this paper discussed several untestable assumptions which were often used in epidemiologi-cal observational studies,and some paradoxical results that may arise under different assumptions were showed.simpson's paradox and lord's paradox were introduced.assumption of treatment assignment in causal inference of epidemiological studies,assumption of control group in evaluation of exposure ef-fects,and assumption of missing data mechanisms in incomplete data analysis were also discussed.

本文主要讨论流行病学观察性研究中几种常用的假定，介绍simpson's悖论和lord's悖论，逆回归问题，以及在不同假定下可能出现的相互矛盾的结果。探讨流行病学研究的因果推断中处理分配机制的假定，暴露作用评价中对照组的模型假定，以及不完全数据分析中缺失数据机制的假定。

Current studies focus on the image rectification or image unwarping for a single-view-point omni-camera. Studies on non-SVP ones are limited because of the difficulty to analyze their structures.

但因非单一视点摄影机具有比单一视点较好之平均径向解析度及视野较大之优点，使其更适合应用於上述之领域。

"Recent studies on the autoimmune origin of vitiligo also emphasize the probable implication of the immunosuppressive action of UV therapy in the repigmentation of vitiliginous plaques," the authors note."acrolimus, a new topical immunosuppressive drug developed for the treatment of atopic dermatitis, has shown some interesting results in treating vitiligo in 2 prospective studies."

研究人员指出，最近对於白斑自体免疫来源的实验，也强调了UV疗法的免疫抑制作用对於白斑再色素化可能的应用；Tacrolimus，一种新的局部免疫抑制药物，被开发用於治疗异位性皮肤炎，已经被两项前瞻性试验受瞩目的结果证实可以治疗白斑。

Both long-term followup studies and further large studies of whole body cooling are in progress.

长期的随访研究和全身降温的大型进一步研究都在进行中。

Several investigators have determined that placing the electrode parallel rather than perpendicular to the target nerve substantially increases the size of the lesion, thereby reducing the likelihood the treatment will miss or only partially coagulate the target nerve.234,235 After a literature review and cadaveric study, Lau et al.234 concluded the ideal electrode position is across the lateral neck of the superior articular process rather than the groove formed at the angle of the superior articular and transverse processes, as was used in most studies.159,160Other investigators have found the maximal lesion size to be reached within 60 s of lesion time,235–237 independent of whether the system is temperature or voltage controlled.238 Studies conducted in human myocardium have determined that irrigation fluid has either no effect or a slightly beneficial effect on lesion size.239 Hence, the use of LA to prevent procedure-related pain or steroid to reduce the incidence of neuritis184 should theoretically have no adverse effects on the efficacy of radiofrequency denervation.

一些研究者认为，将点击平行的置于目标神经比将其垂直置于目标神经增加了消融的范围，因而减少损伤可能使目标神经不被或部分被消融。Lau等回顾了文献中对尸体的研究，总结出理想的电极放置位置为上关节突颈部外侧而非常采用的上关节突与横突形成的沟。其他学者研究发现，不论系统是温度控制或电压控制，其最大的损伤范围都在60秒内达到。在心肌灌注的研究中，灌注液多损伤范围造成轻微或不造成损伤。因此，使用LA预防过程相关性疼痛或类固醇防止神经炎发生时，需理论上确保对射频消融效果无副作用。

According to the Hong Kong Police Crime Prevention Bureau, case studies indicate that most burglars are scared off by the presence of an alarm system, and police studies show that electronically secured homes are five to six times less likely to be burglarized than unprotected homes.

DATA SYNTHESIS: Although there are some differences in the results between human studies and animal studies about the change of bone mineral density after detraining or reducing exercise, both of them get the same conclusion, that is, the bone mass gained by exercise in growth period will be maintaining if persisting appropriate exercise after detraining training.
