ABSTRACT
As a novel,label-free and non-invasive detection modality,terahertz(THz,1THz=1012 Hz)spectroscopy has been widely used in various areas.For instance,in the biomedical field,it has great potentials to provide real-time scanning of living cells and tissues due to its unique advantages.Significant achievements have been reached in cell detection, related to bacterial identification, cancer cell characterization and blood cell detection.In tissue detection, the THz spectroscopy can be used to provide real-time scanning of living tissues and fast diagnosis.Furthermore, a single system which integrated THz spectroscopy and THz imaging would be able to collect information more sensitive and comprehensive. However,the clinical adaption of THz spectroscopy is still a controversial issue attributed to some intrinsic limitations and technical bottlenecks.In this article, both the application of THz spectroscopy in cell and tissue detection and the existing challenges and strategies to accelerate clinical applications were reviewed comprehensively.
ABSTRACT
With the rapid development of instrument technology , Raman spectrometer has become one of the fastest growing type of instrument in the molecular spectroscopy . In recent years , Raman spectrometer gradually emerging in the application in the domain of biology and medicine , Raman spectroscopy technology appears new development constantly in the rapid identification and classification of microorganisms because of its rapid , efficient, sensitive, noninvasive, repeatability and other unique advantages.This article describes its application in the rapid detection of bacteria , viruses and other microorganisms , and also prospects for the application of Raman spectroscopy in future clinical work .
ABSTRACT
OBJECTIVE:To observe the clinical efficacy of metadoxine combined with tiopronin in the treatment of alcoholic liver disease.METHODS:In retrospective study,70 patients with alcoholic liver disease were selected from Shanxi Provincial People's Hospital and Taiyuan Third People's Hospital during Oct.2013-Dec.2015,and then divided into treatment group and control group with 35 cases in each group according to therapy plan.Control group was additionally given Tiopronin enteric-coated tablet 0.2 g,po,tid,based on routine treatment;treatment groups was additionally Metadoxine tablet 1.0 g,po,bid,on the basis of control group.Both groups received treatment for 6 weeks.Serum indicators as ALT,AST,γ-GT,TBIL,TC,TG and A/G and serum hepatic fibrosis indicators as Ⅳ-C,HA and Ln were observed in 2 groups before and after treatment as well as the diameters of MPV and SPV,spleen thickness and clinical efficacy.The occurrence of ADR was recorded.RESULTS:The serum levels of ALT,AST,y-GT,TBIL,TC and TG were decreased significantly in 2 groups,while A/G level was increased significantly;above indicators of treatment group were more significant than those of control group,with statistical significance (P＜0.05).Serum levels of Ⅳ-C,HA,Ln,MPV,SPV and spleen thickness in treatment group were significantly decreased and lower than in control group,with statistical significance (P＜0.05).Total response rate of treatment group (94.29％) was significantly higher than that of control group (62.86％),with statistical significance (P＜0.05).No obvious ADR was found in 2 groups.CONCLUSIONS:Metadoxine combined with tiopronin shows good therapeutic efficacy for alcoholic liver disease with good safety.
