Aging has emerged as a cutting edge and hotspot in global life science field， with anti-aging and geriatric disease prevention and treatment becoming critical issues urgently demanding solutions in international medical communities. In the face of the challenge of accelerating global population aging， in-depth exploration of aging mechanisms and the development of effective intervention strategies hold significant scientific and clinical value. This study supported by the national key research and development program of China， employed the essence-Qi-spirit theory of Qiluo doctrine as its guiding framework， focusing on the key scientific issue of the core traditional Chinese pathogenesis of aging， namely "depletion of kidney essence， deficiency of primordial Qi， and impairment of body and spirit". The treatment principle of "tonifying the kidney to replenish essence， harmonizing Yin and Yang， warming and invigorating primordial Qi， and nourishing the body and spirit" was established. Centered on holistic aging， systemic aging， and aging-related diseases， the research integrated multidisciplinary research approaches to construct multi-modal aging models and a multi-dimensional evaluation system， and it utilized multi-omics technologies to deeply analyze aging mechanisms. By systematically reviewing historical kidney-tonifying and anti-aging formulas and combining big data with artificial intelligence technologies， an information database of anti-aging traditional Chinese medicine substance was developed to reveal the differences and synergistic effects of various treatment methods and formulas on anti-aging. Based on this treatment method， the research integrated two millennia of kidney-tonifying medicinal experience to develop the innovative anti-aging traditional Chinese medicine， namely Bazhi Bushen capsules. It was validated that this capsule can delay holistic and systemic aging through multiple targets and mechanisms， thereby elucidating the scientific connotation of the essence-Qi-spirit theory of Qiluo doctrine in guiding anti-aging research from multiple dimensions and providing robust support for leveraging the advantages of traditional Chinese medicine to occupy the commanding heights of international anti-aging research.

Crawling-type adenocarcinoma (CTAC) is being increasingly recognized as a distinct histological subtype of early gastric cancer (EGC), characterized by irregularly fused glands with superficially bland cytologic atypia and a propensity for extensive lateral intramucosal spread.Although CTAC often mimics nonneoplastic lesions such as intestinal metaplasia, its biological behavior differs substantially from other differentiated-type adenocarcinomas. Notably, when CTAC invades the submucosa, the invasive component often exhibits a poorly differentiated or poorly cohesive carcinoma morphology. Thus, CTAC poses substantial challenges in accurate preoperative diagnosis, margin delineation, and complete removal during endoscopic submucosal dissection. This review synthesizes available evidence regarding the morphological, molecular, and clinical features of CTAC, emphasizing diagnostic challenges and the clinical implications of its “crawling” lateral growth pattern. It also highlights future directions, including the need for standardized diagnostic criteria and the development of CTAC-specific risk prediction tools for optimizing endoscopic resection.

AIM:To explore the protective effect of total flavonoids from rhododendron(TFR)on oxi-dative stress injury in the brain of rats subjected to cerebral ischemia/reperfusion(I/R).METHODS:For-ty male SD rats were randomly divided into 5 groups:sham operation group(Sham group),cere-bral ischemia-reperfusion group(MCAO group),and Cerebral Ischemia/Reperfusion with TFR treat-ment groups(TFR 50,100,200 mg/kg groups).The MCAO group and TFR-treated groups underwent ischemia/reperfusion surgery,and the TFR-treated groups received TFR intragastrically for 14 consecu-tive days following the ischemia/reperfusion injury.After 14 days,comparisons were made in terms of neurological function scores,serum inflammatory factors,oxidative stress indicators,and brain injury markers.Additionally,histological examination of brain tissue morphology using Hematoxylin and Eo-sin(HE)staining,observation of cerebral blood flow through cerebral blood flow imaging,and measurement of lactate dehydrogenase(LDH),neu-ron-specific enolase(NSE)activity in serum,inter-leukin-1(IL-1),interleukin-6(IL-6)levels,superox-ide dismutase(SOD)activity,malondialdehyde(MDA)content,nitric oxide(NO)content,and nitric oxide synthase(NOS)activity were performed.RE-SULTS:Compared to the Sham group,MCAO rats exhibited abnormal neurological function scores,severe damage to the microstructure of brain tis-sue,noticeable changes in brain morphology,ele-vated activities of LDH and NSE,increased levels of IL-1 and IL-6,elevated MDA content,and de-creased SOD,NOS activity,and NO content.In com-parison to the MCAO group,rats treated with TFR at doses of 50,100,and 200 mg/kg showed recov-ery of abnormal neurological function scores,re-duced damage to the microstructure of brain tis-sue,decreased activities of LDH and NSE,lowered levels of IL-1 and IL-6,reduced MDA content,and increased SOD,NOS activity,and NO content.CON-CLUSION:Total flavonoids from Rhododendron can protect against cerebral ischemia/reperfusion inju-ry,reducing oxidative stress levels.

