卵巢切除对鼠椎体骨形态学的影响

3月龄成熟SD大鼠踮只，随机分卵巢切除组(oVX)及假手术组(ShamO)，切除双侧卵巢或作假手术。术后1，3，5，7月时各分别处死，刮取出第4、5腰椎体，进行光镜、透射电镜、扫描电镜观察。发现OVX后椎体皮质骨及终板变薄，巾央区小梁稀少、变细、吸收、穿孔、中断，水平连结小梁丧失，骨小梁胶原排列明显不规则甚至断裂，并可见较多骨小梁显微骨折及细微骨痂结构。大量功能活跃的破骨细胞出现，成骨细胞功能相对减退，向骨细胞转化。提示OVX后骨小梁的结构强度明显下降，椎体的力学强度降低。     

Dexmedetomidine supplemented with local anesthesia for awake laryngoplasty

Certain laryngeal procedures require a sedated patient who is responsive to allow for the assessment of vocalization. Dexmedetomidine as a single agent for sedation and anxiolysis for awake laryngoplasty in a patient with unilateral vocal fold paralysis is presented.     

The Lautenbach method for chronic osteomyelitis: nursing roles, responsibilities and challenges

Osteomyelitis is serious for both the orthopaedic surgeon and the patient. Bone infection is very difficult to treat and if not eradicated has long-term effects for the patient. The current techniques available have a low success rate and sometimes the only alternative is amputation.This article discusses:

• What is bone infection and how it effects a person's life

• Existing methods of treatment and compares them with the Lautenbach method

• Pre, peri and post-operative care of patients undergoing the Lautenbach method of treatment

• A case study to illustrate how the method was used to successfully treat a patient.

丹参对肢体缺血再灌注损伤的保护作用（动物实验）

用兔造成肢体缺血再灌注损伤动物模型,用丹参液予以治疗。结果表明用药后血MDA、CPK、GOT值较对照组明显下降(P<0.05),电镜下骨骼肌细胞损害也轻于对照组。说明丹参可抑制氧自由基产生并减轻骨骼肌细胞损害,对肢体缺血再灌注损伤有保护作用。     

The treatment of pediatric supracondylar humerus fractures

Based on the best current evidence and a systematic review of published studies, 14 recommendations have been created to guide clinical practice and management of supracondylar fractures of the humerus in children. Two each of these recommendations are graded Weak and Consensus; eight are graded Inconclusive. The two Moderate recommendations include nonsurgical immobilization for acute or nondisplaced fractures of the humerus or posterior fat pad sign, and closed reduction with pin fixation for displaced type II and III and displaced flexion fractures.
