颅内室管膜下瘤2例报告

目前，室管膜下瘤的组织学起源仍不明确。但很可能来源于室管膜下层的胶质细胞。此类肿瘤呈膨胀性生长．是生长缓慢、非侵袭性的一种低级别胶质瘤，有症状者非常少见．至今国内外文献报道的有症状病例仅百余例。本文报道了我科收治的2例颅内室管膜下瘤患者的临床特点、影像学特点、和手术治疗效果。     

Multiple aneurysms in Beh?et's disease

Beh?et's disease is characterized by recurrent ulcers of the mouth and genitalia and relapsing iritis. It is now recognized as a chronic multisystem disease affecting the skin, mucous membranes, eye, joints, central nervous system, and blood vessels. One of the known vascular complications of Beh?et's disease is aneurysm formation or venous thrombosis. The two patients with Beh?et's disease in this report developed multiple aneurysms over a short time span. Vascular surgeons dealing with young adults with peripheral aneurysms must be aware of this uncommon yet challenging clinical entity.     

Whole CanA Gene Amplification of Helicobacter pylori and Its Fingerprinting by Restriction Fragment Length Polymorphism

To set up a method of amplification for the whole CagA gene of Helicobacter pylori and its fingerprinting by restriction fragment length polymorphism(RFLP),nested PCR was employed in combination with TD-PCR to amplify the gene and EcoRI and Hind Ⅲ were used to generate the RFLP fingerprinting.Target DNA fragments from 13 of 20 samples were successfully amplified and the relevant RFLP fingerprintings were obtained.It is concluded that the method can be used to amplify the whole CagA gene and CagA gene has apparent diversity of RFLP profile.     

Regional anaesthesia in ambulatory surgery

Regional anaesthesia provides many advantages and can be practised safely in ambulatory surgery. It provides better postoperative pain control, avoids many complications associated with general anaesthesia and shortens recovery time. However, extra time required, associated complications and acceptance of patients are the factors of concern in practising regional anaesthesia in an ambulatory setting. This review will discuss various regional anaesthesia techniques suitable for outpatients.     

骨骼肌钝挫伤后愈合质量的肌电评价

目的 :观察大鼠骨骼肌钝挫伤后 ,不同干预方法对骨骼肌修复过程中肌电信号的影响 ,研究肌电图在骨骼肌损伤愈合过程中的评价作用。方法 :10 8只雄性SD大鼠 ,利用自制的重物坠落打击装置造成右侧腓肠肌钝挫伤。随机分成 3组 ,即胰岛素样生长因子 - 1(IGF - 1)组、中药组和自然愈合组 ,分别于损伤局部注射IGF - 1、黄芪丹参注射液、不作处理。于伤后第 2、5、7、10、14、2 1、2 8、35、5 6天观察并比较双侧腓肠肌的肌电图变化 ,记录纤颤电位和正尖波等自发活动 ,分析复合肌肉动作电位 (CMAP)并测量其潜伏期和波幅 ,观察伤后CMAP的变化。结果 :(1)各组大鼠均于伤后第 2～ 5天出现纤颤电位和正尖波 ,约至第 7～ 10天达到高峰 ,然后逐渐减少。以IGF - 1组最早消失 ,中药组次之。 (2 )各组大鼠的伤侧肌电图CMAP中的潜伏期逐渐缩短 ,波幅逐渐增高。以IGF - 1组最快 ,中药组次之 ,自然愈合组最慢。 (3)伤后第 8周 ,IGF - 1组和中药组大鼠损伤侧CMAP波幅接近正常 ,自然愈合组则显著低于其它两组。结论 :(1)肌电图检测证实 ,IGF - 1和黄芪丹参注射液均具有促进骨骼肌损伤愈合的作用 ,但以IGF - 1的作用更明显。 (2 )损伤肌肉局部肌电信号的变化 ,可以用来评价损伤骨骼肌的修复进程和愈合质量

In vitro differentiation of human adipose-derived adult stromal cells into neuron-like cells in hippocampal astrocyte conditioned medium

BACKGROUND: At present, researches on differentiating from human adipose-derived adult stromal cells (hADASC) to neuron-like cells are focus on inducing by artificial-synthetic compound solution; however, hippocampal astrocyte conditioned medium (HCAM) can induce in vitro differentiation from hADASC to neuron-like cells is still unclear. OBJECTIVE: To observe whether HCAM can induce in vitro differentiation from hADASC to neuron-like cells. DESIGN: Randomized control study. SETTING: Department of Neurology, Taixing People's Hospital; Central Laboratory, North China Coal Medical College. MATERIALS: Donor of adipose tissue was donated by female volunteers suffering from caesarean section in the department of obstetrics & gynecology in our hospital and aged 20－35 years. Adipose tissue was collected from subcutaneous tissue of abdomen during the operation. In addition, 8 male newborn Wistar rats within 24 hours with average body mass of 20 g were provided by Animal Institute of Chinese Academy of Medical Sciences. Rabbit-anti-human Nestin polyclonal antibody, rabbit-anti-human glial fibriliary acidic protein (GFAP) polyclonal antibody, rabbit-anti-human neuro-specific enolase polyclonal antibody and mouse-anti-human microtubal associated protein 2 (MAP-2) polyclonal antibody were provided by Wuhan Boster Company. METHODS: The experiment was carried out in the Central Laboratory of North China Coal Medical College from October 2004 to June 2005. hADASC was cultured with HCAM and its growth and morphological changes were observed under inverted phase contrast microscope. Immunocytochemistry, immunofluorescence and Western blotting were used to evaluate the expressions of Nestin, which was a specific sign of nerve precursor, neuro-specific enolase and MAP-2, which was a specific sign of nerve cell, and GFAP, which was a specific sign of neuroglial cells. MAIN OUTCOME MEASURES: Nestin, which was a specific sign of nerve precursor, neuro-specific enolase and MAP-2, which was a specific sign of nerve cell, and GFAP, which was a specific sign of neuroglial cells. RESULTS: On the 3rd day of culture, partial hADASC started deformation from slender shuttle-shape cells to neuron-like cells. It suggested that cells stretched out apophysis, which were mainly double-pole or multiple-pole cells. Five days later, immunohistochemical detection suggested that expression of Nestin (10.5±0.037) was found out in cells; meanwhile, expressions of GFAP (38.4±0.052) and neuro-specific enolase (NSE) (15.7±0.023) were also found out in cells; however, expression of MAP-2 was not observed. Western blot indicated that, 5 days after effect of HCAM, Nestin was found out in hADASC; meanwhile, expressions of GFAP and neuro-specific enolase were also found out; however, expression of MAP-2 was not observed. CONCLUSION: HCAM can induce the differentiation from hADASC to neuron-like cells in vitro.
