PCOS患者卵泡液微环境中的亚急性炎症反应

目的:回顾性分析多囊卵巢综合征(PCOS)患者及对照者卵泡液微环境中局部脂代谢紊乱及炎症反应状态及其形成机制。方法:比较2组患者外周血清脂代谢指标、性激素、炎症细胞及炎症介质水平差异;测定卵泡液中炎症介质及载脂蛋白含量;分析卵巢颗粒细胞中炎症介质及载脂蛋白基因表达。结果:PCOS患者具备典型肥胖、高脂血症及高雄激素血症,外周血中炎症细胞及各类炎症介质水平显著增加;卵泡液中同样具有显著增加的炎症细胞因子浸润,颗粒细胞内炎症介质及载脂蛋白基因表达增加。结论:PCOS组患者卵泡液内所含高水平载脂蛋白表明卵泡液内可能存在高脂蛋白状态。循环中的高脂血症及亚急性炎症各类因子可能通过血清-卵泡液屏障主动渗透。颗粒细胞通过主动摄取(例如载脂蛋白A)抑或自主合成(如炎症因子IL-1、IL-6及TNF-α等)等多种方式进行卵泡液局部微环境的稳态调节。卵子发育生理性卵泡液微环境的脂质代谢紊乱、炎症细胞浸润、高雄激素血症等均可能影响到卵母细胞和胚胎的正常发育。     

Absent right atrioventricular connexion with the left atrium connected to the morphologically right ventricle, a right-sided rudimentary left ventricle, and right juxtaposition of the atrial appendages: documentation by angiography and cross-sectional echocardiography

In this report, a 12-hr-old male infant was demonstrated to have the absent connexion variant of right atrioventricular valve atresia with the left atrium connected to the morphologically right ventricle with a right-sided rudimentary left ventricle. The aorta arose from the right ventricle and there was pulmonary atresia, the pulmonary circulation being duct-dependent. In addition there was right juxtaposition of the atrial appendages. The definitive cross-sectional echocardiographic and angiographic findings are presented.     

A new prenatal sonographic sign of epidermolysis bullosa

We report on the prenatal sonographic appearance of epidermolysis bullosa (EB). The third viable pregnancy of a consanguineous couple was found at 23 weeks to have dysplastic external ears and nose. The neonate was born at 33 weeks and was found to have junctional EB with pyloric atresia. On reviewing the 23‐week ultrasound images, skin denudation was evident. This is a report of visualization of skin denudation in EB. When EB is suspected prenatally, special attention should be given to the visualization of skin surfaces.     

Unilateral pulmonary agenesis associated with oesophageal atresia and tracheoesophageal fistula: A case report with prenatal diagnosis

We describe herein a case of unilateral pulmonary agenesis (PA) with oesophageal atresia (EA)/tracheoesophageal fistula (TEF) that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4^th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.     

不同类型阴道闭锁的超声诊断

目的:探讨不同类型阴道闭锁的声像图特征,提高超声下阴道闭锁的诊断及分型的准确性. 方法:回顾性选取四类阴道闭锁病例共19例,对其声像图特点进行分析. 结果:超声显示阴道积液10例,宫颈积液16例,宫腔积液18例,其中1例另伴有盆腔内巨大囊性包块. 结论:超声在阴道闭锁的分型、诊断和鉴别诊断中起重要作用.
