ABSTRACT

3D SHINKEI neurography is a new sequence for imaging the peripheral nerves. The study aims at assessing traumatic brachial plexus injury using this sequence. Fifty-eight patients with suspected trauma induced brachial plexus injury underwent MR neurography (MRN) imaging in 3D SHINKEI sequence at 3 T. Surgery and intraoperative somatosensory evoked potentials or clinical follow-up results were used as the reference standard. MRN, surgery and electromyography (EMG) findings were recorded at four levels of the brachial plexus-roots, trunks, cords and branches. Fifty-eight patients had pre- or postganglionic injury. The C5-C6 nerve postganglionic segment was the most common (average 42%) among the postganglionic injuries detected by 3D SHINKEI MRN. The diagnostic accuracy (83.75%) and the specificity (90.30%) of MRN higher than that of EMG (p < 0.001). There was no significant difference in the diagnostic sensitivity of MRN compared with EMG (p > 0.05). Eighteen patients with brachial plexus injury underwent surgical exploration after MRN examination and the correlation between MRN and surgery was 66.7%. Due to the high diagnostic accuracy and specificity, 3D SHINKEI MRN can comprehensively display the traumatic brachial plexus injury. This sequence has great potential in the accurate diagnosis of traumatic brachial plexus injury.

ABSTRACT

Pelvic inflammatory disease( PID) rat model was induced by the mixture of Escherichia coli,Staphylococcus aureus,and Streptococcus hemolytic-ß. Gas chromatography-mass spectrometry( GC-MS) based metabolic profiling method was combined with multivariate statistical analysis,such as PCA,PLS-DA and OPLS-DA to analyze endogenous small molecule metabolites in serum of rats after treatment of Fuke Qianjin Capsules. The results showed that Fuke Qianjin Capsules could significantly improve the inflammatory pathological characteristics and tissue damages in model rats. Based on the principle of VIP>1 and P<0. 05,a total of 6 different metabolic biomarkers were identified,including L-valine,L-isoleucine,L-threonine,butanedioic acid,serine and D-glucose,respectively.The contents of these six different metabolites were significantly reversed after administration. Further analysis of the metabolite pathways through KEGG database showed that Fuke Qianjin Capsules achieved the effect possibly through glycine,serine and threonine metabolism,aminoacyl-tRNA biosynthesis and valine,leucine and isoleucine biosynthesis. Therefore,this study came to the conclusion that Fuke Qianjin Capsules can be used in the treatment of mixed bacteria induced pelvic inflammatory disease possibly by regulating amino acid and its derivative metabolism.
