Implanted bone marrow mononuclear cells (BMMCs) may promote both osteogenesis and angiogenesis in the femoral head. The aim of this study was to investigate the effectiveness of core decompression and implantation of BMMCs with porous hydroxyapatite bone filler for the treatment of osteonecrosis of the femoral head (ONFH). Patients with ONFH underwent core(More)
Tantalum rod implant following core decompression is reported to be effective in early stage of osteonecrosis of the femoral head (ONFH). The purpose of this study was to assess the survivorship and prognostic factors for radiographic progression and conversion to total hip arthroplasty (THA) after treatment with a modified tantalum implant technology. 59(More)
The purpose of this study was to evaluate the moderate survival data of porous tantalum rod implants for the treatment of osteonecrosis of the femoral head (ONFH). Additionally, some independent prognostic factors for conversion to total hip arthroplasty (THA) were identified. The porous tantalum rod population was obtained from a prospective, consecutive(More)
The aim of this study was to develop a scoring system for prediction of survival prognosis after surgery in patients with symptomatic metastatic spinal cord compression (MSCC) from non-small cell lung cancer (NSCLC). We retrospectively analyzed nine preoperative characteristics for survival in a series of 64 patients with NSCLC who were operated with(More)
This study aims to create and validate a score for survival and functional outcome of lung cancer patients with metastatic spinal cord compression (MSCC) after posterior decompressive surgery. The entire cohort of 73 consecutive patients was randomly assigned to a test group (N = 37) and a validation group (N = 36). In the test group, we retrospectively(More)
STUDY DESIGN A retrospective study. OBJECTIVE This study aims to develop a new scoring system that can guild surgeons to select the best candidates for decompressive surgery in patients with metastatic spinal cord compression (MSCC). SUMMARY OF BACKGROUND DATA Predicting survival and functional outcome is essential when selecting the individual(More)
Three structurally identical polymers, except for the number of fluorine substitutions (0, 1, or 2) on the repeat unit (BnDT-DTBT), are investigated in detail, to further understand the impact of these fluorine atoms on open circuit voltage (V(oc)), short circuit current (J(sc)), and fill factor (FF) of related solar cells. While the enhanced V(oc) can be(More)
BACKGROUND Previous studies have reported CD44 expression played an important role in the development and progression of tumor. The aim of study was to investigate whether single nucleotide polymorphisms (SNPs) of CD44 gene were associated with risk of non-small cell lung cancer (NSCLC), survival and occurrence rate of bone metastasis in patients with(More)
Simply mixing a Cu(II) salt and 6,6'-dihydroxy-2,2'-bipyridine (H2L) in a basic aqueous solution afforded a highly active water oxidation catalyst (WOC). Cyclic voltammetry of the solution at pH = 12-14 shows irreversible catalytic current with an onset potential of ~0.8 V versus NHE. Catalytic oxygen evolution takes place in controlled potential(More)
