Objective To study the quantitative expression and the correlation of the NF-κB p65,COX-2 and MMP-9 Drotein in the hypopharyngeal carcinoma tissue.Methods FCM method was performed to detect the quantitative expression of the NF-κB p65,COX-2 and MMP-9 protein in 48 cases of hypopharyngeal carcinoma fresh sample and 48 cases of para-carcinoma tissue.Fluorescence Index wasdeftned as the quantitative expression index of the three proteins.Results The quantitative expression of the NF-κB p65,COX-2 and MMP-9 in hypopharyngeal carcinoma tissues(1.16,1.32 and 1.26) was remarkably higher than in para-carcinoma(1.03,1.04 and 1.04).The quantitative expression of three proteins in metastasis group was obviously higher than in non-metastasis group.The expression of NF-κB p65 and COX-2 protein in hypopharvngeal carcinoma tissues was positively related (P＜0.05). Conclusion The high expression of NF-κB p65 and COX-2 is closely related in hypopharyngeal carcinoma tissues.NF-κB p65 might improve the expression of COX-2.

Objective To investigate the capability of 99 Tcm?tricine?EDDA/HYNIC?SFSIIHTPILPL ( SP94) as a specific probe for HCC imaging. Methods HYNIC?SP94 peptide was prepared by solid phase synthesis, followed by 99 Tcm labeling with tricine?EDDA as the coligand. After determination of radiochemical purity and stability, cell binding study was carried out by incubating Huh?7 cells with 99 Tcm?tricine?EDDA/HYNIC?SP94 at different specific activities (2.5, 4.0 and 30.0 GBq/μmol). The biodistribution studies and microSPECT/CT imaging were performed in Huh?7 tumor?bearing mice ( study group) and Hela tumor?bear?ing mice ( control group ) . Statistical analysis was by two?sample t test. Results 99 Tcm?tricine?EDDA/HYNIC?SP94 was synthesized with over 95% of labeling yield, which remained stable in saline and FBS up to 12 h. With increasing concentrations of 99 Tcm?tricine?EDDA/HYNIC?SP94, Huh?7 cell binding increased but became gradually saturated. In biodistribution studies, (1.02±0.26) %ID/g of tracer was accumulated in Huh?7 tumors at 0.5 h after injection of 99 Tcm?tricine?EDDA/HYNIC?SP94, higher than that in the HYNIC?SP94 blocking group ((0.34±0.09) %ID/g;t=3.537, P<0.05). Compared to Hela tumors, Huh?7 tumors were clearly visualized by microSPECT/CT, with which better imaging quality could be achieved with higher specific radioactivity. Conclusion 99 Tcm?tricine?EDDA/HYNIC?SP94 could achieve a high labeling effi?ciency and good in vitro stability as a potential diagnostic tracer specifically targeted for HCC.

Objective To investigate time distribution of pressure of footplate in each stage and vertical anti-force from ground of patients with knee osteoarthritis (KOA).Methods 40 KOA patients, 10 aged people, and 10 common saplings were selected to test time distribution of pressure of footplate in each stage and vertical anti-force from ground in period of monopodia support.Results To unilateral KOA patient, there was not obvious difference to be observed in initial contact phase and forefoot push off phase ( P>0.05), but there was a significant difference in forefoot contact phase and foot flat phase between health side and sick side ( P<0.001), and there was obvious difference decreased buffer time and buffer force coefficient between them ( P<0.01).Conclusion To KOA patients, the time decreases in weight-bearing phase and absorption shocks, and amortization coefficient also decreases. These indexes can be used as the walking index of functional assessment and the objective evidence of curative effect.

OBJECTIVE: To study the correlation between the stromal cell-derived factor (SDF-1) and the receptor fusin (CXCR4) in carcinoma of larynx, and investigate some mechanisms of SDF-1/CXCR4 during the development, invasion and lymph node metastasis of laryngocarcinoma. METHOD: Detecting the expression of SDF-1 and CXCR4 by immunohistochemical method (SP) in laryngocarcinoma, paraneoplastic tissues, normal laryngeal mucosa and cervical lymph node. Using Kruskal-Wallis H test, chi2 test, Spearman rank correlation analysis and so on to do statistical analysis. RESULT: The positive expression rate of SDF-1 and CXCR4 in laryngocarcinoma was obviously higher than in paraneoplastic tissues and normal laryngeal mucosa tissues (P < 0.01). And the expression of two proteins was correlated with lymph node metastasis (P < 0.01), clinical stage (P < 0.01) and pathological grading of tumor (P < 0.05). The positive expression rate of SDF-1 and CXCR4 protein in metastasis lymph node tissue was higher than that in non metastasis lymph node tissue (P < 0.01). The expression of SDF-1 is correlated positively with the expression of CXCR4 in laryngocarcinoma. CONCLUSION SDF-1 and CXCR4 protein are highly expressed in laryngocarcinoma and in metastasis lymph node tissue. And they are correlated with lymph node metastasis, clinical stage and pathological grading of the tumor. According to the results, the two proteins may relate to infiltration and metastasis of laryngeal squamous cell carcinoma and play a role of synergistic action in the development and invasion of carcinoma of larynx.

OBJECTIVETo evaluate the feasibility of right neck anastomosis in thoracoscopic and laparoscopic esophagectomy.

METHODSThis study used a retrospective cohort study method. Clinical data of 169 patients with stage I-III esophageal squamous cell carcinoma undergoing neck anastomosis in thoracoscopic and laparoscopic esophagectomy at the Department 5 of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from November 2013 to October 2016 were retrospectively analyzed. Eighty-two cases underwent right neck anastomosis (right neck anastomosis group) and 87 cases underwent left neck anastomosis(left neck anastomosis group). Both groups underwent routine thoracoscopic and laparoscopic radical resection of esophageal cancer. The entry of right and left neck anastomosis group was at the anterior edge of the right and left sternocleidomastoid muscle respectively. Anastomosis of the esophagogastric junction was performed and the drainage tube was placed in the neck incision. The operation time, intraoperative blood loss, lymph node dissection and morbidity of postoperative complications were compared between the two groups.

RESULTSThere were 101 males and 68 females among 169 patients with esophageal cancer. There were no significant differences in age, gender, tumor location, clinical stage between two groups(all P>0.05). The total operation time of left and right neck anastomosis groups was (278.3±39.4) minutes and (287.8±39.4) minutes, respectively (t=1.563, P=0.120). The intraoperative blood loss was (134.9±71.5) ml and(147.9±85.5) ml, respectively (t=1.074, P=0.284). The number of lymph node dissections was (17.45±5.68) and (16.47±4.98), respectively (t=1.190, P=0.236). Seventeen cases(20.7%) in the right neck anastomosis group developed postoperative complications, while 31 cases (35.6%) in the left neck anastomosis group developed postoperative complications (χ²=4.609,P=0.032). Compared with left neck anastomosis group, right neck anastomosis group had lower rate of gastric emptying disorder (0% vs. 6.9%, P=0.029), anastomotic fistula (7.3% vs. 18.4%, χ²=4.572, P=0.033), pneumonia (18.3% vs. 32.2%, χ²=4.294, P=0.038) and ICU management (4.9% vs. 16.1%, χ²=4.726, P=0.030).

CONCLUSIONThoracoscopic and laparoscopic esophagectomy with right neck anastomosis is safe and effective, can completely remove the tumor, at the same time, has less complications than left neck anastomosis, and improve the quality of life.
