Ferroptosis has received great attention as an iron-dependent programmed cell death for efficient cancer therapy. However, with the accumulation of iron in tumor cells, the antioxidant system is activated by reducing glutathione (GSH) with glutathione peroxidase 4 (GPX4), which critically limits the ferroptosis therapeutic effect. Herein, an iron and GPX4 silencing siRNA (siGPX4) co-encapsulated ferritin nanocage (HFn@Fe/siGPX4) was developed to enhance ferroptosis by disruption of redox homeostasis and inhibition of antioxidant enzyme synergistically. The siGPX4 were loaded into the nanocages by pre-incubated with iron, which could significantly improve the loading efficiency of the gene drugs when compared with the reported gene drug loading strategy by ferritin nanocages. And more iron was overloaded into the ferritin through the diffusion method. When HFn@Fe/siGPX4 was taken up by human breast cancer cell MCF-7 in a TfR1-mediated pathway, the excess iron ions in the drug delivery system could for one thing induce ferroptosis by the production of reactive oxygen species (ROS), for another promote siGPX4 escaping from the lysosome to exert gene silencing effect more effectively. Both the in vitro and in vivo results demonstrated that HFn@Fe/siGPX4 could significantly inhibit tumor growth by synergistical ferroptosis. Thus, the developed HFn@Fe/siGPX4 afforded a combined ferroptosis strategy for ferroptosis-based antitumor as well as a novel and efficient gene drug delivery system.

OBJECTIVE To investigate the effectiveness of resident clinical pharmacist-led medication therapy management (MTM) model in geriatric cardiology departments, and provide reference for optimizing resident pharmaceutical services. METHODS A retrospective cohort study was conducted, incorporating data from inpatients admitted to the Department of Cardiovascular Medicine in the Geriatric Medical Center of our hospital during March to August 2023 (conventional group, n= 903) and the same period in 2024 (MTM group, n=963). The conventional group received only standard pharmaceutical services (including prospective prescription review and retrospective order evaluation), while the MTM group received additional resident clinical pharmacist-led interventions-such as medication reconciliation, personalized therapeutic drug monitoring (TDM), standardized intravenous infusion management, and a four-stage closed-loop monitoring process-based on conventional care. The effectiveness of the MTM model was evaluated by comparing the primary outcome measures (e.g., intravenous infusion rate, TDM target attainment rate) and secondary outcome measures [e.g., incidence of drug-drug interactions (DDIs), incidence of grade 3 or higher acute kidney injury, average length of hospital stay, cholesterol, and medication cost per capita] between the two groups. RESULTS Compared with the conventional group, in terms of primary outcome indexes: both the overall intravenous infusion rate and the use rate of acid-suppressive injection were significantly lowered in the MTM group (P<0.05); serum concentration target attainment rates for digoxin and vancomycin were increased significantly (P<0.05). For secondary outcome indexes, the MTM group exhibited significant decreases in the work incidence of grade 3 or higher acute kidney injury, the incidence of DDIs, the rate of patients leaving the hospital against medical advice, alanine amino-transferase, aspartate transferase and the per capita total medication cost (P<0.05). Additionally, there was a notable increase in the creatinine, estimated glomerular filtration rate and a significant shortening of the per capita length of hospital stay (P<0.05). CONCLUSIONS The resident clinical pharmacist-led MTM model can significantly optimize medication therapy processes, enhance medication safety and cost-effectiveness, thus playing a positive role in promoting rational drug use and improving patient outcomes.

Objective:To explore the value of ultrasound features modified version 2022 of the Ovarian-Adnexal Imaging Reporting and Data System(O-RADS)Category 4 in the differential diagnosis of benign and malignant ovarian-adnexal tumors.Methods:Retrospective analysis was conducted in 501 cases with ovarian masses classified into 4 categories according to the 2022 version of O-RADS who were collected from 4 clinical centers[the Second Afliated Hospital of Harbin Medical University(188 cases),Zhejiang Provincial People's Hospital(146 cases),Sichuan Provincial Maternity and Child Health Care Hospital(90 cases),and Fuling Hospital of Chongqing University(77 cases)]from January 2018 to July 2024 with concomitant surgical resection.The 424 cases from 3 of the clinical centers(the Second Hospital of Harbin Medical University,Zhejiang Provincial People's Hospital,and Sichuan Maternal and Child Health Hospital)were randomly divided into a training group(339 cases)and an internal validation group(85 cases)according to an 8∶2 randomization,while the cases from the other clinical center(Fuling Hospital of Chongqing University)were selected as the external validation group(77 cases),and the pathological diagnosis was used as the “gold standard”.Univariate and multifactorial logistic regression analyses were performed on the ultrasound characteristics of the training group to screen the independent predictors associated with ovarian carcinogenesis,and to formulate the stratification rules for the 4 types of masses in O-RADS. The ROC curve of this stratification method was plotted and the area under the curve(AUC)was calculated,and it was validated in the internal validation group and the external validation group;and the diagnostic accuracy was compared with that of the 2022 version of O-RADS.Results:Univariate logistic analysis showed that cysts with solid components,≥ 4 papillary projections,smooth inner wall of the cyst,color flow score ≥ 3 points,and acoustic shadowing were independent predictors of ovarian cancer(all P < 0.05);while multifactorial logistic analysis showed that cysts with a solid component and a color flow score ≥3 points were independent risk factors of ovarian cancer(all P < 0.05),and smooth cyst walls and acoustic shadows were independent protective factors(all P < 0.05).The diagnostic accuracies of the modified training group,internal validation group,and external validation group were 73.7%,68.2%,70.1%,respectively,which were significantly higher than the diagnostic accuracies of the 2022 version of the O-RADS(38.9%,37.6%,33.8%)(all P < 0.05).The diagnostic sensitivity,specificity and AUC of the training group were 0.871,0.652,0.762,respectively,while the internal validation group were 0.844,0.585,0.714,and 0.846,0.627,0.737 in the external validation group. Conclusions:Improvement of the 2022 version of O-RADS category 4 using ultrasound features may improve the identification of benign and malignant ovarian-adnexal tumors.