Objective:To examine the near-complete genomic analysis of norovirus (NoV) subtype GⅡ.17 [P17] outbreaks in Beijing Chaoyang District from 2014 to 2024.Methods:Data and specimens related to outbreaks of the NoV aggregation in Beijing′s Chaoyang District from 2014 to 2024 were collected. The NoV was identified using real-time fluorescence reverse transcription polymerase chain reaction (RT-PCR). Specimens with positive nucleic acid were amplified by standard PCR, whole genome sequencing and evolutionary analysis. Amino acid site variations were compared.Results:In Chaoyang District, from 2014 to 2024, a total of 637 aggregated outbreaks caused by the NoV infection were reported, of which 584 were successfully typed. The epidemic caused by the GⅡ.17 [P17] subtype accounted for 8.79% (56/637), which was the dominant epidemic gene subtype in 2014-2015, sporadic in 2016-2019, reappeared in 2022, and significantly increased in 2024 (27.27%, 24/88). Outbreaks caused by the GⅡ.17 [P17] subtype occurred mainly from October to December, with the main sites of occurrence in primary schools and kindergartens. This study yielded 53 near-complete genome sequences of the GⅡ.17 [P17] subtype from 46 incidents in Chaoyang District. The GⅡ.17 [P17] subtype sequences of Chaoyang District from 2014 to 2024 were segmented into three subgroups on the evolutionary tree, with sequences from 2014 to 2019, 2022 to April 2024, and May to December 2024 clustered into the d, e, and b subgroups, respectively. In the VP1 region′s P2 area, particularly at the HBGA binding site, subgroups b and e exhibited mutations in 22 and two sites, while subgroups b and e showed mutations in four and one sites, predominantly in the RdRp region.Conclusion:The outbreak caused by the NoV GⅡ.17 [P17] subtype in Chaoyang District from 2014 to 2024 continues, with a significant increase in 2024, and it becomes the dominant gene subtype from October to December. The sequence formation of the NoV GⅡ.17 [P17] subtype in Chaoyang District from January to April 2022 and from May to December 2024 shows two different evolutions, with specific mutation sites, requiring continuous monitoring of the NoV GⅡ.17 [P17] subtype.

Objective:To analyze the incidence of surgical site infection (SSI) in patients undergoing colorectal cancer (CRC) surgery and to identify risk factors associated with SSI in an attempt to provide a reference for clinical prevention strategies.Methods:A retrospective cohort study was conducted. Clinical data were retrospectively collected from a total of 2,248 patients who underwent surgery for pathologically confirmed CRC between 2017 and 2022 at two centers: Huangshan Shoukang Hospital ( n=649) and Northern Jiangsu People's Hospital ( n=1 599). Inclusion criteria consisted of the following: (1) age >18 years; (2) pathologically confirmed CRC treated with curative resection, including extended resections (e.g. pelvic exenteration); (3) no surgical incisions other than abdominal or perineal; and (4) no use of prosthetic implants. The incidence of SSI was analyzed, and multivariate logistic regression was used to identify independent its risk factors. Results:A total of 121 patients (5.4%) developed SSI. Among them, 68 cases (56.2%) were organ/space infections, 35 cases (28.9%) were deep incisional infections, and 18 cases (14.9%) were superficial incisional infections. The median postoperative hospital stay was significantly longer in patients with SSI compared to those without (21.0 days vs. 13.0 days, U=65,754, P<0.001). The median hospitalization cost was also significantly higher in the SSI group (56,550 yuan vs. 43,645 yuan, U=72,008, P<0.001). Multivariate logistic regression analysis identified body mass index (BMI) ≤ 20 kg/m 2 (OR=4.25, 95%CI: 3.38-5.34, P<0.001), diabetes mellitus (OR=3.44, 95%CI: 1.89-6.24, P<0.001), open surgery (OR=4.23, 95%CI: 2.37-7.56, P<0.001), and colostomy or ileostomy (OR=1.67, 95% CI: 1.04-2.69, P=0.034) as independent risk factors for SSI. Conclusion:To prevent SSI following CRC surgery, attention should be given to optimizing body weight and glycemic control, promoting minimally invasive surgical approaches when feasible, and cautiously considering the necessity of colostomy or ileostomy.

