The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.

除了对各个电子传递体（ FAD ，[2Fe-2S]，[4Fe-4S]，[3Fe-4S]以及血红素分子）进行精确定位外，我们在该结构跨膜区靠近线粒体基质一端的口袋 Qp 中，发现了一些电子密度，认为是所结合的辅酶 Q 的头部结构，这一点被与抑制剂结合的复合体的结构所证明，在该结构中， 2－ TTFA 恰好结合在口袋 Qp 中，同时，我们还发现了第二个2－ TTFA 的结合位点，位于跨膜区靠近线粒体膜间隙一端的口袋 Qd 中，这个发现具有全新的意义，将影响人们对电子在复合物 II 中传递以及辅酶 Q 在复合物 II 与 III 之间转移的认识，促使人们重新复合物 II 在线粒体呼吸链中的角色。

To confirm the hypothesis that the pathogenic mechanism of air infusion in the circulatory system is not bubble blockade of blood vessels but the consequence of anoxia of the vital organs,different amounts of air were injected into the great sapenous vein of 22 dogs,and then heart rate,cardiac rhythm and bubble sound were monitored with a Doppler probe at the precordial region.

为探讨循环系统内注入空气致病机理，向22只狗大隐静脉内注入不等量空气并在心前区用Doppler监测心率、心律和气泡音。结果发现，维持心前区Ⅳ级气泡音的17只狗，依次出现呼吸和心率加快、心律紊乱、心率缓慢、腹式呼吸加强，其中12只狗继续缓慢注入空气至呼吸停止，任选10只狗胸外按压，8只狗复苏后行为无异常，2只狗未能复活。另2只狗呼吸停止后立即尸检，可见右心房、室、腔静脉和肺血管中有大量气泡。

Results: 22 cases of inflammatory pseudotumor, and all the dissociated edges being sharp, including 9 cases involving tear gland, 7 cases surrounding the eyeball, 2 cases showing the optic nerve and extraocular muscles thicken, and 4 cases showing several extraocular muscles diffuse thicken. 4 cases were granulomatous inflammation filling up the orbit with soft tissue. One case was the chronic inflammation of the lacrimal sac showing a cystoid lump in the area of the lacrimal sac. One case was the chronic inflammation around the lacrimal sac showing a small lump with a low denstiy in its center in the area of the lacrimal sac. One case was orbital cellulitis showing the density of the right part in the orbit outside the eyeball becoming higher, and having not a edge.
