Objective To detect genetic alterations in pleomorphic xanthoastrocytoma (PXA), and to investigate the mechanism of development of this neoplasm. Methods Three patients with PXA were studied. Comparative genomic hybridization (CGH) was performed to study chromosomal imbalances in PXA. Using immunohistochemical analysis, the expression of EGFR was detected in PXA. Results Using CGH analysis, genetic imbalance was detected on at least one chromosome for each case. One patient revealed multiple genetic alterations, including gains of 2p14-pter, 4p15-pter, 7p21-qter, 11q24-qter, 12 and 15q14-qter,as well as losses of 8p11.2-pter, 9p11-p23, 10p12-pter, and 13q14-qter. This patient experienced tumor recurrence and died one year later. Gain on Chromosome 7 and loss on Chromosome 8p were demonstrated in 2 of the 3 patients. Immunohistochemically, no EGFR positive reaction was found in all cases. Conclusion Detection of genetic alterations is very important in understanding the pathogenesis of PXA.

Objective To investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P

AIM: To compare and analyze the stereopsis of intermittent exotropia children under the different backgrounds of dynamic stimuli and static stimuli.
METHODS: We collected 56 children ( male 26, female 30 with intermittent exotropia at the age from 5y to 12y and examined their stereopsis under the different backgrounds of dynamic stimuli and static stimuli using a multidimensional sense perception training software. The differences between the dynamic stereopsis and static stereopsis were compared.
RESULTS: Totally 17 cases ( 30%) had both dynamicstereopsis and static stereopsis, 39 cases ( 70%) had either dynamic or static stereopsis deficit, only 10 cases ( 26%) had dynamic stereopsis, 25 cases ( 64%) static stereopsis left and 4 cases ( 10%) were without any form of stereopsis. The positive rate of dynamic stereopsis was better than the positive rate of static stereopsis, with statistical significance (P<0. 05).
CONCLUSION: Dynamicstereopsis is better than the static stereopsis to intermittent exotropia children.

Objective: Maxillary and mandible fractures are severe intermaxillary injuries,frequently involving other vital organs,and usually difficult to be treated.This study discusses the treatment of maxillary and mandible fractures.Methods: We retrospectively analyzed the clinical data of 39 cases of maxillary fractures and/or mandible fractures.Results: Of the 39 cases,34 males,5 females and 84.64% aged from 20 to 50,87.17% were caused by vehicle accidents,and 94.87% were accompanied by injuries of other parts of the body.After surgical treatment,78.95% gained normal or basically normal ocular esthetic results and 68% achieved good or improved facial esthetic results.Conclusion: The results of treatment are closely related with the type and severity of fracture and the time and plan of treatment.Preoperative CT scanning and facial profile three-dimensional reconstruction are necessitated for a thorough evaluation of the fractures and an analysis of the causes and extent of facial and ocular changes.The best treatment plan for maxillary and/or mandible fractures would include anatomic reduction by surgery,intermaxillary elastic traction and rigid internal fixation with the Ti plate.

Thorough excavation and artful utilization of various kinds concrete and invisible learning resources contribute to the cultivation of excellent postgraduates.In postgraduate education of anesthesiology Xuzhou Medical College utilizes time,network,technique platform,research outcome,self-potentiality and clinical patients resources,which produces an active effect and has important instructional significance.

Objective To study the characteristics of event-related potentials P300 in patients with anxiety disorder(AD). Methods P300 tests were carried out in 30 patients with AD and 30 healthy adult controls. ResultsPatients with AD had significantly delayed P3 latency ([326?16] ms vs [339?19]ms, P

Objective To investigate the pathological features and differential diagnosis of mixed epithelial and stromal tumor of the kidney(MESTK). Methods Three patients with MESTK were studied by light microscopy and immunohistochemistry,and related literatures were reviewed. Results In the three patients,two were females and one was male,with the mean age of 20 years old.Examined grossly,the tumors were well circumscribed and typically composed of multiple cysts and solid areas.Microscopically,the tumors were composed of epithelial and spindle cells,both of the which were well differentiated with no atypia and mitosis of the nuclei.The immunohistochemical staining showed positive for the cytokeratin in the epithelial cells,and Vimentin,SMA,actin,PgR or ER and WT-1 in the spindle cells.No tumor recurrence and metastasis was found in all the three patients by 25 to 29 months of follow up. ConclusionMESTK is an uncommon mixed renal neoplasm with a favorable prognosis.

Objective To evaluate the effects of implementing the health education in the Central Fund Program to control endemic fluorosis in Guizhou.Methods The samples were randomly surveyed to evaluate knowledge awareness in students and households as well as the habit formation after implementing the integrated program which mainly consisted of installing the improved stoves,supported by the Central Funds and health education in 5 counties.Results After health education,the rates of knowledge awareness in the students and the households were 94.80%(15 562/16 415)and 88.23%(4482/5080),respectively,and increased significantly compared with those before intervention[44.20%(26 364/59 645),22.81%(3082/13 510)],the difference being significant(χ2=13 324.05,6546.24,P＜0.01).The rates of drying corn and chili with the coal fire were 5.61% (57/1016)and 5.41%(55/1016),respectively,and decreased significantly compared with those before intervention [77.41%(1076/1390),78.92%(1097/1390)],the difference being significant(χ2=1214.49,1270.92,P＜0.01).The rates of washing corn and chili were 99.51%(1011/1016)and 94.59%(961/1016),respectively,and increased significantly compared with those before intervention[84.60%(1176/1390),76.55%(1064/1390)],the difference being significant(χ2=154.80,143.32,P＜0.01).The rates of using the uncovered and unventilated iron stoves and table stoves were 4.71%(38/807)and 8.37%(60/717),respectively,and decreased significantly compared with those before intervention[29.99%(14 483/48 299),98.33%(95 070/96 685)],the difierence being significant(χ2=243.51,25 282.99,P＜0.01).Conclusions Implementing the health education is the basis for the integrated measures for controlling the endemic fluorosis in the endemic regions.The consciousness and activity of the target people have been enhanced greatly.The good behaviors in the target people are forming,the expected goal is reached.