As one of the chronic diseases with high incidence in contemporary society, cervical spondylosis has increasing patient groups who gradually present a low age, and it seriously affects social and public health. Although modern medicine has made great progress in the pathological research and clinical treatment of cervical spondylosis, patients still face gastrointestinal side effects of nonsteroidal anti-inflammatory drugs(NSAIDs), neck pain, limited mobility, upper limb numbness, and other symptoms after conservative or surgical treatment. In the theory of traditional Chinese medicine(TCM), cervical spondylosis belongs to the categories of "Bi syndrome" "stiff neck" "stiff Bi", etc. With the change of the times, the change of lifestyle, and the application of western medicine treatment, the etiology and pathogenesis of TCM in cervical spondylosis also show new characteristics. In terms of etiology and pathogenesis, it involves the invasion of wind, cold, and dampness, long-term strain, liver and kidney deficiency, Qi and blood stasis, which are associated with factors such as cervical degeneration, muscle tension and spasm, intervertebral disc herniation, and nerve root compression in modern medicine. In terms of the evolution of pathogenesis, in the early stage, wind, cold, and dampness, were more common in Xuanfu, resulting in unfavorable muscles and bones, poor flow of Qi and blood, and cervical spondylosis and radiculopathy. Medium-term phlegm stasis and internal knots, sluggish muscles and veins, and long-term weathering and fire are more likely to occur in the vertebral artery and sympathetic radiculopathy. In the later stage, the positive Qi is depleted; the true Yin is damaged, and the viscera Qi and blood are deficient, which is most common in cervical myelopathy. The strategy of treating cervical spondylosis with TCM classic formulas applies Gegen Decoction, Wutou Decoction, Qianghuo Shengshi Decoction, Mahuang Jiazhu Decoction to patients with wind, cold, and dampness. Patients with phlegm dampness and blood stasis are treated with Huoxue Xiaoling Dan, Jinlingzi Powder, Siwu Decoction, Banxia Baizhu Tianma Decoction, Shuanghe Decoction, etc. For those patients with liver, spleen, and kidney deficiency, Huangqi Guizhi Wuwu Decoction, Tianma Gouteng Decoction, Guishao Dihuang Pills, Shenling Baizhu Powder, and Lizhong Decoction are used to invigorate the spleen, nourish Qi and blood, and tonify liver and kidney. In clinical practice, the authors advocate a safe and effective treatment plan of classic formulas based on deficiency and excess, the integration of formulas and syndromes, and the combination of modern research results, so as to relieve symptoms, reduce recurrence, and reduce medical burden.

Gardeniae Fructus, a traditional Chinese medicine, has significant pharmacological activities such as clearing heat and detoxifying, promoting bile secretion and protecting liver injury. It is widely used in clinical practice for treating conditions like fever-induced restlessness, damp-heat jaundice, dysuria with pain, and fire-toxin sores. Gardeniae Fructus has been included in "list of items that are both food and medicine", so it is also used as an ingredient in food and health products. However, recent toxicological studies have shown that Gardeniae Fructus has certain potential hepatotoxicity, and its improper use may pose a risk. Therefore, it is necessary to clarify the dual regulatory effects and their scientific connotations of Gardeniae Fructus on efficacy and toxicity. Based on the current progress in clinical, pharmacological and toxicological researches, this paper will discuss the characteristics and possible mechanisms of the dual effects of efficacy and toxicity of Gardeniae Fructus, and propose thoughts on the rational clinical use and scientific supervision of Gardeniae Fructus.

