BACKGROUND:It is stil controversial whether computer-assisted navigation elevated the accuracy and clinical outcomes of total knee arthroplasty.
OBJECTIVE:To analyze the literatures in English and Chinese on computer-assisted navigation total knee arthroplasty, and to evaluate the clinical outcomes between computer-assisted navigation and conventional total knee arthroplasty.
METHODWe retrieved PubMed, Ovid, Elsevier, China National Knowledge Infrastructure and Digital Library for literatures concerning randomized control ed trial of clinical outcomes of computer-assisted navigation and total knee arthroplasty published from January 1st 2005 to December 31st 2013. Meta analysis was performed with RevMan 5.0 software from the Cochrane col aboration. Clinical outcomes of computer-assisted navigation total knee arthroplasty and conventional technique were compared. The heterogeneity of data was checked.
RESULTS AND CONCLUSION:A total of 16 randomized control ed papers were included in this analysis. Computer-assisted navigation group consisted of 1 322 knees, and the conventional group consisted of 1 299 knees. Compared with the conventional group, patients in the computer-assisted navigation group had a significantly lower risk of implant malalignment at more than 3° as wel as more than 2°, malalignment for both coronal femoral component and coronal tibial component of>3°, and both sagittal femoral component alignment and tibial slope at>3° malalignment. The meta-analysis did not find a significant difference in the sagittal tibial component alignment, the rates of complications, axial (rotational) alignment of the femoral component and the tibial component between both groups. These data indicated that computer-assisted navigation group had significant improvement in alignment of the limb and the component position, but long-term clinical outcomes using computer-assisted surgery in total knee arthroplasty require further investigation.

BACKGROUND:Whether tranexamic acid can effectively and safely reduce blood loss and al ogeneic transfusion rate in total hip arthroplasty remains controversial at present. OBJECTIVE:To assess the efficacy and safety of tranexamic acid administration in total hip arthroplasty using meta-analysis. METHODS:Clinical randomized control ed trials concerning tranexamic acid application in total hip arthroplasty published from January 1969 to December 2013 were retrieved from the PubMed, Ovid, Elsevier, Cochrane library, China National Knowledge Infrastructure and Wanfang database. Intraoperative blood loss, postoperative blood loss, total blood loss, al ogeneic transfusion rate and incidence of venous thromboembolism were compared using meta-analysis between the tranexamic acid and control groups. Detection and literature references were used as supplementary data. RevMan 5.0 software provided by Cochrane col aboration was used for meta-analyses. Conclusion was obtained according to analysis. The analysis checked the heterogeneity of data. RESULTS AND CONCLUSION:After comprehensive and rigorous screening, 19 high-quality (Jadad score not less than 3) randomized control ed studies were included. Meta-analysis results demonstrated that compared with the control group, tranexamic acid decreased the total blood loss [weighted mean difference (WMD)=-341.04, 95%confidence interval (CI) (-508.10,-173.97), P<0.001], intraoperative blood loss [WMD=-63.26, 95%CI (-111.33,-15.18), P=0.01] and postoperative blood loss [WMD=-229.53, 95%CI (-338.11,-120.94), P<0.000 1], and diminished al ogeneic transfusion rate [relative risk=0.45, 95%CI (0.35, 0.57), P<0.000 1] in patients undergoing total hip arthroplasty. No significant difference in incidence of venous thromboembolism was detectable. These data suggested that tranexamic acid could reduce blood loss and transfusion rate in patients undergoing total hip arthroplasty without increasing the risk of incidence of venous thromboembolism.

Objective: To compare and observe the clinical efficacy of ALP and PFNA in treatment of intertrochanteric fractures, to provide clinical evidence for such patients. Methods:The clinical data of 122 cases patients with intertrochanteric fractures admitted to our department from January, 2012 to January, 2013 was analyzed retrospectively. 72 patients treated with PFNA were regarded as the study group and 50 patients with ALP as controls group. Two groups were compared with surgical incision, blood loss, operative time, healing time, hip functional recovery and postoperative complications. Results: The incision length, blood loss, operative time, postoperative weight-bearing activity time, fracture healing time, Harris score and complications of study group were significantly better than the control group (P<0.05), with statistical significance. Conclusion: The long-term efficacy of PFNA and ALP has no difference, but PFNA has smaller wound, less bleeding, sooner fracture healing time and weight-bearing activities and better early results.

