, 2004 在鹿特丹ESHRE/ ASRM 主办的多囊卵巢综合征( PCOS) 协调会上, 专家们同意, 如果妇女有下列三项中的两项即可诊断PCOS: ( 1) 排卵少或不排卵; ( 2) 有高雄激素血症的临床和生化特征; ( 3) 超声检查有多囊性卵巢。PCOS 确切的病理生理尚不清楚。常见有促性腺激素紊乱导致不排卵和高雄激素血症。近年来, 有越来越多的证据显示胰岛素抵抗可能在其中起重要的作用。PCOS 可能表现有不同的症状, 包括月经不规律、闭经、多毛或其他高雄激素血症的多种症状和不育。对PCOS ...

Recent progresses of study on oogenesis of teleost(硬骨鱼类卵子发生研究及其应用前景)
Zhejiang Daxue xuebao. Lixue ban, 2003 硬骨鱼类的发育有卵生和卵胎生两种形式,其卵子发生的过程相似,目前人为地将卵原细胞到卵母细胞分为6个连续时相.卵原细胞期的卵巢体积小,卵原细胞均一,单层滤泡期卵巢体积增大,初级卵母细胞为主,卵黄和滤泡细胞出现,细胞代谢加强,卵黄泡期卵巢亦增大,卵膜开始形成,卵黄沉积,出现卵黄粒和脂肪滴,卵黄充满期卵巢继续增大,卵母细胞个体急剧增大,卵黄球和皮质泡形成,个别出现油滴,卵膜增厚,成熟期卵巢和卵子达到最大,各种不同鱼类的卵膜形态不一,衰退期卵巢退回到单层滤泡期,多次产卵类型退回到卵黄充满期,继续保持产卵能力 ...

Integrative Conservation, Volume 4, Issue 4, Page 523-526, December 2025.Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...

Zhongguo shiyan zhenduanxue, 2011 目的探讨上皮性卵巢癌组织中组蛋白去乙酰化酶1（HDAC1）的表达及临床意义。方法采用免疫组化SP法,测定40例上皮性卵巢癌组织2、0例交界性卵巢肿瘤,20例卵巢良性肿瘤以及10例正常卵巢组织中HDAC1的表达。结果 HDAC1在在卵巢组织中的阳性表达H-score评分均随组织异型程度的增加而逐渐增高,即正常卵巢组织（1.300±0.948 68）和卵巢良性肿瘤（1.750±0.786 40）

CA125与HE4联合检测及不同CA125阳性区间在卵巢肿瘤鉴别诊断中的意义
Zhongguo shiyan zhenduanxue, 2015 卵巢肿瘤是女性常见的妇科肿瘤,其中卵巢上皮性肿瘤最常见,占原发性卵巢肿瘤的50%-70%,包括卵巢良性、交界性及恶性肿瘤。卵巢深居盆腔内,且卵巢肿瘤临床症状多不典型,如何在术前较准确地判断其性质,确定治疗方案,仍是临床医生比较棘手的问题。卵巢交界性肿瘤是一种低度潜在恶性的卵巢肿瘤,占卵巢上皮性肿瘤的10%-15%[1]。卵巢恶性肿瘤的发病率占女性生殖道恶性肿瘤的第三位,且有逐年增高趋势 ...
