ABSTRACT
Ginseng Radix et Rhizoma（GRR） has the function of replenishing vital energy and can lighten the body and prolong the life when taken for a long time， which is suitable for the development of anti-aging products， so this paper intends to sort out the progress of anti-aging research on GRR. After combing， the results of modern studies have shown that a variety of components in GRR have anti-aging effect， which can prolong the lifespan of aging animal models， as well as delay the aging of various systems. The anti-aging mechanisms mainly include anti-cellular senescence， anti-oxidative stress， inhibiting telomere shortening， maintaining mitochondrial homeostasis and so on. The anti-aging ingredients of GRR involved in the researches mainly include ginsenoside Rg1 and ginsenoside Rb1， in addition， ginsenoside Rg3， ginsenoside Rd， ginsenoside Rg2， ginsenoside Re， ginsenoside Rb2， oligosaccharides of GRR， polysaccharides of GRR， water extract of GRR， total saponins of Panax ginseng stems and leaves are also included. Therefore， under current background of population aging， the in-depth development of GRR and its transformation into anti-aging products are of great significance for delaying senility and improving the health conditions of aging population.
ABSTRACT
Objective To introduce a safe and practical approach for the treatment of severe muscular torticollis. Methods In an axis of the spasmodic sternocleidomastoid muscle, the author designed a five-valve flap with two valvae inside, which ended at the mastoid point and inferior clavicular part of sternocleidomastoid muscle, respectively. The arm length of each valve was approximately half of its axis. Each valve was separated bluntly in naked eyes in order not to detach the platysma myoides from the skin, and to release the webbed neck. Under the flap, the thinned and fibrosed sternocleidomastoid muscle and spasmodic neck sheath and superficial cervical vein were easily found. The sternocleidomastoid muscle was disconnected at the median point, and the two ends were retracted, the superficial cervical vein was cut and ligated, the neck sheath was released to uncover the spasmodic cervical artery and nerve. The head was right positioned, and then the surrounded fascial tissues were released under the protection of the arteries and veins. The flap was sutured to cover the arteries, veins and muscles. Results Reasonably good effect was achieved in one case and intermediate effects in other 4 cases. Surgical results were satisfactory. All the flaps were survival with insignificant scar formation. Conclusions Webbed skin deformity in the neck can be corrected by using five-valve plastic surgery of platysma myoides, which is able to cover the exposed nerves and vessels. This procedure prevents the adhesion of the operated area, ensures the blood supply of the distal portion of the flap, and also avoids the damage of other tissues in the flap area.
