ObjectiveTo analyze the incidence,etiology and clinical treatment of the impacted maxillary central incisors.Methods A retrospective study was conducted on 29 cases of impacted maxillary central incisors that were randomly selected from the 1000 patients.Age of the patient was ranged from 7 to 23 years with median 11.1 years.Numbers of impacted teeth were 32,in which 22teeth were intraosseous impaction and others were extraosseous.The incidence,etiology,sites and direction of impacted teeth and their treatment approaches were explored in this study.Results Impac tion of maxillary central incisors occurred more frequently in females than in males,with a ratio of 1.0 ∶ 1.2.The ratio of intraosseous impaction to extraosseous one was 11 ∶ 5.The insufficient eruption space of maxillary central incisors was present in 65％ patients,but intermediate and severe crowded teeth only accounted for 15％.The incidence of the abnormal site and position of impacted teeth reached 71 ％.The clinical approach and solution were surgical-orthodontic treatment,transplantation or removal of impacted teeth.ConclusionsThe main cause is abnormity of teeth in the shape and position.Most of the impacted maxillary central incisors could be moved to the correct position by effective treatment.

Objective To evaluate the effectiveness of applying mind map in experiment teaching of fundamental nursing.Methods The mind map was applied in experiment teaching of fundamental nursing.the students in experimental group (n =36) was taught by mind map teaching method while those in control group (n =36) was taught by traditional method.The experimental group students' evaluation was collected during the experiment and operating examination was conducted for both groups.Results The students in experimental group were in favor of mind map,with each scores higher than three points.The operating examination score of experimental group (87.64 ± 4.23) was higher than that of control group (84.78 ± 4.42),with statistical differences (P =0.007).Conclusions Applying mind map in experiment teaching of fundamental nursing can improve teaching effect,cultivate students' ability of comprehensive analysis and arouse their interests.

Objective:To investigate the role of interleukin-10 (IL-10) and IL-12 in the differential diagnosis of tuberculous and malignant pleural effusion through measuring the serum and pleural effusion IL-10 and IL-12 levels of tuberculous and malignant pleural effusion patients.Methods: Forty-eight inpatients with exudative pleural effusion who didn''t receive any treatment before were selected.According to the pathogeny, the patients were divided into tuberculous pleural effusion group (n=25) and malignant pleural effusion group (n=23).The levels of IL-10 and IL-12 in peripheral blood and pleural effusion of the patients in two groups were detected by Cytometric Bead Array (CBA).The differences in IL-10, IL-12 levels and IL-12/IL-10 ratio were compared between two groups.The ROC curves of the above indexes, cast-off and adenosine deaminase (ADA) were used to compare the effects in differential diagnosis of tuberculous and malignant pleural effusion.Results: There were no statistical differences in the levels of serum IL-10, IL-12 and IL-12/IL-10 ratios of the patients between tuberculous and malignant pleural effusion groups (P>0.05),and the IL-12 level in pleural effusion and the IL-12/IL-10 ratio of the patients in malignant pleural effusion group were lower than those in tuberculous pleural effusion group (P<0.005).The area under the ROC curve for the levels of IL-12 in pleural effusion (0.984) was higher than those for the ratio of IL-12/IL-10, cast-off and ADA (0.744, 0.804 and 0.911, respectively) in the differential diagnosis of tuberculous and malignant pleural effusion.Conclusion: The detection of IL-12 levels in pleural effusion is helpful for the differential diagnosis of tuberculous and malignant pleural effusion, and the pleural effusion is easy to obtain, therefore the detection of IL-12 in pleural effusion is worth to be widely applied in clinic.

An adolescent patient,in the peak of growth and development,with severe skeletal Class Ⅲ malocclusion and maxillary impacted canines was treated by removable and fixed appliances in the upper and lower dental arches.After treatment,the crossbite was relieved,the facial contour was improved,the integrity of the denture was kept and the Class Ⅰ molar relationship was achieved.

In order to control the quality of all parts of the process for culturing,preparing and using clinically the human embryo olfactory ensheathing cells (OECs),the conduct standard of culturing human OECs from olfactory bulb is formulated. Because the strict conduct process can reduce the human factor as much as possible and ensure the stability of the cell quality. Therefore,during the culturing process of human embryo OECs, as for the embryo sample of OECs from olfactory bulb,the standard of lab condition and cell culture must be set strictly. The key steps of conduct process must be regulated,the freezing and resuscitating process of OECs must be controlled,the test method for microbial contamination during cell culture must be proposed and the risk must be reduced,then the quality of the human OECs from olfactory bulb can be guaranteed during the clinical application.

Objective To investigate the clinical significance and relationship of preS1, HBV DNA and HBV-M. Methods PreS1 and HBV-M was detected by ELISA method,and HBV DNA was detected by PCR. Then the results were analyzed. Results In HBV patients,the positive rates of preS1 and HBV DNA had no statistically significant ,they had fine dependability. The detection rate of preS1 in HBeAg(+) group(80.3%) and HBeAg(+)group( 56.3% ) had statistically significant. In some patients,though HBeAg had become negative, HBV still replicated. In HBV DNA replicated patients(≥103 copies/ml) ,the detection rate of HBeAg and preS1 were 51.5% and 70.9% ,they had statistically significant. Conclusion HBV DNA and PreS1 had fine dependability,preSl could reflect the replication of HBV sensitively than HBeAg,it could be used as a reliable new marker of HBV replication in vivo.
