Objective:To study the influence of morphine on the expression of nestin in the ependymal epithelia,central gray and hippocampal formations in mice.Methods:Twenty health mice were evenly randomized into control group and experiment group.Mice in the control group were injected with normal saline(0.1 ml daily)and those in the experimental group were injected with morphine (0.1 ml,1 mg daily).Thirty days later,the mice brain samples were harvested and made into paraffin sections.Immumohistochemical ABC technique was used to observe the expression of nestin under light microscope.The images were analyzed with the image analytical system.Results:In the control group,the ependymal epithelia,the central gray,the periventricular gray substances and the hippocampal formations had weak expression of the nestin,with a mean gray scale of 150.98?13.31;there were 5 kinds of nestin-positive cells:(1) the basal cells of ependymal epithelium,(2)cells distributed in the periventricular gray substance and the deep lamella of central gray, (3)cells distributed in the superficial lamella of central gray,the subiculum,the parahippocampal gyrus and the cortex inⅡ,Ⅲlayers of the entorhinal area,(4)cells frequently seen in the rectum of midbrain and the subiculum,and(5)cells distributed in the tectum of midhrain,the hippocampus,gyrus dentatus,parahippocampal gyrus and the cortex in V layer of the entorhinal area;the density of nestin in the subiculum and entorhinal area was(7.20?1.23)mm~2.In the experiment group,the ependymal epithelia,the central gray,the periventricular gray substances and the hippocampal formations had positive expression of the nestin,with the mean gray scale being 133.03?22.28;the density of the above-mentioned 5 kinds of cells increased;the density of nestin in the subiculum and entorhinal area was(10.50?1.43)mm~2.The mean value of gray scale and nestin-positive neurons were significantly different between the 2 groups (P

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

ObjectiveTo investigate the clinical features and risk factors of patient with Wegener's granulomatosis complicated with pulmonary infection.Methods Patients with Wegener's granulomatosis admitted to our hospital in the past 11 years were retrospectively analyzed.Comparisons between groups were performed by t tests or Fisher test.ResultsPulmonary infection occurred in 27 cases with an incidence rate of 29％.Twenty-six percent of pulmonary infections occurred at the initial diagnosis,and 44％ occurred within 6 months,while 30％ occurred later than 6 months.The clinical manifestations of pulmonary infection were productive cough (89％),hemoptysis (63％),fever and fatigue (56％),chest pain and pactoralgia (33％).The most common causative pathogen were bacteria(59％ ),fungi(37％ ),and tubercle bacillus(37％ ).Sinus infection(P=0.01),hypoproteinemia(P=0.03),hypoimmunoglobulinemia (P=0.007),and methylprednisolone pulse therapy(P=0.002) were the risk factors for pulmonary infection.ConclusionThe occurrence of Wegener's granulomatosis complicated with pulmonary infection is high within 6 months.The most common clinical manifestation is productive cough.The most common causative pathogens are bacteria,tubercle bacillus and fungi.Sinus infection,hypoproteinemia,hypoimmunoglobulinemia,and methylprednisolone pulse therapy are risk factors of pulmonary infection.

To evaluate the automated segmentation algorithm for detection of intra - retinal layers to process images obtained from ultra- high resolution optical coherence tomography ( OCT ) . Graph theory and the shortest path search based on dynamic programming were applied to automatically segment the 8 intra - retinal layers. We experimentally verified the accuracy and reliability of the algorithm. The results showed that the intra-retinal layer boundaries between automated and manual segmentations matched well. The algorithm successfully segmented the intra- retinal layers in glaucoma, high myopia, and retinitis pigmentosa patients. The proposed automatic segmentation for intra-retinal layers provides a promising tool for quantitative analysis in clinical diagnosis and treatment.

AlM: To investigate the clinical efficacy of treatment of dacryocystitis combined with canalicular obstruction by endonasal endoscopic dacryocystorhinostomy with canalicular intubation.
METHODS: A total of 27 cases of dacryocystitis combined with canalicular obstruction were treated by endonasal endoscopic dacryocystorhinostomy with canalicular intubation. Canalicular obstruction was treated by laser under dacryoendoscopy and antegrade intubation.
RESULTS: For 27 cases, operations were successful, with no complications. All patients were followed up for 6mo, 25 were cured, 2 were effective with no failed. The cure rate was 93%.
CONCLUSlON:Treatment of dacryocystitis combined with canalicular obstruction by endonasal endoscopic dacryocystorhinostomy with canalicular intubation has clear field, minimal invasion, quick recovery, exact effect and less recurrence, so it is worthy of promotion.
