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.

[Purpose]To analyze the trends in incidence,mortality and potential life loss of esophageal cancer in Linzhou City of Henan Province from 2010 to 2019.[Methods]The data of esophageal cancer incidence and mortality from 2010 to 2019 were collected from Linzhou cancer registries.The crude incidence and mortality rates,age-standardized rates(ASR)by sex and age group,the potential years of life lost(PYLL),average potential years of life lost(APYLL),and potential years of life lost rate(PYLLR)were calculated.The average annual percentage change(AAPC)from 2010 to 2019 were analyzed with Joinpoint software.[Results]From 2010 to 2019,there were a total of 8 447 newly diagnosed cases and 6 475 deaths of esophageal cancer in Linzhou.The ASR incidence and ASR mortality of esophageal cancer in the total population,males,females all showed significant downward trends,with AAPCs of-3.97％,-4.35％,-3.29％and-3.78％,-2.68％,-4.95％,respectively(all P＜0.05).The crude incidence and mortality rates in all age groups also showed significant downward trends.The AAPCs of incidence rate for the age groups of 0～49,50～59,60～69,and ≥70 years old were-9.92％,-8.27％,-1.41％,and-3.86％,respectively(all P＜0.05),and the AAPCs of mortality rate were-950％,-12.36％,-2.61％,and-2.98％,respectively(all P＜0.05).From 2010 to 2019,the total PYLL caused by esophageal cancer was 60 880 person years,APYLL was 13.73 person years,and PYLLR was 5.77‰.The PYLL,APYLL,and the PYLLR of the total population and those stratified by sex all showed a decreasing trend(all P＜0.05).[Con-clusion]From 2010 to 2019,the incidence,mortality and potential life loss of esophageal cancer in Linzhou City all decreased,and the long-term effect and screening programs is significant.How-ever,the risk of esophageal cancer among men and the elderly is still relatively high,indicating that more targeted prevention and control strategies should be developed.

[Purpose]To analyze the trends of incidence and mortality of malignant tumors in Linzhou City of Henan Province from 2010 to 2019.[Methods]The incidence and mortality data of malignant tumors of Linzhou cancer registration areas from 2010 to 2019 were collected and evaluated for data quality.The crude incidence/mortality rates and age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC)were calculated by sex,age and can-cer type.Joinpoint software was used to calculate the average annual percentage change(AAPC)to analyze the trends from 2010 to 2019.[Results]From 2010 to 2019,the crude incidence of malig-nant tumors in Linzhou City showed an upward trend,with an AAPC of 2.09％(95％CI:0.58％～3.63％),while the ASIRC tended to be stable.The incidence of malignant tumors showed a signifi-cant upward trend in the 15～29 and 60～69 age groups,and a significant downward trend in the 70～79 age group.From 2010 to 2019,the ASIRC of esophageal cancer and stomach cancer in both men and women showed a significant downward trend,while that of lung cancer and prostate cancer increased in men,and the incidences of thyroid cancer,uterus cancer,cervical cancer,lung cancer and breast cancer increased significantly in women.From 2010 to 2019,the crude mortality of malignant tumors in Linzhou showed a significant upward trend,with an AAPC of 1.18％(95％CI:0.88％～1.48％),while ASMRC showed a significant downward trend,with an AAPC of-1.63％(95％CI:-1.86％～-1.40％).The mortality increased in the group aged 80 and above,while the other age groups remained in a downward or stable state.From 2010 to 2019,the ASMRC of stomach cancer and esophageal cancer in both men and women showed a down-ward trend,while those of prostate cancer,and malignant tumors of the lip,oral cavity and pha-ryngeal in men increased,and that of ovarian cancer in women increased significantly.[Conclu-sion]The disease burden of malignant tumors in Linzhou City is still heavy.The incidence of common cancer types such as thyroid cancer,prostate cancer and lung cancer shows a significant-ly increasing trends from 2010 to 2019.

Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.

Objective:To explore the effect of long noncoding RNA ANK3DT (lncRNA ANK3DT) on DNA damage repair ability and radiosensitivity of cervical cancer HeLa cells.Methods:The effect of lncRNA ANK3DT on the repair efficiency of DNA double-strand breaks (DSBs) was analyzed by the pre-constructed quantitative assay system based on the CRISPR/Cas9 system targeting homologous recombination (HR) and non-homologous end-joining (NHEJ) repair. Clone formation assay, flow cytometry, and immunofluorescence were used to detect the effects of down-regulation of lncRNA ANK3DT on cellular radiosensitivity, apoptosis and G 2/M phase arrest, and DSB repair after X-ray irradiation. Western blot, qPCR, and dual fluorokinase reporter gene plasmid was used to detect the effects of lncRNA ANK3DT on the HR repair-related protein CtIP expression and transcriptional regulation. Results:Down-regulation of lncRNA ANK3DT significantly inhibited HR repair and had no effect on NHEJ repair. The expression of lncRNA ANK3DT was significantly increased in HeLa cells at 24, 48, 72 h after X-ray irradiation ( t=-23.39, -88.83, -52.42, P<0.05). Down-regulation of lncRNA ANK3DT inhibited X-ray-induced DSB repair and increased apoptosis levels ( t=-14.63, P <0.05), prolonged G 2/M phase block ( t=-19.50, P <0.05), increased the radiosensitivity of HeLa cells (radiosensitization ratio=1.21), inhibited the CtIP promoter activity and decreased its mRNA and protein expression. Conclusions:lncRNA ANK3DT affects HR repair by regulating CtIP transcription, and down-regulation of lncRNA ANK3DT increases the radiosensitivity of HeLa cells by inhibiting DSB repair after ionizing radiation.
