Methods The tumescent technique formulas were present and analysed through 318 cases of ultrosonic liposuction. Results The following regimen was recommended as a result of the above studies: Lactated Ringer's solution or nosmal sodium was the fluid of choice; Lidocaine (500 mg/l) was a reference anesthetic. The maximal safe dose recommended for liposuction was 35 mg/kg body weight and total dose of epinephrine was 2～3 mg/l. But its concentation should be lower than 1:1 000 000. Concentration of sodium bicarbonate was 500 mg/l, and higer doses were of no value but harmless. Conclusions Safer formulas are provided for the tumescent technique administration in the ultrosonic liposuction. The tumescent technique may reduce potential complications related to ultrosonic liposuction

Objective To explore and solve the repairing and reconstruction in leg serious damage.Methods Using microsurgical technique to reconstruct 9 cases leg serious defection,especially free combining flap with two area flap were applied in 4 cases,two set of vessel were anastomosised to repair the tremendous defection with deep tissue including in tendon, vessel, nerve injury and exposure. Another 5 cases were repaired with paraumbilical flap with opposite lateral vessel anastomosis. Results All 9 cases were applied successfully with 100%survived and were followed-up for one month to four vears. all flaps were good and appearance was excellent,and there were satisfied function recovery. Conclusion It is better choice for repairing complex tissue defection in leg by combining giant free flap transplantation and it is also reliable method for flap circulation by opposite lateral vessel anastomosis.

Objective To study the effect of topical tacrolimus (FK506) on the survival of the xenogeneic transplanted hair follicles from human scalp to Wistar rats. Methods In our study, Wistar rats were used as recipients and human as donor. The black hair follicles of human scalp were harvested, and then the xenogeneic grafts were transplanted to white Wistar rats on the back. 20 couples of rats were divided in 2 groups: topical tacrolimus group (group A), and blank control group (group B). After operaton, we compared the survival time of hair follicles and their histologic outcomes in order to verify the practicability of xenogeneic transplantion of hair follicles, and the topical application of tacrolimus results.Results The mean survival time of group A was longer [(49. 9 ±7. 1) days] as compared to group B [(13. 1±1. 2) days]. The longest survival time was 65 days in group A and 14 days in group B, respectively. By comparison of the results we found that topical tacrolimus prolonged the survival time of the xenotransplanted hair follicles significantly and that tropical medication could not avoid rejection. Conclusions The immune privilege function dependent on the hair follicle anagen and axillary topical tacrolimus, can prolong the survival time of the xenogeneic transplanted hair follicles in rats significantly.

OBJECTIVETo assess the outcome of large facial defect reconstruction with "partition" pre-expanded cervico-scapulo-dorsal flaps (CSDF) based on the superficial cervical artery (SCA).

METHODSSurgical course consisted of 3 stages. In stage I, a skin flap was designed along the axis of SCA according to the facial defect and an expander was implanted in the cervico-scapulo-dorsal region by means of "partition" expansion. The expanders were implanted beside the flap axis and beneath the posterior half of flaps so as to expand only half area of the flap. During the stage II, expanders were injected with saline regularly for continuous expansion. In stage III, the pre-expanded CSDFs were transferred to cover the facial defect of which the CSDFs included about half of non-expanded area.

RESULTSFrom November of 2008 to December of 2013, 15 patients with facial hypertrophic scar or scar contracture were reconstructed with pre-expanded CSDF based on the SCA. The expansion lasted for 3 to 4 months, and the expanded volume varied from 680 to 960 ml. One case of 4.0 cm x 1.5 cm epidermal flap necrosis occurred and healed subsequently with superficial scar; and another case of blister formation in the distal part of flap was found, which recovered without scar; the other 13 flaps survived without complications. After a follow-up for 12 to 38 months( average 26. 2 months), patients regained satisfactory appearance of face, with no obvious hypertrophic scar in the donor site.

CONCLUSIONSPartition preexpanded CSDF based on the SCA is a good choice for large facial defect reconstruction, and the partition expansion is an effective strategy for prevention of venous congestion.
