Abstract: A big data-based intelligent algorithm for an intraoral prosthesis design scheme establishes an intraoral prosthesis design scheme database based on predetermined data of partially edentulous jaw, and is configured to conduct an accurate search for data of partially edentulous jaw to obtain a recommendation list of an accurate theme and a corresponding design scheme for an intraoral prosthesis design, or conduct a fuzzy search for data of partially edentulous jaw to obtain a recommendation list of a fuzzy theme and a corresponding design scheme for an intraoral prosthesis design. When oriented to a digital design of a removable partial denture, the intelligent system for the intraoral prosthesis design scheme constructed based on this intelligent algorithm displays a large number of intraoral prosthesis design schemes of different design themes to dental technicians in a three-dimensional manner.

Abstract: A Bacillus altitudinis ST15 antagonizing Xanthomonas oryzae and use thereof, the Bacillus altitudinis ST15 was deposited in China General Microbiological Culture Collection Center on Jun. 28, 2020 and has the deposit number of CGMCC No. 20156. The Bacillus altitudinis has a relatively high antagonistic activity to Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola, can promote growth of rice and improve a drought resistance of a rice seedling, and has a relatively strong tolerance to common chemical microbicides for controlling bacterial diseases of rice. A bacterial suspension or a biocontrol inoculant prepared from this strain has a relatively high biocontrol effect on bacterial blight of rice and bacterial leaf streak of rice, can replace or reduce chemical pesticides, improves safety of food and ecological environment, and has relatively high economic and social benefits.

Abstract: Surgical access ports useful in minimally invasive surgical procedures are provided. The access ports comprise a cannula that defines a passageway for one or more surgical instruments through a tissue tract and a dome extending from the cannula to provide an expanded diameter for receiving one or more surgical instruments.

Abstract: Instrument docking ports and gas valve docking ports for sealingly engaging surgical access ports for use in transendoscopic and laparoscopic surgical procedures. The instrument docking ports comprise a cannula that defines a passageway for a surgical instrument, a rim outwardly extending around the circumference of the receiving end of the cannula that cooperates with one or more retaining protrusions outwardly extending about the external surface of the cannula to maintain the position of the cannula when installed for use. Disposed within the cannula is at least one sealing disc to allow insertion of a surgical instrument therethrough. The sealing disc sealingly engages with the surgical instrument when inserted and returns to a closed position when the surgical instrument is removed. The gas valve docking port has a gas ingress port and a gas egress port for controllable insufflation and desufflation of a target body cavity during a surgical procedure.

Abstract: A multifunctional check valve device contains: a base, an elastic member, and a locking member. The base includes a peripheral rib, an accommodating chamber, a column, a stopping face, a connecting orifice, a plurality of through orifices, a first outlet, and a positioning groove. The elastic member includes a fixing loop for retaining with the connecting orifice and a closing disc for corresponding to a second outlet of a pull-out faucet. An outer diameter of the closing disc is greater than an inner diameter of the closing disc, so the closing disc closes an inner face of an exit. The closing disc has a retaining tab for retaining with the positioning groove. The hollow locking member includes inner threads for screwing with outer threads of the pull-out faucet and accommodates the base. The hollow locking member also includes a third outlet for aligning with the first outlet of the base.
