CT findings and clinical characteristics in distinguishing renal urothelial carcinoma mimicking renal cell carcinoma from clear cell renal cell carcinoma.

Background: We aimed to characterize the clinical and multiphase computed tomography (CT) features, which can distinguish renal urothelial carcinoma (RUC) mimicking renal cell carcinoma (RCC) from clear cell renal cell carcinoma (ccRCC) with collecting system invasion (CSI).

Methods: Data from 56 patients with RUC (46 men and 10 women) and 366 patients with ccRCC (262 men and 104 women) were collected and assessed retrospectively. The median age was 65.

China's Changing Alcohol Market and Need for an Enhanced Policy Response: A Narrative Review.

This study describes trends in alcohol consumption in the context of an expanding commercial context, current policy responses, and flaws in relation to international best practice for alcohol control in China. We surveyed the literature and other documents in Chinese or English up to December 2020 on policy responses to alcohol consumption and harm, industry structure, and marketing practices in China. Databases searched included PubMed, China National Knowledge Internet, Wanfang Data, Web of Science, and Baidu Scholar.

The industrial feasibility of low temperature DeNO in the presence of SO : a project case in a medium coking plant.

Catalyst poisoning by SO has hindered the industrial application of selective catalytic reduction (SCR) technology for the DeNO of low temperature flue gas for many decades. The current engineering process of placing the SCR unit after the desulphurization and dedusting units can lead to high project and operational costs owing to low DeNO efficiency at low temperatures. Based on our previous pilot results, a DeNO project case was built before the desulfurization unit in a medium coking plant to explore the industrial feasibility of low temperature DeNO in the presence of SO .

[High dose tamoxifen in the reversal treatment of multidrug resistance to EP regimen in patients with non-small cell lung cancer].

Background: To evaluate the reversal effect of high dose tamoxifen on multidrug resistance to EP regimen in patients with non-small cell lung cancer.

Methods: A total of 41 patients with NSCLC were studied, who were resistant to EP regimen and were proved to have P-gp protein overexpression. All patients were randomizedly divided into two arms.
