Objective To analyse the MRI characteristics of the chronic clicking temporomandibular joints(TMJs).Methods 20 TMJs in 10 young chronic clicking individuals (12 clicking TMJs)and 60 TMJs in 30 young healthy volunteers were examined by MRI scanner, and sagittal oblique opened-mouth and closed-mouth position images were observed.Then comparing the MRI findings of the acquired j oints between two groups.Results The ratio of the non-double concave articular disc,slightly high signal intensity in the articular disc, abnormal changes of the condyle,articular fluid,anterior displacement of the articular disc,and increasedDraceangles in the clicking group were significantly higher than those in the control group(P<0.05).The result revealed statistically significant differences.Conclusion The MRI anatomical characteristics can be an indicator for the TMJ anomalys,and provide an obj ective radiological basis for clinical diagnosis and treatment to some extent.

Objective To improve the method for the Word-Stock file update and cancel the Disk P mapping in order to meet the requirements of HIS such as Out-Patient Doctor Workstation system and Nurse system.Methods Two tables were created to store the names,contents and update time of the dictionary,and the word-stock file was built through searching the data of the tables.Results The word-stock file update was improved successfully.Conclusion The new method for the word-stock file update is easy to be achieved so that the program of client can update immediately,which also can get rid of the error and hidden troubles.

Purpose: To evaluate the efficacy and adverse effects of letrozole for postmenopausal breast cancer patients with bone raetastases. Methods: Thity-six breast cancer patients with bone metstases received 2. 5 mg tablet letrozole every day. for at least two months. Results: In the 36 patients who were evaluable for efficacy and toxicity, the complete response rate (CR) , partial response rate ( PR) , disease stabilization rate ( SD) and progressive disease rate ( PD) were respectively 5.5% , 22. 2% , 55. 5% and 16. 6% . The clinical benefit rate ( CR + PR + SD ≥ 6 months ) was 58. 3% (21/36) with 11 patients (30. 5%) having SD for at least 6 months . Conclusions: Letrozole is a well tolerated agent with reasonable efficacy but low toxicity for postmenopausal breast cancer patients with bone metastases.

Objective To investigate the association between brain structure abnormalities and neuropsychology impairment in CAD patients.Methods Nineteen patients with CAD and 1 7 healthy adults were examed with MRI,and T1 WI,T2 WI,FLAIR,DWI and DKI image were performed,and then comparing the acquired MRI findings between two groups.Results Significant differences were observed for MK values in splenium and body of the corpus callosum,left cerebellar hemisphere and amygdala cerebelli.MK values of CAD group were lower than those of healthy group in these regions,and differences were statistically significant(P <0.05). There were significant correlation between MK values of the left amygdala cerebelli and MoCA scores in CAD group.Conclusion DKI could detect the changes of brain tissue microstructure in CAD patients early.The correlation between MK and neuropsychologi-cal function provides an important basis for early diagnosis and treatment.

0.05). Conclusion It appears that early fixation of long bone fractures with intramedullary nail has little influence on pulmonary blood dynamics.

Objective To analyze the death causes of cadaveric kidney transplantation recipients. Methods The clinical data of 1400 cases of cadaveric kidney tansplantation between 1978 and 2003 were analyzed retrospectivvely. The death rate, causes and period were analyzed among the died recipients after kidney transplantation. Results 187 patients were died after renal transplantation in this stage with the ratio being 13.36% (187/1400). The death causes contained infection, cardiocerebra l vascular diseases and hepatic failure by turns, and the ratio was 37.97% , 31.56% and 14.97% , respectively. There were 87 ( 46.5% ) death cases w ith normal transplanted-kidney function. Conclusions The leading causes of patients' death were infection, cardiocerebral vascular d iseases, and hepatic failure. About half of these patients were died with normal transplanted-kidney function.

Objective: To develop a Chinese version of the Schedule for the Deficit Syndrome(SDS) and examine its reliability and validity. Methods: 123 schizophrenic patients finished the Chinese version of SDS and were subtyped into deficit (n=30) and nondeficit(n=93) groups. In addition, all patients completed BPRS, SANS and SAPS. The reliability analysis of SDS included Cronbach's ?琢 coefficients and mean inter-item correlations and the inter-rater reliability; while the validity analysis included construct validity and criteria validity. Results: The Cronbach's ?琢 coefficient and the mean interitem correlation coefficients of the negative symptoms severity subscale of SDS were 0.8441 and 0.4818, respectively. The inter-rater reliability for categorization was 0.8777. The correlation coefficients of the six negative symptom items with the total score ranged from 0.685 to 0.875,and that among the six negative symptom items ranged from 0.437 to 0.794. The negative symptom items and the total score of SDS were significantly correlated with the anergia factor score from the BPRS and the total score and several subscale scores of SANS, while none of them was correlated with subscale scores and total score of SAPS. Conclusion: The Chinese version of SDS was a reliable and valid measure for the diagnostic classification of deficit and nondeficit schizophrenia.
