Although the tumor suppressor P53 is known to regulate a broad network of signaling pathways,it is still unclear how certain drugs influence these P53 signaling netw ***,we used a comprehensive singlecell multiomics view of the effects of ginsenosides on cancer *** and proteome profiling revealed that the antitumor activity of ginsenosides is closely as sociated with P53 protein.A miRNA-proteome interaction network revealed that P53 controlled the transcription of at least 38 proteins,and proteomemetabolome profiling analysis revealed that P53 regulated proteins involved in nucleotide metabolism,amino acid metabolism and"Warburg effect".The results of integrative multiomics analysis revealed P53 protein as a potential key target that influences the anti-tumor activity of ***,by applying affinity mass spectrometry(MS)screening and surface plasmon resonance fragment library screening,we confirmed that 20(S)-protopanaxatriol directly targeted adj acent regions of the P53 DNA-binding pocket and promoted the stability of P53-DNA interactions,which further induced a series of omics changes.

Based on the needs of the market,a new 52 MPa medium-density and high-strength ceramic proppant was prepared by adopting third grade bauxite and clay as raw materials and using the solid phase sintering method,and the effect of the firing temperature on the microstructure,phase composition and mechanical properties of the ceramic proppant was studied. The broken resistance mechanism of this ceramic proppant was also discussed. The results show that the main phases of the prepared ceramic proppant are mullite and corundum; the broken rates are 3. 92% and 7. 21% under 52 MPa and69 MPa,respectively.

乳腺癌是女性常见的肿瘤,如今乳腺癌实体肿瘤通过相应的治疗可取得较好的疗效,但人表皮生长因子受体2(HER2)阳性乳腺癌侵袭性较强、恶性程度高,需引起患者及医务人员的重视。本文回顾性分析1例激素受体阴性、HER2阳性伴胃肠功能紊乱的乳腺癌患者诊治经过。患者初诊为局部晚期炎症乳腺癌伴腋窝淋巴结转移,给予新辅助化疗及手术治疗。术后3年后病情进展,予以伊尼妥单抗联合白蛋白紫杉醇,后续伊尼妥单抗单独靶向治疗,病情持续缓解。提示对于HER2阳性晚期乳腺癌,伊尼妥单抗是个很好的单抗类药物选择。

基于低硫重质船用燃料油生产需要以及炼厂最大化生产重整原料和乙烯裂解原料转型升级背景,本文针对典型炼化一体化企业生产低硫船用燃料油,分别采用沸腾床和浆态床的不同重油加工方案从产品分布、产品性质及后续加工路线等进行经济性分析。结果表明,相比于浆态床加氢方案,尽管沸腾床渣油加氢转化率低于浆态床,但由于转化后的产品中干气收率低、各种馏分油的氮含量显著低于浆态床方案,且可以直接生产低硫船用燃料油、不存在废渣处理等优势,此外,耗氢较低,同时航煤、石脑油及芳烃产量增量明显,以50美元效益测算价测算,沸腾床方案扣消费税毛利较浆态床方案高16.13亿元。可见,对于有低硫船用燃料油生产需求的炼化企业,采用沸腾床重油加工路线在经济性方面更具竞争力。

AIM: To study the effect of arsenic trioxide (As2O3) on human hepatoma cell line BEL-7402 in ***: Human hepatoma cell line BEL-7402 cultured in vitro was inoculated into nude mice and arsenic trioxide,5-Fu and saline were injected into abdominal cavity of the nude mice respectively. The volumes of tumor and general conditions of the nude mice and structural changes of the liver and kidney were observed. Morphologic changes were studied under electron microscope. Expression of AFP was investigated by immunohistochemical ***: As2O3 could inhibit the growth of tumor. The tumor growth inhibitory rate in mice treated with 2.5 mg/kg As2O3 was 53.42% on the tenth day. The tumor growth inhibitory rate in mice treated with 5 mg/kg As2O3 was 79.28% on the fifth day and 96.58% on the tenth day respectively. As2O3 did not damage the liver and kidney of nude mice, or affect the blood system. Typical apoptotic morphological changes were found under electron microscope, and the change of mitochondria was obvious. The expression rate of AFP declined after ***: Arsenic trioxide can induce apoptosis of human hepatoma cells, and inhibit proliferation of tumor with no obvious side effects on liver and kidney.
