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.

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.

Next generation sequencing (NGS) technology is playing an increasingly important role in the diagnosis of genetic diseases. Whole exome sequencing (WES), which targets the coding regions of the genome, has been widely used in the diagnosis of genetic diseases for its low cost and high efficiency. However, compared to conventional methods, the Next Generation Sequencing (NGS) process is intricate, and there is variability in the expertise of data analysts and variant interpreters, which may lead to inconsistencies in the outcomes. To ensure the quality of testing and enhance the diagnostic rate of diseases, this consensus has provided recommendations regarding the laboratory setup, operational procedures, data analysis, result interpretation, and quality control for WES, with an aim to standardize its application in the detection of genetic disorders.

Objective:To evaluate the impact of implementing a regional hierarchical medical management model based on the medical internet of things (medical IoT) on the frequency of emergency department visits and hospitalizations, as well as related medical expenses, in patients with chronic obstructive pulmonary disease (COPD).Methods:This retrospective study included COPD patients enrolled in the regional hierarchical medical management system based on Medical IoT across 21 community health service centers in Songjiang District, Shanghai, between July 2017 and May 2018. Utilizing patient data from the year prior to enrollment as the baseline, changes in the number of emergency visits, hospitalizations, and associated medical costs during the first and second years of management were compared. Changes for patients receiving drug treatment were also analyzed.Results:A total of 973 COPD patients were enrolled. The mean age was 75.2±17.0 years, and 64.34% (626/973) were male. Compared to baseline, all COPD patients in the first year of management showed significant reductions: emergency visits decreased by 33.67%, total emergency costs by 45.60%, hospitalizations by 27.15%, and total hospitalization costs by 25.42%. In the second year, reductions were: emergency visits by 28.08%, total emergency costs by 36.10%, hospitalizations by 35.26%, and total hospitalization costs by 18.13% (all P<0.05). Among patients receiving drug therapy, reductions in the first year were: emergency visits by 39.66%, total emergency costs by 47.54%, hospitalizations by 25.19%, and total hospitalization costs by 28.40%. In the second year, reductions were: emergency visits by 46.98%, total emergency costs by 45.99%, hospitalizations by 41.98%, and total hospitalization costs by 24.94% (all P<0.05). No significant differences were observed before and after management for patients without drug treatment. Conclusion:The implementation of the regional hierarchical medical management model based on Medical IoT significantly reduced the frequency of emergency visits and hospitalizations, as well as related costs, for COPD patients.

Objective:To explore the impacts of different frequencies of orthogonal image-guided verification on set-up error correction and the reference values of planning target volume (PTV) margins in postoperative radiotherapy for breast cancer, in order to provide recommendations of the verification frequency in clinical practice.Methods:A total of 80 breast cancer patients who received postoperative intensity-modulated radiotherapy for breast cancer at the Affiliated Union Hospital of Fujian Medical University from January 2021 to January 2022 were enrolled. Orthogonal image-guided verification was conducted before each radiation treatment to determine initial and residual set-up errors. The error data were statistically analyzed by categorizing patients into groups A, B, C, D, E, and F, based on assumed verification frequencies (daily, every 2, 3, 4, and 5 d, and no correction). The magnitude, distribution, and differences of set-up errors of various groups were analyzed, and the PTV margins were calculated using a reference formula.Results:The collected initial set-up errors of the 80 patients were (3.49±3.43), (2.87±2.88), and (2.75±2.35) mm, in x, y, and z directions, respectively. The residual set-up errors decreased gradually with increasing verification frequency. In the case of daily image-guided verification, the residual set-up errors in x, y, and z directions decreased to (1.63±0.90), (1.63±0.93), and (1.55±0.90)mm, respectively. The reference values of PTV margins calculated under different verification frequencies decreased with an increase in the verification frequency. Under daily verification, the reference values of PTV margins calculated based on set-up errors decreased from initial 6.60, 6.29, and 4.22 mm (without correction) to 1.27, 1.37, and 1.28 mm, respectively. Differences in the reference values under verification frequencies every 3, 4, and 5 d were less than 0.81 mm. Conclusions:Daily image-guided verification (including correction) can effectively reduce set-up errors in image-guided radiotherapy for breast cancer. The set-up errors differ under varying verification frequencies, with a higher frequency corresponding to better correction effects and smaller PTV margins required.

Both the incidence and mortality of primary liver cancer in China rank first globally. Stereotactic body radiotherapy (SBRT) is valued for its ability to significantly enhance the irradiation precision of target volumes while reducing the radiation doses to surrounding normal tissues. Respiratory motion management represents a critical SBRT technology. Meanwhile, abdominal compression has been extensively applied as a critical approach to respiratory motion management thanks to its convenient operation and high applicability. Furthermore, applying abdominal compression to the liver can effectively reduce the extent of motion of the gross target volumes, thus reducing the expanding ranges of the internal target volumes (ITVs). This further contributes to increased radiation dose to target volumes and decreased radiation dose to surrounding normal tissues. Focusing on respiratory motion management for the liver, the application of abdominal compression, improvements in abdominal compression devices, and method for assessing the abdominal compression effects, this study presents a review of advances in research on the application of abdominal compression in SBRT for liver cancer, aiming to provide a valuable reference for clinical practice.

