Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Aim To investigate the effects of tran-scription factor FoxO1 on acute kidney injury(AKI)induced by ischemic reperfusion injury(IRI)and to explore the underlying mechanisms.Methods Male C57BL/6 mice were randomly divided into four groups:Sham,IRI,FoxO1 inducible cell-specific knockout(FoxO1 icKO),and IRI+FoxO1 icKO.Tamoxifen(25 mg·kg-1)was intraperitoneally injec-ted to specifically knock out FoxO1 in mouse macro-phages,and a unilateral renal IRI model was estab-lished.The levels of serum creatinine(Scr),blood u-rea nitrogen(BUN),Fe2+,malondialdehyde(MDA),reactive oxygen species(ROS),and reduced glutathi-one(GSH)in renal tissues were detected.Hematoxy-lin-eosin(HE)staining was used to observe the patho-logical changes in renal tissues.Quantitative polymer-ase chain reaction(qPCR)was used to detect the mR-NA levels of inflammatory factors such as IL-1β and MCP1 in renal tissues.Western blot was used to detect the expression levels of apoptosis and ferroptosis-relat-ed proteins.Results Compared with the control group,the levels of Scr and BUN in the IRI group were significantly upregulated,the infiltration of inflammato-ry factors IL-1β,TNF-α and MCP1 increased,the pro-tein expressions of Bax/Bc12,cleaved-caspase-3/caspase-3,cytochrome C,and FTH1 in renal tissues were significantly enhanced,while the expression of GPX4 decreased.In addition,the levels of Fe2+,MDA and ROS in the renal cortex of the IRI group signifi-cantly increased,and the level of GSH markedly de-creased(P＜0.05).Compared with the IRI group,the levels of Scr and BUN in the FoxO1 icKO group were significantly reduced,the infiltration of inflammatory factors was alleviated,the expression of apoptosis-relat-ed proteins in renal tissue decreased,the expression level of ferroptosis protein GPX4 increased,and the ex-pression of FTH1 decreased.The levels of Fe2+,MDA and ROS in the renal cortex decreased,and the level of GSH significantly increased(P＜0.05).Conclusion Inducing the specific knockout of FoxO1 in macro-phages can alleviate AKI induced by IRI,and its mech-anism may be related to the inhibition of ferroptosis caused by IRI by FoxO1.

OBJECTIVE To conduct a literature review of one case of follicular lymphoma complicated with iliac bone Cryptococcus neoformans infection so as to raise the understanding of such pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.METHODS The clinical data were collected from one case of follicular lymphoma patient complicated with C.neoformans infection who was treated in Xinrui Hospital of Xin-wu District,Wuxi City on Feb.24,2023 and retrospectively analyzed.All of relevant literatures regarding to the subject were retrieved in Pubmed,CNKI,Wanfang and VIP databases,and the clinical data of the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma with C.neoformans infection were screened out and summa-rized.RESULTS The case was a 28-year-old male and had the underlying disease of follicular lymphoma.The C.neoformans was detected by iliac bone histopathology and metagenome next generation sequencing(mNGS).The condition of the patient improved after the treatment with amphotericin B cholesterol sulphate com-pound and fluconazole.A total of 28 patients,with this case included,were involved in the literature review,23 of whom were male,and 5 were female,and the age ranged between 16 and 79 years old.With respect to major in-fection sites,there were 15(53.57％)cases of cerebral infection,9(32.14％)cases of blood infections,7(25.00％)cases of pulmonary infection,4(14.285％)cases of skin infections,2(7.14％)cases of muscle tis-sue infections,2(7.14％)cases of pleural effusion infections,2(7.14％)cases of bone infections and 1(3.57％)case of bone marrow infection.Totally 11 patients had disseminated Cryptococcus infection,accounting for 39.28％.CONCLUSIONS The C.neoformans infection is seldom detected in the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma.The brain is the major infection site with the high probability of dissemina-ted infection.It is necessary for the hospital to deepen the understanding of the pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.

In recent years, the situation of climate change has intensified, posing a threat to public health. There is an urgent need to promote public health adaptation actions to climate change. In January 2025, the National Disease Control and Prevention Administration issued the "Guidelines for Public Health Adaptation Actions to Climate Change" (hereinafter referred to as the "Guidelines"). The Guidelines put forward 20 items of guidance on six categories of public health adaptation actions, including understanding basic concepts, comprehending important policies, learning core knowledge, paying attention to key populations, practicing a low-carbon lifestyle, and mastering protection skills. It elaborates on the key concepts and the latest policies that the public needs to understand, and also provides the behavioral concepts and protection skills that should be mastered to adapt to climate change. This article provides a systematic interpretation of the Guidelines, introducing the background, ideas, connotations, and applications of their compilation, with the aim of enhancing society′s cognitive understanding of the Guidelines.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

With the continuous rise in the incidence of cardiovascular disease (CVD) and the prolongation of life expectancy of patients living with the disease, improving the quality of life of patients has become an important management goal. Sexual life, as a basic physiological need in human survival, is also a key component of the quality of life for CVD patients. However, due to the impact of the disease, sexual health issues are common among CVD patients and have adverse effects on their quality of life, mental health, and marital relationships, which should be addressed promptly. This article reviews the definitions related to sexual health, the current research on sexual health in CVD patients, research tools related to sexual health, influencing factors of sexual health in CVD patients, and sexual health interventions, aiming to provide a reference for clinical research in this area.

Objective:To investigate the vaccination rate of 23-valent pneumococcal polysaccharide vaccine (PPV23), identify determinants of vaccination willingness, and analyze barriers to vaccination among community-dwelling elderly in Xinzhuang Town of Shanghai Minhang District.Methods:This cross-sectional study was conducted in Xinzhuang Town of Shanghai Minhang District from November to December 2024. An online questionnaire was distributed via WeChat groups of neighborhood committees to community-dwelling elderly (aged≥60 years) using a convenience sampling method. The questionnaire covered basic demographic information, health status, knowledge and awareness about pneumonia and PPV23, attitudes toward PPV23 vaccination, and vaccination behavior. The χ2 test and multivariate logistic regression analysis were employed to identify factors influencing the PPV23 vaccination rate and willingness to vaccination among the elderly. Results:A total of 667 questionnaires were collected and 612 were valid (91.8%). Among 612 responders there were 223 males (36.44%) and 389 females (63.56%), and 304 (49.67%) aged 70-79 years. In all respondents, 185 (30.23%) had previously received PPV23, while 427 (69.77%) had not. Reasons for non-vaccination included unawareness of vaccine necessity (31.85%, 136/427), self-perceived good health (31.15%, 133/427), concerns about adverse reactions (21.08%, 90/427), and lack of physician recommendation (14.52%, 62/427). In all participants, 65.85%(403/612)expressed willingness for vaccination and 34.15%(209/612) did not have willingness. Factors significantly influencing vaccination willingness included negative perception of vaccine efficacy ( OR=2.750, 95% CI:1.077-7.023), concerns about adverse reactions ( OR=2.568, 95% CI:1.258-5.242), low awareness of pneumonia and PPV23 vaccine ( OR=11.608, 95% CI:4.177-32.258), perceived vaccination inconvenience ( OR=0.457, 95% CI:0.248-0.844), and belief in good health negating need ( OR=2.658, 95% CI:1.361-5.190) (all P<0.05). Conclusions:Suboptimal PPV23 vaccination rates and low willingness among community-dwelling elderly in Shanghai Xinzhuang Town are driven by knowledge gaps and perceptual barriers. Targeted interventions should prioritize physician engagement, accessible vaccination services, and public education addressing safety and efficacy concerns.
