Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

Generative artificial intelligence (GAI) represents a prominent research focus in medicine, with medical education being a key application area. GAI demonstrates potential to enhance residency training efficacy through personalized instruction, automated assessment item generation, question bank updating, and intelligent scoring systems. However, current limitations exist regarding output accuracy and content consistency. To address these constraints, strategic measures are required: continuous GAI model refinement, development of standardized usage guidelines, enhanced data quality control, and implementation of human verification protocols for generated content. Concurrently, residents should proactively acquire GAI utilization skills to strengthen the practical application of theoretical knowledge. With these advancements, GAI is anticipated to evolve into a valuable asset for improving the efficiency and quality of residency training programs.

Objective: To investigate the trend in incidence and change in age at onset of lung cancer in in Wujiang District, Suzhou City, Jiangsu Province from 2012 to 2021, so as to provide a basis for strengthening targeted prevention and control of lung cancer. Methods: Data of lung cancer incidence from 2012 to 2021 were collected through the Wujiang District Tumor Follow-up Registration Information System. The crude incidence, truncated incidence for 35 to 64 years, and cumulative incidence for 0 to 74 years were calculated. Chinese population-standardized incidence, Chinese population-standardized average age at onset, and Chinese population-standardized incidence proportion were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. The trend in incidence of lung cancer from 2012 to 2021 was evaluated using average annual percent change (AAPC). The trend in the Chinese population-standardized average age at onset of lung cancer from 2012 to 2021 was evaluated using a linear regression model. Results: From 2012 to 2021, the crude incidence, the Chinese population-standardized incidence and truncated incidence for 35 to 64 years of lung cancer in Wujiang District were 84.57/100 000, 37.28/100 000 and 52.10/100 000, respectively, all showing upward trends (AAPC=2.489%, 2.034% and 4.654%, all P<0.05). The cumulative incidence for 0 to 74 years was 4.48%, showing no significant trend (P>0.05). The Chinese population-standardized incidence was higher in males than in females (48.16/105 vs. 26.81/105). The Chinese population-standardized incidence of lung cancer in females showed an upward trend (AAPC=8.174%, P<0.05), while the trend in males was not statistically significant (P>0.05). The crude incidence of lung cancer showed upward trends in the total population and females aged 0-<45 years (AAPC=18.287% and 25.343%, both P<0.05) and those aged 45-<55 age group (AAPC=8.003% and 17.629%, both P<0.05). The Chinese population-standardized average age at onset of lung cancer in total population and females decreased from 67.58 and 65.48 years in 2012 to 60.15 and 54.88 years in 2021, with an average annual reduction of 0.611 and 0.964 years, respectively (both P<0.05). The Chinese population-standardized incidence proportion showed upward trends for the total population and females under 65 years (AAPC=3.879% and 4.639%, both P<0.05). No statistically significant trends were observed in the Chinese population-standardized average age at onset or incidence proportion in males (both P>0.05). Conclusions From 2012 to 2021, the incidence of lung cancer in Wujiang District showed an increasing trend and a trend toward younger onset age. Young and middle-aged females had emerged as a key target population for lung cancer prevention and control.

BACKGROUND: Doxorubicin hydrochloride (DOX) is extensively used in the treatment of various tumors. However, its clinical application is limited due to dose-dependent cardiotoxicity. Currently, few effective strategies exist to mitigate or eliminate DOX-induced cardiomyopathy (DIC). Although ferroptosis is implicated in DIC and its inhibition partially alleviates the condition, the direct targets of DOX in the progression of cardiotoxicity remain unclear. This study aimed to discover the direct targets of DOX in ferroptosis-mediated DIC. METHODS: A DOX pulldown assay was performed to identify proteins specifically binding to DOX in murine hearts, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify candidate proteins. A cardiac injury mouse model was established by DOX treatment. Based on this, multiple ferroptosis biomarkers were detected by flow cytometry, quantitative real-time polymerase chain reaction, western blotting, immunochemistry, etc. Besides, specific activator and inhibitor of signaling pathways were applied to illuminate molecular mechanisms. RESULTS: Glutathione S-transferase P1 (GSTP1) was identified as a DOX target. GSTP1 activity was inhibited in DOX-treated cardiomyocytes, while its overexpression significantly alleviated DIC. Moreover, GSTP1 overexpression inhibited acyl-CoA synthetase long-chain family member 4 (ACSL4)-dependent ferroptosis. Mechanistically, GSTP1 overexpression suppressed c-Jun N-terminal kinase (JNK) phosphorylation, thereby reducing reactive oxygen species (ROS) production and inhibiting ferroptosis in DIC. CONCLUSIONS This study identifies the DOX/GSTP1/JNK axis as a critical pathway mediating ACSL4-dependent ferroptosis in DIC. GSTP1 is highlighted as a potential key mediator of ferroptosis and a promising therapeutic target for DIC.

