Background The early diagnosis and treatment is vital for the age-related macular degeneration (AMD).Previous examining methods were fundus fluorescein angiography(FFA)and optical coherence tomography (OCT).However,a new diagnostic technique,fundus autofluorescence(FAF),is applying in ophthalmology.objective This study was to observe the FAF characteristics of atrophic AMD. Methods Thirty-nine eyes of 28 patients with atrophic AMD were diagnosed and collected in our hospital and classified based on the criteria of Chen Song.FAF was performed by a confocal scanning laser ophthalmoscope(Heidelberg Retina Angiograph 2,HRA2).Characteristics of FAF images were compared with FFA images or color fundus photographs.Written informed consent was obtained from each patient prior to the examination. Results Areas with abnormal increased or decreased FAF signals were consisted or unconsisted with funduscopically visible alterations.Seven manifestations of FAF were found in the eyes with preatrophic stage of atrophic AMD,including slight change,focal increase pattern,patchy pattern,linear pattern,lacelike pattern,reticular pattern,and speckled pattern.In atrophic stage of atrophic AMD,geographic atrophy showed a well-defined hypoautofluorescence area;while non-geographic atrophy showed a ill-defined hypoautofluorescence area.There were three abnormal FAF patterns(focal,band and diffuse)in the junctional zone of geographic atrophy and diffuse pattern in the junctional zone of non-geographic atrophy. Conclusion FAF imaging is helpful for the diagnosis of atrophic AMD as a new non-invasive technique.

The changes of bioactive constituents were analyzed for Puhuang-Wulingzhi before and after compatibility and the antiplatelet and antithrombin activitives were evaluated in order to elucidate the scientific and reasonable of Puhuang-Wulingzhi compatibility. UPLC-QTOF-MA-Markerlynx, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis were used for data analysis and tracking changes of chemical composition during the decocting process. In vitro platelet aggregation induced by ADP, thrombin time(TT) and prothrombin time (PT) were investigated for Puhuang-Wulingzhi before and after compatibility. The results showed that significant differences were found between the mixed decoction and codecoction of Wulingzhi and Puhuang. Five compounds changed obviously were identified as typhaneoside, naringenin, isorhamnetin-3-O-ruinoside, quercetin-3-O-neohesperidoside, kaempferol-3-O-neohesperidoside. The codecoction, comparing with the single decoction, was more significant in antiplatelet aggregation and could prolong thrombin time. In the same crude drug dose, the thrombin time (TT) elongation were greater. These data could provide references for elucidation of bioactive components for this herb pair.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

Aim & methods The antagonism of L-dicentrine to contraction of isolated porcine coronary artery strips induced by 5-HT KCl and Ca2+ was observed with U-135 electrophsiological recorder.Results The contractions induced by 5-HT KCl and Ca2+ after high K+ depolarization in the strips of porcine coronary artery were markediy inhibited by L-dicentrine.L-dicentrine significantly depressed maximal response and caused rightward displacement of the dose -response curve. Showing a non-competitive antagonism. In Ca2+ free solution,L-dicentrine inhibited 5-HT-induced contraction of porcine coronary artery,which is dependent on Ca2+ relesed from intracellular store. After Ca2+ concentration in bath solution was restored,L-dicentrine did not influence the contraction of porcine coronary artery depending on extracellular Ca2+.Conclusion L-D have significant relaxation on porcine coronary artery ,which possibly has 5-HT receptor and histamine receptor.
