By comparison and combination of two strategies, extending π-conjugation and tuning Intramolecular Charge Transfer (ICT) effect, new long-wavelength BODIPY dyes have been efficiently synthesized. The new chromophores exhibit good optical properties: high fluorescence quantum yields, exceptionally large molar extinction coefficients, narrow red-emission(More)
Bulky 4-tritylphenylethynyl substituted boradiazaindacene with pure red emission, relatively large Stokes shift, high fluorescence quantum yield, and low self-quenching was efficiently synthesized and qualified as a potential EL dopant.
A cassette molecule, featuring direct integration of two donor BODIPY units to one acceptor BODIPY unit, was conveniently developed as the first highly "through-bond energy transfer" (TBET) laser dye. This multicolor absorbing dye exhibited highly efficient and photostable laser action under drastic pumping conditions.
OBJECTIVE To explore the clinicopathological characteristics and prognosis of colon cancer patients with extremely elevated serum carcinoembryonic antigen(CEA) level before operation(>50 μg/L). METHODS Clinicopathological and follow-up data of 1250 patients with colonic adenocarcinoma undergoing primary tumor resection between January 2001 and December(More)
OBJECTIVE To examine the association of preoperative carcinoembryonic antigen (CEA) level with the efficacy of neoadjuvant radiochemotherapy and postoperative metastasis and relapse in patients with rectal cancer. METHODS Between January 2011 and January 2014, 325 patients with local advanced rectal cancer underwent preoperative radiochemotherapy and(More)
OBJECTIVE To compare the perioperative safety and efficacy between hand-assisted laparoscopic surgery(HALS) and conventional open sigmoidectomy. METHODS A total of 291 patients with sigmoid colon cancer who underwent surgery in our hospital from January 2010 to June 2013 were seperated into (HALS) group (n=200) and conventional open surgery (COS) group(More)
Human labeled corpus is indispensable for the training of supervised word segmenters. However, it is time-consuming and labor-intensive to label corpus manually. During the process of typing Chinese text by Pingyin, people usually need to type "space" or numeric keys to choose the words due to homo-phones, which can be viewed as a cue for segmentation. We(More)
