Low temperature plasma (LTP) technology has shown an outstanding application value in the pharmaceutical filed in recent ten years. This paper reviews the research advances in LTP, including its effects on enhancing or inhibiting drug activity, its combined use with drugs to treat cancers, its effects on the improvement of drug delivery system, its use in preparation of new inactivated virus vaccines, its use with mass spectrometry for rapid detection of drug quality, and the anti-tumor and sterilization effects of plasma-activated liquids. The paper also analyzes the challenges of LTP in the pharmaceutical filed, hoping to promote related research.

In this study, we investigated the therapeutic effect of artemisinin (Art) on lupus nephritis mice and its mechanisms by comparing the differences between lupus nephritis (LN) mice given Art and control mice in molecular biology, immunohistochemistry, and histopathology. The results showed that Art could remarkably relieve the symptoms, decrease the level of urine protein/24 h, and alleviate pathological renal lesions. The differences among the four groups in the expression of the NF-κBp65 protein, nuclear factor-κB (NF-κB) activity, and the expression of transforming growth factor-β1 (TGF-β1) mRNA in renal tissue suggested that Art can lower the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) and inhibit the expression of the NF-κBp65 protein and NF-κB and TGF-β1 mRNA in the renal tissues of LN mice. These results proved that it is reliable and effective to use Art to treat LN mice, and its therapeutic mechanisms should closely be related to the fact that Art can obviously decrease the serum levels of TNF-α and IL-6 and down-regulate the expression of the NF-κBp65 protein and NF-κB and TGF-β1 mRNA in renal tissues.
