BACKGROUND:Ferroptosis is an iron-dependent regulatory form of cell death characterized by iron-dependent lipid peroxidation.Long-chain acyl-coenzyme A synthase 4(ACSL4)is involved in the formation of lipid peroxidation substrates,thereby resulting in ferroptosis.Recent studies have shown that ACSL4-mediated ferroptosis plays a key role in atherosclerotic cardiovascular disease. OBJECTIVE:To summarize the structural function and regulatory mechanism of ACSL4 and its potential molecular mechanism mediating ferroptosis,and to elaborate the application of ACSL4 driving ferroptosis in atherosclerosis,ischemic stroke and myocardial infarction,in order to provide a new therapeutic strategy for the treatment of atherosclerotic cardiovascular diseases. METHODS:Relevant literature was searched in PubMed database from database inception to August 2023 using the keywords of"atherosclerosis,ferroptosis,long-chain acyl-coenzyme A synthase 4,ACSL4,glutathione peroxidase 4,ischemic stroke,myocardial infarction,endothelial cell,smooth muscle cells,foam cell."Finally,76 documents were included for review and analysis. RESULTS AND CONCLUSION:ACSL4 participates in the formation of coenzyme derivatives of polyunsaturated fatty acids and inserts them into phospholipids to provide substrates for lipid peroxidation,the core mechanism of iron death.Among the regulatory factors of ACSL4 expression,integrin α6β4,intracellular vesicular transport factor p115,and zinc lipoprotein A20 negatively regulate its expression.Meanwhile,multiple miRs down-regulate its expression by binding to 3'-UTR.On the contrary,up-regulation of ACSL4 is mostly regulated by transcription factors.ACSL4-dependent production of phospholipids containing polyunsaturated fatty acids is an essential prerequisite for lipid peroxidation and ferroptosis.Moreover,ACSL4 and glutathione peroxidase 4 are mutually dependent as positive and negative regulators of ferroptosis,and their specific mechanisms remain to be further studied.ACSL4-mediated ferroptosis is involved in the pathological mechanism of atherosclerosis,ischemic stroke,and myocardial infarction.Endothelial cell injury in atherosclerosis is closely related to ACSL4-mediated ferroptosis,but there are no reports on the involvement of ACSL4 in foam cell formation,smooth muscle cell phenotype transformation,and calcification.ACSL4 has become a research hotspot as a biomarker and potential target of ferroptosis.Targeting ACSL4 to inhibit ferroptosis may become a new direction for the treatment of atherosclerotic cardiovascular diseases.However,there are few studies on drugs inhibiting ACSL4,and further studies are needed in the future.

BACKGROUND:In recent years,with the rapid development of biomedicine,the study of brain aging and exosomes has attracted more and more attention,but there is no bibliometrics analysis in this field. OBJECTIVE:To objectively analyze domestic and foreign literature on brain aging and exosomes in the past 15 years,to summarize the research status,hot spots,and development trends in this field. METHODS:Using the core database of Web of Science as a search platform,we downloaded the literature on brain aging and exosomes published from the establishment of the database to December 28,2022,and analyzed the data from the aspects of country or region,institution,author,keywords,and co-cited literature using CiteSpace 6.1.R6 visualization software. RESULTS AND CONCLUSION:A total of 1 045 research articles were included,and the number of publications on brain aging and exosomes research both domestically and internationally was showing an increasing trend year by year.The United States ranked first with 429 papers,and China ranked second with 277 papers.Louisiana State University ranked first with 16 articles.Professor Lukiw Walter J from Louisiana State University in the United States was the author with the highest number of publications,and Professor Bartel DP from the Massachusetts Institute of Technology was the author with the most citations.The most prolific Journal was the International Journal of Molecular Sciences.Alzheimer's disease,microRNA,gene expression,extracellular vesicles,exosomes,oxidative stress,and biomarkers are the most relevant terms.According to the research on hot topics,biomarkers have become a new research hotspot.The above results indicate that the research on brain aging and exosomes has gradually increased in the past 15 years.The research direction has gradually shifted from the initial exploration of the expression of miRNAs in central nervous system diseases related to brain aging to the search for biomarkers that can identify and diagnose neurodegenerative diseases.The study of exocrine miRNAs to protect central nervous system from damage has emerged as promising therapeutic strategy.

