Objective: To establish a flow-through cell method for determining the release rate of bupivacaine multivesicular liposomes, and to explore the release mechanism of the multivesicular liposomes. Methods: Phosphate buffer solution (pH 7.0, containing 1% bovine serum albumin) was used as the release medium, with a volume of 100 mL. A dialysis tube with a molecular weight cut-off of 100 kDa was used in conjunction with a 22.6 mm tablet cell. The water bath temperature was maintained at 25 ℃. The flow rate was 16 mL · min^-1.The model-dependent methods were applied to fit the release curves of bupivacaine multivesicular liposomes produced by different manufacturing processes, to compare the similarity of the release curves, and to explore the release mechanism of the multivesicular liposomes. Results: The BiDoseResp mathematical model provided a good fit for the release curves of the three preparations produced by different manufacturing processes. Statistical analysis showed that the variances of the mean values for parameters A2 and h2 among the three preparations are homogeneous (P=0.391 > 0.05,P=0.151 > 0.05). The LSD test in multiple comparisons revealed that there was no significant difference in parameter A2 between batch 1 and the original product, while there were significant differences in parameter A2 between batch 2 and both the original product and batch 1 (P < 0.05). However, there were no significant differences in parameter h2 among the three preparations. The release of bupivacaine in liposomes involved both diffusion and erosion processes. As the drug was released from the liposomes, the liposomes themselves underwent structural rearrangement and dissolution. Conclusion: The flow-through cell method for determining the release rate of bupivacaine multivesicular liposomes is established, and its release curves can reflect the release characteristics of multivesicular liposomes. It can also preliminarily distinguish the release behavior of multivesicular liposomes produced by different manufacturing processes. This method provides a reference for the screening of generic drug quality control and consistency evaluation.

Objective: To study the establishment and optimization of the pathogen targeted next-generation sequencing (tNGS) process based on the probe capture method, as well as the automated implementation of it, and to verify the analytical performance. Methods: The factors influencing the tNGS methodology were analyzed, including the probe design and production quality control, data volume and sequencing read length.

As well as, the differences in limit of detection, precision and cross-contamination between manual operations and automated were compared. Results: The study showed that as the probe coverage increased, the limit of detection performance increases accordingly, and the probe still maintained high specificity. The optimized tNGS demonstrated good analyze performance in terms of accuracy, limit of detection, precision, specificity linearity and so on. Under the premise of the same limit of detection performance, the automated method was superior to manual operation in precision and cross-contamination resistance performance. Conclusion: The tNGS process established in this study has good analytical performance and provides a new strategy for clinical pathogen detection. Future studies should focus on clinical sample confirmation and automated process validation to promote better application of the technology in practical clinical work.

Objective：To improve the standardization and normalization of the in vitro evaluation of immune cell therapies and accelerate their clinical transformation process. Methods：An evaluation strategy for the anti-tumor effects of immune cell therapies, based on tumor organoid and organoid-on-chip models was formulated, through analyzing the characteristics of the evaluation of the effectiveness of immune cell therapies and the application potential of organoid and organ-on-chip technologies, and referring to internationally advanced guidelines for organoid and organ-on-chip evaluation, as well as the latest domestic and international research findings. Results and Conclusion：A consensus was formed on the application of tumor organoid and organoid-on-chip models in the evaluation of the anti-tumor effects of immune cell therapies. This consensus addressed their advantages, biological requirements, characterization criteria, experimental design and limitations: First, tumor organoid and organoid-on-chip models provide a more reliable and efficient tool for evaluating the efficacy of immune cell therapies. Second, the cell types and origins used in the model, culture conditions, and the tumor microenvironment should be taken into consideration before the evaluation. Third, the evaluation must include morphological, histopathological, genetic and biological functional characterization of tumor organoids, together with validation of anti-tumor effects. Fourth, the assay should set up appropriate control groups, determine the optimal ratio of effector cells to target cells, and select appropriate detection endpoints. Fifth, this approach still faces challenges such as insufficient pathological relevance and standardization of the models. In the future, it is necessary to further enhance the pathological relevance and standardization of tumor organoid and organoid-on-chip models to improve their predictive ability and to better facilitate the development and transformation of immune cell therapies.
