Yilin Chen, Pan Chi
OBJECTIVE: To evaluate the efficacy of extralevator abdominoperineal excision (ELAPE) of rectal cancer. METHODS: PubMed, Cochrane Library and Embase database were searched for clinical studies comparing the ELAPE and abdominoperineal excision (APE) for rectal cancer between 2007 and 2016. Two reviewers independently screened the articles and extracted the data. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the observational studies and the score more than 5 points was the inclusion criteria...

Recently, attention has been focused on methotrexate-induced lymphoproliferative disease (MTX-LPD), and atypical phenotypes are occasionally documented. We encountered two patients with rheumatoid arthritis (RA) who were diagnosed with non-specific LPD (LPD-nos). Biopsy samples were not obtained during the initial examination when the LPD development was discovered, and the patients achieved a complete response after MTX cessation (case 1) or steroid pulse therapy (case 2). However, the tumors flared up 1.5 years later, and LPD-nos was determined following biopsies of the lymph node (LN, case 1) and liver (case 2)...

Robert Kantor, Ashley Kim, Jacob Thyssen, Jonathan I Silverberg
Previous studies found conflicting results about whether exposure to tobacco smoke is associated with increased atopic dermatitis (AD). We examined this association by systematic review and meta-analysis of MEDLINE, EMBASE, Scopus, and Cochrane Library and identified 86 studies, including 680,176 patients from 39 countries. A meta-analysis was performed using random-effects models to estimate pooled odds ratios (OR). Subset analyses were performed for different ages (children or adult), regions, study designs (cross-sectional vs...

Definitive diagnosis of cutaneous lymphoproliferative disorders is one of the most challenging issues in dermatopathology owing to the broad spectrum of clinical and histopathological presentations. We report a case of a 73-year-old woman who presented with a single, asymptomatic plaque limited to her left collarbone. This was followed by the appearance of several plaques and patches in addition to a tumor. Her initial biopsy suggested a CD4/CD8 double negative mycosis fungoides (MF). However, the rapidly progressive course of her disease is worrisome for peripheral T-cell lymphomas-not otherwise specified (PTCL-NOS)...

We evaluated the association between aerobic power (defined by peak oxygen consumption; VO2peak) and the contribution of nitric oxide synthase (NOS) to the sweating response in young and older individuals during exercise in the heat. Data from 44 young (24 ± 1 years) and 48 older (61 ± 2 years) males with mean VO2peak of 47.8 ± 2.4 (range, 28.0-62.3) and 39.1 ± 2.3 (range, 26.4-55.7) mLO2 kg(-1) min(-1), respectively, were compiled from our prior studies. Participants performed two 15- to 30-min bouts of exercise at a fixed rate of metabolic heat production of 400 or 500 W, each separated by 15-20 min recovery in the heat (35°C, relative humidity of 20%)...

Understanding different mechanisms contributing to the aggressive behaviour of epithelial ovarian cancer (EOC) is a large challenge. Interaction between inflammation, immunity and carcinogenesis occurs in different cancers; however, the potential roles of different molecules involved in these processes in relation to ovarian carcinogenesis were not fully investigated. Inducible nitric oxide synthase (iNOS) and interleukin-33 (IL-33) are implicated in carcinogenesis. iNOS is an NOS isoform that generates nitric oxide, which plays important roles in various stages of carcinogenesis...

BACKGROUND AND AIMS: Transient receptor potential vanilloid type 1 channel (TRPV1) is found to be expressed in endothelial cells (ECs) and activate endothelial nitric oxide synthase (eNOS). Recent studies implicate TRPV1 in attenuating inflammatory responses. However, the mechanisms underlying the beneficial effects remain unclear. In this study, we investigated whether TRPV1 suppresses inflammatory responses of ECs via eNOS/NO pathway. METHODS: Human umbilical vein endothelial cells (HUVECs) and renal microvascular endothelial cells (MVECs) isolated from deoxycorticosterone (DOCA)-salt hypertensive mice were cultured in the presence of capsaicin (CAP, a specific TRPV1 agonist) with or without the specific inhibitor of TRPV1, NOS, or Ca(2+)-dependent phosphatidylinositol 3-kinase (PI3K)/Akt pathway, before lipopolysaccharide (LPS) stimulation...

Thyroid hormones (THs) are important for normal reproductive function. Although 3,5,3'-triiodothyronine (T3) enhances follicle-stimulating hormone (FSH)-induced preantral follicle growth and granulosa cells development in vitro, little is known about the molecular mechanisms regulating ovarian development via glucose. In this study, we investigated whether and how T3 combines with FSH to regulate glucose transporter protein (GLUT) expression and glucose uptake in granulosa cells. Here, we present evidence that T3 and FSH co-treatment significantly increased GLUT-1/GLUT-4 expression, and translocation in cells, as well as glucose uptake...

Non-Hodgkin lymphomas (NHL) are a heterogeneous group of hematologic malignancies typically treated with multiagent chemotherapy. Rarely, spontaneous remissions can be observed, particularly in more indolent subtypes. The prognosis of aggressive NHL can be predicted using clinical and histopathologic factors. In aggressive B-cell NHL, the importance of MYC and BCL2 proto-oncogene coexpression (as assessed by immunohistochemistry) and high-grade histologic features are particularly noteworthy. We report a unique case of spontaneous remission in a patient with an aggressive B-cell NHL which harbored high-risk histopathologic features, including MYC protein expression at 70-80%, BCL2 protein expression, and morphologic features suggestive of high-grade B-cell lymphoma, NOS (formerly B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma [BCLU])...

BACKGROUND: Fluid therapy is a mainstay during the resuscitation of critically ill children. After initial stabilization, excessive fluid accumulation may lead to complications of fluid overload, which has been independently associated with increased risk for mortality and major morbidity in critically ill children. OBJECTIVES: Perform an evidence synthesis to describe the methods used to measure fluid balance, define fluid overload, and evaluate the association between fluid balance and outcomes in critically ill children...

BACKGROUND: Extracellular superoxide dismutase (ECSOD) protects nitric oxide (NO) bioavailability by decreasing superoxide levels and preventing peroxynitrite generation, which is important in maintaining renal blood flow and in preventing acute kidney injury. However, the profile of ECSOD expression after sepsis is not fully understood. Therefore, we intended to evaluate the content and gene expression of superoxide dismutase (SOD) isoforms in the renal artery and their relation to renal blood flow...
