ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide (LPS)-induced acute lung injury (ALI), and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid (AA) in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight: normal group, model group, dexamethasone group (2 mg·kg-1), low-dose Yantiao prescription group (18 g·kg-1), and high-dose Yantiao prescription group (36 g·kg-1), with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days, and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to assess lung tissue pathology. The wet/dry weight ratio (W/D) and myeloperoxidase (MPO) activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry (LC-MS/MS). ResultsCompared with the conditions in the normal group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the model group was significantly increased (P<0.01). The alveolar structure in mice was severely damaged, with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased (P<0.01). The content of AA metabolites, including prostaglandin D2 (PGD2), prostaglandin E2 (PGE2), 11(S)-hydroxy-eicosatetraenoic acid [11(S)-HETE], and 5-hydroxy-eicosatetraenoic acid (5-HETE) in serum and lung tissue was significantly increased (P<0.05), while the content of 11,12-epoxyeicosatrienoic acid (11,12-EET) and 14,15-epoxyeicosatrienoic acid (14,15-EET) in serum was significantly decreased (P<0.01). Compared with the results in the model group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the dexamethasone group, low-dose Yantiao prescription group, and high-dose Yantiao prescription group was significantly reduced (P<0.05). Mild thickening of alveolar walls, scattered inflammatory cell infiltration, and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced (P<0.01). The content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum from the dexamethasone group was significantly decreased (P<0.05), while the content of 14,15-EET in serum significantly increased (P<0.01), and the content of 5-HETE in lung tissue significantly decreased (P<0.01). In the low-dose and high-dose Yantiao prescription groups, the content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum and lung tissue was significantly decreased (P<0.05), while the content of 11,12-EET in both serum and lung tissue was significantly increased (P<0.05). ConclusionYantiao prescription has significant protective effects against LPS-induced ALI, which are related to its regulation of AA metabolic pathways in vivo.

ObjectiveThis study explored the risk factors for malignant risks of pulmonary nodules based on clinical data,constructed an integrated traditional Chinese and Western medicine model for predicting malignant risks of pulmonary nodules, and visualized the prediction results by using a nomogram. MethodsBased on a cross-sectional survey study design,patients with pulmonary nodules who were hospitalized in the Department of Respiratory and Cardiothoracic Surgery of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2023 to January 2024 were included. The dataset was randomly divided into a training set and a validation set according to 7∶3. In the training set,predictive factors were selected through univariate Logistic regression analysis and Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis,and Logistic regression models were built. The discriminative ability,calibration,and clinical decision-making curves of the Western medicine model and the integrated traditional Chinese and Western medicine prediction model were compared to select the optimal model,which was then visualized in a nomogram. ResultsThis study included a total of 366 patients,and they were divided into a training set (258 cases) and a validation set (108 cases). Seven predictive factors were considered including age,preference for fatty and greasy foods,history of environmental or occupational exposure,Qi deficiency,Yang deficiency,nodule density,and nodule diameter. A Logistic regression model was constructed. A Western medicine model,defined as model1,was created using only age,history of environmental or occupational exposure,nodule density,and nodule diameter as predictive factors. In addition,an integrated traditional Chinese and Western medicine model,defined as model2,was created by adding preference for fatty and greasy foods, Qi deficiency,and Yang deficiency as predictive factors. Model2 demonstrated better predictive performance in both the training and validation sets. Its accuracy in training set was 0.740,with precision of 0.825, recall of 0.829, F1 score of 0.827, the area under the curve (AUC)of 0.865 (95% confidence interval (CI):0.815-0.915), and a Brier score of 0.122. The accuracy in validation set was 0.731, with precision of 0.776, recall of 0.831, F1 score of 0.803, AUC of 0.852 (95%CI:0.776-0.927), and a Brier score of 0.149. The calibration curve and decision-making curve analysis showed that this model exhibited good consistency and clinical utility in prediction. The equation for the malignant probability of pulmonary nodules was defined as p=

