余尚贞以六戊年麦门冬汤治疗高血压经验浅析

高血压病为临床最常见的慢性病,余尚贞根据多年临床经验辨证,结合开、阖、枢理论,以太阴阳明升降不和为病机,从太阴阳明入手论治高血压病,结合五运六气选方六戊年麦门冬汤,临床治疗多例,疗效甚佳。开、阖、枢理论源于内经,是对人体三阴三阳经生理功能、病理特点及其相互关系的概括,我们可从中窥得开、阖、枢理论之部分面貌,比如对太阴、阳明经的了解,并拓展中医在治疗高血压病方面的治疗思路。     

血管生长因子在冠心病治疗性血管新生中的应用

血管生长因子在血管新生过程中起着重要作用.大量的动物研究显示在给予血管生长因子后能够有效地促进缺血心肌的血管新生,改善局部血流灌注,提高心功能.但由于临床Ⅱ期试验未取得预期的阳性结果,给治疗性血管新生的应用带来了新的挑战,众多问题有待进一步优化和解决.     

一种防脱出易制作义眼台的研制

目的探讨一种新型简易防脱出的义眼台的制作方法与效果。方法根据眼球摘除后的解剖特点设计义眼台大小,选择聚甲基丙烯酸甲酯和涤纶布为材料制作复合材料义眼台,并对6只家兔行眼球摘除后置入义眼台,经HE染色观察及肉眼观察术后不同时间置入物与眼周围组织的解剖关系。结果聚甲基丙烯酸甲酯部分与组织无黏连,涤纶布形成牢固黏连,周围有纤维组织长入并包绕,义眼台无脱出、移位。结论以聚甲基丙烯酸甲酯和涤纶布为材料制作复合义眼台,方法简易,效果可靠,组织相容性好,术后反应轻,值得在临床上推广使用。

三维立体培养法诱导去分化软骨细胞Ⅱ型胶原的重新表达

目的用藻酸盐三维立体培养法及离心管聚集体诱导培养法促进去分化的永生化软骨细胞第50代(IHACs50)重新表达软骨细胞的Ⅱ型胶原标志性表型。方法利用藻酸盐三维立体培养法以及离心管聚集体诱导培养法分别诱导培养去分化的永生化人关节软骨细胞第50代,然后用Ⅰ、Ⅱ、Ⅲ型胶原的免疫组织化学染色、Ⅱ型胶原的逆转录-聚合酶链反应(RT-PCR)检测、激光共聚焦显微镜检测、胶原定量检测该永生化软骨细胞的Ⅱ型胶原表型表达情况。结果免疫组织化学染色、激光共聚焦显微镜检测、RT-PCR检测分别提示藻酸盐三维立体培养法和离心管聚集体诱导培养法使去分化永生化人关节软骨细胞的Ⅱ型胶原染色阳性以及621 bp的Ⅱ型胶原mR- NA表达,Western blot和3H-脯氨酸标记SDS-PAGEⅡ型胶原定量检测发现前者促进Ⅱ型胶原分泌较后者多。结论去分化永生化人关节软骨细胞可以经不同的诱导方法而重新表达Ⅱ型胶原表型,藻酸盐三维立体培养法因与软骨细胞的生理环境相似,故促进Ⅱ型胶原重新表达较多。     

下肢严重开放性损伤的保肢治疗

高能量损伤导致的下肢严重开放性损伤的保肢治疗，对骨科医生来说是一个挑战。随着修复重建技术的提高和术后辅助治疗的完善，给保肢治疗带来了希望，但总体疗效仍不理想。我院自2003年1月～2004年12月共对32例下肢严重损伤患者行保肢治疗，现结合相关文献进行回顾性分析，旨在探讨保肢的指征、肢体重建的方法与时机及保肢失败的原因。     

FasL基因表达对缺氧状态下直肠癌细胞增殖凋亡的影响

Objective To elucidate the effect of FasL gene expression on the proliferation and apoptosis of hypoxic rectal carcinoma cells. Methods The normoxic expression level of FasL in HR-8348 subtype cells (HR-8348B, HR-8348L, HR-8348F and HR-8348As) with different invasive power were verified by Western blot. Hypoxia models for HR-8348B, HR-8348L, HR-8348F and HR-8348As were constructed with chemical modeling, then the FasL levels in all groups at 12 h after hypoxia were quantitated by Western blot. Distribution of different cell life cycles was determined with flow cytometry. Cell reproductive activities were detected with MTT method, and cell apoptesis was assessed with TUNEL. Results FasL protein was pigmentized at the position of 40 000 by Western blot, and the expression level of FasL was significantly higher in HR-8348F cells than those in HR-8348B, HR-8348L and HR-8348As cells(F=361.149, P<0.01) in normoxia. At 12 h after hypoxia, the FasL level was also significantly higher in HR-8348F cells than those in other groups (F=278.766, P<0.01), but was not markedly different as compared to themselves in normoxia (t=1.762, P>0.05). The proliferation index was significantly higher in HR-8348F (60.43±3.72) than those in HR-8348B (40.01±3.30), HR-8348L (41.30±4.06) and HR-8348As cells (35.87±4.39), respectively (F=39.477, P<0.01). However, both inhibition rate of proliferation and apoptotic index were remarkably lower in HR-8348F (17.30±1.98 and 13.10±1.04) than those in HR-834B (33.70±4.33 and 21.60±1.31), HR-8348L (34.20±3.92 and 20.10±1.15), and HR-8348As (38.00±4.55 and 23.90±1.23), respectively (F=28.811 and 76.462, respectively, P<0.01). Conclusion The expression enhancement of intracellular FasL in rectal carcinoma in hypoxia can lead to accelerated proliferation and reduced apeptosis of cells, which will promote tumor cells to adapt microenvironmental hypoxia.     

松龄血脉康抑制肺动脉高压的实验研究

为观察松龄血脉康胶囊对肺动脉高压大鼠肺动脉压的影响，取１００只健康Ｗｉｓｔａｒ大鼠，其中６０只背部注射野百合碱ｍｏｎｏｃｒｏｔａｌｉｎｅ，ＭＣＴ８０ｍｇ／ｋｇ复制出肺动脉高压模型。再将其分为两组，各３０只，其中一组以标准饲料喂养，另一组加用松龄血脉康胶囊１．５ｇ·ｋｇ－１·ｄ－１。其余４０只健康大鼠做为正常对照组，在实验当天、７天、１４天、２１天、２８天、３５天从各组中随机抽取５只行右心导管测肺动脉压。结果：注射ＭＣＴ后肺高压组２８天时达高峰，但加用松龄血脉康组上升幅度明显小于未用药组。结论：松龄血脉康有显著抑制大鼠肺动脉高压发展的作用
