Objective:To summarize the medication law and academic experience of Professor Yuan Jinsheng in the treatment of angina pectoris (AP) of coronary heart disease (CHD) through R language data mining technique.Methods:The effective outpatient medical records of Professor Yuan Jinsheng in the treatment of AP of CHD from January 1, 2016 to September 30, 2023 were selected, and the R 4.2.3 was used for frequency statistics, association rule analysis, systematic clustering analysis and correlation analysis of prescription drugs.Results:A total of 292 prescriptions were included, including 268 patients, involving 204 kinds of Chinese materia medica, and the total frequency of Chinese materia medica was 4 253 times. The main properties were warm and neutral, the main tastes were bitter, pungent and sweet, and the main meridians were spleen, lung and liver meridians. The analysis of association rules obtained 125 core TCM combinations, and the commonly used drug pair was Trichosanthis Fructus-Aurantii Fructus Immaturus. The core prescription composed of Aurantii Fructus Immaturus, Chuanxiong Rhizoma, Trichosanthis Fructus, Citri Reticulatae Pericarpium and Salviea Miltiorrhizae Radix et Rhizoma. Seven TCM groups of were obtained by systematic clustering analysis. Correlation analysis showed that the drug pairs with phi coefficient greater than 0.6 were in 8 groups.Conclusions:Studies suggest that AP of CHD is located in the heart, which is related to lung, spleen, liver and kidney, deficiency in root and excess in superficiality, phlegm, blood stasis and qi stagnation are important pathological factors. The treatment is based on the basic principles of tonifying qi, promoting yang, relieving rheumatism, resolving phlegm, activating blood circulation, and promoting qi circulation. It embodies Professor Yuan's academic thoughts and principles of differentiation and treatments of "taking fluency as the main point, regulating the five internal organs and weighing the root and superficiality".

BACKGROUND: T cell dysfunction, which includes exhaustion, anergy, and senescence, is a distinct T cell differentiation state that occurs after antigen exposure. Although T cell dysfunction has been a cornerstone of cancer immunotherapy, its potential in transplant research, while not yet as extensively explored, is attracting growing interest. Interferon regulatory factor 4 (IRF4) has been shown to play a pivotal role in inducing T cell dysfunction. METHODS: A novel ultra-low-dose combination of Trametinib and Rapamycin, targeting IRF4 inhibition, was employed to investigate T cell proliferation, apoptosis, cytokine secretion, expression of T-cell dysfunction-associated molecules, effects of mitogen-activated protein kinase (MAPK) and mammalian target of rapamycin (mTOR) signaling pathways, and allograft survival in both in vitro and BALB/c to C57BL/6 mouse cardiac transplantation models. RESULTS: In vitro , blockade of IRF4 in T cells effectively inhibited T cell proliferation, increased apoptosis, and significantly upregulated the expression of programmed cell death protein 1 (PD-1), Helios, CD160, and cytotoxic T lymphocyte-associated antigen (CTLA-4), markers of T cell dysfunction. Furthermore, it suppressed the secretion of pro-inflammatory cytokines interferon (IFN)-γ and interleukin (IL)-17. Combining ultra-low-dose Trametinib (0.1 mg·kg -1 ·day -1 ) and Rapamycin (0.1 mg·kg -1 ·day -1 ) demonstrably extended graft survival, with 4 out of 5 mice exceeding 100 days post-transplantation. Moreover, analysis of grafts at day 7 confirmed sustained IFN regulatory factor 4 (IRF4) inhibition, enhanced PD-1 expression, and suppressed IFN-γ secretion, reinforcing the in vivo efficacy of this IRF4-targeting approach. The combination of Trametinib and Rapamycin synergistically inhibited the MAPK and mTOR signaling network, leading to a more pronounced suppression of IRF4 expression. CONCLUSIONS Targeting IRF4, a key regulator of T cell dysfunction, presents a promising avenue for inducing transplant immune tolerance. In this study, we demonstrate that a novel ultra-low-dose combination of Trametinib and Rapamycin synergistically suppresses the MAPK and mTOR signaling network, leading to profound IRF4 inhibition, promoting allograft acceptance, and offering a potential new therapeutic strategy for improved transplant outcomes. However, further research is necessary to elucidate the underlying pharmacological mechanisms and facilitate translation to clinical practice.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

