OBJECTIVE To explore suitable storage and transportation conditions for “internet plus drug delivery” under high- temperature conditions. METHODS A survey on high-temperature conditions in summer in Beijing was conducted; a retrospective analysis was conducted on “internet plus drug delivery” orders in our hospital from July 2021 to June 2022, summarizing the proportion and delivery range of drugs under different storage and transportation conditions. Additionally, simulation and validation experiments were performed to investigate optimal drug storage and transportation devices for “internet plus drug delivery” in Beijing under high-temperature conditions in summer. RESULTS The monthly average temperature in Beijing from June to August consistently exceeded 25.0 ℃ between 1991 and 2022. From July 2021 to June 2022, a total of 104 drugs were required to be stored below 25.0 ℃, accounting for 31.23% of the 333 drugs listed in our hospital’s “internet plus drug delivery” catalog in Beijing. These drugs were delivered 1 058 times, accounting for 19.63% of the total deliveries. Simulation and validation experiments demonstrated that the average maximum temperature during the next-day delivery process of “carton + foam box + composite aluminum film pearl cotton + 500 g ice bag×2 + gas column bag” was 9.6 ℃, the average minimum temperature was 2.7 ℃, and all the temperatures remained below 15.0 ℃, which could effectively ensure the quality of drugs. CONCLUSIONS Under the high-temperature conditions in summer in Beijing, the storage and transportation device of “carton + foam box + composite aluminum film pearl cotton + 500 g ice bag×2 + gas column bag” can meet the temperature requirements specified in the drug storage instructions for Beijing intra-city drug delivery.

BACKGROUND:Tissue engineering has brought new hope to the clinical challenge of liver failure,and the preparation of plant-derived decellularized fiber scaffolds holds significant importance in liver tissue engineering. OBJECTIVE:To prepare apple tissue decellularized scaffold material by using fresh apple slices and a solution of sodium dodecyl sulfate,and assess its biocompatibility. METHODS:Fresh apples were subjected to decellularization using phosphate buffer saline and sodium dodecyl sulfate solution,separately.Afterwards,the decellularized apple tissues and apple decellularized scaffold materials were decontaminated with phosphate buffer saline.Subsequently,scanning electron microscopy was used to assess the effectiveness of decellularization of the apple materials.Adipose-derived mesenchymal stem cells were extracted from the inguinal fat BALB/C of mice,and their expression of stem cell-related markers(CD45,CD34,CD73,CD90,and CD105)was identified through flow cytometry.The cells were then divided into a scaffold-free control group and a scaffold group.Equal amounts of adipose-derived mesenchymal stem cells were seeded onto both groups.The biocompatibility of the decellularized scaffold with adipose-derived mesenchymal stem cells was evaluated using CCK-8 assay,hematoxylin-eosin staining,and phalloidine staining.Cell adhesion and growth on the scaffold were observed under light microscopy and scanning electron microscopy.Furthermore,the scaffold was subdivided into the non-induced group and the hepatogenic-induced group.Adipose-derived mesenchymal stem cells were cultured on the decellularized apple scaffold,and they were cultured for 14 days in regular culture medium or hepatogenic induction medium for comparison.Immunofluorescent staining using liver cell markers,including albumin,cytokeratin 18,and CYP1A1,was performed.Enzyme-linked immunosorbent assay was used to detect the secretion of alpha fetoprotein and albumin.Additionally,scanning electron microscopy was employed to observe the morphology of the induced cells on the scaffold,verifying the expression of liver cell-related genes on the decellularized scaffold material.Finally,the cobalt-60 irradiated and sterilized decellularized apple scaffolds were transplanted onto the surface of mouse liver and the degradation of the scaffold was observed by gross observation and hematoxylin-eosin staining after 28 days. RESULTS AND CONCLUSION:(1)The scanning electron microscopy results revealed that the decellularized apple scaffold material retained a porous structure of approximately 100 μm in size,with no residual cells observed.(2)Through flow cytometry analysis,the cultured cells were identified as adipose-derived mesenchymal stem cells.(3)CCK-8 assay results demonstrated that the prepared decellularized apple tissue scaffold material exhibited no cytotoxicity.Hematoxylin-eosin staining and phalloidine staining showed that adipose-derived mesenchymal stem cells were capable of adhering and proliferating on the decellularized apple tissue scaffold.(4)The results obtained from immunofluorescence staining and enzyme-linked immunosorbent assay revealed that adipose-derived mesenchymal stem cells cultured on the decellularized apple scaffolds exhibited elevated expression of liver-specific proteins,including albumin,alpha-fetoprotein,cytokeratin 18,and CYP1A1.These results suggested that they were induced differentiation into hepatocyte-like cells possessing functional characteristics of liver cells.(5)The decellularized apple scaffold implanted at 7 days has integrated with the liver,with partial degradation of the scaffold observed.By 28 days,the decellularized apple scaffold has completely degraded and has been replaced by newly-formed tissue.(6)The results indicate that the decellularized scaffold material derived from apple tissue demonstrates favorable biocompatibility,promoting the proliferation,adhesion,and hepatic differentiation of adipose-derived mesenchymal stem cells.