In February 2025, a local cluster outbreak caused by the D8 genotype Measles virus (MV) was first discovered in Henan Province. Epidemiological investigations and laboratory testing were conducted, including the collection of serum and throat swabs for MV IgM antibody and nucleic acid detection, virus isolation and genetic homology analysis. Measures such as close contact tracing, vaccination rate assessment and supplementary immunization activities were implemented, successfully preventing broader community transmission. A total of three cases were reported during the outbreak, including one imported-related adolescent and two secondary local adult cases. All cases presented with typical symptoms such as fever and rash. Both adult cases were complicated by pneumonia, with one case developing into severe pneumonia. MV genotyping showed that the two secondary cases were both the D8 genotype, with the viral sequences being completely homologous to the Kazakhstan strain. Among the close contacts, 98.2% were adults, and 142 individuals received emergency vaccination.

Objective:To evaluate the effects of laser moxibustion(LM)on tumor-related immunity in tumor-bearing mice.Methods:Thirty male C57BL/6 mice were randomized into a control group,a model group,and an LM group,with 10 mice in each group.Mice in the control group did not receive any intervention,and mice in the model group and LM group were injected into the right armpit with 1×107 cells/mL Lewis lung carcinoma cells to induce tumor models.From the first day after the injection,the LM group mice were irradiated with LM at Guanyuan(CV4)and bilateral Zusanli(ST36),5 min each point for a total of 15 min,once daily for 15 consecutive days.From the day of visible tumor formation(i.e.,day 8),mice in the model and LM groups were measured every other day with a vernier caliper to calculate the tumor volume.On day 16 after injection,the serum,lung,spleen,and tumors of the mice were harvested.Hematoxylin-eosin staining was used to observe tumor pulmonary metastasis.Changes in the serum levels of programmed death 1(PD-1)and programmed death-ligand 1(PD-L1)were analyzed by enzyme-linked immunosorbent assay;the abundance of PD-1 and PD-L1 proteins in tumors was determined by Western blotting;and the proportions of lymphocyte subsets and myeloid-derived suppressor cells(MDSCs)in tumors and spleen were determined by flow cytometry.Results:Compared to the model group,the tumor volume of mice in the LM group decreased significantly on days 8 and 10(P<0.05);the lung tissues of the LM group showed no apparent tumor atypia;the proportion of monocytic MDSCs(M-MDSCs)in the tumors of LM group mice decreased(P<0.05);the PD-1 and PD-L1 levels in the serum of mice in the LM group declined with statistically significant variation in the reduction of PD-L1(P<0.01);PD-1 and PD-L1 protein expression in the tumor tissues of mice in the LM group reduced significantly(P<0.01).Conclusion:LM intervention can reduce the expression of PD-1 and PD-L1 in the serum of tumor-bearing mice,decrease the expression of PD-1 and PD-L1 proteins and the proportion of M-MDSCs in tumor tissues.These effects may be one of the mechanisms by which LM slows the early-stage growth of Lewis lung carcinoma tumor in mice.

Objective:To investigate the prevalence status and the clinical characteristics of hepatitis D virus (HDV) among patients chronically infected with hepatitis B virus (HBV) in the Xinjiang region.Methods:A cross-sectional study was conducted. Serum samples from 1 830 patients with chronic HBV infection who visited the Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from December 2022 to October 2023 were collected. All sera were tested for anti-HDV IgG and IgM. Sera positive for anti-HDV IgG or IgM were selected for HDV RNA detection. HDV RNA-positive sera were sequenced to determine the HDV genotype. Age, gender, HBV course, and anti-HBV treatment status were used as scoring items based on the propensity score matching (PSM) method. Chronic HBV patients with negative anti-HDV were matched in a ratio of 1∶1. The clinical characteristics of anti-HDV -positive-patients were analyzed. The t-test was used for comparison between groups of normally distributed continuous data. The Wilcoxon signed-rank test was used for comparison between groups of skewness distribution. The χ2 test was used for comparison between groups of enumeration data. Results:The positive detection rates of anti-HDV IgG, anti-HDV IgM, and HDV RNA in 1 830 cases with chronic HBV infection were 2.24% (41/1 830), 1.09% (20/1 830), and 1.69% (31/1 830), respectively. All HDV RNA-positive patients had HDV genotype 1. Two anti-HDV-positive patients had negative hepatitis B surface antigen (HBsAg). Gender, age, HBV course, and anti-HBV treatment status had no significant difference. The quantification of HBsAg, liver biochemical indexes (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bile acids), the proportion of patients with liver cirrhosis, and alpha-fetoprotein were significantly higher in the anti-HDV-positive group than in those in the anti-HDV-negative group ( P<0.05). Conclusion:The prevalence rate of HDV in chronic HBV-infected patients at a single center in the Xinjiang region was 2.24%, with the primary genotype being 1. Furthermore, overlap infection should be paid attention to because it might aggravate liver damage.
