Objective:To investigate the clinical effect of cluster nursing on the prevention of perioperative urinary catheter associated urinary tract infection (CAUTI) in patients with spinal fracture.Methods:A retrospective case-control method was used to select 160 patients with spinal fracture admitted to the department of spinal cord injury in emergency care from January 2018 to March 2020 in the Department of Orthopaedics General Hospital of Chinese People′s Liberation Army as study subjects, 80 patients admitted to the department of spinal cord injury from January to December 2018 were set as the control group, and 80 patients admitted from January 2019 to March 2020 as the observation group. The control group was given standardized clinical nursing measures during the perioperative period, while the observation group was given cluster nursing measures. The duration of indwelling of catheters, the incidence of catheter reinsertion and the incidence of CAUTI were compared between the two groups.Results:The catheter indwelling time in the observation group was (3.37±0.64) days, lower than that in the control group (6.35±1.52) days. The incidence of catheter insertion and CAUTI was 5.00%(4/80), 3.80%(3/80) in the observation group, lower than 11.30%(9/80), 11.60%(13/80) in the control group. The differences were statistically significant ( χ2 values were -2.927, -2.654, all P<0.05). Conclusions:Cluster nursing intervention for patients with spinal fracture in the perioperative period can effectively shorten the catheter indwelling time, reduce the incidence of catheter re-insertion and the incidence of patients with CAUTI, significantly improve the quality of clinical care in the department, and have positive significance for the treatment and rehabilitation of patients.

Objective To explore the influencing factors of urinary tract infection in patients with spinal cord injury in rehabilitation period, so as to provide the basis to minimize urinary tract infection.Methods The patients' information and the incidence of urinary tract infection (UTI) during the rehabilitation period of 503 cases of spinal cord injury admitted to the First Affiliated Hospital of PLA General Hospital from January 2013 to December 2015 were retrospectively analyzed. Logistic regression analysis was used to analyze the influencing factors of UTI in patients with spinal cord injury during rehabilitation period.Results The degree of injury, the site of injury, the way of urination, and the course of the disease were the factors affecting the incidence of UTI in the patients with spinal cord injury during the rehabilitation period (P<0.05). Conclusions The degree of injury, the location of injury, the way of micturition and the duration of disease are the influencing factors of UTI in patients with spinal cord injury during rehabilitation. As the course of disease goes on, we need to choose intermittent catheterization as a way of micturition according to the bladder function of patients with spinal cord injury.

Objective To investigate effects of physical exercise (PE) on object recognition memory in adult rats of postnatal isoflurane (Iso) exposures.Methods One hundred and ten postnatal 7-day SD rats (P7) were randomly divided into four groups: normal control group (Naive), Naive+PE group (received physical exercise in P21: a treadmill exercise 30min each day, 5 times/week, for 6 weeks), Iso group (three times of 2-hour Iso exposure in P7, P9, and P11), and Iso+PE group (received PE in P21 after postnatal Iso exposures). In P67, behavioral testing was conducted including open field and object recognition task (ORT), recording the time (Discrimination Ratios, DR) that rats spent on exploring each object, evaluating effects of PE on object recognition memory.Results There was no significant difference in influence of PE on open field testing in all of the groups (P>0.05). Compared with Naive, there was no group difference in DR (P>0.05) for all groups, but the DR of Iso male rats was significantly higher than that of Naive female rats in P67, with significant difference (P=0.034). Compared with non-PE groups, whether or not postnatal Iso exposures, the DR of PE male groups was significantly higher (compared with Naive and Iso group:P67,P=0.050,P=0.017; P95,P=0.037,P=0.019); in female rats, the DR for ISO+PE group was lower than that of Iso group in P67 (P=0.036), but the DR of Naive+PE group was higher than that of Naive group in P95 (P=0.004). Compared with male rats, the DR of non-PE female rats was significantly higher in P67 (vis. Naive and Iso group:P=0.022,P=0.011); but in P95, the DR of non-Iso female groups was significantly higher than that of male groups (vis. Naive and Naive+PE:P=0.008,P=0.017).Conclusions There is no obvious impact of postnatal Iso exposures on object recognition memory of adult rats. These Results also indicate that postnatal PE could improve object recognition memory of non-spatial learning in adult rats. In addition, exercise benefits have gender differences.

