Background: Short videos on social media are playing an increasingly important role in cancer health education today. It is important to explore how the actual communication effect of health videos and the knowledge absorption of users are influenced by different factors of the video creation process., Objective: The objective of our study is to access the factors influencing breast cancer health education through short videos on efficiency and quality., Methods: Three pairs of videos about breast health were created and participants completed questionnaires before and after watching the videos. A paired t -test was used to analyze within-group change scores. RM-ANOVA was used to assess the relationship between the pretest, posttest, and three variables., Results: Watching short videos can significantly increase viewers' knowledge of related health topics ( p  < 0.05). The viewers' concentration level while watching was significantly higher for the video with background music (BGM) than for the video without BGM ( p  = 0.006). The viewers' willingness to share was significantly higher for the video with a progress bar than for the video without a progress bar ( p  = 0.02). Using an interpreter wearing a doctor's uniform instead of casual wear and setting a progress bar can significantly improve the efficiency of knowledge absorption ( p  < 0.05)., Conclusion: A uniformed interpreter, BGM and a progress bar are factors influencing the efficiency of short health videos. They can be applied in video making to explore better ways of promoting cancer health education in the new mobile Internet environment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Xu, Wu, Du, Zhuang, He, Ma, Zeng, Liang, Xu, Xie and Lin.)

The difficulties such as how to accurately locate acupoints and safely insert needles are presented in acupuncture robot. The puncture robot with high technological similarity to acupuncture robot is getting mature, and a large number of human trials and animal experiments have been conducted for the development of puncture robot. Through comparing the similarities and differences between puncture robot and acupuncture robot in the aspects of through-skin puncture, needle insertion and needle removal, the valuable technology of puncture robot is analyzed for the development of acupuncture robot, and the crucial direction of technology migration is determined. ①Integrating the mechanical feedback and medical imaging technology and utilizing the multi-modal perception to achieve the safety of acupuncture operation. ②Emphasizing the integration of the existing designs of chest puncture robot to realize the acupuncture operation with inhalation and exhalation involved. ③Focusing on the development of relevant technology of automatic needle removal through conducting the actual scenario of treatment with acupuncture robot in patients under non-anaesthetic condition.

Precise revealing the mechanisms of excited-state intermolecular proton transfer (ESPT) and the corresponding geometrical relaxation upon photoexcitation and photoionization remains a formidable challenge. In this work, the compound (E)-4-(((4H-1,2,4-triazol-4-yl)imino)methyl)-2,6-dimethoxyphenol (TIMDP) adopting a D-π-A molecular architecture featuring a significant intramolecular charge transfer (ICT) effect has been designed. With the presence of perchloric acid (35 %), TIMDP can be dissolved through the formation of a HClO 4 -H 2 O-OH(TIMDP)-N(TIMDP) hydrogen-bonding bridge. At the ground state, the ICT effect is dominant, giving birth to crystals of TIMDP. Upon external stimuli (e.g., UV light irradiation, electro field), the excited state is achieved, which weakens the ICT effect, and significantly promotes the ESPT effect along the hydrogen-bonding bridge, resulting in crystals of [HTIMDP] + ⋅[H 2 O]⋅[ClO 4 ] - . As a consequence, the mechanisms of the ESPT can be investigated, which distorted the D-π-A molecular architecture, tuned the emission color with the largest Stokes shift of 242 nm, and finally, high photoluminescence quantum yields (12 %) and long fluorescence lifetimes (8.6 μs) have achieved. These results not only provide new insight into ESPT mechanisms, but also open a new avenue for the design of efficient ESPT emitters., (© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)

A four-step route for the synthesis of 2-methoxyestradiol (5) starting from 17β-estradiol (1) has been achieved with a 51% overall yield. The key step was the ruthenium-catalyzed ortho-C(sp 2 )-H bond hydroxylation of aryl carbamates. Using dimethyl carbamate as the directing group, [RuCl 2 (p-cymene)] 2 as the catalyst, PhI(OAc) 2 as the oxidant and trifluoroacetate/trifluoroacetic anhydride (1:1) as the co-solvent, the hydroxyl group could be singly installed at the 2-position of 3-dimethylcarbamoyloxyestradiol (2) with 65% yield. Subsequent methylation of hydroxy and removal of dimethyl carbamate afforded 2-methoxyestradiol (5)., (Copyright © 2019 Elsevier Inc. All rights reserved.)

The organometallic cation 1 (Fe(bipy-NH 2 ) 3 2+ , bipy-NH 2 = 4,4'-diamino-2,2'-bipyridine), which was constructed in situ in solution, can bind CO 2 from air effectively with a stoichiometric ratio of 1:4 (1/CO 2 ), through the formation of "H-bonded CO 2 " species: [CO 2 -OH-CO 2 ] - and [CO 2 -CO 2 -OH] - . These two species, along with the captured individual CO 2 molecules, connected 1 into a novel 3D (three-dimensional) architecture, that was crystal 1·2(OH - )·4(CO 2 ). The adsorption isotherms, recycling investigations, and the heat capacity of 1 have been investigated; the results revealed that the organometallic cation 1 can be recycled at least 10 times for the real-world CO 2 capture applications. The strategies presented here may provide new hints for the development of new alkanolamine-related absorbents or technologies for CO 2 capture and sequestration.
