ObjectiveTo investigate the characteristics,treatment and prognosis of solid pseudopapillary tumor of the pancreas(SPTP)in the minor. MethodsCombining minor SPTP cases in literatures and 4 cases, analyzed the clinical and pathological features, and the relationship with sex hormone receptors, the growth and development,treatment and prognosis.ResultsThe clinical manifestations of SPTP in minor were same as adults, but the minors showed significant growth retardation which can be reversed after the tumor surgical removal, like 4 patients all showed secondary sex characteristics of retardation in the group. The protocol of surgical treatment was to ensure complete removal of the tumor and keep the healthy organs as much as possible which reduced the impact to the postoperative growth and development.The premise of operation therapy in the 4 cases was minimization of operation trauma. Minor SPTP prognosis had not been determined. ConclusionThe diagnosis and treatment of minor SPTP should be fully taken into account the characteristics of the minor to ensure that patients can continue long-term growth and development and the quality of life.

To study the relationship between serum Pre-S1 antigen and HBV DNA, serum Pre-S1 antigen and HBV DNA marker in 229 patients positive for HbsAg were detected by using ELISA method and compared. It was found that both Pre-S1 antigen and HbeAg were correlated with HBV DNA with the coefficient being 0. 9812 and could be used to reflect the existence or reproduction of HBV DNA well. Although there was statistical correlation between them, their clinical implication was not completely the same. Therefore, a conclusion was drawn that combined detection of Pre-S1 antigen, HBV and HBV DNA in the patients with different kinds of HBV infection was helpful to clinical diagnosis, therapeutic effect evaluation and prognosis judgement.

Tissue engineering has evolved as a dynamic research field that encompasses multidisciplinary approaches involving cytology,material science,bioreactor engineering,and medicine.The overarching goal is to construct human tissue and organs in the laboratory for tissue regeneration or replacement.It offers a potential solution to the donor shortage in organ transplantation and to the difficulties in regenerative medicine.The basic components for tissue engineering include seed cell selection,bio-scaffold construction,and ex vivo tissue formation via a bioreactor. Over the past decade,tremendous progress has been made in bioengineering cartilage,trachea,urinary bladder,heart valve and endocrine tissues. However,there remain significant challenges in creating complex and human-sized tissues and organs for clinical use.In this article,we review the basic components and strategies for bioengineering organs. We attempt to provide an overview of current progress and challenges in developing organ-level tissue engineering and in the successful translation of bioengineered tissue and organ products into daily clinical practice.

Objective To summarize the clinical experience of laparoscopic repair of acute perforation for gastroduodenal ulcer. Methods From June 2003 to December 2007, 13 patients underwent laparoscopic repair of pedorated peptic ulcers. Results Five patients were suffered from pedorated duodenal bulbar ulcer, one patient was suffered from pyloric canal ulcer, and seven patients were suffered from perforated gashie antrum ulcer. The diameter of the perforation was 0. 3-0. 7cm, peritoneal fluid 600-1200ml, the operafive time was 80-180min, only one was shifted to open surgery diagnosed gastric cancer by pathology examination, another twelve laparoscopic operations were successful. Postoperative recovery was smooth, ten surgical incisions were class A healing and two were class B healing, the length of hospitalization were 7-10 days after surgery. With one year followed-up, all deers had healed well by Gastroscopy, we hadn't found reperforation, abdominal infection, ankylenteron, ileac passion ect. operative complications. Conclusions Laparoscopic repair of acute perforated gastroduodenal ulcer is as safe and effective as the open repair. We must do intraoperative rapid pathologic examination, if it was malignant disease we shifted to open surgery.
