Chinese Journal of Postgraduates of Medicine 2008;31(29):4-7
Objective To investigate the factor that related to neoplasm from the clinicopathologic character of gallbladder polyps, and identify the reciprocal effectiveness of these factors. Method Three hundred and forty-seven patients who were underwent operation with gallbladder polypoid lesions were reviewed. Results Logistic regression analysis showed, only 5 parameters were significant for the prediction of neoplastic lesions, including age of the patient (P =0.015), the number of polyps (P=0.018), the maximal diameter (P=0.000), echo property (P=0.000), as well as the position of polyps (P=0.030),of which the maximal diameter was the best one to predict the neoplasm polyps. Further analysis with HOC curve showed that 0.925 cm, the diameter of polyps, was the critical point to calculate the polyp was neoplasm or not. Conclusions Age of the patient , the number of polyps , the maximaldiameter, the position of polyps, and echo property are independent factors in predicting gallbladder neoplastic lesions. The size of the polyps is the most significant one among the factors to predict gallbladder neoplasm with its critical point of 0.925 cm.

Objective To explore the design and application of the multifunctional treatment beds on patients′ position compliance and comfort after intraocular retinal reattachment surgery. Methods Eighty-six patients needing special position nursing after intraocular retinal reattachment surgery were randomly divided into experiment and control groups. The former received the special multifunction treatment beds while normal ward beds were used for the control patients . The position compliance , comfort and the complications were observed one month after surgery. Result The position compliance and the degree of comfort in the experiment group were significantly better than those in the control group and the complication rate was significantly lower than that of the control group (all P<0.05). Conclusion The special multifunction treatment beds can be effective in increasing the patients compliance in positions and compliance as well as reducing postoperative complications and increasing the operation success rate.

ObjectiveTo analyze intrathoracic or extrathoracic recurrence pattern after surgical resection of thoracic esophageal squamous cell carcinoma (TESCC) and its help for further modify and improvement on the target of postoperative radiation therapy. Methods One hundred and ninety-five patients who had undergone resection of TESCC at the Cancer Hospital,Chinese Academy of Medical Sciences enrolled from April 1999 to July 2007.Sites of failure on different primary location of esophageal cancer were documented.Results Patients with upper or middle thoracic esophageal cancer had higher proportion of intrathoracic recurrence.Patients with lower thoracic esophageal cancer had more intrathoracic reccurence and abdominal lymph node metastatic recurrence.Histological lymph node status has nothing to do with intrathoracic recurrence,supraclavicular lymph node ( SLN ) metastasis or distant metastasis ( χ2 =1.58,0.06,0.04,P =0.134,0.467,0.489,respectively),whereas the chance of abdominal lymph node metastases in N positive patients was significantly higher than that in N0 patients (28.7%: 10.6%,χ2 =9.94,P =0.001 ),and so did in middle thoracic esophageal cancer ( 20.0%: 5.6%,χ2 =5.67,P =0.015). Anatomic recurrence rate of patients with proximal resection margin no more than 3 cm was significantly higher compared to those more than 3 cm (25.0%: 11.3%,χ2=5.65,P=0.019).ConclusionsMediastinum is the most common recurrence site.According to recurrence site,the following radiation targets are recommended:when tumor was located at the upper or middle thoracic esophagus with negative N status,the mediastinum,the tumor bed and the supraclavicular region should be included as postoperative RT target;when tumor was located at the middle thoracic esophagus with positive N or located at the lower thoracic esophagus,the abdominal lymph node should be added.If the proximal resection margin was no more than 3 cm,the anastomotic-stoma should be included.

Polyamine biosynthesis is controlled primarily by ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase(AdoMetDC). Antisense ODC and AdoMetDC sequences were cloned into an adenoviral vector (Ad-ODC-AdoMetDCas). To evaluated the effect of recombinant adenovirus Ad-ODC-AdoMetDCas which can simultaneously express both antisense ornithine decarboxylase (ODC) and sadenosylmethionine decarboxylase (AdoMetDC), the human lung cancer cell line A-549, was infected with Ad-ODC-AdoMetDCas as well as with control vector. Viable cell counting, determination of polyamine concentrations, cell apoptosis,and Matrigel invasion assays were performed in order to assess properties of tumor growth and invasiveness. Furthermore,Ad-ODC-AdoMetDCas's anti-tumor effect was also evaluated in vivo in a nude mice xenograft model. It was demonstrated that adenovirus-mediated ODC and AdoMetDC antisense expression could inhibit tumor cell growth, lead to cell apoptosis and reduce tumor cell invasiveness. Polyamine levels were significantly decreased in Ad-ODC-AdoMetDCas-treated cells compared with controls.This adenovirus also induced tumor regression in established tumors in nude mice. It was suggested that as a new anticancer reagent,the recombinant adenovirus Ad-ODC-AdoMetDCas holds promising hope for the therapy of lung cancers.
