Patent number: 11278542Abstract: The present disclosure provides a use of a nicotinamide composition in preparation of a drug for treating hand-foot skin reaction (HFSR) induced by sorafenib, the composition being consisted of nicotinamide and sorafenib in a dosage ratio of 2:3. The composition provided by the present disclosure can alleviate the HFSR caused by excessive keratinization induced by sorafenib. This protective effect is achieved by inhibiting HB-EGF/SIRT1 pathway. The present disclosure provides a mechanism of sorafenib-induced HFSR, i.e., the excessive activation of the HB-EGF/SIRT1 pathway, thereby providing a theoretical foundation for clinical research of sorafenib-induced HFSR. The present disclosure also provides a drug that can effectively treat sorafenib-induced HFSR, thereby greatly broadening the clinical application of sorafenib. Nicotinamide is highly clinically feasible due to its moderate price, and thus can be prepared in any suitable formulation according to the requirements.Type: GrantFiled: October 31, 2018Date of Patent: March 22, 2022Assignee: ZHEJIANG UNIVERSITYInventors: Qiaojun He, Bo Yang, Peihua Luo

Publication number: 20210390851Abstract: Disclosed is a device which incorporates a process by which an absorptive material is used to absorb fluid, the weight of said fluid causes the device to move without any outside energy source. The fluid, by way of evaporation or by being absorbed into another absorptive material, substantially disappears, causing the device to return back to its starting position on its own, and repeat the process. The fluid, which is stocked in a holding area, remains stagnant, until the device in its starting position is made in contact with the fluid by use of a counterweight, and thereby absorbs the fluid, however, when the device is saturated, the greater volume of absorbent on one side causes the device to move to its activated position. In its activated position, the device is not exposed to the fluid and therefore remains until the fluid is evaporated or absorbed into another absorbent.Type: ApplicationFiled: August 31, 2018Publication date: December 16, 2021Inventors: Jun GU, Qinggui PAN, Qiaojun HE, Lulong CAI, Ming FAN, Qian MAO, Yanlin LI
