Objective:To evaluate the relationship between MRI features and pathological types of intracranial meningomas.Methods:32 cases of meningoma which were proved by operation and pathology were compared with their MRI features and pathological types.Results:All of the 32 cases were single tumor,The lesions were located in frontal,parietal,and occipital regions nearby the convexity of the brain in 18 cases,at sphenoidal crest in 8 cases,at olfactory sulcus in 4 cases,and in sellar region 2 cases.MRI manifested that 13 cases had their intergral capsules,peri-tumor edema was found in 29 cases,dural“tail” sign was present in 9 cases,calcification in the tumors were found in 3 cases and vascular flow void features was seen in 5 cases,20 cases appeared homogeneous enhancement.Conclusion:It is of great value in presenting the location of meningoma with MRI.Combination of several MRI features could be used to figure out the pathological type of meningoma by a comprehensive analysis.

Objective To explore the anatomic characteristics of the bronchi,arteries,and veins of pulmonary segments on the coronal section.Methods Using serial coronal sections of thorax of 20 adult cadavers,multislice spiral CT images of 4 healthy volunteers,the segmental and subsegmental bronchi,arteries,and veins were traced and observed.Results There are 6 key sections for recognition of the segmental and subsegmental bronchovascular structures of the lungs on the coronal section:1.On the section through ascending aorta,the apical,lateral,apicoposterior,anterior,and superior lingular segmental veins appeared.2.On the section through pulmonary bifurcation,the left and right superior pulmonary veins can be seen under the pulmonary bifurcation.It appears on the coronal sections of 11 cadavers(55%) that apicoposterior segmental vein,anterior segmental vein,and lingular venous trunk drained into left superior pulmonary vein simultaneously.3.On the section through bifurcation of trachea,left and right superior lobar bronchi and their branches are demonstrated clearly.Under the bifurcation of trachea,it can be seen that left and right inferior pulmonary veins empty them into left atrium.4.On the section through intermediate bronchus,the origins of segmental bronchi,arteries,and veins of inferior lobes of bilateral lungs can be found.5.On the section through thoracic aorta,superior segmental and lateroposterior basal segmental bronchovasclature appeared mainly.6.On the section through spinal column,the inferior lobes of bilateral lungs shows the bronchi,arteries,and veins of superior,lateral basal,and posterior basal segments mainly.Conclusions The pulmonary segmental arteries and veins can be recognized exactly by tracing bronchi carefully on the coronal section.

Poly( ADP-ribose) polymerase 1 (PARP-1) plays an essential role in DNA repair and maintenance of homeostasis and genome stability. Increased PARP-1 activity has been reported in various forms of cancer. Thus the absence of PARP-1 or the use of its inhibitors depresses DNA repair function, sensitizes cancer cells to DNA damage and enhances the therapeutic effect of radio-or chemotherapy. PARP-1 is potentially a therapeutic target of malignant tumors.

Objective:To detect and analyze the mycoplasma infection in human laryngeal carcinoma and to explore the relationship between the infection with the development,progression and prognosis of laryngeal cancer.Methods: Immunohistochemical methods were employed to detect the mycoplasma infection in 214 specimens of different laryngeal lesions and cervical lymphatic tumors metastasized from laryngeal cancer,including 121 laryngeal cancer specimens,21 laryngeal precancerous specimens,17 vocal cord polypus specimens,14 normal laryngeal tissues adjacent to cancer tissues,9 normal laryngeal tissues opposite to the cancer,and 32 cervical lymphatic tumor specimens metastasized from laryngeal cancer.The infection results were subjected to statistical analysis.Results: The positive rates of mycoplasma 2G10 antibody in laryngeal carcinoma specimens,cervical lymphatic tumor specimens metastasized from laryngeal cancer,laryngeal precancerous specimens,vocal cord polypus specimens,normal laryngeal tissues adjacent to cancer tissues,and normal laryngeal tissues opposite to the cancer were 44.63%(54/121),34.38%(11/32),23.81%(5/21),17.65%(3/17),7.14%(1/14),and 0%(0/9),respectively,with those of laryngeal carcinoma specimens and cervical lymphatic tumor specimens metastasized from laryngeal cancer significantly higher than those of other specimens(P

