With the development of society and changes in people's lifestyles, diabetes mellitus (DM) has become a major risk factor threatening human health, with its incidence rate increasing year by year. Based on the theory of "excessive fire consumes qi while mild fire generates qi", combined with the pathological mechanism and symptom characteristics of DM complicated with heart failure (HF), it is considered that deficiency and insufficiency of "less fire" and excessive "strong fire" consume qi are the fundamental pathogenesis of the occurrence and development of the two diseases. Phlegm, dampness, blood stasis and water are all from this, which further aggravates the disease. The basic treatment principle of "tonifying qi, activating yang, supporting Shao fire, clearing heat, detoxifying and strengthening fire" was proposed. Combined with the different emphasis of patients' syndromes, the treatment methods of promoting blood circulation and removing blood stasis, diuresis and phlegm were supplemented, in order to improve the clinical symptoms of patients and improve the survival rate.

Purpose: The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs). Materials and Methods: Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients. Results: A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804. Conclusion USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective To compare the efficacy and safety of different cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) for the treatment of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) advanced or metastatic breast cancer. Methods Randomized controlled trials (RCTs) on CDK4/6i for the treatment of HR+/HER2− metastatic or advanced breast cancer were retrieved from databases including PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP, and SinoMed, with the search period ranging from database inception to August 2023. Bayesian network meta-analysis was conducted using R 4.2.0 software. Results A total of 18 RCTs from 25 articles, involving 8 031 patients and 11 treatment regimens, were included. There was no significant difference in progression-free survival (PFS) or overall survival (OS) among different CDK4/6i+ET combinations. The highest cumulative probability for PFS was observed with dalpiciclib (DAL)+fulvestrant (FUL), while ribociclib (RIB)+FUL ranked first for OS. In terms of efficacy, abemaciclib (ABE)+aromatase inhibitors (AI) and ABE+FUL ranked first in objective response rate and clinical benefit rate, respectively. Regarding safety, statistically significant difference in grade 3-4 adverse events was observed among certain types of CDK4/6i (P<0.05). Conclusion Current evidence suggests that CDK4/6i+ET is superior to ET alone for the treatment of HR+/HER2− advanced/metastatic breast cancer. Different CDK4/6i+ET combinations demonstrate comparable or similar efficacy; however, the incidence of adverse reactions is higher with combination therapy. Treatment regimens should be selected based on individual conditions.

Objective:To investigate the impact of different target sites, number of treatments, and age on setup errors in dual-isocenter radiotherapy for breast cancer, and to provide a basis for planning target volume (PTV) margin expansion.Methods:A retrospective analysis was conducted on data from 15 patients with left-sided breast cancer who underwent dual-isocenter breath-hold radiotherapy in the Department of Radiotherapy Oncology at the Second Hospital of Hebei Medical University from May 2021 to May 2023. Setup errors were acquired using a Varian TrueBeam STX linear accelerator. Patients were grouped by target site (supraclavicular/chest wall), treatment phase (early/late), and age (younger/older). Non-parametric tests were used to analyze differences in setup errors in : vertical (Vrt), longitudinal (Lng), lateral (Lat) directions, and pitch, roll, and rotation (Rtn) angles. The formula proposed by van Herk was applied to calculate PTV margins.Results:The Vrt direction setup error in the supraclavicular region (0.2 cm) was smaller than that in the chest wall region (0.26 cm), but errors and margin expansions in other directions were larger ( P<0.05 for Lng and Lat directions). No significant correlation was observed in Vrt direction errors between the two sites ( P=0.062), while significant correlations were found in the other directions and angles (all P<0.05). As treatment progressed, setup errors increased in the Vrt and Rtn directions for the supraclavicular region, and in the Vrt, Lng, Lat directions and Rtn angle for the chest wall region. Among these, only the increase in Lat direction error for the chest wall region was statistically significant ( P=0.028). The PTV margins in the late phase group (except for the Lat direction of the supraclavicular region) were greater than or equal to those in the early phase group. Elderly patients had significantly larger setup errors than younger patients in Vrt, Lng, and Lat directions for the supraclavicular region, as well as in Vrt and Lat directions for the chest wall region (all P<0.05). Conclusions:In dual-isocenter radiotherapy for breast cancer, the supraclavicular region requires larger PTV margins than the chest wall region, and elderly patients require greater margins overall. Mid-course rescanning is recommended. If cone-beam CT guidance cannot be ensured for every session, expansion of PTV margins should be considered for the supraclavicular region and elderly patients to reduce the risk of geographic miss.

