BACKGROUND Meta-analysis of randomized trials has shown that postoperative radiotherapy (PORT) had a detrimental effect on overall survival (OS) in patients with resected N1 non-small cell lung cancer (NSCLC). Conversely, the locoregional recurrence (LR) rate is reported to be high without adjuvant PORT in these patients. We have evaluated the pattern of(More)
PURPOSE We intended to identify risk factors that affect brain metastases (BM) in patients with locally advanced non-small cell lung cancer (LA-NSCLC) receiving definitive radiation therapy, which may guide the choice of selective prevention strategies. METHODS AND MATERIALS The characteristics of 346 patients with stage III NSCLC treated with thoracic(More)
BACKGROUND The role of adjuvant radiotherapy (RT) for patients with stage III thymoma after complete resection is not definite. Some authors have advocated postoperative RT after complete tumor resection, but some others suggested observation. In this study, we retrospectively evaluated the effect of postoperative RT on survival as well as tumor control in(More)
Artificial Fish Swarm is a kind of swarm intelligence algorithm, which focuses on the behavior of individual fishes and information interactions among them during foraging and preying on something in real environment. A novel Artificial Fish Swarm Optimization Algorithm Aided by Ocean Current Power (abbreviation for AFSAOCP) is proposed, which assumes the(More)
OBJECTIVES This study aimed to determine the efficacy and feasibility of preoperative radiotherapy with or without chemotherapy (XRT) followed by surgery of locally advanced pyriform sinus carcinoma. MATERIALS AND METHODS We performed a retrospective study of 482 patients with T3 and T4 pyriform sinus carcinoma treated with curative intent between 1979(More)
Satellite attitude accuracy is an important factor affecting the geometric processing accuracy of high-resolution optical satellite imagery. To address the problem whereby the accuracy of the Yaogan-24 remote sensing satellite's on-board attitude data processing is not high enough and thus cannot meet its image geometry processing requirements, we developed(More)
OBJECTIVE Through analysis of variation and function of five endogenous hormones (IAA, GA3, ABA, ZR and JA) in the formation of microtubers of Pinellia ternata in vitro to explore the physiological and biochemical mechanism of tubers' development. METHOD The endogenous hormones of microtubers were isolated in different stages of tubers expansion when the(More)
The design of optoelectronic integrated transmitter and receiver for plastic optical fiber(POF) communication applications realized in 0.5μm BCD (Biplor, CMOS and DMOS) process is presented in the report. The hybrid on-chip integrated transmitter includes a driver with temperature compensation of modulation current and a bonded 650nm resonant cavity(More)
INTRODUCTION The current pathologic nodal classification (pN) based on anatomic location of involved lymph nodes (LNs) is unsatisfactory in distinguishing heterogeneous pN1 or pN2 non-small cell lung cancer (NSCLC). For the first time we comprehensively compared the prognostic significance of the number of positive LNs (nN), the ratio of the number of(More)
