OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.
METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.
RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.
CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.

Objective To investigate whether porcine endothelial cells transfected with SP1 de-coy ODNs could resist complement-mediated cytotoxicity during the model of SV-40-PED with human serum in vitro. Methods Immortalized porcine aortic endothelial cells of the line PED were divided in-to three groups. The transfected group was SV-40-PED with SP1 decoy ODNs. The mismatched group was SV-40-PED with scrambled SP1 decoy ODNs. The negative group was cells with oligo-fectamine only. The expression of α1,3-GT mRNA and αGal was detected after 26 h by using fluores-cence microscope, Western blot, RT-PCR and lactate dehydrogenase (LDH) activity assay. Results Fluorescence microscopy observed the decreased fluorescence of αGal after SP1 decoy ODNs transfec-tion. Dotted fluorescent decrease could be observed on some membrane while the mismatched group and negative group with bright green fluorescence. Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was decreased to 52.6% of the negative group (P<0.05). The expression of α1,3-GT mRNA in the PED cells transfected with decoy ODNs was 0.42±0.20 (isoform 1) and 0.27±0.12 (isoform 2) respectively, significantly lower than in the negative group (isoform 1, 0.72±0.17; isoform 2, 0.50±0.19; both P<0.05). The expression of α1, 3-G Tin the mismatch group was not different from that in the negative group (P>0.05). 20% normal hu-man serum (NHS) and 40 % NHS had cytotoxic effect on both mismatch and negative groups, but de-coy ODNs could confer SV-40-PED protection from the cytolysis effect (P<0.05), which made a re-markable reduction of complement-mediated cytotoxicity towards SV-40--PED. Conclusions SP1 decoy ODNs could confer porcine endothelial cells protection from complement-mediated cytotoxicity effect in vitro.

Objective To establish an ultraviolet-irradiation damage model in cultured fibroblasts derived from human skin and to explore the potential protective effects and mechanisms of amyloid precursor protein 17-met peptide (APP17-mer peptide) on the oxidative damage and collagen metabolism in cultured fibroblasts after ultraviolet irradiation. Methods Human dermal fibroblast cultures were established by outgrowth from foreskin biopsies of a healthy donor and were irradiated by a single exposure to ultraviolet rays and cultured in a series of concentrations of APP17-mer peptide (0, 20, 40, 80 μmol/L).The activity of fibroblasts was detected by the assay of MTT. The intracellular ROS level was measured with a confocal microscope. The expression of MMP-1 mRNA was analyzed real-time quantitatively following RT-PCR. Results Primary cultures of human skin fibroblasts were established from human foreskin in DMEM supplemented with 10 % fetal bovine serum. UV irradiation depressed cellular activity and increased intracellular level of ROS (P<0.05). 40μmol/L and 80μmol/L APP17-mer peptide increased the cellular activity in both UV irradiated fibroblasts and unirradiated fibroblasts (P<0.05), however,20 μmol/L did not show such protective effects (P>0. 05). 40μmol/L APP17-mer peptide could depress the level of ROS in irradiated libroblasts. A single exposure of fibroblasts to UV irradiation resulted in 1.78 foldup-regulation of MMP-1 mRNA compared with unirradiated sample, 40μmol/L and 80μmol/L APP17-mer peptide decreased the expression of MMP-1 mRNA (P<0.05 and P<0.01, respectively).Conclusion APP17-mer peptide can enhance cellular activity under UV-induced oxidative stress and in-hibit collagen degradation in fibroblasts irradiated with ultraviolet rays. Inhibition of ROS production may be involved in the protective mechanism of APP17 peptide.
10.Vascular-specific promoters and cis-regulatory elements.
Chinese Journal of Biotechnology 2003;19(2):131-135
Vascular-resided bacterial and fungal diseases have caused a great deal of yield loss and quality reduction in crop production world-wide. For genetic engineering of crops resistant to these diseases, it is disirable to have a strong and vascular-specific promoter. This article reviews the progress in identification of vascular-specific promoters and its function. To date, roughly twenty vascular-specific promoters have been documented. The cis-elements and motifs have been studied in detail for the promoters of bean phenylalanine ammonia lyase (PAL2), bean glycine-rich protein (grp 1.8) and Arabidopsis profilin2 (pfn2) in particular.The motif of vs-1 (CATGCTCCGTTGGATGTGGAAGACAGCA) found in grp 1.8 promoter was a cis-element that specificically bind to a transcription activation factor VSF-1 protein (one of the bZIP proteins). Mutation of vs-1 prevented it from binding to VSF-1 that resulted in abolishing the vascular-specific expresson of gus gene. Motifs of AC-I and AC-II found in PAL2 promoter were also found to be essential for vascular-specific expression. In our laboratory we have dissected pfn2 promoter into three domains (A, B, C) through 5'-deletion analysis. In this promoter we have identified two core sequences of ACGT that is commonly found in the binding sites of bZIP protein, the most abundent transcription factor existed in plants. In additon, the pfn2 promoter also contains an AC- I like sequence (CCACCTAC) that is similar to the AC- I motif (CCCACCTACC) found in PAL2 promoter. These promoters and cis-elements may have a wide range of potential applications to the genetic improvement of crops resistant to vascular diseases.
