Objective To explore the characters of cognitive dysfunction for first-ever lacunar infarction (LI). Methods 136 first-ever diagnosed LI patients were evaluated with Alzheimer's disease assessment scale (ADAS) 72 h, 2 weeks, 1 month, 3 months and 6 months after attack. The scores were compared with the baseline and those of 76 normal control. Results Memory: during the first 72 h, significant difference was shown between the every location of LI (including the basal ganglia, corona radiate,frontal lobe, temporal lobe,parietal lobe, periventricular location, centrum semiovale, thalamus) and normal control (P<0.05); but between the certain location of LI and that of normal control 2 weeks, 1, 3 and 6 months after attack (P<0.05). Language: there was significant difference between every location of LI and normal control 72 h, 2 weeks and 1 month after attack (P<0.05), but between the certain location of LI and that of normal control 3 and 6 months after attack (P<0.05). Practice: there was significant difference through every visit time point of all the LI patients compared with normal control (P<0.05). Attention: Significant difference (P<0.05) was found between every location LI patients and normal control 72 h after attack, but between certain location LI patients and normal control 2 weeks, 1, 3 and 6 months after attack (P<0.05). Orientation:LI was insufficient to cause to decline in orientation. Conclusion There are mild to severe cognitive dysfunctions in the first-ever diagnosed LI patients, which need pay attention to and intervene in time.

The pulse wave velocity(PWV)known as one of important monitoring methods in crowd more can precisely reveal the occurrence of cardiovascular events.The brachia-ankle PWV(baPWV)is referred to cosmically epidemiological study in crowd.PWV is known as a vicarious mark of arteriosclerotic burden and an independent risk factor.Moreover,used for decision the therapeutic effect.Our study initially showed that PWV was only a mark of cardiovascular events and was not a predict end point.

OBJECTIVE To investigate the diagnostic value of 131I-SPECT/CT fusion images in detecting the metastases of differentiated thyroid carcinoma(DTC)in the regions of the head,neck and superior mediastinum.METHODS 131I-SPECT/CT fusion images was preformed for 30 patients with DTC,and the results of image were compared with the pathology after surgery.RESULTS There were 110 cases positive findings in 115 metastatic lesions with 131I-SPECT/CT fusion images examination(95.65%).5 cases of the metastatic lesions showed negative in 131I-SPECT/CT(4.35%).There was no false positive case.CONCLUSION 131I-SPECT/CT fusion images can detect and locate the metastasis and exclude the false positive results accurately.It is a good method to detect the cervical and superior mediastinal metastatic lesion in differentiated thyroid carcinoma.

Objective To study the chemical constituents from the stem bark of Daphne giraldii. MethodsThe chemical constituents in the alcoholic extract from the stem bark of D. giraldii were isola-ted and purified using liquid/liquid extraction and silica gel column chromatography. The structures of the isolated compounds were determined on the basis of NMR, and mass spectra. ResultsSeven compounds were isolated from the alcohol extract. Their structures were identified as E-octadecyl caffeinate (Ⅰ), (+)-nortrachelogenin (Ⅱ), daphnoretin (Ⅲ), daphneticin (Ⅳ), 7, 8-dihydroxy coumarin (Ⅴ), 7-hydroxy coumarin (Ⅵ), and luteolin (Ⅶ) on the basis of 1H-NMR, 13C-NMR, and MS. ConclusionCompound Ⅰ is a new one. Compounds Ⅱ, Ⅳ, and Ⅶ are isolated from the title plant for the first time.

Objective To discuss the diagnosis and treatment of AVM bleeding without DSA in the basic hospital.Methods Clinical difference of intracerebral hemorrhage was revienly analyzed between arteriovenous malformation and hypertensive intracerebral hemorrhage.Results Boths were different at sick ages,position and shape of haematoma,change of blood pressure after bleeding,CT scan of preoperative and view in operative.Surgery was effective.Conclusion Initial diagnosised of AVM bleeding is affirmed,according to patient's age,using mannitol is effective to control blood pressure after bleeding and display of CT scans preoperative.Final diagnosis is confirmed in operation without DSA at basic hospital.Treatment of AVM bleeding with surgery is effective.

Objective To explore the correlation between imaging features and pathological findings of alveolar soft part sarcoma (ASPS).Methods The clinical data,radiographic images and pathological characteristics of seven patients with histopathologically proved ASPS from 2003 to 2009 were retrospectively reviewed.Digital radiography (DR),plain CT,pre and post-contrast MR and DSA were performed in all patients.HE staining and periodic acid-Schiff (PAS) staining were used in pathological examination and CD34 were marked in immunehistochemical study.Results All patients were females.Their age ranged from 16 to 37 years with median of 24 years.Two tumors were located in pelvics,three were located in thighs,and two were located in legs.DR and CT plain scan features of ASPS were non-specific.MR demonstrated the tumors with large diameter and well defined margin locating in the deep tissues.Tumors were hyperintense on T2-weighted and T1-weighted images with many flow void vessels and persistent remarkable enhancement.There were numerous vessels with arteriovenous fistula on DSA.Pathological examination revealed solid nests of several polygonal tumor cells arranged in an alveolar pattern and separated by thinwalled,sinusoidal vascular channels.Tumor cell were noted on periodic acid-Schiff (PAS) stains.And the endothelial cells of sinusoidal vascular channels were positive on CD34.Conclusions As a malignant tumor which predominantly developed in deep location of trunk or extremities in young females,numerous void signal and hyperintensity on T1-weighted were the features of ASPS on MR.Numerous vessels could also be confirmed on DSA.These image findings were correlated closely with the pathological manifestations.
