Computational analysis can accurately detect drug-gene interactions (DGIs) cost-effectively. However, transductive learning models are the hotspot to reveal the promising performance for unknown DGIs (both drugs and genes are present in the training model), without special attention to the unseen DGIs (both drugs and genes are absent in the training model). In view of this, this study, for the first time, proposed an inductive learning-based model for the precise identification of unseen DGIs. In our study, by integrating disease nodes to avoid data sparsity, a multi-relational drug-disease-gene (DDG) graph was constructed to achieve effective fusion of data on DDG intro-relationships and inter-actions. Following the extraction of graph features by utilizing graph embedding algorithms, our next step was the retrieval of the attributes of individual gene and drug nodes. In this way, a hybrid feature characterization was represented by integrating graph features and node attributes. Machine learning (ML) models were built, enabling the fulfillment of transductive predictions of unknown DGIs. To realize inductive learning, this study generated an innovative idea of transforming known node vectors derived from the DDG graph into representations of unseen nodes using node similarities as weights, enabling inductive predictions for the unseen DGIs. Consequently, the final model was superior to existing models, with significant improvement in predicting both external unknown and unseen DGIs. The practical feasibility of our model was further confirmed through case study and molecular docking. In summary, this study establishes an efficient data-driven approach through the proposed modeling, suggesting its value as a promising tool for accelerating drug discovery and repurposing.

Objective:To evaluate the short-and medium-term therapeutic efficacy of shockwave balloon therapy for TASCⅡ C/D femoropopliteal artery atherosclerosis obliteration.Methods:This retrospective cohort study included 25 patients who received shockwave balloon therapy in five vascular centers from August 2022 to June 2023. All patients were diagnosed with TASC Ⅱ C/D femoropopliteal arteriosclerosis obliterans (13 cases of type C and 12 cases of type D), and underwent intravascular shock wave lithotripsy (IVL) to treat calcified lesions. The immediate effectiveness (residual stenosis<30% and no flow-limiting dissection), safety (whether there were adverse vascular events during the operation) and the rate of salvage stent implantation were recorded. The observation indexes of patients before operation, early postoperative period (immediately after operation or before discharge) and postoperative follow-up period (3, 6, 12 months after operation) were collected. The observation indexes included ankle-brachial index (ABI), Rutherford classification, and minimum lumen diameter (MLD). Repeated measures ANOVA was used to evaluate the changes of observation indexes in the early postoperative and follow-up stages compared with those before operation; Kaplan-Meier survival analysis was used to evaluate the one-stage patency rate at follow-up and the target lesion revascularization rate free from clinical drive.Results:The immediate effectiveness of surgery was 100% in all patients, with no vascular related adverse events occurred, and no remedial stent implantation was performed. The ABI, Rutherford grade and MLD of the patients in the early postoperative period and each follow-up stage were improved compared with those before operation, with statistically significant differences ( P<0.05). Kaplan-Meier survival analysis showed that the primary patency rate at 12 months after surgery was 0.78 (95% CI 0.64-0.84), and the revascularization rate of target lesions free from clinical drive was 0.87 (95% CI 0.85-0.95). Conclusion:Shockwave balloon therapy for complex calcified femoropopliteal artery lesions is safe and reliable, with satisfactory short-and medium-term efficacy.

