ABSTRACT
Aim To study the antiviral anrl antipyretic mechanism of Phillvrin in vitro and in vivo.Methods By respiratory virus infection cell model, SI index and antiviral activity of forsythia glycosides virus activity in vitro were detected.A mouse model of influenza virus infection was established, and hemagglutination titer, lung index, lung histopathology pathology were detec¬ted.Hemagglutination titer, lung index, lung histopa¬thology pathology were observed and in vivo anti-influ¬enza virus and pneumonia effects were investigated.Dry yeast induced rat fever model was established, temperature and plasma and hypothalamus thermoregu¬lation and inflammation of the related factors were test¬ed , and its antipyretic mechanism was investigated.By AutoDock Vina software for molecular docking, the docking results were plotted with PyMol software.Re¬sults Phillyrin had certain inhibitory effects on H3N2, RSV, E71 , ADV-3, HSV-1 and HSV-2 (SI >2).Phillyrin could reduce hemagglutination titer of infected lung tissue, decrease lung index, and alleviate lung lesions, especially interstitial pneumonia.Phill- vrin could also significantly reduce the body tempera¬ture of rats with fever, and its antipyretic mechanism might he related to the decrease of PGE2 and IL-ip levels in plasma and hypothalamus of rats.Molecular docking results showed that the binding energies of Phillyrin with a-MSH, IL-lp, PEG2, A VP, cAMP and other proteins were all less than - 5 kcal • mol 1.Conclusions Phillyrin has obvious antiviral, antipy-retic and improvement of pulmonary inflammatory le¬sions, and it is speculated that it can play an anti-in¬fluenza effect through "treating both symptoms and root causes".
ABSTRACT
The paper introduces the clinical experience of GAO Hong in treatment of tic disorder. GAO Hong believes that tic disorder results from the primary qi deficiency and mind disturbance. Acupuncture for cultivating the primary and regulating the mind is proposed specially for tic disorder. This acupuncture technique focuses on harmonizing and regulating governor vessel and conception vessel. In clinical practice, the conception vessel acupoints on the abdomen and the governor vessel acupoints on the head are selected particularly, e.g. Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6) and Guanyuan (CV 4) on the abdomen; Baihui (GV 20), Shenting (GV 24), Benshen (GB 13) and Yintang (GV 24+) on the head. The needling sequence and the insertion depth are emphasized, which affect the curative effect and GV 20 is generally punctured first. Besides, considering to the type of disorder and the affected site, tic disorder is treated in view of both syndrome/pattern differentiation and symptom differentiation.
