Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

ObjectiveTo explore the molecular mechanism implicated in the treatment of primary myelofibrosis (PMF) using Chinese medicinal herbs (CMH) by bioinformatics and molecular dynamics. MethodsData mining was performed to find the high-frequency CMH in treating PMF between the year of 1985 and 2024 by searching CNKI, Chinese Science and Technology Journal Database (CCD), and China Academic Journal Database (CSPD). TCMSP, SwissTargetPrediction and related reports were used to collect the main active ingredients of high-frequency CMH and their targets. The PMF datasets GSE44426 and GSE124281 were downloaded from GEO database, and R software was used for data normalization and differentially expressed genes (DEGs) screening. Key module hub genes were obtained by weighted gene co-expression network analysis (WGCNA) analysis. The common intersection genes of active ingredient targets, DEGs and key module hub genes of CMH were selected, and the target network was generated using Cytoscape 3.9.2 software. The core target network was generated by topological analysis, while key pathways were selected by GO and KEGG pathway enrichment analysis, and protein interaction relationships were obtained from the String database, so as to construct drug-ingredient-target network and protein interaction network (PPI) relationship diagrams. Discovery Studio 2020 software was used to perform molecular docking, and the GROMACS program was used to perform molecular dynamics simulation. ResultsA total of 21 prescriptions were collected involving 121 herbs. There were 9 herbs with a frequency ≥10 times, which were Danshen (Radix et Rhizoma Salviae Miltiorrhizae), Huangqi (Radix Astragali), Baizhu (Rhizoma Atractylodis Macrocephalae), Danggui (Radix Angelicae Sinensis), Dangshen (Radix Codonopsis), Gancao (Radix et Rhizoma Glycyrrhizae), Baishao (Radix Paeoniae Alba), Fuling (Poria) and Shudihuang (Radix Rehmanniae Praeparata) from high- to low-frequency. A total of 98 active ingredients and 1125 potential targets were obtained from 9 high-frequency CMH. GSE44426 and GSE124281 data sets screened out 24 gene samples, including 14 of the healthy control group and 10 of the PMF group, and identified 319 DEGs between the two groups, including 122 up-regulated genes and 197 down-regulated genes. WGCNA screened out 24 co-expression module genes and found that the five modules closely related to the onset of PMF were MEpink, MEdarkred, MEblack, MEgrey, and MEturquoise, involving 7112 key module hub genes. The GO and KEGG enrichment analyses indicated that lipids and the atherosclerosis pathways were mainly involved in the mechanism of above high-frequency CMH in treating PMF, which included six hub protein targets: HSP90AA1, HSP90AB1, SRC, MAPK1, IL1B and IL10. From the drug-ingredient-target network, seven active ingredients of CMH targeting at these six hub targets were found, including verbascoside, verbascos isoflavone, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The molecular docking and molecular dynamics analyses showed that the key CMH were Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and among the seven active ingredients, calycosin had the highest binding affinity with HSP90AB1. ConclusionThe main CMH for the treatment of PMF may be Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and the active ingredients include verbascoside, verbascos isoflavones, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The relevant targets are HSP90AA1, HSP90AB1, SRC, MAPK1, IL-10, and IL-1β, and the most critical pathways are lipid and atherosclerosis pathways.

OBJECTIVE To explore the effects of letrozole combined with methylprednisolone on clinical outcomes, ovarian reserve function, serum sex hormones, and safety in infertile patients with polycystic ovary syndrome resistant to clomiphene. METHODS The clinical data of 78 infertile patients with polycystic ovary syndrome resistant to clomiphene in the Department of Gynecology of Qingdao Central Hospital from February 2021 to January 2022 was analyzed retrospectively, and all patients were divided into control group (42 cases) and observation group (36 cases) based on the treatment methods. The control group took letrozole 5 mg/d orally on the 5th to 9th day of the menstrual cycle. Vaginal ultrasound was used to monitor the development of the endometrium and follicles; estradiol valerate was used to correct endometrial thickness, and measures such as inducing ovulation with follicle-stimulating hormone were taken to promote pregnancy. On the basis of treatment in the control group, the observation group began taking methylprednisolone orally at a dose of 4 mg/d starting from the third day of natural menstruation or withdrawal bleeding. Both groups were treated for 6 menstrual cycles. The ovulation and pregnancy within one year, serum levels of sex hormones [estradiol (E2), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone] and anti-Müllerian hormone (AMH), ovulation indicators (follicle growth time, the number of ovulations, and the number of dominant follicles), and the occurrence of adverse drug reactions were compared between the two groups. RESULTS After treatment, the biochemical pregnancy rate (72.22%) and clinical pregnancy rate (47.22%) of the observation group were significantly higher than those of control group (47.62%, 19.05%); the serum levels of E2, LH, FSH, testosterone and AMH were significantly lower than the control group; the follicle growth time was significantly shorter than the control group; the number of ovulation and dominant follicles were significantly higher than the control group (P<0.05). There was no statistically significant difference in ovulation rate (94.44% vs. 83.33%) and total incidence of adverse drug reactions (8.33% vs. 9.52%) between the observation group and the control group (P>0.05). CONCLUSIONS Compared with letrozole alone, the combination of letrozole and methylprednisolone can significantly improve the pregnancy rate, the sex hormone levels and ovarian reserve function in infertile patients with polycystic ovary syndrome resistant to clomiphene, with high safety profiles.

To investigate the clinical features and influencing factors for new-onset atrial fibrillation (AF) early after coronary artery bypass grafting. Methods The clinical data of 339 patients undergoing coronary artery bypass grafting in our hospital from January 2012 to January 2019 were retrospectively analyzed. There were 267 males and 72 females with an average age of 37-83 (58.03±8.90) years. The clinical features and influencing factors for new-onset AF after surgery were investigated. Results There were 234 patients of off-pump coronary artery bypass grafting (OPCABG), with 36 (15.4%) new-onset AF patients after operation, among whom 16.1% were males and 12.5% were females. There were 105 patients of on-pump coronary artery bypass grafting (CABG), with 39 (37.1%) new-onset AF patients, among whom 40.7% were males and 25.0% were females. The incidence was higher after the CABG surgery than that after the OPCABG surgery (37.1% vs. 15.4%, P<0.05). There was no statistical difference in the incidence rate between males and females (P>0.05). The incidence of new-onset AF after surgery was higher in ≥60 years patients for both operations (18.9% and 45.8%), which was significantly higher than that in <45 years patients (P<0.05). For both operations, the incidence of new-onset AF after surgery was high on the second day (24-48 h) after surgery, and most of the AF lasted for 1 day (P<0.05). The hypertension (OR=4.983, P=0.036), frequent premature atrial contraction or atrial tachycardia (OR=17.682, P=0.002), postoperative creatine kinase isoenzyme MB (CKMB) (OR=0.152, P=0.042), left anterior and posterior diameters (OR=17.614, P<0.001) and preoperative ejection fraction (OR=7.094, P=0.011) were influencing factors for new-onset AF after OPCABG. Diabetes (OR=11.631, P=0.020), other cardiac malformations (OR=29.023, P=0.002), frequent premature ventricular contraction or ventricular tachycardia (OR=0.047, P=0.001), and postoperative CKMB (OR=3.672, P=0.040) were influencing factors for new-onset AF after CABG. Conclusion The incidence of new-onset AF after CABG is higher than that after OPCABG, and it increases with age increasing. There is no difference in the incidence between males and females. The influencing factors for the two operations are different.
