This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Objective To screen differentially expressed long non-coding RNAs (lncRNAs) in the liver of mice infected with Schistosoma japonicum during the chronic pathogenic stage and identify their functions, so as to provide insights into unravelling the role of lncRNAs in S. japonicum infection-induced liver disorders. Methods Twenty 6-week-old C57BL/6 mice were randomly divided into two groups, of 10 animals each group. Each mouse in the experimental group was infected with (15 ± 2) S. japonicum cercariae via the abdomen for modeling chronic S. japonicum infection in mice, and distilled water served as controls. All mice were sacrificed 70 days post-infection, and mouse liver specimens were sampled for RNA extraction and library construction. All libraries were sequenced on the Illumina NovaSeq 6000 sequencing platform. Data cleaning was performed using the fastp software, and reference genome alignment and gene expression (FPKM) calculation were performed using the HISAT2 software. Potential lncRNA sequences were predicted using the software CNIC, CPC, Pfam, and PLEK, and potential lncRNAs were screened. Differentially expressed lncRNAs were screened with the DESeq2 software and subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses to identify biological processes and metabolic pathways involved in target genes of differentially expressed lncRNAs. Results A total of 333 potential lncRNAs were screened, and 67 were identified as differentially expressed lncRNAs, including 49 up-regulated and 18 down-regulated lncRNAs. A total of 53 target genes were predicted for differentially expressed lncRNAs. GO enrichment analysis showed that these target genes were mainly enriched in biological process and molecular function, among which Sema7a, Arrb1, and Ccl21b genes may be hub target genes for positive regulation of extracellular regulated protein kinase 1 (ERK1) and ERK2 cascades and may participate in the regulation of collagen expression. KEGG enrichment analysis showed that the target genes of differentially expressed lncRNAs were mainly enriched in cytokine-cytokine receptor interaction, viral protein interactions with cytokines and cytokine receptors, chemokine signaling pathway, and nuclear factor kappa-B (NF-κB) signaling pathway. Conclusions This study identifies differentially expressed lncRNAs and functional enrichment of their target genes in the liver of mice during the chronic pathogenic stage of S. japonicum infection. Up-regulated lncRNAs may affect biological processes of ERK1/2 cascades and chemokine signaling pathways via target genes Sema7a, Arrb1, and Ccl21b, thereby affecting collagen expression and inflammatory signal pathways, ultimately affecting the development of liver disorders.

Objective To study the effect of Salidroside(Sal)on platelet activation and aggregation and the interaction between human platelets and MDA-MB-468 cells of breast cancer.Methods Human platelets were collected,platelet sus-pension was prepared,and platelets were treated with different concentrations of Sal.The effects of Sal on platelet activation and aggregation were detected by thromboelastogram(TEG)and flow cytometry.Breast cancer MDA-MB-468 cells were cul-tured in vitro,and human platelets were treated with different concentrations of Sal,and then activated by thrombin.The effects of Sal on the interaction between platelets and MDA-MB-468 cells were analyzed by adhesion test and scratch test.Re-sults TEG detection:The ADP inhibition rate in the blank control group was(10.97±12.69)%,and the ADP inhibition rate in all Sal intervention groups was higher than that in the blank control group(P＜0.05).The AA inhibition rate was(8.11±7.84)%in the control group and(25.96±15.18)%in the 5 μmol/L Sal intervention group,and the difference was statistically significant(P＜0.05).Flow cytometry:The expression of CD62P on platelet surface in 40 and 60 μmol/L Sal groups was(56.5±0.17)%and(65.50±0.36)%,respectively,and the difference was statistically significant compared with the positive control group(76.53±0.49)%(P＜0.05).The percentages of PAC-1 expression on platelet surface in 40 and 60 μmol/L Sal groups were(62.20±0.10)%and(58.47±0.15)%,and the difference was statistically significant com-pared with the positive control group(72.10±0.20)%(P＜0.05).Adhesion experiment:Platelets can have adhesion with MDA-MB-468 cells,and activated platelets have stronger adhesion ability.The adhesion rate in the Sal group was signifi-cantly lower than that in the positive control group,and was negatively correlated with the concentration of Sal.Scratch test:The cell mobility at 24 h in the positive control group was(12.71±0.70)%,and the cell mobility in each Sal treatment group was(4.51±0.44)%,(3.85±0.11)%,(5.37±0.36)%,(4.15±0.13)%and(3.55±0.38)%,respectively,showing significant decrease compared with the positive control group(P＜0.05).After 48 h of Sal treatment,the cell mobility of 10,20,40 and 60μmol/L Sal groups decreased,and there was a statistical difference compared with the positive control group(P＜0.05).Conclusion Sal can inhibit the adhesion between activated platelets mediated by thrombin and MDA-MB-468 cells and the migration of MDA-MB-468 cells.

Objective:To investigate the clinical efficacy of distal tibiofibular screw fixation combined with ligament repair for the treatment of ankle fracture accompanied with distal tibiofibular syndesmosis injuries.Methods:A retrospective cohort analysis was made on clinical data of 72 patients with ankle fracture accompanied with distal tibiofibular syndesmosis injuries admitted to 909th Hospital of Joint Service Support Force of PLA from September 2017 to September 2020, including 38 males and 34 females, aged 19-65 years [(42.5±12.2)years]. The fracture was type B in 30 patients, type C 1 in 29 and type C2 in 13 according to Danis-Weber classification. A total of 36 patients were treated by distal tibiofibular screw fixation combined with ligament repair (fixation+repair group) and 24 patients by distal tibiofibular screw fixation (fixation group). Operation time, intraoperative blood loss and hospital stay were recorded. Visual analogue scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot score and ankle range of motion (ROM) were determined at 1, 3 months postoperatively and at the final follow-up. Complications were documented. Results:All patients were followed up for 12-22 months [(15.9±2.2)months]. There were no significant differences in operation time, intraoperative blood loss and hospital stay between the two groups (all P>0.05). VAS in fixation+repair group was (3.1±1.0)points and (2.1±0.6)points at 1, 3 months postoperatively, significantly lower than (3.9±0.8)points and (2.6±0.8)points in fixation group (all P<0.05), but the score showed no significant difference between the two groups at the final follow-up ( P>0.05). AOFAS score in fixation+repair group was (64.7±4.0)points, (73.2±3.4)points and (87.2±3.4)points at 1, 3 months postoperatively and at the final follow-up, significantly higher than (60.1±4.9)points, (70.2±1.9)points and (84.1±2.6)points in fixation group (all P<0.05). There was no significant difference in the ROM between the two groups at 1 month postoperatively ( P>0.05), but the ROM at 3 months postoperatively and at the final follow-up in fixation+repair group [(44.4±2.9)° and (52.3±2.5)°, respectively] was significantly higher than that in fixation group [(41.4±2.7)° and (50.1±2.7)°, respectively] (all P<0.05). There was 1 patient with internal fixation loosening in fixation+repair group, with the incidence of complications of 3% (1/36). While the incidence of complications was significantly lhigher in fixation group [17%(6/36)], including 2 patients with re-separation of distal tibiofibular syndesmosis, 2 with internal fixation loosening and 2 with internal fixation breakage ( P<0.05). Conclusion:Compared with distal tibiofibular screw fixation, distal tibiofibular screw fixation combined with ligament repair for the treatment of ankle fracture accompanied with distal tibiofibular syndesmosis injuries is effective to early relieve ankle pain, improve ankle function and ROM, and reduce occurrence of complications.
