ABSTRACT

Objective:To observe the relationship between bone metabolism biochemical markers and clinic features in patients with spinal cord injury. Methods:From July, 2018 to December, 2019, totally 135 patients with spinal cord injury were enrolled. They were assessed with American Spinal Injury Association Impairment Scale (AIS). β-collagen type I C-terminal telopeptide (β-CTX), total N-terminal propeptide of type I precollagen (TP1NP), 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH), serum calcium and serum phosphorus were measured. The level of TP1NP, β-CTX, 25(OH)D and PTH among clinical characteristics (gender, age, disease course, AIS grade and so on) were analyzed. Results:The levels of β-CTX and 25(OH)D were lower in women than in men (|t| > 2.044, P < 0.01). There was difference in the level of 25(OH)D among different ages (F = 3.156, P < 0.05). The levels of β-CTX and TP1NP increased in the first four months after spinal cord injury, and decreased then; while the level of PTH decreased in the first four months, and increased then (P < 0.001). The level of β-CTX was lower in patients of AIS D than in patients of AIS A and C (t >2.679, P < 0.05). The level of TP1NP was higher in paraplegics than in quadriplegics (Z = -2.035, P < 0.05). The level of β-CTX was higher in patients with fractures or surgeries involving bone than in patients without fractures or surgeries involving bone (t = 2.169, P < 0.05). There was no difference in all the bone metabolism markers between patients with and without lower extremity motor function (t < 0.839, Z < 1.822, P > 0.05). The ratio of 25(OH)D deficience was 85.19%. Conclusion:Bone conversion was active in the first four months after spinal cord injury, and decreased gradually then, which may be related to fractures of spine or surgeries involving spine after injury. The effect of spinal cord injury on bone metabolism markers is not clear. Most of patients with spinal cord injury were lack of vitamin D.

ABSTRACT

Objective:To investigate the occurrence and related factors of autonomic dysreflexia (AD) during intermittent catheterization in patients with spinal cord injury (SCI). Methods:Case control study was used in this study. Intermittent catheterization was performed on 44 SCI patients hospitalized from April, 2019 to April, 2020, The data of age, gender, time after injury, segment of injury, degree of injury, resting blood pressure, immediate blood pressure after catheterization, catheterization numbers, catheterization volume and duration of catheterization were collected. Descriptive analysis and binary Logistic regression analysis were used to analyze the occurrence and related factors of AD. Results:Totally, AD happened in 26 (59.1%) patients. Urethral catheterization was done 1738 times, out of which AD accounted for 187 times (10.8%). The risk of AD increased with the time after injury and age (P < 0.05). The probability of AD was lower in T7 SCI and below than in T6 SCI and above (P = 0.002). Catheterization numbers, gender, degree of injury, catheterization volume and duration of catheterization were not influencing factors of AD (P > 0.05). Conclusion:It is necessary to have a full understanding for the occurrence of AD in patients with SCI during intermittent catheterization. For patients with SCI in T6 and above, long time after injury and elderly patients, routine monitoring of blood pressure during intermittent catheterization is recommended to detect and deal with AD in time.

