The invention provides a limiting mechanism for a photovoltaic power generation equipment cleaning device. The limiting mechanism comprises photovoltaic power generation equipment which is arranged ina rotary swinging manner, guide rails which are symmetrically arranged on the two sides of the photovoltaic power generation equipment respectively and a cleaning roll which is rotationally arrangedon the guide rails; each guide rail comprises a linear guide rail and an arch-shaped guide rail; each linear guide rail is slantingly arranged; each arch-shaped guide rail is connected with the two ends of the corresponding linear guide rail; and limiting mechanisms, each of which comprises a fixing component and a lever component, are arranged on the tops of the linear guide rails respectively. The limiting mechanism provided by the invention has the beneficial effects that by utilizing locking of first limiting plates and the corresponding linear guide rails to limit the cleaning roll and through transmission matching between the lever components and the photovoltaic power generation equipment, locking between the first limiting plates and the corresponding linear guide rails is unlocked, the technical problem of limiting of the photovoltaic power generation equipment cleaning device is solved, regular release and limiting of the cleaning roll are realized, and the structure is novel.

The invention discloses a preparation method of a three-layer core-shell structure drug carrier with a near-infrared light remote response, belongs to the field of biomedical materials, particularly relates to a preparation method of a three-layer core-shell structure drug carrier with a near-infrared light remote response, and aims at solving the problem that cell imaging, photoactive therapy and light-controlled drug release cannot be simultaneously carried out by an existing method. The method comprises the following steps: with up-conversion nano-particles as a core, wrapping a solid silicon shell for embedding a photosensitizer methylene blue; wrapping the outmost layer mesoporous silica shell; loading a model drug rhodamine B with a mesoporous internal channel; carrying out surface modification on three-layer core-shell nano-particles to modify organic chain link molecules with a singlet oxygen response on the outer surface; connecting the link molecules with a guest molecule AD in a chemical bonding manner; and loading a drug into a mesopore, and then complexing the guest molecule AD and added beta-cyclodextrin to block the channel. The preparation method is applied to cancer diagnosis and treatment; and light-controlled drug release, photoactive therapy and cell imaging are realized in a trinity manner.

The invention belongs to the field of food processing, and particularly relates to a sausage and a processing method thereof. The sausage contains Allium macrostemon Bunge which accounts for 0.3-20 wt% of the sausage. The preparation method comprises the following steps: mincing fresh meat according to the formula amount, pickling with seasonings, and evenly mixing with Allium macrostemon Bunge and auxiliary materials, wherein the weight ratio of Allium macrostemon Bunge to auxiliary materials is (0.5-5):1, and the auxiliary materials contain black tea or Pu-Erh tea which accounts for 30-70 wt% of the auxiliary materials; and filling the fresh sausage, and volatilizing 15-40% of water. The sausage has the advantages of good mouthfeel and favorable color, and is applicable to patients with overhigh blood fat; by replacing the spice garlic with Allium macrostemon Bunge, the sausage has an intense garlic flavor; a proper amount of Allium macrostemon Bunge can obviously lower the generation amount of nitrites in the subsequent processing on the premise of ensuring the sausage mouthfeel; and in the sausage boiling process, the Allium macrostemon Bunge mixed in the sausage eliminates the slow release and timed release of effective constituents of nitrites, thereby thoroughly eliminating nitrites.

The invention relates to the field of medicines, and particularly relates to an oral mucosa drug delivery system. The oral mucosa drug delivery system comprises a matrix and inclusion particles dispersed in the matrix, wherein the inclusion particles comprise a drug A and an inclusion material wrapping the drug A; the inclusion particles contain lipid, and the lipid accounts for 60-100wt% of the weight of the inclusion material; and the matrix optionally further contains a drug B, and the drug B is the same as or different from the drug A. The drug release of the oral mucosa drug delivery system can be more stable, side effects caused by concentration fluctuation are avoided, and the drug can be continuously released for a longer time.

The invention relates to the field of medicine, in particular to a medicinal preparation, a medicinal transdermal patch containing the medicinal preparation and a preparation method of the medicinal transdermal patch. The medicinal preparation comprises coated medicine and uncoated medicine; the coated medicine comprises medicine A and an inclusion material coating the medicine A; the inclusion material contains hyaluronic acid and/or a derivative of the hyaluronic acid; the uncoated medicine is medicine B; and the medicine A and the medicine B are the same or different. The medicinal preparation and the medicinal transdermal patch provided by the invention have the advantages that an effective dose of medicine can be stably and durably (capable of reaching 7 days) released, and in addition, the controllability is high, so that the medication requirements of patients of different degrees can be met.

The invention provides an ROS-sensitive polyethylene glycol-polyester nano-drug delivery system which is characterized by comprising an ROS-sensitive polyethylene glycol hydrophilic segment A and a polyester hydrophobic segment B, and the hydrophilic and hydrophobic segments are linked by ROS-sensitive bonds to form A-B and B-A-B copolymers. The ROS sensitive material provided by the invention at least has one of the following advantages: the polymer material provided by the invention can be used for preparing a nano drug carrying material, drug wrapping is carried out through polymer self-assembly, drug molecules can be stabilized, ROS response sensitive release can be realized, and oral administration and the like can be realized.
