论《鸳鸯针》的思想倾向     

秦良 《江西教育学院学报》2003,24(1):95-99

《鸳鸯针》是一部针对明末社会腐败现象痛下针砭的拟话本小说,它通过具体的人物和故事,揭露了科场的腐败、官场的腐败、商界的腐败以及下层社会风气的败坏。作者开出的药方首先是在选拨人才方面不必迷信科举,让绿林中人也为国家效力,其次是要求官员正直廉明,宽厚仁恕,以德报怨,感化坏人;再次是提倡诚实守信,反对损人利巳;提倡贞洁,反对纵欲。他对社会的揭露是有力的,但他开出的药方几乎是无用的。  相似文献

Objective: To investigate the influence of lead exposure on the immune function of lymphocytes and erythrocytes in preschool children. Materials and methods: A group of 217 children three to six years of age from a rural area were given a thorough physical examination and the concentration of lead in blood samples taken from each subject was determined. The indices of lymphocyte immunity (CD 3CD 4, CD 3CD 8, CD 4CD 8, CD-3CD 19) and erythrocyte immunity (RBC-C3b, RBC-IC, RFER, RFIR, CD35 and its average fluorescence intensity) of 40 children with blood lead levels above 0.483 μmol/L were measured and compared with a control group. Results: The blood lead levels of the 217 children ranged from 0.11 μmol/L to 2.11 μmol/L. The CD 3CD 4and CD 4CD 8 cells were lower (P＜0.01) and the CD 3CD 8 cells were higher in the lead-poisoned subjects than those in the control group (P＜0.05). CD 3 and CD-3CD 19 did not show significant differences. Although the RBC-C3b rosette forming rate was lower and the RBC-IC rosette forming rate was higher in the lead-poisoned group, this difference could not be shown to be statistically significant (P＞0.05). RFIR was found to be lower in the lead-poisoned group (P＜0.01). Compared with the control group, the positive rate of CD35 was not found to be significantly different in a group of 25 lead-poisoned children (P＞0.05), while the average fluorescence intensity was lower in the lead-poisoned group (P＜0.05). Conclusion: Lead exposure can result in impaired immune function of T lymphocytes and erythrocytes in preschool children.  相似文献

Conditional and indirect effects of age of first exposure on PTSD symptoms     

《Child abuse & neglect》2016

Childhood violence exposure (CVE) in formative developmental years may have potent effects on severity and complexity of post-traumatic stress symptoms (PTSS) in adulthood, yet little research has examined the role of age of first exposure in the context of polyvictimization or gone beyond an examination of direct effects. The current study examines the specific associations between age of first exposure, total CVE, and posttraumatic stress symptoms in adulthood. Further, the conditional and indirect effects of age of first exposure on posttraumatic stress symptoms were examined. We hypothesized that age of first exposure to violence would be associated with higher total violence exposure across childhood, thereby predicting current posttraumatic stress symptom severity (i.e., indirect effect). We also postulated that age of first exposure would affect the relationship between total violence exposure and posttraumatic stress symptoms such that earlier exposure would exacerbate the effects of violence exposure (i.e., conditional effect). Participants included 269 violence-exposed adults recruited through MTurk; the mean age of first CVE was 6 years (SD = 3.29). Conditional process models indicated that age of first exposure was significantly associated with higher total childhood violence exposure, which in turn, was significantly associated with current posttraumatic stress symptoms in all domains. Further, a conditional effect of age of first exposure was present such that the relationship between total exposure to violence and symptoms of hyperarousal was stronger for those first exposed at earlier ages. Findings provide support suggesting the particular potency of early trauma on regulatory response systems.  相似文献   

低氧反复冲刺训练在团队项目中的应用及研究进展     

邱俊强 《成都体育学院学报》2020,(2):114-118,126

低氧反复冲刺训练是近年来兴起的新的低氧训练方法,已在多个团队项目中使用。在低氧环境下进行反复冲刺训练,运动员由于受到更强的负荷刺激而产生相应的代谢适应,从而有利于改善机体的反复冲刺能力、间歇有氧运动能力及疲劳指数。文章从目前高原/低氧训练方法多样化入手,介绍了低氧反复冲刺训练方法的提出、在团队项目中的应用及其提升运动表现的可能机制。研究表明,低氧反复冲刺训练的有效性可能与提高运动肌的氧气利用率、提升磷酸肌酸再合成能力以及改变神经肌肉功能等因素有关。本文还对低氧反复冲刺训练的应用前景进行了展望。  相似文献   

The association between child exposure to intimate partner violence (IPV) and perpetration of IPV in adulthood—A systematic review     

《Child abuse & neglect》2018

Increasingly recognized as a distinct form of childhood maltreatment, children’s exposure to intimate partner violence (IPV) has been shown to be associated with an array of negative psychosocial outcomes, including elevated risk for additional violence over the life course. Although studies have identified child exposure to IPV as a predictor of IPV perpetration in adulthood, no review has critically evaluated the methodology of this quantitative work. The present study examines the association between childhood exposure to IPV and the perpetration of IPV in adulthood based on a systematic review of the literature from inception to January 4, 2016. Databases searched included Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, Sociological Abstracts and ERIC. Database searches were complemented with backward and forward citation chaining. Studies were critically appraised using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 5601 articles identified by the search, 19 studies were included for data extraction. Sixteen of these studies found that child exposure to IPV was significantly and positively associated with adult IPV perpetration; three studies reported null findings. The methodological quality of the studies was low. Work thus far has tended to focus on child exposure to physical IPV and the perpetration of physical IPV within heterosexual contexts. In addition, measures of child exposure to IPV vary in their classification of what exposure entails. We critically discuss the strengths and limitations of the existing evidence and the theoretical frameworks informing this work.  相似文献

Non-occupational lead exposure and hypertension in Pakistani adults     

Rahman S  Khalid N  Zaidi JH  Ahmad S  Iqbal MZ 《Journal of Zhejiang University. Science. B》2006,7(9):732-737

INTRODUCTION Blood-Pb levels are taken as representative of dose/exposure, as all clinical symptoms resulting from the toxic effects of Pb are manifested mainly in blood. Lead exposure of children correlates with de- creased IQ, symptoms of hyper kinesis or minima brain dysfunction, poor learning, or defects in specific neuromotor tasks (Landgrin et al., 1980). Large number of observations over the years has associated lead exposure with human diseases (McMichael and Johnson, 1982). Ca…  相似文献
