Short-term outcomes of three- and two-field lymphadenectomy with minimally invasive esophagectomy for esophageal cancer: a propensity score-matching analysis.

Background: Whether patients can benefit from three-field lymphadenectomy (3-FL) in minimally invasive esophagectomy (MIE) remains unclear. This study retrospectively compared short-term outcomes between 3-FL and two-field lymphadenectomy (2-FL) in MIE for patients with esophageal cancer (EC) and aimed to evaluate the clinical significance of 3-FL.

Methods: There were 284 patients enrolled in the study (124 patients with 3-FL and 160 patients with 2-FL).

Associations of interleukin-4 and interleukin-4 receptor loci with esophageal squamous cell carcinoma susceptibility.

Some functional polymorphisms in immune-regulating genes could affect the development of esophageal squamous cell carcinoma (ESCC). We enrolled 721 patients with ESCC and 1,208 healthy controls to explore the roles of rs2227282 (C > G) and rs2243283 (C > G) loci in the interleukin-4 (IL4) gene and rs1801275 loci in the interleukin-4 receptor (IL4R) gene for the occurrence of ESCC. As for IL4, the single nucleotide polymorphism rs2227282 (C > G) conferred an overall decreased risk for ESCC (adjusted P = 0.

Association of Polymorphisms with Susceptibility to Non-Small-Cell Lung Cancer in the Chinese Population.

Studies have reported that and () polymorphisms may be associated with the risk to different cancers. However, the correlation between those variations and non-small-cell lung cancer (NSCLC) is still unclear. A total of 1,003 NSCLC patients and 901 noncancer controls were recruited in the study, to confirm the association of variations in gene with the risk of NSCLC.

Assessment of , , and Genetic Polymorphisms in Esophageal Squamous Cell Carcinoma Susceptibility in the Eastern Chinese Han Population: A Case-Control Study Involving 2351 Subjects.

Previous studies suggested that alterations in the energy metabolism might be underlying cancer initiation and progression. Polymorphisms of genes involved in energy metabolism regulation, such as (), (), and (), might confer susceptibility to esophageal squamous cell carcinoma (ESCC) and partially explain its pathogenesis. We investigated the effects of several single nucleotide polymorphisms (SNPs) in three metabolic-related genes (e.

Association of Long Noncoding Polymorphisms with the Risk of Esophagogastric Junction Adenocarcinoma: A Three-Center Study of 1063 Cases and 1677 Controls.

Increasing evidence suggested that long noncoding () variants may be involved in the progression of various cancers. However, the association of the polymorphisms with the risk for esophagogastric junction adenocarcinoma (EGJA) is still unknown. In this case-control study, we selected two cancer-related polymorphisms (rs944289 C > T and rs7990916 C>T), and recruited a total of 1063 EGJA patients and 1677 noncancer controls to determine whether the rs944289 C > T and rs7990916 C > T polymorphisms could influence EGJA susceptibility and lymph node status.

Sewage treatment by a low energy membrane bioreactor.

A new membrane bioreactor (MBR) was developed for treatment of municipal wastewater. The MBR was mainly made up of an activated sludge reactor and a transverse flow membrane module, with an innovative configuration being in application between them. As a result, the transverse flow membrane module and low recirculation flow rate created advantages, such as lower energy consumption and more resistance to membrane fouling.

Determination and discussion hydraulic retention time in membrane bioreactor system.

Based on the microorganism kinetic model, the formula for computing hydraulic retention time in a membrane bioreactor system (MBR) is derived. With considering HRT as an evaluation index a combinational approach was used to discuss factors which have an effect on MBR. As a result, the influencing factors were listed in order from strength to weakness as: maximum specific removal rate K, saturation constant Ks, maintenance coefficient m, maximum specific growth rate mu m and observed yield coefficient Yobs.

Influence of supplemental nutrient on aerobic decolorization of acid red 14 in activated sludge.

Azo dyes are non-biodegradable in the textile effluent under aerobic condition. This study demonstrates that the addition of nutrients leads to degradation of a selected azo dye (AR14), and the major decolorization kinetic pathway of AR14 could be expressed as a pseudo first order kinetic model under the experimental conditions used in this study. An excellent correlation was obtained between the decolorization speed and additional nutrient concentration, as indicated by a coefficient of determination (r2) of 0.
