Objective To investigate the clinical characteristics on diagnosis and treatment of renal tubercu- losis.Methods Clinical data of 82 patients with renal tuberculosis were retrospectively reviewed.Results All of the 18 cases who received medication recovered completely.64 cases undergoing surgery were pathologically diagnosed to have renal tuberculosis,of which 2 cases developed ureteral stump syndrome.Conclusion Urine PCR-TB-DNA re- mained the primary diagnostic method before operation.Computed tomography(CT)and magnetic resonance urogra- phy(MRU)could be used in diagnosis of renal tuberculosis.When the non-functioning kidney was resected,per- inephrit fat and the involved ureter should be concomitantly resected as much as possible.

Objective To study the clinical characters and the prognosis of the sciatic nerve injury associated with acetabular fracture. Methods From January 1980 to January 2000, fourteen sciatic nerve injury resulted from acetabular fracture were observed. Three were treated with skeletal traction, eleven were treated with open reduction and internal fixation and neurolysis. Results All cases were followed-up for an average of 18 months. The anatomical reduction of acetabular fracture obtained in 57.1％ of the patients and satisfactory reduction in 42.9％ . The excellent and good nerve functional recovery was seen in 57.1％ according to MCRR. Conclusion Injury of the sciatic nerve associated with the acetabular fracture occurs most commonly when the hip is dislocated posteriorly. Injury of the common peroneal nerve, branching off from the sciatic nerve was more common and had poorer prognosis than that of the tibial nerve. Flexion of the knee and extension of the hip during the surgical reduction of acetabular fracture can reduce iatrogenic injury of the sciatic nerve. Early reduction of acetabular fracture and neurolysis is important for the recovery of function of the sciatic never.

Objective To investigate the expression and signification of B-cell lymphoma/leukemia-2(bcl-2),bax and ER proteins in epithelial cells in different depth of adenomyosis.Methods Expression and correlation of bcl-2,bax and ER proteins were detected by immunohistochemistry staining in 36 adenomyosis cases with superficial (＜ 1/2 depth of penetration) and deep (≥ 1/2 depth of penetration)ectopic endometrium and eutopic endometrial tissues matched with 30 cases with benign ovarian tumor,uterine septum,pelvic floor dysfunction without adenomyosis as controls.Results (1) The expression of ER protein in superficial and deep ectopic tissues (5.04 ±0.24,4.91 ±0.16) were found significantly lower than 6.06 ± 0.36 in eutopic tissues (P ＜ 0.01) and higher than 3.70 ± 0.58 in control group (P ＜ 0.05).There was no statistical difference of ER expression in superficial and deep ectopic endometrium (P ＞ 0.05).(2) The level of bcl-2 protein of 5.6 ± 0.4 in superficial and 6.0 ± 0.3 in deep myometrium of ectopic tissues were significantly higher than 3.6 ± 0.4 in eutopic tissues and 1.9 ± 0.4 in control group (P ＜ 0.01).(3) The level of bax protein of 3.50 ± 0.28 in superficial and 4.80 ± 0.29 in deep myometrial ectopic and 4.43 ± 0.37 in eutopic tissues were significantly lower than 6.18 ± 0.65 in control groups (P ＜0.05).The expression of bax in superficial myometrium is significantly lower than deep myometrium in ectopic tissues (P ＜0.01).(4) The positive correlation between the expression of ER and bcl-2 protein at superficial myometrium of ectopic tissues (r =0.720,P ＜ 0.01).And there was no significant correlation with the expression of ER and bax protein at superficial myometrium (r =0.008,P ＞ 0.05).As well as,there was not significant correlation with the expression of bcl-2,bax and ER protein at deep myometrium (r =0.089,r =-0.023,P ＞ 0.05).The expression of bax protein in ectopic endometrium was positive correlation with the depth of adenomyosis penetration (r =0.736,P ＜ 0.01).There was positive correlation between the expression of ER and bcl-2 protein at normal endometrium (r =0.453,P ＜ 0.05).And there was negative correlation between the expression of ER and bax protein at control group (r =-0.514,P =0.05).Conclusion The bax protein expression of ectopic endometrium in deep adenomyosis was higher than superficial adenomyosis.

