Objective To explore the best methods of catheterization in patients with neurogenic bladder using clean intermittent self-catheterization. Methods From December, 2014 to December, 2015, sixty patients with neurogenic bladder were equally divided into observation group who were taught the non-contact clean intermittent self-catheterization, and control group who were taught routine clean intermittent self-catheterization. Their materials, times to learn, and the incidence of catheter contamination and urinary tract infection were compared. Results The observation group mastered the catheterization in fewer times of learning than the control group (Z=-4.400, P<0.001). The incidence of catheter contamination (χ2=5.880, P=0.015) and urinary tract infection (χ2=4.043, P=0.044) were less in the observa-tion group than in the control group. Conclusion Non-contact clean intermittent catheterization is beneficial to manage neurogenic bladder.

Objective To document and analyze thepeak force and work during isokinetic pedaling at different linear speeds and the flexion-extension peak force ratio.Methods Thirty healthy adults were tested using the Legpress system of the IsoMED 2000 apparatus.Peak force,work and the flexion-extension peak force ratio were recorded and analyzed during isokinetic pedalingat 5 and 50 cm/s.Results The peak force applied and work done by the lower limbs were both significantly lowerwhen pedaling at 50 cm/s than at 5 cm/s.There was no significant difference in peak force or work between the left and right legs at 50 cm/s.The peak force ratio at 50 cm/s was significantly higher than at 5 cm/s.Conclusion The mechanical characteristics of the leg muscles during isokinetic pedaling vary greatly.It is advisable to choose different linear speeds or training modes accordingly.

Objective To explore the effect of infrasound on the expression of glial fibrillary acidic protein (GFAP) after cerebral ischemia/reperfusion in rats. Methods The model of cerebral ischemia/reperfusion in rats was induced with intraluminal middle cerebral artery occlusion (MCAO) with nylon monofilament suture. 36 male adult Sprague-Dawley rats were randomly divided into sham group (n=12),model group (n=12) and infrasound group (n=12), then each group was randomly divided into 3 d and 7 d subgroups, with 6 rats in each subgroup.The infrasound group was treated with infrasound for 2 h every day 12 h after operation, the model group was treated in the same way turning off the power, the sham group received no treatment. They were evaluated with the modified Neurological Severity Score (mNSS) 3 and 7 d after treatment (before being executed), and brain tissue slices were immunohistochemically stained to observe the expression of GFAP around the ischemic sites. Results Compared to the model group, the mNSS score in 7 d infrasound group decreased significantly (P<0.05), the integral optical density (IOD) of GFAP around the focus was significantly higher in the infrasound group than in the model group (P<0.001). Conclusion Infrasound can increase the expression of GFAP after cerebral ischemia/reperfusion in rats.

Objective:To explore the difference in neurotransmitter levels between persons who had been comatose after a brain injury and healthy counterparts, and to explore the relationship between neurotransmitters and different states of consciousness.Methods:A total of 52 persons with brain injury were analyzed retrospectively and divided into a coma group of 30 with Glasgow coma scale scores ≤9 and a sober group of 22 with scores >9. γ-GABA, 5-hydroxytryptamine, noradrenaline and dopamine levels were measured using encephalofluctuography and compared between the two groups.Results:The levels of all of the neurotransmitters tested were significantly lower in the coma group than in the sober group. There were, however, no significant differences between the two groups in terms of relative levels of the neurorsmters. Logistic regression showed that dopamine deficiency is an important risk factor for coma after a brain injury.Conclusions:Most neurotransmitters decrease significantly among those comatose after a brain injury. Dopamine deficiency seems to be a risk factor for the incidence of coma. Therefore, drugs or rehabilitation therapies which can improve dopamine levels can be considered to help coma patients regain consciousness.

Objective To explore the implementation effects and application value of the Clinical Rehabilitation Integration Plan based on the graded management of rehabilitation treatment programs in a 3A general hospital.Methods The details of the programme were firstly formulated according to the needs of clinical rehabilitation and the implementation plan was formed,and then the integrated clinical rehabilitation work was carried out for 1 year accordingly,and finally the effects before and after the implementation of the programme were compared and analysed by selecting the indicators of departmental operation and patient satisfaction.Results The rehabilitation programme was classified into 4 levels according to the degree of technical difficulty and medical risk,and its connotation and management requirements were defined in detail.The implementation of the programme included organisational structure,training and assessment,authorisation management and quality control.The programme was carried out in 8 clinical departments in the hospital,and the overall willingness of the clinical departments to develop early rehabilitation was improved since 2022.Conclusion This program can improve the operational efficiency of clinical departments and patient prognosis.

Objective:To explore the effect of low frequency magnetic stimulation on myelin and inflammation in the callosum of demyelinated mice.Methods:Thirty-six 6 to 8-week-old male C57BL/6J mice were randomly divided into a control group, a cuprizone (CPZ) group and a magnetic therapy group. The CPZ group and the magnetic therapy group had demyelination induced by feeding a mixed diet containing 0.3% CPZ for 6 weeks, while the control group was given conventional food. The magnetic therapy group was given 50Hz 10mT magnetic stimulation during the 6 weeks for 20min daily, 5 days a week. The body mass of each mouse was observed every 7 days. At the end of the 6th week elevated cross maze experiments were conducted to observe any anxiety state. The myelin sheath in the corpus callosum was observed using Luxol fast blue staining and myelin basic protein (MBP) immunohistochemistry Tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the corpus callosum were detected using enzyme-linked immunosorbent assays.Results:After the 6 weeks of treatment, the average body mass of the mice in the magnetic therapy group had improved significantly compared with the CPZ group. The CPZ group′s times in the elevated cross maze experiments were significantly shorter than those of the control group and also shorter than those of the magnetic therapy group. The Luxol staining showed significant myelin loss in the corpus callosum of the CPZ group, but compared with the CPZ group the average loss of myelin in the magnetic therapy group was significantly less. This was further confirmed by the MBP immunohistochemistry. Compared with the control group, the average expression of MBP in the CPZ group was significantly reduced, while in the magnetic therapy group it was significantly increased. Compared with the control group, the average TNF-α and IL-1β levels in the corpus callosum of the CPZ group increased significantly, but compared with the CPZ group the average levels in the magnetic therapy group had decreased significantly.Conclusions:Low frequency magnetic stimulation improves the body weight and anxiety state of mice. That is probably related to less myelin loss and inhibited inflammatory response in the corpus callosum.
