目的评估英国中学高级水平考试成绩和智力是否能预测医生的职业未来业绩。设计20年后通过邮寄问卷随访进行前瞻性定群研究。地点伦敦的一所英国医学院。参加者 2002年1月进行随访的511名医师,他们是在1975至1982年进入Westminister医学院的临床医学生。主要结局测量指标在医院或全科医师中晋升不同职别所需要的时间;毕业后获得的资格,如执业医师资格(membership)／合作研究员职位(fellowship)、文凭、更高的学位;发表研究性文章的数量;进入医学院时与中学高级水平考试和智力测验结果(AH5)有关的压力和疲惫的评估;普通健康调查表;Maslach疲惫调查表;在随访时对职业满意度的调查表。结果 47名(9％)医生已经不在医师注册簿上。他们的中学高级水平考试级别低于仍然在册的那些医生(Pcox回归,P<0.001;b=0.376,SE=0.098,exp(b)=1.457)。智力测验不独立预测医生是否会脱离医师注册登记、职业结局或其他测量结果。中学高级水平考试不预测文凭或更高的学位资格、研究性出版物、压力或疲惫评估。然而,文凭、更高的学位及研究性出版物数量却与个性的衡量显著相关。结论在英国。

An attempt is made to study various types of multiplicity distributions and multiplicity correlations amongst secondary charged particles produced in 4.5 and 14.5 A GeV/c 28Si-nucleus interactions. The results reveal that multiplicity correlations of the type , where i, j = b, g, s and h with i ≠ j, are linear. The observed multiplicity correlations are nicely fitted by the method of least squares fitting of the type, = b + ani. Furthermore, the multiplicity distributions of relativistic charged particles and compound multiplicity at 4.5 A GeV/c are nicely fitted by Poisson distributions with peaks at relatively lower multiplicities. However, in the case of multiplicity distributions of various types of secondary charged particles produced in 14.5 A GeV/c 28Si-nucleus collisions definite trends are not discernible.

世界核心医学期刊文摘（皮肤病学分册） 2006年第12期2卷 14-15页

作者： Gottschling M. Roewert J. i. Nindl 周少娜 Department of Dermatology Skin Cancer Center Charité University Hospital of Berlin Berlin Germany

Background: Tenascin-c (Tn-c) is an extracellular matrix protein with multiple functions that is present at low levels in normal tissues, but which is highly present in various tumours. The mRNA expression and protein level of Tn-c including its various isoforms have not been investigated comprehensively so far in cutaneous squamous cell carcinoma (Scc) and the precursor lesion actinic keratosis (ak). Objectives: To assess the dysregulated expression and splice variants of Tn-c in cutaneous squamous cell dysplasia and carcinoma. Methods: Biopsies from 66 patients (or representative subsets) that comprised 25 specimens from normal skin, 19ak and 22 cutaneous Scc were analysed for Tn-c splice variants using splice-specific primers. The amount of Tn-c mRNA was investigated by quantitative real-time reverse transcription-polymerase chain reaction. in addition, the presence of Tn-c protein was analysed in sections of paraffin-embedded tissues using immunohistochemistry. Results: The large Tn-c splice variant was present in only 5%of normal skin samples, in comparison with 63%of ak (P cc (P c mRNA expression was significantly increased in ak and Scc compared with normal skin (P corresponding proteins were rarely detected in cells of the vascular epithelial layers and perifollicular layers of some normal skin specimens, and their spatial localization expanded into the papillary dermis of ak. The largest amount and the widest distribution were found in samples of Scc, in which Tn-c was located in the basal cells at the tumour invasion front and additionally in the papillary dermis and reticular dermis. conclusions: Tn-c is present in the dermis, its expression is increased during skin cancer development, and the large splice variant is characteristic for ak and Scc, which may prove useful for diagnostic approaches in cutaneous Scc.

Photovoltaic solar thin films zinc telluride studies on chemically deposited have been carried out to assess its suitability for use in the conversion of solar energy to electrical energy. The configuration of fabricated cell is n-ZnTe| NaOH (0.1M) + S (0.1M) + Na2S (0.1M)|C(graphite). The study shows that ZnTe thin films are n-type conductivity. The junction ideality factor was found to be 2.87. The flat band potential is found to be -0.652 V. The barrier height value was found to be 0.583 eV. The study of the power output characteristic shows open circuit voltage, short circuit current, fill factor and efficiency were found to be 150 mV, 25.6 μA, 24.86% and 0.49%, respectively. The photovoltaic cell characterization of the thin films is carried out by studying current-voltage characteristics in dark, capacitance-voltage in dark, barrier height measurements, power output characteristics.

为阐明磁性离子在不同替代位置对YBcO体系超导电性的影响机制 ,利用正电子湮没及相关实验手段结合数值模拟 ,系统研究了Fe和Ni掺杂的YBa2 cu3O7-δ体系 .结果表明 ,Fe和Ni离子在替代过程中均以离子团簇的形式进入晶格 .当离子进入cuO2 面时 ,由于团簇改变了周围的电子结构 ,造成电子的局域化 ,并直接影响了电子对的配对和输运 ,因而强烈抑制了体系的超导电性 .而当掺杂离子进入cu_O链区时 ,它们同样通过团簇的形式改变周围的电子结构 ,并抑制空穴载流子的产生及其向cuO2 面区域的有效转移 ,造成载流子的局域化 ,弱化了载流子库的功能 ,然而由于它们仅间接影响了超导电子对的配对和输运 ,因此对超导电性的抑制较弱 .实验结果同时显示。
