Tei指数在监测妊娠合并心脏病伴肺动脉高压患者右心室功能中的作用

Objective To investigate clinical value of Tei index used for monitoring right ventricular (RV) function in pregnant women complicating cardiac disease accompanying pulmonary hypertension(PH) and the influence on left ventricular(LV) function due to overload pressure of RV. Methods Fifty-eight pregnant women complicating cardiac disease (including 32 cases with congenital heart disease,14 cases with rheumatic heart disease and 8 cases with arrhythmia)were enrolled in this study, among 26 cases coexisted with pulmonary hypertension. According to the pressure of PH, those patients were divided into three groups:11 cases in mild group[30-49 mm Hg (1 mm Hg=0.133 kPa)],9 cases in moderate group (50-79 mm Hg)and 6 cases in severe group (≥80 mm Hg). In the mean time, 15 healthy pregnant women were matched as control. Tei index were measured for LV and RV respectively. Results (1) The isovolumetric relaxation time [IRT,(93±52) ms] and isovolumetric contraction time [ICT,(66±41) ms] of RV in PH group were significantly higher than normal controls [(39±19) ms in IRT and (38±20) ms in ICT] and the other patients without PH group[(59±12) ms in IRT and (43±19)ms in ICT, P<0.01, P<0.05;P<0.05,P<0.05]; however, ejection time (ET) was(239±46) ms significantly shortened in PH group (P<0.05,P<0.01) when compared with (250±41) ms in patients without PH and (299±38) ms in normal controls. Tei index in PH group were 0.72±0.49, which were significantly higher than 0.38±0.12 in normal controls and 0.43±0.16 in patients without PH (P<0.01,P<0.05). (2) The IRT[(99±27)ms] and ICT[(71±40) ms] of LV in PH group were significantly higher than in normal controls [(88±20) ms,(50±24)ms] (P<0.01,P<0.01). ET of LV in PH group [(202±26)ms] were significantly shortened that (290±21)ms in normal controls and (220±36)ms in patients without PH (P<0.01,P<0.05). Tei index of LV in PH group were significantly higher than 0.43±0.15 in normal controls and 0.58±0.21 in patients without PH (P<0.01,P<0.05). (3) Positive correlation between Tei index of RV and pressure of pumonaroy artery were observed (r=0.84, P<0.01). (4) Tei index of RV in severe PH were significantly higher than mild PH (0.75±0.43 vs. 0.68±0.35, P<0.01) and moderate PH (0.75±0.43 vs. 0.71±0.14, P<0.05). Conclusions (1)The Tei index is a novel efficient Doppler index in assessing RV function of pregnant women complicating cardiac disease accompanying PH. And the fluctuation of Tei index might reflect seriousness of the disease. (2) The overload pressure of RV pressure due to PH has significant influence on LV function.

c-fos基因的表达与软骨的增殖及分化

目的:转录因子激活蛋白1中的重要亚单位c-fos与软骨细胞增殖、分化以及细胞的生理进程和炎症等疾病密切相关。资料来源:应用计算机检索PUBMED2000-01/2005-01和EBSCO2000-01/2005-01期间的相关文章,检索词为“c-fos”,并限定文章语言种类为英文。同时计算机检索万方数据库2000-01/2005-01期间的相关文章,检索词为“原癌基因,立早基因”,并限定文章语言种类为中文。资料选择:对资料进行初审,以关键词“软骨,增殖,分化,炎症”为条件对所获文献进行二次检索。纳入标准:文章应涉及c-fos基因与软骨细胞增殖、分化及炎症的内容。排除标准:重复研究或Meta分析类文章。资料提炼:共收集到24篇相关文献,17篇文献符合纳入标准,排除的7篇文献是由于内容陈旧或重复。资料综合:对剩余的17篇文献全文中的相关信息进行分类综合研究。软骨细胞发育成熟过程中,在各种生长因子和外界环境变化作用下,会发生明显形态和生化成分的改变。在这一过程中,作为细胞信号通路上的信使之一的c-fos起到了重要的作用。过度的表达c-fos会诱发软骨肉瘤,软骨细胞不能正常成熟,而去除c-fos则肢体发育短小,生长板断裂,生长期细胞减少,肥大带扩大。软骨关节炎早期,软骨表现出一种自我修复的能力,细胞体积变肥大,蛋白聚糖增加。当后期平衡被打破,炎症所致破坏效应则显现出来,其中c-fos基因充当了重要信使。结论:c-fos基因可以结合在许多基因的启动子上参与转录调控,并在转录前后对蛋白结合DNA等多个水平的表达进行调节,与软骨的分化和炎症密切相关,提示可以针对软骨疾病患者开展以c-fos为靶点的药物及基因治疗。
