Background: Gestational diabetes mellitus (GDM) is a metabolic disorder posing significant risks to maternal and infant health, with a lack of effective early screening markers. Therefore, identifying early screening biomarkers for GDM with higher sensitivity and specificity is urgently needed. Methods: High-throughput sequencing was employed to screen for key circular RNAs (circRNAs), which were then evaluated using reverse transcription quantitative polymerase chain reaction. Logistic regression analysis was conducted to examine the relationship between clinical characteristics, circRNA expression, and adverse pregnancy outcomes. The diagnostic accuracy of circRNAs for early and mid-pregnancy GDM was assessed using receiver operating characteristic curves. Pearson correlation analysis was utilized to explore the relationship between circRNA levels and oral glucose tolerance test results. A predictive model for early GDM was established using logistic regression. Results: Significant alterations in circRNA expression profiles were detected in GDM patients, with hsa_circ_0031560 and hsa_ circ_0000793 notably upregulated during the first and second trimesters. These circRNAs were associated with adverse pregnancy outcomes and effectively differentiated GDM patients, with second trimester cohorts achieving an area under the curve (AUC) of 0.836. In first trimester cohorts, these circRNAs identified potential GDM patients with AUCs of 0.832 and 0.765, respectively. The early GDM prediction model achieved an AUC of 0.904, validated in two independent cohorts. Conclusion Hsa_circ_0031560, hsa_circ_0000793, and the developed model serve as biomarkers for early prediction or midterm diagnosis of GDM, offering clinical tools for early GDM screening.

Objective To compare the dosimetric differences in the heart and its substructures between two hybrid plans for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. Methods A total of 46 patients with early-stage left-sided breast cancer who underwent hypofractionated whole-breast radiotherapy were randomly selected. Two hybrid radiotherapy plans were used, including hybrid intensity-modulated radiotherapy (H_IMRT) and hybrid volumetric-modulated arc therapy (H_VMAT). The heart and its substructures were contoured, including left anterior descending (LAD), left ventricle (LV), right coronary artery (RCA), and right ventricle (RV). The heart and substructure doses, as well as monitor units, were compared between H_IMRT and H_VMAT. Results Both hybrid plans met the clinical requirements. H_IMRT significantly outperformed H_VMAT for the heart (V₁₀, V₃₀, and D_mean), LAD (V₃₀, V₄₀, D_max and D_mean), LV (V₁₀, V₂₀ and D_mean), RCA (D_max, D_mean), and RV (V₅, V₁₀, D_mean) (P < 0.001). Additionally, H_IMRT was significantly superior to H_VMAT for heart V₅, LAD V₂₀, and RV V₂₀ (P = 0.005, 0.035 and 0.037). For LAD (V₁₅, V₄₀) and LV (V₅, V₂₅), H_IMRT was slightly better than H_VMAT, and the difference was not statistically significant. Conclusion Both H_IMRT and H_VMAT hybrid radiotherapy plans are suitable for hypofractionated whole-breast radiotherapy after breast-conserving surgery in patients with early-stage left-sided breast cancer. H_IMRT is slightly better than H_VMAT in dose sparing for the heart and its substructures.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Cancer is a major global health issue. Effective therapeutic strategies can prolong patients’ survival and reduce the costs of treatment. Drug repurposing, which identifies new therapeutic uses for approved drugs, is a promising approach with the advantages of reducing research costs, shortening development time, and increasing efficiency and safety. Disulfiram (DSF), a Food and Drug Administration (FDA)-approved drug used to treat chronic alcoholism, has a great potential as an anticancer drug by targeting diverse human malignancies. Several studies show the antitumor effects of DSF, particularly the combination of DSF and copper (DSF/Cu), on a wide range of cancers such as glioblastoma (GBM), breast cancer, liver cancer, pancreatic cancer, and melanoma. In this review, we summarize the antitumor mechanisms of DSF/Cu, including induction of intracellular reactive oxygen species (ROS) and various cell death signaling pathways, and inhibition of proteasome activity, as well as inhibition of nuclear factor-kappa B (NF-κB) signaling. Furthermore, we highlight the ability of DSF/Cu to target cancer stem cells (CSCs), which provides a new approach to prevent tumor recurrence and metastasis. Strikingly, DSF/Cu inhibits several molecular targets associated with drug resistance, and therefore it is becoming a novel option to increase the sensitivity of chemo-resistant and radio-resistant patients. Studies of DSF/Cu may shed light on its improved application to clinical tumor treatment.

