Object To study the effects of WUZI SIWU GUASHITANG (WT) against multi glycosides of Tripterygium wilfordii Hook. f. (GTW) induced genital system toxicity in male rats and its mechanism. Methods Male rats in treatment groups were treated respectively with a 80 days oral administration of large , middle and small doses of WT plus a fixed dose of GTW. The rats as control were treated with GTW alone or saline. Thereafter, the changes in testis organ index, the number of spermatozoa, the rate of movable spermatozoa and the structure of spermatogenic cell epithlium were observed and the serum testosterone level was determined by IRMA. Then the comparison was made between treatment and control groups as to above variables. Results As compared with GTW group, large or middle dose of WT significantly increased the weight of testis, the number of spermatozoa and the rate of movable spermatozoa. Large dose of WT could relieve the damage of GTW to the spermatogenic cell epithelium completely and keep the serum testosterone at normal level. Conclusion The combined use of GTW with WT is very useful in relief of GTW induced adverse reactions of genital system in male rats. The mechanism by which WT exerts the counteractive effects is related to protecting the spermatogenic cell epithelium from being damaged by GTW, and keeping the serum testosterone at normal level.

Objective To study one simple, safe and effective method of periorbital rhytidectomy. Methods With turgescent anesthesia, 1 cm -extent was dissected laterally deep under musculus orbicularis oculi at the approach of eyebrow area. The musculus orbicularis oculi was fixed to the deep temporal fascia and frontal periosteum. The superciliary corrugator muscle and depressor muscle were exposured and cut. Then the eyelid blepharoalasty was performed through the skin incision, meanwhile the lateral pars orbitalis muscle was liberated to form an orbitalis muscle flap under the orbitalis muscle and the fat pad, which was fixed to the os orbitale periost by lifting tight to lateral and upper side. For patients with generous pars buccalis and obvious nose lip ditch, the cheekbone fat cushion was also hanged and fixed. Results 65 middle age female patients were followed up for 3～16 months. The scar was no obvious, glabellar wrinkle and canthal wrinkle disappeared at static state, relaxed upper eyelid and eyebrow prolapse reached to complete correct, nasolabial groove wrinkle obvious lessened. 95 % patients were satisfacted with the appearance. Conjunctival edema was found in 4 cases, and disappeared within 1 months. There were no facial nerve injury and other complications. Conclusions It is a new incisional approach that avoids the facial nerves and lessens fossa orbitalis retrogradation. The operative procedure is simple and safe, and its incision is occult. The wound is small and restores rapidly, but the effect is reliable and lasting. It proves to be an ideal approach for face rejuvenation.