Objective To investigate the effect of Bazhen granules combined with conventional treatment in patients with polymyalgia rheumatica and effect on immune level.MethodsFrom December 2013 to May 2016 in the second hospital of Shandong University 80 cases with polymyalgia rheumatica were randomly divided into the Banzhen granule group and the conventional group, 40 cases in each group.The two groups were given basic treatment with prednisone.The Bazhen granules group were given Bazhen granules at the same time.The two group were given continuous treatment for 3 months.ResultsBefore treatment, the difference of serum ESR and CRP levels between the Bazhen granules group and the normal group was not statistically significant.After treatment, in the Bazhen granule group, serum ESR, CRP levels were lower than those in the conventional group, the difference was statistically significant (P<0.05);serum CD3+, CD4+, CD4+/CD8+, IgG, IgM, IgA levels were higher than those in the conventional group (P<0.05), CD8+ level was lower than that in the conventional group (P<0.05).The effective rate in the Bazhen granule group 85%was higher than that in the conventional group 62.50% (P<0.05).The total effect rate in the Bazhen granule group95% was higher than that in the conventional group 87.50%, but the difference was not statistically significant.ConclusionThe effect is better that Bazhen granules combined with conventional treatment on the treatment of patients with polymyalgia rheumatica, which can improve the patient's immune level.

Objective To explore the role of miR-184 in Oxygen-Glucose-Deprivation (OGD) induced SK-N-SH cell ischemic injury and its regulation on AKT2 level. Method We used a combination of oxygen and glucose deprivation to imitate ischemic conditions in vivo. MiR-184 mimic and inhibitor were transfected into SK-N-SH cell to alter miR-184 levels. The expression of miR-184 and AKT2 were determined by using Real-time PCR. The extent of SK-N-SH cell survival rate was assessed by thiazolyl blue tetrazolium bromide (MTT) assay. Result Here, we observed that miR-184 was significantly inhibited in SK-N-SH cell after OGD (P<0.05). The changes of miR-184 level altered the expression of AKT2 mRNA. In addition, alteration of miR-184expressionsignificantly affected cell survival rate after OGD. Conclusion miR-184 plays an important role in ischemic injury through negatively regulating AKT2 level, which may provide a potential therapeutic target for ischemic stroke in miRNA levels.

Idiopathic pulmonary fibrosis(IPF), as one of the chronic and complex diseases, is with high incidence and mortality rate. It is also a difficult to treat disease in modern medicine. Traditional Chinese medicine (TCM) syndrome differentiation and treatment embodies characteristics and advantages. In recent years, the collateral disease theory guiding the prevention and treatment of the chronic and complex diseases has become a hot point and frontier in medical research, and achieved certain effects. This article is to summary the structures and functions of pulmonary collaterals based on the collateral disease theory. Combined with clinical manifestations of IPF, we put forward Fei-Re Luo-Y u as the fundamental role in the pathogenesis of IPF in its acute phase to lay the theoretical foundation to the further exploration of syndrome prevention and differentiation on IPF in its acute exacerbation.

Objective To study the CT and MRI features of the chordoma in the mobile spine.Methods The CT and MRI fea-tures were retrospectively analyzed in twenty-four cases of chordoma in the mobile spine.Results In all the twenty-four cases,bone lesions were solitary in eight cases and multiple in sixteen cases,mostly occurred in cervical,occasionally occurred in thoracic or lum-bar vertebra.Both vertebral body and part appendix were involved in all cases.CT imaging showed that all the lesions mainly mani-fested as osteolytic bone destruction,peripheral osteosclerosis and the cortical bone were incomplete.Soft-tissue mass involved para-vertebral and intraspinal.Five lesions appeared vertebrae compression.Eight lesions appeared intervertebral foramen expansion.Le-sions appeared honeycomb or annular enhancement after contrast media injection.Lesions were presented as heterogeneous slightly hypo-isointensity on T1 WI,hyperintensity on T2 WI.Low signal fibrous septa within the tumors were seen.Lesions appeared hon-eycomb enhancement after Gd-DTPA injection.Conclusion CT and MRI findings of chordoma in the mobile spine can be regarded as characteristic,which are helpful for clinical diagnosis.
