Case ReportsSurgical treatment of DeBakey type I aortic dissection using the "elephant trunk technique".
To review the indications, operative methods and postoperative management of the "elephant trunk technique", and to report two cases of DeBakey type I aortic dissection treated with the "elephant trunk technique". ⋯ The "elephant trunk technique" is a multiple stage approach in the treatment of extensive aneurysmal diseases of the aorta. The procedure is indicated for patients who have combined diseases of both ascending aorta plus aortic arch segments and descending aortic aneurysm. It can also be used for patients with DeBakey type I aortic dissection. Some patients can be cured after the first stage operation.

Angiotensin I-converting enzyme gene polymorphism in Chinese patients with obstructive sleep apnea syndrome.
To investigate the relationship of an insertion/deletion (I/D) polymorphism of the angiotension-converting enzyme (ACE) gene to obstructive sleep apnea syndrome (OSAS) patients and the control subjects. ⋯ These results indicate that the I/I genotype and I allele are a risk factor for OSAS in Chinese.

To evaluate the reproducibility of Thermoscan, an infrared emission detection ear thermometer, and to establish the normal reference range of ear temperature in Chinese neonates. ⋯ Thermoscan produced reproducible results in Chinese neonates. The normal range of ear temperature for Chinese neonates is 35 degrees C to 37 degrees C. Ear temperature > 37.8 degrees C should be regarded as fever.

Comparative StudyMechanical and histological analysis of bone-pedicle screw interface in vivo: titanium versus stainless steel.
To investigate the differences in bone interface between titanium and stainless steel pedicle screws in the lumbar spine. ⋯ Pedicle screws made of titanium have a better bone-screw interface binding than screws made of stainless steel. Torsional tests are more informative for bone-screw interface study. Pull-out tests seem less valuable when comparing bone purchase of screws made from different materials.

Proliferative activity in cervical intraepithelial neoplasia and cervical carcinoma.
To detect the proliferative activity of cervical cells in cervical intraepithelial neoplasia (CIN) and cervical carcinoma by using proliferating cell nuclear antigen (PCNA) immunohistochemistry and mitotic index (MI). ⋯ PCNA and mitotic figure are useful for evaluating proliferative activity in CIN and cervical carcinoma, and could be used to distinguish CIN III from CIN I-II and evaluate the malignant potential of tumour tissues.
