[Purpose]To analyze the trends of cervical cancer incidence in Qidong City of Jiangsu Province from 1977 to 2021.[Methods]Based on the cervical cancer registration database in Qi-dong City from 1977 to 2021,the crude incidence rate,the age-standardized rate by the standard Chinese standard population and the world standard population(ASRC and ASRW),the truncated rate of 35～64 years old,the cumulative rate of 0～74 years old,and the cumulative risk were cal-culated;the incidence rates of birth cohorts were analyzed.Joinpoint regression analysis was per-formed with Joinpoint 4.9.0.0 software to calculate the annual percentage change(APC)and the average annual percentage change(AAPC)of cervical cancer incidence.[Results]A total of 2 253 new cases of cervical cancer registered in Qidong City from 1977 to 2021,accounting for 1.62％of the total case numbers of cancer in the whole population,and for 4.03％of the total number of cancers in women.The crude incidence rate was 8.75/105,the ASRC was 4.54/105,the ASRW was 6.01/105,the truncated rate(35～64 years old)was 15.09/105,the cumulative rate(0～74 years old)was 0.63％,and the cumulative risk was 0.63％.The incidence of cervical cancer increased with age from 1977 to 2021.The average incident age was 55.36 years old,with the lowest age of 47.51 years old in 2010.Secular trend analysis showed that the AAPC of the crude incidence of cervical cancer was 6.010％(95％CI:4.951％～7.081％)(P＜0.001),among which the trend decreased from 1977 to 1999,with an APC of-2.507％;and then the trend increased from 1999 to 2017,with an APC of 14.436％(P＜0.001).The rising and falling trend curves of the AS-RC and ASRW were similar to that of the crude incidence.The age group and time period analysis showed that the peak incidence was in the older age groups before 2006,while the peak inci-dence appeared in the age groups of 45～54 years old from 2007 to 2021.The AAPCs in age groups of 25～64 years old demonstrated upward trends(all P＜0.05).The birth cohort analysis showed that the cervical cancer incidence in the 1937-1941 birth cohort was the lowest,and the birth cohort-specific rates in all age groups showed"V-shape"trends.[Conclusion]Long-term monitoring of cervical cancer incidence in Qidong has shown a trend of initially slow decline fol-lowed by a rapid increase,with the peak incident shifting towards younger ages.The rising trends of cervical cancer incidence in last two decades may be associated with the increased HPV infection,suggesting that measures to reduce HPV infection and enhance vaccination should be strengthened.

Objective:To analyze the trend of ovarian cancer incidence in Qidong City from 1972 to 2021 and evaluate the age, period, and cohort effect.Methods:The ovarian cancer incidence data from 1972 to 2021 were extracted from the Qidong Cancer Registry Database, the crude incidence rate (CR), age standardized rate by Chinese population (ASR-C), age standardized rate by world population (ASR-W), and average annual percent change (AAPC) were calculated. The age-period-cohort model was used to analyze the age, period, and birth cohort effects of the ovarian cancer incidence in Qidong from 1972 to 2021.Results:From 1972 to 2021, a total of 1 007 cases of ovarian cancer occurred in Qidong. The AAPC values of CR, ASR-C, and ASR-W were 7.02% , 5.17%, and 5.12% , respectively (all P＜0.001). The time trends showed that, the AAPC values of the age groups of 0-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 4.10%, 4.74%, 6.02%, 4.86%, 4.23%, and 5.18%, respectively (all P＜0.05). The age effect showed that the incidence rate of ovarian cancer increased obviously from the 45-49 year-old group, reaching a peak of 20.67/100 000 in the 75-79 year-old group. Compared with the 1992-1996 group, the period of 2002-2021 had significant effects on the incidence rise of ovarian cancer (all P＜0.05), and the incidence rate ratio ( RR) increased with the period: in 2017-2021 the RR was 3.86 (95% CI: 2.72-5.47). Using births from 1952 to 1956 as the reference group, the RR increased slowly from 0.12 (95% CI: 0.02-0.91) in 1892-1896, and peaked in 2007-2011 with an RR of 18.05 (95% CI: 3.51-92.87). The birth cohorts in 1967-2011 had significant effects on the incidence rise of ovarian cancer (all P＜0.05). The Waldχ 2 test of the age-period-cohort model showed that there were significant differences in the age, period, and birth cohort effects (all P＜0.001). Conclusions:The incidence of ovarian cancer in Qidong was on the rise. Age, period, and cohort were the main factors affecting the incidence of ovarian cancer. The middle-aged and elderly women were the focus of ovarian cancer prevention and control.

