["Houxi (SI 3) communicating the governor vessel" verified with the infrared thermal imaging technology].

Objective: To compare the effect on facial acupoint temperature between acupuncture at Houxi (SI 3) and Dazhui (GV 14) so as to verify "Houxi (SI 3) communicating the governor vessel" based on the infrared thermal imaging technology.

Methods: Thirty-five healthy subjects (5 cases dropped off) were collected and before-after study in the same subject was adopted. The subjects were successively assigned into a sham-acupuncture group, a Houxi group, a Wangu group and a Dazhui group.

Experimental Investigation on a Novel Polyelectrolyte Molecular Deposition Film for Improved Injectivity in Low-Permeability Reservoirs.

Acrylamide and dimethyl diallyl ammonium chloride were used as monomers to synthesize a polyelectrolyte molecular deposition film (PMDF) injection agent for solving the problem of high injection pressure of water wells in low-permeability reservoirs. The structure of the PMDF injection agent was determined through IR and H nuclear magnetic resonance (NMR). The performance evaluation results show a change of wettability from hydrophilic to neutral wetting with the contact angle changing from 22.

Fabrication and Application of a 3D-Printed Poly--Caprolactone Cage Scaffold for Bone Tissue Engineering.

Poly-ε-caprolactone (PCL) is a promising synthetic material in bone tissue engineering (BTE). Particularly, the introduction of rapid prototyping (RP) represents the possibility of manufacturing PCL scaffolds with customized appearances and structures. Bio-Oss is a natural bone mineral matrix with significant osteogenic effects; however, it has limitations in being constructed and maintained into specific shapes and sites.

Preliminary Clinical Application of Complete Workflow of Digitally Designed and Manufactured Sports Mouthguards.

Purpose: To establish a complete digital workflow for the design and manufacture of sports mouthguards and to observe preliminary clinical effects.

Materials And Methods: Eighteen healthy participants were included in this study. The self-controlled method was applied, and all participants were provided with two types of mouthguards.

Feasibility Study of Applying Modified Nano-SiO Hyperbranched Copolymers for Enhanced Oil Recovery in Low-Mid Permeability Reservoirs.

To improve oil recovery significantly in low-mid permeability reservoirs, a novel modified nano-SiO hyperbranched copolymer (HPBS), consisting of polyacrylamide as hydrophilic branched chains and modified nano-SiO as the core, was synthesized via an in situ free radical polymerization reaction. The structure and properties of the hyperbranched copolymer were characterized through a range of experiments, which showed that HBPS copolymers have better stability and enhanced oil recovery (EOR) capacity and also smaller hydrodynamic radius in comparison with hydrolyzed polyacrylamide (HPAM). The flooding experiments indicated that when a 1000 mg/L HPBS solution was injected, the resistance factor (RF) and residual resistance factor (RRF) increased after the injection.
