Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

A microfluidic extracorporeal membrane oxygenator is an advanced extracorporeal life support device designed using microfluidic technology,capable of providing oxygenation support to patients with severe respiratory failure and other pulmonary diseases via extracorporeal circulation.Compared to conventional extracorporeal membrane oxygenators,it features a more superior biomimetic design,demonstrating potentials for improved therapeutic outcomes and reduced complications.This review summarizes the research progress of microfluidic extracorporeal membrane oxygenators in terms of hemodynamics,membrane materials,biocompatibility,gas exchange efficiency,and structural design.It analyzes how factors such as blood channel design,material selection and surface modification techniques impact the performance of microfluidic extracorporeal membrane oxygenators,such as biomimetic flow paths minimizing shear stress and endothelial cell linings significantly reducing thrombosis.Finally,the limitations of microfluidic extracorporeal membrane oxygenators are discussed,along with prospects for future development.Innovations are still needed in enhancing biocompatibility,portability,manufacturability,and cost reduction for microfluidic extracorporeal membrane oxygenators.

Objective To investigate the protective effects and potential mechanisms of tetrahydrocurcumin(THC)on thoracic aortic aneurysm and dissection(TAAD)in mice.Methods TAAD was induced in 3-week-old C57BL/6J mice by oral administration of β-aminopropionitrile(BAPN)(diluted in drinking water,1 g/(kg·d)).Eighty mice were divided randomly into Con,BAPN,BAPN+THC,and BAPN+THC+3-TYP(SIRT3 inhibitor)groups(n=20 mice per group).The survival rate of mice in each group was recorded after 4 weeks.The maximum diameter of the aorta was measured and the histomorphology and aortic wall elastin integrity were evaluated by hematoxylin and eosin and elastin van Gieson staining.Macrophage infiltration was detected by immunohistochemical staining and α-smooth muscle actin(α-SMA)and osteopontin(OPN)expression were detected by immunofluorescence staining.The production of reactive oxygen species(ROS)was measured by dihydroethidium staining and superoxide dismutase(SOD)activity and malondialdehyde(MDA)levels were determined using kits.Protein expression levels of matrix metalloproteinase(MMP)2,MMP9,interleukin(IL)-6,tumor necrosis factor(TNF)-α,nuclear factor erythroid 2-related factor 2(NRF2),NADPH oxidase 2(NOX2),α-SMA,OPN,sirtuin 3(SIRT3),Ac-SOD2,and SOD2 were measured by Western Blot.Results Mice in the BAPN+THC group showed significantly higher survival and a lower incidence of TAAD compared with the BAPN group and the degree of aortic dilatation and morphology and structure were improved(P＜0.05).Infiltration of CD68-positive macrophages and MMP2,MMP9,IL-6,and TNF-α expression levels were lower(P＜0.05),ROS generation,MDA content,and NOX2 expression in aortic tissue were also significantly decreased,while SOD activity and NRF2 expression were increased(P＜0.05).α-SMA expression was also increased,while OPN expression was reduced(P＜0.05).SIRT3 expression was increased while the Ac-SOD2/SOD2 ratio was decreased(P＜0.01).Treatment with the SIRT3-specific inhibitor and silencing of SIRT3 counteracted the ability of THC to resist TAAD via the SIRT3 signaling pathway(all P＜0.05).Conclusions THC alleviated inflammation and oxidative stress in aortic tissues by activating the SIRT3 signaling pathway,thus inhibiting the phenotypic transformation of vascular smooth muscle cells and resisting the formation of TAAD in mice.
