[Research progress in Astragali Radix and its active ingredients in treatment of lung cancer].

Lung cancer is the leading cause of cancer death, and its effective treatment is a difficult medical problem. Lung cancer belongs to the traditional Chinese medicine(TCM) disease categories of lung accumulation, lung amassment, and overstrain cough. Rich theoretical basis and practical experience have been accumulated in the TCM treatment of lung cancer.

Case Report: Niraparib as Maintenance Therapy in A Patient With Ovarian Carcinosarcoma.

Ovarian carcinosarcoma (OCS) is a rare, highly aggressive and rapidly progressing malignant tumor with an extremely poor prognosis. So far, due to the low incidence of OCS, there are no large-scale prospective studies exploring the standard care of OCS patients. There is no uniform and effective treatment for OCS.

Hyperbaric oxygen therapy may be effective to improve hypoxemia in patients with severe COVID-2019 pneumonia: two case reports.

Objectives: To determine whether hyperbaric oxygen (HBO2) therapy be effective to improve hypoxemia for severe COVID-19 pneumonia patients.

Methods: Two male patients ages 57 and 64 years old were treated. Each met at least one of the following criteria: shortness of breath; respiratory rate (RR) ≥30 breaths/minute; finger pulse oxygen saturation (SpO2) ≤93% at rest; and oxygen index (P/F ratio: PaO2/FiO2 ≤300 mmHg).

An integrated 3D-printed platform for the automated isolation of N-glycans.

The development of techniques for the rapid analysis of N-glycans is a key step in enabling the roles of glycoproteins in biological processes to be studied. Analysis is usually performed through the liberation of the carbohydrate moieties from proteins, followed by fluorescent labeling and identification using either standardized HPLC or mass spectrometry techniques. A simple and robust automated process for the release and isolation of N-glycans would greatly improve analytical throughput and reproducibility, and is thus highly desirable.

2-Pyridylfuran: a new fluorescent tag for the analysis of carbohydrates.

We herein report the use of 1,3-di(2-pyridyl)-1,3-propanedione (DPPD) as a fluorogenic labeling reagent for sugars. Reaction of DPPD with the anomeric carbon affords a fluorescent 2-pyridylfuran (2-PF) moiety that permits the sensitive HPLC-based detection of monosaccharides. 2-PF-labeled monosaccharides can be easily separated and analyzed from mixtures thereof, and the reported protocol compares favorably with established labeling reagents such as 2-aminobenzoic acid (2-AA) and 1-phenyl-3-methyl-5-pyrazolone (PMP), ultimately allowing subfemtomole detection of the galactose-derived product.
