Objective To explore the mechanism of the acute cerebral infarction leading to systemic inflammatory response syndrome (SIRS) which causes multiple organ dysfunction syndrome (MODS), and to explore the role of tumor necrosis factor (TNF-?) and IL-1? in the mechanism from SIRS to MODS.Methods 68 cases of acute cerebral infarction (ACI) were divided into three groups. They were 36 cases of simple acute cerebral infarction (SACI group), 32 cases accompanied with SIRS (SIRS group) and 24 cases accompanied with MODS (MODS group). Enzyme linked immunosorbent assay (ELISA) method was used to measure serum TNF-? and IL-1? contents at different time after ACI and compared with 28 healthy persons.Results (1) 47.06% of the 68 cases were accompanied with SIRS, of whom 75.00% were accompanied with MODS.(2) The serum TNF-? and IL-1? levels were the highest in MODS group, next in SIRS group, then in SACI group, the lowest in control group. The differences were significant among 4 groups (all P

Objective To explore the possible mechanism of acute cerebral hemorrhage with systemic inflammatory response syndrome (SIRS) which caused multiple organ dysfunction syndrome (MODS), and to investigate the significance of serum nitric oxide (NO) and nitric oxide synthase (NOS) in the development of acute cerebral hemorrhage from SIRS to MODS.Methods The incidence rate of acute cerebral hemorrhage leading to SIRS and MODS was investigated. Serum NO and NOS levels in 73 patients with acute cerebral hemorrhage were detected dynamically by nitratase and chromometry methods. 20 normal healthy people were adopted as control group.Results The incidence rate of cerebral hemorrhage accompanied with SIRS was 47.95%(35/73),74.29%(26/35) of which leaded to MODS. 73 patients serum NO and NOS levels were elevated obviously, and the differences were significant compared with control group (all P

Objective To explore the risk factors of earlier neurological function deterioration in acute cerebral infarction patient.Methods 157 cases with acute cerebral infarction had been studied,including the patient's history,general syndromes,clinical characteristic,CT or MRI and laboratory test.Multivarivate noncondition stepwise Logistic model analysis was made after single variable analysis.Results There were 58 patients with neurological function deterioration in 157 cases acute cerebral infarction patient.The morbidity was 36.3%.The following nine factors were associated with earlier neurological function deterioration in acute cerebral infarction i.e. the history of hypertension and diabetes,CT or MRI abnormal,higher WBC count,fever,higher blood sugar,lover mean arterial press,higher fibrin,higher serum Fe-protein;But age,sex,weight,the history of drink and smoker,blood lipemia lever were associated with the disease.Conclusion Earlier neurological function deterioration in acute cerebral infarction patient is caused by multiple factors.Singer test is not easy to calculate the result.To analyze generally patient's clinical material may calculate if earlier neurological function deterioration in acute cerebral infarction patient takes place.

Objective To investigate the change of serum C-reactive protein(CRP) levels in patients with acute cerebral infarction(ACI) and ACI with multiple organ dysfunction syndrome(MODS), and the relationship between serum CRP levels and incidence of MODS.Methods The serum CRP levels of 30 normal healthy people and 82 patients with ACI were detected by immune transmission turbidity method. The data from the patients with lacunar cerebral infarction(LCI), acute simple cerebral infarction(PACI) and ACI with MODS(ACI+MODS) were compared.Results The levels of serum CRP in patients with ACI significantly increased compared with the controls( P

Objective To investigate the degree of cognitive impairment and its clinical significance of Binswanger's disease(BD),leukoaraiosis(LA) and LA with cerebral infarction(LA+CI).Methods Mini-mental state examination(MMSE) and clinical memory scale (CMS) were used to evaluate the cognitive impairment in 33 patients with BD, 27 patients with LA, 31 patients with LA+CI and 30 healthy controls.Results (1)The scores of MMSE and CMS in BD group, LA group, LA+CI group were significantly lower than those in healthy control group( P

Objective To study the role of serum C-reactive protein (CRP) ,supplement C3 and CA in sys-temic inflammatory response syndrome (SIRS) induced by acute cerebral infarction(ACI).Methods The levels of CRP,C3 and CA were measured by automatic immunoturbidimetry in 52 ACI cases accompanied with SIRS (SIRS group) ,50 cases of acute simple cerebral infarction(SACI group) and 46 normal cases (control group).Results The serum CRP, C3 ,and CA levels were significantly different among the three groups( F=720.6,580.8,94.1 ,P <0.01) ,the serum CRP levels in SIRS group were significantly higher than those in SACI group(P <0.01 ).The ser-um C3 and CA levels in SIRS were significantly lower than those in SACI group(P <0.01).With the diagnosis crite-rion items increasing, the serum CRP levels tended to be higher (t = 7.69 ,P < 0.01 ), and the serum C3, CA levels tended to be lower meeting SIRS diagnosis criterion numbers increasing respectively (t=10.68 and 10.53, P <0.01).Conclusion The serum ClIP levels are higher significantly and the serum levels of C3 and C4 are lower sig-nificantly when ACI progresses to SIRS.The serum CRP,C3,CA level changes can be used as an index for judging the progress of ACI progressed to SIRS.

Objective To investigate the changes of serum endotoxin and its receptor CD 14 gene expression in multiple organs in models of acute forebrain ischemia complicated with multiple organ dysfunction syndrome (MODS), and the pathogenesis of cerebrogenic multiple organ dysfunction syndrome (CMODS). Methods 54 Wistar rats were randomly divided into normal control group ( n=6), sham-operative group ( n=8) and forebrain ischemic group ( n=40). The rats in forebrain ischemic group were randomly divided into 5 subgroups: 12, 24, 36, 48, and 72 h (8 rats in each group). The contents of endotoxin in plasma were determined after models of acute forebrain infarction established. The area density and optical density of positive staining expressing CD 14mRNA in lung, liver, intestine and kidney were analyzed for the relative content of CD 14mRNA using in situ hybridization and CMIA medical image analysis system.Results Plasma endotoxin level was markedly high at 12 hours after acute forebrain ischemia, peaked at 24 hours and somewhat decreased at 72 hours. The CD 14mRNA expression in lung, liver, intestine, and kidney tissues increased after brain ischemia, reached the peak at 24~36 h, and decreased after 48 hours. The highest change of CD 14mRNA expression was found in lung ( P
