血管紧张素-(1-7)对大鼠心肌缺血再灌注损伤的影响

【目的】探讨血管紧张素-(1-7)对心肌缺血再灌注损伤的影响。【方法】离体大鼠心脏采用主动脉逆灌法,灌流稳定10min后,结扎左冠状动脉前降支15min后,剪断丝线再灌流30min,造成心肌缺血再灌注损伤模型,在灌注液中加入血管紧张素-(1-7)1.0nmol/L,观察血管紧张素-(1-7)灌流对再灌注期室性心律失常、左室收缩压(LVSP)及冠脉流量的影响。【结果】血管紧张素-(1-7)组再灌注期室性心律失常程度记分为4.0±2.3,与对照组记分6.8±2.2比较明显降低(P<0.05)。血管紧张素-(1-7)组对缺血期LVSP无影响,但能预防再灌注期LVSP进一步下降,并有利于再灌注期冠脉流量的恢复。环氧化酶抑制剂吲哚美辛可阻断血管紧张素-(1-7)对再灌注期心律失常及LVSP的影响,但不能阻断其对再灌注期冠脉流量的影响。【结论】血管紧张素-(1-7)对心肌缺血再灌注损伤有一定保护作用。

目的缺血预处理和后处理能够产生一定的心肌保护效应。观察红景天苷对大鼠心肌缺血-再灌损伤的保护作用,并探讨其保护作用的机制。方法将SD大鼠按随机数字表法分为6组,每组6只:假手术组、心肌缺血-再灌注模型组、红景天苷预防组、红景天苷治疗组、红景天苷预防组+磷脂酰肌醇-3-激酶(PI3K)特异性抑制剂LY294002组(LY294002预防组)、红景天苷治疗组+PI3K特异性抑制剂LY294002组(简称LY294002治疗组)。红景天苷预防组和LY294002预防组于造模前给予红景天苷12 mg/kg腹腔注射1次/d,连续3 d;LY294002治疗组于再灌注即刻给予红景天苷12 mg/kg腹腔注射;假手术组和心肌缺血-再灌注模型组均给予等量等渗盐水腹腔注射;LY294002预防组和LY294002治疗组于冠状动脉左前降支结扎前35 min腹腔注射0.3 mg/kg体重的PI3K特异性抑制剂LY294002。采用免疫细胞化学法检测细胞内Akt、p-Akt、GSK-3β、p-GSK-3β的分布与变化,Western blot测定细胞内Akt、GSK-3β蛋白表达水平变化及磷酸化状态。结果假手术组、心肌缺血-再灌注模型组、LY294002预防组、LY294002治疗组p Akt/Akt值(0.246±0.002、0.457±0.012、0.303±0.005、0.361±0.019)较红景天苷预防组(0.857±0.014)、红景天苷治疗组(0.683±0.009)均明显降低(P<0.05)。假手术组、心肌缺血-再灌注模型组、LY294002预防组、LY294002治疗组p GSK-3β/GSK-3β值(0.137±0.004、0.380±0.026、0.148±0.013、0.267±0.050)较红景天苷预防组(0.944±0.045)、红景天苷治疗组(0.895±0.043)亦明显降低(P<0.05),而红景天苷预防组与红景天苷治疗组组间比较差异无统计学意义(P>0.05)。结论红景天苷可增加缺血-再灌注心肌中Akt/GSK-3β的蛋白表达及磷酸化,增强对缺血-再灌注损伤心肌保护作用。     

PI3K/Akt/GSK-3β/β-catenin信号通路对局灶性脑缺血再灌注大鼠神经元保护的实验研究

【目的】 探讨PI3K/Akt信号通路在大鼠脑缺血再灌注损伤中对Wnt/β-catenin信号通路的影响。 【方法】 健康雄性SD大鼠96只,采用longa法建立局灶性脑缺血再灌注模型,随机分为4组:假手术组(S组)、脑缺血再灌注组(I组)、脑缺血再灌注+bFGF后处理组(bFGF组)、脑缺血再灌注+bFGF后处理+LY294002(LY组),各组24只大鼠。各组依据缺血后再灌注时间点12、24、48、72 h再分4个亚组。应用H-E染色、TUNEL法检测皮质组织形态变化及细胞凋亡情况。采用免疫组织化学法、原位杂交法、蛋白质印迹法分别检测在各组皮质不同再灌注时间点P-Akt、GSK-3β mRNA、β-catenin的表达变化。 【结果】 免疫组织化学法检测P-Akt蛋白水平, I组和LY组每一灌注时间点都高于S组表达水平,24 h达高峰。bFGF组各亚组皮质P-Akt表达均较I组和LY组各亚组表达增多(P<0.05)。应用原位杂交和蛋白质印迹技术分别检测GSK-3β mRNA和β-catenin在缺血再灌注皮质的表达。I组和LY组各亚组缺血皮质GSK-3β mRNA和β-catenin表达高于S组,分别在48 h和72 h达高峰。与I组和LY组比较,bFGF组各亚组缺血皮质GSK-3β mRNA表达明显降低,而β-catenin蛋白表达却显著增高(P<0.05)。说明bFGF在缺血再灌注皮质通过激活Akt,抑制GSK-3β的活性,拮抗由GSK-3β、axin和结肠多发性息肉样蛋白(APC)组成的复合物,使β-catenin不能被磷酸化,游离的β-catenin在细胞浆内蓄积,继而进入胞核,促进Wnt靶基因转录,抑制细胞凋亡。从两条通路主要成员激活的时间上,Akt在皮质缺血再灌注后24 h达高峰,而β-catenin是缺血再灌注后持续增高,一直到72 h达高峰。提示β-catenin参与了脑缺血再灌注PI3K/Akt激活后的信号传导路径,Akt对β-catenin的调控作用同样在缺血性脑损伤中发挥作用,即Akt-GSK-3β-β-catenin。 【结论】 脑缺血再灌注损伤中PI3K/Akt信号通路通过GSK-3β可以调控Wnt信号通路主要成员β-catenin,这为深入研究β-catenin在缺血性脑损伤中的作用机制提供重要线索。     

