Objective:To correct the characterizations of MDCT radiation dose by exploring the relationship between CTDIw,∞ and CTDIw.Methods: CTDI100 and CTDI∞ were measured under the conditions of different collimations, pitches and tube voltages of Siemens Definition Flash CT, and CTDIw and CTDIw,∞ were calculated.Results: There were significant differences between CTDIw and CTDIw,∞ which were measured at 0.05 level. And there were no significant differences between CTDIw,∞ after corrected and CTDIw,∞ which were measured at 0.05 level.Conclusion:The characterizations of MDCT which were commonly used were not accurate enough. The result after correction were very closed to the real CTDIw,∞. This showed that the method to correct CTDIw of Siemens Definition Flash CT was mostly accurate. And methods to correct CTDIw of other MDCT needed to be further studied.

Objective: The purpose of the current study was to investigate the correction coefficient of the characterizations of multi-detector CT (MDCT). Methods: The dose profile of Siemens SOMATOM Definition Flash CT scanner was measured with CT-SD 16 detector under the conditions of different collimations, pitches and tube voltages in phantoms of different diameters, and the ratio between weighted CTDI∞and weighted CTDI100 was calculated. Results:The ratio between weighted CTDI∞and weighted CTDI100, which is growing for increasing beam collimation, was found to range from 1.123 to 1.162 in head phantom and range from 1.118 to 1.173 in body phantom. Conclusion: For MDCT, the use of CTDI100, which is one of the most commonly used characterizations of CT, has always underestimated the levels of radiation dose. Therefore, CTDI100 should be corrected.

OBJECTIVE To analyze the correlation between number of tissue eosinophils(Eos) and blood Eos levels in patients with chronic rhinosinusitis with nasal polyps(CRSwNP), and to investigate if tissue and blood eosinophilia predicts disease severity and prognosis in CRSwNP. METHODS A retrospective analysis of 102 patients, who diagnosed with CRSwNP was carried out in this study. Surgical specimens were evaluated for degree of tissue Eos, which was compared with blood Eos. Patients were divided into two groups according to the results of endoscopy one year after surgery: recurrent and non-recurrent group. Statistical analysis was performed to compare tissue and blood Eos and CT Lund-Mackay scores. RESULTS Blood and tissue Eos in recurrent group was significantly higher than that in non-recurrent group(P=0.032, 0.033, 0.017). There was not a statistical difference of CT scores between two groups(P =0.089). There was a significant correlation between tissue Eos and absolute number of blood Eos(r=0.637, P=0.000) as well as between tissue Eos and percentage of blood Eos(r=0.542, P=0.000). However Eos and CT scores were not correlated statistically(P>0.05). CONCLUSION Blood Eos levels can predict the degree of Eos infiltration in nasal polyps. Blood and tissue Eos correlate with prognosis.

OBJECTIVE:To analyze the resistance of the main pathogens in our hospital to antimicrobials for clinical reference of rational use of antimicrobial agents. METHODS:The antibiotic resistance of the clinical pathogens in our hospital in 2008 was retrospectively analyzed. RESULTS:Of the total 938 clinical pathogenic bacteria isolated in our hospital,the most common pathogens(leading the first 10 places)were E. coli,staphylococcus aureus,enterobacter spp,staphylococcus epidermidis,pseudomonas aeruginosa,Klebsiella,acinetobacter,enterococcus,hemolytic streptococcus and bacillus proteus. CONCLUSION:Clinicians should use antimicrobial agents rationally to reduce the antibiotic resistance.

Objective To establish the animal model of acute intracranial hypertension,investigate the changes of transeranial Doppler patterns in raised intraeranial pressure so that the necessary experimental evidence will be provided to clinical experience for monitoring intraeranial pressure (ICP) and cerebral perfusion pressure (CPP) using transeranial Doppler non-invasively. Methods Acute intraeranial hypertension was induced by inflating the balloon inserted into the epidural space. Blood flow velocity of basilar artery was measured with transcranial Doppler and intracranial pressure as well as cerebral perfusion pressure was measured. Results With progressive increase of intracranial pressure five characteristic flow patterns were observed, appearing in the following order: high resistance pattern, systolic flow, retrograde diastolic flow, very small systolic flow and zero flow. Conclusions Analysing patterns of TCD may be helpful for evaluating ICP and CPP qualitatively. The animal model is simple and strict so that it is worthy of being spreadcd.

Gastric cancer is one of the most common malignant tumors in China, and its pathogenesis is complex. At present, there is no good method for the diagnosis and treatment of gastric cancer. However, studies have shown that microRNA (miRNA) has abnormal expression in gastric cancer, which participates in the regulation of gastric cancer related genes, and has an impact on the occurrence, development, diagnosis and treatment of gastric cancer. This paper aims to review the relationship between miRNA and the diagnosis and treatment of gastric cancer, as well as the drug resistance in the treatment, so as to lay the foundation for the follow-up research and clinical diagnosis and treatment.

Objective To compare imaging quality and radiation dose on full-field digital mammography (FFDM) system and dual-sided reading CR mammography (DSCRM) system.Methods The TRM of ALVIM statistics phantom was exposed by FFDM system and (DSCRM) with the same radiation dose.The exposure parameters and the entrance surface dose (ESD) were recorded.Then,the phantom was exposed by DSCRM system with different mAs and same kV,and the ESD was recorded.The images obtained above were read by three radiologists on the monitor of diagnosis work station with the same window width and window level.The evaluation of the images were given using a five-level confidence scale.ROC curves were drawn and probability Pdet were calculated.Results The ROC analysis of microcalcifications and masses showed A(z) values of 0.730-0.925 and 0.670-0.945 for FFDM,and 0.632-0.815 and 0.575-0.785 for DSCRM when the radiation dose is 1.36 mGy.The radiation dose with DR system could be reduced compared with dual-sided reading CR system at the same probabilities Pdet,the ESD reduced from 1.63 mGy to 1.36 mGy by 19.8％,the AGD reduced from 0.65 mGy to 0.56 mGy by 16.0％.Conclusions The observable details with FFDM system were proved to be superior to DSCRM system at the same radiation dose.With the similar image quality,the radiation dose of FFDM system was less than the DSCRM system.
