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.

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.

Objective To evaluate the change of left ventricular(LV) function by real-time three dimensional echocardiography(RT-3DE) and to explore the clinical value of change of serum adiponectin level in patients with metabolic syndrome (MS).Methods One hundred and twenty patients were divided into MS group and control group according to the diagnostic standard of the nternational Diabetes Federation.Transthorasic 2D ultrasound and RT-3DE examination were performed in all study objects, and serum adiponectin levels were measured.Results Parameter index [including Tmsv16-SD, Tmsv12-SD,Tmsv16- Dif, Tmsv12-Dif, Tmsv16-SD (％), Tmsv 12-SD (％), Tmsv16-Dif (％), Tmsv12-Dif (％)] of 17segment time to minimal systolic volume in MS group was more than that in control group (all P ＜0.05).Some regional systolic index of LV and serum adiponectin level were less than that in control group (all P ＜0.05).Compared with the control group, E/E' was lower (P ＜ 0.05).There were significant relations between serum adiponectin level and E/A of mitral valves, E'/A' of mitral annulus and E/E'(r = 0.368,0.493,and -0.347 respectively, P ＜0.05).Conclusions RT-3DE can rapidly evaluate LV systolic and diastolic synchrony in MS patients.E/E' show an excellent correlation with serum adiponectin level,and it may be a new promising method for routine evaluation of LV diastolic function.

An isocratic high-performance liquid-chromatographic method is-described for the simultaneously determining carbamazepine and its biologically active metabolite, carbamazepine-10, 11-epoxide. Serum samples containing an internal standard (10-methoxycarba-mazepine) are extracted with dichlor-methane and 4 mol ? L-1 sodium hydroxide. The organic extract are evaporated at ambient temperature under a stream of nitrogen. The residues are reconstituted in mobile phase and injected on to a re-versed-phase C18 Column (150?4. 6mm I. D). The mobile phase consists of ace-tontrile/methanol/water (50/210/260 by vol) . The UV detector is operated at 214nm. The elution times of all com-pounds are within 7 min.The least detectable concentrations of carbamazepine and carbamazepine-10, 11-epoxide are 0. 08mg ? L-1 and 0.1mg ? L-1, respectively. The average absolute recovery for carbamazepine is 96.0% and for carbamazepine-10,11-epoxide is 97.3%. Within-run CV is 3. 3%~5.7%. and between-run CV is 4.3%~9.0%. The standard curve is linear at least within 40mg ? L-1 for carbamazepine and within 20mg ? L-1 for carbamazepine-10, 11-epoxide.

Objective To explore the measure to diminish the misdiagnosis of Budd-Chiari syndrome.Methods 46 cases of Budd-Chiari syndrome were analyzed.Results 33 cases had ever been misdiagnosed with average time of 5.3 years.One of the main clinical symptoms was the pathological process of lower limb(84.8%).Doppler color flow imaging examination showed positive rate of 100% in liver veins and inferior vena cava,,but none of the misdiagnosed cases received this examination.The viral marker test had a positive rate of only 4.3% that was not higher than that of general population.Conclusion Budd-Chiari syndrome has a variety of symptoms,so Doppler color flow imaging is considered an important means to diagnose this disease.

Cushing's syndrome is caused by the excessive secretion of cortisol from the adrenal cortex.Hypertension is one of the most distinguishing features of Cushing's syndrome,as it is present in about 80% of adult patients.The various pathogenetic mechanisms that have been proposed for the development of cortisol-induced hypertension in Cushing's syndrome and its management are discussed.

Objective To explore the examination methods about stability of carotid atherosclerotic plaque and evaluate the curative effect of medicine on carotid atherosclerosis.Methods 150 patients with carotid atherosclerotic plaque in acute stage ischemic stroke were divided into treatment group and control group at random.Stable or instable plaques were assessed and carotid artery intima-media thickness(IMT) were measured according to the characteristics of carotid atherosclerotic plaque on supersound imagin.The treatment in treatment group were different from that in control group.The therapeutic efficacy was observed respectively.Results After the treatment 1 month and 3 months,in treatment group carotid artery IMT decreaced more than that at accidence of treatment group and that of control group,the carotid atherosclerotic plaques stabilizese increasingly.Conclusion The stability of carotid atherosclerotic plaque may be evaluated through the ultrasound imagin.Statin and aspirin can lighten carotid atherosclerosis and stabilize the plaque.
