作者： hong-sheng Liu Ying-zhi Qin Shan-qing Li Li Li Yu-shang cui zhi-yong Zhang Department of Thoracic Surgery Peking Union Medical College Hospital ChineseAcademy of Medical Sciences ＆ Peking Union Medical College Beijing 100730 China

Objective To evaluate the use of titanium mesh reconstruction after sternal tumor resection. Methods From January 2007 to January 2011, 14 patients with sternal tumors were admitted into Peking Union Medical Hospital. The clinical characteristics, surgical resection, and technique of reconstruction were reviewed. Results Of the 14 patients, 3 had a metastatic sternal tumor, the primary sites of which were as follows: hepatic carcinoma in one case (metastasis 19 years after operation), breast carcinoma in another case (metastasis 5 years after operation), and renal carcinoma in the other case (found simultaneously). Two patients showed local involvement of the sternum: 1 had thymic carcinoma, and the other had myofibrosarcoma. The remaining 9 patients had primary tumors: 4 were osteochondroma, 3 chondrosarcoma, 1 eosinophilic granuloma, 1 non-Hodgekin's lymphoma. En bloc resection of the sternal tumor was performed in all the 14 patients. The defect was repaired with the titanium mesh adjusted to the shape of the defect and fixed with the stainless steel wire. Eleven patients were followed up for a period from 2 months to 4 years, during which no translocation or broken of the titanium mesh was observed. Conclusions Radical en bloc excision remains the treatment of choice for sternal tumors. Sternum defect reconstruction using titanium mesh as a rigid replacement proves appropriate and effective.

Detection of Cholangiocarcinoma with Fourier Transform Infrared Spectroscopy and Radial Basis Function Neural Network Classification

引用

Chemical Research in Chinese Universities 2016年第4期32卷 561-564页

作者： WU Min cui Long LING Xiaofeng XU zhi Department of General Surgery Peking University Third Hospital Beijing 100191 P. R. China

The aim of this study was to explore the possibility of applying Fourier transform infrared（FTIR） spec- troscopy as a medical diagnostic toot based on a neural network classifier for detecting and classifying cholangiocar- cinoma. A total of 51 cases of bile duct tissues were obtained and later characterized by FTIR spectroscopy prior to pathological diagnosis. The criteria for classification included 30 parameters for each FTIR spectra, including peak position（P）, intensity（/） and full width at half-maximum（FWHM）, were measured, calculated and subsequently com- pared against the normal and cancer groups. The FTIR spectra were classified by the radial basis function（RBF） net- work model. For establishing the RBF, 23 cases were used to train the RBF classifier, and 28 cases were applied to validate the model. Using the RFB model, nine parameters were observed to be pronouncedly different between can- cerous and normal tissue, including I1640, I1550, 11460,/1400, I1250, I1120,/10g0, Ii040 and P1040. In the RBF training classi- fication, the accuracy, sensitivity, and specificity of diagnosis were 82.6%, 80.0%, and 84.6%, respectively. While validating the classification, the accuracy, sensitivity, and specificity of diagnosis were 78.6%, 75.0%, and 81.2%, respectively. The results suggest that FTIR spectroscopy combined with neural network classifier could be applied as a medical diagnostic tool in cholangiocarcinoma diagnosis.

Gasless laparoscopy for benign gynecological diseases using an abdominal wall-lifting system

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2009年第11期10卷 805-812页

作者： Yue WANG Heng cui Yan ZHAO zhi-qi WANG Department of Obstetrics and Gynecology Peking University People's Hospital Beijing 100044 China

Objectives: The use of gasless laparoscopy with an abdominal wall-lifting device for benign gynecological diseases was compared to conventional laparoscopy with CO2 pneumoperitoneum. Methods: From February 2007 to July 2007,76 women with uterine and/or adnexal benign diseases and candidates for laparoscopic surgery were recruited in this study. Thirty-two women underwent gasless laparoscopic surgery and 44 women underwent pneumoperitoneum laparoscopic surgery. Results: Diverse pathologies,including adnexal cyst,uterine myoma and ectopic pregnancy,were treated successfully with gasless laparoscopic surgery. Compared with the patients in the pneumoperitoneum group,the similar hospital stay (P=0.353) and intraoperative blood loss (P=0.157) were observed. However,the mean operative time in the gasless group was significantly longer than that in the pneumoperitoneum group (P=0.003). No severe intraoperative or postoperative complications were found in either group,except for one case of laparotomic conversion in the pneumoperitoneum group due to dense pelvic adhesions. The total hospital charges were significantly less in the gasless group than in the pneumoperitoneum group (P=0.001). In 38 cases of ovarian cyst resection,the mean operative time in the gasless group remained longer than that in the pneumoperitoneum group (P=0.017). The total hospital charges were also significantly less in the gasless group than in the pneumoperitoneum group (P<0.001). Conclusion: Our preliminary results demonstrated that the laparoscopic procedure using the gasless technique was a safe,effective method to treat benign gynecological diseases. Moreover,it was easy to master. As a minimally invasive treatment,gasless laparoscopic surgery provides a good choice to patients in the undeveloped regions in China without increasing the patients’ and the government’s burden significantly.
