3.Adult dermatomyositis with gastrointestinal bleeding and perforation:a case report and analysis of literature
Chinese Journal of Postgraduates of Medicine 2017;40(7):601-603
Objective To investigate the clinical features and prognosis of adult dermatomyositis with gastrointestinal bleeding and perforation. Methods The clinical data of a adult dermatomyositis with gastrointestinal bleeding and perforation were retrospectively analyzed. And the clinical characteristics of this patient were analyzed, combined with 7 cases reported in the literature. Results Among the 8 cases, 6 cases were females and 2 cases were males, aged 18 to 63 years. The 5 cases had melena, 3 cases had hematemesis, 3 cases had hematochezia and 1 case had hemoptysis. The main treatment was glucocorticoids, immunosuppressive agent, intravenous immune globulin (IVIG), endoscopic hemostasis and angiographic embolization. Four of the 8 cases died. Conclusions Adult dermatomyositis with gastrointestinal bleeding and perforation is rare, but the condition is dangerous and the mortality is high. Dermatomyositis with early onset of abdominal pain, vomiting, melena should be alert to serious complications such as gastrointestinal bleeding and perforation.
6.Changes of axonal count of white matter and recovery of motor function induced by nerve growth factor in rats with spinal cord injury
Chinese Journal of Tissue Engineering Research 2007;11(6):1192-1194
BACKGROUND:Neurotrophic factors have been conformed to have the effects of promoting the survival, differentiation and axonal regeneration of the injured neurons, so that the structural integrity of the injured spinal cord can be reserved as much as possible.OBJECTIVE: To observe the effects of nerve growth factor (NGF) on the neural regeneration and motor function following spinal cord injury in rats.DESIGN: A randomized controlled observation.SETTING: Department of Neurology, Union Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: Thirty healthy adult male Wistar rats of common degree, were provided by the Experimental Animal Center, Tongji Medical College of Huazhong University of Science and Technology.METHODS:The experiment was carried out in the Department of Neurology, Union Hospital of Tongji Medical College,Huazhong University of Science and Technology. The 30 rats were randomly divided into NGF-treated group (n=15) and control group (n=15). ① T8 spinal injury was induced by the improved Allen method. ③ The improved Rivlin method (namely, slope test) was used to assess the motor function following spinal cord injury in rats before model establishment and at 3 days, 1, 2 and 3 weeks after treatment respectively. ④ At 2 days and 3 weeks postoperatively, 7 rats in the NGF-treated group and 8 rats in the control group were selated and the cross-sectional tissue(0.5 cm) of the injured spinal cord was removed, fixed in neutral formalin, dehydrated, and embedded with paraffin, and then cut into 5 μm sections.MAIN OUTCOME MEASURES:① The results of the slope test before model establishment and at 3 days,1, 2 and 3weeks after treatment respectively; ② Axonal count in white matter at 2 days and 3 weeks after model establishment.RESULTS:① The scores of slope test after spinal cord injury at 1, 2 and 3 weeks postoperatively in the NGF-treated group were obviously higher than those in the control group [(45.2±3.2), (51.2±3.8), (53.4±4.6)°; (45.2±3.2), (51.2±3.8),(53.4±4.6)°, P < 0.05].② At 3 weeks after treatment, a few dispersal and heterogeneous NGF200 spots were observed in the white matter of rats in the control group, but there were plentiful and symmetrical NGF200 spots in the NGF-treated group. The axonal count in white matter at 3 weeks following spinal cord injury in the NGF-treated group was obviously higher than that in the control group (363.6±34.2, 187.5±32.1, P< 0.05).CONCLUSION:NGF can promote the neural regeneration following spinal cord injury to a certain extent, and help to im prove the functional recovery.
7.Obstructive sleep apnea as an independent risk factor for stroke: possible mechanislms
International Journal of Cerebrovascular Diseases 2011;19(12):911-915
Obstructive sleep apnea (OSA),the most common type of sleep disordered breathing was closely associated with the occurrence of ischemic stroke.It has been demonstrated that OSA is an independent risk factor for ischemic stroke.Its pathogenic mechanism includes atherosclerosis,coagulation abnormalities and cerebral hemodynamic changes caused by long-term periodic hypoxia hypoxemia and hypercapnia.The prognosis of ischemic stroke patients with OSA is poor.Therefore,it needs to be treated early to avoid further damage to brain tissue and reduce the mortality.
8.Application development of magnetic nanoparticles in cancer diagnose and therapy
International Journal of Biomedical Engineering 2016;39(2):120-125
Cancer is one of the three major killers that threatened human health in the twenty-first century,making the early diagnose and high-efficiency therapy crucial.The recent-developed nanotechnology brings new hope for this.Among different nanomaterials,magnetic nanoparticles show positive effects in diagnosis and therapies since they can be located with certain magnetic fields and can vibrate and heat up in the alternating magnetic field.With the ever increasing attention paid to the study,magnetic nanoparticles will play a key role in cancer diagnosis and therapy.This review gives a comprehensive discussion on development of the research and applications of magnetic nanoparticles,including single metallic,double metallic and alloyed magnetic nanoparticles.Moreover,it also prospects the future developing orientations of magnetic nanotechnology.Magnetic nanoparticles are widely used these days,with a speedy research development both in theory and application.However,the investigations into the toxicity of magnetic nanoparticles and the medical and commercial standards have to continue before magnetic nanoparticles are determined as valid and with low toxicity.
