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.

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.

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.

ObjectiveTo observe the effects of Coptidis Rhizoma-Fermentum Rubrum on non-alcoholic fatty liver disease （NAFLD） in mice and explore its possible mechanisms. MethodSixty male SPF C57BL/6J mice were randomly divided into six groups： control group， model group， low-， medium-， and high-dose Coptidis Rhizoma-Fermentum Rubrum group （0.75， 1.5， 3 g·kg^-1）， and metformin group （0.075 g·kg^-1）， with 10 mice in each group. NAFLD mouse models were induced by high-fat diet feeding for 24 weeks. The low， medium， and high-dose Coptidis Rhizoma-Fermentum Rubrum groups were administered corresponding doses of Coptidis Rhizoma-Fermentum Rubrum by gavage， while the control and model groups received an equivalent amount of saline for four weeks. Serum total cholesterol （TC）， triglycerides （TG）， free fatty acids （FFA）， and liver function markers including alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were measured using an automatic biochemical analyzer. Hematoxylin-eosin （HE） and oil red O staining were used to detect liver lipid deposition， and Prussian blue staining was used to measure liver ferrous ion levels. Western blot was performed to detect the expression of key proteins in the nuclear factor erythroid-2-related factor 2 （Nrf2）-glutathione peroxidase 4 （GPX4） axis. ResultAfter 24 weeks of high-fat feeding， compared with the control group， the model group showed significant increases in body weight， liver weight and liver index， and serum lipid levels （P<0.01）， as well as substantial hepatic lipid deposition with marked steatosis. Compared with the model group， Coptidis Rhizoma-Fermentum Rubrum intervention reduced body weight （P<0.01）， liver weight and liver index （P<0.01）， and serum lipid levels （P<0.05， P<0.01）， improved liver function （P<0.01）， and decreased hepatic lipid deposition， with the low-dose Coptidis Rhizoma-Fermentum Rubrum group showing the best effect. Western blot results showed that compared with those in the control group， the expression levels of Nrf2， heme oxygenase-1 （HO-1）， kelch-like ECH-associated protein 1（Keap1）， and GPX4 proteins in the model group were decreased （P<0.05， P<0.01）. Compared with the model group， Coptidis Rhizoma-Fermentum Rubrum increased the expression levels of these proteins （P<0.05， P<0.01）. ConclusionCoptidis Rhizoma-Fermentum Rubrum can alleviate fatty liver in mice， improve liver function， and reduce hepatic lipid deposition， possibly by regulating the Nrf2/GPX4 ferroptosis axis.

The health effects associated with environmental pollutants remain one of the major public health issues at present. The research method focusing on the population as the research subjects is limited by reliable cohorts, and the research method targeting individual molecules cannot fully reflect the biological health effects under environmental pollutant stress. Using high-throughput multi-omics, machine learning, and epigenetic detection to conduct targeted research and joint analysis on cells, organoids, organs, animals, and humans in different biological dimensions will help provide data support for the study of potential targets and biological effects of environmental pollutants, providing a theoretical basis for the risk assessment and safety evaluation of environmental pollutants.

Objective To investigate the changes and clinical significance of serum 25-hydroxyvitamin D3[25(OH)D3],blood calcium and bone metabolism indexes in menopausal women with benign paroxysmal positional vertigo(BPPV).Methods A total of 103 menopausal BPPV patients from Hangzhou Ninth People's Hospital from August 2020 to August 2021 were enrolled into BPPV group.According to the one-year recurrence situation,they were divided into recurrence group(n=18)and non-recurrence group(n=85).A total of 50 healthy menopausal women during the same period were enrolled as control group.The clinical data,serum 25(OH)D3,calcium and bone metabolism indexes[procollagen typeⅠN-terminal propeptide(PINP),N-terminal midfragment of osteocalcin(N-MID),β-isomerised C-terminal telopeptide of collagen typeⅠ(β-CTX),bone alkaline phosphatase(BALP)]were collected.Logistic regression model was constructed to analyze the risk factors of BPPV in menopausal women.The predictive value of related indexes for BPPV recurrence was analyzed by receiver operating characteristic curves.Results The serum 25(OH)D3 level in BPPV group was significantly lower than that in control group(P<0.05),and the proportion of long-term irregular diet,PINP,N-MID and BALP levels were significantly higher than those in control group(P<0.05).Multivariate Logistic regression analysis showed that low 25(OH)D3,high PINP,high N-MID and high BALP were all risk factors for BPPV in menopausal women(P<0.05).The 25(OH)D3 level in recurrence group was significantly lower than that in non-recurrence group(P<0.05),and the PINP,N-MID and BALP levels were significantly higher than those in non-recurrence group(P<0.05).The area under the curve(AUC)of 25(OH)D3,PINP,N-MID,BALP and the four combined predictions for BPPV recurrence were 0.833,0.654,0.697,0.782 and 0.910,respectively,and the AUC of the four combined predictions was the largest.The sensitivity and specificity were 98.97%and 70.62%,respectively.Conclusion There is no significant change in level of serum calcium in menopausal women with BPPV.Decreased serum 25(OH)D3 and increased PINP,N-MID and BALP are risk factors of BPPV,which can be applied to predict BPPV recurrence.

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.
