Objective To report the clinical, myopathological and genetic features in myofibrillar myopathy (MFM) with numerous cytoplasmatic-spheroid bodies. Methods Ten patients in 5 successive generations began to present progressive proximal limbs weakness at 35 to 40 years old. Additionally, 4 cases manifested diarrhea and 6 cases accompanied with cardiorespiratory symptoms. An open biopsy was performed on the proband. In addition to histological, enzymhistochemical staining and ultrastructural examination, immunohistochemical staining with antibody against tau, desmin, ubiquitin, dysferlin, dystrophin-C', dystrophin-N' and dystrophin-R were done. All the exons of the MYOT, CRYAB, DESMIN, LDB3, LMNA, SEPNI gene and the FLNC exon 48 were analysed. Results Cytoplasmatic bodies and spheroid bodies were found in the fibers. The deposited material were positive for tau, desmin, ubiquitin, dysferlin and dystrophin-R, dystrophin-C'. Electron microscope showed granular dense Z-disc material in the inclusions which were surrounded by thin filament. There was no mutation in the above exons of the 7 candidate genes. Conclusions Myofibrillar myopathy involves multiple system impairment. Cytoplasmatic and spheroid bodies contain microtubule and membrane associated protein. The disease might be induced by some unknown genetic abnormities.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.

Objective To report clinical and pathological features in a Chinese family with desminopathy caused by a novel mutation in desmin gene. Methods There were 8 patients (7 male and 1 female) in a family manifesting desminopathy in an autosomal dominant inheritance pattern. The onset age ranged from 20--50 years old. Heart disease appeared in 7 cases, diarrhea in 1 case and limb weakness in 3 patients. Muscle biopsies were carried out in proband and his elder brother. The histological, enzymhistochemicai staining, ultrastructural examination and immunohistochemical staining with desmin antibody were performed. The sequence of desmin gene was analyzed in DNA from 4 patients, 5 asymptomatic members and 50 healthy controls. Results Muscle pathology in the proband revealed wide variation in size of fibers. Some fibers had eosinophilic changes with rimmed vacuoles. Muscle pathology in the brother revealed multiple small and round eosinophilic inclusions in the fibers. Desmin staining was positive in the inclusions and in the sarcolemma. Electron microscopy revealed deposits of abnormal granulofilamentous materials. A novel S12F mutation in desmin gene has been identified in 4 affected family individuals, but not in unaffected family members and controls. Conclusions The desminopathy caused by desmiu SI2F mutation dominantly affected male individuals. Most of victims had cardiac abnormalities. The myopatholgical features can vary in the different patients in one family.
