Abstract: Provided is a method for machining micro-holes in a metal or alloy product which relates to the field of micro-hole machining. The method reduces the duration of ejection of primary plasma and the residuals produced during the ejection of the primary plasma, improves the smoothness of the hole wall of the micro-hole, and increases the depth limit of the micro-hole. Injecting energy by a low-energy pulse laser in two attempts further facilitates the reduction of the diameter of the micro-hole and reduces the possibility of cracks, compared with injection of the same energy by a single high-energy pulse laser. Moreover, a ratio between the diameter of the central ring of the ring spot formed by the focused second laser beam and the diameter of the central ring of the Gaussian spot formed by the focused first laser beam is greater than 1, which can improve the injection efficiency of laser energy.

Abstract: The present invention provides an application of lncRNAs ENST00000607393 siRNA in preparing a preparation for treating glaucoma. The present invention clarifies the correlation between the expression level of ENST00000607393 and the calcification of human primary trabecular meshwork cells. The expression level of ENST00000607393 in human primary trabecular meshwork cells is firstly down-regulated to 46.21% of a control group by siRNA interference. Under the condition of intervening with the cells by a 500 ?mol/L hydrogen peroxide solution for 48 hours, it is observed that compared with the control group, the down-regulation of ENST00000607393 expression can significantly decrease the ALP activity in human primary trabecular meshwork cells, and thus significantly decrease the calcification level of human primary trabecular meshwork cells to play a role of treating or preventing glaucoma.
