BACKGROUND:Open reduction and internal fixation cause big trauma and many complications. With the progression of minimal y invasive concept, percutaneous pedicle screw fixation gradual y showed its obvious superiority. ＜br> OBJECTIVE:To compare clinical outcomes of minimal y invasive percutaneous pedicle screw fixation versus open surgery in the treatment of thoracolumbar fracture. ＜br> METHODS:From October 2012 to January 2014, 50 cases of thoracolumbar fractures, including 25 cases in the minimal y invasive percutaneous pedicle screw fixation group and 25 cases in the open surgery group, were retrospectively analyzed. The differences in length of skin incision, intraoperative blood loss, operation time, postoperation hospital stay, and visual analog scale scores were compared. Serum creatine kinase activity and C-reactive protein levels were measured before surgery and at 24 and 48 hours after operation. Imaging results were used to observe vertebral height and kyphosis Cobb’s angle changes. ＜br> RESULTS AND CONCLUSION:Compared with the open surgery group, the length of skin incision was smal er and intraoperative blood loss was less, operation time, bed time and hospital stay were shorter, and pain of the wound was lighter in the minimal y invasive group. No significant difference was found in serum creatine kinase activity and C-reactive protein levels between the two groups. Serum creatine kinase activity and C-reactive protein levels were higher at 24 and 48 hours after treatment compared with before treatment in both groups. Serum creatine kinase activity and C-reactive protein levels were higher in the open surgery group than in the minimal y invasive group at 24 and 48 hours. There were significant differences in vertebral height and kyphosis Cobb’s angle in both groups after treatment compared with before treatment (P＜0.01). No significant difference in vertebral height and kyphosis Cobb’s angle was detected between the two groups after treatment (P>0.05). Results indicated that minimal y invasive percutaneous pedicle screw fixation and open surgery in repair of thoracolumbar fractures had similar outcomes. However, the trauma of minimal y invasive percutaneous pedicle screw fixation was apparently less than open surgery.

OBJECTIVETo evaluate the role of serum level of procalcitonin (PCT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood cell count (WBC) as predictors in postoperative early infectious complications with fever after posterior lumbar internal fixation (PLIF).

METHODSA retrospective study was conducted from January 2012 to January 2014. Fifty-two patients with fever in the early stage(within 10 days) after the PLIF were collected in the study. They were divided into infection group and non-infection group (group A and group B) according to the results of postoperative blood culture. There were 26 patients in group A and 32 patients in group B. The values of PCT, CRP, ESR, and WBC count were compared and analyzed between two groups.

RESULTSThe values of PCT, CRP, and ESR in group A were higher than those of group B. Meanwhile, CRP and ESR in group B were still higher than the normal range. Among the 26 patients with infections (group A), PCT was superior to CRP and ESR, had a good ability in discriminating different kinds of postoperative infections. The area under the ROC curve of serum PCT levels was the largest (CI 95% was 0.81 to 0.98) in the indexs; and ROC curve of WBC count was no statistically significant. When the cut off points of each predictors were evaluated, the higher sensitive was CRP and reached at 90.27% and the higher specific was ESR and reached at 88.50%.

CONCLUSIONFor the patients with fever at the early stage after the PLIF should be paid attention and reasonable choosing predictors are helpful to identify postoperative infection in the early stage. The CRP and ESR may be influenced by the surgery, and the PCT level is helpful to differentiate infection type.

Objective To assess the safety and efficacy of domestic sirolimus-eluting stent(SES)compared with bare metal stent(BMS)in the primary percutaneous coronary intervention(PCI)for patients with ST-segment elevation AMI in a real-world scenario.Method From January 2005 to March 2006,a total of 143 patient with ST-segment elevation AMI were enrolled in this study,and all of them underwent primary percutaneous coronary intervention(PCI).Among the 143 patients,74 were treated with domestic SESs(Firebird stent)and 69 with BMSs.The incidence of major adverse cardiovascular events(MACE:death,reinfarction,and target vessel revascularization[TVR])was evaluated at 30 days and 180 days.Continuous variables were compared using Student's unpaired t test.Categorical variables were compared using Fisher's test.Cox proportional hazard survival models were used to assess risk reduction of adverse events.P value

Aim To investigate the effect of PLK1 on epithelial-mesenchymal transition (EMT)of human e-sophageal squamous cell carcinoma (ESCC)cells TE-1 5 and its relevant molecular mechanisms.Methods PLK1 overexpressed ESCC cells and control vector were used as the experimental cells.The expression of EMT-related protein markers E-cadherin and vimentin were measured by Western blot.vimentin mRNA was measured by Real-time PCR.Total cellular protein and nuclear protein were respectively extracted,and then they were used to detect the expression of β-catenin by Western blot.β-catenin siRNA and non-specific siR-NA were transiently transfected into the cell clones overexpressed PLK1 ,and then vimentin was detected by Western blot.β-catenin protein degradation com-plex was detected by immunoprecipitation and Western blot.Results The mesenchymal marker vimentin was distinctively upregulated and the epithelial marker E-cadherin was distinctively downregulated in the cell clones overexpressed PLK1 ,compared with those in the vector clones.This indicated that EMT occurred in ESCC cells.vimentin mRNA was also markedly in-creased.In the cell clones overexpressed PLK1 ,β-catenin were both elevated from the total cells and the nucleus.The expression of vimentin was reduced whenβ-catenin was knocked down.APC and GSK-3βwere both reduced from Axin immunoprecipitate in the cell clones overexpressed PLK1 .Conclusion PLK1 up-regulates vimentin and promotes EMT in ESCC cells probably by inhibiting the formation of protein degrada-tion complex and stabilizing β-catenin.
