Aconitum (Ranunculaceae) has a long-standing history in traditional Chinese medicine (TCM), where it has been widely used to treat conditions such as rheumatoid arthritis (RA), myocardial infarction, and heart failure. However, the potency of Aconitum alkaloids, the primary active components of Aconitum, also confers substantial toxicity. Therefore, assessing the efficacy and toxicity of these Aconitum alkaloids is crucial for ensuring clinical effectiveness and safety. Metabolomics, a quantitative method for analyzing low-molecular-weight metabolites involved in metabolic pathways, provides a comprehensive view of the metabolic state across multiple systems in vivo. This approach has become a vital investigative tool for facilitating the evaluation of their efficacy and toxicity, identifying potential sensitive biomarkers, and offering a promising avenue for elucidating the pharmacological and toxicological mechanisms underlying TCM. This review focuses on the applications of metabolomics in pharmacological and toxicological studies of Aconitum alkaloids in recent years and highlights the significant role of metabolomics in exploring compatibility detoxification and the mechanisms of TCM processing, aiming to identify more viable methods for characterizing toxic medicinal plants.

To investigate the current situation and demand for specialized development of allergy nursing in 88 hospitals in Guangdong Province, as well as to provide evidence for the management of allergy nursing. From August to December 2023, a cross-sectional study was conducted to analyze the core managers of allergy nursing-related work in eighty-eight hospitals in Guangdong Province supported by the Allergy Nursing Branch of the Guangdong Nurses Association and the Nursing Group of the Allergy Branch of the Guangdong Medical Association. An online survey was conducted using the Delphi method to compile a questionnaire on the current status and demand for specialized development of allergy nursing in Guangdong Province. Chi-square tests and Fisher′s exact probability method were used to analyze the differences in the current status of specialty technology applications and the development and demand of specialized nursing between hospitals with or without allergy specialty departments. The results showed that among the eighty-eight hospitals in the nineteen prefecture-level cities surveyed in Guangdong Province, 17 hospitals (19%) had established allergy specialty departments, all of which were top-tier tertiary hospitals. The establishment duration [ M ( Q1, Q3)] was 3 (1, 10) years. The implementation rates of skin prick test (94%, 16/17), in-vitro examination (82%, 14/17), nasal endoscopy (82%, 14/17), subcutaneous specific immunotherapy (82%, 14/17), multidisciplinary consultation (65%, 11/17), fractional exhaled nitric oxide detection (47%, 8/17), skin patch test (41%, 7/17), and autologous serum skin test (35%, 6/17) in hospitals with allergy department were higher than those in hospitals without allergy department [59%, 42/71 ( χ 2= 7.462, P=0.006)], [54%, 38/71 ( χ 2= 4.717, P=0.030)], [51%, 36/71 ( χ 2= 5.599, P=0.018)], [34%, 24/71 ( χ 2= 13.177, P<0.001)], [24%, 17/71 ( χ 2= 10.505, P=0.001)], [24%, 17/71 ( χ 2= 5.540, P=0.019)], [11%, 8/71 (Fisher′s exact test, P=0.008)], [11%, 8/71 (Fisher′s exact test, P=0.025)]. In the development plan of allergy nursing in the next two years, hospitals that had set up allergy departments had a higher proportion in adding nurses (82%, 14/17, χ 2= 13.177, P<0.001), formulating specialized nurse training plans (71%, 12/17, χ 2= 3.980, P=0.046), formulating group standards or clinical guidelines (41%, 7/17, Fisher′s exact test, P=0.046), and formulating assessment standards (53%, 9/17, Fisher′s exact test, P=0.002). The demand for all aspects of allergy specialty nursing knowledge and skills accounted for more than 50%, and it was not related to whether the hospital set up an allergy department. In conclusion, the specialized development of allergy nursing in Guangdong province is still in its early stages, and there is a great demand for improving knowledge and skills in allergy. Further standardization of specialty construction is needed, along with the training of allergic nurses, to promote the comprehensive development of allergic reaction nursing specialties from point to area.

