OBJECTIVE:To improve the automation and information level of Pharmacy intravenous admixture service (PIV-AS),and provide reference for the PIVAS development. METHODS:Related functions of DS8000 intelligent sorting system and its effect of PIVAS were introduced;work environment,workflow,work efficiency,labor intensity and sorting error before and af-ter the system application were compared. RESULTS:The application of intelligent sorting system achieved the automation of multi-ple links including reviewing,sorting,automatically counting,automatically generating hand-over lists of departments,statistical inquiring for related information in finished soft bag infusion sorting. Compared with manual sorting,it only covered less area, working environment was neat and orderly,workflow links was reduced (6 vs. 10),work time was shortened (average time for sorting per bag of infusion 13.53 s vs. 3.11 s),labor intensity was decreased,and work error rate was reduced (0.128‰ vs. 0.013‰);meanwhile,it improved the management for shading drugs,and achieved data analysis of PIVAS and management infor-mation. CONCLUSIONS:The application of DS8000 intelligent sorting system has improved the automation and information of PI-VAS,and promoted the construction and development of PIVAS.

Objective: To explore the mechanism of moxibustion for rheumatoid arthritis (RA) by observing the metabolite changes in urine using liquid chromatography-mass spectrometry (LC-MS)-based metabolomic analysis. Methods: Twenty-four rats were randomly divided into a control group, a model group, and a moxibustion group. Rats in the model and moxibustion groups were established as collagen-induced arthritis (CIA) models. The control and model groups did not receive any intervention; rats in the moxibustion group received moxibustion at Shenshu (BL23) and Zusanli (ST36). After three weeks of intervention, ankle joint, serum, and urine samples were collected for pathological examinations and metabolomic tests. Results: After moxibustion treatment, the CIA rats showed increased body mass, reduced swelling of the hind paws and arthritis score, decreased serum cytokine levels, and improved histopathological evaluation of the ankle joint. Twenty-four significantly altered metabolites were found, mainly involved in alanine metabolism, taurine and hypotaurine metabolism, tricarboxylic acid cycle, phenylalanine metabolism, tyrosine metabolism, and primary bile acid biosynthesis. These metabolites may serve as potential biomarkers for RA. Conclusion: Moxibustion can effectively resist inflammation in CIA rats. The potential biomarkers and the abnormal metabolic pathways of RA can be identified by LC-MS-based metabolomics. Metabolomics may be an effective way to explain the mechanism of moxibustion in treating RA.

Objective:To screen the differentially expressed immune-related genes(DEIRGs)in in-stent restenosis(ISR),and to analyze the immune cell infiltration in ISR,and to clarify the mechanism of occurrence and development of ISR.Methods:The mRNA gene expression data of GSE46560 dataset samples were downloaded from the Gene Expression Omnibus(GEO),and divided into ISR group and non-ISR group.The"Limma"package in R software was used to identify the differentially expressed genes(DEGs)which were then intersected with immune-related genes(IRGs)to identify the DEIRGs in ISR;R software was used for Gene Ontology(GO)functional enrichment andalysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis on DEIRGs;the STRING database was used to construct the protein-protein interaction(PPI)network,which was visualized and analyzed for Hub genes by Cytoscape software;the receiver operating characteristic(ROC)curve of the Hub genes were plotted,and the area under the curve(AUC)was calculated and the diagnostic value was evaluated;CIBERSORT software was used to analyze the immune cell infiltration in ISR;Pearson correlation analysis was used to analyze the relationships between the immune cells and the relationships between the immune cells and key genes.Results:A total of 331 DEGs were identified(P<0.05,|log2FC|>1),including 176 upregulated genes and 155 downregulated genes,and 38 DEIRGs were obstained.The GO functional enrichment analysis results showed that the DEIRGs were mainly enriched in biological processes(BP)such as defense response,immune response,and immune system;in cellular components(CC),the DEIRGs were located primarily in the extracellular region and cytoplasmic membrane;and in molecular functions(MF),the DEIRGs were mainly involved in regulating signaling receptor binding and cytokine receptor activity.The KEGG signaling pathway enrichment analysis results indicated that the DEIRGs in ISR were primarily enriched in the phosphatidylinositol 3-kinase/protein kinase B(PI3K-AKT)and transforming growth factor-β(TGF-β)signaling pathways.In the PPI network,CD19 had the highest node among the top 10 Hub genes.Compared with non-ISR group,the expression level of the CD19 gene in the samples in ISR group was increased(P<0.05).The AUC value in the ROC curve of CD19 gene expression was 0.92(P<0.05).The immune cell infiltration analysis results showed that compared with non-ISR group,the infiltration level of T lymphocyte follicular helper(Tfh)cells in the patients in ISR group were increased(P<0.05),the infiltration levels of immature B lymphocytes,CD8+T lymphocytes,naive CD4+T lymphocytes,and M0 macrophages were increased,but the differences were not statistically significant(P>0.05),while the infiltration levels of memory B lymphocytes,activated memory CD4+T lymphocytes,regulatory T cells,resting natural killer(NK)cells,activated NK cells,monocytes,resting mast cells,and neutrophils were decreased,but the differences were not statistically significant(P>0.05).There were positive correlations between Tfh cells and M0 macrophages and resting mast cells(r=0.88,P<0.05;r=0.68,P<0.05),and there were negative correlations between Tfh cells and monocytes and neutrophils(r=-0.49,P<0.05;r=-0.42,P<0.05).Conclusion:CD19 may influence the occurrence and development of ISR by regulating the activation of the PI3K-AKT signaling pathway to affect the Tfh and B lymphocytes.CD19 can serve as a biomarker for the diagnosis of ISR.

Objective:To explore the cause of inconsistency between the results of trisomy 7 by expanded non-invasive prenatal testing (NIPT-PLUS) and trisomy 18 by prenatal diagnosis.Methods:A pregnant woman who received genetic counseling at Jiaozuo Maternal and Child Health Care Hospital on July 5, 2020 was selected as the study subject. NIPT-PLUS, systematic ultrasound and interventional prenatal testing were carried out. The middle segment and root of umbilical cord, center and edge of the maternal and fatal surface of the placenta were sampled for the validation by copy number variation sequencing (CNV-seq).Results:The result of NIPT-PLUS indicated that the fetus has trisomy 7. Systematic ultrasound has shown multiple malformations including atrioventricular septal defect, horseshoe kidney, and rocker-bottom feet. However, QF-PCR, chromosomal karyotyping analysis, and CNV-seq of amniotic fluid samples all showed that the fetus was trisomy 18. Validation using multiple placental samples confirmed that the middle segment of the umbilical cord contains trisomy 18, the center of the placenta contained trisomy 7, and other placental sites were mosaicism for trisomy 7 and trisomy 18. Notably, the ratio of trisomy 18 became lower further away from the umbilical cord.Conclusion:The false positive results of trisomy 7 and false negative trisomy 18 by NIPT-PLUS was probably due to the existence of placental mosaicism. Strict prenatal diagnosis is required needed aneuploidy is detected by NIPT-PLUS to exclude the influence of placental mosaicisms.

In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.
