Objective To seek the evidence-based medicine (EBM) evidences of curative effects of intravitreous injection with triamcinolone acetonide (TA) for macular edema. Methods All articles of intravitreous injection TA for macular edema published in English or Chinese were picked up from databases of MEDLINE and CNKI and then evaluated according to EBM standard. The data in accord with research standard were selected by using excluding and including criteria, and classified according to the appraisal standard of clinical therapeutic documents. Results In the selected papers, none in gradeⅠevidence; 1 in gradeⅡevidence; 7 in grade Ⅲ evidence; 24 in grade Ⅳ evidence; and 19 in gradeⅤevidence. Forty-two papers reported that intravitreous injection with TA had significant effect for macular edema within 3 months, and the improvement of visual acuity was recorded in these papers. Regression of macular edema was recorded in 23 papers. Among 20 papers, side-effect was found in 93 eyes (31.41%) and the serious side-effect in 4 eyes (1.35%). Conclusions Intravitreous injection with TA has some curative effects for macular edema in short term, but the quality of current study has not been encouraging. There are no grade I document and lack of the study of validity in long term and essentiality and validity of retreatment. The special attention should be payed on the increasing persistency of efficacy and preventing the serious side-effects in the future investigation.

Objective To explore histopathological features in the nigrostriatal tissues of Parkinson’s disease (PD)and Parkisonism plus syndrome. Methods The substantia nigra and the striatum of 5 PD cases, 3 progressive supralnuclear palsy (PSP) cases and 3 multiple system atrophy (MSA) cases, and 5 normal aging control cases were examined by routine neuropathological methods and Gallyas-Braak staining and tau, ubiquitin and ?-synuclein immunohistochemistry. Pigmented neurons in the substantia nigra of PD, PSP, MSA cases and normal aging control cases were counted. The neuronal and glial cytoplasmic inclusions in the nigrostriatal tissues were observed. Components of the abnormal proteins were identified. Results Nerve cells in the substantia nigra of PD,PSP and MSA groups showed severe loss in number,especially the ventrolateral zone and the ventromedial zone. Compared with those in the normal aging control group,numbers of nerve cells in the ventrolateral zone of PD, PSP and MSA groups decreased to 37.5%, 24.2%, 33.8% in the right side, and 48.0%, 25.8%, 33.9% in the left side respectively. There were ?-synuclein and ubiquitin-positive Lewy bodies in the substantia nigra of PD. A lot of tau-positive, argyrophilic globous neurofibrinary tangles, tuft-shaped astrocytes and coiled bodies in the substantia nigra and the striatum of PSP were observed.Severe loss of neurons and gliosis in the caudate nucleus and putamen of MSA were found. In addition, ?-synuclein and ubiquitin-positive glial cytoplasmic inclusions were found in the substantia nigra and striatal region of MSA. Conclusions Lewy bodies in PD and glial cytoplasmic inclusions in MSA are related to abnormal depositions of ?-synuclein and ubiquitin.Neuronal and glial cytoplasmic inclusions in PSP are related to abnormal aggregation of tau.

BACKGROUND: Synaptic density, a key index of structure and function of brain tissues, is related to cognitive function. Synaptic loss occurs during human brain aging and in Alzheimer disease (AD), inducing the changes of synaptic density.OBJECTIVE: To observe quantitative synaptic alterations in human brain and changes of synaptic density in different parts during normal aging so as to compare them with those of AD patients.DESIGN: Sampling survey.SETTING: Senile Neurological Department of General Hospital of Chinese PLA.PARTICIPANTS: Pathological data were selected from General Hospital of Chinese PLA from June 1996 to December 2002. Inclusion criteria: had no major nervous system diseases and neuropathological changes. Brain tissues of 28 corpses in normal aging group, 23 males and 5 females aged 23-100 years with an average of (65±22.8) years, were obtained at autopsy.All corpses were divided into three groups according to their age, namely,adult group (23-55 years old, n=9), senile group (64-72 years old, n=7),and >75 group (76-100 years old, n=12). Cerebral hippocampal samples of other six corpses diagnosed with AD were selected from clinic. The corpses included 5 men and 1 woman aged 76-94 years with an average of (83±7.7) years.METHODS: Response intensity of synaptophysin immunochemistry remained stable after 4-8 hours of death, so brains were obtained at autopsy after 8-72 hours of death and fixed with 4% formalin for at least 6 weeks.In normal aging group, tissues were taken from left superior frontal gyrus,striatal area of left occipital lobe, left putamen (striatum section, including head of caudate nucleus), and left hippocampus (from lateral geniculate body section to medial occipitotemporal gyrus). In AD cases, tissues were taken from left hippocampus of 4 corpses and right hippocampus of other 2. All sections were stained with hematoxylin eosin (HE), toluidine blue and synaptophysin immunostaining (rabbit anti-human synaptophysin polyclonal antibody from Beijing Zhongshan Biotechnology Co., Ltd.). Morphology and distribution of positive objects in synapse immunologic reaction were observed under the light microscope. Relation between absorbance in each region and age was determined with Pearson's coefficient. Differences among groups were analyzed with nonparametric test, and the differences in hippocampal CA3 area between > 75 group and AD group were analyzed with the same test.MAIN OUTCOME MEASURES:① Absorbency of synaptophysin at various sites of normal aging group and correlation with age; ② absorbance value in CA3 area between AD patients and advanced aged normal subjects (>75 years) was compared.RESULTS:All the 34 cerebral samples entered the final analysis.①Synaptophysin-positive granules of various size were scattered through neocortex, putamen and hippocampus, neuronal somata, neuroglia, vessels and white matter. Density was particularly strong over layers Ⅱ and Ⅲ in frontal lobe, and layer ⅣV in occipital lobe. ② Synaptophysin density was negatively correlated with age, which was -0.688 in frontal lobe, -0.592 in occipital lobe, -0.458 in putamen and -0.619 in hippocampal CA2 area,respectively (P = 0.000, 0.001, 0.014, and 0.000). ③ Significant difference in synaptic density in CA3 area was found between AD patients (0.031 3±0.003 0)and normal subjects over the age of 75 (0.040 7±0.005 3) (Z=-2.997, P=0.001)in nonparametric test.CONCLUSION:① Synaptic density was found to decrease in frontal lobe, occipital lobe, CA3 area of hippocampus and putamen with age; the changes had significant correlation with age.② Synaptic density of AD patients was lower than that of normal subjects, and their cognitive hypofunction was related to synaptic loss. ③ All tissues were obtained after 8-72 hours of death and fixed over 6 weeks, which to the greatest extent reduced the effects of tissue autolysis and formalin fixation on the results.

Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.