ObjectiveTo explore the distribution pattern of tongue image characteristics in patients with glucolipid metabolic disorders and its main syndromes. MethodsA total of 841 patients with glucolipid metabolic disorders (disease group), and 380 healthy subjects (control group) were included. The disease group was classified into three syndrome types: 283 cases of liver depression and spleen deficiency syndrome, 311 cases of phlegm-dampness obstruction syndrome, and 247 cases of qi stagnation and blood stasis syndrome. Tongue image data were collected using the TFDA-1 Tongue Diagnosis Instrument, and the TDAS V3.0 software was used to analyze the color, texture, and morphological features of the tongue body (TB) and tongue coating (TC) in patents with different syndromes of disease group (including lightness (L), red-green axis (a), yellow-blue axis (b), luminance (Y), difference between red signal and brightness (Cr), difference between blue signal and brightness (Cb), contrast (CON), angular second moment (ASM), entropy (ENT), mean value (MEAN), tongue coating area/tongue surface area (perAll), and tongue coating area/non-coated area (perPart)). Logistic regression analysis was conducted to identify influencing factors for different syndrome types of glucolipid metabolic disorders. ResultsThe tongue body indicators TB-L, TB-Y, and TB-Cb in the disease group were significantly higher than those in the control group, while TB-a, TB-b, and TB-Cr were significantly lower. The tongue coating indicators TC-L, TC-Y, TC-Cb, perAll, and perPart in the disease group were significantly higher than those in the control group, while TC-a, TC-b, and TC-Cr were significantly lower (P<0.05). Comparing with the different syndromes in disease group, the TB-L and TB-Y of the liver depression and spleen deficiency syndrome, and the phlegm-damp obstruction syndrome were higher than those of the qi stagnation and blood stasis syndrome; the TB-a and TB-Cr of the phlegm-damp obstruction syndrome were lower than those of the qi stagnation and blood stasis syndrome; the perAll of the phlegm-damp obstruction syndrome was higher than that of the qi stagnation and blood stasis syndrome (P<0.05). In the analysis of the morphological characteristics of tongue signs, more spotted tongue in disease group compared with control group, more teeth-marked tongue in liver depression and spleen deficiency syndrome than the other two syndromes, more greasy coating in phlegm-damp obstruction syndrome, and more stasis spots of tongue in qi stagnation and blood stasis syndrome (P<0.05). Logistic regression analysis identified that greasy coating, spotted tongue, stasis spots of tongue, tooth-marked tongue, perAll, and TB-Cb are the influencing factors of liver depression and spleen deficiency syndrome; greasy coating, tooth-marked tongue, TC-Cb, and TC-Cr are the influencing factors of phlegm-damp obstruction syndrome; cracked tongue, stasis spots of tongue, tooth-marked tongue, and TB-Y are the influencing factors of qi stagnation and blood stasis syndrome (P<0.05). ConclusionCompared to healthy individuals, patients with glycolipid metabolic disorder have darker tongue color and thicker, greasy tongue coating. Glycolipid metabolic disorder patients of liver depression and spleen deficiency syndrome exhibit a reddish tongue with finer textures and more tooth marks; patients of phlegm-damp obstruction syndrome have lighter tongue coating with a coarser texture and a higher prevalence of greasy coating; patients of qi stagnation and blood stasis syndrome display lower tongue brightness with a higher prevalence of blood stasis spots.

