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).
Carbonaceous aerosols, comprising organic carbon (OC) and elemental carbon (EC), are critical component of fine particulate matter (PM), with diverse impacts on air quality and human health. This study investigated the concentrations and seasonal patterns of carbonaceous species in PM during both the heating season (January 2021) and non-heating season (July 2021) in three coal-fueled cities in northern China, as well as the differences in carbonaceous aerosols and their associations with socioeconomic parameters in cities situated on either side of the "Hu Line" in China. The results showed that, owing to intensified coal combustion and unfavorable meteorological conditions, levels of OC, EC, and OC/EC ratios were higher in winter compared to summer.

Sintilimab, as a programmed death receptor-1 inhibitor, has exhibited a fine performance in treating NSCLC. However, the efficiency of sintilimab combined with chemotherapy for stage IIIA/IIIB NSCLC remains inconclusive.

However, there is still a lack of consensus on the extent of lymphadenectomy in MIE. The objective of this study was to investigate the safety and efficacy of three-field lymphadenectomy (3-FL) in MIE, compared with the standard two-field lymphadenectomy (2-FL).

There is a lack of high-level evidence on which type of treatment should be employed for these patients and the role of salvage surgery has not been well reported in the literature.
Methods: A retrospective analysis of patients who underwent salvage surgery in our center between January 2016 and June 2019 for advanced NSCLC after targeted therapy was performed.
An atypically large, free-floating thrombus extending from primary pulmonary malignancy into the left atrium (LA) is a rare phenomenon. Here, we report a 61-year-old man presenting with a large mass in the lower lobe of the left lung, extending to LA via the left inferior pulmonary vein.The thrombus remained clinically silent and was detected by computed tomography (CT) and transthoracic echocardiography.

The aim of this study is to explore inhibitory effect of recombinant human endostatin injection (endostar) on lymphangiogenesis in non-small cell lung cancer (NSCLC) tissue and its effect on circulating tumor cells (CTC) in peripheral blood.
Methods: Tumor-bearing model nude mice were divided into eight groups randomly (n=7), including control group, cisplatin group, several concentration endostar groups and endostar plus cisplatin groups. Continuous administration of Endostar for two weeks, observed one week after the end of administration.
