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.     

慢性高输出量型心功能不全发展过程中心室舒、缩功能和顺应性的变化及其与心泵功能的关系

本文研究了大鼠慢性高输出量型心功能不全发展过程中心室舒,缩功能和顺应性的变化规律及其与心泵功能的关系。疾病模型采用动静脉造瘘(ACF)加单侧肾动脉缩窄(RAS)的方法建立。本实验中,全部ACF+RAS大鼠均呈现出慢性高输出量型心功能不全的特征,在静息状态下心脏指数(CI)显著升高,而心泵贮备功能(CORF)却不同程度地降低。结果表明:随心泵功能的恶化,心室的舒、缩功能进行性降低,心室的舒张顺应性显著升高,心室的舒,缩性能和顺应性在心功能不全发展的不同阶段对心泵功能所起的作用不同。     

原发女性乳腺癌术后生存率的改善

目的：女性原发乳腺癌术后生存率是否随时间进展有所改善,学术界曾有争论。一些学者认为有而另些则认为无。本文通过对天津肿瘤医院收治的乳腺癌进行回顾性研究。比较不同时期的生存率,并与欧美国家同期比较,企图说明天津肿瘤医院治疗乳腺癌技术不断提高,以及在国际所处的位置。方法：1954年至1984年间,天津肿瘤医院收治原发女性乳腺癌4491例,重新复习病历,按UIEC标准（1987）重新分期,全部病人随访5－15a,将病历资料输入计算机统计分析。结果：50年代,5a,10a和15a的生存率分别为48．4％,37．3％和30．8％;60年代为62．5％,50．9％和43．9％,70年代为69．9％、59．8％和50．7％,80年代仅有5a生存率为79．0％。结论：说明从50年代至80年代乳腺癌术后生存率明显提高。这一结果与美国白人及欧洲生存率最高的国家相同。

NAc Shell Arc/Arg3.1 Protein Mediates Reconsolidation of Morphine CPP by Increased GluR1 Cell Surface Expression: Activation of ERK-Coupled CREB is Required

Background:

Relapse into drug abuse evoked by reexposure to the drug-associated context has been a primary problem in the treatment of drug addiction. Disrupting the reconsolidation of drug-related context memory would therefore limit the relapse susceptibility.

Methods:

Morphine conditioned place preference (CPP) was used to assess activity-regulated cytoskeleton-associated protein (Arc/Arg3.1) and correlative molecule expression in the Nucleus accumbens (NAc) shell during the reconsolidation of morphine CPP. U0126 and Arc/Arg3.1 antisense oligodeoxynucleotide were adapted to evaluate the role and the underlying mechanism of Arc/Arg3.1 during the reconsolidation.

Results:

The retrieval of morphine CPP in rats specifically increased the Arc/Arg3.1 protein level in the NAc shell, accompanied simultaneously by increases in the phosphorylation of extracellular signal-regulated kinase1/2 (pERK1/2), the phosphorylation of Cyclic Adenosine monophosphate (cAMP) response element-binding (pCREB), and the up-regulation of the membrane α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptors GluR1 subunit level. Intra-NAc shell infusion U0126, an inhibitor of the Mitogen-activated protein kinase kinase (MEK), prevented the retrieval-induced up-regulation of pERK1/2, pCREB, Arc/Arg3.1, and membrane GluR1 immediately after retrieval of morphine CPP. The effect of disrupting the reconsolidation of morphine CPP by U0126 could last for at least 14 days, and could not be evoked by a priming injection of morphine. Furthermore, the specific knockdown of Arc/Arg3.1 in the NAc shell decreased the membrane GluR1 level, and impaired both the reconsolidation and the reinstatement of morphine CPP.

Conclusions:

Arc/Arg3.1 in the NAc shell mediates the reconsolidation of morphine-associated context memory via up-regulating the level of membrane of GluR1, for which the local activation of the ERK-CREB signal pathway, as an upstream mechanism of Arc/Arg3.1, is required.
