This invention discloses a flexible container and its usage method, comprising a container body with piping fittings, a support assembly, and paddle blades; the support assembly includes a lifting plate, a base, and connecting supports; the lifting plate is fixed to the top of the container body, and the base is fixed to the bottom of the container body; the connecting supports are disposed inside the container body, with one end connected to the lifting plate and the other end inserted into or detached from the base; wherein, the connecting supports can rotate relative to the lifting plate and the base about the axis of the container body, and can also fold and extend along the axis of the container body; paddle blades are disposed on the connecting supports. Through the above-mentioned design, this invention can avoid the risk of the flexible container's membrane material being torn, scratched, or damaged by collision during transportation, installation, and transfer lifting, improving the container's structural stability and load-bearing capacity, and ensuring the integrity of the sterile environment inside the container.

The invention discloses a CHO (Chinese hamster ovary) cell and a suspension process method, which are characterized in that a stable high-expression cell strain is obtained by improving a target expression vector, and the protein expression quantity of 1g / L is realized. The improved CHO cell can be suitable for a WAVE wave bioreactor and serum-free culture, contamination is effectively prevented, interference of exogenous factors is reduced, the level of related impurities such as endotoxin in a cell expression product is reduced, the operation steps are simplified, the occupied culture space is reduced, meanwhile, the culture time is shortened, and the culture efficiency is improved. Therefore, the culture efficiency is improved, bacterial contamination is effectively prevented, the endotoxin level in the product is reduced, and the production cycle is greatly shortened.

The utility model relates to the field of sterilization instrument boxes, and discloses a sterilization instrument box for root canal therapy, which comprises a box body, a box cover is clamped on the inner wall of the upper side of the box body, a limiting seat is fixedly connected on the inner wall of the upper side of the box body, a sliding groove is arranged on the inner wall of the upper side of the box body, a fixing rod is fixedly connected on the inner wall of the upper part of the box body, and the fixing rod is fixedly connected with the box cover. A pressing plate is slidably connected to the outer wall of the fixing rod, a limiting rod is elastically connected to the inner wall of the box body through a first spring, a guide block is fixedly connected to the outer wall of the limiting rod, a ruler groove is formed in the inner wall of the upper portion of the box body, and a containing assembly is arranged on the inner wall of the upper portion of the box body. According to the device, the pressing plate, the limiting seat, the limiting rod and the like are arranged, the limiting seat is used for separating instruments, then the pressing plate is used for fixing the instruments, and the situation that the instruments are damaged due to mutual friction during transportation and are polluted due to the fact that packaging bags are punctured by the instruments can be avoided.

The invention discloses a preparation capable of improving hair, preventing alopecia and promoting hair growth as well as a preparation method and a use method thereof, and belongs to the technical field of daily necessities. The preparation is a product obtained by mixing sliced ginger, Yunnan Baiyao powder, cacumen biotae, angelica sinensis and pseudo-ginseng powder and then soaking the mixture in Baijiu.
