Objective To improve the diagnosis and therapy level of the uterine intravenous eiomyomatosis, we reported one case involving the right heart and reviewed the relative literatures.Methods and results The patient is 38 years old, she was admitted to hospital with fever, abdominal pain and chest tightness for one week in July 2010. She had a total hysterectomy owing to hysteromyoma in 2003. In July 2010, because she wanted a baby with the method of surrogate pregnancy, so she was injected medicine to stimulate follicle growth in the USA. The medicine was Li ShenBao injection, the total of 12d daily 3 branch (dose not stated). Afterward she couldn't stand fever, abdominal distension and chest tightness, she returned to China for treatment. After she was hospitalized, for diagnosis she got many image examination done, such as B-scan, CT, MRI and PET/CT. Result All image examination found that a massive solid and cystic tumor in the abdominal and pelvic cavity, left kidney hydrocele, ascites, and tumor embolus in the right atrium, inferior caval vein, left renal vein, also bilateral iliac vein. The thoracic-abdominal surgery was carried out, massive tumor was removed, also the tumor embolus in the right atrium and inferior caval vein. The pathological diagnosis was uterine intravenous leiomyomatosis. Conclusion Uterine intravenous leiomyomatosis is a rare disease, involving to heart case is seldomness. In recent years, the case increasing could be related with the usage count of sex hormone in Assisted Reproductive Technology. The imaging examination can give a confident diagnosis, and the final diagnosis depend on pathology. For treatment, surgery is the first choice, and must be thorough to prevent recurrence.

Objective: To observe the ultrasound characteristics of galactostasis at various physiological stages, so as to improve the diagnosis of galactostasis. Methods: The ultrasound data of 56 patients with galactostasis were retrospectively analyzed and the ultrasound characteristics were summarized. The ultrasonic manifestations of different physiological stages were compared. Results: During the lactation period,there were extensive mammary duct ectasias and floating weak signals were found in the mammary duct during pure galactostasis; large non-responsive fluid areas exhibited formations of honeycomb-like multilocular fibrous septa; and these cavities ruptured with abscess when secondary infection occurred. During the later lactation period,the dilated galactophores became hypoechoic or anechoic,which,together with the dot-like echoes of residual breast milk or macular strong echoes, formed mixed signals of retention cysts. After menopause, the galactophores atrophy occurred; the accumulation of galactostasis desiccated into patches or powder, which caused thick hyperechoic dots or multiple hyperechoic streaks in the galactophores or parenchyma. Conclusion: Ultrasonic images of galactostasis vary with the physiological and pathological changes of the mammary glands, and are related to the duration of galactostasis, absorption, concentration and desiccation of lactation.

ObjectiveTo investigate the clinical features,early diagnosis and therapeutic methods of primary tumor of the duodenum.MethodsThe clinical data of 130 patients of primary tumor of the duodenum who were hospitalized in Peaking University Third Hospital from 1974 to 2010 were summarized.There were 30 cases of benign tumors and 100 cases of malignancy. ResultsMore than 90％ of primary tumors of the duodenum were located at the duodenal bulb and descendent part.59％ of malignant tumors were located in the area of duodenal papilla. The mean diameter of benign tumors was less than 2 cm compared with more than 3 cm in malignancies. Upper abdominal pain,jaundice,black stool,intestinal obstruction and abdominal mass were among the most common clinical manifestations. Jaudice was most common in papilla tumors,and intestinal obstruction and palpable abdominal mass often indicate advanced stage.Duodenofiberscopy combined with air barium double contrast radiography increase the diagnosis rate.Among the 30 benign cases,11 cases underwent simple tumor resection,14 cases received endoscopic tumor resection and 3 cases underwent pancreaticoduodenectomy.Resection rate and the 5-year survival rate was 100％. Of the 100 malignant cases,56 cases underwent standard pancreaticoduodenectomy,3 cases received pylorus preserving pancreaticoduodenectomy,9 cases underwent simple tumor resection and 12 cases received segmental duodenectomy.Resection rate was 84％.The 5-year survival rate was 46％ in 59 cases receiving Whipple's procedure.ConclusionsPrimary tumor of the duodenum lacks specific clinical features. Simple tumor resection and segmental duodenectomy can be done for benign cases, while pancreaticoduodenectomy is the therapy of choice for malignant cases.

Spermatogenesis is a process consisting of spermatogonial proliferation, spermatocytic meiosis, and spermiogenesis, and is also considered to be a process in which heterochromatins gradually aggregate and finally reach a highly condensed formation in the sperm head. Recent studies show that epigenetic regulation plays a key role in spermatogenesis. This review discusses the mechanisms of epigenetic regulation in spermatogenesis in three aspects, DNA methylation, histone modification, and noncoding RNAs. These factors are essential for spermatogenesis, fertilization, and embryogenesis by mutual regulation as well as by gene expression regulation, transposon activation, sex chromosome inactivation, and genome imprinting.
