Publication number: 20240115627Abstract: The present disclosure relates to use of a Clostridium ghonii spore combined with pembrolizumab in cancer treatment. It is found for the first time that the Clostridium ghonii spore combined with pembrolizumab can significantly improve a curative effect of colon cancer and reduce a dose of the pembrolizumab, and thus is efficient and low-toxic. Oncolysis by Clostridium ghonii can affect immunogenicity of a tumor microenvironment (TME) by various ways, converts an immunosuppressive state of the TME into an immune-activated state, adjusts the immunosuppressive TME, and breaks an immune tolerance. An optimal combination of the Clostridium ghonii spore and the pembrolizumab thoroughly removes about 20% of mouse tumor tissues. A benefit range of patients with tumors treated by a PD-1 antibody is expanded. The combination even has an obvious curative effect on patients failed the treatment by the PD-1 antibody.Type: ApplicationFiled: October 9, 2022Publication date: April 11, 2024Inventors: Yong Wang, Hong Zhu, Wenhua Zhang, Yanqiu Xing, Dan Wang, Yuanyuan Liu, Shaopeng Wang, Jiahui Zheng, Rong Zhang, Xiaonan Li, Xinglu Xu, Shengbiao Jiang, Lichao Xing, Yuxia Gao, Shili Shao, Ting Han

Patent number: 11305456Abstract: A selective laser sintering (SLS) device. The SLS device includes a laser forming unit, a support platform and a driving mechanism. The support platform is configured to support a plurality of raw materials for additive manufacturing of an object including a plurality of sections. The laser forming unit is disposed on the support platform and is configured to lay powders on a surface of each section of the object and sinter the powders. The driving mechanism is disposed under the laser forming unit and includes a vertical driving mechanism and a horizontal driving mechanism. The vertical driving mechanism is connected to the laser forming unit and configured to lift the laser forming unit layer by layer. The horizontal driving mechanism is configured to drive the laser forming unit to move in a horizontal direction with respect to the support platform.Type: GrantFiled: October 16, 2019Date of Patent: April 19, 2022Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Yusheng Shi, Chunze Yan, Zhaoqing Li, Peng Chen, Zhufeng Liu, Jiamin Wu, Shifeng Wen, Chenhui Li, Lichao Zhang

Patent number: 10281473Abstract: The application discloses compositions, methods, systems, and apparatuses for rapid sequence analysis of proteins, including location of post-translational modifications and disulfide bonds. Limited digestion of fully denatured antibody occurs in seconds by flowing sample in 8M urea at constant pressure through a micro column reactor containing immobilized aspergillopepsin I, resulting in a product mixture containing 3-10 kDa peptides, which is then fractionated by capillary column chromatography and analyzed by both electron transfer dissociation (ETD) and collision activated dissociation mass spectrometry. This method provides 95% sequence coverage of a mAb and detects numerous post-translational modifications. For disulfide bond location, native mAb is subjected to longer digestion times. Release of disulfide containing peptides from accessible regions of the folded protein occurs with short digestion times.Type: GrantFiled: February 4, 2015Date of Patent: May 7, 2019Assignee: University of Virginia Patent FoundationInventors: Donald F. Hunt, Weihan Wang, Lichao Zhang
