    Four species of Ardisia (Myrsinaceae, Magnoliopsida) with rosette or low-lying leaves in China (including Hong Kong) have been found to be the hosts for 12 species of epiphyllous liverworts which belong to 4 families and 9 genera. However, no obvious species-specific hostepiphyte relationship could be recognized

    AIM: To evaluate the clinical efficacy of pattern scan laser photocoagulation(Pascal)on proliferative diabetic retinopathy(PDR).<p>METHODS: A total of 93 patients with retinopathy(186 eyes)were randomly divided into treatment group(96 eyes of 48 patients)who treated with panretinal photocoagulation(PRP)using Pascal at one time and control group(90 eyes of 45 patients)who treated with PRP using multi-wavelength krypton laser in 4-5 times. The visual acuity, FFA, OCT, visual field will be evaluated of each patient before and after the treatment.<p>RESULTS: The visual acuity findings were stated as below: the overall effective rate of visual acuity in treatment group is 85.4% while it is 82.2% in control group. The overall effective rate in two groups has no significant difference. The retinal sensitivity has no significant decrease in the treatment group while which decreased significantly in the control group.<p>CONCLUSION: The clinical efficacy of Pascal on treating the PDR is better than which of the regular argon laser. The field of vision has no significant narrowed after the Pascal treatment which can efficiently shorten the length of treatment and reduce the pain sensation
