Objective　To evaluation the application value of two-phase enhanced spiral CT in pancreatic adenocarcinoma. Methods　Two-phase enhanced spiral CT was performed in 27 cases of pancreatic adenocarcinoma. After plain CT examination, performed arterial phase（25s after infusion）and portal venous phase（60～70s after infusion）with a 150ml bolus injection of contrast material at 3ml/s. CT attenuation values of tumor and normal pancreas in all scanning phase were obtained and the tumor-pancreas contrast was calculated. Results　Mean tumor enhancement were 48±8 HU（arterial phase）and 72±6 HU（portal venous phase）, normal pancreas enhancement were 125±18 HU、98±11 HU, mean tumor-pancreas contrast was significantly differenced on arterial phase （73±21 HU）and portal venous phase （25±12 HU）. Conclusion　Excellent tumor-pancreas contrast is obtained with arterial phase scans, as such it is of significance reference value for diagnosis pancreatic adenocarcinoma.

BACKGROUND:Skin and soft tissue defects of hands are easy to appear due to different factors, such as trauma. Flap transplantation is a clinical treatment for soft tissue defects of hands. Dorsal foot flap, which is thicker with constant vessel traveling, is very suitable for repair of hand soft tissue defects. OBJECTIVE: To explore the success rate and survival rate of dorsal foot flap transplantation in the repair of hand skin and soft tissue defects. METHODS: A retrospective analysis was performed on the clinical data of 86 patients with skin and soft tissue defect of hands. These patients were respectively given conventional skin wound skin grafting (control group) and dorsal foot flap transplantation (observational group). Hand appearance, infection rate, perception recovery and complications were observed during the postoperative folow-up. RESULTS AND CONCLUSION:Skin flaps al survived after grafting, and the texture of flaps was good. Patients were satisfied with hand shape and the recovery of hand function. After flap transplantation, one patient had local skin necrosis at the donor region, and the scar healed after dressing; another patient had venous crisis, and was given vascular re-anastomosis. In the observation group, the postoperative appearance was better than that of the control group, the infection rate was lower than that of the control group, the perception recovery was better, and there were fewer complications (P < 0.05). These findings suggest that the dorsal foot flap transplantation is better to repair skin and soft tissue defects in the hand.

BACKGROUND:Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder. OBJECTIVE:To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome. METHODS:Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks. RESULTS AND CONCLUSION:Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradualy increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P< 0.05). The results demonstrate that obese mouse models were successfuly constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.

Objective To investigate regional systolic function in left ventricle(LV) and postsystolic shortening(PSS) in patients with essential hypertension with different remodeling patterns of LV by strain and strain rate imaging. Methods According to the level of LV mass index and relative wall thickness, forty patients with hypertension were divided into LV normal geometry(LVN) group and LV remodeling(LVR) group, with thirty healthy subjects as control. The strain and strain rate were compared among the basal,middle and apex segments. Results Compared with control, systolic peak strain and strain rate in both groups of LVN and LVR were decreased significantly(P<0.05). Prevalence of PSS in LVR group (55%) was higher than that in LVN group(39%) and control(22%) with significant differences(P<0.01).Conclusions High prevalence of pathologic PSS in patients with hypertension could implied that unbalance of segmental motion in regional myocardial ischemia. However,presence of PSS in healthy subjects might be the result of synchronization and balance of normal myocardium under physical condition.
