We derive a blow-up formula for holomorphic Koszul–Bry.inski homologies of compact holomorphic Poisson manifolds. As applications, we investigate the invariance of the E1-degeneracy.of the Dolbeault–Koszul–Bry.inski spectral sequence under Poisson blow-ups, and compute the holomorphic Koszul–Bry.inski homology.for del Pezzo surfaces and two complex nilmanifolds with holomorphic Poisson structures.

surveillance recommendations for gastric cancer（GC） in current guidelines focused on advanced precancerous lesions and were based on precise diagnosis of severity.extent of baseline lesions. We aimed to develop a less endoscopy.related equipment-dependent risk-stratification tool, and assessed whether mild-precursor-lesion patients can be safely.exempt from surveillance. In the multicenter community.ased cohort, 75,051 participants receiving baseline endoscopy.were enrolled during 2015–2017 and followed-up until 2021. Cumulative incidence rates（CIRs） of GC for precancerous-conditions were calculated by.Kaplan-Meier method and compared by.Log-rank tests. Mixedeffects Cox regression models were used to detect potential factors for progression towards GC. A risk score was calculated as counts of selected factors. An independent cohort, including 26,586 participants was used for external validation. During a median follow-up of 6.25 y.ars, CIRs of GC were 0.302%, 0.436%, and 4.756% for normal group, non-neoplastic（atrophic gastritis/intestinal metaplasia） and neoplastic lesions（low-grade/high-grade dy.plasia）, respectively.Ptrends, including male, ≥60 y.ars, smoking, and limited vegetable consumption, were selected for risk-stratification. High-risk patients（≥3 risk factors） with non-neoplastic lesions showed higher GC risks（adjusted HR=7.73, 95%CI: 4.29–13.92）, and their four-y.ar CIR reached the one-y.ar CIR of neoplastic lesions. Further categorizing non-neoplastic lesions by.histological grade, both patients with moderate-to-severe lesions（aHR=3.07, 95%CI: 1.67–5.64） and high-risk patients with mild lesions（aHR=7.29, 95%CI: 3.58–14.86） showed higher risks. Consistent trends were observed in validation cohort. High-risk mild-precursor-lesion patients should receive surveillance within 3–5 y.ars after baseline screening. Our study.provides evidence on supplementing current guideline recommendations.
