Quality control is pivotal in the research and development of traditional Chinese medicine, whose connotation is not limi-ted to the qualitative or quantitative detection of an indicator component, but extends to the establishment of a whole process quality control system from the perspective of pharmaceutical product lifecycle management. This study discussed the quality control strategy of Chinese medicine based on the concept of pharmaceutical product lifecycle management, and proposed the following suggestions:(1) to focus on the "holistic view" and "phased" characteristics of quality control and strengthen the establishment of quality control strategy based on top-level design;(2) to strengthen the research on quality control of Chinese medicine based on quality risk management, focus on the correlations of quality control indicators with the safety and effectiveness of traditional Chinese medicine, and establish a quality evaluation system consistent with the characteristics of traditional Chinese medicine;(3) to consider the characteristics of different registration classifications in the establishment of quality control strategy;(4) to highlight the quality correlation research, strengthen the quality transfer research, ensure the quality traceability, and establish a sound quality management system;(5) to strengthen the quality research on marketed drugs to achieve dynamic quality improvement.

Osteoarthritis (OA) is a complex disease of cartilage characterised by joint pain, functional limitation, and reduced quality of life with affected joint movement leading to pain and limited mobility. Current methods to diagnose OA are predominantly limited to X-ray, MRI and invasive joint fluid analysis, all of which lack chemical or molecular specificity and are limited to detection of the disease at later stages. A rapid minimally invasive and non-destructive approach to disease diagnosis is a critical unmet need.

The cell painting assay is useful for understanding cellular phenotypic changes and drug effects. To identify other aspects of well-known chemicals, we screened 258 compounds with the cell painting assay and focused on a mitochondrial punctate phenotype seen with disulfiram. To elucidate the reason for this punctate phenotype, we looked for clues by examining staining steps and gene knockdown as well as examining protein solubility and comparing cell lines.

Focusing on the Yashkun population of Gilgit-Baltistan, an administrative territory in northern Pakistan, our study investigated mtDNA haplotypes as indicators of ancient gene flow and genetic diversity. Genomic DNA was extracted and evaluated for quality using agarose gel electrophoresis. The complete control region of mtDNA (nt 16024-576) was amplified via PCR, and sequencing was performed using the Big Dye Terminator Kit on an Applied Biosystems Genetic Analyzer.

Lycium barbarum is an important economic crop in the arid region of Northwest China, and the regulation of irrigation and fertilisation is an important way to improve the quality and yield of Lycium barbarum. To explore the effects of water-fertiliser coupling on photosynthesis, quality and yield of Lycium barbarum under irrigation methods based on predicted crop evapotranspiration (ET), ET was calculated via reference evapotranspiration (ET) predicted on the basis of public weather forecasts, and the irrigation water volume was determined as a proportion of this ET. A field experiment was conducted via a completely randomised experimental design with five irrigation water volumes (W0 (100% ET), W1 (90% ET), W2 (80% ET), W3 (70% ET) and W4 (65% ET)) and three fertiliser application rates (high fertiliser (FH), medium fertiliser (FM) and low fertiliser (FL)).

The presence of antibiotics in the environment is of significant concern due to their adverse effects on aquatic ecosystems. This study provides an assessment of potential ecological risks (RQ) associated with the concentrations of eight antibiotics and antiparasitics (amoxicillin-AMO, azithromycin-AZI, ciprofloxacine-CIP, ofloxacine-OFL, oxfendazole-OXF, lincomycin-LIN, sulfacetamide-SCE and sulfamethoxazole-SME) in the surface water of 13 urban lakes in Hanoi city, Vietnam during the period 2021-2023. The findings revealed considerable variations in the total concentrations of these 8 substances (T), ranging from below the method detection limit (< MDL) to 2240 ng L with an average of 330.
