A sensitive high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) method was established for the determination of eplerenone (EP) in human plasma. The plasma samples of EP were extracted with ethyl acetate and separated by HPLC on a reversed phase C18 column with a mobile phase of 10 mmol x L(-1) ammonium acetate water solution-methanol (30 : 70, v/v). EP was determined with electrospray ionization-mass spectrometry (ESI-MS) in the selected ion monitoring (SIM) mode. The calibration curves were linear over the range of 2-4 000 ng x mL(-1) for EP. The lower limit of quantification was 2 ng x mL(-1). The method has been successfully applied in the pharmacokinetic study of the EP tablets. The main pharmacokinetic parameters of EP after oral administration of 25 mg, 50 mg, 100 mg were as follows, t1/2: (4.9 +/- 2.1), (4.7 +/- 1.5), (5.9 +/- 1.2) h; AUC(0-infinity): (4 402 +/- 1 735), (8 150 +/- 2 509), (13 783 +/- 4 102) microg x h x L(-1); and MRT: (6.2 +/- 2.1), (6.6 +/- 1.3), and (7.2 +/- 1.6) h. Parameters of EP after oral administration of multiple doses of 50 mg were as follows, t1/2: (6.1 +/- 1.7) h; AUC(ss): (10 071 +/- 4220) microg x h x L(-1); MRT: (8.1 +/- 2.3) h; and DF: (3.2 +/- 1.0).

Methods 290 nursing students with different educational systems were selected, then interviewed for the coping styles and general states by questionnaires. And the datum were analyzed with the SPSS 13.0. Results The score of active coping was (42.00±20.57), and the score of negative coping was (34.00±13.24) in 290 nurses. Among the different demographic characteristics, sex, educational system, origin, whether or not only child and culture degree of parents had inlfuece to active coping, and there were significant differences for the coping styles (P<0.05). Conclusions In order to cultivate the favorable coping style, the psychic-training and the consulation should be done uninterrupted, the lecture of mental health education and the the coping style training should be given regularly for the different students.

To explore the present status of fluid therapy and clinical outcome in critically ill patients in intensive care units (ICU).ICU patients consecutively admitted to our ICU were prospectively enrolled.Patients' demographics,laboratory data,fluid record and clinical outcome were collected.Fluid intake quantity of all patients was at peak on the fifth day which was 2 806 (1 997,3 582)ml.From the fourth day in ICU,fluid balance started to benegative as-84 (-1 127,612)ml and gradually increased.Crystalloid solution was the main components.For treatment purposes,medication injections and nutrients were major fluids.Positive correlations were found between total fluid intake quantity,total crystalloid volume,total colloidal volume and hospital stay,ICU stay,duration of intubation (r values as 0.211,0.686,0.282,0.155,0.506,0.174,0.209,0.072,0.292,respectively P＜0.05).Moreover,positive correlations were also demonstrated between total colloidal volume and total bilirubin,direct bilirubin,alanine transaminase,aspartate transaminase,blood urea nitrogen,serum creatinine (r values as 0.196,0.242,0.190,0.335,0.284,0.223,respectively P＜0.05).

Objective To study the dosimetry of different arrangements of 125I seeds in one plane.Methods Nine different in-plane arrangements of 9 125I seeds (2.035 × 107 Bq/seed) were simulated according to distance (cm) along x (horizontal)- and y( longitudinal )-axis using the 3-dimensional treatment planning system (TPS) (3D-TPS): x0.5, y0. 5; x0. 5, y1.0; x0. 5, y1.5; x1.0, y1.0; x1.0, y1.5;x1.5, y1.5; x0. 5, y0. 5 (2)1.0; x0.5, y1.0 (2)0.5; x1.0, y1.0 (2)0.5. The isodose curves of 40,80, 130, 145 and 200 Gy were created and the area, radius and medical cost under the 40, 80, 130, 145and 200 Gy isodose curves were calculated. Results The area, radius and medical cost under the same isodose curves were significantly different with each 125I seed arrangement. The arrangements which had the biggest area under curves of 40, 80, 130, 145 and 200 Gy isodose were x1. 5, y1. 5; x1. 0, y1. 0; x1. 0,y1. 0; x0. 5, y1. 0 and x0. 5, y1. 0, respectively. Conclusion The matched peripheral dose and therapeutic effect were affected significantly by the geometric arrangement of 125I seeds.

This study was aimed to detect the ratio of CD34+ cells in bone marrow mononuclear cells (BMMNCs) and the expression rate of G(M)-CSFR on CD34+ cells in bone marrow of the patients with aplastic anemia (AA) and myelodysplastic syndrome (MDS). The ratio of CD34+ cells in BMMNCs and the expression rate of G(M)-CSFR on cells of 27 AA patients, 45 MDS patients and 20 controls were detected by flow cytometry (FCM). The results showed that the ratio of CD34+ cells in BMMNCs of AA patients reduced and was significantly different from controls (p<0.05), the ratio of CD34+ cells in MDS patients elevated and was significantly different from controls (p<0.05). Compared with controls and MDS-RA patients, the ratio of CD34+ cells in MDS-RAEB patients significantly elevated (p<0.05), but there was no significant difference between MDS-RA patients and controls (p>0.05). The ratio of CD34+ cells in MDS-RA patients was significantly higher than that in AA patients (p<0.05). There was no significant difference in expression rate of G-CSFR on CD34+ cells between AA patients and controls, MDS patients and controls, AA patients and MDS patients, MDS-RA patients and MDS-RAEB patients (p>0.05). The expression rate of GM-CSFR in MDS patients was significantly higher than that in AA patients and controls (p<0.05), but there was no significant difference between AA patients and controls, MDS-RA patients and MDS-RAEB patients (p>0.05). In AA patients, the ratio of CD34+ cells in BMMNCs was less than 0.1% accounts for 6/8 SAA patients, compared with 2/19 in CAA (p<0.05). There was no correlation between the expression rate of either G-CSFR or GM-CSFR and neutrophil count at diagnosis (r=0.058 and r=0.044). In MDS patients, there was no correlation between bone marrow CD34+ cells ratio and peripheral neutrophil count at diagnosis (r=-0.335). And there was no correlation between the expression of either G-CSFR or GM-CSFR and neutrophil count on diagnosis (r=0.064 and r=0.051). It is concluded the detection of CD34+ cells and their surface expression rate of G(M)-CSFR in AA and MDS is useful in diagnosis and differential diagnosis of these two diseases.

OBJECTIVETo summarize experience of perioperative anesthetic management for patients undergone excision of pheochromocytoma and complicated with catecholamine cardiomyopathy.

METHODSPerioperative anesthetic management for surgical treatment of three cases of pheochromocytoma complicated with catecholamine cardiomyopathy was described and discussed according to literature reports.

RESULTSThe catecholamine cardiomyopathy of the three cases presented with left ventricular hypertrophy, congestive cardiac failure and acute myocardial infarction. After removal of the pheochromocytoma under general anesthesia, a prolonged hypotension occurred in all of the three cases. In order to maintain stable hemodynamics, large dose of catecholamine was required after surgery. All of the three patients were survived and discharged.

CONCLUSIONSIt is suggested that myocardial dysfunction may be another important factor for the prolonged hypotension after removal of the tumor. Meticulous preoperative assessment of heart function is of primary importance for the management of anaesthesia during surgical procedures.
