Objective To study the expressions of metadherin (MTDH) and cyclinD1 in esophageal squamous cell carcinoma (ESCC) and their clinical significances. Methods The protein expressions of MTDH and cyclinD1 were detected by immunohistochemistry in 78 cases of ESCC. Results The positive expression rate of MTDH in ESCC was 71.79%(56/78) and the positive expression rate of cyclinD1 in ESCC was 74.36%(58/78). The expressions of MTDH and cyclinD1 were significantly correlated with the degree of differentiation and lymph node metastasis (both P< 0.05), but not with the age, gender of patients and depth of tumor invasion (all P> 0.05). Conclusion The over expressions of MTDH and cyclinD1 protein may involve in the occurrence and development of esophageal carcinoma, which play important roles in the invasion and metastasis of esophageal cancer.

Objective To investigate the biological function of IFN-λ in 7 human esophageal carcinoma cells. MethodsThe gene expression of IL-28α, IL-10β and antiviral molecule was examined with PCR. The MHC molecules expression and the profiles of cell cycle were analyzed with flow cytometer. Cell proliferation was evaluated with MTT assay. ResultsAll of esophageal carcinoma cells express the gene of II-28α and IL-10β. IFN-λ induced or augmented the gene expression of antiviral molecules, 2′5′-OAS and MxA. IFN-λ enhanced the MHC class Ⅰ molecule expression. IFN-λ inhibited the growth of esophageal carcinoma cells through the regulation of cell cycle distribution. ConclusionEsophageal carcinoma cells express the IFN-λ receptor complex. IFN-λ has the antiviral, anti-proliferative and immunoregulation activity.

Objective To evaluate the effectiveness of midazolam and morphine combined with TCI of propofol for endobronchial ultrasound-guided transbronchial needle aspiration ( EBUS-TBNA ). Methods Forty ASA Ⅰ or Ⅱ patients undergoing elective EBUS-TBNA were randomly divided into 2 groups according to the plasma concentration (Cp) of TCI of propofol (n=20 each): group Ⅰ Cp = 3 μg/ml (group P1) and group Ⅱ Cp = 4 μg/ml (group P2 ). Midazolam 0.03 mg/kg and morphine 0.05 mg/kg were administered iv followed by topical anesthesia of laryngopharynx with 4% hdocaine. TCI of propofol was started at 5 min before surgery. The patients kept spontaneous breathing during operation. MAP, HR and SpO2 were continuously monitored and recorded before anesthesia (baseline) and at 30 min after beginning of surgery and emergence from anesthesia. Arterial blood gas analysis was performed at 30 min after beginning of surgery and PETCO2 was measured at the end of surgery. The amount of 4% lidocaine used for topical anesthesia, the adverse reactions and the level of patient's satisfaction were recorded. Results PaO2 and pH value were significantly lower while PaCO2 and PET CO2 higher in group P2 than in group P1. There was no significant difference in the emergence time, the amount of 4% lidocaine used,the adverse reactions and the level of patient's satisfaction between the 2 groups. Conclusion TCI of propofol at Cp of 3 μg/ml can provide satisfactory anesthesia for EBUS-TBNA with less respiratory depression and more rapid emergence than that at Cp of 4 μg/ml.

