Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

ObjectiveTo investigate the processing technology of calcined Haematitum based on the concept of quality by design（QbD） and to assess its health risk. MethodsTaking whole iron content， Fe²⁺ dissolution content and looseness as critical quality attributes（CQAs）， and calcination temperature， calcination time， spreading thickness and particle size as critical process parameters（CPPs） determined by the failure mode and effect analysis（FMEA）， the processing technology of calcined Haematitum was optimized by orthogonal test combined with analytic hierarchy process-criteria importance through intercriteria correlation（AHP-CRITIC） hybrid weighting method. The contents of heavy metals and harmful elements were determined by inductively coupled plasma mass spectrometry， and the health risk assessment was carried out by daily exposure（EXP）， target hazard quotient（THQ） and lifetime cancer risk（LCR）， and the theoretical value of the maximum limit was deduced. ResultsThe optimal processing technology for calcined Haematitum was calcination at 650 ℃， calcination time of 1 h， particle size of 0.2-0.5 cm， spreading thickness of 1 cm， and vinegar quenching for 1 time［Haematitum-vinegar（10：3）］. The contents of 5 heavy metals and harmful elements in 13 batches of calcined Haematitum were all decreased with reductions of up to 5-fold. The cumulative THQ of 2 batches of samples was>1， while the cumulative THQ of all batches of Haematitum was>1. The LCR of As in 1 batches of Haematitum was 1×10^-6-1×10^-4， and the LCR of the rest was<1×10^-6， and the LCRs of calcined Haematitum were all<1×10^-6， indicating that the carcinogenic risk of calcined Haematitum was low， but special attention should still be paid to Haematitum medicinal materials. Preliminary theoretical values of the maximum limits of Cu， As， Cd， Pb and Hg were formulated as 1 014， 25， 17， 27， 7 mg·kg^-1. ConclusionThe optimized processing technology of calcined Haematitum is stable and feasible， and the contents of heavy metals and harmful elements are reduced after processing. Preliminary theoretical values of the maximum limits of Cu， As， Cd， Pb and Hg are formulated to provide a scientific basis for the formulation of standards for the limits of harmful elements in Haematitum.

Microplastics and nanoplastics (MPs/NPs) are ubiquitous environmental pollutants that act as endocrine-disrupting chemicals (EDCs), raising significant concerns about their impact on human health. Research highlights the hazardous effects of MPs/NPs on both male and female reproductive systems, influencing germ cells, embryo development, and progeny. Additionally, studies show that MPs/NPs affect the gene expression of anabolic steroid hormones in vitro and in vivo, inducing reproductive toxicity through mechanisms such as oxidative stress and inflammation. Considering these adverse effects, identifying natural compounds that can mitigate the toxicity of MPs/NPs is increasingly important. Plants offer a wealth of antioxidants and anti-inflammatory compounds that can counteract these harmful effects. Among these, anthocyanins, natural colorants responsible for the vibrant hues of fruits and flowers, exhibit a wide range of biological activities, including antioxidant, anti-inflammatory, and anti-neoplastic properties. Moreover, anthocyanins can modulate sex hormone levels and alleviate reproductive toxicity. Cyanidin-3-glucoside (C3G), one of the most extensively studied anthocyanins, shows promise in reducing reproductive toxicity, particularly in females, and in protecting male reproductive organs, including the testis and epididymis. This protective effect is believed to result from its interaction with steroid receptors, specifically the androgen and estrogen receptors (ERs). These findings highlight the need to explore the mechanisms by which anthocyanins mitigate the reproductive toxicity caused by MPs/NPs. This review provides novel insights into how natural compounds can be leveraged to lessen the impact of environmental contaminants on human health, especially concerning reproductive health.

Conclusions:Strict blood glucose control during liver transplantation can decrease the development of postoperative liver dysfunction in patients.

