OBJECTIVE To explore the relationship between severe cardiotoxicity caused by oxaliplatin combined with capecitabine and genetic polymorphism, thereby providing references for safe clinical medication use. METHODS Clinical pharmacists conducted a correlation analysis on a case of severe cardiotoxicity in a rectal cancer patient at Qilu Hospital of Shandong University following first-time treatment with standard doses of oxaliplatin combined with capecitabine. Case reports of cardiotoxicity caused by oxaliplatin and capecitabine were retrieved from the Chinese and English databases such as CNKI and PubMed.Basic patient information, drug treatment plan, and cardiotoxic manifestations were extracted and summarized. Combined with the patient’s genetic polymorphism test results related to the metabolism and excretion of platinum-based and fluorouracil drugs, potential mechanisms and prevention strategies for cardiotoxicity induced by oxaliplatin and capecitabine were discussed. RESULTS The patient exhibited homozygous mutations in ABCB1 C3435T and G2677T/A, a heterozygous mutation in MTHFR A1298C, and a heterozygous mutation in GSTP1 A105G, indicating impaired metabolism and excretion of oxaliplatin and capecitabine. The pharmacists recommended discontinuing oxaliplatin and reducing capecitabine to 50% of the original dose for subsequent treatment. The physicians adopted this advice, and the patient experienced no further severe adverse reactions with stable disease progression. CONCLUSIONS Oxaliplatin and capecitabine may cause severe cardiotoxicity. Medical institutions with adequate resources should perform genetic polymorphism test related to drug metabolism and excretion in patients prescribed these agents. For patients with multiple gene mutations, close monitoring and appropriate dose reductions are recommended to ensure medication safety and efficacy.

OBJECTIVE To evaluate the cost-utility of ciclesonide (CIC) versus budesonide (BUD) for the maintenance treatment of mild to moderate bronchial asthma. METHODS From the perspective of Chinese health service system, a Markov model was established based on the data from a clinical trial in China and some literature. The cycle length was 1 week, the time horizon was 60 years. A discount rate of 5% per year was applied. Cost-utility analysis was performed on therapeutic scheme of CIC and BUD using three times of China’s per capita gross domestic product (GDP) in 2023 as the threshold of willing-to-pay (WTP). One-way sensitivity analysis, probabilistic sensitivity analysis and scenario analysis were applied to test the uncertainty of basic analysis. RESULTS Compared with BUD scheme, the incremental cost of the CIC scheme was 9 401.67 yuan, and the incremental quality-adjusted life years(QALYs) were 0.001 3; incremental cost-effectiveness ratio (ICER) was 6 928 868.26 yuan/QALY, far beyond the threshold of WTP 268 074 yuan/QALY. One-way sensitivity analysis showed that the usage, dosage and unit price of CIC and BUD were parameters that had a significant impact on ICER; probabilistic sensitivity analysis showed that the basic analysis results were relatively robust; scenario analysis showed that, when the price of CIC reduced to 159.95 yuan/branch, the probability of CIC scheme having economics was similar to that of BUD scheme. CONCLUSIONS At the current price, CIC is not economical compared with BUD for the maintenance treatment of mild to moderate asthma, using three times of China’s GDP in 2023 as the threshold of WTP.

