Objective@#To investigate the clinical efficacy of circumferential thigh liposuction with three incisions in thigh.@*Methods@#From April 2017 to October 2018, 31 patients received circumferential thigh liposuction with three incisions. All patients were females at 17-42 years old, with the mean age of 25.6± 0.8 years. An incision was designed in the pubic area, two in right and left inferior gluteal folds respectively. After injecting tumescent liquid into operation area, blunt and bent cannulas with 2.5-3.5 mm in diameter and 20-45 cm in length were used to extract deep subcutaneous fat, but 0.5 cm thick subcutaneous superficial fat was preserved. Elastic pants were dressed for 3 months after surgery. The thigh contour improvement was evaluated by the patients and 2 doctors.@*Results@#All the patients recovered uneventfully, without complications of fat embolism or infection. Satisfaction ratios of overall thigh and inner thigh contour increased from 81.7% to 80.6%, evaluated by patients. Ten patients completed postoperative outpatient revisit after 2 months. Satisfaction ratios of overall thigh and inner thigh contour increased from 80% to 75%, evaluated by doctors.@*Conclusion@#Three-incision circumferential thigh liposuction is an effective method in thigh contouring with concealed incision scar.
ABSTRACT
Objective@#To investigate the clinical efficacy and safety profile of hyaluronic acid dermal filler(Restylane®) in treating nasolabial folds in Chinese population.@*Methods@#103 subjects in this study were recruited from five Chinese clinical trial centers between July 2014 and December 2015. Subjects were treated with hyaluronic acid dermal filler in correcting nasolabial folds and an optional re-treatment was performed after 12 months according to the subjects′wishes. The improved of nasolabial folds was evaluated by the change of severity (wrinkle severity rating scale, WSRS) and aesthetic improvement (global aesthetic improvement scale, GAIS). Satisfaction of subjects on treatment was evaluated using subject satisfaction questionnaires (SSQ). Safety indicators such as pain, skin and soft tissue presentation at the injection site were continuously evaluated throughout the whole treatment process.@*Results@#Significant improvement in scores of WSRS and GAIS of all subjects was observed after treatment. Nine months after treatment, the scores of WSRS in 80 subjects (77.7%) and GAIS in 96 subjects (93.2%) were still improved. The 68 subjects (95.8%) received re-treatment after 12 months gained further improvement in nasolabial folds. Most adverse events were mild or moderate (transient/reversible local manifestations) and all resolved before study end, no severe adverse event related to products observed.@*Conclusions@#Hyaluronic acid dermal filler is effective and safe in treatment of nasolabial folds in Chinese population and the effect can last up to 12 months.
ABSTRACT
Objective@#To explore the clinical effect of cervico-acromial fasciocutaneous flap based on the supraclavicular artery as a method for face and neck reconstruction.@*Methods@#From Oct 1990 to June 2014, 17 patients, with the age range of 7 to 51 years, suffering from cicatricle contractures of neck or facial defect, were treated with cervico-acromial fascicutaneous flaps. 29 flaps were used in 12 patients bilaterally or multiply. The donor sites of 2 patients were closed by skin graft; while in the rest 15 patients, the donor sites were closed by expanded flaps.@*Results@#All the 29 flaps were survived, with satisfactory color and texture. Hematoma occurred in 1 case after tissue expander implantation, but the flap was successfully expanded after evacuation of hematoma. The size of flaps ranged from 15 cm×7 cm to 35 cm×15 cm. 10 patients completed 6 months follow-up, and presented with satisfactory appearance and better functional results.@*Conclusions@#Cervico-acromial fascicutaneous flap based on the supraclavicular artery is an good choice for reconstruction of neck and facial defects.
ABSTRACT
Objective@#To observe the safety and efficiency of face-lift combined with fat grafting in facial rejuvenation.@*Methods@#We performed a retrospective study, which included 23 patients. SMAS suspension and multi-site suspension were combined to correct the nasolabial fold, mid-cheek aging and malar mounds. Structural fat grafting was performed to treat the volume loss in mid-face.@*Results@#All patients demonstrated a significant improvement in midfacial appearance. No infection or nerve injury were found in this study. Only three patients did not get primary healing in temple region, which led to temporal hair loss from secondary healing.@*Conclusions@#This study demonstrates that fat grafting and multiple layers face-lift are efficient method for facial rejuvenation. These approaches appear to be very promising for facial anti-aging techniques.
ABSTRACT
Objective To study the effect of PIM-1 gene silence by RNA interference (RNAi) on the growth of human prostate cancer xenograft tumor in nude mice. Methods The xenograft tumor model of human prostate cancer was established by injecting PC-3 cells in armpits of 12 nude mice. After modeling, the nude mice were randomly divided into three groups: interference plasmid group (injecting with RNAi recombinant plasmid), empty plasmid group and negative control group (liposome every), 4 mice in each group. Mice were injected every 2 days for 5 times. The tumor volumes of xenografts were measured during experiment, and the curve of tumor growth was drawn accordingly. The quality of tumor was measured, and the inhibitory rate of tumor was calculated at the end of the experiments. The expression levels of PIM-1, c-MYC mRNA and protein in xenograft tumors were detected by real-time PCR and Western blot assay, respectively. Furthermore, immunohistochemistry staining was used to verify the expression of PIM-1. Results The xenograft tumor model of human prostate cancer was established successfully. The volume of tumor was significantly decreased 6 days after the injection treatment in interference plasmid group than that of empty plasmid group and negative control group. The effect of suppressing tumor growth was remarkable. The expression levels of PIM-1 mRNA and protein were down-regulated significantly in interference plasmid group than those of other two groups. The immunohistochemical staining of PIM-1 showed the same changes. There was no significant difference in c-MYC protein level between the three groups. But interestingly, the c-MYC mRNA level was significantly decreased in interference plasmid group than that of other two groups. Conclusion The silence of PIM-1 gene by RNAi recombinant plasmid can result a significant growth suppression of the human prostate cancer xenograft tumors in nude mice. The expression of c-MYC gene is down-regulated at translation level in the therapeutic group concomitantly. PIM-1 may be a promising target of gene therapy for prostate cancer.
ABSTRACT
<p><b>OBJECTIVE</b>Augmentation rhinoplasty is a commonly procedure in clinical work for a plastic surgeon. Autologous costal cartilage is widely used in aesthetic rhinoplasy because of the abundant in quality. However, the cartilage may warp, and it is not easy-handling for inexperienced plastic surgeons. We-used diced cartilage combined with thin strips as columellar struts, which can be easily shaped, and reduce the warping incidence.</p><p><b>METHODS</b>From July 2012 to March 2014, 61 patients were performed diced costal cartilage for nasal augmentation via endonasal approach. Standardized photographs are obtained before and after surgery. Postoperative outcome is graded by patient's self-evaluation of the nasal appearance with a satisfaction scale.</p><p><b>RESULTS</b>Among the 61 cases, 25 were revision cases. The follow-up time was no less than 6 months, with an average time of 10.9 months. 28 patients reported improved or better nasal appearance. One patient required revision surgery because of overcorrection. Supratip step-off was observed in one patient and corrected by external reshaping. No warping, infection, irregularity, absorption, airway obstruction, or donor-site morbidity were observed. All patients were satisfied with the final appearance.</p><p><b>CONCLUSIONS</b>Diced costal cartilage is a reliable option for nasal augmentation and revision rhinoplasty. Good outcomes can be achieved postoperatively, with aesthetically pleasing appearance and simple procedure.</p>

