Background: Conditional survival(CS) has been established as a clinically relevant prognostic factor for cancer survivors, and the CS in gallbladder(GB) cancer has not yet been fully evaluated. In this study, we evaluated the cancerspecific CS rate and cancer-specific survival(CSS) rate in patients with GB cancer at multiple time points and investigated prognostic factors which affect cancer-specific CS rate to provide more accurate survival ***: Between 2004 and 2013, a total of 9760 patients with GB cancer were identified from the Surveillance,Epidemiology, and End Results(SEER) data. The 3-year cancer-specific CS rate was calculated using the covariateadjusted survival function in the Cox model for each year since diagnosis, and the results were analyzed together with the adjusted CSS rates at the same time points. Cox proportional hazards regression was performed to ascertain the individual contribution of factors associated with CSS rate at diagnosis and cancer-specific CS rates at 1,3, and 5 years after ***: The adjusted 5-year CSS rate was 26.1 %. The adjusted 3-year cancer-specific CS rates at 1,2,3,4, and 5 years after diagnosis were 55.5,72.2,81.5,86.8, and 90.5%, respectively. At the time of diagnosis, age, race, histology, grade,T, N, and M categories, surgery, radiotherapy, insurance status, and marriage status were significant prognostic factors of CSS. Five years after diagnosis, however,T and M categories were significant prognostic factors for survivors(P = 0.007 and P = 0.009, respectively), whereas surgery and radiotherapy were ***: T and M categories were significant prognostic factors even 5 years after the initial diagnosis, whereas local treatments at the time of diagnosis were not, suggesting that patients with GB cancer at high risks might need further adjuvant therapy after primary treatments. The combined analysis of CSS and cancer-specific CS rates offered more accurate survival information for pa

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

Science China Chemistry 2025年

Axially chiral phosphines are a class of extremely important ligands in asymmetric catalysis. Herein, an unprecedented copper（I）-catalyzed asymmetric SNAr reaction with HP（S）R2is uncovered, which delivers a series of axially chiral phosphine derivatives in high yields with excellent enantioselectivity. Furthermore, the diastereoselective reaction with the kinetic resolution of racemic HP（S）ArR proceeds smoothly, providing the products with moderate diastereoselectivity and excellent enantioselectivity. Control experiments indicate that HP（S）Ph2is much more active than HPPh2and HP（O）Ph2as the pronucleophile in the present reaction. It is found that the SNAr reaction （the first SNAr） proceeds in a desymmetric manner, providing the desired chiral products while a continued SNAr reaction （the second SNAr） slightly occurs in a kinetic resolution manner in the present catalytic system, which enhances the ee of the desired chiral products. DFTcalculations support a concerted reaction pathway rather than a step-wise mechanism. Finally, axially chiral olefin-phosphines produced by the present method work as suitable ligands in Pdcatalyzed asymmetric allylic substitution with C-, N-, and O-nucleophiles and Rh-catalyzed asymmetric addition of arylboronic acid to benzil.

牛病毒性腹泻病毒(Bovine viral diarrhea virus, BVDV)是引起犊牛(Bos sp.)病毒性腹泻的主要病原之一，导致犊牛免疫力降低，患病率和死亡率升高。目前对BVDV常用的检测方法存在灵敏度较低、容易出现假阳性等状况。本研究基于微滴式数字PCR(droplet digital PCR, ddPCR)技术，建立BVDV精准检测技术。首先针对BVDV 5'UTR基因保守序列区域设计引物和探针，合成BVDV 5'UTR基因并构建质粒标准品。使用BVDV质粒标准品分别建立实时荧光定量PCR(real-time quantitative PCR, qPCR)和ddPCR检测方法，并优化其反应参数和条件，分析其灵敏度、特异性和重复性，并进行了临床应用。结果显示，本研究建立的qPCR方法中，最佳引物和探针浓度分别为300和500 nmol/L，标准曲线呈良好的线性关系，最低检测下限为1×10～4 copies/μL，具有良好的特异性和重复性。建立的ddPCR方法中，最低检测下限为0.64 copies/μL，比qPCR灵敏性高15 625倍，该方法具有良好的特异性和重复性。临床检测了82份样品，ddPCR检出率为15.58%,qPCR检出率为14.63%。本研究建立的ddPCR方法比qPCR方法更加灵敏、高效、特异且重复性良好，为BVDV鉴别诊断提供了技术支持。

Acta Mathematica Sinica,English Series 2005年第5期21卷 1099-1106页

作者： yi jun HU School of Mathematics and Statistics Wuhan University Wuhan 430072 P. R. China

In this paper, we extend the classical compound binomial risk model to the case where the premium income process is based on a Poisson process, and is no longer a linear function. For this more realistic risk model, Lundberg type limiting results for the finite time ruin probabilities are derived. Asymptotic behavior of the tail probabilities of the claim surplus process is also investigated.

Topology evolutions of silhouettes

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第10期8卷 1671-1680页

We give the topology changing of the silhouette in 3D space while others study the projections in an image. Silhou- ettes play a crucial role in visualization, graphics and vision. This work focuses on the global behaviors of silhouettes, especially their topological evolutions, such as splitting, merging, appearing and disappearing. The dynamics of silhouettes are governed by the topology, the curvature of the surface, and the view point. In this paper, we work on a more theoretical level to give enu- merative properties of the silhouette including: the integration of signed geodesic curvature along a silhouette is equal to the view cone angle; in elliptic regions, no silhouette can be contained in another one; in hyperbolic regions, if a silhouette is homotopic to a point, then it has at least 4 cusps; finally, critical events can only happen when the view point is on the aspect surfaces (ruled surface of the asymptotic lines of parabolic points with surface itself). We also introduce a method to visualize the evolution of silhouettes, especially all the critical events where the topologies of the silhouettes change. The results have broad applications in computer vision for recognition, graphics for rendering and visualization.

PROMOTING SILTATION EFFECTS AND IMPACTS OF HENGSHA EAST SHOAL ON THE YANGTZE RIVER ESTUARY

引用

Journal of Hydrodynamics 2011年第5期23卷 649-659页

作者： XIE jun YAN yi-xin College of Harbor Coastal and Offshore Engineering Hohai University Nanjing 210098 China Shanghai Waterway Engineering Design and Consulting Co. Ltd Shanghai 200120 China

For the Hengsha East Shoal Promoting Siltation Project in the Yangtze River Estuary, this work developed a formula for calculating sediment carrying capacity based on variable coefficients and a mathematical model for suspended sedimentation using variable saturation recovery coefficients. Not only does the model yield good verification, preferably give the hydrodynamics and the sediment concentration, but also reach a good agreement between the simulation results andlux by tide for studying the effect the measured topographical changes in the promoting siltation zone of the Hengsha East Shoal. Moreover, this article proposes a method for examing the net sediment tran- sportation fs of the project of promoting siltation and comparatively analyzes the current siltation of the Hengsha East Shoal and siltation mouth layouts, entrance widths, entrance bottom elevations, and the impact of the South Main Dike on promoting siltation through calculating the net sediment transportation flux by tide over the fixed bed and the direct movable bed numerical simulations. The results are in good agreement with each other, indicating that the method for calculating the net sedi- ment transportation flux by the tide is also useful for assessing the project in promoting siltation. Finally, we use the modeling results to analyze the water and sediment diversion ratios and the changes in silting and scouting in riverbeds and draw the conclusion that the completion of the Hengsha East Shoal Promoting Siltation Project would not adversely affect the Yangtze River Estuary Deepwater Channel Project.
