Purpose The aim of the study was to establish the optimum variable resistance(VR)intensity for loaded countermovement jump(LCmJ)to induce post-activation potentiation(PAP).methods Eleven male athletes(age 23±2.3 years,height 1.77±0.05 m,body mass 73.7±9.0 kg)attended one familiariza-tion and four testing *** performed their own pre-competition warm up before performing two countermove-ment jumps(CmJ)for baseline ***,they performed 2×3 unloaded(UCmJ)or loaded CmJ(LCmJ)with one of the three VR intensities,Orange(6.7±0.6 kg),Red(14.0±0.9 kg)and Blue(24.0±1.4 kg),in random order,before performing two more CmJ for post-test *** testing session was separated by at least 48 *** There was significant increase in jump height in all conditions(Pmp height between conditions(P>0.05).There were small to moderate effect when comparing Orange and the other *** force and velocity increased in Red(Pmp height was significantly correlated to change in peak velocity(r=0.46,P=0.002)and peak power(r=0.46,P=0.002).Conclusion The findings of the study showed that UCmJ and LCmJ were effective in improving jump height acutely,and an intensity level of about 10%body weight contributed by VR seems to be the optimum resistance level.

Choroidal and skin metastasis of colon cancer is rare. In women, the frequency of cutaneous metastasis from colon cancer as the primary lesion in is 9% and skin metastasis occurs in 0.81% of all colorectal cancers. We report a patient with colonic adenocarcinoma who presented with visual disorder in her right eye and scalp pain as her initial symptoms. Contrast-enhance orbital magnetic resonance imaging with fat suppression revealed an infrabulbar mass, and skin biopsy of the posterior parietal scalp confirmed adenocarcinoma. These symptoms were diagnosed as being caused by choroidal and skin metastases of colonic adenocarcinoma. We started palliative chemotherapy with oral capecitabine(1000 mg/m2, twice a day, on days 1-14) every 3 wk, which was effective at shrinking the brain masses and improving the visual disorder. This is the first report that capecitabine is effective at reducing a choroidal and cutaneous metastatic lesion from rightsided colorectal cancer.

采用球－三盘磨损试验机在３７０℃，聚乙烯醇及磷酸三甲苯基酯气相润滑下研究了Ｓｉ３Ｎ４与Ｍ５０工具钢对磨时的磨损特性．结果表明：在气相润滑下聚乙烯醇可以有效地降低Ｓｉ３Ｎ４的磨损；在聚乙烯醇中添加少量的三甲苯基磷酸酯可以进一步降低Ｓｉ３Ｎ４的磨损．Ｘ射线光电子能谱分析发现，Ｓｉ３Ｎ４的摩擦表面形成了主要由元素碳、氧和磷组成的固体润滑膜，Ｓｉ３Ｎ４发生了氧化并生成了ＳｉＯ２和—ＳｉＮＯ等化合物，而三甲苯基磷酸酯则在摩擦过程中发生了降解．