Objective To establish the reference interval of serum non-high-density lipoprotein cholesterol(n-HDL-C)in adults in Yan'an city of Shaanxi Province and analyze the influencing factors.Methods A total of 16 921 adults from 10 towns in Yan'an City of Shaanxi Province from January to September 2023 were selected by random sampling.Age,sex,smoking,drinking,exercise,hypertension,diabetes,dyslipidemia,chronic disease,residence,eating habits,marital status,education and monthly income were investigated.Height,weight,waist circumference and blood pressure were measured.Serum triglyceride(TG),total cholesterol(TCHO),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),Apolipoprotein A1(ApoA1),Apolipoprotein B(ApoB)and lipoprotein a[Lp(a)]levels were detected,and n-HDL-C levels were calculated:n-HDL-C(mmol/L)=TCHO(mmol/L)-HDL-C(mmol/L).The 95％reference interval(P25～P97 5)was calculated according to the percentile method recommended in WS/T402-2012 Health Industry Standard of the People's Republic of China.Multivariate logistic regression was used to analyze the influencing factors of serum n-HDL-C level.Results The serum n-HDL-C levels in both males and females were not normally distributed(S=2.119,2.091,all P＜0.001).There were significant differences in serum levels of n-HDL-C among males aged＞60 years old[2.98(2.50,3.37)mmol/L],18～30 years old[2.84(2.49,3.26)mmol/L],31～40 years old[2.98(2.62,3.42)mmol/L],41～50 years old[3.10(2.62,3.47)mmol/L]and 51～60 years old[3.05(2.64,3.46)mmol/L]contrast,and the differences were significant(H=3.618～5.680,all P＜0.05).There were significant differences in serum levels of n-HDL-C among women aged 51～60 years[3.08(2.71,3.44)mmol/L],18～30 years[2.64(2.29,3.07)mmol/L],31～40 years[2.67(2.31,3.08)mmol/L]and 41～50 years old[2.94(2.58,3.29)mmol/L]contrast(H=8.161～13.445,all P＜0.001).There were significant differences in serum n-HDL-C levels among patients aged＞60 years old[2.98(2.57,3.34)mmol/L],18～30 years old,31～40 years old and 41～50 years old contrast,and the differences were significant(H=7.985～14.018,all P＜0.001).The reference interval of serum n-HDL-C level in adult population was obtained by combining the age groups with no statistical significance:males aged 18～60 years old(1.97～3.97mmol/L),＞60 years old(1.86～3.91mmol/L);females aged 18～50 years(1.82～3.74 mmol/L),＞50 years old(1.94～3.88 mmol/L).A total of 16 921 adults were divided into normal n-HDL-C group and abnormal group,and the differences of serum TG(1.02±0.31 mmol/L vs 1.24±0.37mmol/L),TCHO(3.97±1.02 mmol/L vs 4.66±1.25 mmol/L),LDL-C(2.37±0.58mmol/L vs 2.59±0.67 mmol/L)levels and age(43.55±11.52 years vs 46.27±8.13 years)between the two groups were significant(t=2.041～3.151,all P＜0.05),in which the abnormal rate of serum n-HDL-C level was 42.50％.Multivariate Logistic regression analysis showed that males,lack of exercise,overweight or obesity,dyslipidemia,urban residents,and high school education or above were the influential factors for serum n-HDL-C levels in adults in this region(all P＜0.05).Conclusion The reference interval of serum n-HDL-C level in adults in this area was preliminarily established.Males,lack of exercise,overweight or obesity,dyslipidemia,urban residents,and high school education or above were the influential factors of abnormal serum n-HDL-C levels in adults in this area.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer and current therapeutic strategies are limited in their effectiveness.The expressions of Rab5 and the M2 tumor-associated macrophage marker CD163 in tissues were detected by Western blot. The migration and invasion of cells were determined using a Transwell assay. The expressions of the exosome markers were evaluated by Western blot. The polarization of human macrophages (THP-1) was determined by incubation of THP-1 cells with conditioned medium or exosomes collected from MDA-MB-231 cells with indicated transfections or by a coculture system of THP-1 and MDA-MB-231 cells. The M1 and M2 macrophage markers were evaluated by qRT-PCR. The expression of Rab5 in TNBC was significantly higher than that in normal breast tissue. Rab5 expressions in triple-negative and luminal A breast cancer were higher than those in other molecular subtypes. Higher CD163 expression was observed in triple-negative breast cancer and in triple-negative and luminal B subtypes. Rab5 knockdown suppressed but Rab5 overexpression promoted the migration and invasion capacity of MDA-MB-231 cells. The levels of CD63 and CD9 in the medium of Rab5 knockdown cells were lower than those in control cells, whereas higher levels of CD63 and CD9 were observed in Rab5 overexpression cells. Rab5 knockdown decreased the excretion but did not alter the diameter of the exosomes. Knockdown of Rab5 facilitated the anti-tumor polarization of macrophages, which was partially reversed by Rab5 overexpression. Therefore, Rab5 is expected to be a potential therapeutic target for triple-negative breast cancer.

