OBJECTIVETo observe the therapeutic effect of Bushen Qiangdu Recipe (BSQDR) on osteoporosis and bone loss in patients with ankylosing spondylitis (AS).

METHODSPatients with AS were randomly assigned to two groups. The 288 patients in the treatment group received BSQDR (consisting of cibotii rhizoma, antler, prepared rehmannia root, epimedium herb, rhizoma drynariae, teasel root, eucommia bark, pangolin scales, etc., one dose daily, taken in two portions, once in the morning and once in the evening). The 72 patients in the control group received SIDSM and sulfasalazine. The therapeutic course for both was six months. Clinical symptoms, pillow distance from the wall, hand distance from the ground, jaw distance from the handle, chest mobility, Schober test, spinal mobility and other signs of disease activity indices (ESR and CRP) were observed in patients before and after treatment. The bone mineral density (BMD) testing was performed in the lumbar spine, the femur, the forearm, and the heels, etc. Osteocalcin (BGP), calcitonin, parathyroid hormone (PTH), etc. bone metabolic indices were detected.

RESULTSBASFI, BASDAI, the overall assessment, the spinal pain, pillow distance from the wall, hand distance from the ground, jaw distance from the handle, chest mobility, Schober test, spinal mobility, and so on were all improved to some extent when compared with before treatment in the treatment group (P<0.05). The ESR and CRP decreased to various degrees, showing statistical significance when compared with before treatment (P <0.01). BGP increased and PTH decreased, showing statistical difference when compared with before treatment (P<0.05). The BMD in patients' lumbar spine, femoral neck, Ward's triangle, femoral trochanter increased to various degrees. The calcaneal intensity index, blood uric acid (BUA) and SOS values also increased more than before treatment, showing statistical significance (P<0.05). Long-term oral administration of BSQDR was safe, with no obvious adverse reaction.

CONCLUSIONSBSQDR showed significant effect in treatment of AS. It could regulate the bone metabolic level in patients, attenuate the immune inflammatory response, improve the spine and joint activities functions, increase bone formation, reduce bone resorption, thereby, enhancing the BMD, showing significant therapeutic effect on osteoporosis in AS patients.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.

Objective To investigate the regulatory effects of cyclic diguanylate (c-di-GMP) signaling on CheB and CheR, which were chemotaxis regulatory proteins relating to the motility of Leptospira interrogans.Methods Real-time PCR was used to determine the expression of cheB1, cheB2, cheB3, cheR1 and cheR2 genes at mRNA level during Leptospira interrogans infection.Fragments of these genes were amplified and cloned into the expression vector pET-28a, respectively, to construct the prokaryotic expression system for them.Colony morphologies of Escherichia coli (E.coli) strains that overexpressed the target genes were observed to determine the regulatory effects of c-di-GMP on CheB and CheR.Results The expression of cheB1 gene at mRNA level increased 60 min after infection and reached the peak at 90 min.Compared with the control group, the expression of cheB3 gene at mRNA level were up-regulated, while no significant difference in the expression of cheB2 and cheR genes was observed 60 min after infection.The prokaryotic expression system for the five genes was successfully constructed and the purified proteins were obtained.CheB1, CheB3 and CheR2 improved the motility of E.coli, but that was inhibited by the inhibitor of diguanylate cyclase (DGC) or phosphodiesterase (PDE).Conclusion CheB and CheR regulate the swarming motility of E.coli and are affected by intracellular c-di-GMP.
