RESUMEN
Objective To study the relationship of CSF and serum FGF-2 level with clinical parameters in MND patients.Methods Ninety-one MND patients served as a MND group and 40 noninflammtory nervous system disease patients served as a control group.Their CSF and serum FGF-2 level were measured by ELISA.The neurological deficit in ALS patients was assessed according to the modified ALSFRS-r,the progression of MND was assessed according to the DPR.The ALS patients were followed up,during which their survival time was recorded.Results The serum FGF-2 level was significantly higher in MND group than in control group (P＜0.01).The CSF,FGF-2 level were significantly higher in ALS patients of MND group than in those of control group (319.2±105.9 ng/L vs 241.7±34.3 ng/L,P＜0.01).The CSF and serum FGF-2 level were positively correlated with the duration of MND and negatively correlated with the DRP in ALS patients (P＜0.01).Survival analysis of MND patients indicated that the survival time of PMA patients was longer than that of PLS,ALS and PBP patients (P=0.000).The cumulative survival rate of ALS patients with a high serum FGF-2 level was significantly higher than that of those with a low serum FGF-2 level (P=0.002).Conclusion The CSF and serum FGF-2 level are higher in some MND patients and can be used as one of the biomarkers for evaluating the progression and predicting surrival.
RESUMEN
Objective To study the clinical significance of serum hs-CRP level in smokers with carotid atherosclerosis (CA) and analyze its difference in subtypes of CA.Methods Two hundred and ninety-eight smokers with CA served as a smoker group and 120 non-smokers with CA served as a non-smoker group,50 healthy smokers without CA served as control group 1 and 50 healthy non-smokers served as control group 2.Their serum hs-CRP level was measured by colloid-enhanced immunoturbidimetry.Smokers were divided into stable plaque group and unstable plaque group.Effect of smoking on serum hs-CRP level in CA patients was analyzed.Results The serum hs-CRP level was significantly higher in smoker group and control group 1 than in non-smoker group and control group 2 (7.26±4.24 mg/L vs 3.56±2.28 mg/L,4.34±2.74 mg/L vs 3.17± 1.68 mg/L,P＜0.05).The smoking index was positively related with the serum hs-CRP level (r=0.395,P＜0.01).The number of daily smoked cigarettes was significantly greater in unstable plaque group than in stable plaque group (P＜0.05).The recurrence rate of ischemic stroke was significantly higher in smokers with a high serum hs-CRP level than in those with a low serum hs-CRP level (11.36％ vs 2.00％,P＜0.01).Conclusion Smoking can increase the serum hs-CRP level in CA patients,which is closely related with the stability of plaques and the recurrence of ischemic stroke.
RESUMEN
Objective To analyze the correlation of plasma homocysteine (Hcy) level with hemodynamic parameters and high density lipoprotein cholesterol (HDL-C) level in patients with lacunar infarction and its significance in lacunar infarction.Methods Transcranial Doppler examination was performed in 120 patients with lacunar infarction admitted to our hospital from February 2012 to March 2013 and 100 healthy controls; systolic flow velocity (SFV),distalotic flow velocity (DFV),mean flow velocity (MFV) and pulsatility index (PI) were assessed at the middle cerebral artery (MCA) and basilar artery (BA).Serum creatinine,total cholesterol,triglycerides,HDL-C,and low-densitylipoprotein cholesterol (LDL-C) levels were detected using enzymatic colorimetric method.Plasma Hcy level was measured by circulating enzymatic method.Results Blood flow velocity indexes,such as SFV,DFV,MFV and PI in the MCA of lacunar cerebral infarction patients,were significantly higher than those in their BA and the MCA blood of control group,with statistically significant differences (P＜0.05); blood flow velocity indexes,such as MFV and PI in the BA of lacunar cerebral infarction patients,were higher than those in the BA of the control group,with significant differences (P＜0.05).Lacunar cerebral infarction patients had significantly higher levels of Hcy,total cholesterol,LDL-C,tdglycerides,and HDL-C as compared with control group,with statistical differences (P＜0.05).Linear correlation analysis showed that PI of MCA and BA and Hcy level were positively correlated in lacunar infarction patients (r=0.530,P=0.020; r=0.450,P=0.010); and HDL-C and Hcy levels had negative correlation (r=-0.308,P=0.010).Conclusion A significant association between plasma Hcy and PI of cerebral arteries and serum HDL-C level indicates that Hcy plays a role in the increase of distal arterial resistance in lacunar infarction.
RESUMEN
Objective To study the cause of placental abruption and relationship of outcomes of different clinical types of placental abruption.Methods 35 patients with placental abruption hospitalized were retrospectively analyzed. Results The incidence of placental abruption was 0. 3％. The rate of type Ⅰ was 60. 0％ (21cases) ,type Ⅱ 31.4％ ( 11 cases) and type Ⅲ 8. 6％ ( 3 cases). The gestational hypertension was the main cause of placental abruption. The rate of antepartum ultrasonic diagnostic was 40. 0％. The cesarean section rate was 71.4％. The incidence of postpartum hemorrhage, uteroplacental apoplexy and shock, DIC and partial hysterectomy on uterus were 22. 8％ (8 cases) ,8.6％ (3 cases) and 8.6％ (3 cases) ,respectively. The mortality rate of perinatal newborn was 14. 3％ (5 cases). Conclusion The gestational hypertension was the main cause of placental abruption. There was close relationship between the degree of placental abruption and different pregnant outcomes of women.
