To analyze clinical, neuro-electrophysiologocal, imaging and pathological characteristics of Hirayama disease (HD) and review its relevant literatures to improve its diagnosis. Clinical data of two HD cases admitted to Fujian Provincial Hospital, Fuzhou during 2005 to 2008 were analyzed with literatures review. HD occurred more in males, often onset at their adolescence with muscular weakness and atrophy in one or two upper limbs, but without sensory dysfunction or pyramidal signs. Neuro-electrophysiology showed neurogenic abnormality in the body areas dominated by the 4th cervical vertebra to the 1 st thoracic vertebral (C4-T1) spinal nerves in all the patients. Magnetic resonance imaging (MRI) showed slight atrophy of the lower cervical spinal cord at routine position and its compression and forward displacement to varied extent at flexion position, with posterior epidural capsular space widening, crescent or striped high signal, and voids of vessels in some patients. Enhancement magnetic resonance scanning showed crescent sign enhanced in some patients. Biopsies of the inflicted muscles appeared slight neurogenic abnormality in some cases, and normal in other cases. HD is rarely seen clinically, but it can usually be diagnosed according to its symptoms, neuro-electrophysiology and MRI.

Objective To discuss the feasibility of the lung transplantation as an effective treatment for end-stage pulmonary diseases domestically and to compare the major issues involving the practice of lung transplantation domestically and overseas.Methods After the foundation of group of lung transplantation in May 2002, lung transplantation models of porcine were set up. From September 2002 to April 2005, in the 18 cases undergoing lung transplantation, there were subjected to single-lung transplantion (SLT, 83.3%) and 3 bilateral sequential single lung transplants without CPB (DSSLT, 16.7%). Indications for SLT (n=15) included emphysema (n=9), pulmonary fibrosis (n=3), pneumosilicosis (n=1), lymphangioleiomyomatosis (n=1) and ventricular septal defect (VSD) induced Eisenmenger's syndrome (n=1); for DSSLT (n=3) bronchiectasis (n=1) and pulmonary emphysema (n=2). Among the 15 SLTs, there were 9 cases of left SLT and 6 right SLT. Among them, 2 cases shared one same donor's lung block, one case received contralateral lung transplantation―a left donor lung implanted in the recipient’s right thorax, and one case simultaneous right SLT and VSD repair. Results In hospital mortality (HM) was 3/18 ( 16.7%). Among SLTs, early death was due to severe rejection on the 30th postoperative day in one patient and acute rejection on the 15th postoperative day in other patients, and another patient died due to pulmonary vein embolism on the 36th day. There were 3 and 2 patients with the survival time longer than 1 and 2 years respectively. The median overall survival was 10 (2 to 32) months. Conclusions Our LT program shows similar results to those reported by the International Society for Heart and Lung Transplantation for developed countries. The key of successful operation depends on the establishment of group of lung transplantation and cooperation of multi-department. Ischemic-reperfusion injury, acute-rejection and infection are the major reasons of deaths shortly after the operations.

Objective To assess the efficacy of interventional bronchoscopic techniques used to treat stenosis of bronchial anastomosis after lung transplantation.Methods A retrospective study of 24 cases who underwent lung transplantation from September 2003 to August 2005 in our Unit was done. All recipients were subjected to surveillance bronchoscopy with biopsy at predetermined intervals and when clinically indicated. Endobronchial electrocauterization with microwave therapy apparatus and endobronchial electrocoagulation with high-frequency electrotome were performed for the management of bronchial stenosis or granuloma formation.Results There were 2 of 24 recipients (2/24,8.3 %) with stenosis of bronchial anastomosis. Airway stenosis appeared in 3 of 28 anastomoses (3/28,10.7 %): 2 on the left and 1 on the right. These patients with airway stenosis responded to interventional bronchoscopy,and their respiratory function was improved significantly.Conclusions Despite the improvements in surgical technique and immunosuppression strategies,a small number of patients still had airway complications after lung transplantation. Interventional bronchoscopic techniques,i.e. endobronchial electrocauterization with microwave therapy apparatus and endobronchial electrocoagulation with high-frequency electrotome will be effective in the treatment of airway complications after lung transplantation and with good response in respiratory function.

Objective To observe the therapeutic effect of electroacupuncture (EA) on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training for poststroke lower limb dysfunction. Methods Fifty-two qualified mild hemiplegia cases were randomized into control group A ( N=17) , control group B (N=17), and observation group (N=18 ). Control group A was given conventional rehabilitation training, control group B was given conventional rehabilitation training and task-targeting knee strength-coordination isokinetic muscle strength training based on visual feedback, and observation group was given EA on acupoints located along anterior and posterior thigh muscles plus the treatment for control group B. The treatment for the three groups was performed once a day, five days a week, lasting 3 weeks. Before and after treatment, the lower limb motor function, peak torque ( PT) of knee flexion and extension muscles, and gait speed and gait symmetry were monitored. Results After treatment for 3 weeks, the lower limb motor function, PT and gait symmetry were much improved in the three groups (P<0.05 compared with those before treatment) . Except that the gait speed and lower limb muscle tension of observation group did not differ from those of control group B ( P>0.05) , the improvement of observation indexes of control group B was superior to that of control group A, and the improvement of observation indexes of observation group was more obvious than that of the two control groups ( P<0.05) . Conclusion EA on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training is more effective for improving lower limb motor function of poststroke lower limb dysfunction patients than conventional isokinetic training.

The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage. The results indicate that the effect of arecoline on rat hepaticdoes not involve transcriptional activation of the gene, but largely involves the stabilization of CYP2E1 protein against degradation or increased efficiency of CYP2E1 mRNA translation, and additionally involve the post- ranslational modification of CYP2E1 protein. Furthermore, the CYP2E1 response is fairly equal among the different species, the induction of rat hepatic CYP2E1 by arecoline suggests that there is a risk of metabolic interaction among the substrate drugs of CYP2E1 in betel-quid use human.
