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.

Objective To define the significance of the anatomical division and features of popliteal artery in popliteal angioplasty.Methods This study involved 118 lower limbs in 113 cases of femoropoliteal occlusive disease undergoing angioplasty in our center between August 2011 and July 2013.A bent-knee angiogram was taken before recanalization of the lesion.The flexion pattern and the location of flexion points of popliteal artery were collected to study their relationship with the division of popliteal artery.A post-procedural bent-knee angiogram was taken in case of popliteal stenting to assess any change in flexion angulation and distal flow.Results There are diverse flexion patterns in popliteal artery,75.4％ of the flexion points locate in P2 segment,18.6％ in P1,and 6.0％ in P3.On post-procedural bent-knee angiogram in 73 cases of popliteal stenting,10 had a more acute distal flexion angulation,distal artery kinking was observed in another 6 cases of which 5 had compromised distal flow.Artery kinking only occurred in cross-flexion-point stenting.Conclusions A better understanding of the division and anatomical features of popliteal artery can be obtained via bent-knee angiogram.This is of value to angioplasty for lesions in different popliteal divisions.

Objective To demonstrate the frequency changes in immune cells on secreting interleukin-10 (IL-10),interferon-? (IFN-?),tumor necrosis factor-? (TNF-?) and interleukin-4 (IL-4) under the stimulation of a mimic 7-amino acid peptide of HCV HVR1 (7P),and to explore the mechanism of such changes. Methods The peripheral blood mononuclear cells (PBMCs) were isolated from healthy people and co-cultured with 7P. Intracellular cytokine staining was performed using antibodies against IL-10,IFN-?,TNF-? and IL-4. The related cells were harvested on a FACSCalibur flow cytometer,and then analyzed with FACSCalibur software. Results Compared to the controls,the frequency of immune cells secreting IFN-? was significantly increased in both CD4+CD8-,CD4-CD8+ T cells and NK,NKT cells (P

AIM:To evaluate the efficacy and safety of methazolamide in treating refractory uveitic macular edema.METHODS: Retrospective self-controlled study was designed.A total of 15 patients (20 eyes) with refractory uveitic macular edema which used methazolamide as adjuvant therapy were enrolled in Shanghai First People`s Hospital from January 2015 to June 2016.The changes of central macular thickness (CMT) and best corrected visual acuity (BCVA) were observed at baseline and 2, 4, 8wk after treatment.We also focused on the incidence of complications and relapse.RESULTS: The CMT was 445.95±154.10μm, 338.83±138.34μm, 251.50±40.20μm, 244.90±35.68μm at baseline, 2, 4 and 8wk after treatment, respectively.The differences among them were statistically significant (F=15.467, P<0.05).The BCVA (log MAR) were 0.40±0.17, 0.28±0.21, 0.19±0.20, 0.18±0.21 at baseline, 2, 4 and 8wk respectively, with a significant difference among them (F=5.208, P<0.05).When the cumulative dose reached to 700mg and 1400mg, no one had methazolamide-related complications;and when it came to 2800mg, 5 patients (33%) had methazolamide-related complication.After the withdrawal of methazolamide 1wk, 1 and 3mo, 3 patients (20%), 5 patients (33%) and 8 patients (53%) relapsed, respectively.CONCLUSION: Methazolamide is beneficial in improving macular edema and vision in 4wk.When the cumulative dose is more than 1400mg, we need pay attention to the complications.After discontinuing methazolamide for 1wk, macular edema relapsed in some patients, and more than half of patients recurred after 3mo.So the patients should be followed closely in 3mo after withdrawal of methazolamide.

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.

To prepare salvianolic acid phospholipid compound. With the compound of salvianolic acids and soybean phospholipid as the index, mono-factor experiment and orthogonal design experiment were conducted to screen its technical parameters. According to the results, the optimal preparation conditions of salvianolic acid phospholipid compound were that THF were taken as the reaction solvent, the concentration time was 3 h, the reactant concentration was 5 g x L(-1), the mass ratio of salvianolic acids and phospholipid was 1: 1.5, and the reaction temperature was 40 degrees C. The oil/water partition coefficient of the prepared salvianolic acid phospholipid compound significant increased in water and buffers with different pH values. The results of phase analysis such as DSC, XRD and FTIR indicated that salvianolic acids existed in phospholipid in an amorphous state.

Objective To study the causes of reoperation after biliary duct operation, in order to decreasing the rate of biliary tract reoperation. Methods The clinical data of 828 patients who underwent reoperation of biliary duct diseases in Nankai hospital between 1990-1999 were evalated, and the causes of biliary duct reoperation were classified and analysed.Results The most common cause for reoperation was recurrent or retained bile stone(65.10% ), bile stone companied by stenosis of the sphincter of oddi (33.82%), simple stenosis of sphincter of Oddi ( 9.54%), traumatic stricture of bile duct and stricture of bilioenteric anastomosis( 10.39%), bile duct obstruction due to tumor (6.52%), and other less important factors. Conclusions Recurrent or retained bile duct stone was the main cause for biliary reoperation,and stenosis of the sphincter of Oddi was the next important factor for reoperations.Thoroughness of the initial operation and rationality of operative procedure are the chief factors to decrease bile duct reoperations.
