目的探讨卵巢原发性鳞状细胞癌(POSCC)的临床病理学特征及预后。方法收集2009年1月至2018年12月中国科学院大学附属肿瘤医院诊治的15例卵巢原发性鳞状细胞癌,通过免疫组织化学法检测p16、hMLH1、hMSH2、hMSH6、PMS2在POSCC中的表达,RNAscope原位杂交技术检测POSCC中18种高危型人乳头状瘤病毒(HPV)。结果15例病例中可见不同分化程度的鳞状细胞癌,包括高分化3例,中-低分化12例。肿瘤周围4例可见原位鳞状细胞癌,4例可见畸胎瘤成分,1例可见子宫内膜样癌/不典型增生成分,1例可见子宫内膜异位腺体。5例(5/15)p16表达阳性且原位杂交证实有高危型HPV感染,其余10例p16阴性病例原位杂交均未检测到高危型HPV感染。所有病例均无错配修复蛋白缺失。与无感染HPV患者相比,伴有高危型HPV感染患者的总生存时间(P=0.038)及无进展生存时间(P=0.045)较长。结论POSCC多见于绝经后女性,常为单侧发生,血清学指标CA125及鳞状细胞癌抗原(SCC)上升最常见。形态学上肿瘤呈现不同的分化程度,但目前的数据表明分化程度并不能作为患者的独立预后指标。高危型HPV感染可能与POSCC的发生相关,而且伴有高危型HPV感染的POSCC患者预后优于无感染的患者。

移动性管理(包括位置管理和切换管理)是移动通信领域的一个具有挑战性的问题,而位置管理涉及到位置更新和寻呼操作。在现行蜂窝系统中,一旦移动台越区(从一个位置区LA移动到另一个位置区LA),就需要进行位置更新。因此,移动台越区问题的研究,对蜂窝系统的设计、位置管理策略的制订与性能评价是非常重要的。该文给出越区漫游仿真算法,并对运行结果进行分析,最终得出:越区漫游有局部性。

Neural Regeneration Research 2010年第21期5卷 1673-1677页

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes （MELAS） are common types of mitochondrial encephalomyopathy. The involved muscular pathology is characterized by typical changes of mitochondrial abnormalities. Gene screening has been the gold diagnostic standard for MELAS diagnosis. This study presents three primary MELAS patients, with an age of onset from 13 to 18 years, including one patient with seizure, and two with headache and vomiting. All patients had a family history of disease, with maternal inheritance. Cerebral magnetic resonance imaging revealed abnormally high signals in T2-weighted images： temporal lobe in three cases, occipital lobe in two cases, and parietal lobe in one case. Migrating stroke-like lesions were confirmed in one patient. Muscle biopsy revealed several strongly succinate dehydrogenase-reactive vessels scattered in muscle sections of three patients, but ragged-red fibers and cytochrome c oxidase-negative/dense （COX-/＋） fibers were not observed. Mitochondrial DNA A3243G mutation was identified in all three cases. MELAS syndrome has obvious clinical heterogeneity, and muscle weakness was not prominent in some of the cases. Muscle pathological changes did not accompany ragged-red fibers or COX-/＋ fibers, but succinate dehydrogenase- reactive vessels are important for MELAS diagnosis.

As an important post-collisional magmatic product in the orogenic belt, the Himalayan leucogranites are the critical host rocks for a number of rare-metal mineralization(such as Li, Be, Cs, Rb, Nb, Ta, and Sn).However, there is still a lack of good understanding on the formation and evolution of the ***, the role of the magmatic fluids in transporting and enriching the rare elements is not *** we measure Ba isotope compositions for leucogranites from the Kampa Dome of the Himalayan belt to understand the fluid activity and behavior of fluid-mobile elements during leucogranite formation. Our results show that the δ138/134 Ba of leucogranites range from -1.32‰ to +0.12‰, much lower than the literature values for S-type granites and various sedimentary materials, suggesting that the Ba isotope compositions of the leucogranites does not reflect the sedimentary source signatures. Instead, their low δ138/134 Ba is accompanied by non-charge-and-radius-controlled(CHARAC) twin-element(such as Nb/Ta) behaviors, clearly showing the involvement of magmatic fluids during magma *** studies suggest that the low δ138/134 Ba of the magmatic fluids most likely results from exsolution from a large deep magma reservoir. Such fluids not only modified Ba isotope compositions of the leucogranites, but also transported many fluid-mobile metal elements which may help form the rare metal ore deposits. Therefore, Ba isotope data provide new insights into formation and evolution of magmatic fluids and exploration of the rare-metal mineralization.
