ABSTRACT
Ferroptosis， a new type of iron-dependent programmed cell death， is related to multiple pathways such as glutathione/glutathione peroxidase 4， iron metabolism， lipid metabolism， and iron autophagy， and plays an important part in the occurrence and development of many diseases， such as tumor， cerebral ischemia， and Parkinson's disease. Ferroptosis is a double-edged sword as it can eliminate pathological cells （such as tumor cells） but long-term ferroptosis may cause or aggravate other disorders related to abnormal lipid metabolism and iron metabolism. Regulating the balance between cell proliferation and ferroptosis may be an important target for drug intervention in diseases. The Yin-yang theory is one of the foundational principles of traditional Chinese medicine （TCM）， which is used to explain the physiological functions and pathological changes of human body and to guide the diagnosis and prevention of disease and health care. The balance of cell proliferation and programmed death is essentially the balance of Yin and Yang at the cellular level， which is governed and regulated by the law of balance. TCM intervenes in ferroptosis by promoting ferroptosis of tumor cells （damaging the excess） and inhibiting ferroptosis of other diseases （compensating the deficiency）， which is similar to the treatment principle of adjusting Yin and Yang. On this basis， this article aims to use the Yin-yang theory to clarify the relationship between TCM promoting ferroptosis and inhibiting ferroptosis， which is expected to lay a basis for the modern application of Yin-yang theory and provide new targets for TCM treatment.
ABSTRACT
Through the traditional Chinese medicine inheritance platform system, with the help of medical records, Ye Tianshi and Wu Jutong's medication characteristics for summer heat sickness were analyzed, the laws of the two people's medication were summarized, and the similarities and differences between the two were explored to explore the relationship. As a result, it was found that both of them recognized the relationship between summer heat and wetness, and Wu Jutong believed that "wind" was also an important pathogenic factor. Both of the patients were treated with cold medicine and warm medicine. They used mostly bitter, sweet, pungent taste and lungs, spleen, stomach, and heart meridian are the main components; two are commonly used Armeniacae Semen Amarum, Talcum, Rehmanniae Radix, Ophiopogonis Radix, Pinelliae Rhizoma and other drugs, Ye Tianshi use Scrophulariae Radix, Tetrapanacis Medulla, Coicis Semen and other drugs more, Wu Jutong use Gypsum Fibrosum, Sojae Semen Praeparatum, Menthae Haplocalycis Herba and other drugs more; at the same time, a combination of two high-frequency medicines used by two people has been excavated, and a new prescription has been deduced to provide a reference for further understanding and treatment of summer diseases.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the discrepancies between chemical constituents in Dao-di herb and non Dao-di herb of Huangqin (the root of Scutellaria baicalensis), study the impact of habitat and growth pattern (including cultivated and wild Huangqin) on chemical substances of Huangqin, and then provide evidence for the identification of Dao-di herb and quality evaluation of Huangqin.</p><p><b>METHOD</b>The chemical constituents in Huangqin collected from different habitats and under different growth patterns, were analyzed using HPLC fingerprint. The fingerprints obtained were then evaluated by hierarchical clustering analysis, principal component analysis and components peak area pattern.</p><p><b>RESULT</b>The fingerprints' chemical profiles of Dao-di herb and non Dao-di Huangqin had significant disparity. The fingerprints of modem Dao-di herb Huangqin samples originated from Chengde (Hebei Province) were significantly different from those from other habitats, though the fingerprints of the non Dao-di Huangqin collected from Chifeng (Inner Mongolia) and Chengde had high similarity to each other. The chemical characteristics of Huangqin samples collected from the habitats recorded in ancient herbals, such as Qingyang (Gansu Province), Yan'an (Shaanxi Province), Linyi (Shangdong Province), Changzhi and Jinzhong (Shanxi Province) were similar. The fingerprints of modern non Dao-di samples collected from Dingxi and Longnan (Gansu Province) and Shangluo (Shaanxi Province) had high similarity. In addition, the content of acteoside in wild Huangqin was higher than that in cultivated Huangqin.</p><p><b>CONCLUSION</b>Dao-di herb and non Dao-di herb of Huangqin could be distinguished using the developed HPLC fingerprints. The results obtained may provide evidence for the quality control and pharmcodynamical research of Dao-di herb and non Dao-di Huangqin.</p>

<p><b>AIM</b>To observe the effect of homocysteine (HCY) on the function of endothelium cell, and to discuss the possible mechanisms that Tongxinluo super powder affected.</p><p><b>METHODS</b>Healthy male Wistar rats were divided into randomly the control group, the model group, the Tongxinluo group. The effect of Ach on isolated rat thoracic aorta in vitro was examined, the microcirculation was observed by microcirculation meter, the activity of SOD and GSH-PX and content of NO, MDA, ET, Ang II, TXA2, PGI2 was detected.</p><p><b>RESULTS</b>Compared with control group, the effect of Ach on isolated rat thoracic aorta in vitro weakened markablely (P < 0.01), the format and percentage that capillary dilated declined significantly (P < 0.05), after treatment with Tongxinluo powder, the effect of Ach on isolated rat thoracic aorta in vitro was improved obviously (p < 0.01), and the format and percentage that capillary dilated were increased compared with model group; comparing with the control group, the level of Ang II and ET, TXA2 in plasm increased obviously (P < 0.05, P < 0.01), while the content of PGI2 depressed manifestly (P < 0.05), at the same time, both content of NO and activity of SOD, (GSH-PX declined obviously (P < 0.001, P < 0.05). After treatment with Tongxinluo powder, the level of ET, AngII and TXA2 reduced significantly in different degree (P < 0.01), while the content of PGI2 appeared stepping up notably (P < 0.01), and both activity of SOD and NO level increased obviously (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>(1) The high homocystein might cause the contracted and dilated function decreased, it might get involved in endothelium disfunction as a result of the massive free radicals production and diastolic-contract factors balance disorder induced by high homocystein. (2) Tongxinluo powder could improve the function of endothelium-dependment dilation induced by high homocystein, that associated with inhibitting the excessive production of free radicals, and improved function of endothelium.</p>