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.

The comparative studies of the influences of Urapidil and Nicardipine on sino-atrial node function, atrio-ventricular node function and hemodynamics

Objective:To investigate the influences of urapidil and nicardipine on rabbit sinus function,atrio-ventricular node function and hemodynamics.Methods:Thirty-two Angora's rabbits were selected and randomly divided into four groups.U1 group:urapidil 0.25 mg/kg;U2 group:urapidil 0.5 mg/kg;N1 group:nicardipine 10 μg/kg;N2 group:nicardipine 20 μg/kg.All these medicine were administrated within 30 seconds.Measurements were taken before and after the administration of urapidil or nicardipine for the following data:mean blood pressure(MAP),heart rate(HR),sino-atrial conduction time(SACT),maximal sinoatrial recovery time(SNRTmax)corrected sinus node recovery time(CSNRT),index of sinus node recovery time(SNRTI),Wenckebach A-V conduction frequency (WB),and P-R interval.Results:Significant MAP and HR changes were identified in all of the four groups before and after administration of both urapidil and nicardipine.No significant changes could be found in the rest of the parameters.Intergroup analysis showed that SACT and CSNRT of N1 and N2 groups were shorter than those of the U2 group(P＜0.01);the MAP decreased(P＜0.01)and the HR increased drastically(P＜0.01).Conclusions:Neither urapidil(0.25 mg/kg,0.5 mg/kg)nor nicardipine(10μg/kg,20μg/kg)has any significant influence on rabbit sinus function or rabbit atrio-ventricular node function.Nicardipine could be a better choice than urapidil for parafunctional sinus node patients.

The clinicopathological and immuohistochemical analysis of solid-pseudopapillary tumor of the pancreas： report of 9 cases

Objective：To investigate the clinical features, pathological characteristics and immunophenotype of solid-pseudopapillary tumor of the pancreas（SPTP）. Methods：Nine surgically treated cases of SPTP were retrospectively reviewed. Hematoxylin and Eosin（HE） staining and immunohistochemical staining were used to analyze all cases, and the general clinical data was collected. Results：Six patients were asymptomatic except for a palpable mass. Two patients complained of vague-epigastric pain. One patient appeared jaundice. The tumor was encapsulated and solid tissues alternately with cystic tissues. Histologically, the histological structure of solid portion was pseudopapillary with a fibrovascular core. Tumor cells were uniform and medium-sized which were arranged in sheets ets or nests or pseudopapillary patterns. Immunohistochemical studies demonstrated that SPTP proved positive in vimentin（9/9 cases）, AAT（9/9 cases）, NSE（9/9 cases）, ACT（7/9 cases）, CK20（2/9 cases）, CgA（1/9 cases）, S-100（3/gcases）, PR（4/gcases）, Syn（3/9 cases） and CD56（5/9cases）, negative in CEA and ER. Conclusion：SPTP is a tumor predominantly occurring in young women frequently without special symptoms. This tumor has various characteristical histological patterns with different immunophenotype.

Investigation of Matrix Metalloproteinase -1, 2 and tissue inhibitor of matrix metalloproteinases-1 in Endometriosis

Objective： To explore the role of matrix metalloproteinase-1,2 （MMP-1, MMP-2） and tissue inhibitor of matrix metalloproteinases-1 （TIMP-1） in endometriosis. Methods： The eutopic and ectopic endometria from 40 subjects suffering from endometriosis and regular.endometria from 40 subjects （excluding endometriosis） were collected and examined by in situ hybridization technology and western blot assay. Results： Both expressions of MMP-1 and -2 were stronger in ectopic endometrium and eutopic endometrium than in normal endometrium. On the contrary, the expression of TIMP-1 in ectopic endometrium and eutopic endometrium was lower. The differences were significant （P 〈 0.01 ）. Moreover, there was no relationship among the expressions of MMP-1, 2 and TIMP-1 in ectopic endometrium. Conclusion： The expressions of MMP-1, 2 and TIMP-1 lose balance and lack of periodic changes in ectopic endometrium , which explains the biological invasive behavior of endometriosis. It was suggested-that regulating the balance between the MMPs and TIMP-1 should be an ideal therapeutic target to endometriosis.
