AIM To investigate the mechanisms by which Sheng-jiang powder(SJP) ameliorates obesity-induced pancreatic inflammatory *** Sprague-Dawley rats were randomized into three groups: normal group(NG), obese group(HLG), or SJP treatment group(HSG). Obesity was induced by feeding a high-fat diet in the HLG and HSG, while the NG received standard chow. Rats were euthanized after 12 wk, and blood and pancreatic tissues were collected for histopathological analyses. Nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB) and transforming growth factor beta(TGF-β) expression, serum triglyceride and adiponectin levels, and apoptosis in pancreatic acinar cells were assessed. A high-fat AR42 J acinar cell injury model was established using very low-density lipoprotein(VLDL). AR42 J acinar cell culture supernatant, treated with different interventions, was applied to seven groups of pancreatic stellate cells(PSCs). The proliferation of PSCs and the expression of fibronectin and type I collagenase were *** Compared with the NG, we found higher pathological scores for pancreatic tissues, lower serum adiponectin levels, higher expression levels of NF-κB in pancreatic tissues and TGF-β in pancreatic inflammatory cells, and increased apoptosis among pancreatic acinar cells for the HLG(P ting key molecules of the

Micro-extrusion compression molding and surface modification were proposed for the mass fabrication of a superhydrophobic thermoplastic polyurethane sensor (TCGS).Inspired by scorpions, TCGS features Archimedean spiral crack arrays and micropores, achieving 218.13 sensitivity at 2% strain, a 4300% increase, and over 5000 usage cycles of *** robust superhydrophobicity of TCGS improves sensitivity and stability for detecting small-scale liquid leakage, allowing precise monitoring across various sizes and compositions while providing early warnings in various scenarios. Liquid leakage of pipeline networks not only results in considerable resource wastage but also leads to environmental pollution and ecological imbalance. In response to this global issue, a bioinspired superhydrophobic thermoplastic polyurethane/carbon nanotubes/graphene nanosheets flexible strain sensor (TCGS) has been developed using a combination of micro-extrusion compression molding and surface modification for real-time wireless detection of liquid leakage. The TCGS utilizes the synergistic effects of Archimedean spiral crack arrays and micropores, which are inspired by the remarkable sensory capabilities of scorpions. This design achieves a sensitivity of 218.13 at a strain of 2%, which is an increase of 4300%. Additionally, it demonstrates exceptional durability by withstanding over 5000 usage cycles. The robust superhydrophobicity of the TCGS significantly enhances sensitivity and stability in detecting small-scale liquid leakage, enabling precise monitoring of liquid leakage across a wide range of sizes, velocities, and compositions while issuing prompt alerts. This provides critical early warnings for both industrial pipelines and potential liquid leakage scenarios in everyday life. The development and utilization of bioinspired ultrasensitive flexible strain sensors offer an innovative and effective solution for the early wireless detection of liquid leakage.

目的用人心脏瓣膜间质细胞(hVICs)在体外培养并用钙化诱导液建立瓣膜钙化模型,观察hVICs钙化过程中Notch1蛋白表达及细胞凋亡情况,探讨Notch1蛋白在hVICs凋亡与钙化关系中的作用。方法将体外培养的hVICs随机分为两组,钙化组用含钙化诱导液的培养基培养,以建立钙化模型,并按1~7天分别诱导细胞,观察钙化的动态过程;空白组用正常培养基(I-GRO PLUS)培养。所有hVICs均培养7天。检测两组细胞钙化结节数目、BMP-4蛋白、Notch1蛋白的表达及hVICs凋亡率。然后将钙化组中诱导钙化细胞再随机分脂多糖组(LPS)、Notch1抑制剂组(γ分泌酶抑制剂,DAPT)、对照组(只加钙化诱导液)体外培养3天,检测BMP-4、Notch1、半胱氨酸天冬氨酸蛋白酶3(Caspase3)的表达。结果与空白组细胞比较,钙化组细胞钙化及Notch1蛋白的表达均高于空白组,且随着诱导天数的增加而增加;细胞凋亡率在钙化诱导3天时最高,随后逐渐下降。LPS组与对照组比较,细胞凋亡和钙化均随着Notch1蛋白的表达增加而增加;DAPT组与对照组比较,细胞凋亡和钙化均减少。结论hVICs钙化与细胞凋亡有着密切的关系,且Notch1蛋白在hVICs凋亡与钙化关系中起着重要的作用。

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.
