为明确微生物菌剂改善大蒜产地环境、提升产量品质的效果,利用常规施肥结合解淀粉芽孢杆菌W48发酵液进行大蒜田土壤处理,测定大蒜产量和品质相关指标,监测土壤理化性质及生物转化相关酶活性变化,定量分析菌剂处理后土壤和大蒜中邻苯二甲酸酯类塑化剂(PAEs)含量差异。结果表明,W48菌株具有分泌吲哚乙酸的能力,同时具备溶磷和产铁载体的潜力。施用W48微生物菌剂显著增加了植物根际土壤有机质、碱解氮、有效磷和速效钾含量,改善根际区域营养环境,提高了土壤碱性磷酸酶、蔗糖酶和脲酶等生物转化相关酶活性,提高了土壤氮、磷元素利用效率;与对照相比,微生物菌剂处理的小区大蒜增产10%,可溶性糖和维生素C含量等品质指标均有提高,其中可溶性糖显著增加了30%;邻苯二甲酸二正丁酯(DBP)和邻苯二甲酸二(2-乙基)己酯(DEHP)是土壤和大蒜中PAEs的主要检出类型,土壤中的平均浓度分别达到1874.05和337.12μg/kg,大蒜中几种PAEs残留量普遍较高,DBP最高为666.57μg/kg,其次为邻苯二甲酸二异丁酯(DIBP)409.93μg/kg和邻苯二甲酸丁苄酯(BBP)433.65μg/kg。菌剂对PAEs具有显著的体外降解能力,土壤处理后能够显著降低土壤中PAEs浓度,对DBP、DEHP和邻苯二甲酸二甲酯(DMP)的去除率分别为25.5%、76.1%和48.4%,但对大蒜中的PAEs含量影响不显著。以上结果为大蒜产地土壤污染物修复及改良提供了技术支撑。

2024年V2版《美国国家综合癌症网络结肠癌临床实践指南》的更新涵盖了诊断和治疗的多个领域,特别注重分子诊断技术的进步、免疫治疗的最新进展以及综合治疗方案的调整。在分子检测方面,指南推荐对疑似或已确诊的转移性腺癌病人进行更全面的基因分析,包括罕见基因突变/融合如POLE/POLD1、RET和NTRK的检测,并继续关注HER2、RAS、BRAF等基因突变。对于循环肿瘤DNA(ctDNA)的应用,指南持保守态度,建议仅在临床试验中使用,并在Ⅱ、Ⅲ期及接受辅助治疗的病人中谨慎使用ctDNA监测。治疗更新方面,推荐携带POLE/POLD1突变及错配修复功能缺陷(dMMR)/微卫星高度不稳定(MSI-H)的病人接受免疫治疗,尤其适用于存在不可切除转移的情况。同时,取消了抗表皮生长因子受体治疗对左半结肠肿瘤的限制,拓宽至所有适合的KRAS/NRAS/BRAF野生型病人,并将曲妥珠单抗的使用从RAS和BRAF野生型病人中解除限制,扩展到所有HER2扩增的结肠癌病人。此外,针对dMMR/MSI-H型病人的术后辅助化疗也进行了重组和更新建议,明确了辅助化疗在提升生存率方面的潜在限制。
