The effects of sophoramine (SA) on myocardial infarction size and ischemia－induced and reperfusion－induced arrhythmia were studied in conscious rats. It was found that pretreatment with SA 13.3 and 15 mg/kg iv reduced significantly infarct size and cardiac LDH release at 6h afte left descending coronary artery ligation as compared with the control. SA 10.6, 13.3 and 15mg/kg iv decreased markedly the early ischemic arrhythmia in conscious rats. Amiodarone 7.5mg?kg－1 had the same effects on the prevention of ischemic arrhythmia. In reperfusion experiment,it decreased the incidence of ventricalar fibrillation and significantly shortened the duration of arrhythmias. These results suggest that SA has protective effects on myocardial ischemia and reperfusion injury.

Objective To investigate the characteristics and mechanism of W-shaped orthotopic ileal neobladder. Methods A total of 20 patients with W-shaped orthotopic ileal neobladder after total cystectomy were evaluated by urodynamic examinations (questionnaire of urination,uroflowmetry,post-voiding(PVR) residual urine volume measurement,enterocystometry and resting urethral pressure profilometry);meanwhile cystourethrography,B-ultrasound,renal function test and IVU were performed. Results Of the 20 cases,2 suffered from daytime incontinence and 6,nocturnal incontinence.The maximum capacity of neobladder was (492.9?177.8)ml,and maximum pressure within the reservoir was (32.1?8.6 )cm H 2O (1 cm H 2O=0.098 kPa).The urine flow curve showed continual type in 12 cases and intermittent type in 8,with maximum uroflow rates of (14.9?2.5 )ml/s,(7.7?2.8)ml/s;capacity of neobladders of (409.0?96.1)ml,(622.1?197.7)ml;PVR of (9.2?11.8)ml,(69.0?38.4)ml,respectively,in the 2 type groups.These values were significantly different between the 2 groups (P

Objective To realize management of nosocomial consumables in supermarket style by developing bar code input and output modules.Methods Based on No.1 Military Medical Project and Consumables Management System,source codes were extracted and bar code input and output modules were added into original system.Results With the bar code modules,the actual work flow of this system was simplified to be three steps: consumables input by scanning bar codes;scan statistics;consumables output by scanning bar codes.Conclusion A lot of disadvantages in original workflow are removed such as overmuch procedures in workflow,frequent occurrence of errors,high labor repetition,low work efficiency,etc.work efficiency and accuracy are greatly improved and supermarket style management of nosocomial consumables is realized.

Objective To develop a method for the determination of the dynamic parameters of interaction between methotrexate(MTX)enantiomer and dihydrofolate reductase(DHFR).Methods An affinity capillary electrophoresis(ACE)method was adopted.Using bare fused-silica capillary,the electrophoresis buffer was 50 mmoL/L sodium tetraborate with 0.2%Brij-35,pH 9.50.The temperature of separation was controlled at 25℃ and a voltage of 25 kV was applied.The separation of the reaction mixture was performed at a wavelength of 254 nm.The difference of peak areas about the product was used to calculate the inhibitory rate and IC50 values.Results We establish the detection method for the dynamic parameters of interaction between MTX enantioner and DHFR.The separation of the reaction mixture could be achieved within 30 min.The IC50 value of D-(-)-MTX and L-(+)-MTX were 3.17×10-7 and 2.48×10-8mol/L,respective.The IC50 value of the D-(-)-MTX was 31.67×10-8mol/L,the L-(+)-MTX was2.48×10-8mol/L.The IC50 value of the D-(-)-MTX was about 13 times higher than that of the L-(+)-MTX.Conclusions ACE is a rapid.simple and accurate method that can be used to monitor DHFRdynamic reaction.The IC50 values of MTX enantiomer were quite different.The result first indicated that reaction between MTX enantiomer and DHFR had three-dimensional selection.

A 46-year-old female patient presented to our hospital with history of pharyngeal discomfort for 6 months. Physical examination showed that she had facial asymmetry, loss of the left nasolabial fold, rightward de- viation of uvula, swelling of the left soft palate. Magnetic resonance imaging revealed a bigger neoplasm in left pa- rapharyngeal space which invaded into left lateral skull base. The left internal carotid artery, vein and the styloid process was jostled backward. The primary clinical diagnosis is pleomorphic adenoma of the parapharyngeal space.

Objective The purpose of this study was to compare chemerin and CRP levels between women with and without ear‐ly‐onset preeclampsia based on maternal body mass index (BMI) .Methods 45 patients with early onset preeclampsia (gestation week is less than 34 weeks) ,30 normal pregnancy women were enrolled in the study .The serums levels of chemerin and CRP were measured in these pregnancy women .Results The chemerin [(379 .18 ± 52 .09)ng/L ,(481 .27 ± 63 .12)ng/L] and CRP [(7 .59 ± 1 .41)mg/L ,(11 .74 ± 1 .61)mg/L] levels in MPE and SPE were significantly higher than those [(316 .08 ± 51 .90)ng/L ,(3 .47 ± 1 .27)mg/L]in normal pregnancy women(P<0 .05) .While the chemerin(424 .64 ± 46 .61)ng/L and CRP (8 .32 ± 3 .82)mg/L levels increased with maternal BMI in patients overweight and obese women levels compared with normal weight women [(331 .66 ± 51 .77)ng/L ,(5 .93 ± 2 .95)mg/L] ,the difference are significant(P<0 .05) .The correlation analysis showed that the chemerin were positively correlated with BMI ,systolic blood pressure ,diastolic blood pressure ,triglycerides ,and CRP were positively correlated with BMI .Conclusion The expression of chemerin and CRP were associated with severity of preeclampsia and BMI .

Objective To explore the protective effect of vitamin E on the rabbit bladder after partial outlet obstruction artificially setup. Methods A total of 28 New Zealand white male rabbits were divided into 4 groups (group A in 6,group B in 6,group C in 8 and group D in 8).Group A,B and C were fed a regular diet,and group D were placed on a diet enriched with 600 mg vitamin E.After 4 weeks partial outlet obstruction was created in groups C and D,while group B underwent sham operation. After 4 weeks of obstruction each rabbit was sedated and cystometry was repeated.After cystometry the bladder was weighed.The gene expression of sarcoplasmic endoplasmic reticulum,calcium,magnesium,adenosine triphosphatase (SERCA2) in bladder was detected by using RT-PCR assay,while the protein level of SERCA2 was measured by Western blot analysis. Results All parameters measured were approximately identical in nomal rabbits(Group A) and shum operation rabbits(group B).Thus,these 2 groups were combined as the control group(Group A and B).Partial outlet obstruction resulted in bladder weight increased significantly in obstructed groups given vehicle group C(13.07?1.71)g and those vitamin E group D(11.80?2.01)g,4-fold higher than in the control group (2.81?0.30)g(P