Objective To explore the safety and effects of alpha-lipoic acid (ALA) in patients with ischemic heart failure (IHF). Methods A randomized, double-blind, placebo-controlled trial was designed (ClinicalTrial.gov registration number NCT03491969). From January 2019 to January 2023, 300 patients with IHF were enrolled in four medical centers in China, and were randomly assigned at a 1∶1 ratio to receive ALA (600 mg daily) or placebo on top of standard care for 24 months. The primary outcome was the composite outcome of hospitalization for heart failure (HF) or all-cause mortality events. The second outcome included non-fatal myocardial infarction (MI), non-fatal stroke, changes of left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) from baseline to 24 months after randomization. Results Finally, 138 patients of the ALA group and 139 patients of the placebo group attained the primary outcome. Hospitalization for HF or all-cause mortality events occurred in 32 patients (23.2%) of the ALA group and in 40 patients (28.8%) of the placebo group (HR＝0.753, 95%CI 0.473-1.198, P＝0.231; Figure 1A-1C). The absolute risk reduction (ARR) was 5.6%, the relative risk reduction (RRR) associated with ALA therapy was approximately 19.4% compared to placebo, corresponding to a number needed to treat (NNT) of 18 patients to prevent one event. In the secondary outcome analysis, the composite outcome of the major adverse cardiovascular events (MACE) including the hospitalization for HF, all-cause mortality events, non-fatal MI or non-fatal stroke occurred in 35 patients (25.4%) in the ALA group and 47 patients (33.8%) in the placebo group (HR＝0.685, 95%CI 0.442-1.062, P＝0.091; Figure 1D). Moreover, greater improvement in LVEF (β＝3.20, 95%CI 1.14-5.23, P＝0.002) and 6MWD (β＝31.7, 95%CI 8.3-54.7, P＝0.008) from baseline to 24 months after randomization were observed in the ALA group as compared to the placebo group. There were no differences in adverse events between the study groups. Conclusions These results show potential long-term beneficial effects of adding ALA to IHF patients. ALA could significantly improve LVEF and 6MWD compared to the placebo group in IHF patients.

Objective To employ three dimensional high-resolution vessel wall magnetic resonance imaging(3D hr-VW-MRI)for analyzing the imaging characteristics of posterior circulation non-stenotic intracranial atherosclerotic plaque and to discuss its diagnostic value in identifying culprit plaques.Methods Ninety-three patients(age[62.94±9.70]years old,67 males,26 females)with non-stenotic atherosclerosis in our hospital from Jan.2019 to Jan.2021 were retrospectively recruited.The imaging features of plaques,including luminal area,maximum wall thickness and minimum wall thickness at the most stenotic site,stenosis rate,plaque burden,remodeling index,eccentricity index,enhancement ratio at the most stenotic site,and intraplaque hemorrhage,were measured based on T1-weighted imaging(T1WI)and contrast-enhanced T1WI.The culprit plaque was defined as a lesion arising from the responsible vascular supply area to a fresh infarction on the diffusion weighted imaging(DWI)and T2 fluid attenuated inversion recovery(T2-FLAIR)images with accompanying ischemic stroke/transient ischemic attack(TIA).A plaque was considered to be a nonculprit plaque when it occurred in patients with presumed ischemic stroke/TIA,but without an infarct on DWI and T2-FLAIR.Results Sixty-one culprit plaques and 32 non-culprit plaques were analyzed.The proportions of patients with hyperlipidemia,National Institutes of Health stroke scale(NIHSS)score,narrowest plaque enhancement rate,and incidence of intraplaque hemorrhage in the culprit plaque group were significantly higher than those in the non-culprit plaque group(all P＜0.05).Multivariate logistic regression analyses showed that NIHSS score(odds ratio[OR]=1.799,95％confidence interval[CI]1.303-2.484,P＜0.001),enhancement ratio(OR=1.076,95％CI 1.027-1.128,P=0.002)and intraplaque hemorrhage(OR=30.708,95％CI 2.563-367.925,P=0.007)were associated with plaque type.Conclusion NIHSS score,enhancement ratio at the most stenotic site,and intraplaque hemorrhage are independent risk factors for culprit plaques in patients with posterior circulation non-stenotic intracranial atherosclerotic disease.These indicators may help identify such culprit plaques and could be used to screen individuals with plaques having these characteristics,thereby providing a basis for early preventive interventions.

Vascular cognitive impairment is a group of disorders characterized by cognitive dysfunction caused by vascular factors. Disruption of the blood-brain barrier is an early pathophysiological mechanism of vascular cognitive impairment. Dynamic contrast-enhanced magnetic resonance imaging and arterial spin labeling-based blood-brain barrier imaging techniques can quantitatively assess the integrity of the blood-brain barrier. In recent years, these techniques have gradually been applied to detect the extent of blood-brain barrier dysfunction. This article provides a comprehensive review of the basic principles of relevant magnetic resonance techniques and the progress made in their application to the assessment of the blood-brain barrier in vascular cognitive impairment.

