Subscapularis Transthoracic Versus Posterolateral Approaches in the Surgical Management of Upper Thoracic Tuberculosis: A Prospective,Randomized Controlled Study

The objective of the present study was to evaluate the clinical, radiological, and functional outcomes of a subscapularis transthoracic surgical approach and a posterolateral surgical approach with debridement, bone graft fusion, and internal fixation for the treatment of upper thoracic tuberculosis.There is currently debate over the best surgical approach for the treatment of upper thoracic tuberculosis. Traditionally, the subscapularis transthoracic approach has been preferred; however, the posterolateral approach has gained popularity in the past few years.A prospective, consecutive cohort of 43 upper thoracic tuberculosis patients with a mean age of 39 years (range: 20–52 years) was followed up for a minimum of 12 months (range: 12–60 months). Patients were randomly divided into 2 groups. Group A (n = 21) was treated by the subscapularis transthoracic approach and group B (n = 22) was treated by the posterolateral approach. All cases were evaluated for clinical, radiological, and functional outcomes. Intraoperative blood loss, operative duration, intraoperative and postoperative complications, hospital stay, the cure rate, fusion time, and the Frankel scale were used for clinical and functional evaluation, whereas the kyphosis angle was used for radiological evaluation.Grafted bones were fused by 10 months in all cases. There was no statistically significant difference between groups before surgery in terms of gender, age, segmental tuberculosis, erythrocyte sedimentation rate (ESR), Frankel scale, or Cobb''s angle (P > 0.05). The average operative duration for Group B was lower than that of Group A. There were no significant differences in intraoperative blood loss, intraoperative and postoperative complications, hospital stay, grafted bone fusion time, or cure rate between groups (P > 0.05). The Cobb''s angle correction rate for group B (68.5%) was significantly better than that of group A (30.9%). The neurological score showed significant postoperative improvement in both groups, with no significant difference between the groups.The subscapularis transthoracic approach and the posterolateral approach with debridement, bone graft fusion, and internal fixation are both sufficient and satisfactory for the surgical treatment of upper thoracic tuberculosis. However, the posterolateral approach is superior to the subscapularis transthoracic approach in terms of surgical trauma, operative time, and kyphosis correction.     

慢性强迫游泳应激对大鼠情绪和脑细胞外信号调节激酶磷酸化水平的影响

目的探讨慢性强迫游泳应激对大鼠情绪和脑细胞外信号调节激酶磷酸化(P-ERK1/2)水平的影响。方法将30只SD雄性大鼠随机分为游泳应激组、装置对照组和空白对照组,每组10只。游泳应激组每天接受5min的游泳应激,装置对照组每天接受5min的新异场景应激,均连续14 d,空白对照组不进行任何干预,然后观察大鼠行为(体质量增长量、旷场测验和糖精水溶液偏好测验)。采用免疫印迹法测定大鼠海马和前额叶皮质的P-ERK1/2。结果(1)游泳应激组在应激7d和应激14d的体质量增长[分别为(75±22)g和(70±24)g]均低于空白对照组[分别为(101±35)g和(115+47)g],均P＜0.05。(2)装置对照组的粪便排泄量[(1.4±1.9)粒]多于空白对照组[(0.4±1.0)粒]和游泳应激组[(0.1±0.3)粒],均P＜0.05；而游泳应激组的水平活动距离[(2077±1245)cm]少于空白对照组[(2990±1038)cm]和装置对照组[(3110±1462)cm],均P＜0.05。(3)游泳应激组的糖精水溶液摄入量[(11±6)g]和糖精水溶液摄入量占总液体摄入量的比例[(37±16)％]均低于空白对照组[分别为(15±4)g和(47±15)％],均P＜0.05。(4)游泳应激组在海马[(46±95)％]和前额叶皮质[(65±24)％]的P-ERK2水平均低于空白对照组[分别为(76±30)%和(99±42)%],均P＜0．05。结论慢性强迫游泳应激能诱发大鼠的抑郁情绪,降低P-ERK2在海马和前额叶皮质的水平。

端粒酶逆转录酶、环氧化酶-2在乳腺癌中的表达及其意义

目的 探讨端粒酶逆转录酶(hTERT)和环氧化酶(cox)-2在乳腺浸润性导管癌中的表达及其临床意义.方法 使用免疫组织化学法分别检测45例乳腺浸润性导管癌和22例乳腺良性病变标本的hTERT和COX-2蛋白表达情况.结果 hTERT在乳腺浸润性导管癌中阳性表达率fig71.11%,明显高于乳腺良性病变9.09%,两者比较差异有统计学意义(P<0.05).hTERT阳性表达与乳腺浸润性导管癌患者的年龄、肿瘤大小、腋窝淋巴结转移情况及雌、孕激素表达水平无相关性(P>0.05),与Her-2表达存在显著相关性(P<0.05).COX-2在乳腺浸润性导管癌中的阳性表达率为82.22%,明显高于乳腺良性病变50.00%,两者比较差异有统计学意义(P<0.05).COX-2阳性表达与乳腺浸润性导管癌患者腋窝淋巴结转移情况、Her-2、ER阳性表达有关(P<0.05).在乳腺浸润性导管癌中hTERT阳性表达与COX-2阳性表达呈正相关(r=0.557,P<0.01).结论 hTERT与COX-2在乳腺浸润性导管癌中的表达显著高于在乳腺良性病变中的表达,hTERT与COX-2在乳腺癌的发生、发展中起重要作用.hTERT表达与COX-2表达存在显著相关性,COX-2的过度表达可能是端粒酶激活和调节的机制之一.
