随着开采深度的增加,软岩巷道占比逐年加大,合理的软岩巷道支护方案为矿井安全高效开采提供了重要保障。为了研究掘进巷道不同数量锚杆、锚索耦合支护的效果,以鄂尔多斯红庆梁矿12301胶运巷掘进巷道为研究对象,利用FLAC^(3D)软件研究在不同数量锚杆、锚索联合支护条件下,12301胶运巷掘进巷道围岩塑性区和围岩应力规律。结果表明:在方案1的支护条件下,减少2根帮锚杆,围岩剪切破坏区明显增大,而在减少两根顶锚杆的情况下,围岩剪切破坏区变化不大。方案2在方案1减少两根顶锚杆的前提下,巷道顶板最大垂直应力增加了20%,巷道两帮最大垂直应力增加了0.3%.方案3在方案1减少2根帮锚杆的前提下,巷道顶板最大垂直应力增加了40%,巷道两帮最大垂直应力增加了0.93%.

OBJECTIVE: To observe the anticancer effects of the granular preparation of Tenglong Buzhong decoction(藤龙补中汤,TBD), i.e Tenglong Buzhong granules(藤龙补中颗粒, TBG), in human SW620 colon cancer. METHODS: BALB/c nude mice were subcutaneously transplanted with SW620 cells, and treated with TBG(2.56 g/kg, once per day) and/or 5-Fu(104 mg/kg, once per week) for 21 d. Apoptosis, Caspase activities and cellular senescence were measured by commercial kits. The protein expression and phosphorylation were detected by Western blot or immunohistochemistry. RESULTS: TBG and 5-Fu inhibited tumor growth. The tumor inhibition rate of the TBG, 5-Fu, and TBG+5-Fu groups was 42.25%, 51.58%, and 76.08%, respectively. Combination of TBG and 5-Fu showed synergetic anticancer effects. TBG and 5-Fu induced apoptosis, activated caspase-3,-8, and-9, increased SMAC expression, inhibited XIAP expression. TBG induced cellular senescence, upregulated cyclin-dependent kinase inhibitor 1a(CDKN1a) and cyclin-dependent kinase inhibitor 2a(CDKN2a) expression, and inhibited phosphorylation of retinoblastoma-associated protein(RB) and expression of cyclin E1(CCNE1) and cyclindependent kinases(CDK) 2. TBG also inhibited angiogenesis accompanied by downregulation of vascular endothelial growth factor(VEGF) and hypoxiainducible factor-1α(HIF-1α). CONCLUSIONS: TBG inhibits SW620 colon cancer growth, induces apoptosis via SMAC-XIAP-Caspases signaling, induces cellular senescence through CDKN1a/CDKN2a-RB-E2F signaling, inhibits angiogenesis by down-regulation of HIF-1α and VEGF, and enhances the effects of 5-Fu.

Lipiodol chemotherapeutic emulsions remain one of the main choices for the treatment of unresectable hepatocellular carcinoma(HCC) via transarterial chemoembolization(TACE). However, the limited stability of Lipiodol chemotherapeutic emulsions would lead to rapid drug diffusion, which would reduce the therapeutic benefit and cause systemic toxicity of administrated chemotherapeutics. Therefore, the development of enhanced Lipiodol-based formulations is of great significance to enable effective and safe TACE treatment. Herein, a stable water-in-oil Lipiodol Pickering emulsion(LPE) stabilized by pH-dissociable calcium carbonate nanoparticles and hemin is prepared and utilized for efficient encapsulation of lipoxygenase(LOX). The obtained LOX-loaded CaCO3&hemin-stabilized LPE(LHCa-LPE) showing greatly improved emulsion stability could work as a pH-responsive and self-fueling microreactor to convert polyunsaturated fatty acids(PUFAs), a main component of Lipiodol, to cytotoxic lipid radicals through the cascading catalytic reaction driven by LOX and hemin, thus inducing ferroptosis of cancer cells. As a result, such LHCa-LPE upon transcatheter embolization can effectively suppress the progression of orthotopic N1S1 HCC in rats. This study highlights a concise strategy to prepare pH-responsive and stable LPE-based self-fueling microreactors, which could serve as bifunctional embolic and ferroptosis-inducing agents to enable proof-of-concept transarterial ferro-embolization therapy of HCC.
