Abstract: The present invention relates to the field of pharmaceutical and chemical engineering, and specifically relates to a weakly acidic microenvironment-sensitive aptamer for tumors, a triptolide conjugate. The conjugate is formed by conjugation between the 14-position hydroxyl group of triptolide and the aptamer via an acetal ester linking bond, which is an acid-sensitive linking bond with a cleavage condition of (pH=3.5-6.5), which is much less pH-sensitive and is more likely to cleave under the tumor microenvironment. Based on the characteristics of the aptamer targeting the highly expressed proteins on the membrane surface of tumor cells, the conjugate delivered triptolide targeted to tumor cells and mediated endocytosis to reach the lysosome; based on the characteristics of the acidic environment of lysosomes, the acetal ester linking bond released intact triptolide in the lysosomal acidic environment, targeting and killing of tumor cells.

The DC converting units are respectively adapted to couple to an AC power source to convert the AC power source to two first DC power sources and changes a voltage of each of the first power sources according to different voltage of the AC power source. The physical wiring and controlling unit is connected to the outputs of the DC converting units and the signal detecting unit and automatically connects the outputs of the PFC circuits in parallel if a high line voltage range of the AC power source is coupled to the full bridge rectifier. On the contrary, the physical wiring and controlling unit automatically connects the outputs of the PFC circuits in serial. Accordingly, the universal input switching power supply has good transmitting efficiency at different AC power source conditions.
