The different operation methods should be selected according to the different sides and sizes of the tumor;the parotid gland pleomophic adenoma in superficial lobe with clear limit and small size shouid be treated by local regional excision to reduce facial deformity and various kinds of complications,but those with too big size and vague limit should be done by traditional superficial lobe parotidectomy.

应根据肿瘤的部位及大小选择不同的术式，对界限清楚、体积较小的腮腺浅叶多形性腺瘤应尽量采用腮腺区域性切除术，预防面部凹陷畸形，减少并发症；对过大或边界不清的肿瘤仍宜采用传统腮腺浅叶切除术，以减少复发。

Polycystic ovary syndrome , one of the most common endocrine diseases affecting women of reproductive age, plays an important role in anovulatory infertility, with a prevalence of up to 5%~21%; The main clinical manifestations include irregular menstruation (amenorrhea or infrequent menstruation or dysfunctional uterine bleeding), infertility, hirsutism, obesity and acanthosis nigricans. Elevated serum LH levels and hyperandrogenism, insulin resistance with compensatory hyperinsulinemia are its endocrinological features. Polycystic ovary morphology is also a common feature in PCOS. With the advance researches, PCOS displays its complexity and essential trend.

多囊卵巢综合征(polycystic ovary syndrome，简称PCOS)是育龄期妇女最常见的内分泌紊乱性疾病之一，在不排卵性不孕中占主要地位，发病率约5%～21%；主要表现为月经异常、不孕、多毛、肥胖及黑棘皮征，以高雄激素血症、促性腺激素异常、高胰岛素血症及胰岛素抵抗等内分泌学特征，以双侧卵巢增大呈囊性改变并间质增生为病理形态学基础的多系统疾病。

On CT or MRI, many malignant tumors, such as acinic cell carcinomas or low-grade mucoepidermoid carcinomas, appear indistinguishable from benign tumors, such as pleomorphic adenomas.

结果发现，在正常鼻咽粘膜表面及隐窝的假复层纤毛柱状上皮细胞胞膜、部分小涎腺的导管上皮和个别浆液性腺泡上皮细胞的胞膜和胞浆Fas阳性表达；鳞状化生上皮的表层细胞胞膜有Fas表达，但基底细胞未见Fas表达；浸润的淋巴细胞也不表达Fas.45.9%（17/37）的鼻咽非角化性癌Fas阳性，但只有不足10%的癌细胞胞膜微弱表达Fas。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

The sex and gonad development in cultured Acipenser baerii was scanned by ultrasonic scanning. The results of sex and development stages of scanned A. baerii were identified by Minimally Invasive Surgical technique and histological examination.
