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.

Objective To analyze the nursing effect of the standardized CNP (Clinical nursing pathway) in the hair transplantation surgery during the perioperative period. Method The nursing process of 48 autologous hair transplantation cases in our center would be retrospective analyzed from September 2016 to September 2017. The patients were divided into the control group (24 cases) and experimental group (24 cases), which the former with conventional nursing, the latter with CNP. Afterwards, to study the effect of standardized CNP on hair transplantation according to the statistical analysis of data including the patients'basic information;patient satisfaction;doctors' satisfaction;unit operation time and unit area planting density. Result The results indicated the experimental group with CNP improved the satisfaction of both patients and doctors,meanwhile reducing the opera-tion time and improve the unit area planting density. The application of CNP can improve the nursing process and op-erating results effectively as well as the satisfaction of patients and doctors. It is worthy to be promoted and generalized in clinical treatment.Conclusion The application of CPN could effectively improve the nursing process, as well as the satisfaction of patients and doctors,and improve the overall surgical efficiency. It's worth to be applied in the clinical therapy.

Objective To study the expression of HDAC2 and the correlations with pathological parameters in human tongue squamous cell carcinoma, and to analyze the correlation between them and patients' clinical indicators and survival status.Methods A total of 96 cases of humantongue squamous cell carcinoma (SCC), 24 dysplasia (ED), 13 normal mucosa (NOM) were involved in this study. The expression of HDAC2 was evaluated by ICH. Kaplan-Meier was used to research cumulative surviving of SCC patients.Result Among 96 cases of SCC samples, 86 cases showed positive expression (89.6%), The differences between the overexpression of HDAC2 and the pathological grading, lymph node metastasis, the patient's age and gender were insignificant (all P>0.05). However, the differences of TNM presented statistically significant (χ2 = 18.600, P<0.001). 14 out of 24 ED (58.3%) were positive expression of HDAC2, there were 7 cases (53.8%) of positive expression samples in NOM. The expression of HDAC2 in SCCs was significantly higher than that in ED and NOM (χ2= 118.407, P<0.00). There was no significant difference of cumulative surviving between the positive and negative SCC patients (P = 0.184). However cumulative surviving of patients with lymph node metastasis was significantly shorter than those with no metastasis (P<0.000).Conclusions The expression of HDAC2 in SCC was significantly higher than that in ED and NOM, the TNM stage of patients presented the significant difference of expression of HDAC2, patients with lymph node metastasis were significantly shorter than those with no metastasis, and demonstration can be used as a reliable reference molecule for the evaluating prognosis of SCC.

<p><b>OBJECTIVE</b>To investigate the expression of the human interleukin-1 receptor antagonist (hIL-1ra) in the transfected chondrocytes of temporomandibular joint (TMJ).</p><p><b>METHODS</b>Chondrocytes of TMJ in vitro were transfected by hIL-1ra gene via cationic liposome as a medium. The stable transfected cells were selected by G418. The proliferations of the transduced cell were examined with the growth curve, cell population doubling time. The protein expressing in different periods was detected by immunocytochemistry and enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>The proliferation suppression of gene transfected cells fell significantly with compared to normal cells. The expression of hIL-1ra was detected in the cell plasma and the cell culture supernatant. The highest expression of IL-1ra protein was at the time of 48 hours after gene transfection. The transiently transfected cells were secreted IL-1ra protein continuously 28 days and the stably transduced cells were secreted IL-1ra protein till 72 days.</p><p><b>CONCLUSION</b>This study showed that hIL-1ra protein expressed positively in the cell plasma and the culture supernatant after gene transfection within a certain periods.</p>

<p><b>OBJECTIVE</b>To investigate the variety of proliferating ability of umbilical endothelia (UE) transfected by plasmid pBABE-HYGR-hTERT.</p><p><b>METHODS</b>UE was identified from two aspects: morphology and CD34 labeling technique. The plasmid was obtained and identified by alkali splitting and gel electrophoresis. Liposomes were used to transfect UE. RT-PCR based telomeric repeat amplification protocol (TRAP) assay was used to measure the telomerase activity of endothelia.</p><p><b>RESULTS</b>UE arranged as "cobblestone" and were positive of CD34 labeling. Endothelia transfected by pBABE-HYGR-hTERT(HC) had an raised absorbance of 0.889. The shape of growth curve of HC was similar to UE. But the absorbance of MTT test and the amount of HC were prior to UE at every measuring time and the amount of HC increased four times within 8 days (P < 0.05).</p><p><b>CONCLUSION</b>The transfection of pBABE-HYGRO-hTERT had greatly improved the proliferating abilities and activated the telomerase of UE.</p>
