ObjectiveToinvestigatetheroleofimmuneinflammatoryreactionintheformationof intracranial aneurysm. Methods The intracranial aneurysms in 40 patients of craniotomy ( intracranial aneurysm group) and the vascular specimens in 20 craniotomy patients w ith traumatic brain injury (control group) w ere col ected. Fluorescence quantitative polymerase chain reaction w as used to detect the expression of interleukin (IL)-17 receptor in the arterial w al . Flow cytometry w as used to detect the Th-17 cel s in peripheral blood. Enzyme-linked immunosorbent assay w as used to measure the levels of IL-17, IL-6 in the arterial w al and tumor necrosis factor-α( TNF-α) in peripheral blood. Results There w ere no significant differences in the age (62.6 ±8.7 years vs.61.4 ±7.9 years;t=0.342;P=0.681), proportions of male (60.0%vs.65.0%; χ2 =0.246, P=0.434), hypertension ( 12.5%vs.10.0%; χ2 =0.315, P=0.492), diabetes (75.0%vs.10.0%; χ2 =0.284, P=0.482), and smoking (35.5%vs.30.0%; χ2 =0.224, P=0.413) betw een the intracranial aneurysms group and the control group. The expression of IL -17 receptor in the arterial w al (0.106 ±0.032 vs.0.264 ±0.071; t=5.115, P=0.001) and the proportion of Th17 cels in peripheral blood (2.75%±0.53%vs.7.18%±1.54%; t=8.436, P<0.001) and IL-17 level ( 7.32 ±1.82 μg/L vs.22.64 ±4.51 μg/L; t= 8.357, P< 0.001 ) in the control group w ere significantly low er than those in the intracranial aneurysm group. The levels of IL-6 (1.15 ±0.24 μg/L vs. 19.64 ±4.16 μg/L; t=9.527, P<0.001) and TNF-α(1.43 ±0.31 μg/L vs.26.17 ±4.32 μg/L; t=9.816, P<0.001) in the arterial wal in the control group were significantly lower than those in the intracranial aneurysm group. Conclusions The expression of IL-17 receptor in the arterial w al , the proportion of the Th17 cels and IL-17 level in peripheral blood were increased in patients with intracranial aneurysms. Immune inflammation may be involved in the formation of intracranial aneurysm.
ABSTRACT
@#Objective To investigate the effect of Puerarin on expression of C-reactive protein(CRP)in iliac artery of atherosclerotic rabbits.Methods Twenty male New Zealand white rabbits were divided into the normal control group(n=6,fed on a normal diet),basic control group(n=8,fed on a cholesterol diet)and Puerarin group(n=8,fed on a cholesterol diet).The balloon injury of iliac arteries was performed in animals of the basic control group and Puerarin group,and the animals of the Puerarin group were injected with Puerarin(25 mg/kg/d per rabbit)after injury.Four weeks after balloon injury,untreated and balloon injury iliac arteries were harvested for immunocytochemical staining.The mRNA and protein expression of CRP were tested by RT-PCR and immunucytochemistry.Results The mRNA and expression of CRP in atheroseclerotic plaque of iliac artery in the Puerarin group was significantly lower than that in the basic control group(P<0.01).Conclusion Puerarin can make atheroseclerotic plaque stable by regulating of the expression of CRP in iliac artery of atherosclerotic rabbit.
ABSTRACT
@#ObjectiveTo investigate the effects of Shenmai Injection(SI) on chronic systolic heart failure patients.Methods120 chronic heart failure patients were randomly divided into routine treatment and the routine treatment and SI group. The changes of angiotension Ⅱ(Ang Ⅱ), aldosterone(Ald), endothelin-1 (ET-1), interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α), plasm rennin activity (PRA), cardionatrin(ANP), brain natriuretic peptide (BNP), cardiac function were observed.ResultsAfter treatment, LVEF,stage of NYHA increased in two groups,LVDs, LVDd and the level of Ang Ⅱ,Ald, ET-1, IL-6, TNF-α,PRA, ANP and BNP decreased in both groups(P<0.05). LVEF, stage of NYHA in the routine treatment and SI group incresed more significantly than those in routine treatment group(P<0.05). LVEDs, LVEDd and the level of Ang Ⅱ,Ald, ET-1, IL-6, TNF-α,PRA, ANP and BNP in the routine treatment and SI group were decreased more significantly than those in routine treatment group (P<0.05).ConclusionSI can improve not only the disturbed endocrine function and cytokines, but also left ventricular function.
ABSTRACT
Objective:To investigate the effect of heat shock protein 60(HSP60) on the functions of dendritic cells of ApoE-/-mice (mDCs) in vitro by signal transduction of mitogen-activated protein kinase (MAPK) family mediated by Toll-like receptors (TLRs).Methods:Myeloid mDCs were extracted in vitro from ApoE-/-mouse marrow,which were incubated as atherosclerotic animal model,and divided into three groups:HSP group,LPS group and control group.The three groups of mDCs were incubated to mature with mHSP60,LPS and normal saline,respectively and then examined the expression of TLR protein and mRNA by flow cytometry and real-time RT-PCR.In addition,the expression level of CD80 was examined by flow cytometry.The expression of MAPK family proteins was determined by Western blot analysis.The levels of cytokines secreted by mDCs,such as IL-6 and TNF-?,were analyzed by ELISA.Results:The expression of TLRs and MAPK families (p38 and ERK) was increased in the samples of HSP group,when compared with control group (P0.05).Conclusion:HSP60 is involved in activation of mDCs of atherosclerotic animal model by means of the signal transduction of MAPK family mediated by TLRs.
