The present paper aims to investigate whether or not vasculogenic mimicry (VM) exists in laryngeal squamous cell carcinoma (LSCC), and to elucidate its relationship to microvessel density (MVD), galectin-3 (Gal-3) expression, and clinicopathological factors of patients with LSCC. VM, score of MVD and expression of Gal-3 protein were detected by immunohistochemistry and histochemistry in 83 specimens of LSCC tissue and 20 specimens of normal laryngeal tissue. The positive rate of VM in normal laryngeal tissues was 0%, and was 33.7% in LSCC tissues. There was a significant difference between the two groups (P<0. 01). VM or MVD was significantly related to differentiation, pTNM stages and lymph node metastasis of LSCC (P<0.05), but not to age, gender and tumor site (P>0. 05). And there was a positive correlation between every two of VM, score of MVD, and Gal-3 protein (P< 0. 05). The results suggest that expression of Gal-3 protein may be related to the initiation, angiogenesis and VM formation in LSCC; And VM, angiogenesis and Gal-3 protein may be involved in the development, invasion and metastasis of LSCC.

Objective To evaluate the valuse of endoscopic ultrasonography ( EUS ) for upper gastrointestinal submucosal lesions and the role of Photoshop in differentiating leiomyoma and stromal tumors. Methods Data of 656 patients with upper gastrointestinal submucosal lesions evaluated by EUS and receiving endoscopic submucosal dissection ( ESD ) from April 2010 to March 2015 were collected and retrospectively analyzed. The goldern standard for lesions size and origin was the intraoperative diagnosis of ESD, and that of the type of lesions ( leiomyoma, stromal tumor, ectopic pancreas, lipoma, etc.) was pathological and immunohistochemical finding. The consistency of diagnosis of the EUS was evaluated. In addition, Photoshop was used to differentiate diagnosis of leiomyoma and stromal tumors which were confirmed by pathology and immunohistochemistry. Results The consistency in diagnosing the size and lesion origins was 92?56%(560/605) and 88?43%(535/605)between EUS and ESD intraoperative result. The consistency in pathological types of EUS was 79?34%(480/605). Photoshop was used to analyze the EUS images of 177 stromal tumor and 241 leiomyoma. The gray value of stromal tumor was significantly higher than that of leiomyoma(59?97 VS 39?39, t=43?27, P<0?05).The echo of stromal tumor was higher. The standard deviation of gray value of leiomyoma were significantly lower than that of the stromal tumor ( 4?81 VS 5?42, t = 2?83, P < 0?05 ) , indicating the echo uniformity of leiomyoma was better. Conclusion EUS shows high accuracy rate for upper gastrointestinal submucosal lesions, providing more accurate basis for endoscopic therapy. EUS combined with Photoshop is helpful for differentiating stromal tumor from leiomyoma.

OBJECTIVETo investigate the expressions of WWOX and CD133 in colorectal cancer (CRC) and their relationship with the clinicopathologic characteristics of CRC.

METHODSThe expressions of WWOX and CD133 proteins were examined by immunohistochemistry in 174 specimens of CRC tissues and 80 normal colorectal mucosa tissues.

RESULTSThe positivity rates of WWOX and CD133 proteins were 41.4% and 53.4% in CRC tissues, respectively, significantly different from the rates in normal colorectal mucosa tissues (87.5% and 5.0%, respectively; P<0.05). WWOX and CD133 protein expressions were signi- ficantly correlated with the histological grades of the tumors, depth of invasion, lymph node metastasis, and Duke's stages (P<0.05). Spearman analysis showed a negative relationship between the WWOX expression and CD133 expression (P<0.05). Kaplan-Meier survival analysis showed that the overall survival time of CRC patients with a positive expression of WWOX was longer than that of patients with a negative expression of WWOX; the overall survival time of patients with a positive expression of CD133 was shorter than that of the negative patients (P<0.05). COX regression analysis identified positive expressions of WWOX and CD133 protein and Duke's stage as the independent prognostic factors of CRC.

CONCLUSIONAbnormal expressions of WWOX and CD133 might be involved in the initiation, development, invasion, and metastasis of CRC. A combined detection of WWOX and CD133 can help in predicting the progression and prognosis of CRC.

OBJECTIVE: To study the indication and the methods of hypopharyngeal and esophageal reconstruction in the surgical treatment of cervical esophageal carcinoma with laryngeal function preservation. To explore the reasons of err inhaling after gastric-pharyngeal anastomosis and its prevention and treatment. METHOD: Clinical data of nine patients who underwent surgical treatment of cervical esophageal carcinoma with laryngeal function preservation from 1998 to 2006 were analyzed retrospectively. The patients without preoperative hoarseness included two cases of pure cervical esophageal carcinoma, six cases of cervical esophageal carcinoma involved hypopharynx and one cases of cervical-thoracic esophageal poly primary malignant carcinoma. Eight patients were carried out total laryngeal function preservation and one patient was carried out partial laryngeal function preservation. The methods of hypopharyngeal and cervical esophageal reconstruction included gastric-pharyngeal anastomosis (seven patients), free forearm flap (one patient) and pectoralis major myocutaneous flap (one patient). RESULT: Good laryngeal function in four patients, moderate laryngeal function in two patients and bad laryngeal function in three patients. Everyone in seven patients underwent gastric-pharyngeal anastomosis had a very degree of gastric countercurrent, temporalitive disappearance of cough reflex and err inhaling, five of them laryngeal paralysis. The higher anastomosis gob, the heavier err inhaling. One patient with free forearm flap died of lethal haemorrhage. One patient with pectoralis major myocutaneous flap occurred anastomosis gob stricture. CONCLUSION Patients with pure cervical esophageal carcinoma and cervical esophageal carcinoma involved hypopharynx less than 1 cm from the entrance of esophagus are feasible to undergo total laryngeal function preservation operation, while elder patients with cervical esophageal carcinoma involved hypopharynx more than 1 cm from the entrance of esophagus are feasible to undergo partial laryngeal function preservation operation or no laryngeal function preservation operation instead of total laryngeal function preservation operation. Err inhaling is nearly relevant to the disorder of deglutition function of the pharynx-esophagus and err inhaling prevention function of the larynx.
