目的探讨青少年特发性脊柱侧凸的患者在包括手法在内的综合治疗前后的脊柱旁肌电活动特点。方法选择9例确诊的特发性脊柱侧凸的患者,在乳突下、c1、T1、T3、T6、T9、T12、L3、L5位置记录为期24周的综合治疗前后的椎旁的肌电活动。结果在综合治疗前:7例上位凸起的对侧枕下肌电活动过高;6例下位凸起侧的L5/S1段肌电活动过高;6例从c5到L3单侧肌电活动过高。所有患者过高肌电活动发生在两弯曲中的一个的凹侧。综合治疗后:左右枕下SEMG值对称。上位或下位弯曲的SEMG值要么对称,要么在凸侧肌电活动过高。同侧L5/S1的SEMG值与下位弯曲凸侧一样。对治疗前后的SEMG值进行配对T检验,P<0.001。在前两周,患者过高肌电活动抑制很明显。经过7周的治疗,从凹侧至凸侧的过高肌电活动的交换在所有患者都明显并保持到治疗结束。结论综合治疗可以使凹侧的肌电活动过高转变为双侧平衡或凸侧肌电活动过高时,弯曲发展可以被阻止。一旦平衡建立,弯曲的阻止和活动的交换就会贯穿整个治疗过程。

Comparative Immunology of 5 bird species: Differences betwee...

23rd International Ornithological congress

作者： Alexander Scheuerlein Kevin D.Matson raymond Peng Kirk c.Klasing Princeton University NJ USA University of Missouri St Louis USA University of california Davis USA University of california Davis USA

＜正＞ In an attempt to assess comparative aspects of the immune system across taxa we subjected male individuals of 5 different bird species （Mallard, Japanese Quail, Golden Pheasant, cockatiel, Zebra Finch） to a common protocol to assess immunocompetence. We either challenged the birds with PHA, a commonly used lectin, or cFA, an agent mimicking a bacterial infection. Birds challenged with PHA showed a higher clearance of plasma zinc after 24 hours than birds infected with cFA, indicating a greater inflammatory response. Moreover, the birds showed species specific differences in the surge of acute phase proteins, different titers of natural antibodies and differences in the recruitment and activation of macrophages as tested in a chemotaxis assay. The potential of our approach to understand the diversification of life histories will be discussed.

背景:精神分裂症存在情感体验和表达障碍。然而,大多数以往研究往往只局限于情感体验(尤其是快感缺乏)或只针对表达。较少有同时研究精神分裂症患者情感体验和表达。目的 :本研究旨在考察精神分裂症患者的快感体验和情感表达。尤其是,特别关注精神分裂症患者的情感障碍(包括快感体验和表达)和阴性症状之间的关系。方法 :150例患者完成了愉快情绪体验量表(Temporal Experience of Pleasure Scale)和情感表达量表(Emotional Expressivity Scale)的评估。结果 :精神分裂症患者表现出快感缺乏,但情感表达的能力完整。以阴性症状为主的精神分裂症患者在期待性愉快体验,尤其是抽象性期待愉快体验上的缺损更为明显结论:研究结果表明,精神分裂症患者存在出快感缺乏,但他们表达情感的能力似乎完好无损。快感缺乏尤以阴性症状为主的精神分裂症患者更为突出。

Open Journal of Urology 2013年第4期3卷 173-178页

Aim: To establish norms for reproductive hormones in healthy males with normal urologic and sexual function, and to assess the change in reproductive hormone levels with respect to age among healthy males. Methods: Healthy volunteers aged 18 - 29 (group 1) and 45 - 65 (group 2) were recruited for enrollment in a prospective study. Inclusion criteria comprised normal urinary, ejaculatory, orgasmic, and erectile function, as determined by IPSS, MSHQ, and IEFF-15. Men with history of chronic medical illnesses or chronic medication use were excluded. Fifty men met the study criteria. Each participant underwent physical examination and standardized serum hormone evaluation using ELISA and EIA methods. Statistical analysis was performed using JMP 8.0 software (SAS Institute Inc., cary, Nc), to compare hormone levels between the two groups of men. Results: There were 25 men each in groups 1 (mean age 26) and 2 (mean age 51). Overall, 46% were caucasian, 31% African American, 15% Hispanic, and 8% Asian. There was no statistically significant difference in serum total T, SHBG, E2, or LH between groups 1 and 2. Notably, the 95% cI for serum T levels for both groups of men were considerably higher than commonly accepted lower-end cut-off limits. conclusion: Serum T levels do not vary significantly with age, in otherwise healthy men with normal sexual and urologic function. Furthermore, healthy men have much higher serum total and free T levels than the lower-end reference limits provided by commercial laboratories.

Two rotary furnaces of different construction model were used for the research work. One has no recuperating system and the second one has recuperating system. 60 kg of grey cast iron scrap was charged into each of the furnaces at different time, after preheating the furnaces for 40 minutes. 0.5 kg graphite and 0.2 kg ferrosilicon were charged along with the scrap. The theoretical charge calculations have the composition of the melt as 4.0% carbon and 2.0% silicon. charges in the furnaces were heated to obtain molten metal suitable for casting at 1350°c. The content of the furnaces was tapped three times after the attainment of 1350°c with 15 minutes interval between each tapping. Optical light emission spectrometer was used to analyze the resulting composition of the tapped samples. For type A furnace (without recuperation), sample A has its carbon and silicon contents reduced compared to expected value by 25.5% and 10.8%, sample B reduced by 29% and 13.4% and sample c reduced by 32% and 17.0% respectively. In Type B furnace (with recuperation), sample D has its carbon and silicon contents reduced by 12.2% and 7.3%, Sample E reduced by 13.0% and 8.0% and sample F reduced by 13.9% and 8.9% respectively.

The improved Dirac equation is completely solved in the case of the hydrogen atom. A method of separation of variables in spherical coordinates is used. The angular functions are the same as with the linear Dirac equation: they account for the spin 1/2 of the electron. The existence of a probability density governs the radial equations. This gives all the quantum numbers required by spectroscopy, the true number of energy levels and the true levels obtained by Sommerfeld’s formula.
