RÉSUMÉ

OBJECTIVE@#Cultivated Cordyceps sinensis powder has been used as clinical drug and healthy food to nourish the lung and kidney, which solves the problem of serious shortage of wild C. sinensis. This study aims to explore the chemical components and compared their anti-fibrotic effects in cultivated C. sinensis.@*METHODS@#Nucleosides, sterols and polysaccharides were separated and purified from cultivated C. sinensis, and analyzed by high performance liquid chromatography, gas chromatography-mass spectrometry and chemical chromogenic methods, respectively. In high glucose-induced rat mesangial cell models, fibronectin and type 1 collagen were used as evaluation indicators.@*RESULTS@#There were 10 kinds of nucleosides and one sterol in cultivated C. sinensis. The contents of nucleosides, sterols and polysaccharides in the cultivated C. sinensis were close to 2%, 0.55% and 4.4%, respectively. Furthermore, nucleoside, sterol and polysaccharide components exhibited varying degrees of anti-fibrotic activity. The nucleoside components and sterol components inhibited the expression of extracellular matrix more effectively in the three main components.@*CONCLUSION@#Cultivated C. sinensis remains the similar compounds with the wild C. sinensis, and nucleosides and sterols may be the main active substances that contribute to its anti-fibrotic effects. The project of this study may provide valuable information on further optimization of more effective remedies with few side effects based on cultivated C. sinensis.

RÉSUMÉ

OBJECTIVE To analyze the dose-adjusted concentrations of Posaconazole oral suspension in patients undergoing hematopoietic stem cell transplantation (HSCT) and their influential factors. METHODS Data were collected from hospitalized HSCT patients admitted to the First Affiliated Hospital of Shandong First Medical University (Shandong Provincial Qianfoshan Hospital) from January 2021 to April whtwhm@yeah.net 2023 who took Posaconazole oral suspension for the prevention of invasive fungal disease (IFD) and received blood concentration of posaconazole. The rate of concentration attainment and clinical failure rate of posaconazole for the prevention of IFD were evaluated, and one-way and multiple linear regression analyses were performed for the influential factors of dose-adjusted concentrations (C0/D) of posaconazole. RESULTS A total of 44 patients were enrolled; the mean C0 of posaconazole in patients was (0.99±0.94) µg/mL, and 20 patients had a C0≥0.7 μg/mL, with a concentration attainment rate of 45.45% for the prevention of IFD; 13 cases were clinical failures, with a clinical failure rate of 29.55%. Of 24 patients who did not achieve C0/D of posaconazole for IFD prophylaxis, one patient was a clinical failure despite timely dose adjustment of posaconazole in seven patients; seven of the thirteen patients who did not undergo dose adjustment were clinical failures; and the remaining four patients were switched to other antifungal agents. The results of univariate analysis showed that gender, body mass index (BMI), renal function, combined use of sodium phenytoin, omeprazole and metoclopramide had a significant effect on the C0/D of posaconazole (P<0.05); the results of multivariate linear regression analysis showed that gender, BMI and combined use of sodium phenytoin were the independent factors affecting the C0/D of posaconazole (P<0.05). CONCLUSIONS Significant individual differences are reflected in the blood concentration of Posaconazole oral suspension; gender, BMI and combined use of sodium phenytoin are independent factors affecting the C0/D of posaconazole.
