Objective To investigate the water equivalent of two solid water phantoms.Methods The X-ray and electron beam depth-ion curves were measured in water and two solid water phantoms,RW3 and Virtual Water.The water-equivalency correction factors for the two solid water phantoms were compared.We measured and calculated the range sealing factors and the fluence correction factors for the two solid water phantoms in the case of electron beams. Results The average differenee between the measurled ionization in solid water phantoms and water was 0.42%and 0.16%on 6 MV X-ray(t=-6.15.P=0.001and t=-1.65,P=0.419)and 0.21%and 0.31%on 10 MV X-ray(t=1.728,P=0.135 and t=-2.296,P=0.061),with 17.4%and 14.5%on 6 MeV electron beams(t=-1.37.P=0.208 and t=-1.47,P=0.179)and 7.0%and 6.0%on 15 MeV electron beams(t=-0.58.P=0.581 and t=-0.90,P=0.395).The water-equivalency correction factors for the two solid water Dhantoms varied slightly largely,F=58.54,P=0.000 on 6 MV X-ray,F=0.211.P=0.662 on 10 MV X.ray,F=0.97.P=0.353 on 6 MeV electron beams,F=0.14,P=0.717 on 15 MeV electron beams.However,they were almost equal to 1 near the referenee depths.The two solid water phantoms showed a similar tread of Cpl increasing(F=26.40,P=0.014)and hpl decreasing(F=7.45,P=0.072)with increasing energy.Conclusion The solid water phantom should undergo a quality control test before being clinical use.

Objective:To study the ethical attitude of infertility patients and the public towards the artificial insemination technology,with the aim of its better clinical application.Methods:A questionnaire among 220 infertility patients and 720 persons of different social walks,followed by a contrastive study of the results.Results:There is distinctive difference(P

Objective To evaluate the effect of recombinant expressing plasmid pCMV-KAI1 on the proliferative ability of PANC Ⅰ and MiaPaCa Ⅱ pancreatic cancer cells, and to observe the suppress metastatic mechanism of KAI1 gene in the malignancy.Methods The plasmid pCMV-KAI1 was transfected into the human pancreatic cancer cell lines PANC Ⅰ and MiaPaCa Ⅱ with liposome. The proliferative ability of these two pancreatic cancer cell lines were analyzed with MTT and colony-forming test, the cycle pattern was assayed by flow cytometry.Results After KAI1 expressing plasmid tranfected into PANC Ⅰ and MiaPaCa Ⅱ, the cell growth rates of the two cell lines were reduced by 40.59% and 65.84% respectively compared with the control cells (P

objective To investigate the effect of the prognosis of multiple organ dysfunction syndrome(MODs) through APACHE Ⅱ and APACHE Ⅲ.Methods The relations of APACHEⅡ,APACHEⅢ,the occurrence rate and number of organs failure and the dangerous extent and prognosis of MODS are studied between survival group and death group through the review research of 45 cases of MODS.Results APACHE Ⅱ andⅢ,age and genrating rate of failure organS are significant difference between surviral group and death group(P＜0.05)in MODS.The predicting correlation of APACHE Ⅱis not significant difference between number of organs failure and mortality of MODS(P＞O.05),but the predicting correlation of APACHE Ⅲ is significant difference between number of organs failure and mortality of MODS(P＜0.05).Conclusion The study showed APACHEⅢis better than APACHEⅡ on the dangerous extent and prognostic evaluation in MODS.

OBJECTIVE:To optimize freeze-drying technology of albendazole nanosuspension so as to prepare albendazole nanometer powder. METHODS:By adopting freeze-drying method,with particle size and Zeta potential as the indexes,single fac-tor test and verification were made on pre-freezing temperature and the type,ratio and mass fraction of cryoprotectants,and then the albendazole nanosuspension prepared by liquid phase precipitation method was made into albendazole nanometer powder. RE-SULTS:When the pre-freezing temperature was-20℃and the cryoprotectant was 4%glucose-mannitol(3∶7),the average parti-cle size of the prepared nanometer powder was (208.03 ± 2.13) nm,and average Zeta potential was (-15.53 ± 0.18) mV. CON-CLUSIONS:Albendazole nanometer powder with better particle size and potential can be prepared by freeze-drying technology.

Objective To compare the value of color Doppler echocardiography in the diagnosis of coarctation of the aorta (COA) in comparison with CT angiography (CTA). Methods Ninety-two patients with COA were retrospectively analyzed that were confirmed by surgery from January 2009 to September 2013 and diagnosed by color Doppler echocardiography and CTA. Results Among 92 COA patients conifrmed by surgery, 87 patients were diagnosed correctly by echocardiography while 91 patients were diagnosed by CTA, and the accuracy of echocardiography and CTA were 95%(87/92) and 99%(91/92), respectively without significant difference (χ2=1.550, P=0.213). According to surgical findings, there were 222 anatomic abnormalities including 110 intra-cardiac, 13 heart-vessel connection and 99 vessel abnormalities. For 110 intra-cardiac abnormalities, echocardiography detected all abnormalities while CTA found 92 with 18 missed including 11 valve or valve ring lesions, 3 patent foramen ovale, 2 atrial septal defect, 1 ventricular septal defect and 1 endocardial cushion defect. The accuracy of echocardiography for intra-cardiac abnormalities was signiifcantly higher than that of CTA (100%, 110/110 vs 84%, 92/110,χ2=18.801, P=0.000). CTA and echocardiography detected all abnormalities of heart-vessel connection. For 99 vessel abnormalities, CTA showed an accuracy of 98%(97/99) with 2 missed lesions including 1 collateral circulation between the aorta and the pulmonary artery and 1 membranous narrow of the aorta, while echocardiography misdiagnosed 1 COA as interruption of aortic arch and missed 15 lesions, including 4 COA, 3 collateral arteries, 2 patent ductus arteriosus, 2 aberrant right subclavian artery, 2 brachiocephalic vein abnormality, 1 partial anomalous pulmonary venous drainage and 1 persistent left superior vena cava. The accuracy of CTA for detection of vessel abnormalities was signiifcantly higher than that of echocardiography (98%, 97/99 vs 84%, 83/99,χ2=11.350, P=0.000). Conclusions Both CTA and echocardiography are effective diagnostic modalities for COA and CTA is superior to echocardiography for detecting vessel anomalies whereas echocardiography is superior to CTA for detecting intra-cardiac abnormalities. The combination of both modalities will provide more accurate information for clinical diagnosis.
