目的以反刍思维和生活满意度量表测验工具为依托,调查非自杀性自伤行为青少年患者关于反刍思维与生活满意度的现状,为分析相关因素和制订积极的心理干预方案提供参考资料。方法采用积极和消极反刍思维量表(positive and negative rumination scale,PANRS)和青少年学生总体生活满意度量表(adolescent students’life satisfaction scale,ASLSS)作为评价工具,对2022年11月—2023年5月福州某三甲精神病院心理科住院的30例有非自杀性自伤行为的青少年患者(研究组)与无自杀性自伤行为正常在校学习的青少年作为对照组进行测评,对量表结果进行分析与探讨。结果研究组积极因子(享受快乐和积极应对)评分低于对照组,消极因子(抑制快乐、否定自我、消极归因)评分高于对照组(P<0.05)。研究组总体生活满意度评分为(119.00±36.19)分,低于对照组的(156.00±34.66)分,差异有统计学意义(P<0.05)。结论非自杀性自伤行为青少年患者存在明显的积极反刍思维缺陷,较强的消极反刍思维,严重影响青少年对生活满意的程度。可以通过制订提高积极的反刍思维的干预措施有利于提高青少年未来生活的积极性。

Oxygen surface exchange and oxygen chemical diffusion coefficients of LaNi_(0.4)Fe_(0.6)O_(3-δ)ceramics are determined via conductivity relaxation method after stepwise change of temperature in the range of 700-950℃in air and Ar/O2 gas flow at oxygen partial pressures(p_(o2))of 4 Pa,18 Pa,37 Pa,47 Pa and 59 *** highest conductivity(about 160 S·cm^(-1))is found at 950℃in *** oxygen exchange(δ=0)below 700℃is observed in the investigated p_(o2) *** oxygen exchange coefficients determined in reduction mode are higher than those determined in oxidation *** is explained by clusterization of oxygen vacancies on the surface of the sample investigated in oxidation *** opposite tendency is found for chemical diffusion *** surface,the oxygen vacancies of the volume region are probably not clustered and have predetermined the higher oxygen diffusion mobility of the sample treated in oxidation mode.

In recent years,biochar has attracted considerable attention for soil quality improvement and carbon sequestration due to its unique physicochemical ***,the mechanism by which biochar application negatively affects the growth of crop seedlings has not been fully *** this study,a hydroponic experiment was conducted to evaluate the response of rice,wheat,and corn seedlings to biochar application(CK,0 g/L;BC1,0.5 g/L;and BC2,1.0 g/L).Compared with the CK treatment,the BC1 and BC2 treatments decreased the fresh shoot and root weights of rice and corn seedlings(P0.05).For the contents of nutrient elements in seedlings,both BC1 and BC2 treatments hindered the roots from absorbing Fe and Cu and increased the uptake of Ca and *** with the CK treatment,the translocation factor(TF)values of Ca,Mn,and Zn were significantly decreased especially in rice seedlings(35.3%-36.8%,68.7%-76.5%,and 29.8%-22.0%,respectively)under the BC1 and BC2 treatments,while only Mn was significantly decreased in wheat and corn seedlings(P<0.05).Transmission electron microscope(TEM)analysis of root cross-sections showed that nano-sized biochar particles(10~23 nm)were found in the root cells under BC2 treatment *** findings reveal that a large amount of biochar application can reduce nutrient absorption and translocation,and hinder rice,wheat,and corn seedlings,particularly rice seedling,in hydroponic system.
