Objective To explore the relationship between epilepsy and stroke,the features of secondary epilepsy and its treatment. Methods 233 stroke patients were observed and the clinical data of 21 patients who had secondary epilepsy were analyzed. Results Secondary epilepsy after stroke was mainly seen in the cortical stoke patients, the incidence of epilepsy of the cortical stroke group was 16.7% , which was significantly higher than that of the gubcortical stroke patients(5.7% ) ,and there was significant difference between the two groups. The incidence of epilepsy of stroke with a lesion >4cm group was 17. 3% .which was significantly higher than that of stroke with a lesion <4cm group(5.4% ), there was also significant difference between the two groups. There was no significant difference between ischeraic stroke and hemorrhagic stroke(P>0.05). Conclusion The incidence of secondary epilepsy after stroke had no correlations with the stroke types,but was related to the area and the location of the stroke.

OBJECTIVE To investigate and analyze the cause of the cross infection of Methicillin-resistant Staphylococcus aureus(MRSA) in ICU patients,and to apporach its preventive and control measures.METHODS Eiological inspection and sanitary monitoring have been done in ICU where there were two MRSA patients from June 6th,2008 to August 1st,2008.RESULTS MRSA has been detected on the hands of the ICU medical staff,on the bed-desks,on the switches of the vacuum extractor and gas supply unit on the wall,and in the NS for inhaling sputum.The separation rate were 37.5%,20.0%,54.5%,37.5%,87.5%.CONCLUSIONS ICU patients are prone to be infected with MRSA,which has a strong drug resistance and the infection is difficult to be treated.The cross infection can be prevented and controlled by rational administration,sterile operation and insulation.

In this paper,a time-frequency approach is used for the recognition and analysis of ECG signals for a normal or an abnormal patient.An iterative deconvolution procedure is applied to calculate the time-frequency representations.This method can enhance the resolutions of the signals.

OBJECTIVE:To systematically evaluate the efficacy and safety of sodium valproate versus diazepam in the treat-ment of status epilepticus in adults,and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from Med-line,EMBase,PubMed,Cochrane Library,CJFD,VIP datebase,CBM and Wanfang database,the randomized controlled trials (RCT) about sodium valproate (test group) versus diazepam (control group) in the treatment of status epilepticus in adults were collected. Meta-analysis was performed by using Rev Man 5.0 statistical software after extracting data and evaluating quality. RE-SULTS:A total of 5 RCTs were included,involving 276 patients. Results of Meta-analysis showed that recurrence rate of epilepsy in 48 h in test group was significantly lower than that of control group [OR=0.39,95%CI(0.16,0.96),P=0.04]. Compared with the control group,the effective rate controlling epilepsy within 2 h[OR=1.76,95%CI(0.88,3.52),P=0.11] and incidence of liver injury[RR=1.19,95%CI(0.38,3.70),P=0.77] were no significant differences. CONCLUSIONS:The efficacy and safety of sodi-um valproate was equivalent to diazepam in the treatment of status epilepticus in adults,however,sodium valproate was superior to diazepam in terms of controlling recurrent effect. Due to methodology limit of included studies,large-scale and high quality RCT are required for further validation of the conclusions.

ObjectiveThe present study aimed to determine whether or not dual paroxysm proliferator-activated receptor (PPAR) agonist,WY14643,improved the dysfunctioned vascular endothelium in hypertension by reducing endothelium-derived contracting factors ( EDCFs ),and to explore the molecular mechanism it was involved in.MethodsIsometric tension in isolated thoracic aortic rings of spontaneously hypertensive rats was recorded.Endothelium-dependent contractions evoked by acetylcholine in the presence of L NAME were reduced by fenofibrate.Cyclooxygenase 1 ( COX1 ) activities were determined by analyzing the peroxidase activity of cyclooxygenase colorimetrically by using ELISA kit.ResultsCompared to the control group,WY14643 significantly decreased the vasoconstriction in aorta of the SHR rats(P=0.014).PPARα antagonist MK866 enhanced the vascular contractility of SHR rats that were incubated with 10.0μmol/L WY14643( P=0.021 ).PPARΥ antagonist GW9662 did not significantly affect the vascular contractility of SHR rats that were incubated with 10.0 μmol/L WY14643( P=0.061 ).The levels of serum PGFlα(P=0.012),2α( P =0.019) and TXB2(P=0.023) in SHR rats incubated with 10.0 μmol/L WY14643 were significantly lower than the control group,respectively.Under the condition of the existence of vascular endothelium,the expression of COX-1 in SHR rats incubated with WY14643 was significantly lower than that in SHR rats incubated without WY14643 (P=0.017).ConclusionsThose data showed that WY14643 reduced the release of EDCFs,it suggests that WY14643 protects against vascular diseases through the PPAR activators in spontaneous hypertension.

Background Exfoliation syndrome is a systemic disease with abnormal accumulation of extracellular matrix.Oxidative stress and imbalance between matrix metalloproteinases(MMPs) and tissue inhibitor of matrix metalloproteinases(TIMPs)may play an important role in the pathogenesis of exfoliation syndrome.Researches showed that the incidence of exfoliation syndrome is higher in Uyghur nationality than that in Han nationality.However,whether the imbalance of serum MMPs and TIMPs is associated with pathogenesis of different ethnic groups is unclear.Objective The aim of the study was to discuss the change of serum MMP-9 and TIMP-2 in Uyghur patients.Methods This study protocol was approved by Ethic Committee of Xinjiang Medical University and followed Declaration of Helsinki.A prospective cohort study was performed.Forty Uyghur nationality (46 eyes) with exfoliation syndrome were collected from March 2012 to May 2013 in Affiliated First Hospital of Xinjiang Medical University and First People Hospital of Kashi.Forty cases(40 eyes)age-and gender-matched normal volunteers were included in the same duration.The peripheral blood was collected under the informed consent.Serum MMP-9 and TIMP-2 levels were detected by ELISA,and the results between the two groups were compared using independent samples t test.Results Slit-lamp examination found that part of pigmentation was depigmented and white dandrufflike substance attached in the pupil margin in all the patients,and stripping white dandruff-like substance was deposited in the front surface of the lens capsule which distributed in 3 zones.The pupils were disk-shaped pupil,and the surrounding area was the ring granular and the middle was transparent area without ablative material after dilation.Serum MMP-9 levels were (57.88±18.63)μg/L in the exfoliation syndrome group and (9.35±2.78)μg/L in the normal control group;serum TIMP-2 levels were (17.36±4.66) μg/L in the exfoliation syndrome group and (25.73±3.59) μg/L in the control group.The ratios of MMP-9/TIMP-2 were 3.57± 1.45 in the exfoliation syndrome group and 0.37±0.11 in the control group,with statistically significant differences in serum MMP-9 and TIMP-2 levels as well as ratio of MMP-9/TIMP-2 between the two groups(t=11.52,-6.36,9.87,all at P=0.00).Conclusions The upregulation of serum MMP-9 and downregulation of serum TIMP-2 are found in Uyghur patients with exfoliation syndrome.It is verified that the imbalance of serum MMP-9 and TIMP-2 contributes to the pathogenesis of exfoliation syndrome in Uyghur patients.
