Objective To investigate the factors associated with coronary microvascular dysfunction(CMD)after percutaneous coronary intervention(PCI)in diabetic patients with multivessel disease and non-ST-segment elevation acute coronary syndrome(NSTE-ACS).Methods A single-center retrospective study was conducted,including 242 diabetic patients with NSTE-ACS and multivessel disease who underwent PCI between January 2021 and June 2024 at Hospital.Baseline characteristics,procedural parameters,and laboratory indicators were collected.CMD was defined based on immediate postoperative coronary functional measurements[computational pressure-flow dynamics derived angiography fractional flow reserve(caFFR)＞0.80 and coronary angiography-derived index of microcirculatory resistance(caIMR)≥25].Univariate and multivariate logistic regression analyses were performed to identify risk factors for CMD.Results Among the 242 patients,49(20.2%)were diagnosed with patient-level CMD after PCI.The CMD group showed significantly higher hemoglobin levels compared to the non-CMD group[136.00(130.00,150.00)g/L vs.130.00(119.00,145.00)g/L,P=0.012],as well as higher glutamic-pyruvic transaminase levels[20.00(16.00,31.00)U/L vs.18.00(13.00,26.00)U/L,P=0.047].However,there were no significant differences between the groups in terms of diabetes duration,traditional cardiovascular risk markers(hypertension,smoking history,low-density lipoprotein cholesterol),types of hypoalycemic agents,or procedural parameters(all P＞0.05).Univariate regression analysis indicated that hemoglobin(OR 1.025,95%CI 1.007-1.043,P=0.007)and urea(OR 0.897,95%CI 0.791-1.108,P=0.091)were associated with CMD.Multivariate logistic regression further confirmed that elevated hemoglobin concentration was an independent predictor of CMD after PCI in diabetic patients with NSTE-ACS and multivessel disease(OR 1.026,95%CI 1.007-1.045,P=0.006).According to the Youden index of the receiver operating characteristics curve,the optimal cutoff value for diagnosing hemoglobin content is 131 g/L(Youden Index=0.238,sensitivity 69.4%,specificity 54.4%).Conclusions Elevated hemoglobin concentration is an independent risk factor for CMD after PCI in diabetic patients with NSTE-ACS and multivessel disease,potentially linked to hyper-viscous blood-induced oxidative stress and endothelial injury.It is recommended to intensify postoperative microcirculatory monitoring in patients with preoperative hemoglobin≥131 g/L and to explore hemorheological intervention strategies.

Objective:To investigate and analyze basic status of radiotherapy units in Hebei Province in 2024.Methods:Led by the Fourth Hospital of Hebei Medical University, the Radiation Oncology Branch of the Hebei Medical Association, and the Radiation Oncology Expert Committee of the Hebei Society of Clinical Oncology, a province-wide survey was conducted using structured questionnaires. The survey covered key aspects such as basic information of radiotherapy institutions, personnel allocation, equipment configuration, and implementation of radiotherapy techniques. Collected data were summarized and descriptively analyzed comparing with a 2013 survey of radiotherapy in Hebei Province.Results:All 158 radiotherapy institutions across Hebei Province participated in the survey. A total of 2273 radiotherapy professionals were reported, including 1317 radiation oncologists (57.94%), 332 medical physicists (14.61%), 71 radiotherapy engineers (3.12%), and 553 radiotherapy technologists (24.33%). The number of radiotherapy devices significantly increased from 121 in 2013 to 237 in 2024, including 68 domestic radiotherapy equipment. The current inventory includes 195 medical linear accelerators (2.61 units per million population), 2 cobalt-60 units, 27 afterloading machines, 9 tomotherapy (TOMO) systems, 3 CyberKnife units, and 1 proton therapy system. Three-dimensional conformal radiotherapy and stati intensity-modulated radiotherapy have been widely adopted across the province, while advanced techniques such as volumetric-modulated arc therapy, stereotactic body radiotherapy, and respiration-gated technology, and respiratory gating are gradually being implemented.Conclusions:In recent years, the configuration of radiotherapy personnel in Hebei Province has become more balanced, and the availability of precision radiotherapy equipment has significantly improved. There is a growing trend in the adoption of domestically manufactured radiotherapy equipment, marking substantial progress in the development of radiation oncology services in the region.

Objective To investigate the underlying mechanisms of the effect of Fufang Changtai Decoction(FFCT)in inhibiting colorectal cancer(CRC)through the ferroptosis pathway using network pharmacology combined with experimental validation.Methods The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and Swiss Target Prediction databases were employed for the systematic screening of potent active ingredients and therapeutic targets of FFCT.In addition,the identification of CRC-associated genes and ferroptosis-related genes(FRGs)was accomplished using the Gene Cards and FerrDb databases,respectively.Venn diagrams,coupled with Cytoscape software,facilitated the comprehensive analysis of key FRGs involved in FFCT's intervention in CRC by mapping the TCM compound-therapeutic target network.Transmission electron microscopy was used to examine the mitochondrial ultrastructure of SW480 and HCT116,2 Human CRC cell lines,after treatment with FFCT-containing serum.Intracellular reactive oxygen species(ROS)levels were measured using a ROS detection kit.To assess the role of ferroptosis,ferroptosis inhibitor liproxstatin-1(Lip-1)was co-administered with FFCT-containing serum.The effects on cancer cell viability and proliferation were evaluated using CCK-8 and colony formation assays.Key molecular targets involved in the regulatory effects of FFCT on the expression of FRGs were further analyzed using PCR Array and Western blot.The findings were then validated with human CRC tissue microarrays.Results A total of 103 active ingredients of FFCT,739 therapeutic targets,9 101 disease-related genes,and 564 FRGs were identified.Venn diagram analysis identified 81 FRGs associated with FFCT intervention.Network analysis revealed that NQO1,TP53,and PTGS2 served as hub nodes in the regulatory network.Findings from the in vitro experiments showed that FFCT induced ferroptosis changes,including mitochondrial condensation,membrane thickening,and cristae reduction,in SW480 and HCT116 cells.FFCT treatment significantly increased intracellular ROS levels in a dose-dependent manner(P<0.05)and reduced cancer cell viability and proliferative capacity(P<0.01).These inhibitory effects were partially reversed by Lip-1,suggesting that FFCT's antitumor activity was closely associated with the ferroptosis pathway.PCR Array and Western blot analyses further confirmed that FFCT significantly downregulated NQO1 mRNA and protein expression in cancer cells(P<0.001),which was consistent with network pharmacology predictions.Immunofluorescence analysis of clinical CRC tissue microarrays revealed that NQO1 expression was significantly higher in tumor tissues than in adjacent non-tumor tissues(P<0.001).Conclusion FFCT may induce intracellular ferroptosis by downregulating the oncogenic gene NQO1,thereby exerting anti-CRC effects.

Objective:To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness.Methods:CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021.Results:A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%.Conclusion:Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.
