Objective To observe the changes of the outer ce ll wall in resting phase and during sw elling process of conidia of Aspergillus fumigatus,and the distribution of fibronectin receptors on conidia surface.Methods After being harvested with 3.5~4.0?m steel filters,the conidia were resuspended in RPMI 1640+10%FBS medium.The specimens were observed by the scanning electron microscopy after incubation for 0,2,4,6hours a t37℃respectively.The same amount of conidia was resuspendesd in PBS buffer,and put the suspension on 50?g /ml fibronectin coated microtitre plate,after incubation for 3hrs at 37℃,t he conidia were washed three times wi th PBS.Then rabbit antifibronectin antibody and fluorescein isothiocyanate(FITC)conjugated goat anti-rabbit immunoglob-ulin antibody were added,respectiv ely.After digesting with trypsin,t he conidia were washed again with PBS and examined by immuno-confocal microscopy.Results Acharacteristic echinulate pattern of protrusions was shown in the cell wall surface of resting coni dia.During swelling process,the ec hinulate layer of swollen conidia wa s gradually disintegrated,and almost complete ly shed 4hr later.Then,a smooth cell wall layer covered by some strands of fib-rillar material was shown.Binding o f fibronectin to the surface of conid ia was revealed by immuno-confocal m i-croscopy.FITC was homogeneously ad hered to the protrusions on the conid ial outer cell wall layer.Conclusion In resting phase the conidia of A.fumigatus express high levels of fibronectin r eceptors on their surface,they are h o-mogeneously distributed over the ex ternal echinulate layer of the conid ia,and shed gradually during the swe lling process.

Objective: To study the bioactivity of human cementum extract . Methods: Cementum was harvested from freshly extracted heatlhy teeth and cementum extract was prepared by guanidine. Human gingival fibroblast and MC3T3 E1 osteoblast were cultured. The cells were incubated in DMEM with cementum extract concentration 0, 2.5, 5, 10 or 20 ?g/ml for an hour respectively, the cell attachment rate was measured by cell counting. The attachment rate of the cells in different incubation time(30 min,60 min, 90 min, 120 min) in DMEM containing 10 ?g/ml cementum extract was also assayed.Results: The extract increased the cell attachment rate in a concentration and time dependent effect. The extract at the concentration of 10 ?g/ml and with exposuse time of 90 min gave the most effective increase of cell attachment. Conclusion: Human cementum extract prepared by guanidine contains some bioactive proteins that promote the attachment of gingival fibroblasts and osteoblasts.

The arsenic compounds including arsenic trioxide and arsenic sulfide have played a crucial role in the clinical treatment of hematologic malignancies and solid tumors. Arsenic agents can induce tumor cells differentiation, apoptosis and autophagy, eliminate leukemia-initiating cells, and directly bind to the target proteins. This paper reviews the mechanism progress of arsenic agents in various tumors to further understand the intricate anti-tumor mechanisms of arsenic agents and to expand its therapeutic spectrum.

The visual acuity testa were performed in 8219 children(16 438 eyes)under 5 years of age with sound and light toys,electric torch and a retinoscope.The general ocular examination and mydriatic optometry were also performed for the ametropia.In 8219 children 61 were found to have dominant strabismus,including 59 cases of concomitant strabismus and 2 paralytic strabismus.AbnormaJ refraction was detected in 404 children(739 eye)accounting for 4.92%,including 68 cases of anisometropia (0.83%).In 16 438 eyes 621(3.78%)were moderate or hyper-presbyopia;53(0.32%)were myopia;65 (0.40%)were mixed astigmatism.The vision acuity test described above is a simple and convenient method suitable for children under 5 who are not able to read the conventional test chart.

OBJECTIVE:To regulate the management of operation drug and promote medication security. METHODS:Based on the relevant principles in the standard of JCI,the practice about establishment of operation pharmacy in our hospital was intro-duced,and it were stated from two aspects which included working mode and effects. RESULTS:The working mode were format-ed by definiting the duties and working flow of pharmacist,anesthetist and liaison man. The establishment of operation pharmacy, which brought operation drugs into the unified management system of our hospital,saved manpower and improved work efficien-cy,refined the management of drugs in all aspects,improved the management of drug safety level,strengthened drug expiration date management,implemented the reporting of adverse drug reactions(event)and collecting of medication(potential)errors. The established mode conformed to the relative standard of JCI including preparation,grant,storage and collection of ADR of drug. CONCLUSIONS:The established drug management of operation pharmacy promotes standardized administration of surgery drug, which guarantees the drug use safety of patients.

Objective To explore the value of time-invariant CTA in assessing collateral circulation of patients with acute ischemic stroke and assisting clinicians in predicting clinical outcomes.Methods The score of collateral circulation was compared between single-phase and time-invariant CTA.NIHSS score was calculated at admission and two weeks after admission.A 50% or greater decrease in NIHSS score over two weeks was considered as major neurologic improvement,which showed good clinical outcome;otherwise,it indicated bad outcome.The predictive ability of time-invariant CTA for clinical outcomes was assessed based on ROC curves.Results Compared with single-phase CTA,more collateral vessels could be viewed on time-invariant CTA.The average score of collateral circulation on time-invariant and single-phase CTA was 1.50±0.69 and 1.15±0.49 respectively (P=0.006<0.05 ).Time-invariant CTA had the moderate predictive ability for clinical outcomes in patients with acute ischemic stroke (AUC=0.810;P=0.032<0.05). Conclusion The time-invariant CTA showed potential value in assessing collateral circulation of patients with acute ischemic stroke and assisting clinicians in predicting clinical outcomes.
