Objective To detect Nogo-A proteolytic fragment in CNS injury models and investigate its proteolytic mechanism as well as potential functions. Methods Western blot was performed to detect Nogo-A proteolytic fragment after spinal cord transection,brain ischemia and KA-induced cerebral cortex injury in rats. Results We detected Nogo-A proteolytic fragment in spinal cord transection and brain ischemia models,whereas no Nogo-A proteolytic fragment was found in KA-induced cerebral cortex injury model.Conclusion\ CNS mechanical and ischemic injury may induce the degradation of Nogo-A by certain mechanisms.

The 50% inhibition doses ( ID50 ) of tetrandrine and demethyl tetrandrine on DNA synthesis in L7712 and Sl80 cells are 2.6, 3 .5mg/ L and 27.5, 24.5mg/L respectively. The DNA synthesis inhibition is likely due to DNA template damage caused by both natural products. The inhibition of DNA, RNA and protein syntheses by tetrandrine or demethyl tetrandrine increased with incubating time. The inhibiting activities of two natural products on DNA and RNA synthesis are s-tronger than on protein. There are no differences either in inhibiting activity or in inhibiting mechanism between two natural products.

Objective To study the relationship between activity and virulence of secretory acid proteinase and extracellular phosphlipase of different Candida albicans isolated from various specimens.Methods 190 strains of Candida albicans were isolated from various specimens(sputum,blood,thrush,wound,secretion of vaginitis) of patients with Candida albicans infection in hospital.Milk-plate medium and egg-yolk medium were used respectively to test the activities of secretory acid proteinase and extracellular phosphlipase of Candida albicans.The suspension of two forms of Candida albicans(5?106CFU?mL-1) were injected to vein of tail in mice respectively in virulence test.The mortality and mean survival time of mice were observed in 1 month.The virulence was appreciated with the mean survival time of mice.Results All of 190 strains,the positive detectable rates of secretory acid proteinase and extracellular phosphlipase were 83.68% and 85.26%,respectively.Animal experimental results showed the activities of secretory acid proteinase and extracellular phospolipase in hyphal forms were significantly higher than that in spore form(P

Objective To describe epidemiological characteristics of scalp psoriasis in China,and to determine its influencing factors through a hospital-based,multicenter and large-scale survey.Methods An epidemiological survey was conducted on patients with scalp psoriasis in 42 hospitals in 11 provinces and 4 municipalities.A questionnaire was designed to collect general and clinical information of patients,including clinical type,lesion distribution,psoriasis scalp severity index (PSSI),aggravating factors,influence on quality of life,treatment course,degree of satisfaction with treatment,etc.Participants were asked to fill out the questionnaire with the help of well-trained dermatologists.Data were processed with the EpiData software.The WPS system and Epi Info 5.0 statistics software were used for descriptive analysis of the data.Results Totally,3 901 patients participated this study,and 3 586 valid questionaires were obtained.The mean age at onset of scalp lesions was (27.40 ± 13.34) years,and the male to female ratio was 1.6∶1 with a mean PSSI score of 13.61 ± 12.31.The hairline of the forehead was the most frequently affected area with the constituent ratio of forehead psoriasis being 74.3％ (2 663/3 586).The duration of scalp psoriasis reached 3 to 6 months every year in 1 136 (31.7％) patients,and the area affected by scalp psoriasis was less than 25％ of the total surface area of the scalp in 1 649 (46％) patients.The most frequent clinical presentation was scaling (92.1％),followed by erythema (80.6％),itching(76.7％),bunchy hairs (39.9％) and hair loss(18.0％).Disease aggravation was most frequently associated with seasons (76.7％),emotions (47.4％),stress (47.1％) and fatigue (46.6％).The quality of life (especially social,outdoor and entertainment activities) was reported to be negatively influenced by this entity to different degrees in 2 529 (70.5％) patients.Of these patients,583 (17.8％) received combination therapy (topical and systemic),with glucocorticoid ointment (27.5％),calcipotriol scalp solution (22.7％) and glucocorticoid-containing solution (11.9％) being the most commonly used topical drugs; only 38.6％ complied with medication requirements and doctors' advice for 3 to 5 weeks,and 35.2％ believed that the primary reason for poor compliance was unsatisfactory response to drugs.It was considered that an ideal drug for the treatment of scalp psoriasis should be highly effective (50.3％),safe (17.8％) and easy to apply (11％) with a rapid onset of action(11.9％).Conclusions Scalp psoriasis has a predilection for the hairline of the forehead with scaling as the main clinical presentation.Winter and spring seasons appear to be the most common aggravating factor of scalp psoriasis.The quality of life is negatively influenced to different degrees in many patients with scalp psoriasis.Topical corticosteroids plus non-hormonal drugs should be the first choice for the treatment of scalp psoriasis.Patients consider that the ideal drugs for the treatment of scalp psoriasis should be effective,safe,and easy to apply.

