Controversies existing over resurfacing the patella in total knee arthroplasty remain in the literature. The purpose of this review was to evaluate the effectiveness of resurfacing versus nonresurfacing the patella in total knee arthroplasty. We searched the Cochrane Library, MEDLINE and EMBASE for published randomised clinical trials relevant to patellar(More)
Controversies exist over which type of graft is best for the reconstruction of the anterior cruciate ligament (ACL). The purpose of this systematic review was to evaluate the effectiveness of ACL reconstruction using either hamstring (HT) autografts or bone-patellar tendon-bone (BPTB) autografts. We searched the Cochrane Library, MEDLINE and EMBASE for(More)
Dicer1, an RNase III endonuclease, is indispensable for the maturation of miRNA and siRNA, which control gene expression through the RNAi pathway. The diverse functions of miRNA involving multiple developmental processes have been elucidated, but the role of Dicer1 in spermatogenesis is just beginning to be revealed. Mice lacking Dicer1 were reported to be(More)
The objective of this study was to evaluate the effectiveness of hamstring (HT) autografts versus bone-patellar tendon-bone (BPTB) autografts for reconstruction of the anterior cruciate ligament (ACL). We searched the Cochrane Library, MEDLINE, EMBASE and the Chinese Biomedicine Database (CBM) for published randomised clinical trials (RCTs) relevant to ACL(More)
Salient object detection attracts much attention for its effectiveness in numerous applications. However, how to effectively produce a high quality binary mask from a saliency map, named saliency cuts, is still an open problem. In this paper, we propose a novel saliency cuts approach using unsupervised seeds generation and GrabCut algorithm. With the input(More)
CONTEXT Age-related cognitive decline has become an important public health issue. Tai Chi may be an effective intervention to protect the cognitive ability of healthy adults, but its effects are uncertain. This study systematically evaluated the protective effects of Tai Chi on healthy adults' cognitive ability. EVIDENCE ACQUISITION A systematic review(More)
OBJECTIVE To analyze the effectiveness of resistance exercise in the treatment of knee osteoarthritis on pain, stiffness, and physical function. DESIGN Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES PubMed, Embase, Cochrane Central Register of Controlled Trials, the Web of Science, and Chinese Biomedical Literature(More)
Altered immune response may be a part of the pathogenesis of preeclampsia. The few epidemiologic studies that have investigated the associations between genetic variations in the complement system genes and preeclampsia risk have reached inconsistent results. The aim of this study is to determine if polymorphisms in the complement system genes could(More)
Hepatitis B virus (HBV) intrauterine infection remains to be an important cause for a large number of persistent hepatitis B surface antigen (HBsAg) positive carriers in areas with a high HBV prevalence, particularly in China and Southeast Asia. In this study, the possible association between the HBV genomic heterogeneity and intrauterine infection was(More)
OBJECTIVE Pulmonary hypertension (PH) is characterized with pulmonary vasoconstriction and vascular remodeling mediated by 15-lipoxygenase (15-LO)/15-hydroxyeicosatetraenoic acid (15-HETE) according to our previous studies. Meanwhile, telomerase reverse transcriptase (TERT) activity is highly correlated with vascular injury and remodeling, suggesting that(More)
