International Eye Science 2006;6(1):5-8
AIM: To investigate the association between cycloxygenase-2 (COX-2) expression and VEGF intervention as well as the inhibitory effect of Meloxicam on the cultured human pterygium fibroblasts (HPF).METHODS: Expression of COX-2 was measured by immunohistochemistry in the cultured HPF from twenty excised pterygium cases. Expression of COX-2 in HPF was measured by Western blot following the treatment of vascular endothelial growth factor (VEGF) at the different concentrations. In addition, the effect of Meloxicam on proliferation of HPF was studied by adding the different concentrations into the cultured HPF plates by Mono-nuclear cell direct cytotoxicity (MTT) reduction assay.RESULTS: COX-2 expression was present in the cultured HPF. The level of the expression increased following VEGF treatment. The proliferation of the cultured HPF decreased following addition of the different concentrations of Meloxicam (from 75μ mol/L to 300μ mol/L) and the magnitude of the inhibition was dose-time dependent.CONCLUSION: COX-2 levels in the cultured HPF werepositively associated with VEGF stimulation and Meloxicam was inhibitory to HPF proliferation.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9% in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1%, which were higher than 81.3% and 40.6% in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.