ABSTRACT

Objective:To explore the clinical manifestations and MRI features of pediatric spinal cord injury (SCI) after back bend. Methods:A retrospective study was performed. All the medical records and MRI images of children with SCI after back bend were identified in Beijing Bo'ai Hospital from January 1st, 2002 to August 31st, 2020. Results:A total of 120 SCI children after back bend were reviewed, out of whom 119 cases were girls, one case was boy. The age ranged from 38 to 162 months, with the median age of 76 months. More cases were discovered in July and September every year (32 cases, 26.7%), as well as in weekends (67 cases, 55.8%). The main clinical manifestations were sensory and motor dysfunction of both lower limbs (120 cases, 100%), bladder and bowl incontinence (120 cases, 100%). The common first symptoms included sudden attack of lumbar pain (39 cases, 32.5%), lower limbs paralysis (30cases, 25.0%) and leg pain (10 cases, 8.3%). The peak time of symptoms ranged from five minutes to two days, with the median time of 50 minutes. The MRI features of 104 children with SCI within one week after back bend were as follows: the abnormal signals of MRI in spinal cord involved lower cervical and all the following segments of spinal cord. The number of the segments of spinal cord with abnormal signals ranged from two to 15, with the median of seven segments. The most common segments with abnormal signals were T9 (96 cases, 92.3%), T10 (96 cases, 92.3%) and T11 (90 cases, 86.5%). Among the cases followed up, 48 cases with complete injury demonstrated a vast and serous spinal cord atrophy (SCA) below the injury segments as early as 37 days after the injury, the SCA would become worse at the chronic stage and maybe involve the spinal cord above the injury segments. In 31 cases with incomplete injury, the abnormal signals of MRI in spinal cord were limited in the lumbar enlargement, with a various degree of SCA at the late stage. All the cases were diagnosed as SCI without radiologic abnormality, out of whom 89 (74.2%) cases suffered from thoracic complete SCI, 31 (25.8%) cases suffered thoracic or lumbar incomplete SCI. The common complications included scoliosis, hip joint dysplasia, urinary tract infection, hydronephrosis, osteoporosis, pathological fracture of lower limbs and valgus knee. Conclusion:The main clinical symptoms of pediatric SCI after back bend were sudden lumbar pain, sensory and motor dysfunction of both lower limbs, and bladder and bowl incontinence. Most of the cases were thoracic complete SCI, the MRI features at the early stage were multiple segments of abnormal signals of spinal cord around T9 and T10, and later an extensive severe SCA below the injury segments to the conus medullaris, accompanied by the SCA above the injury segments.

ABSTRACT

Objective:To investigate the outcome of neurological function and the clinical characteristics of complications in children with spinal cord injury. Methods:From 2011 to 2019, children under 15 years old with spinal cord injury were selected in our hospital. Their level of injury and American Spinal Injury Association Impairment Scale (AIS) at one month, three months and one year were recorded. And the complications such as pressure ulcers/scald, urinary tract infection, hydronephrosis/vesicoureteral reflux, constipation, osteoporosis/fracture, deep vein thrombosis, neurodynia, heterotopic ossification, scoliosis and hip dysplasia were analyzed. Results:Of 159 individuals, 41 were boys and 118 were girls, the average age at injury was (6.08±2.57) years. The main cause of spinal cord injury was sports accidents (47.8%), and the main injury sites were thoracic spinal cord injury (89.3%). The cause of spinal cord injury was correlated with age at injury (r = -0.160, P = 0.044), gender (r = -0.458, P < 0.001) and injury sites (r = -0.249, P = 0.002). Complete spinal cord injury counted for 71.7%, and the AIS grade at one month was correlated with that at twelve months (r = 0.984, P < 0.001). The main complications were urinary tract infection (69.2%), constipation (67.9%), hydronephrosis/vesicoureteral reflux (37.7%), scoliosis (25.8%) and hip dysplasia (25.2%). The incidence of ulcers/scald was correlated with injury site (r = 0.179, P = 0.024). The AIS grade three months after injury was significantly correlated with urinary tract infection, constipation, scoliosis and hip dysplasia (|r| > 0.227, P < 0.01). The incidence of ulcers/scald was correlated with osteoporosis/fracture (r = 0.208, P < 0.01). The incidence of urinary tract infection was significantly correlated with hydronephrosis/vesicoureteral reflux, constipation, scoliosis and hip dysplasia (r > 0.261, P < 0.001), as well as osteoporosis/fracture (r = 0.195, P < 0.05). The incidence of hydronephrosis/vesicoureteral reflux was significantly correlated with constipation, osteoporosis/fracture, scoliosis and hip dysplasia (r > 0.146, P < 0.01). The incidence of constipation was significantly correlated with scoliosis and hip dysplasia (r > 0.313, P < 0.01), as well as osteoporosis/fracture (r = 0.160, P < 0.05). The incidence of osteoporosis/fracture was significantly correlated with scoliosis and hip dysplasia (r > 0.342, P < 0.01). The incidence of scoliosis was significantly correlated with hip dysplasia (r = 0.818, P < 0.001). Conclusion:The recovery of neurological function after spinal cord injury in children is closely correlated to AIS. The outcome of complete spinal cord injury is poor. The common complications after spinal cord injury in children demonstrate specific age characteristics, and the incidence of urinary tract infection, constipation, hydronephrosis/vesicoureteral reflux, scoliosis and hip dysplasia are common complications, which need more attention.

