Objective:To observe any effect of repeated magnetic stimulation of the spine on lower urinary tract function and the life quality of patients with neurogenic bladder after suprasacral spinal cord injury (SCI).Methods:Fifteen suprasacral SCI patients whose lower urinary tract function was not improving were enrolled. In the first 2 weeks, all received water drinking management and intermittent catheterization, while in the following 4 weeks they were additionally provided with daily transspinal magnetic stimulation at the level of the spinous process of the first lumbar vertebra five times a week. The stimulation frequency was 1Hz. The patients kept voiding diaries. Their urodynamics were quantified using neurogenic bladder symptom scoring (NBSS) and a life quality scale.Results:The frequency of catheterization and the average voided volume, as well as the maximum detrusor pressure during the storage phase, maximum bladder capacity, maximum urethral pressure during the voiding phase and voiding efficiency at the end of the sixth week were significantly different from those at the end of the second week and before the intervention. The average NBSS and life quality scores then showed significant differences from the earlier time points.Conclusion:Repeteitive transspinal magnetic stimulation of the spine can improve lower urinary tract functioning and the life quality of persons with neurogenic bladder after a suprasacral SCI.

Objective: To analyze the predictors of left ventricular reverse remodeling in patients with III? atrio-ventricular block (AVB) combining left ventricular systolic dysfunction after cardiac re-synchronization therapy (CRT). Methods: A total of 65 III? AVB patients received CRT in our hospital from 2009-01 to 2015-05 were enrolled. Clinical information before and after the operation were recorded. Left ventricular reverse remodeling was deifned by left ventricular end systolic volume (LVESV) decreased 15% or left ventricular ejection fraction (LVEF) increased≥5% at 12 months after CRT. The patients were divided into 2 groups: Reversal group,n=36 and No reversal group,n=29. Clinical condition was compared between 2 groups, predictors for CRT reversing left ventricular remodeling were evaluated by two classiifcation Logistic regression analysis. Results: The patients' average age was (62±14) years and 36/65 (55.4%) with reverse remodeling. In Reversal group, the ratios of female (P=0.011), baseline QRS width>120ms (P=0.001), inter-ventricular mechanical delay (IVMD)≥40 ms (P=0.027) and standard deviation of time-to-minimum systolic volume of 16 segments [Tmsv16-SD (%R-R)≥8.3%, (P=0.001)] were higher than those in No reversal group. Two classiifcation Logisitic regression analysis indicated that female (OR=6.228, 95%CI 1.561-24.842, P=0.01), QRS duration>120 ms (OR=7.778, 95% CI 1.996-30.769,P=0.003) and Tmsv16-SD (%R-R)≥8.3% (OR=8.134, 95% CI 2.064-32.057,P=0.003) were the independent predictors for ventricular reverse remodeling . Conclusion: Female, QRS>120ms and Tmsv16-SD (%R-R)≥8.3% could be used as the predictors for CRT reversing left ventricular remodeling in III? AVB patients combining left ventricular systolic dysfunction.

Résumé
BACKGROUND:Procolagen type 1 N-terminal propeptide (P1NP) and β-colagen special sequence(β-CrossLaps) are two bone metabolic markers that are closely related to osteoporosis. Combined detection of bone metabolic markers and bone mineral density is of clinical significance for the diagnosis of osteoporosis. Bone metabolic markers are ideal indicators to predict fractures, which can compensate for the lack of bone density test. OBJECTIVE:To introduce the application of bone metabolic markers in the monitoring of drug efficacy on the treatment of osteoporosis as wel as in the prediction of fracture risks in recent 20 years and to explore the clinical values of P1NP and β-CrossLaps to assess the therapeutic efficacy on osteoporosis and risks for osteoporotic fractures. METHODS:A computer-based search of CNKI and SCI databases were performed for relevant articles published from 2000 to 2014 using the keywords of “serum bone metabolic markers; osteoporosis; bone mineral density” in Chinese and English, respectively. Finaly, 44 articles meeting the inclusive criteria were reviewed. RESULTS AND CONCLUSION:This paper analyzes the source and detection mechanisms of P1NPand β-CrossLaps and then compares their advantages in the therapeutic effect assessment of osteoporosis. Serum bone metabolic markers cannot only reflect the dynamic changes of bone metabolism, but also have earlier changes than the bone mineral density. Both P1NPand β-CrossLaps are very important for assessing the early diagnosis of osteoporosis as wel as anti-osteoporosis drug efficacy.

Objective To assess visibility of scleral spur in images of anterior chamber angle measured by the CAM model of Fourier optic coherence tomography (OCT). Methods Subjects aged 40 years or older were selected from outpatients in our opthalmologic clinic. All participants underwent standard ocular examinations, and anterior chamber angle was measured by CAM-L model of RTVue-OCT (Optovue Inc,USA) and gonioscopy. Visibility of scleral spur in OCT images and its related factor were analyzed. Results 98 subjects (98 eyes) aged (63.3±10.5)y included 62 females (63.3%) were selected in this study. There were 286 in 392 quadrants (73.0%) with visualized scleral spur, which had significant difference among local bulbar conjunctiva thickened or not (P<0.01). Logistic multiple regression showed that the visibility of scleral spur was not associated with gender, age, gonioscope grades (P>0.05), but significant associated with local bulbar conjunctiva thickened (OR=0.113, P<0.01) and quadrants (OR of superior/temporal=0.210, OR of inferior/temporal=0.340, P<0.01), of which there were different scleral spur visibility in superior and inferior quadrants compared with temporal(OR=0.210, 0.340, P<0.01). Angle status was still identified in 80.2% quadrants on condition that scleral spur was not visualized. Conclusions Fourier optic coherence tomography has good feasibility to detect anterior chamber angle as an alternative method, and may supply helpful information to estimate the pathogenesis of angle closure glaucoma.

Objective To explore diagnosis capability of macular ganglion cell complex (mGCC)and peripapillary retinal nerve fiber layer(pRNFL) thickness for glancoma. Methods Adult outpatients received ocular regular examinations of glaucoma in our hospital were enrolled in this study. Parameters of pRNFL and mGCC measured by Fourier optic coherence tomography(OCT) were evaluated. Results 116 subjects ( 116 eyes) included 51 (44. 0% ) normal subjects, 30(30. 2% ) early glaucoma patients and 35 (25.9%) advanced glaucoma patients. There were significantly different pRNFL and mGCC thickness among the three groups ( F = 83.022,97. 361,27. 899,79. 585,140. 686,119. 166,116. 234, 90. 855,64. 341,133.064, P <0. 0l ). Area under Receive Operated Curve (AROC) of all pRNFL parameters in early glaucoma except nasal ( P > 0. 05 ) and mGCC parameters had significantly diagnostic capability ( Need to be corrected by authors) ( pRNFL:0. 796 ±0. 049;mGCC:0. 748 ±0. 055, P <0. 05). As to the whole glaucoma, AROC of pRNFL and mGCC parameters had significantly diagnostic capability ( pRNFL:0. 889 ±0. 029; mGCC: 0. 862 ±0. 034, P <0. 01 ). Through AROC pairwise comparisons, the diagnosticpower of almost pRNFL and mGCC parameters had no difference ( P > 0. 05) except that temporal, superior pRNFL thickness were significant higher than focal loss of volume (FLV) of mGCC ( P < 0. 05 ). Conclusion The measurement of pRNFL thickness might still be used as a main method on diagnosis of glaucoma and mGCC could serve as a new beneficial complement tool for detection of glaucoma.
