127例健康儿童左室收缩时间间期的研究

应用CTH—Ⅱ型心功能检测仪和STI软件,通过心电机械图研究了127例健康学龄前和学龄期儿童的STI。结果显示,学龄前儿童STI无性别差异,学龄期儿童男、女之间主要是HR、R—R不同。男、女学龄期儿童均较学龄前儿童的PEP、ICT、Q—U、及PEP/LVET、ICT/LVET、Q—U/LVET值大,有统计学意义。学龄前儿童较学龄期儿童EF显著为高。这些差异与儿童期的生理特点是吻合的。作者认为,儿童期的STI标准应区别年龄段制订;学龄期儿童在分析HR、R—R等时应考虑性别差异。     

盐酸青藤碱对心脏收缩间期的影响与其血药浓度的关系

给家兔静注盐酸青藤碱（SIN）20mg／kg，于给药后6h内不同时间测定心脏收缩间期（STI）并用薄层扫描法测定血药浓度。根据Hill作图法求出药物对STI的延长效应E与血药浓度C的数学关系式为：ELVET＝28·C2.038／（C2.038＋1．52.038）；EQS2＝27·C1.712／（C2.712＋2．41.712）；而EPEP与血药浓度有一定的量效关系但用Hill方程时直线相关不显著。提示SIN对STI中LVET和QS2的延长效应与其血药浓度呈显著的效应-浓度依赖关系。     

克山病区低硒粮饲养大鼠心脏收缩功能与舒张功能的变化

将Sprague-Dawley大鼠随机分为3组,分别用克山病区低硒粮饲料、病区粮加亚硒酸钠(Na_2SeO_3)饲料和本校常规饲料喂养,用以研究克山病区低硒粮对心脏收缩功能与舒张功能的影响。实验结果发现,动物饲养两个月时,与补硒组和常规饲料组相比,低硒组大鼠的T值显著延长(P<0.05);动物饲养3个月时,低硒组大鼠的dp/dtmax、-dp/dtmax显著减小(P<0.05),T值继续延长(P<0.05)。实行冠状动脉结扎术后,3组动物的各项心功能指标均发生严重损害,但常规饲料组的损害较轻,与低硒组相比,dp/dtmax和T值有显著性差别(P<0.05)。实验结果说明,克山病区低硒粮能造成心脏收缩与舒张功能损害,补硒则有保护作用。     

多发性骨髓瘤患者氧自由基代谢状态的研究

测定了不同病期多发性骨髓瘤（MM）患者内源性抗氧化酶—红细胞超氧化物岐化酶（SOD）、谷胱甘肽过氧化物酶（GSH－Px）、过氧化氢酶（CAT）活性，血浆铜锌SOD（CuZn－SOD）、锰SOD（Mn－SOD）及总SOD（T-SOD）活性，血清铜、锌、锰、硒含量及血浆脂质过氧化物（LPO）含量。结果表明非缓解期MM患者红细胞3种抗氧化酶活性明显降低，血浆T－SOD、CuZn－SOD及Mn-SOD活性显著升高，血清锌、锰、硒含量降低，铜含量增高，血浆LPO含量明显增高。提示患者体内氧自由基含量增多，代谢增强，抗氧化能力明显减弱，且与疾病的发展及严重程度有关。     

多发性骨髓瘤患者超氧化物歧化酶和脂质过氧化物的改变及其意义

用邻苯三酚自氧化法和改良硫代巴比妥酸（ＴＢＡ）荧光微量法测定了多发性骨髓瘤（ＭＭ）患者初发期、缓解期和复发期红细胞超氧化物歧化酶（ＳＯＤ）活性和血浆脂质过氧化物（ＬＰＯ）含量。结果表明：ＭＭ初发和复发病例红细胞ＳＯＤ活性明显降低，血浆中ＬＰＯ含量明显增高，较正常对照均有明显差异。缓解期患者的ＳＯＤ活性和ＬＰＯ含量大致恢复正常水平。ＭＭ红细胞ＳＯＤ活力与血浆ＬＰＯ含量呈负相关（ｒ＝－０．４２５，Ｐ＜０．０５）），与血红蛋白浓度呈正相关（ｒ＝０．７２２，Ｐ＜０．００１），与骨髓中浆细胞百分数呈负相关（ｒ＝－０．５２６，Ｐ＜０．０５）。以上结果提示自由基损伤作用参与了ＭＭ的发生、发展和转归过程，且与病情的严重程度有关。     

