Objective To observe the effects of rehabilitation in the 55 prelingually deaf pediatric cases for two years after cochlear implantation ,factors including cochlear implantation and recovery time ;to compare the re-covery effects in the group of 1 to 3 years old children with the group of 3~5 years old (including the age of 3 years old) who lost their hearing before learning to speak ,and to provide clinical evidence for providing cochlear implant therapy to the prelingually deaf children as early as possible .Methods A total of 55 pediatric relingually deaf cases were included in this study .According to their implantation time and application duration ,they were divided into 2 groups :1 to 3 years old group (32 cases) ,and >3 to 5 years old group (23 cases) respectively .The hearing ,lan-guage and learning abilities on 1 ,3 ,6 ,12 ,18 ,24 months after cochlear implantation were evaluated ,using statisti-cal method to record CAP and SIR scores .Results The rehabilitation effects ,the average ages ,CAP ,speech rec-ognition rates and SIR were increased two years afterwards .The effects of younger age group were more noticeable than that in the older group .The differences between the two groups were statistically significant (P<0 .05) .Av-erage speech recognition rates ,average speech rehabilitation effects in each postoperative period of younger age group were better than those of in older age group ,showing significant differences (P<0 .05);CAPs in the younger age group on 1 ,3 and 12 months after CI surgery were significantly higher than those of in the older group (P value were 0 .001 ,0 .001 and 0 .002 ,respectively) .SIR in the younger age group at the time of 1 ,3 ,12 ,24 months were significantly higher than those of in the older group(P values were 0 .00 ,0 .00 ,0 .00 and 0 .024 ,respectively) . Conclusion Implanted age and recovery time are the key factors that influence the effects of postoperative rehabilita-tion .The younger when the children get cochlear implantation and the longer the recovery time takes during two years after cochlear implantation ,the better the results are .The standardization of domestic assessment for the re-covery effects and the international evaluation method have a certain degree of equivalence .

Aim Toinvestigatetheinducementeffect of isatin on apoptosis of breast cancer cell line MCF-7 , andexploreitsdetailedmechanism.Methods MCF-7 cell lines were exposed to isatin at different concentra-tions(0,50,100,200 μmol·L-1 )for 48 h.Apop-totic features were demonstrated by nuclei staining with Hoechst 33258.Bcl-2,Bax and p53 mRNA were ana-lyzed by RT-PCR.Caspase-9 activation and mitochon-drial depolarization were assayed by flow cytometry. Bcl-2,Bax,p53 and cytochrome c proteins were ana-lyzedbyWesternblot.Results Isatininducesapopto-sis of MCF-7 cells.Furthermore,Bcl-2 expression was decreased and the ratio of Bcl-2 to Bax was significant-ly decreased by isatin.While,p53 expression relative-ly decreased.The mitochondrial transmembrane poten-tial was markedly reduced and the release of cyto-chrome c into the cytosol was increased after treatment with isatin.Simultaneously,caspase-9 was activated. Conclusions Isatinsignificantlyinducedtheapopto-sis of MCF-7 cells in vitro.These results strongly sug-gest that the p53 dependent mitochondrial pathway is involved in apoptosis.

Objective: To examine the effects of the education with glycemic index(GI)on dietary knowledge,attitude and practice of diabetic patients,and on their blood glucose and lipid.Methods: Seventy-two subjects with type 2 diabetes were randomly assingned into two groups. The test group (group GI) mainly learned the knowledge about GI of food. The controlled group (group FEL) mainly learned the knowledge about food exchange list(FEL). Outcomes were assessed by the change of dietary knowledge, attitude and practice, fasting blood glucose (FBG), 2 h postprandial blood glucose ( 2 hPBG), glycosylated hemoglobin (HbA 1c), and blood lipids which include total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG) and lipid comprehensive index (LCI). The period lasted five months. Results: The percent of correct answer for GI questions was increased significantly from 0 % before education to 92.2% after education (P

In teaching of Microbiology, we introduced microbiological history and research experiences of scientists. Students had more interesting in learning and got some ideas of science research. Eighty percent of them got good points.

Objective To discuss the image features of different types of pneumonia. Methods The method and flow for CR chest radiography at fever clinics were described. Results The method and flow for CR chest radiography at fever clinics were improved. Conclusion Method improvement is very significant.

Objective:To investigate the mRNA expression of the WIF-1 gene and the methylation of its promoter in breast can-cer, and to determine the correlation between the epigenetic aberrant WIF-1 DNA methylation and the clinicopathological significance of WIF-1 in breast cancer . Methods:RT-PCR and sensitive methylation-specific-PCR (MSP) were used to detect WIF-1 mRNA ex-pression and the methylation of the WIF-1 promoter in 30 breast cancer samples as well as in tumor-adjacent tissue samples and 9 be-nign breast tissues. Results:The WIF-1 mRNA expression in 30 breast cancer samples significantly decreased compared with those of the other two groups. In addition, WIF-1 methylation was more frequent in breast-tumor tissues compared with those in tumor-free tis-sues. Meanwhile, WIF-1 mRNA expression in breast cancer tissues involved the abnormal methylation of its promoter. Clinicopatholog-ical correlation analysis showed that the abnormal methylation of the WIF-1 gene promoter was not associated with age, TNM stage, histotype, or lymph node metastasis. Conclusion:WIF-1 mRNA expression loss due to abnormal methylation may be a crucial factor in breast cancer development and can thus be used in the prognosis and progression of the disease.

Objective To evaluate the effect of online teaching platform in clinical neurology prac-tice. Methods The participants were medical undergraduate students in the process of clinical practice in Department of Neurology of XiJing hospital, who were divided into the traditional practice teaching group (n=77) and online platform auxiliary practice teaching group (n=90), respectively carry-ing out the corre-sponding rotation practice teaching . Unified objective structured clinical examination was given to two groups of students to implement departmental rotation examination , and investigation was made among teachers and students on the evaluation of the effect of practice. SPSS 19.0 was used to do t test to the two sets of corresponding evaluation data. Results Total score of departmental rotation examination in online platform auxiliary practice teaching group (69.33 ±2.74) was significantly higher than traditional teaching group (67.23±2.50) (P=0.000). Scores of basic theories, skill and operation, clinical case analysis in online platform auxiliary practice teaching group were significantly higher than traditional teaching group (P<0.05). However, medical record writing scores in online platform auxiliary practice teaching group (7.39± 1.09) were significantly lower than the traditional teaching group (8.03±1.03) (P=0.000). Teachers' eval-uation of practice effect was obviously higher in online platform auxiliary practice teaching group (12.33± 0.52) than that in traditional teaching group (10.67 ±1.03) (P=0.005). Students' evaluation of interest in learning, content arrangement, teachers' sense of responsibility, evaluation of teaching ability, practice effect were obviously higher than that of traditional teaching group (P<0.05). Conclusion This study preliminary has achieved good practical effect by using online auxiliary teaching platform, and got high evaluation by both teachers and students. Inter-active communication and sharing of resources is easy in the online plat-form of practice teaching . On-line platform will help students develop with clinical neurology diagnosis thinking.
