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 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 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.

ObjectiveTo investigate the clinical significance and characteristics of recurrent laryngeal nerve lymph node metastasis of thoracic esophageal cancer.MethodsOne hundred and twenty-four patients who had undergone thoracic esophageal resection with recurrent laryngeal nerve lymph node dissection in our hospital from March 2007 to February 2010.All clinical data were retrospectively analysed.ResultsRecurrent laryngeal nerve lymph node metastasis was found in 34 of 124 cases,with the metastatic rate of 27.41% (34/124).The left recurrent laryngeal nerve lymph node metastasis was 16.13% and the right was 8.06% .The recurrent laryngeal nerve lymph node metastasis was found in 9 patients with the upper segment esophageal cancer,20 with middle third esophageal cancer and 5 with lower segment esophageal cancer,6 patients with T2 disease had recurrent laryngeal nerve lymph node metastasis,while 27 with,T3 disease.Also there were 4,13,17 cases with metastasis in well-differentiated,moderately differentiated,poorly differentiated respectively.Poorly differentiated esophageal carcinoma was more susceptible to recurrent laryngeal lymph node metastasis than well-differentiated and moderately differentiated esophageal carcinoma.Recurrent laryngeal nerve injury was found in 11 cases,7 cases of them recovered.ConclusionNearly 1/3 of patients with esophageal carcinoma have recurrent laryngeal nerve lymph node metastasis,especially for tumor located in the upper third esophagus,poor differentiation or deep invasion (T2 or more) of esophageal carcinoma were more susceptible to recurrent laryngeal nerve lymph node metastasis.

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 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.
