A polyimide coated stir bar for sorptive extraction (SBSE) was prepared by immersion precipitation method, and evaluated by using 5 phenols and chlorinated phenols as model samples. The extraction efficiency of the prepared stir bar was the highest compared with commercial extraction phases of SBSE. Experimental parameters including stir speed, ionic strength, extraction temperature, extraction time, desorption temperature and time were optimized. Under the optimal conditions such as 100 mL of sample, 30 g of NaCl, extraction time of 30 min, stirring speed of 800 r/ min and at 25℃, the target compounds were recovered by thermal desorption at 300℃ for 4 min, more than two orders of magnitude of linearity was obtained (R≥0. 9995), LOQs (S/ N=10) were 0. 028-0. 123 μg/ L, and RSDs were in the range of 1. 6% -9. 7% . The polyimide SBSE coupled with gas chromatography-mass spectrometry was applied to the extraction/ enrichment and analysis of phenols in real samples, including tap water, sea water, and waste water. It was found that the polyimide SBSE showed high selectivity towards polar compounds and high thermostability up to 350℃.

Objective To investigate the protective effects of Bauhinia championii Benth flavones(BCF) on oxidative stress of neonatal rat cadiocytes induced by H2O2.Methods Cadiocytes of neonate rat was cultivated for 72 hours and divided into six groups: a normal control group, a H2O2 group, BCF(60, 120 and 240μg/ml)+H2O2 groups and aShuxueninginjection (100μg/ml)+H2O2 group (n=8). 6 hours after the drugs were given, the morphology changes was observed and the survival rate was detected; the content of AST, CPK, LDH in culture medium were detected; the activity of SOD, CAT, GSH-Px and the content of MDA in cardiomyocytes were also determinted; the apoptosis rate were detected, and the expression of caspase-3 in cardiomyocytes was detected by Western blot.Results Compared with the H2O2 group, the activity of AST(28.8 ± 6.1 U/ml, 24.5 ± 5.3 U/mlvs. 36.2 ± 6.7 U/ml), CPK(1.8 ± 0.4 U/ml, 1.5 ± 0.3 U/mlvs. 2.5 ±0.4 U/ml), LDH(805.2 ± 160.9 U/L, 671.5 ± 128.7 U/Lvs. 916.5 ± 168.4 U/L) in culture medium were significantly decreased (P<0.05,P<0.01), the activity of SOD(84.8 ± 17.4 U/mg, 95.3 ± 18.2 U/mgvs. 55.7 ± 13.1 U/mg), CAT(23.4 ± 3.1 U/mg, 26.3 ± 3.5U/mgvs. 15.2 ± 3.0 U/mg) in cardiomyocytes were significantly increased and the content of MDA(8.1 ± 1.7 nmol/mg, 6.8 ± 1.5 nmol/mgvs. 11.1 ± 2.3 nmol/mg) were significantly decreased (P<0.05,P<0.01), the expression of c caspase-3(1.64 ± 0.16, 1.30 ± 0.12vs. 2.06 ± 0.25) and the apoptosis rate (24.2% ± 5.5%, 13.4% ± 3.9%vs. 51.2% ± 9.1%) were significantly decreased (P<0.05,P<0.01); the activity of GSH-Px (3.6 ± 0.9 U/mg vs. 2.4 ± 0.7 U/mg) in cardiomyocytes of BCF 240μg/ml treatment group was increased (P<0.05).Conclusions BCF could effectively improve the morphology of neonatal rat cadiocytes induced by H2O2, increase the survival rate, improve the activity of antioxidase, down-regulate the expression of caspase-3 and decrease the apoptosis rate, suggesting that BCF had dose-dependent protective effects on oxidative stress of neonatal rat cadiocytes induced by H2O2.