ObjectiveTo investigate and explore the characteristics and influencing factors of glucose metabolism in children with β-thalassemia major (β-TM) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). MethodsThe follow-up data of 41 patients with β-TM who underwent HSCT at Hematopoietic Stem Cell Transplantation Department of Children's Medical Center of Sun Yat-sen Memorial Hospital, Sun Yat-sen University were retrospectively analyzed. Their glucose metabolism characteristics were evaluated through laboratory tests and the related influencing factors were analyzed. ResultsIn the study, 41.46% (17/41) of patients developed abnormal glucose homeostasis after HSCT. Among them, 82.35% (14/17) characterized by insulin resistance, but no cases of diabetes mellitus were found. The results of insulin releasing test and oral glucose tolerance test(OGTT) showed that 45.00% (9/20) of patients had abnormal insulin releasing curve and 40.0% (8/20) had delayed serum glucose peak. The average age of HSCT in abnormal glucose homeostasis group was significantly older than that in the normal glucose homeostasis group [(8.8±3.9) years old vs (6.0±3.1) years old, P=0.015]. ConclusionsPatients with β-TM after HSCT may develop abnormal glucose homeostasis, consists largely of insulin resistance. The elder age of HSCT (≥7 years old) is a risk factor for abnormal glucose homeostasis in β-TM patients after HSCT. It is recommended to regularly monitor glucose metabolism indicators in β-TM children after HSCT, especially in elderly transplant recipients.

Objective To investigate the prevalence status and influencing factors of metabolic syndrome (MS) in adult patients with hypopituitarism (HP) during hospitalization. Methods The data of adult HP patients who received treatment in the hospital were collected from March 2021 to March 2024. The prevalence status of MS in adult HP patients was counted, and logistic regression analysis was adopted to analyze the influencing factors of MS in adult HP patients. Results Among the 308 adult HP patients in this study, 121 cases developed MS and 187 cases did not develop MS, and they were included in the MS group (n=148) and the non-MS group (n=232). The incidence of MS in adult HP patients was 38.95% (148/380). Compared with the non-MS group, the levels of high-density lipoprotein cholesterol, serum total cholesterol and low-density lipoprotein cholesterol in the MS group were higher, the waist circumference was larger, and the growth hormone was lower (P<0.05). After logistic regression analysis, it was found that high-density lipoprotein cholesterol (OR=1.069, 95%CI: 1.010-1.132, P=0.021), total serum cholesterol (OR=1.065, 95%CI: 1.014-1.119, P=0.012), low-density lipoprotein cholesterol (OR=1.055, 95%CI: 1.005-1.108, P=0.031), waist circumference (OR=1.063, 95%CI: 1.006-1.123, P=0.030) and growth hormone (OR=1.077, 95%CI: 1.019-1.138, P=0.009) could independently affect the occurrence of MS in adult HP patients (P<0.05). Conclusion Adult HP patients during hospitalization are often complicated with MS. High-density lipoprotein cholesterol, serum total cholesterol, low-density lipoprotein cholesterol, waist circumference, and growth hormone are factors affecting the occurrence of MS in adult HP patients.

Probiotics play a crucial role in colon cancer treatment by metabolizing prebiotics to generate short-chain fatty acids (SCFAs). Colon cancer patients are frequently propositioned to supplement with probiotics to enhance the conversion and utilization of prebiotics. Nevertheless, the delivery and colonization of probiotics is hindered by the harsh conditions of gastrointestinal tract (GIT). Here, we devised a straightforward yet potent modified prebiotic-based "shield" (Gelatin-Inulin, GI), employing dietary inulin and natural polymer gelatin crosslinked via hydrogen bonding for enveloping Lactobacillus reuteri (Lr) to formulate synbiotic hydrogel capsules (Lr@Gl). The GI "shield" serves as a dynamic barrier, augmenting the resistance of Lr to gastric acid and facilitating its bioactivity and adherence in the GIT, synergizing with Lr to elicit an anti-tumor effect. Simultaneously, Lr@GI demonstrates anti-tumor effects by depleting glutathione to release reactive oxygen species, accompanied by the activation of NLRP3 (NOD-like receptor family pyrin domain containing 3), and the induction M1 macrophage polarization. Furthermore, Lr@GI can not only promote the recovery of intestinal barrier but also regulate intestinal flora, promoting the production of SCFAs and further exerting anti-tumor effect. Crucially, Lr@GI also potentiates the anti-tumor effect of 5-Fluorouracil. The construction and synergistic anti-tumor mechanism of synbiotic hydrogel capsules system provide valuable insights for gut microbial tumor therapy.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.
