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 compare the lipid lowing effect and the clinical safety between intensive therapy with Chinese medicine Zhihitai and atorvastntin in patients with moderate and high risk of atherosclerosis. Methods All the patients were randomly divided in to a Zhibitai group (n = 85) receiving 480 mg of Zhibitai orally twice a day or an atorvastatin group (n = 84) receiving 10 mg atorvastatin orally once daily. Blood lipoproteins, myocardial enzymes, fiver and renal function were measured before treatment and at the fourth and eighth week after therapy , while high sensitive creactive protein (hs-CRP), P-selectin, matrix-metall proteinase-9 (MMP-9) and soluble intercellular adhering molecule-1 (SICAM-1) were detected before treatment and eighth week after therapy in all patients. Results TC and LDL-C were significantly decreased while HDL-C was increased in both groups after 4 and 8 weeks treatment (P < 0. 05). TG was decreased in Zhibitai group after 4 and 8 weeks of treatment, but it was decreased in atorvastatin group only after 8 weeks of treatment. Inflammatory factors such as hs-CRP, P-selectin, MMP-9, SICAM-1 were decreased significantly (all P < 0. 01), but there was no significant difference between the two groups. There were no difference in liver and kidney function, myocardial enzymes and incidence of muscle-ache and digestive system side reaction. ConclusionsBesides the lipoprotein disorder, inflammatory factors in patients with moderate and high risk of atherosclerosis could be regulated with intensive therapy of Zhibitai. Most importantly, it is safe to use Zhibitai clinically.

Objective To examine the effects and mechanisms of simvastatin and fenofibrate, and combination of the two drugs on the expression of apolipoprotein M (apoM). Methods The male C57BL/6N mice ( n =32) were random divided into four groups, including control group (with no special treatment), statin group (with simvastatin [10mg/( kg · d) for 4 weeks], fibrate group (with fenofibrate [100mg/( kg · d) for 4 weeks] and combination group ( with simvastatin [10mg/( kg· d)] and fenofibrate [100mg/( kg · d) for 4 weeks]. The levels of apoMmRNA and protein, hepatic nuclear factor (HNF-1α)mRNA, liver X receptor-α (LXRα) mRNA in mouse liver were measured. Results Both of simvastatin and fenofibrate can increase the expression of apolipoprotein M ( 1.97 ± 0. 04,2. 02 ± 0. 02 ) and HNF-1αmRNA ( 1.74 ± 0. 05,1.71 ± 0. 04). Combination group obtained more effects than either single agent ( P ＜ 0. 05 ). Simvastatin could decrease the expression of LXRα mRNA ( 1.00 ± 0. 02 ) ( P ＜ 0. 05 ). Fenofibrate could increase the expression of LXRα mRNA(2. 80 ±0. 04) ( P ＜0. 05). No significant difference in LXRα expression was seen between combination( 1.56 ±0. 03 ) and control group( 1.53 ±0. 03 )( P ＞0. 05). Conclusions Simvastatin and fenofibrate can increase apoM expression. Treatment with combination of the two drugs is more effective, and the mechanism might be related to the regulation of HNF-1α and LXRα.

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.