Objective:To systematically evaluate the efficacy and safety of carfilzomib in treating relapsed and/or refractory multiple myeloma (RRMM) in the real world.Methods:Relevant databases at home and abroad were searched (up to April 2023), and the literature on real-world studies of carfilzomib in the treatment of RRMM was collected. The quality of the literature was evaluated with the methodological index for non-randomized studies (MINORS) scale. Research data on the effectiveness and safety in RRMM patients treated with carfilzomib were extracted. The effectiveness indicators included the overall response rate (ORR), median progression-free survival (PFS), and overall survival (OS). The safety indicators included the incidence of adverse events (AEs) and the rate of treatment termination due to AEs, etc. Stata 13.0 software was used for meta-analysis of single proportions, and the occurrence of major adverse events was analyzed by descriptive statistics.Results:A total of 12 studies were entered, including 2 615 patients. The quality evaluation results showed that all of the 12 studies were with high quality. The meta-analysis of single proportions showed that ORR of carfilzomib in the treatment of RRMM was 75%[95% confidence interval ( CI): 68%-82%], the incidence of ≥ grade 3 AEs was 46% (95 %CI: 44%-49%), and the incidence of treatment termination due to AEs was 14% (95 %CI: 10%-19%). AEs with an incidence of >5% included thrombocytopenia, anemia, neutropenia, infection, hypertension, liver injury, and kidney injury. Conclusions:In the real world, the efficacy of carfilzomib in the treatment of RRMM is lower than that in clinical trials. The occurrence of infection during carfilzomib treatment and drug toxicity to the hematological system, cardiovascular system, liver, and kidney need to be paid attention to.

Objective:To investigate the correlation between serum gastrin, C-reactive protein (CRP), tumor necrosis factor α (TNF-α) and the degree of peptic ulcer bleeding.Methods:The clinical data of 90 peptic ulcer bleeding patients (test group) from April 2019 to September 2020 in Hangzhou Hospital of Zhejiang Medical and Health Group were retrospectively analyzed, including 15 cases with low-risk, 40 cases with intermediate-risk and 35 cases with high-risk of Blatchford score; 40 physical examination volunteers were selected as the control group during the same period. The serum levels of CRP and TNF-α were measured by enzyme-linked immunosorbent assay, and the serum level of gastrin was measured by radioimmunoassay. The correlation between CRP, TNF-α, gastrin and the Blatchford score was analyzed by Pearson method; the independent risk factors affecting high-risk peptic ulcer bleeding were analyzed by multivariate Logistic regression; the value of CRP, TNF-α and gastrin in predicting high-risk peptic ulcer bleeding was analyzed by the receiver operating characteristic (ROC) curve.Results:The CRP, TNF-α and gastrin in test group were significantly higher than those in control group: (19.69 ± 3.41) mg/L vs. (2.28 ± 0.64) mg/L, (26.63 ± 4.24) ng/L vs. (1.35 ± 0.31) ng/L and (149.77 ± 21.41) μg/L vs. (72.65 ± 12.39) μg/L, and there were statistical differences ( P<0.01). The hemoglobin and platelets in intermediate-risk and high-risk patients were significantly lower than those in low-risk patients: (59.21 ± 4.63) and (28.94 ± 4.69) g/L vs. (89.68 ± 5.12) g/L, (162.14 ± 12.47) and (122.05 ± 10.39) × 10 9/L vs. (213.58 ± 16.98) × 10 9/L, the indexes in high-risk patients were significantly lower than those in intermediate-risk patients, and there were statistical differences ( P<0.05); the prothrombin time, CRP, TNF-α and gastrin in intermediate-risk and high-risk patients were significantly higher than those in low-risk patients: (13.98 ± 1.29) and (16.97 ± 1.15) s vs. (11.00 ± 2.07) s, (18.87 ± 4.68) and (22.69 ± 2.96) mg/L vs. (15.45 ± 5.54) mg/L, (27.43 ± 5.05) and (31.02 ± 4.56) ng/L vs. (21.39 ± 8.54) ng/L, (140.89 ± 22.36) and (160.58 ± 25.52) μg/L vs. (121.39 ± 15.17) μg/L, the indexes in high-risk patients were significantly higher than those in intermediate-risk patients, and there were statistical differences ( P<0.05). Multivariate Logistic regression analysis result showed that hemoglobin, platelets, CRP, TNF-α and gastrin were independent risk factors for high-risk peptic ulcer bleeding ( OR = 0.224, 0.321, 3.687, 3.058 and 4.051; 95% CI 0.004 to 0.894, 0.121 to 8.547, 1.912 to 5.525, 3.012 to 10.609 and 2.012 to 7.525; P<0.05 or <0.01). Pearson correlation analysis result showed that CRP, TNF-α and gastrin were positive correlation with the Blatchford score ( r = 0.501, 0.526 and 0.542; P<0.01). ROC curve analysis result showed that the areas under the curve of CRP, TNF-α and gastrin for predicting high-risk peptic ulcer bleeding was 0.890, 0.825 and 0.901, with optimal cut-off values of 17.95 mg/L, 22.16 ng/L and 135.36 μg/L, sensitivity of 97.14%, 94.29% and 82.86%, and specificity of 80.00%, 66.67% and 86.67%. Conclusions:CRP, TNF-α and gastrin are correlated to the degree of peptic ulcer bleeding, and can be used as indexes to evaluate the bleeding degree of peptic ulcer.
