Current gastroscopy practices necessitate a balance between procedural efficiency and patient safety. It has been hypothesized that increasing procedure outcomes through the use of Streptomyces protease enzyme and Shutai is possible; however, precise nature of any potential adverse reactions and complications remains unknown. In Zhanjiang, China, 213 patients undergoing gastroscopy participated in this controlled trial. The subjects were allocated at random into two groups: control and treatment. The treatment group was administered topical Streptomyces protease enzyme and intravenous Shutai. Using chi‐square and t‐tests, information regarding patient demographics, adverse reactions, wound healing, procedure duration, distress levels, and satisfaction was gathered and analysed. The demographic and medical history characteristics of the groups were comparable. There was a greater prevalence of modest immediate reactions in the treatment group (p < 0.05), whereas there were no significant variations observed in delayed reactions and long‐term complications (p > 0.05). The treatment group exhibited superior efficiency metrics, including shorter durations for diagnosis, procedure completion and recuperation (p < 0.05). The treatment group exhibited significantly higher patient satisfaction scores (p < 0.05). The incorporation of Streptomyces protease enzyme and Shutai into gastroscopy procedures resulted in significantly enhanced level of procedural efficacy and patient contentment while not introducing an additional risk of long‐term complications. The increase in moderate immediate reactions that have been observed requires additional research in order to determine their clinical significance. Although these agents present a possible progression in the field of gastroscopy, their application should be tempered by the immediate adverse reactions that have been documented.

When hydrogels are in environments with high water content, they usually undergo swelling, leading to a degradation of mechanical properties, which severely limits their application in underwater sensing. To solve this problem, we synthesized an anti-swelling, tough, double-crosslinked, dual-network hydrogel, P(AA-SMA)-CMC-Na, for underwater sensing. Due to the hydrophobic association and electrostatic interactions between the cationic surfactant N-Hexadecyltrimethylammonium chloride (CTAC) and poly (acrylate-methacrylate octadecyl ester) [P(AA-SMA)], as well as the dense network structure brought about by double cross-linking and the incorporation of CMC-Na, the hydrogel has excellent anti-swelling properties and mechanical properties (large stretchability of 955%, tensile strength of 252 kPa). Notably, after seven days of immersion in water (pH = 3, 5) and saline, stress and strain were elevated compared to the original hydrogel (strain up to 1460% and stress up to 805 kPa after immersion). The dynamic hydrophobic association of CTAC with SMA and the large number of hydrogen bonds within the hydrogel contributed to the excellent self-healing efficiency of the hydrogel (90%). The hydrogel was fabricated into a flexible strain sensor that showed keen sensitivity in the sensing range of 0–400% (GF values of 1.55, 2.87, and 5.03 for the ranges of 0–200%, 200–300% and 300–400%, respectively). It could accurately detect real-time signals of human movement in air, underwater, and seawater. Therefore, the P(AA-SMA)-CMC-Na hydrogel can meet the needs of underwater sensing and have great potential for applications in electronic skin, personal health detection, and flexible wearable electronics.

Despite the high prevalence of myopia among school-age children in China, many myopic students are reluctant to wear eyeglasses. This study estimates the effects of wearing eyeglasses on myopic students' academic performance, using data from a large-scale survey of middle-school students, the China Education Panel Survey. Our fuzzy regression discontinuity (RD) design, which exploits the jump in the probability of wearing eyeglasses at the threshold for myopia diagnosis, reveals that wearing eyeglasses improves myopic students' Chinese and maths test scores by 0.27 and 0.24 standard deviations, respectively.
