Hulten, the three kinds of Digeda-species Mongolian medicinal materials belonging to the family Gentianaceae, bad been widely used for the treatment of liver diseases. To analyze comparatively the content of swertiamarin and swertisin among these three kinds of Digeda-species Mongolian medicinal materials. HPLC method was applied for qualitative and quantitative analysis of swertiamarin and swertisin. The Phenomenex C18 (4.6 mm x 250 mm, 5 μm) was used, chromatographic methanol and water as mobile phase, the flow rate was 1.5 mL x min(-1) with UV detected at 237 nm, column oven temperature was 25 degrees C. Results showed that the contents of swertiamarin and swertisin were closely related the different species and producing areas. The content range of swertiamarin in L. rotatum from different habitats was 1.73% - 2.72%, 0.43% - 0.96% for the swertisin content; the content of swertiamarin in G. barbata from Alxa Left Banner was 0.38%, and the content of swertiamarin and swertisin in G. barbata from the others habitats and G. Acuta from different habitats were all detected qualitatively. The contents of swertiamarin and swertisin among these medicinal plants showed a significant difference due to the different species and producing areas. As a consequence, these medicinal plants should not be put together for clinical applications.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

Severe muscle injury is still a challenging clinical problem. Exosomes derived from adipose stem cells (ASC-exos) may be a potential therapeutic tool, but their mechanism is not completely clear. This review aims to elaborate the possible mechanism of ASC-exos in muscle regeneration from the perspective of signal pathways and provide guidance for further study. Literature cited in this review was acquired through PubMed using keywords or medical subject headings, including adipose stem cells, exosomes, muscle regeneration, myogenic differentiation, myogenesis, wingless/integrated (Wnt), mitogen-activated protein kinases, phosphatidylinositol-4,5-bisphosphate 3-kinase/protein kinase B (PI3K/Akt), Janus kinase/signal transducers and activators of transcription, and their combinations. We obtained the related signal pathways from proteomics analysis of ASC-exos in the literature, and identified that ASC-exos make different contributions to multiple stages of skeletal muscle regeneration by those signal pathways.

OBJECTIVE:
To study the association of interleukin-10 (IL-10) -1082A/G, -819C/T, and -592C/A polymorphisms with IL-10 level and the severity of enterovirus 71 (EV71) infection in children.
METHODS:
A total of 137 children with hand-foot-mouth disease due to EV71 infection were enrolled as EV71 infection group, which was further divided into mild group with 91 children and severe group with 46 children, and 122 healthy children who underwent physical examination were enrolled as healthy control group. Related clinical data were collected. ELISA was used to measure the serum level of IL-10, and polymerase chain reaction-restriction fragment length polymorphism was used to analyze IL-10 -1082A/G, -819C/T and -592C/A polymorphisms.
RESULTS:
Compared with the healthy control group, the children with EV71 infection had significantly higher frequency of -1082 AA genotype and A allele (P<0.05). Among the children with EV71 infection, the severe group had significantly higher frequency of -1082 AA genotype and A allele than the mild group (P<0.05), while there was no significant difference in the distribution of IL-10 -819C/T and IL-10 -592C/A polymorphisms between the two groups (P>0.05). The severe group had a significantly higher serum level of IL-10 than the mild group and the healthy control group. IL-10 -1082 AA genotype, -819 TT genotype, and -592 AA genotype were associated with the low expression of IL-10 (P<0.05). As for haplotype, the EV71 infection group had a significantly lower frequency of GCC haplotype than the healthy control group (P<0.05). In the severe group, the children with ATA haplotype had a significantly lower IL-10 level than those with other haplotypes, and the children with GCC haplotype had a significantly higher IL-10 level than those with other haplotypes (P<0.05). There was no significant difference in IL-10 level between children with different haplotypes in the mild group and the healthy control group (P>0.05).
CONCLUSIONS
IL-10 gene polymorphisms are associated with IL-10 expression and the severity of EV71 infection in children.
