OBJECTIVE To analyze the clinical characteristics and influential factors of drug-induced liver injury （DILI） in children caused by intravenous azithromycin. METHODS Clinical data of 157 DILI pediatric cases caused by intravenous azithromycin， reported by the Hengshui Adverse Drug Reaction Monitoring Center from January 2015 to January 2025， were collected as the observation group. Clinical data of pediatric patients who received intravenous azithromycin but did not develop DILI during the same period at Hengshui People’s Hospital were collected in a 1∶1 ratio to serve as the control group. The clinical classification， severity and prognosis of DILI in pediatric patients from the observation group were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for DILI in children caused by intravenous azithromycin. RESULTS Among 157 DILI cases， 92 cases （58.60%） had hepatocellular injury-type， 51 cases （32.48%） had cholestatic-type， and 14 cases （8.92%） had mixed-type. DILI severity was grade 1 in 117 cases （74.52%）， grade 2 in 33 cases （21.02%）， and grade 3 in 7 cases （4.46%）. Liver function had all recovered after stopping medication and symptomatic treatment. Combined with acetaminophen [OR＝3.769， 95%CI （1.615， 8.235）， P＝0.021]， daily dose of azithromycin＞10 mg/kg [OR＝ 2.237， 95%CI （1.075， 4.655）， P＝0.034] were independent risk factors for DILI in children caused by intravenous azithromycin. CONCLUSIONS Hepatocellular injury-type and cholestatic-type are relatively common in children with DILI caused by intravenous azithromycin， with mild severity being predominant and showing a favorable prognosis. Combination with acetaminophen and daily dose＞10 mg/kg are independent risk factors for azithromycin-induced DILI in children.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

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.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Lysine-specific demethylase 1 (LSD1) is the firstly discovered histone demethylase. In recent years, LSD1 has become a hot topic in the study of the development and progression of malignancies, and its expression is closely related to the poor prognosis of malignancies. At present, some studies have showed that LSD1 is strongly related to the proliferation, invasion and metastasis of triple-negative breast cancer (TNBC). However, the specific mechanism is not fully understood. This article summarizes the possible mechanism of the development and progression in LSD1 and TNBC, and reviews the latest progress of LSD1 in the clinical research application of TNBC, so as to provide a reference for drug combination therapy in TNBC patients.

The incidence of blood tumors is getting higher and higher. In addition to traditional chemoradiotherapy, in recent years, with the development of nuclear medicine technology and nuclide, nuclide therapy is playing an increasingly important role in the treatment of blood tumors. At present, the main research on the treatment of blood tumors focuses on acute myeloid leukemia (AML), but progress has also been made in other blood tumors. 213Bi and 225Ac-labeled monoclonal antibodies have achieved good results in blood tumors. 225Ac has overcome the short half-life of 213Bi and the problems of transportation and preservation. However, there are still many problems to be solved in the clinical use of α particles. This article reviews the progress of α-particle therapy in blood system, in order to provide a broader idea for the treatment of blood tumors.

Objective:To evaluate the real-world safety of the domestic rotavirus attenuated live vaccine in China.Methods:Studies on the incidence of adverse event following immunization (AEFI) published from January 1, 2020 to July 31, 2023 were retrieved from National Knowledge Infrastructure (CNKI), CQVIP, Wanfang Database, PubMed, Medline, and Embase. Surveillance data about AEFI reports related to the domestic rotavirus vaccine rotavirus were collected. A meta-analysis on the safety of the rotavirus vaccine after vaccination was conducted using R software, and subgroup analyses were conducted on the incidence of AEFI in different regions and time periods.Results:A total of 36 articles were included involving 25.332 million doses of vaccine. The incidence of AEFI associated with the domestic rotavirus vaccine was 19/100 000 doses [95%CI: 15/100 000-24/100 000 doses]; the incidence was 26/100 000 doses [95%CI: 17/100 000-39/100 000 doses] in the northern regions and 16/100 000 doses [95%CI: 11/100 000-23/100 000 doses] in the southern regions; it was 24/100 000 doses [95%CI: 12/100 000-45/100 000 doses] before 2017 and 27/100 000 doses [95%CI: 18/100 000-39/100 000 doses] after 2017.Conclusions:The incidence of AEFI related to the domestic rotavirus vaccine is within the expected range, and the safety of the vaccine is good based on the real-world data.

Objective To investigate the predictive value of systemic immune inflammation index(SII)scores in long-term survival of patients with stage Ⅲ squamous lung cancer treated with radical radiotherapy.Methods Clinical data of stage Ⅲ squamous lung cancer patients who underwent radical radiotherapy at the Radiotherapy Department of the Fourth Hospital of Hebei Medical University from January 2010 to December 2018 were retrospectively analyzed.The peripheral hematological indexes one week before radiotherapy were collected and recorded.X-Tile software was applied to determine the best cut-off values for continuous variables.Kaplan-Meier method was used to analyze overall survival(OS)and progression-free survival(PFS).Results A total of 453 patients were included in this study.There were 336 patients in the low SII group(＜1 277.3),and other 117 patients were in the high SII group(≥1 277.3).The median OS and median PFS in the high SII group were shorter than those in the low SII group(OS:20.8 months vs.31.0 months,Log-rank χ2=18.015,P＜0.01;PFS:13.0 months vs.21.0 months,Log-rank χ2=15.062,P＜0.01).Multivariate Cox regression analysis showed that high SII was associated with OS(HR=1.628,95%CI:1.294-2.047,P<0.001)and PFS(HR=1.559,95%CI:1.240-1.961,P<0.001).Other influencing factors included late TNM stage,poor radiotherapy efficacy and decreased HALP score.Conclusion SII can be used to evaluate the long-term survival of patients with stage Ⅲ lung squamous cell carcinoma receiving radical radiotherapy,and the increase of SII indicates a poor prognosis.
