With the widespread application of chemotherapy, immunotherapy, and targeted therapy, cardiotoxicity associated with anti-tumor treatment has gained increasing attention. Drug-induced cardiac injury can significantly impact patients’ quality of life and may even limit the overall efficacy of anti-tumor therapy. The underlying mechanisms include oxidative stress, inflammatory responses, mitochondrial dysfunction, apoptosis, and immune dysregulation. Owing to multitarget effects, low toxicity, and holistic regulatory properties, Chinese traditional medicines have demonstrated considerable potential in cardioprotection. This review summarizes the principal mechanisms of drug-induced myocardial injury related to anti-tumor therapy and highlights recent advances in the prevention and treatment of cardiotoxicity using Chinese medical formulae, such as compound danshen dripping pills, nuanxinkang, qili qiangxin capsules, and shengmai powder, as well as their bioactive constituents. The cardioprotective effects of these agents are discussed in terms of their antioxidative, anti-inflammatory, immunomodulatory, and mitochondrial-protective actions. Furthermore, it highlights certain traditional medicines that exhibit unique advantages in synergistic cardioprotective and anti-tumor therapy. Future efforts should focus on well-designed, systematic clinical studies to facilitate the translational application of integrated Chinese and Western medicine in cardio-oncology.

Objective:To explore the impact of female body mass index (BMI) on pregnancy outcomes in artificial insemination with donor sperm (AID).Methods:A retrospective cohort study was conducted on 4 484 couples with 9 852 AID treatment cycles treated at Reproductive Center of Guangdong Institute of Reproductive Science from January 2011 to September 2024. Participants were divided into four groups based on BMI: low BMI group (BMI<18.5 kg/m 2), normal BMI group (18.5 kg/m 2≤BMI<24.0 kg/m 2), overweight group (24.0 kg/m 2≤BMI<28.0 kg/m 2), and obese group (BMI≥28.0 kg/m 2). General characteristics and pregnancy outcomes were compared across groups. Kaplan-Meier survival analysis was used to calculate cumulative pregnancy rates from one to six cycles. Generalized estimating equations (GEE), univariate and multivariate logistic and Cox regression analysis were performed, adjusting for age, basal follicle-stimulating hormone, basal luteinizing hormone, endometrial thickness, clinical diagnosis, and treatment protocol, to explore correlations between female BMI and clinical pregnancy rate, spontaneous abortion rate, and cumulative pregnancy rate. Results:1) There were no statistically significant differences in clinical pregnancy rate and spontaneous abortion rate among the low BMI group, the normal BMI group, the overweight group, and the obesity group (all P>0.05). 2) Cumulative pregnancy rates for AID cycles 1-6 were 17.60%, 31.60%, 43.08%, 54.37%, 61.83% and 73.68%, respectively. 3) Multivariate GEE analysis revealed that female age ( OR=0.962, 95% CI: 0.950-0.974, P<0.001), endometrial thickness ( OR=1.040, 95% CI:1.011-1.069, P=0.006), and natural cycles ( OR=1.171, 95% CI: 1.060-1.294, P=0.002) influenced clinical pregnancy rates. Compared with the normal BMI group, there were no statistically significant differences in clinical pregnancy rates of low BMI group, overweight group, and obese group (all P>0.05). Multivariate logistic analysis showed that female age ( OR=1.051, 95% CI: 1.012-1.091, P=0.010), endometrial thickness ( OR=0.920 , 95% CI: 0.847-1.000, P=0.049) and polycystic ovary syndrome ( OR=1.927, 95% CI: 1.044-3.556, P=0.036) influenced spontaneous abortion rates. Compared with the normal BMI group, there were no statistically significant differences in spontaneous abortion rates of low BMI group, overweight group and obese group (all P>0.05). 4) Cox regression analysis indicated that female age ( HR=0.939, 95% CI: 0.928-0.950, P<0.001), endometrial thickness ( HR=1.039, 95% CI: 1.013-1.066, P=0.003) and natural cycles ( HR=1.957, 95% CI: 1.785-2.146, P<0.001) influenced cumulative pregnancy rates. Compared with the normal BMI group, there were no statistically significant differences in cumulative pregnancy rates of low BMI group, overweight group and obese group (all P>0.05). Conclusion:Female BMI does not significantly affect clinical pregnancy rates, spontaneous abortion rates and cumulative pregnancy rates in AID.