Objective To write the school-based teaching material of pathology,and apply it to the students in higher vocational colleges to evaluate the application effect.Methods Two classes of clinical medical students of Grade 201 1were divided into two groups:the experimental group(Class1,58 students) and the control group(Class2,60 students).Both of the two groups take the integration of theory and practice teaching method.The traditional teaching material was applied in the control group while the school-based teaching materials were adopted in the experimental group.Statistical analysis software SPSS 13.0 and two samples t test were used to compare the preparing effect before the class,case study effect and the final examination of the two groups.After the end of the course,students' teaching satisfaction questionnaire was conducted,and the results of the survey for the rank sum test were analyzed.Results The scores of preparing effect before class were higher in experimental group(84.4 ±6.2) than those in the control group(78.2 ±5.8),t=5.61,P=0.001; the case study effect in experimental group(78.6 ± 6.6) was higher than that of the control group(72.8 ± 5.3),t=5.27,P=0.002; there was no significant differences in the final examination between the two class [experimental group (83.5 ± 6.8),control group (81.6 ± 6.9)],t=1.51,P=0.183.The questionnaire shows,in the aspect of the difficulty of teaching material,the degree of satisfaction in the experimental group(satisfied:28,general:30,unsatisfied:0) was higher than the control group(satisfied:18,general:37,unsatisfied:5),Z=-2.43,P=0.015; in the aspect of reading interest,the degree of satisfaction in the experimental group(satisfied:32,general:25,unsatisfied:1) was higher than the control group(satisfied:22,general:35,unsatisfied:3),Z=-2.09,P=0.036; in the aspect of emphasizing on the key point,the degree of satisfaction in the experimental group(satisfied:20,general:38,unsatisfied:0) was higher than the control group(satisfied:12,general:39,unsatisfied:9),Z=-2.72,P=0.007; in the aspect of self-study effect,the degree of satisfaction in the experimental group(satisfied:20,general:38,unsatisfied:0) was higher than the control group(satisfied:16,general:39,unsatisfied:5),Z=-3.13,P=0.002; but there was no significant differences in classroomlearning effect(experimental group:satisfied,38,general,20,unsatisfied,0; control group:satisfied,36,general,23,unsatisfied,1),Z=-0.68,P=0.497.Conclusions The school-based teaching material can contribute to the students' self-learning,enhancing the students' interest of learning and knowledge-application ability.

Objective To evaluate the clinical effect of integrated traditional Chinese and western medicine in treating chronic obstructive pulmonary disease (COPD). Methods 88 patients with COPD were randomly divided into a treatment group and a control group, with 44 patients in each group. The treatment group was treated with conventional western medical therapy plus traditional Chinese medical therapy, and the control group was treated with conventional western medical therapy exclusively. The clinical therapeutic effects were evaluated after 14 days of therapy. Results Symptoms of cough, phlegm, and asthma were improved in both groups. The total effective rate in the treatment group and the control group was 93.2% and 75.0% respectively. There was remarkable difference between the two groups (P＜0.05). Conclusion It is safe and effective for treating COPD with integrated traditional Chinese and western medicine.

With the change of clinical infection patterns,increasing number of multi-drug resistance bacteria and emerging of new discovering pathogens,the knowledge of Clinical Microbiology has developed and updated rapidly.It will produce positive effect on students'competence cultivation to introduce the knowledge about new techniques application and related subjects in student's clinical teaching practice.

The traditional Chinese medicine(TCM)has good results in treating asthma at remission stage,treating childhood bronchial asthma,and daily nursing.The western medicine usually takes the therapeutic methods of inhaling aerosol drugs,using anti-inflammatory drugs and undertaking interventional therapy,which have good results in relieve symptoms rapidly,dealing with emergent and severe onset of bronchial asthma and treating complications.The integration of these two medicines can cooperate with each other and exert good therapeufc effects.
