A Schistosoma haematobium recombinant fusion protein ShSAP and an application thereof in the immunodiagnosis of schistosomiasis. The Schistosoma haematobium recombinant fusion protein ShSAP can undergo large-scale standardized mass production by means of genetic engineering technology, antigen quality is stable and the repeatability of the results is good. The fusion protein can be used for the immunodiagnosis of both schistosomiasis haematosis and schistosomiasis mansoni, and has extremely high sensitivity. The Schistosoma haematobium recombinant fusion protein ShSAP has a single antigen component, and ShSAP-ELISA has excellent specificity for the immunodiagnosis of schistosomiasis. The fusion protein does not cross-react with the serum of a patient suffering from another parasitic disease, and has broad application prospects.

Abrégé
Provided is an application of Cas13a in antagonizing viruses. The Cas13a is any one selected from Leptotrichia buccalis, Listeria seeligeri, Leptotrichia shahii, and Leptotrichia wadei CRISPR systems. The virus is one or more of a human DNA virus, RNA virus, or retrovirus. By using a Cas13a gene-editing technology of having high RNase activity to inhibit the life cycle of three different types of viruses (DNA virus, RNA virus, and retrovirus) in the cell, the result exhibits higher RNA cleavage activity and a broader range of applications.
A potent HIV inhibiting lipopeptide, a derivative thereof, a pharmaceutical composition thereof and use thereof. The lipopeptide is as follows: a) the lipopeptide is formed by connecting a polypeptide having antiviral activity to a lipophilic compound which is linked to a carboxy-terminal of the polypeptide, or b) the lipopeptide is formed by connecting a polypeptide having antiviral activity to a terminal protecting group and a lipophilic compound which is linked to a carboxy-terminal of the polypeptide, wherein the terminal protecting group is an amino terminal protecting group and/or a carboxy-terminal protecting group; the polypeptide sequence consists of 28 amino acid residues, corresponding to the 127th-154th amino acids in the HIV-1 strain HXB2 gp41 sequence. Compared with T-20, the anti-HIV activity of the lipopeptide is several thousands times or even tens of thousands times higher, and is also significantly higher than that of anti-HIV lipopeptides C34-Chol, LP-19, and the like.

The present invention provides a method for detecting human papillomavirus genotypes, wherein each of the genotypes is detected by dual probes for oncogenic early transcription region E6 or E7 gene segment and late transcription region L1 or L2 gene segment of capsid protein. The method is for detection and/or identification of human papillomavirus (HPV) genotypes, with elimination of PCR amplifying product contamination as the prerequisite, identification of genotype with dual gene probes as the foundation, and PCR coupled with mass spectroscopy as the platform.
