Background: Nocardiosis poses a diagnostic challenge due to its rarity in clinical practice, non-specific clinical symptoms and imaging features, and the limitations of traditional detection methods. () is rarely detected in clinical samples. Metagenomic next-generation sequencing (mNGS) offers significant advantages over traditional methods for rapid and accurate diagnosis of infectious diseases, especially for rare pathogens.

Thirty male rats with adriamycin-induced renal fibrosis were randomized into model, low-, medium-, and high-dose Notoginseng Radix et Rhizoma, and positive control groups(n=6). Six clean SD male rats were selected into the normal group.

Baill (Wuweizi) are commonly utilized in traditional Chinese medicine for the treatment of cough and asthma. The synergistic effect of Mahuang-Wuweizi herb pair enhances their efficacy in alleviating respiratory symptoms, making them extensively employed in the management of respiratory disorders.

Due to lack of appropriate methods, pharmacological mechanisms of WTD acting on RA have not been fully elucidated. In this study, a list of putative targets for compositive compounds containing in WTD were predicted by drugCIPHER-CS.

As one of the most frequently used herbs in Traditional Chinese Medicine formulas that are prescribed for the regulation of bone and mineral metabolism, the therapeutic effects of Achyranthes bidentata on steroid-induced ONFH remain unclear. Thus, the aim of the current study was to verify whether Achyranthes bidentata extract (ABE) can be used to prevent steroid-induced ONFH and to investigate its underlying pharmacological mechanisms.

Methods: Eighty-five rats were divided into four groups: control, model, Huogu 15 g/kg and Huogu 30 g/kg. Six weeks later, animals were anaesthetized, femora was dissected for histopathological examination of the osteonecrotic changes and repair processes, micro computed tomography (Micro-CT)-based micro-angiography was performed to assess vascularization.
Steroid-induced osteonecrosis of the femoral head (steroid-induced ONFH) is characterized by increase of intraosseous pressure because of lipid metabolism disturbance such as elevation of adipogenesis and fat cell hypertrophy in the bone marrow, subsequently leading to disturbances of coagulation-fibrinolysis system in the femoral head and finally resulting in bone ischemia. Pravastatin has been demonstrated to be useful in preventing steroid-induced ONFH in animal models. However, its exact mechanisms acting on this disease have not been fully elucidated.
