Pleuropulmonary blastoma (PPB) is a kind of rare malignancy which often occurs in children and is related to dysplasia. It always involves in pleura and lung. PPB is misdiagnosed easily because of its special pathophysiological characters and complex biological behavior. Early detection and correct treatment are very important for thoracic surgeon to cure PPB. This paper reviews the advance of pathophysiological characters, molecular genetic characters, clinical manifestation, clinical diagnosis and differential diagnosis, and treatment and prognosis of PPB.
In order to protect the integrity and function of the digestive system, duodenum-preserving total pancreatic head resection is becoming the surgical method which was chosen by more and more doctors for benign lesions or low-grade malignant tumors of the pancreatic head. With the development of minimally invasive concepts and techniques, laparoscopic technology has brought unique advantages to this surgery. In this paper, a series of problems such as the development process and indications of laparoscopic duodenum-preserving total pancreatic head resection were discussed, and the core techniques of surgery and how to reduce the occurrence of complications were emphasized. The aim is to improve the therapeutic effect and quality of life of patients through reasonable surgical methods and treatment strategies.
Objective To observe the action and correlation of p16 and estrogen receptor (ER) in papillary thyroid cancer (PTC).Methods Using immunohistochemical method, the p16 and ER in 50 cases of PTC were detected. Results The expression of p16 and ER was associated with the cellular differentiation, the lymphatic metastasis and prognosis in PTC. Conclusion It is helpful to detect the p16 protein and ER for analyzing the cellular differentiation degree and prognosis in PTC.
Objective To assess the short-term effect of the mini-invasive surgical method by Achillon in repair of acute achilles tendon rupture. Methods Between December 2009 and February 2010, 11 patients (11 feet) with acute achilles tendon ruptures were treated, including 8 males (8 feet) and 3 females (3 feet) with an average age of 35.4 years (range, 23-58 years). There were 9 cases of jump injury, 1 case of glass cut injury, and 1 case of fall injury. The results of Thompson testwere positive in 11 cases (11 feet). According to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfootscoring system, the score was 53.19 ± 6.31. MRI indicated that the gap of the acute achilles tendon rupture was 1-5 cm (3.8 cm on average). The interval between injury and operation was 2-7 days (3.6 days on average). An approximately longitudinal 3- 4 cm incision was performed and the ruptured achilles tendon was repaired by use of Achillon. Early rehabil itation was carried out. Results The operation time was 27-58 minutes (38 minutes on average). The hospital ization time were 2-3 days (2.5 days on average). Superficial wound infections occurred in 2 cases, and wound healed after dressing change; orther incision healed by first intention. All the patients were followed up 5-8 months with an average of 6.7 months. No wound problems, sural nerve injuries, or re-ruptures occurred in the other cases. After a 3-month follow-up, all patients were able to return to normal walking. The AOFAS ankle-hindfoot score was 94.32 ± 4.23, showing significant difference when compared with that before operation (P lt; 0.05). Conclusion The technique with Achillon offers patients a safe procedure for repair of acute achilles tendon ruptures and early active rehabil itation can be carried out.
