A method and system for automated quantitation of tissue micro-array image (TMA) digital analysis. The method and system automatically analyze a digital image of a TMA with plural TMA cores created using a needle to biopsy or other techniques to create standard histologic sections and placing the resulting needle cores into TMA. The automated analysis allows a medical conclusion such as a medical diagnosis or medical prognosis (e.g., for a human cancer) to be automatically determined. The method and system provides reliable automatic TMA core gridding and automated TMA core boundary detection including detection of overlapping or touching TMA cores on a grid.

A method for generating and analyzing an overview contrast image of a specimen carrier and / or of specimens situated on a specimen carrier. A specimen carrier arranged at least partially in the focus of a detection optical unit is illuminated in transmitted light using a two-dimensional, array-like illumination pattern. At least two overview raw images are detected using different illuminations of the specimen carrier, and, according to information to be extracted from the overview contrast image, a combination algorithm is selected by means of which the at least two overview raw images are combined to form the overview contrast image. According to information to be extracted from the overview contrast image, an image evaluation algorithm is selected by means of which the information is extracted.

The invention relates to a hemolytic agent for blood leukocyte five-classification counting and an application thereof. The hemolytic agent comprises a hemolytic agent A and a hemolytic agent B. The hemolytic agent A comprises a polyoxyethylene nonionic surfactant, an organic acid, a quaternary ammonium salt cationic surfactant cosolvent, a stabilizing agent and an osmotic regulator; the hemolytic agent B comprises alkaline inorganic salt and an osmotic regulator. When compared with the result detected by a standard hemolytic agent produced by BeckmanCoulter company, the hemolytic agent of the invention has good correlation and high accuracy. Especially, when abnormal cells exist in a blood specimen, the hemolytic agent has high warning sensitivity and good specificity, and exhibits the most beneficial effect.

The invention discloses a paper-based micro-flow switch controlled by surface acoustic wave; surface acoustic wave which is excited by an interdigital transducer is used for radiating micro-droplets on a drainage layer, so that the micro-droplets deform and become higher; after becoming higher, the micro-droplets are contacted with the bottommost end of an unfolded part of a folded paper-based micro channel and are absorbed by the folded paper-based micro channel; the micro-droplets are conveyed in the folded paper-based micro channel; when the micro-droplets are conveyed to a folded corner of the folded paper-based micro channel, the folded corner is increased, so that the height of the folded paper-based micro channel is changed, a first folded part of the folded part of the folded paper-based micro channel is connected with a first paper-based micro channel and a second paper-based micro channel, and micro fluid in the first paper-based micro channel passes through the first folded part of the folded part and flows into the second paper-based micro channel. The method for controlling the on and the off of the paper-based micro-flow switch through the changes of the height of the micro-droplets conveniently realizes the programmability of the paper-based micro-flow switch, and simultaneously greatly expands the scope of application of a piezoelectric micro-flow control chip.

The invention discloses a method for analyzing unified log data. The unified log script can be used in the website system to generate a unified log data set, which can be generated uniformly according to the requirements of the unified log script, so as to facilitate automatic analysis of the log data. First, group the unified log data in the unified log data set according to the user ID and log type. For multiple unified log data in the same group, the complete operation track of the same user can be obtained through the combination of function points, so as to realize the business tracking of users. For multiple unified log data in the same group, by comparing the time-consuming time of each function point, the function point whose time-consuming time exceeds the threshold is determined to realize the performance analysis of the function point. For multiple unified log data in the same group, the usage frequency of each function point is counted to realize the hotspot analysis of the function point, and the correlation analysis of the business is realized by counting the front and rear functions of each function point.

The invention provides compositions and methods useful in the analysis of tissues and cells. More specifically, the invention provides compositions, referred to as “pseudo-tissue samples,” which comprise aggregated fixed cells embedded in an embedding medium. The invention also provides histological specimens comprising pseudo-tissues, as well as histological specimen-substrate compositions, such as microscope slides upon which pseudo-tissues and histological specimens prepared therefrom are placed. The histological specimen-substrate compositions may comprise arrays (or microarrays) of pseudo-tissues and / or histological specimens. The invention also provides methods for preparing pseudo-tissues, histological specimens, and histological specimen-substrate compositions containing the same. Also provided is a method for analyzing a tissue sample by comparing the subcellular features of a reference histological specimen to those found in a candidate histological specimen, such that one or more subcellular features shared by both the candidate and reference histological specimens may be identified. The subcellular features that may be identified include, e.g., DNA, RNA, proteins, enzymes and carbohydrates.
