OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.

OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.

METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.

RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.

CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

OBJECTIVETo observe the effect of electroacupuncture (EA) on cytokines in the cardiac surgical patient and to evaluate the application of combined acupuncture anesthesia to cardiac surgery.

METHODSThirty patients with atrial septal defect were divided into 3 groups, general anesthesia group (A), acupuncture anesthesia group (B) and combined general anesthesia and EA group (C). Peripheral blood samples were collected before anesthesia, before cardiopulmonary bypass (CPB), 30 min after CPB and 24 h after operation to determine the levels of interferon-gamma (IFN-gamma), interleukin-2 (IL-2), IL-6 and IL-10.

RESULTSThe levels of IFN-gamma and IL-2 decreased in the 3 groups after CPB and further decreased 24 h after operation, and in the group C were higher than those in the group B. The levels of IL-6 and IL-10 significantly increased 24 h after operation in the 3 groups with no significant difference among the 3 groups.

CONCLUSIONThe general anesthesia combined with EA can not completely improve the decrease of IFN-gamma and IL-2 induced by CPB, indicating that the good response of the general anesthesia combined with EA to stress can partially improve the immunosupression induced by CPB. Acupuncture does not have significant effect on inflammatory cytokine reaction induced by cardiac surgery.

OBJECTIVETo evaluate the correlation of 64-multidetector-row CT (64MDCT) perfusion imaging with microvessel density(MVD) and vascular endothelial growth factor(VEGF) in colorectal carcinoma.

METHODS64MDCT perfusion imaging was performed in 33 patients with pathologically verified colorectal carcinoma. Time-density curves (TDC) were created from the region of interest (ROI) drawn over the tumor, target artery and vein by 64MDCT with perfusion functional software. The individual perfusion maps generated were for blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability-surface area product (PS). MVD and VEGF expression of surgical specimens were examined by immunohistochemical staining with anti-CD34, anti-VEGF monoclonal antibody. MVD and VEGF were compared among the different types of TDC in colorectal carcinoma. The correlation of CT perfusion parameters with MVD and VEGF was also examined.

RESULTSTDC of colorectal carcinoma was divided into five types according to their shapes. MVD in the colorectal carcinoma was 22.61+/-9.01. VEGF staining was found in 25 of 29 tumors (86.2%). The score of VEGF expression was 4.15+/-1.09. No significant differences of MVD and VEGF expression among TDC types were found (F=2.59, 1.11, P>0.05). There were also no correlations of MVD and VEGF expression with any dynamic CT parameters (P>0.05).

CONCLUSION64MDCT perfusion imaging, MVD and VEGF may reflect angiogenic activity, but no significant correlations are found among them.
