ABSTRACT
Objective:To predict the target of active components of Drynariae Rhizoma by the network pharmacology, map related targets of osteoporosis (OP), and analyze key nodes of interaction topologically, so as to comprehensively explore the pharmacological mechanism of anti-op of osteoclasts. Method:Firstly, the main active components of Drynariae Rhizoma were screened out from TCMSP based on the pharmacokinetic characteristics, and the related targets were predicted by Pubchem and Swiss Target Prediction database according to the Two-dimensional/Three-dimensional(2D/3D)structural similarity. Then, through Online Mendelian Inheritance in Man (OMIM) and Pubmed text, known OP therapeutic targets were mined, based on putative targets, String database was imported to build Drynariae Rhizoma treatment target OP interaction network diagram. With the help of CytoNCA software, the interaction key nodes were topologically identified according to relevant node parameters, and then imported into String database to build the protein interaction network graph. Finally, biological functions and metabolic pathways of key nodes were analyzed through DAVID database. Result:Sixteen active components of Drynariae Rhizoma were screened out, and 118 related targets were predicted according to the target prediction technique. Totally 316 known therapeutic targets for OP were retrieved. The protein interaction network was constructed according to the String network database. A total of 97 key nodes were screened via CytoNCA topology. The enrichment analysis showed that Drynariae Rhizoma may play an anti-osteoporosis role by regulating stem cells, osteoblasts, osteoclasts and immune cells through multiple signaling pathways in aspects of proliferation, differentiation, immunity and oxidative stress. Conclusion:Studies based on network pharmacology have shown that Drynariae Rhizoma may play an anti-op role through direct or indirect targets and multiple major signaling pathways and affect the proliferation and differentiation of multiple types of cells, in order to provid a scientific basis for explaining the material basis and mechanism of Drynariae Rhizoma's anti-osteoporosis effect.
ABSTRACT
AIM:To explore efficacy of the different kinds of artificial tears treatment in patients with xerophthalmia after phacoemulsification combined with intraocular lens implantation.METHODS:Totally 280 patients (280 eyes) with xerophthalmia after operation in our hospital from January 2015 to June 2016 were selected.According to the different treatment methods, they were divided into control group (n=70;treated with tobramycin and dexamethasone eye ointment 3 times per day for 1wk, levofloxacin eye drops 3 times per day for 1wk, pranoprofen eye drops 4 times per day for 1mo), polyacrylic acid group (n=70;besides the treatment of control group, polyacrylic acid was used 4 times per for 1mo), polyethylene glycol group(n=70;besides the treatment of control group, polyethylene glycol was used 4 times per for 1mo) and sodium hyaluronate group (n=70;besides the treatment of control group, sodium hyaluronate was used 4 times per for 1mo).The tear film break up time (BUT), Schirmer Ⅰ test (SⅠt), symptoms of dry eye and corneal staining in four groups were observed.RESULTS:(1) BUT:The BUT of the four groups significantly increased after treatment(P0.05);sodium hyaluronate group was significant lower than other groups in corneal staining score at 3wk and 1mo after treatment(P<0.05).CONCLUSION:Artificial tears in the treatment of xerophthalmia after cataract phacoemulsification combined with intraocular lens implantation has better clinical efficacy, which contains sodium hyaluronate may be the better than others.
