ABSTRACT
Objective To investigate the influence of hydroxyethyl starch combined with strengthening anti -platelet therapy on the short-term clinical efficacy,TCD index and recurrence rate of patients with TIA secondary to cerebral artery stenosis.Methods 80 patients with TIA secondary to cerebral artery stenosis were chosen,and they were randomly divided into two groups according to the digital table,each group in 40 cases.The control group received strengthening anti-platelet therapy alone,and the observation grouP received hydroxyethyl starch on the basis of control group.The short-term clinical efficacy,the blood flowvelocity of ACA and MCA before and after treatment,the TIA recurrence rate,the incidence of cerebral infarction and adverse reactions of both two groups were compared.Results The short-term effective rates of the control group and observation group were 77.50％,97.50％,respectively.The short-term effective rate of the observation group was significantly higher than that of the control group(x2 =12.33,P ＜ 0.05).The blood flow velocity of ACA and MCA of the control group after treatment were (51.05 ± 9.83) cm/s,(54.88 ± 6.62) cm/s,respectively,which were significantly lower than those of the observation group [(59.12 ± 12.07) cm/s,(62.65 ± 8.09) cm/s,t =3.17,2.96,4.03,4.74,3.67,4.05,all P ＜ 0.05].The TIA recurrence rate and the incidence rate of cerebral infarction of the control group were 22.50％,12.50％,respectively,which were significantly higher than those of the observation group(5.00％,0.00％,x2 =11.75,14.06,all P ＜ 0.05).The incidence rates of adverse reactions of the control group and observation group were 12.50％,10.00％,respectively.There was no significant difference in the incidence rate of adverse reactions between the two groups (x2 =1.75,P ＜ 0.05).Conclusion Hydroxyethyl starch combined with strengthening anti-platelet therapy in the treatment of patients with TIA secondary to cerebral artery stenosis can efficiently relieve the symptoms of neurological function,higher the level of cerebral blood perfusion,reduce the risk of TIA recurrence and cerebral infarction,and not increase the incidence of adverse reactions.
ABSTRACT
A Review The elastin has been investigated since the 1950 s, and it has been found that elastin relates to the vascular diseases in recent years. In this review, the elastin gene structure, distribution and its role in the pathogenesis of vascular diseases and aging are summarized.
ABSTRACT
Objective To investipate the cerebral autosomal dominat arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) through the clinical features , pathology, neuroimage, and molecular genetics as well as the family tree of a case as to exploring the diagnostic method of the disease .Methods Systematic study on the clinical manifestations, genetic site, neurologic and muscular biopsy was performed. Results The main clinical features including poor memory and history of stroke were found. Neuroimaging examination showed multiinfarct lesions and leukoencephalopathy. Biopsy indicated the arteriolar hyalinosis,GOM and osmiophilic granule. A family history was confirmed. A mutation on the fourth exon of notch 3 gene was revealed. And no risk factors of hypertension and arteriosclerosis were found. All these features are in conformity with those of CADASIL.Conclusion CADAIL is not rare and is possible to be defined in vivo by way of dermal biopsy,examination of gene and neuroimage characteristics.
