ABSTRACT
Objective To explore the correlation between the serum levels of interferon (IFN)-γ,interleukin (IL)-18,IL-10 and recurrent spontaneous abortion (RSA).Methods Enzyme-linked immunosorbent assay was used to detect the serum levels of IFN-γ,IL-18 and IL-10.There were 40 patients with RSA (RSA group) and 40 normal early pregnant women (control group) enrolled in this study.After 2 months,those serum cytokines in two groups of non-pregnant state were detected again.Results Compared to control group,the serum levels of IFN-γ and IL-18 of RSA group were significantly higher (P ＜0.01),the serum level of IL-10 was significantly lower (P ＜ 0.01).Two months after termination of pregnancy,there was no significant difference in the serum levels of IFN-γ and IL-10 between the two groups.The serum level of IL-18 maintained a high level in the RSA group after termination of pregnancy.Conclusions In patients with RSA,the serum levels of IFN-γ and IL-18 were elevated,the serum level of IL-10 was decreased.The serum levels of IFN-γ,IL-18 and IL-10 were closely related with RSA.
ABSTRACT
Objective To investigate whether hydrogen-rich saline could ameliorate the expressions of cytokines in a rat model of inflammatory pain through activating heme oxygenase-1 (HO-1).Methods Eighty male Sprague-Dawley (SD) rats,weighing 180 ～ 220 g,were randomly divided into five groups (n =16 in each group):Control group (Con),inflammation pain group (CFA),inflammation pain + hydrogen-rich saline group (CFA + H2),inflammation pain + HO-1 inhibitor Znpp-Ⅸ group (CFA + Znpp-Ⅸ),and inflammation pain + hydrogen-rich saline + HO-1inhibitor Znpp-Ⅸ group (CFA + H2 + Znpp-Ⅸ).The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were tested on days 1 (T1),2 (T2),3 (T3),5 (T4),7 (T5),and 14 (T6) after inflammation pain.The expressions of spinal HO-1 mRNA and protein were measured with real-time quantitative polymerase chain reaction (RT-PCR) and Western blot,and spinal inflammatory cytokines were measured with enzyme-linked immunosorbent assay (ELISA) on day 7 after inflammatory pain.Results Compared to Con group,MWT and TWL were significantly reduced;the spinal HO-1 mRNA level,protein expression and activity were increased;and the levels of tumor necrosis factor-α (TNF-α),interleukin (IL)-1β,IL-6 and IL-10 in spinal tissues were also increased in CFA group (P ＜ 0.05).Compared to CFA group,MWT and TWL were significantly increased;the spinal HO-1 mRNA level,protein expression and activity were further increased;and the levels of TNF-α,IL-1β and IL-6 were decreased,while IL-10 was further increased in CFA + H2group (P ＜ 0.05).Compared to CFA + H2 group,MWT and TWL were decreased;the spinal HO-1 mR-NA level,protein expression and activity were decreased;and the levels of TNF-α,IL-1β and IL-6 in spinal tissue were significantly increased,while IL-10 was decreased in CFA + H2 + Znpp-Ⅸ group (P ＜0.05).Conclusions Hydrogen-rich saline can ameliorate the mechanical and thermal allodynia in a rat model of inflammatory pain,and reduce the release of inflammatory cytokines via activating HO-1.
ABSTRACT
ObjectiveTo explore the changes of the frequency and cytokine production of CD19 + CD5 + B cells in Endometriosis before and after treatment.MethodsFlow cytometry and quantitative PCR were used to assess the frequency,cytokine expression of CD19 + CD5 + B cells in the peripheral blood,peritoneal fluids and endometrium biopsies of 35 patients with Endometriosis and 29 patients with myoma of uterus (control subjects).Changes in the CD19+ CD5+ B cell compartment in the peripheral blood were compared before and after treatment.ResultsAll 35 endometriosis patients had higher frequencies(all P ＜0.01 ) of CD19+ CD5 + B cells in the peripheral blood,peritoneal fluids and endometrium biopsies [ (13.1 ± 1.9)％,(12.1 ±2.0)％,(11.7 ± 1.7)％] than 29 control subjects[ (2.9 ±0.8)％,(2.6 ±0.9)％,(2.8 ±1.1 )％ ].CD19 + CD5+ B cells from endometriosis patients expressed higher IFN-γ[ (7.2 ± 1.0) × 103,(7.9±1.3) ×103,(7.4±1.1) ×103 copies] than control subjects [ (1.9±0.7)×103,(2.2±0.8)×103,(2.0 ±0.5) × 103 copies).The endometriosis patients also had higher IL-10 production of CD19 + CD5 + B cells [ (6.4 ±0.9) × 103,(6.8 ± 1.2) × 103,(6.1 ±0.8) × 103 copies] than control subjects [ ( 1.7 ±0.5) × 103,(2.1 ±0.9) × 103,( 1.6 ±0.4) × 103 copies].Compared with control subjects,the endometriosis patients had a clinical response to treatment demomtrated a significant decrease in CD19 + CD5 + B cells in the peripheral blood[ ( 13.1 ± 1.9)％ vs (7.3 ± 1.2)％ ],expressed lower IFN-γ [ (7.2 ± 1.0)×103 copies vs (3.3 ±0.6) × 103 copies],produced less IL-10 [(6.4 ±0.9) × 103 copies vs (3.2 ±0.7) × 103 copies].ConclusionsCD19+ CD5 + B cells might play an important role in the pathogenesis of endometriosis through higher IFN-γand IL-10 expression.
ABSTRACT
Objective To investigate the relationship among the concentration of plasma interleukin (IL)-10 and plasma IL-13 and the clinical therapeutic effect in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods Thirty-six AECOPD inpatients were enrolled in this study.Blood samples of the subjects were collected as soon as hospitalization, and plasma IL-10 and IL-13concentrations were analyzed by enzyme-linked immunosorbent assay.The clinical manifestations of subjects were quantified by a special designed score standard, and were evaluated at the time points of hospitalization, 48 hours treatment and 96 hours treatment.The therapeutic effect was evaluated by clinical manifestations score combined with pulmonary ventilation functional parameter.Eventually, the correlation among the concentration of IL-10 concentration and IL-13 and the clinical therapeutic effect were analyzed.Results The correlation coefficients between clinical manifestations score decrease and pulmonary ventilation function improvement with plasma IL-10 concentration after 48 hours treatment were 0.85 and 0.48 respectively,then, 0.64 and 0.52 after 96 hours treatment.The correlation coefficients between clinical manifestations score decrease and pulmonary ventilation function improvement with plasma IL-13 concentration after 48hours treatment were -0.41 and -0.34, after 96 hours treatment , correlation coefficients between clinical manifestations score decrease with plasma IL-13 concentration was -0.36.All of the above correlation coefficients were statistically significant.Conclusion Plasma IL-10 concentration was positively, whereas, IL-13 concentration was negatively correlated with the therapeutic effect in AECOPD patients.
