Abstract: A method for removing stale context in a service instance, comprising: generating a user message according to UID and request instruction of received request data; routing the user message to first service instance; if target context corresponding to the user ID is saved in a global cache of a database, loading the target context from the global cache: when the loaded target context does not belong to the first service instance, setting the loaded target context to belong to the first service instance, wherein the set target context is saved into a first local cache and the global cache; and instructing to remove one or more invalid target contexts corresponding to the user ID from one or more other service instances, wherein the invalid target contexts are target contexts which do not belong to the first service instance, such that stale contexts which are the invalid target context are removed.

Abstract: The present application discloses a primer set, a reagent, a kit for detecting methylation of a specific region of a human colorectal cancer-related gene from feces, blood, or tissue by using specific PCR, and the application thereof. The primer set includes specific amplified primer probe sequences for the methylated regions of specific regions of the gene markers PRDM12, FOXE1, and B3GAT2 genes found in this study; and the primer probe group also includes the specific amplification primer probe sequence of the methylated region of the specific region of the Vimentin, SFRP2-1, and SFRP2-2 genes and the specific amplification primer probe group of the internal reference gene ACTB, thus having high detection efficiency and strong pertinence.

Abstract: A filtering and ventilating mechanism is driven by motors. The filtering mechanism rotates and presses downwards so its pressing surface is against a sample container. A ventilation needle is inserted into the sample container for ventilation. A mixing mechanism is arranged below the filtering mechanism and is driven by a mixing motor. The sample container is accommodated in a seat and is driven by the mixing motor. A test tube carrying mechanism is arranged below the mixing mechanism, and has an accommodating hole for a test tube. A jacking mechanism is arranged below the mixing mechanism, and is driven by a jacking motor. When the jacking mechanism moves upwards, a jacking platform is pressed against the bottom of the test tube, so that the test tube is butted against the bottom of the sample container, and a sample preparation in the sample container is dripped into the test tube.

Abstract: Systems and methods which provide an adaptive unified performance management (AUPM) framework for interacting with disparate network elements using techniques adaptive to operational conditions to provide network performance adaptive root cause analysis (ARCA) are shown. An AUPM framework of embodiments of the invention implements a proxy based architecture in which a plurality of proxies are utilized to connect to and perform data communication with the disparate network elements. Centralized performance management is in communication with the proxies to obtain and unify network element data for performance monitoring, alarm reporting, and/or root cause analysis. The performance monitoring, alarm reporting, and root cause analysis provided by centralized performance management of embodiments herein implements adaptive cluster-based analysis to provide robust operation adapted to accommodate various operational scenarios, such as may include time varying conditions and learning based configuration.

Abstract: A bottom control type specimen filtering container consists of a seal plug (1), a top cap (2), a cylinder body (3), a piston rod (5), pistons (6), a clutch spring (7), a drainage needle (8) and a bottom cap (9). The piston rod (5) is disposed in a central hole (12) at the bottom of the cylinder body (3). The pistons (6) are tightly sleeved on the projections of the piston rod (5). The drainage needle (8) is fixedly connected to the lower end of the piston rod (5) through screw thread. One end of the clutch spring (7) is pressed against the bottom of the cylinder body (3), and the other end is against a flange of the drainage needle (8). Furthermore, a double-layer filtering system composed of a first layer of filter screen (4) and a second layer of filter screen (11) is arranged in the specimen filtering container. The shaft of the first layer of filter screen (4) penetrates through a middle hole of the second layer of filter screen (11) and is fixed in a hole at the top of the piston rod (5).
