Between 6th and 14th weeks afteconstricted bilateral renal arteries, the blood pressure in the majority of RHRSP with cerebral infarction was obviously higher than in RHRSP without cerebral infarction (28. 8±2. 24kPa～32. 3 ±2. 88kPa, 26. 2±2. 01～28. 3±2. 33kPa respectively). Severe hyalinosis, fibrosis, wall hypertrophy, lumen stenosis, and even microaneurysm formation in cerebral small arteries in RHRSP with cerebral infarction were found, while slight to mild arteriolosclerosis in RHRSP was found without cerebral infarction.

本实验发现，RHRSP在经受不同水平的低血压后，产生脑梗塞的大多数（32/38只）在肾动脉狭窄术后第六周至第十四周，血压为28.8±2.24 kPa～32.3±2.88 kPa（216±17mmHg～242±22mmHg），显著高于无脑梗塞的RHRSP，并且发现这些RHRSP的脑内小血管呈严重的透明样变、纤维素样变性，管壁增厚，管腔狭窄，部分有微动脉瘤形成；而无脑梗塞的RHRSP的血压为26.2±2.01kPa～28.3±2.33 kPa（200±15mmHg～212±17.5mmHg），其脑内小血管呈轻至中度的动脉硬化改变。

The patient was a 66-year-old male who presented with paraparesis. On examination, strength was 5/5 in both upper extremities and 3-4/5 in both lower extremities. Pricking sensation was relatively retarded below the sixth thoracic vertebra on both sides. Fine-touch sensation was limited below the ninth thoracic vertebra on the right side and below the eleventh thoracic vertebra on the left side. Responses to vibration and joint position sense were well preserved. Deep tendon reflexes were increased in his legs. He had voluntary anal contraction and preserved anal and bulbocavernous reflexes. MRI revealed dissection of the descending aorta from T4 to T10 levels with thrombus present in the false lumen, and the thoracic cord was marked atrophy, especially from T6 to T8 levels. To the best of our knowledge, no such case had been reported so far.

这是一位66岁的男性病患，到院时以下半身轻截瘫来表现，检查后发现其双上肢肌力为5/5而双下肢肌力则为3-4/5，刺痛觉在两侧第六胸椎以下异常，轻触觉在右侧第九胸椎与左侧第十一胸椎以下异常，震动觉与本体感觉则皆属正常，深肌腱反射在两下肢均有异常增强的情形，肛门的主动收缩正常且肛门反射与球体海绵体肌反射均正常，核磁共振影像显示降主动脉在T4到T10处有剥离的情形并於伪腔内发现血栓，此外，病患之胸部脊髓则有明显萎缩的现象，以T6到T8处最为明显，就目前可见的文献资料，并无类似的报告被提出。

The staining of F-actin in the ischemia reperfusion group was decreased significantly （P.05） compared with the normal control group. There was a marked loss of canalicular microvilli and distension of canalicular lumen in the ischemia reperfusion group. The staining of F-actin in the LA group was significantly increased than those in the I/R group （P.05）. Conclusions: Ischemia reperfusion induces an disruption of bile canalicular F-actin microfilaments and a loss of microvilli. Alpha-lipoic acid can protect bile canalicular F-actin microfilaments against IRI.

肝脏I/R可造成胆小管F-actin微丝破坏、微绒毛丧失，导致胆小管收缩减弱，胆汁排泄功能受损，这可能是大鼠肝脏I/ R后缺血型胆道病变发生的主要机制；α-硫辛酸通过清除氧自由基，降低脂质过氧化反应，调节细胞内氧化剂-抗氧化剂的含量，保护胆小管F-actin微丝结构免遭缺血再灌注损伤破坏，进而预防和治疗缺血型胆道病变。

Those who have lived and followed the course of events in an intelligent manner during the pontificates of Pius IX, Leo XIII, and Pius X cannot fail to be impressed with the titles given to each by the prophecies of St. Malachy and their wonderful appropriateness: Crux de Cruce Pius IX; Lumen in caelo Leo XIII; Ignis ardens Pius X. There is something more than coincidence in the designations given to these three popes so many hundred years before their time.

那些居住和遵循了事态的发展过程中一种智能的方式在pontificates的比约九，利奥十三世，和比约X可以不能不留下深刻的印象，与职称给每所预言的圣malachy和他们精彩的适宜性：症结德cruce比约九；腔caelo利奥十三世； ignis ardens比约十，有一些东西多的巧合，部队番号给这三个教皇这么多百年几年前，自己的时间。
