四种不同疾病患者血浆内皮素水平的测定

对心衰、慢性肾功能不全、脑出血、妊高征患者血浆内皮素（ＥＴ）水平测定结果表明。四种疾病患者血浆ＥＴ水平均高于正常对照组（Ｐ＜０．０１）．其中慢性肾功功不全患者较其它三组血浆ＥＴ水平有明显增高（Ｐ＜０．０１）．说明在许多情况下，内皮素可以作为一个致病因素参与疾病的发病过程，具有较普遍的病理生理意义。     

脱细胞异体真皮与自体薄皮片复合移植在老年烧伤整形患者中的应用

自体皮瓣、皮片是烧伤整形患者创面最常用的永久性覆盖物,但采用自体皮瓣、全厚或中厚皮片移植来治疗烧伤整形,常常受到供区的限制且供区愈合后亦会形成明显瘢痕。尤其对于老年烧伤整形患者,由于皮肤松弛、皮下脂肪少,烧伤后愈合慢,自愈时间长,如果采用自体皮瓣、皮片移植往往造成移植区伤口恢复不佳,且移植的皮瓣或皮片成活率较低。近年,     

健侧C7神经移位时健侧C7神经吻合口至效应器长度的测量

目的 为健侧颈7移位提供解剖学依据.方法 在30侧成人上肢标本上测量经皮下和椎前两种健侧C7移位时,正中神经返支起点至健侧C7神经吻合口之间的距离,并对两者进行比较:分别测量尺神经深支以及正中神经返支起点以上365 mm点距肱骨外上髁的长度.结果 经椎体前通路时测得效应器与健侧C7神经吻合点之间长度为(80.6±2.9)cm,经颈前皮下通路时长度为(86.5±3.1)cm.两者相比有统计学意义(t=6.32,P<0.05).测量正中神经返支和尺神经深支起点上365 mm分别位于肱骨外上髁上(4.6±0.7)cm和(6.7±0.8)cm处,两点均位于肘上部.结论 健侧C7移位修复正中神经不能恢复内在肌功能;经椎前通路优于经皮下通路;高位正中神经和尺神经损伤均位于肘上.

促甲状腺激素与心血管系统疾病的研究进展

甲状腺与心血管这两个器官系统在胚胎发育之时便有着紧密的联系,甲状腺功能障碍与心血管病发病率之间的病理生理关系一直是人们关注的焦点。甲状腺激素对整个循环系统的主要组成部分具有普遍影响。而甲状腺激素的分泌通常会受到促甲状腺激素的控制,即促甲状腺激素是直接调节甲状腺形态和功能的关键激素。血清促甲状腺激素的浓度是反映甲状腺功能最敏感的指标,它的变化往往先于甲状腺激素,从而能更早更准确地反映甲状腺功能的异常。有研究发现促甲状腺激素水平的升高与心血管疾病风险的增加有关,故现就近些年关于促甲状腺激素及心血管系统疾病的研究进展做一综述。
