The hydrodynamics and their evolution on the Upper Yangtze Block during the Ordovician-Silurian transition period remain unclear. The present study is an assessment of how regional and global events may have influenced the hydrodynamic evolution based on a planar lamination investigation of the shales from the Upper Yangtze Block. Analyses of large thin sections and argon-ion polished thin sections using field emission-scanning electron microscopy(FE-SEM) showed that there are four types of planar lamination, namely, silty graded planar lamination(SGPL), silt-clay graded planar lamination(SCGPL), silt-clay interlaminated planar lamination(SCIPL), and paper-like planar lamination(PPL). SGPL is formed by turbidity current with a flow speed less than 15 cm/s. SCGPL is formed by turbidity currents with a flow speed less than 15 cm/s for normal grading type and 15-25 cm/s for alternating grading type. SCIPL has a continuum of sparsely spaced type, closely spaced type, and alternating type, which is formed by bottom current with an increasing flow speed from 15 to 25 cm/s to above 25 cm/s. PPL can be divided into normal grading and composite grading types. The former is formed by vertical settling, while the latter is formed by bottom current with a flow speed of 5-15 cm/s. Vertically, types of planar lamination varied from SGPL to PPL and then SCIPL manifesting the waxing and waning of flow speed with a positive excursion at graptolite biozone Metabolograptus extraordinarius(WF4) and a negative excursion at graptolite biozone Persculptograptus persculptus(LM1). The sudden decrease in flow speed across Linxiang and graptolite biozone Paraorthograptus pacificus(WF3) and the subsequent progressive increase from graptolite biozone Akidograptus ascensus(LM2)to graptolite biozone Demirastrites triangulatus(LM6) and to graptolite biozone Stimulograptus sedgwickii(LM8) during deposition of the Ordovician-Silurian transition succession on the Upper Yangtze Block were linked to th

Investigating the pharmacological basis and mechanisms of the anti-thrombotic effects of Paeoniae Radix Rubra， both pre- and post-stir-frying with rice wine

引用

Food Science and Human Wellness 2025年

作者： Jiaxu Zhang Jian Guan Ajiao Hou Wenying niu Haixue Kuang Liu Yang Hai Jiang Key Laboratory of Basic and Application Research of Beiyao， Heilongjiang University of Chinese Medicine， Ministry of Education

Paeoniae Radix Rubra (PRR) is a commonly used traditional Chinese medicine known for promoting blood circulation and alleviating pain. Stir-frying PRR with rice wine enhances its effectiveness in improving blood flow and resolving stasis. To explore the pharmacodynamic basis and mechanisms behind PRR's anti-thrombotic effects—both pre- and post-stir-frying—a comprehensive approach combining pharmacological research， metabolomics， and chemistry was employed. Fraction inter-cross validation experiments， pharmacological assessments， and metabolomic analyses confirm the efficacy of the fraction separation process. Wine-stir-fried PRR (WPRR) shows superior blood activation compared to PRR. PRR mainly affects the TCA cycle and sphingolipid metabolism pathways through its small molecules， enhancing coagulation and fibrinolysis systems' functionality. All the subdivided components of WPRR have anti-thrombotic effects， especially polysaccharides and oligosaccharides. WPRR improves thrombotic conditions in rat blood stasis by modulating arachidonic acid metabolism， TCA cycle， lipid status enhancement， and angiogenesis stimulation while regulating platelet adhesion and aggregation. In conclusion， compared with PRR， the main material basis for the blood-activating efficacy of WPRR has transformed from small molecule compounds to polysaccharide and oligosaccharide components. The action pathways of WPRR in exerting anti-thrombotic efficacy have increased. The polysaccharide components in WPRR might possess considerable potential for being developed into natural anti-thrombotic drugs.