ObjectiveTo explore the molecular mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer (NSCLC) by inducing ferroptosis via poly(rC)-binding protein 1 (PCBP1). MethodsThe serum containing Buzhong Yiqitang was prepared and cisplatin-resistant human non-small cell lung cancer (NSCLC) cells (A549/DDP) were cultured and randomly grouped as follows: Blank (10% blank serum), model (10% blank serum+20 mg·L-1 cisplatin), Buzhong Yiqitang (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin), Fe-1 (10% blank serum+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1), and Buzhong Yiqitang+Fe-1 (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1). Firstly, PCR Array was used to screen ferroptosis-related genes regulated by Buzhong Yiqitang, and PCBP1 was identified as the target for studying the attenuation of cisplatin resistance by Buzhong Yiqitang. Subsequently, the median inhibitory concentration (IC50) of cisplatin in each group was determined by the cell counting kit-8 (CCK-8) method and the resistance index (RI) was calculated. The ultrastructure of A549/DDP cells in each group was observed by transmission electron microscopy. The protein levels of PCBP1 and glutathione peroxidase 4 (GPX4) were determined by Western blot. The lipid reactive oxygen species (ROS) content in each group was determined by the C11-BODIRY 581/591 fluorescence probe. The ferrous ion assay kit was used to measure the ferrous ion content in each group. The malondialdehyde (MDA) assay kit was used to determine the MDA content in each group. ResultsCompared with model group, the IC50 of cisplatin and the RI of A549/DDP cells decreased in the Buzhong Yiqitang group (P<0.05) but increased in the Fe-1 group (P<0.05). The IC50 of cisplatin and the RI of A549/DDP cells in the Buzhong Yiqitang+Fe-1 group were lower than those in the Fe-1 group (P<0.05). Compared with the model group, the Buzhong Yiqitang group showed obvious mitochondrial ferroptosis, while the mitochondrial damage became less obvious after Fe-1 treatment. Compared with that in the Fe-1 group, the mitochondrial ferroptosis was aggravated after the intervention with Buzhong Yiqitang. Compared with blank group, the model group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05) in A549/DDP cells. Compared with model group, the Buzhong Yiqitang group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05), while the Fe-1 group showed up-regulated expression levels of PCBP1 and GPX4 (P<0.05) and reduced content of lipid ROS, ferrous ions, and MDA (P<0.05). Compared with the Fe-1 group, the Buzhong Yiqitang+Fe-1 group showed down-regulated expression levels of PCBP1 and GPX4 and increased content of lipid ROS, ferrous ions, and MDA (P<0.05). ConclusionBuzhong Yiqitang attenuated cisplatin resistance in NSCLC by regulating PCBP1 to induce ferroptosis.

ObjectiveTo investigate the mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer by observing the effects of Buzhong Yiqitang on endoplasmic reticulum stress-related molecules in human lung adenocarcinoma cells (A549) and cisplatin-resistant cells in human lung adenocarcinoma cells (A549/DDP) via the nuclear factor E2-related factor 2(Nrf2)/reactive oxygen species(ROS) pathway. MethodsThe serum containing Buzhong Yiqitang was prepared and A549 cells and A549/DDP cells were cultured. The cells were randomized into groups A (A549 cells+blank serum), B (A549 cells+20 mg·L-1 cisplatin+blank serum), C (A549 cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum), D (A549/DDP cells+blank serum), E (A549/DDP cells+20 mg·L-1 cisplatin+blank serum), and F (A549/DDP cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum). The cell counting kit-8 (CCK-8) method was used to detect the half maximal inhibitory concentration (IC50) of cisplatin. The protein levels of Nrf2 and p-Nrf2 were determined by Western blotting. The DCFH-DA fluorescent probe was used to measure the content of reactive oxygen species (ROS) in each group. The protein levels of glucose-regulated protein 78 (GRP78), activated transcription factor 6 (ATF6), and C/EBP-homologous protein (CHOP) were determined by Western blot. ResultsCompared with group B, group C showed a reduction in IC50 of cisplatin (P<0.05), which held true in group E compared with group F (P<0.05). Moreover, the IC50 of cisplatin to A549/DDP cells was higher than that to A549 cells before and after Buzhong Yiqitang intervention (P<0.05). Compared with group A, group B showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group B, group C showed down-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group D, group E showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05), which, however, were significantly down-regulated in group F (P<0.05). The ROS content and the protein levels of GRP78, ATF6, and CHOP followed a descending trend of group C > group B > group A in A549 cells and group F > group E > group D in A549/DDP cells (P<0.05). Moreover, the ROS content and the protein levels of GRP78, ATF6, and CHOP in A549 cells were higher than those in A549/DDP cells before and after Buzhong Yiqitang intervention (P<0.05). ConclusionBuzhong Yiqitang may regulate endoplasmic reticulum stress via the Nrf2/ROS pathway to attenuate cisplatin resistance in non-small cell lung cancer.

