The chemiluminescence reaction of amidopyrine-potassium permanganate with formaldehyde as an enhancer was investigated by flow injection system. A method for the determination of amidopyrine on the basis of this technique was proposed. The detection limit is 3.0×10－8 g/mL, the relative standard deviation is 1.3% (4.0×10－6 g/mL amidopyrine,n=11).The linear range is 1.0×10－7～8.0×10－5g/mL amidopyrine.　The method has been applied to the determination of amidopyrine in the antondin injection.

Objective:To optimize 3.0T MRI diagnosis indicator in breast cancer and to select the best MRI scan program.
Methods:Totally 45 patients with breast cancers were collected, and another 35 patients with benign breast tumor served as the control group. All patients underwent 3.0T MRI, including T1-weighted imaging (T1WI), fat suppression of the T2-weighted imaging (T2WI), diffusion weighted imaging (DWI), 1H magnetic resonance spectroscopy (1H-MRS) and dynamic contrast enhanced (DCE) sequence. With operation pathology results as the gold standard in the diagnosis of breast diseases, the pathological results of benign and malignant served as dependent variables, and the diagnostic indicators of MRI were taken as independent variables. We put all the indicators of MRI examination under Logistic regression analysis, established the Logistic model, and optimized the diagnosis indicators of MRI examination to further improve MRI scan of breast cancer.
Results:By Logistic regression analysis, some indicators were selected in the equation, including the edge feature of the tumor, the time-signal intensity curve (TIC) type and the apparent diffusion coeffcient (ADC) value when b=500 s/mm2. hTe regression equation was Logit (P)=-21.936+20.478X6+3.267X7+21.488X3.
Conclusion:Valuable indicators in the diagnosis of breast cancer are the edge feature of the tumor, the TIC type and the ADC value when b=500 s/mm2. Combining conventional MRI scan, DWI and dynamic enhanced MRI is a better examination program, while MRS is the complementary program when diagnosis is diffcult.

Objective To evaluate the value of MSCT perfusion imaging in assessment of single renal function of hydronephrotic kidney.Methods 64-slice spiral CT perfusion was performed in 36 obstructive nephrohydrosis patients whose split renal glomerular filtration rate(GFR) was measured by SPECT renal dynamic imaging. ①The perfusion parameters of the renal cortex and renal medulla of the hydronephrotic kidney were compared with the normal kidney studied by contrast group. ②The 72 kidneys were divided into normal renal function, mild and severe renal impairment groups according to renal function. Differences between the groups respect to all the mean perfusion parameters of the renal cortex and renal medulla were assesses by ANOVA. ③Using Pearsons correlation test, the correlations between all the mean perfusion parameters of the renal cortex and renal medulla and renal GFR were examined.Results ① The time-density curves of bilateral normal renal cortex and medulla were not symmetric. The mean BF, BV, PS, PBV of renal cortex were (203. 2±44.9)ml·100 ml~(-1)·min~(-1), (27.6±3.9)ml/100 ml, (30.7±6.5)ml·100 ml~(-1)· min~(-1), (46.5±10. 9)ml/100 ml; and the mean BF, BV, PS, PBV of renal medulla were (99.9±24.1)ml·100 ml~(-1)·min~(-1) ,(18. 3±4.3)ml/100 ml, (51.8±12.1)ml · 100 ml~(-1)· min~(-1) , (21.3±3.0)ml/100 ml. The mean perfusion parameters of the cortex and medulla of obstructed kidney were lower compared to that of normal kidney. ②There were significant differences of all the perfusion parameters of the renal cortex and me-dulla between 3 groups (P<0. 05). ③The perfusion parameters of the renal cortex and medulla had positive linear correlation with GFR. The best correlation was the blood flow of the cortex of kidney. The correlation coefficient r=0.852.Conclusions64-slice spiral CT perfusion imaging can quantita-tively evaluate the haemodynamic condition and functional lesion of the kidney, classify the impaired kidney function. The perfusion parameters of the renal cortex and medulla had positive linear correlation with GFR.

Objective Minimally invasive treatment of orthopedic diseases is the general direction of future development of medicine.This study was designed to observe the effect of manual reduction combined with percutaneous kyphoplasty (MR+PKP) in the treatment of fresh osteoporotic vertebral compression fractures ( OVCF) in elderly patients. Methods Sixty OVCF patients aged 60-86 ( mean 72.3) years were randomly assigned to 2 groups of e-qual number to be treated by MR+PKP and PKP alone, respectively. Comparisons were made between the two groups of patients in the op-eration time, volumeand permeability of the bone cement injected,changes of the Cobb angle,restoration of the anterior height of the compressed vertebral bodies,pre-and post-operative Visual Analogue Scale ( VAS) pain scores, OswestryDisability Indexes ( ODIs) , and other differences observed before and aftersurgery. Results Op-erations were performed successfully in all the 60 cases.In the MR+PKP group, the mean operation time was 61 min, the mean volume of bone cement injected was 5.1mL with qualified distribution, and bone cement leakage occurred in 1 case without adverse reaction. Statistically significant differences were found in the pre-and post-operativeanterior height of the compressed vertebral bodies, Cobb an-gle, VAS scores, and ODIs (P<0.05).Compared with the PKP control, MR+PKP achieved a significant increase at 3 days and 3 months after surgery in the anterior height of the compressed vertebral bodies ([22.4±1.4] vs [26.8±8.1] mm and [21.4±4.2] vs [26.5±7.2]mm, P<0.05), and a decrease in the Cobb angle ([8.6±2.7] vs [8.1±2.1]°and [9.0±2.3] vs [8.3±1.8]°, P<0.05) as well as remarkably reduced VAS scores (4.1±2.2vs 3.1±2.0, P<0.05)and ODIs (23.0±3.1vs25.6±3.3, P<0.05) at 3 d postopera-tively. Conclusion MR+PKP, with its advantages of effective pain-relief, improvement of the height of compressed vertebral bodies, and reduction of bone cement leakage,is better than PKP alone for the treatment of OVCF in elderly patients.
