OBJECTIVE To prepare vancomycin hydrochloride (VH)-loaded polydopamine (PDA) nanoparticles (VH@PDA nanoparticles), and study their antimicrobial effect in combination with photothermal therapy. METHODS Using PDA as the carrier, VH was loaded to prepare VH@PDA nanoparticles (PDA nanoparticles were prepared using the same method). The nanoparticles were characterized with laser particle size analyzer, transmission electron microscope, and UV visible absorption spectrometer; the drug loading capacity and encapsulation efficiency of the nanoparticles were determined. The near-infrared laser irradiation was adopted to determine their photothermal ability. Taking Staphylococcus aureus as the research object, the bactericidal properties of the nanoparticles in combination with photothermal therapy in vitro were clarified through plate colony coating method, live/dead staining analysis, crystal violet staining. Using L929 cells as the research object, the effects of VH@PDA nanoparticles at different mass concentrations (0, 3.125, 6.25, 12.5, 25, 50 and 100 μg/mL) on cell viability were investigated to assess their biocompatibility. RESULTS VH@PDA nanoparticles were successfully loaded with VH, exhibiting uniform particle size (approximately 300 nm), distinct pore size, and a spherical structure. The drug loading capacity was 11.34%, the encapsulation efficiency was 32.00%, the photothermal conversion efficiency reached 23.55%, and they demonstrated stable photothermal performance. The antibacterial effect results of the combined photothermal therapy demonstrated that without near- infrared laser irradiation, the antibacterial effects of VH, PDA nanoparticles, and VH@PDA nanoparticles were not significant. However, when subjected to near-infrared laser irradiation, VH@PDA nanoparticles exhibited a pronounced antibacterial effect. The results of the cell experiments revealed that after treatment with VH@PDA nanoparticles at various mass concentrations, the cell viability rates remained above 80%. CONCLUSIONS VH@PDA nanoparticles are successfully prepared, which exhibit stable photothermal properties, significant antibacterial effects when combined with photothermal therapy, and good biocompatibility.

This study was purposed to explore the significance of tissue factor (TF), tissue factor pathway inhibitor (IFPI) and interleukin-1beta (IL-1beta) in the evaluation of development, curative effect and prognosis of AL patients. ELISA was used to detect the levels of TF, TFPI and IL-1beta in plasma of 20 healthy individuals and 24 newly diagnosed AL patients. All the three indications of patients were measured in different stages including pre-chemotherapy phase, at 72 hours after chemotherapy, complete remission phase. The results showed that as compared with normal control, levels of TF, TFPI and IL-1beta in plasma of AL patients during pre-chemotherapy phase were higher (p < 0.01); as compared with pre-chemotherapy phase, levels of TF, IL-1beta were elevated at 72 hours after -chemotherapy (p < 0.05). However, the levels of TFPI was much lower than that of 72 hours after chemotherapy (p < 0.01). 16 out of 24 patients got complete remission, there was no difference of TF, TFPI and IL-1beta between complete remission group and normal control group. It is concluded that the levels of TF, TFPI and IL-1beta in plasma can be used as the indicators for understanding clinical features, evaluating disease status and predicting prognosis in acute leukemia patients.

Field surveys and literatures show that Polygonati Rhizome (Huangjing) was firstly recorded in Shen Nong&s Herbal Classic, and widely used as a medicinal and edible plant. It has a long history of cultivation, and the researches on chemistry have made some progress. The future development is prospected on health market. But the Polygonati Rhizome industry has faced a lot of problems, including the resource depletion, unstable quality, low-tech in cultivation and germplasm confusion, unclear of functional composition, decentralized, small scaled and primary processing products. The suggestion for sustainable development are listed below. First, the relevant researches should focused on material basis and biological mechanism of core effects. To speed up the selection and breeding of improved varieties, ensure the supply of high-quality seedlings and eliminate the unauthentic species are the most important measures. Secondly, to strengthen the conservation and rational use of wild resources, break through the key technologies of high-quality artificial cultivation on light regulation, site control, density control and precision harvesting are also very important. Thirdly, to reveal the toxicity-reducing-and-efficacy-enhancing mechanism of processing, optimize the parameters and setup the standard operating procedure are indispensable. Fourthly, that full advantage of the root, leaf, flower and fruit resources should be strengthened for enlarged health products based on the development of exact functional factors. Above all, Polygonati Rhizome could be a growing market in the future driven by the technological innovation, cultural creativity, integration of three industries, brand strategy and internet+technique.