ABSTRACT

Objective:To investigate the clinical characteristics of old patients with spinal cord injury. Methods:From January 1, 2013 to December 31, 2019, totally 386 old (≥ 60 years) patients with spinal cord injury were enrolled. Their gender, age, etiology, American Spinal Injury Association Impairment Scale (AIS) and complications were analyzed. Results:In the old patients with spinal cord injury, traumatic spinal cord injury was more common in males (71.17%) and non-traumatic spinal cord injury was more common in females (56.19%). Fall on level surface was the most important cause of spinal cord injury both in old men (28.83%) and women (24.76%). Tumor (19.05%) was the most common non-traumatic cause of spinal cord injury in old female patients. Cervical segment (78.46%) was the most common site of injury in old traumatic spinal cord injury, while thoracic segment (52.14%) was the most common site of injury in non-traumatic spinal cord injury. Grade D (38.08%) was the most common AIS grade, followed by grades C (28.76%), A (21.50%), and B (11.66%). Spinal canal stenosis (23.31%) played an important role in the etiology of old spinal cord injury. Neuralgia, venous thrombosis of lower extremities and urinary tract infection were the most common complications in old patients with spinal cord injury. Conclusion:Fall on level surface is the leading cause of spinal cord injury in old patients, and the proportion of fall in the etiology of old spinal cord injury tends to increase with age. It is important to take effective measures to avoid falling in the old adults to prevent spinal cord injury.

ABSTRACT

Objective:To explore the etiological features and prevention strategies for pediatric spinal cord injury (SCI). Methods:A retrospective study of etiology and demographics features was performed and all the children with SCI (less than 14 years old) were identified in our hospital from January 1st, 2015 to December 31st, 2019. Results:A total of 221 children with SCI were reviewed, with 62 boys and 159 girls. The age ranged from one to 13 years with the median age of six years old. Children aged four to seven years accounted most (55.7%), and were mainly girls (83.7%). Sports and leisure activities (78 cases, 35.3%), non-traumatic causes (56 cases, 25.3%), other traumatic causes (48 cases, 21.7%), transport activities (24 cases, 10.9%) and falling from height (12 cases, 5.4%) were the top five leading causes of pediatric SCI. Among the cases caused by sports and leisure activities, 96.2% (75/78) were related to back bend in dancing exercise, in which most were five to seven years old (80.0%), and all of them were thoracic cord injury without radiologic abnormality, in which 70.7% (53/75) suffered from complete SCI. Conclusion:Pediatric SCI after back bend in dancing exercise is increasing rapidly in recent years. More attention should be paid on education about professional evaluation and the risk of back bend before dancing exercise, and more protective measures should be implemented.

ABSTRACT

Objective:To investigate the test-retest reliability and inter-rater reliability of Numerical Rating Scale (NRS) for abnormal sensation points of patients with spinal cord injury (SCI). Methods:From October, 2016 to December, 2018, 69 patients with SCI were enrolled. Their impaired sensory points were measured with NRS. The score of sensory points was tested by examiner A firstly, and examiner B did the same work next day. Then, the examiner A retested the same patients after three weeks. Results:The Pearson correlation coefficients and intraclass correlation coefficient (ICC) of the test-retest reliability and inter-rater reliability for sensory score of both sides were all above 0.88 and 0.93 respectively (P < 0.001). The Pearson correlation coefficients and ICC of the sensory score of the different injury levels were all above 0.88 and 0.93 respectively (P < 0.001). Conclusion:NRS has high test-retest reliability and inter-rater reliability for the assessment at abnormal sensation points of patients with SCI.

