Abstract: Provided are a cra4S1 gene, an encoded cra4S1 protein, and a vaccine or drug containing the cra4S1 protein or a fragment thereof. A nucleotide sequence of the cra4S1 gene is represented by SEQ ID NO. 1. The vaccine combines the specific target of an outer membrane protein of Porphyromonas gingivalis and the antigen component of the bacterial conserved region, which has an immune prevention and protection effect on the body.

Abstract: The present invention relates to a thermosensitive label for monitoring the quality state of a thermosensitive article. The present invention also relates to a preparation method of the thermosensitive label and a thermosensitive article using the thermosensitive label. The thermosensitive label according to the present invention comprises two laminated layers which are physically-separated of a thermosensitive function layer and an adsorption-indication function layer. The two laminated layers are stored and transported separately, and combined together in use.

Abstract: The present invention relates to a time-temperature indicator for monitoring the quality state of a thermally sensitive article and a monitoring method. The present invention also relates to a preparation method of the time-temperature indicator and a thermally sensitive article using the time-temperature indicator. The time-temperature indicator according to the present invention comprises two laminated layers which are physically separated, i.e. a function indication layer and an adsorption function layer. The two laminated layers are stored and transported separately, and combined together in use. Therefore, the time-temperature indicator of the present invention can be stored and transported at room temperature, which reduces the usage costs of the time-temperature indicator.