In the process of tumor chemotherapy, the emergence of multi-drug resistance (MDR) has always been a thorny problem, which is a result of the joint action of the host, tumor cells, and the immune microenvironment. Tumor cells can escape the toxicity of chemotherapeutic drugs through multiple pathways, being easy to produce drug resistance. MDR greatly restricts the effect of chemotherapeutic drugs on tumor cells and affects their therapeutic effects. Traditional Chinese medicine (TCM) has the unique advantages of multi-target, multi-pathway and individualized treatment. The TCM treatment of tumors emphasizes regulating Yin and Yang, as well as reinforcing healthy Qi and dispelling pathogen. In recent years, TCM has demonstrated remarkable efficacy in the treatment of tumors and the amelioration of multi-drug resistance. TCM not only can target the phenomenon of MDR but also greatly weakens the side effects of the patients after the chemotherapy, thus improving the survival quality and rate of the patients. Accordingly, many patients adopt TCM as an adjuvant therapy during or after chemotherapy. The binding of TCM to targets can reverse the drug resistance of various tumors, which has become an emerging research highlight. From the regulatory mechanism of TCM on MDR of tumors, this paper introduces the mechanisms by which tumor cells continue to grow, proliferate, and metastasize by adjusting the intracellular drug concentration, altering or utilizing the tumor microenvironment, and affecting the cell death mode to achieve the resistance to chemotherapeutic drugs. In this regard, the active ingredients and compound prescriptions of TCM can increase the sensitivity of chemotherapeutic drugs by down-regulating drug transporters, improving the tumor microenvironment, and modulating the drug resistance pathways associated with apoptosis, autophagy, ferroptosis, or pyroptosis. The aim of this paper is to explore more clinical practical value of TCM in the treatment of tumors and provide exploratory ideas and a theoretical basis for the future research on tumors and MDR.

OBJECTIVE To evaluate the efficacy, safety and economics of calcium channel modulators in the treatment of diabetic peripheral neuropathic pain (DPNP), and provide evidence-based evidence for clinical drug selection and decision-making. METHODS PubMed, Embase, Cochrane Library, CNKI, Wanfang data, VIP net, CBM and official websites of foreign health technology assessment (HTA) institutions were systematically searched to collect HTA reports, systematic review/meta-analyses, and pharmacoeconomic studies of pregabalin, gabapentin, crisugabalin, and mirogabalin for the treatment of DPNP. The timeframe for all searches was from the inception to June 2024. After data extraction and quality assessment, the results of the included studies were analyzed descriptively. RESULTS A total of 16 articles were included, involving 1 HTA report, 7 systematic reviews/meta- analyses, and 8 pharmacoeconomic studies. No studies on crisugabalin were retrieved. Compared with placebo, both pregabalin and mirogabalin reduced end point pain scores and increased the proportion of patients with ≥30% and/or ≥50% reduction in pain scores. Pregabalin also improved patient global impression of change (PGIC). Gabapentin was similar to placebo in reducing end point pain scores and increasing the proportion of patients with ≥30% and/or ≥50% reduction in pain scores, but gabapentin improved PGIC of patients. Compared with pregabalin, mirogabalin was more effective in the treatment of pain. The safety of pregabalin and mirogabalin was similar, and compared with placebo, both pregabalin and mirogabalin increased the risk of common adverse reactions such as dizziness and somnolence. The safety of gabapentin was similar to placebo and duloxetine. Compared with duloxetine, pregabalin and gabapentin were not cost-effective. Compared with gabapentin, pregabalin was cost-effective. Mirogabalin was cost-effective, as compared with placebo and pregabalin. CONCLUSIONS Pregabalin and mirogabalin are effective in the treatment of DPNP, the efficacy of mirogabalin is better than pregabalin, and the safety is similar between them. The economic conclusions vary from country to country, pending a pharmacoeconomic study based on our population.