Cancer pain seriously affects the quality of life of patients and could disturb normal cancer treatment. Therefore, ap-propriate drugs should be chosen to control the pain. Transdermal fentanyl is a type of potent opioid that is widely used in controlling moderate and severe cancer pains. This paper reviews the pharmacological characteristics of transdermal fentanyl and its clinical appli-cation in cancer pain management.
ABSTRACT
Long noncoding RNA (lncRNA) comprises a group of RNAs that are longer than 200 nucleotides. The lncRNA does not contain functional open reading frames and cannot encode proteins. RNA accounts for a large proportion in the total noncoding RNAs. The number, type, and function of lncRNA are unclear, so they have been called the dark matter of the genome. With the applica-tion of a new generation of gene sequencing technology, lncRNA is found to be involved in the mechanisms mediating the signal trans-duction pathway, regulating the cell cycle, and inducing cell apoptosis. In this article, the authors summarized the up-to-date research progress on lncRNA in digestive system neoplasms in China and overseas to provide new insights into the genetic diagnosis and treat-ment of digestive system neoplasms in clinics.

ABSTRACT
Objective To observe the efficiency of infection of adenovirus containing hepatocyte growth factor(Ad-HGF) on adipose derived stem cells and to prove whether the valid HGF can appear after infection and the multiplicity of infection. Methods We use the digestion separation method and the attachingwall characteristic of the adipose-derived stem cells to separate the human adipose-derived stem cells. Adipose-derived stem cells were infected by the vector of adenovirus (Ad-GFP) which carries the GFP gene,and the GFP acts as the indicating gene to determine the infection efficiency of recombinant adenovirus to adipose- derived stem cells. HGF-ELISA was used to detect HGF as expression-secretion. Results The adherent cells displayed themselves as fibroblast in morphology. The primary cultured cells fusion can arrive to 70% - 80% in 7 - 10 days. The infected HGF can be highly expressed in 48hours. Conclusion Adenovirus can meditate the expression of HGF gene in adipose-derived stem cells effectively.

ABSTRACT
This paper aims to prepare polyanhydride-Pirarubicin dose long-acting sustained-release implants for the treatment of bladder cancer and for the prevention of postoperative recurrence of bladder cancer. Pirarubicin hydrochloride (THP) and polyanhydride, in accordance with a certain proportion, were fully mixed in the agate morta and dissolved in dichloromethane, and then were cast into a film within a mold put in the dryer set at 4 degrees C. Each tablet implanted contained 5.0 mg of THP. Polyanhydride-pirarubicin sustained-release was implanted into the bladder mucosa of the rabbits, and blood and urine samples were taken at different times after the operation. The THP drug concentrations in urine and blood were determined with high-performance liquid chromatography. The THP concentration in urine was significantly higher than the THP concentration in plasma. The drug concentration in urine reached (92.5 +/- 7.4) microg/L at 250 d time after the operation. Polyanhydride-pirarubicin implants possess long-acting sustained-release level dynamics in the body. It can maintain a stable long-term drug release and can be expected to last a year and can effectively prevent recurrence of bladder cancer. The present experiments proved that the implants with sustained-release drug treatment are expected to be useful in the clinical application in prevention of bladder cancer recurrence.
