BACKGROUND:There are stil about 10%-30%of patients presenting no obvious improvement of symptoms after lumbar disc herniation surgery, which are col ectively known as the lumbar spine post-surgery failure syndrome, and lumbar instability is one of the important reasons. OBJECTIVE:To evaluate the feasibility and efficacy of surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation on lumbar intervertebral disc protrusion concurring lumbar instability via MAST Quadrant retractor. METHODS:From December 2011 to October 2012, 62 cases of lumbar intervertebral disc protrusion concurring lumbar instability were treated with posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor. There were 38 female and 24 male ranging in age from 37 to 69 years (average 53.7 years). After operation, al patients were fol owed-up to evaluate the effect of the treatment. RESULTS AND CONCLUSION:The operative time was 90-210 minutes, average 145 minutes, and the amount of blood loss was 50-300 mL, average 120 mL. The hospitalization time was 5-9 days, average 6 days. Al incisions healed by first intention. Al patients were fol owed up 7.2 months on average (from 3 to 10 months). The preoperative JOA score was (10.25±2.34) points. The postoperative JOA score decreased to (18.31±3.12) points at the fol ow-up after 1 month and (25.35±2.61) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). The preoperative VAS score was (8.24±1.15) points. The postoperative VAS score decreased to (2.97±1.12) points after 1 month and (1.13±0.39) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). According to reforming Macnab standard, the results were excel ent in 53 cases and good in 9 cases at the last fol ow-up. The surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor is a safe, effective and minimal y invasive surgical technique in treating lumbar intervertebral disc protrusion concurring lumbar instability.

To establish single- and double-transfected transgenic cells stably expressing hMATE1, hMATE1 cDNA was cloned by RT-PCR from human cryopreserved kidney tissue, and subcloned into pcDNA3.1(+) plasmid by virtue of both HindIII and Kpn I restriction enzyme sites. Subsequently, the recombined pcDNA3.1(+)- hMATE1 plasmid was transfected into MDCK, MDCK-hOCT1 or MDCK-hOCT2 cells using Lipofectamine 2000 Reagent. After a 14-day-cultivation with hygromycin B at the concentration of 400 µg · mL(-1), all clones were screened with DAPI and MPP+ as substrates to identify the best candidate. The mRNA content of hMATE1, the cellular accumulation of metformin with or without cimetidine as inhibitor, or transportation of cimetidine was further valuated. The results showed that all of the three cell models over expressed hMATE1 mRNA. The cellular accumulation of metformin in MDCK-hMATE1 was 17.6 folds of the control cell, which was significantly inhibited by 100 µmol · L(-1) cimetidine. The transcellular transport parameter net efflux ratios of cimetidine across MDCK-hOCT1/hMATE1 and MDCK-hOCT2/hMATE1 monolayer were 17.5 and 3.65, respectively. In conclusion, cell models with good hMATE1 function have been established successfully, which can be applied to study the drug transport or drug-drug interaction involving hMATE1 alone or together with hOCT1/2 in vitro.
