In everyday life, traditional dressings such as band-aid and gauze are used for dealing with small ***, these dressings have shortcomings such as pain caused by tearing, inapplicability to joints, single functionality, and adverse reactions. Therefore, there is a great need for an inexpensive, comfortable, and multifunctional wound dressing. In this study, quaternized chitosan(QCS) with a high degree of substitution(107.84%) was successfully prepared and characterized using ultraviolet–visible(UV–vis) spectroscopy, Fourier transform infrared(FT-IR) spectroscopy, X-ray diffraction(XRD), and proton nuclear magnetic resonance(1H NMR). A series of QCS/F127 thermosensitive hydrogels were prepared by physical cross-linking and used as potential wound dressings. Then the temperature sensitivity, hemostatic ability, antibacterial activity, and sustained drug release effect of the hydrogels were investigated to evaluate their multifunctionality as wound dressings. Finally, the effect of QCS concentration on hydrogel properties was explored. The results show that the composite hydrogels have significant hemostatic, antibacterial, and sustained drug release abilities, and they can be rapidly transformed into a gel state and adhere to skin upon reaching body temperature. In addition, the properties of the hydrogels can be adjusted by varying the concentration of QCS, which allows for the preparation of wound dressings that are responsive to needs. Therefore, multifunctional QCS/F127 hydrogels with temperatureresponse characteristics are of great clinical research value as wound dressings.

Human milk fat （HMF） is the component that supplies the highest fraction of the infant＇s required dietary energy. Other sources of fat are necessary and crucial for infants while the breastfeeding is not possible, desirable or sufficient. There is enough scientific evidence that suggests the composition and distribution of the fatty acids affect the absorption of the fat in infants greatly, which influences the growth and health of infants. However, the composition and distribution of the fatty acids in certain fat such as cow milk fat or vegetable oil are different from those in human milk. So as to mimic human milk fat composition and structure, a series of human milk fat substitutes （HMFS） have been developed through enzymatic interesterification reaction during recent years This review described current trends in the production of HMFS, discussed the significance and methods of preparing HMFS and the problems and put forward potential solutions about this kind of product.

Cellulose macrofibers (MFs) are gaining increasing interest as natural and biodegradable alternatives to fossil-derived polymers for both structural and functional applications. However, simultaneously achieving their exceptional mechanical performance and desired functionality is challenging and requires complex processing. Here, we reported a one-step approach using a tension-assisted twisting (TAT) technique for MF fabrication from bacterial cellulose (BC). The TAT stretches and aligns BC nanofibers pre-arranged in hydrogel tubes to form MFs with compactly assembled structures and enhanced hydrogen bonding among neighboring nanofibers. The as-prepared BC MFs exhibited a very high tensile strength of 1 057 MPa and exceptional lifting capacity (over 340 000 when normalized by their own weight). Moreover, due to the volume expansion of BC nanofibers upon water exposure, BC MFs quickly harvested energy from environmental moisture to untwist the bundled networks, thus generating a torsional spinning with a peak rotation speed of 884 r/(min·m). The demonstrated rapid and intense actuation response makes the MFs ideal candidates for diverse humidity-response-based applications beyond advanced actuators, remote rain indicators, intelligent switches, and smart curtains.

Green-revertible albino is a novel type of chlorophyll deficiency in rice （Oryza sativa L.）, which is helpful for further research in chlorophyll synthesis and chloroplast development to illuminate their molecular mechanism. In the previous study, we had reported a single recessive gene, gra（t）, controlling this trait on the long arm of chromosome 2. In this paper, we mapped the gra（t） gene using 1,936 recessive individuals with albino phenotype in the F2 population derived from the cross between themo-photoperiod-sensitive genic male-sterile （T/PGMS） line Pei＇ai 64S and the spontaneous mutant Qiufeng M. Eventually, it was located to a confined region of 42.4 kb flanked by two microsatellite markers RM2-97 and RM13553. Based on the annotation results of RiceGAAS system, 11 open reading frames （ORFs） were predicted in this region. Among them, ORF6 was the most possible gene related to chloroplast development, which encoded the chloroplast protein synthesis elongation factor Tu in rice. Therefore, we designated it as the candidate gene of gra（t）. Sequence analysis indicated that only one base substitution C to T occurred in the coding region, which caused a missense mutation （Thr to Ile） in gra（t） mutant. These results are very valuable for further study on gra（t） gene.