神经内分泌分化与前列腺癌进展及预后的关系

目的研究神经内分泌分化(neuroendocrine differentiation,NED)与前列腺癌(prostate cancer,PCa)发展及预后的关系。方法收集有随访资料的61例PCa穿刺活检标本,采用免疫组化法检测嗜铬素A(chromogranin,CgA)、神经特异性烯醇化酶(neuron-specific enolase,NSE)、突触素(synaptophysin,Syn)在选定标本中的表达,分析NED与PCa各临床病理参数及患者生存时间的关系,多因素Cox风险模型分析影响PCa患者预后的危险因素。结果 61例PCa患者中有24例伴NED(39.3%),NED表达水平随着Gleason评分增加及穿刺前前列腺特异性抗原(prostatespecific antigen,PSA)水平升高而逐渐升高(P<0.01),Syn分别与NSE及CgA表达水平呈正相关性(P<0.01)。伴NED组PCa患者累积生存率明显低于不伴NED组(P<0.01),多因素Cox回归分析显示Gleason评分、NED是PCa患者生存的独立危险因素(P<0.01)。结论 NED与PCa发展及患者不良预后密切相关,是判断PCa患者预后的独立因素。

醛固酮及螺内酯对肝星状细胞中TIMP-1和MMP-2mRNA表达的影响

目的观察醛固酮及螺内酯对活化的肝星状细胞(HSC-T6)作用后不同时间段MMP-2和TI MP-1 mRNA的表达情况。方法采用RT-PCR的方法测定HSC-T6中MMP-2、TI MP-1 mRNA的表达。结果活化的HSC可表达MMP-2及TI MP-1的mRNA。醛固酮组MMP-2、TI MP-1的mRNA在48、72 h表达均高于对照组,在作用24、48、72 h时MMP-2、TI MP-1的mRNA的表达随时间递增。而螺内酯组则相反。醛固酮加螺内酯组与单加醛固酮组相比MMP-2、TI MP-1的mRNA表达下降。结论醛固酮可能通过促使MMP-2及TI MP-1 mRNA的表达促纤维化,螺内酯可抑制这一作用。

EXPRESSION OF MATRIX METALLOPROTEINASE-9 IN HUMAN ABDOMINAL AORTIC ANEURYSMAL TISSUES

Objective To study the effects of MMP-9 （Matrix Metalloproteinase-9, MMP-9） in the pathogenesis of abdominal aortic aneurysms （AAAs） by localizing the expression of MMP-9 in the aneurysmal tissues. Methods By , the frozen sections （5μm） with aneurysmal tissues （n = 10） were incubated with MMP-9 antibody-added agents, then the sections were stained and observed under the microscope to localize the expression of MMP-9, which displayed a brown precipitate within the arterial walls. The normal arterial wall tissues（n= 10） and the diseased arterial wall tissues from the arterial occlusive diseases （AODs） （n= 15） were also immunized exactly the same way as control. Results A quantity of positive granules which appeared within the aortic media showed the strong expression of MMP-9 in the AAAs, with the positive rate reaching 95 % （19/20）, while no expression of MMP- 9 was observed in the normal artery. However, the scattered distributed positive granules were seen within the arterial wall of some cases of the AOI）s, implying the weak positive expression of MMP-9 in this disease with the positive rate of 26.7% （4/15）. There was a significant difference of the expression of MMP-9 within the arterial wall between the AAAs and AODs（P〈0.01 ）. Conclusion High expression of MMP-9 within the aortic media faciliatates the degradation of collagen and elustin fibres and subsequent dilation of the aortic artery , thus playing an important role in the pathogenesis of AAAs. To refrain MMP-9 from enhanced expressing within the aortic wall is of clinical significance in the prevention and treatment of AAAs.
