0.05). In 30 eyes of diabetics with phacoemulsification, 11 eyes had new macula edema after surgery and 3 eyes had significant retinal thickening. In 6 eyes with macular edema before surgery, the macular edema were aggravated in 3 eyes after surgery. The macular structural changes were not found in two control groups. Conclusion The thickness of retina is inreased after phacoemulsification in deabetics,and morbidity and its severity of postopevative macular edema are increased as well.

Objective To observe the changes of macula in patients with high myopia after phacoemulsification. Methods In 20 patients with high myopia with ocular axial length≥27 mm, optical coherence tomography (OCT) was performed on the operative and contralateral eyes 1 week before and after monocular phacoemulsification, respectively, and the OCT images of macula of the operative eyes were observed and compared. Results One week before and after phacoemulsification, the mean macular fovea thickness of the patients with high myopia was (131.6?16.37) ?m and (189.75?45.69) ?m, respectively, with a significant difference (t=2.805, P=0.01). Simultaneously, the mean macular fovea thickness of the contralateral eyes was (133.5?15.12) ?m and (133.5?14.63) ?m, respectively, with a non-significant difference (t=1.367, P=0.853). In 20 operative eyes 1 week after phacoemulsification, 3 had vitreous strand around the macula with retinal thickening, 1 had retinoschisis in macular area, and 2 had obvious retinal thickening with slight retinal edema. Conclusion Retinal thickening occurs in the patients with high myopia after phacoemulsification. Traction of retina by vitreous strand or subclinical retinoschisis may occur in some patients.

In order to understand the research status of HUANG Fu-mi's A-B Classic of Acupuncture and Moxibustion, 83 pieces of literature that have been publically published since 1978 were analyzed. A summary was performed according to 7 aspects including version origin, emendation, arrangement and summary, theory discussion, clinical research, value evaluation, the rest questions, etc. It is believed that deep research work has been done on explanations, emendation and translation regarding A-B Classic of Acupuncture and Moxibustion. However, the exploration work on the theory and application is far from enough. Therefore, beginning from historical and cultural background, we should analyze the humanistic spirit of HUANG Fu-mi combined with A-B Classic of Acupuncture and Moxibustion to perform a deep exploration, so we could have a thorough and comprehensive research on HUANG Fu-mi's academic thoughts.

Uveitis is a group of inflammatory diseases causing serious impairment of visual function. The precise etiology and pathogenesis remain unclear. lt can be induced by infection, trauma, tumor or autoimmune response, of which autoimmune response is the most common. ln recent years, the cytokines in the process of inflammatory autoimmune diseases role has become one of research hot spots, its role in the pathogenesis and the relationship between the disease activity more and more attention. This article reviews the effects of interleukin, tumor necrosis factor, interferon and transforming growth factor-β in the pathogenesis of uveitis.

OBJECTIVE: To investigate short-term and long-term efficacy of PGLA thread-embedding therapy in the treatment of stage Ⅰ post-stroke shoulder-hand syndrome. METHODS: A total of 60 patients with stage Ⅰ post-stroke shoulder-hand syndrome were randomly divided into control group and treatment group, with 30 patients in each group. The patients in the control group were given acupuncture combined with rehabilitation training, and those in the treatment group were given PGLA thread-embedding therapy combined with rehabilitation training. Conventional acupuncture was performed once a day, and thread-embedding therapy was performed once every 5 days. Both groups were treated for 30 days. Clinical outcome, Visual Analogue Scale (VAS) score, hand edema score, and Fugl-Meyer Assessment (FMA) score were compared within and between groups immediately and at 1 month after treatment. RESULTS: The treatment group had a significantly higher overall response rate than the control group immediately and at 1 month after treatment (93.33%/86.67% vs 73.33%/56.67%, P<0.05). Both groups had significant reductions in VAS score and hand edema score and a significant increase in FMA score immediately and at 1 month after treatment (P<0.05), and the treatment group had significantly greater improvements than the control group (P<0.05). CONCLUSION: PGLA thread-embedding therapy has a better clinical effect than conventional acupuncture in the treatment of stage Ⅰ post-stroke shoulder-hand syndrome.

To investigate the problem and solution strategy of the clinical medical education of foreign students by applying the simulation teaching in Ob/Gyn clinical clerkship of foreign students. It demonstrates that combing the simulation teaching for diagnosis and treatment with the heuristic teaching can help the student overcome language barrier, the lack of basic theoretical knowledge and shortage of clinical teaching resources and it's of great significance in clinical medical education of foreign students.

The aim of this study was to propose an algorithm for three-dimensional projection onto convex sets (3D POCS) to achieve super resolution reconstruction of 3D lung computer tomography (CT) images, and to introduce multi-resolution mixed display mode to make 3D visualization of pulmonary nodules. Firstly, we built the low resolution 3D images which have spatial displacement in sub pixel level between each other and generate the reference image. Then, we mapped the low resolution images into the high resolution reference image using 3D motion estimation and revised the reference image based on the consistency constraint convex sets to reconstruct the 3D high resolution images iteratively. Finally, we displayed the different resolution images simultaneously. We then estimated the performance of provided method on 5 image sets and compared them with those of 3 interpolation reconstruction methods. The experiments showed that the performance of 3D POCS algorithm was better than that of 3 interpolation reconstruction methods in two aspects, i.e., subjective and objective aspects, and mixed display mode is suitable to the 3D visualization of high resolution of pulmonary nodules.
