Conclusion With the severity of the inflammatory response and enhanced insulin resistance,elevated serum CRP level may result in MCP-1 expression in patients with metabolic syndrome.

RESUMO

OBJECTIVE: To examine if amniotic fluid (AF) monocyte chemotactic protein-1 (MCP-1) concentrations are useful in the identification of intrauterine infection and pregnancy outcomes in preterm labor with intact membranes. METHODS: The study population consists of 65 patients who received amniocentesis for preterm labor with intact membranes. Amniotic fluid was cultured for aerobic and anaerobic bacteria, as well as mycoplasmas. MCP-1 was determined by a sensitive and specific immunoassay. Fisher's exact test, Mann-Whitney U test, receiver operating characteristic curve, survival techniques, logistic regression, and Spearman correlation were used for statistical analysis. RESULTS: (1) Patients with a positive amniotic fluid culture had a significantly higher median AF MCP-1 concentration than those with negative results (median, 9.0 ng/mL; range, 0.45-40.5 ng/mL; vs median, 0.82 ng/mL; range, 0.06-30.1 ng/mL; P1.9 ng/mL had a significantly shorter median interval to delivery, the higher rate of histologic chorioamnionitis, preterm delivery within 2 and 5 days, and the occurrence of congenital proven or suspected sepsis than did those with AF MCP-1 concentration of <1.9 ng/mL after adjustment for gestational age (P<.05). (3) There was strong correlation between AF MCP-1 concentrations and AF interleukin-6 concentrations (r=.881, P<.001). CONCLUSION: AF MCP-1 determinations are useful in the identification of intrauterine infection, preterm delivery, and neonatal infectious complication in preterm labor with intact membranes.

RESUMO

Aim To observe the effect of mycophenolate mofetil(MMF) on expressions of MCP-1 and CD68 in renal tubulointerstitial injury of diabetic rats and explore the mechanism of MMF′s protective role.Methods Diabetes was induced in uninephrectomized male Wistar rats by peritoneal injection of STZ (65 mg?kg-1). Rats were randomly divided into three groups:control group (NC),diabetic group (DM) and treated group (DM+MMF) with MMF(15 mg?kg-1?d-1).This study lasted for 8 weeks. 24 h urinary protein,blood glucose and the ratio of left kidney weight/body weight were determined after 8 weeks.The renal tubulointerstitial morphological change was observed,immunohistochemical method was used to analyze expressions of MCP-1 protein and CD68. Expression of MCP-1 mRNA in renal tissue was measured by quantitative Real-time PCR.Results Compared with NC group, serum glucose level,24 hour urinary protein and the ratio of left kidney weight/body weight were significantly increased(P