Objective To investigate influence of continued-nursing on physical and mental health for elderly patients with spinal cord injury.Methods A total of 80 elderly spinal cord injury patients (ASIA grade A) were selected in our department and divided into observation and control groups based on random number table method.The control group received conventional nursing and discharge guidance, while observation group received continued-nursing for 6 months after discharge, including telephone follow-up, family visit, and theme education activities.Self-care ability and psychological states before and after intervention were evaluated.Results The scores of Functional Independence Measurement (FIM), HAMA, and HAMD showed no significant difference in both groups before intervention(P>0.05).However, the scores above in observation group had significant difference after 6 months of continued-nursing than that of control group (P<0.01).The incidence of complication in observation group was lower.Conclusion Continued-nursing can improve the rehabilitation adherence and self-management ability of elderly spinal cord injury patients after discharge, and reduce the incidence of complications.

Objective To investigate effects of isoflurane anesthesia of different time interval on acute injury of brain function in neonatal rats with consistent total time of isoflurane anesthesia. Methods Seven-day neonatal Sprague-Dawley (SD) rats were randomly divided into normal control group (breathe the air), continuous anesthesia group (a single 6-hour exposure to 1.5% isoflurane), and intermittent anesthesia 1 day and 3 days groups (three times of 2-hour exposure to anesthesia with an interval of 1 day or 3 days), 12 rats in each group. The ratio of male to female was 5:7. They underwent the test of learning and memory in the radial arm maze (RAM) 21 days after birth, twice a day for 4 days. The number of entry into wrong arms, number of repeated errors, number of total arm entries, and time for completing the task were recorded for evaluation of effect of neonatal isoflurane on cognitive behavior in rats. Results ① Compared with normal control group, the percentage of number of errors > 3 in anesthesia of 3-day interval group was significantly decreased (33.3% vs. 46.9%, P < 0.05), the percentages of repeated errors > 0 and total arm entries > 8 were significantly increased (33.3% vs. 18.8%, 27.1% vs. 13.5%, both P < 0.05), but there were no statistically significant difference in the percentage of mistake number > 3 between continuous anesthesia group, interval anesthesia 1-day group and the normal control group (44.8%, 44.8% vs. 46.9%), the percentages of number of repeated mistake > 0 and total arm entries > 8 in above three groups were slightly increased as compared with those of normal control group (27.1%, 22.9% vs. 18.8%, 20.8%, 21.9% vs. 13.5%, all P > 0.05). No statistical differences in completing the task among normal control group, continuous anesthesia group, interval anesthesia 1 day and 3 days groups were found (minutes: 1.32±0.91, 1.54±1.05, 1.46±0.86, 1.38±0.79, all P > 0.05). ② It was found by gender analysis that the percentages number of repeated errors > 0 and total arm entries > 8 were significantly lower in female rats than those in the male rats only in normal control group (5.0% vs. 28.6%, P < 0.01; 5.0% vs. 19.6%, P < 0.05). There was no obvious gender difference in exposed groups. ③ Compared between groups of female rats, the percentages of repeated mistake > 0 in continuous anesthesia group, interval anesthesia 1 day and 3 days groups (25.0%, 25.0%, 30.0% vs. 5.0%, P < 0.05 or P < 0.01) and the percentage of total arm entries > 8 in interval anesthesia 1 day and 3 days groups were significantly higher than that of normal control group (22.5%, 25.0% vs. 5.0%, both P < 0.05). No significant difference about the RAM task in male rats of all the four groups was found. Conclusions Different time interval of neonatal isoflurane exposure may develop certain degree of acute brain injury in rats, characterized by cognitive function. Prolongation of the interval time significantly enhanced long-term memory in rats. Multiple neonatal exposures to isoflurane were associated with greater cognitive impairment than a single exposure. In addition, isoflurane can significantly increase cognitional functional disorder in the female, not in the male rats.

