The dialysis for three species of poplar stems apoplast was obtained by microdialysis method, and then the concentration of Na+, K+, Ca2+ in the dialysis sample was directly measured by graphite furnace atomic absorption spectrometry ( GF-AAS) . The flow rate of perfusate was 1μL/min and the cut-off molecular weight of probe was 30 kDa. The real-time and non-destructive test technique established for the detection of ion concentration could be applied in research of poplar biochemical physiology. The recovery of the proposed method was 95. 8%-103. 1%. The contents of sodium ion in Populus wutunensis, Populus simonii and Salix matsudana were 1034-1156 μg/L, 1493-1611 μg/L and 1586-1703 μg/L; potassium ion were 1012-1237 μg/L, 941-964 μg/L and 1095-1201 μg/L; calcium ion were 4976-5237 μg/L, 4786-5042 μg/L and 5893-6142 μg/L. The method could provide reliable data for the study of ion concentration changes of plant response to adapt to all kinds of external environment.

Abstract?AlM: To compare the in- the- bag lOL stability of different size of continuous curvilinear capsulorhexis ( CCC) in super high myopic eyes with cataract underwent phacoemulsification.?METHODS: A total of fourteen cataract patients with bilateral super high myopia were included, Phaco+lOL implantation were performed on both eyes, one eye was randomly classified into 5mm diameter CCC observation group, the fellow eye was 6mm diameter CCC observation group. Cataract extraction combined with in-the-bag intraocular lens implantation ( lOL ) with the type of hydrophilic acrylic aspheric intraocular lens ( MCX11 ) by well experienced surgeon. The operation was running smoothly, the next day after operation, all patients were confirmed by lmage-pro plus6. 0 image analysis software for the measurement of main meridian sac diameter with target capsulorhexis diameter no more than ±0. 2mm. Slit lamp examination of lOL shape and position, changes of anterior capculorhexis edge, refraction, anterior chamber depth was measured and observed of all eyes after operation 1wk;1, 3, 6mo.? RESULTS: Compared with postoperation 1wk, the former sac diameter of two groups were slightly smaller at postoperation 1mo, with no statistically significant difference between two groups. 5mm diameter CCC observation group had slightly hyperopic shift in follow-up 1-3mo, 6mm diameter CCC observation group had hyperopic shift in follow-up 1mo, and getting stable after 1mo. Refraction change was related to anterior chamber depth changes. 5mm diameter CCC observation group had 3 minor loop folding in follw-up 3mo.?CONCLUSlON:Relatively smaller continuous curvilinear capsulorhexis in super high myopic eyes underwent cataract surgery may cause a tendency of uneven construction or effective lens position change of in-the-bag lOL. Unusual refraction change or shift after operation 1mo could suggest instability of lOL, early noticing or interruption could prevent further complications.

Hirudin is one of the most potent anti-coagulant protein ever found, and its C-terminus is a key domain for inhibiting thrombin.In order to enhance its specificity,a novel anti-coagulant protein was constructed via fusing the C-terminus of hirudin to Annexin V, which was expected to sustain both anti coagulant activity and phorspholipid affinity. The structure of the designed protein was predicted with both molecular mechanics and dynamics. Molecular dynamics was adopted to simulate the docking interaction between the fusion protein and thrombin. The results showed the inhibitory activity of the fusion protein to thrombin.
