Relationship between serum indexes,pathogenetic condition and prognosis in patients with acute ischemic stroke / 天津医药

Objective To discuss the relationship between serum lipoprotein-associated phospholipase A2(Lp-PLA2),low-density lipoprotein(LDL),amyloid beta 1-42(Aβ1-42)and soluble intercellular adhesion molecule-1(sICAM-1)levels,the National Institutes of Health Stroke Scale(NIHSS)score and prognosis in patients with acute ischemic stroke(AIS).Methods A total of 106 patients with AIS who underwent intravenous thrombolysis(the thrombolysis group),30 AIS patients without thrombolysis(the non-thrombolysis group)and 95 healthy individuals(the control group)were included in the study.The thrombolysis group was divided into the recanalization group(n=41)and the non-recanalization group(n=65)according to whether the vein was recanalized after thrombolysis.Patients were divided into the mild group(n=45),the moderate group(n=36)and the severe group(n=25)based on the NIHSS score.They were divided into the good prognosis group(n=65)and the poor prognosis group(n=41)based on the modified Rankin Scale(mRS)score.Serum levels of four indexes in different groups were compared.Their relationship with the NIHSS score and the prognosis was analyzed.Results The vein recanalization rate in 106 patients with thrombolysis was 38.68%(41/106).Serum Lp-PLA2,LDL,Aβ1-42 and sICAM-1 levels were lower in the recanalization group than those in the non-canalization group(P＜0.05).Serum Lp-PLA2,LDL,Aβ1-42 and sICAM-1 levels increased successively in the control group,the thrombolysis group and the non-thrombolysis group(P＜0.05).The 4 serum indexes increased with the aggravation of disease condition,and were positively correlated with NIHSS score(P＜0.05).High serum levels of Lp-PLA2,LDL,Aβ1-42 and sICAM-1 were risk factors for poor prognosis of patients with thrombolysis(P＜0.05).The area under the curve(AUC)and specificity of the combination of 4 serum indexes for predicting poor prognosis of patients with thrombolysis were higher than those of prediction with single index(P＜0.05).Conclusion The expression levels of serum Lp-PLA2,LDL,Aβ1-42 and sICAM-1 in patients with AIS are high.They can be used as important reference indexes for disease condition monitoring and prognosis evaluation.

Protective effect of sevoflurane preconditioning on lung ischemia-reperfusion injury in rats and its influence on TLR4/MyD88/NF-κB signaling pathway / 器官移植

Objective To evaluate the protective effect of sevoflurane preconditioning on lung ischemia-reperfusion injury (IRI) and its influence on the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor (NF)-κB signaling pathway. Methods Forty healthy adult SD rats were randomly divided into the control group (Sham group), lung IRI model group (LIRI group), sevoflurane group (Sev group) and TLR4 inhibitor TAK-242 combined with sevoflurane group (TAK+Sev group), 10 rats in each group. The pathological changes of lung tissues were observed by hematoxylin-eosin (HE) staining and the pathological injury score was graded. The cell apoptosis of lung tissues was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick- end labeling (TUNEL) and the apoptosis rate was calculated. The wet-to-dry (W/D) ratio of lung tissues was measured to determine the water content of lung tissues. The levels of oxidative stress-related parameters in the lung tissues and inflammatory factors in both the lung tissues and serum were detected. The expression levels of TLR4/MyD88/NF-κB signaling pathway-associated proteins in the lung tissues were determined by Western blot. Results Compared with the Sham group, the pathological injury score, W/D ratio, cell apoptosis rate, malondialdehyde (MDA) level, inflammatory factor level and the relative expression levels of TLR4, MyD88 and NF-κB p65 proteins in the lung tissues were significantly increased, whereas the superoxide dismutase (SOD) level and the relative expression level of NF-κB inhibitory protein α(IκBα) were significantly decreased in the LIRI and Sev groups (all P < 0.05). Compared with the LIRI group, the pathological injury score, W/D ratio, cell apoptosis rate, MDA level, inflammatory factor level and the relative expression levels of TLR4, MyD88 and NF-κB p65 proteins were significantly decreased, whereas the SOD level and the relative expression level of IκBα were significantly increased in the Sev and TAK+Sev groups (all P < 0.05). Compared with the Sev group, the pathological injury score, W/D ratio, cell apoptosis rate, MDA level, inflammatory factor level and the relative expression levels of TLR4, MyD88, NF-κB p65 proteins were significantly decreased, while the relative expression level of IκBα was significantly increased in the TAK+Sev group (all P < 0.05). Conclusions Sevoflurane preconditioning may inhibit the activation of TLR4/MyD88/NF-κB signaling pathway and suppress inflammatory reaction and oxidative stress, thereby effectively mitigating the lung IRI.

ObjectiveTo investigate the effects of alpha-lipoic acid on serum soluble intercellular adhesion molecule-1 (sICAM-1) and high sensitive-C reactive protein (hs-CRP) levels in patients with early diabetic nephropathy (DN).MethodsA total of 61 patients with early DN were randomized into treatment group (n =31 ) and control group ( n =30 ).The two groups were both treated with dietary control and oral hypoglycemic drugs or insulin.Meanwhile,the treatment group was additionally given alpha-lipoic acid 300 mg/d by intravenous infusion for 20 days.The levels of sICAM-1 and hs-CRP in each group were detected.Results The levels of sICAM-1 and hs-CRP were decreased significantly in alpha-lipoic acid treatment group after 20 days of therapy ( [ 198.03 ±23.67] μg/L vs [271.17 ±34.66] μg/L,[5.16 ±0.43] mg/Lvs [7.95 ±0.88]mg/L,P ＜0.01 ).Conclusion alpha-lipoic acid may decrease the expression of slCAM-1 and hs-CRP,and that may be one of the mechanisms to postpone the progress of early DN.

