Ethnopharmacological Relevance: The herbal formula Xiangdan injection and its modifications have been used in traditional Chinese medicine for about hundreds years to alleviate pain and promoting blood.
Aim: To investigate the anti-hypoxia active fraction of Xiangdan injection.
Materials And Methods: Xiangdan injection was extracted by ligarine, chloroform, acetic ether, n-butanol and water, represented respectively by A, B, C, D and E. Five extractions were group on the L12(2(5)) orthogonal designed table. NIH mices anti-hypoxia experiment under normal pressure with rats was adopted on the basis of orthogonal design, prediction pharmacodynamics model of TCM prescriptions was established, and the simulation bias was evaluated by combining two scatterplots. The anti-hypoxia active fraction of Xiangdan injection was determined by experiments.
Results: The prediction model of TCM prescriptions established in this study can predict the drug actions for different formulas, and PE%
Conclusion: As indicated in model prediction and experimental confirmation, the pharmacodynamic actions of the 5 formulas are all superior to that of the original formula, and ADE has the best effect.

Background: Danshen [Salvia miltiorrhiza Bunge (Lamiaceae; Salviae miltiorrhizae radix et rhizoma)] class injections (DSCIs) are widely used in the treatment of coronary heart disease (CHD). However, there are various types of DSCIs available on the market, and it remains uncertain which DSCI has the best clinical efficacy, as well as which one is most effective in regulating inflammatory markers and oxidative stress indicators. The aim of this network meta-analysis (NMA) is to compare the therapeutic effects of different DSCIs to identify the optimal DSCI for the treatment of CHD.

Xiangdan Injection are commonly used traditional Chinese medicine formulations for the clinical treatment of cardiovascular diseases. However, the trace components of Dalbergia odorifera in Xiangdan Injection pose a challenge for evaluating its quality due to the difficulty of detection. This study proposes a technology combining dispersive liquid-liquid microextraction and back-extraction (DLLME-BE) along with Bar-Form-Diagram (BFD) to address this issue.

Ethnopharmacological Relevance: Traditional Chinese medicine, with the feature of synergistic effects of multi-component, multi-pathway and multi-target, plays an important role in the treatment of cancer, cardiovascular and cerebrovascular diseases, etc. However, chemical components in traditional Chinese medicine are complex and most of the pharmacological mechanisms remain unclear, especially the relationships of chemical components change during the metabolic process.
Aim Of Study: Our aim is to provide a method based on complex network theory to analyze the causality and dynamic correlation of substances in the metabolic process of traditional Chinese medicine.
On-line screening and verification of haptens in Xiangdan injection combining chemical analysis with activity detection.

Xiangdan injection (XDI), as a well-known traditional Chinese medicine injection, is of great significance to treat cardiovascular and cerebrovascular diseases. The haptens causing allergic reactions are urged to be detected due to the adverse reaction. In this study, an efficient approach was established to rapidly identify and screen potential haptens in XDI for the first time by combining high performance liquid chromatography-diode array detector-electrospray ionization-ion trap-time of flight-mass spectrometry with human serum albumin-fluorescence detector (HPLC-DAD-ESI-IT-TOF-MS-HSA-FLD).
