Traditional Chinese medicine （TCM） therapy has unique clinical advantages in the treatment of atrial fibrillation， mainly reflected in five aspects， improving quality of life， enabling early diagnosis and treatment， promoting cardiac rehabilitation， making up for the limitations of Western medicine， and improving the success rate of catheter ablation. However， there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation， it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys， expert consensus， and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized， and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews， patient interviews， and other methods. Additionally， clinical research design， implementation， and data management should be improved. By leveraging modern information technologies such as artificial intelligence， the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced， ultimately improving the quality of research.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

Objective The objective of this study is to improve the accuracy of automatic identification in complex background herbal slice images.The goal is to achieve accurate recognition of herbal slice images in the presence of complex backgrounds.Methods The experiment was conducted on a collected and organized dataset of Tibetan herbal slice images.The RGB,HOG,and LBP features of the slices were analyzed.An improved HOG algorithm was used to fuse multiple features,and a deep learning network was utilized for image recognition.Results The proposed method of multi-feature fusion combined with deep learning achieved an identification accuracy of 91.68%on 3610 Tibetan herbal slice images with complex backgrounds.Furthermore,the average identification accuracy for 20 common traditional Chinese medicine slices,such as Chuan Beimu,Hawthorn,and Pinellia,reached 98.00%.This method outperformed existing methods for identifying herbal slices in complex backgrounds,indicating its feasibility and wide applicability for the identification of other traditional Chinese herbal medicines.Conclusion The fusion of multiple features effectively captures distinguishing characteristics of herbal slices in complex backgrounds.It exhibits high recognition rates for Tibetan herbal slices with complex and heavily occluded backgrounds,and can be successfully applied to the recognition of natural scene-based traditional Chinese herbal medicines and herbal slices.This approach shows promising prospects for practical applications.

Coronary artery calcifications (CAC) is an independent risk factor for cardiovascular disease (CVD). It has been revealed that this condition can be automatically quantified through computerize tomographic (CT) scan contained in radiotherapy plan for patients with breast cancer, with which, physicians can identify the patients with increased risk of CVD after radiotherapy prematurely and take intervention measures in advance. In this article, the current literature and research progress on the correlation between CAC and cardiotoxicity in patients with breast cancer after radiotherapy were reviewed, expecting to provide a strategy to reduce the CVD risk in patients with breast cancer after radiotherapy.

Objective:To investigate the effects of ubiquitin-specific protease (USP) 7/47 inhibitor (Cat. No. 1247825-37-1) on the proliferation and apoptosis of acute myeloid leukemia (AML) cells with or without internal tandem duplications of the Flt3 gene (Flt3-ITD). Methods:ATP assay was used to detect the effects of 1247825-37-1 on the cell viability of two AML cell lines (MOLM13 and MV4-11) harboring Flt3-ITD mutation and one AML cell line (THP-1) without Flt3-ITD mutation as well as the primary Flt3-ITD-mutant and non-mutant AML cells from patient samples. Flow cytometry was used to detect the apoptosis of AML cell lines treated by different concentrations of 1247825-37-1.Results:Compared with the control group, 1247825-37-1 was able to significantly inhibit the proliferation of MOLM13, MV4-11 and THP-1 cells ( P<0.000 1). Besides, the cell viability of primary AML cells was also inhibited by 1247825-37-1, and a stronger inhibitory effect on non-mutant AML cells was observed. The USP7/USP47 inhibitor 1247825-37-1 could inhibit the proliferation of AML cells in a dose-dependent manner and a low dose (2 or 4 μmol/L) of 1247825-37-1 would be effective. Moreover, 1247825-37-1 was also able to efficiently induce the apoptosis of above AML cell lines in a dose-dependent manner. Conclusions:The USP7/USP47 inhibitor 1247825-37-1 significantly inhibits the proliferation of AML cells with or without Flt3-ITD mutation.

