[Study on anticoagulant material basis and mechanism of Trichosanthis Semen and its shell and kernel based on spectrum-effect relationship integrated molecular docking].

This study explored the anticoagulant material basis and mechanism of Trichosanthis Semen and its shell and kernel based on spectrum-effect relationship-integrated molecular docking. High performance liquid chromatography(HPLC) fingerprints of Trichosanthis Semen and its shell and kernel were established. Prothrombin time(PT) and activated partial thromboplastin time(APTT) in mice in the low-and high-dose(5, 30 g·kg~(-1), respectively) Trichosanthis Semen, the shell, and kernel groups were determined as the coagulation markers.

[Progress and prospect of application of traditional Chinese medicine fingerprint (specific chromatogram) in Chinese Pharmacopoeia (2010-2020)].

The Chinese Pharmacopoeia began to apply fingerprints (specific chromatogram) to quality control of traditional Chinese medicine in its 2010 edition, and in its 2015 and 2020 editions, new fingerprints (specific chromatogram) were added for improvement of the Pharmacopoeia-based national standards for drugs. This review analyzes the traditional Chinese medicine fingerprints (specific chromatogram) in Chinese Pharmacopoeia (2010-2020) in terms of the number of varieties listed, application of fingerprints (specific chromatogram), selection of evaluation method, determination method, the selection of extraction or preparation solvents of the test samples. With the expansion of the application of fingerprints (specific chromatogram), the evaluation indicators are constantly improving.

Establishment and validation of an SIL-IS LC-MS/MS method for the determination of ibuprofen in human plasma and its pharmacokinetic study.

In this work, we developed and validated a highly sensitive, rapid and stable LC-MS/MS method for the determination of ibuprofen in human plasma with ibuprofen-d3 as a stable isotopically labeled internal standard (SIL-IS). Human plasma samples were prepared by one-step protein precipitation. The chromatographic separation was achieved on a Poroshell 120 EC-C (2.

Using a stable isotope-labeled internal standard for liquid chromatography-tandem mass spectrometry quantitation of meloxicam in human plasma.

A sensitive and highly efficient LC-ESI-MS/MS method using a stable isotope-labeled internal standard (SIL IS) to detect meloxicam in human plasma was developed and validated. Sample preparation used only 50 μL human plasma with one-step methanol protein precipitation. A gradient mobile phase system was adopted for chromatographic separation on a Poroshell 120 SB-C column (2.

[Anti-platelet aggregation and anti-thrombotic mechanism of Trichosanthis Fructus combined with aspirin based on network pharmacology].

To explore the anti-platelet aggregation and anti-thrombotic mechanisms of Trichosanthis Fructus combined with aspirin based on network pharmacology and the validation of arteriovenous by pass model in rats. The databases of Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),Drug Repositioning and Adverse Drug Reaction Chemical-Protein Interactome(DRAR-CPI),Universal Protein Resource(Uniprot) and the Database for Annotation,Visualization,and Integrated Discovery(DAVID) were used to predict protein targets and analyze biological pathway and signal pathway in the combination of Trichosanthis Fructus with aspirin. The effects of pretreatment with Trichosanthis Fructus pellets,aspirin pellets and their combination on thromboxane B2(TXB2),6-keto prostaglandin F1α(6-keto-PGF1α) and cyclic adenosine monophosphate(c AMP) in rat thrombotic model were studied.

[Research progress on chromatographic fingerprint similarity evaluation method for traditional Chinese medicine in the past 30 years（1988-2017）and its prospect].

Over the past 30 years, the chromatographic fingerprint technology of traditional Chinese medicine (TCM) has been developed from academic discussion to application for the research and development of TCM which has promoted the technological innovation of Chinese medicine industry and the progress of quality standard of TCM. The similarity evaluation method of chromatographic fingerprint of TCM has played a key role in this process. According to the number of literature and research tendency in terms of the chromatographic fingerprint in the last 30 years, the chromatographic fingerprint evaluation could be divided into three stages: the direct comparison stage (1988-1999), similarity evaluation stage (2000-2009) and the similarity evaluation development stage (2010-2017).

[Effect of different data standardization methods on spectrum-effect relationship for anticoagulation of Trichosanthis Fructus dropping pills].

To study the effect of different data standardization methods on the spectrum-effect relationship for anticoagulant effect of Trichosanthis Fructus dropping pills. The spectrum-effect relationship was studied by using grey correlation degree method between three doses of Trichosanthis Fructus dropping pills and prothrombintime (PT) in mice. The effect of 10 data standardization methods, namely minimization method, maximum method, data extreme difference method, standard deviation standardization method, initialization transformation method, mean transformation method, ratio of each chromatographic peak area to the total peak area, ratio of each chromatographic peak area to the common peak area, logarithmic standardization method and tangent normalization method on the spectrum-effect relationship between Trichosanthis Fructus dropping pills and PT in mice was evaluated by using relative correlation degree as the index.
