Objective To investigate the clinical characteristics,surgical strategy,pathological features and prognosis of pulmonary pleomorphic carcinoma.Methods The clinicopathological data of 23 patients with pulmonary pleomorphic carcinoma who underwent surgical resection from January 201 0 to March 201 4 in Tongji Hospital were collected.Results There were 1 6 male patients and 7 female pa-tients,with the male /female ratio of 2.3∶1 .The mean age of was 54(35 ~75)years old.A total of 1 7 pa-tients were heavy smokers and the mean smoking index was 688(400 -1 200).The initial main symptoms were cough,blood in phlegm and hemoptysis.It was difficult for fiberoptic bronchoscopy to confirm the di-agnosis.All patients underwent surgical resection,including 22 cases of radical resection and one case of biopsy.Microscopically,neoplastic epithelial cells and pleomorphic components were found in pulmonary pleomorphic carcinoma in 1 9 cases,and pleomorphic components only in the other 4 cases.Positive CK ex-pression in pleomorphic components was observed.The longest survival time was 1 8 months and the pa-tient was still alive.The median survival time was 1 2 months.Conclusion Pulmonary pleomorphic carci-noma usually occurs in middle-aged and elderly male smokers.Immunohistochemistry staining contribute to the diagnosis.The main treatment is surgery and the prognosis is poor.

Objective The difficulty of full thoracoscopic Ivor-Lewis is the lack of a safe and low cost anastomosis.By improving the surgical process,to explore the application of circular stapler in the intrathoracic esophagogastric anastomosis.The thoracoscopic operation mode of esophageal cancer changes from simply following the McKoewn procedure to Ivor-Lewis and McKoewn procedure.Methods Retrospective analysis 123 cases of implementation thoracoscopic esophageal cancer from July 2009 to February 2013,which including the cases of intrathoracic anastomosis and cervical anastomosis.Divided it into two groups:intrathoracic anastomosis groups,which including thoracoscopic esophagectomy resection,gastroesophageal anastomosis and anastomotic pedicled omentum embedding,the cervical anastomosis groups,which including thoracoscopic esophageal free and gastroesophageal neck anastomosis.To comparing the incidence of ARDS,postoperative hoarseness,anastomotic complications (Anastomotic leakage and anastomotic strictures within two months after surgery),guardianship time of ICU and postoperative hospital stay between the two groups.Results All the patients were no deaths.The cervical anastomosis group operative time was significantly lower than the intrathoracic anastomosis group.The incidence of anastomotic fistula and anastomotic stricture of intrathoracic anastomosis group was significantly lower than that of the cervical anastomosis group,total hospitalization time of the intrathoracic anastomosis group were significantly lower than that of the cervical anastomosis group,there is no significant differences in postoperative hoarseness and ARDS incidence between the two groups.Conclusion For the lower esophageal carcinoma,it is technically mature and safe to apply the circular stapler for Ivor-Lewis surgery and sleeve omentumembedding anastomotic technique in full thoracoscopic,and the technology should be widely applied; for the upper esophagealcarcinoma,McKoewn procedure should be applied.

Objective In order to improve the diagnosis accuracy , 18F-FDG PET/CT results of 169 cases of lung lesions were analyzed. Methods The data of 169 pathological diagnosed patients were collected. SPSS 18.0 was used for the data analysis. Results In 169 cases, 122 cases were proved malignant by patholog-ical diagnosis, in which 110 cases were correctly diagnosed by PET/CT. 47 cases were proved benign by patho-logical diagnosis, in which 15 cases were correctly diagnosed by PET/CT. The sensitivity was 90.2%, specificity was 31.9%, and the accuracy was 74.0%. Conclusion In order to improve the accuracy rate of PET/CT exam-ination and reduce the existence of false positive cases and false positive cases , we should estimate SUV (max) objectively and diagnose according to the size of the lesion , clinical history and laboratory results.

Insulin-like growth factors (IGF), regulated by their receptors and binding proteins, play a pivotal role in human cell proliferation, differentiation and apoptosis. Increasing evidence has revealed that IGF system is involved in the genesis and progress of various malignancies including lung cancer. Recent studies in regard to IGF axis expression in the lung cancer cell lines, pulmonary tissue samples and blood circulation of lung cancer patients have shown that the IGF axis may contribute to the transformation and progression of lung cancer. Several researches have shown that a number of drugs targeting the IGF receptor are being investigated in clinical trials and suggest a potential therapeutic efficacy. This article reviews the updates and progress in the research of IGF axis in lung cancer.

OBJECTIVETo analyze effect of treatment of lumbar intervertebral disc herniation with nucleus pulposus resection through small incision and lamina fenestration,and to explore operative advantage and mattars needing attention.

METHODSNinety-six patients with lumbar intervertebral disc herniation, including 48 males and 48 females with an average age of 46.4 years (ranging for 16-75 years) and an average course of 5 years (ranging from 1 month to 30 years), were treated with nucleus pulposus resection through small incision and lamina fenestration. The clinical effects were analyzed according to JOA scoring criteria of lower back pain.

RESULTSAll patients were followed up from 6 months to 3.5 years with an average of 1.2 years. According to JOA scoring criteria, 34 cases obtained excellent result, 55 good, fair 7. The rate of excellent and good was 92.71% and the mean improvement rate was 54.53%.

CONCLUSIONNucleus pulposus resection through small incision and lamina fenestration can obtain satisfactory outcome in treating lumbar intertebral disc herniation. The incidence of lumbar instability and postoperative complications were low. It is one of the better method for the treatment of lumbar intertebral disc herniation.

Objective To investigate the security and efficacy of one stage and bilateral resection of thymic tissue and clearance of mediastinal fat by uniportal-video-assisted thoracic surgery(VATS) to cure patients with myasthenia gravis(MG).Methods A number of 131 patients with MG who underwent resection of thymic tissue and clearance of mediastinal fat by VATS in one single center from February 2009 to December 2013 were selected in this retrospective study.76 patients underwent unilateral resection of thymic tissue and clearance of mediastinal fat by three portal VATS from February 2009 to March 2012 and 55 patients underwent one stage and bilateral resection of thymic tissue and clearance of mediastinal fat by small uniportal-VATS from April 2012 to December 2013.The time for operation,the bleeding volume during operation,the volume of postoperative drainage and drainage time,the improvement of symptoms,the postoperative pain,hospital stays and the occurrence of myasthenia gravis crisis were compared between the two groups.Results The general condition and pathological type did not have significant statistical differences between the two groups.The operating time in the uniportal-VATS group was significantly longer than that in three portal VATS group,but the pain was lighter,and the hospital stay was shorter.There were no significant differences between groups in terms of blood loss,postoperative drainage time,and volume of drainage.The follow-up was from 32 to 90 months,and 118 (90.08％)patients completed the follow up.94.5 ％ of the patients in uniportalVATS group acquired complete stable remission(CSR),while it was 84.2％ in three portal VATS group(P ＜ 0.05),and the uniportal-VATS group had lower rate of myasthenic crisis (P ＜0.05).Conclusion One stage and bilateral resection of thymic tissue and clearance of mediastinal fat by small uniportal-VATS is safe and effective with shorter hospital stay and less pain,and it can get higher CSR and less myasthenic crisis,its efficacy is superior to traditional three portal VATS.
