The invention provides application of a lactic dehydrogenase inhibitor in preparation of a medicine for preventing and / or treating aneurysm. The lactic dehydrogenase inhibitor is selected from a compound shown as a formula I in the specification or pharmaceutically acceptable salt thereof. Experiments show that the lactic dehydrogenase inhibitor can specifically inhibit synthesis of lactic acid in thoracic aortic aneurysm, recover expression of systolic genes, significantly inhibit vascular inflammation, maintain the systolic state of vascular smooth muscle cells and delay progress of thoracic aortic aneurysm. In addition, the lactic dehydrogenase inhibitor can also show a remarkable effect of inhibiting vasodilatation in thoracic aortic aneurysm mice, and has no remarkable influence on normal C57BL / 6J mice, so that the lactic dehydrogenase inhibitor is proved to have targeting and specific effects on thoracic aortic aneurysm. The lactic dehydrogenase inhibitor can also significantly inhibit vascular wall inflammatory response and elastic fiber destruction and delay the progress of thoracic aortic aneurysm by recovering the steady state function of vascular smooth muscle cells.

A conduit 101 is provided inside the catheter portion. The balloon portion is provided at one end of the catheter portion. A gas injection tube is inserted inside the conduit and extends to an interior of at least one gas injection air bag 202, and at least one blood flow path 201 is formed from one end to another end of the balloon portion. The gas injection tube injects gas into the balloon portion to inflate the balloon portion, and the balloon portion expands a blocked blood vessel by expansion. The gas injection tube injects gas into the balloon portion to open at least one blood flow path and bring it into communication with the blood vessel. By expanding the blood vessel using the catheter device, blood inside the blood vessel is continuously circulated through at least one blood flow path.SELECTED DRAWING: Figure 1

The invention is, inter alia, an electrically powered heating pad / rod / probe / cubic that utilizes variously-sized probe tips (geometric shaped substantially-solid “elements,”“rods,”“cubics” or “probes,” which are versatile and effective in poking / massaging different parts of the human body. The apparatus device and system is intended for medical purposes, providing heat therapy for body surfaces. The probes are capable of maintaining an elevated temperature during use, substantially dependent on the body part and other sensory feedback. The invention is used, inter alia, for warming of desired parts of the human body in order to alleviate and manage body pain. The localized application of the heat causes the blood vessels in (and underneath) that area to dilate, enhancing perfusion to the targeted tissue. The system involves proper thermal poking / application of specially-tailored geometric-shaped heating rods (aka “probe heads, or “cubics”) which are securely covered with disposable covers [ideally cotton / polyester / spandex and amalgams thereof] disposable fabric] which allows good hygiene and sanitation during repeated use. The device's cubics are each equipped with a central-core resistive heating element; the device / system comprises an automatic shut off feature and protective alarm—&—circuitry to properly respond to overcurrent & overvoltage.
