Objective To select the components for quality control of Fructus Lycii based on the absorption of its extract. Methods To investigate metabolism of components of Fructus Lycii, everted rat gut sacs was carried out as well as the blood was taken from abdominal aorta,.and all samples were analysised by HPLC. Results There are twelve constituents absorbed between ileum and jejunum of rat , and four constituents were detected in the blood. Compound 2, 3, 4, 5, 6, 9, 10, 11 were absorbed in prototype forms in the intestine directly,and compound 1, 7, 8, 12 were new ones. On the other hand, four compositions(3, 7, 10, 13)could be absorbed into blood through analysis serum samples obtaining from aorta abdominalis of rats. Two of them (3, 10)could be absorbed directly by intestine, while(7)was absorbed into blood in new form . Conclusion Based on the intestinal absorption experiment and analysion of compsition in blood, components (3, 10, 13) can be the quality control ingredients of Fructus Lycii.

Objective This paper was to study the absorption and metabolism differences of intestine and liver for multicomponent licorice.Methods The components were identified with the UPLC-MS/MS. In situ closed-loop method was used to carry out the comparative experiments of absorption and metabolism differences between intestine and liver.Results 13 components were identified by UPLC-MS/MS. The absorption and metabolism results indicated some components in licorice water extract could be absorbed into blood and metabolism happened during this process. 14 metabolites were detected in the plasma sample. The hepatic metabolism results indicated many components could experience complex metabolism and more metabolites could be generated.Conclusions Liver was the major metabolism organ for licorice water extract and some components could be metabolized along with the absorption process in intestine. The absorption and metabolism differences between intestine and liver were significant.
3.Medication Ideas for Depression from Wenyang Jieyu Prescription
Chinese Journal of Experimental Traditional Medical Formulae 2024;30(6):58-65
Depression is a complex emotional and mental disorder. The traditional Chinese medicine (TCM) methods for treating depression mainly include soothing the liver and relieving depression. Our research team proposes that depression is caused by Yang Qi deficiency and obstructed Qi movement, which are closely related to neurological and psychological changes induced by early traumatic experiences. Therefore, we suggest that the treatment should focus on warming Yang, replenishing Qi, and promoting Qi movement and have formulated Wenyang Jieyu prescription based on Erxiantang for warming yang and Xiaoyaosan for relieving depression. The experiment with the mouse model of early trauma induced by maternal separation showed that Wenyang Jieyu prescription significantly improved the mouse activity and environmental exploration, reduced the immobility time in forced swimming and tail suspension tests, alleviated the behaviors such as aversion to darkness and fear of open space, enhanced social interaction and social cognitive abilities, altered decision-making biases, reduced depression-like behaviors, and improved the decision-making patterns. Additionally, the prescription lowered the serum level of cortisol, inhibited the cortisol surge in the dexamethasone/corticotropin-releasing hormone (Dex/CRH) test, up-regulated the expression of mineralocorticoid receptor (MR) and 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2) in the hippocampus, down-regulated the expression of glucocorticoid receptor (GR) and corticotropin-releasing hormone receptor 1 (CRHR1), inhibited the methylation of GR exon 1 and the expression of DNA methyltransferase 1 (DNMT1), and restored the negative feedback of the hypothalamic-pituitary-adrenal (HPA) axis. Furthermore, Wenyang Jieyu prescription up-regulated the protein level of brain-derived neurotrophic factor (BDNF), elevated the levels of postsynaptic density protein 95 (PSD95) and synaptophysin (Syn), decreased the cell apoptosis index and B-cell lymphoma (Bcl-2)-associated X (Bax)/Bcl-2 ratio, suppressed the expression of Caspase-3, and enhanced the neuroplasticity and anti-apoptotic capacity in the hippocampus. Considering the research results, related articles, and clinical experience, we conclude that depression should be treated with liver-soothing and depression-relieving herbs, which can be supplemented with spleen-invigorating and Qi-regulating herbs to alleviate depressive symptoms. The Yang-warming and kidney-tonifying herbs can be used to eliminate the root cause and prevent relapse. Additionally, the wind-dispersing herbs can be supplemented to regulate the Qi movement throughout the body, thereby enhancing the efficacy of depression-relieving treatment.

Objective:
To investigate the differences of clinicopathological features, diagnosis, treatment and prognosis between patients with extra-gastrointestinal stromal tumors (EGIST) and duodenal gastrointestinal stromal tumors (DGIST).
Methods:
A retrospective case - control study was performed. Case inclusion criteria: (1) tumor confirmed by histology and pathology; (2) primary tumor locating in the extra - gastrointestinal tract or duodenum; (3) without other synchronous tumors; (4) complete clinical and pathological data. Clinical data of 20 EGIST patients and 32 DGIST patients from March 2011 to September 2016 at Department of Gastrointestinal Surgery, Ruijin Hospital, Shanghai Jiaotong University School of Medicine were retrospectively collected and analyzed. The observational parameters included clinicopathological characteristics, treatment and prognosis conditions. Continuous data of abnormal distribution were expressed as median (range) and compared using the Mann-Whitney
