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 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.

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 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.

Objective:To systematically evaluate the effectiveness of early enteral nutrition after hepatectomy of hepatic carcinoma in China.Methods:The database such as CNKI,VIP,WANFANG DATA and CBM were searched electronically to collect the randomized controlled trials about enteral nutrition (EN) versus parenteral nutrition (PN) after hepatectomy.Meta-analyses were performed using the RvmanS.3 software.Results:Seven randomized controlled trials involving 460 patients were included.The analysis showed that the EN had significantly higher levels of albumin (WMD =1.17,95％ CI:0.45 ～ 1.89,P =0.001) and lower levels of aminotransferase (WMD =-3.95,95 ％ CI:-7.08 ～-0.81,P =0.O1) than those in the control group.The time of gastrointestinal function recovery in EN group was shorter than that in PN group.There was no significant difference in body weight and adverse reactions of gastrointestinal tract.Conclusion:Early enteral nutrition support for patients after hepatectomy of hepatic carcinoma shows certain advantages,which can improve the nutrition status and be in favor of the recovery of liver and gastrointestinal function.

Objective To investigate the distribution of characteristics,clinical manifestations,laboratory parameters and activity index of patients with systemic lupus erythematosus (SLE) and to determine their role in helping to make correct clinical diagnosis and disease the activity evaluation of SLE.Methods Collect the data of 1037 SLE patients of Ningxia Medical University Affiliated Hospital from January 2006 to June 2010.Data were analyzed with t test and Chi-square test.Results Over the past three years,there were more and more patients were admitted year by year.Among the 1037 cases of SLE patients,most of them 20-40 year-old woman,accounting for 67.5％ of the whole patient population,with a male to female ratio was 1:8.26.Joint pain was the most common initial symptom,accounting for 54.3％,followed by skin rash,accounting for 48.2％.Decreased complement C3 level and platelets counts, proteinuria,and positive anti-dsDNA antibody could be used as indicators for early diagnosis of SLE.SLEDAI activity score higher than 9 were presented in 26.0％ of patients.Factors that could impact the final score of SLEADI were fever,arthritis,skin rash,proteinuria,low complement levels,high titers of anti-dsDNA antibody,pleurisy,alopecia,mucosal ulcers,pericarditis,mental illness and decreased platelets count.Patients with active disease had a higher accidence of fever,arthritis,skin rash,lung damage,alopecia,mucosal ulcers,heart damage,mental illness and renal damaged,low complement levels,high level of anti-dsDNA antibody titers and elevated erythrocyte sedimentation rate.Conclusion SLE is a multi-system disease with multiple organ involvement,with characteristic clinical symptoms and immunological abnormalities,thus early diagnosis is very important.Understanding the characteristics of the diseases,correct judgement of the disease activity,reasonable and effective treatment all can delay the development of organ damage and improve the prognosis.

In order to improve the production of agro-antibiotic 2-16,the producing strain(Streptomyces ahygroscopicus var.huangshanensis) was treated by protoplast regeneration,ultraviolet radiation,NTG mutagenesis and low energy C~(+) ion implantation.At last,a high-yield strain No.515 was obtained.The production of ~()No.515 was increased by 223.10%.By using Plackett-Burman design and Response Surface Analysis provided by SAS software,the cultivation condition of No.515 was optimized.The amount of agro-antibiotic 2-16 was increased by 38.53% when the strain No.515 was cultivated in the optimum medium instead of the initial one.