Objective:To investigate the impact of early blood glucose fluctuations after acute multiple injuries on post-traumatic stress disorder (PTSD).Methods:This study was a case-control study. From March 2022 to March 2023, patients with acute multiple injuries who were admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University were selected. According to whether complicated with traumatic brain injury (TBI), the patients were divided into TBI group and non-TBI group. Early post-traumatic blood glucose fluctuations were observed, including stress-induced hyperglycemia (SIH), initial blood glucose value on admission, blood glucose extreme, short-term glycemic variability (GV) and other related indicators. The 72-hour glucose coefficient of variation (Glu-CV) was used to reflect short-term GV. After 1 month, the PTSD checklist for DSM-5 (PCL-5) was used to assess the patient's symptoms of PTSD. The patients were divided into PTSD group and non-PTSD group according to PCL-5 score ≥38. The differences in short-term glucose fluctuations in each groups were compared; the risk factors of PTSD were analyzed by logistic regression; the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of related indicators on the incidence of PTSD.Results:159 patients with acute multiple injuries were selected and defined as the TBI group ( n=94) and non-TBI group ( n=65). The incidence of PTSD, PCL-5 scale scores, the incidence of SIH and 72 h Glu-CV in the TBI group were significantly higher than the non-TBI group (all P<0.05). The incidence of SIH and 72 h Glu-CV in the PTSD group were significantly higher than the non-PTSD group (both P<0.05). Multivariate logistic regression analysis showed that 72 h Glu-CV ( OR=1.333, 95% CI: 1.028-1.727, P=0.030) was the independent risk factor for PTSD after acute multiple injuries, and the area under the ROC curve was 0.861 (95% CI: 0.789-0.933, P<0.001), the sensitivity was 62.9% and the specificity was 93.5%. Conclusion:Patients with acute multiple injuries with TBI are more likely to have early glucose fluctuations and develop PTSD, and increased short-term glucose variability is the independent risk factor for PTSD after acute multiple injuries.

Objective To investigate the value of tranexamic acid combined with aspirin,low molecular weight heparin calcium in regulating inflammatory mediators and TEG in blood management of Total knee arthroplast(TKA).Methods 120 elderly patients with TKA in our hospital from January 2020 to October 2022 were randomly divided into group A(n=60)and group B(n=60).They were given tranexamic acid+aspirin and tranexamic acid+low molecular weight heparin calcium,respectively,for 2 weeks.Perioperative indexes,complications[lower limb deep vein thrombosis(DVT),intermuscular vein thrombosis(MCVT),incision infection],blood transfusion rate,adverse reactions(gastrointestinal discomfort,subcutaneous ecchymosis),TEG parameters[coagulation reaction time(R),blood coagulation time(K),maximum amplitude(MA),coagulation angle(α)],inflammatory mediators[soluble CD40 ligand(sCD40L),Toll-like receptor 4(TLR4),tumor necrosis factor(TNF-α)],vascular endothelial injury factors[soluble thromboregulatory protein(sTM),vascular endothelial cell growth factor(VEGF),E-selectin]were compared between the two groups.Results There was no significant difference in the 24 h postoperative drainage volume,latent blood loss,total blood loss,intraoperative blood loss,Hb and HCT levels 72 h after surgery between the two groups(P＞0.05).There was no statistically significant difference in TEG parameters between the two groups,at different time points,and between groups at different time points(P＞0.05);The serum levels of TLR4,sCD40L and TNF-α in group A were lower than those in group B 2 weeks after surgery(P＜0.05).The levels of plasma sTM and serum VEGF and E-selectin in group A were lower than those in group B 2 weeks after surgery(P＜0.05).There was no significant difference in the incidence of deep vein thrombosis(DVT),intermuscular vein thrombosis(MCVT),incision infection and blood transfusion rate between group A and group B(P＞0.05).There was no significant difference in the total incidence of adverse reactions between group A and group B(P＞0.05).Conclusion Compared with the combination of low molecular weight heparin calcium,the combination of tranexamic acid and aspirin can protect vascular endothelium and inhibit inflammatory response.However,both can maintain the patient's coagulation function and avoid massive blood loss or thrombosis.There is no significant difference in safety and effectiveness.
