The invention provides a head-mounted auxiliary device for meibomian gland treatment operation, and belongs to the technical field of meibomian gland treatment. Comprising a head-mounted frame and a cyst clamp body, side plates are fixedly connected to the two ends of the head-mounted frame, a clamping disc and a clamping ring are fixedly connected to the top end of the cyst clamp body, a first adjusting knob is screwed to the cyst clamp body, and an alignment adjusting mechanism is used for assisting medical staff in cyst excision. By arranging the alignment adjusting mechanism, a medical worker can fix the cyst clamp body by means of a clamping block and a first transverse rod, the medical worker does not need to hold the cyst clamp body manually all the time, and the convenience of surgical operation is improved; according to the cyst curette, a medical worker can extrude jelly-like substances, which are damaged by the curette, in the cyst from the notch by means of extrusion force of the clamping piece, so that the medical worker can be prevented from directly contacting the cyst with hands, the medical worker does not need to extrude the cyst by means of the curette, and the treatment convenience of the jelly-like substances in the cyst is improved.

The invention relates to the field of biomedical materials, and discloses a gradient biomimetic mineralized collagen-based artificial periosteum preparation method, which comprises: preparing a collagen acid solution; step-by-step mineralization and pH gradient construction: under a low-temperature stirring condition, synchronously dropwise adding a calcium salt solution and a phosphate solution into the collagen acid solution according to a constant molar ratio, and sequentially carrying out at least three mineralization stages; standing, concentrating and carrying out ion washing; performing pore gradient construction and forming, namely performing forming treatment on the obtained mineralized collagen jelly, and performing mold filling by adding pore-foaming agents with different contents in a layered manner or performing freezing by utilizing programmed cooling rate difference from bottom to top so as to form a porosity gradient structure corresponding to the mineralized gradient in the forming process; freezing and drying; crosslinking and drying again; and calendering to form a membrane to obtain the gradient collagen-based artificial periosteum which is uniform in thickness and flexible. According to the invention, a gradient mineralization and gradient porosity dual structure similar to a natural periosteum is successfully constructed.

This invention discloses a method for improving the thermal stability of ready-to-eat fish gelatin jelly, belonging to the field of aquatic food product technology. The method includes: rehydrating dried fish gelatin at low temperature, heating and boiling, and filtering to obtain fish gelatin juice; adding calcium chloride to the fish gelatin juice to pre-regulate the fish gelatin system using calcium ions; mixing the ion-pre-regulated fish gelatin juice with κ-carrageenan sol, and promoting cross-linking of fish collagen protein and polysaccharides through the bridging effect of calcium ions; and finally, filling, sealing, high-temperature sterilization, and cooling to obtain ready-to-eat fish gelatin jelly. By combining ion pre-regulation with polysaccharide cross-linking modification, a uniform and dense composite gel structure is constructed, significantly improving the thermal stability, gel strength, and resistance to water separation of the ready-to-eat fish gelatin jelly. This allows the product to maintain its complete solid gel morphology at 37 ℃, effectively solving the problem of traditional fish gelatin jelly easily softening and liquefying after being removed from the cold chain. It is suitable for room temperature storage and transportation and industrial production of ready-to-eat fish gelatin products.

The invention provides a preparation method and application of a potassium promoting type microbial fertilizer. The fertilizer is prepared by compounding paenibacillus mucilaginosus functional microspheres, activated bacterial powder and citric acid modified biochar. The inner core of the paenibacillus mucilaginosus functional microsphere is a diatomite-casein hydrolysate porous nutrition carrier loaded with thalli and provides physical support and endogenous nutrition, and the shell of the paenibacillus mucilaginosus functional microsphere is a calcium alginate gel layer and is embedded into a sinapic acid molecularly imprinted polymer microsphere; when root systems of target crops such as rape and leaf mustard secrete sinapic acid due to potassium deficiency, the molecules are specifically recognized and combined to trigger shell degradation, so that internal functional bacteria are released as required, the released bacteria activate soil mineral potassium, the modified charcoal adsorbs and stores potassium ions, and loss is reduced. Matching of microbial inoculum release and crop potassium demand signals is achieved, and the survival rate, the action pertinence and the potassium utilization efficiency of the microbial inoculum are improved.

The invention relates to the technical field of livestock manure treatment, and particularly discloses a compound microorganism composition and application thereof. The composition comprises immobilized tannic acid and paenibacillus mucilaginosus thalli, tannic acid and capsular polysaccharide secreted by strains are subjected to in-situ crosslinking to form a dynamic enhanced biological flocculation network, and the feces solid-liquid separation efficiency is remarkably improved; meanwhile, through the synergistic effect of chemical inhibition of tannic acid on urease activity and biological regulation and control of strains on methanogens and nitrification / denitrification flora, synchronous inhibition of methane and nitrous oxide in the excrement storage process is achieved for the first time. All the components of the composition are derived from natural materials or environmental functional microorganisms, the risk of secondary pollution is avoided, strains surviving after the treated manure is returned to the field can continuously play the probiotic functions of improving soil and promoting crop growth, and the composition has multiple benefits of efficient emission reduction, ecological safety and resource value increase and has wide application prospects. The method has a wide application prospect in the fields of livestock and poultry manure harmless treatment and agricultural green low-carbon development.

A soft jelly candy and a production method therefor. The soft jelly candy contains the following components: a) 30-45 parts by weight of carrageenan, b) 4-15 parts by weight of agar and / or pectin, and c) 2-16 parts by weight of gum arabic and / or gellan gum. Based on the total weight of the soft jelly candy after moisture is removed, the components a), b) and c) together account for 2.37-5.86% by weight. The production method comprises: uniformly mixing carrageenan, agar and / or pectin, and gum arabic and / or gellan gum with water, respectively. A "shrinkage" phenomenon does not occur to the soft jelly candy when the soft jelly candy contains a sugar alcohol and / or is high in functional component content.
