Dual-layer spectral detector CT is a new spectrum CT imaging technology based on detector being able to obtain both images similar to true plain and spectral images in one time scanning.The reconstructed multi-parameter spectral images can not only improve image quality,enhance tissue contrast,increase the visualization and detection ability of occult lesions,but also provide qualitative and quantitative analysis of the lesions,so as to provide more imaging information and multi-dimensional diagnostic basis.The research progresses of dual-layer spectral detector CT for preoperative evaluation on colorectal cancer were reviewed in this article.

OBJECTIVE: To study the molecular epidemiology of thalassemia in Jiaxing area of Zhejiang province and provide a basis for prenatal diagnosis, genetic counseling and prevention and control of birth defects. METHODS: A total of 24 003 pregnant women who presented at the Jiaxing Maternal and Child Health Care Hospital from April 2017 to September 2021 were enrolled. Capillary hemoglobin electrophoresis in combination with routine blood test were used for primary screening for carriers of thalassemia-associated mutations, and those with positive results were subjected to fluorescence quantitative PCR assay. Prenatal diagnosis was provided for couples with a risk of giving birth to children with intermediate or severe thalassemia. RESULTS: Among the 24 003 pregnant women, 1 211 cases were suspected as carriers of thalassemia-associated mutations, among whom 443 (36.58%) were confirmed by genetic testing. Among these, carriers of α-, β- and α-complex β-globin gene mutations have accounted for 27.31% (121/443), 70.65% (313/443) and 2.04% (9/443), respectively. The result of prenatal diagnosis for an at-risk couple was --SEA/αCSα, and the fetus was predicted to have intermediate or severe thalassemia. Termination of the pregnancy was recommended. CONCLUSION Hemoglobin electrophoresis combined with routine blood test during pregnancy may be used as a preliminary screening measure for carriers of thalassemia-associated variants. Combined with genetic testing, this will be of great significance for the control of thalassemia in this region.

Qingyan Dropping Pills have the effects of relieving wind and heat, detoxifying, and promoting the pharynx. It is commonly used in traditional Chinese medicines to treat acute and chronic pharyngitis, as well as sore throats and dry throats caused by surgery. Recently, many studies have shown that Qingyan Dropping Pills have certain effects on bacteriostasis, anti-inflammatory, antioxidant, and antiviral activities. As the coronavirus disease 2019 (COVID-19) pandemic enters the post-epidemic era, the regular use of drugs for COVID-19 pandemic symptoms has become a new trend. Therefore, there is a good market prospect to explore and develop Chinese patent medicines with antiviral effects. A preliminary study on the herbal formula and material basis of Qingyan Dropping Pills revealed that they have potential for antiviral applications. In this paper, the research on the quality study and antiviral effect of Qingyan Dropping Pills was reviewed, and the research direction of its secondary development was discussed to provide ideas and references for the new use of old traditional Chinese medicines.

Objective: Taxifolin is a natural flavonoid compound that can be isolated from onions, grapes, oranges and grapefruit. It also acts as a medicine food homology with extraordinary antioxidant and anti-inflammatory activity. This study aims to explain the protective effects and potential mechanisms of taxifolin against inflammatory reaction. Methods: Levels of interleukin (IL)-6, IL-1β and intracellular reactive oxygen species (ROS) were assessed in different time after the treatment of taxifolin in RAW264.7 cells induced by lipopolysaccharide (LPS). Subsequently, the mRNA and protein levels of inducible nitric oxide synthase (iNOS), vascular endothelial growth factor (VEGF), cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α and the phosphorylation expression levels of the MAPK signal pathway were also evaluated. A silico analysis was used to explain the binding situation for the investigation of taxifolin and MAPK signal pathway. And then MAPK inhibitors were used to reveal the expression level of iNOS, VEGF, COX-2 and TNF-α in RAW264.7 cells. Results: It was demonstrated that cell inflammatory damage induced by LPS was significantly alleviated after the treatment of taxifolin. Then, the mRNA and protein levels of iNOS, VEGF, COX-2 and TNF-α were reduced and the phosphorylation expression levels of the MAPK signal pathway were down-regulated remarkably as well. In silico analysis, taxifolin could form a relatively stable combination with MAPK signal pathway. MAPK inhibitors showed increasing or decreasing effect in the mRNA levels of iNOS, VEGF, COX-2 and TNF-α, which suggesting that taxifolin down-regulated iNOS, VEGF, COX-2 and TNF-α expressions were not entirely through the MAPK pathway. Conclusion: This finding demonstrated that taxifolin improved the inflammatory responses that partly involved in the phosphorylation expression level of MAPK signal pathway in RAW264.7 cells exposed to acute stress.

Immune checkpoints are the crucial regulators of immune system and play essential roles in maintaining self-tolerance, preventing autoimmune responses, and minimizing tissue damage by regulating the duration and intensity of the immune response. Furthermore, immune checkpoints are usually overexpressed in cancer cells or noninvasive cells in tumor tissues and are capable of suppressing the antitumor response. Based on substantial physiological analyses as well as preclinical and clinical studies, checkpoint molecules have been evaluated as potential therapeutic targets for the treatment of multiple types of cancers. In the last few years, extensive evidence has supported the immunoregulatory effects of traditional Chinese medicines (TCMs). The main advantage of TCMs and natural medicine is that they usually contain multiple active components, which can act on multiple targets at the same time, resulting in additive or synergistic effects. The strong immune regulation function of traditional Chinese medicine on immune checkpoints has also been of great interest. For example,

The mortality rate of liver cancer patients in China is increasing constantly, which greatly threatens human health, and therefore, it is urgent to explore more effective treatment methods to prolong the survival time of patients. Because of its special physiological structure, the liver plays an immunoregulatory role, and thus immunotherapy for liver cancer gradually shows its clinical advantages and has become the fourth-generation therapy for liver cancer after surgical resection, chemotherapy, and radiotherapy. Adoptive cell transfer immunotherapy has been developed rapidly in the treatment of hepatocellular carcinoma (HCC) in recent years. CIK, NK, DC-CIK, TIL, and CAR-T cells are immune cells used for adoptive cell transfer immunotherapy. This article briefly summarizes the research advances in these immune cells in the treatment of HCC.