Objective To observe the rehabilitation treatment effect of using a comprehensive quality control model based on ICF concept and PDCA cycle management mode to intervene in stroke recovery patients.Methods The time segmenta-tion method was employed for grouping.A total of 114 stroke patients admitted to the hospital from June 1,2022 to February 28,2023 were selected as the control group,and 109 patients admitted from March 1,2023 to November 1,2023 were chosen as the study group.There was no statistically significant difference in the clinical data of the two groups of patients before treatment.The control group received conventional rehabilitation treatment,while the study group implemented the rehabilitation treatment based on the ICF concept and the PDCA"big loop with small loops"cyclic management mode on the basis of the control group.The basic information of the two groups of patients was compared,and the rehabilitation effects of the patients were comprehensively e-valuated by using the Fugl-Meyer assessment of upper and lower limb functions(with a total of 100 indicators),the Functional Independence Measure(FIM)score of daily activity ability(including 13 motor quality of life indicators and 5 cognitive quality of life indicators),and the satisfaction evaluation.Results After treatment,the scores of upper and lower limb function assess-ment and daily activity ability in both groups were significantly higher than those before treatment.Among them,all the scores of the study group were significantly better than those of the control group(P＜0.01),and the satisfaction of the study group was also significantly improved compared with that of the control group(P＜0.05).Conclusion The comprehensive quality control model based on the ICF concept and the PDCA cycle can significantly improve the rehabilitation effects and patient satisfaction of stroke patients in the recovery period.

Objective To explore the value of vesical imaging reporting and data system(VI-RADS)combined with absolute tumor-wall contact length(ABTCL)and actual tumor-wall contact length(ACTCL)in diagnosing muscle invasive bladder cancer(MIBC).Methods The MRI data of 113 patients with pathologically confirmed bladder cancer(BCa)were analyzed retrospectively.All patients underwent conventional MRI,diffusion weighted imaging(DWI)and dynamic contrast enhanced(DCE)MRI before sur-gery.Two radiologists independently evaluated MRI images based on VI-RADS score,and measured quantitative parameters,inclu-ding ABTCL and ACTCL.The Chi-square test was used to compare the difference of VI-RADS scores between MIBC and non-mus-cle invasive bladder cancer(NMIBC).Quantitative parameters between MIBC and NMIBC were compared by Mann-Whitney U test.The receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of VI-RADS,quantitative parameters and VI-RADS combined with quantitative parameters in the diagnosis of MIBC.Results VI-RADS,ABTCL and ACTCL had significant differences between MIBC and NMIBC(P＜0.05).The area under the curve(AUC)for VI-RADS,ABTCL and ACTCL in diagno-sing MIBC were 0.89,0.76 and 0.77,respectively.There was no significant difference between the AUC for ABTCL and ACTCL(P＞0.05).The AUC for VI-RADS combined with ABTCL or ACTCL in diagnosing MIBC was 0.93,higher than that of only VI-RADS(P＜0.05).Conclusion The combination of VI-RADS with either ABTCL or ACTCL can effectively improve the diagnostic performance of MIBC.ABTCL obtainedby linear measurement is easier to implement in clinical practice than ACTCL obtained by curved measurement.

