2.The synergistic antitumor effects of berberine alpha-hydroxy-beta-decanoylethyl sulfonate with hydroxycamptothecine and its effect on topoisomerase.
Acta Pharmaceutica Sinica 2011;46(4):390-4
Synergistic antitumor effects of HB (berberine alpha-hydroxy-beta-decanoylethyl sulfonate, houttuyn berberine) with HCPT (hydroxycamptothecine), and its correlative mechanism were studied in vitro. MTT assay was employed to determine the cytotoxicity of HB combined with HCPT in tumor cells culture in vitro, IC50 and combination index (CI value) were used to evaluate the synergistic effects. The supercoiled DNA relaxation mediated by topoisomerase I & II was measured by agarose gel electrophoresis assay, and influence of HB was detected. The results showed that HB could inhibit the proliferation of tumor cells (SGC-7901, SW1116 and SW480) in vitro, and the inhibition ratio was increased, IC50 was reduced when combining with HCPT. CI value of the two drugs was less than 1 in HepG2, SW480, SGC-7901 and SW1116 cells. The lowest value was 0.447, 0.626, 0.161 and 0.178 in these tumor cells, respectively, further indicating HB has synergistic action with HCPT on suppressing tumor proliferation. The agarose gel electrophoresis assay showed HB can inhibit topoisomerase I & II activity of SW480 cells at the concentration of 2.0-8.0 mg x L(-1). HCPT is a typical inhibitor of topoisomerase I , the synergistic action between HCPT and HB on suppressing tumor proliferation is perhaps related to the congenerous inhibition of topoisomerase.
3.Bone morphogenetic protein-2 gene affects the histology and collagen type Ⅰ andⅡ expressions in degenerative intervertebral disc
Chinese Journal of Tissue Engineering Research 2013;(43):7501-7506
BACKGROUND:Studies have shown that the changes of extracellular matrix in degenerative intervertebral disc tissues mainly present as the decrease of col agen type Ⅱ and proteoglycan contents and the increase of col agen type Ⅰ content. OBJECTIVE:To explore the effect of adeno-associated virus-mediated bone morphogenetic protein 2 gene on nucleus pulposus Ⅰ and Ⅱ col agen levels in rabbit degenerative intervertebral disc tissues. METHODS:L 2-3 , L 3-4 , L 4-5 and L 5-6 lumbar discs of 12 New Zealand white rabbits were punctured to establish interverbral disc degeneration model. Subsequently, 12 rabbits were randomly divided into three groups, four rabbits in each group. The intervertebral discs in the adeno-associated virus-mediated bone morphogenetic protein 2 group were injected with the adeno-associated virus-mediated bone morphogenetic protein 2 gene, the intervertebral discs in the adeno-associated virus group were injected with adeno-associated virus only, while the discs in the normal saline group were injected with normal saline. Al rabbits were sacrificed after injected for 8 weeks, and the L 2-3 , L 3-4 , L 4-5 and L 5-6 lumbar discs of each rabbit were col ected, paraffin-embedded and sliced. The histological changes of nucleus pulposus were observed with hematoxylin-eosin staining, and the immunohistochemistry was used to detect the col agen type Ⅰ and Ⅱ expressions in nucleus pulposus. Semi-quantitative analysis was performed. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that the nucleus pulposus in the intervertebral disc tissues was less in the adeno-associated virus-mediated bone morphogenetic protein 2 group, the nucleus pulposus was in single or clustered distribution with clear nucleus structure and without fibrous tissue fil ing. The tissue structures of nucleus pulposus were the same in the adeno-associated virus group and normal saline group, the cellnumber in nucleus pulposus was smal , the nucleus pulposus was shrunken and shriveled, and the cells were fil ed with fibrous tissue and arranged disorderly. Immunohistochemistry staining showed the expression of col age type Ⅰ in the intervertebral disc nucleus pulposus of adeno-associated virus-mediated bone morphogenetic protein 2 group was higher than that of the adeno-associated virus group and normal saline group (P<0.05);the expression of col age typeⅠ in the intervertebral disc nucleus pulposus of adeno-associated virus-mediated bone morphogenetic protein 2 group was lower than that of the adeno-associated virus group and normal saline group (P<0.05). The results indicate that adeno-associated virus-mediated bone morphogenetic protein 2 can inhibit the expression of col agen type Ⅰ in the intervertebral disc nucleus pulposus, promote the expression of col agen type Ⅱ. Maintaining the content of col agen in intervertebral disc can keep the histological structure and morphology of intervertebral disc, stabilize the environment for nucleus pulposus cellgrowth, and delay the intervertebral disc degeneration.
7.Combined application of helicobacter pylori stool antigen test and serology in epidemiologic study of helicobacter pylori infection in children
Journal of Applied Clinical Pediatrics 2004;0(11):-
Objective To evaluate the feasibility of combined application of helicobacter pylori stool antigen(HpSA)-and traditional serology in epidemiologic study of helicobacter pylori(Hp) infection in children. Methods Hp serum IgG antibodies were examined among 480 healthy children. Heticobacter pylori stool antigen(HpSA) were measured among children who were seropositive. Hp status was defined as positive when stool antigen test was positive, Hp status was defined as negative when seronegative. A case - control study was conducted to identify risk factors of Hp infection in preschool children. Results Among 480 preschool children, 172 (35 8 %) were sero- positive, 64(13.3 %) with positive result of HpSA test were diagnosed as current Hp infection. Univariate factor analysis demonstrated that Hp infection clustered in families and Hp infection was often acquired in childhood by oral-oral and fecal - oral person to person transmission. Conclusions HpSA and serology screening are two nomnvasive tests, simple not costly, effective and accurate. The combination of these 2 noninvasive methods can be applied in epidemiologic study of Hp infection in childrenJAppl Clin Pediatr,2004,19(11):948-950

BACKGROUND: Current treatmemt strategy cannot efficiently relieve or reverse the disk degeneration, and neither surgical treatment nor nonsurgical treatment has gained satisfactory long-term effect. Therefore, more and more researches have focused on the cell therapy. OBJECTIVE: To explore the present states and application prospect of cell therapy, especially stem cells for degenerative intervertebral disc repair.METHODS: A computer-based search for related articles in PubMed database published between January 2011 and January 2016 using the English keywords of stem cell, intervertebral disk degeneration. Literatures addressing cell therapy for degenerative intervertebral disc repair were selected, and the articles published lately or original researches in authoritative journals were preferred.RESULTS AND CONCLUSION: A total of 205 articles were selected firstly, and 50 eligible articles were enrolled finally in accordance with the inclusion criteria. The mixtures of stem cells and carrier are injected into the degenerative intervertebral disk, to repair or displace abnormal cells. This strategy has been accepted by many researchers, and considered as a promising treatment. However, there is little evidence about the safety of clinical treatment with cell therapy, which still needs to be explored in depth.
