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 study the protective action of Semen Ziziphi Spiosaeand on acute myocardial ischemia and its effecte on infarcted area. Methods Left anterior descending(LAD) of coronary artery was ligated to cause the big rat's acute myocardial ischemia, and electrocardiogram (ECG) was used to appraise the effect of sour jujube kernel total soap on the myocardial infarcted area. Results Compared with control group, the experimental group treated with sour jujube kernel total soap glucosidal showed significantly smaller infarcted area; and ECG showed the heart rhythm, S-T piece and T wave value were significantly decreased in the experimental group. Conclusion Sour jujube kernel total soap glucosidal can reduce the myocardial infarcted area caused by ligature of LAD, so as to protect the cardiac muscle.

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 study the quality and transdermal properties of matrine microemulsion-based hydrogel (MBH) to provide basis for the development of the preparation.Methods: The stability of MBH was observed at 4 ℃ for 3 months and the changes of particle appearance, viscosity, pH and matrine content were observed.The transdermal permeation of MBH was investigated by a dual chamber permeation and diffusion device with excised mouse skin as the barrier.Taking rabbits as the experimental subjects, the irritation of MBH to the normal skin and damaged skin was investigated.Results: The appearance, viscosity, pH and matrine content of MBH at 4 ℃ in 3 months did not change significantly.In vitro transdermal test showed that MBH had a good penetration rate on mouse skin, and no skin irritation occurred after single or multiple administrations.Conclusion: MBH has good stability and high rate of transdermal penetration without skin irritation, which is a promising drug delivery system of matrine with good application prospects.
