Background: Asthma, a prevalent chronic inflammatory respiratory disease among children, was the focus of this study. Serum metabolism profiles were examined in patients diagnosed with both asthma and bronchiolitis by using ultra-high performance liquid chromatography-mass spectrometry.
Methods: In this study, the serum samples from three distinct groups-comprising patients diagnosed with asthma, bronchiolitis, and a healthy control group-underwent comprehensive non-targeted metabolomics analysis and targeted eicosanoid profiling.
We here describe a new method for distinguishing authentic from similar decoctions (namely, , , and ). Preliminary identification and analysis of four types of decoction pieces were conducted following the and local standards. Intelligent sensory data were then collected using an electronic nose, an electronic tongue, and an electronic eye, and chromatography data were obtained via high-performance liquid chromatography (HPLC).

Up to now, 196 national drug standards for Chinese medicine formula granules have been published by China, which guaranteed the production quality of Chinese medicine formula granules. However, there are still several challenges such as the rational application of national drug standards and the enrichment and improvement of varieties.

Chinese medicine dispensing granules, the result of the efforts to transform Chinese medicinal decoction pieces in China, features portability and ease of storage. Thus, it is destined to be an indispensible dosage form in the modernization drive of Chinese medicine. The Announcement on Ending the Pilot Project of Chinese Medicine Dispensing Granules was released in February 2021 and relevant regulations went into force in November 2021, which marks the a new journey for the development of Chinese medicine dispensing granules and the beginning of the "post-pilot era".

Firstly, fitted equations of water absorption and decocting time was established by observing the change laws of water absorption in 36 kinds of Chinese herbal pieces in 12 groups(according to the drug-parts) with decocting time. The r value of the mineral group and other type group was 0.

However, the existing traditional artificial identification and modern instrument detection in terms of accuracy and timeliness have both advantages and disadvantages. Therefore, how to quickly and accurately identify the quality of traditional Chinese medicine tablets has become a high-profile issue.

'Quality evaluation based on color grading' is one of the features used in Chinese medicine discrimination. In order to assess the feasibility of electronic eye (E-eye) in implementing 'quality evaluation based on color grading', the present study applied an IRIS VA400 E-eye to test 58 batches of Corni Fructus samples. Their optical data were acquired and combined with their corresponding classes.

It remains unknown whether excessive PTH secretion affects WAT browning and to what extent it contributes to body weight change in primary hyperparathyroidism (PHPT).
Methods: Using the adeno-associated virus injection, Pth gene over-expressed mice mimicking PHPT were firstly established to observe their WAT browning and body weight alteration.
Appetite is tightly controlled by neural and hormonal signals in animals. In general, steroid receptor co-activator 1 (SRC1) enhances steroid hormone signalling in energy balance and serves as a common co-activator of several steroid receptors, such as estrogen and glucocorticoid receptors. However, the key roles of SRC1 in energy balance remain largely unknown.

Four diterpenoids were obtained, including a novel compound: 1α-acetoxy-7α, 14β, 20α-trihydroxy-ent-kaur-16-en-15-one (1); together with three known compounds kamebakaurin (2), lasiokaurin (3), enmenol-1-β-glucoside (4). Their structures were elucidated on the basis of spectroscopic methods in conjunction with published data for their analogues.

Efforts have been focused on exploring the mechanism of the excessive ACTH production in non-pituitary tumors, whereas few studies have reported the molecular events underlying the tumor progression. In this study, seven patients with ACTH producing thymic carcinoids were enrolled.

This study was designed to gain insights into the molecular networks underlying the tumorigenesis of thymic carcinoids with ACTH secretion. By an approach integrating cDNA microarray and methods of computational biology, we compare gene expression profile between ACTH-producing thymic carcinoids and the normal thymus.
