An elastic sheet for re-activating an endometrial basal layer in a uterine cavity comprises a silicone rubber and a drug, wherein the drug is encased inside the silicone rubber in the manner of a drug storage zone, or uniformly dispersed inside the silicone rubber, or carried by an outer surface of the silicone rubber as a coating, and the drug comprises an estrogen. A method for forming the elastic sheet with a drug in a matrix-type elastic sheet; or as a sustained release coating is provided. The estrogen is loaded on the silicone rubber, and thus the endometrial basal layer is continuously activated through drug stimulation, allowing for the endometrial basal layer to re-proliferate the functional layers, thereby restoring the normal endometrial structure and completely preventing adhesions.

Elastic sheet with function of re-activating endometrial basal layer in uterine cavity and forming method thereof

The present invention relates to a braiding method for a nasal sinus stent, comprising: providing a filament; providing a braiding tool having a longitudinal central axis, wherein the braiding tool comprises a first shaping part and a second shaping part which are axially spaced from each other, wherein the first shaping part is provided with n first anchor points, and the second shaping part is provided with n second anchor points; forming an initial configuration stent by around a circumferential direction of the braiding tool, allowing a single filament starting from 1st first anchor point on the first shaping part, coming across m1 vertex intervals to extend towards the second anchor point, and then coming across m2 vertex intervals to extend towards the first anchor point, so as to complete a first 'V' shaped braiding path, and then repeating the “V” shaped braiding path until the single filament returns to the 1st first anchor point, wherein the initial configuration stent has a circumference and n vertices with vertex interval obtained by dividing the circumference by n; m1 and m2 are integral multiples of 0.5, the sum of m1+m2 is an integer, and the sum of m1+m2 is not an integral multiple of a divisor of n. The sinus stent obtained by the above braiding method has good shape adaptability and is particularly suitable for being used as a self-expanding stent in the nasal cavity.

Weaving method for nasal sinus stent and stent obtained thereof

The present invention relates to a degradable vascular stent capable of avoiding late restenosis, comprising a base region formed by a polylactic acid based polymer; at least one storage region in which an active agent is stored; and an outer layer of a drug sustained release coating covered on the base region and/or the storage region. Before the mass of the polylactic acid based polymer is decreased by 10-20%, the active agent is retained in structural units of the polylactic acid based polymer. After the mass of the polylactic acid based polymer is decreased by 10-20%, the active agent is released from the storage region. The base region provides a supporting capacity for ensuring patency of blood vessels; the drug sustained release coating is used for drug release in an early stage; and the active agent only works in late degradation of the stent to avoid late restenosis.

The embodiments provide a cloud brainstorming service implemented on at least one cloud server. The brainstorming service includes a message service component configured to receive a plurality of ideas, over a network, from one or more users of devices. The users represent members of a brainstorming session. The brainstorming service also includes a brainstorming logic component configured to process the plurality of ideas and store the plurality of processed ideas in an in-memory database system, and a clustering component configured to retrieve the plurality of processed ideas from the in-memory database system and arrange the plurality of processed ideas into one or more clusters, where each cluster is a group of similar ideas. The message service component is configured to provide the plurality of processed ideas that are arranged into the one or more clusters, over the network, to the one or more users for display.

A request handler may receive transaction requests for transactions to be executed using data of a database, and may classify a first transaction request of the transaction requests as a simple transaction request, and a second transaction request of the transaction requests as a complex transaction request. A key-value store engine may execute a first transaction satisfying the first transaction request, using a key-value store of pre-calculated results determined prior to receipt of the first transaction request, and based on the data, and may update a key-value delta reflecting a change, if any, of the key-value store caused by the first transaction. A relational store engine may cause the at least one processor to execute a second transaction satisfying the second transaction request, using a relational store including a subset of the data, and may update a relational delta reflecting a change, if any, of the relational store caused by the second transaction. A synchronizer may execute a synchronization of the key-value store and the relational store, based on the key-value delta and the relational delta.

Concurrent request handling for database transactions

A computer system includes at least one processor and at least one memory operably coupled to the at least one processor. The memory includes a memory pool and a database partitioned into multiple fragments. Each of the fragments is allocated a block of memory from the memory pool and the fragments store compressed data in a columnar table format. A database operation is applied in a compressed format to the compressed data in at least one of the fragments.

Database operations on a columnar table database

A balloon system for treating sinusitis or allergic rhinitis includes a central inner tube, a balloon to be filled and a balloon catheter outer tube, all of which axially extend. The central inner tube includes a distal end part and a proximal end part detachably connected with each other by a connector in an axial direction. A first end of the balloon is connected to the distal end part, and a second end of the balloon and the balloon catheter outer tube are detachably connected with each other by the connector. The balloon catheter outer tube is radially outwardly spaced from the proximal end part, and the connector includes a first grommet and a second grommet rotating coaxially and relatively fixed with each other in axial direction. Each of the first grommet and second grommet has at least one gas port.

Balloon system for treating sinusitis or allergic rhinitis

A system includes a request analyzer configured to receive a plurality of database requests and classify the plurality of database requests as transaction requester or non-transaction requests, and further configured to route the transaction requests to a transaction server for application against a transaction database, including write access to an identified portion thereof, and to route the non-transaction requests to a non-transaction server to thereby read data obtained from a non-transaction database. The system also includes an update manager configured to update the non-transaction database, based on the application of the transaction requests against the transaction database.