Objective To evaluate the efficacy of four-dimensional traction in elderly patients with degenera-tive lumbar spinal stenosis(DLSS),focusing on changes in lumbar muscle morphology and mechanical properties.Methods Elderly patients with DLSS admitted to the Second Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2022 to February 2024 were enrolled.Based on the treatment method,they were categorized into the study group(muscle exercise combined with four-dimensional traction,n=40)and the control group(routine muscle exercise,n=40).All participants underwent a 4-week treatment regimen and subsequently received multimodal ultrasound examinations.The morphology and mechanical properties of the lumbar muscle group,lumbar range of motion,walking distance in intermittent claudication,Visual Analogue Scale(VAS),and Oswestry Disability Index(ODI)scores were compared between the two groups.Results After treatment,the study group exhibited significantly greater improvements in multifidus muscle thickness,circumference,cross-sectional area,pressure pain threshold,and lumbar range of motion(P<0.05).In contrast,the shear wave velocity(SWV),Young's modulus,muscle tension,and flexion-extension ratio of the multifidus muscle were significantly lower in the study group(P<0.05).Additionally,the walking distance in intermittent claudication for the study group was markedly longer(P<0.05).During the 12-month follow-up period after treatment,the VAS and ODI scores of the study group remained significantly lower(P<0.05).Conclusion Four-dimensional traction in combination with muscle exercise can effectively alleviate clinical symptoms,enhance muscle function,and improve mechanical properties in elderly patients with DLSS.

Objective:To investigate the effect of myo-inositol on the reactivation of ocular dominance plasticity in the visual cortex of adult mice and its mechanisms.Methods:Thirty-two male SPF-grade C57BL/6J mice at postnatal day 60 (P60) were randomly divided into four groups using a random number table: normal control group, monocular form deprivation (MD) group, myo-inositol group (myo-inositol administered to normal mice), and MD+ myo-inositol group (myo-inositol administered to MD mice), with 8 mice in each group.The right eyes of MD group and MD+ myo-inositol group received MD on P60.Mice in each group were housed until P64 when pattern visual evoked potential (P-VEP) recordings were performed in both eyes.The amplitude and peak time of P100 wave were measured, and the contralateral/ipsilateral ratio (C/I) was calculated to evaluate the shift of ocular dominance.Twenty-four mice were randomly divided into MD group and MD+ myo-inositol group using the random number table method, with 12 mice in each group.RNA was extracted from the visual cortex of the two groups of mice, and transcriptomic sequencing and bioinformatics analysis were performed to screen differentially expressed genes.Six mice were randomly divided into MD group and MD+ myo-inositol group using the random number table method, with 3 mice in each group, and the expression changes of differentially expressed genes cell communication network factor 1( CCN1), fatty acid binding protein 7( Fabp7) and galectin-3 binding protein ( Lgals3bp) were verified by real-time fluorescence quantitative PCR.This study adhered to the Regulations on the Administration of Laboratory Animals (2017 Edition), and the research protocol was approved by the Animal Ethics Committee of Tianjin Medical University (No.TMUaMEC2022004). Results:The P-VEP results showed that the right eye P100 amplitudes in the normal control, MD, myo-inositol and MD+ myo-inositol groups were (89.04±19.87), (83.04±9.42), (88.14±21.75) and (61.75±15.42)μV, and the P100 wave peak time were (102.40±5.64), (101.50±8.26), (101.33±8.66) and (111.30±7.17)ms, and C/I were 2.38±0.17, 2.35±0.22, 2.41±0.31, and 1.65±0.24, respectively, with statistically significant overall differences ( F=5.844, 2.221, 16.634; all P<0.05).Compared with the normal control group, MD group and myo-inositol group, the MD+ myo-inositol group had a significant decrease in the P100 wave amplitude in the right eye, a significant prolongation of the P100 wave peak time, and a significant decrease in the C/I, with statistically significant differences (all P<0.05).There was no significant difference in P100 wave amplitude or peak time in the left eyes among the normal control, MD, myo-inositol and MD+ myo-inositol groups ( F=0.249, 1.356; both P>0.05).The transcriptome sequencing results showed that there were significant differences in the expression of 93 genes between the MD+ myo-inositol group and the MD group, among which the differential expression of CCN1, Fabp7 and Lgals3bp genes related to visual plasticity was particularly significant.The real-time fluorescence quantitative PCR results verified that the expression of CCN1 in the MD+ myo-inositol group was significantly decreased, and the expression of Fabp7 and Lgals3bp was significantly increased, with statistically significant differences ( t=17.561, 9.237, 12.710; all P<0.001). Conclusions:Myo-inositol can effectively reactivate ocular dominance plasticity in the visual cortex in adult mice, and may mediate this process by regulating the expression of specific genes CCN1, Fabp7, and Lgals3bp.

