Objective:To explore the relationship between false increase of white blood cell count and fragility of erythrocyte membrane in automatic whole blood count. Methods: The osmosis and incubation osmosis fragility of erythrocyte membrane in controls 1 (Group 1, n =30)and white blood cell count false increase (Group 2, n =30) were detected by the operation rule of the group of clinical examination. Results: Compared with the results of Group 1 frogility of erythrocy to membrane in infectious hepatitis,livercirrhosis and liver cancer were reduced( P

Objective To explore the histocompatibility and plasticitity of hydroxyapatite/high-density polyethylene composite (HMPE). Design Experimental study. Participants Forty-five rabbits. Methods Rabbits were randomly devided into HA/PE, HA and PE surgical groups, every group included 15 rabbits. Osteoeetomy of orbital rim and implantation (HA/PE, HA and PE materials were used) were performed on 3 groups of the rabbits. At 1st week, 4th week, 8th week, 12th week and 24th week of postoperation, we took out the samples from the rabbits separately in each group and did histopathologic and electron microscope examinations. Main Outcome Measures Physical signs of the implant combination with the bone. The bone cell appeared in the implants. Results After 12 weeks, the calcium salts deposit like bone plate with some osteoblast inside the HA/PE implants was observed. After 8 weeks, the calci- um salts deposit inside the HA plants was observed. In the PE implants, nothing could be seen but some fibrous connective tissue. Conclusion HMPE is an ideal repair material especially for orbital bone.

Objective To discuss the application effects of CBI teaching method in medical English Teaching of respiration medicine. Methods Dividing 120 students of Grade 2009 in Jining Medical College into two groups including control group (60) and experimental group (60). The tradi-tional teaching method was adopted in the control group and CBI teaching method was adopted in the experimental group. After finishing the courses, medical professional English level test and standard-ized patients test were applied in the two groups. Students' English studying interests and autonomous English learning ability were also investigated by questionnalres. SPSS 17.0 software was used for sta-tistical analysis, and the data were processed by t test and 字2 test, with the level of a test equal to 0.05. Results The medical professional English level test scores, standardized patients test scores and the total average scores of autonomous English learning ability in experimental group were respectively [(81.97±4.91), (80.33±5.85), (3.88±0.38)], and they were significantly higher than those in the control group [(70.40±4.78), (70.48± 4.79), (2.98±0.26), with P values below 0.01]. Satisfaction degrees in the improvement of learning motivation, learning time, learning method, learning attitude and dealing with study difficulties in experimental group were better than those of control group (χ2=13.084, 8.000, 13.297, 11.627, 13.374, P=0.000). Conclusion CBI teaching method is better than traditional teaching method and it transfers English learning into the learning of professional knowledge and skills of respiratory medicine, stirs the interests of students, improves their autonomous English learning ability and strengthens their abilities to learn and apply English language.

In order to cultivate advanced person with ability,we should teach students some theoretics and more practical skill during microbiology teaching. after we using the measures “examining on theoretics and practical skill that must be mastering in the lesson”. Students had been more interested in microbiology,and advanced of knowledge. So “examining on theoretics and practical skill that must be mastering in the lesson” is better method in teaching of Microbiology in Occupation technique college.

Objective To investigate the efficient methods used for tracing endothelial progenitor cells(EPCs)after transplantation in injured lung tissue.Methods Thirty clean grade healthy syngeneic SD female rats were divided into three experimental groups(n =10):(1)sham group,rats treated with intravenous phosphate-buffered saline(PBS)instead of lipopolysaccharide(LPS)followed by EPCs graft;(2)PBS-treated group,rats treated with intravenous PBS after intravenous injection of LPS to produce acute lung injury;(3)EPC-treated group,rats treated with EPCs after intravenous injection of LPS to produce acute lung injury.The transplanted EPCs were got from the same genetic species of the SD male rats.Rats of each group were sacrificed 7 days after EPCs transplantation.Their whole lung tissues were harvested to detect the expression of Y-chromosome by using hybridization in situ and RT-PCR assay.Statistic package of SPSS16.0 was used for the data analysis and significant differences between means were evaluated by ANOVA analysis.Results Compared with the other two groups,positive signals of sex-determining region y were found in lung endothelium from the EPC-treated group.Conclusions Y chromosme specific probe can be one of efficient methods for tracing stem cells after transplantation.

From the perspective of clinical doctors, in the teaching idea, national policy, school policies and different stages of clinicians cultivation , the article introduced the concept of translational medicine in the process of the clinical doctors tralning in the United States. It described US medical schools' (U.S. Virginia University School of medicine, for example) implementation ap-proach of translational medicine ideas in different stages, such as before entering school, during the period of school, practice exam and physician clinician tralning. It provided the reference for the de-velopment of translational medicine education in the process of China clinician education and tralning, including:medical students' integration into the related clinical research in preschool through volunteer service, the choice of multiple combination model of clinical science and basic research, interdisci-plinary examination of medical practitioners and the provisions of the research work in resident and specialist tralning stage.

To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.

Objective To detect left atrial (LA) function and left ventricular (LV)-LA coupling using vector flow mapping (VFM) and two-dimensional tissue tracking (2DTT) echocardiography in patients with diabetes.Methods A total of 51 patients with type 2 diabetes (DM group) and 38 healthy volunteers (control group) were studied.LA and LV strain were assessed by 2DTT.The energy loss (EL) of LA and LV during ventricular systole (ELs),early diastole (ELed),and atrial contraction (ELac) were measured by VFM.Results LVEL in DM group was significantly increased compared to that in control group (P<0.05).LAELs and LAELed in control group were higher than those in DM group (P<0.05);while LAELac decreased in control group (P<0.05).Multivariate regression analysis identified E and LVELed as independent predictors of LAELed;Peak torsion,LA peak systolic strain and LVELac were independent predictors of LAELac.Conclusions The reservoir and conduit function of LA are impaired in patients with DM,while the pump function increases as a compensation.Abnormal LA-LV coupling also appears in patients with DM.