Objective To investigate the clinical characteristics and related risk factors of severe Mycoplasmal pneumoniae pneumonia(SMPP)in children.Methods Analysis of clinical data of 240 children with Mycoplasmal pneumoniae pneumonia admitted to Guangxi Hospital Division of the First Affiliated Hospital,Sun Yat-sen University from October 2023 to March 2024.According to the severity of the disease,they were divided into SMPP group and general Mycoplasmal pneumoniae pneumonia(GMPP)group,multivariate Logistic regression analysis was used to analyze the risk factors related to the occurrence of SMPP.The receiver operating characteristic(ROC)curve was plotted to analyze the predictive value of each independent risk factor of SMPP.Results Compared the data during hospitalisation between GMPP group and SMPP group,the SMPP group had longer fever course,hospitalization time,azithromycin treatment time,and glucocorticoid use time(P＜0.05).The proportion of patients with unilateral lung lesions and large patchy shadows in SMPP group were significantly higher than those in GMPP group(P＜0.05).The levels of C-reactive protein,interleukin(IL)-6,and D-dimer in SMPP group were significantly higher than those in GMPP group,while the peripheral blood lymphocyte count was significantly lower than that in GMPP group(P＜0.05).The results of multiple Logistic regression analysis showed that the duration of fever,D-dimer,IL-6,and large patchy shadows in the lungs were independent risk factors for SMPP.The ROC curve results showed that fever duration ≥ 6.5 days,D-dimer≥0.495mg/L,IL-6≥11.05pg/ml,and large patchy shadows in the lungs had good application value in distinguishing SMPP and GMPP children.Conclusion Prolonged fever duration(≥6.5 days),significantly elevated levels of D-dimer and IL-6,and large patchy shadows in the lungs are the main clinical features of children with SMPP,which may be independent risk factors for predicting SMPP.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To evaluate the therapeutic effectiveness of adult patients with Kashin-Beck disease (KBD) in Gansu Province, and provide guidance for rational and effective treatment of KBD patients.Methods:The KBD patients who participated in the "2021 Basic Public Health Service Subsidy Key Endemic Disease Prevention and Control Project" in Gansu Province were selected as the research subjects. Gender, age, clinical grading characteristics, and treatment plan selection of all subjects were analyzed, and the treatment effectiveness of KBD patients in different regions was evaluated.Results:A total of 6 711 KBD patients were included in the treatment program, including 3 139 males (46.8%) and 3 572 females (53.2%), 3 157 cases (47.0%) of patients aged 60 and 3 554 cases (53.0%) over 60 years old. There were 3 921, 2 166, and 624 patients with grades Ⅰ, Ⅱ, and Ⅲ, respectively, accounting for 58.4%, 32.3%, and 9.3%, respectively. The gender, age composition, and clinical grading among KBD patients included in different regions were compared, and the differences were statistically significant (χ 2 = 194.34, 47.44, 408.61, P < 0.001). In the distribution of treatment schemes, the number of patients who selected "drug treatment", "drug treatment combined with physical therapy", "drug treatment combined with acupuncture and moxibustion/massage", "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy", and "other treatment schemes" were 4 084 (60.9%), 726 (10.8%), 672 (10.0%), 443 (6.6%), and 786 (11.7%), respectively. The distribution of treatment plans in different regions was compared, and the difference was statistically significant (χ 2 = 1 088.38, P < 0.001). The total effective rate of KBD patients was 84.5% (5 668/6 711). The total effective rates of KBD patients with different clinical grades were ranked from high to low as grade Ⅲ (87.3%, 545/624), grade Ⅱ (86.4%, 1 871/2 166), and grade Ⅰ (82.9%, 3 252/3 921). The total effective rate of KBD patients with different treatment schemes from high to low was "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" (91.0%, 403/443), "drug treatment combined with physical therapy" (87.1%, 632/726), "drug treatment" (86.7%, 3 539/4 084), "drug treatment combined with acupuncture and moxibustion/massage" (82.3%, 553/672), and "other treatment schemes" (68.8%, 541/786). The total effective rate of KBD patients in different regions, from high to low, was as follows: Linxia Hui Autonomous Prefecture (100%, 144/144), Qingyang City (88.7%, 3 562/4 017), Pingliang City (85.0%, 1 327/1 562), Gannan Tibetan Autonomous Prefecture (83.9%, 78/93), Dingxi City (70.9%, 151/213), Tianshui City (62.5%, 125/200), and Longnan City (58.3%, 281/482). The total effective rate of KBD patients in different clinical grades, treatment schemes, and regions was compared, and the differences were statistically significant (χ 2 = 16.95, 181.72, 435.80, P < 0.001). Conclusions:The overall effective rate of treatment for KBD patients in Gansu Province is relatively high, but there are significant differences in therapeutic outcomes among cities (prefectures); it is related to the treatment scheme and the clinical grading of patients. The scheme of "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" has better efficacy.

Matrix Gla protein (MGP) is a vitamin K-dependent protein secreted by chondrocytes and vascular smooth muscle cells. It is mainly distributed in cartilage, bone marrow, and arterial walls, and participates in osteogenic differentiation and vascular calcification processes in vascular smooth muscle. Previous studies have suggested that MGP only has inhibitory effects on physiological and ectopic calcification. A new study has found that MGP is highly expressed in various tumor tissues, but the relationship between its expression level and the malignant biological behavior of tumors is not completely consistent in different tumors. The differential expression of MGP may be a result of tumor heterogeneity. This article reviews the research progress of MGP in multi-system malignant tumors, in order to provide new ideas for the diagnosis and treatment of clinical malignant tumors.
