Objective: To investigate the effect of adhesion of Lactobacillus reuteri JCM1081 to enterocyte-like HT-29 cells on filamentous cytoskeleton.Methods:Cultured human intestinal enterocyte-like HT-29 cells were used.Cell permeability was examined in vitro by Evans blue labeled albumin and Examination of F-actin was conducted by direct immuno-fluorescence labeling using fluorescein labeled phalloidin.Results:Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection.The distribution of F-actin were also not altered.Conclusion :Lactobacillus reuteri JCM1081 exerts a protective effect against the filamentous cytoskeleton rearrangement and permeability lesions promoted by enteropathogenic Escherichia coli infection.

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

To establish a convenient and rapid method for identification of Pseudostellariae Radix by molecular identification, the rDNA-ITS sequences of Pseudostella riaheterophylla and its adulterants had been aligned to find out specific fragment. The specific primers against the fragment were designed and the PCR amplification conditions were optimized. The fluorescence reaction of the PCR products colored by 100 x SYBR Green I was observed under UV. The concentration of reaction buffer included 5.5 μL DNA Taq polymerase premix, 10 pmol Tzs-2F and 10 pmol Tzs-2R, 20-80 ng template DNA, and plus double sterile distilled water to 25 μL. The PCR thermal profile was as follows: predenaturation at 95 degrees C for 1 min, followed by 30 cycles of denaturation at 95 degrees C for 5 seconds, primer annealing and extension at 56 degrees C for 15 seconds, then it was extension at 72 degrees C for 30 seconds. The fluorescence reaction of Pseudostellariae Radix showed green fluorescence, while adulterants had not. Extraction, amplification DNA and all steps of molecular identification could be completed successfully in 40 minutes. The approach could amplify DNA template of Pseudostellariae Radix specificity, and its product with 1 μL 100 x SYBR Green I could engender green fluorescence under UV. The method was simple and accurate, so it could be used for identification of Chinese traditional medicine.

Objective To evaluate the effect of Alprostsdil combined with Magnesium Isoglycyrrhizinate on hepatocirrhosis at active phase. Method 74 inpatients collected from our hospital were randomly divided into control group(37 cases)and treatment group(37 cases). The patients in control group were given conventional liver protecting treatment. In addition to routine therapy of the control group, the patients in treatment group received intravenous Alprostadil and Magnesium Isoglycyrrhizinate injection once a day for 4 weeks. Results The total effective rate of treatment group was 67. 6%, and that of control group was 40. 5%, and the difference was significant (P < 0. 05).Conclusion Alprostadil combined with Magnesium Isoglycyrrhizinate has good clinical therapeutic effect on hepatocirrhosis at active phase.

Objectives To report the clinical and myopathological features in a case with Danon disease caused by a novel mutation in the lysosome-associated membrane protein-2 ( LAMP2 ) B gene.Methods A 16-year-old boy presenting progressive muscle weakness and atrophy, accompanied with spinal ankylosis was clinically evaluated including electrocardiogram, echocardiogram and electromyogram.Muscle biopsy was carried out in the patient.The histological staining, ultrastructural examination, and immunohistochemical staining with antibodies against dystrophin, merosin and C5b9 were performed in frozen sections.LAMP2B sequence was analyzed in the patient and his parents.Results Electrocardiogram in the patient showed Ⅰ atrioventricular block; echocardiogram revealed focal hypertrophy in mitral valve with mild cardiac diastolic dysfunction; electromyogram indicated myogenic and neurogenic patterns.Muscle pathology study revealed numerous vacuoles located at the fibers.Dystrophin, merosin and C5b9 was immuno-positive around the vacuoles.Electron microscopy revealed vacuoles surrounded by sarcolemma and abnormal lysosome aggregating at the fibers.A novel nonsense mutation ( K402X ) in the LAMP2B gene has been identified in the patient but not in his mother and 50 normal controls.Conclusions Danon disease caused by K402X mutation in C-terminus of LAMP2B presented benign course of the disease characterized by prominent vacuolar skeletal myopathy, mild cardiac abnormalities and peripheral neuropathy.

Objective To report filaminopathy with novel insertion mutation in a Chinese family.Methods Total 19 patients from successive 5 generations involved in an autosomal dominant family. The detailed clinical manifestations had been described (Chinese Journal of Neurology, 2008, 41:751-755).The filamin C gene sequencing was performed in 3 patients, 5 family members without symptoms and 50 normal persons. The amplified fragments of the exon 18 in filamin C gene were cloned into pBluesripts vectors, then sequenced and identified with capillary electrophoresis. Results 18-nucleotide deletion and 6-nucleotide insertion were identified in the exon 18 of filamin C gene. The mutation caused the disturbance of the seventh immunoglobulin-like domain in filamin C, leading to the instability of dimmers of filamin C.Another 2 patients in the family had same mutation while 5 family members without symptoms and 50 normal controls were normal. Conclusion The novel nucleotide deletion-insertion in exon 18 of filamin C gene causes filaminopathy. This disease can appear in non-Nordic race.
