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.

Objective This study aims to investigate the structure and anti-angiogenic activity of homogeneous polysaccharides in Honeysuckle flowers,constructing the theoretical basis for its widespread application.Methods Homogeneous Honeysuckle polysaccharide LF-02-2 was obtained through water extraction,alcohol precipitation,anion exchange chromatography,and gel permeation chromatography.The structure of LF-02-2 was deduced through molecular weight determination,monosaccharide composition analysis,sugar residue linkage analysis,partial acid hydrolysis,and sugar aldonic acid reduction combined with NMR data.Additionally,in vitro tube formation experiments using human microvascular endothelial cells(HMEC-1)were conducted to assess its anti-angiogenic activity.Results Structural analysis of LF-02-2 revealed a homogeneous polysaccharide with a weight-average molecular weight of 74.1 kDa.The monosaccharide composition included rhamnose(Rha),galactose(Gal),galacturonic acid(GalA),and arabinose(Ara)in molar ratios of 10.43:14.94:6.66:67.97.The main chain consisted of 1,4-linked α-Galp A,1,2-linked α-Rhap,and 1,2,4-linked α-Rhap.Branches were connected to O-4 of 1,2,4-linked α-Rhap and included β-Galp with terminal connections and 1,4,6-linked β-Galp and α-Araf with terminal and 1,5-linked connections.Tube formation experiments demonstrated that LF-02-2 significantly inhibited tube formation in human microvascular endothelial cells(HMEC).Conclusion LF-02-2,an RG-I pectic polysaccharide from Honeysuckle flowers,exhibited significant anti-angiogenic activity,suggesting its potential for development as an anti-angiogenic drug.

Objective:To analyze the advantages and disadvantages of online and offline laboratory medicine continuing education and training, and to discuss the future continuing education and training mode under new technology development and new situation.Methods:A questionnaire was administered to the trainees who participated in the 2019 and/or 2020 national continuing medical education project—Clinical Application and Evaluation of New Technologies and Methods of Laboratory Medicine—sponsored by the Department of Laboratory Medicine, West China Hospital, Sichuan University. One hundred and twenty-four questionnaires were completed for the 2019 offline training, and 503 questionnaires were completed for the 2020 online training. The rank sum test, Fisher's exact test, and chi-square test were performed for statistical analysis with the use of SPSS 26.0.Results:The participants in 2020 were significantly younger and the proportion of female participants in 2020 was significantly higher compared with those in 2019. Intermediate titles or above accounted for 66.93% (83/124) in 2019, and intermediate titles or below accounted for 88.67% (446/503) in 2020. The proportion of people from Sichuan Province was significantly higher in 2019. The proportion of trainees from primary institutions was significantly lower in 2019. In 2019, public institutions were mainly tertiary hospitals (74.31%, 81/109), and the majority of participants from private institutions were from third party testing institutions (60.00%, 9/15). In 2020, the percentage of tertiary hospitals in public institutions decreased to 60.99% (258/423), while the percentage of community medical institutions increased to 10.64% (45/423), and 75.00% (60/80) of trainees from private institutions were from tertiary and secondary medical institutions. Trainees with lower educational levels were more likely to appreciate the value of the training course, especially with higher degrees of satisfaction with improvements in theoretical levels and practical skills, and participants from primary institutions believed that the training course could effectively improve their theoretical and practical levels. The number of participants who provided suggestions on laboratory medicine continuing education and training needs in 2019 (83.75%, 67/80) was higher than that in 2020 (48.51%, 244/503). The overall pass rate of post-training assessment in 2020 was 88.52% (424/479).Conclusions:Online and offline training modes have different audience groups and training effects. Online continuing education can provide training opportunities to more primary care personnel and junior and intermediate professionals, which is conducive to improving the basic professional literacy and testing skills of laboratory personnel on the whole. At the same time, the integration of online and offline modes will promote the development of laboratory medicine continuing education.

Background: There is no standard cut-off value of serum IgG4 concentration and serum IgG4/total IgG ratio for the diagnosis of IgG4-related disease (IgG4-RD) or as a marker of treatment responses. We aimed to explore this issue through a retrospective cohort analysis of adults in southwest China. Methods: The diagnostic performance of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD was evaluated in a retrospective analysis of 177 adults newly diagnosed as having IgG4-RD and 877 adults without IgG4-RD. Dynamic analysis was performed to evaluate the significance of serum IgG4 concentration on IgG4-RD treatment responses. Results: The serum IgG4 concentration differed according to sex. The optimal cut-off values of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD diagnosis were 1.92 g/L and 0.12 in males and 1.83 g/L and 0.11 in females, respectively. For patients with serum IgG4 concentration >2.01 g/L, the cut-off values in the total population were >3.00 g/L and 0.19, respectively. The median serum IgG4 concentration decreased over time, and the decrease rate increased over time. The serum IgG4 concentration significantly decreased at >1 week post-treatment (P=0.004), and the median decrease rate was close to 50% at >4 weeks post-treatment. Conclusions Serum IgG4 can be a good indicator for IgG4-RD diagnosis; however, different diagnostic cut-off values should be determined according to sex. The decreasing rate is more conducive than the serum IgG4 concentration to monitor treatment efficacy. The IgG4/IgG ratio did not improve the diagnostic efficacy for IgG4-RD.

OBJECTIVE To develop a whole-process intelligent model of pharmaceutical care for peritoneal dialysis （PD） patients， and to provide a reference for clinical pharmacists to provide standardized PD pharmaceutical care. METHODS The pharmaceutical care mode of PD patients at home and abroad was investigated and analyzed. Based on the actual situation of the First Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”）， with “home→PD center outpatient→ inpatient department” as the main node， the recycling process of medication reconciliation was optimized. The whole-process intelligent pharmaceutical care model of PD was illustrated by improving the Chinese version of the drug-related problems （DRPs） classification tool， developing the corresponding pharmaceutical care process， and presenting specific cases. RESULTS Based on the medication therapy management （MTM） platform， our hospital had built a closed-loop PD whole-process intelligent pharmaceutical care model of “in-hospital pharmaceutical care （building document）-PD outpatient MTM-home pharmaceutical care （online App management）”. A “double cycle” workflow of “admission→discharge→outpatient” medication reconciliation cycle and “discovery-analysis-intervention-follow-up-record-evaluation” DRPs cycle was formed. CONCLUSIONS The establishment of the whole-process intelligent pharmaceutical care model for PD in our hospital provides experience for standardizing pharmaceutical care for PD patients， and can reduce DRPs.
