The material basis of bitter constituents in Carbonized Typhae Pollen, based on the integration strategy of constituent analysis, taste sensing system and molecular docking.

The discovery of bitter constituents is of great significance to the exploration of medicinal substances for they have potential physiological effects. Carbonized Typhae Pollen (CTP), which is a typical example of carbonized Traditional Chinese Medicine (TCM), has a bitter taste and hemostatic effect after carbonized processing. The objective of this study is to elucidate the material basis of bitter constituents in CTP.

Quality Control Circle Practices to Improve Mask-Wearing Compliance by Patients Diagnosed with Tuberculosis During External Examinations.

Objective: The purpose of this study is to examine the effect of quality control circle (QCC) activities on increasing the mask-wearing compliance of hospitalized patients diagnosed with tuberculosis (TB) during external examinations.

Methods: To assess the mask-wearing compliance of patients diagnosed with TB admitted to a ward in our hospital in 2019, who visited other departments, we conducted activities in accordance with the ten steps of the QCC. We outlined the causes of non-compliance and developed and implemented improvement plans.

[Applicability of odor analyzer based on study of processed ginger products and GC-MS validation].

Heracles Ⅱ rapid electronic odor analyzer has been gradually applied in the study on the "odor" of Chinese medicine because of its ability to associate volatile substances in the sample with "odor", but its applicability is not clear. In this article, processed ginger products--dried ginger, roasted ginger, and carbonized ginger were chosen as examples to study the volatile chemical components, and the applied scope and accuracy of Heracles Ⅱ rapid electronic odor analyzer were verified by gas chromatography-mass spectrometry(GC-MS). Components in ten batches of ginger from different producing places were detected by GC-MS and Heracles Ⅱ rapid electronic odor analyzer.

The Role of Cholinesterase in Differential Diagnosis between Gastric Cancer and Benign Gastric Diseases.

Background: Gastric cancer is the fifth most common malignancy worldwide. In early stages, no obvious symptoms are usually observed in gastric cancer patients, and it is especially hard to distinguish gastric cancer from benign gastric diseases, resulting in delayed diagnosis and poor prognosis. Common biomarkers of gastric cancer, such as CEA and CA19-9, are also elevated in benign diseases.

One-Pot Synthesis of High-Quality AgGaS/ZnS-based Photoluminescent Nanocrystals with Widely Tunable Band Gap.

Herein, we present a facile colloidal method to synthesize the high-quality AgGaS nanocrystals (NCs) within 2 min via exploiting the high-reactivity S precursor and then extend this synthetic strategy to the preparation of AgGaS/ZnS core-shell NCs by a one-pot method without prior purification of AgGaS core. The as-synthesized samples were structurally characterized to confrim the formation of AgGaS/ZnS core-shell NCs. The energy band gap of the AgGaS/ZnS NCs can be effectively tunable from 2.

Efficiency analysis of using tailored individual doses of radioiodine and fine tuning using a low-dose antithyroid drug in the treatment of Graves' disease.

Purpose: To evaluate the effect of using tailored individual doses of radioiodine (¹³¹I) and fine tuning using low-dose antithyroid drug (ATD) in the treatment of Graves' disease, and an attempt to establish a therapeutic strategy that can keep both high rate of euthyroidism and low incidence of hypothyroidism.

Methods: The dose of radioiodine was calculated using the calculated dose formula, and low-dose ATD was used as a way of fine tuning during follow-up. The intended dose of radioiodine was modified according to the patient's age at radioiodine therapy, thyroid size, and duration of hyperthyroidism before radioiodine therapy in the study group; it was set as 2.
