Objective To assess the effect of meal replacements on body weight control and blood glucose and lipid profile by adjusting their nutrients intake with a meal replacement approach.Methods One hundred and thirty subjects were randomly divided into intervention group (100 subjects) and control group (30 subjects).Besides dietary consulting and health education,all subjects in intervention group received a dietary treatment with 2 meal replacements each day over a shot-term (3 months).All subjects were evaluated by recording the body measurements and laboratory data every 2 weeks.Results Compared with the baseline,mean percentages of BMI loss and decrease in waist circumference were 7.2 ％ and 6.5％ for intervention group(P＜0.01) by week 12.Meanwhile,systolic blood pressure,diastolic blood pressure,fasting plasma glucose,and triglyceride levels were significantly reduced (P＜0.01),showing significant difference compared with control group at the same period(all P＜0.01).Conclusion The meal replacement approach evaluated is an effective strategy to control body weight,and thus to achieve great improvement in the prevention of obesity-related diseases.

[Summary] The efficacy of the combining therapy of methylprednisolone and methotrexate on the Graves ophthalmopathy ( GO) was observed. Whether selenium supplement is beneficial based on this combining therapy scheme was evaluated. The results showed that the combining therapy of methylprednisolone and methotrexate was effective for the patients with moderate-to-severe GO. Selenium supplement did not further improve the remission of GO.

Aim To establish an allogenetic mouse skin trans-plant model,in order to provide a research model for immunosup-pressive drugs. Methods Skins from the ears of C57BL/6 mice were transplanted to the back of BALB/c mice and skin isografts ( BALB/c mice to BALB/c mice) were used as control. Cyclos-porin A( CsA) was used as a model compound to test the imm-nosuppresive effect on allogenetic graft rejection. Following the transplation and CsA treatment, the graft rejection score and graft skin survival rate were quantified. Four and nine days after transplantation,serum IL-4,IL-12 and IFN-γ levels were meas-ured using ELISA kits. Twelve days after transplantation, mice were sacrificed. The weight of spleen and thymus was obtained, and CD4 + and CD8 + population of spleenic T cells were ana-lyzed using flow cytometer. Histological features were assessed by hematoxylin-eosin( HE) staining of formalin-fixed, paraffin-em-bedded graft skins. Results After transplantion, the graft rejec-tion score increased and graft skin survival rate decreased gradu-allly. Serum IL-12 and IFN-γ levels of allograft mice increased markedly. Compared with those of isograft mice, mice with skin allograft displayed a significant increase in the percentage of the CD8 + T cell subpopulation. Remarkable inflammation, such as edema, inflammatory cell infiltration were observed in allograft mice. Compared with saline treated mice, CsA significantly re-duced the graft rejection score and improved survival rate of skin grafts. And also, CsA treated mice had smaller spleen and thy-mus. Mice that received high doses of CsA had significantly less CD8 + T cells than those treated with saline. Moreover, allograft skins in mice that received CsA had less inflammation. Conclu-sions Allogenetic mouse skin transplantation exhibits acute graft rejection. CsA can inhibit the rejection in a dose dependent manner.

OBJECTIVETo explore the anatomic basis and clinical application of the horn shaped perforator flap pedicled with the angular artery for the reconstruction of midface defect.

METHODS(1) 10 fresh cadavers were perfused with a modified guiding oxide gelatin mixture for three-dimensional visualization reconstruction using a 16-slice spiral computed tomography scanner and specialized software (Materiaise' s interactive medical image control system, MIMICS). The origin and distribution of the angular artery perforator were observed. (2) Between July 2012 and July 2014, twenty-one patients underwent operations for the reconstruction of midface defect. Ten patients had squamous cell carcinoma, nine patients had basal cell carcinoma and two patients had nevus. The flaps' size ranged from 1.5 cm x 3.5 cm to 2.5 cm x 5.0 cm.

RESULTSThe facial artery branches the lateral nasal artery 1 cm from the outside corner of the mouth, subsequently strenches to inner canthus continuing as the angular artery. The angular artery anastomoses extensively with the dorsal nasal artery and the infraorbital artery. All the flaps survived. The patients were satisfied with the final aesthetic and functional results.

CONCLUSIONSThe flap can be designed flexibly and simply with reliable blood supply. The donor sites could be closed directly without skin graft, it is a simple and fast method for the reconstruction of midface defect.