OBJECTIVES:
To study the clinical and genetic characteristics of osteopetrosis (OPT) in children.
METHODS:
A retrospective analysis was performed on the clinical data of 14 children with OPT. Whole-exome sequencing was used to detect pathogenic genes, and clinical phenotypes and genotypic features were summarized.
RESULTS:
Among the 14 children (10 males and 4 females), the median age at diagnosis was 8 months. Clinical manifestations included systemic osteosclerosis (14 cases, 100%), anemia (12 cases, 86%), infections (10 cases, 71%), thrombocytopenia (9 cases, 64%), hepatosplenomegaly (8 cases, 57%), and developmental delay (5 cases, 36%). Malignant osteopetrosis (MOP) cases had lower platelet counts, creatine kinase isoenzyme, and serum calcium levels, but higher white blood cell counts, lactate dehydrogenase, and alkaline phosphatase levels compared to non-MOP cases (P<0.05). Genetic testing identified 15 variants in 12 patients, including 8 variants in the CLCN7 gene (53%), 6 in the TCIRG1 gene (40%), and 1 in the TNFRSF11A gene (7%). Three novel CLCN7 variants were identified: c.2351G>C, c.1215-43C>T, and c.1534G>A. All four patients with TCIRG1 variants exhibited MOP clinical phenotypes. Of the seven patients with CLCN7 variants, 4 presented with intermediate OPT, 2 with benign OPT, and 1 with MOP.
CONCLUSIONS
Clinical phenotypes of OPT in children are heterogeneous, predominantly involving CLCN7 and TCIRG1 gene variants, with a correlation between clinical phenotypes and genotypes.

OBJECTIVES:
To evaluate the causal association between circulating levels of zinc, magnesium, and other minerals and autism spectrum disorder (ASD).
METHODS:
A two-sample Mendelian randomization (MR) analysis was performed using summary statistics from large-scale genome-wide association studies of European populations, including 18 382 ASD cases and 27 969 controls. Genetic data for iron, calcium, and magnesium were obtained from the UK Biobank, and data for zinc and selenium were sourced from an Australian-British cohort. A total of 351 genetic instrumental variables were selected. Causal inference was performed using inverse-variance weighting as the primary analysis method. Sensitivity analyses were performed by Cochran's Q test and MR-PRESSO global test to assess the robustness of the findings.
RESULTS:
No statistically significant causal effect was observed for circulating zinc, magnesium, calcium, selenium, or iron levels on ASD risk (all P>0.05). The odds ratios and 95% confidence intervals from the inverse-variance weighting analysis were 0.934 (0.869-1.003) for zinc, 1.315 (0.971-1.850) for magnesium, 1.055 (0.960-1.159) for calcium, 1.015 (0.953-1.080) for selenium, and 0.946 (0.687-1.303) for iron. Sensitivity analysis revealed significant heterogeneity in the causal association between circulating calcium and ASD (P=0.006), while the effect estimate remained stable after MR-PRESSO correction (P=0.487). The causal effect estimates for the remaining minerals demonstrated good robustness.
CONCLUSIONS
This study did not find significant evidence supporting a causal association between circulating zinc, magnesium, calcium, selenium, or iron levels and ASD risk, providing important clues for the etiology of ASD and precision nutritional interventions.

Chinese Journal of Internal Medicine 2025;64(4):302-308
Objective:To analyze the characteristics of cardiovascular and cerebrovascular diseases in patients with primary aldosteronism (PA) and compare them with age-, sex-, and blood pressure-matched patients with essential hypertension (EH).Methods:This cross-sectional study was conducted at the West China Hospital of Sichuan University. Patients with PA and EH between December 2018 and December 2021 were included. Demographic characteristics, stroke events, coronary artery diseases, peripheral vascular diseases, and cardiac structure and function indicators were analyzed. Propensity score matching (PSM) was used to balance non-study data. The t-test, chi-square test, and Wilcoxon signed-rank test were used for data comparison. The cardiovascular and cerebrovascular damage in the patients with unilateral and bilateral PA were also compared. Results:A total of 336 and 369 patients with PA and EH, respectively, were enrolled in this study. One hundred and ninety-eight patients from each group were included after PSM; no significant differences were found in terms of age, gender, and blood pressure. The prevalence of stroke in the PA group was considerably higher than that in the EH group [12.6% (25/198) vs. 5.6% (11/198), P=0.014], due to the significantly greater risk of ischemic stroke [10.0% (20/198) vs. 4.5% (9/198), P=0.029]. The prevalence of hemorrhagic stroke, coronary artery disease, peripheral arterial stenosis, aorta atherosclerosis, and aneurysm in the PA group were also higher than those in the EH group, but there was no statistical significance (all P>0.05). More patients with PA had concurrent left ventricular hypertrophy [22.2% (44/198) vs. 9.1% (18/198)], left atrial enlargement [40.4% (80/198) vs. 30.3% (60/198)], ventricular septal thickening [50.0% (99/198) vs. 36.9% (73/198)], and aortic widening [21.7% (43/198) vs. 13.1% (26/198)] than those with EH (all P<0.05). Compared with the bilateral PA group, the unilateral PA group had higher prevalence of left ventricular hypertrophy [28.3% (51/180) vs. 13.4% (11/82), P=0.013]. Conclusions:Compared with well-matched patients with EH, patients with PA have significantly higher risks of cardiovascular and cerebrovascular diseases, which are mainly manifested in increased prevalence of stroke and severe damage to the cardiac structure. Patients with unilateral PA may suffer more severe cardiac damage than those with bilateral PA.