OBJECTIVES: To explore the mechanism through which moxibustion promotes endometrial repair in rats with in thin endometrium (TE). METHODS: Female SD rats were randomized into control group, 95% anhydrous ethanol-induced TE model group and moxibustion (at "Guan Yuan") group. High-throughput sequencing was used to identify the target genes of TE, and the targeting relationship between miR-223-3p and NLRP3 was verified using a dual luciferase assay. Histopathological of rat uterus was observed with HE staining, and expressions of miR-223-3p and NLRP3 were detected using RT-qPCR; serum levels of IL-1β and IL-18 of the rats were detected using ELISA, and protein expressions of NLRP3, ASC, caspase-1 and GSDMD in the uterus were detected with Western blotting. The pregnancies of the rats after treatment were counted. RESULTS: Enrichment analysis of the differential genes suggested up-regulated inflammatory response in TE, and dual luciferase assay verified targeted inhibition of NLRP3 expression by miR-223-3p. The rat models of TE had significantly decreased endometrial thickness and reduced endometrial glands and blood vessels with enhanced mRNA expression of NLRP3, increased serum levels of IL-1β and IL-18, up-regulated protein expressions of NLRP3, ASC, caspase-1 and GSDMD, lowered pregnancy rates on both the affected and unaffected sides and the overall number of pregnancies. Treatment of the rat models with mo-xibustion obviously increased the endometrial thickness and the density of glands and blood vessels, up-regulated miR-223-3p expression, lowered serum IL-1β and IL-18 levels and the protein expressions of NLRP3, ASC, caspase-1 and GSDMD, and significantly increased the number of pregnancies. CONCLUSIONS Moxibustion at "Guan Yuan" acupoint up-regulates the expression of miR-223-3p, which results in targeted inhibition of NLRP3 to suppress pyroptosis and promote endometrial repair in rat models of TE.

Objective: To understand cumulative health risk behaviors among college students and the association with adverse childhood experiences, so as to provide a theoretical basis for the prevention and control of health risk behaviors in this population. Methods: From November to December 2022, four universities in Shanghai were selected using convenience sampling, and 3 039 students were selected for a questionnaire survey using random cluster sampling. The questionnaire covered general basic information, adverse childhood experiences and health risk behaviors. A latent class analysis was carried out to explore the latent classes of health risk behaviors among the college students and multivariate Logistic regression was performed to analyze the association between adverse childhood experiences and cumulative health risk behaviors. Results: The health risk behaviors of college students were classified into three latent classes:a low risk group (84.60%), a high risk group for smoking and alcohol consumption ( 10.37 %), and an excessive sugar intake group (5.03%). The proportion of three latent classes of health risk behaviors varied significantly by childhood neglect and abuse, family functioning and other adverse childhood experiences ( χ 2=210.67, 106.55, 104.41 , P <0.01). The results of the multiple Logistic regression analysis revealed that childhood neglect and abuse, poor family functioning, and other adversities increased the risk in the high risk group for smoking and alcohol consumption among college students ( OR =6.24, 3.80, 3.68), as well as an childhood neglect and abuse increased the risk of the excessive sugar intake group among college students ( OR =2.18) ( P <0.01). Conclusions Adverse childhood experiences are associated with clustered health risk behaviors. Proactive measures should be taken to prevent the transmission of negative childhood experiences, which would contribute to reduce the occurrence of health risk behaviors among college students.

Objective To investigate the expression of N6 methyladenine(m6A)demethylase human fat mass and obesity-associated(FTO)protein in nasopharyngeal carcinoma(NPC),and the effect of over-expression of FTO on the proliferation of nasopharyngeal carcinoma in vitro and in vivo.Methods Immunohistochemistry method was used to detect the expression of FTO protein in nasopharyngeal carcinoma tissues and para-cancerous tissues;The dominant expression cell line of FTO was screened,the over-expression FTO cell line was constructed.The cell pro-liferation was examined by soft-agar method.A mouse tumor model was developed for measurement of tumor growth.ResultsThe expression of FTO in nasopharyngeal carcinoma tissues was lower than that in adjacent tissues.Low ex-pression of FTO promoted proliferation of NPC cells,while over-expression of FTO reversed this effect.Conclusions FTO inhibits proliferation of nasopharyngeal carcinoma and this result may provide an experimental technology in searching therapeutic targets of chemotherapy for nasopharyngeal carcinoma.

Objective To identify the causative variants in 5 Chinese families with tuberous sclerosis complex(TSC)to provide genetic counseling and prenatal diagnosis.Methods Genetic counseling and clinical diagnosis were performed in 8 patients from five unrelated TSC families by teleconsultation.With informed consent obtained from the participants,3 to 5 mL peripheral blood samples were collected from the probands and their family mem-bers for the extraction of genomic DNA.Candidate pathogenic variants were screened by panel sequencing(PS).The candidate pathogenic variants found in TSC1 and TSC2 by PS were validated by PCR-Sanger sequencing and bioinformatics analysis.Results All the pathogenic mutations were identified in the probands and their available family members.Causative variants in TSC1 or TSC2 were detected in all patients,including three reported variants and two novel variants.The two novel variants,TSC2:c.245G＞A and TSC2:c.235delG,which were predicted to cause the nonsense variant p.(Trp82?)and the frameshift variant p.(Val79Lysfs27?)respectively was believed to introduce premature stop codons.The analysis of family co-segregation and bioinformatics were identified as very positive factors for pathogenicity.Conclusions This result provides more evidences for the genetic counseling and prenatal diagnosis in these families and expand the spectrum of TSC2 pathogenic variants.