BACKGROUND:Surgical treatment is commonly used for decompressing the spinal cord in multilevel cervical spondylotic myelopathy, but the optimum anterior cervical reconstructive method has not been determined. OBJECTIVE:To compare and analyze the biomechanical characteristics of four anterior cervical reconstructive techniques in the surgical management of multilevel cervical spondylotic myelopathy utilizing the three-dimensional finite element model. METHODS:A three-dimensional finite element model of an intact C2–7 segment was developed and validated based on healthy adult male CT images. Four additional models were developed from the fusion model, including anterior cervical discectomy and fusion, anterior cervical corpectomy and fusion, anterior cervical hybrid decompression and fusion and anterior cervical discectomy and fusion with Cage alone. Von Mises stresses on the plate and the disc of adjacent levels (C2/3, C6/7) were comparatively analyzed. RESULTS AND CONCLUSION:(1) The C2/3 disc stress in flexion, extension, lateral bending and rotation condition was significantly higher than the C6/7 disc in 4 anterior cervical reconstructive techniques, and the adjacent disc stress (C2/3, C6/7) was lowest in the anterior cervical discectomy and fusion with Cage alone, and highest in the anterior cervical corpectomy and fusion. (2) The stress at the plate-screw interface was highest in the anterior cervical corpectomy and fusion, and lowest in the anterior cervical discectomy and fusion. (3) In conclusion, among the four anterior cervical reconstructive techniques for multilevel cervical spondylotic myelopathy, the anterior cervical discectomy and fusion with Cage alone makes little effect on the adjacent disc stress, which might reduce the incidence of adjacent segment disease after fusion. However, the accompanying risk of the increased incidence of cage subsidence should never be neglected.

OBJECTIVETo explore the effects of early intervention of acupuncture on urinary function reconstruction of neurogenic bladder after spinal cord injury, so as to find the optimal treatment timing of acupuncture.

METHODSFifty-three patients of neurogenic bladder after spinal cord injury were randomly divided into a prior-to-catheter group (25 cases) and a posterior-to-catheter group (28 cases). For the prior-to-catheter group, one week before the removal of catheter, acupoints on the abdomen and back such as Guanyuan (CV 4), Zhongji (CV 3), Baliao (Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33), Xialiao (BL 34), Jiaji (EX-B 2) and acupoints at distal end such as Zusanli (ST 36) and Sanyinjiao (SP 6) were selected; after the catheter removal, simple method. of water column was used to measure bladder capacity pressure to classify the type of bladder, and then different acupuncture manipulations were given; intermittent catheterization was performed if condition was allowed. The posterior-to-catheter group applied identical treatment after removal of catheter as the prior-to-catheter group. The treatment was given 5 times per week; after one-month treatment, five aspects including the time of first effective urination, time of establishing reflex urination, average residual volume of urine, time of residual urine less than 100 mL and quality of life (QOL) were evaluated.

RESULTSAfter treatment, the time of first effective urination, time of establishing reflex urination, average residual volume of urine and time of residual urineless than 100 mL in the prior-to-catheter group were all superior to those in the posterior-to-catheter group (all P<0. 05) ; the score of QOL was improved in two groups after treatment (both P<0. 01), but the difference between two groups was not statistically significant (P>0. 05); each index of urination function was not significant among patients with different injured segments of spinal cord (all P>0. 05).

CONCLUSIONThe early intervention of acupuncture (prior to catheter) has obvious improving function on establishing balanced bladder in patients with neurogenic bladder after spinal cord injury, which is superior to acupuncture intervention after removal of catheter, however, the effects of different injured segments on establishing balanced bladder are not different.
