Publication number: 20200055950Abstract: An is provided for inhibiting the dissimilar expression of a PIWIL2 gene and a protein antibody against the dissimilar expression of the PIWIL2 gene in preparation of an anti-tumor drug. It has been experimentally proved that, treating human or mouse tumor cells with KAO3 upon inoculation can effectively inhibit the tumorigenesis in a mouse. Furthermore, injecting KAO3 into established lymphoma, breast cancer, lung cancer and cervical cancer can significantly inhibit tumor growth and prolong the survival of a tumor-bearing mouse. The inhibitory effect of KAO3 is associated with KAO3-specific antigens expressed on the surface of a tumor cell. KAO3 induces apoptosis of the tumor cell by blocking the cell cycle in a G2/M phase, inhibiting DNA synthesis and activating a complement. Therefore, the anti-PL2L60 mAb (KAO3) is a potential therapeutic candidate drug for treating a cancer.Type: ApplicationFiled: April 9, 2018Publication date: February 20, 2020Inventor: Jianxin Gao

Publication number: 20200055985Abstract: The present disclosure provides a production method of a semi-aromatic polyamide, and a semi-aromatic polyamide. Said production method of a semi-aromatic polyamide includes: step 1 of subjecting an initial charge of a diamine and a binary acid in an amine/acid molar ratio of less than 1.0 to form a slurry together with water and a catalyst, and subjecting the slurry to heating and dissolution to form a saline solution; step 2 of dehydrating said saline solution after detecting the composition thereof, detecting the content of diamine in a steam condensate from a dehydration unit, adjusting the amine/acid molar ratio to be larger than 1.0 by a molten diamine and a monoacid as a molecular weight regulator, and performing pre-polymerization; and step 3 of subjecting a pre-polymerization solution to post-polycondensation after vacuum flashing. The semi-aromatic polyamide of the present disclosure has a low gel content, excellent performance and extensive scope of application.Type: ApplicationFiled: June 29, 2017Publication date: February 20, 2020Inventors: Zhirong Chen, Hong Yin, Qin Zhang, Xiaoxiao Wu, Wengang Hong, Hangjun Deng, Guiyang Zhou, Changze Wang