Objective:To evaluate the feasibility of using a visual positioning system for both motion phantom and clinical quality control.Methods:A phantom experiment was conducted using the Dynamic Thorax Phantom from CIRS. Different ranges of motion were simulated to assess the discrepancies between camera-recorded positions and actual movements. Visual markers were also attached to the treatment bed and the collimator head, and their movements were simulated as part of the experiment. The experiment was repeated for three times. Discrepancies between system measurements and manual measurements were recorded and analyzed to assess the accuracy and reliability of the system.Results:In the motion phantom test, the deviation between the actual motion distance of the phantom and the system's recorded measurement was (0.18±0.07) mm. For linear motion analysis along the X, Y, and Z axes on the treatment table, the measurement errors were (0.14±0.08) mm, (0.15±0.09) mm, and (0.16±0.08) mm, respectively. Additionally, the measurement error in the rotational direction of the treatment couch was 0.18°±0.09°. For the rotational direction of the collimator head, the measurement error was 0.11°±0.02°. Conclusion:The system demonstrates good accuracy and stability, and has potential clinical application value.

BACKGROUND:At present,the use of a locking bone plate combined with steel wire or steel cable for the treatment of periprosthetic femoral fracture often adopts monocortical fixation,which is not stable and the proximal end of the bone cannot be achieved anatomically fitted by plate.The customized anatomical plate system can effectively solve this problem. OBJECTIVE:To explore the biomechanical strength of a customized anatomical plate system in fixation of Vancouver BI periprosthetic femoral fracture. METHODS:CT thin layer scanning data of normal femurs of 1 006 cases were selected and input into the MIMICS 21.0 software to establish the three-dimensional reconstruction model of the femur,which was set as the three-dimensional reconstruction group.56 complete human femoral specimens were selected as the femoral specimen group.The measured results of the two groups for femoral anatomical appearance were compared.If there was no significant difference between the two groups,the approximate appearance of a customized anatomical plate system was designed based on the measurement results in MIMICS 21.0 software and NX11.0 software.The customized anatomical plate system was designed and prepared according to the above measurement results.Eight pairs of frozen human femurs were selected to make Vancouver BI periprosthetic femoral fracture,which of the left were thin layer scanned by dual-source CT to obtain data.The data were transferred to determine the customized anatomical plate system model by the above design software.Eight sets of customized anatomical plate systems were ultimately produced,relying on the instrument company.The eight pairs of models were numbered 1-8.The left side was fixed with the customized anatomical plate system(customized anatomical plate system group);the right side was fixed with a metal locking plate system-large locking plate(claw plate group).L1-L4 and R1-R4 were subjected to vertical short-cycle loading test and vertical loading test.L5-L8 and R5-R8 were subjected to horizontal short-cycle loading test and four-point bending test.The vertical loading test and four-point bending test were used to collect bending load,bending displacement,and bending strain.Two short cycle loading tests were used to collect strain displacement to compare the maximum load,maximum displacement,bending stiffness,and short-period displacement resistance of the two kinds of bone plates. RESULTS AND CONCLUSION:(1)There were no significant differences in all indexes between the three-dimensional reconstruction group and the femoral specimen group(P>0.05).Individual customized anatomical plate system was designed based on the measurement results combined with digital software.(2)In the vertical loading test,the maximum load was higher(P=0.015),the maximum bending displacement was smaller(P=0.014),and the bending stiffness was higher(P=0.005)in the customized anatomical plate system group compared with the claw plate group.(3)In the four-point bending test,the maximum load was higher(P=0.023),the bending stiffness was higher(P=0.005),and the maximum bending displacement was not significant(P=0.216>0.05)in the customized anatomical plate system group compared with the claw plate group.(4)In the vertical short-cycle loading test,the average level of bending displacement in the customized anatomical plate system group(0.23±0.10 mm)was significantly lower than that in the claw plate group(0.44±0.02 mm)(P<0.05).(5)There was no significant difference in the average level of bending displacement between the two groups in the horizontal short cycle loading test(P>0.05).(6)It is concluded that the customized anatomical plate system has personalized anatomical characteristics,and the fixation of Vancouver BI periprosthetic femoral fracture is more stable,which has certain significance for clinical treatment.
