Objective To research on the clinical value of conization of cervix in CINⅢby pathologic histol- ogy with the help of colposcope.Methods 36 cases of CINⅢwere analysed by pathologic histology with the help of colposcope.Results Of all 36 eases diagnosed as CINⅢ,there were 3 cases diagnosed as invasive carcinoma and mi- croinvasive carcinoma.25 cases diagnosed as CINⅢ,8 cases diagnosed as CINⅠ～Ⅱ,and chronic cervicitis after conization of cervix.Conclusion Conization of cervix should be taken for CINⅢby pathologic histology with the help of colposcope.

Objective:To study the mandibular movement characteristics of subjects with severe tooth wear (TW).Methods:30 TW patients (24 men, 6 women, mean age 51 years) were served as TW group and 10 subjects with individual normal occlusion were served as control group (7 men, 3 women, mean age 40.5 years). All cases were examined by means of K6-1 Evaluation System manufactured by Myotronics US. The traces of the mandibular opening-closing movement and border movement were recorded.Results:During the movement from mandible posture position(MPP) to intercuspal position(ICP), the TW patients showed unstable characteristic. The velocity showed no significant difference between the two groups during opening and closing, but the congruence and smoothness of traces during the mandibular opening-closing and border movements in the TW patients were a little worse than the controls; and the TW patients had less mandibular movement index(MMI) than the controls(P

Objective To assess the correctness of statistical methods applied in the research papers of Chinese Journal of Nuclear Medicine and Molecular Imaging (CJNMMI) and to provide suggestions for further improving.Methods Papers were obtained from CJNMMI by multi-stage sampling method between 2007 and 2011 according to the number of journals and articles each year.The statistical methods were reviewed in the aspects of statistical design,description,inference and expression.Results A total of 116 papers were collected.For the statistical design,99.1％ (115/116) used the control group and all were applied properly.The methods of randomization and blinding were used in 16.4％ (19/116) and 8.6％ (10/116) of papers,respectively,with 6 and 3 papers applied incorrectly.Statistical description was used in all papers with an accurate rate over 90.0％.The index for statistical description mainly included relative number,mean and standard deviation.The frequency for the usage of statistical tables was 45.7％ (53/116) and all were applied correctly.In 71.6％ (83/116) of papers,statistical inference methods were used,including t test,x2 test and analysis of variance.The overall incorrect rate was 29.7％ (27/91),with 27.8％ (5/18),25.5％ (12/47) and 24.0％ (6/25) for analysis of variance,t test and x2 test,respectively.The frequency for the usage of advanced statistical inference methods was 20.5％ (17/83) and all were applied correctly.For the statistical expression,98.0％ of papers provided the sample size and statistics.The incorrect rate of statistical expression was 60.3％ (70/116) and majority of the mistakes was the lack of basis for determining the sample size.Conclusions The overall correctness of statistical methods applied in the papers of CJNMMI was good,especially in statistical design,statistical description and advanced statistical inference methods.However,quality application skills need to be improved in areas such as methods of randomization,blinding,basic statistical inference and statistical expression.

Objective To evaluate the efficacy of jaw thrust device in the upper airway obstruction. Methods Thirty-five ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index < 30 kg/m~2 undergoing elective surgery under general anesthesia were included in this study. The anesthesia face mask was placed and held tightly by 4 straps of JTD and connected to the anesthesia machine. Anesthesia was induced with midazolam, propefol, fentanyl and atracurium. When muscle relaxation was achieved, tracheal intubation was not performed. The airway obstruction was assessed by airway peak pressure and stridor score (breathing sounds detected by auscultation over the trachea). And then tracheal intubation was performed, and the patients were mechanically ventilated. Results There was no significant difference in airway pressure and stridor scores between JTD and jaw thrust maneuver. Conclusion JTD can effectively lift the jaw and improve the upper airway obstruction.

In this paper,the teaching in medical microbiology experiment to the first group of foreign students in our college is analyzed and summarized,which will give us many experiences for later teachering.