The effects of mycophenolate mofetil on immunologic compromise in rats with severe acute pancreatitis / 中华急诊医学杂志

Objective To observe the modulatory effects of NF-κB on dynamic changes of TNF-α、IL-1β and ICAM-1 in rats with severe acute pancreatitis (SAP),and to assess the effects of pretreatment with mycophenolate mofetil (MMF) on them.Methods A total of 104 male Wistar rats were randomly divided into normal group,sham operation group,SAP group and MMF group.(1) In normal group,rats had just an incision on abdomen wall and sutured (n =8) ; (2) In sham operation group,rats underwent laparotomy with flipping over the pancreas and gendy striking five times by using blunt instrument and abdomen was closed (n =32); (3) In SAP group,SAP in rats was induced by the retrograde injection of sodium taurocholate (STC) into the pancreatic duct (n =32) ; (4) In MMF group,MMF (250mg/kg)was injected intraperitoneally one hours after injection of STC (n =32).Rats were saerificed by abdominalaorta exsanguination separately at intervals of 3,6,12 and 24 h after modeling of pancreatitis.Histologic score of pancreatic tissue was assessed,and serum amylase (AMS) and serum C-reactive protein (CRP)were measured by automatic biochemical detector.The serum levels of inflammatory cyctokines (TNF-α,1L-1β and 1CAM-1 ) were measured by using ELISA,and expression of NF-κB mRNA in pancreatic tissue was measured by using quantitative PCR.Results Compared with sham operation group,histologic score of pancreatic tissue,serum amylase,TNF-α、IL-1β and ICAM-1 in SAP group were increased significantly (P ＜ 0.05 ).Pretreatment with MMF obviously deceased histologic score,and the serum levels of amylase,TNF-α,IL-1β and ICAM-1 and the expression of NF-κB mRNA were higher than those in SAP group in early stage (P ＜0.05 ).Conclusions Cytokines play an important role in early stage of SAP.MMF could attenuate the severity of inflammatory response through inhibiting cellular immunity and modulating the proinflammatory cytokines produced.

Immune effect of propylthiouracil and methimazole in the treatment of Graves' disease / 中华内分泌代谢杂志

ObjectiveTo observe the changes in TSH receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) levels after treatment of propylthiouracil ( PTU ) and methimazole( MMI ) in patients with Graves' disease (GD). MethodsOne hundred and six cases of clinically diagnosed patients with GD were divided into PTU and MMI groups( each group, n =53 ). The patients in two groups were regularly followed for 36 months. TRAb and sICAM-1 were measured with ELISA method. Results( 1 ) The general data of two groups were not significantly different before treatment( all P＞0. 05 ). ( 2 ) There was no difference in TRAb positive rates between two groups before treatment. The clinical remission rates between PTU and MMI groups showed no difference (83.02％ vs88.68％ ). The cure rate was higher in MMI group than in PTU group( 58.49％ vs 37.74％, P＜ 0. 05 ). (3) There existed significant differences in TRAb levels determined before and 6, 12, 24,30, and 36 months after treatment( all P＜0. 01 ), being gradually decreased with time( F=275.48 ,P＜0.01 ). TRAb levels between two groups were significantly different( F=5.86, P＜0. 05 ). (4) sICAM-1 levels at 36 months after treatment compared with the baseline in both groups were statistically different (P＜0. 01 ), but no difference was found between two groups.ConclusionsBoth PTU and MMI improve the immune status of patients with GD,and the immunosuppressive effect of methimazole is more evident.

Association of hyaluronic acid and soluble intercellular adhesion molecule-1 with the activity of Graves' ophthalmopathy / 中华内分泌代谢杂志

To investigate weather serum soluble intercellular adhesion molecule-1 (sICAM-1) and hyaluronic acid(HA) levels can be used in assessing the disease activity of Graves' ophthalmopathy (GO).Serum levels of sICAM-1 and HA were determined in 48 cases with GO and 30 cases with Graves' disease without GO (CON).Compared with the CON group,the levels of sICAM-1 and HA in GO cases were raised significantly( P＜0.05 ).sICAM-1 and HA levels in the subgroup of patients with active GO were markedly elevated when compared to those with stable GO(P＜0.05 ).Pearson regression analysis showed that elevated levels of slCAM-1 and HA were positively correlated with the Clinical Activity Score ( CAS ) of GO ( r =0.53,P ＜ 0.01 ; r =0.46,P ＜ 0.01 ) ; A significant correlation between sICAM-1 and HA( r=0.31,P＜0.05 ) was noted.The raised serum levels of sICAM-1and HA may serve as two activity markers of GO.

The significance of changes in thyrotropin receptor antibody and soluble intercellular adhesion molecule-1 levels in patients with thyroid-associated ophthalmopathy during intravenous methylprednisolone pulse treatment / 中华内分泌代谢杂志

Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P＜0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.
