Upper thoracic spine lesions are characterized by delayed diagnosis due to nonspecific symptoms and its anterior aspect (T1 - T4) is difficult to be approached surgically. This retrospective clinical study was done to assess the efficacy of mini thoracotomy approach in management of these lesions. We studied 14 cases with upper thoracic spine different pathological lesions at levels (T1 - T4). These lesions were indicated for anterior approach surgery. Radiological assessment included plain X-ray, MRI and CT scan thoracic spine. The anaesthesia was specifically selective intubation and unilateral ventilation. All patients were operated upon through mini inter-costal thoracotomy approach (left sided in 13 patients and right sided in 1patient). Out of 14 patients there were 7 males and 7 females. The age range was 20 - 55 years (mean 38.7 years). Preoperative symptoms included vague nonspecific upper thoracic pain in 11 patients, lower limbs weakness in 6 patients, sphincteric disturbance in 5 patients, upper thoracic kyphotic deformity in 4 patients, severe brachialgia in 3 patients and neck pain in 2 cases. The operative time was ranged from 90 - 210 minutes (mean 152 m). Blood loss ranged from 250 to 750 cc (mean 464 cc). Chest tube drainage was inserted in all patients. There were no intra-operative or post-operative surgically related complications and no patients needed ICU admission. The lesions were neoplasms in 8 patients, traumatic fracture dislocation in 3 cases, tuberculous spondylodiscitis in 2 cases and degenerative disc prolapse in 1 case. All patients improved post-operative as regard their pre-operative complaints except one patient. During the follow up period, no mortality was recorded. In conclusion, mini thoracotomy approach seems to be ideal only for patients with mono- or bi-segmental pathology involving the upper thoracic spine. 展开更多

鱼类年龄的准确鉴定是研究鱼类生态学和保护生物学的基础。本文对黄河上游花斑裸鲤(Gymnocypris eckloni)耳石、背鳍条和臀鳞等3种年龄材料的年龄解释一致性以及最佳年龄材料的选择进行了比较和分析,并首次建立了花斑裸鲤低龄个体年... 鱼类年龄的准确鉴定是研究鱼类生态学和保护生物学的基础。本文对黄河上游花斑裸鲤(Gymnocypris eckloni)耳石、背鳍条和臀鳞等3种年龄材料的年龄解释一致性以及最佳年龄材料的选择进行了比较和分析,并首次建立了花斑裸鲤低龄个体年龄判别方程。结果表明:花斑裸鲤3种年龄材料上年轮可读性依次是耳石〉背鳍条〉臀鳞,最大鉴定年龄分别为25龄、17龄和16龄;对于6龄及以下个体,背鳍条作为年龄鉴定材料更有优势;对7龄及以上个体,耳石效果最佳;同时对6龄及以下个体以全长、体长、体重和空壳重为自变量,采用逐步选择法进行判别分析,最终提取全长和体重建立年龄的分类函数;全部样本正判率和交叉验证正判率显示,该年龄判别模型的正确区分度较高,可用于6龄及以下个体(全长93~259 mm;体重6.25~177.10 g)的年龄判别。 展开更多