Objective: This study aims to explore the association between oral lichen planus (OLP) and Hashimoto’s thyroiditis (HT) and its anti-thyroid antibodies to provide clinical evidence for thyroid disease screening in patients with OLP. Methods: This study was approved by the institutional ethics committee. A total of 125 clinically and histopathologically confirmed patients with OLP were enrolled as the case group, and they were matched with 125 non-OLP controls based on sex and age. Demographic data (gender, age, lesion type, and disease duration) were collected from both groups. Serum levels of thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) were measured to analyze their associations with sex, age, lesion type, and disease duration in patients with OLP. Result: The prevalence of HT in patients with OLP was 31.20%, significantly higher than that in the control group (9.60%) (χ2=18.504, P<0.001). The prevalence of HT in female patients with OLP (39.13%) was significantly higher than that in male patients (9.09%)（χ2=10.93，P<0.001）. The positivity rate of thyroid peroxidase antibodies (TPOAb) in patients with OLP (17.6%) was significantly higher than in the control group (4.0%) (χ2=10.989, P<0.001). The TPOAb positivity rate was significantly higher in female patients (22.83%) than in male patients (3.03%) (χ2=5.210, P=0.014). There was no statistically significant difference in the positivity rate of TgAb between patients with OLP (7.2%) and the control group (3.2%) (P>0.05). Patients with erosive lesions had a significantly higher TPOAb positivity rate (25.0%, 17/68) compared to those with non-erosive lesions (8.77%, 5/57), and the difference was statistically significant (χ2=4.831, P=0.028). Logistic regression analysis revealed that female patients with OLP had an 8.935-fold higher risk of being TPOAb positive compared to males (OR=8.935, 95%CI: 1.134-70.388, P=0.038). Patients with erosive OLP lesions had a 3.199-fold higher risk of TPOAb positivity compared to those with non-erosive lesions (OR=3.199, 95%CI: 1.064-9.618, P=0.038). Conclusion The prevalence of HT is higher in patients with OLP, with higher positivity rates of anti-thyroid antibodies observed in female patients and those with erosive OLP lesions. This suggests that thyroid disease screening should be incorporated into the clinical management of patients with OLP, especially for women and patients who present with erosive lesions.

