Objective To observe the changes of the function of vascular endothelial secretion, levels of OX-LDL and body-weight of obese children after exercise intervention. Methods Thirty children with obesity at the age of 8 to 14 years and 30 normal children were enrolled in this experiment. The obese children (exercise group) received a session of 1 hour's exercise each day, 5 days a week for 8 weeks. The levels of ET, 6-K-PGF1?,NO, OX-LDL and body-weight were then measured and compared with that of their pre-exercise state and that of the normal children (control group). Results The levels of ET and OX-LDL were increased, while the levels of NO and 6-K-PGF1? were decreased in the obese children in comparison with the normal controls, the difference was statistically significant ( P

Objective To explore the ways of repairing the large long-bone and skin defects as single stage procedures. Methods Five clinic cases were studied, firstly, the arteriae fibularis were restructuered into one or two vaso-nasa which nourished the related fibula segments and the overlying skin, then, binding all of the fibula segments and turn it into a bulky bone with a periosteal vaso-nasa wraparound. The graft was rich in blood supply so osteogenesis activity was vigorous under the periostum, the interspace in the graft soon disappear and the graft increased in diameter gradually. Results All of the harvested skin flaps survived and the wound healed on schedule, besides, the involved fractures were union 1 year later and the grafts were strong enough for weight-bearing and walking 2 year later, Neither fracture occur nor morbidity was created at the donor site, No problem was caused at the ankle. Conclusions It's appropriate way to repair large long-bone and skin defects with a vascularized fibula segments complex transfer incorporationg the overlying skin that was supplied via the same peroneal vessel pedicle.

BACKGROUND:The effect of dimethyl sulfoxide cryoprotectants has been got a lot of verification in the low-temperature medical applications. But there is no literature addressing microdialysis detection of dimethyl sulfoxide cryoprotectants. OBJECTIVE:To investigate the microdialysis relative recovery of different concentrations of dimethyl sulfoxide cryoprotectants used for limb reattachment. METHODS:In vitro linear probe relative recovery of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) was detected by retrodialysis gain and loss method. The correction in vivo experiment was done to estimate dimethyl sulfoxide relative recovery in rabbit amputated limbs. RESULTS AND CONCLUSION:The relative recoveries of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) were (49.49±3.56)%, (46.30±1.48)%, (52.66±2.54)%using retrodialysis gain method and (50.99±6.89)%, (43.86±1.35)%, (50.67±0.75)%using retrodialysis loss method. The average recoveries were (49.48±3.18)%and (48.51±4.03)%, respectively. There was no difference in the relative recovery of dimethyl sulfoxide detected using two methods. The change of dimethyl sulfoxide concentration could not influence the retrodialysis gain and loss method calibration results. The recovery was (15.45±4.8)%in vivo. These findings indicate that the microdialysis technology is suitable for dimethyl sulfoxide sampling in vivo that has no obvious influence on the relative recovery.

Objective To determine the capability of emergency physicians (EPs) after goaldirected training to make accurate judgement and assessment of left ventricular systolic function (LVSF) as they own manipulated the hand-held echocardiography.Methods Eighty-one patients with acute dyspneic symptom admitted into emergency department of Xinhua Hospital Affiliated to Shanghai qaotong University School of Medicine from November 2011 to February 2012 were enrolled for a prospective,observational study.Patients with a history of trauma or acute myocardial infarction diagnosed by electrocardiogram were excluded.Four EPs after a intensive course of goal-oriented training in a good command of trans-thoracic echocardiography (TTE) in 81 emergency patients using hand-held echocardiography.EPs attempted to obtain images at the parasternal (long and short axis),apical,and subcostal positions,and visually estimated left ventricular ejection fraction (LVEF) and categorized LVSF as normal function,mild or moderate or severely depressed function.The results of echocardiographic LVEF got by EPs were compared quntitatively with those measured by an professional echocardiographer.The kappa statistical test by using SPSS version 13.0 software was used to allow for comparison in agreement between EPs and the professional echocardiographer's interpretations of TTE findings.Results Using the results of TTE measured by the professional echocardiographer as agold standard,EPs correctly distinguished the normal LVSF from decreased LVSF in 89% patients.The rate of positive predictive value for the EPs identifying any abnormality in LV function was 83% and the rate of negative predictive value was 93%.The kappa coefficient for the agreement between EPs and the professional echocardiographer' s interpretations for any abnormality in LV function was 0.77 (95% CI:0.70-0.84,P < 0.01).EPs correctly placed LV function into one of three categories in 68 of 81 cases (84%),The kappa coefficient for the agreement was 0.71 (95% CI:0.64-0.78,P <0.01).Conclusions Emergency physicians after a intensive course of training in mastering echocardiography can accurately determine the left ventricular systolic function.

Objective To investigate the effects of on-pump and off-pump coronary artery bypass grafting on plasma adrenomedullin (ADM) and endothelin-1 (ET-1) levels before and after operation in elderly patients. Methods Elderly patients aged 60 years and over with coronary artery bypass grafting were enrolled in the study and divided into off-pump group and on-pump group, each group had 20 cases. Blood samples were collected before surgery, immediately after operation and 6,24 hours, 3 days after operation. The plasma levels of ADM and ET-1 were dectecded by radio immunoassay. Results The levels of ADM and ET-1 were significantly increased immediately after operation in 2 groups of on-and off-pump. The levels of ET-1 in on-pump group and off-pump group were (67.59±10.18) ng/L and (58.73±9.64) ng/L respectively. The levels of ADM in on-and off-groups were (284.90±36.24) ng/L and (243.25±25.70) ng/L. This showed that in on-pump group, the plasma levels of ADM and ET-1 increased more significantly(P<0.05). The plasma levels of ADM and ET-1 began to decline at 6 hours after operation, and continued to 24 hours after operation. On 3 days after operation, the plasma levels of ADM and ET-1 in off-pump group returned to the preoperative level, but they were still maintained at a high level in on-pump group.Conclusions For elderly patients, both on-pump and off-pump coronary artery bypass grafting can cause endothelial dysfunction, increasing plasma levels of ET-1 and ADM. But compared with the on-pump coronary artery bypass grafting, the off-pump coronary artery bypass grafting has less influence.
