Abstract: The present disclosure provides use of transferrin, a transferrin receptor and an antibody thereof in the preparation of an anti-SARS-CoV-2 drug. Use of the transferrin, the transferrin receptor or the transferrin receptor antibody in the preparation of an anti-SARS-CoV-2 drug is provided. Both surface plasmon resonance (SPR) and immunofluorescence confirm that the SARS-CoV-2 binds to the transferrin receptor through SARS-CoV-2 spike protein; the transferrin and/or the transferrin receptor antibody competitively bind(s) to the transferrin receptor of the body, or the transferrin receptor competitively binds to a site of the SARS-CoV-2 to inhibit binding of the SARS-CoV-2 to the transferrin receptor of the body; thus, the opportunity that the SARS-CoV-2 infects cells is blocked, and the antiviral effect of the body is realized.

Abstract: An agent for inhibiting binding of transferrin receptor to SARS-CoV-2 spike protein or an anti-SARS-CoV-2 medicament is provided, where active pharmaceutical ingredients of the agent or the medicament include interference peptides, and the interference peptides include: SL8, FG8, DL12, RK4, SD6, HF7, and/or QK8.

Abstract: The present disclosure provides use of a reagent for detecting an expression level of transferrin in the preparation of a diagnostic reagent or kit for a disease caused by imbalance of intestinal immune tolerance, and belongs to the technical field of medical molecular biology. In the present disclosure, the severity of intestinal inflammatory diseases is diagnosed according to the transferrin level, achieving the objective of the early diagnosis of the disease caused by imbalance of intestinal immune tolerance. In the present disclosure, the transferrin is used as a marker for imbalance of intestinal immune tolerance, featuring high specificity and sensitivity, and simple detection procedure.

Abstract: A method, system and device for active balance control of a battery pack are disclosed. The method includes: calculating a reference balance current ratio of a battery cell to a battery pack in each batch; calculating an actual balance current ratio of the battery cell to the battery pack at each moment in any batch; allowing the actual balance current ratio to track the reference balance current ratio of the corresponding batch in real time by executing a preset tracking algorithm; and performing balance control on the battery pack according to a tracking result. The system includes a first calculation module, a second calculation module, a tracking module, and a balance control module. The device includes a memory and a processor.

Abstract: Methods and Apparatuses are disclosed for removing a duplicated web page. An exemplary method may include acquiring a plurality of web pages of a predetermined type extracting a feature code of a current web page and a number of text characters contained in the current web page for each web page. The method may also include looking up a data table to determine whether the feature code is contained in the data table. If the feature code is contained in the data table, the method may further include reading a number of text characters of the web page in the data table corresponding to the feature code, and discarding the current web page when a difference between the read number of text characters and the extracted number of the text characters is within a range.