[Objective] To establish a new scoring system to predict the perioperative outcomes (operation time, intraoperative blood loss, and trifecta achievement) in patients undergoing robot-assisted partial nephrectomy (RAPN) by integrating the RENAL and Mayo adhesive probability (MAP) scores. [Methods] Clinical data of 178 patients with renal cell carcinoma who underwent RAPN performed by the same surgeon in our hospital during Jan.2015 and Jan.2022 were retrospectively analyzed.The RENAL and MAP scores of all patients were calculated.Linear regression and logistic regression were used to evaluate the associations between the components of the RENAL and MAP scores (a total of 6 variables) and perioperative outcomes.The factors with significant associations were then included into logistic regression analysis to identify independent predictors for constructing an assessment system for perioperative outcomes, and the receiver operating characteristic (ROC) curve was plotted to calculate the area under the curve (AUC) to predict its efficacy. [Results] Multivariate linear regression analysis showed that tumor size (β=6.14, 95%CI: 1.93—10.34, P=0.004), exophytic rate (β=10.60, 95%CI: 3.44—17.76, P=0.004), and perinephric fat thickness (β=16.48, 95%CI: 8.52—24.45, P<0.001) were significantly associated with operation time.Tumor size (β=10.55 95%CI: 5.60—15.49, P<0.001) was associated with both intraoperative blood loss and trifecta achievement (OR=1.73, 95%CI: 1.26—2.36, P=0.001). Multivariate logistic regression analysis of these 3 factors identified tumor size (OR=9.07, 95% CI: 1.18—69.45, P=0.03) and perinephric fat thickness (OR=2.28, 95%CI: 1.86—6.04, P=0.01) as independent predictors of perioperative outcomes.Based on these findings, the tumor size and perinephric fat thickness (RP) scoring was constructed, which demonstrated better predictive ability than RENAL score or MAP score alone (RP vs.RENAL vs.MAP: 0.766 vs.0.548 vs.0.684). [Conclusion] The RP score includes fewer variables than the RENAL and MAP scores but outperforms them.

OBJECTIVES: This systematic review examines recent pharmacoeconomic literature on denosumab' cost-effectiveness for bone metastasis treatment, providing evidence-based insights to guide healthcare policy decisions. METHODS: A comprehensive literature search was performed across Cochrane, PubMed, EMBASE (Ovid), CNKI, and Wanfang databases to identify original articles published between 2017 and 2023. Key words consisted of bone metastases, denosumab, and cost-effectiveness in the search strategy. The methodological quality of the included studies was assessed utilizing the revised Consolidated Health Economic Evaluation Reporting Standards (CHEERS 2022). Data was extracted regarding methodological characteristics and cost-effectiveness analyses. RESULTS: A total of 111 studies were retrieved, of which 6 met the inclusion criteria. All included studies were based on clinical trials and published literature data and exhibited high methodological quality. Up to 83% (5 out of 6) of comparisons demonstrated that denosumab was more cost-effective or dominant compared to zoledronic acid. The adjusted incremental cost-effectiveness ratios varied substantially by tumor type, ranging from CZK 436,339.09 to USD 136,234 per skeletal-related event avoided and from CZK 61,580.95 to USD 118,392.11 per quality-adjusted life year gained. CONCLUSIONS The majority of the included studies support denosumab as a more cost-effective treatment option for bone metastases in solid tumors compared to zoledronic acid. The application of CHEER (2022) enhances the reliability of pharmacoeconomic evaluations.

INTRODUCTION: Adverse childhood experiences (ACEs) are associated with significant long-term impacts, yet few interventions specifically target ACE exposure, especially in Asian populations. Anchor, Singapore's first home visitation programme, addresses maltreat-ment among preschool children. This study evaluated Anchor's impact on children's developmental and behavioural outcomes. METHOD: We conducted a prospective evaluation of children under 4 years assessed for maltreatment from November 2019 to July 2023. Developmental and behavioural progress was measured every 6 months using the Ages and Stages Questionnaires (ASQ-3) and ASQ:Social-Emotional (ASQ:SE-2), and annually using the Child Behaviour Checklist (CBCL). RESULTS: The results of 125 children (mean age 20.0 months, 48% female) were analysed. The mean length of stay in programme was 21.2 (7.3) months. At baseline, 92 (73.6%) children were at risk of develop-mental delay and 25 (31.7%) children aged ≥18 months had behavioural concerns. The programme was associated with significant improvements in gross motor (P=0.002) and fine motor (P=0.001) domains of the ASQ-3 and internalising problem scale (P=0.001) of the CBCL. CONCLUSION Anchor effectively enhances develop-mental and behavioural outcomes for children exposed to maltreatment. Targeted early intervention through such programmes can mitigate adverse impacts, optimising developmental trajectories and potentially reducing the long-term clinical and economic burdens associated with ACEs.
