Objective To detect the effects and mechanisms of CD147 in thyroid cancer cell SW579. Methods RT-PCR and Western-blot were used to determine the levels of CD147 mRNA and protein in SW579 cells after treated with CD147 specific small interference RNA (siRNA). The proliferative ratio of SW579 cells after treated with CD147 siRNA was detected by CCK-8 assay. We detected the changes of cellular mobility after treated with CD147 siRNA by transwell assay. Mobility related proteins were analyzed by western-blot. Results The proliferative ratio and the mobility of SW579 cells were inhibited significantly by down-regulation of CD147. The levels of MMP-2 and MMP-9 were lower in treated cells than untreated ones. Expression of Wave 2 and a mobility related protein were decreased in accompany with down-regulation of CD147. Conclusion Down-regulation of CD147 inhibits mobility of SW579 by suppressing MMP-2, MMP-9 and WAVE 2.

Objective To explore the effects of single rectangle cage interbody fusion combined with pedicle screw fixa?tion for isthmic spondylolisthesis. Methods Data of the 34 cases with isthmic spondylolisthesis hospitalized at our department from March 2012 to February 2015 were retrospectively analyzed. All cases were operated by posterior pedicle screw fixation com?bined with single rectangle cage interbody fusion. There were 21 males and 13 females, aging from 18 to 63 years old (with an aver?age age of 41.6±8.2 years). Lesion segments were L4 in 15 cases and L5 in 19 cases;there were 12 cases in Meyerding I degree, 16 in II degree and 6 in III degree;28 patients had lower back pain associated with lower limb pain;19 patients had lower back pain associated with numbness of lower limb;18 patients had lower back pain associated with lower limb muscle weakness and 2 pa?tients had urination and defecation function disturbance. The surgical operation time, bleeding, postoperative drainage flow, graft fusion rate, complications were measured, and the intervertebral disc height, Japanese Orthopaedic Association (JOA), Oswestry disability indes (ODI), visual analogue scale (VAS) score were compared before and after treatment. Results The operation of 34 patients was successfully completed with the average operation time of 1.8 ± 0.8 h, and the bleeding in operation was 362.4 ± 93.7 ml, while postoperative drainage flow was 116.3±54.2 ml. All patients were effectively followed up for 12 months to 46 months (av?erage, one year and 10 months). Two weeks after operation, the intervertebral disc height were obviously increased (9.85±1.11 mm, 9.63 ± 1.04 mm), and there were significant difference compared with preoperative results (6.53 ± 0.98 mm, 6.24 ± 1.07 mm), but there were no significant difference compared with the latest follow?up results (9.23±1.33 mm, 9.30±1.16 mm). At the latest follow?up, JOA score was 13.19±1.08, ODI score 12.34±7.52, VAS score 2.23±1.51, and there were significantly different in each score compared with preoperative results. The symptoms of low back pain, lower limb nerve dysfunction and quality of life were signifi?cantly improved compared with preoperative situation. At the 16 month follow?up, all postoperative patients with vertebral body bone graft were judged to be fused. There was no pedicle screw loosening, fracture and so on. Conclusion Single rectangle cage interbody fusion combined with pedicle screw fixation for the treatment of isthmic spondylolisthesis is a kind of mini?invasive, less bleeding, safe and effective surgical method.

Objective To study clinical application and complication of heavy silicon oil (Densiron68) in the treatment of traumat- ic proliferative vitreoretinopathy.Design Non-comparatives,retrospective case series.Participants Twenty patients with proliferative vitreoretinopathy resulting from ocular trauma were recruited,whose retinal detachment arising from inferior or posterior retinal breaks. Methods Heavy silicon oil was applied to patients during vitrectomy.Silicone oil or gas was applied to patients with redetachment after heavy silicon oil was removed.Main Outcome Measures The rate of retinal attachment,vision,intraocular pressure,inflammatory re- action of anterior segment and silicone oil emulsification period.Results The rate of retinal attachment with one operation using heavy silicon oil was 50%(10/20 eyes)and 15%(3/20 eyes)with further surgery.The average follow-up time was 3.90?1.41 months.At the end of the follow-up,all tamponade agents were removed in 50% patients.Patients' logMAR vision after the surgery was 2.19?0.86,which was better than before the surgery (2.63?1.00) (P=0.037).There was little evidence of high intraocular pressure,excessive inflammatory reaction of anterior segment and cornea endothelial cell damage,but cataract became more serious without exception.Emulsification rate was 100% and the average emulsification period was 2.18?0.87 months.Conclusions Heavy silicon oil tamponade in vitreoretinal surgery for traumatic proliferative vitreoretinopathy has good efficacy and relatively few complications.However,its emulsification period is relatively short,which may constraint its application to a certain extent.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

Objective To assess the analytical performance of hs-cTnT and biological variations in healthy population as well as establish hs-cTnT reference intervals. Methods The serum samples from 100 acute myocardial infraction patients and 474 apparently healthy subjects were collected. The functional sensitivity,within- and between-run imprecision were determined. The hs-cTnT assay and con-cTnT assay were evaluated. The serum hs-cTnT levels were detected in apparently healthy subjects to establish reference intervals. Moreover,the long-term and short-term biological variations for hs-cTnT in healthy volunteers were assessed. Results The functional sensitivity of hs-cTnT was 0. 005 μg/L. The within- and between-run precision for lower level control(0. 014 μg/L) and higher level control(2. 500 μg/L) was 2. 97% vs 3. 64%and 0. 66% vs 1.01% ,respectively. The correlation between hs-cTnT assay and con-cTnT assay was good ( R2 =0. 972 ,P ＜0. 01 ). The 99th percentile in apparently healthy subjects was 0. 003 μg/L for women less than60 years, 0.008 μg/L for men less than 60 years, 0.015 μg/L for women above 60 years and 0. 021 μg/L for men above 60 years. The CVa, CVi, CVg and CVt of short-term biological variations in detecting hs-cTnT from 22 apparently healthy subjects were 3.8%, 4. 8%, 49.9% and 58.5%,respectively. The CVa,CVi ,CVg and CVt of long-term biological variations were 5. 3% ,6. 4% ,56. 6% and 68. 3% respectively. Conclusions The analytical performance of the hs-cTnT is better than con-cTnT assay,achieving acceptable level according to guideline. Our experimental result could provide the basis for the new high sensitivity cTnT assay in the diagnosis of acute myocardial infarction.

Objective To study the expression and function relations of the p63 in ovarian serous carcinoma,and compare them with normal ovary tissue.Methods RT-PCR,in situ hybridization and im- munohistochemistry were used to detect the expression of the p63 in ovarian serous carcinoma,ovarian bor- derline serous tumors,ovarian benign serous tumors and normal ovary tissues.Results All samples ex- pressed p63 mRNA through RT-PCR and immunohistochemistry,while the levels of expression in ovarian tu- mors was higher than that of normal ovary.p63 in human borderline and malignant ovarian tumors was higher than that in human benign ovarian tumors with significant difference,which suggested p63 may play great roles in the origin and progression of ovarian tumors.The result of in situ hybridization showed that positive expression rate of p63 mRNA in ovarian cancer (92.1%) was significantly higher than that in normal ovary(0) or LWP ovarian cancer(50.0%).Conclusion Expression of p63 plays an important role in the development of varian carcinoma,and along with the difference of histological stage and clinico-pathological stage,the ex- pression of p63 gene and protein level were different.
