Post-traumatic stress disorder (PTSD) and alcoholism are highly comorbid in humans and have partially overlapping symptomatic profiles. The aim of these studies was to examine the effects of traumatic stress (and stress reactivity) on alcohol-related behaviors and neuronal activation patterns. Male Wistar rats were trained to respond for alcohol, were exposed to predator odor (bobcat urine) paired with context and were tested for short- and long-term avoidance of the predator odor-paired context, alcohol self-administration and compulsivity of alcohol responding. Rats were re-exposed to the odor-paired context for western blot analysis of ERK phosphorylation in subregions of the medial prefrontal cortex (mPFC) and the amygdala. Rats that avoided the predator-paired chamber (Avoiders) exhibited persistent avoidance up to 6 weeks post conditioning. Avoiders exhibited increases in operant alcohol responding over weeks, as well as more compulsive-like responding for alcohol adulterated with quinine. Following re-exposure to the predator odor-paired context, Avoiders and Non-Avoiders exhibited unique patterns of neuronal activation in subregions of the mPFC and the amygdala, which were correlated with changes in avoidance and alcohol drinking. Furthermore, activity of upstream regions was differentially predictive of downstream regional activity in the Avoiders versus Non-Avoiders. An animal model for assessing the effect of traumatic stress on alcohol drinking reveals individual differences in neuronal activation patterns associated with re-exposure to traumatic stress-related stimuli, and may provide insight into the neural mechanisms underlying excessive alcohol consumption in humans with PTSD.  相似文献

Background: MicroRNAs (miRNAs) are small non‐coding RNAs with regulatory functions as tumour suppressors and oncogenes. Although single nucleotide polymorphism (SNP) in miRNA regions have been reported to be rare and unlikely to be functionally important, recent evidence suggested that rs11614913 SNP in miR‐196a2 was associated with the susceptibility of lung cancer, breast cancer, congenital heart disease and shortened survival time of non‐small‐cell lung cancer. Aims: The aim of this study was to investigate the association between this genetic variant and the risk and/or progression of colorectal cancer (CRC). Methods: A total of 126 CRC patients and 407 healthy controls was periodically enrolled. DNA was extracted from blood specimens, and miR‐196a2 polymorphism was genotyped by polymerase chain reaction–ligation detection reaction (PCR–LDR). Results: Although the frequency of CC homozygotes or miR‐196a2C allele‐containing genotypes (CT and CC) was lower in CRC patients than in the healthy controls, no significant association between miR‐196a2 polymorphism and the risk of CRC was found. The frequency of the ‘C’ allele in CRC patients was also not significantly lower than in healthy controls. In a subsequent analysis of the association between this polymorphism and the progression of CRC, there was still no significant difference in both genotype and allelic frequency. Conclusions: Our results suggest that miR‐196a2 polymorphism is not associated with both an increased risk and progression of CRC in Chinese.  相似文献

The influence of the mother tongue on vowel productions in infancy is different for deaf and hearing babies. Audio material of five hearing and five deaf infants acquiring Dutch was collected monthly from month 5–18, and at 24 months. Fifty unlabelled utterances were digitized for each recording. This study focused on developmental paths in vowel productions. The applied automated band filtering analysis is F0‐independent and results in a spectral envelope, sampled in a 40‐dimensional space. Via a Principal Component Analysis (PCA, data reduction), a vowel space for normally hearing 2‐year‐olds was constructed, enabling the projection of the individual developmental data of the infants in a two‐dimensional reference plane. Comparison of the results for the hearing and the deaf infants over 2 years indicates individual as well as group differences. The amount of hearing loss as well as the communication styles seem to be important factors in explaining differences between the infant categories.  相似文献

