Objective To investigate the echocardiographic determination of uremic patients with myocardial weight and in the evaluation of cardiac function in patients with uremia heart the significance of the damage.Methods 70 cases of uremic patients and 30 normal physical were examined by routine echocardiography,cardiac measurements through the menu of uremic patients with myocardial weight and heart function.The patient group and the normal control group were compared.Results 70 patients with uremic echocardiography resuits of the analysis showed,respectively,12.8%and 84.3%existence of left ventricular systolic dysfunction and left ventricular diastolic dysfunction.left ventricular mass in patients with significant increase are significantly higher than those in healthy control group(P＜0.01).Conclusion Uremic patients left ventricular diastolic dysfunction and left ventricular hypertrophy most of echocardiography is the detection of cardiac damage in patients with uremia practical,sensitive,non-invasive examination will be able to clinical diagnosis and treatment provide guidance in the clinical widely used.

Objective To study the clinical valne of color Doppler ultrasound for the diagnosis of primary ureteral carcinoma. Methods 15 patients with pathologically confirmed primary ureteral carcinoma by color Doppler ultrasound were retrospectively analyzed. Results 15 patients with lesions above the ureter and renal pelvis and varying degrees of expansion,water, of which 11 cases of solid mass within the probe and ureter. Color Doppler showed lesions could be detected, and dot, stripe and dendritic arterial blood flow signal, resistance index (RI) 0. 58 ～ 0. 67.Conclusion Color Doppler ultrasound screening of primary ureteral carcinoma has important diagnostic value, can increase the rate of preoperative diagnosis,and can provide reference for clinical staging.

Objective To explore the clinical manifestations, electroencephalographic characteristics and therapeutic effect of drugs in children with Jeavons syndrome. Methods The clinical and electroencephalographic characteristics and thera-peutic effect of drugs were analyzed in 4 children with Jeavons syndrome. Results Among the four children there were 3 female and 1 male. The age at the onset of the disease was from 1 to 6 years. The typical clinical manifestations of this disease were brief, fast and repeated eyelid myoclonia (EM) with or without absence seizure. The typical electroencephalography (EEG) in two patients showed 3-6 Hz generalized spike and waves and polyspikes burst, and the eye closure and intermittent photic stimu-lation helped to induce discharges and clinical events. The typictal EEG in the other two patients showed 3.0-3.5 Hz generalizedδslow wave rhythm burst. The drugs of choice for treatment was sodium valproate monotherapy in two cases, levetiracetam in one case, sodium valproate combined with levetiracetam in one case. During the follow-up, seizures were controlled in one case, decreased in frequency in two cases and were still frequent in one case. Conclusions Jeavons syndrome is one of the idiopathic and generalized epileptic syndromes and characterized by EM with or without absence seizure. Video EEG monitoring plays an important role in the diagnosis of this disease. Sodium valproate and levetiracetam were effective for this disease.

BACKGROUND:Bisphosphonates that can suppress osteoclast activity strongly is a powerful inhibitor for bone resorption, which has been reported to have good effects in the treatment of fibrous dysplasia.
OBJECTIVE:To evaluate the clinical effect of surgical treatment combined with bisphosphonate therapy in the treatment of fibrous dysplasia.
METHODS: Fifteen patients with fibrous dysplasia of the long bone were subjected to surgical treatment and oral bisphosphonate therapy postoperatively. Limb pain, limb function, local X-ray manifestations and blood alkaline phosphatase activity were observed before and at 3, 6, 12, 24 months after treatment. The therapeutic effects were evaluated using modified Macnab standards.
RESULTS AND CONCLUSION:Al the 15 patients were folowed up for more than 24 months, and their pain symptoms were significantly relieved after the combined treatment of surgery and bisphosphonates, excelent in 12 cases and effective in 1 case, and the total efficiency was 100%. X-ray films showed that the density slightly decreased in operation areas after 3 months, but at 6 months after treatment, the cortical bone was thickened and the marrow cavity density increased in the operation areas, and non-focal zone was continuously enlarged. No fractures and recurrence were found in al patients. At 6 months after treatment, the serum alkaline phosphatase activity decreased significantly (P < 0.05). The results suggest that surgical operation with bisphosphonate treatment for bone fibrous dysplasia can effectively inhibit the bone resorption, promote bone formation, increase the intensity of the lesion, reduce fractures and recurrence rate, so as to achieve a better therapeutic effect in clinic.

Objective: To evaluate the diagnostic value of fluorine-18 fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography ( PET/CT) in fever of unknown origin ( FUO) in a Chinese hospital .Methods:The records of 51 patients with FUO (32 men and 19 women;mean age 54 years with a range between 3 and 81 years) were analyzed retrospectively .All the patients were examined by 18 F-FDG PET/CT scan and the results were compared with the final diagnosis which was established by additional procedures including pathology , laboratory examination , and clinical follow-up for more than 3 months.The t test was used for statistical analysis .Results: A final diagnosis was established for 48 patients , including 32 patients with infectious diseases , 9 with malignancies , and 7 with non-infectious inflammatory diseases .By FDG PET scan alone , the rates of true positive , false positive , false negative, and true negative were 52.9%, 27.5%, 17.6%, and 2.0%, respectively.By FDG PET/CT scan, the rates of true positive, false positive, false negative, and true negative were 70.6%, 27.5%, 2.0%, and 0, respectively.18F-PET/CT had a sensitivity of 97.3%(36/37), specificity of 0 (0/14), and accuracy of 70.6%(36/51) in FUO, especially a high sensitivity and accuracy of 100%(9/9) in the diagnosis of malignant tumor .Moreover , the maximum standardized uptake value ( SUVmax ) in tumor was significant higher than that in infection (3.7 ±2.7 vs.7.7 ±3.5, P=0.001, t=3.6), which implied that SUVmax might be useful in differential diagnosis in FUO .Conclusion:FDG PET/CT is a valuable imaging tool for the identification and location of the potential lesion in FUO and is helpful for the etiological diagnosis , especially in the diagnosis of malignant lesions .