Objective:To analyze the factors affecting delayed chemotherapy in children with Burkitt lymphoma (BL) and their influence on prognosis.Methods:Retrospective cohort study. Clinical data of 591 children aged ≤18 years with BL from May 2017 to December 2022 in China Net Childhood Lymphoma (CNCL) was collected. The patients were treated according to the protocol CNCL-BL-2017. According to the clinical characteristics, therapeutic regimen was divided into group A, group B and group C .Based on whether the total chemotherapy time was delayed, patients were divided into two groups: the delayed chemotherapy group and the non-delayed chemotherapy group. Based on the total delayed time of chemotherapy, patients in group C were divided into non-delayed chemotherapy group, 1-7 days delayed group and more than 7 days delayed group. Relationships between delayed chemotherapy and gender, age, tumor lysis syndrome before chemotherapy, bone marrow involvement, disease group (B/C group), serum lactate dehydrogenase (LDH) > 4 times than normal, grade Ⅲ-Ⅳ myelosuppression after chemotherapy, minimal residual disease in the interim assessment, and severe infection (including severe pneumonia, sepsis, meningitis, chickenpox, etc.) were analyzed. Logistic analysis was used to identify the relevant factors. Kaplan-Meier method was used to analyze the patients' survival information. Log-Rank was used for comparison between groups.Results:Among 591 patients, 504 were males and 87 were females, the follow-up time was 34.8 (18.6,50.1) months. The 3-year overall survival (OS) rate was (92.5±1.1)%,and the 3-year event-free survival (EFS) rate was (90.5±1.2)%. Seventy-three (12.4%) patients were in delayed chemotherapy group and 518 (87.6%) patients were in non-delayed chemotherapy group. The reasons for chemotherapy delay included 72 cases (98.6%) of severe infection, 65 cases (89.0%) of bone marrow suppression, 35 cases (47.9%) of organ dysfunction, 22 cases (30.1%) of tumor lysis syndrome,etc. There were 7 cases of chemotherapy delay in group B, which were seen in COPADM (vincristine+cyclophosphamide+prednisone+daunorubicin+methotrexate+intrathecal injection,4 cases) and CYM (methotrexate+cytarabine+intrathecal injection,3 cases) stages. There were 66 cases of chemotherapy delay in group C, which were common in COPADM (28 cases) and CYVE 1 (low dose cytarabine+high dose cytarabine+etoposide+methotrexate, 12 cases) stages. Multinomial Logistic regression analysis showed that the age over 10 years old ( OR=0.54,95% CI 0.30-0.93), tumor lysis syndrome before chemotherapy ( OR=0.48,95% CI 0.27-0.84) and grade Ⅲ-Ⅳ myelosuppression after chemotherapy ( OR=0.55,95% CI 0.33-0.91)were independent risk factors for chemotherapy delay.The 3-year OS rate and the 3-year EFS rate of children with Burkitt lymphoma in the delayed chemotherapy group were lower than those in the non-delayed chemotherapy group ((79.4±4.9)% vs. (94.2±1.1)%, (80.2±4.8)% vs. (92.0±1.2)%,both P<0.05). The 3-year OS rate of the group C with chemotherapy delay >7 days (42 cases) was lower than that of the group with chemotherapy delay of 1-7 days (22 cases) and the non-delay group (399 cases) ((76.7±6.9)% vs. (81.8±8.2)% vs. (92.7±1.3)%, P=0.002).The 3-year OS rate of the chemotherapy delay group (9 cases) in the COP (vincristine+cyclophosphamide+prednisone) phase was lower than that of the non-chemotherapy delay group (454 cases) ((66.7±15.7)% vs. (91.3±1.4)%, P=0.005). Similarly, the 3-year OS rate of the chemotherapy delay group (11 cases) in the COPADM1 phase was lower than that of the non-chemotherapy delay group (452 cases) ((63.6±14.5)% vs. (91.5±1.3)%, P=0.001). Conclusions:The delayed chemotherapy was related to the age over 10 years old, tumor lysis syndrome before chemotherapy and grade Ⅲ-Ⅳ myelosuppression after chemotherapy in pediatric BL. There is a significant relationship between delayed chemotherapy and prognosis of BL in children.

