目的了解食管癌患者根治术后支持性照顾需求现状,分析其与自我效能及生活质量的关系,为改善患者预后提供参考。方法收集102例食管癌根治术后患者的一般资料,应用支持性照顾需求问卷(SCNS-SF34)、癌症自我管理效能感量表(SUPPH)、癌症病人生命质量测定量表(FACT-G)对其进行调查;采用Pearson相关分析探究支持性照顾需求与自我效能及生活质量间的相关性,采用多元线性回归分析支持性照顾需求的影响因素。结果食管癌根治术后患者的SCNS-SF34总得分为(95.85±21.67)分,SUPPH评分为(90.81±20.42)分,FACT-G评分为(59.16±13.75)分。Pearson相关分析显示,心理需求、健康信息需求、照顾及支持需求、生理及日常生活需求维度的评分与SUPPH及FACT-G各维度评分均呈负相关(P<0.05)。不同年龄、文化程度、家庭人均月收入、居住地的食管癌根治术后患者间,SCNS-SF34评分差异具有统计学意义(均P<0.05);多元线性回归结果显示,年龄、文化程度、家庭人均月收入、居住地、SUPPH评分、FACT-G评分为影响食管癌根治术后患者支持性照顾需求的主要因素(均P<0.05),可解释总变异的82.3%。结论食管癌根治术后患者普遍存在支持性照顾需求未被满足,支持性照顾需求与自我效能及生活质量呈负相关,且受不同因素影响,临床可进行针对性指导,以改善患者自我效能与生活质量。

以发酵番茄秸秆为试材,采用盆栽试验和高通量测序技术,研究了空白土壤(TCK)、添加发酵番茄秸秆(TT)、常规施肥处理(TS)、常规施肥混合添加发酵番茄秸秆(TTS)4个处理下种植番茄生长指标与土壤肥力指标以及土壤细菌和真菌群落微生物多样性的差异,以期为设施蔬菜秸秆的循环利用提供参考依据。结果表明:TT处理相较于TCK可以显著提升番茄植株茎粗、地上部分质量、单株产量,对叶绿素含量无显著影响;而TTS处理相较于TS处理,番茄植株茎粗、地上部分质量、单株产量及叶绿素含量并无显著差异。土壤理化指标方面添加配施发酵番茄秸秆,土壤有机质、碳氮比及速效磷、速效钾等有效养分含量显著升高;高通量测序发现,4个处理之间的细菌和真菌群落组成无显著性变化,TT处理相较于TCK处理,细菌Shannon多样性升高,真菌群落Shannon多样性变化不显著。不同处理间细菌群落和真菌群落的相对丰度发生显著性改变,表明配施发酵番茄秸秆可以提升番茄的产量及地上部质量,对提高植株叶绿素含量效果不显著。同时可以提升土壤的供肥能力,使土壤有机质、碳氮比及速效磷、速效钾等有效养分含量升高,使土壤细菌群落多样性升高,放线菌等部分优势菌群丰度增加,简单沤堆发酵的番茄秸秆可以作为优质的有机物料添加至栽培土壤中,实现设施蔬菜作物秸秆的循环利用。

The selection of salt-tolerant watermelon rootstocks requires the evaluation of its underlying mechanism. The present study investigated the effect of applying 200 mmol·L-1 NaCl on various physiological and biochemical parameters of Citrullus lanatus ‘Jingxin No.2'(abbreviated as W) seedlings grafted onto W, Cucurbita moschata ‘Quanneng Tiejia'(P1), ‘Kaijia No.1'(P2), and Lagenaria siceraria ‘Hanzhen No.3'(G), which were grown hydroponically. All the measured growth parameters were significantly inhibited by salt stress, with W/P2 exhibiting superior growth. Salt stress increased Na+uptake, which in turn disrupted K+/Na+homeostasis in all grafting combinations. The photosynthetic capacity, chlorophyll concentration, and photochemical efficiency of photosystem II of all grafts significantly decreased with salt stress. However, W grafted onto G and P2 showed higher resistance than W grafted onto W and P1. Electrolyte leakage(EL) superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase activity were significantly affected by both grafting and salt stress. Minimum EL was observed in W/P2, which also exhibited superior antioxidative capacity. Physiological and biochemical assessment indicated that W grafted onto the P2 rootstock displayed the greatest salt tolerance. Plants grafted onto salt-resistant P2 accumulated less Na+and reactive oxygen species(ROS) and exhibited superior growth,photosynthesis, and ROS-scavenging capacity compared to those grafted onto the other rootstocks.