Objective To discuss the safety, completeness and efficiency of the completely thoracoscopic lobectomy for non-small-cell lung cancer(NSCLC) which the tumor's diameter was larger than 5 centimeters. Methods From September 2006 to December 2009, 214 patients of NSCLC received completely thoracoscopic lobectomy in our center. There were 108 males and 106 females with median age of 62.5 years( range from 29 to 85 years). Patients were divided into two groups, group A ( diameter≥5 cm) and group B ( diameter <5 cm). We compared all the factors of age, gender, pathological type, location,rate of conversion to thorsctomy, operation time, blood loss, lymph node dissection, pathological stage, time of drainge, hospitalization, complications, overall survival and recurrence between two groups. Results Surgical procedures included lobectomy in 211 cases, composite lobectomy in 2 and pneumectomy in 1. All procedures were carried out safely without serious complication except one operative death result from respiratory failure. There were 30 cases in group A and 184 in group B. Age and gender were similar between two groups. The proportion of squamous cell carcinoma in group A was higher than it in group B (46.7% vs. 13.6% ,P <0.001 ). There were no differences in safety factors such as rate of conversion to thorsctomy( 16.67% vs. 7.61%,P =0.204), operation time[(214.0 ±58.1)min vs. (198.6 ±55.1)min, P=0.160], blood loss [(283.3 ±179.7)ml vs. (248.5 ±25.7)ml, P=0.559] and complications (13.33% vs. 14.67%,P=1.000). The completeness factors of lymph node dissection stages (5.0 ± 2.4 vs. 5.0 ± 1.7, P = 0.990 ) and numbers( 19.1 ± 10.1 vs.15.8 ± 8.8, P = 0.065 ) were equivalent between two groups. The estimated overall survival at 1 year was 81.25% for group A and 92.63% for group B ( P = 0.226). The recurrence of two groups was 3.45% vs. 2.23% (P = 0.532 ), respectively.Conclusion Completely thoracoscopic lobectomy can be done safely,completely and efficiently for non-small-cell lung cancer which the tumor's diameter was larger than 5 centimeters.

Objective To evaluate the value of autofluorescence bronchoscope (AFB) in airway examination in central type lung cancer. Methods From Sep 2009 to Mar 2010 ,29 patients ( 23 men , 6 women , median age 62.2 years , range from 34 to 81 years) underwent AFB procedure. There were 3 lesions located at trachea, 1 at right main bronchus, 9 at right upper lobe, 1 at right median bronchus, 1 at right middle lobe, 4 at right lower lobe, 1 at left main bronchus, 9 at left upper lobe.There were 21 preliminary diagnostic cases and 8 postoperative surveillance cases. All procedure was performed under combination of local anaesthesia and general anaesthesia. All patients underwent white light bronchoscopy followed by AFB procedure.All of the suspicious abnormal sites were recorded and biopsied for pathological examination. Results All procedures were safely performed without death or serious complications. 100 specimens were obtained for pathologic examination. Malignant lesion was diagnosed in 39 and non-malignancy in61. All malignant sites were detected by AFB, however WLB missed 12 sites.The sensitivity of AFB and WLB for malignancy were 100% and 69.2%, respectively. In 21 preliminary diagnostic cases,AFB detected all malignancy sites, but WLB missed 23 sites, in which 9 were malignant sites. In 8 rechecked patients, AFB detected all malignancy sites, but WLB missed 7 sites, in which 3 were malignant sites. Conclusion Autofluorescence bronchoscopy could be more accurate in judging the extent of the tumor invasion, more sensitive in finding multiple lesions in airway, more sensitive in detecting early cancer recurrence in postoperative surveillance patients.

Objective To optimize operative techniques of completely video-assisted thoracoscopic lobectomy by reviewing the experience of Peking University People's Hospital. Methods From September 2006 to August 2010, 408 patients (214 males,194 females) with median age of 58.6 years (range from 15 to 86 years) underwent completely thoracoscopic lobectomy. All procedures were conducted under general anesthesia with double lumen intubation. The thoracoscope was introduced through 7th or 8th intercostals space on the mid-axillaries line. The 4 cm long utility incision was made on the 4th or 5th intercostals space anterior axillary's line without rib-spreading. A third retraction incision located on the 7th or 8th intercostals space sub-scapular line. The surgeon stands on the ventral side of patient using an electrocautery hook and a suction device through the utility incision. Anatomic lobectomy was performed with systemic mediastinal lymph node dissection for lung cancer patients. Results All procedures were carried out smoothly with no case of serious complication. There was 1 case death because of respiratory failure of pulmonary fungal infection during the operative period. The average surgical duration was 195 minutes, and average blood loss was 249 ml with no blood transfusion required. There were 35 cases (8.6%) of conversion to open thoracotomy, including interference by lymph nodes, bleeding, inflammatory adhesion of Artery and large size tumors.The results of pathology show 322 cases of malignant disease and 86 cases of benign disease. Conclusion To grasp the core technique of completely thoracoscopic lobotomy may make the procedure undergone smoothly, and may shorten the learning curve.
