ABSTRACT

Tumor metastasis is an important cause of tumor treatment failure. Its molecular mechanism is closely related to tumor cells remodeling immune cells and immunosuppressive microenvironment, so as to create a suitable soil for tumor cell invasion and growth. "Huoxue Huayu" is one of the important therapeutic principles in cancer treatment, but the influence of Huoxue drugs on tumor metastasis has been controversial in clinical application. In this paper, we systematically summarized the comparative study of Huoxue drugs and Yiqi Huoxue drugs in tumor metastasis in recent years, and discussed the differences of molecular mechanisms of Huoxue drugs and Yiqi Huoxue drugs in anti-tumor metastasis from the perspective of immune remodeling, so as to provide scientific basis for clinical rational application of Huoxue drugs and Yiqi Huoxue drugs.

ABSTRACT

Traditional Chinese medicine(TCM) is an important feature of cancer treatment in China. The methods to tap the advantages of TCM, reasonably evaluate and accurately apply Chinese patent medicines have become current research hotspots and difficulties. TCM takes syndrome differentiation and treatment as the core, with the characteristics of overall regulation and multi-targets efficacy. Therefore, the post-marketing survival benefit evaluation of Chinese patent medicines for cancer is different from that in modern medicine. The primary treatment goals in cancer patients include to improve the disease control rate and prolong their survival time. At present, Chinese patent medicines for cancer patients are lacking indepth studies on survival benefit at the post-marketing stage. In addition, the characteristics of individualized treatment with TCM have also increased the complexity of clinical research on TCM. Therefore, it is of certain practical significance and necessity to evaluate the survival benefit of Chinese patent medicines for cancer after marketing. Based on this, in this paper, we first summarized the technical methodological means of survival benefit evaluation at this stage, and then explored the post-marketing survival benefit evaluation of Chinese patent medicines for cancer from three aspects: the evaluation of cancer treatment effect based on survival time and quality of life, treatment-related toxicity and the auxiliary effect of TCM, and the improvement effect for tumor-related symptoms. Based on the practices of early clinical researches, and according to the insufficient efficacy evaluation of current clinical research on Chinese patent medicines, this paper proposed to improve the evaluation system for clinical researches on Chinese patent medicines, establish the evaluation method with TCM characteristics, clarify the dominant population, lay a theoretical foundation for the evaluation of post-marketing survival benefits of Chinese patent medicines for cancer in the future, and promote the modernization process of TCM.

ABSTRACT

Objective To design and establish a new method for simultaneous determination of hepatitis B virus (HBV) pregenomic RNA (pgRNA) and DNA from nucleic acid extracts. Methods We established a duplex fluorescence quantitative PCR system to determine HBV pgRNA and DNA. DNA gel electrophoresis and quantitative PCR were used to test the specificity and sensitivity. We tested the feasibility and accuracy by determining the HBV pgRNA and DNA in HepG2.2.15 cells and the culture supernatants. Results The established duplex fluorescence quantitative PCR system has a good specificity and sensitivity. When it was used to determine cell culture supernatants with different dilution ratios, the dilution ratios and results were well correlated. However, this method was more suitable for the determination of HBV pgRNA and DNA in cell culture supernatants, rather than cell samples. Conclusion Our method can avoid inaccuracy of HBV RNA determination caused by HBV DNA contaminant in nucleic acid extracts, and realize simultaneous detection of HBV pgRNA and DNA in one PCR reaction, which greatly improves the determination efficiency and has potential clinical application value..

ABSTRACT

In genomic transcripts of mammalians, long non-coding RNA (lncRNA) is an important group due to its considerable absolute number as well as numerous types. By means of base complimentary paring or spatial conjunction with certain three-dimensional structures, different lncRNAs interact with other biological molecules such as proteins, RNAs and DNAs to exert different biological functions. Together, they constitute a regulatory network both intricate and delicate. More and more researches show that lncRNAs play important roles in the regulation of innate immunity, such as determining differentiation of innate immune cells, adjusting expression of inflammatory factors and participating in host-virus interaction. In this review, we described the biological effects of lncRNAs in innate immunity, and further illuminated the molecular mechanisms. Finally, we discussed the strategies and technologies for carrying out researches on innate immunity-related lncRNAs.
