ABSTRACT
Objective To investigate the effect of Rhodiola on levels of inflammatory mediators and vascular endothelial function in rats with cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH).Methods Forty adult male SD rats were randomly divided into the sham operation group, model group, low-dose Rhodiola group, and high-dose Rhodiola group, with 10 rats in each group.Except for the sham operation group, rat models of CVS after SAH were established by cisterna magna twice method.1-5 d after modeling, the model group were treated with intraperitoneal injection of normal saline.The low-dose and high-dose Rhodiola groups were injected with 5mg/kg and 10mg/kg of Rhodiola respectively.5 days later, docking was performed and blood was collected to determine the levels of serum endothelin-1 (ET-1), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and cyclic guanosine monophosphate (cGMP).Then the rats were killed, and HE staining was performed to measure the diameter of basilar artery.The expression levels of basilar artery interleukin-6 (IL-6) mRNA, interleukin-1 β (IL-1 β) mRNA, vascular endothelial growth factor (VEGF) mRNA, endothelial nitric oxide synthase (eNOS), and inducible nitric oxide synthase (iNOS) were determined by real-time fluorescence quantitative polymerase chain reaction (RT-q-PCR).Results (1) The diameters of basilar arteries showed model group ＜ low-dose and high-dose groups ＜ the sham operation group (P ＜ 0.05).(2) The levels of ET-1, IL-6, TNF-α, IL-6 mR-NA, IL-1β mRNA and iNOS mRNA showed model group ＞ low-dose and high-dose Rhodiola groups ＞ the sham operation group while levels of cGMP, VEGF mRNA and eNOS mRNA showed model group ＜ low dose and high-dose Rhodiola groups ＜ the sham operation group (P ＜ 0.05).Conclusions Rhodiola can reduce the expressions of inflammatory reactions, improve the vascular endothelial function, and promote the expressions of vascular endothelial growth factor in rats with CVS after SAH.
ABSTRACT
Objective To investigate the levels of serum macrophage inflammatory protein-1α (MIP-1α),inflammatory factors and pulnonary function in patients with asthma,and the correlation between thenm.Methods Eighty patients with asthma were selected who were treated in our hospital from March 2015 to August 2016,and the data of 80 healthy adults were selected as control.The differences of serum MIP-1α,inflammatory factors,imnmunoglobulin and lung function were observed in two groups.The correlation between MIP-1α and inflammatory factors,lung function and immunoglobulin were analyzed.Results The levels of MIP-1α,interleukin (IL)-6,and tumor necrosis factor-α (TNF-α) in patients with asthma were significantly higher than those in control group (t =-207.04,-33.209,-55.132,P ＜ 0.01);The levels of forced vital capacity (FVC),the forced expiratory volume in one second (FEV1),FEV1/FVC,maximal mid expiratory flow (MMEF),and peak expiratory flow (PEF) in the asthma group were significantly lower than those in the control group (t =17.100,39.154,22.791,25.391,19.356,P ＜ 0.01).The IgG and IgM of asthma group were significantly lower than those of the control group (t =9.564,7.528,P ＜ 0.01).The IgE level was significantly higher than that of the control group (t =-82.683,P ＜0.01).The level of MIP-1α was positively correlated with the levels of IL-6,TNF-0 and IgE,and negatively correlated with FVC,FEV1,FEV1/FVC,MMEF,PEF,IgG and IgM in patients with asthma.Conclusions The level of serum MIP-1 α in asthmatic patients is high,and is closely related to the inflammatory cytokines and lung function in patients with asthma.
