The invention relates to the technical field of pipeline joints, and discloses a high-sealing-performance insulating joint which comprises a connector, a sleeve cylinder, insulating filler and a U-shaped sealing ring, the sleeve cylinder is connected to the outer side of the connector in a sleeving mode, the space between the connector and the sleeve cylinder is filled with the insulating filler, the U-shaped sealing ring is arranged in the connector, a sealing stabilizing assembly is arranged in the connector, and the U-shaped sealing ring is connected with the U-shaped sealing ring in a sleeving mode. The sealing stabilizing assembly comprises an insulating plate which is arranged in the connector. A buffer is installed for a sealing system by sensing the internal pressure of a pipeline and dynamically adjusting the pressing state of the buffer plate set, initial sealing force is provided, meanwhile, the risk that a sealing piece is damaged due to pressure pulsation is reduced, and the sealing reliability of a connector under the complex working condition is fundamentally improved; through the negative pressure detection mechanism, operation and maintenance personnel can find faults in time and arrange maintenance in a planned mode, and economic losses and safety risks caused by leakage accidents and unplanned shutdown are avoided.

This invention belongs to the field of biomedicine and relates to a method for inducing fibroblasts to exhibit an immunosuppressive phenotype. Specifically, this invention relates to a method for inducing fibroblasts to exhibit an immunosuppressive phenotype, comprising the following steps: treating fibroblasts with (1) IFN-γ or (2) IFN-γ and rapamycin. This invention also relates to cell membrane vesicle nanoparticles and their uses. The cell membrane vesicles or cell membrane-encapsulated nanoparticles of this invention can effectively treat or prevent arthritis, especially rheumatoid arthritis, and have good application prospects.

The invention discloses a traditional Chinese medicine composition for relieving cough and a preparation method thereof. The composition is prepared from ephedra, almond, gypsum, perillaseed, thunberg fritillary bulb, white mulberry root-bark, cicada slough, radix stemonae, inula flower, clam shell, cynanchum glaucescens, tussilago farfara, schisandra chinensis, loquat leaf, perilla stem, tetrapanax papyriferus, indigo naturalis, semen raphani and liquorice according to a specific ratio. Aiming at the current situation that an existing cough-relieving traditional Chinese medicine prescription is insufficient in consideration of complex syndrome type cough and limited in curative effect, a synergistic compound is formed through combination of multiple methods such as lung freeing, heat clearing, phlegm reducing, qi depressing, spasmolysis and lung astringing, and the traditional Chinese medicine prescription is especially suitable for cough with phlegm-heat stagnating lung, lung dysfunction and descending and airway spasm syndrome.

The present application relates to a kind of typhoon can be released with platform's water isolation sleeve support system and its use method, wherein, typhoon can be released with platform's water isolation sleeve support system for supporting the water isolation sleeve of subsea well, subsea well is configured with deepwater self-elevating production platform around, the deepwater self-elevating production platform includes hull, the water isolation sleeve support system includes moving mechanism, bottom foundation and water isolation sleeve support frame, moving mechanism is set on the deck of hull;Bottom foundation is set to the sea bottom near deepwater self-elevating production platform;The bottom end of water isolation sleeve support frame is detachably connected on the bottom foundation, and the top end of water isolation sleeve support frame is connected with hull by moving mechanism.When typhoon is encountered, the moving mechanism releases water isolation sleeve support frame, realizes that water isolation sleeve support frame is quickly released from deepwater self-elevating production platform when typhoon is encountered;When deepwater self-elevating production platform moves or reinstallation, the moving mechanism will water isolation sleeve support frame be lifted to the deck of hull, realize that deepwater self-elevating production platform is moved together with water isolation sleeve support frame and reinstallation.
