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 ...

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）

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 295-302, March 2025.ABSTRACT Objective Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders ...

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 ...

Zhongguo shiyan zhenduanxue, 2014 目的研究人组织激肽释放酶基因6（KLK6）mRNA和蛋白在卵巢肿瘤组织中的表达水平,探讨其在卵巢恶性肿瘤中的作用机制。方法应用RT-PCR和免疫组化SP法分别检测在正常的卵巢组织、卵巢的良性肿瘤、卵巢的交界性肿瘤及卵巢的恶性肿瘤组织中KLK6的mRNA表达及蛋白的表达,探讨该基因的表达与卵巢恶性肿瘤患者的临床病理特征关系。结果本研究显示,在卵巢癌组织中,KLK6mRNA的表达水平与正常卵巢组织相比,显著增高;卵巢癌组织中KLK6蛋白的阳性表达率为69.4%,与正常卵巢组织（13.3%）、良性卵巢肿瘤 ...
