A method for treating a lesion of an animal, the animal having at least one vessel that carries blood to the lesion, comprising locating the vessel, administering a composition comprising a photodynamic agent, applying energy to the vessel to photocoagulate the vessel and thereby reduce the rate at which the treatment composition exits said lesion and applying energy to said lesion, of a type and an amount sufficient to excite the photodynamic agent, causing the lesion to undergo photodynamic therapy. Preferably, a dye that is both a fluorescent dye and a radiation absorbing dye, such as indocyanine green dye, is added to the treatment composition to allow (a) confirmation of the presence of the treatment composition in the lesion to be detected by fluorescent angiography and (b) the rate of blow flow to be reduced in the blood vessel feeding the lesion using dye enhanced photocoagulation.

The invention discloses a microcirculation pulse blood flow monitoring system and method used for liquid therapy and capacity management, and belongs to the technical field of medical treatment monitoring. The monitoring system comprises a data collecting module, a storage module and a comparison module. At different times, repeated positioning is conducted on blood capillaries in the same monitored region, and blood vessel image data is collected and stored; the measurement data of blood vessel images collected at different times are compared, the number of blood vessels where pulse blood flow occurs and/or the speed of pulse blood flow and/or the frequency of pulse blood flow occurrence are used as indexes for making capacity management and liquid therapy accurate, and the problem is solved that liquid therapy and capacity management lack clinical golden indexes. Through the monitoring system, a heart failure, pulmonary edema and tissue edema of lungs caused by excessive transfusionare avoided, the burden of kidneys is reduced, transfusion time is shortened, treatment costs are lowered, and the pains of patients are relieved.

The invention discloses a UHP tire for improving wetland performance. The UHP tire for improving wetland performance comprises a tread with the total length of a crown arc being TDW. Longitudinal maingrooves extending in the circumferential direction of the tire are formed in the tread, and pattern blocks extending in the circumferential direction of the tire are formed between the longitudinal main grooves. The relationship that TDW/SN is greater or equal to 0.80 and less than or equal to 0.82 exists between the total length TDW of the crown arc and the nominal section width SN of the tire,and the relationship that TP/TDW is greater than or equal to 0.047 and less than or equal to 0.049 exists between the total length TDW of the crown arc and the height difference TP between center point of the crown arc and the end point of the crown arc. Each pattern block is designed with a thickened convex surface, so that the grounding edges of the pattern blocks present a convex state, and thedefect of the concave faces of grounding edges of the pattern blocks caused by the contraction of the tire compound is overcome; and at the same time, the grounding edges with convex surfaces improvethe water breaking capacity of the tire, effectively avoid the water slip during wheel driving, and improve the use safety and stability of the tire.
