The rapid development of artificial intelligence （AI） technology provides new opportunities for the modernisation of traditional Chinese medicine （TCM） diagnosis. By analysing the foundation， research progress and difficulties of the combination of AI and TCM diagnosis， it is concluded that AI has made remarkable development in intelligence-driven modernization of TCM tongue diagnosis， pulse diagnosis， listening and smelling diagnosis and text processing， and there are useful explorations in the field of constructing data-driven TCM diagnostic model and multidisciplinary integration of TCM diagnostic models. However， the current integration of AI technology in TCM diagnosis still faces many challenges， such as the scarcity and uneven quality of clinical data， the limited ability of AI algorithms to express TCM thinking model of syndrome differentiation and empirical knowledge， and the possible existence of ethical and privacy issues. By systematically sorting out the current research status and development direction of AI-empowered TCM diagnostics， it is proposed to promote the application of AI technology in TCM diagnostics in four aspects， namely， strengthening the construction of TCM big data and talent cultivation， encouraging cross-disciplinary cooperation， improving the legal and ethical framework， and promoting the popularity of the technology in primary care， so as to enhance the modernisation of TCM diagnostics.

The abuse of antibiotics and other antimicrobial drugs has led to a significant increase in the prevalence of bacterial drug resistance. The advent of nanotechnology offers a promising way to address this challenge. Metal nanomaterials have emerged as a prominent class of antimicrobial agents, offering a number of advantages, including ease of preparation, high stability, potent efficacy against drug-resistant bacteria, and low toxicity. In this review, the antibacterial mechanisms of metal nanomaterials and the current research progress of gold, silver, copper, iron, platinum, palladium, and gallium nanomaterials and their application in the field of antibacterial were summarized with the aim of providing reference for the antibacterial use of metal nanomaterials.

Diseases caused by microbial infections, including bacteria, fungi, and viruses, are increasing every year. Currently, antibiotics are the primary treatment method for bacterial infections. However, over use of antibiotics can easily lead to bacterial resistance. Due to the broad-spectrum antibacterial properties of copper nanomaterials, they exhibit excellent antibacterial activity against both gram-negative bacteria and gram-positive bacteria. In this review, the preparation methods of copper nanomaterials were summarized, the antibacterial and antiviral effects of copper nanomaterials, and their applications in the fields of antibacterial and antiviral were discussed. Finally, the problems of copper nanomaterials in terms of toxicity and stability were summarized, and their future applications in the fields of antibacterial and antiviral were prospected.

OBJECTIVE To investigate the effect and mechanism of dihydroartemisinin(DHA)on lipo-polysaccharide(LPS)-induced acute lung injury(ALI)in mice using whole-genome sequencing.METHODS An ALI mouse model was established via intraperitoneal injection of 10 mg·kg-1 lipopolysaccharide.The mice were divided into normal control group(n=10),model group(n=10)and model+DHA group(n=10).The mice in the model+DHA group were injected intraperitoneally with 20 mg·kg-1 DHA,while those in the normal control group and LPS group were injected intraperitoneally with solvent of DHA,saline containing 1%Tween 80 and 10%Macrogol 400.The mice were executed 24 h after drug administration.The wet and dry weight ratio(W/D)of lung tissue was calculated.Hematoxylin-eosin(HE)staining was used to observe histopathological damage in the lung.Classified counts of inflamma-tory cells in alveolar lavage fluid were performed.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of interleukin-1β(IL-1β),IL-6,and tumor necrosis factor-α(TNF-α)in alveolar lavage fluid.Real-time quantitative PCR(RT-qPCR)was used to detect mRNA levels of placenta-specific 8(Plac8),Toll-like receptor 7(TLR7),IL-1β,IL-6 and TNF-αin lung tissue.The whole gene transcriptome was sequenced by RNA transcriptome sequencing(RNA-seq)using the Illumina HiSeq high-throughput sequencing platform before the function and signal pathway of differentially expressed gene mRNA between the groups were enriched and analyzed using GO and KEGG enrichment analysis methods.RESULTS Compared with the model group,the lung W/D values of mice,the pathological damage,inflammatory cells in alveolar lavage fluid,expression levels of IL-1β,IL-6 and TNF-α in alveolar lavage fluid(P<0.01,P<0.01,P<0.01),and the mRNA expression levels of IL-1β,IL-6 and TNF-α were significantly reduced in lung tissues in the model+DHA group(P<0.01,P<0.05,P<0.05).Whole gene transcriptome sequencing revealed that immune-related Plac8 and TLR7 genes were significantly upregu-lated(P<0.01)in mouse lung tissue of the model group but significantly downregulated(P<0.05)in mouse lung tissue of the model+DHA group.The results of RT-qPCR of Plac8 and TLR7 verified the results of whole gene transcriptome sequencing.GO and KEGG analysis showed that Plac8 and TLR7 were mainly related to the regulation of cytokine production,T/B cell activation and signal transduction,chemo-kine signal transduction and NF-κB signal transduction.CONCLUSION DHA might reduce LPS-induced lung damage and ameliorate the inflammatory condition in lungs of ALI mice.The mechanism of action may be that DHA negatively regulates the signaling pathways involved in TLR7 and Plac8 by decreasing the expressions of TLR7 and Plac8 mRNA before regulating a series of immune responses such as secretion of inflammation-related cytokines and activation of immune cells,thereby reducing inflam-matory damage in lungs.

Objective:To compare the perioperative outcomes and short-term graft patency between patients who underwent multivessel off-pump coronary artery bypass graft(OPCABG) via left intercoastal space or sternotomy.Methods:Between January 2017 and August 2019, 100 patients who underwent minimal invasive coronary artery bypass graft(MICS CABG) were compared with 235 patients who underwent OPCABG by single surgeon at our institute. Among them, 257 cases were male and 78 were female, aged 34 to 84 years, with mean age(61.35±8.79)years old. Due to important differences in patients’ characteristics, a propensity score-matched analysis based on 12 covariates was performed to match in a 1∶2 fashion. 82 patients(MICS group) were matched with 127 patients(OPCABG group). Surgical and postoperative outcomes were evaluated.Results:There was no statistical difference of perioperative mortality, myocardial infarction, and stroke rate( P>0.05). In MICS group, use of internal thoracic artery was higher and conversion to cardiopulmonary bypass was lower( P<0.05), but reoperation, new onset atrial fibrillation , and the use of mechanical device were similar( P>0.05). In addition, operation duration was longer but transfusion rate, postoperative chest tube drainage within 24 hours and postoperative hospital stays were less in the MICS group( P<0.05). LIMA, vein and overall graft patency were similar in the two groups shown by postoperative one-year CTA( P>0.05). Conclusion:MICS CABG is safe and feasible for patients with multiple coronary lesions. It has similar in-hospital outcomes and short-term graft patency but less transfusion and faster recovery compared to conventional OPCABG via sternotomy.
