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.

Objective To investigate the role of serum in children with Kawasaki disease(KD)in acute stage and ?-globulin role in monocyte cell-produced leukotriene B4(LTB4).Meanwhile,to investigate the effects of the monocyte cell conditioned media(MCM)on the expression of leukotriene B4 receptor 2(BLT2)in endothelial.In order to understand whether LTB4-BLT2 pathway gets involved in vascular damage in KD and the mechanism of ?-globulin in the lessening vascular damage of KD.Methods The concentration of LTB4 in cell culture after the stimulation by serum of healthy children,serum of acute KD and serum of acute KD with ?-globulin were observed,respectively.The expression of BLT2 in the endothelial was determined by flow cytometry.Results 1.The serum of children with KD increased the concentration of LTB4 in MCM(P

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 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.

Objective: To establish a female SPF BALB/c mouse model of antibiotic-associated intestinal microflora disturbance and analyze the effect of lactobacillus acidophilus.Methods: Female SPF BALB/c mice were treated with ceftriaxone in drinking water for five days,and followed by oral gavage of sodium chloride as natural recovery group or lactobacillus acidophilus(108CFU/mL) as therapeutic group.After seven days the intestinal microflora of the cecum content was abstracted and computed by plate counts and 16S rDNA-based PCR-DGGE method.Results: Plate counts indicated that the number of original bacterium lacticum and bacillus bifidus decreased significantly and enterococci proliferated abnormally after antibiotic treatment.After lactobacillus acidophilus treatment,the number of physiological bacteria and enterococci go back to normal levels.DGGE profile clearly indicated that the dominant bacteria changed and the bacterial diversity of intestinal microbiota was obviously decreased in the antibiotics treated group. Conclusion: Oral gavage of lactobacillus acidophilus has adjustment effect on Ceftriaxone induced intestinal microbiota disturbance.PCR-DGGE is a rapid、effective molecule method to reveal the whole microbiota status.

Objective To approach the method for improving the intellectual development,of whom had suffered from parity′s brain damage.Methods The patients were divided into 2 groups randomly(age range from 7 days to 18 months) who were observed and compared for 3 years.Group A was bundle of intervention which had been under early intervention program since infant.Group B was bundle of comparing of which had not been under early intervention.Results Observed for 6 months and 12 months,the intellectual development of group A was prior to that of group B(age 6 months P

Objective To further understand the cellular events of myocarditis,we have examined the myocardial mitochondria structure and activity of ATPase in mice with myocarditis,and observe the interventional effect of different doses of carptopril.Methods Sixty male Balb/c mice were randomly divided into 5 groups:infected coxsackie B3 virus(CVB3)group,infected CVB3 and treated with carptopril(in a dose of 10,30,or 100 mg/kg,twice a day)groups and control group.Captopril was administered after infection.The activity of Na+-K+-adenosine triphosphatase(Na+-K+-ATPase)and Ca2+-adenosine triphosphatase(Ca2+-ATPase)of myocardial mitochondrial as well as the morphological of myocardial mitochondrial were investigated on day 14.Results The activity of mitochondrial Na+-K+-ATPase and Ca2+-ATPase were significantly higher(Pa0.05).Conclusions The favorable effects of captopril exerts on myocyte mitochondria were shown in a dose-dependent manner.Thirty and 100 mg/kg,twice a day captopril protecs the membrane integrity and thus plays a role at the recovery of depressed mitochondrial Na+-K+-ATPase and Ca2+-ATPase activity and also in myocytes injury.
