This invention relates to the field of traditional Chinese medicine (TCM) technology, and discloses a TCM composition for treating cachexia and its preparation method. The composition comprises five grains (a type of insect), Astragalus membranaceus, stir-fried Atractylodes macrocephala, Polygonatum sibiricum, Lycium barbarum, Ophiopogon japonicus, Citrus reticulata peel, Panax notoginseng, and Glycyrrhiza uralensis. Stir-fried Atractylodes macrocephala can be replaced with Poria cocos, Ophiopogon japonicus can be replaced with Polygonatum odoratum, and Citrus reticulata peel can be replaced with Amomum villosum. This formula is based on the principle of "strengthening the body's resistance, detoxifying and removing blood stasis," enhancing the effects of invigorating the spleen and stomach, promoting body fluid production and moistening dryness, while avoiding greasy and cloying substances that may hinder digestion. The preparation method involves cleaning, pulverizing, decocting, extracting, and drying the raw materials to obtain granules. This composition can be used to treat cachexia caused by various tumors such as lung cancer and liver cancer. Animal experiments have verified that it can significantly increase patients' food intake, improve cancer-related fatigue, inhibit tumor growth, alleviate muscle atrophy and splenomegaly, regulate blood routine, and improve anemia and immune function, providing a safe and effective option for the treatment of cachexia.

This invention relates to a SCC mix design method and system based on the shear strength theory of cement paste. Its core lies in establishing a cement paste shear strength prediction model. This model quantitatively evaluates the shear strength of the cement paste under a proposed mix proportion and compares it with a pre-determined reasonable range. Then, through iterative adjustments to the cementitious material composition and water-cement ratio, the shear strength of the cement paste falls within the target range, thereby simultaneously optimizing the paste rheology and determining the final mix proportion. This invention achieves complete quantitative design from aggregate to paste, economically and efficiently preventing SCC segregation and maximizing the use of auxiliary cementitious materials to reduce the cost of self-compacting concrete.

This invention discloses a high-efficiency dehydration device for dihydroxyanthraquinone, comprising a reaction vessel, a control box fixedly mounted on one side of the reaction vessel, a motor fixedly mounted on the top of the reaction vessel, a stirring rod fixedly mounted at the output end of the motor, and an addition mechanism for convenient quantitative addition of materials at the top of the reaction vessel. The addition mechanism includes a storage component, an electronic scale, a support plate, a collection box, an injection pipe, and a first solenoid valve. In use, the storage component pours dry-based sulfonic acid resin into the collection box, while the electronic scale weighs the resin until the desired weight is reached. At this point, the first solenoid valve opens, allowing the dry-based sulfonic acid resin in the collection box to be injected into the reaction vessel through the injection pipe. This utilizes the dry-based sulfonic acid resin to absorb moisture, thereby reducing the amount of sulfuric acid used and further reducing the amount of acidic wastewater, thus saving resources. Simultaneously, the electronic scale allows for convenient control of the amount of dry-based sulfonic acid resin added.

This invention discloses a Z-Scheme type composite photocatalytic material and its preparation method. Specifically, a series of Cu2O / rGO / BiOBr composite materials were successfully prepared using a two-step method, and the amount of Cu2O in the composite material was optimized by photoreduction of Cr(VI) under visible light irradiation.
