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 analyze the diagnosis and treatment of airway stenosis in a consecutive series of bronchial anastomosis after lung transplantation in our center.Methods We performed a retrospective study on 100 cases of lung transplants in our center from September 2002 to December 2010.Seventy-two cases were subjected to single lung transplants (SLT), and twenty-eight to bilateral sequential single lung transplantation (BSSLT). There were totally 128 bronchial anastomoses.All recipients received long-term follow-up to monitor the lung function.Lung CT and fibrobronchoscopic examinations were done when necessary. Results Twenty-five cases with 37 bronchial anatomoses were died.A total of 12 airway stenosis occurred in 10 cases (12/128,9.4 %).Four cases underwent telescopic anastomosis and 6 cases underwent end-to-end anastamosis.Mean diagnosis time was 60.1 35.6 days post-operation (ranging from 15-120 days,median 59 days).There were 8 cases of unilateral airway stenosis (3 on the left,and 5 on the right) and 2 cases of bilateral airway stenosis.The number of simple airway stenosis was 3,that of exophytie granulation tissue was 8,and that of bronchus intermedius stenosis was 1.Culture of bacteria by fibrobronchoscopy with protected specimen brush revealed:3 strains of Pseudomonas aeruginosa,2 strains of Klebsiella pneumoniae,2 strains of Aspergillus,1 strain of Escherichia Coli. 10 cases were treated with fiberoptic bronchoscopic balloon dilation:5 cases with high-frequency electrotome,4 cases with stent placement,and 1 case with argon plasma coagulation (APC).Seven cases were cured or improved and 3 cases died.Conclusion Airway stenosis after lung transplantation remains a major problem.The fiberoptic bronchoscopic procedure is the gold standard to diagnose. The preferred treatment is fiberoptic bronchoscopic balloon under expansion,and other approaches include high-frequency electrotome,APC and stem placement,etc.

The aim of this paper is to compare the cytotoxicity and cellular uptake efficiency of three kinds of poly(b-benzyl-L-amino) block-poly(ethylene glycol) nanoparticles (PXA-PEG-NPs) using Calu-3 cells, and select one as a nasal drug delivery vector for curcumin (Cur). Poly(gamma-benzyl-L-glutamate) block-poly(ethylene glycol) nanoparticles (PBLG-PEG-NPs), poly(gamma-benzyl-L-lysine) block-poly(ethyleneglycol) nanoparticles (PZLL-PEG-NPs) and poly(gamma-benzyl-L-aspartate) block-poly(ethylene glycol) nanoparticles (PBLA-PEG-NPs) were prepared by emulsion-solvent evaporation method. MTT assays were used to evaluate the cytotoxicity of PXA-PEG-NPs against Calu-3 cells. The cellular uptake of nanoparticles was visualized by an inverted fluorescence microscope and quantified by a flow cytometer. The results indicated that even at high concentration of 2 mg x mL(-1) the three nanoparticles had no cytotoxicity on Calu-3 cells. Compared to the curcumin solution, the three curcumin-loaded PXA-PEG-NPs showed significantly higher cellular uptake efficiency on Calu-3 cells (at equal concentration of curcumin with 5 microg x mL(-1) Cur solution), PBLG-PEG-NPs group was the highest. The cellular uptake increased with incubation time, and has positive correlation with nanoparticle concentration. In brief, PXA-PEG-NPs are conducive to delivery Cur into cells, and PBLG-PEG-NPs might be provided as a good nasal drug delivery carrier.
