[Methods] The orthogonal design with three levels was carried out with microcrystalline cellulose, calcium hydrophosphate and cross-linked polyvinylpyrrolidone as three factors to optimize the preparation process. [Results] When microcrystalline cellulose 200 mg/tablet, calcium hydrophosphate 150 mg/tablet, and cross-linked polyvinylpyrrolidone 80 mg/tablet were added, the angle of repose could meet the requirements of tablet pressing, and the dissolution could reach more than 95% in 30 min. The results of the orthogonal test showed that the dissolution effect of self-made tablets was faster than that of commercial products. [Conclusions] The glucosamine hydrochloride chondroitin sulfate tablets prepared by this prescription have better quality.展开更多

It demonstrated the belief and determination of humanity to maintain peace, democracy and human dignity. The process of formulating the Declaration was difficult. But in the spirit of cooperation,countries finally succeeded in reaching a consensus on human rights.The making of the Universal Declaration of Human Rights had great value and significance for promoting world peace and development,and it has had a far-reaching impact on the rule of law in international human rights and the development of the human rights legal systems in various countries. A re-examination and analysis of the process of formulating the Universal Declaration of Human Rights will help us understand the purposes and objectives of the Declaration and review the great value of the spirit of the Declaration to the world today.展开更多
