A hybrid porous structure may include a base template and an ionic polymer coating layer within the base template. The structural framework of the base template itself is non-porous. The base template fills the gaps among a plurality of imaginary spherical bodies stacked in three-dimensions as an imaginary stack. The ionic polymer coating layer is laminated on an inner surface of the base template inside the imaginary spherical bodies. The imaginary spherical bodies may have a pore in the center which is not occupied by the ionic polymer coating layer. The hybrid porous structure may include a plurality of necks, which are openings formed in a contact part where adjacent imaginary spherical bodies contact each other. The necks may be interconnected to the pores located in the center part of the imaginary spherical bodies.

Hypotonic formulations were evaluated for delivering water-soluble drugs and for drug delivery with muco-inert (that is, non-adhesive) mucus-penetrating nanoparticles (MPP). Hypotonic formulations markedly increased the rate at which drugs and MPP reached the epithelial surface, including deep into the vaginal folds. Minimally hypotonic formulations, preferably ranging from 20-220 mOsm/kg, provided rapid and uniform delivery of MPP to the entire vaginal surface, with minimal risk of epithelial toxicity. Data also show that there is a higher osmolality in the colon, such that vehicles with an osmolality above that of blood plasma (generally considered isotonic at ˜300 mOsm/kg), still lead to improvements in distribution in the colon due to rapid, osmotically-induced fluid absorption. The range for improved colon distribution with a hypotonic vehicle in the colon is ˜20 mOsm/kg-450 mOsm/kg.

The invention belongs to the field of botany, and particularly relates to an early evaluating method for tea tree winter resistance. The soluble sugar (mainly cane sugar) content is one important physiological basis for the strength of the tea tree winter resistance and one important presentation of the low temperature adaptability of the tea tree variety; and as the temperature is gradually lowered with the approaching of the winter, the cane sugar content of the tea tree leaves is gradually increased, however the tea tree variety with high winter resistance has higher-increased cane sugar content than the tea tree variety with low winter resistance. The early evaluating method for the tea tree winter resistance evaluates the winter resistance of the tea tree by measuring the cane sugar content in the tee tree leaves, so as to evaluate and select the tee tree variety with high winter resistance and provide basis for variety introduction for the tea tree.

The invention relates to a method for quickly preserving eggs preserved in rice wine under a reduced pressure. The method is characterized in that: when raw eggs (duck eggs or hen eggs) are preserved in a preserving agent, the internal vacuum degree of a preserving container is kept between 0.05 MPa below zero and 0.1 MPa below zero. A method for keeping vacuum comprises the following steps of: (1) decompressing and vacuumizing the raw eggs, namely decompressing and vacuumizing the preserving container for accommodating the raw eggs for 2 to 5 minutes until the internal vacuum degree of the preserving container is between 0.05 MPa below zero and 0.1 MPa below zero; (2) sucking prepared preserving liquid; and (3) decompressing and vacuumizing once again, namely decompressing and vacuumizing the preserving container for 10 to 25 minutes until the internal vacuum degree of the preserving container is between 0.05 MPa below zero and 0.1 MPa below zero. During preservation of eggs preserved in rice wine, the preserving container is decompressed and vacuumized, the raw eggs are soaked under a vacuum condition, the permeation pressure of preserving liquid is raised under the vacuum condition, and a negative pressure can be quickly and uniformly transferred to each part of the entire preserving container without being limited by the shapes and sizes of the raw eggs, so that liquid permeation speed of the raw egg is increased, the preserving time of the raw eggs is shortened to 8 weeks, and the production period of eggs preserved in rice wine is shortened greatly.

The invention relates to a method for preparing environmentally responsive monodisperse cyclodextrin polymer hollow microspheres. In the process of preparing multi-cavity poly (N-isopropylacrylamide-cyclodextrin) hollow microspheres, the hollow microspheres are endowed with environmental responsiveness, and in the process of preparing crosslinking cores, acid monomers are added to be copolymerized with NIPAM monomers so as to obtain acidic cores; and after cyclodextrin monomers and a crosslinking agent are added into the acidic cores so as to obtain core/shell-structured microspheres, the core/shell-structured microspheres are treated by using alkali liquor, and an ionization effect generated by acid-base neutralization accelerates the collapse of cores and the swelling of crosslinking shell layers, so that the permeability of the shell layers subjected to swelling is enhanced, therefore, a situation that PNIPAM (core) chains in the shell layers quickly escape so as to obtain microspheres is facilitated, and PNIPAM and acid ingredients in the microspheres also endow the hollow microspheres with pH and temperature responsiveness. The method disclosed by the invention solves the problems existing in hollow microsphere preparation implanted by using the existing 'self-removable' technique.
