Since the enactment of China's first “Drug Administration Law of the People's Republic of China” in 1984, China has entered a phase of legal and standardized drug management. The drug regulatory authorities have continuously strengthened the construction of the legal and regulatory framework for drug supervision and have optimized the drug review and approval system. The accessibility of drugs for rare diseases is a significant challenge worldwide. To meet the medication needs of patients with rare diseases, China has introduced a series of incentive policies to fully support the development of drugs for rare diseases and accelerate their review and approval. This paper systematically reviews the historical evolution, development process, and reform achievements of China's rare disease drug review and approval system, and looks ahead to the future, aiming to further optimize the system to better meet the medication needs of patients.

OBJECTIVE To establish an experimental method using ICP-MS to study the compatibility between pantoprazole sodium for injection and neutral borosilicate glass injection bottle-coated stopper composite packaging materials. METHODS By conducting extraction experiments, simulated acceleration experiments, and migration experiments under long-term experimental conditions, the changes in elemental impurities of pantoprazole sodium for injection at different times were investigated. The simulated solution after erosion was analyzed to predict the tendency of detachment on the inner surface of boron tube bottles, and its migration amount was evaluated for safety. RESULTS The linear relationship of each element by ICP-MS method was good, and the correlation coefficient (r) was greater than 0.999 0. The quantitative limit was less than its corresponding limit of 10%. The average recovery rate was 97.5%-108.8%. In the extraction experiment, the elements with higher detected level in each sample were Si, B, and Al, but all were below the safety limits. The detected levels of other elements were relatively low, even below the detection limits. Under intermediate and long-term conditions of 6 and 12 months, the detection results of elemental impurities in various added components in the packaging materials were all lower than the AET values. CONCLUSION This method can effectively determine the content of various impurity elements in the sample and reveal their migration trends. The compatibility between the composite packaging components and pantoprazole sodium for injection is good, and the safety of the product meets the requirements. It provided a scientific basis for selecting boron tube bottle and film-covered stopper as the inner packaging material.

OBJECTIVE To provide reference and guidance for improving the development mechanism and content of guidelines (general technical requirements) for similar content published by Chinese pharmacopoeia commission and drug regulatory agency. METHODS By reviewing the similar guidelines (general technical requirements) published by pharmacopoeia commissions and drug regulatory agencies in China, the United States, Europe, and Japan, a comparison and analysis were conducted on their similarities, differences, and mutual references in terms of their development purposes, scope of application, and specific content. RESULTS In terms of preparations, biological products, stability, impurities, dissolution, microbiological testing methods, and validation of analytical methods, pharmacopoeia commissions and drug regulatory agencies in China, the United States, Europe, and Japan have similar guidelines (general technical requirements), and there are differences in the purposes and focuses. Except for China, other countries or regions have less repetitive content and no conflicting content in the guidelines (general technical requirements) for similar content published by pharmacopoeia commissions and drug regulatory agencies. The two complement each other and jointly support the drug standard system. CONCLUSION It is recommended that China's drug regulatory agency take the lead in determining the subjects, further optimizing and improving the harmonization mechanism, and harmonizing and unifying the guidelines (general technical requirements) developed by pharmacopoeia commission and drug regulatory agency based on the functions of each agency, to ensure that the two are clearly positioned in terms of development purposes, scope of application, and content. Strengthen the interoperability of similar content guidelines published by pharmacopoeia agency and drug regulatory agency and keep pace with international standards.

OBJECTIVE To investigate accurate identification methods for the Yi medicine Cyathulae Capitatae Radix, and provide scientific basis for its accurate application. METHODS A camera imaging system was used to identify original plant differences based on plant taxonomy. A trait identification method was established through the comprehensive application of cameras,stereomicroscopes, and fluorescence microscopy imaging systems. Optical microscopy, fluorescence microscopy, and polarizing microscopy imaging systems were used to identify the differences in microscopic identification ( cross section and powder ), and a thin layer identification method was established for the unique components of Cyathulae Capitatae Radix. RESULTS A key table for the origin and characteristics of the Cyathulae Capitatae Radix and its four adulterants is established, the main differences of the origin are the type and mode of inflorescence, the shape of stamens, the color of leaves, and the color and taste of the root epidermis. The differences in characters identification include color, lenticels, cross-section, texture, odor, and the location and intensity of fluorescence response under different colored light conditions. In microscopic identification, the transverse section of the root can be distinguished by the number of circles in the three vascular bundles, the number of strands in the central vascular bundle, and fluorescence reaction, but the difference in powder microscopic characteristics is not significant. The thin layer chromatography established with reference materials of saponin components such as cyaonoside A, cyaonoside B and chikusetsu saponin Ⅳa, in thin layer chromatography can effectively distinguish Cyathulae Capitatae Radix and its four adulterants, the thin layer chromatography established with the reference substance of sterol component amaranthone can effectively distinguish the other three adulterants except Cyathulae Radix. CONCLUSION Cyathulae Capitatae Radix and its four adulterants can be identified through their original plants, characteristics, microscopic cross-sections, and thin layer chromatography, and the five medicinal materials have significant differences in composition and should not be mixed.
