Review of Anemone raddeana Rhizome and its pharmacological effects / 中国结合医学杂志

The chemical compositions of Anemone raddeana Rhizome, a kind of traditional Chinese medicine, were reviewed, along with its bioactivity and pharmacological properties and method improvements of extracting and detecting triterpenoid saponins. A. raddeana Rhizome is used to treat neuralgia and rheumatism, and is rich in triterpenoid saponins, most of which are pentacyclic, with oleanane as the nucleus. So far, 37 triterpenoid saponins have been determined from the herb. Its reported bioactivity and pharmacological properties have been described as anticancerous, antimicrobial, anti-inflammatory, analgesic, antipyretic, anticonvulsive, antihistaminic, and sedative. It has also been used for the induction of the humoral immune response and treatment of liver fibrosis in chronic hepatitis. However, the herb also has hemolytic effects and can be toxic, which limits its clinical application. Further studies are needed on the pharmaceutical functions, mechanisms, and immunological responses to contribute to the herb's clinical applications.

Clinical application value of laryngeal electromyography and laryngeal somatosensory evoked potential in patients with recurrent laryngeal nerve paralysis by anterior elective cervical surgery / 中国骨伤

<p><b>OBJECTIVE</b>To determine the clinical evaluation role of laryngeal electromyography (LEMG) and laryngeal somatosensory evoked potential (LSEP) in the recurrent laryngeal nerve paralysis by anterior elective cervical surgery.</p><p><b>METHODS</b>LEMG and LSEP were determined in 18 patients with recurrent laryngeal nerve paralysis by anterior elective cervical surgery at the 1st, 2nd and 4th week after operation. The comparison between the normal control (18 health adults) and the results of LEMG and LSEP were analyzed.</p><p><b>RESULTS</b>The latency prolonged and the amplitude decreased of LSEP in all patients as compared with the control group. Furthermore, reinneration potential increased gradually in all patients at the 1st, 2nd and 4th week after operation (P<0.05). The results of LEMG showed increase of denervation potential. The higher the amplitude of LSEP and LEMG, the better the prognosis of the recurrent laryngeal nerve paralysis.</p><p><b>CONCLUSION</b>LEMG and LSEP might evaluate regenerate the degree of recurrent laryngeal nerve injury caused by anterior elective cervical surgery and predict the prognosis of the recurrent laryngeal nerve paralysis.</p>
