ObjectiveTo investigate the value of MRI in the diagnosis of cavernous transformation of the portal vein (CTPV).MethodsPlain MRI,dynamic enhanced and (or) dynamic contrast enhanced magnetic resonance angiography(DCE-MRA) findings in 30 patients of clinical-proved CTPV were retrospectively analyzed.ResultsAmong 30 CTPV patients on plain MRI,obliteration of main and (or) branched portal vein were found,and mass-like or reticular abnormal soft-tissue signals were around the vein,which were produced by collateral vessels.On dynamic enhanced MRI,abnormal hepatic perfusion during arterial phase and abnormal enhanced collateral veins during portal phase could be seen.The above signs became more obvious on DCE-MRA.ConclusionsMRI and DCE-MRA can clearly visualize the anatomical features of CTPV.It is important and can provide the reliable evidence for planning properly therapeutic protocol to recognize and directly evaluate the CTPV.

Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

Traditional Chinese medicine Polygoni Multiflori Radix is dried roots of Polygonaceae Polygortum multiflorum Thunb. Its clinical application records were first discovered in literatures of the Tang dynasty. The origins, efficacy, toxicity, processing and taboos of Polygoni Multiflori Radix have been discussed in many ancient herb literatures. In recent years, with the increase in the public awareness in health, Polygoni Multiflori Radix admits preparations have been more widely applied in the treatment and prevention of diseases. However, there have been more and more reports about Polygoni Multiflori Radix induced liver injury, the safety of Polygoni Multiflori Radix has increasingly attracted attention of the society. In this paper, the authors summarized and analyzed the toxicity and medication risk factors of Polygoni Multiflori Radix recorded in ancient herb literatures, and proposed that more attention shall be given to the effect of the planting and processing methods on the components and toxicity of Polygoni Multiflori Radix in safety studies, which provides clues for the further studies.

The renal toxicity and mutagenicity of aristolochic acid (AA) as well as its carcinogenicity on upper urinary tract transitional epithelial cells have been widely known. Since 2003, drug regulatory departments have successively cancelled the quality standards for AA-containing medicines such as Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolchiae Fangchi Radix, and adopted measures for strengthening regulation and revising package insert or quality standards for other AA-containing medicines, including Aristolochia Cinnabarina Radix, Aristolochiae Fructus, Aristolochiae Mollissimae Herba, in order to control its safety risk. In recent years, domestic and foreign studies on AA have mainly involved action mechanism and clinical performance of AA toxicity, early-stage diagnosis and treatment method. In this paper, authors gave a brief summary and evaluation on risk factors for using AA-containing medicines, and offered measures and suggestions for preventing and controlling AA toxicity.

The adverse reaction monitoring is important in warning the risks of traditional Chinese medicines at an early stage, finding potential quality problems and ensuring the safe clinical medication. In the study, efforts were made to investigate the risk signal mining techniques in line with the characteristics of traditional Chinese medicines, particularly the complexity in component, processing, compatibility, preparation and clinical medication, find early risk signals of traditional Chinese medicines and establish a traditional Chinese medicine safety evaluation system based on adverse reaction risk signals, in order to improve the target studies on traditional Chinese medicine safety, effective and timely control risks and solve the existing frequent safety issue in traditional Chinese medicines.

Post-marketing evaluation is a process which evaluate the risks and benefits of drug clinical application comprehensively and systematically, scientific and systematic results of post-marketing evaluation not only can provide data support for clinical application of traditional Chinese medicine, but also can be a reliable basis for the supervision department to develop risk control measures. With the increasing demands for treatment and prevention of disease, traditional Chinese medicine has been widely used, and security issues are also exposed. How to find risk signal of traditional Chinese medicine in the early stages, carry out targeted evaluation work and control risk timely have become challenges in the development of traditional Chinese medicine industry.
