The effect of lid hygiene on the tear film and ocular surface,and the prevalence of Demodex blepharitis in university students

AimTo evaluate the effect blepharitis lid cleansers have on the tear film and ocular surface, and to examine the prevalence of Demodex folliculorum in a young population.MethodsForty-eight university students completed a randomised, controlled, investigator-masked, eight-week clinical trial. Three eyelid hygiene products were investigated: blepharitis eyelid cleanser (OCuSOFT® Lid Scrub® PLUS foam), diluted baby shampoo (10% Johnson’s® No More Tears ®) and a tea-tree based face wash (dr.organic®). Cooled boiled water was used as a control. Subjects attended for four visits: baseline, two weeks, four weeks and eight weeks. At each visit, subjective symptoms, non-invasive tear break up time, ocular surface staining and Demodex folliculorum investigation were assessed to evaluate any positive or negative effect on the tear film and ocular surface. Osmolarity was also measured at baseline and week eight only.ResultsThe overall prevalence of Demodex folliculorum found at baseline was 15%. Subjective symptoms improved in all groups, including control. There was no significant difference in mean osmolarity between the groups or within each group after eight weeks. There was a significant increase in osmolarity inter-eye variability in the baby shampoo group (5.5 ± 5.4 vs 15.2 ± 9.5; p = 0.03). There was no significant change in non-invasive tear break up time or ocular surface staining demonstrated after eight weeks of eyelid hygiene.ConclusionA low prevalence of Demodex folliculorum can be found in a young population. All blepharitis lid cleansers used demonstrated subjective improvement in symptoms, with no negative effects on tear break-up time or ocular surface staining. The blepharitis eyelid cleanser and tea-tree based face wash revealed no adverse effect on mean osmolarity or inter-eye variability. Similarly, baby shampoo did not cause a significant increase in mean osmolarity, however, a significant increase in inter-eye variability was found; suggesting a possible increase in ocular surface inflammation.

纳米HAP唾液蛋白与葡聚糖吸附性能研究

分别采用考马斯亮蓝蛋白测定法和酚．硫酸葡聚糖测定法，比较了不同性状羟基磷灰石粉体（HAP）对唾液蛋白和葡聚糖的吸附能力，研究了纳米HAP吸附唾液蛋白和葡聚糖的动力学和热力学特点。结果表明，对唾液蛋白和葡聚糖的吸附能力纳米HAP明显强于普通HAP，煅烧纳米HAP（nHAPc）又优于未经煅烧的HAP（nHAP）；nHAPc对唾液蛋白的吸附属于受颗粒表面ζ电位控制的电性吸附，而nHAPc对葡聚糖的吸附则很可能属于单层特异性吸附。
