Objective To explore the significance and correlation between MCP-1 and cardiovascular complication of diabetes. Methods 65 patients with diabetes and 64 patents with IGT and 60 healthy persons as control group are chosen from a population of 1231residents at Jiangnan community in Guangzhou city. Ultrasonic inspection of carotid artery was applied to the intimae media thickness (IMT),and the levels of-MCP-1 were detected by Elisa. Result There was significant difference in the levels of MCP-1 among the normal control group, IGT group and DM group (P=0.000).The levels of MCP-1 in IGT complicated with AS patients were significantly higher than that in IGT alone patients. The levels of MCP-1 in DM complicated with AS patients were significantly higher than that in DM alone patients. The levels of MCP-1 were positively correlated with IMT in these patients. A forward LR Logistic regression analysis showed that IMT was a dependent variable, gender, MCP-1 and age are independently correlated with IMT. Conclusion MCP-1 is correlated with diabetes and its cardiovascular complication and it may be served as the target of therapy.

OBJECTIVETo investigate the technique and therapeutic effect for correction of sunken eyes combined with ptosis.

METHODSIn order to adjust the levator muscle tension and the relationship between levator aponeurosis and tarsus plate, multiple individualized treatment was selected, including levator aponeurosis restoration, levator aponeurosis plication, or shorten, or combination. Then the orbital fat was transferred to the depressed area, or autologous fat particles were collected and injected into the depressed area within the orbital fat fascia. After the orbital septum fascia was restored, the incision was closed primarily.

RESULTS15 cases (30 eyes) were treated. 11 cases were followed up for 6-40 months (average, 9.5 months) with satisfactory cosmetic and functional result. No recurrence of ptosis happened.

CONCLUSIONSOne-stage correction of sunken eyes combined with ptosis can be achieved with autologous fat injection or orbital fat transposition. Good cosmetic and functional result can be achieved.

Objective To establish the three-dimensional model of pancreas and its surrounding structures.Methods The three-dimensional pancreas model was established and analyzed by using PC computer platform based on the data set from the first Chinese visible human female.Results The three-dimensional pancreas model,established successfully,could be rotated at any angles and could be sectioned at any orientation.The structures of each section could be displayed clearly.Conclusion Sectional anatomy at any orientation of the pancreas and its surrounding structures can be performed on our pancreas model,which has laid the foundation for virtual surgery of the pancreas.

OBJECTIVETo investigate the effectiveness of microbubble-enhanced ultrasound (MEUS) for detecting perforators preoperatively in supraclavicular flap surgery.

METHODSFrom May 2009 to October 2013, there were 20 patients (26 flaps were involved) who planned to undergo supraclavicular artery based flap surgeries to recover the large-area defects in head and neck. The MEUS together with regular color Doppler ultrasound ( CDUS) were conducted preoperatively to determine the anatomical features of perforators branching from supraclavicular arteries (SCA). The perforator with wider caliber, faster flow speed, longer pedicles and closer pivot point was selected and the flap was designed according to the observed results.

RESULTSThere were 37 perforators of SCA detected by CDUS, whose calibers were ranging from 0.5 to 0.8 mm [Mean: (0.6 ± 0.1) mm]. There were 48 perforators of SCA detected by MEUS. Compared to CDUS, the caliber obtained from MEUS for same vessel is significantly increased [(0.7 ± 0.3) mm vs (0.6 ± 0.1) mm, P < 0.05]. According to the results of MEUS and three-dimensional reconstructive techniques, in at least 65.4% (17/26) of the flaps, thoracic branch of SCA (TBSA) has large caliber and good flow velocity which can be regarded as the predominant vessel and used as the pedicle of flap. The results of the operations confirmed the existences of all the marked vessels. 25 flaps were obtained according to the preoperative plans and one case used perforators of internal mammary artery as free flaps since the perforator of SCA was found improper. The contrast-related complication occurred in one patient which was manifested by gastrointestinal adverse effect like nausea and anorexia. The patient recovered 1 day later without treatment. All the patients have been followed up for 3 to 16 months (Mean: 8 months) with well-survived flaps.

CONCLUSIONSThe perforators of SCA demonstrated significant variations and preoperative mapping was vital for the success of surgery. MEUS is a valuable imaging modality for the preoperative assessment of the vascular supply for supraclavicular artery based flap.

Objective To explore the mechanism of anti-tumor effects of transferring tumor-specif-ic lymphocytes obtained from pre-immunized BALB/c mice with inactive rolL-21 tumor vaccine (mIL-21-Sp2/0)to syngeneic mice, associated with mIL-21 tumor vaccine immunization, in the condition of cyclo-phosphamide (Cy)-induced lymphopenia. Methods Activated lymphocytes of spleen and lymph nodes ob-tained from pre-immunlzed syngeneic mice with irradiated mIL-21-Sp2/0 cells were infused into BALB/cmice treated with Cy 2 days before, subsequently vaccinated with mlL-21 tumor vaccine, after 7 days, chal-lenged with Sp2/0 tumor cells, observed the growth of tumor of mice. T lymphocyte subsets differentiation was measured by flow cytometry (FCM) analysis. The proliferation and cytotoxie activities of activated lym-phocytes were analyzed by FCM, respectively, staining with CFSE and 7-AAD. The number of IFN-γ-secre-ting cells was evaluated by ELISPOT. Results The lymphopenic mice were transferred with activated lym-phocytes and inoculated with raiL-21 tumor vaccine might provide superior anti-tumor immunoprotection, re-tard tumor growth of the mice. The proliferating capabilities and killing rate of transferred tumor Ag-specific lymphocytes enhanced obviously, the number of IFN-γ-secreting cells was significantly higher compared with the control groups. Conclusion Under Cy-induced lymphopenia condition, tumor Ag-specific lymphocytes sensitized by raiL-21 tumor vaccine were transferred to mice and immunized with mlL-21 tumor vaccine at the same time, benefit the proliferation of transferred effective cells and immune cells itself, assist to form and sustain special anti-tumor effects.

AIM: To explore the significance of platelet activation, fibrinolytic activity and the changes of vasoactive mediators in acute myocardial infarction in rabbits and the intervention of amiodarone and metoprolol. METHODS: Fifty New Zealand white rabbits were randomly assigned to five groups, ten for each. Group Ⅰ: sham group, group Ⅱ: acute myocardial infarction(AMI) group, group Ⅲ: AMI and lidocaine group, group Ⅳ: AMI and amiodarone group, group Ⅴ: AMI and metoprolol group.The middle point of left ventricular coronary artery was ligated (groupⅡ,Ⅲ, Ⅳ and Ⅴ ) or a sham ligation(group Ⅰ). Four hours later, blood was collected for measuring plasma concentration of TXB 2, 6-Keto-PGF 1?, ET, NO, plasma activity of t-Pa and PAI.After that, the heart was taken out to evaluate the infarction size(IS). RESULTS: Plasma concentration of TXB 2, ET, NO and plasma activity of PAI were significantly higher in groupⅡ,Ⅲ, Ⅳ and Ⅴ than those in group Ⅰ(P0.05).Compared to group Ⅱ, plasma concentration of ET, NO and PAI activity were significantly decresed (P