ABSTRACT

To observe the morphology of corneal endothelial cells after femtosecond laser in situ keratomileusis ( Femto-LASlK) .METHODS:From May to September in 2013, 88 eyes of 45 patients with myopia who accepted Femto-LASlK were enrolled in this study. The morphology of central corneal endothelial cells was measured by a non-contact corneal endothelial cell analyzer before, 1mo and 1a after surgery. The number, density, average size, size standard deviation, size coefficient of variation and hexagonality of the corneal endothelial cells were observed. All the measurements were analyzed by statistical analysis.RESULTS: All patients underwent operation smoothly, and no complication was observed during and after surgery;One month after surgery, the endothelial cell density (ECD) was 2815. 34±297. 07/mm2, which had a 2. 64% decrease compared with preparative ECD (t=4. 60, P= 0. 00), there was no statistical significance between ECD measurements of 1mo and 1a after surgery ( P>0. 05 ); One month after surgery, the size standard deviation ( SSD ) was 118. 47 ± 31. 58μm2 , which increased significantly compared with the preoperative SSD(t=-3. 87, P=0. 03), there was no statistical significance between SSD measurements of 1mo and 1a after surgery ( P>0. 05 );After surgery, the number, hexagonality, average size and size coefficient of variation of the corneal endothelial cells didn't change statistically(P>0. 05).CONCLUSlON: ln the early period after Femto-LASlK, the ECD decreased slightly, however this kind of surgery did not have significant harm to the function of corneal endothelial cells, and the surgery didn't cause the progressive loss of corneal endothelial cells.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and tolerability of the fixed combination of amlodipine 5 mg/benazepril 10 mg once-daily therapy, compared with benazepril, 10 mg, monotherapy in patients with mild and moderate hypertension, and to evaluate the 24 h antihypertensive efficacy and the duration of action by ambulatory blood pressure monitoring.</p><p><b>METHODS</b>In a multicenter, randomized, double-blind, parallel controlled trial, 356 cases of hypertensive patients after 2 weeks wash-out, and then given 4 weeks of benazepril 10 mg monotherapy, 220 patients with mean seated diastolic blood pressure (SeDBP) remained ≥ 90 mm Hg (1 mm Hg = 0.133 kPa) were randomly divided into benazepril 10 mg/amlodipine 5 mg (BZ10/AML5) fixed-dose combination therapy group (once a day, n = 113), and benazepril monotherapy group (daily 20 mg, n = 107). In the two groups the patients with SeDBP ≥ 90 mm Hg were doubled the dosage of the initial regimen at the end of 4-week treatment for additional 4 weeks, and the patients with SeDBP < 90 mm Hg remained the initial regimen for additional 4 weeks. The primary endpoint was to evaluate the improvement of SeDBP at the end of 8-week treatment. There were 74 patients (the combination therapy group n = 38, monotherapy therapy group n = 36) completed the 24 h ambulatory blood pressure monitoring which was included in the final efficacy analysis.</p><p><b>RESULTS</b>The randomized, double-blind treatment for 8 weeks, the mean value of SeDBP reduction, the reaching target blood pressure rate and total successful response rate to the treatment (a SeDBP < 90 mm Hg or a decrease of 10 mm Hg or more from baseline) were (11.7 ± 6.8) mm Hg, 65.7% and 88.5% in the combination therapy group, respectively, and were (7.7 ± 6.9) mm Hg, 35.5% and 65.5% in the monotherapy group, respectively. There were statistically significant difference between the combination therapy and the monotherapy groups in all the 3 indexs (P < 0.001). The fixed combination significantly reduced systolic blood pressure (SBP) and diastolic blood pressure (DBP) values throughout the 24 h. The trough to peak ratios of DBP/SBP in the fixed compound of benazepril/amlodipine (10 mg/5 mg) and benazepril (20 mg) alone were 83.1%/76.0% and 85.8%/79.5%, respectively. Adverse events rates were 16.8% in the combination therapy group and 35.5% in the monotherapy group (P < 0.001).</p><p><b>CONCLUSIONS</b>The combination therapy with benazepril/amlodipine was superior to benazepril monotherapy and was well tolerated in patients with essential hypertension and allowing a satisfactory BP control for 24 hours.</p>