Objective Using 7.0 T diffusion tensor imaging(DTI) to study myocardial fibers character in isolated rats heart in aspect of water molecular diffusion, myocardial mechanics and microstructure. Methods Fixed male rats heart (n=10) underwent DTI and the myocardial structures were quantitatively measured by Diffusion Toolkit and Matlab. The characteristic of myocardial fibers arrangement was observed and FA values and ADC values of myocardial fibers, myocardial fibers density and length, mean helix angle of left ventricular were calculated as well. Mean helix angle of anterior wall, ventricular septum, lateral wall and posterior wall of epicardium and endocardium were compared by using one?way ANOVA. Results The SD rats' myocardial fibers appeared in compact and inerratic distribution from epicardium to endocardium. Compared with HE staining, regular direction and arrangement in fibers were showed in myocardial fibers tracer map and tensor map in papillary muscle plane. Quantitative analysis showed that ADC value of SD rats' myocardial fibers was (9.6 ± 3.6) × 10-4 mm2/s, FA value was 0.80 ± 0.04, myocardial fibers density was (981±24) tracks/mm3 and myocardial fibers length was (6.18±1.71)mm. Mean helix angle of left ventricular epicardium to endocardium ranged from-81.37° to 0° and then gradually change to 82.83° . There were no significant differences in mean helix angle of anterior wall, ventricular septum, lateral wall and posterior wall of epicardium and endocardium, respectively (F=2.25, 0.40, P>0.05). Conclusions This study shows that DTI is an effective method to quantitatively measure the characteristics of myocardial fibers. This study provides useful information for further study of myocardial fibers in heart disease models.

Objective To study the changes of resistin and the relationship between resistin and other indexes in patients with type 2 diabetes mellitus. Methods Seventy patients with type 2 diabetics were chosen and divided into three groups according to weight index and 15 healthy persons were chosen as controls. ELISA was adopted to determine resistin concentration. Oxydase method was adopted to measure blood sugar. Radio immunoassay was used to measure insulin level. Results Resistin concentration of patient groups r(23.06±9.34)μg/L ] was significantly higher than that of control group [( 9. 89±4. 47) μg/L, P<0. 01 ]. Resistin was positively related to body mass index (r = 0.4 467) and fat distribution (r= 0. 3 314, P<0.01). Resistin was also positively correlated to the area under the curve of sugar tolerance (r=0. 7 063, P<0. 01), negatively related to the insulin resistance index (r=-0. 4 154, P<0.01), but not related to area under the curve of synchronous insulin release (P>0. 05). And a formula was obtainted : Resistin=- 15. 869 + 0. 339×GAUC+0.790×BMI. Conclusion The level of reslstin in type 2 diabetics is higher. And reslstin is related to other factors. This formula is of great significance for clinical study of diabetic's disor- ders.

BACKGROUND: Color Doppler flow imaging can exam the early myocardial disorder in type 2 diabetic patients. What does exercise tolerance test work for the examination of such disorder in combination with color Doppler flow imaging (CDFI) ?OBJECTIVE: To analyze in comparison the early evaluation on reduced diastolic function in left ventricle in patients with type 2 diabetes between the examinations of exercise tolerance test combined with color Doppler flow image and simple color Doppler flow imaging.DESIGN: Cases-controlled comparison and self-comparison.SETTING: Department of electrodiagnosis and department of Endocrinology in a municipal hospital.PARTICIPANTS: Thirty-six cases of inpatients with type 2 diabetes were selected from Department of Endocrinology of Shenyang Red Cross Hospital from March to December in 2004, of which, 25 cases were males and 11cases females. The diabetic patients included had no cardiac vascular complications and participated in the study in volunteer. Thirty-two patients who received annual routine health check at the same period were selected as the control, of which, 20 cases were males and 12 cases females.METHODS: Metronics treadmill exercise test equipment was used for exercise tolerance in two groups. Before exercise(at quiescent state) and after exercise tolerance, Vivid 4 CDFI was used to determine flow velocity at E and A peak values respectively, ratio between flow velocities at E peak value and A peak value as well as isovolumtric relaxation time (IRT).MAIN OUTCOME MEASURES: Comparison of cardiac functional indexes before and after exercise tolerance in two groups.RESULTS: Thirty-four diabetic patients accomplished exercise tolerance test, of which, 1 case presented frequent ventricular extrasystole, another one presented precordial pain and stopped the test. In the control, all of 32 cases ratio between flow rates of E peak value and A peak value was remarkably lower than that in the control (0. 90 ± 0. 25, 1.40 ± 0.30, P ＜ 0.05 ); IRT was remarkably longer than that in the control [ (112. 07 ± 20. 16),imental group, the ratio between flow rates of E peak value and A peak value was remarkably lower than that in the control (0.62 ±0. 12, 1.28 ±0.87, P＜ 0.01 ); IRT was remarkably longer than that in the control[ (138. 10± 19.21), (97.37±9.61) ms, P ＜0.01].CONCLUSION: CDFI can supervise and evaluate at early stage the cardiac functional changes in type 2 diabetic patients. Due to the induction of exercise tolerance, the combination of exercise tolerance test and CDFI provides more accurate, objective and valuable conclusions at early stage.