OBJECTIVE To build a standardized simulation teaching system for resident pharmacists and evaluate its effects, and to provide reference for improving the competency of resident pharmacists. METHODS The established simulation teaching system for pharmacy residents’ standardized training in the study included revising the simulation teaching syllabus, setting up simulation teaching courses, implementing the teaching method through “six types of simulations”, applying objective structured clinical examination (OSCE) for assessment, building a simulation teaching team and strengthening the simulation teaching management. The effect evaluation was perfermed with mixed research method, and qualitative and quantitative research methods were used to collect and analyze data and information. RESULTS &&CONCLUSIONS Compared with the traditional teaching system, the passing rate of graduation examination (71.4% vs. 100%) and the score of after-department examination ([ 76.2±7.8) vs. (90.4±4.9)] under the simulation teaching mode were higher; through questionnaire surveys and qualitative interviews, we found that resident pharmacists who went through simulation teaching gave positive feedback on the role and impact of this system. The simulation teaching system can be used with good generalizability for the standardized training of resident pharmacists, and can provide strong basis and support for the high-quality development of hospital pharmacy.

Cholangiocarcinoma (CCA) is a category of highly heterogeneous and aggressive malignancy mainly originating from bile duct epithelial cells. The median survival time of untreated CCA patients is approximately 12?24 months, and the effectiveness and durability of surgical resection and neoadjuvant chemotherapy are limited. Results of the next-generation sequencing show that dysregulation of the immune system plays an important role in the pathogenesis of CCA. It has opened up new possibilities for the study of therapies targeting the natural course of aggressive CCA, such as immune checkpoint inhibitors, adoptive cell therapy, and tumor vaccines. Based on the current status of immunotherapy for CCA, the authors review the efficacy and dilemmas of current CCA immunotherapy strategies and look forward to the future treatment prospects of CCA.

Normal mammalian secondary palate development undergoes a series of processes, including palatal shelf (PS) growth, elevation, adhesion and fusion, and palatal bone formation. It has been estimated that more than 90% of isolated cleft palate is caused by defects associated with the elevation process. However, because of the rapidly completed elevation process, the entire process of elevation will never be easy to clarify. In this article, we present a novel method for three-dimensional (3D) reconstruction of thick tissue blocks from two-dimensional (2D) histological sections. We established multiplanar sections of the palate and tongue in coronal and sagittal directions, and further performed 3D reconstruction to observe the morphological interaction and connection between the two components prior to and during elevation. The method completes an imaging system for simultaneous morphological analysis of thick tissue samples using both synthetic and real data. The new method will provide a comprehensive picture of reorientation morphology and gene expression pattern during the palatal elevation process.
