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 physical and mechanical properties of home-made bone cement mixed with different antibiotics.Methods The specimens of bone cement each of 40g were divid-ed in to6groups depending on mixed antibiotics,groupⅠmixed with1g gentamicin,groupⅡwith2g gen tam icin,groupⅢwith1g cephradine,groupⅣwith1.5g cefuroxine,groupⅤwith1g ceftriaxone and groupⅥwith out any antibiotics served as control.The dough time,compressing depth,compressive strength,bending strength and bending elastic modulus were measured respectively,elution examination of antibiotics from bone ce ment was performed by chromatography.Results The dough time and compress-ing depth of the groups were better than that of ISO5833standard,and there was no significant difference a-mong the groups.The com pressive strength and bending strength of the groupⅡwere lower than that ISO5833standard,but there was no significant difference among the groups by analysis of variance.The bending elastic modulus of the groupⅡwas lower than the control group and other groups(P

Nowadays more and more attention has been paid to the problems about housing and health in China. Some investigations showed that people spent almost fourteen hours in their homes every day so the houses become the major places of daily activities. It is very important to solve the problems of what is the relation between the housing and health and how the housing influences the health of the people living in it. In the present paper the author summarized the overseas and domestic researches on the housing and health and pointed out that the research on housing and health in China is just in the preliminary phase.

Objective To evaluate the surgical results of off-pump for plication for left ventricular aneurysm. Methods The study included 34 patients with left ventricular aneurysm,who underwent left ventricular aneurysmecto- my and plicatien on pump in group Ⅰ(17 cases)and simply aneurysm plicatien off pump in group Ⅱ(17 cases).All patients except two in group I underwent coronary artery bypass grafting simultaneously.Results There was one early death in group Ⅱ because of refractory ventricular arrhythmia.The complication included atrial fibrillation,ventricular arrhythmias,heart failure and delayed healing of wound.The aneurysm in group Ⅰ[(45?15)%of the ventricle]is larger than in groupⅡ[(29?12)%of the ventricle,P

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.

Objective To explore the nutrition condition improvement function of Jianpihuazhuoshengxue mixture to the long-term maintenance hemodialysis patient. Methods Before the treatment, to determine the nutrition condition of 43 cases dialysis patient that are divided to treatment group and control group. The two groups are all dialyze, the treatment group are added of Jianpihuazhuoshengxue mixture. To measure nutrition condition of the two groups again after one treatment course. Results and Conclusion Jianpihuazhuoshengxue mixture can remarkably raise the dialysis patient's nutritional level, especially the plasma albumin level. Possibly the mixture improvement the nutrition condition of dialysis patient mainly through raising the plasma albumin level, thus improve quality of life of the dialysis patient.