Objective:To establish the standard of nursing quality in bone oncology department, and provide the basis for scientific evaluation of nursing quality in bone oncology department.Methods:On the theoretical basis of Donabedian′s three-dimensional quality model of "structure-process-outcome", and through literature review and semi-structured interview method, the "evaluation index of nursing quality in bone oncology department" was preliminatively formulated from November 2022 to June 2023. The Delphi method was used to select 31 experts from 31 third-level A hospitals and nursing colleges in 27 provinces or municipalities across the country for two rounds of correspondence consultation. The criteria were screened and modified to determine the evaluation criteria of nursing quality in bone tumor specialty.Results:The questionnaire recovery rate of 2 rounds of expert consultation was 100.00%, the authority coefficient of 2 rounds of expert consultation was 0.93, and the coefficient of variation of 1, 2 and 3-grade standards were all less than or equal to 0.25. The Kendall′s coefficient of concordance of the primary standards of the two rounds of expert consultation were both 0.088, in the secondary standards were 0.103 and 0.140, in the tertiary standards were 0.119 and 0.110. Through 2 rounds of expert letter consultation, the evaluation criteria for the quality of care in bone tumor specialties were divided into three levels, including 3 primary standards (structural quality criteria, process quality criteria and outcome quality criteria), 21 secondary standards and 80 tertiary standards.Conclusions:The construction process of nursing quality standard in bone oncology department is scientific and reliable, reflecting specialty characteristics, and can provide scientific basis for the evaluation of nursing quality in bone oncology department and standardize nursing behavior.

Objective:To evaluate the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with secondary acute myeloid leukemia (sAML) .Methods:In this multicenter, retrospective clinical study, adult patients aged ≥18 years who underwent allo-HSCT for sAML at four centers of the Zhejiang Hematopoietic Stem Cell Transplantation Collaborative Group from January 2014 to November 2022 were included, and the efficacy and prognostic factors of allo-HSCT were analyzed.Results:A total of 95 patients were enrolled; 66 (69.5%) had myelodysplastic syndrome-acute myeloid leukemia (MDS-AML) , 4 (4.2%) had MDS/MPN-AML, and 25 (26.3%) had therapy-related AML (tAML) . The 3-year CIR, LFS, and overall survival (OS) rates were 18.6% (95% CI 10.2%-27.0%) , 70.6% (95% CI 60.8%-80.4%) , and 73.3% (95% CI 63.9%-82.7%) , respectively. The 3-year CIRs of the M-AML group (including MDS-AML and MDS/MPN-AML) and the tAML group were 20.0% and 16.4%, respectively ( P=0.430) . The 3-year LFSs were 68.3% and 75.4%, respectively ( P=0.176) . The 3-year OS rates were 69.7% and 75.4%, respectively ( P=0.233) . The 3-year CIRs of the groups with and without TP53 mutations were 60.0% and 13.7%, respectively ( P=0.003) ; the 3-year LFSs were 20.0% and 76.5%, respectively ( P=0.002) ; and the 3-year OS rates were 40.0% and 77.6%, respectively ( P=0.002) . According to European LeukmiaNet 2022 (ELN2022) risk stratification, the 3-year CIRs of patients in the low-, intermediate-, and high-risk groups were 8.3%, 17.8%, and 22.6%, respectively ( P=0.639) . The three-year LFSs were 91.7%, 69.5%, and 65.6%, respectively ( P=0.268) . The 3-year OS rates were 91.7%, 71.4%, and 70.1%, respectively ( P=0.314) . Multivariate analysis revealed that advanced disease at allo-HSCT and TP53 mutations were independent risk factors for CIR, LFS, and OS. Conclusion:There was no significant difference in the prognosis of patients who underwent allo-HSCT among the MDS-AML, MDS/MPN-AML, and tAML groups. Advanced disease at transplantation and TP53 mutations were poor prognostic factors. ELN2022 risk stratification had limited value for predicting the prognosis of patients with sAML following allo-HSCT.

