  fracture occurrence
Hip fracture occurrence was examined cross-sectionally in Japanese patients with rheumatoid arthritis (RA).
      
When FM, aLM/ht2, age, and time spent between fracture occurrence and DXA assessment were included together as the independent variables in a regression model, FM was the only independent variable significantly associated with BMD.
      
Soft tissue body composition and BMD were assessed by dual-energy X-ray absorptiometry (DXA), 23.2 ± 7.7 (mean ± SD) days after fracture occurrence.
      
Using digital X-ray radiogrammetry (DXR) on hand radiographs from a large population-based study, 1,370 postmenopausal women were evaluated in a prospective fashion; fracture occurrence was compared with DXR measurements of historic radiographs.
      
Before hip fracture occurrence, 52.8% of patients had never received any kind of treatment, and this figure reached 80% if we also included those who had taken only calcium and/or vitamin D.

Fatigue life and confidence analysis of offshore structure have been gra- dually used in engineering design stage.By reason of marine riser design,an efficient 2-D,large deflection,time domain mathematical model based on the so called lumped mass method has been developed. This paper which shows some new results is a continuation of the work presented on Offshore China’85 by the authors,Yi-Qing Sun and H.J.J. ven den Boom.It is emphasized that the value of extreme bending stresses along the riser during atochastic motion would not be higher than the value under the situation of the harmonic motion with large amplitude and high fre- quency,it implies that,in ordinary conditions,the fracture occurrence most- ly relates to the factors of fatigue. Statistic distrbution of bending stresses of time history from the mathe- matical model is also described in this paper,which is close to weibull’s the- oretical distribution.

疲劳和可靠度分析的设计方法已逐步被用于海洋工程领域,为了适应预报海上立管疲劳寿命的需要,一种有效的、以质量集点原理为基础的数字计算方法已获成功,该计算程序可以用来计算二维、大位移海上立管的时域动力特性.本文是文献[1]的继续,主要调强立管在随机运动条件下,立管弯矩应力沿轴线的分布及其统计分布.该文指出随机运动状态的立管弯矩应力不会出现如规则的较高频、较大位移运动条件下的较高的应力现象,说明立管裂纹的出现其主要原因是疲劳而致.分析所得的弯矩应力历时的极大值的统计分布比较接近于维泊尔(Weibull)的理论分布.

Regular variation of initial fractures' occurrences during obliquely superimposed -longitudinal bend folding has been studied by a positively deductive unfolding operation in this paper. The occurre recovered by using this operation to twice folded fractures have been compared with their initial occurrences. Some factors effected on this operation and their introduced evrors have been discussed. Finally, the correct methods has been proposed.

The pathological sections of the femora of 288 New Zealand rabbits arranged into guoupsand the result of torsion test showed that the dominant role of high intensity of "training"is to quickenbone stress reconstruction and intensify the ability to. resist fracture. The pathological sectiont exanina-tion of the upper parts of tibiae of 180 big rats which were seperated into therr groups and recived threekind of "training" as well as the observation under electron microscope showed a higher rate of accomplished reconstruction (14. 6% ) in the group of "intensdied cyclic training"than that in the other twogroups (which are 26. 1% and 21. 9% respectively) (P<0. 05). Beside, the group of "intensified cyclictraining" had a lower rate of stress fracture (11. 5%) than the other two groups (22. 9%) and 18. 8/00 re-spectively3 (P<0. 05).The authors also made sone prospective epidemiologic investigations among 1129recruits during the twelve weeks of basic militry training, and the results showed that the long tubiformbones of the lower limbs of the recruits experienced a period of stress remodeling reconstruction extendingabout eight weeks. The two peeks of stress fracture occurrence appeared in the second and the seventhweek and the occurrence of peaks may be advanced or delayed with the change of training intensity and du-ration. "Intensified cyclic training method" should adopted so as to decrease the rate of stress fracture occurrence in basic military trainig.

分组模拟训练的288只兔股骨标本病理观察及扭断试验结果表明,较大强度和时限训练的主导作用是加速骨塑形改建,增强抗骨折能力。分3组经3种方法训练的180只大鼠的胚骨上段病理切片及电镜观察表明,强化循环训练组的改建完成率(41.7%)高于其它两组(26.1%,21.9%),而应力性骨折发生率(11.5%)则低于其它两组(22.9%,18.8%)。对1129名新兵12周基础训练的前瞻性流行病学调查证实,下肢长管状骨经历约9周的应力性塑形改建期,训练的第2、7周出现的应力性骨折高发的双峰现象可随训练强度与时限的加大或减少,而提前或延迟出现。在训练中采用“强化循环训练法”将加速骨的塑形改建及降低应力性骨折发生率。