Objective:To investigate the efficacy and prognostic survival of pembrolizumab combined with apatinib and chemotherapy in the treatment of human epidermal growth factor receptor-2 (HER2)-negative advanced gastric cancer.Methods:Patients with HER2-negative advanced gastric cancer were selected from December 2019 to December 2022 as the study subjects. Forty-five patients who received chemotherapy therapy (fluorouracil+cisplatin) were randomly collected and included in control group, and 52 patients who were treated with pembrolizumab combined with apatinib were randomly selected and enrolled as observation group. The difference in short-term efficacy was compared. The levels of serum tumor markers and immune function (CD3 +, CD4 +, CD8 +, CD4 +/CD8 +) were recorded. The long-term efficacy and adverse reactions of patients were compared. Measurement data conforming to the normal distribution were expressed as xˉ± s, and the mean comparison between groups was performed by independent sample t test. Chi-square test was used to compare the rate or composition ratio among enumeration data. P<0.05 was considered statistically significant. Results:At 6 months after treatment, the disease control rate in observation group was significantly higher than that in control group (78.85% (41/52) vs 57.78% (26/45)) ( χ2=5.01, P=0.025), but there was no statistical significance in objective response rate between groups (36.54% (19/52) vs 24.45% (11/45)) ( χ2=1.65, P=0.199). The levels of pepsinogen I, tissue polypeptide specific antigen, carcinoembryonic antigen, carbohydrate antigen 199 and CD8 + in both groups were reduced after treatment, and the levels were lower in observation group than those in control group ( t=6.06, 6.78, 4.68, 11.21, 3.45, all P<0.001). The levels of CD3 +, CD4 + and CD4 +/CD8 + were enhanced significantly in the two groups, and the observation group had higher levels after treatment ( t values were 2.10, 3.74, and 5.19; P values were 0.028, <0.001, and <0.001). After 1 year of follow-up, the survival rate in observation group with 59.62% (31/52) was significantly higher than 37.78% (17/45) in control group ( χ2=4.60, P=0.032). The progression-free survival time ((10.22±1.62) months vs (8.13±1.57) months, t=6.43, P<0.001) and overall survival time ((11.62±1.84) months vs (9.73±1.71) months, t=5.21, P<0.001) in observation group were significantly longer compared to control group. There were no statistical differences in the incidence rates of bone marrow suppression ( χ2=1.92, P=0.165), hand-foot syndrome ( χ2=3.47, P=0.062), gastrointestinal reaction ( χ2=0.32, P=0.574), hypertension ( χ2=0.94, P=0.333) and proteinuria ( χ2=2.39, P=0.122) between the two groups. Conclusion:Compared with chemotherapy, pembrolizumab combined with apatinib shows good short-term efficacy and long-term efficacy in patients with HER2-negative advanced gastric cancer.

Objective:To explore the risk factors for complications related to internal fixation after Inter-Tan intramedullary nail fixation in the treatment of intertrochanteric fractures in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 314 elderly patients with intertrochanteric fractures admitted to the Seventh Medical Center of the Chinese PLA General Hospital from January 2016 to December 2020, including 100 males and 214 females, aged 60-98 years [(80.2±8.2)years]. All the patients underwent Inter-Tan intramedullary nail fixation. According to the 2018 AO/OTA classification, 103 patients were with stable fractures and 211 with unstable fractures. The patients were further divided into complication groups and non-complication groups according to the presence of the complications during the follow-up. Six patients (5.8%) with stable fractures had the complications including nonunion in 4 and cut-out in 2. Twenty-eight patients (13.3%) with unstable fractures developed the complications, including nonunion in 5, cut-out in 20, cut-through in 1, and broken nails in 2. With the internal fixation-related complications after surgery as dependent variables, and gender, age, complications [hypertension, coronary heart disease, arrhythmia, pulmonary infection, chronic obstructive pulmonary disease (COPD), renal insufficiency, diabetes], bone density, waiting time for surgery, anesthesia method, reduction method, reduction quality, tip-apex distance, head screw displacement and other influencing factors as independent variables, univariate and multivariate Logistic regression analyses were conducted on the patients with stable fractures and unstable fractures separately to screen the independent risk factors of internal fixation-related complications.Results:For the patients with stable fractures, the univariate analysis indicated significant differences in bone density and reduction quality between the complication group and non-complication group ( P<0.05 or 0.01); the multivariate Logistic regression analysis showed that bone density T value ≤-3.0 SD ( OR=33.17, 95% CI 2.40, 457.82, P<0.01) and poor reduction quality ( OR=71.38, 95% CI 3.58, 1 422.02, P<0.01) were significantly correlated with the incidence of the postoperative complications. For the patients with unstable fractures, the univariate analysis indicated significant differences in age, reduction quality, bone density, tip-apex distance, and screw displacement between the complication group and non-complication group ( P<0.05 or 0.01); the multivariate Logistic regression analysis showed that age >80 years ( OR=2.82, 95% CI 1.01, 7.93, P<0.05), bone density T value ≤-3.0 SD ( OR=6.10, 95% CI 2.06, 17.51, P<0.01), poor reduction quality ( OR=12.25, 95% CI 2.90, 51.79, P<0.01), tip-apex distance ≥25 mm ( OR=3.65, 95% CI 1.20, 11.08, P<0.05), and head screw displacement <4 mm ( OR=7.26, 95% CI 2.54, 20.81, P<0.01) were significantly correlated with the postoperative complications. Conclusion:For Inter-Tan intramedullary nail fixation of intertrochanteric fractures in elderly patients, low bone density and poor reduction quality are independent risk factors for the postoperative complications in patients with stable intertrochanteric fractures; old age, low bone density, poor reduction quality, tip-apex distance, and head screw displacement are independent risk factors for the postoperative complications in patients with unstable fractures.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
