Hepatoma Research 2018年第3期4卷 1-8页

作者： Yoshiyuki Wada Yuko Takami Hajime Matsushima Masaki Tateishi Tomoki Ryu Munehiro Yoshitomi hideki saitsu Department of Hepato-Biliary-Pancreatic Surgery Clinical Research InstituteNational Hospital Organization Kyushu Medical CenterFukuoka 810-8563Japan

Aim: Sorafenib has been shown to improve time to tumor progression (TTP) and overall survival (OS) in patients with hepatocellular carcinoma (HCC);however, post-progression survival (PPS) has not been well characterized in these patients. This study aimed to evaluate the predictors of PPS by using time-dependent and dynamic changes in radiologic progression patterns, liver function, and performance status (PS) in patients with advanced HCC receiving sorafenib treatment. Methods: We retrospectively analyzed the clinical characteristics of 128 advanced HCC patients with Child-Pugh scores ≤ 7 at the initiation of sorafenib treatment. Results: The median TTP, OS, and PPS were 3.8, 15.6, and 9.9 months, respectively. At the time of confirmation of radiologic progressive disease (PD), a total of 46 (35.6%) patients showed impairments in their PS of ≥ +1 points over time. For the Child-Pugh score, 27 (21.1%) and 26 (10.9%) patients exhibited an impairment of ≥ +1 and ≥ +2 points, respectively. Multivariate analysis identified the following independent predictors of PPS: impairment in the PS score of ≥+1 point [hazard ratio (HR) 1.81, 95% confidence interval (CI) 1.16-2.82], impairment in the Child-Pugh score of ≥ +2 points (HR 3.70, 95% CI 1.68-8.15), radiologic pattern of progression (target lesion growth and emergence of a new lesion) (HR 2.91, 95% CI 1.79-2.91), a TTP < 4 months(HR 1.87, 95% CI 1.21-2.91), second-line treatment after radiologic confirmation of PD (HR 0.16, 95% CI 0.08-0.32), and continuous sorafenib treatment after radiologic confirmation of PD (HR 1.76, 95% CI 1.06-3.00). Conclusion: PPS in patients with advanced HCC can be characterized by using time-dependent dynamic changes in clinical parameters.

A Comparative Study of Two Tree-Based Models for Predicting Flyrock Velocity at Open Pit Bench Mining

引用

Open Journal of Applied Sciences 2024年第2期14卷 267-287页

Blasting is a cost-effective technique to break hard rock volumes by using explosives in the mining and civil engineering realms. Moreover, although blasting is a designed process and plays an indispensable role in these industries, it can also have multiple adverse environmental impacts. One such effect is flyrock, which poses risks to nearby machinery, and residential structures, and can even lead to injuries or fatalities. To optimize blasting efficiency as well as restrict side effects, prediction of the blast aftereffects is vital. Therefore, the present work focuses on using two machine learning methods to predict the velocity of flyrock in the open pit mine. To address this issue, a comprehensive dataset was gathered from the open pit mine. Then, Decision Tree and Random Forest algorithms were employed to predict flyrock velocity. The Random Forest model demonstrated superior performance compared to the Decision Tree model. Nonetheless, the performance of the Decision Tree model was deemed satisfactory, as evidenced by its coefficient of determination value of 0.83, mean squared error (MSE) of 4.2, and mean absolute percentage error (MAPE) of 5.6%. Considering these metrics, it is reasonable to conclude that tree-based algorithms can be effective in predicting flyrock velocity.

晚期糖基化终末产物受体(receptor for advanced glycation end product,RAGE)是免疫球蛋白受体,能够与多种配体结合,研究发现RAGE参与了非专职吞噬细胞对组蛋白修饰的微米颗粒的吞噬过程,但目前没有研究证明组蛋白是RAGE的配体。该研究对组蛋白分子能否直接激活RAGE及其下游信号通路进行探究。使用共聚焦显微镜和流式细胞仪检测哺乳动物细胞对可溶性组蛋白分子的内化;采用钙黄绿素乙酰氧基甲酯/碘化丙啶染色法检测细胞活性;通过荧光探针2′,7′-二氯二氢荧光素二乙酸酯检测胞内活性氧水平;利用酶联免疫吸附剂测定法(enzyme-linked immunosorbent assay,ELISA)测定炎症因子的释放。结果表明,组蛋白分子能够被野生型HEK293T细胞内化并于胞内溶酶体中聚集,RAGE-敲除细胞则无法内化组蛋白;培养基组蛋白质量浓度在100μg/mL时对细胞无明显毒性,细胞活性正常;组蛋白能够通过RAGE刺激细胞活性氧水平升高,并释放炎症因子肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)和白细胞介素-6(interleukin-6,IL-6);组蛋白与DNA结合能够增强对RAGE的刺激。以上结果表明,组蛋白能够激活RAGE及其下游炎症通路。
