Objective:To establish a method for detecting serum non-ceruloplasmin-bound copper (NCC) by immunoprecipitation-inductively coupled plasma mass spectrometry (IP-ICP-MS) and evaluate its clinical application.Methods:Methodological evaluation research. Immunoprecipitation was first used to separate serum ceruloplasmin, followed by detection of serum NCC levels using ICP-MS. Two levels of quality control serum were reconstituted to determine the limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision of the self-developed method. The serum samples of 131 healthy individuals (healthy group) and 69 first-time diagnosed Wilson′s disease (WD) patients(WD group) from November 2023 to June 2024 in the Affiliated Hospital of Institute of Neurology, Anhui University of Traditional Chinese Medicine were collected. Using self-developed method detected the serum NCC levels, established the healthy reference intervals, and NCC levels between the two groups were compared using the Mann-Whitney U test. Results:The calibration curve exhibited excellent lineary across the concentration range of 1.562 to 300.000 μg/L, as demonstrated by coefficient of determination ( R2) of 0.999. The self-developed NCC method exhibited that the LOD was 0.99 μg/L, the LOQ was 3.29 μg/L, the accuracy (spike and recovery experience) was 87.67%?106.27%, and the intra-batch and inter-batch imprecision expressed as coefficient of variation ( CV) was 2.8%?7.3%, and the healthy reference range was 34.31-71.79 μg/L. The serum NCC levels in the WD group were 102.39 (74.38, 144.04) μg/L, which was significantly higher than those in healthy group (51.45±10.34) μg/L ( Z=?7.967, P<0.01). Conclusions:The established IP-ICP-MS method for detecting serum NCC meets the required analytical performance criteria. It is simply operative, highly sensitive, and provides accurate and reliable results, which could be used for clinical detection.

Objective:To analyze the international status and level of clinical trial quality in China, and explore the advantages and value of scientific regulation of clinical research quality in China.Methods:The data is sourced from the relevant reports publicly released by the National Medical Products Administration (NMPA), the inspection reports and announcements published by the Center for Food and Drug Inspection of the NMPA, the inspection data displayed on the official website of the U.S. Food and Drug Administration (FDA), as well as clinical diagnosis and treatment guidelines issued by the National Comprehensive Cancer Network (NCCN) of United States and the Chinese Society of Clinical Oncology (CSCO) (data as of July 21, 2023). This data provides an analysis of the regulatory status of the implementation of clinical drug trials in China, inspection data, and the approval and market entry of new oncology drugs and feedback from their practical application.Results:The clinical trial quality inspection systems of China and the United States are generally aligned, with similar inspection subjects, focus areas, and public disclosure pathways. However, each has its characteristics in terms of inspection targets and types. The quality of clinical trial data in China has been continuously improving. Between 2009-2015 and 2016-July 2023, China underwent 25 and 20 FDA Bioresearch Monitoring (BIMO) inspections, respectively. The inspection results showing "No Action Indicated" (NAI) improved from 48.0% to 85.0%, while "Voluntary Action Indicated" (VAI) decreased from 44.0% to 15.0%. Official Action Indicated (OAI) measures were required in 2009 and 2012. Compared to the 2009-2015 period, there has been a clear upward trend in the quality of clinical trial data since 2016. From 2016 to July 2023, the number of new oncology drugs developed by Chinese pharmaceutical companies and included in professional guidelines has steadily increased. Specifically, 37 drugs (58.7%) were included in the 2022 edition of the CSCO guidelines, and 15 drugs (23.8%) were included in the 2023 edition of the NCCN guidelines, with 10 of these drugs featured in both guidelines.Conclusions:The implementation quality of clinical trials in China has gained a certain level of international recognition and competitiveness. This progress is attributed to national macro-level guidance, a unique institutional model, and clinical practices aligned with international standards. In the future, it will be necessary to further strengthen the scientific regulatory system and enhance clinical research capabilities to continue advancing the high-quality development of clinical trials.
