OBJECTIVE:To study the effect of broad-spectrum antibiotics on coagulation function in patients with cerebrovascular disease. METHODS:10 cases of coagulation dysfunction in patients treated with broad-spectrum antibiotics were colleted and analyzed in respects of PLT amount,PT,INR and clinical hemorrhage manifestations before and after treatment. RESULTS:After treatment,10 cases showed significant decreased amount of PLT;3 cases showed prolongation of PT,INR. CONCLUSION:The effect of antibiotics on coagulation function in patients with cerebrovascular disease partly associates with many factors e.g. drug combination and characterize with individual difference and sensitivity.

Objective To prepare the recombination protein and polyclonal antibodies against human apolipoprotein A5(ApoA5)and detect the expression of ApoA5 in human tissues with the antibody,then further study the fuction and serum level of ApoA5.Methods With PCR and gene recombinated techniques,the prokaryotic ApoA5 expression vector was constructed.The His-ApoA5 fusion protein was expressed in E.ColiM15,and the fusion protein was injected into New Zealand rabbits to prepare polyclonal antibody.The antibody was tested for their specificity with ELISA and Western-blot,then it was used to detect the tissue distribution of ApoA5.Results It was found that there was a specific brand at 40 ku of the recombination ApoA5(rApoA5);the polyclonal antibody had high immunoreactivity and specificity.ApoA5 was expressed in human sera and hepatic tissue,not in other tissues(heart,vessel,spleen,intestine and lung),regardless of the lipid level.Conclusion The pQE30-ApoA5 is constructed successfully,the rApoA5 can be expressed in E.Coli M15;ApoA5 antibody has highly specifity.It can be used in clinical test.There is ApoA5 in human serum,and ApoA5 is expressed in liver which may be significant in lipid metabolism.

Objective To study the relationship between velocity of middle cerebral artery(MCA),severity of disease and watershed infarction(WSI) in patients with extracranial internal carotid artery(EICA) stenosis or occlusion.Methods Transcranial Doppler(TCD) was used to detect the mean velocity(MV) of MCA in 120 patients with EICA stenosis or occlusion.The National Institutes of Health Stroke Scale(NIHSS) was used to evaluated the patients′ condition.And CT or MRI was used to diagnosised the WSI.Results MV of MCA was severe reduced in 10 cases,middle reduced in 38 cases,and mild reduced in 42 cases,while there were 30 cases with normal MV.The scores of NIHSS in the four groups(12.5?4.7,3.9?4.8,3.2?4.7,2.4?4.9 respectively) had significant different(P

Objective To explore the change of serum concentrations of apolipoprotein A5(APOA5),and the relationship with levels of adiponectin and fasting insulin(FINS)in patients with coronary heart disease(CHD).Methods Blood lipids,the serum concentrations of APOA5,adiponectin and insulin were examined in 95 individuals,who were divided into two groups:51 patients with CHD and 44 healthy individuals.Results The concentrations of APOA5 and adiponectin in CHD patients were significantly lower than the healthy individuals[(230.06?115.8)?g/L and(3.03?1.85)?g/L vs(324.43?151.79)?g/L and(4.12?2.48)?g/L respectively,all P

AIM: To study the changes of plasma atrial natriuretic peptide(ANP), endothelin-1 (ET-1) and serum cardiac troponin I(cTnI) levels and the effects of ANP and ET-1 on myocardium in crush injury rats. METHODS: Crush injury was produced in SD rats,the serum levels of cardiac enzyme and cardiac troponin I,plasma levels of ANP and ET-1 were studied by automated biochemical analyzer,automated chemiluminescence assay and radioimmunoassay. RESULTS: The plasma ET-1 level was much lower ,the levels of plasma ANP and serum cardiac enzyme and cTnI were much higher after crush injury than those of the control group( P