Objective To reassess the value of CT and clinical criteria as prognostic and severity indicators in acute pancreatitis and to investigate the correlation between them.Methods Of 65 cases of acute pancreatitis,the hospitalization days,fevering days and entire complications (including local and systemic complications)were regarded as clinical endpoints.CT criteria included Balthazar's plain CT scan score,necrosis score,CT severity index(CTSI) and London's PSI score.Clinical criteria included Ranson and APACHE Ⅱscore.Using analysis of variance,t-test and multiple linear regression analysis,the correlation between each criteria and the three clinical endpoints was examined as well as the relation between CT and clinical criteria.The power of each criteria and combination of CT and clinical criteria in predicting entire complications of AP was assessed and compared by using ROC analysis.Results The mean scores of PSI,Ranson and APACHE Ⅱamong three groups classified according to entire complications were significantly different.Except Balthazar's plain CT scan criteria,each criteria's mean scores in group with local complications was signifiantly higher than that in group without and entire complications was significantly more in sever group than that in mild group.Mean hospitalization days and fevering days were significantly longer in sever group than that in mild group with Ranson Score.PSI and Ranson score had linear correlation with fevering days,and Ranson score had linear correlation with hospitalization days.In CT criteria,a linear correlation was only found between PSI and Ranson score.ROC analysis showed the Az of Ranson score was the largest,and there was no increase in the Az when CT criteria were added to clinical criteria.Conclusion The predictive value of Ranson score and PSI are superior to that of others.Clinical criteria is superior in predicting systemic complications,whereas CT is superior in predicting local complications.There is no improvement in predicting entire complications of AP when CT criteria are added to clinical criteria.The findings of plain CT scan is found to be some laggard compared with that of clinic.CT scan and short follow-up are important in the evaluation of AP.

Platelet activating factor (PAF) is a biologically active membrane phospholipid mediator. In this study we investigated the effects of PAF on the lymphocyte proliferation, production of IL-2, natural killer cytotoxic factor (NKCF) and colony stimulating factor (CSF) by BALB/c mice splenocytes in vitro. The results showed that PAF inhibited lymphocyte proliferation at concentrations of 10-10~ 10-7 mol/L. CTLL-2, YAC-1 and munne bone marrow cells were used for the assays of IL-2, NKCF and CSF, respectively. Production of IL-2, NKCF and CSF from ConA stimulated murine splenocytes was significantly inhibited by PAF at 10-7 mol/L. Inhibition of spleen cells proliferation and secretion may play an important role in the pathological effects of PAF.

Objective To investigate the expression pattern and possible function of Nogo-A during neuronal growth. Methods E18 rat hippocampal neurons were primarily cultured both in high-density and low-density conditions. Immunohistochemistry and Western blot were performed to detect Nogo-A expression and distributional changes. Results Nogo-A was found in hippocampal neurons, mainly located in the cytoplasm, plasma membrane and neurites. It was detected at the proximal part of all neurites before axon formation. In axons, Nogo-A was enriched in the distal segment and axonal growth cone. In mature neurons, the fiber net work displayed a large number of Nogo-A immunoreactive varicosities. Conclusion The present results indicate that the neuronal Nogo-A may be involved in the process of neurite outgrowth and axonal projection.

Objective To study the relationship of sunlight exposure and photoprotection with clinical activity in systemic lupus erythematosus. Methods A structured questionaire was administered to 107 SLE patients, to assess their attitudes and behavior regarding sunlight exposure and photoprotection. The clinical manifestations, laboratory findings and treatment were evaluated. Results All patients were classified into two groups based on the duration of exposure to sunlight per day. Fourty-eight (44.86%) patients were exposed to direct sunlight for an average of less than one hour per day in one group and 59 (55.14%) for one hour or more in the other group. Twenty-four (22.43%) patients reported use of photoprotective measures in spring and summer. The patients in the former group had significantly lower incidences of photosensitivity, arthritis, alopecia, exacerbations, presence of anti-dsDNA antibody, decrease of complement C3, C4 and CH50 than those in the latter group(P