9.Trends in disease burden due to childhood asthma from 1990 to 2021 and future projections in China
Chinese Journal of School Health 2025;46(4):573-578
Objective:
To investigate the trends in disease burden due to childhood asthma in China from 1990 to 2021 and to project the disease burden from 2022 to 2035, so as to provide insights into formulation of the control interventions for childhood asthma in China.
Methods:
The prevalent case, agestandard prevalence, disability-adjusted life years (DALYs) and agestandard DALYs rate of children with asthma at ages of 0 to 14 years and their 95% uncertainty interval (UI) in China from 1990 to 2021 were extracted from the Global Burden of Disease (GBD) database. The temporal trends in the disease burden of childhood asthma were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI), and the disease burden due to asthma was projected among children at ages of 0 to 14 years in China using a Bayesian age-period-cohort (BAPC) model from 2022 to 2035.
Results:
There were 9.368 3 million (95%UI=6.410 7 million to 14.026 1 million) prevalent cases of asthma among children at ages of 0 to 14 years in China in 2021, contributing to 0.387 9 million (95%UI=0.216 1 million to 0.668 8 million) DALYs loss. The prevalent cases and DALYs of asthma decreased by 37.28% and 52.55% among children at ages of 0 to 14 years in China in 2021 compared with 1990, and the agestandardized prevalence [EAPC=-0.70%, 95%CI=-1.26% to -0.13%)] and DALY rates [EAPC=-1.71%, 95%CI=-2.32% to -1.10%)] also appeared a tendency towards a decline. From 1990 to 2021, the prevalent cases, prevalence, DALYs and DALYs rate of asthma were all higher among male children than among female children, and the disease burden of asthma was higher among children at ages of 5 to 9 years than at other age groups. BAPC model predicted a decline in both prevalent cases and DALYs of asthma among children at ages of 0 to 14 years in China from 2022 to 2035, with 6.759 6 million prevalent cases and DALYs of 0.228 4 million personyears in 2035, while the prevalence and DALYs rates were projected to rise to 5 143.35/105 and 173.75/105 in 2035.
Conclusions
Despite a reduction in the disease burden of asthma among children at ages of 0 to 14 years in China from 1990 to 2021, the prevalence remained high. The disease burden due to asthma is projected to appear a decline among children at ages of 0 to 14 years in China from 2022 to 2035; however, the prevalence and DALYs rates still rise. Intensified control measures and targeted interventions are required to reduce the disease burden of childhood asthma.

Diabetic kidney disease (DKD) is a common microvascular complication of diabetes. "Internal heat leading to zheng" is the core pathogenesis of DKD, while "glucose toxicity" is transformed from subtle substances through "internal heat" and the cementation of various pathological products, which is pivotal to the transformation of diabetes to DKD. "Glucose toxicity" is characterized by deep and widespread heat, caused by various pathological factors, and its sticky nature makes it difficult to resolve, which can cause severe damage to the kidney collaterals. In the early stage of "glucose toxicity", it is yang pathogen, which can be transformed into yin pathogen in the later stage with disease progression. In clinical practice, treatment should be based on disease staging, with attention on grasping the pathogenesis of "internal heat leading to zheng" and identifying the nature of "glucose toxicity". During the diabetic period, clearing heat is the primary method, often using modified Yueju Pill and Dachaihu Decoction. In the early stage of DKD, treatment primarily focuses on clearing and penetrating latent heat to treat DKD, aiming to prevent toxic heat from transitioning from qi to blood. The approach emphasizes clearing heat and re-penetrating, detoxification, and re-clearing, often using a self-made modified Qingre Xiaozheng Decoction. In the middle and late stages of DKD, the focus shifts to clearing heat, eliminating zheng, strengthening vital qi, and dispelling turbidity, with commonly used treatments including the self-made modified Xiezhuo Xiaozheng Formula, Jingui Shenqi Pill, and Zhenwu Decoction.
