A new nomogram prediction model for pulmonary embolism in older hospitalized patients.

Purpose: Diagnosing pulmonary embolism (PE) in older adults is relatively difficult because of the atypical clinical symptoms of PE in older adults accompanied by multiple complications. This study aimed to establish a nomogram model to better predict the occurrence of PE in older adults.

Methods: Data were collected from older patients (≥65 years old) with suspected PE who were hospitalized between January 2012 and July 2021 and received confirmatory tests (computed tomographic pulmonary angiography or ventilation/perfusion scanning).

Long non‑coding RNA HHIP‑AS1 inhibits lung cancer epithelial‑mesenchymal transition and stemness by regulating PCDHGA9.

The aim of the present study was to investigate the effect of hedgehog‑interacting protein antisense RNA 1 (HHIP‑AS1) on epithelial‑mesenchymal transition (EMT) and cellular stemness of human lung cancer cells by regulating the microRNA (miR)‑153‑3p/PCDHGA9 axis. Reverse transcription‑quantitative PCR was used to compare the expression of HHIP‑AS1 in lung cancer and adjacent normal lung tissues. In addition, the correlation of HHIP‑AS1 with E‑cadherin, Vimentin, N‑cadherin and Twist1 was analyzed.

Lapiferin protects against H1N1 virus-induced pulmonary inflammation by negatively regulating NF-kB signaling.

H1N1 virus-induced excessive inflammatory response contributes to severe disease and high mortality rates. There is currently no effective strategy against virus infection in lung. The present study evaluated the protective roles of a natural compound, lapiferin, in H1N1 virus-induced pulmonary inflammation in mice and in cultured human bronchial epithelial cells.

Effect of kaolin on floc properties for reactive orange removal in continuous coagulation process.

Magnesium hydroxide was used as a coagulant for treating reactive orange wastewater in a real continuous process. Effects of kaolin on coagulation performance and floc properties were investigated with controlled experiments through floc size distribution, zeta potential, scanning electron microscopy and Fourier transform infrared spectroscopy. Kaolin had significant influence on magnesium hydroxide-reactive orange floc formation and growth.

[Heavy metal concentrations and pollution assessment of edible crops grown on restored manganese mine lands in Guangxi, South China].

A survey on the crops grown on the restored manganese mine lands in Pingle and Lipu of Guangxi was conducted, and the heavy metal concentrations in the edible parts of the crops were analyzed. The results showed that the heavy metal concentrations in the crops were 1.18-20.
