Diabetic cardiomyopathy ( DC) is an independent complication of diabetes mellitus accompanied with cardiac metabolic imbalances ( increase of fatty acids and reduction of glucose) ,which would impair cardiac function and structure seriously. Peroxisome proliferator-activated receptors ( PPARs) are ligand-activated transcription factors belonging to the nuclear hormone receptor superfamily,and they could transcriptionally regulate energy metabolism and function. PPARs also play an important role in regulating metabolism in DC heart,and directly or indirectly affect cardiac function and structure.

Objective To evaluate the effect of injecting transplantation of autologous fat granules in the treatment of soft tissue depression in face. Methods Autologous subcutaneous fat granules were obtained by liposuction and implanted into the facial sites of soft tissue depression by injection. Results From 1996 to 2002, 56 affected sites were treated, in which 45 sites were given fat granule injection once and 11 sites twice. The volume of fat granules ranged from 1.5ml to 24ml with an average of 8.9ml. Among the 43 sites in 28 cases followed up for more than 6 months, including 8 sites (18.6%) treated twice, 38 ones showed excellent or good augmentation results for 6 months, the percentage being 88.4%. No serious complications occurred. Conclusions Local injecting transplantation of autologous fat granules is effective for correcting the simple soft tissue depression in face. Repeated injections may be needed in some cases. The procedure is simple, safe and minimally invasive.

Objective To investigate the state of the art technique of ectropion correction. Methods Orbicularis oculi myocutaneous flap on both upper and lower eyelids was used to correct ectropion. Results From Feb.1994～June 2001, the authors performed correction of ectropion for 24 patients. Among them 19 patients were followed up, and the period of follow-up ranged from 3 weeks to 2 years. All of the followed patients received good results except one who had partial necrosis of the orbicularis oculi myocutaneous flap. Conclusion Orbicularis oculi myocutaneous flap has a rich blood circulation. The ratio of its length and width can be made to be 6∶1, and its contour can be trimmed as one's will. In addition, the flap can be transferred flexibly, and the incision in donor site is hidden in nature wrinkle. With this flap, the ectropion can be repaired as an aesthetic unit in one stage.

Objective To evaluate the application of three-dimensional (3D) scanning in the measurements and analyses of breast morphology changes that occur after breast augmentation. Methods Pre- and postoperative breast 3D images were obtained in 18 patients (36 breasts) undergoing augmentation mammaplasty by 3D scanning. All implants were round sillicone and planted under pectoral muscle. Average implant volume was 232.2 mL, and average projection was 3.46 cm. The number of implants in low profile implant group was 12( h ＜ 3.0 cm), and 16 in moderate group ( 3.0 ≤ h ＜ 4.0 cm), 8 in high group ( h ≥ 4.0 cm). The following parameters were measured by Geomagic 10.0: volume, projection, angle and distance of key landmarks, and symmetry degree. Results The increased volume of breast was corresponding with the implant volume (P ＞0.05). Postoperative breast projection was 12.9 %, less than expected projection (preoperative + implant projection). The values in low, moderate, and high profile group were 5.2 %, 15.1%, and 20.2 %,respectively. Conclusion 3D scanning is a quick, convenient, accurate and non-contact method for measurement of breast morphology, and it is promising in breast plastic surgery in the future.

Objective To investigate the relative histological change of transplanted domestic expanded polytetrafluoroethylene (e-PTFE), which were treated with different methods, in order to offer the referential data for clinical application. Methods e-PTFE treated with different methods was transplanted into subcutaneous tussue of rat. The samples harvested according to time sequence were examined by using histological and histochemical methods. Dynamic change of the structure between the e-PTFE and it's surrounded tissue was investigated based on the examination. Results Cell and tissue were observed on the inside of all the e-PTFE including the control group and the experiment groups. Heavy cell infiltration on the 3rd day was the most significant in control group, and the quantity of tissue ingrowth was also the most until the 28th day. The next was trimming group. The quantity of both cell infiltration and the tissue ingrowth in high pressure steamed group and forceps squeezed group were less than that in other groups. Conclusion Cell infiltration into domestic e-PTFE is significantly achieved since 72 hrs and fibrovascular ingrowth since the 7days after implanted e-PTFE under subcutaneous tissue of the rat. Different treatment methods of e-PTFE can affect the speed of tissue ingrowth into the e-PTFE, which could be a reference for clinic application of e-PTFE.

BACKGROUND:Wear particles-induced osteoblasts apoptosis in vitro has been documented in many studies. However, the apoptosis of osteoblasts in osteolytic bone tissue and the selective mechanisms involved in the pathogenesis of osteolysis have been studied rarely.
OBJECTIVE:To investigate the influence of endoplasmic reticulum (ER) stress on the apoptosis of osteoblasts in osteolytic bone tissue and osteolysis progression.
METHODS:The mouse model of osteolysis was induced with wear particles placed onto the calvaria. The experiment was divided into four groups:blank control group (PBS stimulation);wear particle group (nano-al oy powder suspension stimulation);ER stress positive control group (nano-al oy powder+thapsin stimulation);and ER stress inhibitor group (nano-al oy powder+sodium 4-phenylbutyrate stimulation). The histopathologic change of osteolysis was assessed by hematoxylin-eosin, toluidine blue and alkaline phosphatase staining. Osteoblast proliferation and differentiation in osteolytic craniums were measured. The expression of ER stress markers in osteolytic craniums was examined by western blot analysis. Osteoblast apoptosis was analyzed by TUNEL staining and immunohistochemistry of Caspase-3 in osteolytic craniums.
RESULTS AND CONCLUSION:Wear particles were capable of inducing osteolysis, aggravating the infiltration of inflammatory cells, and inhibiting the differentiation of osteoblasts in osteolytic craniums. Meanwhile wear particles upregulated the ER stress markers and promote the apoptosis in osteolytic craniums. Blocking ER stress with sodium 4-phenylbutyrate dramatical y reduced the severity of osteolysis, significantly reduced bone invasion and inflammatory infiltration, promoted the differentiation of osteoblasts, and dramatical y reduced the apoptosis. Along with apoptosis, the expression of ER stress marker was decreased. The present study suggests that the ER stress may be crucial for osteolysis and represent a potential therapeutic target in the prevention and treatment of patients with total joint replacement who are at high risk of early aseptic loosening development.

Objective To study the real-time gait behavioral changes in rat models of experimental diabetic peripheral neuropathy.Methods Twenty-five SPF Sprague-Dawley rats were randomly divided into experimental group ( 6 males and 7 females) and control group (6 males and 6 females).Diabetes was induced in rats by intraperitoneal injection of streptozotocin ( STZ ) in a dose of 45 mg/kg.The gait behavior in all rats was tested at 12 weeks after diabetes modelling.Results Compared with the control group, the rats with diabetic peripheral neuropathy showed statistically significant different walk cycle extension, walk speed, average print intensity, balance and coordination.The abnormal gait behavior of the rat models was mainly reflected in the increased average and each foot walk cycle extension ( P<0.01 ) , average intensity (P<0.05), absolute average body rotation (P<0.01),and shortened both homologous coupling and homolateral coupling( P <0.05 ) .Conclusions Experimental rat models of diabetic peripheral neuropathy can exhibit obvious changes of gait behavior, and may provide a reference for related clinical and basic research.
