A novel 2-( 2’-hydroxy-5’-chlorophenyl )-6-chloro-4 ( 3 H )-quinazolinone ( ELF-97 )-based fluorescent probe (P1) for hydrogen peroxide was prepared from 5-chlorosalicylaldehyde, 4-(bromomethyl) phenylboronic acid and 2-amino-5-chlorobenzamide, and its structure was characterized by 1 H NMR, 13 C NMR and HRMS. Weak fluorescence intensity was observed at 425nm when the solution of probe P1 was excited by 360 nm UV light. After addition of H2 O2 , however, emission peak at 425 nm disappeared while strong peak emission at 515 nm appeared with the same excitation wavelength ( 360 nm ) . The fluorescence intensity at 515 nm was dependent on the concentration of H2 O2 in the linear response range of 5-45 μmol/L. The detection limit of H2O2 was 0. 1 μmol/L (S/N=3) and the recovery rates of added H2O2 in milk were in the range of 94 . 0%-106 . 0%. Probe P1 was potential to become a useful tool for rapid detection of hydrogen peroxide.

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.

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.

Objective To find the factors lowering the rate of effective thrombus aspiration in patients with STsegment elevation acute myocardial infarction (STEMI) treated with primary percutaneous coronary intervention(PCI). Method From January to December 2008 , a total of 226 AMI patients from Beijing Anzhen Hospital,treated with primary PCI to aspirate the thrombus from the infracted coronary artery via a cannula, were enrolled in a single center retrospective study. The criterion of successful thrombectomy (device success) was defined as the coronary blood flow of involved vessel after PCI resumed to greater than TIMI grade 1. One hundred seventy-eight patients were assigned to effective thrombus aspiration group, and 48 patients without improvement in coronary blood flow of involved vessel after PCI to control group. Data collected after PCI including the normalization of the elevated ST segment,the use of direct stent, ratio of no-flow/slow flow, intra-coronary administration of Tirofiban and the rate of thrombolysis in myocardial infarction (TIMI) flow grade 3 were analyzed with logistic analysis soas to find out the factors affecting the efficacy of thrombus aspiration. Results There were no significant differences in data before PCI between two groups ( P >0.05). Compared with the control group, the factors studied such as smoke, diabetes, the rate of pre-PCI TIMI flow grade 0,the post-PCI ratio of no-reflow/slow flow,and the intra-coronary administration of Tirofiban were fewer significantly in the effective thrombus aspiration group. And the rate of post-PCI TIMI flow grade 3, and the rate of direct stent were higher in the effective thrombus aspiration group. Logistic analysis showed that smoke ( OR = 1.551,95%CI: 1.018 ~ 2. 154, P = 0.012), diabetes ( OR = 1. 132,95%CI:0.276 ~ 3.562, P =0.044), and pre-PCI TIMI flow grade 0 OR = 0.544,95%CI:0.368 ~ 1.911,P = 0.035) were independent factors of effective thrombus aspiration. Conclusions Effective thrombus aspiration may improved the coronary blood flow to TIMI flow grade 3 after PCI and reduce the impaiment of myocardial perfusion, and the factors affecting the efficacy of thrombus aspiration should be paid more attention to and should be minimized to achieve the better clinical outcomes.