Objective To investigate the ex pr ession of nm23-H1 protein and proliferating cell nuclear antigen (PCNA) in huma n glioma cells. Methods Expression of nm23-H1 and PCNA in 53 br ain gliomas were detected by immunohistochemistry. Results The immunohistochemistry staini ng of nm23-H1 protein in low-grade astrocytomas (grades Ⅰ and Ⅱ) was significantly higher than that in high-grade astrocytomas (grades Ⅲ and Ⅳ). The immunohistochemistry staining of PCNA in high-grade astrocytomas was s ignificantly higher than that in low-grade astrocytomas. Conclusion The lower expression of nm23-H1 protein and the higher expression of PCNA are correlated with the pathological grade of glioma cells. The expression of nm23-H1 may be used as a hopeful marker for predicting the metastastic potential of gliomas.

Objective To examine the reliability,validity,and practicability of Cognitive Emotion Regulation Questionnaire (CERQ) in hypertensive patients in China.Methods Altogether 434 hypertensive patients and 462 healthy subjects were recruited. All the subjects were assessed with the CERQ-Chinese version (CERQ-C), Dysfunctional Attitude Scale (DAS), Mood and Anxiety Symptom Questionnaire-Short Form (MASQ-SF), and Center for Epidemiologic Studies Depression Scale (CES-D). We calculated the mean inter-item correlations for the total CERQ and for each of the subscales. Cronbach's alpha coefficient was used to analyze the inter-correlation and reliability, and confirmatory factor analysis was used to examine the 9-factor model. Results 1) Hypertension group reported significantly higher score than that of healthy ones on rumination (12.19±2.51 vs. 11.51±2.60, P<0.001), catastrophizing(8.82±2.19 vs.8.11±2.70,P<0.001),and blaming others(10.76±2.11 vs. 9.88±2.48,P<0.001), and had significantly lower score than that of healthy ones on positive reappraisal(13.80±3.55 vs.14.71±4.11,P<0.001).2)Reliability:In the hypertension group the Cronbach's alpha for the total CERQ was 0.80, and that for the 9 subscales ranged from 0.71 (self-blame) to 0.90 (rumination). In the healthy group the Cronbach's alpha for the total CERQ was 0.79, and that for the 9 subscales ranged from 0.71 (positive reappraisal) to 0.90 (rumination). The mean inter-item correlation coefficient for the 9 subscales was 0.21-0.42(the hypertension group)/0.19-0.32 (the healthy group). In the hypertension group,the test-retest reliability of the total scale was 0.82, the test-retest reliability of the 9 subscales ranged from 0.73 to 0.92. The confirmatory factor analysis showed that the 9 first-order factor data fitted both 2 samples well. Conclusion CERQ meets the psychometric standard and it is reliable and valid for cognitive emotion regulation strategies, which may be regarded as an appropriate assessment tool.

Objective To study the change of postprandial triglyceride (TG) concentrations after a high-fat meal in patients with coronary heart diseases (CHD), patients with essential hypertension (EHP) and healthy controls, and to explore the optimal time point to measure postprandial TG metabolism. Methods Fifty-four CHD patients, thirty-six EHP patients and twenty-five healthy controls were recruited. The concentrations of serum TG in fasting state and at 2, 4, 5, 7 h after a single high-fat meal (800 kcal, including 50 g fat) were measured. Results The postprandial serum TG concentrations increased significantly at 2, 4, 5 h point in all subjects (all P

Objective To investigate gene variation and the relationship between gene variation and pathogenicity of transfusion transmitted virus(TTV).Methods The TTV DNA in the serum sample from a blood donor(BD) and a chronic non-A-G severe hepatitis(CSH) patient with TTV infection was amplified by using PCR.The purified PCR product was cloned and 10 clones from each case were sequenced.The sequences were compared among different clones and analyzed by Phylogentic tree.Results There were two different TTV strains in the BD and seven different TTV strains in the chronic non-A-G severe hepatitis patient.The TTV clones in the BD were of G1a subtype and those of the CSH were of G1a and G1b subtype.Conclusion Gene variant of TTV was much more complicated in the CSH patients than that in the BD ones.
