ABSTRACT
Human hormones at trace levels play a vital role in the regulation of a variety of functions and systems in the body, and an imbalance in hormone levels can lead to the emergence and development of diverse diseases. Therefore, the development of reliable sample pretreatment methods and sensitive and accurate analytical techniques for human hormone detection could contribute to the prevention, diagnosis and treatment of diseases, providing significant improvement for human health. Human samples which are usually used to detecting hormones, such as blood, saliva, urine and other matrix are more complex, so sample pretreatment is an important step to ensure the accuracy and reliability in the detection of hormones. In this review three common sample pretreatment methods including solid phase extraction (SPE), liquid-liquid extraction (LLE) and protein precipitation (PP) methods are discussed. Then, recent research progress in conventional techniques like liquid/gas chromatography and liquid/gas chromatography-mass spectrometry (LC/GC-MS/MS), as well as some novel strategies, such as immunoassay including chemiluminescence immunoassay (CLIA), lateral-flow immunoassay (LFIA) and time-resolved fluoroimmunoassay (TRFIA), and sensor technology including electrochemical (EC), fluorescent (FL) and surface-enhanced Raman scattering (SERS) sensors, and microfluidic chip analysis are discussed for human hormone detection. Finally, the future perspective on the use of these methods for hormone detection is considered. It is hoped to provide powerful insights to researchers for the relevant researches.
ABSTRACT
Xianling Gubao is a common and effective medicine in the treatment of orthopedic diseases. In recent years, it has been reported to be associated with liver injury. However, through the analysis of the adverse drug reaction reports and key hospital cases, we found that there is considerable incomplete information in the reports of Xianling Gubao-related liver injury cases retrieved from the literature. Thus, it is difficult to accurately judge causality between the drug and liver injury. Six cases of liver injury related to Xianling Gubao were identified in key hospitals, two of which achieved the clinical diagnosis according to the assessment of the integrated evidence chain method. We further analyzed the public health data of all residents in Yinzhou. The gross incidence rate of Xianling Gubao-related liver injury was 0.034%, which corresponds to a level of rare incidence. This revealed that Xianling Gubao-related liver injury has significant divergence in individuals and an idiosyncratic nature. The gross incidence of liver injury related to Xianling Gubao was lower than that of other medicines for the treatment of orthopedic diseases. Based on the idiosyncratic drug-induced liver injury model mediated by immune stress, it was found that Epimedii Folium and Psoraleae Fructus were the major components that lead to liver injury, and the liver injury caused by a full prescription was less serious than that encountered with only Epimedii Folium and Psoraleae Fructus. This suggests that the other 4 herbs (Dipsaci Radix, Anemarrhenae Rhizoma, Rehmanniae Radix,Salviae Miltiorrhizae Radix et Rhizoma) can prevent/alleviate the liver injury. Through disassembled prescription analysis, we found that the attenuation efficacy of Salviae Miltiorrhizae Radix et Rhizoma was the most significant. In conclusion, Xianling Gubao may cause idiosyncratic liver injury in a tiny minority of susceptible individuals, but the incidence risk is lower than that of other commonly used drugs for orthopedic disease. Xianling Gubao should be discreetly applied to patients with immune stress. The major components that induced liver injury in Xianling Gubao were Epimedii Folium and Psoraleae Fructus, and Salviae Miltiorrhizae Radix et Rhizoma appears to attenuate this toxicity. This study provides a reference for the rational clinical medication with Xianling Gubao.