Objective To explore the imaging manifestations of Rosai-Dorfman disease(RDD)in children.Methods A total of 12 children with RDD confirmed by pathology were retrospectively enrolled,including 8 cases underwent non-contrast CT(NCCT)+contrast enhanced CT(CECT),2 cases underwent NCCT+CECT+non-contrast MR(NCMR)+contrast enhanced MR(CEMR),1 case underwent NCCT+NCMR and CEMR,while 1 case underwent NCCT and X-ray examinations.Imaging manifestations of RDD in children were observed.Results Among 12 cases,intranodal type RDD was found in 7 case,extranodal type RDD in 3 cases,and mixed type(with both lymph nodes and extranodal sites affected)RDD were noticed in 2 cases.In 7 cases of intranodal type RDD,NCCT and CECT showed multiple lymph node enlargements in both sides of the neck,with uniform isodensity on NCCT and mild-moderate progressive enhancement in 5 cases,while with low-density necrotic area and ring-shaped enhancement in 2 cases.Among 3 cases of extranodal RDD,the lesion in 1 case involved nasal cavity and posterior group of ethmoid sinuses on CT and MRI,which developed circular soft tissue mass centered on nasal septum with moderate heterogeneous enhancement,also compressed the adjacent bone with destruction.In another case of extranodal RDD,CT showed that the lesion involved left ilium and bilateral parietal bones,with bone destruction accompanied by obvious periosteal reaction and soft tissue mass,which was mildly enhanced.In the rest 1 case of extranodal RDD,CT and X-ray film showed that the lesion involved the upper segment of right femur and left parietal bone,with osteolytic destruction accompanied by layered periosteal reaction.The lesions in both 2 cases of mixed type RDD involved brain(1 case involved left parieto-occipital lobe,1 case involved bilateral temporal lobes,left frontal lobe and bilateral occipital lobes),presented as isodensity on CT and equal or slightly low signal intensity on T 1WI,equal-high mixed signal intensity on T2WI,some shaped like brain gyral with mild edema of surrounding tissue,and nodular or mass-like significant enhancement.RDD involvements of bilateral lung,mediastinum and hilar lymph nodes were also observed in the above 2 cases,chest CT showed multiple nodular or small patchy uniform high-density shadows in bilateral lungs,as well as enlarged mediastinum and hilar lymph nodes.Conclusion Imaging manifestations of pediatric RDD had certain specificity,being helpful to diagnosis.
