Currently, sixty-five original sprinkle drug products are available in various dosage forms including tablets, powders, granules, immediate-release capsules, extended-release capsules, delayed-release capsules, and multiparticulate drug delivery systems. By sprinkling on soft food vehicles, these products provide dosing flexibility and convenience of administration, which potentially improve the compliance of patients with *** to these advantages, the growth of sprinkle products picked up since the 1990s, and several regulatory issues regarding this dosage form have been raised and *** this article, the types of sprinkle formulations were discussed by dividing them into seven categories, and the commercial products were summarized in terms of the drug substance, pharmaceutical excipients, storage conditions and administration methods. In addition, several US Food and Drug Administration guidelines related to the regulatory issues of sprinkle formulations were reviewed, which led to the conclusion that the future development of this promising dosage form demands integrated guidance for industry rather than scattered information in various documents.

Gastric cancer(GC)is a pervasive global malignancy with high mortality rates due to distant metastasis[1].GC metastasis can occur via hematogenous route,peri-toneal route,and specifically through ovarian spread in females[2].Among these,peritoneal metastasis is the most prevalent and challenging condition to treat[3].The Cancer Genome Atlas(TCGA)has uncovered four molec-ular subtypes of GC:microsatellite instability,Epstein-Barr virus-related,chromosomal instability,and genomically stable[4].

Bi2Te3-based materials have drawn much attention from the thermoelectric community due to their excellent thermoelectric performance near room ***,the stability of existing n-type Bi2（Te,Se）3materials is still low due to the evaporation energy of Se (37.70 kJ mol-1) being much lower than that of Te (52.55 kJ mol-1).The evaporated Se from the material causes problems in interconnects of the module while degrading the efficiency.
