OBJECTIVETo investigate the treatment of auricular keloid with dinuclear surgery and intralesional injection of compound Betamethasone.
METHODSFrom Jan. 2008 to Jan. 2012, a total of 186 cases of ear keloid were treated by surgery only (22 cases), or intralesional injection of compound Betamethasone (34 cases), or combined dinuclear surgery with compound Betamethasone (130 cases). All the patients were followed up for one year. SPSS 16.0 software was used for statistical processing and analysis, and GraphPad inspection method for inspection.
RESULTSThe effective rate was 54.55% (12/ 22) in surgery group and 55.88% (19/34)in injection group. The recurrence was obvious in injection group during the follow-up period. The effective rate was as high as 96.92% (126/130) in combined group with recurrence in 4 cases, which was significantly higher than that in other 2 groups (P < 0. 01).
CONCLUSIONCombined dinuclear surgery and compound Betamethasone injection has a good therapeutic effect on auricular keloids.

Objective To explore the role of ADSCs and PRP in soft tissue defect repairing .Methods Harvest adipose tissue from inguinalis fat pad of SD rats ,isolation ,culture ,and identification the ADSCs through three differentiation method .Take 30 male SD rats about 6-7 weeks old randomly .Randomly selected 12 rats been take blood from heart .Preparation the PRP with modi-fied appel method .To count platelet of whole blood and PRP under microscope .Take the remaining rats .Divided the rat into 3 groups(n=6 in each group) randomly ,of which group A treatment with ADSCs and PRP ;Group B treatment with ADSCs ;Group C treatment whit PRP .Selected one side of skin defect wound for test randomly and the relative side skin defect is for control ,Handle all of the control wound to group D ;Observe the grow th of granulation tissue on the wound surface ;observe the inflammatory sur-rounding and the degree about epithelial .statistical analysis and record the wound size ,and calculation the shrinkage rate of wound in different periods .Record the time of completely healing time .Histologic observation of the wound healing tissue .Results Plate-let counting showed platelet of PRP is 5 .21 times than whole blood .The wound completely healed time :group A (18 .25 ± 1 .44 ) days ,group B(19 .13 ± 1 .28)days ,group C(19 .72 ± 0 .87)days ,group D(22 .31 ± 1 .65) days ,The time of each treatment group and control group was significantly obvious(P< 0 .05) .At 3 ,7 ,11 and 15 days after experimental treatment ,compared with the control group the experiment group of wound contraction rate was significantly obvious (P<0 .05) .Conclusion Application of AD-SCs with PRP can enhance the quality and shorten the wound healing time than used them alone .

Objective:To compare the clinical efficacy of autologous fat injection and conjunctival pedicled orbital septal fat grafting for infraorbital margin depression in young people.Methods:Fourty young patients with lower eyelid pouch and infraorbital margin depression with age of 20 to 40 years and average age of 30.6 yaers in the First Affiliated Hospital of Nanchang University from September 2017 to September 2019 were enrolled. According to the surgical method, all patients were divided into 2 groups with 20 cases each. Group 1 underwent transconjunctival orbital septum fat reset. Group 2 underwent various autologous fat injection after proper amount of orbital septal fat being removed, including structural fat, fine-particle fat and nano-fat, performed in different parts and layers. The tear trough rating scale (TTRS) scores and patients' satisfaction at 1 year after operation between 2 groups were compared.Results:Compared with the preoperative TTRS scores, the differences in scores at 6 months and 1 year after surgery were statistically significant ( P<0.01). The scores between two groups were compared at 6 months and 1 year respectively after the operation, and the difference were both statistically significant ( P<0.01). 6 months after the operation, the TTRS scores including four items were carefully compared between the two groups. It showed that the reduction of tear groove depth ( P<0.05), pigmentation ( P<0.01) and wrinkle ( P<0.01) in group 2 were more obvious than those in group 1. The percentage of satisfaction in group 2 (95%) was higher than that in the group 1 (70%), and the difference was statistically significant ( P<0.01). Conclusions:For infraorbital margin depression of young people, after proper amount of orbital septal fat being removed, various free fats graft injection into different parts and layers could obtain better treatment results, reducing not only the depth of the tear groove, but also periorbital pigmentation and fine wrinkles.