T cell infiltration and proliferation in tumor tissues are the main factors that significantly affect the therapeutic outcomes of cancer immunotherapy. Emerging evidence has shown that interferon-gamma (IFNγ) could enhance CXCL9 secretion from macrophages to recruit T cells, but Siglec15 expressed on TAMs can attenuate T cell proliferation. Therefore, targeted regulation of macrophage function could be a promising strategy to enhance cancer immunotherapy via concurrently promoting the infiltration and proliferation of T cells in tumor tissues. We herein developed reduction-responsive nanoparticles (NPs) made with poly (disulfide amide) (PDSA) and lipid-poly (ethylene glycol) (lipid-PEG) for systemic delivery of Siglec15 siRNA (siSiglec15) and IFNγ for enhanced cancer immunotherapy. After intravenous administration, these cargo-loaded could highly accumulate in the tumor tissues and be efficiently internalized by tumor-associated macrophages (TAMs). With the highly concentrated glutathione (GSH) in the cytoplasm to destroy the nanostructure, the loaded IFNγ and siSiglec15 could be rapidly released, which could respectively repolarize macrophage phenotype to enhance CXCL9 secretion for T cell infiltration and silence Siglec15 expression to promote T cell proliferation, leading to significant inhibition of hepatocellular carcinoma (HCC) growth when combining with the immune checkpoint inhibitor. The strategy developed herein could be used as an effective tool to enhance cancer immunotherapy.

Objective:To explore the mechanism of bone morphogenetic protein 2 (BMP-2) regulating pulmonary vascular remodeling in pulmonary hypertension (PH).Methods:Pulmonary artery smooth muscle cells (PASMC) groups: control group, PH group, PH+BMP-2 group, PH+BMP-2+ small interfering BMP receptor(si-BMPR)-Ⅰa group, PH+BMP-2+ si-BMPR-Ⅰb group, PH+BMP -2+si-BMPR-Ⅱ group. In vitro PH model was induced by hypoxia. The three BMP-2 receptors were silenced by the transfection of si-BMPR-Ⅰa, si-BMPR-Ⅰb and si-BMPR-Ⅱ plasmids, respectively. Cell proliferation and apoptosis in each group were detected, transient receptor potential ion channel C1/6 (TRPC1/6), p21 mRNA and protein levels, and intracellular Ca 2+ concentration were detected. Results:The intracellular Ca 2+ concentration in the PH group was higher than that in the control group: (785.15 ± 44.26) nmol/L vs. (224.15 ± 15.87) nmol/L, the and apoptosis rate was lower than that in the control group: (3.15 ± 0.22)% vs. (7.31 ± 0.45)%, there were statistical differences ( P<0.05). The intracellular Ca 2+ concentration in the PH+BMP-2 group was (297.64 ± 21.46) nmol/L, and was lower than that in the PH group, and apoptosis rate was (6.88 ± 0.75)%, and was higher than that in the PH group, there were statistical differences ( P<0.05). The intracellular Ca 2+ concentration in the PH+BMP-2+si-BMPR-Ⅰa group, PH+BMP-2+ si-BMPR-Ⅰb group, PH+BMP -2+si-BMPR-Ⅱ group was (412.31 ± 29.57), (384.34 ± 30.66), (695.23 ± 39.85) nmol/L, and was higher than that in the PH+BMP-2 group, and apoptosis rate was (4.10 ± 0.27)%, (4.26 ± 0.28)%, (3.33 ± 0.24)%, and was lower than that in the PH+BMP-2 group, there were statistical differences ( P<0.05). The intracellular Ca 2+ concentration in the PH+BMP -2+si-BMPR-Ⅱ group was higher than that in the PH+BMP-2+si-BMPR-Ⅰa group and PH+BMP-2+ si-BMPR-Ⅰb group, the apoptosis rate was lower than that in the PH+BMP-2+si-BMPR-Ⅰa group and PH+BMP-2+ si-BMPR-Ⅰb group, there were statistical differences ( P<0.05). Conclusions:BMP-2 mainly inhibits the expression of TRPC1/6 by interacting with the receptor BMPR-Ⅱ, inhibits the influx of Ca 2+ and promotes the expression of p21, thereby inhibiting the proliferation of PASMC and promoting apoptosis, participating in pulmonary vascular remodeling in PH.
