Abstract: A seat belt device includes: a latch plate including a snap-fit notch and configured to connect to an end part of a seat belt; a shell including a latch plate channel, the latch plate channel configured for the latch plate to extend into; and a locking piece. The locking piece includes two positioning plates and a locking plate connecting the two positioning plates. The locking piece is disposed on the shell between a locking position and a release position. The two positioning plates are sliding fit with the shell. When the locking piece is in the locking position and the latch plate extends into the latch plate channel, the locking plate is snap-fitted in the snap-fit notch, and when the locking piece is in the release position, the locking plate is configured to avoid the latch plate.

Abstract: Use of Cistanche deserticola polysaccharide (CDP) in promoting the proliferation and differentiation of female germline stem cells (FGSCs) is provided. Specifically, the addition of CDP in an in vitro cultivation system can promote the proliferation and differentiation of FGSCs, and especially can enhance the in vitro directed differentiation of FGSCs into oocytes, which provides a new research reference for studying the generation of oocytes in vivo and in vitro and also brings a new hope for research on physiological infertility.