ObjectiveTo investigate the role of 4-week high-intensity interval training (HIIT) in modulating the metabolic homeostasis of the pyruvate-lactate axis in the hippocampus of rats with chronic unpredictable mild stress (CUMS) to improve their depressive-like behavior. MethodsForty-eight SPF-grade 8-week-old male SD rats were randomly divided into 4 groups: the normal quiet group (C), the CUMS quiet group (M), the normal exercise group (HC), and the CUMS exercise group (HM). The M and HM groups received 8 weeks of CUMS modeling, while the HC and HM groups were exposed to 4 weeks of HIIT starting from the 5th week (3 min (85%-90%) Smax+1 min (50%-55%) Smax, 3-5 cycles, Smax is the maximum movement speed). A lactate analyzer was used to detect the blood lactate concentration in the quiet state of rats in the HC and HM groups at week 4 and in the 0, 2, 4, 8, 12, and 24 h after exercise, as well as in the quiet state of rats in each group at week 8. Behavioral indexes such as sucrose preference rate, number of times of uprightness and number of traversing frames in the absenteeism experiment, and other behavioral indexes were used to assess the depressive-like behavior of the rats at week 4 and week 8. The rats were anesthetized on the next day after the behavioral test in week 8, and hippocampal tissues were taken for assay. LC-MS non-targeted metabolomics, target quantification, ELISA and Western blot were used to detect the changes in metabolite content, lactate and pyruvate concentration, the content of key metabolic enzymes in the pyruvate-lactate axis, and the protein expression levels of monocarboxylate transporters (MCTs). Results4-week HIIT intervention significantly increased the sucrose preference rate, the number of uprights and the number of traversed frames in the absent field experiment in CUMS rats; non-targeted metabolomics assay found that 21 metabolites were significantly changed in group M compared to group C, and 14 and 11 differential metabolites were significantly dialed back in the HC and HM groups, respectively, after the 4-week HIIT intervention; the quantitative results of the targeting showed that, compared to group C, lactate concentration in the hippocampal tissues of M group, compared with group C, lactate concentration in hippocampal tissue was significantly reduced and pyruvate concentration was significantly increased, and 4-week HIIT intervention significantly increased the concentration of lactate and pyruvate in hippocampal tissue of HM group; the trend of changes in blood lactate concentration was consistent with the change in lactate concentration in hippocampal tissue; compared with group C, the LDHB content of group M was significantly increased, the content of PKM2 and PDH, as well as the protein expression level of MCT2 and MCT4 were significantly reduced. The 4-week HIIT intervention upregulated the PKM2 and PDH content as well as the protein expression levels of MCT2 and MCT4 in the HM group. ConclusionThe 4-week HIIT intervention upregulated blood lactate concentration and PKM2 and PDH metabolizing enzymes in hippocampal tissues of CUMS rats, and upregulated the expression of MCT2 and MCT4 transport carrier proteins to promote central lactate uptake and utilization, which regulated metabolic homeostasis of the pyruvate-lactate axis and improved depressive-like behaviors.

Exosomal circular RNA (circRNAs) are pivotal in cancer biology, and tumor pathophysiology. These stable, non-coding RNAs encapsulated in exosomes participated in cancer progression, tumor growth, metastasis, drug sensitivity and the tumor microenvironment (TME). Their presence in bodily fluids positions them as potential non-invasive biomarkers, revealing the molecular dynamics of cancers. Research in exosomal circRNAs is reshaping our understanding of neoplastic intercellular communication. Exploiting the natural properties of exosomes for targeted drug delivery and disrupting circRNA-mediated pro-tumorigenic signaling can develop new treatment modalities. Therefore, ongoing exploration of exosomal circRNAs in cancer research is poised to revolutionize clinical management of cancer. This emerging field offers hope for significant breakthroughs in cancer care. This review underscores the critical role of exosomal circRNAs in cancer biology and drug resistance, highlighting their potential as non-invasive biomarkers and therapeutic targets that could transform the clinical management of cancer.