Objective We aimed to assess effectiveness of Risk Score Scale (RSS) for aortic Dissection (AD) in early triage stage.Methods A total of 251 patients with acute chest or back pain complaints were allocated by triage nurses according to the pre-established RSS from 2011 to 2013.87 cases were assessed to have 5 points or more,and 80 cases were assessed to have 6 points or more from 95 patients diagnosed as aortic dissection (the diagnosed group) by CT angiography and magnetic resonance imaging while excluded 156 cases of control after discharge (control group).The general conditions,distribution of aortic dissection risk factors,aortic dissection risk score,sensitivity and specificity of RSS between two groups were compared.The misdiagnosis rate,missed diagnosis rate,RSS triage sensitivity and specificity and OR value were compared between RSS ≥5 points and RSS ≥6 points.Results There was significant differences in abrupt onset of severe pain intensity,ripping or tearing pain,pulse deficit or systolic blood pressure differential between extremities [upper extremity≥20 mmHg (1 mmHg=0.133 kPa) or lower extremity≥ 10 mmHg],x2 value was 62.6,94.2 and 20.2.RSS≥5 points had high sensitivity and specificity,lower missed diagnosis rate and high OR value for triage application.Conclusion RSS≥5 points could serve as a reliable evidence for early triage of aortic dissection.

Objective To detect the new views for pulmonary vascular by transesophageal echocardiography(TEE) during lung transplantation.Methods Seventeen cases with respiratory failure underwent lung transplantation.A series of scans were detected by TEE during preoperative anesthesia, preand pro-pulmonary vascular occlusion and pro-donor lung, and bronchus, pulmonary veins, pulmonary artery anastomoses.Left and right lung veins open and left and right pulmonary artery branch were key to observed.Pulmonary artery trunk and branch diameter, velocity of blood flow were measured.Results All left and right pulmonary artery,pulmonary vein images were given by TEE.TEE detected the normal blood flow velocity of pulmonary artery branches during pre-operation,average of 65 cm/s.After clipping the side of the pulmonary artery, the lateral pulmonary blood flow disappeared.TEE detected pulmonary veins,pulmonary artery anastomoses pro-operation.Except for 1 case of anastomotic pulmonary vein flow velocity increased,all the pulmonary vein and pulmonary artery branch anastomoses flow velocity increased slightly faster than those before transplantation (mean pulmonary artery branch of 160 cm/s, the average pulmonary vein 149 cm/s).Conclusions TEE can monitor diameter and flow velocity of pulmonary artery branch and pulmonary vein during lung transplantation,and can detect the rightventricular function.The views of left and right branch pulmonary artery and pulmonary vein branches play an important role during lung transplantation.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

Objective To evaluate right ventricular function of chronic thromboembolic pulmonary hypertension (CTEPH) patients by echocardiography and cardiac magnetic resonance (CMR),and to evaluate the value of clinical application of those right heart function indexes.Methods 32 patients with CTEPH who underwent CMR and echocardiography were involved in the study.Right ventricular index of myocardial performance (RIMP),fractional area change (FAC),tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler-derived tricuspid lateral annular systolic velocity (S') were measured by echocardiography.Right ventricular end-diastolic volume (RVEDV) and end-systolic volume (RVESV) were measured by cardiac magnetic resonance and right ventricular ejection fraction (RVEF) was calculated.Results A positive correlation was found between FAC and RVEF (r =0.423,P =0.022),there was a negative correlation between RIMP and RVEF (r =-0.387,P =0.048),there was no correlation between TAPSE and RVEF (r =0.451,P =0.22),a positive correlation was found between S' and RVEF (r =0.689,P =0.000).Conclusions The echocardiographic parameters FAC,RIMP and S' can reflect right ventricular function in patients with CTEPH and can be used as a routine clinical parameters.

Objective To assess the usefulness of left ventricular contrast echocardiography in diagnosis of left ventricular myocardium noncompaction.Methods Contrast echocardiography was done in ten patients who were diagnosed or suspected with left ventricular noncompaction by common transthoracic echocardiography,for further study of the trabecular muscles extent,the continuity of the endocardium,the compact myocardium thickness,and the contrast agent in the trabecula recessus.Results By contrast echocardiography,noncompaction myocardium thickness can be perspicuously observed,the turgor of the contrast agent was vividly detected in the trabecular recessus.Especially for the measurement of compaction myocardium,the contrast echocardiography was more accurate than in the condition of the common echocardiography.Conclusions Left ventricular contrast echocardiography can be used in the diagnosis of left ventricular noncompaction,it was a good added method of conventional echocardiography.