Objectives:To evaluate the hemodynamic impact of different bypass grafting methods on the left anterior descending(LAD)artery using computational fluid dynamics,providing a theoretical basis for optimizing coronary artery bypass grafting.Methods:A patient-specific 3D coronary model was constructed using SimVascular software,including an in-situ internal mammary artery graft(model 1)and three free grafts of varying diameters(model 2:2 mm internal mammary artery free graft;model 3 and model 4:3 mm and 4 mm great saphenous vein free grafts).The hemodynamic parameters of the native artery and grafts were compared among the four bypass grafting models.Results:All four bypass grafting models supply sufficient blood flow for the severely stenosed LAD.LAD flow was slightly lower in the model 1.Free internal mammary artery grafts showed higher flow and wall shear stress.4 mm great saphenous vein free grafts presented with maximum flow but lowest shear stress,3 mm great saphenous vein free grafts offered better hemodynamic stability.Conclusions:Computational fluid dynamics analysis indicates that free internal mammary grafts could provide superior hemodynamics,while larger grafts result in lower shear stress,which might affect long-term graft patency.These findings thus provide experimental evidences useful for optimizing LAD bypass strategies.

Exosome, as the critical communication carrier secreted by cells, has been demonstrated to carry non-coding RNA (ncRNA) that participate in regulating the onset and progression of various female reproductive system diseases. In this review, the roles of exosome ncRNA (such as microRNA, long ncRNA, and circular RNA) in non-tumor diseases of the female reproductive system were reviewed, including premature ovarian failure, polycystic ovary syndrome, and endometriosis, as well as in female reproductive system tumor diseases such as ovarian cancer, cervical cancer, and endometrial cancer. The theoretical basis and broad application prospects for the development of non-invasive diagnostic markers, prognostic evaluation tools, and potential therapeutic targets based on exosome ncRNA were provided.

Viruses constitute a significant group of pathogens that have caused numerous fatalities and substantial economic losses in recent years, particularly with the emergence of coronaviruses. While the impact of SARS-CoV-2 appears to be diminishing in daily life, only a limited number of drugs have received approval or emergency use authorization for its treatment. Given the high mutation rate of viral genomes, host-directed agents (HDAs) have emerged as a preferred choice due to their broad applicability and lasting effectiveness. In contrast to direct-acting antivirals (DAAs), HDAs offer several advantages, including broad-spectrum antiviral activities, potential efficacy against future emerging viruses, and a lower likelihood of inducing drug resistance. In our review article, we have synthesized known host-directed antiviral targets that span diverse cellular pathways and mechanisms, shedding light on the intricate interplay between host cells and viruses. Additionally, we have provided a brief overview of the development of HDAs based on these targets. We aim for this comprehensive analysis to offer valuable perspectives and insights that can guide future antiviral research and drug development efforts.

A chemical investigation of secondary metabolites (SMs) from Aspergillus nidulans resulted in the identification of five novel dioxopiperazine (DKP)-diphenyl ether hybrids, designated as diphenylemestrins A-E (1-5). These compounds 1-5 represent the first known dimers combining DKP and diphenyl ether structures, with compound 4 featuring an uncommon dibenzofuran as the diphenyl ether component. The structural elucidation and determination of absolute stereochemistry were accomplished through spectroscopic analysis and electronic circular dichroism (ECD) calculations. Notably, diphenylemestrin C (3) exhibited moderate cytostatic activity against NB4 cells, with a half maximal inhibitory concentration (IC₅₀) value of 21.99 μmol·L^-1, and induced apoptosis at higher concentrations.

(±)-Talapyrones A-F (1-6), six pairs of dimeric polyketide enantiomers featuring unusual 6/6/6 and 6/6/6/5 ring systems, were isolated from the fungus Talaromyces adpressus. Their structures were determined by spectroscopic analysis and HR-ESI-MS data, and their absolute configurations were elucidated using a modified Mosher's method and electronic circular dichroism (ECD) calculations. (±)-Talapyrones A-F (1-6) possess a 6/6/6 tricyclic skeleton, presumably formed through a Michael addition reaction between one molecule of α-pyrone derivative and one molecule of C₈ poly-β-keto chain. In addition, compounds 2/3 and 4/5 are two pairs of C-18 epimers, respectively. Putative biosynthetic pathways of 1-6 were discussed.
