ABSTRACT
BACKGROUND: With the increasing pursuit of beauty, facial cosmetics have become popular, and thereupon various cosmetic methods and surgical methods have emerged. However, high costs, large trauma, slow recovery, permanent scars and even scar hypertrophy can result from these cosmetic surgeries. Transplantation is a relatively new method for facial cosmetics, and the choice of graft is crucial for cosmetic effects. OBJECTIVE: To evaluate the curative effect of facial rejuvenation surgery with structural fat grafting. METHODS: From May 2016 to May 2017, 21 cases of facial rejuvenation were selected. All subjects were assessed for donor sites and affected areas by combining various factors. Fat tissues were isolated from the donor site, and implanted into the affected area after sediment and grease removal. Patient satisfaction and the severity of facial wrinkles were scored through a survey questionnaire. At 6 months after transplantation, the number of request to replenish injections and number of complication cases were statistically recorded. The volume of facial fat tissues in the affected area was calculated before and after transplantation. RESULTS AND CONCLUSION: Two subjects required re-transplantation during the 6-month postoperative follow-up. Facial capacity, depression, and static patterns of all subjects were well improved after one or two autologous fat transplantations. The average satisfaction score on fat transplantation for all the subjects was 8.47±0.43. The volume of facial fat tissues at 6 months after transplantation was significantly increased compared with that before operation (P < 0.05). The postoperative severity of facial wrinkles was significantly lower than before operation (P < 0.05). Only three subjects had complications within 6 months after transplantation, including one case of infection, one of liquefaction and one of fat embolism. V-Line liquid lift with structural fat grafting can effectively improve facial relaxation, sagging and other issues, with a good upgrade of facial rejuvenation effect.
ABSTRACT
Objective To reconstruct the deformity of appearance and function of patients with bone defect, co-cultured system with two stem cells were combined with partial deproteinized biological bone to reconstruct the defect of tibia which is one of the main weight-bearing bone. Methods The bone marrow and peripheral blood were harvested form 18 New Zealand rabbits to isolated bone marrow stem cells and epithelial progenitor cells, and engineering bone was constructed with co-cultured system with these two stem cells and partial deproteinized biological bones; about 1 CM of bone defect of each rabbit was made with bone rongeur, then engineering bones were transplanted into the defect area, the osteogenesis and bone defect recovery were observed on day 14, 28 and month 2.Results The difference of absorbance values of BMSCs group, co-cultured cell group and blank group at each time point and between groups were all statistically significant (P＜0.001), and the collagen content of bone tissue increased gradually after implantation of tissue engineered bone, and the difference between each group was statistically significant (P ＜0.001). The repairment of bone defect with the PDPBB combined with BMSCs and EPCs system has the strongest ability to repair the structure andfunction of the tibial defect area. Conclusion The engineering bone constructed with two stem cells and partial deproteinized bone is a good material for bone defect reconstruction.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of combined reconstruction of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) simultaneously by using allograft patellar tendon under arthroscopy.</p><p><b>METHODS</b>From May 2003 to November 2005, 10 cases of ruptured ACL and PCL were fixated with compressed screws and reconstructed under arthroscopy with allograft patellar tendon simultaneously. The clinical results were evaluated according to IKDC, Lysholm, and Tegner clinical rating scales.</p><p><b>RESULTS</b>All patients were followed up for 12-30 months (mean: 18 months). At the last follow-up, there was no knee extension limitation and knee flexion was between 120 degree and 135 degree,with an average of 128.38 degree. The Lysholm score of the 10 cases was 66.5+/-5.6 before operation and 89.8+/-3.4 at last follow up. The difference was statistically significant (P less than 0.01). The average Tegner activity score decreased from 6.9+/-1.7 (range: 4-9) before injury to 5.5+/-1.6 (rang:2-9) at the follow-up (P equal to 0.53). At the end of follow-up, IKDC score was graded as A in 4 cases (40.0%), B in 5 (50.0%), and C in 1 (10.0%). Of the 10 patients, 8 returned to the same sports level as before injury and 2 were under the level.</p><p><b>CONCLUSION</b>Arthroscopic combined reconstruction of ACL and PCL with allograft patellar tendon has the advantages of minimal trauma in surgery and reliable satisfactory outcome.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical result of arthroscopic anterior cruciate ligament (ACL) reconstruction with either allo- or auto- bone-patellar tendon-bone (B-PT-B) grafts.</p><p><b>METHODS</b>From February 2002 to January 2006, 142 of 187 cases of ACL ruptures who received ACL reconstruction with B-PT-B grafts were studied retrospectively. There were 93 male and 49 female whose age was from 15 to 57 years (mean 26 years). Patients were divided into 2 groups by graft selection: 38 patients with autograft and 104 with allograft. Clinical results were evaluated according to IKDC, Lysholm, Irgang and Larson scales. Sub-items of scales such as pain, swelling and laxity were specifically evaluated.</p><p><b>RESULTS</b>All of the patients were followed up with an average of 24 months (range from 6 to 43 months). All grafts were radiographically in good position at the time of follow-up. KT-1000 examination of affected knee showed less than 3 mm anterior translation difference compared with contralateral one's. Allograft group: 85 patients got normal IKDC score (81.7%). Lysholm score 82.8 +/- 8.5, Irgang score 79.2 +/- 7.3, Larson score 86.7 +/- 3.1. Autograft group: 29 patients got normal IKDC score (76.3%). Lysholm score 84.6 +/- 9.5, Irgang score 79.5 +/- 7.6, Larson score 88.9 +/- 6.8. No significant statistical difference was found between the 2 groups in the comprehend scale (P>0.05).</p><p><b>CONCLUSIONS</b>Both autograft and allograft group achieve good results, and the allograft B-PT-B could provide the similar clinical result as autograft, the preliminary result of allograft reconstruction might indicate predictable result in the future.</p>
