This study investigated the effects of dietary arginine （Arg） supplementation, just during lactation, on sow and litter per- formance, plasma concentrations of metabolites and hormones, and milk yield and composition in multiparous sows. Thirty-one sows were randomly assigned to 3 dietary treatments supplemented with 0.0 （control, n=10）, 0.5% （n=10）, or 1.0% （n=11） L-Arg-HCI, respectively. Experimental diets were provided to the sows from d 3 to 21 of lactation. Plasma and milk samples were collected at d 14 and 21 of lactation. The average daily gain （ADG） of piglets from sows fed diets supplemented with 0.5 or 1.0% L-Arg-HCI at d 3 to 14 of lactation, were higher than that of controls （P〈0.05）. Maternal supplementation with 1.0% L-Arg-HCI also increased ADG of piglets between d 3 and 21 of lactation than that of the controls （P〈0.05）. There was no significant effect of supplementation on average daily feed intake （ADFI）, body weight loss, and backfat thickness loss of lactating sows. Supplementation with 0.5 or 1.0% L-Arg-HCI had a trend towards increasing milk yields and milk fat contents （0.05〈P〈0.10）; milk protein and lactose were unchanged. Supplementation with 1.0% L-Arg- HCI increased plasma concentrations of prolactin and insulin in sows at d 14 and 21 of lactation, and plasma concentrations of non-esterified fatty acid （NEFA）, insulin-like growth factor-1 （IGF-1）, and nitric oxide （NO） in sows at d 21 of lactation, when compared to the controls （P〈0.05）. Supplementation with 1.0% L-Arg-HCI increased IGF-1 and spermine in milk at d 14 of lactation, relative to the controls （P〈0.05）. Plasma Arg concentrations at d 14 and 21 of lactation, as well as plasma NO level and milk IGF-1 at d 21 of lactation, were increased, while plasma urea nitrogen （PUN） concentration at d 14 and 21 of lactation was decreased, by supplementation with 0.5 or 1.0% L-Arg-HCI when compared to the controls （P〈0.05）. Collectively, dietary supplementation of multiparous sows with Arg, ju

Chinese Medical Journal 2011年第6期124卷 954-955页

作者： yi Fu SHEN Min WU Feng WANG Hai-chang guo Wen-yi LI Wei-jie LIU Bing Department of Cardiovascular Medicine Xijing Hospital Fourth Military Medical University Xi'an Shaanxi 710032 China

Technologies associated with cardiac resynchronization therapy （CRT） devices and lead systems have ***, dislocation after coronary sinus （CS） lead placement continues to be a problem. We reported on the patient treated with CRT, in whom dislocation of CS lead occurred. In the case, we tried to reposition the CS lead without the left heart delivery system only using pre-shaped stylet and guidewire, and the dislocated CS lead could be successfully repositioned by the method. The method of only using a pre-shaped stylet and guidewire is easier than the conventional way, and it can shorten procedure duration and fluoroscopy time, as well as reduce the cost of treatment, but it is not always feasible.

日常生活实践推动着非遗传承观念的更新和传承范式的转换,不断生成新的传承关照和传承话语,促使非遗传承的问题域从技艺技能和文化特质向“何以支撑人之生”的生存发展问题以及“何以蕴含人之本质”的文化生活问题方面扩展。随着田野调查的深入以及对相关问题的反思,认为当下对非遗传承的问题域扩展进行研究应探讨四个不断递进而又互相包含、彼此建构的问题。第一,传承在当代中国的话语表达是非遗传承的一个基本问题,回应着“原生态”的构想和活态传承的追求,使得文化时代下非遗传承的旨归和三层关切得以明晰。第二,传承何以有效涉及到传承与生存和生活的距离,成为非遗传承的路径和动力问题,复现着传承作为一种文化生命、一种文化生活的内涵与方式。第三,将前两层问题进一步映射到传承人身上,传承人含义的双重性构成了非遗传承的主观愿景和客观现实问题,体现着非遗的一种文化生存方式。第四,非遗传承的问题域本身具有生命张力和系统整体性,各个问题并非割裂散落存在,而是互动建构着非遗的传承生态问题。社会传承作为非遗传承生态的一个生动体现,需要给予更多的关注和思考。

Biomedical and Environmental Sciences 2016年第6期29卷 398-407页

Objective This study was designed to evaluate the prevalence of thyroid nodules（TNs） and its relationship with urine iodine concentrations（UICs） after the regional rapid economic growth and lifestyle changes. Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine（T3）, tetraiodothyronine（T4）, serum thyroid stimulating hormone（TSH）, free triiodothyronine（FT3）, free tetraiodothyronine（FT4）, thyroglobulin antibody（Tg Ab）, thyroid peroxidase antibody（TPOAb）, and TSH receptor antibody（TRAb） levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs（P=0.0035, P=0.0068）. The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs（P=0.0164, P=0.0127）. The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was 〈140 μg/L and 〉400 μg/L. Very low or high UIC levels need attention and correction.

职业病防治工作不仅是社会关注热点问题,也是公共卫生领域的重点工作。防治职业病,保护和促进劳动者健康,是职业卫生工作的最终目标,而职业卫生监测是连接疾病与预防的重要桥梁。职业卫生监测所反馈的信息,对职业病防治工作具有重要的指导作用。在近二十年里,对职业卫生监测的关注度大大增加,这一方面是得益于政府部门对工业化发展和公共卫生能力建设的重视,同时也是由于劳动力资源紧缺、用工成本增加、劳动者赔偿成本增高、人口老龄化等诸多现实因素的刺激作用。

One of the primary goals of space-borne gravitational wave detectors is to detect and analyze extreme-mass-ratio inspirals(EMRIs). This task is particularly challenging because EMRI signals are complex, lengthy, and faint. In this work, we introduce a2-layer convolutional neural network(CNN) approach to detect EMRI signals for space-borne detectors, achieving a true positive rate(TPR) of 96.9% at a 1% false positive rate(FPR) for signal-to-noise ratio(SNR) from 50 to 100. Especially, the key intrinsic parameters of EMRIs such as the mass, spin of the supermassive black hole(SMBH) and the initial eccentricity of the orbit can also be inferred directly by employing a neural network. The mass and spin of the SMBH can be determined at 99% and 92% respectively. This will greatly reduce the parameter spaces and computing cost for the following Bayesian parameter *** model also has a low dependency on the accuracy of the waveform model. This study underscores the potential of deep learning methods in EMRI data analysis, enabling the rapid detection of EMRI signals and efficient parameter estimation.
