  • Publication number: 20130295579
    Abstract: A method for preparing induced pluripotent stem (iPS) cells, which comprises steps as follows: step 1, introducing one or more stem cell pluripotency factors into somatic cells; step 2, culturing the somatic cells, into which the stem cell pluripotency factor has been introduced in the Step 1, by using medium supplemented with lithium salt; and step 3, identifying and characterizing the induced pluripotent stem cells. Furthermore, there provided a medium for preparing induced pluripotent stem cells, which comprising lithium salt. The medium supplemented with lithium salt is used for efficiently inducing pluripotent stem cells. Lithium salt is able to increase the production efficiency of mouse iPS cells by 5-60 times. The present method for inducing iPS cells is in favor of improving the safety of iPS technique and application of iPS cells in regenerative medicine.

  • Publication number: 20120101988
    Abstract: The present invention discloses a method for implementing management of application information in a mobile phone and an application manager, wherein, the method includes: after the mobile phone is powered on, its application manager reading application information from a file system and caching the application information in background. In the present invention, when the user starts up the application manager, the cached application information can be directly read and displayed, and does not need to be loaded from the file system, thus greatly improving the speed of displaying the application information, and thereby greatly enhancing the user's experience. In addition, when the user updates the application and inserts a memory card into the mobile phone, the information is synchronously updated in background by the application manager to be provided to the user for obtaining and displaying at any time.

  • Publication number: 20110167041
    Abstract: A method and device for maintaining a changelog in data synchronization are provided in the present invention, in which the changelog is configured to record an operation executed for an object and is composed of data record items. The data record item includes flag information configured to uniquely identify an object and an operation type corresponding to the flag information, the operation type includes adding, updating and deleting. The method includes: reading, between two times of the data synchronization, flag information of a first data record item which is required to be added to the changelog; searching for whether there is a second data record item including the flag information in the changelog, and in a situation that there is the second data record item, setting the second data record item according to the first data record item. By the present invention, the changelog file can be prevented from continuously increasing.
