Abstract: IgG epitope and applications thereof as a target are provided. The IgG epitope is the CH1 domain of non-B cell-derived IgG, and there is N-glycosylated sialic acid modification at the Asn162 site of the domain. The realization of its antigen functions must depend on the sialylation of the site. The present invention further discloses the applications of the IgG epitope as a drug target in preparing drugs for diagnosis and/or treatment of epithelial tumors. In addition, our studies showed that this antigen depends on the sialylation of Asn162 site as a drug target, and the sialylation of this site must depend on sialyltransferase ST3GAL4, indicating that the enzyme can be used as a drug target for preparing tumor therapeutic drugs. Further, integrin ?4 is co-expressed and co-localized with IgG containing the epitope. IgG can be used as a marker for preparing drugs for the auxiliary detection of epithelial tumors.

Abstract: Disclosed by present disclosure are a Darlington transistor drive circuit, a Darlington transistor drive method and a switching power supply management chip. In this embodiment, the Darlington transistor is driven sectionally. At the beginning of the switching-on cycle, the driving of the primary transistor is not started temporarily, instead the drive source is used to drive the secondary transistor. After the secondary transistor is completely switched on, the drive source of the secondary transistor is switched off and the drive source of the primary transistor is switched on to drive the Darlington transistor. The primary and secondary transistor have been completely switched on, and the drive current of the secondary transistor never depend on the primary transistor, so the voltage at the input terminal of the secondary transistor can be smaller than the voltage at the control terminal of the secondary transistor. Such that the switching-on power loss is reduced.
