METHODS: Total of 54 elder Qiang people with dry eyes (108 eyes) were examined by cluster sampling. In the similar habitation region of Han people, 80 (160 dry eyes) Han people were analyzed as the control group. The bacteria was separated from the inferior palpebral conjunctiva, then inoculated on blood plate for 48 hours and identified. RESULTS: Totally 24 strains of bacteria were cultured in either Qiang minority or Han c populations with 3 strains of them existed in both ethnic groups. The commonest bacteria in conjunctival sac in two ethnic groups were non-pathogenic bacterium. The composition of Corynebacterium in Han people (54.1%) was significantly higher than that in Qiang minority (27.4%) (chi(2)=11.6721, P=0.0006). The percentage of Sphingomonas Paucimobilis in Qiang people was higher than that in Han people (chi(2)=18.6442, P=0.0000). However, there was no significant difference between Qiang minority and Han people either in bacterial positive rate in conjunctival sac, or the composition of bacteria species and strains, or the composition of staphylococcus epidemids between two ethnic populations. CONCLUSION:There was no significant difference of bacterial positive rate in conjunctival sac from the elder of Qiang minority and Han people with dry eye, but the species of bacteria were different.展开更多
Purpose:The antiseptic effectiveness of 5% anerdian Ⅲ, 0.016% gentamicin,and 0.5% tobramycin solutions in pre-surgical irrigation of conjunctival sac were compared.

Methods:A total of 295 cataract patients (302 eyes) who had undergone phacoemulsification aspiration combined with intraocular lens insertion. (IOL).were recruited in this prospective study.Operative eyes were given 0.3% levofloxacin eye drops for 3 days and then were randomized into three treatment groups:anerdian. (A), gentamicin (B) and tobramycin (C).The patients received conjunctival sac irrigation using the respective solutions at 10 minutes preoperatively.Conjunctival sac sampling was performed before and after irrigation and the samples were used for subsequent bacterial culture and swab tests. The positive culture rate was used as the main outcome. Results:The positive rates of bacterial culture before conjunctival sac irrigationwere 17.31% (18 eyes) in group A, 13.86% (14 eyes) in group B and 17.3% (14 eyes) in group C.Post irrigation,the positive rates in the three groups decreased to 5.76% . (6 eyes),5.94% . (6 eyes) and 7.22% (7 eyes), respectively. The positive rates among the three groups did not differ significantly.However,the positive rate in group A only significantly differed before and after the irrigation (P<0.05). No toxic or allergic reactions were observed on the ocular surface of any patient after irrigation. Conclusion: The antiseptic effects of the three types of con junctival sac irrigations did not differ. (Eye Science 2013; 28: 20-23)展开更多
