OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors（SGLT-2i） in patients with heart failure with preserved ejection fraction（HFpEF） in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics， comorbidities， and differences in drug treatment were compared between the two groups. Based on univariate analysis， multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF， followed by further stratified analysis. RESULTS Among 358 HFpEF patients， the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR＝9.063，95%CI（4.924-16.679） ] ， atrial fibrillation [OR＝3.135，95%CI（1.590-6.178） ] ， coronary artery heart disease [OR＝1.888，95%CI（1.072-3.327） ] and the use of loop diuretics [OR＝3.822， 95%CI （1.588-9.200） ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF （ P ＜0.05）. The results of the stratified descriptive analysis were consistent with those of the multivariate analysis， showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM，atrial fibrillation， coronary artery heart disease， and those receiving loop diuretics （ P ＜0.05）； whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function （ P ＞0.05）. CONCLUSIONS In the real-world clinical practice， the utilization of SGLT-2i in patients with HFpEF remains suboptimal， and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes， atrial fibrillation， coronary artery heart disease， and the use of loop diuretics.

AIM:To analyze the efficacy of modified Zhujing formula combined with intravitreal ranibizumab(IVR)injection in the treatment of wet age-related macular degeneration(wARMD).METHODS: A prospective study was conducted on wARMD patients at the Ophthalmology Department of Yulin Hospital of Traditional Chinese Medicine from September 2022 to October 2024. The study subjects were divided into the experimental group and the control group according to the random number table method. The control group received IVR treatment, while the experimental group was treated with modified Zhujing formula in addition to IVR injection. The clinical efficacy, TCM symptom scores, central retinal thickness(CRT), best corrected visual acuity(BCVA), macular hemorrhage area, choroidal neovascularization area(CNV), ocular hemodynamic parameters [resistance index(RI), maximum diastolic blood flow(EDV), maximum systolic blood flow(PSV)], and 1-year recurrence rate were compared between the two groups.RESULTS: This study included 60 eyes from 60 wARMD patients. Among them, the control group consisted of 30 patients and 30 eyes, while the experimental group consisted of 30 patients and 30 eyes. The age of the control group was 67.52±3.12 y, with 17 males and 13 females. The age of the experimental group was 67.62±3.04 y, with 18 males and 12 females.The clinical efficacy of the experimental group(97%)was higher than that of the control group(73%)(P<0.05). After treatment, the scores of blurred vision, soreness and weakness of the waist and knees, restlessness and insomnia, dizziness and tinnitus in the experimental group were all lower than those in the control group(all P<0.05); the EDV and PSV in the experimental group were both higher than those in the control group(both P<0.05); the BCVA, CRT, macular hemorrhage area, CNV and RI of the experimental group were all lower than those of the control group(all P<0.05), and the 1-year recurrence rate in the experimental group(3%)was lower than that in the control group(27%)(P<0.05). CONCLUSION:The combined use of modified Zhujing formula and IVR can effectively alleviate symptoms such as blurred vision and retinal hemorrhage in wARMD patients, improve vision and ocular hemodynamic conditions, and reduce the recurrence rate. This suggests that there may be a synergistic enhancing effect.

With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To evaluate the dynamic changes in fibrinolytic states after initial resuscitation in severe trauma patients, and to analyze the relationship between the changes and clinical outcomes.Methods:A prospective cohort study was conducted on severe trauma patients admitted to the trauma center in Taicang Hospital, affiliated with Soochow University, from July 2021 to December 2022. Resuscitation treatments, including tranexamic acid (TXA), were administered. Thromboelastography was performed at three intervals: upon admission, 1 hour and 8 hours after initial resuscitation. Fibrinolytic states were categorized into three phenotypes based on clot lysis at 30 minutes: fibrinolysis shutdown (SD), physiologic fibrinolysis (PY), and hyperfibrinolysis (HF). The primary outcomes included all-cause mortality at 24 hours and 28 days. Multivariate logistic regression was used to analyze the association between early fibrinolytic changes and clinical outcomes.Results:A total of 132 patients with severe trauma were included. Upon admission, fibrinolytic phenotypes were distributed as follows: SD in 61 patients (46.2%), PY in 59 patients (44.7%), and HF in 12 patients (9.1%). After resuscitation with TXA and other interventions, SD and PY remained predominant, whereas HF further decreased. Compared with the SD and PY groups, the HF group had significantly higher 24-hour mortality (25.0% vs. 3.3% vs. 3.4%, P<0.05) and 28-day mortality (58.3% vs. 32.8% vs. 11.9%, P<0.05), with massive hemorrhage being the primary cause of death. Among the non-HF groups, 28-day mortality was significantly higher in the SD group than in the PY group (32.8% vs. 11.9%, P<0.05), with traumatic brain injury as the leading cause of death. After the exclusion of 12 HF patients, multivariate logistic regression showed that after adjusting for age, Glasgow Coma Scale score ≤ 8, prothrombin time, and 24-hour crystalloid infusion volume, identified persistent SD was a risk factor for 28-day mortality in severe trauma patients, compared with sustained PY status ( OR=7.009, 95% CI: 1.141-43.079, P=0.036). Conclusions:In patients with severe trauma, SD and PY are the predominant fibrinolysis phenotypes after initial and early resuscitation. Persistent SD following resuscitation is significantly associated with an increased risk of 28-day mortality.

Objective To investigate the clinical characteristics,treatment responses,and prognosis of patients with idiopathic multicentric Castleman disease(iMCD)complicated by autoimmune hemolytic anemia(AIHA). Methods The patients diagnosed with iMCD in Peking Union Medical College Hospital from January 2010 to December 2023 and having complete baseline blood routine data were retrospectively enrolled in the study.The iMCD patients were further assigned into AIHA and non-AIHA groups based on baseline laboratory examinations,and the clinical characteristics and prognosis were compared between the two groups. Results A total of 341 patients with iMCD were enrolled in this study,including 277(81.2%)exhibiting anemia at baseline.Five(1.8%)patients were identified as having iMCD-AIHA,all of whom were iMCD-not otherwise specified type complicated by warm antibody-type AIHA,and two of them were simultaneously diagnosed with Evans syndrome.The timing relationship between the first onset of AIHA and iMCD diagnosis varied,with 2 patients experiencing their first hemolytic episode prior to the diagnosis of iMCD.In terms of treatment,the therapy targeting iMCD was effective in alleviating AIHA.The AIHA group had a poorer prognosis(HR=4.61,95% CI=1.08-19.80,P=0.040)and a lower 5-year survival rate(90% vs.60%,P=0.024)than the non-AIHA group.Conclusions iMCD-AIHA is clinically rare,and AIHA can occur at different stages of iMCD.Although the primary treatment principle remains targeting iMCD,great attention should be paid to the exacerbation of immune dysfunction caused by AIHA and the possible adverse prognosis it may bring.
