The invention proposes to use a plant material derived from Marrubium vulgare for a non-therapeutic cosmetic treatment for tightening skin pores, said plant material comprising an effective amount of Forsythoside B as the active molecule. The plant material is preferably constituted of a cellular extract of dedifferentiated plant cells freed from cellular debris. This treatment is particularly intended for refining skin grain and/or for treating skin with an oily tendency.

The invention discloses a sodium alginate modified ropivacaine hydrochloride multivesicular liposome microsphere as well as a preparation method and an application thereof. The preparation method comprises the following steps: firstly, uniformly mixing and dispersing a nano calcium carbonate gel initiator into liquid paraffin, adding multivesicular liposome under the condition of uniform stirring, then adding a sodium alginate solution, and uniformly mixing; and then adjusting the pH value to 3.0-5.8, and rapidly initiating gelation reaction by free calcium ions to form the uniform gel-coated multi-vesicular liposome microspheres with a net-shaped cross-linked structure. The multi-vesicular liposome microsphere has the characteristics of clear structure, uniform particle size, stable state, long slow release time and the like. Compared with an existing preparation method, the preparation method has the advantages that the encapsulation effect of the final multi-vesicular liposome is guaranteed, the surface of the multi-vesicular liposome is uniformly covered with the sodium alginate, the problem that the sodium alginate is connected into a sheet is solved, the stability of the multi-vesicular liposome is enhanced, and therefore the slow release effect is improved. Meanwhile, the use amount of chloroform in the organic solvent can be reduced.

The invention discloses a method for adjusting the misalignment of shells of a mold for fan blades during assembling. The mold comprises an upper shell and a lower shell, wherein the upper shell is fixed on an upper mold steel frame, and the lower shell is fixed on a lower mold steel frame; the upper shell and the upper mold steel frame are put on the lower shell and the lower mold steel frame respectively; the upper shell and the lower shell are abutted together to form a hollow fan-blade mold cavity. The method comprises the following steps of: arranging a detachable adjusting device on the lower mold steel frame, wherein the adjusting device is provided with an adjusting nut; rotating the adjusting nut so that the adjusting nut pulls the upper mold steel frame and the upper shell to move transversely together through a screw rod to align the upper shell to the lower shell; locking and fixing the upper mold steel frame and the lower mold steel frame by a group of mold locking and positioning devices; detaching the adjusting device. The invention aims to provide the method and the device for accurately and conveniently adjusting the misalignment of the shells of the mold for the fan blades during assembling.
