Abstract: Since the introduction of domestic antivenom in the 1970s and 1980s, with the improvement of medical conditions in China after the reform and opening up, it has basically achieved popularization from the 1990s to the first few years of the 21st century. However, with the establishment of the socialist market economy and the completion of the medical and health reforms, the supply of antivenoms, which were originally sufficient, began to be in short supply. In order to solve the supply problem of shortage drugs such as antivenom, the national and local health authorities have carried out beneficial explorations to establish a shortage drug guarantee mechanism. The academic circle has also restarted the research on traditional Chinese medicine snakebite preparations and antivenoms that have been completed in the 20th century, and has been establishing provincial and municipal snakebite treatment centers and cross-regional snakebite treatment bases, conducting international snakebite treatment and making research collaborations to actively respond to the current shortage of antivenoms.Since entering the 21st century, the problem of poisonous snakebite has retreated in a secondary position in the medical community, and the research on progress in this area has basically no longer attracted the attention of the academic community. In fact, the tension of contemporary snake bite medical resources is not only domestic, but also showing a stronger status quo in the world, and is becoming a medical problem that cannot be ignored. This article uses the time-delayed research method, systematically combing the repeated fluctuations of anti -snake -toxic serum supply before 2000 to these years, as well as the relevant historical facts of the re-development and application of drugs such as traditional Chinese medicine snakebite preparations for alternatives. The attention of the academic and relevant departments attracted the attention of this issue, and the early prevention of snake bite in order to take into account the "green water and green mountains"policy and ensure the health of the people's lives are hoped to be taken.

Abstract: The mechanism of HPMC and VAE on the properties of dry-mixed mortar was studied by using self-developed crack resistance test method & etc. The results show that HPMC will significantly increase the water demand, VAE can significantly reduce the water, and the mixed result is higher than the sum of the two. Both HPMC and VAE can retain water, but the difference is very large, and the result of compound mixing is the superposition of two. HPMC will significantly reduce the wet unit weight, while VAE will slightly reduce the wet unit weight. The effect of compound blending is the superposition of the two. HPMC can significantly reduce the compressive strength and flexural strength; VAE can significantly improve the flexural strength, and the compressive strength can be increased when the dosage is high. The result of compound mixing is the sum of the two. HPMC can slightly improve the bond strength, while VAE can significantly improve the original bond strength with mortar. HPMC has a more significant effect on the compression ratio, and VAE has a more significant effect on the crack resistance; The compound addition is beneficial to the improvement of crack resistance.
