Objective To study the molecular recognition of porphyrin compounds with carbohydrate molecular. Methods Fluorescent titration method was developed to explore the porphyrin and its metal porphyrin compounds interaction with carbohydrate compounds. Results The binding constants indicated that porphyrin and its metal compounds involved in this experiment could recognize carbohydrate compounds respectively, and interaction with lactose is stronger than glucose; Comparison with free porphyrin, metal ion Zn~(2+) and Fe~(3+) in the core of porphyrin compounds could enhance the binding capability with carbohydrate. Conclusion Porphyrin compounds has selective molecular recognition abilityto sugar molecular.

Ranibizumab is a recombinant rat monoclonal antibody fragment of the second generation humanized VEGF. Ranibi-zumab can bind all of active VEGF-A to inhibit the bond between VEGF-A and VEGFR1 or VEGFR2. As the results, the vascular en-dothelial proliferation and vascular permeability can be reduced, and the new vessels angiogenesis can be prevented. The article sys-tematically searched and summarized the relative literatures to offer high-quality evidences for the recent clinical application of ranibi-zumab in ophthalmology.

OBJECTIVE:To improve the formulation of Kangfu cream,in order to increase the stability of it. METHODS:Ac-cording to the problem that demulsion of zinc oxide and poor stability of Kangfu cream,orthogonal test was used to optimize the formulation of cream matrix with oil phase ratio (stearic acid-white vaseline-glycerol monostearate),with the amount of polysor-bate 80,triethanolamine and SG-10 as factors,using comprehensive score of glossiness,delicacy,consistence,coating and stratifi-cation(10 points as full mark)as index. The stability of the cream was validated and investigated,such as compatibility,heat-re-sisting,cold-resistant,lighting. RESULTS:The formulation were as follows as 100 g cream containing stearic acid 8 g,white vase-line 8 g,glycerol monostearate 6 g,polysorbate 80 4 g,triethanolamine 3 g,SG-10 2 g and appropriate amount of water. The comprehensive scores of the cream were >9.5 points (n=3). Compared with the cream prepared by previous formulation,the cream prepared by modified formulation had no significant change in appearance and color,and demulsion and layering hadn’t been found. CONCLUSIONS:Kangfu cream with better stability than original formulation is successfully prepared.

Objective To evaluate of the clinical efficacy and side-effect of 595nm tunable pulsed dye laser in treatment of children heamangioma of skin. Methods A retrospective study was conducted according to 76 children patients with heamangioma of skin (including 53 cases of nevus flammenus, 20 strawberry hemangioma and 3 cavernous hemangioma) treated with 595nm tunable pulsed dye laser. We evaluated the efficacy and side-effect of the treatment. Results The effectiveness rates were 83.2% and 86.63%, respectively, in nevus flammenus and strawberry hemangioma, but there were disappointed efficacy obtained in patients with cavernous hemangioma treated with 595nm tunable pulsed dye laser. There was 7.9% of the side-effect rate in the children with heamangioma of skin treated by 595 nm tunable pulsed dye laser. Conclusion There is satisfactory clinical efficacy and lower side-effect for children hemangioma treated by 595nm tunable pulsed dye laser.