Chinese Medical Ethics 2025;38(2):187-194
Artificial intelligence (AI) robots, as a dynamic force sweeping the world, have demonstrated remarkable influence in the field of medical education since their inception. They have continuously participated in medical education through online-assisted teaching of medical theory, interpretation of imaging materials, clinical skills practice, and other forms, bringing new opportunities and challenges for the development of medical education. Concurrent with transforming the field of education, AI technology has also given rise to a series of ethical issues due to the constraints of technological logic, such as algorithmic discrimination, technological dependence, data privacy breaches, emotional communication crises among teaching subjects, and blurred power boundaries. While drawing on Western ethical principles, it is crucial to maintain a sober awareness of local issues, pay attention to the realistic relationship between Confucian bioethics and medical education in China, emphasize the value-oriented function of benevolence principle in mitigating physical and mental risks, and guide students to become adults in “achieving success”; improve the institutional construction guided by the principle of the value of life, resist the risks of educational AI technology, and achieve technological goodness; build a harmonious human-machine relationship by adhering to the principle of human nature to prevent the development risks of educational AI.

[Objective] To assess the data characteristics of quality monitoring indicators for red blood cell (RBC) preparations, so as to provide reference for continuous improvement of blood quality. [Methods] The quality inspection data of 6 types of RBC preparations from Chongqing blood center from 2019 to 2023 were summarized. For the same indicators, the numerical range of quality indicators was monitored by comparing different types of preparations with the national standard GB18469. The loss and/or damage to RBCs caused by different preparation process were compared, and the impact of different preparation processes on the quality of RBCs was discussed. [Results] The appearance and sterility test compliance rates of the six types of RBC preparations were both 100%, while the compliance rates of other items were all ≥75%. The compliance rate of hematocrit for suspended RBCs was the lowest at 75%, with a median of 0.52, which was close to the lower limit of GB18469, while the medians of hematocrit for the other types were all at the midline level of GB18469. The Hb content for different types of RBCs was significantly higher than the corresponding requirements of GB18469 (P<0.05). The hemolysis rate at the end of storage for different types of RBCs was significantly lower than the requirements of GB18469 (P<0.05). The 1 U leukoreduction process resulted in a hemoglobin content loss of about 5% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). The washing process resulted in a hemoglobin content loss of <3% and had no significant impact on the hemolysis rate at the end of storage (P>0.05). The concentration process resulted in a hemoglobin content loss of <3% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). [Conclusion] The impact of different processes on RBC preparations is within a controllable range and meets the requirements of GB18469. The quality monitoring data can provide a reference for clinical blood selection, effectiveness evaluation and revision of related standards.

7.Full-process management of liver transplantation for hepatocellular carcinoma
Organ Transplantation 2025;16(2):214-219
Hepatocellular carcinoma (HCC) is one of the most common cancers in clinical practice. Hepatectomy and liver transplantation are currently important treatment modalities for HCC. However, for patients with end-stage liver disease, liver transplantation is the optimal choice, as it can completely resect the tumor while restoring normal liver function. Nevertheless, clinical liver transplantation for HCC faces challenges such as a shortage of donor livers and a high risk of postoperative tumor recurrence and metastasis. How to select HCC patients for liver transplantation and effectively improve the prognosis of HCC liver transplantation has become a hot topic in clinical practice, involving multiple aspects from preoperative precise evaluation to long-term postoperative follow-up. Therefore, this article reviews the full-process management of HCC liver transplantation, including preoperative management, surgical management, postoperative management and the application of multidisciplinary comprehensive treatment in HCC liver transplantation, in order to provide references for improving the prognosis of HCC liver transplant recipients.

Diabetes mellitus (DM) is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells, posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs, including the eyes, heart, liver, kidneys, nerves, and feet, making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications, challenges such as high costs and adverse drug reactions remain. Thus, identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component, astragaloside Ⅳ, possesses various biological activities, including anti-inflammatory, antioxidant, and antiviral effects, as well as benefits for cardiac and cerebral function, nerve conduction, and myocardial protection. Meanwhile, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a crucial role in regulating oxidative stress, inflammatory responses, apoptosis, and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications, leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally, it highlights its protective effects on basic cardiac function, inhibition of retinal cell damage, improvement of cerebral nerve dysfunction, reduction of chronic kidney and liver damage, and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer, astragaloside Ⅳ, in the treatment of DM and its complications.
