Objective To investigate the utility of urodynamic testing in the evaluation of neurogenic vesicoureteral reflux in patients with thoracolumbar spinal cord injury at the T10 to L2 level.Methods Twenty-six patients with thoracolumbar spinal cord injury at the T10 to L2 level and who displayed vesicoureteral reflux were enrolled and divided into a detrusor hyper-reflexia group (n =21) and a detrusor a-reflexia group (n =5)according to their cystourethrograms and urodynamic test results.Their bladder volume,detrusor pressure (Pdet) and compliance were observed and analyzed at the vesicoureteral reflux point and the leak point.Results The bladder volume and compliance of the detrusor hyper-reflexia group at the vesicoureteral reflux point were (122.46 ± 87.89) ml and (5.94 ± 4.96) ml/H2 O respectively,significantly different from the detrusor a-reflexia group (P ＜ 0.01).At the leak point,the average bladder volume of the detrusor hyper-reflexia group was (210.81 ± 69.72)ml,while the average bladder compliance was (9.53 ± 5.43)ml/H2O and the average detrusor pressure was (42.29 ± 9.57)cm H2O.All were significantly different from the detrusor a-reflexia group's averages.Moreover,there was a significant difference in the Pdet between the leak point and the vesicoureteral reflux points in the detrusor hyper-reflexia group.Conclusions Patients with thoracolumbar spinal cord injuries at the T10 to L2 level with neurogenic bladder and detrusor hyper-reflexia have low bladder volumes and compliance,and vesicoureteral reflux tends to occur at an early stage after injury with a destrusor pressure lower than 40 cm H2 O.For patients with detrusor a-reflexia,vesicoureteral reflux and bladder leakage may occur when detrusor pressure is low.

Objective To compare the hemostatic efficacies of radial artery balloon and spinning hemostat in elderly patients after radial artery intervention.Methods Eighty elderly patients undergoing transradial coronary intervention were randomly divided into balloon and spinning hemostat groups,with 40 cases in each group.After operation,balloons and spinning hemostats were used for hemostasis,respectively.The two groups were compared in terms of hemostatic effect,comfort degree and incidence of complications.Results These was no difference in hemostatic effect between the two groups(P>0.05).The balloon hemostat group was better than the spinning hemostat in respect of comfort degree.The incidences of ischemia and vagal reflex in the balloon hemostat group were significantly lower than the spinning hemostat group(P<0.05).Conclusion The balloon hemostat for radial artery intervention is more suitable for elderly patients undergoing oral treatment.

Objective To study the relationship between general self-efficacy, social support, psychological health and working efficiency.Methods Using General Self-efficacy Scale (GSES), Social Support Rating Scale, Symptom Checklist-90 (SCL-90) and supervisor's rating of work efficiency to investigate 262 nurses. And using correlation and regression analyze the results. Results Correlation analysis found that general self-efficacy and subjective social support had significant negative correlations with the general symptomatic index of SCL-90( r =-0.31,-0.29,P <0.05).Results of regression analysis showed that general self-efficacy, objective social support, using of the social support, and general symptomatic index of SCL-90 had significant effects on working efficiency (β=0.41,0.36,0.35,-0.28,P <0.05).Conclusion Working efficiency of nurses is mainly effected by general self-efficacy, objective social support, using of the social support and psychological status. As a result,all these factors should be taken under consideration in order to improve working efficiencies of nurses.

Objective To explore species specificity of 29 Y-SNP loci and to lay the foundation for forensic application.Methods Human DNA and 8 different kinds of common animals' DNA were amplified separately by PCR.The PCR products were analyzed with PAGE.Results Twenty-three out of 29 Y-SNP loci were only amplified by the male human DNA,which indicated a good species specificity.Three loci amplified from human and some animals showed that the length of the product was different between two species.Another three loci amplified from human and animal showed that the length of the fragment was similar between human and animal.Five loci were amplified by PCR products from both male and female samples.Conclusion Most of 29 Y-SNP loci,amplified in male humans,have good species specificity and can be directly used for personal identification and paternity testing.

Objective:To find out markers of endometriosis. Methods: The two dimensional gel images of proteins extracted from eutopic endometrium from endometriosis patients and controls were analyzed by software Phoretix 2D,and the proteins expressed differently were identified primarily by query of data base.The proteins extracted from ectopic endometrium of ovarian endometriosis were transferred from two dimensional gel onto nitrocellulose membranes,followed by incubation with sera from women with and without endometriosis. Analyzed by MALDI-TOF-MS,the proteins hybridized differently were identified through their Peptide Mass Footprints. Results: Having compared the reproducible two dimensional gel images of proteins from eutopic endometrium of women with and without endometriosis,we obtained 11 proteins expressed differently.Through Western Blot technique,we found three proteins hybridized differently which were identified as vimentin,?-actin and ATP synthase ? subunit respectively. Conclusion: The protein expression spectra of eutopic endometrium from patients with endometriosis are significantly different from those of the controls,and the anti-endometrial autoantibodies against vimentin, ?-actin and ATP synthase ? subunit may be induced.

Objective To investigate the value of prenatal ultrasound in diagnosis and treatment of twin reverse arterial perfusion (TRAP) syndrome. Methods A retrospective study was performed in 5 TRAP cases, including ultrasound images, clinical data and pregnancy outcomes. The sonographic characteristics were summarized. Results Five TRAP cases were diagnosed during 13 to 28 weeks' gestation and confirmed after birth. Color Doppler unltrasonography revealed retrograde umbilical artery perfusion towards acardiac twin. Two of 5 cases ended up in induced abortion, 1 in spontaneous abortion, 1 was delivered at 37 weeks' gestation after ultrasound-guided feticide of the acardiac twin and 1 was monitored closely with ultrasound and delivered alive at 32~(+4) weeks' gestation. Conclusion Prenatal ultrasonography has great applicative value for TRAP syndrome in early diagnosis, choosing optimal treatment and prognosis assessment.

Aim To explore the effect of adenylate cyclase(AC) antagonists SQ22536 and agonist forskolin on acute lung injury induced by lipopolysaccharide.Methods ICR mice were randomly divided into normal saline control group(N group), model group(group L), dexamethasone group(group D),AC antagonists s(group SQ) and AC agonist group(group F).The ALI mouse model was induced by instilling intratracheally with LPS(2 mg·kg-1), and 6 h later, the lung tissue and alveolar lavage fluid(BALF) were harvested, pathological changes in lung were observed, white blood cell and neutrophil, albumin content in BALF and myeloperoxidase(MPO) activity of lung tissue homogenate were determined, and tumor necrosis factor α(TNF-α), interleukin-1β(IL-1β), interleukin 6(IL-6) and cAMP content in lung homogenates were detected by ELISA.Results Compared with normal saline group, a large number of neutrophils infiltrated around the pulmonary vessel and airway 6 h after LPS intratracheal instillation in model group.White blood cells and neutrophils and protein content increased in BALF;MPO activity and cAMP levels increased in lung tissues.In the lung tissue TNF-α and IL-6, IL-1β content increased, compared with model group.Forskolin could improve the pathological changes of lung tissue, reduce the total number of leukocytes, number of neutrophils and protein content in BALF, and reduce MPO activity and TNF-α content in lung tissue, at the same time it increased the cAMP content;SQ22536 had no significant effect when compared with model group.Conclusion AC agonists have protective effects on LPS-induced acute lung injury in mice, and the mechanism may be related to elevating cAMP levels, inhibiting neutrophil adhesion and chemotaxis and reducing inflammatory factor levels.