OBJECTIVES: Liver cancer is the sixth most common malignant tumor in the world. Hepatocellular carcinoma (HCC) accounts for 85%-90% of all patients with liver cancer. It possesses the characteristics of insidious onset, rapid progression, early recurrence, easy drug resistance, and poor prognosis. NIMA related kinase 2 (NEK2) is a cell cycle regulating kinases, which regulates cell cycle in mitosis. Cellular senescence is a complex heterogeneous process, and is a stable form of cell cycle arrest that limits the proliferative potential of cells. This study aims to investigate the relationship between the expression level of NEK2 and the senescence in hepatoma cells, and to explore the effect of NEK2 expression on hepatoma cell senescence and the underlying molecular mechanism. METHODS: A total of 581 senescence-relevant genes were obtained from the GenAge website. The gene expression data of tumor tissues of 370 HCC patients were downloaded from the Cancer Genome Atlas database. The co-expression of NEK2 and aging-related genes was analyzed by R-package. KEGG was used to analyze the significant gene enrichment pathway of differentially expressed genes in NEK2 overexpression HEK293. The stable transfected cell lines with overexpression and knockdown of NEK2 were constructed in hepatoma cell line SMMC-7721 and HepG2, and senescence-associated β-galactosidase (SA-β-gal) staining was used to detect senescence, the cell proliferation was detected by CCK-8 method and clone formation experiment, the cell cycle was analyzed by flow cytometry, and the expression of proteins related to p53/p21, p16/Rb, and phosphatase and tensin homolog deleted on chromosome ten (PTEN)/Akt signal transduction pathway was detected by Western blotting. RESULTS: There were 320 senescence related genes co-expressed with NEK2. KEGG analysis showed that the senescence signaling pathway was significantly enriched in HEK293 cells with overexpression of NEK2.Compared with SMMC-7721 or HepG2 without knockdown of NEK2, the senescent cells of SMMC-7721 and HepG2 with knockdown of NEK2 were increased, cell proliferation and clone formation were decreased significantly, the percentage of cells in G₀/G₁ phase was increased, the expression levels of phospho-Akt (p-Akt) and phospho-Rb (p-Rb) protein were decreased significantly, and the expression level of p16 protein was increased significantly (all P<0.05). Compared with SMMC-7721 or HepG2 transfected with blank plasmid, the senescent cells of SMMC-7721 and HepG2 overexpressing NEK2 were decreased, the cell proliferation and clone formation were increased significantly, the percentage of cells in G₀/G₁ phase were decreased, the expression levels of p-Akt and p-Rb protein were increased significantly, and the expression level of p16 protein was decreased significantly (all P<0.05). CONCLUSIONS NEK2 may mediate the anti-aging effect of hepatoma cells through p16/Rb and PTEN/Akt signal transduction pathways, which provides a new theoretical basis for NEK2 to promote the progress of liver cancer and a new idea for the targeting treatment for liver cancer.

With accumulating dysregulated circular RNAs(circRNAs)in pathological processes,the regulatory functions of circRNAs,especially circRNAs as microRNA(miRNA)sponges and their interactions with RNA-binding proteins(RBPs),have been widely validated.However,the collected information on experimentally validated circRNA-disease associations is only preliminary.Therefore,an updated CircR2Disease database providing a comprehensive resource and web tool to clarify the relationships between circRNAs and diseases in diverse species is necessary.Here,we present an updated CircR2Disease v2.0 with the increased number of circRNA-disease associations and novel characteristics.CircR2Disease v2.0 provides more than 5-fold experimentally validated circRNA-disease associations compared to its previous version.This version includes 4201 entries between 3077 circRNAs and 312 disease subtypes.Secondly,the information of circRNA-miRNA,circRNA-miRNA-target,and circRNA-RBP interactions has been manually collected for various diseases.Thirdly,the gene symbols of circRNAs and disease name IDs can be linked with various nomenclature databases.Detailed descriptions such as samples and journals have also been integrated into the updated version.Thus,CircR2Disease v2.0 can serve as a platform for users to systematically investigate the roles of dysregulated circRNAs in various diseases and further explore the posttranscriptional regulatory function in diseases.Finally,we propose a computational method named circDis based on the graph convolutional network(GCN)and gradient boosting decision tree(GBDT)to illustrate the applications of the CircR2Disease v2.0 database.
