Chinese medicinal formulae( CMF) were often used in the clinics of traditional Chinese medicine (TCM) which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. In current studies, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were often neglected. Thus, we put forward integrative pharmacology, which could integrate the correlation between CMF and biological organisms from multi-levels and multi-dimensional views. Integrative pharmacology would reveal the molecular mechanism of CMF for ailments treatment and screen out effective material systematically, which would be the new paradigm of TCM research.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.

Objective To determine the risk factors of light perception and no light perception appearenee after vitrectomy for pro-liferative diabetic retinopathy (PDR). Design Retrospective, noncomparative case series. Participants 242 patients (288 eyes) who un-derwent vitrectomy for PDR. Methods 288 eyes of participants from 2002 to 2006 at Beijing Tongren Eye Center were reviewed. Cases that had postoperative visual acuity of light perception (LP) and no light perception (NLP) were recorded and PDR stages, traction reti-nal detachment involving macula, postoperative retinal detachment, postoperative vitreous hemorrhage, postoperative neovascular glauco-ma and re-operations were analyzed. Main Outcome Measures Postoperative complications, PDR stage, macular disorder. Results Subjects were divided into two groups. LP/NLP group included eyes that had postoperative visual acuity of light perception and no light perception (totally 14 eyes in this group). Another group (control group) included eyes that had postoperative visual acuity of hand mo-tion or better (totally 274 eyes in this group). When compared with control group, the LP/NLP group had significantly higher prevalence of PDR 6, traction retinal detachment involving macula, postoperative retinal detachment, postoperative vitreous hemorrhage, postopera-tive neovascular glaucoma and reoperation (P value was 0.042, 0.048, 0.048, 0.000, 0.000, 0.000, respectively). Conclusion Risk factors of light perception and no light perception after vitrectomy for PDR include PDR stage 6, traction retinal detachment involving macula, postoperative retinal detachment, postoperative, vitreous hemorrhage, postoperative neovascular glaucoma and re-operation.
