BACKGROUNDMediastinoscopy has experienced a renaissance due to the introduction of neoadjuvant treatment protocols and recognition of the limitations of noninvasive mediastinal staging of lung cancer by CT and PET. The aim of this study is to determine the value of video-mediastinoscopy in mediastinal staging of lung cancer.

METHODSA total of 60 patients who underwent video-mediastinoscopy for known or suspected lung cancer were retrospectively reviewed. There were 52 cervical mediastinoscopies, 2 parasternal mediastinoscopies and 6 combined procedures. All the patients were found to have enlarged mediastinal lymph nodes on radiographic examination of the chest (more than 1.0cm on its shortest axis).

RESULTSOf the 60 patients, 42 patients were found with N2 or N3 disease on video-mediastinoscopy and then were confirmed pathologically. The other 18 mediastinoscopy-negative patients underwent thoracotomy for pulmonary resection and mediastinal lymph node dissection in the same operative session, in which thoracotomy-proven N0 was found in 17 patients, and N2 in 1 patient (false-negative result by video-mediastinoscopy). The sensitivity, specificity, and accuracy of video-mediastinoscopy for mediastinal staging of lung cancer were 97.7%, 100% and 98.3%, respectively. In the entire group of 60 patients, there was 1 complication (1.7%) , and no perioperative death.

CONCLUSIONSVideo-mediastinoscopy is a highly effective and safe procedure. It can be used routinely in mediastinal staging of lung cancer.

Objective:To detect the anti-cancer component, trans-resveratrol in red wine by high performance liquid chromatography, and to determine the influence of environmental factors on its content. Methods: A method for determining trans-resveratrol in red wine by HPLC is described. The operating conditions were ZORBAX-C18 column(4.6 mm×250 mm, 5μm) at room temperature, 30%acetonitrile as mobile phase at a flow of 1ml/min and UV detection at 306 nm. Results:The content of trans-resveratrol in Changyu dry red wine and Great Wall Claret Cabernet are (1.01±0.03)mg/L and (2.36±0.02)mg/L, respectively. The results show that, sunlight, high temperature and poor seal condition can decrease the content of trans-resveratrol. Conclusion:The content of trans-resveratrol varies in different brands of red wine. Red wine should be stored in cool, dark and sealed conditions.

Objective To evaluate if the enteral nutrition have effect on the immune function and in- flammatory reaction after operating about gastric carcinoma.Methods 58 postoperative patients suffering from stomach cancer and colon cancer were randomly divided into the EN group and the TPN group.On the first postoperative day,nutrition fibre were given via nasal intestinal tube,increasing the capacity and drop- ping speed day by day until patients can eat liquid diet.While patients in the TPN group didn't eat anything until enterokinesia completely recovered.Observing on preoperative day 1 and on postoperative day 3 and day 8 respectively to check IgA,IgG,IgM,C3,C4,CRP,LYM,LYM%,TP,ALB,PA.Results The results showed that on the postoperative day 8,the target ascension extent was higher than that in the PN group.The statistical significance was very obvious(P

0.05).Conclusions There is imbalance of Th1/Th2 cells in CHB children.Th1 cytokines are positively correlated with hepatic inflammatory activity.In the course of disease,Th2 cytokines are predominant and they have a correlation to the chronic prognosis of the illness.So we can conclude the degree and prognosis of disease by observing the change of Th1/Th2 cytokines in CHB children.

Objective To evaluate the imaging features of phyllodes tumor of the breast.Methods 35 patients with phyllodes tumor of the breast confirmed by surgery and histopathology were collected.All clinical and imaging findings were analyzed.Results 35 cases with 36 lesions were classified as benign (1 9 lesions),borderline (8 lesions),and malignant (9 lesions).The typical ap-pearances on mammography were ellipse (1 6/36)or lobulated (20/36)mass.Most of them were high density (30/36)and clear boundary (28/36).No evidence of calcification,spiculated margin,skin thickening,nipple retraction and enlargement of axillary lymph nodes were detected.On MRI,1 lesion presented as lobulated mass with nonuniform hypointensity on T1 WI,hyperintensity on T2 WI and DWI.The time-intensity curve was Ⅱ type on dynamic contrast enhancement MRI.Conclusion The clinical and ima-ging features of phyllodes tumor are characteristic.These features are helpful to preoperatively diagnose,the final diagnosis would confirmed by histopathology.

To investigate the inherent characteristics of the pathogenic Yersinia enterocolitica. Polymerase chain reaction (PCR),analysis of DNA sequence,randomly amplified polymorphic DNA (RAPD) were used to study the pathogenic and nonpathogenic 10 strains of Yersinia enterocolitica. The Pathogenic Yersinia enterocolitica of serotyps 0∶3?0∶9 and 0∶5,27 were confirmed containing pathogenic gene of adherent invasion locus(ail) and their DNA fingerprints were much more similar,and it was also found that the serotype 0∶22 contained ail gene whose fingerprints was partly similar with the pathogenic ones in molecular structure. The pathogenic Yersinia enterocolitica strains were similar in the inherent and polymorphic. The serotype 0∶22 may have relativly evaluated association with pathogenic Yersinia enterocolitica, which is possible that it got potentially pathogenicity.
