Objectives:To confirm whether neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are indicators for the prognosis of post-amputation patients with critical limb ischemia (CLI).Methods:In this retrospective observational study a total 270 post-amputation patients with CLI were included between January 2010 and December 2014 in the First Hospital of Jilin University, Changchun, China. The neutrophil and lymphocyte counts were recorded before amputations. Neutrophil-to-lymphocyte ratio was calculated and NLR ≥8.08 was defined as elevated. Logistic regression analysis was conducted to test the prognostic value.Results:According to the statistical analysis, it was indicated that NLR ≥8.08 (odds ratio [OR] 26.228, 95% confidence interval [CI]: 5.801-118.583, p<0.001), PLR ≥237.14 (OR: 3.464, 95% CI: 1.289-9.308, p=0.014) and coronary heart disease (OR: 2.739, 95% CI: 1.060-7.082, p=0.038) were the independent prognostic indicators for the patients.Conclusion:Neutrophil-to-lymphocyte ratio, PLR, and coronary heart disease are independent prognostic indicators for post-amputation patients with CLI.
Osteonecrosis is a condition that frequently affects patients with systemic lupus erythematosus (SLE). However, reports on severe multifocal osteonecrosis involving more than three anatomical sites in patients with SLE are scarce. The present study describes a case of SLE with multifocal osteonecrosis involving all four limbs. A 22-year-old woman was diagnosed with SLE in 2010 and the disease was controlled by treatment with methylprednisolone and hydroxychloroquine. Approximately 1 year following the diagnosis of SLE, the patient developed pain in the elbows and hips. Magnetic resonance imaging revealed evidence of multifocal osteonecrosis in the bilateral distal segments of the humerus and femoral head, the distal segment of the right femur and the proximal segment of the right tibia. The patient was treated with right total hip arthroplasty and core decompression of the right femur and tibia, followed by continuation of the earlier medical treatment for SLE. The present case highlights the importance of conducting a careful investigation of patients with SLE who present with multiple joint involvement, and the choice of the appropriate treatment according to the presentation.
Background: We aimed to discover potential gene biomarkers for gastric cancer (GC) diagnosis. Materials and Methods: Genechips of 10 GC tissues and 10 gastric mucosa (GM, para-carcinoma tissue, normal control) tissues were generated using an exon array of Affymetrix containing 30,000 genes. The differentially expressed genes (DEGs) between GC tissues and normal control were identified by the Limma package and analyzed by hierarchical clustering analysis. Gene ontology (GO) and pathway enrichment analyses were performed for investigating the functions of DEGs. Receiver operating characteristics (ROC) analysis was performed to measure the effects of biomarker candidates for diagnosis of GC. Results: Totals of 896 up-regulated and 60 down-regulated DEGs were identified to be differentially expressed between GC samples and normal control. Hierarchical clustering analysis showed that DEGs were highly differentially expressed and most DEGs were up-regulated. The most significantly enriched GO-BP term was revealed to be mitotic cell cycle and the most significantly enriched pathway was cell cycle. The intersection analysis showed that most significant DEGs were cyclin B1 (CCNB1) and cyclin B2 (CCNB2). The sensitivities and specificities of CCNB1 and CCNB2 were both high (p<0.0001). Areas under the ROC curve for CCNB1 and CCNB2 were both greater than 0.9 (p<0.0001). Conclusions: CCNB1 and CCNB2, which were involved in cell cycle, played significant roles in the progression and development of GC and these genes may be potential biomarkers for diagnosis and prognosis of GC.
The VEGF gene silencing could inhibit the cell proliferation, migration and invasion of RCC 786-O cells; inhibition of VEGF protein expression could prevent transplanted RCC growth and tumor angiogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
