An HPLC method was established to simultaneously determine the five sesquiterpene lactones, carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekinand 11(13)-dehydroivaxillin in Carpesium abrotanoides. Samples were analyzed on a kromasil C18 column (4.6 mm x 250 mm, 5 µm); mobile phase: A was acetonitrile, B was water, with gradient elution; flow speed: 1.0 mL · min(-1); detection was carried out using a photodiode array detector at 211 nm; temperatureof column: 30 °C. The five sesquiterpene lactones were well separated with good linear correlations in the range of 0.270-2.700 (r = 0.999 7 ), 1.336-13.360 (r = 0.999 6), 0.258-2.580 (r = 0.999 7), 0.238-2.380 (r = 0.999 9), 0.490-4.900 µg (r = 0.999 9) for carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekin and 11 (13) -dehydroivaxillin. The average recoveries of these five sesquiterpene lactoneswere 96.78%-98.41% (RSD 1.3%-2.9%). The method was simple, repeatable and stable, which could be used for quality control of C. abrotanoide.

Objective　To detect the features of MRI of children leukodystriphies and to provide a heplful method for clinical diagnosis.Methods　The MRI examination was performed in 50 children with leukodystrophies and the cerebral lobes and cerebral special structures involved by lesions were analyzed.Results　1.There were dominant signs of involving parietal and occipital lobes in ALD,besides the two lobes,the frontal lobe was also involved easily in MLD.All lobes were involved in CD and PMD,and frontal lobe was involved in AD early.The central white matter was involved mainly in ALD,but the central white matter was involed only in MLD and the periphery white matter was spared.The central and periphery white matter were all involved in CD,PMD and AD.Furthermore,the cerebellar white matter is also easily involved in ALD and CD.2.The splenium of corpus callosum was mainly involved in ALD,and the splenium,body and knee of corpus callosum were all involved in MLD.But in CD,PMD and AD,the corpus callosum was spared.The back of the posterior limb of internal capsule was involved in ALD,but the all posterior limb of internal capsule was involved in MLD,and the all internal capsule was involved in CD and PMD.On external capsule,ALD involves its posterior part,but CD and PMD involve its all section.A prominet feature of ALD was involving the corticospinal tract of stem and other leukodystrophies don′t involve the corticospinal tract of stem beside one case later-onset GLD.In addition,the lateral lemmiscus was involved easily in ALD,and thalamus was also involved in ALD,MLD and PMD.Conclusion　As a noninvasive,safe and sensitive method,MRI can be used to find the leukodystrophies early.There are relatively characteristic features in different leokodystrophies,which is useful to clinical diagnosis.

Objective To investigate the MRS characteristic of low T_2 signal in peripheral zone of prostatitis and prostatic carcinoma(Pca) and to evaluate the role of MRS in the discrimination of prostatitis and Pca.Methods After biopsy,24 patients with Hypointense T_2 signal in prostatic peripheral zone were divided into two groups:prostatitis and Pca.3D MRS was performed on the low T_2 area of peripheral zone to measure the ratio of(Cho+Cre)/Cit.Results The mean ratio of(Cho+Cre)/Cit in low T_2 area of prostatitis was 0.98?0.17,whereas that of Pca was 1.41?0.31,statistically significant difference was detected(t=8.89,?

Objective To study MR findings in 20 children aged from 10 months to 14 years with mitochondrial encephalomyopathy.Methods MRI evaluations were done in 20 children with mitochondrial encephalomyopathy proved by muscle biopsy and biochemical laboratory examinations.Results Brain parenchymal lesions in all cases were low signal intensity on T 1-weighted and high signal intensity on T 2-weighted images.Brain atrophy was showed in different degrees in 8 children.18 patients had involvement of gray matter,10 had only the deep gray matter involved and 4 cases had both the deep gray matter and the cerebral cortex involved simultaneously.4 patients showed deep gray matter abnormalities and cerebral infarction with involvement of cortex and subcortical white matter.2 patients had exclusively involvement of white matter,which were nonspecific white matter changes of the trigonal area.Conclusion MRI findings in mitochondrial encephalomyopathy are varied when gray matter especially deep gray matter involved,brain atrophy,untypical infarction and involvement of peripheral white matter are showed on MR,and associated with a variety of neuromuscular symptoms in children mitochondrial encephalomyopathy should be consider.

Objective We retrospectively studied the MRI and MRA appearances of 10 patients,(6 children,4 adults) with Moyamoya disease.Methods MRI and MRA images were analyzed.For the MRA images,it was concerned that whether there were occlusive changes of the internal carotid artery and middle cerebral artery and whether there were collateral vessels.For the MRI images,the locations of the infarct lesions were studied.Results For the MRA images,the internal carotid arteries and the middle cerebral arteries were observed stenosis,and collateral vessels were formed in cerebral hemispheres.There were no remarkable differences between the children and adult groups with regard to the occlusive changes or to the flow void sign on MRA.However,Moyamoya disease in children exhibited a significant increase in the cortical and subcortical infarction(75%,9/12).In contrast,there were much more deep white matter infarctions in the centrum semiovale and basal ganglia in the adult group(87.5%,7/8)than in the children group(33.3%,4/12).Conclusion MRI and MRA are the method of choice in diagnosis of Moyamoya disease.The differences in the site of infarctions between the childhood and the adult Moyamoya disease observed on MRI may explain the differences in the clinical presentation.

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

Objective To characterize the MR imaging findings in different types of neuronal ceroid lipofuscinosis (NCL) in childhood. Methods Six children with NCL and 6 age-matched control subjects were examined by using MRI. There was 2 patients with infantile NCL, 2 with late-infantile NCL, and 2 with juvenile NCL. Results The cerebral atrophy was found in patients with infantile NCL, but the cerebellar atrophy was found in patients with late-infantile NCL and juvenile NCL; Hyperintensity in the centrum semiovale or periventricular white matter on T 2WI was revealed in all cases; Decreased T 2 signal was seen in the thalami in five patients, except for 1 juvenile NCL; Decreased T 2 signal in the basal ganglia was seen in the 2 case with late-infantile NCL. No abnormal change was found in the control subjects. Conclusion MRI is of great value in demonstrating the early changes of NCL. MRI especially facilitates the classification and early diagnosis of NCL.