This study aimed to analyze the intra‐individual variation in VO2max of human subjects using total‐capture and free‐flow indirect calorimetry. Twenty‐seven men (27 ± 5 year; VO2max 49‐79 mL?kg?1?min?1) performed two maximal exertion tests (CPETs) on a cycle ergometer, separated by a 7 ± 2 day interval. VO2 and VCO2 were assessed using an indirect calorimeter (Omnical) with total capture of exhalation in a free‐flow airstream. Thirteen subjects performed a third maximal exertion test using a breath‐by‐breath calorimeter (Oxycon Pro). On‐site validation was deemed a requirement. For the Omnical, the mean within‐subject CV for VO2max was 1.2 ± 0.9% (0.0%‐4.4%) and for ergometer workload P max 1.3 ± 1.3% (0%‐4.6%). VO2max values with the Oxycon Pro were significantly lower in comparison with Omnical (P < 0.001; t test) with mean 3570 vs 4061 and difference SD 361 mL?min?1. Validation results for the Omnical with methanol combustion were ?0.05 ± 0.70% (mean ± SD; n = 31) at the 225 mL?min?1 VO2 level and ?0.23 ± 0.80% (n = 31) at the 150 mL?min?1 VCO2 level. Results using gas infusion were 0.04 ± 0.75% (n = 34) and ?0.99 ± 1.05% (n = 24) over the respective 500‐6000 mL?min?1 VO2 and VCO2 ranges. Validation results for the Oxycon Pro in breath‐by‐breath mode were ‐ 2.2 ± 1.6% (n = 12) for VO2 and 5.7 ± 3.3% (n = 12) for VCO2 over the 1000‐4000 mL?min?1 range. On a Visual analog scale, participants reported improved breathing using the free‐flow indirect calorimetry (score 7.6 ± 1.2 vs 5.1 ± 2.7, P = 0.008). We conclude that total capturing free‐flow indirect calorimetry is suitable for measuring VO2 even with the highest range. VO2max was linear with the incline in P max over the full range.  相似文献

中医临证四大核心理念之制宜观   总被引:1,自引:0,他引:1  
人体是一个开放的复杂巨系统,与自然、社会无时无刻、无处不在地发生联系。中医学认为,疾病的发生、发展与转归受多方面因素的影响,如体质、年龄、性别、时令气候、地理环境等。因而在治疗上须依据疾病与患者、地理、气候三者之间的关系,制定相适宜的治疗方法,即因人制宜、因地制宜、因时制宜,才能取得预期的治疗效果。制宜观是指导中医临证的重要观点,是基于整体观念,以追求人体内外环境协调平衡为目标而形成的一种精准治疗原则。  相似文献

目的  探讨联合微信群的个体化健康教育对2型糖尿病(T2DM)患者认知功能的影响。方法  53例T2DM患者,男性30例,女性23例,应用重复成套神经心理状态测验(RBANS)量表评价患者认知功能,对患者进行院内宣教、院外随访及电话随访等个体化健康教育,联合微信群进行教育,干预6个月后,观察T2DM患者教育前后空腹血糖、糖化血红蛋白及认知功能的变化,探讨认知增值的相关因素。结果  联合微信群的个体化健康教育后的空腹血糖(FPG)、糖化血红蛋白(HbA1c)值低于教育前(P <0.05);联合微信群的个体化健康教育后的延迟记忆评分(86.9±13.5 vs 80.4±14.9)高于个体化健康教育前(P <0.05);经6个月联合微信群的个体化健康教育后,HbA1c下降值与延迟记忆升高值呈正相关(r =0.353,P =0.020),与重复成套神经心理状态测验标准分升高值呈正相关(r =0.327,P =0.045)。线性回归分析后,HbA1c下降值与延迟记忆升高值的相关关系仍存在(P <0.05)。结论  联合微信群的个体化健康教育能明显改善T2DM患者认知功能,尤其在延迟记忆方面。

Over the last decades, the disability movement has been advocating for a paradigmatic shift in how disability is perceived and managed: from a medical or individual perspective focusing on the person's body and mind to a social perspective emphasizing the context and barriers of disability. However, we still know little about the perceptions of helping professionals, particularly social workers who work closely with disabled people. Thus, the aim of the current study is to develop and validate a scale—Perceptions Toward Disability Scale (PTDS)—to measure how social workers view disability: as an individual or social category. This paper describes the three phases of the scale's construction. First, scale items were formulated and its content validity was examined. Next, a pilot of 30 social workers completed a questionnaire and an initial exploratory factor analysis was conducted. In the third and main phase, the final draft was completed in 2016 by 565 Israeli social work students to assess its psychometric properties. Both exploratory and confirmatory factorial validity and discriminant validity analyses were conducted. The results of a confirmatory factor analysis revealed two distinct factors: an individual perspective of disability comprised of eight items (α = 0.77) and a social perspective of disability comprised of ten (α = 0.66). Subsequent analyses supported the scale's discriminant validity as indicated by the lack of an association between the Attitude Toward Disabled Persons Scale (ATDP) and the social model subscale (r = .13, p = .19) and by the weak negative relation with the individual model subscale (r = ?.25, p = .01). These findings show that the PTDS possesses promising construct validity and provide support for its utility. This easy‐to‐administer instrument offers several practical benefits and can serve as a framework for further empirical research regarding social work practice with disabled people.  相似文献
