Objective To sum up the experience of renal transplantation in order to improve transplant effect and enhance the long-term survival and recovery rate.Methods The data of renal transplantation of 1 124 cases who received renal transplantation from Jul. 1978 to Oct. 2001 were summarized. All the possible factors that could influence the transplant effect such as pre-operative preparation, HLA match, donors' quality, surgical procedure, immunosuppressive therapy and so on were analyzed. Results The 1-, 3-, 5-year survival rate (%) of patient/kidney was 83.1/ 70.3, 74.6/ 68.6 and 62.6/ 56.1 respectively. The rate of AR was decreased significantly from 3.09?% only with LXM to 0.89?% with LXM test in combination with HLA serological test. The rate of HAR and AR in 130 cases with additional PRA test were lower than those only with LXM test.Conclusions The well pre-operative preparation, the ideal HLA match, the high quality of donor's kidney and transplant operation were keys for successful renal transplantation. Reduction of the complications, individual and combined medication in reason and long-term follow-up were very important in the long-term survival time.

Objective To investigate the causes of misdiagnosis of B-ultrasonography in thyroid nodule and the function of B-ultrasonography in diagnosis in thyroid nodule.Methods 307 patients with thyroid nodule were analysis between the diagnosis of B-ultrasonography and pathology.Results The diagnosis of B-ultrasonography was different from the diagnosis of pathology in thyroid nodule. If the thyroid nodule found by B-ultrasonography was multiple, it was nodular goiter; If the thyroid nodule found by B-ultrasonography was single, the ratio of nodular goiter and thyroid adenoma was 3∶2.Conclusions Clinical physician did not grant the diagnosis of B-ultrasonagraphy as clinical diagnosis. Most of multiple thyroid nodules were nodular goiter, single mass may be nodular goiter or thyroid adenoma. When the diagnosis of B-ultrasonagraphy was thyroid occupation, it may be malignant thyroid neoplasm.

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 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 computer-aided diagnosis(CAD)system with automatic contouring and morphologic and tex-tural analysis to aid on the classification of breast nodules on ultrasound images .Methods A modified Level Set method was pro-posed to automatically segment the breast nodules(46 malignant and 60 benign nodules) .Following ,16 morphologic features and 17 texture features from the extracted contour were calculated and principal component analysis(PCA)was applied to find the optimal feature vector dimensions .Fuzzy C-means classifier was utilized to identify the breast nodule as benign or malignant with selected principal vectors .Results The performance of morphologic features was 78 .30% for accuracy ,67 .39% for sensitivity and 86 .67%for specificity ,while the latter was 72 .64% ,58 .70% and 83 .33% ,respectively .After the combination of the two features ,the re-sult was exactly the same with the morphologic performance .Conclusion This system performs well in classifying the malignant breast nodule from the benign breast nodule .
