川芎嗪对离体家兔肠系膜动脉环收缩性能的影响

目的研究川芎嗪对家兔离体肠系膜动脉收缩性能的影响及其与血管内皮的关系。方法采用离体家兔肠系膜动脉环实验方法,以组胺为兔肠系膜动脉环的预收缩剂,测定血管张力变化,观察川芎嗪对血管收缩张力的影响;测定血管内皮完整组和去血管内皮组的张力变化,观察川芎嗪对血管收缩张力的影响是否为血管内皮依赖性的作用。结果川芎嗪抑制组胺引起的兔肠系膜动脉环收缩的作用与生理盐水对照组比较差异有显著（P〈0.001）;川芎嗪对于无论是内皮完整血管还是去内皮血管,都能使其由收缩状态转化为舒张状态（P〈0.001）,但是去内皮血管舒张程度显著低于内皮完整血管（P〈0.01）。结论川芎嗪对收缩着的血管诱发的舒张作用具有部分内皮依赖性。

Abstract：

Objective To study the ultrasonographic clues and methods for fetal anomalies of the aorta arch and improve prenatal detection of anomalies of the aorta arch.Methods One thousand four hundred and seventy-two cases fetus who were carried out detailed scan and whose results were confirmed were chose as study objects.Every routine fetal echocardiography included four chamber and left and right outflow tract and three-vessel trachea view(3VT).The more views which included longitudinal and coronary view of the aorta arch and coronary view of the trachea and main bronchus were obtained when the abnormality of aorta arch was suspected.Results One hundred and forty-eight cases with anomalies of aorta arch were diagnosed by ultrasonography.One case was misdiagnosed.Ninety-two fetus with anomalies of aorta arch which included 28 aortic coarctation(CoA) and 10 interrupted aortic arch (IAA) and 52 right-side aortic arch and abnormal aortic branch and 2 double aortic arch were confirmed by postmortem or postnatal echocardiography and surgery.Of the 92 confirmed cases,24 had prenatally diagnosed additional complex intracardiac anomalies.All cases with CoA and IAA presented ventricular and/or great arterial disproportion with smaller left ventricle and aorta diameter on four chamber view and 3VT.Right aortic arch (RAA) and abnormal aortic branch(AAB) displayed aortic arch located on the right side of the trachea and increased distance between the aortic arch and arterial duct and abnormal aortic arch branch-subclavian artery originating from the beginning section of the descend aorta which coursed behind the trachea with U-shaped appearance on the 3VT plane.The display rate of the transverse and longitudinal and coronary view of the aorta arch was 98.4%,90.0%,81.9%,respectively.Conclusions Disproportional ventricular and /or great arterial with smaller left ventricle and aorta diameter are the clues for CoA and IAA.Increased distance between the aortic arch and arterial duct is the clue for RSA.The transverse view of the aortic arch 3VT is the most sensitive for detecting the anomalies of the aortic arch and the most easily be obtained.The longitudinal and coronary view of the aorta arch and coronary view of the trachea and main bronchus are helpful in differentiating the anomalies of the aortic arch.

Analysis of 287 patients with aortic dissection: General characteristics,outcomes and risk factors in a single center

The general characteristics,outcomes and risk factors of the patients with aortic dissection(AD) were evaluated in a single medical center.From January 2002 to December 2008,284 patients with AD were treated and followed-up at our institution,including 105 cases of type A AD and 179 cases of type B AD.The patients in each type were divided into three groups according to management:medical treatment group(A or B),open surgery group(A or B),and stent-graft group(A or B).The characteristics and follow-up outcomes were compared between the groups or subgroups.The results showed that there was significant difference in the prognosis for type A AD between medical treatment group and open surgery group,but there was no significant difference in the prognosis for type B AD between medical treatment group and stent-graft group.Independent risk factors of follow-up mortality for patients with type A AD included a history of atherosclerosis(HR,3.807;95% confidence interval [CI],1.489 to 7.611;P=0.003),in-hospital hypotension/shock(HR,4.687;95% CI,1.846 to 11.900;P=0.001),in-hospital myocardial ischemia or infarction(HR,3.734;95% CI,1.613 to 8.643;P=0.002),pleural effusion(HR,2.210;95% CI,1.080 to 4.521;P=0.030),branch vessel involvement(HR,2.747;95% CI,1.202 to 6.278;P=0.016) and surgical treatment(HR,0.177;95% CI,0.063 to 0.502;P=0.001).And there were insignificant independent predictors for mortality of the patients with type B AD.It was concluded that there were significant differences in characteristics and one year mortality between type A AD and type B AD,but after one year,there was no significant difference in the mortality and complications of them.There were several discordant risk factors of AD,such as female gender,age,thrombus,abrupt onset of pain that were considered as the risk factors in some papers.And there was no definite risk factor of mortality in this study in the patients with type B AD.
