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.

OBJECTIVES: To study the impact of SURF4 expression level on long-term prognosis of gastric cancer (GC) and biological behaviors of GC cells. METHODS: SURF4 expression level in GC and its association with long-term patient prognosis were analyzed using publicly available databases and in 155 GC patients with low and high SURF4 expressions detected immunohistochemically. The Cox proportional hazard model and Kaplan-Meier survival curves were used to analyze independent prognostic predictors of GC and the 5-year survival rate of the patients with different SURF4 expression levels. Informatics analyses were conducted to explore the correlation of SURF4 expression level with immune cell infiltration in GC, SURF4-related differential genes and their associated pathways. In cultured GC cell line HGC-27, the effects of SURF4 knockdown and overexpression on proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) were investigated. RESULTS: Analysis of GEPIA dataset and immunohistochemical results suggested significant SURF4 overexpression in GC (P<0.05), which was associated with shortened 5-year survival time of the patients (χ²=38.749, P<0.001). The prognosis of GC was closely related to tumor stage T3-4, N2-3, CEA≥5 μg/L and CA19-9≥37 kU/L (P<0.05). SURF4 expression level was negatively correlated with activated B cells, NK cells and CD8⁺ effector memory T cells (P<0.05) and positively correlated with CD4⁺ T cells (P<0.05). GO and KEGG enrichment analysis suggested that SUFR4 may participate in GC carcinogenesis by promoting EMT through the tight junction pathway. In HGC-27 cells, SURF4 overexpression significantly decreased E-cadherin expression, increased N-cadherin expression, inhibited ZO-1 and claudin-1 expressions, and promoted cell proliferation, migration and invasion. CONCLUSIONS SURF4 is highly expressed in GC, and its overexpression is associated with a shortened 5-year survival of the patients possibly by enhancing tumor cell proliferation, migration and invasion via inhibiting tight junction proteins and promoting EMT.

  Objective  To analyze the current status of the development of adaptation guidelines in China, as well as their methodological quality and the reporting quality, in order to provide reference for the development of adaptation guidelines.  Methods  We searched and collected adaptation guidelines led by Chinese researchers or institutions from 2015 to 2023 from four electronic databases, China National Knowledge Infrastructure, WanFang Data Knowledge Service Platform, SinoMed and PubMed, extracted the basic information of the adapted guidelines, and assessed their methodological quality and reporting quality using the Appraisal of Guidelines for REsearch and Evaluation (AGREE) Ⅱ and RIGHT-Ad@pt tools.  Results  A total of 14 adaptation guidelines were included, mainly focusing on nursing (42.9%, 6/14), with the most frequently used adaptation method of ADAPTE (71.4%, 10/14), and with reference to pre-existing guidelines mainly from the United States, the United Kingdom, and international organizations. Assessment by the AGREE Ⅱ tool showed that the average methodological quality score of the adapted guidelines was 36.6%. The scores were relatively high in the domains of clarity of expression and rigor of formulation (44.4% and 54.9%), and lowest in the domain of applicability (15.3%). The results of the RIGHT-Ad@pt tool showed that the reporting quality of the adaptation guidelines was relatively good, with the highest reporting rate of 91.2% and the lowest of 35.3%, and the reporting rates of seven articles were higher than 70%.  Conclusions  Adaptation guidelines in China are still in their infancy, with a relatively small number and mainly focusing on the nursing field. The most commonly used adaptation method is the ADAPTE method. The methodological quality and reporting quality of adaptation guidelines need to be further improved, and more research should be conducted on the specific conditions and timing of adaptation guidelines development.

The essence of clinical practice guidelines lies in their recommendations. It is common to find strong recommendations supported by low-quality evidence in current published guidelines. There is a typical misunderstanding among medical professionals that without high-quality evidence, it is impossible to develop high-quality guidelines or only expert consensus can be developed. Based on the GRADE approach, this paper explains the concept and clinical significance of low-quality evidence, and introduces the methods for formulating recommendations based on low-quality evidence in guidelines, with the aim to provide reference for guideline developers and users in China.

In order to prepare monoclonal antibody to σ A protein of avian reovirus(ARV)and es-tablish a sandwich ELISA method for the detection of ARV pathogens.In this study,the σ A pro-tein of ARV was expressed as antigen by prokaryotic expression and used to immunize BALB/c mice.Then,stable hybridoma cell lines were screened,and monoclonal antibodies were prepared.A sandwich ELISA detection method based on monoclonal antibody of σA protein was established,and the sensitivity,specificity,repeatability,and accuracy were tested.The results showed that the recombinant plasmid pET-32a-σA was successfully constructed and well expressed in Escherichia coli.After immunizing mice,two hybridoma cell lines 6B3 and 8E11,which could secrete mono-clonal antibodies stably,were successfully prepared.Both monoclonal antibodies could react with natural ARV.One of the monoclonal antibodies secreted by 6B3 was selected as the capture anti-body and the ARV-positive chicken polyclonal antibody was used as the detection antibody.A sand-wich ELISA method was established to detect ARV by optimizing the reaction conditions.The specific test showed that the method only detected ARV pathogens and no other common chicken viral pathogens were detected.The detection limit was 7.72 X 102 EID50/mL of ARV antigen.The coefficient of variation of the intra-and inter-assay tests were less than 5.0％and the reproducibili-ty was good.Thirty samples were tested simultaneously by σA-sandwich ELISA and PCR,and the results were consistent with each other.In conclusion,a sandwich ELISA method based on the monoclonal antibody of σA protein was successfully established for the identification and detection of ARV,which provided a technical means for the accurate and rapid detection of ARV.

Objective:To investigate the clinical effects of chidamide combined with linperlisib in treatment of recurrent angioimmunoblastic T-cell lymphoma (AITL) after autologous stem cell transplantation (ASCT).Methods:The clinical data of 1 patient with recurrent AITL receiving treatment of chidamide combined with linperlisib after ASCT in Sun Yat-Sen University Cancer Center in March, 2021 were retrospectively analyzed, and the related literatures were reviewed.Results:The 55- year-old male patient was presented with fatigue, night sweats and emaciation. According to the results of pathology, immunohistochemistry and imaging after admission, this patient was diagnosed as AITL. After treatment with venbutuximab + CDP (cyclophosphamide + doxorubicin + prednisone) regimen, the patient achieved complete remission, and then ASCT was performed. After the transplatation, programmed death receptor 1 inhibitor was maintained for 4 courses of treatment. It recurred 16 months after ASCT, and the patient achieved partial remission after 1 course of chidamide combined with linperlisib, and achieved complete remission after 2 courses of treatment. Later, recheck of hepatitis B virus showed a quantitative increase after the self withdrawal of anti hepatitis B drugs, and then the primary treatment was suspended. The last follow-up time was March, 2024, and recheck results of whole body enhanced magnetic resonance imaging indicated recurrence.Conclusions:The combination of chidamide and linperlisib is effective and safe in treatment of recurrent ATIL after ASCT.