ABSTRACT
Objective To investigate the anti-inflammatory effects of low-dose and sustained release oral theophylline on the chronic obstructive pulmonary disease (COPD) patients.Methods Thirty four patients with stable COPD were randomly divided into two groups:theophylline group (n =18) was treated with slow-release theophylline (100 mg,twice daily),and placebo group (n =16) was given with placebo.Healthy non-smokers (n =12) were taken as control.The course of treatment was 12 weeks both of theophylline group and placebo group.The percentages of Neu/Leu and Mφ/Leu in sputum were detected before and after treatment and the concentrations of interleukin (IL)-17,IL-8,and tumor necrosis factor-α (TNF-et) were detected with enzyme linked immunosobent assay (ELISA).Results (1) Compared to pretreatment with theophylline group,the Neu/Leu was increased [(89 ±4.14)％ vs (83.4 ±6.98)％,P ＜0.05] and the Mφ/Leu was decreased [(6.4 ± 4.11) ％ vs (12.3 ± 6.96) ％,P ＜ 0.05] in the post-treated theophylline group.No significant changes in both Neu/Leu and Mφ/Leu were observed before and after placebo-treatment (P ＞ 0.05).(2) Compared to the control group,the concentrations of TNF-α,IL-8,and IL-17 in the sputum supernatant were significantly increased in both pretreatment and posttreatment with the theophylline or the placebo.Sputum TNF-α,IL-8,and IL-17 levels were significantly decreased in COPD patients who were given theophylline.Compared to pre-treatment with placebo group,the IL-8 and IL-17 levels were significantly increased in the post-treated placebo group (P ＜0.01).There was no significant change in TNF~ level between before and after treatment with the placebo.(3) The concentrations of IL-17,IL-8,and TNF-α in the sputum supernatant were positively correlated with the Neu/Leu counts (r =0.471,0.652,0.466,respectively,all P ＜0.01),negatively correlated with the forced expiratory volume in one second (FEV1 ％) (r =-0.516,-0.652,-0.496,respectively,all P ＜ 0.01).Conclusions Low-dose and sustained-release oral theophylline was efficient in improving airway inflammatory cells and inflammatory mediators,which plays an anti-inflammatory effect.
ABSTRACT
Objective To investigate the efficacy of ganciclovir in viral keratitis and its influence on serum related indicators.Methods Patients with viral keratitis from May 2012 to December 2013 in our hospital were randomly divided into control and observation groups, each group had 62 cases.Patients in control group were treated with acyclovir eye drops, and those in observation group were treated with ganci-clovir ophthalmic gel.The difference in efficacy of two groups was compared.The levels of serum inflamma-tory cytokines of interleukin-2 (IL-2), IL-4, IL-6, IL-8, tumor necrosis factor-α(TNF-α), and interferon-γ( IFN-γ) of two groups before and after treatment were compared, the serum levels of nitric oxide ( NO) , super oxide dismutase (SOD), malondialdehyde (MDA), C3, and C-reactive protein (CRP) were been compared.Results The pain relief time and corneal healing time of observation group [(3.41 ±0.89)d and (4.02 ±1.11)d] were all shorter than control group [(4.52 ±1.21)d and (6.30 ±1.45)d].The cure rate and total effective rate of observation group were 58.06%and 90.32%, respectively.It was sig-nificantly higher than control group ( P <0.05).After 3 and 7 days of treatment, the serum levels of IL-4, IL-6, and IL-8 were lower than control group, and IL-2, and IFN-γwere higher than control group (33.87%and 82.26%) ( P <0.05).After 3 and 7 days of treatment, the serum levels of NO and MDA were lower than control group, and SOD, C3, and CRP were higher than control group ( P <0.05).Con-clusions Ganciclovir has a better efficacy than acyclovir for viral keratitis, and can effectively adjust the serum levels of related indicators.
ABSTRACT
Objective Using the technology of siRNA to inhibit gene expression of T cells'nonreceptor tyrosine protein kinase Lck in asthmatic mice,and to study the effect of siRNA inhibited Lck to the function of T cells in asthmatic mice.Methods The 21 - 23 bp RNA fragments of mouse T cell Lck were made by chemosynthesis.INTERFERinTMsiRNA Transfection Reagent was used as transfection reagent to transfect the siRNA into the spleen T cells of asthmatic mice for 48 hours.Then T cells were mixed with bone marrow dendritic cells (DC) of asthmatic mice for another 48 hours.Cell culture suspension was collected and the level of IL-4,IL-13,IL-2,INF-γ were detected with respondent ELISA kits; Western Blot was used to identify if the expression of Lck was blocked.Results The expression of Lck in T cells almost could not be detected in siRNA interference group.The levels of IL-4 and IL-13 in siRNA interference group( 10.19 ± 1.66,12.34 ±0.79) were lower than no-siRNA interference(28.06 ±2.88,27.87 ± 1.61 )and control group ( 22.07 ± 2.5 1,20.47 ± 2.37 ),and the difference was statistical significant ( P ＜0.01 ).Conclusions Special siRNA could block the expression of special gene,and Lck specific siRNA could block the activation and differentiation of T cells and reduce the secretion of inflammatory cytokines in asthmatic mice.
ABSTRACT
Objective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05～0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323～0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.
